T. H. M COMSEY ELECTRIC PAD Filed April 6. 1926 entree stares PATENT THOMAS 3:1. IVECCCOT'IZSEY, OIL LOS ANGELES, CALIFORNIA.
ELECTRIC PAD.
Application filed April 6,
This invention relates to improvements in electrically heated pads and more particularly to pads for therapeutical treatment of the human body.
Among the objects of my invention is to provide an anatomically shaped pad and heat unit whereby the pad, as a whole will closely conform to the body and the heat therefrom be uniformly distributed and applied over the body.
Another object is to provide a heat unit comprising a plurality of coils of substantially oblong shapes and having rounded ends and a single coil of substantially U- shape, all formed from a continuous length of wire and relatively fabricated as by ribbons or tapes to comprise a flexible and anatomy conforming heat unit for treatmentof the human body particularly about the neck and upper body.
My improvements consist in the novel. construction, arrangement and combination of parts as hereinafter fully, clearly and concisely described, definitely pointed out in my claims and illustrated by the accompanying drawing (1 sheet) in which Fig. 1 is a view in perspective of a device constructed in accordance with my invention;
Fig. 2 is an elevation with one of the pad sections removed and shows the relative disposition of the several coils of the heat unit and control therefor;
Fig. 3 is a wiring diagram;
Fig. 4 is an enlarged transverse section elevation, taken on the line 4--lof Fig. 2 showing the fabrication of the several coils.
Referring more specifically to the drawing, the numerals and 11 designate the front and back sections of the pad, or heat unit envelope, which in its finished state, has a seam uniting the two sections at their margins for the complete enveloping and retention of the heat unit and by preference such pad sections are made of woolen cloth.
The heat unit comprises one or more coils 12 of oblong contour having substantially straight, parallel sides and rounded ends and built up of a continuous length of wire, such as insulated magnet wire of approximately 21 gage and of single strand.
This shaping of the coil affords maximum flexibility and adapts the coil as a whole to conform readily to the anatomical part to be treated and, such shaping of the coil obviates 1926. Serial No. 100,036.
sharp angles in the wires which tend to breakage.
Associated with the coil or coils, just recited, is a similarly built up coil 13, whose major lengths are arcuate for close fitment about the neck and shoulders of the users.
In the single length of wire entering into and forming the coils 12 and 13, I provide interconnecting, loose lengths 14, providing fiexure between the various coils and I further provide structure bonds between the various coils in the form of flexible ribbons, or tapes extending between and uniting the lengths of the coils by tying or knotting between the coils as best shown in Figs. 2 and 4:. The ends of the wire are connected in a connector with a source of electrical supply, such as the plug 16, shown in Figs. 1 and 3.
For the control of energy flow through the various coils I provide a control 17, which by preference is a thermostatic switch (of any approved construction) which maintains uniformity of action and prevents overheating.
By further preference, and as shown in Figs. 2 and 3, I provide two of such control devices, whereby the pad may be used with high or low voltage circuits and by further preference such controls are incorporated within the pad body or envelope as shown.
I claim 1. In a. device of the class described, a heating unit comprising a plurality of coils constructed of a single length of wire and each having spaced parallel sides and rounded ends, said wire extending loosely between the coils, a fabric envelope enclosing said coils and a flexible structure bond independent of said fabric envelope between the coils.
2. A device of the class described comprising a plurality of coils having straight parallel sides and rounded ends, a single coil having arcuate sides and rounded ends, flexible electrical connections between the various coils, a flexible structure bond between the lengths of the various coils, a. textile envelope enclosing said bond and coils, and a. thermostatic control for the energy flow through the coils.
3. A device of the class described comprising a body portion, containing a plurality of transversely extending coils having strai ht parallel sides and rounded ends; in corn ination Wit-h e neck portion having a coil with an 'arouate side portion and rounded ends, flexible electric connections between the Various coils, a i 'abrie envelope enclosing all mid-length of said areuate coil and confabric envelope.
nected to" the adjacent straight coil, and
tape bondseonnecting together the straight 10- leads of the other coils, said tape bonds be-j ing independent of the structure of said In testimony whereof, I have afiixed my signature.
