Show Simple Way to Mount Your Spider-Web Coil For those nslng, or contemplating the use of spider-web coils, the follow. Ing will be found an extremely simple and efficient means ot mounting them on a panel, and novel aa to the method meth-od employed In providing the necessary neces-sary variation of coupling. The center or secondary coll ts mounted perpendicular to the rear ot the panel and ts stationary. The primary pri-mary and tickler colls are attached to Splder-Web Coil Mounting. the panel by means of small binges. The springs K and K-l tend to hold the coll 8 out against the cams P and which are made of fiber or hard rubber sheet Nuts Z and Z-l provide the necessary pressure adjustment against springs T and Y-l. which cause sufficient friction to keep the cams from moving of their own accord. The rapidity and extent of variation of the primary and tickler colls deiend on the curvature of the two cams. Thus, cams may be mude for rapid or slow adjustment, or a combination, to meet the requirements of the circuit. Tills method ot mounting has the added advantage of practically eliminating elimi-nating disagreeable capacity effect |
