Description

L. O. PARKER ELECTRIC LAMP Filed June 13, 1927 Patented Dec. 5, 1933 1,937,912 ELECTRIC LAMP Leslie 0. Parker, Anderson, Ind., assignor to Delco-Remy Corporation, Dayton, Ohio, a corporation of Delaware Application June 13, 1927. Serial No. 198,407 2Claims (Cl. 177-829) This invention relates to rear end signal lamps for automotive vehicles, and more particularly to combinedstop and rear end signals.

One object of the present invention is to provide combined signal and stop lamp of durable construction and which. can be economically manufactured.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred form of embodiment of the present invention is clearly shown.

In the drawing:

Fig. 1 is a front view of a lamp embodying the present invention.

Fig. 2 is a sectional view on the line 2.-2 of Fig. 1.

Fig. 3 is a front view of the lamp with the lamp 'door removed.

Figs. 4, 5 and 6 are fragmentary section views on the lines 4-4, 5-5 and 66 respectively of Fig. 1.

Fig. 7 is a fragmentary sectional view on the line 7-7 of Fig. 3.

The lamp includes a housing 20 which is divided by a partition 21 into light chambers 22 and 23 containing lamps 24 and 25 respectively which illuminate a stop lens 26 and a rear end signal or tail lamp lens 27 respectively. The lenses 26 and 27 are parts of the same piece of glass 28 and are visible through suitable openings provided in a door frame 29 which provides a bezel ring 30 for engaging the flange 31 of the glass 28 and providing a flange 32 for engaging the outside of the housing 20. The glass 28 is secured with a cork gasket 33 to the frame 29 by two hollow rivets 34 each having a head or flange 35 bearing against the'outside of the frame 29 and having tangs 36 which are bent over against a washer 37 which bears against the cork gasket 33. The rivets 34 pass across notches 28a in the glass 28 (see Figs. 1 and 5). Thus the glass door frame and gasket are held in assembled relation and may be manu factured as a separate sub-assembly. The door assembly is secured to the housing 20 by screws 38 which pass through tapped holes 39 in cars 40 provided by the partition 21.

The partition 21 is secured to the back of the housing 20 by providing the partition with a bracket portion 41 which is secured to the back of the housing 20 by screws 42 and nuts 43 as shown an aperture aligned with the aperture in the bracket 41 and provided in a wall portion 20a which is spaced from the back wall of the housing 20 and which provides a support for the shell 50. The shell receives a double contact electric connector plug, not shown, but having contacts for engaging respectively contacts 52 and 53 provided by spring conductors 54 and 55 respectively which are insulatingly supported by a non-. conducting plug 56 attached to the shell 50. The electricconnector plug received within the shell 50 is retained by the usual pin and bayonet slot connections, the bayonet slot being shown at 57.

The partition 21 is provided with a central aperture for receiving the base 60 of the lamp 24 and the metal -adjacent this aperture, is formed so as to provide two diametrically opposite upright lips or flanges 61 which support the lamp against tilting at right angles to the plane of the back of the lamp housing, and with two downwardly extending diametrically opposite flanges 62, both of which are provided with a bayonet slot for receiving a pin extending from the lamp base 60 in order to retain the base within a socket provided by the flanges 61 and 62 so that the insulated terminal 64 of the lamp will be held in engagement with the spring conductor 54. In

similar manner the base of the lamp 25 is retained within a socket 71 attached to the bracket 41 by providing the socket. with tangs .72 passing through holes in the bracket 41 and bent over against the back side thereof. The socket 71 is C-shaped as viewed in Fig. 3 so as to provide an opening 73 for receiving the spring conductor 55 which engages the insulated contact 75 of the lamp 25.

The lamp is particularly adapted to be mounted upon a bracket in the rear of the vehicle, which bracket also supports the rear license plate. This bracket is provided with holes for receiving the threaded shanks of screws 81 and nuts 82 when 225 through the pane covering an opening in the bottom of the housing 20 and secured to a gasket 91 in position shown by clamps 92 and screws 93.

The lenses 26 and 27 are generally convex upon the outer surface and concave upon the inner surface. The entire inner surface of the lens 27 and the background surface of the lens 26 forming a background for the letters S-T-O- -P is ion roughened by providing a plurality of small projections or pimples which tend to diffuse the light transmitted through the lenses. The letters of Stop are formed by recesses 101, the front face or end wall 102 of each recess being defined by relatively narrow horizontal ridges or prisms 103 each having a cylindrical surface 104 tending to reflect upwardly the light rays which are projected from the lamp 24 so that the stop signal will be more plainly visible to the driver of a car in the rear of a vehicle provided with this lamp. The ridges 103 tend to break up the light so that the letters appear as if crossed by relatively bright narrow horizontal bands. The contrast between the letters and the background is obtained since the stippling provided by the tiny projections 100 tends to render the lens less transparent and the thickness of the lens from the recess wall 102 to the front surface of the lens is considerably less than from the background portion to the front surface.

A rivet 94 secures to the back of the lamp housing 20 a reflector 95 by which light from the lamp 24 is reflected toward the lens 26.

While 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 claims which follow.

What is claimed is as follows:

1. A signal lamp including a housing having its back wall formed with a dished portion, the rear wall of which is spaced from the main portion of the back wall of the housing, bolts for securing the housing to a bracket and having their heads Within the dished portion and their shanks extending through the rear wall of the dished portion, and a substantially horizontal partition member dividing the housing into light chambers and having an integral vertical bracket extending laterally beyond the dished portion with means for attaching said bracket to the main portion of the housing back wall, said partition member being provided with a sleeve attached to the bracket and extending through an opening in the rear wall of the dished portion.

2. A signal lamp including a housing having a rear wall provided with a dished portion, bolts secured to the wall of the dished portion and extending rearwardly from the lamp, a relatively wide, flat bracket extending laterally beyond and spaced from the wall of the dished portion with means to attach said bracket to the rear wall of the housing, said bracket having a horizontal portion forming a partition which divides the housing into two compartments, and a terminal supporting and connector plug receiving sleeve extending through aligned apertures in the bracket and the rear wall of the dished portion of the housing.
