IMPROVEMENT IN MACHINES FOR TRIMMING SOLES 0F BOOTS AND SHOES.

# Specification forming part of Letters Patent No. 136,790, dated March 11, 1873.

To all whom it may concern:

Be it known that I, BENJAMIN J. TAYMAN, of the city of Philadelphia and'State of Pennsylvania, have invented certain Improvements in Machines for Trimming Shoe Soles and VVelts and'Burnishing the Soles, of which the following is a specificationr adjustment.

The peculiar construction of the machine is hereinafter fully described.

Figure 1 is a plan view of the machine. Fig. 2 is a side elevation'of the same. Fig. 3 is an end elevation, in which ashoe is seen in position for the trimming of the sole and welt. Figs. 4 and 5 are top and edge views of the rest P.

' Figs. 6, 7, and 8 are top, side, and edge views of the guide 0. Figs. 9 and 10 are top and edge views of the finger-support of Q. Fig. 11, Sheet No. 2, is a side view of the shaft E, having on one end, cutters F and F for trimming the edge of the sole, a cutter, F for trimming the welt, and a circular guide, N; and on the other end a burnisher, H, and a guide, N, on an enlarged scale. Fig. 12 is a cross-section of the shaft E at the dotted line a b of Fig. 11. Figs. 13 and 14 are edge and face views of the ghide N. I

Like letters in all the figures indicate the same parts.

Ais the bed-plate, which has an upright, B, at its front end provided with a slot, at, in which the square part b of .the swivel O is supported. The swivel C is connected to the swivel G by means of the rod D, which has a screw connection with the heads, so as to admit of their turning freely thereon. The swivel G is provided with a revolving shaft, E, carrying circular cutters F and F for trimming the edge of the sole, and a like cutter, F for trimming the welt on oneend, and acircular burnisher, H, and guide N on the other end. The front edges of the teeth 25 of the cutters F and F have aforward inclination toward the outer faces of the cutters for the purpose of the cutters.

bined action of both cutters, thus preventing v the formation of a feather-edge on the outer corner of the sole. The outer cutter F is sufficien tly thick to project over the thickest sole, and thus secure a clean cut. The'swivel G is provided with a revolving shaft, E, whose journals are supported by the forked upright B. On the shaft is a double pulley, I, with which is connected the band J, which connects also with the driving grooved wheel K and the pulley L on the shaft E for revolving the cutters F, F, and F and burnisher H. The

upright B is adjusted so as to elevate or depress the swivelG by means of a vertical slot, 2, in the bed-plate, and the tightening-screw M. N is a circular guide on the shaft E. It turns loosely on the shaft so as to roll in the depression 0 formed by the junction of the sole and upper of the shoe, as seen in Fig. 3, to prevent friction and consequent injury to the leather. N is a loose guide in combination with the burnisher H. In connection with said guide N there is a gage, O, seen in detail in Figs. 6, 7, and 8, which presses lightly upon the upper to assist in keeping the shoe in its normal position while the sole is being trimmed and to prevent said guide N cutting the stitches. It is connected with the stationary plate 0, the inner end of which is secured to the swivel G. The guide has a vertical adjustment by means of the connection of the shank d with the groove 6 in the front end of the plate 0. P is a rest, shown in detail in Figs. 4 and 5, which is fastened by means of a screw to the swivel C. The object of this rest is to prevent the cutter F throwing the shoe out of its proper position when short curves of the sole are brought against Q is a finger-support, seen in detail in Figs. 9 and 10, which is secured to the swivel C by means of screws g g. It has on its front end a curved projection, h, on which the operator places a finger to steady his hand in holding the shoe and changing its position.

Operation.

The shoe is held up against the guides N and O and rest 1? by the operator, and turned around to bring the continuous edge of the sole against the. cutters F and F as they revolve in the direction of the arrows by means of the band J, driving-wheel K, and pulleys I and L, whereby the edge of the sole is trimmed, the welt being trimmed at the same time by means of the cutter F When the edge of the sole is to be burnished the square part I) of the swivel (J is raised out of its seat a, and the head is turned one-fourth round, so as to bring the shaft E vertical and with the burnisher H on its upper end. The part b is then con nected with the seat a for holding the shaft securely in position. The changing of the shaft from one position to the other may be made while it is running.

By removing the devices for trimming and burnishing shoe-soles the machine may be used for dovetailing and like purposes by the connection of suitable cutters with the shaft E.

I claim as my invention- 1. In combination with the revolving shaft E, the cutters F and F having the front edges of their teeth t inclined forward to the outer faces of the cutters to produce drawing cuts toward the middle of the edge of the sole, substantially as and for the purpose described.

2. The cutter F in combination with the cutters F F substantially as specified.

3. The gage O, in combination with the cutter F and loose guide N, substantially as and for the purpose set forth.

4. The rest P arranged and operating in relation to the cutters F, F, and F substantially as and for the purpose specified.
