ELECTRIC-ARC LAMP.

SPECIFICATION forming part of Iietters Patent No. 267,691, dated November 21, 1882.

Application tiled January .'h 18S?.

To all whom it may concern Be it known that l, CHARLES A. HUssEY, of New York, in the county and State of New York, have invented certain new and useful Improvements in Electric-Arc lramps, of which the following is a specification.

Myimprovements eonsistinavoltaic-arc electric lamp comprising two carbons or conductors, between which the are is to beformed, means for impellin g them toward each other, means for connecting them so that one cannot be moved without oecasioning motion in the other, and a stop against which one of the carbons or conductors bears, all being so combined and organized that when the carbon or conductor which bears against the stop is arrested by the stop the other carbon or conductor is kept away sufficiently to form the voltaic are. rlhe stop may be of carbon or other conducting material, or of any suitable non-conducting material, and preferably will be adjustable, so as to enable the carbons to come into contact to put out the light. When adjustable an electromagnet may be employed in the lamp-circuit to actuate it and render the lamp automatic. rlhe carbons or conductors may be advantageously arranged at an angle to each other, and supported in rocking bearings. A spring or springs or the equivalent thereof will preferably constitute themeans for impelling the carbons or conductors toward each other. The means for connectingthem so that motion in one will occasion motion in the other may consist ot' gear-wheels. Then gear-wheels are employed one is preferably made adjustable cireumferentially on its shaft to provide for maintaining the carbons or conductors at different distances apart.

The improvements further consist in a novel construction of an electric lamp, whereby the base-plate, earbons, their appurtenances, and valso the globe may be detached conveniently.

1n the accompanying drawings, Figure 1 is a perspective view of an electric lam-p embodying my improvements. Fig. 2 is a view of the essential parts ot' the same on a larger scale. Fig. 3 is a plan of these parts on the same scale. Fig. 4 is a section of the lower portion of the cowl of the globe. Fig. 5 is a (No niodcLl view illustrative of the means whereby the base-plate ofthe lanip is supported. Fig. Gis a sectional view of these means. Figui' is also a sectional view of these means. Fig. S is a detail view,illustrative of au adjustable gearwheel, which is combined with the carbons. Fig. 9 is a view illustrative ot' means which may be employed for separating the carbons to start the lamp. Fig. 10 is a sectional view ot' the same, taken in a plane at right angles to that ot' Fig. 9; and Fig. ll is an inverted plan of these means.

Similar letters of reference designate corresponding parts in all the iigures.

A B designate two earbons, which are shown as of semi-cylindric shape, but may be of any other suitable forni. They are secured in sockets or holders A B', which are mounted on rotary shafts AZ B2. rlhe sockets or holders which I have shown consist each ot' two jaws, between which the lower end of a carbon tits, and, a set-screw passing through one of the jaws and impinging against the carbon, so as to clamp it against the other jaw. Applied to the shafts A2 B2 are spring-sA3 B, which tend to rotate the shafts in such directions that they will carry the upper ends of the carbons into proximity with .each other. On corresponding ends of the shafts A2132 are pinions A" B4, with which engage two gear wheels, C D, that also engage with each other.

It is obvious that each of the springs As B3, in acting to rotate the shalt to which it is ap plied, also serves, through the agency of these pinions and gear-wheels, to rotate the other shaft in the opposite direction, and consequent ly to impel the carbons toward each other. For this reason I do not confine myself to the luse of a separate spring for each of the shafts.

l will here remark that I do not desire to be restricted to the use of a spring or springs for inipelling tbe carbons toward each other, for I may tind it advantageous to use a weight or weights or other equivalent devices.

I.lhe shafts A2 BZ and the shafts supporting the gear-wheels C D, are sustained in bearings extending from metalplates P P P2, which are connected to a base-plate, I, of hard rubber or other insulating material.

Between the pinions A4 B4 and their shafts A2 B2 are placed bushings a b of hard rubber or other suitable insulating material, so that these pinions and the gear-wheels G D will not make a short circuit in the lamp. The bushing I), which is applied to the shaft B2, (see particularly Fig. 8,) has a iiange or shoulder at the inner end, and the body or main portion does not extend as far forward as the pinion B4, which tits on it. In front of the pinion there is arranged on the shaft a washer, b. A shoulder on a hand-screw, c, which is screwed into the end of the shaft, bears against this washer and serves to clamp the pinion B4 between it and the shoulder on the bushing, thereby securing the pinion in position on the shaft. The bushing b is prevented from being` forced backward on the shaft through the action of the screw by means of a shoulder on the shaft against which it bears. By loosening the screw the pinion may be adjusted on the shaft circumferentially, and by tightening the seres7 again the pinion will be retained in the position to which it is adjusted. rIhe importance of this feature will appear presently.

