CARBON-HOLDER FOR ARC-LIGHTS.
Application filed February 19, 1916.
To all whom it may concern:
Be it known that I, JOSEPH GELB, a subject of the Emperor of Austria-I-Iungary, residing in the county of the Bronx, city and State of New York, have invented certain new and useful Improvements in Carbon-Holders for Are-Lights, of which the following is a specification.
This invention relates to an improvement in carbon holders for are lights, the object being to provide a holder that is arranged so that the carbon holder proper, or socket can be readily detached from its support or bracket without the necessity of taking the brackets away from the frame-work of the lamp. The details of my invention will be pointed out in the following specification in Which Figure 1 is a front elevation, partly in section of enough of an arc-lamp structure to set forth my improvement;
Fig. 2 is an enlarged sectional view of a portion of my improved carbon holder;
Fig. 3 is a plan view thereof;
Fig. 4 is a sectional view of the carbon holder socket, the section being taken on a line 4-4 in Fig. 5;
Fig. 5 is a plan view thereof.
In the accompanying drawings, I have shown a portion of an arc lamp framework consisting of the usual upright or vertical guides 1 to the top of which is secured the casing 2 within which is located the magnet and other mechanism, not shown, for lifting the upper carbon. To the bottom of the guides 1 is secured a plate 3 through which the upper carbon 4 passes to cooperate with the lower carbon 5. The usual lifting clutch for the upper carbon 4 is indicated by 6 and its lifting link by 7 The above mentioned elements are well known to those skilled in the art.
My invention consists of an H plate 8 which carries the upper carbon 4. The H plateeonsists of slides 9, 9 connected by a cross-bar 10. To the crossbar 10, I secure a socket 11 which retains the upper carbon 4. One of the features of my inventiOn consists in the novel manner of securing the socket 11 to the H plate, at the same time insulating the said two elements one from the other.
The socket 11 is secured in position by threaded fasteners or bolts 12, Fig. 2, which pass through openings 13 in the bar 10, the

Serial No. 79,315.
openings being much larger than the bolts 12. To provide a perfect insulation at the same time providing a firm securement, I provide washer plates 14 and 15 between which and the bar 10 I place insulating material 16, such as mica. To insulate the bolts 12 from the plate 14, I interpose a washer 17 of insulating material between the heads of the said bolts and the plate 14.
To secure the plates 14 and 15 to the bar 10, I provide bolts 18 which pass through openings 19 in said plates, the said openings being much larger than the said bolts.
Between the head of each bolt 18 and the plate 14 I place a washer 20 of insulating material, and between the nuts 21 and the plate 15 I place washers 22 of insulating material. The bolts 18 pass through bushings 23 of insulating material carried by the bar 10.
Should it become necessary to remove the socket 11, the bolts 12 would be removed thereby permitting the removal of the carbon 4 and its socket without disturbing the H plate proper.
To prevent the socket 11 from touching the clutch 6 when the carbon 4 becomes short and the H plate drops, I provide distance sleeves or stops 24 which surround the guides 1. To secure a terminal to the socket 11, I provide a threaded opening 25 to receive a binding screw 26, Fig. 1.
What I claim as my invention is:
A carbon holder consisting of a support, a plate on each side of said support provided with openings, insulating material interposed between said plates and said support, bolts passing through said plates and said support but insulated from said plates and support, said plates and holder being further provided with alining openings located between said bolts, a socket contacting with the under plate, and removable bolts passing through the openings last named and engaging said socket, said last named bolts being out of contact with said plates and holder.
Signed at the city of New York, New York, the 18th day of February, one thousand nineteen hundred and sixteen.
