Abstract: 16,941. Codd, L. B. Aug. 23. Arc lamps. - A brake regulating mechanism. Fig. 1. contains a brake chain or the like f, attached at its ends to a regulating-lever h, at opposite sides of the fulcrum l, and passed round a wheel c, which is geared to the carbons, the upper carbon-holder d being weighted ; the lever h carries cores in series and shunt solenoids a, b, or is otherwise electromagnetically operated, and it also carries means for deflecting and thus tightening the brake chain as it turns under the action of the series solenoid a, several modifications of such means being specified. In the construction shown in Fig. 1, the ends of the chain are secured at the middle point of two differentlycurved surfaces m, n on the lever h, the curves being such that, when the left-hand end of the lever h is raised, the chain is tightened by the increasing distance of the operative part of the surface m from the fulcrum l, this effect being reduced to some extent by the surface n. The curves may be such as to cause either gradual or quick application of the brake, and the surface n may be made with upwardly-increasing radius, to add to the effect of the surface m. One curved surface may be dispensed with. The rigid surfaces may be replaced bv similarly-curved springs, or by springs adapted to act on the outside of the chain, both forms being shown in Fig. 5. Or the surfaces may be replaced by pins or rollers fixed on the lever to act inside or outside of the chain, as shown in Fig. 15, or by weighted arms of various forms pivoted on the lever, and optionally adapted to rest thereon when the brake is free, Figs. 8 and 13 showing two forms.
