COMPANY. .OF YNN; MAS$ACHU$ETTS,

HEEL-BREAS TING MACHINE.

To all whom it may concern: j

Be it known-that I, EDWIN A. WEBS ER, a

citizen "of the United States; residing at Haverhill, in the county of Essex and State of Massachusetts, have invented an Imwhich is adapted to cut from side to side, 01'

transversely ofthe heel in breasting the same.

The object of my invention is to provide a machine of this type with meanswhereby the shoe may be quickly placed and securely held in the desired positionfor breastinggso that the breasting operation may be quickly performed, without injury to the shoe, and

further to provide means wherebythe machine maybe readily adapted for different Styles and sizes'ofheels.

'I accomplih these objects by the means shown in the accompanying drawing in which 2-. i n l Figure 1 is a front elevation of a heelbreasting machine embodying my invention. Figs. 2 and 3 are side elevations ofthe head portion of the machine viewed from the left and from the right respectively. Fig. 41 is a sectional view of the knife clampytaken on 11M4 4 of Fig. 2. Fig. 5 is ahori-zontal sectional view on line 5-5 of Fig. 2. Fig. 6 is a detail view of the top-lift-engaging plate. Fig. 7 is a detail sectional view of the heelsupport.

The machine illustrated is of the well known foot-power type, comprising a frame 10, having a knife-carrier 11, mounted to reciprocate vertically therein, said carrier being connected to a treadle 12 by an.inter-' mediate linklS and being provided with a returning spring 14, as shown. v The breasting-knife 15 is arranged to depend vertically from the carrier 11 and is se cured thereto by means of a knife-clamp, shown in detail in Fig. 4, comprising twomembers 16 and 17, which are secured to the carrier by bolts 18, said knifebeingcurved transversely to correspond to the particular shape, or curvature of the particular shape of'heel-breast which is to be formed. A verto that type laid thereon the tically disposed-post -19 is mounted in brackets 20 and 21, secured .to the front side of the "machine, directly beneath the knife 15 and a heel-support is mounted on the upper end. thereof, said support comprising a base '22 having an upwardly projecting ,heel-sup-' port 22 thereon. Theiupper surface of said support is inclined down from its side-face 22/,

back ofrthe breasting-knife and arranged closely adjacent the path thereof, so that the cutting edge of the blade passes in close proximity to theraised edge of the support,

j which face .is perpendicular and .is curved to correspond to the shape of the whereby said edges may coeperate to act as a shear!" The shearing edgeiof the support is inclined upwardly from the outer end thereof to correspond with the ordinary taper of the heel, so that, when the side of theheel is perpendicularly: As I prefer to perform the shaved, it is not necessary to havethis edge fit against theaside .of the heel exactly. v2

support 22 is such that the side of the heel,

top lift. will besupported heel-breasting operation. before the heel .is

when resting thereon, is onlyengaged by the 1 shearing edge "ofi 'sald support, so that the heel maybe" tilted thereon to any angle at which it may be necessary to hold the heel to breast itfat the desired angle, as'indicated in Fi .7.v I a. 1 I i ii shankrest 24;, consisting of a vertically secured at itslower. end, .to an angular v secured to the post 19 by a bolt 26. Said shank rest is arranged adjaextending post, having 'a rounded surface, is

centthe front end of the heel-'support and extends adjacent and parallel to "the side edge of the breasting-knife, which, when in use, passes in close'proximity to the shank of the shoe, adjusted in the desired relationto said knife the openings through which said bolts 26 and 27 pass areelongated,-so that it may be moved from right to left. and from front to rear. I

. A top-lift rest 30 is provided adjacent the inner end oftheiheel-rest 22', said top-lift rest beingsupported so that it may be adandtopermit said rest to be justed to varying conditions. i The particu- 5 lar means which I employ for providing these adjustments may be described as follows :A bracket 31 is clamped on the frame by means of a bolt passing through a vertical slot 32 in said bracket, to perm-it the same to be moved vertically and clamped in different positions of vertical adjustment. Said bracket 31 is further provided with horizontally disposed guideways, in which an angular shaped bracket 33 is mounted to slide and a bolt 34 passes through'an elon' gated slot 33 therein, sothat it may be moved forwardly and rearwardly and clamped inthe different positions desired. The bracket 33 is also provided with guideways' which extend atright angles to the guideways in the bracket 31, and a clip 35 is, in like manner, connected to the bracket 33 by a bolt 36 which passes through a longitudinal slot in said clip. The heel rest plate 30 is pivotally mounted on said clip 35, so that it may be tilted either to the right or the left, and a pair'o'f stop-screws 37 are mounted therein atoppesite sidesof said pivot, so that, by. loosening one of said screws and tightening up on the other, the plate may be held in different angular positions.

With the above described adjusting means, the plate 30 may be moved horizontally in the plane of its heel-engaging face according to variations in the pitch of the heels, or it may be moved horizontally from front to rear, at right angles to said face, according to variations in the height of the; heels, and it may also be tilted to vary the angle at which the top-lift of the .heel'is held, that is, ac-

cording to the tread ofthe heelf In breasting a heel, the shoe i'srso placed in the machine, that the edge-portion of the heel rests on the shearing. edgefof the support, its top-lift :restsrflat against the plate 30 and itsshank bears again'stthe rest24, the heel being tilted to the desired inclination on the heel-support. The treadle is then depressed and the knife forced downwardly, removing a chip from the breast of the heel and forming a breast face ofthe de Copies ofthis' patent may be obtained sired shape. With the above described arrangement the shoe may he quickly placed in position and removed therefrom, and, as the breasting-operation may: bedone rapidly, the whole-operation may be quickly and accurately performed. The machine may also be readily adjusted'to varying conditions of pitch, height and tread, and, if the heel of a left shoe is to be breasted at a diiferent angle than that of a right shoe, it is merely necessary to tilt the heel to the correct position.

. I claim p i l. A heel-loreasting machine having a ver tically reciprocating knife-holder, -a breast ing-knife depending'therefrom and a 11861.

support having a vertical side face conforming to the back of said knife and disposed in close proximity to the path thereof to form a shearing edge, the top surface of said support being inclined downwardly from said edge to permit the heel to be tiltedinto different positions thereon, and a top-lift rest vertically disposed at the top-lift engaging end of said edge, substantially as described.

2. A heel-breasting machine having a vertically reciprocating knife-holder, a breasting-knife depending therefrom and'a heelsupport having avertical side'face conforming tothe back of said knife and disposed in close proximity to the path thereof to form a shearing edge, the top surface of said support being inclined downwardly from said edge to permit the heelto be tilted into different positions thereon, and a vertically extending shank-rest arrangedadjacent the heelsbase engaging end of said edge, substantially as described.
