HEEL-ATT'ACI-IING MACHINE.

Application filed July 2c, 1922. Serial No- 576,286.

To all whom it may concern. a

Be it known that I, Josnrrr H. Porn, a citizen of the United States, and resident of Hamilton, in the county of Essex and State of Massachusetts, have invented certain Improvements in Heel-Attaching Machines, of which the following description, in" connection with the accompanying drawings, is a specification, like reference characters on'the drawings indicating like parts in the several figures. 3 i I My invention relates toinachines for the attachment of heels,it being particularly adapted for use in connection with heels carrying device s which are to secure them.

A heel of this character and of the Louis type is illustratcd in the patent to Finberg, No. 1,296,939, dated March 11, 1919, it having projections from theupper end adaptedto be forced through the heel-seat of a shoe and clinched over the insole. An object of this invention is to provide improved means for the effective application of pressure during the attachment of such heels, I In the attainment of this object, the heel is engaged only by contact withits sides, this, in a Louis heel, for example, being over the enlarged portion adjacent to the heel-seat. This hold upon the heel is independent of the varying angles between the heel-seat and tread-surfaces for different sizes and styles,

and also presents for these changes relatively slight differences in dimensions of the surface engaged. Such differences as exist may be compensated for by making a portion of the engaging means yleldable' In the form of my invention illustrated, the

shoe to be heeled is supported upona jack movable into'and out of attaching position, and there is an opposed iieel-engaging memher, which is open at the sidetoward the jack to receive the heel positioned upon the jackedshoe ready for attachment,"while the contact-surface of this member, which applies the pressure, is curved for engagement with the sides of heel. I I

In the attachment of the above-mentioned heels, in .fact of any form; heel, difliculty may been countered 1n ,producing a tight I obtain by means associated with the support;

As illustrated herein, the jackcarrying a slice for theheeling operation lias'a surface for-supporting said shoe, and surfaces in c'lin'ed-to the supporting surfaoet'or engagement with the pointsof the pi'ohgs or'other attaching devices, these surfaces being rela tively movablel "The V inclined -.surfaces, which act on the points of the'attaching devices,"may"be upon deflecting members operating. in openings in the A jack" in alinement withs'aid attaching devices, being shown'as upon upward: iprojections from the jack, While the sh -oe-support may consist of a plate surrounding the proj ectionsland being movable toyield along theInL I These and other ob-jects of the'iinvention areachieved by the employment of the apparatus hereinafter described and illustrated in the accompanying drawing; inx wlii;ch

Depending from the un; der side ,of the bar lO lslja heel-engaging member 14 secured place by screws 16, 1'6 passingvertically through openings in the bar and being. threaded into' t he e age ing inember. This member is further posi tion d', by 'a tongue and gnoove 18 formed in it and in itli underside of the barf-1a the member 14 is "a heelirreceiving cavityl20, .open at ,its front" and having: its I upper portion of suchdimensions that a heelrnay be posi I surface 22 curved both vertically and horizontally to correspond in contour to the enlarged portion of a heel, illustrated at .H, between the heel-seat-end and the reduced neck. The heel is shown as provided at said heel-seat-end with prongs or attaching devices it. Since, as the heels vary-in size and style, the dimensions of this enlarged portion change somewhat, though not very greatly, there is preferably applied to the surface 22 a layer of yieldable material 26, which may be rubber vulcanized to the surface 22, or felt secured in place by an adhesive. This lining conforms under pressure to the contour of the heel with which it contacts, and thus allows :the proper action of the abutment upon a wide range of heels Without change in :the member 14.

The flack or work-support 28 is mounted, as in the patent previously mentioned, for moyement nerticailly, under the influenee of power mechanism, toward and from the engaging \member 14, and also is movable horizontally by the operator manually to carry the jack from the worksreceiying position to that in which tilt is -operated upon, and the IIGRZGISG. In :this movement into the operating position, the initial relation between the work and the heel-engaging member 14 may be determined by a back-stop 3O annanged for engagement with the counterportion of .a shoe S, .caimied by the jack 28, to which a heel is to be attached. 'llhis back-stop is preferably adjustable, it hay.- ing, extending :reanwardly from its upper extremity, a horizontal screwqportion 32 guided in the frame 0f tithe machineand having threaded upon it a nut 34 tturning between cheeks or abutments on the frame. This permits the ghihQlQLStQP Ito ,be altered in its horizontal relation to the heel-engaging member to position \work varying in size in th desi ed relation 1 131 0 Ris ng t am th -t pof the ja k and a ead re pec ively wi th hee -prong h hen the heel is in place .upon ,the heel-seat of the shoe, rea y fo a achmen are pr jections 36, which may e furn shed by p n ha ling heads o enlargements .38 re ting u on the t p of the jac pins a e held in ynlace by a plate 24 fi ed to jack and ha ng lr ees es which receive the heads f th pins, and cpenings ethreugh which said as ,pa .s-- Ilh QPR I' Qnd ef the pins are inclin d a 42., ith re pect to thei axes, in t e d rection in hich st e a ta ing p ongs ar to he clinch As il strated, this inclination is from the center of the heel-seat .of the shoe downwardly and u war y, "so tha the po nts of h p ongs will be turned toward the rand-crease- :and tend o increa e the c oseness with which h dge of the hee i held t th uppe Upon the top- 0f the jack, above the plate 40, is a h r izonta plate 44 hailing openings which the pins enter. Between the

plates

40 and 44, and encircling the pins 36, .are helical springs 48, which yieldably hold the plate 44 with its upper shoe-supporting surface elevated above the inclined ends 42 of the pins. The upward movement of the plate 44, under the influence of the springs, may be limited by screws 50, which pass through openings in said plate 44 and are threaded into the plate 40. Counter-bores 52 in the first-mentioned plate receive the heads .54 of these screws, contact between the screw-heads and the bottoms of the counter-bores limiting the travel .of the plate 44.

In attaching a heel H to the shoe S, the proper relation between the elements may be first determined, and openings pricked in the heel-seat to receive the ends of the prongs h. The operator then places the shoe upon the jack, which is in its outer position removed from the engaging member '14, with the insole at the heel-seat resting upon the :plate 44, and inserts the prongs in the prieked-openings. Now the jack maybe carried into the operating position, as is illustrated in Fig. 1 of the drawing, the space between the jack-top and the pressure-resisting member 10 being such that the posi tioned heel may enter the .cavity 20 with its enlarged surface in proximity to the yieldable lining 26 @of the abutment-surface 22, movement ,of the jack and shoe being limited by the back-stop 30. Upon the treadling of the machine by the operator,.the jack rises under the influence of the power mechanisrn, and, the heel being held against movement both vertically and horizontally by the engaging ,member 14, ,the prongs h are forced through the heel-seat against the inclined surfaces 42 of the pins 36. The resistance to compression offered by the springs 48 is sufficient ,to at this time preirent the ppr ach f the pla s 4 and -4, so that before the heel-seat of the shoe and the surfaces 142 -move toward .each other, the points of the prongs are turned outwardly and then ,upwardly the inclined surfaces and the adjacent walls of the openings in which they (operate, putting them in the corect itelatiq iit e te the 6 f linc ngi1lhe1. l1eat ac ing press re O tiI 1- 1 g,l B spring are icempre'ss d, nd t uptu ne points ,of the prongs are carried through the sole a the side teward the andh ease, and are clinched in said sole.
