To all whom z't may concern:

' .Be 'it known ^that I,-"HENRY Dione, a, citi-I New .York,y have invented new and useful Improvements in Electric Heaters, oi which This invention relates to electric heaters. .l

4An object 'of this invention is to provide an electric heater wherein the 'resistor when glowing is visible throughout practically its entire length.

Another olo]ectV is to .provide an electric heater having the resistor thereofl so mount,

fed that practically the entire surface of the Aresistor throughout its length is effective to furnish light.

Another obj ect assembled. v

The electric heater embodying this invention is particularlyuseful whe'n mounted in. reflectors of radiant heaters but may be employed elsewhere. An embodiment trated in the accompanying drawings in lie the insulating plate 6. The resistor is secure-d to the insulating plate by means of rivets 7 passing through apertures in the insulating plate and through the innerloops of the resistor. The ends ,of the rivets are expanded to-iirmly clamp the resistorto the insulating plate at intervals.

The heater may means of pins secured to each end of the insulating plate 6. These pins extend forwardly from the reflector 10 and support the heater which is thereby spaced a short Y distance from the surface of thereflector. The endsof the resistor 5 may be connected with , conductors 12 and 13 leading to a source of electricl current.

is topi-'Ovide a simple electric heater of few parts easily and quickly ofthis invention is illus-v i in a zigzag path and formed about be mounted in a reflector' The heater may be mounted in the reiector with the'resistor 5 mounted upon the front .or back of the insulating plate. lAs illustrated, the resistor-is mounted upon the front of this insulating plate, When the resister is connected with the source of electric current and is glowing, practically the entire length of theresistor is plainly visible. Since the resistor 'is mounted on a transparent support, the light emitted from the resistor may readily pass through the transparent support. It is then reflected by the surface of the refiector,` thereby increasing the amount of light furnished by the heater. v Obviously otherstructures may be devised "which will embody the invention herein set forth.

What is claimed is: 1.',An electr-ic heater comprising a transparent insulating base and a -resistor mounted thereon. 2. Anf electric heater comprising an insulating plate,.a resistor arranged in a zigz'ag path and formedabout the margin of 'the insulating plate with inwardly extending loops of the resistor overlying the plate,

. and means for securing the resistor to the front elevation of a re-iector 3. An electric heater comprising a transparent insulating plate, a. resistor arranged the m-argin of the -plate with inwardly extending loops of the resistor overlying the plate, and means engaging some of the loops atthe baltse thereof for fastening the resistor to the p am.

4. An electric heater comprising a transparent-insulating'plate, a resistor arranged in azigzag path and formed about the margin of .the plate with inwardly extending' loops of the resistor overlying the plate, and rivets engaging some of the loops at the base thereof for fastening'the resistor to the plate.

5. An electric heater comprising a transparent insulating' plate, a resistor arranged in a zigzag path overlying the plate, and means engaging the resistor at intervals for attaching the resistor to the plate.

In witness whereof, I have hereunto subscribed my name.
