FINISHING-MACHINE FOR THE USE OF SHOE-COBBLERS.

Specification of Letters Patent.

Patented Nov.. 13, 1906.

Application filed December 9,1905. Serial No. 291,103.

ishing-Machines for the Use of Shoe-Cobblers, of which the following is a specification.

My improvement relates to that class of machines used by cobblers or shoe-repairers.

for finishing rep air-work.

The object of my invention is to provide a cheap, light, compact, and portable machine to be operated by foot-power, adapted to carry several cutting and polishing wheels, which can be easily adjusted and changed.

The manner in which I accomplish my ob ject is described in the following specification and illustrated in the accompanying drawings.

Figure 1 is a front elevation of the machine; Fig. 2, side view.

The frame A, forming the main body of the machine, is constructed of one piece. The lower rear part of this frame is adapted to contain a set of bearingboxes B. J ournaled in these boxes is a driving-shaft C, adapted to support a driving-wheel D. On each end of this shaft a disk E is attached. Each of these disks is provided with an adjustable crank-pin F. Pivotally attached to each of these pins is a connecting-rod G. The lower end of each of these rods is pierced with a number of holes H, arranged in a vertical line. Pivotally connected with the lower end of each of these rods is a horizontal lever I. These levers are pivotally connected with the rear legs of the frame A and are connected with a cross-bar J at the front of the frame, thereby forming a treadle. Each of the levers are pierced with a number of holes K and L, arranged in a horizontal line. These holes, in connection with the holes in the connecting-rods, permit of the adjustment of the treadle both vertically and horizontally.

The upper part of the frame A is inclined forward, as shown in Fig. 2, and is adapted at the upper end to support a set of bearingboxes M. These boxes are adapted to slide vertically in the frame and to support a spindle N. This spindle is provided with a pulley O, adapted to be connected by a belt or chain P with the driving-wheel and with adjustable collars Q, adapted to form bearings against the boxes M. Supported on this spindle are several grinding and polishing wheels R, separated by sleeves S, which are of various lengths and adapted to slip on and off the spindle and which, together With the wheels R, are secured on the spindle by the nuts T on the threaded ends of the spindle. Beneath the boxes M and pivotally attached to the frame H are two eccentric levers a, which are adapted to support the boxes M in the position required when the machine is being operated and to lower them and the spindle so the belt or chain can be removed from the driving-wheel and the spindle be removed from the frame altogether. The pivot-studs v, on which these levers are supported, are adjustable vertically in the slots indicated by the dotted lines, and thereby permit the adjustment of the spindle, so as to secure the desired tension of the belt or chain connecting the spindle with the driving-wheel. The stop-pin w is adapted to engage and hold the levers u in position.

What I claim, and desire to secure by Letters Patent, is

1. In a machine of the kind described the combination consisting of a frame A, the lower part of said frame being adapted to support a pair of bearing-boxes, a pair of bearing-boxes B supported in the lower part of'said frame, a shaft C supported in said bearings and said frame adapted to be revolved therein; a driving-wheel D supported on said shaft adapted to be engaged by a belt or chain; a pair of disks E attached to said shaft, one at each end; a crank-pin F adjustable, secured in each of said disks; 2. pair of connecting-rods G pivotally attached to said crank-pins, each of said rods being pierced with a series of holes H arranged in a vertical line; a pair of horizontal levers I, pivotally attached to the rear legs of the frame, and to said connecting-rods, each of said levers being pierced with series of holes K and L, said levers being connected together by a crossbar J; a pair of bearing-boxes M supported in the upper end of the frame A and adapted to be adjusted vertically therein; a spindle N supported in said boxes; a pair of collars Q adapted to hold said shaft in position in said boxes; a pulley 0 attached on said spindle adapted to support a belt or chain; a belt or chain P attached to and connecting said pulley with said driving-wheel; a pair of eccentrio levers u pivotally supported on said frame adapted to be moved and to support and adjust said bearing-boxes and said spindle and thereby adjust the tension of the belt or chain P; a pair of adjustable pivot-studs v adjustably secured in said frame, adapted to support and to adjust the position of said eccentric levers; a pair of stops w afIiXed in said frame, adapted to hold said eccentric levers in position; a plurality of sleeves S, adapted to slide freely over said, spindle; and suitable Wheels for grinding and polishing adapted to be supported on said spindle; substantially as described and for the purposes specified.

2. In a machine of the kind described the combination consisting of a frame A; a pair of bearing-boxes B, supported in the lower part of said frame; a shaft C supported in said bearingboxes; a Wheel D supported on said shaft; a pair of cranks E attached to said shaft; a pair of connecting-rods G attached to saidcranks, having a series ofholes H arranged in a vertical line; a pair of levers I pivotally attached to the rear legs --of said frame and to said connecting-rods and havboxes M supported in the upper part of said ing a series of holes K and L and being connected together by a bar J; a-pair of bearingframe; a spindle N sup orted in said boxes and provided With a pul ey O and adapted to support grinding and polishing Wheels R; a 1

supported on said shaft; a pair of cranks E 7 attached to said shaft; a pair of connectingrods G attached to said cranks; a pairof le vers I having a cross-bar J; said levers being pivotally attached to said frame and to said connecting-rods; a pair of bearing-boxes M' supported 1n said frame so as to be moved vertically therein; a spindle N supported in said boxes ada ted to support one or more polishing-whee s Rand having a pulley O a belt P connecting said pulley and said Wheel, and a pair of eccentric levers supported on said frame, adapted to support and move said boxes and spindle vertically in said frame, substantially as described and forthe purposes specified.
