The jig shown in Fig. 4 is used for splitting arch tube pross-ers. It consists of the mandrel A and the two blocks B and C,. Fig. 4—Jig for Splitting Arch Tube Prosse which are split as shown and act as guides to the saw used forcutting the prosser. The mandrel is made with a tapered sec- 661 662 RAILWAY AGE GAZETTE, MECHANICAL EDITION.

The guideblock B is placed on the large end, and C on the small end ofthe mandrel. Both are held by a set screw key which slides inthe keyways shown so that the slots will be in line with eachother. After the prosser has been placed on the mandrel, thesesplit guides are forced against the end of it by their correspond-ing nuts, gripping the prosser firmly between them. The workis done on a milling machine with a 3/32 in. saw. and the samejig can be used to make 2-in. prossers as well. FILTER FOR SHOP DRINKING WATER BY PAUL R.
