PATENT oFFroE.
THOMAS E. DQUGHEBTY, OF CHICAGO, ILLINOIS SELF-PLAYIN'QMIISYICAL INSTRUMENT.
Specification of Letters Patent.
Patented Aug. 3, '1909.
Application filed July s, 1908, Serial No. 442,009. Renewed June 23, 1909'. Serial No. aca'ssa' a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Self-Playing Musical specification.
Instruments, of which the following is a The object of my invention is to provide an improvement in a detail of self-playing musical instruments such as pneumat1e piano players.
More specifically my object is to provide an improved adjustable connection between the pneumatics and the piano or organ action.
These objects and others will be made a parent in the following specification and c aims, when taken in connection with the accompanying drawings, in which--- Figure l is a side elevation of my improved mechanism and Fig.2 is a front elevation of a plurality of the usual abstracts showing my improvement ap lied thereto. I
The usual manna playing key is pivoted at 16 and the screw 17 at the'end thereof strikes against the vertical abstract or sticker rod 18, which actuates the usual wippen 19 at its top end and through it the hammer 20 and the other parts of the iano action.- The abstracts 18 are arranged in a row extending across the piano and thus they occupy a vertical plane running across the piano. On'the front face of each' abstract there is attached an upper guiding sleeve 21 by means of a screw 22 and a lower internally screw-threaded uiding sleeve 23 by means of a screw 24. T rough these two guides 21 and 23 extends a rod 25, the portion thereofwhich extends through the lower screw-threaded block 23 being screwthreaded as indicated by the reference numeral 26, soas to engage therewith. The upper endof the rod 25 is flattened on the sides, as indicated by the reference numeral 27 sothat it can readily be engaged by a wrench or pliers. The lower end of the rod 25 carries a block 28 having a felt 29 on its lower surface. This is engaged by the forwardly projecting arm 30, which is attached to the under member 31 of the pnemuatic 32. The upper member 33 of this pneun'latic is rigidly attached to the transverse frame member 34. Inasmuch .as it is desir-able to make the pneumatics wider stract 18, they are arranged, superposed staggered horizontal rows, the intermediate and uppermost pneumatics being indicated by dotted lines in Fig. 1. The rods 25 are made of different lengths, as shown in Fig. 2
so as to bring the blocks 28 at different I heights corresponding to the different rows of pneumatics.
The proper adjustment between the keys 15 and the abstracts 18 having been made, it is desirable to adjust the connectionbetween the pneumatics. and the abstracts correspondingly. .It is obvious that this canbe done by rotating the rod 25 so as to screw it up or down in the guide 23. This can readily be done by engaging thetop end 27 which reaches up above the pneumatics and is therefore easily accessible. It can either be engaged by a wrench or pliers or even by the fingers of the operator. Thus the height of the block 28, which is the part engaged by the member on the pneumatic, can be changed relatively to the abstract 18.
