The object of this invention is to provide Inthe drawings, referring t Figs. 1 to 9,

a simple, practical machine which shall be inclusive, 15 s an 611611885 a d Which maybe capable of neatly and expeditiously performed of any suitable material and which 5 of very thin flexible steel having its working face provided with teeth extending diago ly tho-memes similar to file of certain class. A longitudinal movement is imparted to the band 15 by suitable means such as two pulleys 16 and 17 to which said band is connected, said pulleys being mounted to rotate ject of the machine of this inventlon'ls to upon a suitable frame. 18 and the pulley 16 being driven byadriving pulley 19.

Secured tothe frame 18 is a bracket 20 constituting alsup'port for the means for 3 positioning the shoe with respect to the band 15, such positioning means including two edge gages 21 and 22, v two breast gages 23 and 24 and a crease gage 25. The edge gages 21 and 22 are adjustably mounted upon the bracket so as to be capable of being adjusted transversely of the line of travel of the band 15, one of these gages with respect to the edge gages 21 ilndQQ so being arranged to bear against thesole edge on, one side of said band and the other arranged to bear against the sole edge on the other 81(16' of said band; In practice, these gages will terminate in the plane of the working face of the band thus limiting the movement of the sole edgetoward said working: face.

1 The breast preferably are formed as flanges on'aplate 26 secured to thefend of the bracket 20 between the edge gages 21 and 22, said plate contacting with the band 15 opposite to'its working surface and serving as a means for isupportingsaid band against thepressure upon said workmgjface when the shoe is The crease gage 25' placed thereagainst. I constitutes also a means for guarding the shoe'upper against the action of the band 15, said gage being preferably a verythin temon the bracket 20 and said gage being preferably somewhat resilient so as to be capable of yielding to. a certain extent toward the working'surfa'ce of the band 15 if suflicient pressure is applied thereto. This' gage is adapted to enterthe crease between the up per side of the sole and the upper of the shoe thus positioning the shoe sole longitudifnally of the band 15 and with respect-to the edge gages 21 and 22. The gage 25 may be and preferably is adj ustably mounted on the.

bracket 27 so as to be capable of beingadjusted longitudinally of the band 15 and that said edge; gages may be caused to'bear against the edge of the shoe sole at any desired point in its thickness. The bracket 27 may be and preferablyis adjustably mounted on the bracket 20 so as to make it possible to adjust the crease gage 25 transversely of the band 1.5 toward and away from the working face thereof. I

The operation of the form of my invention'hereinbefore specifically described is as follows: The shoe, after being operated upon by the heel trimming cutter and the shank trimming cutter, has a certain amount being gages 23 and 24 may be and said pulleys.

of material forming a bunch upon the edge of the shoe sole at the shank portion thereof adjacent to and in front of the heel breast,

as clearly shown in Figs. 3 and 4. The ob-' perform this final trimming operation, the

shoe is placed, as shown in Figs. 2 and 3, With the breast gage 2 1 against the breast of the heel and the crease gage 25 in the crease between the sole and the upperof the shoe so that the working face of the band 15 contacts with'the edge of the shoe sole, as

"shown in said figures. Preferably, the band '15 travels in the directionof the arrow, Fig. '2, that is, from the lower toward the upper t willbe understood side of the, shoe sole.

that'the pulleys'l6 and 17 may be made quite 7 large in diameter So that a very high speed of the band 15 may be obtained without a very high speed of rotation of the shafts of As pressure is applied smoothly remove thefmaterial soughtto be to the sh oe'to' carry 7 theedge of thesole toward the working face of the band, said band actsto rapidly and r removed and the proper cross sectional shape of the sole edgemay be obtainedby manipulating the shoe; it being evident that if the sole edge is required to be rounded the shoe may be rocked to a sufiicient extent to produce the deslred curvature, the edge gages 21 and 22 andthe crease gage25 being constructed and adapted to permit such movement. I

here one edge of'the shoe sole is being operated" upon, as shown in Fig. 3,'tl1e edge gage 21 finally encounters the edge of the sole at a point forward of the breast of the heel, and the edge gage22 encounters the constitutes a part of the heel,'.it'being evident that'thesegages prevent the band 15 from cutting into the'sole edge beyond the proper depth and that the breast gage 24 1S so constructed and arranged as to permit the Ward or'from said'band, the edge gages 21 and 22 being provided for limiting the "movement of the shoe toward the band. The

gage 25, as before stated, is interposed between the working face'of the band and the upper of the shoe and, consequently, serves as a'means for guarding the shoe upper against the action of the wo-rking'face ofthe baud and thus protects the shoe upper from 11o side of that 'portion of the'sole edge which I injury. After, one; side of. the {shoe sole has been cut in v or trimmed, asherei'nbefore described, theshoeis reversed and tl eibreast of the heel placed against the breast, gage 23,

In some cases shoesoleshavea very; close there is but, very little edge, that is to say, eXtension-beyondthe side ofithe upper, and in operating on shoes of, this elassit is desirable to employ anieans for deflecting the band from a straight path. InFigs, 10 to 12, inclusive, Ihave illustrated another embodiment of my invention,particularly constructed for work of this class. In this em bodiment of my invention, 28 is-a band suitably formed to cut or abrade the edge of the shoe sole, as in the form of my invention first described, thisband having a longitudinal movement imparted thereto by pulleys 29 and 30 journaleduon a suitable frame 31 and driven by a pulley 32. Secured to the frame 31 is a bracket 33 upon which are sup.- ported the means for positioning the shoe.

for deflecting the band from a straight course so as to make it possible to operate on shoes having a very close sole edge.

Adpistably mounted same functions as the breast gages 23 and 2st of the form of my invention first described.

Interposed between the edge gages 3% and, 35 is a wheel 38 which may be ournaled on a any suitable support and in this instance is journaledupon said gages, said wheel bearing against the band 28, thereby serving to deflect said band from a straight course and also serving as a means for'supporting said band against pressure on the, worlzingsur-w sole. The gages 34c and serve to deter mine the extent to which the sole edge can be moved toward the working fa ceof the band'28 and in practicethe extremities of said gages are located in the plane of saidworking, face. These edge gages, t WlllbQ noted,, as well, as the breast'gages 3G and 37, pro ect upon the opposite sides of the band 28 andguide the same, thus preventing any tendency of I the proper flected away on the bracket ,3?

are two edge gages 3i and 35, corresponding to the gages 21 and 2'2,respectively, and also secured to said bracket are two breast gages 36 and 37, respectively, which perform the i band 28 and with respect to the;

Having thus described my invention, what I claim and desire by Letters Patent so secure is: a
