Abstract
1,157,487. Shovel excavators. WARNER & SWASEY CO. 25 Nov., 1966 [4 April, 1966], No. 27953/68. Divided out of 1,157,486. Heading E1F. To allow of variation of the speed-load lifting relationship of a boom of a materialhandling machine, e.g. a back hoe shovel excavator, the ram 93 controlling the vertical swinging of the boom 90 about a pivot 91 on the superstructure 92 of the machine acts on the boom through the pivot 97 of a linkage comprising a link 98 and a ram 102. The linkage, which is pivotally connected at 91 and 99 to the boom 90, permits of adjustment of the length of the lever arm between the pivot 91 and the line of thrust of ram 93 to allow of either low torque, large amplitude, fast movement or high torque, smaller amplitude, slower movement or intermediate variants, as desired, of the pivotal movement of the boom.
