An Exhibition of Tools and Implements Designed to Improve the Efficiency and Economy of the Fleet Owner's Garage

THIS year's exhibit of garage equipment may be said for the first time to embody appliances which are really specially designed for use in heavy-vehicle garages, Hitherto manufacturers of equipment have, with one or two exceptions, been content to make the needs of garages which cater only for private cars their first consideration. The equipment they have offered to the commercial-vehicle user and manufacturer has sometimes been of the nature of makeshift.

There is now to be noted a considerable change in that attitude. On the majority of stands can be seen new items of equipment which are obviously specially adapted to the needs of commercial-vehicle owners and capable of being need with efficiency and satisfaction in connection with the heaviest of vehicles.

In the following brief forecast of the exhibits these items are specially indicated. Readers should realize that the exhibitors comprise manufacturers of equipment, as well as factors and concessionnaires, so that it is often the case that the same make of appliance is shown on many stands. In order to avoid needless repetition, attention has been directed 'where possible to those exhibits which are peculiar to the stand which is being considered.

AR,REL MANUFACTURING CO., LTD. 417 THE universal jobber, which is to be the principal exhibit . on this stand, comprises a small hand geared rotor with or without a long flexible shaft. The machine is supplied for bolting or clamping to the bench. It can be used for grinding, drilling, burnishing, milling and filing, and, with the flexible shaft, for removing carbon and for a variety of other purposes. The well-known Arrel universal spanner will also be shown.-26, Charles Street, Hatton Garden, London, E.C.1.

E. P. BARRUS, LTD. 385 HERE will be staged electrically driven tools of all descriptions, as well as a series of Blackhawk hydraulic jacks, Armstrong wrenches and machine tools, and a tool chest. The electrically driven tools include the Van Norman cylinder-boring bar, piston-turning and grinding machine. valve ref acer and reseater, and standard engine kit. There will also be shown Stanley electric hammers and screwdrivers, decarbonizing tools and a complete series of pliers, punches and wrenches.-35-37, Upper Thames Street, London, E.C.4.

B.E.N. PATENTS, LTD. 407 EXHIBITS on this stand will include high-pressure washers, air-compressor units, spray-painting plant, flexible shaft gear for use in flatting and polishing cellulose lacquers, for paint and rust removing, grinding and drilling, sheet-metal sanding, glass edging and polishing, as well as a variety of other purposes. There will also be shown an automatic tyre inflator, adjustable axle stands, hydraulic and ratchet jacks, and a new line of petrol engines from h.p. to 2i. h.p. for driving air compressors, electric generators, pumps and so on.

The Skilsaw sander will, perhaps, be the most novel item. It is a portable electric sanding machine comprising a small electric motor driving a band of sand paper mounted on a belt.-92, Tottenham Court Road, London, W.1.

BENDIX-PERROT BRAKES, LTD. 401 THE Bendix-CoWdrey brake tester is designed to give immediate indication of all the essential factors relating to brake effort on the vehicle to which it is applied. It shows maximum brake power available and the distribution of the braking effort between the front and rear wheels. The adjustment of the brakes can be equalized, as regards the two wheels of any axle, while the machine is running. It is possible to estimate the stopping distance at any particular road speed.—King's Road, Tyseley, Birmingham.

Besides a range of air compressors, portable, semi-portable and stationary, there are also paint-spraying plant and a new design of air and water tower. A new introduction is a series of small, heavy-duty air compressors designed for long and continuous running, with a view to their carrying out such duty as paint spraying.—Causeway Works, Fishponds, Bristol.

BRITISH OIL CLEANERS, LTD. 432 HERE will be staged apparatus which appears definitely to have solved the problem of utilizing discarded lubricating oil. In its operation it is claimed that it is not merely a filter, but is definitely a cleaner. This is accomplished at a cost of less than id. per gallon.

The apparatus is electrically operated, and to use it water and dirty oil are poured into the cleaning tank, together with a material known as Foxite.. The current is then switched on, and the cleaning process commences and proceeds until completed, when it automatically ceases and the current supply is cut off. The foreign matter is drained away from one tap and the purified oil taken away by another. The cost of cleaning 10 gallons of oil with this apparatus, assuming current at id. per unit, is only 7d.--66, Upper Richmond Road, Putney, London, S.W.15.

THE BRITISH OXYGEN CO., LTD 38/3

a

A NEW development in tyre inflation is to be introduced

in this company's exhibit, in the form of cylinders of compressed nitrogen, which gas is now recommended for that purpose.

DUNLOP RUBBER CO., LTD. 399

THE outstanding items shown herei,will be the portable ,,air compressors and jacks. Of the latter, the new hydraulic jack, capable of lifting three tons, is perhaps the most important feature. It conforms with the requirements of the Road Traffic Act. All the operating mechanism is inside the jack and is easily worked. The height when closed is 8 ins., and when totally extended 17i ins. The actual lift is 5i ins., but if the jack be placed some distance from the wheel, say, under a spring, the opposite wheel will serve as the fulcrum and enable a lift of at least 6 ins, to be effected, thus meeting Ministerial requirements.—Fort Dunlop, Birmingham.

EAST LONDON RUBBER CO. . ...... 404

THIS company's exhibit will embody almost all the principal items of garage equipment in a wide variety of makes. Prominent amongst the exhibits are HP breakdown and salvage equipment, as well as EIF jacks of various sizes.

DEFINITELY the most interesting exhibit will be the new M.E. Roloid rotor washer. This high-pressure washing plant incorporates a new design of pump, which has cog

wheels of special design and includes an arrangement whereby a vacuum is created around the pump bearings so soon as the pump begins to work, thus ensuring absence of water from the bearings.

The commercial-engine stand has the special advantage that the level of the stand can easily be adjusted. It is strong enough to support the heaviest of units, including compression-ignition engines, whilst the engine, when in place, can be rotated and held in any position. Other equipment will include breakdown gear, cleansing tanks, air compressors and small tools.-5, Prince of Wales Road, Norwich, HENRY MILLER AND CO. 400

AN impressive exhibit on this stand will be the Skyhi 7-ton

lift, 22 ft. long in the tracks, carrying a Leyland chassis. Another interesting and novel exhibit will be the Skyhi hydraulic jack, which incorporates two pumps. When bringing the crutch of the jack up to its work both pumps are in operation, and each stroke of the handle effects a lift of 5 ins. When the crutch takes hold and the weight is encountered one pump ceases to operate, thus multiplying the mechanical advantage available and increasing the weight capacity. The lift is 2 ft. 5 ins, and the lowest position of the crutch 6 ins.-186, Weimer Road, London, W.11.
