4 Claims. (Cl. 36-38) This invention relates to heels for shoes, boots and other footwear and more particularly to new and useful improvements in composition heels for ladies shoes.

It is well known that resilient heels are more comfortable to walk upon and are much less tiring. It is therefore a primary object of the present invention to provide a shoe heel of resilient construction.

Another object of the invention is to provide a ladys shoe heel which is attractive and marketable in appearance and which is adapted to cushion any sudden pressure against the feet which is so objectionable in conventional heel constructions.

A further object is to provide a ladys shoe heel of this kind which is sturdy and durable in construction, and reliable and efiicient in operation.

Yet another object is to provide a ladys shoe heel of this kind which will be effective in causing a relaxing of the feet and leg muscles when stood upon and will cushion the shock on being walked upon.

A still further object is to provide a composite ladys shoe heel whereby the shock on stepping will be efiectively cushioned, whereby the ankle and calf muscles of a person using the same will be in a more relaxed condition while standing for a long period of time upon the heels.

A specific object of the invention is to provide a composite rubber and steel spring shoe heel for ladies having advantages over and above heels of rubber .and metal springs separately, the parts of which composite heel coact toward eliminating by each component of the defects of the other considered in its separate capacity.

Other objects and advantages of the invention will be apparent from the description thereof to follow taken in connection with the accompanying drawings in which Fig. l is a fragmentary side elevational view of a ladys shoe with a heel embodying one form of the present invention, parts being broken away.

Fig. 16 is a rear elevational view thereof.

Fig. 17 is a cross-sectional view taken on the plane of the line 1717 of Fig. 16.

Referring now to the drawings in detail .and particularly to Figs. 1 to 7, inclusive, showing the first form of the invention, there is shown in Fig. 1 a fragment of a ladys shoe 20 comprising an upper 21, a sole 22 and a heel portion 23. A heel 24 made in accordance with the invention is mounted on the heel portion 23 of the shoe. The heel 24 is of the so-called Cuban type comprising an outer envelope or body 25 of rubber. Embedded in the body 25 centrally thereof there is a spring assembly indicated generally .at 26. The spring assembly consists of an upper metal disc 27 and a lower metal disc 28. The discs. are circular in shape. The upper disc 27 has a flat undersuI-face 30 and a tapered upper surface 31. The upper surface 30 is also curved longitudinally defining a concaved seating surface. The lower disc 28 is fiat. Each disc is formed with four countersunk holes 32 spaced so as to form a square to receive the neck portions 33 of studs 34. The studs 34 extend radially from the discs in opposed relation as best shown in Fig. 7. The neck portions 33 may be secured to the discs by soldering, welding or the like. The discs are connected by four compression springs 35, the ends of which are sleeved around the studs 34 with their ends seated against the inner surfaces of the discs and suitably secured thereto. The studs guide the springs in their movements and tend to stiffen the same preventing the collapse thereof. The springs are preferably made of steel wire square or rectangular in cross section.

The spring assembly 26 is positioned in the rubber body 25 so that the upper surface 31 of the upper disc 27 is flush with the upper concaved surface of the rubber body 25 and is fastened to the sole 22 of the shoe by screws 37 passing through threaded openings 38 formed in the disc 27. The screw heads are covered by the inner stocking lining 38 of the shoe.

The spring assembly is embedded in the material of the body 25 of the heel preferably by placing the assembly in a mold and pouring the molten rubber forming the body 25 over the assembly so that the molten rubber will be bonded to the assembly, with a thick layer 40 of rubber below the lower disc 28 as shown in Fig. l. The rubber is bonded to the steel spring assembly in any conventional manner such as by vulcanization, the compression springs being masked during the operation.

In the modification shown in Figs. 8 to 12, inclusive, the invention is shown applied to a ladys heel 24 slightly narrower but longer than the type shown in Figs. 1 to 7, inclusive. This form differs from the form shown in Figs. 1 to 7, inclusive, in that in place of the fiat lower disc 28, there is an enlarged metal tapered body 41 which is adapted to occupy a larger area and extend further along the rubber envelope or body 25. The reduced neck portions 32' of the studs 34' thereon are sunken in sockets 42 formed in its top surface.

In all other respects, the form of invention shown in Figs. 8 to 12, inclusive, is similar to the form of Figs. 1 to 7, inclusive, and similar parts are indicated by similar reference numerals.

Referring now to the embodiment of the invention illustrated in Figs. 13 to 17, inclusive, there is here shown a so-called French type heel 24" longer and narrower than the previous types of heels described above. A heel of this shape necessarily takes a longer and narrow spring assembly such as best shown in Figs. 15 and 16 and indicated generally at 16", so as to accommodate itself to the dimensions and acute slant of this type of heel. This spring assembly 16" is embedded in the rubber envelope or body 25" of the heel and secured therein in a manner similar to the form of invention shown in Figs. 1 to 7, inclusive. I

The spring assembly 16" consists of an upper metal disc 50 similar to disc 27 of'the form of Figs. 1 to 7, inclusive, and a lower metal disc 51. The

discs

50 and 51 are formed with radially extending studs 52 and are connected by compressions springs 53. The discs, studs and springs are constructed similarly to the discs, studs and springs of the other forms of the invention, except that there are only three studs and springs, spaced in triangular formation as best shown in Fig. 17. In this form, however, the upper end of the disc 50 is formed with an integral flange 54 therearound, the flange being substantially rectangular in shape as shown in Fig. 14. The flange is formed with openings 55 spaced along its periphery for receiving the fastening screws 56. An elongated stem 57 depends from the center of the lower disc 51 and slidably mounted on saidv stem is a sleeve member 58 carrying diverging arms 59, the upper extremities 60 of the arms being turned inwardly and fastened to the rear end of the flange by welding or the like. A thick layer 40 of rubber extends below the bottom end of the stem 57 so that there is no chance of the stern cutting through the rubber.

The spring assembly 16" is embedded and secured in position in the envelope or body 25" in a manner similar to the assembly 16 of the form of Figs. 1 to 7, inclusive.

The heel 24 functions similarly to the heel 24, the arms 59 and sleeve 58 permitting pressure to be exerted downwardly at the rear of the heel so that there will be no lateral deflection of the springs 53.

In all other respects, the form of invention shown in Figs. 13 to 17, inclusive, is similar to the form of Figs. 1 to 7, inclusive, and similarreference numerals are used to indicate similar parts.

While I have illustrated and described the preferred embodiments of my invention it will be understood that changes in details might be made without departing from the principle of the invention.

What I claim is:

1. A composite heel for a ladys shoe comprising a body of rubber and a metal spring assembly embedded 4 therein including a pair of upper and lower discs, a plurality of compression springs interposed between said discs, the upper disc having a curved upper surface shaped to conform to the shape of the sole of a ladys shoe, said upper disc having threaded openings to receive fastening elements for fastening the heel to the shoe.

2.
