SHANK-BEATING' AND s'r-IrcH-ItuhBING MACHINE.

Original No. 1,521,877, datedlanuary 6, 1925, Serial No. 515,668 men November is, 1921. Application for reissue filed November 23, 1926. Serial No. 150,359.

My present invention relates to shoe mamachine's of-thi's character sis-heretofore constructed, it was customary to have different shaped beating irons fastened on the end of a shaft adapted to rotate at the proper speed and the shank of the shoe heldagainst .it to beat downthe edge of the sole at the shank close to the upper, and this same operation was utilized in rubbing down stitches. This operation was diflicult to'perform, however, as it was diflicult to hold the shoe inproper position and' to move it quickly while simultaneously pressing hard .partic'ular operator; that is, different optoperform the work. Applying pressure to the work was very apt to cause theshoe to slip out of position and was the source of in ury to the shoe, this accident happening frequently, especially to new and i-nexp'erienced operators.

I have overcome the above named difficulties with my present invention by the provision of an edge guide associated with the beating. ironxa'nd so constructed that it will not in ure a shoe even though the shoe slides orslipsover the same, and also by the provision of a guard with a concave clearance possible injury to the-shoe is prevented.

The principal object of my present invention, therefore, is'a'n improved shank beating and stitch rubbing machine. I

Another object is an improved guiding 45. means for preventing injury to shoes during the shank beating and stitch rubbing operations.

7 this Still another object is an improved beating through the shank beating and stitch rubbing head;

Fig. 4 is a horizontal longitudinalsection through the shank beating and stitch rubbing head, and

vFig. 5 is a front elevation of the device shown in Figs. 3 and 4.

Referring to the drawings, 10 designates a basehaving a pedestal 11 formed integral therewith, and slidably mounted for vertical movement in said pedestal is a head 12, bolts 13 in, the pedestal operating to hold the head 12 in any desired adjusted position. Boxes 14 and 15 are heldin the head 12 in split bosses, but one ofwhich, 16, .-is shown, arrangement allowing for endwise movement of the boxes 14 and 15, and in addition, in the case of the box 14, such arrangement allows for angular adjustment. This'latter is particularly advantageous, as-

it enables the relative position of the devices carried by the box 14 to be adjusted to the erators force the'work intoengagement with the operating tool at different angles and .it is essential that an operator,who, for example, lifts the work upward'and rearward toward himself, be able to adjust the working parts of the apparatus to accommoby bolts 22. ;The"free endof this shaft 21 carries an idlerpulley; 23 and a driving pulley 24-, a pulley 25 being attached to the driving pulley 24. "The pulley 25 is in verica'l alinement with the pulley 18 on the shaft 17 and a. belt 26 passes overthe same to rotatethe shaft- 17 and attached parts. A boss 27 formed integral with the base 10 has pivotally mounted therein the lower end of a-belt shift rod 28, forked arms 29 attached to the rod engaging the sides of a driving belt 30, which extends from any suitable source of power over the. pulley.

Secured to the free or exposed end of the box 14, by screws 31, is a guide carrier 32, this guide carrier being perforated to allow free rotation of the shaft 17. Surrounding the reduced end of the shaft 17v and in the rear of the guide carrier 32 is a felt packing 33, the purpose of which is to prevent oil or other lubricant from seeping through the box 14 and onto the shoe being operated on. K

Slidably mounted in the guide carrier 32 is a guide 34, the outer end of which is rounded to follow the diameter of the beating iron. This guide 34 is forced'outwardly of the guide carrier 32 by springs 35, a pin 36 in the guide 34 working in a slot 37 in the guide carrier 32 limiting the outward, as well as the inward movement. Fittin upon the tapered end 19 of the shaft 17, and. held thereon by a screw 38, is a beater iron 39. The outer end of the beater iron 39 is reduced in diameter to receive a guard 40, which is countersunk at 41 to a depth and diameter sufiicient to receive and cover the screw 38, thereby preventing possible injury to the work. This guard 40 is reduced in diameter at 42 to clear the channel leaf of a shoe so as to allow full pressure of the beating iron 39 tobecome effective and at the same time prevent damage to the shoe being worked upon, in case the operator moves the shoe out of operative position. The heating iron 39 is made with a taper hole, thereby strengthening the end of the shaft 17 and avoiding the breaking of such shaft on account of the pressure that is continually being applied against it during the operation of the machine. These beating irons may bemade in different widths to suit the work and the working edges slightly rounded to avoid scuffing. The great advantage of having the guide 34 movable as to depth is that the thickness of the edge of the sole varies from a feather edge to one-eighth of an inch or more in thickness. The lip of the guide extending about oneeighth of an inch allows for a ready locating of position of the shoe for operating on and yielding readily to pressure does not interfere with the beating iron getting down to work regardless of whether the leaf is thick or thin, as the guide does not revolve, it is easier to hold the shoe in proper position when moving it during the beating and stitch rubbing operations. The guiding edges of the guide, both front and bottom are rounded to allow for moving the shoe to follow the contour or shank of the shoe.

This cannot be done on a rptary guide, on account of the danger of damaging the upper if the shoe slips out of position.

In operating, to beat down the shank of the shoe close to the upper, the edge of the sole at the shank is pressed at the proper angle against the beating iron which is re- VOlVing' at the proper speed and is positioned laterally by the guide, which is easily located and kept in contact with the shoe. The operator beats down the shank and before replacing the shoe also rubs down the stitches, doing both operations with one handling of the shoe.

lVhile I have described the preferred embodiment of my invention somewhat in detail, it is to be understood that I may vary the size shape and arrangement of parts, constituting my invention within wide limits .without departing from the spirit of the invention.
