HANDLAMP SWITCH.

Application filed February 21, 1921.

To all whom it may concern.

Be it known that I, ARTHUR L. STAPLES, a citizen of the United States, residing at New Haven, in the county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Handlamp Switches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to portable electric lamps comprising a casing, a battery and an incandescent lamp mounted therein, and a contact device on the casing by which th flow of current from the battery through the lamp may be controlled at will.

In a portable lamp of this character, it is desirable that the user shall be able to flash the lamp, that is, light it for short periods of time, as in signaling, or for such length of time as it is convenient for the operator to hold his thumb on the contact device. It is also desirable that means be provided for closing the switch to light the lamp for a longer period of time and without the need for continuous thumb pressure on the contact mechanism.

It is an object of the present invention to provide a hand lamp with a contact mechanism so arranged that the lamp can be flashed or can be permanently lighted, as desired, but with the additional feature that the contact mechanism cannot be locked in closed-circuit position through accidental pressure on th contact device. This permits the hand lamp to be carried about with tools or in the ocket of an auto-mobile door without the anger that when the lamp is needed its battery will be found exhausted because, through accident, the switch has been closed and th lamp has been lighted without the knowledge of the user.

Other objects and advantages will become apparent from the following description, which is to be taken in conjunction with the accompanying drawings, wherein Fig. 1 is a view in elevation of a handlamp constructed in accordance with my invention.

In carrying out my invention, as herein shown, I employ a sheet metal escutcheon plate 20 rigidly mounted by means of rivets 21 over an opening 22 in the side of an insulating casing 23. An aperture 24 is formed centrally in the escutcheon and is filled flush by a correspondingly shaped push-button 25 struck up from a sheet metal spring contact 26- positioned against the under surface of the escutcheon 20 and rigidly attached at its rear end thereto by a rivet 27. Forward of the button 25, the spring contact 26 is bent inward and forward to lie fiat against the inner surface of the casing 28 and extends nearly to the forward end thereof. In the preferred form of myinvention shown in Fig. 1 the spring contact 26 is formed with an inward how 28 which prevents the battery 29, positioned within the casing, from interfering with the contact device and also increases the length of the spring 26 between the rivet 27 and the push-button 25. In the alternative form shown in Figs. 6,'through 10, there is no battery positioning means and in the form shown in Figs. l114 there is a battery positioning. spring 30 separate from the springcontact 26, held in. place by the rivet 27.

g In the preferred form shown in Figs. 1 and 7, the escutcheon lies flat, but in the alternative form shown in Fig. 12 it is raised centrally to simulate the housings employed in hand-lamp contact-devices of the prior art.

The escutcheon plate 20 is slotted asshown at: 3: in the preferredferinin; Figs. Land 11 at each side of the central opening 24;, or, as, shown at. 32 in. an alternative form. F ig. 9v forwardly of the. opening. 24: for the reception of a longitudinally slidable. lock.

per edge a knurled operating. portion. 36.

while the central part of the. upper edge is depressed to lie below the surface. of-the p'ush button 26 which the slide traverses. In eachend of the lockare longitudinalhorizontal slots 37 receiving the. metal. ofthe escutcheon 20 at the outer ends of thefslots 31 whereby the lock is'held slidably in place.

.In the alternative form, shown inFigs. 8.

and 9, the lock has hollow knurled thumbpiece 38 the side walls of which extend down through the twin slots 32 of. the

escutcheon 20 and areformed with lugs 39 which are bent inwardly embracing theporti'on of theescutcheon between the slots 32 and also the'narrowed central part of the body 40 of the sheet metal locking lug 34.. By this construction the slide comprisin' the thumb-piece 38 and the locl 34 is helc together and in place.

In the forward end. of the tube is positioned a reflector ll of well known form having an insulating strip 42 folded about its outer edge and an electric bulb' l3 mounted in its center, the outer terminal of the.

bulb beingin contact with the reflector and the inner termlnal in contact with the pos1- tive electrode i l of the battery '29. On the exterior surface of the tube 23. at. its. forward end 18 rigidly mounted the customary threaded metal ring 45 upon which is.

screwed the threaded metal lens mount 46 in which the lens t? is held between the spun in collars' l8 and 49. The reflector is held in place by having its outer edge gripped between the end of the tube 23 and V the lens supportingcollar 48 andis insulated;

from both by the strip 42.

On the rear end of the tube is thecustomary construction 1-521 threaded metal ring 50 rigidly mounted on the tube 23, a sheet metal threaded cap 51 screwed thereon and the spiral metal spring 52 interposed between the naked base of the nega-tive pole-of the battery 29 and the cap 51.

A metal conductor strip 53 is hooked over the rear endof. the. tube 23 under the ring 50' and in electrical contact therewith and extends forward along the inner surface of thetube and is held inpl ace by one of the rivets 21, which; also connects. it electrically to the escutcheon plate 20. In thepreferred form, shown in Fig. 2, the strip 53 terminates just forwardof the rivet 21. In the alternative. (lOllSblU-QtlOIl, shown in Figs. 7 and, 12, the strip. 53 extends nearly to the front: endof the tube and is further held in place; by a rivet. 54 which is one of the fast.- enings' of the ring &5; In this construction all of the exposed metal parts of the case are; electrically connected to the negative pole; of thebattery and therefore, sincethey are-all, .0f.onepolarity, thebattery cannot he accidentally short-circuited byegrternal con tact of the case withiconductive bodies. The; preferred form, shown in Fig. 2 issimilar in this respect. except forthe fact that the front ringer). and the. lens support 46 are normallyelectrically dead. I

In the; preferred form, shown in Fig. 2, the construction is now completely described.

'Hfowe-ver, under some circumstances it is thoughtbetterto give further support against lateral distortion of the contact spring-,26. In the. alternative form, shown in Figs. 8 and 12, the contact spring 26.is formed near itsforwardendwith a guide slot 55 which receives a vertical guide. lug 56 dependent from an integral rivet 57 setin the tube 23 under the ring l5.

When, in use, the push-button 25 is depressed, the spring 26 yields and the outer end. thereof contacts with the reflector 41 closing the electrical circuit. through the lamp, which lights and remains lit as long as. thepush-button is depressed. the Spring contact 26 has moved sufiiciently to. bring the;ed'ges of the slot 35. below the lug; 34.; 9; forward push on the knurled parts 36 or 38 while the push-button is held 7 down willeausethelug 34 to move forward overt-he spring26 in front of the slot-.35 and to holdthe same depressed until the thumb pie'ce36 or. 38 ispushed rearwardly again, when the lug 35L will snap. into. the slot 35 and the front end of the contact springwill again breakrontactwith the reflector.
