Plate 23.—Authors Interrupters for large Static Machines. Slip the metal collar of oneInterrupter over the vulcanite handle of the Static sliding pole and fix it in place with set-screw as shown in upper illustration. The spark-gap between the balls is here open. Toclose the gap and use a continuous current make a half turn of the handle till the ballsmeet as shown in the lower figure. To increase the spark-gap more than a turn pull the han-dle of the interrupter through its sleeve and away from the prime conductor. To clean andpolish the brass parts take the interrupters apart as shown in the upper figure. The smallerpair shows right and left positions of the interrupters when on the opposite poles. The model pictured in my original volume early in 1897 is here greatly improved newer insulating handles are nine inches long and protect the operator from sparks whenregulating the powerful current. The long handle to the set-screw is a convenience. It is ofprime importance to
