PLAYER-GRAND PEDAL-ACTION.

Patented Oct. 12, 1909.

To all whom it may concern:

Be it known that we, Jns'rns HATTEMER and ARTHUR Konin, citizens of the United States, residing at lest New York, in the county of Hudson und State of New Jersey, have invented certain new and useful Improveniente in Player-Grand Pedal-Actions; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which .it npperteins to niako'and use thesame.

This invention relates to pedal notions for player grund pianos, and has for en object to provide e )edel n'iechanism ada ted to be mounted within a l-yre disposed eneath a. grand piano in substantially theusual manner. A further object of the invention is to pro- Yvide an improved form of lyre adapted to contain pedals when folded and to present, when closed, the usual pedals found in the lyre of e grand piano.

lVith these and other objects in View, the invention comprises certain novel constructions, combinations and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings :#Fidgure 1 is zt View of the pedal mechanism in side. elevation with the` side of the lyre removed, showing the edel shown. in full lines und folded within the lyre in dotted lines. Fig 2 is e View of the lyre in front elevation with the closure opened and also showing the pedals in front elevation opened.

Like characters of reference designate corresponding parts throughout the several views.

The body of e grand inno is shown conventionall at 10 depen( ing beneath which nre the si e wlls 11 and 12 of the lyre being formed in any approved manner, and with the rear side closed by n back 13, :ind the front closed by a front 14 having e lower section or door 15, hinged at 16. Upon the base 17 a frame 18 is hinged having feet 19 carried rigidly therewith adaptedy tol rest' upon the floor when the traine 1S is in ppened posltlon, as shown 1n full lines in Hg. 1.

4Upon the frame 18 pedals 20 and 21 are pivoted as by the hinges 22 and 23, respectively. "Within the lyre box levers 24 and 25 are respectively pivoted, as :it QG and Q7, und also respectively connected by ii-.enns of links 28 and :29 with the pedals 2() and "21A At any approved or convenient. position within the piano body, bellows 30 are mounted, preferably in pairs, und from such bellows links 31 and depend downwardly through the bottom of the body and are, respectively, connected with bell crank levers 38 sind 34. The bell crank levers 33 and 34 are, respectively, connected by means of A links 35 and 36 with the levers 24 and 25.

It will be seen from. Fig. 1 that the frame 18 and the pedals 20 and 21 pivoted thereon are capable of being folded upon the hinge 3T within the lyre box to the position shown in dotted lines, and that when so closed the cover 15 may be closed downwardly upon its hinge to close the front of such lyre box, leaving only the pedals 38 extending outwardly therefrom connected with the'usual pedal rods 39.

It will be apparent that with the lyre box; given a fanciful design, itwill be scarcely noticeable from the lyres ordinarily employed beneath grand pianos and upon which the ordinary pedals are fulcrumed,

nected with the pedals, bellows positioned to actuele pneumatic mechanism, levers mounted to operate the bellows, and llnks connectin the first-mentioned levers with In testimony whereof we a our sigthe secon -mgntioned leviers. f d l natures 1n presence of two witnesses.
