JACOB M. CRIPE, OF MATTOON, ILLINOIS.

PORTABLE RADIATOR.

SPECIFICATION forming part of Letters Patent N 0. 722,286, dated March 10, 1903.

Application filed March 13 1902. Serial No. 98,083. (No model.) 7

To all whom it may concern:

Be it known that I, JACOB M. CRIPE, a citizen of the United States, residing at Mattoon, in the county of Ooles and State of Illinois, have invented a new and useful Portable Radiator, of which the following is a specification.

This invention relates to radiators,and particularly to that class adapted to be moved from point to point as desired as distinguished from radiators of that class that are rigidly associated with their steam or hot-water supply pipes.

The object of the invention is to provide a novel form of combined steam and hot-water radiator in which heating of the water will be effected with the expenditure of the minimum of fuel,and,further,one in which oil may be employed as a heating medium.

A further object is to obviate danger of explosion, as from overheating, by the provision of a suitable expansion chamber provided with steam-escape means by which excessive pressure on the radiator may be automatically and positively relieved.

lVith these and other objects in View, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a radiator, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a View in elevation, partly in section, of a radiator embodying the essential features of the invention. Fig. 2 is a view in transverse section, taken on the line 2 2, Fig. 1, and looking in the direction of the arrow thereon.

Referring to the drawings, 1 designates a radiator, which may be of the usual or any preferred construction. Associated with one end of the radiator is the heating means, comprising a casing 2, housing a heating-chamber 3, the same comprising, preferably, ahollow circular structure of a diameter practically to fill the casing from side to side, there being a slight'space 4 left between the periphery of the heating-chamber for the escape of the unconsumed products of combustion above the heating-chamber and out through a flue 5, Which may connectwith a chimney or Stovepipe. The heating medium in the present instance is designed to be oil, and this is contained in a suitable holder 5, provided with a wick or burner 5, air being supplied to the casing to support combustion through orifices 6 in the bottom of the casing, only one of the orifices being shown in this instance. By having the heating-chamber arranged as described a very large area is presented for direct impingement by the flame of the burning oil, so that the Water contained within the heatingchamber and radiator will be rapidly heated and held at the desired temperature. Any preferred form of lamp or burner may be employed for the purpose, and this being Well understood, an oil-burner is herein indicated diagrammaticallv.

Tapped into the under plate of the heatingchamber 3 is one end of a pipe 7, which extends down through the casing 2 and connects at its other end with the end tube or coil A of the radiator, the coils of which are disposed vertically, thereby to efiect more rapid circulation of the Water contained therein. Tapped into the upper plate of the heating-chamber, preferably at its center, is one end of a pipe 8, which extends upward through the casing and is connected at its other end with the upper portion of the tube or coil A. Connecting with the other end tube or coil B is one end of a pipe 9, the other end of which is tapped into a vertically-disposed member of an expansion'chamber 10, the same being an approximately L-shaped structure having its shorter leg 10 disposed parallel with the end tube B and extended downward approximately one-half its length and its longer leg 1O disposed upon the top of the radiator. The upper portion of the tube B has connected with it one end of a pipe 11, the other end of which projects through the shorter leg of the expansion-chamber and upward therein to a point near the top of the longer leg, as

clearly shown in Fig. 1. The expansionchamber is provided with a filling-opening 12, normally covered by a screw-cap 13, with a safety-valve 14 of any preferred character, and with an air-escape cock 15.

As before stated, this radiator is adapted to be used either as a hot-water or a steam radiator. Where used for hot-water heating, the entire system is filled with water until the tank is about two-thirds full, as indicated by the dotted line x w. The burner being started, the water in the heating-chamber is rapidly heated and starts up a circulation through the system, and so long as the temperature therein remains normal the water will circulate from the heating-chamber through the pipe 8 to the radiator and across to the opposite end thereof, thence downward and through the pipe 7 back to the heating-chamber; but should the temperature become excessive the water passing through the pipe 8 will traverse the upper portion of the radiator and thence escape to the expansion-chamber, where the excess of pressure is relieved by the safety-valve, and the water in the tank will then pass through the pipe 9 back to the radiator and thence through the pipe 7 to the heating-chamber. Should an accumulation of air in the coils of the radiator or in the expansion-chamber operate to prevent the system from performing its functions properly, this may be obviated by opening the air-cock 15. Where the system is to be used for steamheating, the radiator will be supplied with water to a point just above the heating-chamher, as indicated by the dotted line y g.

It will be seen from the foregoing description that although the device of this invention is exceedingly simple of construction it will be found thoroughly efficient and practical in use, and by reason of the fact that all of the parts adjunctive to the radiator are rigidly associated therewith that the device may be transported from point to point as desired.

While oil is herein mentioned as the heating medium, it is to be understood that gas, either natural or artificial, or gasolene may be employed as a fuel and still be within the scope of the invention.

An advantage accruing from the disposition of the heating-chamber in the casing 2 in the manner described is that the products of combustion are retarded in their escape, so that practically all of the heat units are utilized for doing effective work before escape.

It is a recognized desideratum that moisture should be supplied to the atmosphere of the room containing a heater to compensate for that eliminated, and this is effectively accomplished in the present device by the moisture contained in the steam that escapes from the safety-Valve. In other words, aside from its high heating qualities a radiator constructed as described will present sanitary advantages not obtainable in the ordinary forms of hot-water or steam radiators.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a radiator of a water-heating chamber, pipes connecting the chamber with the upper and lower portions of one end tube of the radiator, an expansionchamberhavingahorizontal member disposed above the radiator and a vertical member, constituting a drop-leg, disposed adjacent to the other end tube, a pipe connecting the lower end of the drop-leg with the lower portion of the last-named end tube, and a pipe connected with the upper portion of the latter end tube and projecting into the drop-leg and upward into the horizontal member.

2. The combination with a radiator, of a water-heating chamber, pipes connecting the chamber with the upper and lower portions of one end tube of the radiator, an expansionchamber having one member disposed on the top of the radiator and another member, constituting a drop-leg, disposed parallel with the other end tube,a pipe connecting the lower end of the drop-leg with the lower portion of the last-named tube, and a pipe connected with the upper portion of the latter end tube and projecting into the drop-leg and upward into the horizontal member.

3. The combination with a radiator, of a water-heater supported thereby and comprising a hollow circular disk having its upper and lower walls closely juxtaposed, a casing inclosing the disk and provided with means for burning liquid fuel, pipes connecting the upper and lower walls of the heating-chamber with the upper and lower portion of one end tube of the radiator, an expansion-chamher, a pipe connecting the other end tube of the radiator with the lower portion of the expansion-chamber, and a pipe connected with the upper portion of the last-named end tube and projecting upward into the expansionchamber.

4. The combination with a radiator, of a water-heating chamber, pipes connecting the chamber with the upper and lower portions of one end tube of the radiator, an expansionchamber comprising two members, one of which is substantially coextensive with the length of the radiator and is provided with filling means, a safety-valve and an air-cook, and the other member which constitutes a drop-leg being disposed parallel with the other end tube, a pipe connecting the lower end of the drop-leg with the lower portion of the last-named tube, and a pipe connected with the upper portion of the latter end tube and projecting into the drop-leg and upward therein to a point near the top of the horizontal member.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
