MACHINE FOR OPERATING UPON THE SOLESOF BOOTS AND SHOES.

Specification of Letters Patent.

Patented Nov. 23, 1915,

Application filed September 25, 1912. Serial No. 722,275.

To all whom it may concern: a s

Be it known that I, JAKOB Tamar, a subject of the King of Bavaria, residing at Frankfort-on-the-Main, in the Kingdom of' Prussia and Empire of Germany, have invented certain Improvements in Machines preferably for consolidating the marginal portion of the sole.

The machine hereinafter described is more particularly designed for use in the manufacture of shoes, the soles of which are provided with what is known as an English channel ora channel formed as a slit which is cut at a comparatively large angle to the tread face, approximating a right angle. As herein employed, the term sole is used in its generic 1 sense to. include not i only thesingle sole of theusualMcKay,

pegged or nailed shoe but also a double or tapped sole andthe combined'welt and outsole of a welt shoe. Various operations performed upon a shoe during the process of manufacture tend to separate the walls of'the slit or'channel in the tread face wherein the outseam lies. For example, during the leveling operation, the margin of the sole is forced toward the upper of the shoe, thus tending to open the channel; Howeveiy'in order that thefinished shoe may have its maximum marketable ,value, it is important that the channel shall be tightly closed and be as nearly invisible as possible. s 7

Accordingly, the principal objectof this invention is to provide novel and effective means for closing the channel and preferably for consolidating and finishing the edgeof the sole at the same time. 7

With this object in view, one feature of the invention comprises the provision of a pair of rotary tools located onefwithin the other and constructed and arranged to act respectively upon the edge and upon the tread face of the sole, together with means for imparting rotary movements in opposite directions to the tools' In the illustrated embodiment of the invention, the tools are located concentrically, one tool'being shaped andoperated to close the channel in the face to of the sole and the other to beat or pound the edge of the sole and thus assist also in s closing thechannel, in addition to consoli dating and finishing the sole edge. Pref;

erably, each of the two tools is cylindrical in form and is provided with spaced teeth at one end which constitute the active elements of the tool,

In addition to the features above specifically referred to, the invention comprises also certain other comblnations and arrangements of parts and features of construction which will now be described in Figure l is a side elevatiompartly 111 secs tion, of the head of a machine embodying the invention in its preferred form; Fig.

2 is a similar view upon a larger scale of the channel closing tool; Fig. 3 is a still larger detail view'of one of the teeth of p the channel closing tool; and Figs. 4 and 5 are end and side elevations respectively of the edge beating tool.

As illustrated, the head 2 of the machine supports in suitable bearings a hollow shaft s 4 and a concentrically arranged inner shaft 6. vThe channel closing tool 8 is mounted upon the shaft 4 so as to be slidable axially thereonbut it is, compelled to rotate with the shaft by means of a spline 9 fixed to the shaft and provided with an outturned end 10 which extends into a keyway 11 in the tool 8. The end 10 of the spline not only causes the tool 8 to rotate positively with shaft 4 but it also prevents the tool from sliding off the end of the shaft. A spring i 12 surrounding the shaft and interposed between therear end of the tool and a collar 14 fixed to the shaft tends constantly to maintain the tool in its extreme outer position. s i

The outer end of the tool 8 is formed with a series ofspaced teeth 16, the ends 18 of which are constructed and arranged to wipe v over the tread face of the sole during the rotation of the tool so as to close the chan nel. As clearly illustratedin Figs, 2 and 3, the faces 18 are beveled in two directions. They lie approximately in-a conical surface theaxis of which is the axis of the tool 8, thus being beveled to correspond substantially with the transverse curvature of the sole B of the shoe A,'as shown in Fig. 1. The faces 18 are also slightly beveled apthe tool so that an increasing. pressure will be exerted upon the sole'adjacent the channel C as each tooth'travels over the sole:

Arranged concentrically with tool 8 and fixe'dto the'inner shaft'6 is the edge beating tool 22 which is also provided with teeth 2% which project outwardly beyond theteeth 16 of'the tool "8.' Theteeth 24 are so spaced "that in the rotation of the tool'a' rapid succession ofblowsis imparted to the edge of the sol'eiwhich not only assist in closingthejchannel, but also finish and consolidate thesolef edge, makingIitsinooth, hard and regular in shape. Thetwo shafts and the two F tools carried respectively thereby are rotated independently and diver'sely through v the

pulleys

26 and 28. Preferably the tools are rotated in opposite directions, causing the machine to run with less vibration and resulting in a more effective operation. upon the sole. 7

A rest for the tread face of the vsole is. provided in the form of a freely rotatable k Y r011 30 mounted upon a spindle 3'2 fixed: in

an arm 34. By means of a bolt 36pas'sing through arm 34 and through an elongated slot 38- in a bracket l0, the arm, and there fore the roll 30, may be clamped lto the bracket after it has beenadjusted vertically.

and angularly as desired. Oonveniently,the

angular adjustment may be secured by a set screw 42 threaded through a lug 44 upon the arm and impinging against the lower surface of the bracket 40. This bracket is mounted to slide horizontally in a guideway in the; frame 2 and can be secured in ad justed position'by a set screw 46. v c

The manner inwhich the machine may be used in'operating upon the sole B of a shoe A for the purpose described will be readily understood from the foregoing description read in connection with the accompanying drawings. The sole rest 30 is'ad'jus'ted to support the sole of the shoe in proper rela- V tion to the teeth of the two tools 8 and The operatonholding the shoe in his hands, presses-the sole, inwardly. and upwardly against the teeth of the tools, as shown in Fig.1, compressing the spring 12. He then feeds the shoe along so as to presentthe desired portions of the sole progressively to the tools, with the result that as the toolsare rotated in oppositedirections the ends 18 of teeth'1i6 wipe over and beat the tread face of the sole toclose the channel while the cylindrical surfaces of teeth 24 fp ej ,7 Having thus -indicated the nature and s scope ofthe invention and having. described in detail a machine embodying the 1nvention in a preferred form, what I claim as 1.
