HEEL TOP LIFT.

Specification of Letters Patent.

Application filed November 7, 1912.

Patented Nov. 4, 1913. Serial No. 730,041.

To all whom it may concern:

Be it known that I, ALFRED LENDGREN, a citizen of the United States, residing at Corning, in the county of Adams and State of Iowa, have invented certain new and useful Improvements in Heel Top Lifts; and I do hereby declare the following to .be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to boots and shoes and it more particularly relates to an improved form of heel top lifts.

An object of the invention is to provide a device of the character stated, which may be secured to the heels of athletic shoes and of rubber boots and shoes to prevent them from slipping.

Another object of the invention is to pro-. vide a heel top lift which comprises a body of comparatively soft and malleable material and a removable and interchangeable flanged member of somewhat tougher mate rial, such as malleable steel, or wrought iron of a suitable alloy.

Another object of the invention is to provide a removable and replaceable anti-slipping flanged element, having a wedgeshaped securing element whereby it may be quickly and easily removed and replaced.

Another object of the invention is to provide for protecting the nail heads with which the device is secured, and at the same time providing for easy access to the nail heads, when it is. desired to remove the latter.

Vith these objects in view the invention consists of the improved construction, combination and arrangement of parts of a heel top lift, which will be hereinafter fully described and afterward specifically claimed.

In the accompanying drawings, Figure 1 is a perspective view of an athletic shoe in inverted position,-Fig. 2 is an under plan view of my improved heel top lift, Fig. 3 is a fragmental sectional view illustrating-the device applied to an ordinary rubber shoe heel, and Fig. 4 is a vertical sectional view through a simplified form of the/device which constitutes my invention.

In these drawings,'in which similar reference characters correspond with similar parts throughout the several views, the'shoe heel in Fig. 1 is designated by the numeral 5', the ordinarily roughened sole of which" the elements 17 and 8 is 8 of my improved heel top lift are prefershoe is designated 6. The body 7 and flange ably secured to the heel 5 by means of nails 9, the heads of which are seated in grooves 10, which extend in approximately parallel relation to the periphery of the heel top lift. Exteriorly of the groove 10 is a series of alternating lugs and recesses, 11 and 12 respectively, said recesses with the groove 10. The middle portion of the heel top lift may be provided with intersecting grooves 13, which separate a series of bosses 14, which provides an anti-slipping or roughened surface which auxiliates and eventually substitutes the raised portion of the bosses 11. After continual use, bosses 11 may become worn away, so that the bosses 14 are exposed to a greater extent than previously, thereby substituting the bosses 11. The body 7 is preferably concaved, as indicated at 15 so that the peripheral ortions thereof fit snugly upon the heel of t e shoe, even though the heel has become slightly convexed because of wear. The upperside of the body 7 is recessed or ofl'set as shown. at 16, so that when said body is fitted on a shoe heel, an aperture isprovided between the forward edge of said body and the adjacent bottom surface of the heel. WVithin this -recess 16, may be seated the wedge shaped base plate 1 7 on which the flange 8 is formed; said flange 8 extending downward and substantially at right angles to plate 17. The forward edge of the base is provided with a rib 20 which extends approximately in front of the rib 20 is a relatively thin portion 21 which constitutes a groove when the flange 8 is in place as illustrated.

The body 7 is preferably made of malleable cast iron, while the member comprising preferably formed from malleable steel, so that the flange 8 is tougher and less easily worn than body 7..

Therefore, the flange 8 may be easily bent rearward into the groove 21 by means of a hammer or the like, so that the flange will. not mar the floor on which the wearer of the shoe walks; but, in the case of sleet, etc., when the flange is to be used, a chisel, screwdriver or other tool may be employed for bending said flange up into vertical position so that it will cut into the sleet or ice, so as to prevent slipping thereon. This feature is also desirable when used on athletic shoes, as in some athletic games the vertical flange communicating the entire distance across the said body, and

- is desirable, while in other games, it is unwhile in that bent-down or horizontal position, they may become worn to such an extent that they will break when an attempt is made to again bend them into a vertical position, and they must then be substituted by another similar member. In order to provide for quickly removingbroken plates and substituting them, I have provided for protecting the nail heads 9 by placing them in the groove 10 so that said nail heads will be protected against wear by means of the adjacent sides of the groove 10. Therefore, a narrow chisel or other suitable tool may easily be inserted in the groove 10 and forced under the heads of the nails which hold plate 17; so that the said nails may be drawn, for releasing their engagement with said member '17 and allowing it to be removed and substituted by a new one. The member 17 is preferably wedge-shaped, so that it may be quickly and easily placed in proper position, whereupon, the. nails'may be. replaced or substituted, for 'securing said member 17 in fixed position. In removing the member 17, it is only necessary to remove the three nails which comprise the front row so that the position of the body 7 remains undisturbed.

By making the flange 8 of tougher material than the body 7, the said body will wear more rapidly than said flange, so that the latter continues to project below the wearing surface of the body until the latter has completely worn out.

, Instead of making the members 7 and 8 separable, I may preferably cast or forge the entire heel top lift integrally, as shown in Fig. 4. In this figure, the base is specified 1 by numeral 7', the flange 8 being rendered tougher and less easily worn than the base 7 by any ordinar process of annealing .or tempering or the ike.

I do not limit my invention to the exact details of construction, combination and arrangement of parts as herewith illustrated and described; but my invention may only be limited by a reasonable interpretation of the claims.

I claim: 4 I

1. A heel top lift consisting of a Hat metal body having grooves and bosses on its lower side, its upper side having a forwardly disposed recess and apertures communicating with the recess and adapted to receive fastening means such as nails, and a downwardly flanged plate fitted into the forwardly disposed recess.

2. A heel top lift comprising a metal plate having a groove in its lower side and a recess in its upper front side and also having apertures communicating with the groove and the recess and adapted to receive securing means such as nails, and a wedgeshaped plate seated in the recess and adapted to be engaged by the securing means, said wedge-shaped plate having a downwardly extended flange thereon.

3. A heel top lift adapted to be fitted to the heel of a shoe and having a groove adjacent to one edge and having a flange forming a wall of the groove and extending be low the level of the lower surface of the lift said flange being of malleable material and adapted to be bent over into the said groove.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
