Application filed April 8, 1919. Serial No. 287,184.

To all whom it may concern: I

Be it known that I, Joan E. CRAonIcK, citizen of the United States, residin at Denver, in the county of Denver and btate of Colorado, have invented certain new and useful Improvements in Electrothermal Garments; and I do declare the following to be full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to electro-thermal garments and it relates more specifically to an improved thermo-magnetic health garment.

One object of this invention is to generally improve upon devices of'this character by applying my improved wiring system to my improved form of tubular body garment in a manner to obtain the most beneficial results. a

' Other objects and advantages ma become apparent to persons who read the f ollowing details of description in connection with the accompanying drawings in which:

Figure l is a front elevation of-my improved health garment, a portion being broken away to more clearly show the elec tric connection of the garment with a thermo-magnetic boot which may be connected with the arment.

Fig. 2 1s a front elevation ofthe inner fabric of'the garment and the electric conductor secured thereon.

Fig; 3 is a horizontal sectional view, the

section being taken along the line 3-3 of Fig. 1. ig. 4 is a perspective View of the inner fabric of one of my thermo-magnetic boots having an electric conductor wound around the same.

Fig. 5 is a horizontal section along the line 55 of Fig. 1.

Fig. 6 is a detail view illustrating a ver tical section through a portion of one of the boots shown in Figs. 1 and 4:.

Fig. 7 is a diagrammatic view illustrating the electric system or circuit employed in connection with the garment and boots disclosed in Figs. 1 to 6 inclusive.

Fig. 8 is a view somewhat similar to Fig. 1, of a modified form of the garment.

Fig. 9 is a diagrammatic view illustrating the electric system or circuit employed in connection with the garment and bootsdisclosed in Figs. 1 to 6 inclusive.

Referring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views, the tubular body garment comprises an outer fabric 10, an inner fabric 11 and an intermediate fabric 12, the latter having a conducting wire 13 extending spirally therearound and secured thereto by stitching or other appropriate means. The I outer fabric maybe of flannel or other soft and heat retaining material and it may be of the construction shown in Fig. 1, having sleeves 14, or it may be sleeveless as shown in Fig. 8. In each instance, however, the garment is tubular or continuous in the horizontal direction, that is, it is not designed to open either at the front or rear or at either side, but is open only at its top and bottom. As shown in both Figs. 1 and 8, and also in Fig. 3, the outer fabric is formed with a conduit 15, this conduit being formed of the meeting front edge portions of the fabric which forms the portion which surrounds the body. In formin this conduit, a row of stitching 16 extends rom the bottom to the top of the garment, and a, row of stitching 17 also extends from the bottom to the top and is substantially parallel with the stitching 16 and spaced therefrom a suiiicient distance to permit the substantially cylindrical conduit to be formed as more nearly disclosed in'Figs; 3-and 8.

Referring again to Fig. 3, in which the inner and outer fabrics or linings are more clearly shown, the intermediate fabric ma also be considered as an inner fabric, wit 1 reference to the outer fabric which incloses it. This inner or intermediate fabric 12 is preferably buckram or other relatively stiff material, so that the conducting wires which are attached thereto are held in the desired spaced relation to one another, and the Wires are more easily stitched to this material than to a material which has a less degree of stiffness.

The inner fabric 11 may be of any appropriate soft and yieldable material, and in inner fabric 11 ma be included or-"considered as a part of t e intermediate or inner fabric 12.

The boots 18 illustrated in Figs. 1,4, 5

plied on the fabric 19' a illustrated in Fig.

l 4. The terminals of the wires 20 connect ficiently strong current for the purpose of or turns 24 and 25 which serve as induction coils, the body of the per-.-

ductor 13, being of high resistance,

heating the conducting wires 13 and 20 to the desired temperature, but preferably, an

alternating current of high frequency is employed. A switch 23 may be conveniently located in the external source of current, so that the user of .thecurrent can turn the current on and off at will.

