ELECTRIC-ARC LAMP.

SPECIFICATION forming part of Letters Patent No. 258,581, dated May 30, 1882.'

Application filed May 25, '1881.

To all whom it may concern:

Beit known that I, CHARLES A. HUssEY, of the city, county, and State of New York, have invented certain new and useful Improve` ments in Electric Lamps, of which the following is a specification.

Myimprovements consistin thecombination, in an electric lamp, of a single electric circuit, an electro-magnet or solenoid in said circuit, an armature for said magnet or solenoid directly connected with the lower carbon, a train of wheel-work for controlling the feed of the upper carbon, a dog for controlling said wheelwork, a lever adapted to be actuated by said armature, but so arranged that the armature may have a given range of movement before acting upon` the lever, and means for transmitting motion from said lever to said dog to effect the disengagement of the latter from said wheel-work and permit the feed of the upper carbon. The armature of the magnet-or solenoid in the above combination preferably has the lower carbon supported directly upon it, and lthe aforesaid lever may have a fulcrumpiece which is adjustable, to adapt the lamp for electric currents of different potentials, as hereinafter fully described.

The improvements also consist in the combination,with acarbon-holder and its supporting-rod, of two or more plates connecting` said holder and rod and a pivot or pivots connecting said plates eccentrically to said holder and rod, so that the plates may be swung laterally relatively to each other to adjust said carbonholder into line with the opposite carbonhold er. The said pivot or pivots may consist of a screw or screws, which also serve as a means ot' clamping the plates together after adjustment.

The improvements also consist in a novel combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a view of a complete lamp embodying my improvements. Fig. 2 is a central vertical section thereof on a larger scale, certain portions being broken away to economize space. Fig. 3 is a horizontal section of the lamp on the same scale, taken at the plane of the line :c Fig. 2. Fig. 4 is a horizontal section of the (No model.)

lamp on the same scale, taken on the plane of the line y y, Fig. 2. Fig. 5 is a horizontal section of the lamp on the same scale, taken on the plane of the line z z, Fig. 2. Fig. 6 is a vertical section of the lamp on the same scale,

taken mainly on the plane of the line o e, Fig. 2, but also through the tube in which the rod of the'upper-carbon holder moves; and Fig. 7 is a horizontal section ofthe lamp on the same scale, taken mainly on the planes of the line w to, Fig. 2.

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

A designates the frame of the lamp, here shown as of rectangular form, and made up of tubular sections united with elbows by crosspins or rivets.

B and C designate respectively the upper and lower carbons ofthe lamp.

B' designates the holder for the upper' carbon, consisting of a socket adapted to receive said carbon and a set-screw for retaining said carbon in its socket.

B2 designates a rod, to which the holder B for the upper carbon is connected. As here shown, the said holder B' is connected to its rod B2 by means of three plates, 133134135, which may be of circular form. The platcB3is affixed to the rod B2 by a socket fitting the rod and a set-screw passing the socket and impinging against the rod. The plate B* is affixed to the plate Bsby means ofa screw, a, passing through the plate B3 and screwing into the plate B The plate B5 is secured to thel plate Bby means of a screw, b, passing through thc plate B5 and screwing into the plate B4. It has the holder B affixed to it.

The screws a and b are about one-quarter of the circumference of the plates apart when the plates arecoincident with each other, and they form pivotal connections between the plates, which they respectively secure together. Their heads also serve to clamp the plates in different positions to which they may be adjusted. The said plates thus combined afford provision forshifting the upper carbon laterally into line with the lower carbon. This is of great advantage in many cases, notably when either carbon is bent longitudinally, for even if the points of the carbons, when inserted in their IOO holders, arein line, they may, after burning, become out ofline, and then one may be adjusted into line with the other. It' the plate B3 had a swiveling connection with the pla-te, B5 could be dispensed with and the holder B' affixed to the plate B4.

On the rod B2 of the upper-carbon holder is a longitudinally-arranged rack, which gears into a pinion forming part of a train of wheels or wheel-work, E, whereby the descent of the said rod in feeding the upper carbon is rendered practically uniform and reduced to the desired speed. This train ot' wheels E is inclosed in a case, D, which is connected with the frame A by means of a surrounding band, A', provided with sockets for the reception of the sections of said frame, with which it is directly connected. Between these sockets and the said sections of the frame gaskets c of insulating material are fitted, so as to obviate any electrical connection between the said case D and the frame A.

The case D is provided with removable caps D' and D2, having rims which t Within the case and are secured there by screws d. The cap D' Vhas connected with it an upwardly-projecting tube in whichvthc rod BZ of the uppercarbon holder moves.

F F' designate two metal rods (shown as made hollow) whereby the lamp is suspended. At their upper ends (see Fig. 1) they are provided with binding-screws, to which electliccircuit wire G is connected, and as they are made of metal they serve as conductors for the electric current. Between the rod F and the cap D is tted a bushing, e, to prevent electrical communication from the said rod to the cap. A plug forming the lower part of `the rod F is provided with a recess, in which ts thenaked endof a wire or conductor, H, which is insulated except at its said end. A setscrew,f, serves to secure the said end ot' the wire in place.

