SIGNAL LAMP Filed June 13, 1927 liatented ca. "6, 1931 UNITED STATES PATENT Fries LESLIE O. PARKER, on ANDERSON, INDIANA, ASSIGNOR T DELCO-REMY CORPORATION; OF DAYTON, OHIO, A CORPORATION or DELAWARE SIGNAL LAMP Application filed June 13,
This invention relates to combination stop and rear end signal lamps for automotive vehicles, and more particularly to the type of lamp having two light chambers illuminated by one incandescent bulb having two spaced filaments differing in candle power and disposed respectively in the light chambers. The light chambers are closed by panes or lenses providing when illuminated, the stop and rear end signals, respectively.
One of the objects of the present invention is to provide a lamp of this type which is durable and rugged and which may be produced at low cost.
Further objects and advantages of the present invention will be apparent from the fol lowing description, reference being had to the accompanying drawings wherein a preferred embodiment of one form of the present invention is clearly shown.
In the drawings:
Fig. l is a front view of a the present invention.
Fig. 2 is a sectional view on the line 2-2 of Fig. 1.
Fig. 3 is a view lamp embodying with the lamp door removed looking in the direction of the arrow 3 in clinch washer which Fig. 4 is a fragmentary view showing the studs or screws to the switch case.
Fig. 5 is a view of the lamp socket and connector shell22 viewed in the direction of the arrow 5 in Fig. 2.
The lamp housing has its back wall apertured to receive a connector member comprising sheet metal half shell members 22a and 22?) attached as shown in Figs. 2 and 5' is attached by a rivet 220. The connector 22 which surto the flange 23 of the housing 20 rounds the aperture in the housing back wall.- The flange 23 cooperates with the rivet 220 to maintain the members 22a and 22b assembled. The connector 22 provides a socket 24 for receiving two terminal type electrical connection plugs (not shown) adapted to engage contacts 25 and 26 integral respectively with leaf spring conductors 27 and 28 which are insulatingly supported by a bodyof insulating material 29 within the conby the housing back secures the mounting;
the housing 20. The frame 53 is 1927. Serial ITO/198,403.
nector The electrical plug connector is retained inthe socket 24 by the usual bayonet slot and pin connections, the bayonet slots in the half shell members 22a and 22?) being.
located respectively with-.. 36 and 39 which are sep-' bayonet slots 31a in the shell members 22a and 22?), the lamp terminals engaged respectively by the 27 and 28.
The partition 40 is provided with an opening 41 through which the lamp bulb 33 eX-v tends, and is provided with an ear 42 having a square hole 43 in alignment with a square hole in the back of the housing 20for receiving the square portion 44 of a bolt 45 which is retained by clinching tangs 46 provided wall against the shank of the bolt as shown in Figs. 2 and 4. In like manner a bolt 4'? is secured to the lamp hous- 37 and 38 being spring contacts Y ing 20. The bolts 45 and 47 provide means for attaching the lamp housing to a bracket Adjacent the front edge of the housing 20 the partition 40 is provided with ears 50 havingtapped holes 51 eachfor receiving a screw 52 which secures the lamp door frame 53 to provided with apertures 54 and 55 for exposing the lenses or. panes 56 and .57 which cover respectively the light chambers 36 and 39. When the screws 52 are tightened, theflange 58 of the lamp door frame 53, which serves as a bezel ring, clamps the edges of the panes 5 6 and 57 and a sealing gasket 61 preferably of cork against the inwardly turned flange 60 of the lamp housing 20.
secured to the housing by the partition 46,
and the partition is supported at its front edge by the door frame.
The lamp panes 56 and 57 are made of any suitable transparent material such as pyralin stained or otherwise colored with transparent pigment Thus the lamp door is,
to the desired color of redf loc -rear-end or tail signal .illumination of the pane a plurality otcontacts on contact fingers arranged -t1on and having'th e1r ends axially spaced for engagement with The letters of the word Stop show by transmitted light either a deeper or a lighter shade of red than the back ground provided by the main portion of the pane 56. The filaments 34 and 35 have a common ground connection to the storage battery or the current source of the lighting system ofthe automobile through the lamp base 32, lamp socket 31, and housing 20 which is connected with the automobile frame, and the filaments 3i and are connected respectively with the terminals 87 and 38. A brake pedal operated switch is used to complete a circuit from the terminal contact 25 toa current source in order that the filament 3i will burn to 'illuminate the stop signal when the brakes are applied. .The filament 35 is connected with a current source board completin g bya switch at the instrument a circuit with the current source and the contact 26 in order that the will be visible by the 57. Preferably the filament 85 is of lower candle power since it is operated continuously when driving or parking at night, and the filament 34: is of ;-l1igl1er candle power for rendering the stop lamp plainly visible even when operated in I the daytime.
The-filament 85 is used also to illuminate the rear license plate of the automobile by shining through a pane 7O enclosing anaperture 71 in the bottom of the lamp housing 20.
A cork gasket 72 is located between the pane 70. and the bottom wall of the housing and 1s a secured in position by clamp brackets73 held by screws 7 k \Vhile the form of embodiment of the present invention as'herein disclosed, constitutes a preferred form, it is to-be understood that other forms might be adopted,-all coming within the scope of the claim which follows.
\Vhat is claimed is as follows:
Alamp socket comprising a pair of similar semi-tubular members secured together to'tormangularly related'bores, one of said bores beingadapted to receive a lamphaving the base thereof, aninsulatingplug secured in the other memher and provided with aplurality of spring in superposed relathe contacts. In' testimony whereof I hereto attiX my sig- LESLIE O. PARKER.
