:E'Jll-LGA'QN forming part of Letters Patent No. 571,792, dated November 24, 1896.
Application filed March l2, 1896. Serial No. 582,351. (llo modell T0 @ZZ whom, t may concern:
Be it known that l, HENRY R. @UIN-BY, of Rochester, in the county of Monroe and State of `blew York, have invented a certain new and useful Improvement in Electric Lamps; and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had tothe drawings acn companying this application.
My improvement relates to means for controlling t-he feed of the upper carbon; and it consists in the combination and arrangement of parts hereinafter described and claimed.
in the drawings, Figure l is a central ver tical section of an electric lamp, showing my improvement. Fig. 2 is an enlarged vertical section of a portion of the same, showing the apparatus for regulating the feed o the upper carbon. Fig. 23 is a horizontal section of 2 in line es et of the last-named iigure.
rlhe object is to control the feed of the up per carbon as it is burned. away and insure its standing at the proper relation. with the lower fixed carbon.
A is the exterior casing ci the lamp, i5, the globe; C, the tubular magnet, and D the cylindrical armature which moves n p and down in the magnet.
E is the fixed carbon at the bottom el the lamp, and F the movable carbon, the latter extending up centrally through a passage in the armature and being free from contact therewith, so that there is no escape of electricity from the carbon to the armature. ln the bottom of the armature are three er more inclined. runways a a a, in. which lie or other non-conducting balls b h l), whose tendency is to slide down the runways and clamp against the carbon, thereby holding th e latter elevated.
Beneath the armature is a head Gf, provided with a projecting tubular stop c, Vhrongh which the carbon runs freely, said. stop c be ing annular and striking into the lower end of the armature when the latter is lowered. lVhen the stop so enters the passage at the bottom ot the armature, it strikes the balls hl) b and throws them out away from contact with the carbon F and allows the latter to fall. Then the armature is raised again, it clears from the stop and the balls fall back. to place, clamping the carbon and holding it up.
By the means above described the feed of the upper carbon is controlled with great regularity. YWhen the armature falls by a decrease in the electric power, the balls are ree leased from the carbon and the latter is allowed to fall. Then the armature rises by increase of the electric power, the balls close on the carbon, clamping it in place, and the carbon then rises with the further rise oi the armature until the arc is in a normal condition, when the carbon becomes stationary.
rlhe lower end of the movable upper carbon F rests between a set of balls d d d, located in cap H, screwed to the lower end of the head G, said balls resting on a slight inoline to keep in contact with the carbon at all times, but allowing free passage of the carbon up and down. They are located at such a distance from the upper balls that the two sets of balls practically hold the carbon in a true vertical position, thereby preventN ing contact between it and the armature through which it runs. The balls d d d are made of carbon or other conducting material and they are designed to form conductors at all times between the carbon F and the frame in which the balls rest, so that the main circuit through the lamp shall be intact at all times.
is a glass lamp located inside the. globe l and inclesing the meeting ends of the carbons, the lower carbon being attached and resting wholly within the lamp and the upper one sliding freely through the top oi the lamp. Vlhe lamp is attached to a base o by means ol' a set-screw, so that it can be removed at any time, The base i, in. turn, is attached to a rod 7, depending from the frame to which the globe is attaclmd rlhe lower end of the rod passes :freely through the base r, and a nut is screwed en the bottom. 3y this mea-ns the lamp is adjustable vertically and can be moved up or down to adapt it to the position of the ends of the carbons, which position changes as the cai-bons burn away. rlhe rod 7 also serves as the conductor between the bottom oi' the lamp and the carbon attached thereto and the wires connected with the main line.
rEhe current enters through wire l, thence passes through wire 2 to the upper end of a spiral resistance-coil 8, thence from the lower IOO end of said resistance-coil it passes through uire #t te the Winding 5 around the magnet, thence it passes through Wire G to the cap G and to the frame H, thence through the conducting-balls (MZ d, thence through the carbons F E, rod 7, and Wire 8, to exit-Wire 9, and :from the latter to the source ot' energy.
Having described my invention, what I claim new7 and desire to secure by Letters Patent, is-A l. in an electric lamp the combination of a 'tubular magnet, a cylindrical armature resting` therein and provided with acentral passage of greater diameter than the carbon so that the carbon Will not come in. contact with the armature, a set of non-condireting` balls resting` in inelinee in the armature, clamping the carbon, astop below' the halls entering` the end el' the armature and raising` the balls Wh Y n the armature is lowered, a cap below the armature and insulated therefrom, and a set ef conducting-balls resting en slight inclines in the cap and bearing,` against the carbon, the Whole so arranged that the two sets of balls center th carbon d hold Vit from Contaetwith the magnet, andthe lower set el' balls serve a5 conductors to convey 'the current to the carbon at its lower end7 ther-cb.)Y preventing` any circuit between the carbon and the armat u re above the lower set olf balls, as herein shown and described.
9. ln an electric lamp the combination with the transparent shade or globe l), provided with the Fixed carbon it, and havin g the carbon F movable freelythrongh its top, ol." the base r to which the shade er `globe is attached, and the rod 'Tsupporting` said base and allowing an adjustment of the base up and down thereon in order to adjust the .lamp to proper 'relative positions with the ends et' the cai-bons, said red also forming a conductor, ae herein shown and described and for the purpese specified.
ln vv'itness whereof Al have hereunto eigned my name in the presence ot' two subscribing` witnesses.