E designates a device against which and near its tip the tip of the carbon B rests. It

lserves as a stop for limiting the motion of the said carbon toward the carbon A. It is made in the form of a narrow strip and occupies a vertical position, as here shown.

rPhe pinions and gear-wheels are so combined with the shafts A2 B2 ofthe carbon-holders A B that when the tip of the carbon B comes in contact with the stop the tip of the carbon A will be kept sufficiently away to form the voltaic arc. By adjusting the pinion Bl on its shaft the distance between the tips of the carbons may be varied to suit electric currents of different electro-motive force.

The stop E may be made ot' kaolin or other suitable non-conducting material or it may be ot' carbon. When made of carbon it and the carbon B, which is in contact with it, will together equal in bulk the bulk of the carbon A, providing thelam p is supplied with alternating currents of electricity. If, however, the lamp is supplied with a direct current, the carbon B and the carbon-stop E may forni the positive electrode, and then they will together have double the bulk of the carbon A, so that equal lengths of both the carbons A B will be consumed. As the carbons A B are consumed the stop Eis correspondingly burned away. Hence the carbon B is constantly impelled inward, and the carbon A has a corresponding movement, so as to preserve the relation between its tip and the tip of the carbon B. The rapidityof the feed or movementof the carbons toward each other varies correspondingly to the consumption of the carbons.

The stop E is secured to a holder, E', consisting of twojaws, between which the stop fits, and set-screw inserted in one ot' thejaws, and adapted to impinge against the stop and secure it. The holder E is provided with a shank, E2, which extends through a tube, P5, fitted in the base-plate, and is provided with a hand-piece, E3, of insulating material. A screw, g, inserted in this tube and entering a longitudinal groove in the said shank, serves to guide the stop, when adjusted, and also to clamp it in position. By loosening this screw the stop may be lowered to permit the carbons A B to come together and put out the light, and by raising the stop and securing it in position by the said screw the carbons may be separated, and the voltaic are established.

The circuit-wires G G of the lamp extend down through a supporting-rod, H, to and thence through two arms or hangers, II, which depend therefrom. At thelowerend they have attached to them metallic contact-pieces, I, which complete the circuit to the plates P P. These contact-pieces are not fastened to the said plates, but simply bear on them. rIhe circuit is continued through these plates and thence to the shafts A2 B2, the carbon-holders A B', and the carbons A B.

In Figs. 9, l0, and Il I have shown an electromagnet, J, introduced into the circuit for the purpose of operating the stop E. In this example of my invention the plate P is divided into two parts, which are insulated from each other by their attachment to the base-plate.

The electric circuit extends from that part ot' the plate I on which one ofthe contact-pieces I bears to the wire of this electro-magnet, and from the wire ofthe electro-magnet to the other part of the plate P, and thence the circuit is continued, as before described. The armature ofthe electro-magnet is connected to a lever or levers, K, and the latter near their free ends are connected to a lever or levers, L, close to the fulcruni of the latter. The levers L are connected with the shank of the holder in which the stop E is secured. When the electric current is supplied to the lamp the electromagnet is energized, and, attracting its armature, raises the stop E into an operative position. When the electric current ceases the electro-magnet releases its armature, and the stop descends so as to permit the carbons A B to come together. I employ compound levers, so that the armature of the electro-magnet can impart the requisite motion to the stop.

M designates a globe of glass or other suitably translucent or transparent material. To its lower end a metal ring, 7L, is secured by means of screws t' lapping over a lip with which the lower end is provided.

N designates hooks, which are hinged to the lower ends ofthe arms or hangers H', and are adapted to be engaged with the globe-ring It, so as to support it and the globe. By swinging the hooks inward the globe-ring will be released from them, and it and the globe may be passed downward over them and so removed. The base-plate P4, when in place, bears against the lower side of these hooks and precludes their displacement. On the base-plate are lugsj, which are provided with screws k, that IIS by overlapping the globe-ring h secure the baseplate in place. As the contactpieces I are not fastened to the plates I P the baseplate and its appurtenances can be removed at any time by loosening the screws L', and it may be easily replaced when desirable.

O designates a cowl for the globe M. It may be made of sheet meta-l and of any desired form. As here shown it is adapted to slide up and down on the rod I-I.

It will be seen that by my improvements I produce a very simple and desirable lamp.
