ELECTRIC CIGARETTE LIGHTER.

Application filed March 5, 1927. Serial No. 172,988.

the-form of a plug which may be screwed into any standard electric socket.

Another object of the invention is to provide such a unit of novel and compact construction such as will permit ready dismantling of the unit for repairs or replacement of worn parts and which will provide relatively longer life and longer service without necessitating repairs.

The above and other'objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings, Fig. 1 illustrates a portable electric socket equipped with my lighting unit.

Fig. 2 is a longitudinal cross-Sectional view oi the unit.

Fig. 3'is a perspective View of the body of the unit;

Fig. 4 is a perspective view of the frame upon which the electric heating coil is wound.

Referring in detail to the drawings,.the

portable handle having a standard electric socket 11 thereon, .and the usual push button switch 12,13. The body of the unit is shown at 14, and is preferably made of soapstone, although any dosirable non-conducting material may be used. A rectangular'channel 17 passes longitudinally through the body 14;, as well as through the neck 15 de ending from the body. This neck is screwreaded in the usual way, and a brass shell 16, similarly threaded, is secured to the outside of said neck.

The lower edge of the shell 16 is flanged inwardly, at 19, and this edge is imbedded in a glass inverted dome 18 which serves as the base of the plug. The usual contact 20 is secured in the center of the dome 18. An opening 24 is provided in one side of the neck through which a wire may pass to be soldered to the shell 16.

The upper portion of the body 14 is shaped somewhat in mushroom fashion, and a flange 21 is provided about the lower edge of the umbrella of the mushroom. A shell 22, of substantially the same confirmation as the upper portion of said body, is snugly attached thereto and secured at the bottom by having its lower edge 23 bent around the flange 21. The shell 22 is preferably made of brass.

At the top of the body 14, on the sides of the rectangular channel 17, square-cornered grooves 25 are cut, adapted to receive similarly shaped shoulders 26 of the 'coil frame 27. This frame is a unitary moulded.

member, having a core provided with spaced apart flanges 28 which form grooves 29 in which the coiled heating element 31 is wound. One terminal of the heating element is soldered to the contact 20, and the other to the shell 16 through the opening 24. A

perforated mica plate 32 is placed over the top of the heating element and kept in place by the inwardly flanged edge of the shell or cap 22.

From the above it is obvious that when the unit is screwed into an electric socket and the switch turned on, the element 31 will receive the full voltage of the line, and this element is so designed that it will be heated to a red heat upon the a plieation of said voltage, as is usual in this type of lighter. In order to light a cigar or cigarette with the device, the tip of the article is held against the mica plate 32. This plate serves to keep the article' from actual contact with the element 31, as it is well known that through repeated contact between the article and the element, bits of tobacco becomeseparated from the article and cling to the ele- 'ment. Eventually these bits form into a thick mass which may completely insulate the top of the element so as to prevent accomplishment of its purpose.

In the event that the unit require repairs or replacement of parts, the fingers 23 are bent back and the cap 22 removed. This permits withdrawal of the coil frame and coil, and the latter may then be repaired and readily replaced.

Obviously changes, in form and construction may be made in the invention as above described without departing from the scope of the appended claims.

What is claimed is as follows:

1. A unit of the class described having a mushroom-shaped body with a rectangular channel passing longitudinally therethrough, rectangular grooves in the top of said body communicatingwith said channel, a removable member having shoulders adapted to register in said grooves, and means on said member for receiving a heating element thereon. I

2. A unit of the class described having a mushroom-shaped body with a rectangular channel passing longitudinally therethrough, rectangular grooves in the top of'said body communicating With said channel, a removable member for supporting an electric heating element comprising a core and a plurality of spaced-apart rectangular flanges on said core, said member having rectangular shoulders extending therefrom adapted to register with said grooves to support said member in hanging position Within said channel.

3. A unit of the class described having a mushroom-shaped body with a rectangular channel passing longitudinally therethrough, grooves in the top of said body communicating with said channel, a threaded shell sur rounding part of said body, a removable member comprising a core and a plurality of spaced-apart rectangular flanges on said core, a cap covering the top of said body, a heating coil Wound about said core between said flanges, said member having a rectangular shoulder extending therefrom adapted to reverse with said grooves to support said member in angular position within said channel, an insulated contact at the bottom 01 said body, the terminals of said coil bein connected respectively to said contact and said shell, and a plate of non-conducting and heat-resisting material secured between the top of said coil and said cap.

In testimony whereof I afiix my signature.

STEPHAN WAGNER.
