Every tip-wagon driver, at solve time or other, has experienced considerable difficulty in manceuvring his machine into a position which would enable him to shoot the load. Contractors and owners, too, must frequently have noticed this difficulty, and have wished for something better in the way of tipping gear. Apart from the difficulty of manmuvring into a suitable position, the tipping of a load (especially if the point at which the tipping body is fuleriumned be aft of the mid position of the body) is a matter which calls for the exertion of considerable muscular effort, on account of the lack of balance in the body. Engine-operated tipping gears obviate the necessity for manual labour, but they may introduce parts which, without careful attention, are liable to derangement.
A wagon which may be tipped sideways appears to offer the best solution for these known difficulties. In the first place, such a wagon may be driven alongside the tipping ground without any manceuvring whatever, and, if the body be suitably mounted, one or two men can readily tip it. One of the most-practical of side-tipping bodies which we have seen for some time is that which is illustrated herewith. It is manufactured by Samuel Jackson, Ltd., of Smallwood, Sandbaeh, Cheshire, which maker has fitted several bodies of this type on to Forlen steam-wagon chassis. Some of these wagon bodies have been arranged so that the longitudinal sprocket shaft can easily be driven by worm gearing and a belt from the engine flywheel, or from a pulley attached thereto, but more often the tipping gear is hand operated.
A reference to the accompanying illustration will show that, at each end of the wagon, there is a vertical bracket, or frame, and that this frame carries a couple of guide pulleys for the tilting chains and a small chain sprocket, on the spindle of which sprocket a spur wheel is also mounted. This gear wheel may be driven from a hand-driven or power-operated longitudinal shaft through suitable reducing gear. As the gear wheels and chain sprockets are rotated in either direction, the lifting chains on one side are hauled in, while those on the other side are paid out, so that the hod y assuirow a position as shown in the right-hand figure of the two end views which are given herewith. A tipping body is just as necessary for a trailer as it is for a self-propelled wagon, and Samuel Jackson, Ltd., is oinking large numbers of side-tipping trailers to suit the requirements of brickmakers, builders, colliery owners and contractors, as well as for a variety of other businesses which call for the transportation of heavy loose material in bulk.
