CHARLES E. KENNEDY AND GUY M. CUSHING, OF CHICAGO, ILLINOIS.
HEATING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 714,192, dated November 25, 1902. Application led December 26, 1901. Serial No. 87,350. (No model.)
To a/ZZ whom', it may concern.-
Beit known that We, CHARLES E. KENNEDY and GUY M. CUSHING, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain newA and useful Improvements in Heating Apparatus, of which the following is a specification.
This invention relates to improvements in a heating apparatus, and while it is more especially intended to be used as a foot-warmer for carriages, buggies, cabs, and the like, yet it may be employed as a heater for any desired or suitable purpose; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.
Heretofore in footwarmers or heaters of an analogous class alcohol or small oil lamps have generally been employed for generating heat, and it is Well known that these lamps must be supplied with air or they will become extinguished.
In constructing the foot warmers or heaters so as to supply the necessary quantity of air or oxygen to the lamp to cause combustion the air ports or openings must necessarily be exposed, thus allowing the cold air to reach the feet of the user and also to circulate through the warmer, thus cooling it to a great extent and preventing it becoming heated to a high degree.. In other Words, the foot warmers or heaters of the class now under consideration could not be entirely Wrapped up and still continue to produce heat. It is therefore among the principal objects of our invention to provide an apparatus which may be entirely covered by means of a lap-robe or other covering without interfering with the continued generation of heat and which shall be simple and inexpensive in construction, strong, durable, and effective in operation.
In order to enable others skilled in the art to which our invention pertains to make and use the same, We will now proceed to describe it, referring to the accompanying drawings, in which- Figure lis a perspective View of a heater or foot-Warmer embodying our novel construction. Fig. 2 is a central longitudinal sectional view thereof. Fig. 3 is a central transverse sectional view; and Fig. 4 is a view, partly in section and partly in elevation, of the removable head of the heater.
Similar letters refer to like parts throughout the different views of the drawings.
A represents the body of our heater, which may be made of any suitable size, form, and material, but preferably of sheet metal, and of substantially the shape shown in the drawings-that is to say, substantially elliptical in cross-section.
One end of the vessel or body A is closed and is provided on its inner surface with a block of Wood or other suitable material et to brace or reinforce the same. This end of the body, as well as the removable head B, is provided With a handle b to be used for lifting or moving the apparatus. The opposite end of the bodyA from that in which the piece o. is located is open to receive the removable head B, which is preferably made of wood of a suitable size and form to fit snugly within said end. The edge of the head B is slightly tapered, as at b', (see Fig. 4,) to cause it to be easily inserted, yet to t closely the end of the body.
Secured to the outer surface of the head B and surrounding its edge is a plate c, which is located far enough away from the edge of the head to permit the rim of the body A to be inserted therebetween. The upper central portion of the body is provided with a down wardly-extending depression d, through the center of which extends a tube D, which has just above the upper surface of the depression d an opening d', as is clearly shown in Figs. 2 and 3 of the drawings.
Located on the upper surface of the body A is a Water-reservoir E, which is provided at its middle with an opening e, communicating with its interior just above the depression d in the top of the body. Surrounding the opening e and extending upwardly is a screw-threaded tubular neck c', on which is tted. a screw-threaded cap e2 to close the same. As shown, the tube D extends upwardly through the opening e and into the neck e and near its top.
In using our heating apparatus we place a quantity of u'nslaked lime in the body or vessel A-about enough to ll it half full. The reservoir E is then filled or partially lled IOO with water and the cap e2 screwed down in place. The lime is then subjected to a quantity of water which will cause it to slake, and thus liberate the latent heat therein contained, which will rise from the lime in the form of steam or vapor, which will strike the curved surface of the body or vessel A and be carried down at its sides to again act on the lime. While this is taking place the water from the reservoir will llow through the opening d in the tube D into the vessel A in a gradualmanner, thus feeding a sufficient quantity of water to cause the lime to continue to slake and produce heat and steam. As the steam rises from the lime a portion of it will pass through the tube D and from its upper end into the neck e' and from thence into the reservoir E, thus creating a suicient pressure on the water in the reservoir to cause it to liow through the opening d in the tube. While the foregoing action is taking place it is apparent that the water Within the reservoir Will become heated and will retain the heat for a great length of time.
Havingv thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, isu 1. In a heating apparatus, the combination with a body or vessel having in its upper portion a downward and transverse depression, ot' a reservoir on the upper portion of the body and having means to open and close the same, a tube having an opening in its lower portion and communicating with the body and reservoir through the depression in the former, and means to open and close the body,
substantially as described.
2. In a heating apparatus, the combination with a body or vessel having a removable head at one of its ends and a depression in its central upper portion, of a reservoir located on the upper portion of the body and having an upwardly-extending neck at its middle, a tube having an opening near its lower end and extending through the depressed part of the body and into the neck of the reservoir, and a cap detachably located on the said neck but at a distance from the upper end of the tube therein, substantially as described.
