upright piano hammer mechanism

Often copied but never equaled, the patented Yamaha aluminum action rail helps assure our piano keyboards are resistant to tiny fluctuations in humidity and temperature over time. The weight at the left end of the key (point e) will push the key downwards if there is no force acting at theright end. In accordance with the present invention, however, the use of the above-described back check mechanism succeeds in incorporating the double escapement mechanism into a typical upright piano without presenting such a problem. Hammer mechanics. The back check member 24 is attached to the terminal end of the horizontal arm 21, and this terminal end defines an enlarged portion 21a. If one tries to do the same on an upright piano, the key will go back down, but the hammer wont be able to hit the string. How Does The Upright Piano Work? which is the escapement mechanism that allows the piano. BB, which go through the metal plate and into the wooden frame or pin block. This being the only office of the right pedal, it is readily seen that this pedal does not increase the loudness, but simply sustains any number of tones struck successively, giving the effect of more volume. The adjustment screw 38 serves to adjust the inclination of the repetition lever (the second lever 33) with respect to the wippen 12, and the lower end of the adjustment screw 38 is normally maintained in contact with the wippen 12.

They were designed to be a counterpoint to the larger, heavier full-sized upright pianos. 48 Yrs in Business - 21st Year Online. So far the team has conceived two ideas that are still a work in progress and another design that has been discarded. In actions of this kind, the extensions remain in place at all times and the trouble of placing them properly on the bottom when replacing the action is obviated. 5) or upright piano (FIG. Schaff Piano Supply. At the turn of the century, Schwander-Herrburger merged with Brooks, giving us the Herrburger-Brooks piano action, which was the definitive piano action of the twentieth century. Pictogram isolated on white background The leaf spring 41 has a long leg 41a and a short leg 41b. Upright pianos cannot be changed outside of what is theoretically ideal for each particular instrument; otherwise, double-striking (bouncing hammers) and issues of hammer return out way any advantage of changing how the instrument feels. The 2000s-era grand action is a distant descendant of Cristofori's original. Bl, bridle. The cut shows where the bridle is fastened in the hammer butt by being put into the hole in the butt, and the back catch stem covered with glue and driven in by it which precludes all possibility of its coming loose. About this item: In the 19th century, the English action was further modified by French builders, notably in the invention of the repetition lever, which facilitated rapidly repeating notes. The figures below show an animation of how both actions operate, and one can clearly see the similarities between the two mechanisms. Both actions propel a felt hammer in order to hit the strings, and as soon as the hammer hits the string, it must be released back immediately to allow string vibration. The force applied to the piano key K is smoothly transmitted through the intermediary of the pillar 9, the wippen joint 10 and the wippen heel 11 in the upward direction as viewed in FIG. The previously described object is also achieved by the provision in the present invention of a back check mechanism in an upright piano in which a depressing force applied to a piano key is transmitted to an L-shaped hammer through the intermediary of an action mechanism to cause the L-shaped hammer to strike a string, the mechanism comprising: a back check member provided on one end of a horizontal arm of the L-shaped hammer; a resilient wire screwed into a wippen of the action mechanism and extending through a through-hole formed in the horizontal arm of the L-shaped hammer; and. Approximate length of bass hammers: 2-9/16" (64 About this item: The mortise in the wooden cap on top of the key at this point is lined with bushing cloth which holds the key in position laterally, and prevents looseness and rattling, yet allows the key to move easily. $2.95 - $24.95. . said wippen joint extending between said pillar and said wippen heel, contacing said wippen heel, and pivotable as the piano key is moved from said normal position to said depressed position to transmit thrust from the piano key that pivots the wippen; a double escapement mechanism supported by said wippen and operatively connected to said L-shaped hammer for transmitting pivotal movement of the wippen to the L-shaped hammer. 3. When the key is pressed down, this new action works like atraditional upright action, the workings of which have been explained in an earlier paragraph. The little diagram up above is a hugely simplified version of what happens in a real piano. In such actions the extension is invariably provided with the extension guide. Upright Piano Pedals - Steinway K and 45" $ 145.00. I claim: 1. Its purpose is to assist the hammer to return quickly by hanging to it with the weight of the wippen, extension, jack, etc., when the key is released. This rail is absent in some actions, in which case the back of the jack is felted and strikes against the "back catch," which is also felted on inner side. Self-taught, this 61-year-old former apprentice watchmaker-turned professor of mathematics and auditor of weights and measures had wanted to devote himself to the reparation of the clock with a very complex mechanism since his childhood. Grand or Upright? An upright piano hammer action mechanism taken from a ruined piano from early 1900s.Design and Analysis of Mechanical SystemsFall 2020 The first stopper 34 is attached to one end of a regulating screw 34a which extends through the fixed bracket 22 and the fixed frame S.

