Application filed August 14; 1924. Serial No. 782,095.
This invention relates to automobiles, and is illustrated as embodied in a Chevrolet having a novel cowl light arrangement. An object of the invention is to provide an inexpensive lamp and housing arrangement eliminating the usual lens by substituting therefor a projecting end of an electric bulb in the housing, while at the same time providing a cowl light which is especially neat and attractive in appearance and which can be readily assembled. Various desirable and novel features of the invention will be apparent from the following description of several illustrative embodiments shown in the accompanying drawings, in which:
Figure l is a front elevation of oneside of the cowl of an automobile, showing one cowl light;
Figure 2 is a section on the line 2 -2 of Figure 1, showing the cowl light in horizontal section;
Figure 3 is a vertical section through a cowl, showing a differently-arranged cowl li ht;
Figure 4 is a front elevation of therrear part of the lamp casing of Figure 3;
Figure 5 is a vertical section through the front part of the lamp casing of Figure 3, before it is secured to the cowl;
Figure 6 is a vertical section through a cowl, showing a third form of cowl light;
Figure 7 is a side elevation of the rear part of the lamp casing of Figurb 6; and
Figure 8 is a rear elevation of the front part of the lamp casing of Figure 6.
As illustrated in Figure 1, the various lights are mounted in the cowl 10 of an automobile, in front of and below the windshield 12 and approximately at the level-of the bottom of the windshield stanchion .14.
In the arrangement of Figures 1 and 2, the cowl is formed with an opening-for the light which is surrounded by an inwardlydrawn flange 16. The lamp casing is in two interengaging parts, the front part 18 having a cyhndrical base'20 fitting within the flan '16 and a bead 22 seated against the ,cow The base is peened or spun over to secure it to the flange 16 at 24. Inside of the base 20 is an inner peripheral head 26,
therear part 28 of the casing having a corres nding bead 30 and bein slotted'at 32 so t xtitcanbesprungintop ace.
The front part 18 of the casing is formed with an opening, through which projects a substantially spherical glass front 34 of an electric bulb of conventional construction, thus eliminating the usual lens. The bulb is held at its front end by engagement with the edge of the opening in part 18 of the casing. At its rear end, the cylindrical base 36 of the bulb, which is ordinarily of metal forming one contact for the filament circuit, is grounded to the casing and is supported by fitting within a cylindrical portion or socket 38 of part 28 of the casing. In order to permit the use of standard bulbs, having a projection 40 for the bayonet joint of the ordinary socket, portion 38 may be slotted or grooved in any desired manner to provide the necessary clearance for the projection. An insulated wire 42 passes axially into portion 38 of the casing, and is soldered or otherwise secured to an axiallyarrarfed contact 44 on an insulating washer 46. spring 48 engaging washer 46 urges contact 44 against the usual contact 50 in the base 36 of the electric bulb.
In the arrangement of Figures 3, 4, and 5, the front part of the lamp casing has a tubular flange 62 spun over the edge of a flange 64 surrounding an opening in the cowl 10, the cowl being pressed outwardly at 66 to afford room for the lamp casing. The front part 60 has bayonet slots 68 to receive projections 70 pressed outwardly at the open end of the rear part 72 of the lamp casing, to provide interengaging members holding the two parts of the casin together.
In'this arrangement, the spherical front part 34 ofthe electric bulb projects through the opening/ defined by flange 62, and through the opening in the cowl, and is held by engagement with the .edge of the 0 en? ing. The base 36 of the bulb is supporte in, and grounded to, a cylindrical portion 74 of part 72 of the casing, which portion may be slotted or grooved to provide clearance for projection 40. As in the first arrangement, contact 44 from wire 42 is urged against contact 50 of the bulb by a spring 48 engaging an insulating washer 46.
In the arrangement of Figures 6, 7, andB, the rear part 80 of the lamp casing has socured to its bottom a stam i l 82 fl ed to receive the head of a coup g 84 thre ed 7 one 0 the parts having a portion to receive nuts 86 clamping the casing to cowl 10. Part has bayonet slots 88 to receive projections 90 depressed about the open rear end of the front part 92-of the casing. The bayonet slots have teeth 94, so that the parts may be forced together more or less, yieldingly to hold an electric bulb 96 having a substantially spherical glass front 98 projecting through an opening in the front of part 92, and held'by engagement with the edge of the o ening, or by engagement with a rubber or rous gasket 100. The bulb is held at its rear end by fitting within a cup 102 of insulating material 111 a cylindrlcal .ortion 104 of part 80 the contact 106 at t e center of the base of t e bulb being grounded at 108 to the casing. Current is supplied to the bulb by an insulated wire 110 passing through the coupling 84 and soldered or otherwise secured to a collar or wire 112 encircling the base of the bulb. Portion 104 may be made slightly elliptical or eccentric to provide clearance for projection 40.
While several illustrative embodiments have been described in detail, it is not my intention to limit the scope of the invention to those particular embodiments, or otherwise than by the terms of the appended claims.
