IN the rAsumet of patent specifications in the issue of The Commercial Motor for April 21st we dealt with the claims of Mr. H. 0. Williams, of 407, Anlaby Road, Hull, for a useful apparatus for handling vehicles under repair or overhaul.
This ingenious hoist is marked by simplicity and will lift the end of a van or lorry under repair to a height convenient at which to work, and will also rim it anywhere with ease, thus obviating the pit and the flat-on-youe-back position. It is a, tubular structure of inverted U shape spread out at the base for stability and running on castors, which are so fitted as to give free and easy movement when a load is in suspension. The top half is telescopic with the bottom half, which fact enables the frame to be raised or lowered as necessary and means a simple dissembling of the hoist without a spanner for convey
ing to a roadside repair. • • The load is lifted by wire cable running from the drum on the lower half of the frame over pulleys to thetop frame, from which it can suspend front both ends, or singly from the middle. The gears for the drum are of the wormdrive type, having considerable leverage for raising the loads, which will not B24
allow them to lower when the handle operating the gears is released. In size the hoist is particularly adaptable to general requirements entirely by its own power; It can be raised to 9 ft., which means that it can bridge any van at either end and is of ample width ; whilst at its lowest height it will carry its load through the average doorway.
By its double suspension a complete body could be lifted off a chassis and the single suspension would be admirable for taking the engine out.
For general heavy lifting and transporting of loads short distances, such as at railway stations and warehouses, it would save labour, time and cause troublesome loads to be manipulated quickly and easily. It takes up little room, is easily wheeled or taken to pieces and erected by one man, has no costly parts likely to break down, and requires no skilled attention in use. By simply increasing the gauge and diameter of the tubes, it could be made for heavier work without any further mechanical contrivance. The gears and cabling could be taken down and used apart from its frame, and so left in all odd corners, where even the frame could not reach. All that this entails is the taking down of two bolts.. The gears could be fastened to any girders and the wire cable suspended where. required.
The hoist shown in the illustration could lift anything up to 25 cwt, and be manufactured at an attractive figure. There are only 10 parts, including such details as pins, comprising the complete device. Its inventor is open to negotiations with anyone seriously interested.
