Vol. 87, No. 7. head, or support for the radius arm, is moved by an adjustingscrew underneath the bar which is held at the front of the slot-ter bed. The bar is graduated in half inches, and when beingset to any required radius, the sliding head is moved back tothe nearest graduation to give the required radius. The exactradius is then found by means of a tram, one point of which isplaced in the center of the sliding head and the other at thework. The exact distance and adjustments are made by asmaller adjustment screw at the end of the radius bar. Whenusing this attachment, the screw to the lower table of themachine is disconnected, allowing the table to be guided by theradius arm. S.\FETY VALVE TESTER. The arrangement shown in Fig. 20 was devised to quicklytest safety valves and thus save time over the old method ofwaiting until the boiler had developed sufficient pressure to
