This invention relates to improvements in shoes and more particularly to heels and heel attachments thereto.
'One of the objects of this invention is to provide a simple, efficient and inexpensive heel lamination for the purpose of building into the "heel shock-absorbing qualities as well as tread resiliency which will be effective to impart to the steps taken by the wearer of such shoe a springiness and traction comfort which would not exist otherwise.
Another object thereof is to provide a shoe heel with an attachment thereto which provides comfort in walking, which absorbs all shocks imposed on the wearers foot in walking, and which definitely imparts to the shoe better traction qualitieedue to equalized resiliency and counterbalanced heft.
increase the efiectiveness of the same for better traction purpose.
A final object thereof is to provide a resilient mounting to the .under surface of the 'shoeheel so shaped and arrangedand sooperating as not only to enhance better traction on the; part of the shoe wearer but also to effectuall absorb all shocks and cushionallimpacts occasionedby the prolonged walking or standing of the shoe wearer,
whilst improving upon his posture in so doing.
With the above and .other objects in view, my
invention consists in the combination, arrangement and details of construction disclosed in the drawings, and then more particularly pointed out in the appended claims.

Figuret12 is :a plan view of a washer.
In the drawings, which are merely illustrative of my invention, 1 disclose the parts of my invention; The shoe is broadly designated A, having the leather bottom sole B to which is attached the usual heelportion 10. The heel portion ID will be made somewhat thinner than usual because it will have in surmounted relation in contact with its under surface a lamination I2; the heel has the 'usual front and concave edge H and the lamination I2, being shaped to the same outline as the heel also has the same concave recess l3, which registers with recess 1 l, as shown in Figure 1.
In one form of my invention, illustrated in Figures '1 and,2 I showthe upper surface of the lamination 12 (formed with a counterseat l4 shaped similarly to that of the lamination so that there may be snugly seated therein a metal plate 15,
.flush withiits upper surface, which metal plate wilLconta'ct the under surface of the leather heel til! at the same time other ,parts of the lamination do. As a means of attaching the lamination to the .heel I take elongated nails .25 and drive them home through lamination [2,metal plate |5,, shoe heel J0 an'dfsole B of the shoe. The heads -21 of the :nails are countersunk into the lamination l2 zby .proj'ectin'gxinto c'ounterseatsi l found therein while the .nails enter holes .25 therein,
' Theilamina'tion may be composedof any suitable material known'in the shoemaking, art, according 'toythewea'ring sturdiness required, preferably not rubber. Thehe'el, before it is secured uponthe shoe proper is formed with .a centrally disposed series of semispherical cavities 18 such that their largestdiameters open out from the underside.thereof,.remote from the shoe upper.
The lamination i2 is alsoformed with a series of semi-spherical openings whose largest diameters 22 open but of the upper surface thereof and whose lesser diameters 23 open out from theunder surface thereof, as 'fully disclosed in stubs Figure 9. An annular recess is formed between the wall of each cavity and the adjacent surface shown in Figure 9 the lamination I2 is formed '1 marginally thereof with a series of cylindrical tiny sockets 24 opening out from the under surgame ' them in place.
the under surface of the lamination I2, these tread elements cannot work loose and become displaced from these semi-spherical openings. vulcanization may be resorted to to further hold After the lamination is attached to the heel, in the manner already explained, it will be seen that the outer terminals of the fin 28 and recessed portions intervening between them will be the parts that will make contact firmly with the surface the shoe wearer is engaging in walking or standing, and in order to en- "hance and equalize as well as counterbalance the face thereof, which sockets communicate with holes which opens out of the upper surface of the lamination and communicate with the large area counterseat I4 therein also on its upper surface. The lamination, after being placed in contact with under surface of the heel, receives the long nails 26 which are driventhrough counterbores 25 of the sockets, so as to pass through washers 20, which underlie metal'plate I5,.:and extend into the shoe heel lflproper, the heads 21 of these nails being snugly received into the inner ends of tiny sockets 24 of the lamination l2; This firmly attaches the lamination upon the shoe heel. Before attaching the lamination, however, to the shoe heel there will be lodged in both the heel and lamination the complemental'resilient means which are to serve both as shock-absorbing cushions as well as resilient tread elements for the shoe heel. .In Figure 10'there is shown a globular part, being a rubber semispherical body I6 formed with a central semispherical bore ll therein; in Figure 11' is disclosed a'rubbersemispherical tread element I9 to cooperate with the cushion shown in Figure 10, which semispherical termost plane ridge 28a. of the tread elements are reached. It is obvious that better traction is had, better antiskid bearing between the shoe and the sidewalk it treads on by formation of the fins and recesses, especially when walking is done on snow, ice, etc. The radius of each rubber cushion I6 is greater than the thickness of the heel ID, that of tread element I9 is greater than the thickness of lamination I2.
