Abstract

626,459. Automatic catches. SANFORD INVESTMENT CO. April 25, 1946, No. 12547. Convention date, April 16, 1945. [Class 44] [Also in Group XXXII] A latch 15 on a lateral shaft 16 at the rear of a dumping wagon (see Group XXXII) is spring pressed to a position in which it supports a drop bottom door 10 by means of a member 14 which engages a concave surface 19 on the latch. The line of action of the force at the point of contact is directed to hold the latch engaged. As the wagon moves forwardly (to the left in Fig. 3) a member 33 upstanding from the track engages the latch 15 on its forwardly and downwardly directed surface automatically to disengage it. A bar 20 projecting from the latch through a slot 21 at the rear of the vehicle permits manual disengagement of the latch.
