To all who/2z zz may concern,.-

Be it known than] I, JAMES GASTON, a citizen of the United States, residing at Fort "North, in the eounty oi' Tarrant and State of Texas, have invented ertein new7 and useful improveinenls in Are Lamps for Locomotive HeadfLighrs, of which the followingis such n l'nll, clean', undernet description ns will enable any one skilled in the nrt to which it apperieins to nntlze and use the sinne. reference being had to the accompanying drawings, forminfo),r part of Ithis speeiiention.

My invention relates more particularly to positive-feeding are lamps, the same being accomplished lay doek-train or other suitable motor.

The oojoet of my inveniiou is to produce an are lmnp that will he uninlluenoed by the jor of the loeonioiive. 't rhen an ordinary are locomotive need-lights, this jar is suf-cient to so interfere with its Wo'rki to pre-einde are lamps from being used for suoli purposes. l

Are linups been heretofore designed for loc-,emoties inland-lights, and accomplish the above result with more or less uncertainty. My lomp possesses features which, I elnini, will seenre the resnis desired in n superior nnnr ner. l

The invention consists oi", briefly, two enrlioirenrriers. preferably nrrnnged horizontally, the i'eed oi' both being. eoiitrolled by a shaft hearing two snnrwheels, the one of larger di- :inieter then the other, so as to feed the positive'enrhon more tlnin the negative. The sind sli-.tit is rotated hy :reloek-trnin to leed the lmn-e-.irriers end the enrhons, hut is modified in its action to positively hoop the enrbons nt on nnynrying distnnee hy :in erin connected with a rorlier, whieh letter is controlled in iis :nation hy -iin and derived Circuit magnets, 1,n'ei`rrnl ly arranged horizontally, the relative ernennt ol' eurrentrpzrssing through seid ningnei's to Qontrol the apparatus lili-,ing dependent nnen the length oi' the nro, ns in ordinary are lamps.

nvenion consists, also, in eerl'nin fearuetion :rnd :n'rnngeinent and dehe iierei nnlier set forth, out in the claims sp .sn-: pnrtieulsrly pointed A@ended hereto.

(No model.)

Fig. 2 is n front elevation thereof; Fig. 3, an end elevation ot' the sinne at the lei't hand of Figs. l. and 2; Fig. 4, :in endeievntion at the right hand, of the some; Fig. 5, 2in-elevetionl oi' the sinne with the front half of the lmnp removed; Fig. (i, n side elevation of the slieft controlling the feed of' the cai-lions; Fig. 7,a side elevation of a portion oi the latter, pnrtl'y sectioned and on a larger seule; Figs. 8 and 9, respeotively.an elevation and plan of n. eut-out; Fig.10,n cross section of my carbonholder.

The saine letters of reference indicate the same parte throughout the various figures of the drawings.

A is the base in the drawings as resting upon pieces, B B.

C is a freine carried by said base and snpports the shalt D. which controls the feed of the earhons. The frame C supper a frame, E, .which carries a clock-trein for rotating said shaft.' At the forward part this frame C supports@ freine, F', which is care. fully insulated from C, ns shown in Figs. Send Lt. Above the traine li" is arranged another frame, F, which is ornniy be in eleetrienleoin iuuniention with the frznne C and other ports of the app: "eins,

The l'rznne il nud the ports e-.irried hy it are electrically separated from the nuiin portion ofthe apparatus and the frame F, the former ol' uhieh rnrries the million-feeding mel; G' and the laitier the carbon-feeding ruoli Gholh ol' which nre coupled to nud slide with the rods Il. and Il, rrspeetirely.v From the enrhoir feeding roel; (1" depends zrlninger, l. whieliby hellend-socket joint suppe holder K that elnnips the enrbon L. From the rorlion-eeding rnok G depends corresponding parts indicated hy the some letter, having the index 2 foi-supporting the carbon La. "lhese enrhons nre kept in nligunoent hy two posts, Mand ill", respectively,provided at their upper ends with anti-friction rollers, so esto eli'ord little resistance to the saine. Both 'f these posts are insulated from thehaso-pl-.ne A. From the hangers l l2 depend pivoted pieoesull and N", respectively, which carry of the appnratiis,wliiel1 is shown two wooden ts at its beek rs the enrbonv y rollers adapted to travel upon wires O' and O",

attached to the posts M and Mand supported at their outer Aends'hy any suitable means be- .youd the-apparatus.Y These rollers-and wires as'vpossible throughout.

The shaftD passes through the apparatus and carries a wheel, a', that engages with the carbon carrier'racl-t G' and is suitably insu- .lated from said shaft. This wheel has prei erably, say, twenty-four teeth. Beyond this "..wheel aand carried by the saine shaft is carrier rack Gi.

.5 another wheel, a2, of less "diameter-say fonr- .-zteen teeth-which engages with the carbon- When the shalt carrying.` vthese wheels isrotated `by the clock-train, it will cause both carbons to feed.

one, L', will be fed through a greater distance because of the lar-ger diameter of the gearwheel a which impels it.

