portable electric the type ener- This invention relates to lamps, especially those of gized by a battery contained within a flat casing. The principal object of the invention taining the battery ce s in position.
,In lamps of this type separate cells may be used, or a unitary battery may be prepared by packaging aplurality of cellsand aiiixing suitable contact members. mentioned procedure is advantageous in that one or more of the cells may be replaced when necessar without disturbing the others. Also, ac aging, adds materially to the cost of t e battery. The present invention provides simple and reliable means for obtaining these and other advantages of the unit cell battery.
In general, the invention comprises a casing provided with resilient means for supporting a plurality of cells in laterally alined relation, and means' for series connecting the cells in a circuit including the lamp filament.
A preferred embodiment of the invention is illustrated lin the accompanying drawings in whith Fig. 1 is a front elevation of the lamp, the cover being in open position, and Fig. 2 is a vertical central sectiony on line II-II of Fig. 1.
ferring tothe drawings, 1 indicates a cup-shaped bottom section of a flat .metal casing comprising a complementary cupshaped cover section 2 hinged at .3. The embodiment of the invention which has been selected for illustration is intended for use as a. pocket flashlight, and the casing is there-` fore rounded at its margin, so that itniay fit conveniently into the pocket of the user. The dimensions and contour of the casino' are adapted to the ordinary cylindrical flashlight cells. iy desired configuration of the casing may be chosen, however, with a view to the intended use of the lamp or the shape of the battery cells. 'A projection 4 is stamped in the side of casing 1 andvsnaps into depressible locking catch 5 when the cover 2 is closed.
A bulb holder 6 having a threaded stem 7 is mounted in a circular orifice in a bracket 8, which is attached to the casing in any suita le manner. The holderis partly enclosed in a semicircular recess 9, and a correspondi ing indentation 10 in the end wall of cover 2 receivesy the projecting portion of the holder.
1s to provide improved means for rey `rated The first The exterior rim of holder 6 islpreferably substantially. flush with the casing. Alamp bulb 11 is screwed into the threaded stem 7 and its outer terminal is i electrical contact with the stem. The inner lamp terminal 12 projects below the holder 6. L This terminal makes contact with a conductive tubular rivet 13 carried'by a dished perfotongue 14, preferably of resilient metal and forming an integral part of y bracket 8. f
Tongue 14 is electrically connected to the casing. o insulate the rivet 13 from the tongue, the perforation in the latter is made of such diameter as to leave an the rivet. This clearance and insulation are maintained by a liber ring 15v set in the dished upper surface of the tongue 14 "and a second similar ring 16 placed be. neath it. The rings are clamped in position upon the tongue b expanding the ends of the rivet upon them, as shown in Fi 2.
The means for removabl supporting the' cells comprises upper an lower resilient arms 17, 17 and 18, 18', arranged in pairs in vertical alinement. The upper arms 17 18, may be conveniently formed integrally witllli bracket 8. Arms 17', tia
secured to the casing, by soldering or the like, with its concavity adjacent the casing bottom.` In this manner'a conduit is formed., for insuand 21, which connect the cells in series, as subsequently described.
The resilient arms 17, 17-, 18, 18, like the tongue 14, are provided with a central perforation and a concave upper surface. Tubular conductive rivets 22, 23, 24, 25, are passed through the perforations of arms respectively. Fiber rings 15 are clamped in ly'described, to insulate the rivets from theV arms. Wire 20 connects rivets 23 and'24, and wire 21 connects rivets 25 and 13.
A metal casing has been described, but
it will be understood that features of the,
invention are applicable as well to nonconductive casings. The number of cells may also be varied as desired.r Various other changes may be made in form and arrangement of parts, within the scope of the appended claims.
