Application filed January 28, 1921. Serial No. 440,709.

oll (lhio. have inrvntvd vvrtain new and useV lul lni|no\'vnunt in ltvsilivnt. llvvls. of whivli thv following is a lapvvilivation.

'lhis intention rvlatv l to elastic cushion heels and lil'ts and has as one ol' its objects to provide a heel or lil't which nia)l he readily applied and evurvd in place` usually hy a single fasti-ning vlvnivnt Auvh as a nail or svrvw and whivh when applied will not liv lialilv to livvoniv displavvd.

,Another olnjvvt ol' thv invention is to so vonatruvt thv article that thv saine. when in the torni ol' a litt. will snugly lit thv `shoe hvvl and he prevented l'roni tlvxing awa)v troni thv hvvl notwithstaluling thv employ invut olI hut a singlv fastening vlvnivnt.

lurthvr olijvvt ol' thv invention is to provide a hvvl or litt so vonstruvtvd that it will vll'vvtually ahsorh ehovlts and will cushion thtl inipzivt ol'v thv hvvl with thv ground surl'ave.

A\not.l|vr ohjevt of the in\vntion is to provide a novel aevuring invane for holding the litt in plavv upon thv shoe livel and prevent ing thv litt troni turning ahout thv evi-tiring elvinvntas a pivot.

Alm thv invention has a further olijvct to so torni the tread lave of the litt as to vtl`evtuallyv provide against. `alipping on wet pavvruvnte and other Slippery y"urlavvs,

Figure h is a vertical front to rear sevtional rivw on the linv 8 8 of Figure T;

ln the :levoinpairving drawings the prinviplvy ot thv invention are illustrated as vnihodied in the vonatrnvtion of an elasti or resilient cushioning heel lit't but it Wil hv understood that the invention is not liniitvd in this respeet but mav eqn-all)v as Well lind embodiment in a heel as a unit.

In the drawingb the numeral l indicates in general the hotly ofthe lift and this hotly is oll the usual marginal contour and` while transversely straight, is longitudinallyv curved throughout its length in a front to rear direction. The tread face ot thv hotly is indivated hy the numeral 2 and the at` tat-hing lave b v the numeral 3. they fave .2 living convex and the tace 1l concave in the initial condition ot the lift although. when thv lii't is applied to the shoe heel. indivated in thv drawing hir thv numeral 4, thv litt will liv euhstantiall)Y tlattened out by thv pressure exerted h v the anchoring plate which will prvsvntl)v hv dvsvrihed.

ln securing thv lift to thv ihoe heel l inaliv use ot an anvhorng plate suvh as that lehown in Figures t to t' inclusive` or the plate lehown in Figures T to t) invlnairv. 'l`hv plate is indivatvd in general h v the nunivral 5 and the saine voinpi'ises a hody portion t provided venti-ally willi an opening T t'or thv liassagv of a securing vlenient such for vx anlplv as a nail h or a svrew` either adapted to he ilrirenthrough the lift and intothe shoe livel 4l. lllarginall)v the hotly (t is. provided wit iaptuevel'tain ot whivh are. indit'atvd hy the numeral l() and anotherhy the numeral l1. and thv plate is. in the vonrsv of nianufavture of the article` elnheddvd in the lift hodv l in auvh manner that the spurs 1t) and lil will penetrate the said hotly and projevt at their pointed entering ende 12 lgeyond the uttwhing tavv ot' the hotly. The series ol' apural is voncvutriv to the opening T in the liody t' ot the plate and all ot these spin-510 ale locati-tl in a vominon arc. However the spur ll is spavvil from the opening 'i prefvrahlv a grvatvr distance than an ole the 4wurI lll. aud the sevuring plate is so amenihlvd with thv lift that thisl spur t1 will pvnvtrate the hotly ofthe lift nearer the rear side of the said body than any of the spurs 10. As stated above. the entering ends 12 of the spurs 10 and 11 projert beyond the attaching' faee of the litt. so that when the lift is secured to the heel by driving the nail or other securing element ti into place, these ends of the said spurs will also be caused to enter the heel 1, and thus, while the element serves primarily as a seeuring means for holding the lift in plaee upon the heel, the spurs 10 and 11 serve this purpose to a oertain extent but primarily are intended to prevent rotation of the lift about the securing element so that notwithstanding the use of but a single seeui'ing element,y the lift is Securely held in place. By reference to Figures 4 and G it will he observed that the anrhoring plate is euri ed eontinuously in the front to rear direct-ion or in other words longitudinally from that side of the body of the plate at which the spur 11 is located to the diametrieally opposite side of the plate. The plate however is transversely Straight as will be observed by rel'erenee to Figure 5. Furthermore the plate is resilient and it will be understood that inasmueh as its curvature corresponds substantially to the curvature of the lift body in which it is embedded, the plate will serre to firmly bind the altar-hing l'aee ot the said lift, body against the shoe heel when the securing element S is driven into place, the anchoring plate being at sueh time sprung, tonearly flat condition and the lift itself beingV likewise changed in form.

