Application October 14, 1937, Serial No. 169,019

3 Claims.

This invention relates to reflector means for electric lights, thegeneral object of the invention being to provide means for preventing glare from the lamp and materially increasing the illumination of a room or the like.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is a sectional view through the invention and showing the same in use on a depending lamp.

Figure 2 is a top plan view showing a circular device.

Figure 3 is a fragmentary top plan view of the split collar.

Figure 4; is a transverse sectional view through said collar.

Figure 5 is a top plan view showing a square shaped device.

Figure 6 is a sectional view showing the invention in use with a pair of lamp bulbs.

Figure '7 is a top plan view of this device.

Figure 8 is a similar view but showing the ends of the device rounded instead of straight.

In this drawing the numeral l indicates the reflector which may be of any suitable shape, such as the circular shape shown in Figure 2 or the square shape shown at I in Figure 5. This reflector has a circular hole 2 in its center and from this hole the top face of the member slopes downwardly and outwardly to the periphery or edge of the member. This hole is of such a size as to receive a small portion of the lower or outer part of the electric bulb. B, with the device below the filament of the bulb. The upper surface of the member I is made reflecting in any suitable manner so that it will reflect the rays of light upwardly and outwardly. A frosted transparent member 3 is formed with a depending substantially semi-spherical part 4 and a fiat outer part 5 and this member is connected with the member I by a channel member 6 which receives the edges of the two members I and 3 and the ends of the channel member are connected together by the bolt I. A slip ring 8 surrounds the lower end of the bulb socket and has ears 9 thereon through which long rods I0 pass, the threaded lower ends of the rods passing through ears II on the member 6 where they receive the thumb nuts I2. Thus these rods detachably hold the device on the lamp with the lower end of the bulb fitting in the hole 2.

Thus it will be seen that the rays of light from the bulb will pass through the member 3 which produces a subdued light and the member I will reflect some of the light from the bulb upwardly and outwardly against the ceilingand walls of the room, thus illuminating the room by reflected light and preventing glare from affecting the eyes of persons sitting in or walking around the room.

Figures 6 and I show a device for use with two bulbs and in this form of the invention the member I3 is of rectangular shape though this member may be formed with rounded ends I3 as shown in Figure 8. This member is formed with the spaced circular holes 2 for receiving the lower ends of the bulbs B which are carried by the fixture X, the holes being arranged on the longitudinal axis of the device and between the holes the circular portion of the device is straight but slopes downwardly and outwardly from this straight portion and the holes. The member I4 is, of course, of the same peripheral shape as the member I3 and is connected with the edges of said member by the channel member 6', as in the first form of the invention and the part I4 :1.

is made large enough to extend beyond the bulbs so as toreceive the light from both bulbs. The supporting rods Ill pass through holes in the parts X of the fixture as shown. In other respects this form of the invention is similar to member I or the member I3 must have a reflective upper surface for reflecting the rays of light from the bulb upwardly and outwardly so as to thoroughly illuminate the ceiling and upper portions of the walls of a room.

the advantages and novel features of the invention will be readily apparent,

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided It is thought from the foregoing descriptionthat i that such changes fall within the scope of the appended claims.

Having described the claimed as new is:-

1. A reflector for an electric light bulb comprising a member having a centrally arranged opening therein for receiving the lower portion of the bulb, said member sloping downwardly and outwardly from the opening and having its upper face reflective, to reflect the rays of light from the bulb upwardly and outwardly, a second member of translucent material located below the first member and having a depending substantially semi-spherical central part, the rest of said second member being flat, means for connecting the members together with the portions adjacent the edges in contact and supporting means for the members.

2. A reflector of the class described comprising a member having an opening therein for receiving invention, what is ing the outer portion of a bulb below the filament therein, the member sloping downwardly and outwardly at such an angle that the filament is hidden from view of a person standing or seated in a room in which the device is placed, the upper face of said member being reflective to direct the rays of light from the bulb upwardly and outwardly, a translucent member placed below the first member and having its central portion formed with a substantially depending concavoconvexed part, the rest of the translucent member being flat and a channel member receiving the edge portions of the two members for connecting the two members together.

3. A reflector f the class described comprising a member having openings therein for receiving the lower portions of lamp bulbs with the filaments of the bulbs above the member, said member sloping downwardly and outwardly at such an angle as to hide the filaments of the lamp bulbs from view of a person standing or seated in a room in which the device is placed, the upper face of said member being reflective, a translucent member placed below the first member and having its central portion of substantially concavo-convexed shape and depending from the rest of the translucent member which is flat, a channel member receiving the edge portions of the two members therein and supporting means connected with the channel member.
