WELT-STRETCHING MACHINE.

Application filed January 4, 1916, Serial No 70,207. Renewed March 27, 1917. Serial No.

Be it known that I, Lnoonn J BEDARD, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in felt-Stretching Machines, of which the following is a specification.

My invention is an improved machine for I operating on the welt of a shoe and it primarily has for its object to provide a machine for rolling the welt in such a manner as to push the upper back so that the needle of the stitcher can sew closer. The welt on an old shoe is usually kicked back at the toe so that itis a hard matter to get in between the upper of the shoe and the welt with the stitching machine, but by wetting the Welt to make it pliable and running it between the rollers on my machine the pressure and also the action of the lower roller running horizontally away from the shoe as it leaves the welt exerts a pull that stretches out the welt.

The invention also includes those novel details of construction, combination and arrangement of parts, all of which will be first fully described, then be specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the preferred form of the invention.

Fig. 2 is an enlarged detail front elevation showing how the shoe welt is rolled and stretched.

Fig. 3 is a top plan view of the parts shown in Fig. 2.

In the drawing, in which like numerals of reference indicate like parts in all of the figures, 1 is the stand having a bracket 2 in which the spindle 5 for the lower roller 3 is mounted, the lower roller 3 having a horizontal face 4 and 0f frusto-conical form so that it can get in close to the upper between the upper and the welt of the shoe.

The roller 3, it will be noticed, has its frusto-conical head provided with a flat, annular upper portion and is provided with a thin edge so as to readily project up into close proximity to the toe portion.

6 is a bearing lug in which the crank shaft 7 is journaled, the shaft 7 also forming the hinge pin on which the plate 9 is fulcrumed, the plate 9 having bifurcations 8 for the purpose. The plate 9 has a bearing 10 at its front in which the upper roller shaft 21 is Specification of Letters Patent.

-"ournaled the shaft 21 carr i11 a ear 17 t 3 y 23 Z? the crank that meshes with a gear 15 on by which shaft. 16 designates the crank power is applied to the roller.

The upper roller 18 has a collar 19 and is pinned at 20 to the shaft 21.

The roller 18 is of relatively narrow width to cooperate with the annular flat upper surface 4: of the roller 3 and the roller 18 is preferably milled to frictionally engage the welt of the shoe through the machine and the front edge of the roller is preferably rounded as best indicated in Figs. 2 and 3 of the drawings.

Pressure is applied to obtain the necessary squeezing action, by a treadle 13 connected at 12, with the lug 11 on the arm 9 and a coil spring 141: serves to oppose the treadle action to efiect the release or separation of the rollers.

In practice, in resoling shoes, it is customary to remove the old worn sole from the welt and it not infrequently happens that the welt is kicked back, particularly at the toe, so that the operation of the stitching machine is quite difficult to perform. IVith the use of my machine, however, after the welt has been moistened to render it pliable, it is rolled between the rollers 18 and 3, as shown in Figs. 2 and 3, with the result that the welt is pulled out and rendered compact, ready for the stitching operation.

From the foregoing description, taken in connection with the accompanying drawing, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art.

What I claim is:

1. A welt rollingmachine comprising a stand having a bracket, a lower roller journaled on said bracket to turn on a vertical axis, said roller including a head of frustoconical form having a flat annular upper portion, an arm hinged to said stand and having a bearing, a shaft journaled in said bearing, an upper roller carried by said shaft, said upper roller being of cylindrical form and having its front edge rounded and its peripheral face milled, said upper roller lying above the flat face of said lower roller, a spring tending to separate said rollers and a pedal device for drawing said rollers into proximity substantially as shown.

2. A welt rolling machine comprising a stand, a vertical cylindrical roller mounted cal roller, said horizontal roller being bevto rotate concentrically'ona horizontal axis, el ed to provide a thin. edge, means tending a horizontal roller beneath said vertical" to separate said rollers, an operator actuated 10 roller, said horizontal rol1er-11aving=-a--pe pedal device for drawing said rollers to- 5 ripheral fiat upper surface band located be- .gether to apply pressure to the same, and

neath said vertical roller and lying in a'plane 7 means for turning one of said rollers. parallel to the axis of rotation of said verti- LUDGER J J BEDARD.
