Description

UNITED' STATES PATENT OFFICE.
CHARLES F. SPENCER, OF ROCHESTER, NEW'YORK.
LAMP.
SPECIFICATION forming part of Letters Patent N o. 231,688, dated August 31, 1880.
` Application filed January 15, 1880. I
To all whom t may concern:
Be it known that I, CHARLns F. SPENCER, of the city of Rochester, county of Monroe, and State of New York, have invented a certain new and useful Improvement inv Lamps; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, in which i Figure 1 is an elevation of a lamp supported by my improved holder and forming a bracket-lamp. Fig. 2 is a longitudinal horizontal section of the holder.
My improvement relates to holders for lamps,
by the use of which an ordinary stand-lamp may be used as a bracket-lamp.
The invention consists of the combination, with the hollow standard, of adjustable jaws for clamping the standard of the lamp and a screw for operating the jaws.
In the drawings, A represents the base of the holder, which may be round, square, or of any other suitable form. On the back side of this base is cross-wire or other device, a, which catches on a hook in the wall, as shown in Fig. 1.
B is a projecting standard attached to the base, made hollow, and C C are the ljaws or forks by which the lamp is supported. These jaws are made as shown in Fig. 2, in which case the two jaws pass through an opening in the end of the hollow standard, and have shanks b b, which extend inward, and are attached to a block, c. This block has a female screw, through which passes a male screw, D, which passes back through the base A, and
has on the back side a shoulder, d, and a thumb-piecehf, by whichit is turned. As the screw D is turned forward or back the jaws C C will be correspondingly thrown in or ont through the socket in the end of the standard. The ends of the jaws which rest in said socket are inclined, as shown at g g, and the shanks are made of spring metal, so that as the jaws are drawn in by the screw they will be clamped together to bind upon the standard of the' lamp, and as thejaws are forced out they eX- pand by their own elasticity and release the lamp.
By the use of the holder above described an ordinary stand-lamp may be at once converted into a bracket-lamp, thereby saving the expense of two separate lamps for the purpose or a lamp which is specially constructed for that purpose.
Having thus described my invention, what witnesses.
CHAS. F. SPENCER.
