ELESTRIC HEATER.

ysimplicity and cheapness with respect to the frame construction and by new and improved means fo supporting the heating element in the frame of the device, said heating element comprising a coil of ywire which is passed back and forth through ing-AVA sulatizg supports mounted within the frame,

said supports extending upwardly through a reflector plate ,underwhich the bases of the supports are clamped-r. Other improvements will be evident in the rdetails of the device.

The invention may be embodied in various forms, one form being shown in the accompanylng drawings in which Figure 1 is a side elevation of the heater. Fig. ,f2 is a top Ulan view. Fig. 3 is a sectiononthe line 343 of Fig. 2. s i

Referrirfr specifically to the drawings, 6

y indicatesa bottom plate having a depending flange 7 around its outer edge, and this is mounted 0n legs 8 whlch are secured to the flange .7 at the corners. A9 1s a frame made of' a single piece or strip of metal the ends 4 of which are butted together at one end of the device as indicated at 10, and this frame is provided at its lower edge with lugs 11 which are fitted through slots in the plate 6 and upset thereunder, as show-n in Fig. 3. v

Fittingwithin the frame 9 is a reflector plate 12 the upper surfacepf which is .pol-

, ished, `and this plate is rprovided with a plurality @t rows 0f slots atdl' through which extend upright posts or standards 14 projecting from the bases 15 of the insulating elements. porcelain or other suitable insulating material, and it will be noted that the bases 15 thereof are confined between the bottom plate 6 and tho rciiectorlplate 1.2, these two plates being fastened together by screws 16 extending through the same. This assembly is very cas to make and the insulating elements are rmly hel in position by the posts specification of Letter: Patent.

These elements will be made of Patented Dec. 21, 1920.

Application filed June 25, 1920. Serial No. 391,722.

extending through the slots 13 and the enlarged bases thereof being confined between the plates, and they do not have to be otherwise attached or secured in place, and fur-l thermore the construction provides an air space 17 between the two plates. The heating element or coil consists of a long wire helix indicated at 18|which is threaded back and forth through holes 19in the osts 14, down one side ofthe frame and up the other, the ends being cohnected to the binding posts 20 to whic the conducting cords 21 are connected through an insulating bushing at 22 in the bottom plate 6. T.andles 23 may be pro .'ided at the ends of the frame, and a grating 24 sets on top of the frame 9 where it is secured by the ears 25.

The main sup orting parts of the heater com y rising the p ates 6 and 12, the legs 8 and the rame 9, are made of sheet metal, and can be stamped out at small cost. The insulating elements are small and readilymolded to shape, and in assembling the parts the frame 9 is readily fixed to the plate 6, and the insulating elements then set in place on the plate and the reflector plate 12 dropped into 0- sition and fastened by the screws 16, t us clamping the parts together, after which the heater coil is threaded through the osts and connected to the terminals, ready or use.

While I have shown and described this particular construction it is evident that the same is capable of various modifications and I do not wisn to limit myself' in the construction of the same further than is required by the state of the art or that which comes within the scope of the appended claims.

1. An electric heater comprisin a stand having a bottom plate, a reflector plate above the same, insulator elements clamped between the plates and having posts projecting through said reflector plate, and a heating element supported by said posts, above the reflector plate;

2. An electric heater having a bottom plate, a reflector plate, insulator elements having bases clamped between said plates and posts projecting through the reflector plate, and a heating element supported by said posts.

3.7An electric heater having a 'Lottum plate, a reflector plate, individual insulator elements having bases confined between said plates and posts projecting through the rethe reflector plate. 5. An electric heater comprising a stand having a bottom plate, a frame upon said plate, a slotted reflector plate fitting Within said frame, insulators having enlarged. bases confined between said plates and upright vposts projecting through said slots, fastening means between the plates, to hold the reflector plate andiwnsulators in position, and a heating element supported by said posts.

In testimony whereof, I do alx my signature in presence of two witnesses.
