Definitions
- the present invention relates to portable battery lamps and more particularly to lamps adapted for carrying in the hand'or in the pocket..
- FIG. 1 is a sectional elevation through the complete lamp; and Fig. 2 is an exploded viewv showing the lens tube and the spring socket detached from the corresponding ends of the lamp casing
- the device comprises a casing 1 of insulating material such as fiber or the like within which may be introduced a plurality of batterv cells 2 and 3 inclosed in a paste board jacket 4.
- Cell 3 has its naked zinc container resting on the central electrode 5 of cell 2, and the central electrode 6 of cell 3 contacts with the inner terminal of the incandescent lamp 7.
- the outer terminal or sleeve of the lamp socket isthreaded into the tubular extension 8 of the reflector 9. which is in the form of a cup with a.
- the relictor is electrically connected with a metal strip 11 by means of solder applied at 12 through a narrow notch cut in the end of the fiber tube 1, and this conductor 11 extends back approximately to the middle of the fiber casing and there is bent through and folded down to form a lug 13 at which electrical connection with the lamp Vmay be established.
- a spring contact device vnot herein claimed, but claimed per Se in Maisel Patent No. 1,082,887, issued December 30, 1913, this device comprising a housing 14 pressed up from sheet metal and having side flanges through which the rivets 15 may be passed for securing the housing to the fiber 4casing 1.
- One of these rivets may serve to establish electrical connection between this housing and a.
- ⁇ metal strip 16 extending longitudinally of the 4casing and terminating in a lug 17 gripped between the end of lcasing 1 and a flange on the edge of a metal ring 18 reinforcing the end of the casing'and held in position by rivets 19 which project outward to form retaining lugs.
- socket 2() contains a helically-coiled spring 22 which normally bears against the zinc electrode of cell 2 and establisheselectrical connection therewith.
- a pin and thumb piece 24 project through a slot in housing 14 and aii'ord a means for sliding the contact when the thumb piece is pushed inward and forward by the operator.
- a lock is provided to prevent accident-al sliding of vthe contact member and consist of an outturned lug 25 on the contact member projecting through a slot in the-housing member as shown in the drawings; so that sliding movement of the contacter is impossible unless the thumb piece is pushed inward at the same time it is ⁇ being pushed forward.
- the lamp would light up Awith its thumb contacter open, and thus might completely wear out its batteries to no useful purpose.
- I claim Y 1 In a battery hand lamp, the combination of an insulating'cas'ing, batteriesand a lamp mounted therein, a focusing lens for said lamp and a Itubular support for said lens and tok which it is permanently attached, said support being mounted directly on the fiber tube and insulated thereby and adapted to slide thereon in changing the focus of the light fromy the lamp.
- a battery hand lamp an insulating casing, batteries and a lamp therein, a reflector and a lens for said lamp, and a tubular support for said lens slidingly mounte on said casing to change the focus of th light, and insulated from said reflector t avoid accidental lighting of the lamp.
- a tubular hand lamp the combina- A .tion of an insulating casing, a battery there- 1n comprlsing a plurality of cells arranged 'end to end, a lamp at one'end .of said casmg, a metal closure for theother end of said casing, said closure being removable to facilitate removalof said battery through said last-named end and carrying a spring for establishing connection with one end of said battery, a reflector for said lamp connected through said lamp with the other end of said battery, stationary conductors electrically connected to and leading from said reflector and said metal closure, respectively, and terminating near the center of said casing, where their adjacent ends are spaced apart to form a switchl gap, a lens for said lamp and a metal lens support enveloping said reflector and the front end of its stationaryconductor and insulated from all parts of the electrical circuit, and means for closing said'switch gap when the lamp is to be lighted and for-housing said gap to prevent accidental bridging thereof by an extra
- a tubular battery lamp comprising an insulating casing, batteriestherein, a contact device carried by said casing, a metal.
