DETACHABL E lNCANDESOENT-LAMP SHADE.
Specification of Letters Patent.
Application filed September 21, 1905. Serial No. 279,562.
Patented Nov. 29, 1906.
To all whom it may concern:
Be it known that I, HENRY DOLIER, Jr., a citizen of the United States, residing in the city of Philadelphia, in the county of Phila delphia and State of Pennsylvania, have invented a new and useful Improvement in Detachable Incandescent-Lamp Shades, of which the following is a specification.
My invention relates to means for cheaply and effectively applying to an incandescentlamp socket a shade or reflector which shall be capable of rotation about the axis of the lamp-socket or of the lamp for the purpose of directing the rays of light in desired directions.
To this end I may employ a reflector or shade made of sheet material, preferably steel or brass; perforated with an aperture large enough to enable it to pass over the end of a lamp-socket. An inde endent resilient ring member made preferab y, of sheet-brass, is adapted to spring over the lamp-socket and retain the shade or reflector against a shoulder on the socket, or the resilient ring membermay he s rung into the aperture in the sheet-metal s ade or reflector and the ring then sprung overthe lamp-socket, preferably engaging a bead thereon.
My invention resides in other features hereinafter described, and pointed out in the claims.
For an illustration of some of the forms my invention may take reference is to be had to the accompanying drawings, in which Figure 1 is a vertical elevational viewof a lam Y and socket, the reflector or shade and resi ient ring member being shown in vertical section, the rin member embracing a head on the lamp-soc et. Fig. 2 is a view similar to Fig. 1, except that the shade or reflector is confined between a shoulder on the lampsocket and the resilient ring member. Fig. 3 is a perspective view of the resilient ring member. Fig. 4 is a vertical sectional view of a resilient ringmember and a shade, an extension member intervening between them.
Referring to Fi 1, S is a standard incandescent-lamp soc et having the usual key K and sup orting an incandescent lamp L. At 8, the soc et S 1s reduced in diameter, thus forming a shoulder a. Upon the portion 8 is the usual bead b. A resllient ring member R (shown in perspective in Fig. 3) has'a head 0, which re isters with the head I) on the socket S. A angef is provided upon the ring member R, and between the flange f and the bead c is confined the shade or reflector A. The resilient ring member R is split or incomplete circumferentially, as indicated at g in Fig. 3. A hole or aperture of suitable size is punched in the shade or reflector A, and the resilient ring member R is sprung into it until the reflector A is confined between the flange f and the head 0. Then the ring memberR is sprung over the bead b until the beads l) and c register with each other. When in this position, the reflector A is rotatable upon the ring member R to any position around. the axis of the lamp and socket, the a erture or hole in the shade A being sufficient y large to permit easy motion.
As shown in Fig. 1, the reflector or shade A is practically a surface of revolution whose axis is in the line X X at an angle of fortyfive degrees with the axis of the socket or lamp. By rotating the shade A on-the ring R light may be directed in desired directions. By perforating the shade or reflector A at different angles to its axis light may be thrown to other desired directions.
In Fig. 2 the parts are the same as those described in connection with Fig. 1. The arrangement is diflerent, however, in that the shade or reflector A is passed over the socket end and placed against the shoulder a, where it is confined by the flange f of the ring R, which embraces the portion 8 of the socket and rests upon the socket-bead b. In Fig. 2, however, the aperture is at an angle only of 1 thirty degrees with the axis of the shade A.
In Fig. 4 the shade A has an aperture larger than in the arrangements of Figs. 1 an 2. B is an extension member or cylinder of sheet metal having spun in it a bead 7c near its lower end of larger diameter. A flange m is spun over the edge of the aperture great enough to permit the easy rotation of the reflector A confined between the bead 7c and the flange m. The shell or extension B tapers toward its upper end, Where it is turned in at n. The aperture thus formed at the upper end of member B is adapted to receive the resilient ring member R. (Shown in Fig. 3.) The ring member R may be sprung over a socket S until the socket-bead registers with the ring-bead c. The eflect is to bring the lamp filament nearer to the shade or reflector A than by the arrangements shown in Figs. 1 and 2.
From the foregoing description it is apparent that a shade or reflector of sheet material having a simple non-reinforced aperture may be quickly, efficiently, and cheaply aplied to an incandescent lamp and -its.socket m such fashion as to permit its rotation in order to throw light in desired directions.
It is apparent that no riveting, soldering,
or other permanent fastenings are necessary,
the simple resilient independent ring mem- .ber R serving to attachthe shade-tolthe" lam -socket.
'T 's construction is exceedinglyvcheap, simple, efficient, and satisfactory in opera- Obviously. the lamp-socket may be rigidly r supported .inany suitable manner, or it may "h-an by the usual .incandescent lamp cord.
