Application fled June 4,
My invention relates to electrical heaters and particularly to automobile engine heaters.
An object of my invention is to provide a relatively sim le and compact automobile engine heater t at shall embody a minimum number of parts and that shall ermit of bein section.
A heater designated generall b thenumeral 11 comprises a perforated tu ular cas;
ing 12, a substantially closed'end cap 13, a
centrally apertured end cap 14, and an end cover 15. The tubular casin may be perforated in amp) manner, and is shown as eing provided with a plurality of circular openings 16' and square or lozenge shaped openings 17. While I have illustrated only a few of these respective perforations, it is to be understood that the entire surface of the casing 12 is provided with such openings. s The end cap 13 is substantiallysolid and of dish shape and is secured to one end of 12 by an suitable means, such as spot wel ing. A ook member 18 is provided, which may also be secured to the easportion. 12
ing 12 by spot welding.
he'end ca 14 is also of dish sha e and the riphera portion thereof may e spot wel ed to the other end of the casing 12. It is provided with a central aperture 19, the walls of which are punched outwardly to constitute a peripheral flan e portion 21. a
A heating unit is locate I within the easing 12 and comprises a single refractory resistor-supporting member 22 having a reduc'ed end portion, which is provided with a helically extending groove 23 in the surface thereof for receiving a resistor member 24 which comprises a helically wound resistor wire. I One end portion of the resistor-supporting suita le or desired 1927, Serial No. 196,482. V
member 22 is made in the form of an expanded collar 25 to provide a shoulder 26 which is in operative engagement with the outer edge portion of the flange 21. The end cover member 15 is of substantially cone shape, as is shown in the drawing, and is of such dimensions both laterallyand longitudinally of the heater as to tightly clamp the refractory resistor supporting member 22 in its proper operative position, as shown in the drawing, with the shoulder portion 26 against the edge of the flange 21 and with the outer end of the collar wedged within the cover member 15. A plurality of sheet metal screws 27 ex-- tend through the peripheral ortion of the cover-15 and through the en cap 14 to securely hold the cover member in its proper operative position against the cap, and to v the end of the collar portion 25, which terminal members may comprise machine screws 28 and 29 to which the respective terminals of the resistor 24 may be connected and to which may also be connected the twin conductors of a conductor cord 31, of the usual type. The conductor cord 31 has a knot 32 tied therein close to the inner end thereof, and a perforated disc 33 of a suitable electric-insulating material is located thereon and may engage a bushing 34 of electric-insulating material which is located within an end opening in the cover member 15, and through which the cord 31 extends. A screw connecting plug 35 is mounted on the other end of the conductor cord 31 to permit of connectin the heater to a suitable source of supply of e ectric energy.
The refractory resistor-supporting member 22 is a unitary member and has the record, after which t e cord may be pushed through the bushing 34 located in the cover member 15, which cover member may then be located in its proper operative osition against the end cap 14 and secure thereagainst by the sheet metal screws 27 oeyiemy invention hu.

Various modifications may be made in the device embodying my invention Without departing from the spiit and scope thereof, and I desire, therefore, that only sveh limi- Cations shalt be placed thereon as are imposed the prior art or are set forth in the appended c taim.
I claim my invention:
In an air heater in combination, a using an apeitiired end cap therefor, a refractorysupporting member having one portion extending through the aperture into the 035i 21g VICTOR G. VAUGHAN.
