A shield or hood 66, that may be made integral with the lower bearing bracket 38 for vthe shaft 35, incloses the lower crank 58 to prevent the crank from striking-a person standin near the machine during the outward t row or swing of the crank. The legs 32 of the tub may be held together by tension rods 68, each extending between opposite legs and the rods crossing each other at the intersectionof the cross members 31. Thesaid rods extend at their ends through the legs and are screw-threaded to receive nuts 69 by which the rods are placed under tension and the tub legs held firmly against the ends of the cross members to give the required'rigidity to the connection between the cross members and legs. The said cross members may be attached to the legs -by screws "Z0 (Fig. 3) that extend through the legs and into the ends of the crossmembers.

member is formed with a hook that engages over the pivotpin-73, and is provided with a spring-pressed latch bolt 76 that occupies a recess in said inner swinging member and is normally forced, by a spring 77, ar-

"ranged behind said recess and bearing against the end. of the latch bolt, with its outer end beneath the pivot pin 73 so as to prevent the outer end of said inner member of the jointed pitman from-rising. The latch bolt jis retracted, against the action of said spring 77, to free it from said pivotpinby means of a pin 7 8 extending outwardly-therefrom through a slot 79- in the hook end of said inner pivoted end of the pitman. Said pin also serves by contact with the outer end of the slot, to limit the outward movement of the latch bolt.
