588,148. Portable conveyers. WOLSELEY SHEEP SHEARING MACHINE CO., Ltd., and MACNAMARA, H. J. Oct. 30, 1944, No. 21103. [Class 78(i)] [Also in Group XXXII] In an elevator or loader of the type which comprises a sloping platform up which travel transverse slats secured to endless chains passing over wheels at the upper and, lower ends of the platform and in which such wheels are driven by a motor mounted on the chassis on which the track is carried, the chassis is mounted on a pair of main wheels at one end and a small roller at its other end, the whole unit being towable by another vehicle. As shown in Fig. 1, the chassis A is mounted on wheels B at its forward end.and on a roller C at its rear end. The roller C, Figs. 3 and 4, is, carried by two adjustable brackets D which are connected to the chassis A by means of a pivot bolt a. Each bracket has three holes d, any one of which may be selected, when clamping the bracket D to the frame A by means of a bolt a<1> to enable adjustment of the height of the chassis in relation to the ground. The construction is such that most of the load is taken by the wheels B. The platform E comprises a metal floor e with walls e<1>. At the upper and lower ends are mounted chain wheels g<2>, g, respectively, which engage endless chains g<1> to which are attached transverse slats H. The chainsare driven through the wheels g by a petrol motor M via a gearbox N. The wheels g carry between them a roller g<5>, Fig. 4, to prevent the operator's foot from getting between the slats H and the bottom edge of the floor e. The platform angle is adjustable by chains K each attached at one end to a frame J, passing under a pulley e<3> mounted on the platform, over a pulley at the frame top and thence to a winch j' fitted with a handle j<2>. The elevator may be towed from either of its ends by a frame P, (see Group XXXII) which when attached to the front allows pivoted movement between the chassis and tow bar such that the rear roller may ride over bumpy ground. When towed from the rear, the connection is made rigidly so that the rear is lifted clear of the ground, the elevator then riding on its main wheels only.
