Abstract

24,270. King's Norton Metal Co., Bayliss, T. A., and Smith, H. M. Oct. 31. Primers.-The making, testing, and re-examination of electric primers or vent-sealing tubes are facilitated by the employment of a priming cup b fitting the interior of an ordinary service sealing tube a. A copper or other conducting pin c, contained within an insulating ebonite sleeve d, is electrically connected at one end to the cup b by a platinum wire bridge g, and at the other end by an insulated wire e to the metallic disk f, in the case of a " wireless " tube, or, in the case of an ordinary tube, with one of the electric conducting- wires, the other wire being connected to the base of the tube a. After the cup b has been charged with the priming-composition and tested or reexamined, it is inserted in the tube, where it is retained in position either by a screwed ring i or by a domed washer k, which is pressed flat to force the projections thereon into an annular recess in the tube.
