, invention,Ifrlates toheel coatingand is illustrated' as embodied in a machine for coating heelsbydipping them. A very large percentage-of` Womens shoes at the present time are provided with wood heels and it is customary to lcover thesexheels either by. painting or lacquering them` or else by 4sticking, on a coverof thin material whichwmay beiof leatherifor fabric and. which usually matches the upper ofthe shoe. Obviously the cover rapplied tothe 'heel must adhere .very tightly itY will noty become separatedv during Wearrfof the shoe, and it is customary to apply' adhesive tothe vcurved periphery of the heel' at least andusually to al portion' of kthe vattaching-suriacefandthe Whole of the breast surface." :One convenient iway of 1 applying adhesive, hereinafter called cement for` convenience, is by'dipping the heels and then allow'ingthe surplus to-drain'of. l Preferably the Whole ofthe attachingv surfaceshould 'not be coated because it is customary to mark the-'size and style of the heel on thisfsurfaceand'the liquid coating mayk obliterate some of these marks. lThe WoodV utilized for making-1 heels' for shoesis rkiln dried' andv contains'v a considerable quantity Aof air which should be allowedto' esoapeduring the periodwhen the heels are immersed in the cement soi that no bubbles will form in the'coating of the heels after Ywithdrawal;- -Furthermore, -in view` of' the viscous ,nature of n'the' cement,

great care must be utilized in draining: the "surf `-plus cement from the heels inv orderr'that 'the coating applied may be uniformcvertli surface :of the heel and-Without Wrinkles orA sags.l

' With aview'to satisfying-these and ther'requirements, one object of the present inventlonis to provide an improved machine for dippingY heels lby means of which a uniform coating inaybe'applied vwith av minimum ofa care upon the part-oi' of the attaching surface below theirestoftlie fheei, and? that the desired object' m11 also `be "obtained Hwith greater certainty yiffthefheels- 'are Yv'vitlidravvn from the bath vofcementvery graduv'ally'. feature :of the invention', therefore; fresides'inv 'a heel support for vuse with ra heelldipping ,jtheba'se 22.

hydraulic elevator for raising the containerx and controlling its downward movements to regulate the speed of withdrawal of the heelst'ffrm the liquid. To raise the container, there has been provided a pump 34 includingapistor'ili,adamted` .to be actuated by a foot treadle 3Min-Th 1.001? treadle is pivoted on the base 22 and connected by means of an upright rod 40* to a'ringeshaped rocker 42 the other side of which is 'pivotedg'to a piston rod 44. A spring 46 surrounding the rod 40 holds the'treadle normally'.` inelevatedposition. Hspring-pressed, `one-way`rrlr valve `4B fpre'- vents back flow of the liquid from thee-chamber 32. Access to this valve'and adjustx'nent ofthe spring pressing againt the valve is` providedlbyel threaded plug 49.. kAbove the pumplchamber 34 is a reservoir 50 holding' a supply'fof---liquidf-such as oil. The pump piston36, as'r illustrated", comprises aV plate or spider 52 having angularfpassages 53 anda cup-shaped'packing 5,4 secured toa washer 55 loosely held on the pistonvbya rigid plate 56.attached to the :end of therpiston rod 44 withinthe cup-shaped packing 54.

When it is desired to lowerfthe container 26 to withdraw theheels from the cementglthe' treadle 38 is depressed tobring the piston=36 and-especially the plate k55 against thevalve 48, Ias'shown4 in Fig. 4, and allow theoil to returntothe reservoir 50 through the passages 53...v Theispeedoiwth- -drawal of the heels is controllediby regulating the degree to whichthe passages 53 Vare openedand this, in turn, is regulaterby means of a stop 60 which coacts with ythe .rockerring 42 when A.the treadle is depressed to limit the downward miovement of the piston 36; `:.Thisstop screw -SIIis threaded in a removableblock applied to the base,

`which block performs the additionalfunctlon of a key for the Aplunger 3|)4 to-.prevent rotation; of the support 28 with respect to'thefnase 22.`

It is quite immaterial :whether We'areY dealing with a Cuban heel Ill=or a'Iouis heel I2'.` The important thing `is to position the. heel in inclined, and preferably in an inverted'position and such that none of the plane surfaces of the heel-are horizontal.` vThe heels. are .skewed-.with respect to the rack I4 so that one corner of the attaching surface is lower than Vthe rest of the heel to permit '1 the cement to drain more readily from this corner.

.The rack I4 comprises a pluralityof `cross-bars 62 in which are secured inclined, upwardly directed, retaining members 64 (Fig..3) having a sharpened point or prong SI5-adapted to be -driven into the heel. Surrounding these retaining members 64 are blocks 58 each vhaving-"afperiplleral contour which is generally U-shaped likeafheel (see also Fig. 1) and which are of compressible materiaL such as sponge rubber, which are'backed up by washers Ifill andare provided with upstanding peripheral rims 12 substantiallyieven'with the ends of therprongs and adapted to conta c't" t'ightly with the attaching 'or cup .surfaces l4fof4 thelheels, thereby to protect thefcentralportion of :'efachof these surfaces rfromthe applicationof '75 This, ergenis .the ',Sge-aeeisirl; matigen.- .sie

heel from being covered with cement and hence partially obliterated.

In the use of the machine, the operator will take one of the racks I4 on a bench which, if desired, may be provided with angular ribs (not shown) to back up the bars 62 of the rack and the retaining member 64 thereon and to permit the operator to secure heels on Vthe yrack by tappingfthe'm lightly againstthe prongs 6 6" with the heels extending heightwise in thegeneral direction of the prongs. In this operation the skewed position of the heels shown most clearly in Fig. l willbe-linsued by reason of the heel shape of eachv ofthe sponge rubber blocks 68 which substantiallycomplements the form of a characteristic featurekfof the heel, here the peripheral contour of the attaching surface. These blocks, then, -will guide the operator by touch in orienting the heelsand impel him to position the correspondinglyshaped attaching surface of the heel in coriresponding' position on the blockl At the-same -time, a heel presented to the holder will be guided by touch to a position with its axissubstantially aligned with the'axis. of -a prong as the cupped :attaching `surfaceof the heel is brought into firm contact with the inclined ytop surface of-fthe rub- --ber .block 68. A light tap of the hammer will then Lbe s'uiiicient. to impalethe heel on the prong-66 vand theupstanding rim 12 of the blocks. 68 will serveto .position the.,heei. in inclined,a inverted iposition on the rack- :withnone of its plane sur- .faces horizontal andwith one. corner of the at- 'caching surface below, the rest of the heel. Depression-of the treadle 38 to operate the pump 34 `Willlthen serveto raisethe vcontainer 26 to immerse theheels.,The containeris held in elevated position bythelvalve 48 and will be'fretained .there-for the desiredperiod of approximately three minutes. After this, the operator will step on .the treadle 38 and force it down as far as is permitted by, the stop screw 60, thus opening the valve 48 and allowingthe liquidinrtherchamber .32to flowoutslowly through the passages 53 vunder.therweightwof the cement container and vattachedparts.V This relief may be `-rnade as slow "orasrapid asis desired, thereby tocontrol the Vspeed of withdrawal of the heels from the liquid. `If thegheels arewithdrawn. too fast, the cement Aonltheslirfaces, of the heels is likelyrto dry in ridges,` whereasif they `are vWithdrawn slowly ltherewill be plenty Vof opportunity for the surpluscementto drain ofi as they graduallyemerge from thefliquldv Having t hus described my invention, what .I ,claim as new and desire to secure by Letters Pateiiitof tl'ieg United LStates. is: Y