The semispherical rubber cushions I6 are taken and-snugly laid in the cavities I8 of the underside of heel I0 ofthe shoe so they project with portions D beyond the inner side of the heel and have their base portions flush with the other side of heel ID. The series of rubber tread elements I9 are then taken and the'elements are inserted into the recess openings 22 of the lamination I2 in such a manner that their semispherical l9a will project through corresponding openings N formed in the metal plate I5, into the semispherical bores I! of the rubber cushions IS. The base. portions of tread elements I9 abut the under side of metal plate I5. Abutting the upper side of these plates are the base portionsof the rubber cushions I6 whereby their peripheral portions E project above the upper surface of heel Iii. Due to the fact that the major radial portions of the tread elements I9 are seated in the recesses 22, and the minor portions thereof project beyond at the same time.
traction imparted to these rubber tread elements and to improve the wearing qualities of the lamination to which they are attached, I form marginally ofthe lamination so as to skirt these said tread lements a plurality of spaced apart semispherical skids 33 which are rounded in shape and formed with similar fins and intervening depressions already noted. 'All of these semispherical skids, large and small contact-the undersurface which is engaged by the heel of the shoe; all However, knowingthat one side of'the heel will ordinarily wear out faster than the other I have multiplied the number of tiny skids33 on the left side of the heel lamination I2 with relation to the number providedupon the right side thereof, as shown clearlyin Figure 2, which also has the effect to steadythe even tread of the rubber tread elements so the heel makes contact with the roadwayunder an even keel most of the time. 1
In order to reinforce and increasethe life of the semispherical rubber tread elements I9 I may provide therefor dish-shaped metal liners 29 formed with base flanges 39 as shown in Figure 5. In mounting these liners,. in position, they are seated snugly in theopenings 22--23 of the lamination with their base flanges countersunk therein as illustrated in Figure 4. This having been done, semispherical rubber elements I9 will then be seated in them snugly. Whether these elements I9 are seated in thelinersor not; itwill be seen that at the inner planes of the grooves'or depressions intervening between .thefins .28are shoulders 32 disposed in a planeat right angles with respect to their stems I9 these are the points where compressibility of the tread elements have aligning holes R in them in whichvulcaniz ing material may be poured hot :as' a means. of homogeneously uniting all of the'rings. :iAsshown in Figure 4 these rings are graduated in diameter towards the outer end of the tread element I9 the lowermost ring of least diameter is formed fiat as at S, the uppermost ring PII- offlargest diameter carries the semisphericalistud I'9a. This composite tread elementis shown seated in thec'onicalliner3fl. 77.1.17.
'From the foregoing it is obviousthat there is provided a shoe heel adapted to Withstand rough usage, severe impacts, and unequal wear. When the nails 26 are driven through the heel I0 into the shoe sole B, it presses the heel and this in .5 marshes i the p fqtrudineihds of the semi- "sp erical cushion ;-elehi ents ER: against the shoe sole so'here direct resiliency is felt. The shoe wearer equipped "with my invention 'on the heels *o'f'the'shoe' assumespa better posture whether stai ding or engaged in locomotion because the "multiplicity o'f closely contiguous tiny skids 33 "formed on the "left side of the heel, cooperating with the. relatively larger anti-skid tread elements 1 9jimpartfjto the heelan equalized, counterbalanced feifect resulting in no drag upon any part of the heel which would promote uneven wear, 'or' cause uneven weight tobe applied. by the foot muscles with respect "to others, "ngtoinconvenience the shoe wearer and en ta ngjf'aultyposture. 'l-ilso walking, should th'e ove'l h'eel encounter ice, snow for irregulari- Tue inthe pavement'for walking surface, 'thegrip of the heel will be firm and'steady resilient, be-
"cause ofjthe'groove'd rubberconstituency of the skidsanrl tread elements. Theheel lamination willg ive yieldably, and the rubber tread elements 19, under pressure of the weight of the wearers feet, will mash the fins 28,-an'd peripheral upper portions of cushion elements I 6, between the fins .d'irt, packed snow particles and foreign particles thatbtherwise 'mi'ghtbecom'e embedded into the rubber elements themselves; "and these elements 'inay'with some degree of frictionalso'rotate in their heel bearing'sfdu'eto studs [9A being lodged in the. rubber 'cushionsin the heel; in pressing back on these tread elements, they dilate in openings 22-23, causing rubber studs 19A to enlarge which squeezes rubber cushions 16, which exert 'a shock absorbing action on the shoe sole B. Any
part of the assembly of coacting rubber and non rubber but pliable material such as leather or composition matter which is relatively thin and separated from adjacent surfaces may effectively be vulcanized so as to -fill 'all'voids with cement rubber and otherwise brace these thin spots.
I do not intend to confine myself to the exact details of construction set forth and illustrated herein but intend to cover all variations falling within the purview of the appended claims.
