WE recently dealt with an engine-operated three-way tipping gear made by F. Walters and Co., Albert Street, Rugby, who have now devised a new type of sidetipping gear known as the Sideways model, which is intended for hand operation, and for which provisional protection has been obtained. As this will most probably be of particular interest to those of our readers who require a simple gear which is well protected from grit, can be easily mounted on most chassis and is sold at a moderate figure, we will describe it briefly.
As designed for ordinary operation from the side of the vehicle, the drive is first taken through a small pair of bevel pinions and thence by a third pinion of this type to the main bevel wheel which rotates' the tint of the tipping screw. Where, however, the overhang on the wagon is small, the power can he applied direct to the driving bevel pinion by a spindle having a bearing at the back of the chassis, thus simplifying the gear and cutting out one pair of bevel gears. The 30-cwt. gear sells at 116 5s,, whilst that for loads of 2-i-3-ton is priced at 121. These figures include the rocking brackets for the wagon body and cross-members for the chassis. • The nut is of gunmetal and is mounted on a ball-thrust bearing in a block carried by trunnions at each side. This allows it to rock freely sideways, whilst the driving bevel pinion takes its bearing on an extension of one of the trunnions.
A thrust block in a channel-steel cross-member and four rocking brackets are attached to the wagon body, bolts being , provided for clamping down while travelling, two of these
being removed at one side or the other, as required, for tipping purposes. These brackets hinge on four rocking bars carried on two cross-members which rest on the chassis, and are clamped down by U-bolts. The gear includes only six principal parts and, apart from the gears being covered over the top to protect them from dust and dirt, the screw is encased in a canvas cover with an oil receptacle at the bottom. Sideways tipping gears are also made to deal with loads of from 4 tons to 6 tons. These heavier patterns are arranged for engine operation.
