COMING so close as it does after the Earls Court Motor Show, the Scottish Show must contain little in the way of accessories and garage equipment that could be classified as new. From the visitors' point of view this is not necessarily of any importance or relevance, as Glasgow is far enough away from London that few people will spend time at both Shows. But it means that almost all the important items which should have a place in a review of this type have recently been dealt with —in the review of Motor Show Accessories and Equipment in The Commercial Motor of October 18.
Another difficulty in compiling a review is that many manufacturers don't appear to know exactly what they are going to show at Glasgow until the last minute. No doubt they concentrate on the Earls Court Show and only turn their minds to Glasgow when this is over. It may be, therefore, that there will be some interesting items at the Show other than those mentioned. If there are, any details w:ll be included in next week's issue.
Although many of the exhibits will be the same as those at Earls Court, there will be many which have only commercial vehicle application which were not shown there.
Some concerns managed to get away with showing a few commercial vehicle items at the Motor Show, but others, such as C.A.V. Ltd., whose main activity is in the commercial vehicle field, are checked closely and can get away with nothing. C.A.V. is, in fact, introducing a number of important items at Kelvin Hall. Being shown for the first time in public are the L723 flush-mounted rear lamp for passenger vehicles, the 398 transistorized automatic-dear-change control, the 409 transistorized invertor for fluorescent lighting, the 415 transistorized shaver suppls unit and the PPE pressurizing fuel transfer pump.
The interesting thing about these accessories is the use of transistors. The 398 control unit for C.A.V. automaticgear-change equipment is a transistorized version of relay-operated equipment which has been in use for some years. Printed circuits are used to replace conventional wiring and the function of the control unit is to determine the correct gear by sensing road speed and engine torque, producing an integrated signal which is used to operate an epicyclic gearbox.
The new unit is very much smaller and lighter than the original. Both the 409 fluorescent lighting and the 415 electric
shaver supply units use a transistor invertor circuit followed by a transformer to produce ac. mains voltage from a vehicle's d.c. system. The PPE fuel pump is designed for use with multi-fuel engines where higher pressures than normal are required, and consists of a 24 V electric motor driving the fuel transfer pump from the DPA injection pump. It can deliver fuel at the rate of 30 gal. per hour at 25 psi. and when' installed is immersed in the fuel, the motor remaining outside the tank. The L723 rear lamp combines in one neat unit a rear lamp. stop lamp, flasher lamp and reflector.
In a similar line of business to C.A.V. is Simms Motor Units Ltd., who display the usual comprehensive range of diesel engine fuel injection and electrical equipment and, of particular interest, arc the FH series single-bowl and twin-bowl filters which were introduced at the Motor Show.
Important introductions were made by Joseph Lucas Ltd. at Earls Court and this concern's stand is well worth a visit to see the new 4TR electronic control for alternators. There is also a wide range of fog and long-range lamps and other accessories, including commercialvehicle flashing indicator conversion sets, two new auxiliary switch panels, battery fillers and Screenjet windscreen washer.
The use of printed circuits in place of conventional wiring on instrument panels is featured by S. Smith and Sons (England) Ltd., who as well as illustrating the use of this system on the Ford Corsair car arc showing examples of what can be done on commercial vehicles. Heating and ventilating developments featured by Smiths include the 1500 saloon heating system for double-decker buses and also the Jet-Vent system of individual passenger ventilation which is shown with a refrigeration system that can be used in conjunction with it. On the radio side. the 640T coach radio and passenger address system is featured. The individual components of it can be bought separately and allow a good degree of flexibility; for example, if passenger address equipment is required on only certain jobs the equipment for this can be moved around vehicles in a fleet.
New fog and long-range driving lamps designed particularly for commercial vehicles are featured by Marchal Distributors Ltd. These are the 620/200 Major Fantastic Fog Lamp and 622/200 Major Fantastic Long Range Driving Lamp.
