VOLTAIC-ARC LAMP.
SPECFICATON forming part Of Letters Patent No. 276,703, dated May l, 1883.
'A pplicntion tiled September i3, i882.
To all whom it may concern Be it known that I, OTTO A. MOSES, of New York city,in the countyand State of New York, have invented a certain new and useful Improvement in Voltaic-Arc Lamps, ot' which the following is a specification.
The object I have in view is to produce a simple and efficient automatic and continuously-actiug regulator' for arc-lamps, more especially adapted for a multiplearc arrangement, but also capable of being' used with the lamps in series or multiple series, which regulator will act positively upon the movable carbon in lifting such carbon to establish the are, and inforcing such movable carbon upon the stationary carbon when the arc is broken, the mechanical connection with the rod or tube carrying the movable carbon not being dependent upon the feeble action ot' magnetic clamps, which are liable to slip in lifting the upper carbon, the action ofthe lifting core or armature being quick and forcible. The downward -t'ced of the upper carbon, also, is not dependent whollyupon the weight 0i' the carbon and its holding rod or tube, but when the arc is -broken or increased to a definite extent beyond the normal resistance the armature or core drops, and its movement is transmitted positively tothe upper carbon, which is forced downwardlythereby. Theconnection between the core or armature and the tube or rod carrying the upper carbon is of such a nature that it is a positive connection when the moveme'nt is a quick one; but the carbon-carrying tube or rod is capable ot' a retarded downward movement, effected by its Own weight, independent ofthe movement ot' the core cr armature, and it is a further object to provide an eeetive magnetic clamping device for regulating this retarded feeding movement.
A still further object is to produce simple and efficient means for maintaining` uninterruptedly the electrical connection of the upper carbon with the circuit-wire through the moving parts ot' the regulating mechanism, and preventing bad contact, due to oxidation caused by sparks'at'points of moving contact.
The features ot' invention are fully herein after explained, and are pointedfout bythe claims.
In the accompanying drawings, forming a -with the same.
(No model.)
part hereof, Figure l is a vertical section of a regulating mechanism embodying my invention; Fig. 2, a cross-section ofthe carbon-car rying tube, showing` the top of the clampingarms; and Fig. 3, a section cfa modiiied construction.
A represents the coils cfa solenoid or hollow electro-magnet, one end oi' which is connected with circuit-wire 1, while the other end is fastened to the shell a, upon which the coils Aare Wound, such shell a being connected with the supporting' and guiding heads b c.
B is the core or armature ofthe solenoid or magnet working within and -extentled below7 the shell a. This core or armature is also hollow, and has passing through it the tube C, carryingthe upper or movable carbon, D,ot` the lamp, such tube being guided by suitable rings within the hollow core orarmaturc, and being filled with a liquid, D', preferabtv1 a viscous liquid, such as glycerine. From the core or armature B rises the tube E, passing through the head l) and extending above the same and inclosing the carbon-carrying tube C. A stationary protecting tube may rise from head l1 and inclose the tube E, it desired, as will be explained hereinafter. Brushes or springs d, carried by head b, press constantly upon the tube E, maintaining good electrical contact A rod, F, is secured to the upper end of tube E, and extends centrally down within the earbon-carrying tube, through the liquid D of the same, to near the lower end of the tube when such carbon -carrying tube is at its highest point ot movement within the hollow core or armature. Atits lowerend the rod F carries a piston or plunger, G, which, however, does not fill the tube completely, but permits a definite small flow ot' the liquid around it. rI'his piston or plunger is provided with spring-wires c, which are secured to such plunger, and spring outwardly, so as to bear constantly against the inner side of the tube C. These spring-wires Within the carbon-hold ing tube maintain uninterruptedly the connection of the upper carbon with the circuit-wire, and the liquid in which these spring-wires are submerged lnbricates the surfaces, so that the parts work smoothly, and prevents sparks at the points ot' contact. The wires e are preferably of copper, although they may be made ot' lOO a magneticmetal, and be plated with copper or not, as found desirable. rlhe piston or plunger may also be either of magnetic or nonmagnetic metal. In slots in opposite sides ot the core or armature B are pivoted vertical metallic arms H, having clamping-plates fat their upper ends, which bear against the sides of the carlmn-earrying tube C. These arms H extend below the core or armature B, and have outwardlyprojecting wings g, which carry on their ends arn'iatures i, ot' iron or other magnetic metal. The core or armature B has wings IL, which attract the armatures 1 when the core is magnetizcd. VThe wings 7a are preferably provided with adjustable pole-pieces, which may he large screws t', turning through such wings. The wings h are connected with the head c by means by spiral springs K, which are adjustably held at one end by means of set-screws la. These springs support the core or armature and the parts connected therewith, and limit as well as cushion the movement ot' said core or armature.
The operation of the regulator is astollows: Before the circuit to the lamp is completed the parts are in the position shown in the drawings. Upon completion ot'circuitthe core or armature B is magnetized and ,drawn up into the coils A with a quick and powerful action against the stress of the springs K. rEhe tube E, rod F, and plunger G are raised with the core or armature, and so is the carbonearrying tube C, which in thisquick move ment is practically connected `1)ositively.with the plungerl through the liquid D. This lifting ofthe carbon D establishes the are. The magnetism ofthe core or armature B attracts the armatures i at the adjustable pole-pieces and forces the clamping-platesj" against the tube C', but these clamps would not alone be sutlicient to hold the tube C in the quick up ward movement ofthe core or armature. As the-carbons are consumed and the resistance ot' the are increases, the magnetism of B is lessened to some extent, and the clampingplates have their pressure upon the tube U diminished by the weight ot' the armatures l. The tube C then drops, its movement being retarded by the resistance to the dow of the liquid around the plunger until the magnetism ot B is increased and the carbon-holding tube is again clamped. In this way a continuous feed of the upper carbon is maintained. lt' the arc is broken or increased to a definite extent beyond the normal resistance, the core or armature will drop, carrying the tube E and rod F and plunger G with it. The tube C will also be forced down positively by this movement through 'the liquid, the weight of the core or armature and attached parts and the force ot' the springsl beingadded to the Weight of the carbon-carrying tube.
Instead of supporting` the core and other parts by means ot' the springs K, the modiiied arrangement illustrated `in Fig. 3 may b e emy.
vforregulating this retarded independent ployed. Here an outer stationary tube, M, incioses the tube E. Such tube lll is supported on the top plate, b, of the solenoid or magnet. A spiral spring, L, attached to the top of tube M, is attached also to tube E, so that the latter is supported by said spring. This arrangement is equivalent to that before described. A suitable device, in, is employed to adjust the tension ofthe spring L.
What I claim isl.