We designed our own version of the repetitive mechanism. 1 includes a back check member 24 and a hammer check 25. Unfortunately, there we are certain that challenges will arise. The invention relates to a damper mechanism for upright piano, comprising a damper felt mounted on a damper wood, and in which the damper wood is equipped with a guide stem directionally adjusted perpendicularly to the plane of the strings and guided to move reciprocally in a bore of a block fixed on a support independent of the mechanism controlling the hammers. M R, is the main rail; so called because the main constituents of the action are attached to it. Choose Options. W, is the wippen. We decided to order an upright action model from Ebay so that we can assemble it and then visualize the movement of the action. After Cristofori's death in 1731, a number of piano makers (for instance, Gottfried Silbermann) built pianos with actions that were essentially copies of Cristofori's. 1, with one end of the first jack 31a extending through the through-hole 37. a back-check mechanism for checking the hammer at a temporary position located between said string-striking position and said rest position when said hammer has pivoted from said string-striking position toward said rest position by said third pivotal amount as the piano key moves from said depressed position toward said normal position. BC, is the back check which is simply a piece of wood with a thick piece of felt glued to the inner face and suspended on a wire. 3. 3, the prior art disclosed in Japanese Utility Model Laid-open No. String 2. Also, the wippen can rotate freely around pulley (point p) and therefore the downward force at left end of the wippen (point h) would impart a counter clockwise moment which would be propel the back check (point c) in the direction of the returning hammer. If the button is too high, it does not throw or trip the jack in time to prevent blocking. In some cases the lead is inserted in the extreme back end of the key; in others it is put near the balance rail according to the requirement. $ 39.97. If a grand piano is played using this technique, a complete form of repetition can be performed. B P, is the balance pin. A crafstman holding a hand after working with repairs of the inside mechanism of an upright piano. 7500 Piano Items for Home & Business. The movement of the first lever 31 is limited by a first stopper 34 while the movement of the second lever 33 is limited by the aforementioned second stopper 35. Open upright piano mechanism with strings and hammers. Learn on the go with our new app. The good news is that we got spring break to catch up, so thats exactly what well do. The center-pin in the wippen is driven through a hole in which it fits tightly and immovably in the middle part, and it (the center-pin) is consequently stationary in the wippen. said second escapement means for pivoting said hammer only a first predetermined amount between said rest and said string-striking positions during pivotal movement of said wippen, and said first escapement means for pivoting said hammer only a second predetermined amount between said rest and said string-striking positions after the hammer has been pivoted said first predetermined amount by said second escapement means, said first and said second predetermined amounts being less by a third pivotal amount than the total pivotal amount which said hammer is pivotal between said rest and said string-striking positions; and. This was also meant to help us learn and determine a solution for the redesigned mechanism;moreover, having a functioning model would make explaining to other people what we are doing much easier. The piano action was the important innovation that Bartolomeo Cristofori created when he invented the piano in 1698. Hammer, strings, and the inner workings of an upright piano; slight antique effect in post processing . Interior Steel Core Damper spring rail 9.

