At thelower end a ring is screwed upon the pipe, to which the lowerhead, with the stuffing-boxes, is bolted. The piston is the ordi-nary cast-iron head, with a follower holding a cup packing inposition. The piston rod is 1 in. in diameter, and is attachedto the yoke of the hook by a nut held in position by a splitkey. The arrangement of the piping is clearly shown. Thepipe making connections between the top and bottom pressof the cylinder is 4-in. gas pipe. Our other engraving, the valve used for operating the hoist, gives a very clearidea of its design. It is shown in cross and vertical sections,and the valve is attached at. the lower end of the vertical pipe,as shown by the eugraving. The valve is a self packing.
