The cona supporting-boaring for the sleeve N and struction and arrangement of this mechanism sprocket L. Inasmuch as this bracket is seare as follows: cured to the wall of the casing A, which is F is the motor-shaft, which is preferably made of wood, there is danger of the bea ring arranged parallel to the spindle D and the being thrown out of exact alineinent of the roll C through expansion or shrinking of the wood. I therefore provide a construction in which the parts will be permitted to rotate freely even when the outer bearing is not in exact alinement. To accomplish this, the stubaxle M is terminated a short distance within the end of the sleeve N when in its outermost position.

R is a shaft forming an extension of the axle M and having its outer end journaled in the bearing Q. As the axle M and shaft R both engage with the sleeve N, they will be held in substantial alinement; but sufficient clearance is provided to allow them to assume a slightly-angular position without binding. To hold the shaft R in position, the hearing, such as the spring S, secured to the bracket Q, is arranged to engage with the end of the shaft. This end is preferably tapered to a point to reduce friction on the end of the stub. Axle M is also preferably pointed.

The bearing in the casing A is formed by a comparatively thin plate T of metal, and the aperture in the wood is formed large enough to provide clearance, so as to prevent binding.

In operation the winding-roll C is driven whenever the pins O and P are in engagement, and the rewinding-shaft D is driven to rotate in the opposite direction whenever the pinion H is in engagement with the gear-wheel G. These two couplings must be simultaneously operated, so that the one is disengaged before the engagement of the other, thereby preventing the roll 0 and spindle D from operating against each other. For accomplishing this an operating mechanism is provided, in which U is a lever under the control of the operator. V is a link connecting this lever with an arm W of a rock shaft X, said shaft being vertically arranged near the rear edge of the casing A and preferably journaled in bearings in the bracket'Y. The rock-arm IV preferably extends in a substantially horizontal plane and at its outer end has a downwardly-bent portion W, which is connected to the link V. Z is an arm projecting upward from the arm W, which embraces the sleeve N and engages with the groove (Z therein. c is an arm projecting forward from the upper end of the rock-shaft X and engaging with the groove 0. Thus whenever the rockarm W is operated through the medium of the link V the arm Z will be moved to slide the sleeve N into or out of engagement with the winding-roll C. At the same time the rocking of the shaft X will swing the arm a, so as to slide the pinion H out of or into engagement with the pinion Gr.

It is usual in ,the construction of pianoplayers to provide a regulator for controlling the motor while it is operating the windingroll, which regulator is thrown out of action during the rewinding. With the present construction the regulator (not shown) is controlled in its operation by the actuation of a link f, which is connected to a rock-arm 9, secured to the rock-shaft X. Thus the three rock-arms W, a, and f are all simultaneously actuatedby the operation of the lever U.

WhatI claim as my invention is 1. In combination with the tracker-casing, the winding-roll and rewinding-spindle therein, shiftable gearing instrumentalities for said spindle and roll located wholly without said casing, and a clutch intermediate said instrumentalities and the windingroll disposed within the casing.

2. The combination with the tracker-case and the winding-roll therein, of a rotary driving member without the case in axial alinement with said roll, and a clutch for coupling said roll and drive member, one part of said clutch being carried by the driving member and the other part at the end of the roll.

3. The combination with the tracker-case,

the winding-roll therein and the rewinding' spindle, of a drive-shaft, a rotary member in axial alinement with said roll arranged without said case, a sprocket-and-chain connection between said drive-shaft and driven member, a clutch for coupling said driven member with said roll and instrumentalities operatively associated with said spindle adapted to be engaged with and disengaged from said drive-shaft arranged axially of the roll and within the case.

6. The combination with the winding-roll and the rewinding-spindle, of a rotary driven member in axial alinement with said windingroll, a drive-shaft, a sprocket-and-chain connection between said drive-shaft and rotary member, a gear-wheel on said drive-shaft, a pinion on said spindle, a rock-shaft, a rockarm thereon having an engagement with said pinion, a clutchfor coupling said driven member with said winding-roll, a second rock-arm onsaid rock-shaft having an operating connection with said clutch whereby said clutch and pinion are simultaneously operated to alternately couple said drive-shaft with said winding-roll and spindle.
