FEEDING AND REGULATING MECHANISM FOR ARC-LAMPS.

SPECIFIGATION forming part Of Letters Patent NO. 677,005, dated June 25, 1901.

Application filedlebruary 6, 19 01- Seria1No.46,Z44- (Ndmorleh) To all whmn it may concern:

Be it known that I, WILLIAM E."/VALDRON, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented new and useful Improvements in" Feeding and Regulating Mechanism for Arc-Lamps, of which conductor.

the following is a specification.

This invention relates to certain new and useful improvements in are-lights, the purpose being to provide an arc-lamp .or headlight for electric cars or in other such places where the lamp is subjected to jars and to intermissions in the flow of the current such as are incident when a car passes a crossing or over a rough joint, the construction being designed to provide a lamp with a rigid frame and means wherebythe arc will be instanta-,

elevation; and .Fig. .3 is [afront elevation of.

feed being accomplish'edby gravity.

My'invention consists in the construction and organization of the parts, as will be hereinafter set forth, and specifically pointed out intheclaims. I

In the accompanying drawings, Figure 1 is a front elevation of -anarc-lampconstructed Fig; 2 is a side the upper portion of a'lamp, showinga modification. i i V v To the main frame or back-piece A is bolted or otherwise attached the lower carbon holder A, said holder I being provided with means whereby the lower carbon H can be adj usted to the desired height, the lower-carbon holder A vprojecting from the back-piece, as shown.

To the upper portion of the main frameis secured a frame B, it being separated from the back-plate by suitable insulations a, and

this frame B is shaped to provide a laterallythe part B, and through these guides pass the v I upper-carbon carrier L, towhich the upper carbon is secured by means of a clamp F. The carbon-carrier is adapted to move freely through the guides E E, and in order to insure electric connection between the wire or coil of the electromagnet and the carbon-carrier a wire cis attached to both of the guides and'to. the clamp F, the wire adjacent to the clamp being bent spirally to form a coil D, which permits the upper-carbon carrier moving vertically. To the vertical portion 1) of the frame Bis pivoted the armature, comprising abar'J, which carries a metaliplate I, located above the core of the magnet. The I bar J may be made of non-conducting mate- 8o rial and has at itsend nearest the carbon an aperture through which passes the shank of a movable coupling m, the rod from which the coupling is made being threaded to receive a nut which contacts with the bar J, 5 the opposite end of the bar being formed -into a ring which engages an eye or perforation through the ring-clutch K. The nut and threaded shank of the coupling provides means for adjusting the armature to suit the 0 conditions under which the lamp is used.

The ring-clutch K encircles the carbon holder L, being placed betweentheguides therefor, so that it may bear upon the lower guide E. The ring-clutch is maintained normally in a horizontal position, so that the carbon-holder can slide freely therethrough by springs, and, as shown in Fig. 3, a single spring m encircles the carbon-holder and bears againstthe ring-clutch and the upper- 10o carbon guide, or I may attach a spring 70 to the bar J and to the stud which projects from in a horizontal position.

the vertical portion 1) of the frame B, and on the other side there is a spring 70, oneend being attached to the ring-clutch and the other end to the frame, The different arrangement of springs I consider equivalents, as they both serve to move the armature away from the magnet and tend to hold the ring-clutch It will be noted that when the ring-clutch is horizontal the upper carbon will be fed downward, by gravity; also, that when said. clutch is horizontal the armature is 'out of contact with the core of the magnet I In practice the end of thewire from the coil of the electromagnet may be formed into a coil and attached directly to the clamp F, the other end of the core being fastened to a binding-post, a wire leading therefromtoa resistcurrent passes through the coils of the electromagnet, energizes the soft-iron core thereof,

and draws the armature down, tilting the clutch-ring, which responds to the movement of the armature'and strikes the arc, insuring the proper working of' the lamp, and as the carbon burns away the circuit is broken, which permits the carbonto move downward sufficiently to reestablish the arc. Thisac- I tion takes place instantaneously. Under all conditions the carbonsare held in the same relative position by the electromagnet, so that under all variations inthe current the lamp gives a steady even light'and is.not eXtinguished until the circuit is entirely broken. Thus the lamp operates under extreme variations of the current and is not affected by jar or vibrations, such as are present on electric cars. Two or'more lamps may be placed in series or may be used independently, and all shunt-circuits are avoided. I I v I When necessary or deemed advisable, the electromagn'et, as described, may be inverted, thusplacing the armature under the magnet, reserving the same general construction.

' Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is I I 1. In an arc-lamp, the combination of a main supporting-frame, a lower-carbon holder in electrical connection therewith, a frame attached to the upper part of the main supporting-frame and insulated therefrom said upper frame having guides for the upper carbon and a projecting portion, anelectric magnet v and its armature the armature being carried by the projecting portion of the frame, a ringclutch mounted between the guides, means as a spring or springs for holding the ring-clutch horizontally upon one of the carbon-guides and the armatureaway from the coreof the electromagnet, substantially as shown.

2. In an arc-lamp, the combination of a main supporting-frame and a lower-carbon holder which is rigidly attached thereto, of a frame having guides for the upper carbon, a laterallyprojecting portion constructed to an electromagnet and an armature therefor,
