FLASH LAMP.
Application led March '7, 1925. Serial No. 13,670.
This invention relates to improvements in a i'lash lamp of the type generally knownas electric pocket lamps or flash lights.
The object of the invention is to construct a lamp which is substantial and durable, and which may be conveniently operated to make or break the electric circuit controlling' the lighting of the lamp bulb; a further object ot' the invention is to provide a sectional casing having a lockingdevice thereon by loe locked either in a position to light the lamp bulb or to prevent accidental lighting ot the lamp bulb when carrying the casing in the pocket. A still further object ot the invention is to provide a novel form of contact pin yieldably mounted within the casing` and adapted to make a perfect contact with battery cells which may vary slightly in length, thus permitting the sections of the casing to be locked in a given position for closing the electric circuit and thus insuring the contact pin always being in engagement with the cellgthese together with various other novel features ot construction and arrangement of the parts, which will be more fully herein after described and claimed, constitute my invention.
Referring to the accompanying drawing, Fig. 1 is a side elevation of the lamp embodying the invention; Fig. 2 is a view simi lar to F ig. 1, partly in section showing the parts in a position to complete the electric circuit; F ig. 3 is a side elevation, partly in sect-ion of the casing body section containing the lamp bulb and battery cell; Fig. 4 is a longitudinal sectional view, partly in elevation, showing the cap section of the casing detached; and Fig. 5 is an end View o1 Fig. 1.
In the drawing, in which like reference characters refer to like parts, the casing shown is of tubular formation and consists of two sections, 6 and 7; the section 6 forms a body portion and the section 7 forms a cap which is slidably mounted upon the body portion.
The section 6 oi the casing is adapted to receive an incandescent lamp bulb 9, with one pole in electrical Contact with the casing in the usual manner. A battery cell 10 is looselymounted within the casing section 6 with one end pole in contact with the center contact of the lamp 9. The casing section 6 cell 10 when the sections 6 is also provided with a stud, or pin 12, adapted for engaging the cap 7, provided with a locking device hereinafter described.
The casing section forming the cap 7 is provided with an end plug 111 adapted to be soldered, or otherwise secured in the cap 7. A sleeve 15 is formed upon the plug 14;, in which sleeve is mounted a contact pin 16 adapted to project through a screw plug 17 provided with a central aperture in which the pin 16 is slidably mounted. Said plug 17 is screwed into the inner end ot the sleeve 15, and forms a stop against which a collar 16 on the pin 16 is forced by the action of a spring 2O located within the sleeve 15. The 'plug 7 thus limits the movement of the pin 16 in relation to the sleeve 15 by the action oi the spring 20. The contact pin 16 is adapted to malte contact with the end of the and 7 of the casing are Vforced together into the position shown in Fig. 2, and complete the electric circuit including the casing sections 5 and 6, the. cell 16, and the lamp 9. When the parts are in the position to thus close the circuit, the spring 2O is compressed, thus forming a tension between the cell 10 and the end lot the contact pin 16, and thus insuring a good contact and also compensating for battery cells Vwhich i length. Y
The two sections 6 and 7 of the casing are automatically moved, by a spring 25, into the position shown in Fig. 1, with the contact pin 16 separated from the cell 10 and the circuit broken. Said spring 25 is secured at one end thereof to the end plug 14 by soldering, or other suitable means, and the other end of the spring 25 is secured to a washer 26, having a turned flange 27 around which flange the spring is clamped, thus holding the washer 26 and spring from falling out of the casing when the cap 7 is separated from the section 6. Said washer 26 is made of insulating material' and prevents the spring 25 from making contact with the end of the cell 10. The central opening of the washer 26 is of sulicient diameter to allow the contact pin 16 and sleeve 15 to extend through the washer, as shown in Fig. 2.
The sections 6 4and 7 of the casing are adapted to be locked together by the stud, or pin 12, on the section 6; the section 7 may vary slightly iny having slots formed therein to receive the stud l2. The section, or cap 7, has an outwardly pressed rib 30 forming a longitudinal passageway for the stud 12, which communicates with a slot 3l extending at right angles to the rib BO. The cap 7 is provided-` with a longitudinal slot 33 with which the slot 31 communicates laterally at a point midway between the ends of the slot The stud l2 may enter the slot 33 through the groove formed by the rib 30 and the lateral slot 3l when it is desired to attach or detach the casing section 6 and 7.
Then the section or cap 7 is placed upon the section 6, the stud l2 may slide in the longitudinal slot 33 which will permit the sections G and 7 to be moved into the positions shown in Figs. l and 2, and make or break the electric circuit. The section or cap 7 is provided with enlarged recesses Seland 35 located at the ends of the longitudinal slot 33, into which recesses the stud may be moved by rotating the sections (i and 7 relatively. Shoulders 37 and are thus formed at opposite ends ot the slot 33, which are adapted to hold the pin l2 locked against longitudinal movement unless released rom the shoulders by rotating the sections of the casing.
When the pin l2 is engaged by tne should der 37, as shown in Fig. l, the parts will he locked against longitudinal movement, thus preventing` an accidental completion of e circuit. When the pin l2 is engaged by the shoulder 38, as shown in Fig. 2, the parts will be locked in a position in which the circuit is completed and a continuous illumination of the lamp will be maintained. llVhen the stud l2 is in the slot 33 the cap 7 may be moved longitudinally upon the section 6 to make contact between the pin 16 and the cell l0, and when the cap 7 is released the spring 25 will automatically move the cap and break the contact between the pin 1G and the cell l0. The casing section 7 forms stops 39 and l0 located at opposite ends of the slot 33, and thus limits the longitudinal movements of the section or cup 7 upon the body section The sections G and 7 may be locked together in a given position, as shown in Fig. 2, and the spring 2() will insure the contact pin i6 being held against the cell l0 and also compensate Ytor cells which mayY vary in length.
l claim 1- ii, 'flash lamp comprising a casing, a lamp mounted within the casing, a battery cell within the casing, sail casing comprising telescopinjf' sections, a washer ot insulating material located at one end of the cell, a spring interposed between the washer and the section opposite to that in which the cell moui'ited tending to torce the cell against the lamp and tending to separate said sections a contact pin mounted upon one of said sections adapted to make contact with the cell when said sections are moved against .l i action of the spring, and a locking device upon said sections adapted 'for limiting the relative longitudinal movement ot the sections.
ln testimony whereof l aliiX my signature.