When you press a key on the piano, its respective hammer strikes a string or a set of string which is tuned to the appropriate musical note. As there is more or less difference in the length of keys, and also in the weight of the hammers operated by them, some keys are leaded much more heavily than others. Solid Hard Plastic Handle For more information on Piano Tuning School, please . The special double-repetition mechanism of the grand piano. This arrangement contributes to the entire mechanism being compact, enables a positive catching of the hammer check 25 with the back check member 24, and effects a suitable balance of the action mechanism which influences key tough quality. Redesigned Hammers Thus, it would not be able to interfere with counterclockwise rotation of wippen by applying a clockwise moment. The first jack 31a is adapted to strike a hammer roller 35 attached to the underside of the horizontal arm 21 which provides support for the hammer H. The second jack 31b is integral with the first jack 31a, and is adapted to abut the first stopper 34 to shift the first jack 31a from the position at which a jack 31a would strike the hammer roller 36, thereby preventing the jack 31a from striking the hammer roller 36. This musical note is amplified by the wooden soundboard. 5360. Schaff Piano Supply. who invented the piano keyboard layout When the key is lightly pressed, the hammers do not move, but if they are pressed fast and hard, they do strike . This makes it the tallest of all the vertical pianos. The advantage of including ball bearings is that when the key is pressed down, the link, which also experiences an upward motion, would be able to fold onto itself. This "Viennese" action was widely used by makers in Vienna, and was the action of pianos played by Haydn, Mozart, and Beethoven. Toll Free 1-800-791-7144. Thus, this version of repetitive mechanism would enable a pianist to play two notes before the hammer return to its original position. Quick view. It used levers to magnify the small motion of the piano key into a large motion of the hammer, and was arranged so that the very last part of the hammer's motion before striking the string would be purely the result of inertia and not propelled by the key; this prevents the key from pressing the felt-covered hammer firmly into the string, which would damp and stop the string vibrations and the sound. Once the hammer reaches a distance of about 1/8 of an inch from the string, the jack makes contact with the let-off button (16). The lower end of the extension is felted. 1, thereby, enabling the upright piano to be played by practicing ordinary techniques. When a piano key is pressed, a corresponding hammer rises to strike the string (or strings) causing the highly-tensioned strings to vibrate. The bottom of the hole in the key fits closely around the balance pin; at the top, it is the shape of a mortise, parallel with the key, which allows the key to move only in the direction intended. Thank you for choosing this Kawai ES1 Digital Piano . Perhaps the best-known English piano action of the nineteenth century is the Brooks action of 1810. (The back catch has no mark in the cut, but is explained below in connection with the "back check."). At the top of each bracket is an opening to receive this bolt and a thumbscrew (not shown in the cut, being behind the hammer) which fastens the action securely in position. With the piano, a hammer strikes the string, whereas with a harpsichord, a mechanism plucks the string. The hammer plane should remain constant through its path of motion. It is held in position by the two screws shown in cut by which it can be adjusted or regulated. The action mechanism of a key consists of the key itself and all its appurtenances. TANAKA INTERNATIONAL CO., LTD., 855-20 SHIMOGO OGO, Free format text: U1. The inclination of the first lever 31 with respect to the wippen 12 is adjusted by adjusting the length of the portion of the adjustment screw 39 that projects from the first jack 31a and altering the state of contact between the adjustment screw 39 and a stopper 40 which is disposed upright on the wippen 12. In order to illustrate these topics, we have created a handy gantt chart for the first half of the year that reveals two concerning facts: We only have about a month to finalize our design, and perhaps more alarmingly, we only have 10 days for completing the first milestone (yikes). To study these problems, we researched if there had been any attempts at solving this issue, and we came across the Takumi piano modification. In the 1770s, the Augsburg builder Johann Andreas Stein developed an entirely new action in which the orientation of the hammer was reversed, with the hammer head closer to the player. Hammer: Felted mallet that's also used to produce a sound. This pressure brings the second jack 31b into contact with the first stopper 34. It consists of the following parts: the jack "to propell the hammer toward the strings"; the backcheck, "which catches the hammers"; the bridle wire and bridle strap "in uprights" pull back on the hammer, and also allows the whole mechanism to stay in-check when you take it out of the piano; An action mechanism of an upright piano for transmitting thrust between a key and a hammer of the piano, said action mechanism comprising: a piano key pivotally mounted in the piano about a fulcrum point between normal and depressed