WILLIAM: C. VOUG-H, OF VJATERLOO, NEW YORK.
PIANISSIMO DEVICE FOR PIANO-ACTIONS.
Application filed January 27, 1908.
To all whom it may concern:
Be it known that I, \VILLIAM O. VOUGH, of Vaterloo, in the county of Seneca and State of New York, have invented a certain new and useful Pianissimo Device for Piano- Actions, of which the following is a specification.
My invention has for its object the production of a pianissimo device for piano-actions which is particularly simple in con struction and effective in result; and to this end it consists in the combinations, constructions and arrangements hereinafter set forth and claimed.
In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.
Figure 1 is an elevation of this piano-ac-.
tion, the parts being shown in their normal position, and adjacent portions of the piano being also shown. Fig. 2 is a view of parts seen in Fig. 1 illustrating the position thereof when the soft pedal is depressed. Fig. 3 is an edge view of the detached wippen.
This piano-action includes a hammer, a key, power transmitting connections be tween the hammer and the key comprising a plurality of parts which have movement relatively to each other when being operated, means for varying the starting position of the hammer to change the length of the stroke thereof, and means for adjusting the power transmit-ting connections lengthwise when the means for changing the length of the stroke of the hammer is operated, so as to prevent the formation of gaps or spaces between the parts of the power-transmitting connections at any time during the operating of the hammer, and to reduce the motion transmitted to the hammer from the key through the power-transmitting connections when the stroke of the hammer is shortened.
1 is the hammer, and 2 the key. The power-transmitting parts between the hammer and the key include an abstract 3, a wippen at, and a jack 5.
6 is a hammer-rest which is operated by the soft pedal of the piano to vary the starting position of the hammer and thereby change the length of the stroke of the hammer.
The means for adjusting the power-transmitting connections lengthwise when the hammer-rest 6 is shifted, comprises an element '7 pivoted to the wippen 4- and nor Specification of Letters Patent.
Patented Mar. 22, 1910.
Serial No. 412,896.
mally out of position to transmit any motion when the key is actuated, but movable into such position when the hammer-rest 6 is shifted. Preferably, said element normally is located between the edges of the wippen nearest the contiguous parts of the power-transmitting connections, is pivoted at one end at 8 to the wippen t, between the pivot for the wippen and the pivot connecting the wippen and the abstract, and is provided with means, as an integral projection 9, intermediate of its ends having a rounded edge which slidably engages another of the parts of the power-transmitting connections, when said element '7 is moved on its pivot beyond one edge of the wippen into operative position. The free end of said element is engaged by a bar 10 connected to the hammer-rest by a link 11, so as to move with the hammer-rest. I
Preferably, the abstract 3 is pivoted at 12 directly to the wippen 1, and the ack 5 is carried by an angular member or lever which is pivoted at 13 to the wippen between the pivot for the wippen and the pivot 12, the jack being pivoted at let to one arm 15 of the angular member or lever, and the other arm 16 thereof being located in a recess in the wippen and normally bearing on the bottom of the recess so that when the key is operated the opposing normally engaged faces of the wippen and member will coact to cause said member to move with the wippen as one body. A spring 17 is interposed between the jack and angular member. When said element 7 is moved into operative position it moves beyond the engaging face of the wippen at the bot-tom of the recess in said wippen, and engages the opposing face of the arm 16, and moves the angular member on its pivot 13 away from the wippen, thereby raising the jack so that there is no space between the end of the jack and the butt 18 of the hammer. During the movement of the element 7 into its operative position, the wippen remains stationary. hen the key is depressed after the element 7 is in operative position the abstract acts directly upon the wippen and the element 7 serves to reduce the motion transmitted to the jack from the key.
What I claim is 1. In a piano-action, a hammer, a key, power-transmitting connections between the hammer and the key comprising a plurality of parts, means for varying the starting position of the hammer to change the length of the stroke thereof, and means for adjusting the power-transmitting connections lengthwise when the firstmentioned means is operated, the latter means comprising an element pivoted to one of the power-transmitting parts and having a face for slidably engaging another of said parts, said element being normally out of position to transmit motion from one part to another when the key is operated, and being connected to the firstmentioned means and movable thereby for adjusting the power-transmitting connections lengthwise, substantially as and for the purpose described.
2. In a piano-action, a hammer, a key, power-transmitting parts between the hammer and the key including a wippen, an abstract connected to the wippen and a jack connected to the wippen, means for varying the starting position of the hammerto change the length of the stroke thereof, and an element for adjusting the power transmitting parts lengthwise, said element being pivoted to the wippen and disconnected from the abstract and the jack, and normally out of position to transmit motion from one of the power-transmitting parts to another when the key is operated, and being connected to said means and movable thereby into position to adjust the powertransmitting connections lengthwise, snbstantially as and for the purpose set forth.
3. In a piano-action, a hammer, a key, power-transmitting connections between the hammer and the key comprising a wippen, an abstract pivoted to the wippen, a jack, and a member interposed between the wip pen and the jack and pivoted to the wippen and the jack, an element pivoted to the wippen and slidably engaging said member, and means for varying the starting position of the hammer to change the length of the stroke thereof, said means being connected to said element, substantially as and for the purpose specified.
