HANS OTTO SVVOBODA, OF NE YORK, N. Y., ASSIGNOR TO THE GENERAL IN CANDESGENT ARC LIGHT COMPANY, OF SAME PLACE.
ELECTRIC-ARC LAM P.
$PECIFICATION forming part of Letters Patent No. 534,677, dated February 26, 1895.
Application filed April 6, 18 94. Serial No. 506,599. (No model.)
To all whom it may concern:
Be it known that I, HANS OTTO SWoBoDA, of New York, in the county and State of New York, have invented a certain new and useful ImprovementinElectric-ArcLamps, of which the following is a specification.
The object of my improvement is to produce a simple and efficient cut-out for an arc lamp, and it is particularly applicable to a differential lamp.
I will describe a cut-out embodying myimprovement, and then point out the novel features in the claims.
In the accompanying drawings, Figure 1 is a side view of a portion of a lamp embodying myimprovement. Fig. 2 is another side view of the same, but this view is taken at right angles to the former. Fig. 3 is a diagrammatic view illustrating the winding of the magnets and the circuit, so far as necessary to an understanding of my improvement. Fig. 4: is a diagrammatic View illustrating a modification.
Similar letters of reference designate corresponding parts in all the figures.
A designates a support for the upper carbon of the lamp. It may be of any construction, although in the present instance it is shown as made in the form of a rod provided with a toothed rack.
B designates mechanism for controlling the descent of the carbon support. It comprises a magnet armature O.
O, G designate magnet spools for governing the mechanism B. Each of the magnet spools C, G has a series winding 0, which in the present instance happens to be the inside winding, and a shunt winding 0 To avoid any misunderstanding, I will add that the so-calied series winding is in series with the arc of the lamp, and that the shunt winding is a shunt circuit around the arc. These windings are to act in opposition, and, hence, must either be reversely wound, or, if similarly wound, must be connected so as to oppose each other.
The connections between the windings of the two spools maybe made in the way which is usual in connecting two spools of an ordinary horse-shoe magnet, or in other words, the series windings of the two spools may be connected in series, and the shunt windings may be connected in series Of course the connections may be made in parallel if desired.
The armature O is pulled up by the spools when they are sufficiently magnetized, said armature being acted upon by pole pieces 0 which extend below the spools C, 0
D designates a lever, which is here shown as fulcrumed between its ends d, d and overbalanced at the end 61 The end (1 is shown as extending upwardly toward the bottom of the spool 0 The lever D is made as a permanent magnet.
When the pole piece 0 of the spool O is sufficiently magnetized by current, passing through the series winding, to attract the lever D, the latter will rock toward said pole piece and thus will be brought into contact with a contact piece E, which is here shown as made in the form of a screw titted to a metal block 6, which is fastened to and insulated from the frame of the lamp. This block 6 is connected by a wire 6 with the shunt coil or winding of the spool C Then the lamp is started and always while it is burning, the lever D will be attracted by the pole piece 0 of the spool C in the manner described, but whenever thelamp goes out or its arc becomes too much elongated, the magnetism of the said pole piece will change its polarity so that the lever will be released. The release of the lever will break the shunt circuit and protect thelatter, besides avoiding a waste of current.
Obviously, instead of over-balancing the lever D, a spring might be employed to oppose the action of the pole piece 0 of the spool 0 The lever D instead of being a permanent magnet may be an electromagnet by making it of soft iron and surrounding it by a winding placed either in series or in shunt with the arc of the lamp, as illustrated by Fig. 4.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. In an arc lamp, the combination of a magnet for controlling the carbon support of said lamp, a main circuit and a derived circuit winding surrounding the magnet, a movable piece in the form of an armature in circuit with one of the windings, independent from and adapted to be moved toward and away from the pole piece of the controlling magnet, and a contact piece coacting with the movable magnet piece, substantially as specified,
2. In an arclamp, the combination of a magnet for controlling the carbon support of said lamp, windings or coils for energizing the magnet, and a movable piece consisting of an armature independent from and actuated by the pole piece or pieces of the carbon support controlling magnet to make or break the circuits of one of said windings or coils, substantially as specified.
In an arc lamp, the combination of a magnet for controlling the carbon support of said lamp, windings or coils surrounding said magnot, a movable piece consisting of a polarized armature independent from and actuated by the pole piece or pieces of the carbon support controlling magnet to make or break the circuit of one of said windings or coils, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
HANS OTTO SWOBODA.
