einenrr-cormnw':nel DEVICE. I
Application led April 17, 1922. Serial No. 554,268.
My invention relates to circuit continuing devices and will be fully explained in connection with the accompanying 'dra-wing.
Fig. 1 is a longitudinal sectional view 5 illustrating enough of a headlighting or other refiecting lamp constructed in accordance with the invention and Fig. 2 is a view inl elevation.
The plug 1 carries spring pressed Vconltacts 4 that project from spring barrels 2 said plug being receivable in a shell 11 upon a sutticent depression of the pins 5,A thatare carried by the plug into the plug. These pins, instead of engaging the usual bayonet l slots in the shell aresnugly receivable in the formations or passages 12 in the shell whereby the shell and plug are prevented from having material relative movement. IVhen the plug has been assembled with the shell by the reception of the pins 5 in the openings 12 each contact 4 is in position to be engaged by the complemental contact upon the inner end of the base of an inserted incandeseent lamp which carries bayonet pins receivable within slots 16. 'lVhen the circuit continuing device is embodied in a reflecting lamp structure the reflector 17 of the lamp has` a rearwardly extending cylindrical holder 18 which is provided with an opening or passage 19. The shell 11 is received in the holder, one of the pins 5, preferably longer than its companion, projecting into the passage 19 whereby this pin not only effects assembly between the plug or contact carrier 1 and theshell 11 but also eects assembly between the'shell and holder. As illustrated, the holder 18 extends longitudinally of the lamp axis and in order that the incandescent lamp held in' the forward end of the shell 11 may be focused, the opening 19 is elongated and extends longitudinally of the holder to permit the shell and the parts assembled therewith to be moved longitudinally of the lamp axis and with respect to. It will be seen that the hollow the holder. i holder 18 is cut away opposite slot 19 to provide a clear space, the shell 11 having its two opposite openings 12 in register with said slot and clear space. The plug received in shell 11 has an opening extending transversely therethrough and in register with the aforesaid slot, clear space, and the opposite openings in the shell, said opposite openings being narrower than the transverse opening in the plug. The pins 5 are headed and their ShanksY pass through the opposite openings in the shell. The pin heads are larger than these openings and engage the inner side of the shell. The single spring 10 is received in said transverse opening in the plug and presses outwardly upon said pins.
While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise'details of construction shown as changes may readily vbe made without de# parting from the spirit of my invention, but having thus described my invention I claim yas new and desire to secure by Letters Patent the following: Y
A circuit continuing device including a hollow holder having a longitudinal slot in one side and cut awayopposite said slot to provide a clear space; a shell received in said holder and having two opposite openingsvin register with said slot andl clear space; a plug received in said shell and having an opening extending transversely therethrough and in register with the aforesaid slot, clear space,.and lthe opposite openings in the shell, said opposite openings being narrower t-han the transversevopenings in the plug; headed pins whose shanlrsfpass through said opposite openings in the shell and whose heads are larger than these openings and engage the V inner side of the shell; and a single spring vreceived in said transverse opening and pressing outwardly upon said pins.
In witness whereof, I hereunto subscribe my name this 26th day of March A. lD., 1920 HARRY v A. DOUGLAS.
