F. B. FARNSWORTH LIGHTER FOR CIGARS,' FIPES, AND THE LIKE Filed Sept. 27. 1923 -Patented Nov. 3, 1925.

FRANCIS B. FARNSWOBTH, OF GRANBY, QUEBEC, CANADA.

LIGHTER FOR CIGARiS, -PIIIES, AND THE LIKE.

Application led September 27, 1923. Serial No. 665,214.

To all 10710111. t may concer/1.' I

Be it known that I, FnANois B. FARNS- WORTH, of the cit-y of Granby, Province of Quebec, Dominion of Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in Lighters for Cigars, Pipes, and the like; and I do hereby declare that the following is a full` clear, and exact description thereof.

My invention -relates to electrical cigar, cigarette and pipe lighters of the type in which a high resistance clement is employed as the igniter proper.

The object of the invention is to provide a lighter of this type employing a simplified ignition element which may be screwed into any electric socket and which may be easily replaced at a moments notice at a minimum cost.

A further object is to provide a simple and etiicient desk lighter which includes said ignition element as a component part and which may be operated by a push-button switch.

To this end the invention consists of the construction and arrangement of the separate and combined parts hereinafter described, illustrated and claimed.

For full comprehension, however, of my invention reference must be had to the accompanying drawings in which similar reference characters indicate the same parts, and wherein:

Figuie 1 is an elevation partly in section of a desk lighter constructed according to my invention;

Figure 2 is a vertical sectional view taken on line 2 2 Figure 1;

Figure 3 is a top view of the ignition element;

Figure 4 is a sectional view taken on line 4 4 Figure 3; and

Figure 5 is a sectional view taken on line 5-5 Figure 3.

The desk lighter illustrated in Figure l constitutes the preferred embodiment of my invention but it is to be distinctly understood that its shape and general pro ortions may be modified without departing rom the spirit of the invention.

It consists of a hollow pedestal or base 2 adapted to contain a transformer or a storage battery, the former being illustrated as at 3, a vertical standard 4 of tubular cross- 'section having its lower end screwed into the 'top of the pe estal and llingedly supporting a socket 5 at its upper end, and an'ignition element G screwed into the socket. The hinged connection between the socket and the standard consists of bifurcated members? and 8 having their adjacent arms hinged together by pins 9 with cupped heads l() tov taclnnent cord and plug 1G for connection with any adjacent lighting circuit while the secondary circuit includes the socket 5 and the ignition element 6. It is immaterial, l1OWeVer,Where the push button switch is located. If found more desirable it may be incorporated in the secondary circuit in stead of the primary in which case, when a transformer is employed, the primary will be closed and the secondary normally open.

The ignition element consists of a high resistance conductor 17 mounted between two protecting lugs 18 and 19 on the outer end of a plug 20. The latter comprises a metal shell 21 upon the opposite ends of which are clampedia porcelain or iirette disc 2 and a bre washer 22 by a centrally disposed bolt 23 and nuts 24 and\25, the disc having a central depression 26 and opening 27 to accommodate the bolt head and shank, the inner end of which is adapted to engage the central contact 28 of the socket 5. The resistance 17 may be anchored upon the outside face'of the disc in any desired manner..

In the present embodiment the coiled element is' bent to V form and its free ends 29 and 30 respectively passed through openings 31 and 32 in the disc, the end 29 being extended outwardly and contacting with the shell and the other 30 being clampedy upon the disc by nut 24 and thus establishing contact with the bolt 23. The crotch of the V is anchored in place by a wire loop 33 which is passed through openings 34 in the disc.

In order to protect the ignition element from injury when in use and to eliminate draughts and provide a centering guide for pipes and the like the outer end of the element is encircled by a cup annulus 35. This annulus is provided with a threaded cylindrical extension which is screwed into the socket 5 andinto which the plug may be inserted, the inner end of the extension having an inwardly projecting flange 36 to hold the protector and plug against displacement relatively, to each other.

Operation.

In the operation of this lighter the cigar, cigarette, pipe or the like is held in close proximity to the ignition element While pressure is applied to the push-button'with the result that the current passing through the element instantaneously raises the temperature of the latter to a degree at which the tobacco is readily ignited.

lVhat I claim is as follows 1.. In an electric lighter, a socket, an igniting element mounted in said socket, and a cupped annulus encircling said element.

2. In'an electric lighter, an igniting elenient consisting of a plug having an end of refractory material, spaced lugs projecting outwardly from said end, and a resistance mounted upon said end between the lugs.

3. In an electric lighter, an igniting element consisting of a plug having an end of refractory material, spaced lugs projecting outwardly from said end, a resistance mounted upon said end between the lugs,

and a cupped annulus encircling said end.

4. An igniting element consisting of a screw threaded 4metallic cylinder, a refractory disc mounted upon one end of the cylinder, a fibre disc mounted upon the opposite end ofthe cylinder, means clamping the discs in place, consisting of a centrally disposed bolt and nuts screwed upon the bolt and engaging the respective discs, and a resistance mounted upon the outside face of the refractory disc and having its ends con tacting with the cylinder and bolt respectively.

5. A n igniting element consisting of a screw threaded metallic cylinder, a refractory disc mounted upon one end of the cylnder, a fibre disc mounted upon the opposite end of the cylinder, means clamping the discs in place, consisting of a centrally disposed bolt and nuts screwed upon the bolt and engaging the respective discs, and a resistance mounted upon the outside'face of the refractory disc and having its ends c0- acting with thc cylinder and bolt respectively; lugs projecting from the refractory disc on opposite sides of the resistance, and a cupped annulus encircling the refractory disc and extending outwardly therefrom.

In testimony whereof I have signed my name to this specification.

FRANCIS B. FARNSWORTH.
