A simple form of waste press which can be readily frommaterial gererally at hand in a machine shop is shown in the ac-companying sketches. Only a few dimensions are given as thesizes will necessarily be varied tc suit different conditions. Apiece of wrought iron pipe to .x 12 in. in diameter and about 18or 20 in. in length is faced squarely at each end and drilled full ofsmall holes of about 4 ■• in diameter spaced about i in. cast iron plate i/^ in. thick is faced on top and a ring about 3in. wide is cut out as shown at A so that the pipe will fit down over. OI^ \V.\STE PHKSS. the projecting part D which holds the pipe central on the front of the plate is chipped out as indicated at C, the bollomsurface sloping dowmward towards the edge so thai the oil will runoff the plate. A piece of ^ in. or % in. steel plate is used for the top of thepress and this is cut about the same size as the cast iron plate atthe bottom. The two plates are held apart by four lyi in. pipesused as distance pieces, through which run bolts holding the platesfirmly in place. The steel plate is drilled lo receive a ironbushing, which is threaded to receive the screw and is heldin place by bolts 01 cap screws. The piston is made ofl-in. or i!4-in. cast iron, and secured to this is another cast ironpiece which is turned out lo receive the head of the screw. Thelatter is upset anil turned down lo fil.
