To all whom imag/*concern Be it known that we,cBriNJaiirrNi HL- Jur:

PERSON and lVALTnn I; Kimi, citizens ofthe United States, residing at Chicago, in the county of look and State oflllinois, have invented a certain newand useful Improvement in Piano-liedalsy andl like Devices, of which the following isa full,l clear, concise, and exact description, reference beingfhad to the accompanying drawings,.forming a part of thisspecication; Y f

Our invention relates to piano pedals and like devices. Y f

One of the objects of the invention is to provideI a practical and effective*form4 of piano pedal or like device.V f Another object of the invention' is to provide a construction of piano pedal'which may be used by an adulty person `or by a child or other person with Vshort legs.

Another object of the invention yis to secure such an vadvantageous Vconstru'ction without substantial or undesirable variation from the usual shape of piano pedal now in use. Y Another obj ect ofthe invention is to give ample foothold or space for pressing or acting upon the` pedal when employed for either purpose. 'n s y Another object ofthe invention is toaccomplish the foregoingjandv other desirable results ina simple and expeditiousmanner.

In the accompanyingdrawingsFigure -1 is a front view of the lower part of a piano provided with three pedals embodying our present invention; Y Y j i Y Fig. 2 is a cross secti n taken on linev 2-2 inFig; f' Fig. 3 is a view ofthe under side of the Pegel; Y,y Y

Fig'.- 5 is a cross section in Fig. 4l. n

Referring to the drawings, vfe'show)4 in Figs. 1, 2 and 3 a portion lof the front of a piano case.4V rlhere rare also shown-three pedals 2, 3 and t, whichl are customarily present in a piano. Y c v VIn 1 two of the pedals 3 and-(l are shown in the conditionl or adjustmentl in which they may beused by the average adult person, which condition or adjustment will be called the normal`conditien or adjust` ment. The other pedal 2 is shown iii-condi# saecieauonpf Letters rate-'na l taken on line 5-55 Patented sept.v 21, 1920.

tion or adjustment to permit of itsl being used by a child or other short legged per? son, it being' seen that while the pedals 3 and have surfaces 3? and 4a, respectively, whichma'y beiactedor pressed upon by the foot, the pedal 2 has a surface Qa'which is substantially above,y the'surfaces 3@ and 4 and therefore capable of being reached4 by? a; child orl other person whose legs vwould not extend downfarenough to reach surfagesy as far downy as surfaces 3a and 4a.

Referring more particularly to the construction of the pedal, we. employa pedal bar 5 -whichp'asses through v*an aperture 6 in the pianolc'ase 1 this bar 5 being understood to be connected'inside the'piano with suitable*'instrunientalities which are operated byv theV depressionfof the bar 5. gflhisA bar .lextends forwardly from the front of the piano case l, terminating in an end por- .tion 5a onvwh'ich the pedal properis mounte'd. Thisppedal Slis composed of two portions, a portion f1' which may be called the mainor body portioinand another portion 8, which may be called-the supplemental' portion and which is at the rear end of portion 'Zand extends upwardly at substantially right'angles to the same. The main or body portion 7 is made hollow so that it vmay-lit down over vthe end portion 5? yof the pedal' bar 5 andthe Vfrontend o-f this portion is pivoted tothey frontend of the pedal bar 5a by-'meansgof a pivot or pin 9.l Because of this pivotal mounting the pedal 3 may be tilted for swung upwardly vand forwardly from' the vnormal position shown4 in solid lines in'lig. 2 to an elevated position shown in dotted lines in saidFig. 2. `In the former position,` the pedal may be'jused in theusual way by resting-the foot upon the surface 37, whereas in the other or adjusted position the` foot will rest upon the surface 8a' which is substantially above the surface 3a when the pedal is lowered. V

ff The pedal bar 5 is provided with a layer l0 of felt orv other cushioning material which l is conveniently wrapped around the rear part of the lend portion 5u.I This permits the pedal member 3io be moved `or dropped 'down into lowered position without making a noise oi" doing, anyY injury, 'the body portion V 'of said pedal 3 coming* in Contact with the felt or cushion material 10. i

lAs a matter of further improvement a stop 1l is provided `forlimiting the upward and forward adjustment of the pedal, said stop 11 being conveniently secured to the pedal bar end 5et and located so that the front end portion of the pedal will strike against said stop 11 when the pedal is tilted .or swung into its upper position.

As an arrangement for temporarily holding or locking the pedal 3 in either upper or lower position, we show a ball 13 carried by the pedal bar end 5, and two apertures 15 and 16 in a plate 17 on the pedal 3, so thaty the movement of the pedal will locate the ba'll 13 on one or the other of the apertures 15 and 16 and thereby lock it in such position. The aperture 16 is so located that when the ball 13. is in position in it, the pedal will be in an elevated position, as shown in Fig. 4:. The aperture 15 is so located that when the ball 13 is in position in it said pedal will be in a downward position, as indicated in dotted lines in Fig. 4c. in order to permit Vthis operation, a plate 19 is secured as by screws 20 to the pedal bar end 5l and is bent laterally at 21 and then again to form a straight portion- 22 substantially parallel with the end 5a. This end portion 22 is provided with the aperture 14 containing the ball 13. Between the end portion 22 and the end 5a is located a spring 23 which tends to hold said members 22 and frL in a separated positionv and to resist movement of the same toward one another. Thus' when the ball 13 is located in either of the` apertures 15l or 16 the pedal 3 and pedal bar 5 are held in the position to which they are adjusted with a substantial amount of strength, but this may be overcome and a. movement of the pedal 3 accomplished to "change its adjustment by a quick and strongv effort, sufficient to cause the ball 13 to move out of one of the recesses 15 or 16, and overcome the resist-ance of the spring 23 and thus move to the other of said"` recesses; Upon arriving at such recess the ball 13 is snapped into such recess by the power of the plate 19 and spring 23, and held in the same with substantial strength, sufficient to permit the proper use of the pedal. Adjustment back to the original position, however, may be obtained by a quick and strong movement of the pedal, sufficient to withdraw the ball 13 from the aperture in which it is located, overcoming the tension of the spring 23 and member 19. As a preferred arrangement the pin 9 is in the form of a threaded spindle which can be screwed into a threaded socket formed in the kend portion 3c of said pedal.

In this way it willv be seen that the pedal itself may be used in the ordinary way' or may be adjusted so as to provide an elevated pressing surface to' permit use by short legged persons. It will also be seen that no outside device or apparatus is required to accomplish this result, the pedal itself being sired end.

It will be understood that changes and modifications may be made without departing from the spirit of the invention.
