SIDE LIGHT.

Application filled August 18, 1922. Serial No. 582,718.

To all whom it may concern.

Be it known that I, CHARLES E. GonLEY, a citizen of the United States, and residing at Detroit, in the county of \Vayne andState ofMichigan, have invented a new andImproved Side Light, of which the following is a specification;

This invention relates to that type of electric lamps which are designed to widely spread a dim light rather than concentrate such--light into a limited beam, and its object is to produce lamps of this character which shall be especially adapted for use as .the side-lights and tail-lights of automobiles 1 and for advertising purposes, and which can be constructed at low cost.

Many automobiles are fitted with a pair of small lamps near the windshield, or at practically the highest portion of the front no end of the body, and these lamps are used when parking or when driving on lighted city streets as they do not blind pedestrians and drivers of approaching vehicles. The present invention consists of a lamp of this height that the rays of light therefrom will be projected in a horizontal.plane through an angle of more than ninetydegrees on each side of the axis of the lamp.

In the accompanying drawing, Fig. 1 is a side-and Fig. 2 is a front elevation of this improved lamp. Fig.3 is a section on the line 3-3 of Fig. 2 on a large scale. Fig. 4 is a front elevation of the lamp with the lens ring, light bulb and connector removed." Fig. 5 is an edge view of the retaining spring. Fig. 6 is a detail of the lens rlng. Fig. 7 is an elevation thereof.

Similar reference characters refer to like parts throughoutthe sexeral views.

This lamp embodies a cylindrical shell 1 and a spherical rear end 2 which together constitute the casing. Within the shell 1 is fitted the light-bulb-holder which embodies a connector sleeve 3 having a perforated ,end 4 through which the conductor 5 extends from a current source. The shell 1 also has an opening 6 to permit the passage of this conductor. The connector 3 is mounted in a thimble 7 attached to a disk 8 and this thimble carries a circumferential spring 9 having an inturned end 10 which character which'shall have a lens of such.

extends through alincd slots in the connector and the thimble and thus locks the connector in position. I

Extending forward from the disk 8 is a cylindrical flange 12 which ends in an outturned rim 13 of any desired size or form against which the forward end of the shell 1 contacts. This flange preferably has a slot 14 to receive the small lug 15 on the shell to thereby hold these two members in alinement. A yoke .16 is attached to the disk 8 by means of rivets 17 and extends rearwardly clear of the thimble 7 and is drilled and tapped to receive the screw- 18 extending through a hole in the end 2 of the casing, this screw thereby securing the light-bulb holder within the casing.

Extending inwardly from the flange 12 are a series of lugs 20 adapted to enter the slots 21 in the lens ring 22. This ring is generally cylindrical but has an outwardly and then inwardly turned edge 23 which fits around the flange 24 of the beehiveshaped or domed lens 25. The slots 21 are circumferential and the metal between the slots and the rear end of the ring is looped inward at 26 to permit the passage of the lugs20 on the holder when thelens ring is inserted within the flange 12. Thereafter the lens ring is turned to bring these loops 2% out of alinement with the lugs 20. The outer walls of these slots 21 areforined with shoulders 27 to resist the movement of these lugs within the slots.

A ring 28 is positioned within the flange 12 of the holder and has resilient arms 29 which contact with the disk 8 and press this ring against the inner end of the lens rin 22. To assemble this lamp the lens is secured to the lens ring by rolling down the edge 23. The connector sleeve 3 is inserted in the thimble 7 and the spring 9 is snapped ontothc tinible with its end 10 extending into the alined slots in the connector sleeve and thimble. The ring 28 is then inserted within the flange 12, being sprung below the lugs 20, with its arms 29 engaging the disk 8. The screw 18 is now inserted to secure the holder in the lamp casing. The

lens ring 22 isinserted within the flange 12 lugs are in alinement with the slots 21, after which the lens ring is turned until these lugs are at the larger ends of these slots. Upon being released the lens ring is moved outward so that the lugs are in the path of the shoulders 27 on the lens ring and prevent further rotation.

The base 30 of the bulb 31 is inserted in the connector 3 before the lens ring is positioned and the bulb may be removed when the lens ring is taken out. The rib 32 on the casing is stationary but the rim 13 is adjustable relative thereto by means of the screw 18. The shell 1 may therefore be inserted in a circular hole in an instrument board or vehicle dash or wherever else this lamp is to be mounted, and the holder then positioned with its rim 13 on the oppositeside of the support from this rib 32, after which the screw 18 may be used to force this rib and rim toward each other to secure the lamp in position.

It will be noticed that the light-bulb 31 projects beyond the edge 23 of the lens rin and that the'dome of the lens is of suc height that the entire light bulb extends into it. The result is that rays of light are projected in a horizontal plane not only forwardly but laterally and rearwardly, the an le of illumination on each side of the axis of the lamp approximating one hundred degrees. The advantage of this wide angle is that when such lamps are used as taillamps and side-lights of automobiles they will be visible to persons approaching the vehicles at ri ht angles. The steps on the inside of the ens serve to diffuse the light through even wider angles than would a lens which is smooth on the inside.

The insulatin washer 33, spring 34: and

"contact 35 at t e end of the conductor 5 are well known and form no part of the present invention. The details and proportions of this lam may all be changed by those skilled in t e art without departin 7 from the spirit of my invention as set fort emme between the lens ring and the support to prevent rattling, and a lens in said ring.

2. In a lamp, the combination of a casing, a bulb-holder, a support for said holder mounted in the casing and embodying a transverse disk, a lens ring connected di rectly to the support for the bulb-holder, a ring engaging the lens ring and resilient arms extending therefrom and en agin disk, a lens in said lens ring, and a lightulb in said holder.

3. In a lamp, the combination of a casing having a cylindrical front end, a bulb-holder mounted in the casing and embodying an annular disk, a forwardly extending cylindrical flange at the outer edge of the disk and fitting the casing and a thimble extending rearwardly from the middle portion of the disk, a connector sleeve mounted in the thimble, a lens ring fitting within the cylindrical flange of the bulb-holder and connecting thereto, a domed lens mounted on the lens'ring, and a lamp bulb carried by the connector sleeve and extending into the domed lens beyond the front edge of the lens ring. 1

4:. In a lamp, the combination of a casing having a circumferential rib and an open end, a lamp-bulb-holder mounted in the easin and embodying a circular disk and a cylindrical flange at its outer edge fitting the open end of the casing and having an outturned edge, means to draw the flange into the casin to cause the edge of the flange and the rib on the casing to grip the suporting device between them, a lens ring fitting within the flange, a lens mounted in the lens ring, and a lamp bulb supported by the holder. a

5. In a lamp the combination of a casing, a lamp-bulb-holder mounted therein and 'embodying a circular disk having a central opening, a thimble attached to the disk at t 0 opening and a cylindrical flange at the outer edge of the disk and fitting the casing, means to secure the bulb-holder within the casing, a flat ring mounted within the flange and resilient arms extending from the inner edge of the ring and contactin with the circular disk portion of the bul holder, a lens ring slidably mounted in the flange and means to retain the lens ring within the flange, said lens ring engaging said flat ring and stressingthe arms thereon, a lens carried by the lens ring, and a lamp-bulb mounted in said thimble.
