This invention relates to the finishing of Louis and, similar heels and particularly to the shaping of the shank portion of such a heel or that which extends forward from the breast of the heel toward or along the shank of-the shoe. I

\ It is the objectofthe present invention to provide a machine of this general type which is adapted to impart a better finish to the heel and which is 'c'a-pable'of far, greater production capacity than has been possible with ma-, chines of this type heretofore.

' Before explaining in detail the present invention, and "the method-or mode ofoperation embodied therein, it is to be understood that the invention is not limited in its application to the details ofconstruction and arrangement of parts illustrated in the accom panying drawings, since the invention is ca pable of other embodiments and of being practised or, carried out in various ways. Also itis tobe understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation, andit is not intended to limit the invention beyond the terms of the several claims hereto appended or the requirements of the prior art.

v The invention will be more clearly understood from the following description in conjunction with the accompanying drawings; in which, Fig. 1 is a front elevation, partly insection, of a machine embodying the invention; Fig. 2 is a plan viewof the same i Fig. 3 isasimilar view showing the work engaging the shaping tool; g Fig. dis an enlarged side elevation of the work carrier and associated part-s; Fig. 5 is a planviewthereof looking in the direction of the arrow in Fig. 4;

Figs. 13 and M- are a vertical section'and front elevation respectively of a heel blank. While, as willher'einafter appear, the m achine of the invention is. adaptedv for useinconnection' with heels of a. I wide variety of forms, a typical heel of the type to which the invention is applicableis shown at Ain Figs.

taken on the line i 13 a d 14, Said heel in as finishedformis I adapted to engage and fit the heel seat of the shoe, a suitably shaped back orbody porprovided with a concave upper surface a" gaging portion a as most clearly shown in i Fig. 14. The .heel seat engaging portion a,-

breast b and back Z are formed prior to the transverse shaping of the shank cby instrumentalities which constitute no part of the presentinvention. The heel blankfafter the operationv of said inst-rumentalities has a 1 shank of the shape indicated by dotted lines in Figs. 13 and 14, the underside thereof adjacent the breast I) being transversely straight as the result of the formation of said'breast b, which gives said shank its proper vertical curvature but leaves, particularly at thesidesof the shank, a. quantity i of surplus material 6 which is subsequently removed to finish the shank. The present inventionis directed to the subsequentshap ing or finishing of the shank. c, by removing this surplus material 6, to give said shank its proper transverse curvature in parallelismzto'the heel seat engaging portion a.

The bracket 126 i a'dj'u'stably mounted upon the carriage 21 as byja thumbserew lsijpassg in through a slot 129 in the bracket 126 and engaging the carriage 21. In order to permit movement of the heel blank -A toward the shaping'tool B Without being obstructed the breast gage 125, the latter is curvedin the direction of movement of the Work. The positioning of the blank duringthe rotation of the carrier with the breast of the heel at right angles toits axis assists in r yentin' itsobstruction by the breast gage. The our:

vature of thebreast'gage also permits'the in- .f

serti0n ofthe heel blank; during a considerable range of movement ofthe carrien. I

. In operation the carriages '21 and 23 are moved to suitable positions with respectto the shaping tool B by manipulation of the adjusting screws 22 and 24. The spacer 116 is turned out of engagement jw'iththe head 11 5' of 'theshafj; 112 to permit said shaft to be moved axian andmdve the 'pi'nionfiao out of iiiesh with the gear12 1 ,thereby ,dis-

The clam ing bolt40is loosene-dto permit'adjust'm'ent o'f'the jack 30 by the adjusting screw 33; the jack then beingheld in adjusted position by tightening the clamping) bolt 40; The Work carrier45' is then adjusted angularlywith respect to a. plane perpendicular to the, shaft 20 to bring the breast of? the heel at right" angles to its aXis' of rotation. This is accomplished by loosening'the nut 4:9 {and clamp 28, permitting movement-ofthe Workcarrier' 45 to the desired position.- The nut 49 and clamp 28 arethentightened to-clamp'the work carrier in its adjusted position. The breast gage is then brought to the desired position to locate properly the position of the breast of the heel upon the workearrier by adjust ing the bracket 126-Vertically and the breast gage 125 horizontally.
