APPARATUS FOR TREATMENT THE FEET.
Application filed November 3, 1921. Serial No. 512,452.
To all whom it may concern:
Be it known that I, MARY A. RADFORD a citizen of United States, and a resident of Oakland, county of Alameda, State of California, have invented a new and useful Apparatus for Treatment of the Feet, of Which the following is a specification. My invention relates to an apparatus for treating foot ailments, such as corns, calluses, bunions, etc.
I An object of the invention is to provide means of. the character described by .the,use
of which both light. and severe cases of various foot ailments may be relieved or entirely overcome in a minimum space of time. Y
Another object of'th'e invention is to pro- 'vide an apparatus of the character described which is extremely simple in construction, readil kept sanitary, and applicable for use with either foot. y I The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following .description of the preferredform of my lnvention which is" illustrated in the 41s glands, and trap ing the resultant mois-.
drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawingsand description,
as I may adopt variations of the preferred form within the scope of my. lnventlon as set forth in the claim.
Referring to said drawings:
Figure 1 is a perspectiveview of the outer member of the apparatus;
Figure 2 is a longitudinal section of the inner and outer members of the assembled device.
mem r. v
Very briefly expressed the method I use for treating the foot, substantially comprises in heating the foot to a degree producing excessive dilation of the sweat ture dischar 'ng rom the foot during such dilation. T e apparatus for efiecting the above, as here shown includes a rather tightly fittin rubber stocking in which the foot is place a loosely fitting shoe in which the stocking-covered foot is inserted, and an electric heating element arranged in the soleof the shoe.
.A detailed description follows: p
The apparatus in its present form, comre 3 is a bottom view of the outer upon the barefoot that is to be treated.
The stocking is of a size to fit the foot *rather snugly and preferably extends above the ankle.
comprises a shoe 6 preferably made of rubber, canvas, or similar material, and provlded with inner and outer 'soles 7 and 8 respectively, which are formed of a dielectrical material such as rubber. The shoe is made large enough to readily enable it to fit either foot of the person. In this mannerwhen the foot is held in the stocking and has been inserted in the shoe, a comparatively large space will be had between the major portion of the side walls of the stocking and shoe, the advantage of which will be presently explained. Arranged between the soles 7 and 8 is an electric heating element 9 which is provided with the leads 10 that extend from the rear of the shoe and are adapted to be connected to'any suitable source of electric supply.
In the use of the apparatus the foot is slipped into the 'rubber stocking and is then inserted therewith in the shoe, after which .the latter is laced and tied in the usual manner. The heating element is then ener ized and the device thus commences to function As soon as the interior of shoe becomes heated andthe heat thence transmitted' from the stocking to the foot, there is produced. in the latter an excessive dilationor functioning of the" sweat glands. The rubber stocking being non-porous, the moisture exuded through the pores of the foot is prevented from escaping, thus causing the abnormal skin to be subjected'to a sweltering action. The operation of the device is continued until such time as the operation. As hereinbefore mentioned a.
space is provided betweenthe side walls of manner the warm air currents may effec- The outer member 3 of the apparatus as stocking and tliose of the shoe. In this foot and said" stocking are adapted be encased, and a heating element associated with said shoe.
In Witness whereof, I have hereunto set my hand at Oakland, California, this 25th 4 day of October, 1921.
