Abstract
7429. Waterhouse, L. M., and Simplex Steel Conduit Co. March 29. Conduits.-Relates to metallic conduits, particularly the "Simplex" conduit, for electric-light cables and the like. To maintain a complete metallic circuit, an externally-screwed bushing 1, slightly tapered and provided with a nut 2, is split as indicated in Fig. 4. The coupling, bend, &c., or the nipple of the fitting to be attached to the conduit 5, has an internal screw-thread 7 adapted to engage with the screw-thread on the bushing, the slight tapering of the bushing bringing about a firm pressure, and consequently a good metallic contact, between the adjacent surfaces of the bushing and conduit. This pressure may be increased by coning the part 13 of the bushing between the nut 2 and the screwed part 1. The screwed part of the coupling &c. may be tapered in addition to, or instead of, tapering the corresponding part of the bushing. To prevent the ends of the conduit or bushing from abrading the cable, the bushing and coupling &c. are provided with shoulders 8, 10, Fig. 5, or the end 12 of the conduit may be reamered off as shown in Fig. 1.
