RICHARD GERLAOH, OF FRANKFORT-ON-THE-MAIN, GERMANY.
HEEL FOR FOOT-GEAR.
Specification of Letters Patent.
Patented Dec. 29, 1908.
Application filed August 7, 1907. Serial No. 387,471.
To all whom it may concern:
Be it known that I, RICHARD GERLAcH, merchant, a subject of the King of Prussia and German Emperor, residing at Frankfort-on-the-Main, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Im rovements in Heels for Foot-Gear, of whic the following is a specification.
This invention is an improvement in boots and shoes, and relates particularly to the heels thereof, and its object is to provide the heel with a detachable and attachable lift, or plate whereby the height of the heel can be varied, and its wear greatly enhanced.
The invention consists in the novel means for detachably attaching the plate to the heel, as hereinafter described and claimed.
In the accompanying drawing the invention is exemplified.
Figure 1 is a plan view of the holding plate for the removable lift; Fig. 2 is a similar view of the holding plate attached to the bottom of the heel; Fig. 3 is a section on line AA Fig. 1; Fig. 4 1s a section on line B B Fig. 1; Fig. 5 is a section on line 6-0 Fig. 2; Fig. 6 is a section on line DD Fig. 2; Flg. 7 is a vertical section of a heel with the removable lift in position.
The invention comprises two holding plates 0, (1, respectively embedded in the removable lift a and the bottom of the heel I). Said holding plates have horizontally projecting spring tongues e, f, respectively, which tongues are arranged to engage as shown, while said holding plates are covered by layers of material, such as leather or the like, so as to deaden the clattering noise of contact between the plates.
As may be seen by Figs. 3 to 6 the s ring tongues e, f, are extended in opposite irections and are curved so as to mterlock and prevent their slipping off each other, when engaged as in Fig. 7, and said tongues when interlocked secure the removable lift a to the heel I). These interlocking spring tongues e, f, as compared with the securing devices elasticity, which is a feature of great practical importance if the removable lift does not fit the heel accurately.
Each holding plate 0, d, with its spring tongues, is preferably stamped in one piece and provided with ears g, h, by which the plates are readily fastened to the leather without nails or rivets. The metallic ears g, h, at the part of the heel subject to the greatest wear are preferably of trapezoid shape, and will impart greater strength to the removable lift, and more securely hold the leather, as the latter will expand tightly into the spaces between the ears.
To revent the outer lift being knocked ofi, a sma l screw .9 can be introduced into correspgnding holes "5, if, provided in the plates 0,
Instead of leather, rubber, wood or any other suitable material may be used to either entirely or artly form the heel and lift.
Having t us described my invention what I claim and desire to secure by Letters Patent of the United States is:
In combination with a boot or shoe heel, and a detachable lift therefor, of a metallic locking plate embedded in the bottom of the heel and provided with three rearwardly projecting curved tongues arranged two in front and one behind, and an opposed metallic plate embedded in the upper part of the lift and provided with three forwardly projecting curved tongues arranged two in front and one behind; said tongues being adapted to interlock and detachably fasten the lift to the heel, substantially as de scribed.
In testimony whereof I have hereunto set my hand in the presence of two witnesses.