Both lamps are 8 in. diameter and have chromium-plated rims and black enamel bodies. Upright or pendant versions are available. Other exhibits include Marchal sparking plugs and Mixo horni.
Occupying the next stand to Marchal Distributors is its associate company, Trico-Folherth Ltd., where three new chemicals designed to keep windscreens clean can be seen, but where the particular interest for vehicle operators will be the Telma Retarder. This fits in the transmission line of a vehicle and operates electrically to give a braking effect.
An interesting exhibit by Champion Sparking Plug Co. Ltd. is a new electronic Ignition Simulator which has been specially designed by Champion to demonstrate the effects that varying road ' driving conditions can have on sparking plug operating temperatures. There is also Champion's new electronic sparking plug tester, the Plug-Scope, which is a portable oscilloscope that can test all the plugs on an engine at the same time with the engine running. An interesting development in fuel filtration is featured by Automotive Products, this being a new Purolator unit designed for fitting in the pressure line from the fuel lift pump. A clear plastics bowl is incorporated to enable the state of the filter to be seen easily, the filter clement being of the usual Purolator pleated plastics-impregnated paper construction.
There is particular interest for semitrailer operators on the stand of Adrolic Engineering Co. Ltd., where the latest version of the concern's Easy Gear 107 semi-trailer landing gear is featured. The original version of this was first shown at last year's Commercial Motor Show and is based on a design produced initially by Merriworth Engineering Co. Ltd., the semi-trailer manufacturers of Dartford, Kent. Although shown at the Commercial Motor Show, the landing gear has not been marketed in the U.K., but about 1,500 sets have been sold in Europe in the past year. The Easy Gear 107 is of robust construction and has a static loading capacity of 50,000 lb., but as lightalloy castings and rectangular tubing are used the total weight is only 200 lb. A two-speed gearbox is built in. yet the unit costs only a little more than normal single-speed type gear.
Also shown are new versions of the well-known Adrolic stabilizers to reduce the tendency of artics to jack-knife, and interesting exhibits are Expando air hoses arid electric cables for use between tractive units and semi-trailers which have also been developed in conjunction with Merriworths. With these the hose and cable is tightly coiled in a similar way to the lead on the latest telephone hand sets and the need for fittings and springs to keep semi-trailer connections away from the tractive unit transmission is eliminated.
The latest introduction to its range of commercial vehicle assemblies is featured by Primrose Third Axle Co. Ltd. This is called the Trans Load Mk. III, being a combined load transfer and stabilizer unit which is suitable for fitting to most makes of 6-wheeler with a single-drive rear bogie and four-spring suspension system. Air operation is employed and the unit is capable of transferring up to 2.25 tons of load from the trailing axle on to the driving axle, which is particularly useful where traction difficulties may be experienced on site work. The stabilizer unit is designed to eliminate axle hop during braking. For the Show, the Trans
F18
Load Mk. Ill is exhibited in conjunction with a half section of a Primrose balancebeam-type third axle to illustrate the operation sequence. A complete vehicle fitted with a Primrose third axle and the new assembly is available for demonstra
tion purposes. .
Visitors to the Show wishing to inspect products of independent engine makers will find only Gardner Eng:nes (Sales) Ltd. has a stand. One engine is shown, this being the 6LX vehicle diesel which is being shown with a Plessey hydraulic pump for power-assisted steering and a Westinghouse air compressor. The same applies to other chassis mechanical units, the makers of these being notable by their absence. Only Borg-Warner Ltd. is there (with automatic transmission) and these only for cars—and light commercials, of course—although thess. may
find wider application on commercials eventually.
