soLE CEMENTING MACHINE Application led November 18, 1930. Serial No. 496,420.

This invention relates to sole cementing machines.

It is an obj ect of this invention to provide a machine which will apply cement evenly and quickly regardless of whether the sole edges are scarfed off or are flat.

It is a further object to provide a machine which will insure that the cement is deposited at a predetermined rate and that it is thoroughly applied to the surface of the sole.

It is a further object to provide a machine which will confine the cement to the parts desired without gumming up the machine or the work.

Itis a further object to provide a machine which will be simple and reliable in operation and which will be easy and economical in manufacturing Other objects of the invention will in part be obvious and will in partappear herein.

taken in connection with the accompanying drawing, in which:

Figure 1 is a top plan 'view of a machine this invention. I Figure 2 is a side elevation of the same machine. i

Figure 3 is a front elevation thereof.

Figure 4 is a rear elevation thereof.

Figure 5 is a side elevation of the cement applying wheel.

Figure 6 is an endv elevation of the wheel.

Figures 7 and 8 are details showing the mechanism .for holding the sole in engagement with the cementing wheel.

Similar characters refer to similar parts throughout the several views.

In the drawings the numeral 11 designates a cement tank supported upon a pedestal 12. A shaft 13 is journalled at one end in the front wall 14 of thc tank as shown at 15; at

the other end it extends through and is journalled in the rear wall 16 at 17. This shaft carries at its front end a cement applying wheel 18 so disposed that its lower side will dip into the ycement within the tank while its upper edge 19 extends upward through a slot 20 in a section 21 of the top wall 220i the tank. v

The other end vof the shaft 13 is provided with a `drive sprocket 23 external to the tank, which sprocket is driven by a chain 24 from afsprocket pinion 25 which in turn is driven The surface ofthe wheel 18 is cut to provide teeth. The shape and dimensions of these teeth determine in great measure the amount OF WINTHROP, MASSACHUSETTS, ASSIGNOR TO COMPO SHOE MACHINERY CORPORATION, OF NEW YORK, N..Y., A CORPORATION OF DELAWARE vthrough spiral gears 26-27 from a motor 28.

of cement applied. They may, therefore, be p varied with diferent cements. With the commercial cements of today, however, they will preferably have one substantially lradial surface 30 and one inclined surface 31 which may make an angle of 45 degrees with the radius. These teeth will preferably bel 1/32 apart at the periphery. A plurality of circumferential grooves 32 about 1/64 deep are cut in the surface of the wheel to assist in maintaining a continuous film ofi-cement over the surface.

The cement tank is intended to be filled withcement up to a level .33, `below the shaft 13, but suiiciently high for the wheel 18 to dip into it and become thoroughly coated. To lthis end a fllinglopening is provided, having a cover 34.

The portion 21 of the top of the tank is hinged to the portion 22 at 36 and carries with itthe presser lements so that as this portion 21 is raise free access may be had to the interior of the tank. A catch 37 holds the portion 21 in place.

A standard 4() is carried upon the portion 21fbyscrews 41 operating in slots 42 in the base 43 ofthe standard s0 that the position of the 'standard may be adjusted relative to the cement wheel 18. This standard carries a head 44'mounted to slide vertically. This l Slidingly supported in the head 44, are a pair of vertical rods 48 and 49 each carrying at its lower end a roller 50-51, each adapted to cooperate with a portion of the peripheral surface of the wheel 18. The roller 50, carried by the rod 48, has a cylindrical peripheral surface lapping over the'outer surface `of the wheel 18 while the roller 51 has a conical peripheral surface with its larger diameter away from the roller 50'.

rfhe -rod 49 is urged downwardly by a spring 52 which bears against the head 44, and a stop 58 limits the movement of the rod relative to the head. v

llihe rod 48 carries a collar 54 between which and the head 44 is provided a spring 55 which serves to raise'the rod 48 when it is not otherwise forced downward. A sleeve 56, upon the rod 49, provides a means for adjusting the tension of the spring 52.

lEach of the rods 48 and 49 is provided with a4 pin 60-61 in position to beengaged by a rocker arm 62 pivoted to the head 44, and the position of these parts is such that if the machine be in engagement with a portion of a sole which is not scarfed, the thickness of the leather will force the roller 51 upward, as seen in Figure 7, andthrough the medium of the rocker arm 62, exert downward pressure upon the roller 50. So soon, however, as a scarfed portion of the ,sole passes beneath the roller, see Figure 8, the roller 51 is per- Y mitted to descend, relieving the pressure on the roller 50, thereby permitting the sole to tiltand presenting the scarfed surface fiat against the cementing roller 18.

A guard 65 is carried by a rod 66 which is slidingly mounted in a tube 67 extending upwardly from the bottom of the cement tank to above the cement level. A spring 68 forces the guard upwardly and a' nut 69 draws it downwardly.

The guard 65 is bifurcated to embrace the sides of the wheel 18 and has a surface 7 0 parallel to the cement applying surface of the wheel 18. By reason of the fact, however, that the guard is above the axis of the wheel, the vertical movement of the guard varies the radial distance between the surface 70 and the wheel periphery and thereby Varies the amount of cement carried upward by the wheel.

vlin operating the machine, the motor is turned on thereby covering the surface of the revolving wheel with cement. The operator then slips the edge of the sole beneath the rollers and it is carried around to the end of the cemented area, automatically adjusting itself to the condition of the edge of the sole, whether scarfed or not.

Since certain changes may be made in the l. above construction and different embod1 ments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the rseaeai above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
