PARKING LAMP.

Application filed March 31, 1923. Serai No. 628,998.

To all whom t may concer/n.'

Be it known that I, CHARiits E. GODLEY, a citizen of the United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Parking Lamp, of which. the following is a specification.

This invention relates to electric lamps which are mounted on the left rear fenders of motor vehicles, usually at the highest point thereof, and are provided with front and rear lenses of different colors in order to indicate the positions of such vehicles; and the object of this invention is to produce a lamp of this character which c-an be assembled and disassembled without the use of tools, whose metallic parts shall all be completely machine-made, and which will permit the replacement of the light bulb with the least amount of labor.

' This invention is illustrated in the accompanying drawing in which Fig. 1 is a front elevation of this improved parking lamp. Fig. 2 is a section on the line '2 2 of Fig. 1. Fig. 3 is a plan of the pedestalportion of this lamp. Fig.- 4 is a side elevation of the upper end of the pedestal. Fig. 5 is a front elevation of this upper` end with a connector sleeve -in position. Fig. 6 is a section` on the line 6 6 of Fig. 1. Fig. 7 is a front elevation of the lower portion of Y the lamp body. Fig. Sis an inside elevation of a lens ring. F ig. 9 is a perspective view of a connector bar. Fig. 10 is a plan of a connector plug.

Similar reference characters refer to like parts throughout the several views.

As stated above, each of the metallic parts of this lamp are machine-made, that is, hey are stamped and drawn to size read .for assembling and these parts are put together without theuseof ^screws or keys. Each part interlocksfwith the" adjacent parts and is spring-held in `position vto prevent rattlin f f Ttlgie barrel shaped body lof the lamp has its ends closed by the lens rings 2 and the lenses 3 supported thereby. Ilprefer to se'- cure the lenses in position in `the rings by pressing the outer edges 4 thereof onto the glass. The` cylindrical rings are-` formed with holes topermit the ears'5 of the springs 6 to project, which ears engagethe inclined inner surfaces of the bodyat its ends and thus hold the lens rings and lenses in posiflange 10 at its upper end, and with the upwardly projecting cylindrical flanges 11. At the middle portion of these cylindrical flanges 11 are the small ears 12 which are adapted to extend into the notches 13 formed in the circular flange 14 at the bottom of a shallow circular recess in the lower side of the body l of the lamp. The upper end of the pedestal is formed to extend up into this recess as shown in Fig. 2.

A .connector sleeve 16 is adapted to slide up within the cylindrical flanges 11 and is formed with a radial circumferential flange 17 at itsl lower .end which supports a coil spring 18. This spring presses against the lower side of the flange 10 of the pedestal. The connector sleeve is formed with bayonet slots 19 to receive the pins 20 on the base 21 of the light bulb 22. This sleeve is also v formed with short inclined slots to permit the inclined upper ends 24 of the connector bars 25 to project through. The lower ends 26 of these bars are bent inward to limit the downward movement of the well known connector plug 27 which is of insulating material and has a. spring held contact pin 28 at its upper end to engage the contact 29 on the base.21 of the light bulb and has a screw 30 at its lower end to secure the conductor wire 32. The plug lis also formed with longitudinal grooves 33 to receive thefbars 25.

To assemble the lamp, the spring 18 is. placed on the connector sleeve 16 and that is slipped into the flanges 11 of the pedestal from below. The connector bars are then positioned with the inclined ends 24 above the ange 10 of the pedestal and between the anges 11, and the plug 27 is pushedL down into the sleeve 16 from above. The light bulb may now be inserted. The assembled lenses and lens rings are attached to the body land that is then so placed on the pedestalthat the ends 24 of the connector 25 pass through the notches13, after which the body is turned to the right. one fourth rotation. The flange 14 of the body will slide under the inclined ends 24 until the notches'13 register, with the ears 12 on the pedestal which will prevent the bodyff-rom turning back except-under considerable pressure.v When.

a light bulb is to be replaced the-body is turned one fourth rotation in either direction to bring the notches 13 into registration with the inclined ends 24 ofthe connector bars when the body may be. lifted off the pedestal.

The base flange 9 must be shaped to fit its support but all the other parts of the lamp may be interchangeable. The proportions and details however may all be changed by those skilled in the art without departing from the spirit of my invention as set forth in the following claims:

I claim:

1. A lamp comprising a body and a pedestal, the body being barrel shaped with lenses in its ends and having a circular recess intermediate its ends and a hole at the middleof the recess, the pedestal having a circular upper end adapted to fit said recess, a connector sleeve mounted in the pedestal and extending into the hole in the body, engaging members mounted in the sleeve and engaging the body to secure Ythe body to the pedestal, and resilient means to hold the `sleeve in position.

2.A A lamp comprising a body and a pedestal, the body and pedestal having interlit- 'ting parts, resilient means embodying a sprmg, a connector sleeve and connector bars for securing the body to the pedestal, and lenses for closing the ends of the body.

3. A lamp comprising a barrel-shaped body, lenses and lens rings for closing the ends of the body, said body having a circular depression intermediate its ends, a pedestal having an upper end adapted to t said depression, a connector sleeve mounted in the pedestal and extending into the body and vadapted to receive a light bulb at its inner end, and means including a spring and inclined members projecting from the connector sleeve .for detachably securing the body to the pedestal.

4. A lampcomprising a body, having a tapering open end, a lens for the open end of the body, a lens ring to support the lens and having a portion extending into the body,
