Abstract

1,001,637. Shovel excavators. MASSEY-FERGUSON Inc. Oct. 10, 1961 [Oct. 11, 1960], No. 36262/61. Heading E1F. Associated with the control valves 30, 35 of the boom-raising and scoop-tilting rams 21, 24 of a shovel excavator is a third valve 40 which is so actuated by the control lever of the boom-raising control valve 30 through a lost motion connection 51 that the third valve 40 can whilst the boom is being raised, direct hydraulic fluid from the exhaust sides of the boom-raising rams 21, 22 to the scoop-tilting rams 23, 24 to cause the scoop to be tilted forward as the boom is raised so that the scoop maintains a constant angular disposition with a reference plane to prevent spillage from the scoop.
