Y c. E. GODLEY I SYIDECLAMP Filed Sept. 18; 1922 ailor'ngg CHARLES E. GODLE Y', OF DETROIT, MICHIGAN, ASSIGNOR TO EDMUNDS & JONES CORPORATION, DETROIT, MICHIGAN, A CORPORATION OF NEW YORK.

SIDELA'MP.

Application filed September To all whom it may concern Be it known that I, CHARLES E. GonLnY,

a citizen of the United States, and residing at Detroit, in the county of Wayne and'State' of Michigan, have invented a new and Im-. proved Sidelamp, of which the following is a specification.

This invention relates to the construction of electric lamps adapted to be mounted on or at the cowls or other portions of automobile bodies for the purpose of projecting rays of light toward the fronts and from the sides of the vehicles, and also downwardly to illuminate the running boards or other steps of the vehicle, and its object is to provide a lamp of this character which shall have aminimum number of parts,.which can be constructed at low cost, and which shall have a pleasing. appearance.

This invention is embodied in a lamp consisting of a tubular case having a closed rear end and having openings in its tubular wall to permit the passage of light, a tubular transparent body niounted within the body p a front elevation and Fig. 2 is a side elevation of a lamp embodying the present invention. Fig. 3 is a section on the line 3-3 of Fig. 1. Fig. 4 is a section" on the line 44 of Fig. Fig. 5 is an elevation of the supportin disk for the light bulb. Fig. 6 is a side e evation of a portion of the front edge of the lamp casing and Fig. 7 is an end elevation thereof.

Similar reference characters refer to parts throughout the several views.

The principal object of the present invention is to provide a transparent enclosure for a light bulb 1, the enclosure being so constructed that rays of light may pass from this'light bulb in several directions at any desired angleto each other and radially to the axis of the base of the bulb, and that other rays may pass from the ight bulb like 18, 1922. Serial No. 588,794.

along a path which is in alinement with the axis of this bulb base. A satisfactory transparent enclosure is produced by pressing 1glass into the form of a cylindrical body 2 avlng an end 3 of any desired configuration, that shown being in the form of a dome. The body 2 is preferably co-axial with the base 4 of the light bulb mounted in the well known connector sleeve 5.

The sleeve 5 is shown mounted in a cbnvex disk 6 having a flange 7 adapted to engage the edge of the body 2, a packing ring 8 of paper, cork or other more or less resilient material being provided if desired. This disk is forced forward by means of a spring 9 which engages the rear end 10 of the case.

This case could be merely a straight cylinder with openings to permit the rays of light to pass in the desired directions but it may .be made more ornamental and stronger by forming it with the circumferential bead 12 and then curving the metal adjacent this head and at the rear ends of the openings 13 and 14, inwardly, as shown at 15, to contact with the glass body 2. The longitudinal ribs 16 are preferably semi-cylindrical and their edges contact with the glass. The longitudinal edges of the portion 17 of the case to which the support 18 is attached, by soldering or otherwise, are also curved, and the portion 19 between this portion 17 and thead-jacent rib 16 preferably fits the glass body 2. The portion 19 is usually the top .portion of the case.

The outer end 20 of the case is in the form' of a cylindrical ring whose rear edge is curved inwardly, except at the portion 17 of. the case, to engage the glass body. It is formed with any desired number of bayonet slots 22, shown in Fig. 6, which extend from the grooves 23, shown in Figs. 6 and 7.

A ring 25 has an inturned inner edge 26 engaging the end 3 of the glass body and a rearward and inwardly turned outer edge 27 which extends around the outer end 20 of the case. Within this ring is, secured by soldering or otherwise, a band 28, which carries a pin 29 for each bayonet slot 22 in the case. The glass body is pressed forward against this ring by the spring 9 and plate 6 and is thereby securely held in position.

The support 18 may be provided with. a

.hollow extension 31 having a shoulder 39' and a threaded end 33 to receive a nut whereby the support may be attached to the ve-.

hicle. The conductor wire 35 extends through this support into the case which is preferably ribbed longitudinally at 34 to receive this conductor which then passes between the spring 9 and the end 10 of the case to the connector sleeve 5.

Thedisk 6 is attached to the sleeve in any desired manner and is formed with ears I 36 which slide along within the ribs 16 to the position shown after which the disk is turned less than 90 degrees. When the ring 25' and the glass body are removed to permit renewal of the light bulb, the forward movement of the sleeve 5 and disk 6 is limit ed by these ears engaging the inturned flange 15 of the case. As the body of glass is cylindrical it is always in proper position.

A horizontal lamp has thus far been assumed but it is evident that the lamp may be in any other desired position and that while a light transmitting opening in the end of the case will usually be desired, this is not necessary in all cases.

The details of construction and the proportions of the parts 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. In a lamp, thecombination of a cylindrical glass body having a closed forward memes end, a light bulb within the cylindrical body, a substantially cylindrical case enclosing the cylindrical body and having an end to close.

open end of the glass body, a connector sleeve mounted in the disk to support the bulb, and a spring between the disk and the end of the case to press the disk against the end of the body.

2. In a lamp, the combination of a cylindrical glass body and a glass endtherefor,

a substantially cylindrical case enclosing the glass body and having a closed end, a ring to hold the glass body in the case, a disk within the case in contact with the inner end of the glass body, a light bulb supported by the disk, a coil spring pressing the disk against the body and the body against the ring, said spring resting against the closed end of the case, and a hollow supporting arm for the lamp attached to the case to serve as a conduit for the electric wire leadingto the lightbulb.

CHARLES E, GODLEY.
