ELECTRIC HEATER.

Specification of Letters Patent. Patented June to, 1913.

Application filed October 30, 1912. Serial No. 728,615.

To all whom, it may concern Be it known that I, Gnonon E. Snanrn, citizen of the United States, residing at Steubenville, in the county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Electric Heaters, of which the following is a speciflcaerally, the'construction and arrangement. of.

the parts of a heater to the end that the eflicienc'y and durability of the same may be increased, all of which will fully appear from the description hereinafter given.

The invention consists in certain novel features which will be particularly pointed out in the claims following the description. 'The invention is illustrated in the accompanying drawings, in which:

Figure l is a perspective View of a heater embodying my present improvements; Fig. 2 is a vertical section through the heater extending from front to'the rear thereof Fig. 3

is a rear elevation of the lower portion of the heater; 'Fig. 4 is a horizontal section taken on the line 4-4: of Fig. 2; Fig. 5 is a detail perspective View of the lower portion of the heater, Fig. 6 is a detail perspective view of. a brace employed to reinforce the upper end of the reflector.

In the particular embodiment of the in vention illustrated, the fmain frame comprises side members or pilaste'rs 1 and a crown or head 2 extending between the said side members or pilasters, the said members being preferably channeled castings. The head or crown 2 is shown provided wit-h panels 3 which may be of any desired ornamentation. The head or cross bar 2 is.constructed at its lower edge with an inwardly and downwardly extending rabbet,.shoulder or flange it whichreceives the upper edge of a slotted bar or grille 5, said bar orgrille being secured to the head bolt 6 inserted through its upper edge and the flange 4 of the'liead and being secured at its ends by bolts 7 passed through offsets S of the pilas- SllQd OI'- convenient manner.

ters 1. The lower edge of this grille or slotted bar is extendedinwardly and down wardly to provide an overhanging shoulder, rabbet or flange 9 which flts over the upper edge of a hood or crown 10 which is preferably cast integral with the pilasters and extends between the same. This exact arrangement of these parts, however, is not essential and the details of the same may be varied at will. Between the lower ends of the pilasters 1 is a slotted bar or grille 11 which constitutes a base for the heater, and may be secured to the pilasters, in any de- A transverse supporting bar or shelf 12 is disposed-in rear of the pilasters and the upper portion of the grille or base 11, and this cross bar or shelf 12 is formed integral with the legs 13 which fit against the rear faces Of the pilasters between the flanges thereof and are rigidly secured thereto by bolts 14, the ends of the shelf being upturned, as shown at 14?. Secured to the rear face of the head or cross bar 2 is the flange 15 at the upper end of a drum or casing 16 which extends rear- \vardly and downwardly from thesaid head and then extends downwardly parallel with the front plate or main frame, the drum or casing having its lower end in the same horizontal plane as the lower ends of the pil'asters and the lower edge of the base or grille 11. The side walls 16"of the drum or casing extend to and are secured to the piles.

ters so that a heating space between the drum and the front frame is provided, the edges of said side walls being extended laterally above the legs 18, as shown at 16". The lower edge of the drum provides-an eX- tended supporting base for the heater so that, when the same is set up for use, it will be steady and will not easily topple over.

e l-reflector 17,preferably of highly hurnished sheet copper, is provided between the drum and the front; frame and is'preferably shaped to provide a number of cells 18, each adapted to fit around an electric lamp bulb, as illmtrated most clearly in Figs, 1 and 4. The upper end of the reflector is open, is shown'clearly in F ig. 2, and'the back of the reflector is in spaced relation to the back of the drum or casing. The lower end of the reflector is covered by a bottom plate 19 whichv extends to the upper edge of the base or grille 11 and is reinforced by a supplemental plate 20 rigidly secured to the lower end of the back wall of the reflector and extendinglacross the drum and bearing against the side walls thereof, as shown most clearly in Fig-"4,. so that the refle'ctor'will be rein forced and will not tend to lose its shape. Buckling of the drum is also prevented by the employment-ofthis reinfoicing or sup plemental bottomplate. Thefront .edg'es of the bottom-19 and the supplemental orreinforcing plate 20' are bent downward, as at 20 and secured j to 'the inner face of the f grille 11 at the upper edgether'eof, the ends.

of the plate l9 .be1ng extended over the upturned ends 14 of the'shelf 12, as shown at 20 To still further reinforce the reflectors and maintain the shapeofthe same, I provide the supports or spacing plates 21 which are secured rigidly .to the back wall of 'the drum and "extend forwardly therefrom to engage between the convolutions-ofthe reflector, as shown clearlyin Fig. fl, to thereby prevent collapse of the'reflector. A brace 22 4 is' alsoprovided at the upper end o'flthe reflector,'said;brac'e consisting of a flat bar rigidly secured to theupper'end ofeach cell -of the reflector and having its ends turned any other convenient manner and they are connected by conductors-26, as will be readily understood. These sockets may be of any ordinary standard type and the details of the same are not illustrated 'as they formno part of my presentinvention. The

electric lamp-bulbs 27 are inserted'through openings provided therefor in the bottom plate 19and the reinforcing plate 20 and en gage the sockets in the usual manner, the openings through which the stems of the bulbs pass'and the sockets being so dlspos'ed that the bulbs will occupy a concentric relation to the cells of. the reflector. A switch 28, or controlling buttons, may be placed at any convenient point to permit the current to be tu'rnedon or cut off, thecentral point of the lower grille being generally preferred.

