LAMP-REFLECTOR.

Specification of Letters Patent.

Patented Dec. 119, 1916..

Application filed March 20, 1916. Serial No. 85,265.

To all whom it may concern:

Be it known that 1, JOHN B. CLARY, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Lamp-Reflectors, of which the following is a specification.

My invention relates to reflectors for lamps, more particularly vehicle lamps and the objects of my invention are primarily improvements over my application for lamp reflectors filed Feb. 3, 1916, Serial No. 75,929, and the objects of said improvements are: First, to provide a device to be used inconnection with the ordinary or conventional reflector which is adjustable so that it is applicable to the different sizes of reflectors; second, to provide a device of this class which is simple and economical of construction, durable, easily installed and will not readily get out of order; and third, to'simplify the construction of the reflector supports.

With these and other objects in view as will appear hereinafter my invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this specification, in which:

Figure 1 is a front view of the ordinary or conventional lamp reflector in dotted lines and showing my device mounted thereon in positionin solid lines. Fig. 2 is a sectional View thereof, and ,Fig. 3 is a sectional view through AB of Fig. 1.

Similar characters of reference refer to similar parts he main section 1, movable sections 2, 3 and 4-, and sub-reflector 5 constitute the principal parts of my reflector.

he main section 1 is semi-circular, adapt: ed to fit the inside surface of the small conventional reflector. It is provided in its top edge in the middle with a recess 1 adapted to allow room for'the lamp support. It is provided in its middle immediately below this recess with a lug 1 which extends forwardly in said lainp in a horizontal position and said lug is provided with a pair of slots 1 therein. Mounted on this lug 1 by means ventional reflector throughout the severalviews.

of the two bolts 1 in said slots is the subreflector 5 which is a concave surface reflector of small size adapted to reflect the light from the lamp upwardly against the upward surface of the conventional reflector. It is provided with a lug 5 which is p vided with a slot 5" therein adapted for the so that the lug 5" is clamped to the lug 1 by means of the bolts 1 adapting it to be adjusted in various positions relatively to the lamp. Mounted on this main section 1 are three lugs 1 which are each provided with a counter-sunk headed bolt 1 so that the outer surface of the main section 1. is smooth. Mounted over this lug and provided with some clearance is a bridge 6 and the nut l on the upper end of the bolt screws down tight on the top surface of this bridge. The lower edges of said bridge 6 engage with the top surface of the sections 2, 3 and 4 and'clamp them in certain position relatively to the main section. The intermediate section 4 it will be noted over-laps the other sections 2 and 3 so that the three sections 2, 3 and 4 may be moved outwardly to the position desired, viz., to the edge of the conupon which they are mounted and willbe clamped there by means of the bolts 1 and the bridge 6. Mounted on the intermediate section 4 on the outer edge are two lugs 4 which extend down against the flat surface of the conventional reflector for additional support of this intermediate section. The exposed or upper surfaces of the sections 1, 2, 3 and 4 are painted or covered with non-reflecting surface so that one half of the reflecting surface is deadened to prevent glare except that the sub-reflector is mounted in connection with this deadened one-half and reflects the rays of light back onto the reflecting surface of the conventional reflector.

Though I have shown and described a particular construction, combination and arrangement of parts, I do not wish to be limited to this particular construction, combination, and arrangement but desireto include in the purview of my invention the construction, combination and arrangement substantially as set forth in the appended claims. It is obvious that with this construction there is provided a reflector made in sections with deadened surface, supporting a sub-reflector, that said sectional reflector is adjustable so that it is readily applicable to the different sized conventional reflectors now in use, that the three sections 2, 3 and 4 may be moved outwardly relatively to the main section andrigidly secured in any position relatively thereto as desired -so that the same will not rattle or get out of order, that the sub-reflector 5 is also adjustably mounted on the main section so that it may be moved to various positions relatively to the lamp so that the rays of light from the lamp may be directed as desired.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

1. In a device of the class described, the combination of a semi-deadened surface element made in sections adjustable relatively to each other and a sub-reflector adjustably secured to one of said sections.

2. In a device of the class described, a non-reflecting element provided with extensible sections mounted thereon and a reflector adjustably mounted thereon.

3. In a device of the class described, a I

semi-circular concave non-reflecting surface element built in sections movable relatively to each other and a sub-reflector adjustably mounted on one of said sections whereby it may be moved in various positions relatively to the lamp for reflecting rays of light from the lamp.

4. In a device of the class described, in combination with a conventional reflector of a semi-circular main section adapted to fit therein, a plurality of sections adjustably mounted thereon provided with non-reflect ing surfaces and a sub-reflector adjustably mounted on said main section.

In testimony whereof, I have hereunto set my hand, at San Diego, California, this 13th day of March, 1916.

JOHN B. CLARY.
