CARBON-HOLDER.
SPECIFICATION forming part of Letters Patent No. 508,314, dated November '7, 1893. Application tlledJanuai-y 18, 1893. Serial No. 458.773. (No model.)
To all whom it may concern.-
Be it known that I, CLARK C. HILL, of Newport, in the county of Newport and State of Rhode Island, have invented a new and Improved 1Carbon-Holder, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a side elevation of the upper and lower carbon holders. Fig. 2 is an inverted plan view of the upper carbon holder. Fig. 3 is a plan view of the lower carbon holder. Fig. 4 is a vertical transverse section of the upper carbon holder, the section being taken on line 44 in Fig. 2; and Fig. 5 is a vertical transverse section of the lower carbon holder, taken on line 5-5 in Fig. 3.
Similar letters of reference indicate corresponding parts in all the views.
The object of my invention is to provide carbon holders-for the upper and lower carbons of electric lamps, which will hold them in the position of use without the necessity of employing screw clamps or adjusting screws.
My invention consists in a longitudinally slitted socket, made of spring material and provided with an encircling spring, the socket being adapted to receive the end of the carbon rod and hold it axially in line with the carbon holding rod, all as will be hereinafter more fully described.
The upper carbon holder A, consists of a cylindrical socket of spring metal, bored out at the upper end and screw-threaded to receive the carbon holding rod of the lamp. The walls of the socket are thickened at its lower extremity, and grooved circumferentially to receive the circular spring a. The
mouth of the socket is flared to facilitate the entrance of the carbon rod B, and in the socket are formed longitudinal slits b, which render the sides elastic, so as to allow the socket to adapt itself to carbon rods of slightly different diameter.
. The lower carbon holder A is like the upper carbon holder, with the exception of the screw threaded portion 0, by means of which the holder is attached to the lower part of the lamp. The said screw threaded portion is of sufficient internal diameter to screw on the boss formed on the lower part of the lamp frame. The lower holder is provided with the circular spring a, and is slotted as in the other case.
It is obvious that any desired number of slots may be formed in the holders, and that the sections of the socket formed by slotting, may be made to clamp the carbons sufficiently for practical purposes without employing the circular spring a, but I prefer the construction herein shown and described.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- A carbon holder for electric lamps, formed of a cylindrical,longitudinally slotted socket provided with thickened ends and furnished with a circumferential groove near one end, and a circular spring fitted to the circumferential groove, substantially as specified.