Still considering Figs. 2 and 7, it will be seen that the'circuit 13 comprises a plurality. of helical coils or turns 24 above the shoulder portions of the garment, a plurality of turns or coils 25 below the shoulders, and two series of turns 26, one series on each arm of the garment. In order to more clearly describethe circuit, the inner fabric may be considered as comprising a super-shoulder portion around which the turns 24' extend, a sub-shoulder portion around which the turns 25 extend, andtwo arm portions on which the turns 26-are secured. However, the turns 26 do not surrounud the arm portions, but this portion of the conductor ex: tends back and forth alon the arm ortion as illustrated inFig. 2. ITLBIGfOI'B, t e coils surround the body an ordithe 'connot only but son serving somewhat as a core 1n nary lnduction coil, and therefore,

transmit their heat to the wearers body,

the magnetic action ofthese wires beneficially affects the persons body in'ways that will readily be understood by physicians and others who are familiar with electric treatments of human bodies. However, the series of turns 26 on the arm portions, which do not surround the arm portions, merely 'transmit their heat to the arm portions.

From the foregoing description, it will be seen that the series of turns 24, the series of turns 26 and the series of turns 25 are connected in electrical series, and it will now be pointed out that the two series 26 are directly connected to one another.- This feature is clearl illustrated in the diagrammatic view, ig. 7, in which the horizontal section 27 is the direct means of connecting the two arm series 26. Therefore, considering that the current is flowing in the direction of the arrow in Fig. 7, it first passes through the super-shoulder series 24, then through the two arm'series 26, and then "portions 7 1 11 into the conduit 15 and thence down ment of parts,

through the sub-shoulder series 25. The sub-shoulder series of coils or turns 25 is tapped at 28, and the leads from the tapped 28 extend from the inner fabric through the-conduit and terminate in an at,- taching-plug-socket29 to which the attaching plug 21 ma when it is not esired to attach the plug 21, a circuit-closing plug 30 ma be employed as illustrated in Fig. 9. herefore,

f it will be seen that my improved body garused either in connection with I ment may be the boots 18 or without them. Obviously, the boots can also beeused separate from the body-garment, by attaching the plug 21 to a socket like the one designated 29, but connected to a conductor other than that of the body-garment. It will be seen that the boots can be used to magnetically treat the atients arms as well as the legs, and are a so useful toapply heat to parts of the trunk and neck of the person.

The upper turn of the super-shoulder section extends down through the conduit 15 to the middle front part of the garment, (that is, of the sub-shoulder section), and the lower turn of'the' sub-shoulder series extends upward through the conduit 15 (as illustrated in Fig. 2,) and these leads terminate in the socket of the plug-and-socket-connec-' illustrated in Fig. 9, it will be seen that it .be attached. However,

discloses substantiall thesame wiring sy.:-.,

tern as that disclose in Fig. 7 except that the arm series of turns may be eliminated.

When the modified form shown in Fi 8' is employed, hand holes 34 may be provi ed,

so that the pulse of the patient may be examined through these hand holes, and flaps 35 may be provided with snap fasteners or other securing means whereby the flaps may be secured in closed position.

Although I have described this embodiment of my invention very specifically, it is not intended to limit this invention to these exact details of construction and arrangebut I am entitled to make appropriate changes within the scope of the inventive idea. disclosed in the foregoing description and; following claims.

What I claim as my invention is:

.1.' In a device of the character described,

a body garment having, inner-and outer fab: rics,'said outer fabric having edge portions that are secured along two lines u the front part of the garment to orm a con-.

duit, and an electric circuit comprising a series of turns of. conducting wire secured and down between said inner and outer fabrics, said series extending from the u per part ofthe garment to the lower part t ereof and haviso ing upper and lower terminals meeting with- I i in 211 conduit and extending outward laterally of the conduit and terminating in an attaching plug 2. In a device for" electrically treating a person, a body garment having sleeves and eing open at to and bottom but having all its upright si es closed, said garment including a tubular flexible inner lining, a

series of helical turns of conducting wire of conducting wire above and below and on.

said sleeves being electrically connected in series.

3. In a garment for electrically treating persons, a body garment 0 en at both ends and closed at front and bac said body garment including a tubular flexible inner lining, a series of helical turns of conducting wire secured on and extending spirally around said tubular inner lining in such relation that they combine to form a solenoid for inducing magnetism in the bodies of persons Who Wear the garment, a tubular member to receive a limb of a person being treated, a series of helical coils forming a solenoid around this limb-receiving member, means to detachably connect the solenoid of the body garment in series with, that of said limb-receiving member, and means to close the circuit of the first said solenoid when the limb-receiving member is detached,

for; the purpose specified.

In testimony whereof I have hereunto set in hand.
