oedals and do 7 Having now described the mechanism whereby elevating the pedals automatically closes the door 3', it remains to describe the mechanism by which the door is interconnected with the door 3 to simultaneously close said door also, in fact to cause the simultaneous operation of said doors whether in closing or opening. This mechanism comprises apair of pulleys 20 shown on the upper door-guide and located respectively toward the rear end of the doors 5 and 3* when in closed position. Cords 21 ant. 22 are looped about the pulleys 20 with the free ends of each cord connected one end to each door near its front edge. The shown arrangement of cords and pulleys comprises what amounts toa crossed-belt, made up of v the cords working on pulleys 20, each ply of said belt being connected with oneof the doors 3 and 3 The result of the construction is that moving either door in either direction, opening or closing, creates a'pull in the given direction on the ply of one of the cords, which pull is converted due to the pulley 20 over which said cord passes into a pull in the opposite direction on the other ply of the same cord, which being attached to the opposite door moves said door in the opposite direction from that in which the first named door happens to be moving. Thus opening the door 3 moves 3 in the opposite direction, that is to say, opens it also, similarly closing the door 8 likewise closes 3 The same thing is obviously true if the door 3 is the one which is primarily actuated by the operator, Accordingly when as heretofore explained the handle 15 is operated to elevate the pedals and to simultaneously close the door 3' through the cord 15, it follows that it will at the same time cause the closing of the door 3 Obviously the present improvements are of great convenience to the users of piano iplayers, since it makes it possible to close the pedals and tracker-box doors in one operation, whereas heretofore two independent operations have been necessary? lvloreover both actions are veilected from a handle 15 within convenient reach of the operator and requiring nosteeping.

It may he said hy. way of further explanation that 25 is a'screw-eye projecting from a. suitable support and receiving through it the cord 16, said cord having a button 26 adapted to contact with the screw-eye when the spring 19' takes up on the cord to keep it tautcn the pulley.

Having thus described my in vention, what ll claim is:

1. In an automatic player, the combination of pedals; a pedal-elevating member acting to elevate the pedals by the operation of the member; a sliding tracker-cox door; and cord and pulley means consisting of a pulley-guided cord-connecting the door and the pedal-elevating member and operating to actuate the door in cloning direction from the operation of said pedal-elevating member.

2. In an automatic player, the combination of pedals, pedal operating mechanism comprising a member adapted to he operated to elevate the pedals, tracke -hot; doors having an interconnection from the closing and opening'of either door to correspondingly operate the other door; and a cord and pulleyconnection between one of said doors and the member which elevates the pedals, adapted from the operation of said member to move said door from open to closed position.

3. In an automatic player, the combination of pedals, pedal operating mechanism comprising amember adapted to be operated to elevate the pedals, tracker-box doors having an interconnection adapted from the closing and opening of either door to correspondingly operate the other door; a cord and pulley connection between one of said doors and the member which elevates the pedals, adapted from the operation of said member to move said door from open to closed position; and cord tightening means comprising an elastic connection with said cord, adapted to keep it at all times taut tion of movable parts; ;cord and pulley means consisting of a pulley-guided cord connecting the movable parts to operate one of them from the movement of the othe"; and cord-tighteningmeans consisting of an elastic connection, between the frame of the player and the cord, taking theredf at the pulley. i

In witness whereof, l haygsigned my name to the foregoing specification in' the presence of two subscribing witnesses.
