.To all 'whom z't may concern:

` Be it known that I, CHARLES J. SAGE- BREoH'r, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have in-. vented certain new and useful Improvements in Portable Electric Flash-Lights, of which the following is a specification.

The invention pertains more particularly to portable electric lights of a character adapted, owing to size and compact'ness, of being carried in the pocket of the user.

considerable diiiiculty has heretofore-existed in some classes of pocket fiash lights in preventing the moving around'of the battery within the metal casing and the accidental making of the circuit through' the lamp, battery and casing due to such shifting of the battery, the shifting of the battery frequently carrying its terminal into contact with the circuit closer. The result of this has been that the batteries have been unnecessarily consumed and sometimes have been pronounced worthless, whereas in fact they have been consumed while the lamp was in the pocket of the user and without his knowledge.

The object of the present invention is to provide a compact -fiash light adapted to receive abattery of ordinary construction and to avoid the contingency of the circuit being made by an accidental shifting of the battery in the case.

The invention will be' fully understood from the detailed 'description hereinafter presented, reference being had to the accomp'anying drawings, in which:

Figure' 1 is a side elevation of a pocket flash light or electric lamp embodying my invention; Fig. 2 `'is an elevation of the same with the two halves of the inclosing casing shown in their open position; Fig. 3 is a transverse section, on an enlarged scale, through the same on the dotted line 3-3 of Fig. 1; Fig. 4 is a vertical section, also on an enlarged scale, through the upper portion of the same on the dotted line 4-4 of Fig. 1; Fig. 5 is an enlarged view of a portion of one-half section of the same, corresponding with the left hand portion of Fig.

. 2, showing the circuit closer as having been moved to its circuit closing position from its normal position illustrated in Fig: 2, and Fig. 6 is a detached Sectional view about on a line 6--6 of Fig. l, showing the latch for latching the two half sections of the outer casing in closed position.

In the drawings 10 designates an exterior metal casing of rectangular general outline but having rounded edge portions, said casingl being composed of two shallow half sections ll, 12 connected together at one edge by the hinge 13 and at their opposite meeting edges being equipped with lat-oh members comprising a leaf spring 14: riveted at its upper end, as at 15, to the half secton ll and provided. at with a. latch member 16 and thumb-piece 17, said thumb-piece being extended through a slot 18 formed in the section ll and said latch'meniber 16 being simply an extension of the spring 14 and containing an opening to sna-p over a stud 19 formed by indenting the metal of the section 12 inwardly for the purpose of interlocking with said latchmember 16 when the two half sections of the casing are closed together, see Fig. 6. There its lower portion is no special novelty in the means for lock-v of the half section 12 of the casing 10 is secured a reflector 19a and the other half section of the casing at its upper middle portion is rocessed, as at 20, to fit around said reflector. Wlithin the reflector 19a is secured the electric lamp bulb 21 whose threaded socket engages said reflector and also enters a bracket plate 22 which is somewhat of right-angular formation and fastened directly to the inner wall of the half section 12 by solder or otherwise, the exterior casing and lamp being by means of said bracket 22 placed in electrical connection. Upon the vertical member of the bracket 22 is secured a bar 23 of non-conducting material, and upon the outer end of this bar .is secured by eyelets or rivets 24, two substantially corresponding plates 25, 26 of right-angular formation having end of the socket for the lamp 21, and its vertical short terminal 30 extended upwardly into the aw 27 formed by the plates 25, 26, as will be understood on reference to Figs. 2, 3 and 5. The battery 28 is seated upon a right-angular fiange 31 which is soldered to the half section 12. Fig. 2 shows the electric lamp with the casing thereof opened outwardly, but otherwise illustrates the parts of the lamp in their normal position with thecircu't closer spring 32 in its -upper position free of the jaw 27 and the plates by which said jaw is formed. The circuit closer'spring 32 lies within'the outer vertical portion of the half section 12, and

it isadapted to-have a vertical movement under the influence of manual pressure ap- .plied to a buttonhead 33 connected therewith and having-its shank within a. vertical slot 34 in the half section 12. The lower end of the spring 32 is slotted, as at'35f(Fig.

