HEEL-BUILDING Macrame.-

Applicationfiled May 23, 1927. Serial No. 193,492. 1

tion'is the provision of means to assemble a rubber heel with its heel base, before said heel and base are delivered to the shoe heeler. In other words, instead of the shoe heeler handling three units, viz., the shoe, heel base, and rubber heel, I reduce the number of units to two, viz., the-shoe, and the completely assembled and prepared heel base and rubber heel, firmly united as a single unit;

Incarrying out my present invention, I preferably utilize a machine asillustrated in the present-application, which machine I believe to be novel, and have therefore claimed broadly herein.

By the use of my novel machine I attach the heel base and the rubber heel, firmly uniting same and preparing both as a unit for simultaneous attachment to the heel portion of the shoe instead of, as formerly,

necessitating separate and successive attachments, first of the heel base, and then of the rubber heel. assembling the heel By my invention of thus first base and rubber heel into a single unit, the same can thus be simultaneously attached, the completed heel base and rubber heel being handled as a single article and at a single operation. Furthermore, it is a much easier and simpler proposition to aline, assemble and unite .the' heel base and rubber heel while each are separate,

rather than after one of the same is attached to the shoe. Also, in their thus assembled relation,- the bufiin'g, trimmingor finishing of the'heel breast and sides and rear of the heel'is greatly simplified, without requiring the. time, delay, skill, and machinery necessary to handle the completed shoe and heel in the heel breast scouring actionf Further details of construction, advantages, combinations of parts, will be hereinafter more fully 'claimed.

Referring to preferred @nih described. and

As shown in: the drawings, my present novel machine compr1ses"a,pa1r of sideframes or supports 1 andflZ.

is not essential, as I' may'vary such number I without departing from the spirit of the invention. Y

As shown novel clamping 7 device comprlses a plate or table 15, secured to the cross shafts" 8' by vided on thetable :15, having Ja'fac'e 18 in detail in Figs.-4 and 5, my

against which the rubber heel 19, illustrated;

lever 65, with the roll 69 will move the ie vier ,65 outwardly,tourardthe edg'eof the niachh fi, also causing the leyerf66 to move outwardly toward the edge ,of themachine. against the springfiT, and toward the top hi the clamping device." One endo'l the lei-er is provided v vl h a recess 71 in which fits .a hip; I2 'hichis a psior a slide 3, said slide 73 having a slotadaptcd to slide over a scre v or the lilge 7 5. The llllpel end 76 of the slide 73 enters a slot in. the plate 15, and on upward 'ii' ovement of the lever 66, the slide T3 is also raised, thus projecting the y then lirn ly imited rubber heel and heel base from the clamping device and into a hopper or vthe lilge 77, provided therefor. It will be appreciated that at the time of this discharge of the completed unit the roller 53 of the clamping device under discussion will have contacted with the stationary cam 54, and will have ridden up on said cam a suiticient distance to allow the plunger 51 ,to be opened or spaced from the united heel and a 9 Perm h d scharg f e r be lieel and base from their guides and the plate 15. It will also be apparent from a glance at the drawings that the rods 48 pass through the reinforcing portion 62 as 'well as through the plate 15. The same arrangement of levers 65 and 66 is provided for each of the clampinginst'ruinentalities.

The springs 55 between each opposite pair of clamping devices are so inounted that they will not interfere with each other throughout their extent across the interior of the machine, the brackets 57 on each clamping device being angled or positioned to insure clearance between the various sets of springs.

It will thus be appreciated that I have devised an eatremelyefiicient, quick acting, and positive machine for the purpose set forth, greatly increasing the speed of shoe manufacture by reason of the reduction in the "number of operations heretofore 'required by the shoe-heeler. hly prese nt machine is siinple in operation, and will be readily understood by those skilled inlthe art, the operation'of same being as follows: The. operator having a plurality of rubber heels and heel bases, either coats one or both of the contacting surfaces of said heels and bases and preliminarily unites the same, or has the thus-united heels and bases delivered to him in this condition, depressesthe .fo'ot treadle 13, shifting the driving belt ll to the pulle s. and setting the machine oper t n- There pqi each su ess ve laiaPJQQdeYiQ' tea hes e to]? of he inichi faccesj ible to the operator, the operat or positions a cemented heel and base in t e" guides therefor, the plunger 5l'beinig raised by tlie'cairi-fifi, the. clamping device passi to ,the'right, viewed in'Fi'g. 1,
