Description

Dec. 31, 1935. A. KURTZ FOOT WARMING DEVICE Filed July 5, 1934 INVENTOR flizarew fi'mriz' F M fl ATTORNEY Patented Dec. 31, 1935 UNITED STATES- PATENT OFFICE 1 Claim.
This invention relates to shoe warming devices in which the shoe is provided with means to impart warmth to-the feet of a person wearing same.
One of the objects-of the invention is to provide a device, directly incorporated in the structure, whereby an electric circuit is caused to be generated causing a desirable degree of warmth in the sole of a shoe, rendering the wearer comfortable even in extreme cold.
A further feature is the provision of a heating device which nowise obstructs or interferes with the free and unimpeded movements of the wearer of the shoe and which is substantially invisible to an observer.
A further aim is to provide a foot warmer which can be applied to any ordinary shoe as a permanent part thereof, at a moderate cost.
Another object is the provision of a foot warmer of this character, which may be replaced if worn out, and which will permit the re-soling andrepairing of a shoe of which it is a part.
These and other objects and advantages are attained by the novel construction, combination and arrangement of parts hereinafter described and illustrated in the accompanying drawing, forming a material part of this disclosure, and in which:
Figure l is a perspective view of a conventional shoe, showing application of the device.
Figure 2 is a partial side elevational, partial sectional view of thesame.
Figure 3 is a rear elevational view thereof.
Figure 4 is a perspective view of an intermediate sole, carrying the heating element.
Figure 5 is a transverse sectional view taken on line 5-5 of Figure 4 and drawn to an enlarged sca e.
The shoe shown consists, as usual, of a. vamp l0, having a toe II and uppers i2 provided with lacing holes l8.
At the rear or heel portion of the upper is a lining l4 below which is a stiffener or counter II, the lower edge of the upper and counter being inturned below an inner sole I! under which is a thin, water-proof liner i'l, while the outer or bottom sole is arranged in its usual manner and has attached the lift or heel ll.
Between the liner i1 and the outer solev I9- is inserted a flexible plate of dielectric material having a profile corresponding to the sole l8, and secured on its under surface is a relatively thin, non-conducting sheet II.
A high resistant wire 22 is bent to present a loop disposed between the plate it and sheet 2i, adjacent the margin, as best seen in Figures 4 and 5, the ends of the wire being set in insulators 23, 24, upturned at the heel and held in 5 contact with the upper M by a patch 25 acting as a guard to avoid injury to the insulators.
A bracket 28 of flexible material, as leather, is
stitched between the upper l2 and inner it at their upper sides, its outstanding portion being 10 reinforced by non-conducting plates 2'l-28 in which are adjustably secured a pair of socket posts 29-30 adapted to receive the respective terminals 8|-32 of a conducting cable 33, leading to a plug 34 provided with a switch 35.
Theplug all may be engaged with any convenient source of electrical supply, as for instance a six volt battery carried on the person wearing the shoe. or on some part of structure occupied by him, as for instance an automobile, boat, airplane etc., the cable 38 passing below the wearer's clothing to engage the posts.
Due to the disposition of the resistance 22, the entire lower portion of the shoe will be uniformly heated during the time the current is turned on.
By reason of its construction, the shoe may be re-soied or repaired without injury to the heating elements, and the heating elements may be replaced, if no longer fit for use.
Although the foregoing is descriptive of th preferred embodiment of the invention, it will be apparent that changes may be made in the construction without departure from the spirit of the invention, as set forth in the appended claim.
Having thus described the invention, whatis claimed as new and desired to be secured by Letters Patent, is:
In a shoe warmer, the combination with a shoe 40 having inner and outer soles, of a resistance wire having a loop spaced from the edges of said soles and disposed therebetween, an insulating plate below said loop, insulated cables engaging the ends of said wires and extending upwardly exteriorly of the heel portion of theshoe, a flexible bracket fixed at the upper edge of the shoe to extend rearwardly therefrom, socket posts fixed in said bracket in engagement with the opposite ends of said cable, a cover over said cables, and means to connect said posts with a source of electricity.
