SI-IOE-EDGING MACHINE.

Specification of Letters Patent. Patented Sqgpt, 19, 1916,

Application filed May 27, 1916. Serial No. 100,340.

To all whom it may concern:

Be it known that we, JOSEPH E. PER- nun/r and HOWARD G. Ennis, citizens of the United States, residing at Belmont and \Vatertown, Massachusetts, have invented certain new and useful Improvements in Shoe-Edging Machines, of which the following is a specification.

Our present invention relates to improvements in apparatus designed more especially for applying to footwear out soles of unvulcanized rubber which are subsequently to be secured thereto by vulcanization and the object of the invention is to provide a ma chine by which the soles may be easily and rapidly applied with the minimum amount of labor on the part of the operator.

The invention includes the novel features of construction and arrangement and com bination of parts hereinafter described and particularly defined in the appended clalms.

An embodiment of the invention is illustrated in the accompanying drawing, in which,

Figure l is a side elevation of such a machine or apparatus, and Fig. 2 is a front view.

Heretofore it has been customary for the operator to apply these unvulcanized soles by having the last carrying the shoe mounted upon a stationary support and rolling the rubbersole down by hand by a suitable roller and thereafter turning the edge of the sole over the lower edge of the upper and rolling it down by a roller held in the hand but it has been unsatisfactory and tedious to manipulate by hand the last carrying the shoe and also the rollers.

Referring by reference characters to the drawing the numeral 1 designates a suitable supporting frame, preferably of bracketform, adapted to be secured to a wall or other suitable support and provided with suitable bearings, in which is journaled a shaft 2 carrying a drive pulley 3. This drive pulley 3 may be driven from any suitable source of power. The shaft 2 is eccentrically connected at one end by means, such as an eccentric pin 2 with the upper end of a pitman 4, the lower forked end P of which is pivotally connected by a pin 5 with a lever arm 5 fulcrumed at 5*. Removably secured to the forwardly projecting end of this lever arm 5 is a suitable presser device 6 adapted to operate upon the arms of which is journaled a cylindrical roller 9, so that this roller also receives a bodily reciprocatory or vibratory motion.

The sole and shoe with the last therein are conventionally illustrated in section in operative position with regard to the edging apparatus.

In using our improved apparatus it will be understood that the plastic sole having been laid upon the bottom of the shoe the last and shoe are then held in an inverted position and the outer surface of the sole is brought into contact with the vibratory roller 9 and while being pressed thereagainst by hand is moved back and forth in a path at right angles to the plane in which the roller 9 reciprocates, the hands naturally yielding sufliciently to allow the reciprocatory or vibratory movement of the roller.

The result of this is that the roller rolls over the surface of the plastic sole and the impacts given by the rapid vibrations press it into firm adherence with the bottom of the shoe. The shoe may be tilted while in contact with the roller 9, so as to cause the sole to be rounded over the sides of the shoe.

It is for pressing this turned-over portion of the sole firmly into position that the presser device 6 and guide roller 8 are provided, and to utilize this the shoe is turned until the sole is brought into vertical position when it is pressed against the guide roller 8. lVhile so pressed against the guide roller 8 it is moved transversely of the axis of the guide roller and the reciprocatory or vibratory presser device 6 strikes the said turned-over edge of the sole with great rapidity, pressing said turned-over edge into firm contact with the bottom edge of the upper.

The gage roller 8 is preferably of convex form and the presser device has a curved end which extends approximately concentric to the surface of the gage roller. This enables the last and shoe to be tilted, so as to bring the sole at any desired inclinations to the axis of the roller to cause the pressure device to act with the best effect upon the turned-over edge.

hat We claim is 1. In combination a gage roller j ournaled upon a stationary axis and having a con-' vex surface and a vibratory presser device ofiset from said surface and reciprocating in a plane parallel with the axis of said roller.

2. In combination a suitable support, a lever arm pivoted thereto, a cylindrical roller supported from said lever arm, means for vibrating said lever arm, a gage roller jonrnaled on a stationary axis and a presser device carried by said lever arm in proximity to said gage roller.

3. In combination a gage roller having a convex surface, a vibratory lever with means for operating it and a presser device carried by said lever having an operating portion curved approximately concentric to the surface of said gage roller.

In testimony whereof, We affix our signatures in presence of two Witnesses.
