Application filed July 7, 1919. Serial No. 309,067.

To all whom it may concern I Be it known that I, JOHN C. ROMAINE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Reflectors, of whichthe following is a specification.

The object of the present invention is to provide a reflector, principally intended-for incandescent electric lamps, which will greatly increase the light proceeding from the lamp, which will cause iridescent 'rays to be projected therefrom, and which will be cheap and simple in construction.

In the accompanying drawing, Figure 1 1s a front view of the reflector, a lamp being shown in place relative thereto, Fig. 2 1s a cross sectional view on the line 2-2 of Fig. 1; Fig. 3 is a plan view of a supporting plate in its condition after being stamped and before parts are bent out of the plane of the plate.

incandescent electric lamp, here shown as extending downward. 2 indicates a sheet metal holder forming part of my reflector. It is formed with a central hole 3 sufliciently lar e to be passed around the electric lamp 1, and from the edge of the plate around said hole extend, integral with the plate, apertured lugst, through the apertures 1n which screws 5 can be passed to secure the plate to the lamp socket 6. The outer portion of the, plate is stamped to provide a circumferentially extending series of slots 7 her shown as six in number, and a corresponding number of pairs of circumferentially extending tongues 8, outside said slots, said tongues 8 being connected to the main portion of the plate'by a narrow neck 9 be tween the slots.

11 indicates mirrors somewhat resembling hand mirrors of the usual form. Instead, however, of the ordinary handle, sufficiently long to be held conveniently in the hand, each mirror is provided with a short stub 12, the sides of which diverge outwardly from the mirror portion proper. Each mirror is of an oval shape, and its edge is formed with scallops 13, said scallops being formed, however, not entirely through the glass of the mirror, but only in the front portion thereof, the face of each scallop making an angle of about 40 with the front surface of the glass, so that the rear face of the glass Referring to the drawing, 1 indicates an tongues 8 on opposite sides of said stubs over I the stub. The sheet metal of the plate is sufliciently thick and strong to hold the mirror firmly in position, while it is not too thick or strong to render it inconvenient to bend the tongues over the edges of the stubs.

By reason of the side edges of the stubs diverging outwardly from the mirror, it re suits that, when said tongues are bent over said edges and closely adjacent thereto, they prevent the stubs from being drawn outwardly in a radial direction from the plate.

lVhen said tongues are pressed down flat upon the stubs, they hold the mirror firmlyagainst movement'in a direction at right angles to the plate.

By bending the necks along the line of juncture with the central portion of the plate, the mirrors can be arranged in planes making any angle desired with the central portion of the plate. I have found that for a depending light, intended to throw a bright illumination onto a table or the like, an angle of about 20 is satisfactory. The rays of light proceeding from the central lamp are then. reflected by the mirrors so as to converge at a point at about the level of the table when the lamp is placed about a persons head when standing.

The reason for scalloping the edges of the mirrors is that, it produces an iridescent efl'ectavhich is ornamental and attractive. The simplicity and cheapness of the means for securing the mirrors in place will be noted. This means is made from a single piece of sheet metal stamped to the proper form, and its attachment to the electric lamp and to the mirrors requires no mechanism or tools, except screws and a screw driver.

I claim 4 1. A reflector comprising a circular series 7 of radially extending mirrors spaced from each other and each having the spaced edges scalloped.

V 2. A reflector comprising a circular series of radially extending mirrors, the front portions only of said edges being scalloped.

3. A reflector comprising a sheet metal holder and a circular series of radially extending mirrors having at their inner ends circumferentially extending series of radi-' stubs with diverging side edges, the holder ally extending mirrors having at their inner having a corresponding number of pairs of ends stubs with diverging side edges, the 10 tongues folded over the side edges of the holder having a corresponding number of 5 stubs. .pairs of tongues folded over the side edges LA reflector comprising a sheet metal of the stubs.

holder having a central round hole, and a V J. C. ROMAINE.
