MACHINE FOR FORMING IMITATION FAIR-STITCHES TO THE EDGES F BOOT AND SHOE SOLES.

SPECIFICATION forming part of Letters Patent No. 234,503, dated November 16, 1880.

Application filed October 6, 1880. (Model) To all whom it may concern:

Be it known that we, BENJAMIN J. TAYMAN and JOSEPH BENNOR, both of Philadelphia, Pennsylvania, have invented an Improvement in Machines for Forming Imitation Fair- Stitches on the Edges of Boot and Shoe Soles, of which the following is a specification.

The, mechanism employed to effect the object in view is illustrated in the annexed draw- IO ings, in which Figures 1, 2, and 3 are respectively front, side, and rear elevations of the same. Figs. 4 and 5 are respectively face and sectional views, on an enlarged scale, of the impressionstitch wheel 2, showing the rounded bevel a for preventing the wheel-teeth from coming in contact with the boot or shoe upper while the impression fair-stitch is being impressed. Figs. 6 and 7 are respectively sectional and top views of a burnishing-head with the said fair-stitching mechanism applied to it.

s and t are two levers, the lever 8 being attached by the screw it to a plate, 17, which maybe attached by screws to the bottom of a burnishing-head, as shown. The lever 8 turns on the screw to as a fulcrum, the limit of its motion being indicated by dotted lines in Fig.2. The lever t is jointed to the lever s by the screw 20, Fig. 3, and the upper extremity of lever t is attached to the handle so of lever s by the link y, Figs. 1 and 3.

The handle 00 is loose on the shank of the lever s, and is capable of an alternating free motion on said shank, and through link y it 3 5 imparts an alternating motion to the lever t, and through it to the wheel 2, for the purpose of throwing this wheel on and off its work.

2 is an imitation-stitch wheel, such as is usually operated by hand, except that this 0 wheel 2 is constructed with a rounded bevel, a Fig. 5, on the side which in the operation of the machine comes next the upper of the boot or shoe.

The wheel 2 is attached to the lower end of 5 the lever tand arranged at such an angle with relation to the upright roller b Figs. 1 and 6, that the faces of the wheel-teeth shall be parallel with the axis of the roller 11 A spiral spring, (not shown,) one end of it being attached to the lever s and the other end caused to press against the top end of lever it, may be employed, if desired, to throw the lever t out automatically, leaving it to the operator to produce only the opposite motion.

0 Figs. 1 and 6, is a gage, adjustable by means of the screw 0?. The office of this gage is to regulate the breadth of the marginal space-that is to say, the distance between the line of imitation-stitches and the edge of the,soleand cause said space to correspond with the impression produced by the lip of the burnishing-iron on the edge of the boot or shoe sole, thus permitting the part of the soleedge which is not impressed with the fairstitch to be burnished.

In using the fair-stitching mechanism in connection with the burnishing-head the operator, grasping with his right hand the handle m and with his left hand the handle 00, throws the impression-wheel 2 back from the roller 0 by turning the handle as. He then inserts the edge of the sole between the impression-wheel z and the roller b resting said edge on the gage 0 He then clamps the wheel and roller together against the sole by turning back the handle as. The shoe is then moved forward by jack mechanism, (not shown,) the operator keeping the sole clamped and guiding the wheel so as to make it conform to the varying curves and bevels of the sole-edge, at the same time oscillating the handle 00 back and forth on the pivot a, as may be required to keep the wheel z in line with its work.

The fair-stitching mechanism maybe fastened to a bench or table and used apart from the burnishing-head.

We claim 1. The impression-wheel z, constructed with 90 the rounded bevel a for producing imitation angle with respect to the roller 1), in combinafair-stitches Without injury to the boot or shoe tion with the adjustable gage 0 and the roller upper, substantially as set forth. W, for producing imitation fainstitches, sub- 2. The combination of the levers s and t, stantially as set "forth. 5 the alternating handle as, and the link-'oint y with the impression-wheel z, the roller 6 and the gage 0 for throwing the wheel 2 off and on its work and producing imitation fair- Witnesses: stitches, substantially as set forth. THos. A. Emma, 10 3. The beveled impression-wheel 2, set at an JOHN A. YVIEDERSHEIM.
