3 Claims.

My invention relates to reflectors for incandescent electric lamps and more particularly to a reflector structure to be used in connection with the miniature incandescent lamps employed for ornamental purposes, as in the decoration of a Christmas tree.

An object of the invention is to provide a reflector body of substantially rigid construction capable of being applied to a miniature lamp or in proper position. i

A more particular object of the invention is to provide a reflector body composed of a plurality of variegated thin reflecting sheets or elements of different sizes and ornamental peripheral contour, the composite reflector body being supported and held in the desired dished reflective condition by means of a sheet or sheets of material of substantially greater thickness than any of the sheets or elements composing the reflector body proper.

A further object of my invention is to provide such reinforcing sheet or sheets with a plurality of tabs extending inwardly from the periphery of the central aperture of the reflector body by means of which aperture the body is secured to the incandescent lamp socket, so as to form a series of resilient tabs adapted to engage frictionally the lamp socket and thereby hold the reflector body in proper position upon the lamp.

A particular embodiment of my invention is illustrated in the accompanying drawing in which I have shown a reflector made in accordance with my invention. In such drawing, Fig. l is a front elevation of a reflector or Christmas tree ornament embodying my invention; Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a rear elevation of the reflector; Fig. 4 is a plan elevation of one of the thin reflecting sheets having peripheral designs and of which the reflector body is constituted; and Fig. 5 is a view similar to Fig. 2 showing the position of the reflector upon an incandescent light bulb.

Referring more particularly to the drawing, in which similar reference characters identify similar parts in the several views, my novel reflector is composed preferably of a plurality of variegated thin reflecting sheets of different sizes as 6, l, and 8, the peripheral edges of which are given any desired contour, for instance, a scalloped edge or pointed as shown in Fig. 4.

Each of the sheets 6 and I has a central aperture ll] of a diameter slightly larger than the diameter of the socket element of' the incansocket so as to be frictionally supported thereon York 1936, Serial No. 72,254 (01. 240103) descent lamp bulb to which the reflector is to be applied.

Superimposed upon the sheets 6 and I is a sheet 8 of greater thickness than either of the sheets 6 or i. The sheet 8, as in the embodiment illustrated, may have applied thereto, as by glue or cement, a thin colored sheet 9. Below the sheets 6 and l is positioned a sheet H which serves as a backing sheet and reinforcement elemerit for the reflector structure. sheet or reinforcement element II is of substantial thickness, approximately the same as that of the sheet 8. In assembling the variegated sheets constituting the reflecting sheets ii, i, and 8, the latter with its colored surfacing sheet 9, with the backing or reinforcing sheet H, such sheets are joined together by a plurality of rivets l2, 12 passing through the various sheets.

The sheet 8 and the backing sheet H are provided with a plurality of hemispherical tabs 13 extending inwardly from the inner peripheral edges of such sheets to provide resilient tongues adapted to hold frictionally in position the reflector structure upon the socket element M of the incandescent light bulb l5, the edges of the tabs 13 contacting the peripheral edges of the socket element 14.

In the manufacture of the: novel reflector structure embodying my invention, the sheets 6 and l are first stamped out in large quantities in contrasting colors and with various peripheral designs. The front sheet 8 of greater thickness. than the sheets 6 and l is likewise first stamped out from large sheets of material and has applied thereto the surfacing sheet 9 having av color contrasting" with those of the sheets 6 and 'l and preferably with a peripheral design contrasting with that of either of the sheets 6 or 1.

The backing or reinforcing sheet II is similarly stamped out from large sheets of stock but such backing sheet is cut from ordinary stock, i. e. one not having a surface decorative color. However, it may preferably be provided with the same peripheral design as that of the front sheet 8 so that the same die may be used for stamping it out from stock as that used in stamping out the front sheet 8.

The apertures 10 in sheets 6 and I may be made preferably larger than the apertures of. the front sheet 8 and backing sheet II as the provision of the semicircular tabs 13 upon the front sheet 8 and the backing sheet I l is suflicient to provide a means of frictionally securing the composite refiector to the incandescent light bulb.

The reflector body constructed in accordance Such backing with my invention is more substantial and has a more finished appearance than similar devices of the prior art, primarily by reason of the provision therein of the thicker facing sheet 8 and of the backing or reinforcing sheet H so that once the reflector has been dished in the form shown in Figs. 2 to 5, such dished shape will be retained.

In applying my novel reflector body to an incandescent light bulb employed in the decoration of a Christmas tree, the light bulb is passed through the central aperture of the reflector so as to have the tabs l3 thereof engage the peripheral surface of the socket member 14 of the light bulb, whereby the ornament is securely positioned upon the light bulb and retained thereon frictionally in such proper position.

It should be noted, also, that the tabs l3 are arcuate in contour and of such dimensions and pliability as to accommodate three difierent sizes of Christmas tree lamps, namely the small size which is set up to burn in series of 8s, the medium size, which is called a candelabra size and which can burn individually, and the outdoor Christmas tree lamp size which is the large size and can be used on a regular electric light circuit burning individually.

I claim:

1. A reflector for incandescent lamps comprising a dished body constituted of a plurality of thin sheets of reflecting material, a backing sheet of substantial thickness constituted of ordinary stock and constituting a support and reinforcement capable of. retaining a cupped shape, each of said sheets having a central aperture, means for securing said sheets together, and a plurality of tabs of substantially arcuate peripheral contour extending from said backing sheet into the central aperture thereof, whereby the composite reflector body may be frictionally secured to and retained upon different sizes of incandescent light bulb sockets.

2. A reflector for incandescent lamps comprising a dished body constituted of a plurality of thin apertured sheets of reflecting material, an apertured sheet constituted of ordinary stock superimposed upon said sheets and having a thickness substantially greater than the thickness of said reflecting sheets, an apertured backing sheet of. substantial thickness and of the same material as said superimposed sheet and constituting a support and reinforcement capable of retaining a cupped shape, said superimposed sheet and backing sheet being effective to retain the reflector body in its original dished form, means for securing said sheets together, and a plurality of tabs of substantially arcuate peripheral contour extending from said superimposed and backing sheets into the central apertures thereof, whereby the composite reflector body may be frictionally secured to and retained upon an incandescent light bulb.

3. A reflector as claimed in claim 2 in which the tabs are three in number to provide three points of contact and are disposed at equal distances apart so as to grip firmly the bulb at a plurality of equally spaced points.
