M. BEGKWITH. UPRIGHT PIANO ACTION. APPLICATION FILED LTULY 28, 1907.
UNITED STATES PATENT OFFICE.
MERRILL BEGKWITI-I, OF NEW YORK, N. Y., ASSIGNOR TO THOMAS SHERWOOD BOYD, OF
i NEW YORK, N. Y.
UPRIGHT-PIANO ACTION To all whom it may concern:
Be it known that I, MERRILL BEOKWITH, a citizen of the United. States, residing at New York city, Manhattan, county and State of" New York, have invented new and useful Improvements in Uprigliit-Piano Actions, of which the following is a specification.
This invention relates to an upright piano action which insures a quick repeating eil'ect and maintains the hammer butt and jack in their proper relative position, upon a depression of the soft pedal.
In the accompanying drawing: Figure 1 is a side view of my improved action, showing the normal position of the parts; Fig. 2 is a similar view, of portion of the action, showing the parts after the key has been depressed; Fig. 3 a front view of the hook and spring,
I and Fig. 4.- a section on line 4 4, Fig. 3.
The letter (1, represents the jack of an upright piano action b, is the hammer and b, the hammer-butt, to which is secured the bumper d, by arm (1. Y
The jack a, carries a bent pin or post 6, cmbraced by a vertically adjustable sleeve f, which is clamped to the post by set screw f To the sleeve f, is attached by screw f", a hook g, and a spring 7b, in front of the hook. The hook g, is slotted longitudinally as at g, and its beak g, is bent backwards, to be received within an inclined front notch 5 of butt Z). The spring 7t, is placed opposite slot g, so that it may enter the same. The upper free end of the spring extends forward to normally diverge from the hook g, (Fig. 1), and to engage a regulating button t, of bumer d. p Upon a depression of the key 7c, the hook g, is thrown forward to clear butt 7), while the spring h, is compressed, (Fig. 2). When the key is now part y or completely released, the spring h, will throw the jack back into reengagement with the butt, which is meanwhile held up by the spring. At the same time the hook g, will be carried backwards to Specification of Letters Patent.
Application filed July 23, 1907.
Patented May 5, 1908.
Serial No. 385,194.
reenter slot 7)", and then the hook by exerting a downward pressure upon the butt, will swing the hammer forward, t. 6., towards or against the hammer rail In this way a superior repeating effect is obtained. It will be observed that if the hammer is raised by the pianissimo pedal, (not shown), its butt will by the hook g, pull the jack and lower part of action up with it, while the key 76, weighted as at Zc, will follow the movement of the action. Thus the relative position ol all the parts will be maintained. By means of the sleeve f, the distance to which the hook projects above the ack, may be readily adjusted.
I claim:
1. An upright piano action provided with a ack, a hook and spring, means for securing the hook and spring to the jack, a hammerbutt engaged by the hook, and a bumper engaged by the spring, substantially as specilied.
2. An upright piano action provided with a jack, a slotted hook, a spring adapted to play in the hook-slot, means for securing the hook and spring to the jack a hammer-butt engaged by the hook, and a bumper engaged by the spring, substantially as specified.
3. An upright piano action provided with a jack, a pin secured thereto, a sleeve adjustably mounted upon the pin, and a hook and spring securedv to the sleeve, substantially as specified.
4. An upright piano action provided with a jack, a hook and spring, means for securing the hook and spring to the jack, a notched hammer-butt engaged by the hook, a bumper, and a regulating button on the bumper engaged by the spring, substantially as specified.
Signed by me at New York city, (Manhattan,) N. Y., this 22nd day of July, 1907.
MERRILL BECKWITH. Witnesses:
GEO. W. MOCARTHY, L. K. Wnrss.