There is a good deal of interest on the stand of Clayton Dewandre Co. Ltd.,
where a number of new items of braking equipment are featured. These include the new braking layout available as optional equipment for Thames Trader vehicles, which incorporate the SC6 air compressor and E brake valve. There is also a new form of power-assisted hand brake which has been developed recently and has a special lever which incorporates a lost-motion design. The Glasgow Show will also be used by Clayton to show for the first time a new type of exhaust brake equipment. This consists of a simple form of exhaust brake incorporating a butterfly valve and operated by a close-coupled pneumatic cylinder. A similar pneumatic cylinder is operated simultaneously to control the fuel cut off of the diesel engine and both the cylinders are actuated through a foot control valve. An optional pressure regulator valve can be included to protect the main air-pressure system against failure in the exhaust brake operating system.
As usual, the stand of The Bramber Engineering Co. Ltd. will contain exhibits of laminated road springs and coil springs manufactured by the concern. Wheel repair facilities will be featured and also on display will be the Bramber Flexitor independent suspension units which are widely used on small trailers. Also for use with trailers are the items of towing equipment manufactured by B. DixonBate Ltd., exhibited by Halley's Garage Ltd. Included are towing brackets from the range of 250 types available, towing hooks and the Dixon-Bate hydraulic towing stabilizer which incorporates two Girling dampers.
Tipping gear makers are represented by Edbro Ltd.,. and Telehoist Ltd. Telehoist will be exhibiting one Model 2LN single, front of body rani, end-tipping gear together with a range of pumps and hydraulic valves: Most interesting from a commercial vehicle point of view amongst the tyre manufacturers' stands is that of Goodyear Tyre and Rubber Co. (G.B.) Ltd. The main feature will be the new Super Hi-Miler announced only last week which is claimed to give high mileage, excellent durability, cool and quiet running and improved traction. Also displayed arc Super Single low-profile tyres which are now available in sizes to replace twill tyres from 7.50 to 10.00 or 20-in. wheels. The latest Super Singles are made in revised rim sizes to standards recently agreed by the American makers of this type of tyre.
Amongst the other tyre makers, there is interest on the stand of Pirelli Ltd. with the Centura Giant, which is a radial ply tyre, having a textile casing and a steelbraced tread. There are no important developments in commercial vehicle tyres on other stands (exhibitors include Michelin, Fisk, Firestone. lndia and
Avon). but on the North British Rubber Co. Ltd. stand, besides U.S. Royal tyres, there is a display of Royalite, nitrile thermoplastic. Of particular interest are wing valances in this material which are now fitted as standard by London Transport.
Two exhibitors of tyre maintenance equipment and repair materials are Apascal Ltd. and Tip Top Vulcanising Products. New items exhibited by the latter arc a liquid buffer and tyre spikes for safety on icy roads and over snow.
Makers of service equipment taking part in the Scottish Show are few; there are only nine in this section, but very many others are represented by the factors taking part with either actual equipment or photographic displays being featured. Lamson Paragon Ltd. is an exhibitor at a Scottish Show for the first time and is providing a comprehensive display of its Garage and Accounting System.
Kismet Ltd. is also exhibiting on its own stand with a selection from the concern's wide range of air and water equipment, including the new KAG.400 Flatorscope tyre inflator. Tecalemit Ltd. is also an exhibitor. but probably the most
interesting new items made by the concern—the Tecspan vehicle lift and Tecomat safety mat—are featured by James Robertson (Factors) Ltd., the maker's Scottish agents. The lift will be demonstrated in a special show, running concurrently with the Scottish Show, staged by Robertson in its warehouse.
Factors dealing with vehicle cornponents include Edmunds, Walker and Co. Ltd. and Geo. and Jas. Paton (Engineering) Ltd. Edmunds. Walker is paying particular attention to braking equipment made by a number of concerns and there is a special display of Girling dampers which are now distributed nationally by the exhibitor. Of special interest among the Paton exhibits are Glacier recticular-tin aluminium bearings, Mintex brake linings and hydraulic hoses and fittings with re-usable ends.
Many stands not mentioned will probably be worth visiting—there may be some surprises. And if your taste is for the luxurious then don't miss the stands of such concerns as Kumficar (Sales) Ltd. and ICarobes Ltd. to see the steering wheel gloves, seat covers and travelling rugs.
