UNlTED `STATES HARRY A. DOUGLAS, F BRONSON, MICHIGAN.
COWL LAMP.
Application filed January 27, 1921. Serial No. 440,485.
lily invention relates generally to circuit continuino; devices and also, more specilically. to cowl lamps which ind use upon the dashboards ot autoniobiles. The invention has :for its object the provision ot an iiniin'ovicd assembly ol a mounting sleeve, attachable.` 'tor example. to the dashboard ot an automobile. and a holding sleeve tor contact carriers and which holding sleeve is housed by the mounting' sleeve7 in accordance with my invention.
ln the preferred en'ilicdimen.; ol my invention there is a shell sepzfuably assembled with and within the holding' sleeve5 this shell i'zarrying;- the contact carriers that are thereby assembled in circuit continuing relation. lly this construction the contact carriers are both separably assembled with the holding sleeve. il! hen the invention is embodied in a cowl lamp the mounting sleeve is formed to support the cowl over the 'bulb ot the incandescent lamp that is disposed within the :trent end ot' the structure.
l will enpl ain my invention more fully by reference to the accompanying drawing showing; two embodiments thereof and in which Fig-1 is a longitudinal sectional View ot a cowl lamp constructed in accordance with the preferred embodiment ol the invention; Fig. 2 is a view partially taken on line 2 2 ot Fig. l with the cowl removed; Fig.
El is a :front view of the structure with the incandescent lamp bulb and the cowl removed. a part being' broken away for lack ot space; Fig. l is a view ot a portion of the structure shown partially in elevation and partially in section; Fig. 5 is a. longitudinal sectional view illustratin a modification; and Fig. 6 is a trent end view ol the structure shown in Fig. 5 with the lamp removed, a part being broken away for lack of space.
Like parts are indicated by similar characters of reference throughout the different tigures.
ln both forms ot' the invention the mounting sleeve l is provided with any suitable Fior-mation" whereby it may be secured in annular' groove that surrounds the holding sleeve, themountingr sleeve hai/'ing an annular wall 7, at its front end, which is received and held tightly between said flanges. rl`he holding sleeve l housed by the mounting sleeve, the holding` sleeve projectinnrearward)v troni its liront end, iV t which end it .is assembled with the mounting;` sleeve. 'lhe incandescent lamp Si). has its base surrounded by the liront end of the holdingl sleeve and may be partially enclosed by a. cowl 9 whose rear end mounted to turn upon and about the iront end ot the mounting sleeve l. this. sleeve beingreduced to form a shoul-l der l0 for engaging the base oli the cowl.
The structural characteristics so tar described are common to both constructions illustrated in the drawings. In the construction ot Figs. 5 and 6 the base 11 ol the incandescent lamp is provided with bayonet projections 33 that are receivable within bayonet channels 34|.- tormed directly in the holding sleeve 4. The contact carrier 14 is shown as being lixedly assembled with the holding sleeve. The construction shown in Figs. 5 and 6 is a rso-called single pole structure and in such event the contact carrier 11i carries a single current conducting element 15 with whose rear end the conducting wire 16 is assembled and whose forward end is assembled with a contact 17 forwardly pressed by a coiled spring` 18 into connection with the Contact 19 provided upon the rear tace of the base ot the incandescent lamp bulb.
In the torni ot the invention illustrated in Figs. l to 4 inclusive, the contact carriers are not directly connected with the holding sleeve but are connected with a shell 2O that is coupled with and within the holding` sleeve l so that it may be withdrawn from the holding sleeve together with the rear contact carrier 21 that may be permanently coupled with the shell. .As illustrated, this Contact carrier is provided. with a spring barrel 22 that projects laterally from the carrier 21 and into the shell 20, this springr barrel serving to'lixedly couple this shell and contact carrier. A spring 23 within the spring barrel serves to press outwardly upon an assemblingi pin 24 which projects through a circular opening in the holding sleeve l whereby the holdingsleeve and shell. together with the contact carrier 21 assembled with the shell, are separably connected with the holdin?` sleeve. By inwardly pressing;
lon
K upon thepin 24 it may be removed from engagement with the holdingsleeve to permit the shell and the contact carrier permanently assembled therewith to be Withdrawn from the holding sleeve.
The structure shown in Figs. l, 2, 3 and 4; is a so-cal'led two pole structure, in which event the contact carrier 21y carries'v two conf. tacts 25 that are forwardly pressed by coiledy springs 26 into engagement with the contacts 27. upon the inner face of the lamp baser These coiledn springs may press rearwardly upon buttons 28 which are engagea-ble within the grooves 29 formed upon the inner ends of current conducting terminal plugs 30 that are employed to connectvthe contacts 25 with the While I have herein shown and'particw larly4 described the preferred embodiment of my invention I do not wish to be limited to the. precisei details of construction shown as n changes may readily be made without de` parting from the spirit of my invention, but having thus described my invention Ivclaim asnewanddesire to secure by Letters Pat.
ent the following The combination'witha mounting sleeve havin-g an annular wall at one end; of a holding sleeve housed by said mounting sleeve 'and having two `flanges by and bee tween which said annular end wa'll, of they mounting sleeve is held; and a VShell se arably coupled with andV within the holding sleeve. f
In witness whereof, I hereunto subscribe my name this 12th day of` November A. D.,
