HEATING ran.
' This invention relates to heating pads, particularly such heating pads as are used or heatin beds of the sick or" those deficient in natural heat, or for general use. The invention presents an arrangement .of parts which overcomes many disadvantagespf other heating pads and adds greatly 1 to the efliciency of the heating combination as well as increasing the comfort of the user.
It is my purpose in this invention to provide direct heat to the body, there being no covering or coating directly on the heating element itself,'the heating element sending its heat rays directly to the body supplying 1:, thereby a more energizing heat.
Means are also provided to direct the heat upward and to prevent downward radiation,
and thereby use to the eatest extent, the heat energy produced.
cans are also pro- '20 vided to supply this heat in a-particular 'zone of the'bed as may be found most desirable as well as necessary and eflicientl Means are also provided whereby the vari- 'ouszones of heat may be made efiective, either singly or together, the'zone of heat being under control of the user in such a manner that either of the several zones may i be made effective,
tive, and any single zone or all may be discontinued or cut ofi, as found necessary.
. In the drawing; Fisgli 1, is a perspective view of the warming pad owing three heatin zones,
in arrangement,
Fig. 2, isa diagrammatic view of the wirh and Fig. 4,-is a perspective view of a portidn of one' of the heating tubes the heating ele- 4o ment therein. The pad 1 is: made up of a base 2 upon which are mounted, in any suitable manner, the several sets of heating tubes'marked 3,4, and 5, and within which are the heating ele- 5 ments or wires 6, hand 8.
v The pad may be dividedinto two parts,- the part 12 which extends from the end marked 9 to the dotted line 10 and is covered by the lpillow,'and the part 13 which extends e line 10 to the end marked 14,'uppn which the bodyrests. 4
The base2 may be of'any suitableheatinsulating material, such as asbestos cloth, u on this base 2, l6 and between thelin'e' 10 and t c 81 51 4, I provide the perforated heating tubes 6, 7, amil .8,
the end 14, and each consists of a or all may be made efiec- 1 ig. 3, 1s a section on line "-3- -3- of Fig. 1,
secured to the base 2 in any suitable manner,
. ing tubes 3, 4, and 5 are made of bakelite or kindred non-conducting material, being sufficiently rigid to revent collapsing under the weight of the body and at the same time flexible enough to yield somewhat to conform to the bod and inside these tubes I provide heating elements 6, 7, and 8 usually in the form of wire. I v 4 The central group of these tubes marked 3 extends from the line 10 to a point near the foot and consists of a plurality of perforated 7 tubes 3, Fig. 4, through which a, heating element 6 passes, being cont uous from the point 18 through the severa rows of tubes to the oint 19. W
T e two side groups 5, 5, extend from the 7 line 10- about two-thirds of the distance to lurality of perforated tubes through whic pass the heating elements 8, .8, being continuous through the several tubes from point 20 to point 21, and from point 22 to point 23, these side groups 5, 5, being adapted to-act together. v
On each side of the group 3 and between this group and the side groups 5, 5, I place intermediate groups 4, 4, extending from line i 10 to a point near the foot 14, these groups like roups 3 and 5 are made up of a series of tulies perforated on their upper side and tirely through the tubes being continuous through one section 4, from point-24 to point 25 and through the other section 4, from point 26 to point 27. Electric current from a suitable source is 95 supplied through a multiple switch 31 from t e wires 32 and 33, and a lead wire 30 from, the switch 31 connects the wire 32 to-the heating element 6at the point 18, a lead wire 35 connects the switch 34 of the multiple switch 1 0 31, to the heating elements 6 at the point 19., the switch 34 being adapted to form electrical connection between the lead wire 35 and the sup 1y wire 33 thereby closing-the circuit of the heating element 6 to make it operative. I 101i A lead wire'38 from the switch 37 is connected to one part of the heating element 8 at.
'23, the cross connecting wire 39: connecting element 8 at 21 to the lead wire 30, and thereaving heating elements 7, 7 ,which pass enby to the supply wire 32, the switch '37 being adapted to close the circuit through the heating elements 8, to thereby render them operative.
A lead wire 42 connects the switch 36 with one section of the heating element 7 at point 25, and a cross connecting wire 43 connected to this part of the heating element 7 at point 24, is connected to the other part of the heating element 7 at 27, the free end of the heating element 7 being connected at 26 to a lead wire 41, which in turn is connected to lead -wire 30, and thereby'to supply wire 32,
The switch 36 is adapted to, connect the lead wire 42 with the supply wire 33 thereby closing the electrical circuit through heating elements 7 and rendering them operative.
The lead wires 30, 35, 38, 42, 40 and 41,be-
' ing properly insulated are partially embedded in that'portion of the pad between the line 10 and the end 9, while the lead wires 40 and '41, together with the cross connecting wires 39 and 43, being properly insulated are entirely embedded in that portion of the pad,
between the line 10 and the end 9.
Between the tubes of the several sections, and on that portion of the pad which is not traversed by the tubes, I provide a filler of asbestos, wool, felt, or equivalent material which is secured to the base 2 in any suitable manner. A
In operation I place the pad on a bed, with the end 9 to the head and the end 14 to the foot thereof, the pillow occupying the space between line 10 and end 9, the sleeper resting upon the pad 1, and one or more of the switches 34, 36, 37 closed, whereby suflicient heat will be supplied through the tubes to- 'provide comfort and protect the sleeper against being chilled, making very light cover suflicient and thereby adding greatly to the rest of the sleeper.
. It will be understood that I have eirplained one system" of tubes, wiring and switches, and
' any other system may be used, as .there are .many wiring and switch systems known in the art. The groups .of tubing may be distributed on the padin any form and location, or one unit system may be used by me; and various areas thereof be heated as may be i needed for the specific purpose for which the 1. A heating pad comprising a base, a tube of insulating material resting on the base,
capable of flexing longitudinally, and having suflicient rigidity to prevent collapsing of the same, and an electric heating element arranged in the tube,'the tube being perforated along one side to permit the radiation of heat through the wall of the same, the remainder of the tube being imperforate.
2. A heating padcomprising a flexible sheet of insulating material forming a base, a substantially rigid tube of insulating material secured to the base and extending back and forth over the base to provide a tortuous chamber, said tube having unobstructed perforations on its upper side, and the remainder of the tube being imperforate, a layer of In- .sulating material arranged'on the base and of a thickness equal to the diameter 'of the tube, said filling material being arranged on opposite sides of the tube, and an electric heating element arranged, in said chamber.