positions; an L-shaped hammer pivotally mounted in the piano and movable between a string-striking position at which the hammer contacts a string and a rest position, said L-shaped hammer including a horizontal arm extending generally horizontally when the hammer is at said string-striking position and a vertical arm extending generally vertically when the hammer is at said string-striking position, and said L-shaped hammer biased to said rest position; a wippen pivotally mounted in the piano and disposed between said piano key and said hammer for transmitting thrust from the piano key to the hammer when the hammer is depressed; a wippen heel extending from said wippen toward said pillar; a stationary shaft spaced from said wippen heel, said shaft having a longitudinal axis and mounted in the piano with said longitudinal axis immovably fixed in the piano; a wippen joint pivotally mounted in the piano via said stationary shaft about the longitudinal axis thereof. 1 with frictional resistance limited to an extremely low level. $65,000. 5" long 1, a plurality of piano keys K are arranged on a keyboard (not shown), and each of the piano keys K is supported on a key frame 1 fixed to a key bed (not shown). 4, such an arrangement requires a relatively large second wippen 11a, as well as a first wippen 11. The two fold link that got fold in the previous motion will unfold itself and apply a downward force at the left end of the wippen (point h). The repetition mechanism allows the pianist to quickly repeat a note without having to rely on the piano to reset the action. This prevents the hammer from bouncing off of the hammer rail (20) and re-striking the string. Soundboard and Frame The piano boasts a special rib configuration that strengthens the soundboard while the back post enhances rigidity, structural stability, and resonance. Since the hammers have less distance to travel this reduces the speed at which they hit the strings, and hence the volume is reduced, but this does not change tone quality in the way the una . Upright Piano Pedals; Piano Pedal Hardware . The hammer rail is held in position by the rod, shown under the hammer shank, which is hinged to the bracket at the lower end, and which allows it to be moved forward when the soft pedal is used. Other than creating an uneven feeling for pressing different keys due to springs deteriorating at different rates, this mechanism has another flaw: To play the key again, the key must completely reset back to its resting position. Oliver Esmonde-White shows off a piano hammer mechanism that he invented at his shop in Montreal on Friday, Jan. 21, 2022. Get the latest updates on new products and news.

The piano key K is attached to a central key frame 1a on the key frame 1 for facilitating a swinging motion of the key about a pin 2. We will have to fabricate some parts for the reset action to work properly, and there needs to be a mechanism that releases the hammer whenever it hits the string called the regulating button. Inspired by our grand pianos, our damping mechanism prevents the fallboard from dropping abruptly, guarding against accidental injury or damage. The energy of the vibrating string is transferred to the soundboard through a component called the "bridge" that is fixed to the top of the soundboard. 1. Upright Piano Hammers. Whenever we first saw the traditional upright action, one of our first instincts was to ask ourselves whether or not all those parts were really necessary, and the more we learned about the device, the more we realized how monumental the task ahead of us really is; however, we feel like our question still stands. The present invention relates to an improved action mechanism for pianos, in particular, upright pianos and. But according to this invention, the balance weight W may be provided in the boss portion 20 or the hammer wood 18. However, although a conventional type of upright piano may include the back check mechanism B as shown in FIG. The purpose of the regulating button is to throw the point of the jack out of the nose of the hammer butt, and allow the hammer to rebound from the string. A piano's keys control the hammer and the damper through an intricate mechanism, which is known as the piano's . Theories of Media, Design & TechnologySpring 2021. The hammers are not resting against the string. G P, is the guide pin, generally of oval shape, with the longest diameter in line with the key. To read a humorous explanation of the project and to learn about our initial thoughts please refer to our first blog: On this blog, we will discuss about our plans to move ahead with project, the progress we have managed to achieve so far, and some of the challenges we have come across. It is not smart to replace only a few. Accordingly, the pressure acting upon the second lever 33 supported by the repetition lever fork 15 causes the second lever 33 to rotate about the second stopper 35 in the counterclockwise direction only, and thus does not force the hammer roller 36 upwardly. With this arrangement, the positional relationship between the hammer check and the back check member can be easily adjusted at any time. FIG. Generally, the more expensive, higher echelon grand pianos have this feature. The two proposed designs might not work or survive scrutiny, the model of the upright action might not give the team an exact representation of how the upright works, or not having a model of