UNITED STATES LOUIS G. FREEMAN, OF CINCINNATI, OHIO.

SHANK-IBEATING AND STITCH-RUBBING MACHINE;

Application filed December 15, 1923, Serial No. 680,875.

My present invention relates to shoe machinery, and more particularly to a shank heating and stitch rubbing machines applicable for finishing the shanks of welted boots and shoes.

In my prior application, Serial No. 515,- (SGS, filed Nov. 16, 1921, now Patent No. 1,521,877, issued January 6, 1925, for shank beating and stitch rubbing machines, I

1 have described and claimed an improved form of combined beating iron and guide, the guide in such application being nonrotatable, but slidable transversely of the axis of rotation of the beating iron. In my present invention I have designed a new and improved form of combined guide, beating iron, and guard and find that the guide is preferabl Y made to rotate with the heating iron. My present form of guard is formed integral with, or secured to, the beating iron and rotates with the same and I find that such structure is more efiicient and easier to manufacture and use than the type of tool heretofore employed. My

present invention is to be consider-ed an improvement over that shown and described in my copending application above referred to.

The object of my invention, therefore, is an improved combined guide, beating iron,

39 and guard for use in a shank beating and stitch rubbing machine.

In the accompanying drawings illustrating the preferred embodiment of my invention,

Fig. 1 is a front elevation of a portion of the machine to which my invention has been applied;

Fig. 2 is a vertical sectional elevation through my improved device with a shoe whose shank is being worked on shown in dotted lines, and

Fig. 3 is an end elevation on the line 33 of Fig. 2.

Referring to the drawings, 10 designates the pedestal of a shank beating and stitch rubbing machine in which is slidably mounted for vertical movement a head 11, bolts 12 in the pedestal 10 operating to hold the head 11 in any desired adjusted position. Self-alining bearing boxes 13 and 14 are held in the head 11 and rotatably mounted in the boxes 13 and 14 is a shaft 15 provided at one end adjacent the bearing Renewed April 28, 1926.

shaft 15 remote from the pulley 16 is reduced in diameter at 18 to receive the device forming the subject matter of my present invention.

This device consists of a tapered body portion 19 having formed integral with, and at its outer end, a beating iron 20, though it is to be understood that the beating iron 20 may be formed separate from the body member 19 and secured thereto in any suitable manner. Numeral 21 designates a setscrew by means of which the body member 19 and beating iron 20 may be secured to the reduced end of the shaft 15. The joining portion of the body member 19 and beating iron 20 is in the form of a fillet 22, this fillet or clearance 22 being deep or sharp enough to form a seat or enclosing portion for the channel flap 23 of a shoe 24 be ing worked on. Secured to the outer face of the beating iron 20 by screws 25 is a guide 26, the diameter of such guide 26 being greater than the diameter of the beating iron 20 so as to allow the edge of the outsole 2? to lit in the angle formed by the beating iron 20 and the guide 26, as clearly shown in Figs. 1 and 2.

In operating, the device is placed on the reduced end 18 of the shaft 15, as shown in Figs. 1 and 2, the machine started in motion and the operator, holding the shoe in his hands, places the edge of the outsole 27 in the angle formed by the beating iron 20 and the guide 26 to guide the shoe while the beating operation takes place and moves the shoe forward and backward, exerting an upward and outward pressure on the shoe to force the ame against the beating iron 20 and against the guide 26. The taper of the body portion 19 is made steep enough to 9 form a space in which the channel flap 23 is protected from any possible injury during the beating and stitch rubbing operation. As the edge guiding portion of the beating tool may sometimes contact with the shoe upper, particularly at the shank por tion, I have defined this guiding means in certain of the appended claims as engaging the outer edge surface of the shoe, thus including the edge portion of the sole and the adjacent portion of the upper.

IVhile I have necessarily shown and described the preferred embodiment of my in vention somewhat in detail, it is to be understood that I may vary the size, shape, and

arrangement of parts comprising my invention Within wiijle'limits without departing from the spirit of the invention.

Having thus described my zwwhat I claim as new is:

1. In a shank beating and stitch rubbing machine, the combination oi a beating iron and channel flap guard formed integral with each other, and arranged end to end,

It) and a guide secured to the beating iron at 15 tion, a stitch beating portion, and a channel flap clearing and protecting portion.

3. ishank beating and stitch rubbing tool specially adapted to fit into the shank invention, 7

portion of the shoe, and adapted for extending acrossthe shoe bottom to operate upon the opposite edge portion of the shoe from the machine support, and comprising edge guiding means, stitch beating means, and channel flap guarding means.

4. A shank beating and stitch rubbing machine having in combination a beating iron, a channel flap guard formed integral therewith and providing a protecting space for the channel flap on a shoe being operated upon, and means to guide said shoe by engagement with an edge portion of the shoe.

In testimony whereof, I have signed my name to this specification.

LOUIS Gr. FREEMAN.
