11,282. Grote, E. R. May 12. Arc lamps; arc-lamp electrodes.-Electrodes are formed by hollow cylinders a of length not greater than twice their diameter, and contain flame cores surrounded by carbon zones of uniform thickness as described in Specification 23,429/07. The electrodes may be mounted on inclined spindles c, which are geared together through an idler g and driven intermittently by an electric motor so thai the cores are brought into use successively. One of the spindles is carried by a frame h mounted coaxially with the idler, and is moved laterally by a bent lever and solenoids to strike the arc.
