CLARA A. B. KINCAID, OF INDIANAPOLIS, INDIANA.
CHEMICAL HEATEREI Specification of Iletters Patent. 1
Patented Feb. 20, 1917.
Application filed July 28, 1916. SeriaI'No. 111,842.
To all whom it may concern:
Be it known that I, CLARA A. B. KINCAID, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Chemical Heaters, of which the following is a specification.
This invention relates to a device for producing artificial heat by chemical action, for
local application to the human body in the treatment of disease, for use in bed to warm the feet or other parts of the human body, for use in road vehicles, boats, airships and the like, not provided with other means for general heating, for warming food, for ironing clothes and for the many and various purposes to which it is applicable within its range of heat development.
The object of the invention is to provide a device which will be inexpensive to manufacture and maintain, which is readily portable and can be conveniently applied to various uses, which is simple to operate without danger of injurious results and the activity of which is of long enough duration after each charge to be of great practicability.
I accomplish the above, and other objects which will hereinafter appear, by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a top plan view and partial horizontal section of one form of my invention and Fig. 2 is an elevation and partial vertical section of the same.
Like characters of reference indicate like parts throughout the two views.
The form here shown is only by way of illustration, as it will be self evident to those skilled in the art, after a comprehension of the means here shown, that the device may be made in many different shapes, such as square, rectangular, oval, pentagonal and the like, without departing from the spirit of my invention, nor do I desire to be limited in dimensions, it being equally obvious that the size will depend upon the amount of surface to be heated and the quantity of artificial heat desired to be produced by it. Referring to the drawings, 3 is a cylindrical box formed out of copper, having but a single opening which is through its top and is surrounded by a tube 4: which is externally screw-threaded to receive an internally screw-threaded cap 5, which screws on said tube and closes the box in an air-tight manner at certain positions. The cap is provided with an opening 6, through its side which is closed by screwing the cap sufficiently far down on the tube, and, is opened to charge the box with air by screwing the cap outwardly on the tube.
Within the box 3 is a cup 7, the bottom of which rests upon the bottom of the box, and the walls of which are close to the sides of the box. This cup is preferably formed of zinc which I have found to give most favor able results.
Within the cup 7 is a ring 8 of copper which is preferably secured by soldering or otherwise to the bottom of the cup. p
A chemical action on and between the above metals is produced by means of a suitable chemical introduced into the interior of the resulting above-described receptacle by removing the cap 5. This chemical is active when supplied with air which is done by unscrewing the cap until an air passage between the interior of the receptacle and atmosphere is established'through the opening 6. I Heat is generated through the above action and is radiated from top, bottom and sides of the box 3, and the generation of heat continues for several hours after the opening to atmosphere is closed. Various While I have described my invention.
with more or less minuteness as regards details of construction and arrangement and as being embodied in certain precise forms, I do not desire to be limited thereto unduly -or any more than is pointed out in the claims. On the contrary, I contemplate all proper changes in form, material, construction and arrangement, the omission of immaterial elements and the substitution of equivalents as circumstances may suggest or as necessity may render expedient.
I -claim 1. In a'chemical heater, a copperbox having a single opening, means for regulating the supply of air through said opening into the box, a zinc lining in said box, and an 1 agent in the box acting with said metals for creating chemical activity.
2. In a chemical heater, a copper box having a single opening, an externally threaded tube into which said opening discharges a '.cap screwing on saidtube having a hole 1n its wall opened and closed to atmosphere by screwing the cap out or in, a zinc cup 111 said box, a copper member in said cup and a chemical agent in the receptacle thus formed 10 my hand and seal at Indianapolis, Indiana, 15