In order that the attaching l'aee of the lift may snugly seat against the lower face ol the heel 4 of the shoe and in order that the lift may possess maximum ellieieney as a cushioning means`r the said face of the lift is formed with a depression 14 bounded by a beveled opstanding marginal portion l5 extendimtgr entirely around the margin of the, said face, and this face of the lift is also formed in the depression 14 with an up standing bea.; 1G of a height substantially equal to the raised marginal portion 12 and conforming; in outline thereto, the bead. 16 beiner -surrounded by the raised portion 15 and being designed to contant or eontaet at its upper edge the low-e1` fare of the heel 4i It will he obewrred by referenee to Figure 2 of the drawings that the beveled opstanding marginal portion 15 at the opposite Sides of the lift body is of gradually in reusingr height and width toward a point substantially midway between the front and rear ends of the litt so that when the lift body is liattened out at the time of' applieation to the shoe heel` this portion whirh is of increased dimensions will be stietehed out` or elongated and will` when the lift is entirely flattened and attached, be of substantially the same dimensions as the remaining portions thereof. and thusI tinI said npstandA ing;f marginal portion l5 will snugly Contact the fare ofthe shoe heel al all points in thtl length of the former.

1n order to prevent slipping' on wet pariments or other slippery snrt'ares. the tread face of the litt body may be formed with a' number .of flutes 1T which extend substantially radially from the rentral portion to the margin of tlnl body. These tintes 1T are gradually increased in width from their inner to their outer ends. and their lares are preferably transrersely ronvave and they are `gradually im'reased in depth from their outer to their inner ends. as elearly shown in Figures 1 and of the drawings. A\lso the lares of the flutes are disposed at a slight angle to the tread surface of the lit't as a whole so that abrupt fares 1H are provided extending along one marginal side ol the eoneare tace of eaeh llute. ln order lo l'ur ther prevent slipping of the heel on slippery sui-'lares` it is preferable that the lai-e 2 be formed with an npstanding,r rib 1S of substantially annular forni whit-h rib surrounds a depression 2|) and at (he outer side oi which the inner ends ot the flutes 17 terminate.

The ani-boring plate shown in Figures 7, H and l) oi the drawings is ol' the same gen eral Contour as'the plate shown in Figures A'L' .3 and G and comprises a body portion 2l corresponding to the body vportion and formed eentrally with an opening 22 eorresponding to the openingl 7. Also tbe body portion is provided at its margin with spurs Ql eorrespondingr to the spurs it), and a spur 24 corresponding to the spur l1. ln this modified forni however the. body portion is preferably provided with a number oi' openings 2.1 supplemental tothe opening' 22 so that more than one sei'urinplr nail or seri-w maybe employed in attarhing the lilt to the shoe heel. Also in this` modified struc-ture it. is preferable that a number of spurs Qu he etanlped out from the body portion il in the .series surroumlingir the opening 22, these spurs beine)r adapted to be embedded in tin` heel lift at the time oi' mamifaeture, and as best shown in Figure Si oi' the drawings.

As stated, it is preferable that the beveled marginal portion l5 of the attaehing lar-e ol the lift be formed thirlcer at the sides of the lift than at the breast and rear of the litt so that when the lift is flattened out in applying it to a shoe heel thestretching stress to whieh this marginal portion is Suhjeeted, and the resultant elongation ol: the portion at the sides of the lift will not negative a snug engagement of the attarhing fare against the lower sido of the Shoe heel.

It will be understood that the lift may be prodnred devoid of any anti-slipl'iing devices upon its tread face' and that therefore the illustration of the flutes 17 is intended to llO merel)Y disclose one manner in which the lift may he provided with anti-slipping surfaces. 1t` will also be understood that various other rhanges may he made without departing from the spirit of the invention.

Having thus desi'rihed the invention,y what is elainied as new is:

yA heel lift eomprisingr a resilient member, an annular rib, delining a central suction area upon the tread faro ol' said member and provided with a ventral aperture adapted to receive a securing element. for the resilient member; radial flutes on said tread face, said flutes extending from said rib to the margin of Said member, each of Said luteel having a slxhstantlially perpennrlieulur side and a concave side eonneeting the base of the perpendicular :side with the apex of an adjacent illite, thereby lorniinlr a sharp edge therewithj and the concave sides of all of said flutes lacing in the Same direction, eirenmferentially,

.In testimony whereof I affix m i signature.