the grand piano key to physically analyze will hinder our analysis; however, at least we are able to foresee these challenges, as Im certain we will have to face unforeseen issues that will sow up until its time for validating our designs. Application filed by TANAKA INTERNATIONAL CO Ltd. Bm, is a wooden block called the bottom; sometimes called the key-rocker. We will continue to do research on this and other proposed solutions, and we plan to validate our results using other measurable experiments to test for responsiveness, evenness, and how far the key must reset before it can be played again. [7] The illustration to the right is of a circa 1907 Wessell, Nickel and Gross upright action; the parts are listed below. Tuning Pins: Threaded steel "peg" usually around 1 1/2" long where every sting is wound. Howard Piano Industries. When pushing the half-blow rest-rail with the fingers in direction to the strings, the space between the hammers should remain the same. As a piano ages, the felt on the hammers that strike the strings wears down and hardens. This powder is a mixture of fibers, wood, and other materials, and it eventually turns yellow. Action mechanism of an upright piano United States Patent 4854211 Abstract: An action mechanism for a upright piano includes a back check mechanism having a back check member provided on the horizontal arm of a hammer arranged to strike a string and a hammer check disposed upright on a wippen constituting an escapement mechanism. The design shown above represents a hammer mechanism that is propelled by a gear and rack combination. In the action of the grand piano the keys are leaded in front of the balance rail instead of back of it. REDUCE HAMMER SHANK SIZE: This tool is used for reducing the size of hammer shanks to make them fit better with new hammers while keeping the shank's round diameter. hammers' mechanism, which means he strings will hit them when they are struck when keys are pressed is called, "action". It is an instrument that can bring out emotions by playing musical pieces with great expressiveness. They examined their success by simply showing that it can be played faster, but doesnt mention whether or not the key must go back to complete resting position to be played again. All Bugatti at Cit de l'Automobile in Mulhouse (Alsace) La Cit de l'Automobile, also known of Muse national de l'Automobile, is built around the Schlumpf collection of classic automobiles. Accordingly, although upright pianos may have various advantages such as their relatively small size, inexpensive price, and convenient operability, they are seldom used for public performances such as concerts. Artwork courtesy of US Patent and Trademark Office. In an effort to compensate for the missing information, we relied on our mechanical engineering instincts and learned from videos found online of a similar action piece that was already built. More specifically, the double escapement mechanism D includes a first escapement D, The first mechanism 6 includes a toggle mechanism 44 which has an actuating piece 44a and a pressing piece 44b and which is pivotally supported by a bracket 43 attached to the support frme S. The following is a description of the operation of the presently preferred embodiment of the invention with specific reference to FIGS. In general, in order to enable a rapidly repetitive striking of a piano string, it is necessary to employ a mechanism which acts according to the speed of depression of a piano key to return a hammer to predetermined position, which stops the return of the hammer at an intermediate position, or which limits the speed of return of the hammer utilizing the force of a spring or the like. We will attempt to explain the two surviving designs as best as we can, but keep in mind that neither has been completed and that one is the product of a fever dream caused by a tonsil infection (we wont tell you which one it is though). [5][6] One of the most well-known French piano actions was created by Jean Schwander in 1844 (the Schwander action is still used in Bechstein pianos) and improved upon by his son-in-law Josef Herrburger. Complete Catalog. It is to be noted that the term "back check mechanism (B)" used herein is defined as a mechanism which can be incorporated in any grand piano or upright piano and in which, while a hammer is returning reactively after striking a string, the hammer is received at an intermediate position between the striking position and the rest position, thereby allowing a jack to positively strike the hammer at the succeeding depression of the same piano key. Digital Pianos from CASIO - A Full, Special Sound and Playing Feel . Hammer shank 10. In some cheap actions the butt is joined to its flange g, by the means described under the head of wippen flange; but in this action the center-pin is held firmly in the butt by a small strip of brass containing a set screw; somewhat obscure in the cut, but discernible. Since the hammer roller 36 abuts the first and second levers 31 and 33, the horizontal arm 21 carrying the hammer H is moved counterclockwise to cause the hammer H to travel toward the string C as shown in FIG. On being hit, the string vibrates rapidly and produces the musical note. a back check mechanism including a back check member provided on one end of a horizontal arm of the L-shaped hammer and a hammer check upright on a wippen of the escapement mechanism.