Upon the shaftD between the frame C is a toothed wheel, b, held in place' by a collane, and a collar, d, provided. with a fiat disk, e, carryinga pawl. The tooih'edwheel b is loosely mounted ou the shaft D and has a toothed wheehf, integral therewith engaged by'the,

aforesaid pawl, so that the wheel-b (see Figl?) may turn freely in onedirection, but will i'otate the shaft when turned in the other direcl The tooth is free to slide in the end o f said crossarm, and is provided with a pin working in a slot therein to keep it from rotating and to limit its. play. It has a spring for holding it up in its normal position. (See Fig. 5.) To the arm l? =isisecured a rocker, Q, which is .supported between the frame C by screws forming a pivotal connection therefor. (See Figs. 3 and et.) Depending from one end of said rocker-arm Q' is a yoke, R, supporting the cores of main magnets S, which are wound with coarse wire and 'are in series with the main line and carbons. Fromthe other end of the yrc'icker-arru Q extends' a vibrating piece; T, pivoted to said rocker-arm at h. This vibrating piece is attached at its inner end to a small rod, t, encircled bya spiral spriugpaud having va base-plate at one end, through which the rod z' is adapted to slide in and dnt, and'ha'ving at the other end a unt,

4 between'whichand the base-plate the/spiral spring lies. By turning the nut in one or the other direction a greater or less tension is put upon the spring. By this construction it will he observed that the vibrating piece T is capable of 'a downward movement independently of the rockerarm Q, for the rod -z' and the spring surrounding it permit this action, the

baseplate of thel rod i being perforated and resting against the parallel edges ofthe rockerarm Q see Fig. 1) accommodating this function; From the vibrating piece T pivotally depends another yoke,U,ea.rrying the cotes, of electro-magnets V, wound with tine grimaud The positivein a derived circuit around the lamp. ,The cross-arm P at its lower en'd is provided with limiting stops k k, mounted in a bracket secured to the frame C. It is also provided with a tension-spring, l, and adjusting-screw,m,

supported by an angle-piece secured to the v plate A..

Vf is the positive binding-post,which is insulated from the -base-plateA, and is connected with the derived-circuit magnets U and the main magnets S. 7 n is a binding-screw for attaching the other extremity of the wire from the magnet S to the lower frame, F', carrying the carbon-feeding rack'iG, in electrical communication with the carbon L', all of which, as before described,

is electrically separated from the upper frame,

F, carrying-the'second carbon-carrier rack G2; Normally the carbons are together.

The clock-train being wound up', the current is turned on and passes from the binding-posty W,in the direction of the arrows, through magvnets S to binding-screw nupon the llower carf` bon-carrying rack-frame, and by way of this to the positive carbon L', to the second carbon, t,

L", oa the carbon-carrying rack G2, to its frame F2, and from thence to the frame C and baseplate A to the negative bindingpost X, with which the said -frarne Fz is tin' electrical connection. The carbons being together will cause an excess of current to pass throughthe main magnets S, (the derived-circuit magnets being depleted of current,) and this will energize the magnets S so strongly that they will draw down the rocker-arm Q, and iinpel the tool h g, carried bythe cross-arm P, against the toothed Wheel b, (see Fig. 5,) and by means of thc pawlengaging ratchet j', forming a part of said toothed wheel, will produce a rotation of the shaft D, which will effect reciprocation ofthe carbon-carrier rack and a separation of the carbons. The are now will begin to burn, and the tooth g will remain between the meshes of the wheel b until the are becomes abnormal, when the derived-circuit magnets V will become energized to such adegrec as to draw down the rocker Q and free the wheelv b. The said wheelbeing i'ree to turn in the opposite direction, the shaft D is .not disturbed by the backward movement of 'the tooth y, which by means of -this backward movement frees itself from thesaid wheel b; The tooth g being mounted on aspring, is also aii'orded additional facility for escaping the wheel b upon backward movement. lThe wheel b having'nowbeen liberated from the restrain ing action of the tooth g, which is drawn away from it by the derived-circuit magnets V, as before described, the clock-train now actuatcs the shaft D and slowly feeds the carbons to-u gether. The magnets S becoming now more depressed thereby until it takes well into the saine, and is then forced upward by the spring upon which it rests between the teeth of said Wheel. When the oarbons approach near together, the tooth gis impelled by the magnets S against the wheel l), and thus effects a sepairzition of the oarbons to the proper degree. it will bo seen, therefore, that the iootli g :nodiies the feeding notion of the clock-train by holding it when the onrbons are a proper dis renee apart, by actuating the sliaft i) to sep-.irate the earbons when too near together, and when the tooth is withdrawn permitting lelie clock-train to feed ille seine. attached to the end of the eross erin' l), connected with tno cross-erin bestens or post pones iiie notion of the 'iootli g corrieri upon it :is vits tension is increased or diminished, yinns regulating the length of 'the nro. between the oni'boiis.