' 5), and held by a loose rivet 36 whose' sha'nk ,v form approximately of the letter V, as at 37. When the upper bent end of the spring 32 is in its upper position shown in Fig. 2

there will be no circuit through the battery and lamp, the circuit being broken at the space between the upper bent end of said vspring 32 and the facing portion of the plate 25 and battery terminal 30. When it is desired to complete the circuit through the battery and lamp the user will, by pressure applied to the push-button 33, cause the spring 32 to slide' downwardly, and this will result in the spring at 'its upper'bent end engaging the plate 25 'and completing the circuit through the battery and lamp.

In order to assure an adequate contact of the upper bent end of the spring 32 with the plate 25 when said spring is pushed downwardlyand to avoid said bent end from normally standing too close to said plate 25 and to the battery terminal 30, I form a stud 38 on the inner surface of the half, section 12 behind the spring 32 and forma recess or loop 39 in said spring so that when the spring is in its upper position said recess i or loop may pass upon and engage the stud 38 and by its spring tension lie close against the surface of the section 12 and also so that when the spring 32 is slid downwardly, the stud 38 will act to wedge the 'upper bent end of the spring inwardly toward and against the plate 25, this latter action being illustrated in Fig. 5. The plates 25, 26 hold the batte' terminal 30 and so position said ternijinal at any slight shifting of the battery within the casing will not result in said terminal being moved .into engagement with the circuit closer spring 32. The plates 25, 26 may be bent to some extent to adapt them to the small variations that exist in the position of the terminal 30 with respect to'the battery.

It is believed the invention will be fully' understood from the foregoing description, and that further explanation is not required. It may be mentioned however that the platev26 may be noncondu-cting or even, with some disadvantage, omitted, since .the plate 25 extends at right angles toand transversely of the terminal 30 and above the battery 28 and is, at the proper time,-

engaged by the bent end of the spring circuit closer 32 to complete the .circuit through said battery terminal 30. The engagement of the plate 25 with the terminal 30 and the fact that said plate extends transversely of and above the battery perin place.

What I claim as my invention and desir to secure by Letters Patent,'is:

1. A portable electric light comprising a casing in two hinged together substantially corresponding longitudinal sections having latching means at their free edges, a battery in one of said sections having the usual two terminals, an electric lamp socketed in the end of the same section and in electrical env mits said plate to aid in holding the battery gagement with one of said terminals, a jaw.

secured within and insulated from said section and receiving between its members the other of said terminals, and a circuit closer carried by said section and having an upper end to engage the adjacent conducting member of said jaw when in one lposition and stand clear thereof when in its other position.

2. A portable .electric light comprising a metal casing in two hinged together substantially corresponding sections having latching means at their free edges, a battery :sol

in one of said sections having the usual two terminals, aI bracket secured within and near the upperend of the same section, a reflector held at the end of said section, an

electriclamp held by said bracket `with its bulb within said refie'ctor and its contact in engagement with one of said terminals, a ljaw insulated from and secured. to said bracket and receiving between itsmembers the other of said terminals, and-a slidable circuit closer carried by said section and having an inwardly extended upper-end to engage the adjacent conducting member of said jaw when one position and stand clear thereof when in its other position.

3. A portable electric lightcomprising-a casing in two hinged together substantially corresponding longitudinal sections having latching means at their free edges, a battery1 in one of said sections having the usual two terminals, an. electric'lamp socketed in the. end of the same section and in electrical encuit closer carried by said section and have' ing an inwardl') extended upper end to engage the adjacent' conducting member of said jaw when in one ,position and stand clear thereof when in its other position, said circuit closer being of spring metal having an exposed head connected therewith' for its manual operation and also a recess in its outer face, and said section having an inwardly projecting studto enter said `recess when the closer is ili-'its inoperative position and serve as `a .wedge'to force the upper end'of said'closer linto engagement with said conducting jaw member when the closer isomoved to its operative position.