l/Vhen the current has been turned into the lamps, the heat generated by the same will be thrownoutwardly by the reflector and at the same time airwill pass into the openings of the lower grille or base 11 and flow under the bottom plates of therefiector and I. then upwardly-between the reflector and the drum or casing, "finally escaping through the openings of the upper grllle or-across the open upper end of'the reflector and under the hood if thegrille be notemployed. I thus effect heating by radiation as well as by circulation so that the temperature of the-room is quickly raised to the desired de-' gree. The drum and the reflector are preferably constructed of sheet metal so that the heat will be readily given off and buckling .the desired results;

of these parts iseffectually prevented by the bar 22,1110 spacing plates 21 and the reins forcing bottom plate 20, as will be readily understood. The lamps and their sockets will be effectively supported by the shelf 12 so that disarrangement or damage to the-- conductors will be prevented, inasmuch as the frame, drum and the bottom 19 of the reflector entirely inclose the shelf vand the sockets. otherwise become useless, it may be readily withdrawn from the socket, the open upper end 'of "the reflector permitting sufiici'ent longitudinal movement of the lamp for it to be disengaged from the socket, and the opening above'the lower grille 11 and between the same and the crown or hood 10 being ample for the withdrawal of thelamp. The de- VICQLS very'snnple inits construction and .the arrangement of. its parts and may be easily moved from point to point so that it maybe set: up and used at the place in a room where it' will beinost' apt to produce It will be readily noted that the several securing bolts ar'oaccessible so that the face 'plate ormain frame may be removed fromthe drum, the reflector and the supporting shelf, without necessitating a disconnection ofthe'reflector from the drum or a sepa'ration of the reflector and the shelf. The drum'may also be removed f'rom'the fdce plateand the reflector without requiring the reflector to be separated from the face plate or from the shelf so that a damaged part maybe replaced withoutnecessitating the provision of'an' entirely new heater and'th'e substitution of a new part for any part which is still useful. It'will also be noted that, while the deviceis portable and may be placed anywhere in. a room, it may be set int a fire-placeso asto completely fill the same a nd impartan ornamental finish to the opening. The spacersand the bar 22 effectually prevent suclr buckling of the reflector'as will obstruct the passage between the reflector and the drum and hold the upper end of the reflector in proper spaced relation to the drum and the face plate; Moreover, thespacers create a plurality of fines between the reflector and the drum so that the air entering the lower grille of the Should a lamp be burnt out or face plate will be caused torise' positively through the space between the drum and the reflector and the creation of laterally flowing currents will be avoided.

Vv hat' I claim is:

1. The combination of a main frame hav-' jecting upwardly through said bottom plate in front of the reflector.

2. The combination of a main frame having a central opening therethrough and having upright side members, a reflector fit-ted to the frame and disposed in rear of the said opening, a support for the lower end of the reflector detachably secured to the main frame, and a drum inclosing the reflector and spaced from the same throughout its extent, said drum having its upper end secured to the rear face of the frame at the upper end thereof and its side walls bearing against the side members of the frame and provided with lateral extensions secured to said side members above the said support:

3. The combination of a main frame having a central opening therethrough, a shelf arranged in rear of the main frame and below the said central opening and provided with up-turned ends, legs rigid with said lip-turned ends and secured to the rear side of the main frame, a reflector having a bot tom plate extending between the ends of the shelf, a reinforcing plate secured to the bottom of the reflector and extending between and fitting over the rip-turned ends of the shelf, and a heating member supported by the shelf and projecting upwardly through the bottom of the reflector and in front of the main portion of the same.

4:. The combination of a frame having an opening therethrough and having upright side members, a shelf arranged in rear of the frame below the opening through the same, said shelf having upturned ends and provided at the front edges of its ends with legs bearing against the rear face of the side members of the frame and secured thereto,

and a reflector in rear of and spaced from same, said shelf having upturned ends and provided at the front edges of its ends with legs bearing against the rear faces of the side members of the frame and secured thereto, a reflector in rear of and spaced from the frame and having a bottom plate resting on and fitting over the upturned ends of the shelf, the front edges of the reflector and said bottom plate bearing against the rear face of the frame at the sides of and below the opening through the same, and a drum inclosing the reflector and spaced from the same throughout its extent, said drum having its upper end secured to the rear face of the frame at the upper end thereof and its side walls bearing against the side members of the frame and provided with lateral extensions secured to said side members above the said legs.
