ELECTRODE.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed. July 20, 1914. Serial No. 852,040.

To all whom it may concern:

Be it known that I, -CLARENOE E. McCon- LAM, a citizen of the United States of America, residing at Emporia, in the county of Lyon and State of Kansas, have invented certain new and useful Improvements in Electrodes, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to electrodes for' are lights especially adapted to be used upon locomotives and the like, and has for its object the production of a simple and eflicient electrode whereby the carbon or graphite will be protected to a certain extent by means of the metallic support or body which carries the core.

Another object of the invention is the production of an elficient electrode which is simple in construction, eflicient in operation, and which may be manufactured at a minimum cost.

A still further object of the invention is the production of a simple and eflicient means for eliminating as far as possible the forming of a crust over the end of the electrode which would be likely to prevent the correct burning of the electrode.

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing: Figure 1 is a perspective view of the electrode. Fig. 2 is a side elevation thereof partly in section. Fig. 3 is a top plan view of the electrode. Fig. 4. is a section taken on line H, of Fig. 2.

By referring to the drawing it will be seen that 1 designates the body of the electrode which is formed of a substantially tubular form and is preferably formed of copper having tapering conical ends 2. These tapering conical ends 2 terminate in flat terminals 3. The body 1 is provided at each end with a longitudinally extending ocket 4: as is illustrated in Fig. 2. The

.ongitudinally extending pocket at each end.

of the body 4 is filled with a graphite or carbon core 5, and this carbon or graphite core 5 is adapted to extend flush with the outer end of the body 1 as is clearly illustrated in Fig. 2.

It should be understood that by having the graphite or carbon core embedded within the copper body, which body may of course be formed of any suitable metal, the core 5 will be held against the possibility of a crust forming around the body portion thereof, since only the outer end of the core is exposed. Furthermore, by having the core flush with the outer edge of the body 1, if a slight crust should form upon the outer end of the core, the same may be readily and easily removed by the use of a small piece of sand paper or other scraping device. It should be understood that by means of the electrode as herein described, it is not necessary to scrape the entire core, as only a few strokes of the cleaning device will be necessary over the outer end of electrode to remove the crust from the conducting carbon or graphite 5.

It has been found by actual experience by use of the present device that the electrode as herein described will last considerably longer than the ordinary electrode employed, in that the usual crust which forms upon such electrodes will not form so rapidly thereon, as with the usual form of electrode. Further it has been found that by merely exposing the outer end of the electrode, the life thereof has been greatly lengthened, and further that the. outer end of the electrode may be readily cleaned as above described. It should be further understood that a very eflicient device has been produced wherein a carbon or graphite core In testimony whereof I hereunto affix my s1gnature 1n presence of two Witnesses.
