J. Application October 14, 1937, Serial No. 169,019 3 Claims. (Cl. 240—103) This invention relates to re?ector means for electric lights, the‘general object of the invention being to provide means for preventing glare from the lamp and materially increasing the illumina~ tion 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 herein~ after fully described, illustrated in the accom 10 panying drawings and speci?cally 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 correspond 15 ing parts throughout the several views, and in which: Figure 1 is a sectional view through the inven tion and showing the same in use on a depend 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 51.)1 said collar. Figure 5 is a top plan view‘ showing a square shaped device. Figure 6 is a sectional view showing the inven tion 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 re?ector 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 re ?ector has a circular hole 2 in its center and from this hole the top face of the member slopes down wardly and outwardly to the periphery or edge of -i U the member. ll L) 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 ing lamp. 20 of the rods passing through ears II on the mem ber 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 ?tting 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 re?ect some of the light from the bulb upwardly and outwardly against the ceilingand walls of the room, thus illuminating the room by reflected with the spaced circular holes 2’ for receiving the 20 lower ends of the bulbs B which are carried by the ?xture 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 ?rst form of the invention and the part I4’ :1. is made large enough to extend beyond the bulbs so as to- receive the light from both bulbs. The supporting rods Ill’ pass through holes in the parts X’ of the ?xture as shown. In other re spects this form of the invention is similar to ;~;_ that ?rst described and it is to be understood that the invention. can be used on ?xtures con taining one, two or more bulbs and, of course, the device will be made to conform to the arrange ment of bulbs carried by the ?xture. 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 re?ecting in any suitable man ner so that it will re?ect the rays of light up be made partially translucent. While the drawings show the two members formed of glass it is to be understood that the wardly and outwardly. A frosted transparent tive upper surface for re?ecting the rays of light member 3 is formed with a depending substan from the bulb upwardly and outwardly so as to thoroughly illuminate the ceiling‘ and upper por tially semi-spherical part 4 and a ?at 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 (r: (a which long rods I0 pass, the threaded lower ends JII) If desired the member I or the member I3 can member I or the member I3 must have a re?ec tions of the walls of a room. It is thought from the foregoing descriptionthat the advantages and novel features of the inven tion 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 i 2 2,136,862 that such changes fall within the scope of the appended claims. Having described the invention, what is claimed as new is:— Cl 1. A re?ector for an electric light bulb com prising 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 10 upper face re?ective, to re?ect the rays of light from the bulb upwardly and outwardly, a second member of translucent material located below the ?rst member and having‘ a depending substan tially semi-spherical central part, the rest of said second member being ?at, means for connecting the members together with the portions adjacent the edges in contact and supporting means for the members. 2. A re?ector of the class described comprising a member having an opening therein for receiving ‘ing the outer portion of a bulb below the ?lament therein, the member sloping downwardly and outwardly at such an angle that the ?lament 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 re?ective to direct the rays of light from the bulb upwardly and out wardly, a translucent member placed below the ?rst member and having its central portion formed with a substantially depending concavo convexed part, the rest of the translucent mem ber being ?at and a channel member receiving the edge portions of the two members for connect ing the two members together. 3. A re?ector 0f the class described comprising a member having openings therein for receiving 10 the lower portions of lamp bulbs with the ?la ments of the bulbs above the member, said mem ber sloping downwardly and outwardly at such an angle as to hide the ?laments of the lamp bulbs from view of a person standing or seated in 15 a room in which the device is placed, the upper face of said member‘ being reflective, a translucent member placed below the ?rst member and having its central portion of sub stantially concavo-convexed shape and depend 20 ing from the rest of the translucent member which is ?at, a channel member receiving the edge portions of the two members therein and supporting means connected with the channel member. 25 JOSEPH THOMAS NORTON.