When it is desired to remove the cap D the screws d are loosened, and the set-screw f is also turned to release the wire H, whereupon said cap and its appurtenances may be taken ott and access to the case aorded. The capand its appurtenances may be secured by a reverse operation.

The wire or conductor H extends down through the hollow frame A of the lamp to an annular electro-magnet or solenoid, I, arranged in a case, J, which is provided with caps J' and J2, that are secured in place similarly to the caps D' and D2. This ease J is also secured to the frame A of the lamp similarly to the case D. The electro-magnet or solenoid l is mounted on the cap J2.

K designates the armature of the electromagnet or solenoid. It consists, as here shown, of a disk extending over the top of the electromagnet or solenoid, a central core or portion extendinginside the latter, and two segmental portions tting outside it. These segmental portions are employed in lieu of a cylindric portion to afford a passage for the wire or conductor H on one side.

L designates a spring jtting at one end against the central core or portion of the armature.

L' designates a screw working through the cap J2 of the shell J and bearing against the lower end ofthe spring. The spring tends to force the armature upward, and may be compressed more or less `by adjusting the screw to suit electric currents of different potentials.

The holder C' for the lower carbon consists of a socket fitted upon a rod, C2, and secured there by a setscrew, g. It is provided with a set-screw for retaining said carbon within it. The rod C2 is connected to the armature K.

M designates a lever pivoted to a fulcrumpiece, M', within the lower part of the frame A. One end extends into proximity to a tappet, T, attached to the rod C2, and hence when said rod rises the lever is shifted. The lever M is not connected with the armature K, although it is actuated thereby, and the armature and the rod C2 supporting the lower carbon may be raised some distance before the tappet T strikes against and moves the lever M. The other end is forked and embraces a notched portion ot' an upright rod, N. The upper end of this rod N is notched, and tits within the forked end of a lever, O, which is pivoted within the upper part of the frame A. The rod N is kept in place within the forked ends ofthe levers M and O by pins h, extending across the section ot' the frame A containing said rod. At the inner end of the lever O it is connected by a piece of insulating inaterial, l?, with a bar, Q, the upper end, Q', ot' which l'orms a dog or device which, by engaging with one of the wheels in the train ot' wheel-work E, blocks the latter so as to prevent it from operating and allowing the upper carbon to feed downward.

A spring', R, tends to hold the dog Q' in cngagement with the train ot' wheel-work. The case D forms a support for the wheel-work E and dog or device Q', and the lower case, J, forms a support for the magnet or solenoid I, while the lever M, rod N, and lever O constitute the means through which the armature K actuates the dog or device Q'.

The fulcrum-piece M for the lever M consists of a screw bil'ureated at the upper end and receiving the said lever within it, and a nut fastened to the frame A, receiving the lower end ot' the screw within it, and adapted to be turned from outside said frame to raise or lower the said screw.

It will be seen that all the mechanism of this lamp is concealed and protected by the hollow frame A and the cases D and J. The electric circuit extends from the wire G to the rod F, thence to the wire or conductor H, thence through the electro-magnet or solenoid I, thence tothe cap J2 of the shell J, and thence through the case J and its cap J' to the rod C, holder C', and lower carbon, G.

extends to the upper carbon, B,thence through the holder B, plates B3 B4 B5, and rod B2 to the cap Dl of the case D, and thence through the rod F to the circuit-wire G. As soon as a current of electricity is sent through the lamp the electro-magnet or solenoid attracts the armature K, and thereby draws down the lower carbon and forms the voltaic arc. When by the burning away of the carbons the arc becomes materially prolonged the resistance in the electric circuit thereby becomes augmented, and the electromagnet or solenoid consequentlyis weakened. The spring L then raises the armature and also the lower carbon, thereby shortening the voltaic arc. When the armature rises sufficiently it rocks the lever M, and thereby releases the dog Q from the train of wheel-work E, permits the rotation of the train of wheel-work, and allows the upper carbon to feed downward.

As the upper carbon descends the are is shortened, the resistance in the circuit is reduced, and the electro-magnet or solenoid recovers its normal strength. The lower carbon is then drawn down, and the spring It draws down the dog Q into engagement with the train of wheel-work and stops the feed of the upper carbon. Thelainp continues to operate in this way, and the carbons are kept in the proper relation to cach other. When the currentot'electricityis stopped the spring L raises the lower carbon, and through the lever M and the mechanism with which it is connected the dog Q is made to release the train of wheelwork and permit the upper carbon to feed down to the lower carbon. The lamp is thus4 left ready for further use when the current of electricity starts again, for als soon as the current starts the solenoid I draws down the lower carbon and establishes the arc between it and the upper carbon. The screw L provides for adjusting the spring L so as to adapt the ar mature for use with electric currents of differ- The adjustable i'ulcruin-picce M for the lever M also provides for adapting the lamp to electric currents of different potentials and to burn with a longer or shorter voltaic arc.
