POCKET FLASH-LIGHT.

Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed December 26, 1914. Serial No. 879,002.

To all whom it may concern:

Be it known that I, ANKER S. LYHNE, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Pocket Flash-Lights, of which the following is a specification.

This invention relates to the class of pocket flash lights commonly known as pistol flash lights from the fact that the case is shaped to more or less closely resemble an automatic pistol, and the invention has for its objects to simplify and cheapen the construction by reducing the number of parts and to so construct and arrange the few parts required that it shall be practically impossible for any of the parts to become broken in ordinary use or to fail to work perfectly at all times, a wiping contact being provided in closing the circuit.

With these and other objects in view I have devised the improved pocket flash light of which the following description in connection with the accompanying drawing is a specification, reference characters being used to indicate the several parts.

Figure 1 is a view of my novel flash light in elevation, the case being open to expose the operative parts and the trigger being shown in the normal or open circuit position; Fig. 2 a similar view, the trigger having been moved to the closed circuit position, and Fig. 3 is a perspective view of the fixed electrical connection removed.

The case consists of two corresponding sheet metal parts, indicated respectively by 10 and 11, which are hinged together at the bottom of the handle portion.

12 denotes a dry cell battery which is socketed in the handle portion of the case and is provided with

spring terminals

13 and 14.

15 denotes an electric lamp which is detachably secured at the forward end of one of the parts of the case and is provided with the usual center contact 16.

In the present instance I have shown all of the operative parts as carried by part 10 of the case.

17 denotes a fixed electrical connection which is in constant engagement with the center contact of a lamp and the other end of which is bent backward upon itself, as

at 18, and is adapted to closely receive terminal 13 of the battery between the two plies of metal of the bend. This connection is secured by rivets 19 between plates of insulating material indicated by 20 and 21, and insulating plate 21 is secured to a bracket 22 by rivets 23, the bracket in turn being riveted to the case, so that there are no loose parts, I

In placinn the battery in the case, terminal 14 is pressed against the insulatin material 21 of the electrical connection 1 and is retained thereby in convenient position for engagement by the circuit closing means, thus avoiding the necessity of bending the terminal into various positions in an eflort to get proper contact.

24 denotes the trigger which is protected by a guard 25 and is normally retained in the inoperative or open circuit position by a spring 26.

27 denotes a spring contact which is carried by the trigger and is adapted to engage terminal 14. This contact is preferably curved substantially as shown in the drawing, so as to cause it to engage the terminal with a'wiping engagement when moved to the circuit closing position, as in Fig. 2.

The operation will be obvious from the drawing.

Electrical connection 17 is always in engagement with one of the battery terminals and with the center contact of the lamp, but is insulated from the case. The spring normally retains the trigger and spring contact in the open circuit position as in Fig. 1. To close the circuit and flash the lamp the operator pulls the trigger and places the spring contact in engagement with the other battery terminal, as shown in Fig. 2. This completes the circuit from the battery through connection 17 to the lamp and from the lamp through the case, the trigger and the spring contact back to the lamp. The instant pressure upon the trigger is relieved the circuit is opened again by the action of the spring.

Having thus described my invention I claim:

A flashlight comprising a case adapted to carry an electric lamp and a dry cell battery having spring terminals, a trigger pivoted to said case, a spring contact carried by the trigger and adapted to engage a battery terbattery terminal which coacts with the trigminal, a bracket, an electric connection havger contact in operative position. 10 ing means for engaging the other battery In testimony whereof I aflix my signature terminal and an end for engagement with an in presence of two witnesses.

electric lamp and insulating plates between ANKER S. LYHNE. which said connection is secured, said insu- Witnesses:

lating plates being carried by the bracket HERMAN K. BEACH,

and one of said plates acting to retain the COLEMAN PHILLIPS.
