CARBON HOLDBR'FOR ELECTRIC. LAMPS.
N0. 244,50L Patented July 19,1881.
' E m y ii UNITED STATES PATENT OFFICE.
JOHN" TREGONING, OF NEW YORK, AND HIRAM S. MAXIM, OF BROOKLYN, ASSIGNORS" TO THE UNITED STATES ELECTRIC LIGHTING COMPANY, OF
NEW YORK, N. Y.
CARBON-HOLDER'FOR ELECTRIC LAMPS.
SPECIFICATION forming part of Letters Patent No. 244,501, dated July 19, 1881.
Application filedFebruary 19,1881. (No model.) v
To all whom it may concern:
Be it known that we, JOHN TREGONING, of the city, county, and State of New York, and HI- RAM S. MAXIM, of the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Devices for Attaching Oarbons to a Lamp or Regulator; and we do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to accompanying drawings, which form a part of this specification.
Our invention consists in devices for attaching the carbon-electrodes to the rack-bar or sliding rod of the feed mechanism of an electric lamp, and is explained by reference to the drawings, in which- Figure 1 is a central sectional view of the holder and its flexible connecting wire or rod; Fig. 2, the same in elevation; Fig. 3, a perspective of the upper, and Fig. 4c of the lower, portions of the holder.
Wehave found that the ball-and-socket joint commonly used for attaching the carbon-holder to the rack-bar or other part of the lamps becomes easily oxidized; .and, furthermore, that it is necessary to employ some kind of clampin g device-such as a set-screw-for fixing the holder in the position towhich it may have been adjusted. To overcome these objections we construct our holder by casting it .or otherwise from some good conducting metal, andin two separate parts, A and B, and attach them to a flexible conducting rod or wire, 0, passing through their hollow centers. Each part A B has a slot along a part of its length, extending inward as far as the center to form clamping-jaws, which are drawn together by.
screws E D, passing through holes 6 d in the slotted portion, as shown. By tightening these screws the two parts of the holder are clamped securely to the connecting-wire O. The lower part, A,is provided with a socket or cup, to which the end of a carbon pencil is fitted and secured. Theupperpart, B ,is internally screwthreaded through a portion of its length, and is adapted to screw on the end of the rack-bar of the lamp. The wire 0 may extend up into the holder or rack-bar, so that it may be drawn down and utilized in case that portion which is subjected to continual bending should break ofl".
To prevent twisting or breaking the wires between the two parts of the holder, we cut out from one part, as B, a recess, G, into which fits a corresponding projection, F, on part A. The two portions of the holder should be secured not more than one-quarter of an inch apart, as this allows of all ordinary adjustments.
In the foregoing we have described the holder as suitable for use only with the rack-bar or clamp-rod of the ordinary regulator-lamps; but it is obvious that without departing from our invention this holder, with its capabilities of adj ustment and perfectconductivity, may be employed for either the upper orlower carbon, or used generally to attach the pencils to any part of the lamp desired.
Without confining ourselves to the exact form or construction of the device as shown,
What we claim as our invention is 1. A socket or holder for carbon-electrodes, constructed in two parts, clamped to aflexible connecting rod or wire, one part containing a socket for the end of the carbon and the other having suitable means of attachment to the lamp, substantially as shown and described.
2. A socket or holder for carbon-electrodes,
constructed in two parts, clamped to a flexible connecting rod or wire, one part having a projection fitting loosely in a recess in the other to prevent the twisting of the wire, substantially as shown.
In testimony whereof we hereunto set our hands this 18th day of February, 1881.
