This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1917 edition. Excerpt: ...clear, the fuse is screwed home with the spanner D and locked to the notches in the shell with a punch and hammer. In case no night tracer is to be used on the shell, lead plugs are pounded into the spanner holes, and a sheet-metal cover E is put over the end with the edges in the cover groove. A calking lead ring F is then pounded into the groove as indicated in Fig. 109. Where a night tracer is used, the fuse is put in in the same way, the lead slugs are pounded in, the special cover put on and a lead ring put in place. This ring, however, is not pounded in as previously described, but is pressed in as shown in Fig. 101, the process being graphically shown in Figs. 112-A and 112-B. Screwing in of the night tracer consists in placing the tracer in a vise and screwing the shell onto it by hand. Making The Band Operations on making the copper band are as follows: 1. Cut from tubing 2. Anneal 3. Pickle 4. Wash 6. Planish The list of operations is almost self-explanatory; the details, however, are given under the proper headings. The last operation, planishing, is really a sizing for width, as the band is pressed between two flat dies, as shown in Fig. 102. Making Night Tracer 1. Drilling, counterboring, tapping 2. Facing end and threading. Night tracers are made from brass rod in automatic screw machines; the order of procedure is as given above and is the usual standard screw-machine practice in every way. Facing and threading of the closed end is done in a hand screw machine. Making Night-tracer Disks 1. Punching inner disk 2. Punching outer disk 3. Turning ignition tubes 4. Milling ignition tubes 6. Assembling ignition tube to outer disk The making of the disks is a punch-press job, as shown by the punches and dies, Figs. 135, 136, 138...show more
