E LE CIRIC LIGHTING DE VICE Application filed October 28, 1907.

To all whom it may concern:

Be it known that I, Josnua T. FISK, a citizen of the United States, resident of Rochester, county of Monroe, and State of New York, have invented a new and useful Improvement in Electric Lighting Devices, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates toelectric lighting devices adapted for use as a cigar-lighter to enablea smoker to light a cigar while in rapid motion or otherwisefbu t it is applicable for use as a cigar-lighter on the counters of stores or other places.

The invention furthermore relates par ticularly to that class of devices shown, described and claimed in the application Serial No. 393,418, filed September 17, 1907, by Clarence lVheeler, and consists in an arrangement of parts which while in its general features is identical with the invention of said Wheeler, yet contains certain other improvements diifering materially therefrom.

The said improvements are hereinafter fully described and specifically set forth in the claims.

The object of said invention is to increase the efficiency of the device by decreasing the time which is ordinarily consumed in raising the resistance wire to the required temperature, increasing the degree of heat produced by the incandescence of such wire, without increasing the consumption of current.

The annexed drawing and the following description set forth in detail, certain mechanism embodying the invention, the disclosed means constituting but one of various mechanical forms in which the principle of the invention maybe applied.

In said annexed drawing :Figure 1 represents a perspective view of a lighting device embodying my invention, showing its parts arranged for use as a cigar lighter. Fig. 2 is a greatly enlarged axial sectional view through the front portion of the device. Fig. 3 is a cross-sectional view taken on line 33 of Fig. 2. Fi 4 is a similar view taken on line 4.4t 0 Fig. 2; and Fig. 5 is a view in side elevation of the front portion Specification of Letters Patent.

of the device, showing an electric lamp provided with a reflector connected thereto.

Like numerals of reference, refer to corresponding parts throughout the different views of the drawing.

The device illustrated shows a form of device to which my invention is applied, which may also be used as an illuminant.

The reference numeral 10 designates the body or hand piece of the lighting device, which may be made of any suitable size, form and material, but preferably cylin drical in shape and of wood or hard rubber. This body or hand piece is provided with a longitudinal bore 11, which is divided near its front end by means of a transverse partition 12, thus forming two compartments 13 and 1 1 of the bore for the reception and operation of the various parts of the device, as will be hereinafter explained.

Located in the compartment 1 1 of the bore 11 is an internal screw-threaded metallic socket 1? which rests at its inner end on a suitable block or plug 16 interposed between said socket and the front surface of the partition 12, as is clearly shown in Fig. 2 of the drawing. This plug and the partition 12 are apertured for the reception of a terminal 17, to one end of which is connected one of the conductors 18 which are extended through the rear end of the hand piece 10 forwardly, and are connected at their other ends to a battery or other source of electric supply. The other conductor 18 is also extended through suitable openings in the partition 12 and block or plug 16 so as to contact or be electrically connected at its front end with the metallic socket 15, as is clearly shown in Fig. 2 of the drawing.

Located in the socket 15 is a stem or stub shaft of a removable cup 19, which is provided in its wall with a push-button 20 to coact with a contact spring 21 which is located in the cup, as shown in Figs. 2 and at of the drawing. The stem of the cup 19 consists of an externally screw-threaded metallic portion 22, which is hollow and of suitable length to extend near the bottom of the socket 15 when screwed therein, and of insulating material 23, such as fiber, which is interposed between the screw-threaded extension 22 and a metallic rod 2%, usually of brass, which rod has in its front end a screwthreaded socket 25, and its other or rear end exposed to contact with the terminal 17 to which one of the conductors is attached.

Removably located in the cup 19 is an i 'niter carrying cup 26, which has its front end open and its rear end closed by means of a disk or plate 27, of fiber or other suitable material, which plate or disk is centrally apertured for the reception of a screw-bolt or pin 28, which is flattened to prevent it turning in said disk when said pin or bolt is screwed into the socket 25 of the metallic rod 24. The pin or bolt 28 extends forwardly through the disk 27, and is provided in its forward end with a slot 29 for the reception and retention of one end ofthe igniting wire 30, which is convolute and of suitable material, and has its other end secured in the slot 31 of a metallic post 32 which is extended through the disk 27 so as to pro ject beyond each of its surfaces and so that its inner portion may be in position to be impinged against or contacted with by the contact spring 21 when pressure is applied to the push-button 20 of the cup 19.

Located within the igniter carrying cup 26 is a bushing or plate 33, of lavite or other suitable material, which is formed with a central opening for the reception of the pin or bolt 28 and also with an opening near its periphery, through which is extended the front portion of the post 32, which portion, as before stated, is slotted and holds one end of the igniting wire. The plate or bushing 33 is provided with an annular flange 34;, which extends outwardly within the cup 26, and said bushing has on its front surface a number of radially disposed ribs 35 to assist in supporting the wire 30. These ribs are of a depth less than the flange 3%, thus allowing the wire 30 to rest on their outer edges, yet to lie within the compartment formed by said flange. Resting on the flange 3 1 and externally of the wire 30 is a perforated disk, of mica or other suitable material 36, over which is laid a perforated disk 37, of very thin steel, the perforations of which register with those of the disk 36, of mica. The steel or metallic disk 37 is employed to protect the mica disk in the operation of lighting cigars, thus rendering it more durable.

From the foregoing and by reference to the drawing it will be seen and clearly understood that when the parts are assembled as above described and the conductors 18 are in electric communication with a generator, by pressing on the push button 20 the contact spring will be forced into contact with the post 32, thus completing the circuit so that the wire 30 will become heated to a high degree, when by applying the end of a cigar to the perforated plate 37, it may be ignited.

By providing the bushing 33 with the flange 34 an air space 38 is formed below the resistance wire where in the device shown and described in the application of Vheeler, such wire rested directly upon an asbestos sheet. By providing this air space I have found that the wire heats much more rapidly and to a higher temperature than was the case when no such space was provided. Such increase in time of heating and in temperature materially increases the efficiency of the device.

While I have shown the mica protecting disk 36 covered by the perforated steel disk, I have found that it is not absolutely essential to provide the latter and same may be omitted if desired.

Other modes of applying the principle of my invention may be employed, instead of the one explained and change may be made as regards the mechanism herein disclosed, provided the means covered by any one of the following claims be employed.

I, therefore, particularly point out and distinctly claim as my invention:

1.
