SPECIFICATION forming part of Letters Patent No. 728,751, dated May 19, 1903.
Application filed April 28, 1902. Serial No. 105,097. LNo model.)
To all whom it may concern: 7
Be it known that 1, CHARLES E. McKENNA, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented new and usefulImprovements in Heel-Plates, of which the following is a specification.
My invention relates to new and useful improvements in shoes, and relates more pariicularly to the heels thereof, the object of the invention being to provide a detachable wear-plate for the heel which may be readily replaced or removed when desired.
A further object is to so construct the attaching means of the plate that said plate will be firmly held against the heel and accidental displacement thereof prevented.
With the above and other objects in View the invention consists in providing a plate adapted to be inserted into the heel and to be engaged by a tongue and a retainingspring extending at an angle from one end of a heel-plate. The tongue is adapted to hold the heel-plate against lateral or longitudinal displacement, and the spring serves to retain said plate in contact with the heel.
The invention also consistsin the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which.
Figure 1 is a plan view of my invention in position upon a shoe-heel. Fig. 2 is a central 1ongitudinal section through the same. Fig. 3 is a detail view of the retaining-plate, and Fig. 4 is a similar view of the heel-plate.
Referring to the figures by numerals of reference, 1 is a shoe-heel, within which is secured a retaining-plate 2, having apertures 3 therein for the reception" of securing-nails. One edge of the plate is adapted to extend from the forward or straight edge of the heel and is provided witha downwardly-turned flange 4, which is located at a slight distance from the heel edge, for the purpose hereinafter described.
That portion of plate 2 between the flange 4 and the heel edge is provided with a slot 5, formed by striking up a lip 6. The lower edge of the flange is recessed adjacent to the center thereof, as shown at 7, and a head or shoulder 8 is formed at the inner end of the recess.
The heel-plate 9 may be of any desired form and material and may, as shown in the drawings, be provided with pointed lugs or projections 10 for preventing slipping or can, if
desired, be secured in any suitable manner upon a thickness of leather or other material.
The heel-plate is provided with a central lonof the heel-plate and is equal in length to the slot 5, before referred to. It is also equal in thickness to the distance between the flange 4 and the heel edge. It is therefore obvious that when this tongue is inserted in rear of flange 4 and into the slot 5 the heel-plate will be prevented from moving laterally or longitudinally upon the heel.
A spring-strip 15 is arranged within the slot 11 of the heel-plate and is secured at one end to the lower surface of. the angle-plate 13. The opposite end of the spring is curved upward over the tongue 14 and forms a catch 16, having a projecting arm 17, whereby the same may be readily pressed or drawn outward. This spring-catch is adapted when the tongue 14 is in position back of the flange 4 to engage the head or shoulder 4 of said flange and lock the tongue and its heel-plate securely in position upon the heel. It will be understood that said plate can be readily detached by pressing upon the arm 17, and thereby disengaging the catch from the shoulder 4.
In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make all such changes as fairly fall within the scope of the following a heel-plate, a tongue extending therefrom at an angle and adapted to engage the slot, and
a spring-catch extending from the heel-plate and adapted to engage an edge of the slotted plate.
2. The combination with a heel having a plate therein and a slotted end to the plate extending from the heel, of a slotted heelplate, a spring-catch secured in the slot of the heel-plate and adapted to engage the slotted end of the plate in the heel, and a tongue extending from the heel-plate and adapted to extend into said slotted end.
3. The combination with a heel having a plate secured thereto and provided with a slotted end extending from the heel and formed with a flange having a shoulder, of a heelplate having a slot therein, a spring-catch secured in said slot and adapted to engage the shoulder on the flange, and an angle-iron secared to the heel-plate and provided with a CHARLES E.
