SELF-PLAYING MUSICAL INSTRUMENT.

Specification ofLetters Patent.

1 Patented Sept. 1, 190a.

' Application filed June 3,1908. Serial No. 436,383.

To all whom it may concern:

Be it known that I, WILLIAM J. PUBLow, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful :-Improvements in Self-Playing Musical Instruments, of which the following is a s )ecification, reference being had therein to the accompanying drawings.-

The invention relates to-new and useful.

improvements in automatic musical instruments, and consists particularly in the construction of the striking pneumatic, and in detail in the construction of the connection betweenthe movable member of the. striking pneumatic and. the lifter bar whereby'such a connection is simplified in construction and rendered noiseless in use, andwhereby any adjustment desired may be. obtained; alsomeans are provided for taking up any shrinkage between the clam and the lifter rod block, all as more fully hereinafter described and particularly pointed out in the claims.

In the drawings-Figure 1 isa perspective View of a striking pneumatic as used in automatic musical instruments showing at the end thereof my improved connection, Fig. 2;-

is a side elevation thereof showing the clamp and striker rod block in vertical central'sec tion. I

A represents. the stationary board of a striking pneumatic, such as is ordinarily employed in automatic musical. instruments, B the movable member or board thereof, and C the connecting fabric, the whole being a small bellows. that when controlled by suitable valves this bellows is to be collapsible, such collapsing.

striking the blow which is to soundthe desired note. It is customary to connect to the movable board. of the striking pneumatic a lifter rod such as O; Y e i e My manner of connecting the'vertical rod to the movable board of the pneumaticcom prises a clamp consisting preferably of sheet metal, and comprises a flat plate portion a. which is secured to the movable board and the clamping ortion b. The clampin portion is prefera ly a bifurcated or divide portion, leaving a space .0 between the two por' tions' in the metal, and this is formed by bending the strips of the two furcations into circular form, as plainly shown in the drawings. Withinthe clamp or socket thus formed of the portions 12 I place a crossbar or It is well known in the artblock D, preferably ofleather or some other fibrous material, the portion b beingclamped tightly down upon the same so as to hold it firmly in position. To the block orbar D I pass the end of the lifter rod C, this rod being suitably screw-threaded,'so that it may be adjusted to an desired length. At the upor end of the ifter rod 0 I attach the usual lead E. The furcations b, when they are bent around the block'D, are bent so that the ends thereof preferably are not in contact With the body portion a of the clam so that if the bar D should shrink, and thuslbosen, the

the 0 amp upon the bar. This can be done by any ordinary tool which will squeeze the I parts together. It is obvious from the draw- 'ings that the lifterrod'C passes through the bar D between the furcations b.

' This construction is easily built, and is of novel manufacture, and there is no danger of the parts becoming loosened. The striker rod block I) forms a comparatively long bearin for the screw threads of the rod C so as to he (I both firmly in adjusted position, and

operation of the device.

' What I claim as my invention is 1. The combination of a fibrous block or bar, a lifter rod secured thereto, a clamp embracing the block or bar, and a movable member to which'the clamp is secured.

2. The combination of a fibrous block or bar, a lifter rod secured thereto, a closable clamp embracing the block or bar, and a movable member to which the clamp is secured.

3. The combination of a fibrous block or a bifurcated clam embracing the block or bar on opposite si es of the lifter rod, and a cured.

- 4. The combination of a fibrous ;block, a lifter rod having a screw. threaded engagement therewith near the middle, a bifurcated member to, whichthe clamp is se'ipnred',

In testimony whereof I affix 'in presence of two witnD-sses.-
