HAND-GRIP EINERGIZED ELECTRIC CIGARETTE LIGHTER Filed Feb. 25, 1954 INVENTOR.

Z, PVT JZEA ZF BY Z United States Patent HAND-GRIP ENERGIZED ELECTRIC CIGARETTE LIGHTER Ewald W. Terney, Mineola, N. Y. Application February 25, 1954, Serial N 0. 412,423 6 Claims. (Cl. 219-32) This invention relates to electric cigarette lighters, and more particularly to that class of lighters wherein a coiled heating element is energized to red heat upon the closing of a switch.

One object of the invention is the provision of an electric cigarette lighter containing a glow element, having means whereby a circuit through the element is automatically energized when the lighter is grasped in the hand. A lighter embodying the features of this invention may be used in an automobile, in the home, or in any other suitable situation, either in portable or stationary form.

Another object of the invention is the provision of an electric cigarette lighter enclosed in a flexible housing or body having means within the housing whereby a circuit through the glow element of the lighter is automatically closed when the lighter is grasped in the hand, and is automatically opened upon release of the lighter.

The above broad as well as additional and more specific objects will be clarified in the following description wherein characters of reference refer to like-numbered parts in the accompanying drawing. It is to be noted that the drawing is intended solely for the purpose of illustration and that it is therefore neither desired nor intended to limit the invention necessarily to any or all of the exact details of construction shown or described except insofar as they may be deemed essential to the invention.

Referring briefly to the drawing,

Fig. 1 is a perspective view of a cigarette lighter constructed along the lines of this invention, showing the same as it may be applied for use in an automobile.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a section view taken on the line 33 of Fig. 2.

Fig. 4 is a perspective view of the lighter showing how the outer shell or housing is pressed inward, to close a circuit through the glow element, upon grasping the lighter.

Fig. 5 is a sectional view taken on the line 55 of Fig. 4.

Fig. 6 is a wiring diagram.

Referring in detail to the drawing, the numeral 10 indicates the electric lighter as a whole, comprising two shells 11 and 12, preferably cylindrical and concentric. The inner shell or tube 11 is of relatively rigid insulating material, and the outer shell or housing 12 is of relatively yieldable or flexible insulating material. Flanges at the ends of the inner shell, shown at 13 and 14, serve to space the outer shell at a distance from the inner.

At or near the top of the inner shell 11 a glow element, of standard construction, shown at 15, is mounted, in the usual manner. At the bottom of the shell 11 a closure disc 16 is provided, having an opening for the passage therethrough of a two-conductor cord 17.

At least one, and preferably two or more, circuit-closing members, or switches, 18, are mounted in longitudinally as well as circumferentially spaced positions within the cylindrical space 19a between the two shells.

In Fig. 2 but one such switch member 18 is shown; how

2,728,844 Patented Dec. 27, 1955 ever, three additional ones are shown in broken lines in Fig. 4. The exact number of such switch members to be used is optional so long as the object of the invention is attained.

Each switch unit 18 comprises a relatively long resilient strip 19 secured at its midpoint by a screw or the like 20 against the inner shell 11, the screw passing through the shell, and with the strip lying in a plane at right angles to the axis of the shell. Thus each strip provides two resilient arms 21 which are arched outward so that their free extremities are very close to or in contact with the outer shell 12. At each end of the strip 19, in the same plane as the strip, a stationary contact 22 is secured against the shell 11 by a screw or the like 23 also passing through the shell, with the contact underlying the extremities of the arms 21. Thus when either arm 21 is pressed inward toward the shell 11, it will engage the adjacent contact 22. However, in order that closure of the circuit through the glow element be effected whenever the lighter is grasped, and since the pressure of the fingers or the palm of the hand may be applied to the outer shell 12 at different points or areas at diflerent times, it is desirable that at least one additional switch member 18 be provided, situated in the same manner as that just described, between the two shells, but at a distance longitudinally as well as circumferentially from the former, as exemplified in Fig. 4. Assuming that four such units 18 are provided, it is apparent from the wiring diagram of Fig. 6, that the closing of any single switch end or pair 2122 of any switch unit 18 will close the circuit through the element 15 from a source of supply delivered at the terminals 24.

A partition 25 may be provided near the lower end of the shell 11, with binding posts 26 extending therethrough, for attachment on the lower side, of the ends of the wires of the conductor 17 and on the upper side, of the leads such as that shown at 27, from the various switches and the element 15, all as indicated in the wiring diagram.

The conductor 17 may be permanently plugged into a socket, not shown, in or near the dashboard when used in an automobile, or it may be wound on a self-winding reel, not shown, of any standard type, connected to the electric supply source. An eyelet 28 is preferably secured to the rigid shell 11, to extend diametrically through the shell 12, to serve as a means for hanging the lighter on a hook, as indicated at 29 in Fig. 1.

Further, the lighter might be used indoors, similarly hooked up to an electric supply source and adapted to be supported on a hook positioned at any convenient place, as, for instance, on a wall, on the edge of a desk or table, etc. And finally, the lighter might also be mounted on a stand or upright, not shown, and thus be movably seated on a table, desk or the like.

Thus, with a lighter constructed along the lines of the present invention, the circuit is at all times open except when the lighter is grasped, and whenever and during the entire time that it is grasped or held, the circuit is closed and the element energized. Thus no thought or action is required by the user other than the mere picking up of the lighter, when he wishes to use it, and the mere putting it back where he got it, when he has finished with it.

Obviously, modifications in form or structure may be made without departing from the spirit or scope of the invention.
