Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed September 22, 1915.- Serial No. 51,908.

To alt whom t may concern Be it known that I, MARK G. RAY, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Heaters, of which the following is a specification.

This invention relates to heaters, and has special reference `to heaters intended to burn charcoal as fuel and adapted for use by tailors and in camps.

More specifically stated, the object of the invention is to provide a heaterwhich may be produced at a low cost and in which the ash pan, the grate, and the body will be connected in a simple vand effectual manner.

The stated object, and such other objectsl as will appear incidentally in the following description are attained in the use of a heater such as is illustrated in the accompanying drawings and the linvention resides in certain novel features which will be particularly pointed out in the claim following the description.

In the accompanying drawings: Figure 1 is an elevation of a heater embodying my present improvements; Fig. 2 is a vertical transverse section of the same; Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 1; Fig. 4r is an enlarged detail section showing the manner of protecting the bottom of the ash pan; Fig. 5 is a detail perspective view of one of the legs; Fig. 6 is an enlarged section taken on the line 6 8 of Fig. 1; Fig. 7 is a detail perspective view of a portion of the door to the ash pan; Fig. 8 is an enlarged detail section showing the manner of supporting the grate and connecting the grate, the body, and the ash pan; Fig. 9 is a detail' horizontal section taken on the line 9-9 of Fig. 1.

1n carrying out my invention, I employ a sheet metal body 1 which is bent to form a structure rectangular at its lower end or base and having its open upper end forming a horizontally disposed circle, said upper end having fitted thereon a flaring ring 2 provided with openings 3 in its wall. The lower edge of the body 1 is carried horizontally outward forming a shelf, as shown at 4, upon all four sides and then bent upward, as shown at 5, to provide a vertical flange or rail. rllhe ash pan consists primarily of a rectangular sheet metal plate which forms the bottom 6 of the ash pan and has its side portions turned upwardly, as shown at 7, to

provide the side walls of the ash pan. These side portions 7 may be carried to any desired height, according to the size of the heater,

and the plate is then bent sharply outward,

as shown at 8, to coact with the horizontal portion t of the body, and from the outer edge of the horizontal portion 8 the plate is bent upward, as shown at 9, and then doubled on itself, as shown at 10, so as to fold over and engage the opposite faces of the vertical flange or rail 5 of the body. The grate consists of a sheet metal plate 11 having its edges fitting between the horizontal portions 41 of the body and the horizontal portions 8 of the ash pan, the edge of the 4grate abutting the upstanding portion 9, as

shown in Fig. 8 or being turned between the portions 5 and 9 as shown in Fig. 2. When the portions 9 and 10 of the laterally eX- v tended portions of the ash pan are pressed together so as to be clamped upon the rail or flange 5, the body, ash pan, and the grate will be positively and eifectually secured together in a very simple manner. By referring to Fig. 3, it will Abe noted that the corners 11 of the grate extend beyond the end edges of the body and of the ash pan so that u a continuous shelf is provided around the entire heater.

throughout its area so that a draft will be permitted to support combustion and the ashes or consumed fuel may drop into the ash pan. lThe side walls 7 of the ash pan tom of the same and is held in place by tongues 15 struck from the side walls of the ash pan and bent down upon the asbestos as shown most clearly in Fig. 4. 1t will also be noted that this construction provides an additional opening 16 to admit air into the ash pan and thus support combustion. One side wall of the ash pan is constructed with a door opening 17 at the lower edge of which is hinged a door 18. This door 18 is provided at its end edges with wings 19 which extend into the ash pan and are constructed with flanges 2O at their inner lower edges which are adapted to impinge against the inner edges of the side Wall when the door is opened and thereby limit the outward It will also be noted that the grate is constructed with perforations 12 llO . opening movement of the door, as will be readily understood. The upper edge of the door is also constructed with a rib or flange 21 projecting upwardly and outwardly and adapted to engage against the outer surface of the side wall at the upper edge of the door opening when the door is closed, as shown in Fig. 6, and thereby limit the inward movement of thel door. It will thus be seen that the door cannot be dropped so far that it cannot be conveniently reached by the user when it is to be closed, nor can it be pushed into the ash pan to such an ex- I tent that it cannot be conveniently reached when it is to be opened. It will also be noted, upon reference to the dotted lines in Fig. 6, that the body of the door may be utilized as a chute when it is desired to withdraw from the ash pan the ashes or other' sediment collected therein. A knob or other handle 22 will, of course, be provided upon the door.

I provide a pivotally mounted bail 23 by which the device may be easily moved from place to place, and to each corner of the ash pan I secure a leg 24 by which the device will be supported above the ioor of a room or above the ground, so that an air sp ace will be provided below the ash pan to counteract the liability of' the ash pan being unduly heated. The leg 24C is constructed of sheet metal bent to present upper attaching wings 25 which are disposed at a right angle to each other so as to iit against the meeting sides of the ash pan. The sheet metal plate from which the leg is formed is eut, as indicated at 27, at the lower edge of each attaching wing and the portions of the plate below each eut or incision is turned inwardly to provide members 28 adapted to project under the bottom of the ash pan whereby a tubular post or support is formed, the up- A per Aedges of the members 28 fitting directly against the bottom of the ash pan so as to positively support the structure. The sides of the ash pan are cut away at the corners of the same, as shown at 26, and the edges of these cut-away portions are doubled outwardly on themselves to engage and interlock with the edges of the leg wings 25 which are doubled inwardly on themselves as shown in Fig. 9.

VIt will be noted from the foregoing description, taken in connection with the accompanying drawings, that I have provided a very simple heater which may be manufactured and sold at a low cost. The device is light so that it may be easily carried from place to place and is, therefore, especially adapted for use by campers. The fuel is placed through the open top of the body and is supported by the grate so that the heat given out will be received directly by the walls of the body and will also tend to pass off through the top of the same. As the top is open, a cooking utensil may be supported directly by the same over the fire and food, consequently, readily cooked. The pan or other cooking utensil will rest on the upper edge of the ring 2 and the heat escaping through the openings 3 will play against the bottom and sides of the pan. Moreover, the draft is not obstructed so that the fire may be easily maintained. The peculiar construction illustrated and described whereby Vthe grate is supported and the body and ash pan connected, furnishes a very eilicient shelf and rail against which the lower ends of irons may be placed with the bodies of the irons resting directly against the body of the heater, and as the heat from the fire is received directly by the wall of the body, it will be readily seen that the device furnishes a simple and economical heater for use by tailors or laundriers. It will also be noted that the fuel is inclosed and the ashes cannot drop upon the ioor of a room nor upon any loose conbustible material which may be lying near the heater so that a room may be heated without danger and in an economical manner.

Having thus described my invention, what is claimed as new is:

In ay heater of the character set forth, the combination of an ash pan having an outwardly extending shelf along its upper edge. a grate resting on said outwardly extending shelf, and a body having an outwardly extending shelf around its lower edge resting upon the grate over the outwardly extending shelf of the ash pan, the outwardly extending shelves of the body and the ash pan being clamped together to secure the grate.

In testimony whereof I aiix my signature.

MARK e. RAY. [1.. a]
