FRANK RENEK, OF NEW YORK, N. Y.

PIANO-CASING.

Application filed January 31, 1911.

To all whom it may concern Be it known that I, FRANK IlnNEn, a citizen of the United States, and a resident of the city of New York, Astoria, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Piano-Casing, of which the following is a full, clear, and exact description.

The invention relates to player pianos and similar musical instruments, and its object is to provide a new and improved piano casing having a mechanism for opening and closing the panel and for moving the pedals for the bellows into an active or a folded position, on the operator opening or closing the casing for the controlling mechanism of the player piano.

The invention consists of novel features and parts and combinations of the same, which will be more fully described herein after and pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a front elevation of the piano casing showing the controlling levers covered, the panel closed and the pedals for the bellows in folded position; Fig. 2 is a like view of the same and showing the controlling levers uncovered, the panel open for the insertion or removal of the music roll, and the pedals of the bellows in position for use; Fig. 3 is an enlarged sectional rear face view of the same, on the line 33 of Fig. 4; Fig. l is a cross section of the same on the line 4-4 of Fig. 3; and Fig. 5 is a plan view of the cam slide.

The piano casing A of a player piano or similar instrument, is provided at the keyboard B with a covering C for covering and uncovering the various controlling devices D on the player piano, and the said piano casing A is also provided at the front upper portion with an opening E for gaining access to the music roll F (see Fig. 2) to permit of removing the same from the casing and replacing the same by another music roll, and the said opening E is controlled by a panel made in sections G, G, mounted to slide toward and from each other to close or open the opening E. The piano casing A is further provided at its front lower portion with an opening II, adapted to be closed by a pedal board I, carrying the Specification of Letters Patent.

pedals I, connected by links I with the bellows of the player piano. The pedal-carrying board I is pivotally connected by hinges I with the bottom of the piano casing, so as to permit of swinging the board I downwardly and for 'ardly into open position to permit of actuating the pedals I, or the said board I can be swung upward into vertical position for closing the opening H.

The panel sections G, G and the pedal board I. are controlled from the covering C, in such a manner that when the covering C is swung by the operator into a closed position, as shown in Figs. 1 and l, then the panel sections G and G are moved into a closed position and the pedal-carrying board I is swung upward into a closed position.

lVhen the covering C is swung into an open position by the operator, then the panel sections G and G are moved into an open position, as shown in Fig. 2, and the pedal-carrying board I is swung forwardly and clownwardly to permit the operator to actuate the pedals I.

The covering C is connected at its front lower edges by hinges C with the bottom of the keyboard B, and one end of the said covering C is pivotally connected by a transversely-extending link J with a cam slide K mounted to slide on the bottom of the keyboard B and also in guideways K attached to the corresponding side of the piano casing A (see Figs. 3 and 4). The slide K is provided with a sidewise-extending arm K having an inclined slot I (see Fig. engaged by the lower end of a lever Ii, fulcrumed at L to the piano casing, and the upper end of the said lever L is provided with a pin L engaging the forked lower end N of a lever N, fulcrumed at N on the front of the piano casing A, and the upper end of this lever N is pivotally connected by a link 0 with a vert-ically-disposed lever 1 fulcrumed at P on the front of the piano casing A. The ends of the lever I are pivotally connected by links P P with arms G G held on the back of the panel sections G, G, mounted to slide in guideways G arranged on the rear face of the front of the piano casing A- hen the several parts are in the position shown in Figs. 3 and t, then the covering C and the panel sections G, G are in closed positions, and when the operator swings the covering C forwardly and downwardly, then the link J imparts a forward sliding motion to the slide K, which by the slot 1 imparts a swinging motion to the lever L, the motion of which is transmitted to the lever N, and the latter by the link 0 imparts a swinging motion to the lever P, which by the links P and G out- P moves the panel sections G wardly away from each other, so that the panel sections G, G move into the open position shown in Fig. 2.

lVhen the covering C is swung upward and rearward into a closed position to cover up the controlling devices D then a rearward sliding motion is given to the slide K by the link J, and the motion of the slide K is transmitted by the mechanism described to the panel sections G and G, to move the same into a closed position.

The rear end of the slide K is provided with a depending arm K pivotally con nected by a link Q with an arm 0, ful crumed on a bracket Q? attached to the rear end of the bottom of the keyboard B, and the said arm Q is pivotally connected by a link with an arm R of a bell crank lever B journaled in brackets S attached to the bottom of the piano casing A. The bottom R of the bell crank lever R slidingly engages a bearing I attached to the pedal board I. Now when the several parts are in the position shown in Figs. 3 and t, then the covering C is in a closed position and the pedal board I is folded into vertical position against a stop T held on the casing A. hen the operator swings the covering C forwardly and downwardly, as previously mentioned, then a rearward sliding motion is given to the slide K by the link J, and the slide K now imparts a swinging motion to the arm Q by the link Q, and the arm Q imparts a rocking motion to the bell crank lever It by the link Q and the bell crank le ver R swings the pedal board I forwardly so that the pedal board I and the pedals I move into an extended position for use by the operator. lVhen the covering C is swung upwardly and rearwardly into a closed position then the movement of the parts just mentioned is reversed, that is, the bell crank lever it swings the pedal board I into a folded position against the stop T.

From the foregoing it will be seen that when the operator imparts a swinging motion to the covering C, a simultaneous motion is given to the panel sections G and G and the pedal-carrying board I, that is, when the covering G is swung into a closed position the panel sections G and G are likewise moved into a closed position, and the pedal-carrying board I is moved into a folded position, and when the covering C is swung into an open position then the sec tions G and G are opened and the pedalcarrying board I is swung downward into active position.

Having thus described my invention, 1
