PAUL M. HOTCHKIN, OF CHICAGO, ILLINOIS.

REFLECTOR-SUPPORT.

Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed September 15, 1916. Serial No. 120,313.

To all whom it may concern:

Be it known that I, PAUL M. HOTOHKIN, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Reflector-Supports, of which the following is a specification.

My invention relates to illuminating apparatus and more particularly to a support or bracket whereby a reflector of comparatively large proportions may be readily mounted in conjunction with a socket carrying an electric bulb. More particularly my invention relates to industrial lighting, that is, the illuminating of factories, machine shops and other places where a number of workmen are employed and wherein a plurality of high-wattage lampsor bulbs are used and suspended from the ceiling and to which are attached suitable reflectors.

Among the primary objects of my invention are the provision of means whereby the reflector may be suspended from the lamp socket or conduit in such manner that the highest percentage of efiiciency is obtained from the source of illumination. In carrying out this object of my invention it is necessary to afford means for adjusting the reflector axially relative to the position of the point of luminosity in the lamp and this adjustability is readily accomplished by my invention. 1

Another object of my invention is the provision of a collar in conjunction with the re flector supporting device that is capable of adjustment so that it may be fitted upon conduits or upon sockets of divers diameters,

and on account of this adjustability to provide a reflector support that is capable of being mounted upon a socket or conduit already installed, without the necessity of removing the socket or unwiring the same. Further objects of my invention are to provide a support for a reflector that is positive in its operation so that the reflector and the hangers cannot be accidentally separated from each other. Further objectsof my in vention are the provision of a reflector support that is capable of ventilating or dispersing the intense heat generated by the high-wattage lamps; that is easy to operate and attach, and which is comparatlvely inexpensive to manufacture.

I prefer to accomplish the divers objects of my invention by the means and in the manner hereinafter fully described and as more particularly pointed out in the claims, reference being had to the accompanying drawings forming a part of this specification, wherein,

Figure 1 is a vertical side elevation of a socket and conduit showing a reflector secured or supported therefrom through the medium of my improved bracket or support.

Fig. 2 is a detail view of my supporting bracket, enlarged. I

Fig. 3 is a top plan.

Fig. 4: is a horizontal section taken on line M, Fig. 2.

Fig. 5 is a vertical transverse section on line 5-5, Fig. 3.

Referring to the drawings, 10 is a suitable conduit terminating in a socket, 11, of the high-wattage type, commonly known as a Mogul socket. The reflector, 12 is adapted to be supported by a suitable collar clamped about either the upper end of the socket, 11, or around the conduit, 10. This collar preferably comprises a plurality of segments, 12, preferably three in number, each of which has an upstanding flange, 13, the ends whereof terminate in radially disposed outwardly extended flanges that are tapped centrally and when said collar is disposed about the socket or conduit, suitable screws, 14, are tightened into place and firmly clamp the collar in position. Owing to the sectional segmental form of this collar, I am enabled to tighten the same upon parts having diflerent diameters and circumferences. Intermediate the radially disposed ends of the flanges, 13, the collar is provided with outwardly and downwardly extended arms, 15, the ends, 16, whereof are bent laterally in a slightly upwardly inclined direction, and are each provided with a bifurcation or recess, 17 while the ends of the parallel members of said bifurcation are bent upwardly in an oblique direction to the arm.

The neck or reduced upper portion of the reflector, 12 is preferably provided with a convex beading, 18, and a segmental ring made in three or more sections, 19, is adapted to be screwed upon this body, or, if deinner surface to correspond with and engage the bead, 18, of the reflector neck. The ends of the sections of this ring are bent laterally outwardly to provide lugs, 20, that are preferably connected together by suitable rivets or eyelets, 21, that hold these lugs, 20, in spaced relation to each other. One of these lugs is provided with a laterally or horizontally bent extension, 22, that extends toward the lug of the adjacent section of the ring, the object whereof will be hereinafter more fully pointed out. 7

Suitable hangers, comprising screw hooks, 28, are adapted to connect the ring with the collar so as to support the reflector. The hooked ends, 2 1, of these hangers are preferably adapted to engage the rivets, 21, connecting the ring segments and the upper screw-threaded portions, 25, of said hangers are passed between the bifurcations, 17, in the lateral arms of the collar. A nut, 26, is screwed down upon each of the threaded ends of these hangers, 23, and is seated upon the lateral portion, 16, of the arms of the collar, and a locking nut, 27, is screwed up against the underside of these lateral members .to lock the hanger in position. llhe hangers, adjacent their lower ends, that is, near the hooks, are preferably scored, as at 28, to indicate the proper adjustment to be made suflicient to bring the lamp socket, 11, in proper relation with the reflector so that the greatest efliciency will be obtained.

In making this adjustment, the hangers are raised or lowered until these scores, 28, are opposite the lower end of the socket. It will be observed. that the hangers are locked in the arms of the collar and the lateral member, 22, on the lips of the ring seg ments prevent the hooks from being moved downwardly or the reflector upwardly and thereby cause the accidental removal of the same.v

While I have illustrated herein a specific mode of carrying out my invention, it will, of course, be obvious to others skilled in the art, that diversmodifications or refinements of. the structure are possible without mate rially departing from the spirit of my invention. For example, the ring segments need not engage the head on the neck; the collar segments may be of any desired number, two or more; and the hangers need not be provided with hooks. I desire it understood, therefore, that all such changes and modifications are contemplated as included within the scope of my invention as .expressed in the appended claims.

What I claim is 1. Means for mounting a reflector comprising a ring adapted to engage the neck of a reflector, screw hooks, a pivotal con nection between said hooks and said ring, and a collar consisting of a plurality of segmental parts, means for adjustably securing the parts of said collar together, and means for receiving and securing said screw hooks to said collar.

2. Means for mounting a reflectorcomprising a collar formed of a plurality of radially adjustable segments, means for securing said segments together, a ring adapted to engage the neck of a reflector, and means whereby the reflector is adapted to be adjusted axially with respect to said collar consisting of pendent devices connecting said ring to said collar.
