FLAT-IRON' HEATER.

Specication of Letters Patent.

Patented May 7, 191s.

Application filed I u1y 9, 1917. Serial No. 179,447.

This invention relates to stoves and furnaces, and more especially to tool heaters; and the object of the same is to produce a' device of this kind which burns coal orL other hard fuel, and is intended for heating flat irons,` although it may be used for cooking or other heating purposes.

The invention consists in the details hereinafter more fully described and claimed, and as shown in thedrawings wherein Figure 1 is a front elevation of this heater complete, one end of the door being broken away to show the interior construction.

Fig. 2 is a plan view with one endof the cover broken away,

Fig. 3 is an end elevation with the ash pan drawn out and laid aside.

Fig. 4 is a central vertical longitudinal section.

Fig. 5 is a central vertical transverse section looking toward the fastening device for the fire pot.

Fig. 6 is a perspective detail of the re pot removed.

Fig. 7 is a inverted. A

Mounted on suitable feet 1 is a casing which in its contour and structure comprises an ash pit 2 above which the casing is reduced in width t'o produce a narrow neck 3, and above the kneck the casing is again widened to kproduce a body 4 whose side walls may-converge slightly as shown in Fig. 3, and whose open upper end is provided with grating y 5 Isurrounded by an upstanding detail of one reducing element flange 6, and the latter is preferably also surrounded by an outstanding flange 7 Hinged at 8 is a cover 9 having perforations 10 in its top, and slidably mounted beneath said cover and carried by it is a damper 11 havinga handle 12 projecting from one end. What might be called the front side of the body is open, and hinged at 13 along door 14 (partly broken away in Fig. 1) and which when raised and closed is held in this position by means of la button 15 engaging a keeper 16. Within the neck 3 below the hinge line 13 of the door is mounted a longitudinally movable damper 17 which may be set to regulate the size of the inlet or draft openings 18 by means of its handle 19. Finally a bail 20v is provided, whose extremities are connected with the ends of the casing so that the entire device can be lifted and carried from point to point, and when not in use this bail is thrown back out of the way of the moving members or parts.

In one end of the ash pit 3 is an opening normally closed by a door 21 having a suitable catch 22, and when this door is opened an ash pan 23 may be slid into the pit or removed therefrom by its handle 24,

the pan being of 1such length that when it is in place ythe ash pit door 21 may be closed and latched so that the controlled by the dampers. Within the ends of the body just above the neck are brackets 25 carrying notched bearings 26 in which rest trunnions 27 projecting from opposite ends of a fire pot 28 loosely disposed within and nearly. filling although purposely made slightly smaller than the interior of the same for reasons which will appear. This lire pot underlies the grating and is open at its top beneath the same, its bottom is perforated as at 29 and provided with upstanding ribs 30 in the nature of grate bars extending longitudinally between the rows of perforations as seen, and by preference the interior is lined with metal to prevent burning out.

The shaker comprises a bar 31 pivoted at its rear end to the backY of the neck and having a handle 32 at its front end extending through a slot 33 in the neck just above the damper 17, and between its ends this bar passes through a fork 34 depending from the tire pot at about the center of its length, so that when the handle is moved to and fro within the slot the trunnions yof the ash pit slide in their slotted bearings and the entire structure is reciprocated longitudidraft is entirelythe body of the casing,l

fuel to replenish that burned and pass it down into the pan in the shape of ashes, the front door 14 is opened and the entire pot swung forward on its trunnions as its shape and size will permit. Pivoted at 35 within one end of the pot is a latch 36 having through its free end a pin 3'? which projects thence outward through an arcuate slot 88 in the end of the lire pot| and through a second arcuate slot 39 in the end wall of the casing, beyond which the outer end of the pin serves as a handle. rlhis last-named slot has at its rear end a depending notch 40 into which the handle drops when the lire potstands upright in its normal position and is housed within the casing. lt is obvious that by raising the handle out of this notch and moving' it forward through the slot 39, the open upper end of the fire pot is swung forward as its body rocks on its trunnions in a manner which will be clear. The same can then be charged with fuel in the shape of coal, coke, or other granular substance such as is designed to form the heating agent of this device. By means of the same handle the fire pot is then restored to its proper position and the front door closed and latched, and the device is ready for use.

F or the purpose of reducing the exposed area of the grating at times single flat iron is to be heate for instance, I employ a plurality of inverted cup-shaped or more accurately, box-shaped elements 50 as best seen in F ig. 7, each of which is of a size to t within the `flange 6 at one end of the same and to rest upon the grating, and when in place said element blocks out practically a quarter of the exposed surface at the top of the heater. l purposely make these elements cup-shaped as described and shown, in order that when in use their flanged sides may rest against the flanges (3 and their flat upper faces may constitute heating surfaces for throwing off heat into thc compartment or for cooking or warming utensils or .food if desired; and yet when these elements are both employed there is practically a half of the grating surface vet exposed and upon which two ordinary flat irons may be placed to receive the direct heat from the coals. From this it will be understood that 1 prefer to make the grating of such a size as normally to accommodate four flat irons, but in this respect 1 do not wish to be limited.

The lire having een started in the usual manner, its burning is regulated by prop erly setting the dampers, or perhaps the cover could be left entirely open until the fire was well under way. After the coals are aglow, the lower damper may be closed to check the draft, and the cover also closed and its damper also more or less closed. The device when only a may now be used as a heater for an ordinary apartment, and for warming d1shes, food, and the like. lVhen the upper damper is opened it is quite possible to cook upon the device. llhen the cover is opened so as to expose the grating, a higher degree of heat is available because tools such as flat irons and other articles can be placed on the grating and heated by direct contact of the flames from the coals. This is the purpose for which my invention is primarily intended, but I reserve the right to use it in any manner possible. From time to time the lire pot must be shaken, and the ashes fall into the ash pan; and on occasions the latter must be removed and emptied in a manner which will be well understood. From time.

to time also the fuel must be replenished within the lire pot ,in a manner already described. l do not wish to be limited to the shape, proportions, or materials of parts, and details are unimportant excepting as claimed below. f

lfVhat is claimed as new is l.
