摘要： An adjustable friction grand piano hammer shank having bifurcated ends disposed on either side of a flange with a slot defined in each bifurcated end, a pivot pin receipt hole defined in each bifurcated end aligned with the slots, a strap having one end affixed to the bottom of one of the bifurcated portions extending therearound to form a loop around an adjustment screw with the strap's other end extending around the other bifurcated end to be affixed to the bottom of the other bifurcated end such that tightening the screw pulls on the strap and tightens together the portions of the bifurcated hammer shank ends above and below the slots to increase friction against the pivot pin and conversely, loosening the adjustment screw releases tension on the strap allowing the ends above and below the slot to be under less tension and reducing friction on the pivot pin.

摘要： The subject action is a modification of the traditional upright action. The traditional jack spring is eliminated. Its function is assumed by a jack/repetition spring, which is a compression spring adjustably mounted between the jack near the end that engages the hammer butt and a pilot attached to the back stop portion of the hammer assembly. The hammer return spring mounting enables adjustment of the range of force applied by the spring to the hammer. The force range magnitude is such that the hammer return torque is commensurate to the torque that would be applied by gravity if the hammer shank were mounted horizontally instead of vertically. The operating force of the jack/repetition spring is related to that of the hammer return spring in such a way that re-engagement of the jack with the hammer butt is assured before hammer return beyond the back-checked point. The ends of the jack/repetition spring are geometrically located to allow the elements of the action to keep in intimate contact after re-engagement, making possible the elimination of the bridle tape and wire, and to provide a function that feels smooth and tight, not loose. The interaction between the springs as applied produces enough return force on the key to allow use of weights in the played end of the key to provide the desirable inertial resistance of a grand action to the player's touch on the keys. With the subject action properly adjusted, the hammer assembly rests upon the jack, rather than the traditional rest rail and therefore there is space between the hammer shank and hammer rest rail when the action is at rest.
摘要翻译：主题行为是传统直立动作的修改。传统的千斤顶弹簧被淘汰。其功能由千斤顶/重复弹簧来承担，千斤顶/重复弹簧是可调节地安装在接近锤头踵的端部附近的千斤顶之间的压缩弹簧和附接到锤组件的后止挡部分的导向器。锤回位弹簧安装使得能够调节弹簧施加到锤的力的范围。力范围大小使得如果锤柄水平而不是垂直安装，则锤击返回扭矩与由重力施加的扭矩相当。千斤顶/重复弹簧的操作力与锤复位弹簧的操作力相关，使得在锤返回超过后检点之前，可以确保千斤顶与锤子对接头的重新接合。千斤顶/重复弹簧的端部几何定位以允许动作元件在重新接合之后保持紧密接触，从而可能消除绷带和线，并且提供感觉平滑和紧密的功能，不松动弹簧之间的相互作用在钥匙上产生足够的返回力，以允许使用键的弹奏端的重量，以提供对玩家对钥匙的触摸的宏伟动作所需的惯性阻力。在主体动作适当调整的情况下，锤子组件靠在千斤顶上，而不是传统的休息轨，因此当动作静止时，锤柄和锤子休息轨之间有空间。

摘要： A piano action mechanism wherein a shaft pin for rotatably supporting a rotatable member on a flange is carried in bearings formed of bushing cloth glued to the surface of bushing holes in the rotatable member. With a pin inserted through the cylinders of bushing cloth, the assembly is dipped in water, dried, dipped in a solution of resin bonded fluorocarbon solids, again dried and the pin removed, to provide a durable and stable bearing having a low coefficient of friction and which is essentially noise-free and insensitive to changes in temperature and humidity.

摘要： In the construction of a damper assembly for musical instruments, the conventionally used swingable damper lever for operationally relating a key to an associated damper wire is omitted and the swing movement of the key is either directly and indirectly converted into a corresponding fairly vertical movement of an elongated damper holder via a balance weight disposed to the bottom end of the damper holder in order to avoid undesired influences caused by swinging movement of any mechanical parts. Use of a plate type damper holder further advantageously prevents undesirable twist and dancing of the damper holder. Simultaneous, even and well-controlled pressure contact of the damper head with the vibrating string assures ideal damping and acoustic effects and use of detachable balance weight enables free adjustment of touch on the key.
摘要翻译：在用于乐器的阻尼器组件的构造中，省略了常规使用的可操作地将钥匙与相关联的阻尼线相关联的可摆动阻尼器杆，并且钥匙的摆动运动被直接地和间接地转换成相应的相当垂直的运动通过设置在阻尼器保持器的底端的平衡配重的细长阻尼器保持器，以避免由任何机械部件的摆动所引起的不期望的影响。使用板式阻尼器支架进一步有利地防止阻尼器保持器的不期望的扭转和跳动。阻尼头与振动弦的同时，均匀和良好的压力接触确保理想的阻尼和声音效果，并使用可拆卸的平衡重，可以自由调节钥匙上的触感。

摘要： The invention relates to musical instruments of the general class wherein a vibratile member - such as a wire or reed - is struck by a percussive means to produce a note. There is provided a method of controlling the return of the percussive means against a stop member, after striking the vibratile member, by providing inertial means which the percussive means strikes and to which the kinetic energy of the percussive means is transferred, thus eliminating rebound of the percussive means from the stop member. The invention has particular application to pianos, but is by no means restricted thereto.
