ELECTRIC-ARC LAMP.
SPECIFICATION orming part'of Letters Patent No. 360,662,dated April 5, 1887.
Application filed l\l arch 9, 1896. Serial No. 194,584. (No model.) Patented in England July 2, 1885, No. 8,019 and September 19, 1G85,No.1l,l75.
To all whom it may concern.-
Beit known that I, CHARLES FREDERICK COOKE, a subject of the Queen of Great Britain and Ireland, and residing at Buckingham Works, York, in the county of York, England,
have invented certain Improvements iu Electric-Are Lamps, (for which British Letters Patent No. 8,049, dated July 2, 1885, and No. 11,175, dated September 19, 1885, have been obtained,) of which the following is a speciiication.
My invention consists of certain improvements in 'the construction of regulating mechanism for electric-arc lamps, as fully described hereinafter.
In the accompanying drawings, Figure 1 is a side view, partly in section, of sufiici'ent of an electric-arc lamp to illustrate my invention. Fig. 2 is an elevation of part of the same, drawn to an enlarged scale and part of the mechanism being removed for the sake of simplicity. Fig. 8 is an elevation corresponding to Fig. 2, but taken at right angles thereto. Fig. 4 is a sectional plan View illustrating the arc-striking devices, (not shown in Figs. 2 and 3;) and Fig. 5 is a side View of the devices shown inFig. 4. F F is the frame ofthe lamp, which carries the arc-regulating mechanism, and which consists of plates connected by pillars, and on top of this frame-work F is a plate, f, preferably of wood or other insulating material, Which carries the bindingposts as x for the line-wires'. The lamp illustrated in the drawings is a twin lamp, in which two sets of carbons are used, but as the two sets of regulating devices for the two sets of carbons are alike in their construction and operation, a description of one will suffice for both.
S is one of the solenoid-coils of the regulating mechanism, and which is wrapped with coarse wire in the main circuit.
`R is the rack or rod which carries the upper movable carbon, and which is suitably guided in the frame. This rack, as shown more fully in Figs. 4 and 5, gears into a pinion, p, mounted on, but not keyed to, aspindle, Q, carried between centers p p on a rocking frame, L. This rocking frameis pivoted at d to the framework,F of the lamp, and is connected at one end by a rod, s, with the core s2 of the solenoid S, while at the opposite end it is counterloalauced by a weight, L2.
A ratchet e wheel, l', is formed in one part with or secured to the pinion p, and with this ratchet-wheel engages a spring-pawl, wi, carriedby a spur-wheel, w', which is secured to the spindle Q, so that the carbon-carrying rod s cannot descend without turning the spun wheel w', as well as the pinion p; but the pinion p can revolve iu the opposite direction without turning the spur-wheel w. The latter gearsinto apinion, p2, on a spindle, p3, mounted on centers p5 on the frame F, and on the same spindle is secured a spur-wheel, p, which, as illustrated in Fig. 1, gears into a pinion, w, on the spindle which carries the brake-wheel W'. In connection with this brakewheel I make use of a brake, B, Figs. 1, 2, and 3, car-- ried on the arm of a spindle, P, mounted in suitable bearings in the frame. On this spindle is mounted loosely an armature, T, the up` per end of which extends alongside the solenoid to its upper pole, and on the other side of this armature, at its outer end, is the pole of a fine-wire magnet, M, in the shunt-circuit, so that this armature can have a limited vibrating motion between the poles ofthe two magnets.
To the spindle P is secured an arm, C, which is connected to the armature T by means of an adjustingiscrew, Sc, passing through alug, A, on the armature and into a corresponding lug on the arm C, there being an intervening spring, Sp, between the two, Fig. 2.
An adjustable set-screw, St, in the arm C is adapted to come into Contact with a stop, F', on the frame when pulled over by the counter-weight C' on the armature-spindle P or by any other suitable retractor.
The main circuit from the binding-post a is through a conductor, 1, to the coil S, thence to the frame F, rod It, upper carbon, lower carbon, and then through a central post, K, of the frame, Fig. 1 plates k 7e', which are insulated from the portion F oi' the frame, and conductor 3 to the exit binding-post fr. The shunt-circuit is from the binding-post x, conductor 4, coil M, and conductor 5 to the exit binding-post fr.
IOC)
The ne-wire magnet M may, as illustrated in Fig. 2, serve for both sets of regulating de vices. In the drawingsl have not illustrated the mechanism for transferring the creuitfrom one/set of carbon regulating devices to the other when the upper carbon of the first set is burned out, as that forms no essential part of my present invention.
The operation of the regulating devices described is as follows: When the lamp is thrown into circuit the core of the solenoid is raised, and this raises with it the lever-f rame L, the pivot-pins ofthe latter being out of line with the center of the axis Q. The elevation of the lever will cause the carbon rod R and upper carbon to be raised, because the Wheel-work cannot rotate, since the brake B is held on the brake-wheel by the attraction of the armature T toward the pole of the solenoidcoil S. As the carbon points burn away and the length of the arc increases, the consequent increased resistance in the working-circuit will cause a decrease of current passing through the coils ofthe solenoid S and an increase of current through the shunt-circuit and coil of the armature magnet M until the magnetism of the poles of the two electro-magnets is about balanced, when the counter-weight C of the armature T will pull the armature away from the pole of the solenoid S toward the pole of the armature-magnet M and raise the brake B off the wheel NV. The carbon rod lt will then (lescend, since the wheels are free to turn, until,
by the approach ofthe carbon points, the excess of current in the solenoid S and main circuit is increased, to cause the attraction of the armature T and the application of the brake B to the wheel W', to arrest the descent of the carbon rod at the proper point.
It will be seen that the same electromagnet or solenoid in the main circuit which serves to form the are also serves to control the brakelever, the latter lying substantially parallel with the said electro-magnet.
I claim as my invention- The combination of a rack carrying the movable carbon of an electricarc lamp, a pivoted lever carrying a pinion geared to the rack, and an electro-magnet in the working-circuit controlling the said lever with an electro-magnet in a shunt, an armature-lever vibrating vbetween the poles of the two magnets, a brake carried by the arn'iaturelcver, and a brakewheel mounted on the iixed frame of the lamp and geared tothe said pinion, all substantially as set forth.
In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
CHARLES FREDERICK COOKE.
