To @ZZ 'whom ma/,y concern.'

l,13e it known that I, WILLIAM C. BosEN- BURY, a citizen of theuUnited States, residing at Richmond, in the county f'Wayne and State of Indiana, have invented new'and useful Improvements in Mechanism for Operating Mufflers on Musical Instruments,of which the following is a specification.

thereof.

which will ap-pear from the mechanism illus` My invention relates to improvements in mechanism for operating muftlers on musical instruments to be operated by the hand of the operator; and the objects of myimprovements are, first, to` provide a simple and positive mechanism toA be controlled by the hand of the operator and for the purpose of operating the muiilers on pianos; second, to provide a device of the class stated with newand novel features which are herein shown and which can be easily controlled bythe person using the musicalinstrum'ent, and, third, to provide a new article of manufacture, a device for operating and controlling the muilers of musical instruments, which will add to the efticiency and appearance of the musicalinstruvment without materially increasing the cost I attain these and otherv objects trated in the accompanying drawings, forming a part of this specification, in Whiche- Figure 1 is a perspective view of the inside surface of one of the outside Walls of a piano, showing my invention in perspective and by means of. dotted lines the two positions my mechanism is intended to'assume. Fig. 2 is a 'sectional detail view of a portion of my f mechanism greatly enlarged. Fig. 3 is a front view of the parts of my mechanism show n in Fig. 2 and on the same scale as Fig. 2. Fig.

4 is a detail cross-section of the parts shown in Fig. 5,taken from the rear on line XX of Fig. 1. Fig. 5 is .a detail sectional view of 'the parts shown in Fig 4,- taken on the line T T Of Fig: 4.

Similar figures and letters of reference refer to similar parts throughout the several views. Refering now to the drawings, the parts rcferredto by .figures are the parts which I claim as new, and the parts referred to by letters are old and are shown in order to show with reference thereto.`

A represents the muiiier-ba'r which my inas shown by the dottedlines.

B represents the block placed between the outer Walls of the piano'and the piano-keys.

C represents the outer wall of a piano.

D represents the music-shelf of a piano.

E represents the keys of a piano.

F represents the music-desk of a piano.

2l represents an arm' extending backward and upward from the side of the keys E and pivotally connected to thearm 22.

22 represents an arm pivotally secured to the side of the piano and also to 21 and 23.

23 represents an'arm extending up from 22v and connected near the center of the arm 24;.

24 represents an arm pivotally connected to the side of the piano and to the upper end of 23.

25 represents a spring-clamp for holding 24 in contact with the pivotl 3l and .the side of the piano.

26 represents a spring-clamp for holding 24 in contact with 23 and the pivot 30.

29 represents a'rivet securing 26 to 23.

30 represents a rivet passing through 26, 24, and 23. y

31 representsa rivet or pin uniting 24and 25.

32 representsa screw by -which 25 is secured lto the piano.

33 represents a and 22. o

-34 represents a pin or rivet connecting 2l and 22.

35 represents a screw by which the end of 22 is fastened to the piano.

36 and 37 represent wooden pins or pegs secured in t-he piano and act as stops for my mechanism.

38 represents a plate with a longitudinal slot secured to the block B, as shown.

40 represent-s a knob attached to 21 and extending up through the slot in 38 for the purpose of forming a hold by which my mechanv ism can be operated by hand.

The operation of my mechanism 'is accomplished by moving the knob .t0-backward and forward, as shown by the dotted lines, to operate the muier.

Thus it canbe seen,

IOO

that when the knob 40 is slid tothe frontxbf-'w the slot in the plate ,33,- as shownabynthe solid lines in Fig. 1, my mechanism will assume the position shown by the solid lines throughout the view. Desir-ing now to raise the m-nierA, the knob 40 is pushed to the rear in said slot, when the mechanism and the muiiier will assume the position shown by the vdot-ted lines in Fig. 1, whereupon the arm 22 will abut the stop 36, and the pivot 33 will be on a Hdeadcenter,which insures the retention of the parts in position without the 'aid of a locking device until the knot 40 is pulled to original position.

My improvements are herein shown as aplied to the inside left-hand end of a piano. It is apparent that they are equally applicable for attachment on the opposite end of a piano,

if so desired.

From the foregoing description, taken in connection-with the drawings, the operation Yas Yof this invention will Vbe readily understood and its many advantages be fully apprecir ated, and I will simply state'that the device herein shown by reason of its simplicity, attractiveness, ease and eiciency of operation will provea iiseful and practical invention, as I have fully demonstrated.

- My improvements are perfectly adapted to accomplish the results for which. theyare intended; but it is evident that changes in and modifications of the construction herein Shown and describedV may be made and that analogous parts may be used to accomplish"- sides of the second pivoted arm and limiting y,

the movementof. said arm, a connecting-arm extending between said arms 'and pivotally connected te both of them, a substantially horizontally movable arm pivoted 'to the arm playing between the stops, and a handle for the horizontal arm, one of said stop-pins being adapted to arrest the play of the second necting-arm-pivoted to the aforesaid arm intermediate the length thereof, separate stoppins, a lever having one end pivoted to the piano and its other end pivoted to the end of the connecting-arm, and adapted to play between the stop-pins, a substantially horizontally movable arm pivoted to the lever intermediate the ends thereof, and a handle for the horizontal arm, one of said stop-pins being adapted to arrest the play ofthe lever to cause its pivotal connection with the connecting-arm to lie on a dead-center and hold the m'ufiier-bar in operative position.

3. In a mechanism for operating |nuilier bars for pianos, the combination with a mut'- tler-bar, of an arm connected to the multicrbar` and being itself pivoted, a connectingarm, a spring plate or clamp having one end secured to` the connecting-arm and its other end free to spring toward and away there from, said mutiier-operating arm being located between the spring-clamp and the operating-arm and having a pin whose ends' project into apertures in the spring and connect` ing-arm.

In testimony whereof I have signed my nameto this specification in the ypresence of two subscribing witnesses.
