SIMON H. STUPAKOFF, OF HARTFORD, CONNECTICUT.
CARBON-HOLDER FOR ARC LAMPS.-
SPECIFICATION 'forming part of Letters Patent No 340,065, dated April 13,1886.
Application filed February P, 1886.
To all whom it may concern:
Be it known that I, SIMON 11. STUPKOEF, of Hartford, Connecticut, have invented an Improvement in Electric-ArcLamp Carbon- Holders, of which the following description and claims constitute the specilication, and which is illustrated in the accompanying sheet of drawings.
This invention'is a mechanism for attaching the upper carbon to the carbon-rod, or for attaching the lower carbon toits supporter.
Figure 1 is a view of this invention holding an upper carbon to acarbon-rod. Fig. 2 is a central vertical section ot' the same. Figs. 3 and 4 are horizontal sections of the same on the lines a c and I) I), respectively, of Fig. 2. Fig. 5 is a view of the invention modified in form and holding a lower carbon within its supporter. Fig. 6 is a central vertical section of Fig. 5. Fig. 7 is a central vertical section of the lower-carbon supporter with my invention again modified and holding a lower carbon within the same.
The numeral 1 indicates the upper carbon, and 2 denotes the carbon-rod. The carbonholder 3 is permanently fixed to the carbonrod, or it may bc fixed with a ball-and-socket joint thereto, and itv is provided with a central recess for the reception of the upper end of the upper carbon, and with three converging recesses, 4, 5, and 6, surrounding the central recess, and extending to it from the outer and upper sides of the carbon-holder. These converging recesses all openinto the cent-ral recess; but those openings are of less diameter than are the converging recesses. The balls 7, S, and 9 aresmallenough to work easily in the converging recesses 4, 5, and 6, respectively, andlarge enough to be unable to pass through the openings into the central recess of the carboirholder, though they must protrude into that recess through those openings. The shell 10 incloses the spherical part of the carbon-holder 3, and is provided with the downward projections 1l, 12, and 13.
This shell may be of brass, and may be spun over the carbon-holder, so as to cover the outer ends of the converging recesses and not be removable therefrom; or the spaces which divide the projections 11, 12, and 13 may be continued upward to the equator of the spherical part of the carbouholder, so as to Serial No. 191,112. (Nomolel.)
be removable therefrom by bending the projections outwardly, or by turning the shell upon the carbon-holder till those projections reach alignment with corresponding grooves cut in the outer surface of the carbon-holder to admit the upward passage ot' those projections without bending them. So, also, the projections 11, 12, and 13 may be appurtenant to the carbon-holder 3 instead ot' to the shell 10; or, they may he omitted altogether where the carbon is otherwise sufficiently connected electrically with the carbon-rod.
The lower-carbon supporter 4 is ol' a common construction, and is provided with the insulatingannular-flanged disk 15. The lowercarbon holder 1G rests within that annular disk, and is provided with a central recess, and three converging recesses with balls therein, similar to the corresponding devices in the upper-carbon holder 3. The ring 17, provided with the projections 1S, 19, and 20, is fixed with a bayonet-joint to the upper end of the lower-carbon holder, as shown in Fig. (i, or to the lowerend thereof', asshown in Fig. 7, or to both ends thereof, if desired by the constructor.
The mode of operation is as follows: The carbon is placed in the carbon-holder by simply inserting it from below; but the three balls act as wedges to prevent its direct witlr drawal by gravity or otherwise, while they permit its withdrawal spirally. A single motion of the hand holding the carbon will therefore fix it firmly in the carbon-holder, and a compound pulling and turning motion will readily withdraw it therefrom. The upper carbon is electrically connected with the carbon-rod by direct contact and through the three balls and the upper carbon-holder. The projections 11, 12, and 13 constituteadditional electrical connection between the upper carbon and the carbon-rod, while the projections 18, 19, and similarly connect the lower carbon with the line-conductor through the binding-post 21,whieh binding-postisinsulated from the carbon-supporter 14, though mechanically connected therewith.
The three converging channels and their balls may be increased in number and changed in relative position, if desired. Three such balls Working on one plane and three others working on another plane produce a good rev V v y A sult, especially when the upper-carbon holder l the central recess wide enough to `permit the io @,1 is joiuedto, the carbon-rod by a. ball-andprotruson, but not vwide enough 4to permit socket joint. the passage of its ball thereout, all substan- I claim as my inventiontially as described. l j The carbon-holder 8, provided With a ceu- SIMON H STU'PAKOFF tml recess for the reception of a carbon, and
