LAMP.

Listeria.

To all 10710221 it may concern Be it known that I, ARCHIE B. Guns, a subject of theliing of Great Britain, residing at Peterboroughj Province of Ontario, Canada, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

This invention relates to lamps and has special reference to portable electric lamps designed .to be carried in the hand and lighted 0r extinguished by a pressure of the thumb.

The primary object of my invention. is to provide a lamp of simple and inexpensive construction which may be fitted to an ordinary dry cell.

A secondary object of the invention is to provide a novel means for supporting the lamp bulb and for controlling the circuit.

Other incidental objects will appear as the description of the invention proceeds.

The invention is fully illustrated in the accompanying drawing and consists in cer' tainnovel features which will be particularly pointed out in the claims following the detailed description.

In the drawings. Figure 1 is a side elevation of a lamp embodying my improvements with a portion ofthereflcctor broken away and in section. Fig. is atransverse section on the line 2 ofI ig. 1. Fig. 3 is an enlarged detail longitudinal section.

I In the drawings. the reference numeral 1 indicates an ordinary dry cell battery equipped with a binding post or nutintimately connected with the zinc element of thef'cell so as to form an electric terminal. Thecarbon of the cell is projected beyond the'end of the battery. as shown at 3, and to provide a perfect contact with the carbon, I mount in the end of the same a bindingposiid which carries a terminal in the form of an L-shaped metallic plate having one arm securely clamped on the binding post and the other arm fitting over and lying against the extremity of the carbon projection 3. I also provide a holder con sisting of a bar or metallic strap 6 adapted to extend along the battery cell 1 and having one extremity turned down. as at .7, to fit against the bottom or rear end of the cell. A handle or loop 8 of similar material is rigidly secured'to this bar 6 and projects laterally therefrom so that the device may, be coni'eniently carried by the user. Sercured to the bar 6, preferably at the points Specification of Letters Patent. Patented Apr. 27, 1915.. Application filed November 10. 1914.

Serial No. 871.324.

of junction of said bar with the ends of the handle 8, are holding members 9 which are preferably in the form of resilient jaws adapted to lit closely around the cell, as shown most clearly in Fig. 2, the ends of said jaws being projected somewhat from the cell and curved outwardly so as to facilitate the attachment of the jaws to the cell. lVhen the device is made of heavy material, the resiliency of these jaws or clamping members will be suilicient to retain the cell in the holder but if lighter material is employed a clamping bolt, indicated in dotted lines at 10. may be inserted through the outturned extremities of the jaws so as to. securely clamp the jaws around the cell as will be readily understood. The forward or. upper end of the bar 6 isextended beyond the adjacent end of the cell and is deflected or bent slightly away from the cell. as shown at 11. so as to clear the;binding postor terminal 2 and beyond said deflected or curved portion 11 the said extended end of" the bar is carried downwardly and curved so as to form a seat 12 for the reflector which passes lhe reflector 131s.

close to the terminal 5. sweated or otherwise rigidlv secured upon and to the seat 19 and the reflector and said seat are pro ided with registering openings in which is fitted a metallic shell l-l which receives the socket 15 of an electric. bulb 16.

A lens 17- is carried by the outer end or edge of the reflector 13 so as to protect the bulb 16 and also divert the rays emanating from the lamp and projected fronrthe reflector,

as will be readily understood. ,The shell'l-L should be somewhat shorter than the socket 15 so that when the lamp is turned home in the shell. as shown most clearly in Fig. .3,

the inner terminal of the socket will bear directly against the terminal 5 and form a part of the electric circuit. The metallic out-er portion of the lamp so'clcetwill form electrical contact with the shell ll in the usual manner and the course of the current will be through the saidshell and the bar 12 to the battery.

In order to provide a connection between the seat 12 and the battery and to permit the circuit to be broken or closed at will. I secure upon the handle 8 a leaf spring 18 which has its free end bent downwardly beyond the handle and extended through a slot or opening in the bent or curved portion 11 of the main member of the holder. As shown in Fig. l, the extremity of this leaf spring will lie close to the binding post 2 so that a slight pressure upon the bend of the spring will force its extremity against the said post whereupon the circuit will be completed and the lamp will be lighted. 'To

permit a more; perfect contact between the said spring and the binding post. or terminal,

I form a notch 19 in the end of the springwhich is adapted to engage the grooved portion of the nut or to fit around the screw or bolt of said terminal. have the lamp permanently lighted, the nut may be loosened sufliciently to permit the end of the spring to fit around the bolt or screw and the nut then turned home-so as to secure the spring permanently in engage mentwith the post.

It will be readily understood from the foregoing description taken in connection with the accompanying drawing that I have provided an exceedingly simple structure whereby any ordinary dry cell may be utilized to supply current to a small electrie tuted very easily and in a very short period The outturned extremities of the of time. jaws 9 constitute feet for supporting the device when it is not in use. The lens may be of any preferred style and the particular form of the reflector is immaterial.

Having thus described the invention, what is claimed as new is 1. A device for the purpose set ,forth comprising a bar adapted to extend along a cell and having one end projecting be-- yond and-across the cell to form a lamp support in proximity to one terminal of the cell, clamping jaws projecting laterally from said bar to engage around'the cell, and

a circuit closer co-acting-with the lamp sup port to make'or-break a circuit through the other terminal of the cell.

2. A device for thepurpose set forth comprising a bar having one end bent laterally to extend under an electric cell and its'other If it be desired tot end projected beyond saidcell and'extended across the same to form a lamp support, jaws secured to said bar and. adapted to engage and hold the cell, a terminal secured upon one member of the cell adjacent the lamp support, and a circuit closing member coacting with the lamp support to-make-or break a circuit through the otherelem'entof the cell. i 4

3. A device for the purpose set forth cont. prising a bar adapted to'extend-along a cell and having one end projected 'beyondand across the cell to form a lamp support, clamping jaws secured to said bar and adapted to engage around thecell, ahandle secured to the said bar, and a circuit closing or breaking member secured upon the said handle and adapted to engage a terminal. of the cell.

. 4. A device for the purpose set forth comprising a bar adapted to extend along an electric cell and having one end' projected beyond and across the cell, a shellrigid with the said bar'and adapted to receive an elec-. tric lamp, an electric terminal secured upon one element of the cell immediately adjacent .said shell and adapted to be engaged by aterminal oi said lamp, and a circuit making or breaking plate adapted to form an electrical connection with the other element of the, cell and 'coact with-the said bar to complete a circuit through the lamp.

5. A device for the purpose set forth comprising a bar adapted to extend along an electric cell and having one end extended be yond and across the cell and provided with an opening adjacent a projecting element oiv the cell, a shell secured in said openingand adapted to receive an electric lamp-and form an electrical'connection therewith, the said shell being so dispose-d that when the lamp n is securedtherein it'will form an electrical connection with the adj acent element of the cell, a binding post on the other element of the cell, and a leaf spring extended through the said bar and adapted to engage said binding post. y

In testimony whereof I afiix my signature in presence of witnesses. l
