Serial No. 428,289.

To all whom it may concern:

Be it known that 1, WILLIAM AKIN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Gas Heater and Cooker, of which the following is a specification.

This invention relates to a device ada ted to be used for heating rooms or for coo ing purposes and one important object of the invention is to prevent the heat from rising upward from the burner, and to cause the heat to be radiated in all directions laterally from the burner so that the heat is diffused and radiated over a large area of the room, when the device is used as a heater.

Another object is to obviate dryness of the air by supplying moisture thereto and to prevent too rapid evaporation of the water which furnishes the moisture so that a given amount will last a long time without requiring-renewal.

Another object is to providefor regulating the position of the water supply and to thereby control the rate of evaporation.

Another object is to so construct the device that it may be applied to and supported by a gas fixture, or may be supported by its own frame in any position on a table or the floor and connected by a flexible hose with the gas supply.

The accompanying drawings illustrate the invention, and referring thereto :F igure 1 is a vertical cross section on line 9: a, Fig. 2. Fig. 2 is a longitudinal cross section-on line 0 -50 Fig. 1. Fig. 3 is a planview in detail, of the device for detachably securing the spreader. Fig. 4 is a vertical cross section through the device as applied to a gas fixture.

Referring to Figs. 1 and 2, the standard comprises three legs 1 which are united and braced at an intermediate point by a ring 2 and being secured at the top to a ring 3. bar 4 extends diametrically across the standard, being secured at one end to a leg 1 and the ring 2, and at its other end to the ring 2. A strap 5 is screwed to one side of the center part of bar 4 and the bar 4 and strap 5 are bowed out at 6, each for a half circle, so that a circular hole is formed in which is clamped a vertical pipe 7, the lower end of Which has a valve 8 which is connected by a hose 9 through which the gas is supplied. Screwed to the upper end of the pipe 7 is a burner 10 having orifices 11 from which the flame issues. The burner may be readily unscrewed from the pipe 7 whenever desired. The upper end of the burner comprises a cap 12 which is removable. The upper ends 13 of legs 1 are formed with hooks 14 which support the rim of a dished spreader 15 having a cupped central portion 16 which rests on top of the burner cap 12. Above the spreader 15 is an upper spreader 17 having a depressed cupped central portion 18 which nests in the cupped portion 16 of the lower spreader, and is formed with an annular bead 19 which rests on the flat top of the lower spreader and thus pervents the upper spreader from tipping. A screw 20 passes through the two spreaders into the burner cap 12 and under the head of the screw is an elongated button or washer 21 which clamps the spreaders securely in place.

The upper spreader has an elongated opening 22 a trifle larger than the washer 21 so that by turning the upper spreader and bringing the opening 22 into register with the washer 21 the spreader may be lifted off. This fastening device enables ready attachment or detachment of the spreaders. A cone 23 is removably seated on the upper spreader 17 and hides the fastening device, the latter being readily accessible upon lifting the cone. A disk 24 of asbestos is arranged below the cone 23 and effectively aids in preventing the heat from passing upwardly.' The rim of the lower spreader is supported by the hooks of the frame so that the spreader is held firmly in position against tipping and relieves the burner from its weight so that heavy dishes or flat irons may be heated on the lower s reader whenever desired. The upper sprea er 17 is supported sufficiently above the lower spreader to form an air space between them which is a most important feature in preventing the upward passage of heat. The flame issuing from the burner is spread laterally by the lower spreader and thrown out radially into the room thereby diffusing the heat uniformly throughout a large area. I have found in practice that best results are obtained by arranging the rims of both spreaders in the same horizontal plane.

A water pan 25 is adjustably supported on the ipe 7 by a tube 26 which is secured to the fiottom of the pan, the tube being slidable on the pipe 7 to bring the pan to the desired height below the burner and to thus regulate the rate of evaporation. A thumb screw 27 passes through a collar 28 and through the upper end of thetube to clamp the tube to the pipe and thus adjustably hold the pan 25 in the desired position. The pan in its lowest position rests on the upper edge of, the crossbar t. The pan has an upper inwardly directed flange 29 which serves to prevent water from splashing out when the heater is removed. During the operation of the burner the water evaporates slowly from the pan due to its location at such a consider able distance below the burner and thus the water does not have to be renewed frequently, while it evaporates sufiiciently fast to produce the necessary amount of moisture. The water pan keeps heat from the floor or table and prevents downward radiation of heat which would damage the floor covering or table. lit also protects the fiexible tube from the action of heat.

WV hen the device is, to be used for cooking the upper spreader 17 is removed, as before described, which exposes the flat upper surface of the lower cone 15 upon which the dishes may be placed. The lower spreader 15 is of course very hot and the heat passes therethrough to the things being cooked. By simply unscrewing the lower end of the burner from the pipe- 7, the burner and Spreaders carried-thereby may-be lifted b odily' from, the standard and the burner may be. screwed to the tip of a gas fixture 30 as indi= cated in Fig. 3. Obviously when thus applied the upper spreader 17 may be used or not, according to whether it is desired to heat the room or to cook. The upper ring 3 has a greater diameter than the upper spreader 17 andlying outside thereof acts as a guard to prevent persons or their garments coming into contact with the hot rim of the spreader.
