THE PARIS SHOW
Numerous New Models will Figure Amongst a Collection of Interesting Exhibits. Oil Engines to the Fore. Improvements in Bodywork Design and Details
THE Paris Industrial-Vehicle Show, which' opens on November 28th, promises this year to be of un
usual interest and importance. The French commercial-motor industry has always been rather inclined to lag behind the private-car trade, but manufacturers have recently made a spurt in order to get into line with existing conditions, and signs of real progress will be seen in this show.
Famous coachbuilders such as the Saoutchik and Million-Guiet companies, which have hitherto made only the highest class of luxury body for private cars, will for the first time be showing commercial bodywork.
Oil-engined chassis will be well to the front, four or five makes at least being exhibited ; so' also will the gas-producer, which has lately received further official encouragement in France.
An important feature of this year's show will be the practical-demonstration section outside the Grand Palais. One concern alone will have no fewer than 22 vehicles in action, covering almost every phase of commercial and municipal work.
An interesting novelty amongst the oil engines will be the new three-cylindered six-piston Peugeot-Junkers unit, exhibited by the Compagnie Lilloise de Moteurs. This is a development of the company's well-known twin-cylindered two-stroke engine with opposed pistons.
The La lily company will be showing three new models, one of which is a competitively priced 2i-ton chassis for goods or passenger work. The chassis is made in short-wheelbase and longwheelbase forms.
This chassis has a four-cylindered overhead-valve engine of 80 mm. bore and 120 mm. stroke, with magneto igni' tion and therrao-siphon cooling. Other features are a single-disc dry clutch, a separate four-speed gearbox and a worm-driven axle. Mechanical-servo braking is employed for the front wheels, whilst the rear-brake controls are independent.
In the case of the short-wheelbase type, a special pinion in the gearbox provides a drive for tipping gear.
Another new Laffly chassis is the L.M.60 Special. This is a fast, lowlevel vehicle, with an eight-litre sixcylindered engine developing 120 b.h.p. The engine has push-rod-operated .valves, battery ignition, and pump circulation for cooling.
A slightly smaller version of the above chassis will also be shown; this has a 90 mm. by 130 mm. six-cylindered
engine of similar design to the above and developing 75-80 b.h.p. • Lastly, an oil-engined model based on the L.M.60 Special chassis will be displayed. This vehicle is equipped with the new 85 b.h.p. Peugeot-Junkers twostroke oil engine mentioned above.
Whilst in general lines the engine resembles the two-cylindered model, many important improvements are incorporated. The question of weight reduction has received careful attention. Separate cylinders are employed.
Light tubular connecting rods are now fitted to the lower pistons, where the rods function normally, and light forgings are used for the upper ones.
In addition to the new models Mentioned the Leffly concern will be showing a full range of its standard vehicles
for all industrial purposes. An important group of Laffly municipal vehicles will be engaged on demonstration work outside the Show.
In addition to its usual fine display of fire-fighting outfits the Delahaye concern will be showing 14 vehicles ranging from 9 h.p. delivery vans up to 61-tonners, including a 25-seater four-door coach having the maker's new sixcylinder III chassis. This hak monobloc engine of 98.5 mm. bore and 127 mm. Stroke, with side-by-side valves and a four-bearing crankshaft.
Other Delahaye exhibits will include three light delivery vehicles, a baker's 12 h.p. (French rating) van, a 2-ton postal van, two 4-tonners for multipleshop concerns, a caravan and several coaches incorporating the new III chassis, a 5f-ton refuse lorry and a polished 6f-ton chassis.
The S.O.M.U.A. concern will be showing 11 vehicles in the Salon and five more on demonstration work outside the Grand Palais. On this stand will be a polished chassis of the R.Z.S.A. 6f-ton type, which has a six-cylindered 90 b.h.p. engine, with superimposed valves.
This model of chassis, which is designed for passenger work, will also be shown carrying a 35-seater coach body. A feature of the design is the double-reduction gear on the rear axle. The vehicle has a good turn of speed. Another exhibit will be the new G.10.S.A. 10-ton chassis for general service ; it has a Dents six-cylindered oil engine developing 80 b.h.p. at 1,200 r.p.m.
The G.10.S.A. chassis will also be shown with the standard Somua sixcylindered petrol engine. The Somua "saloon" fire-engine, for long-distance will again be shown, with various improvements. Another interesting exhibit will be the new pavement
sweeping and cleaning machine; described recently in The Commercial Motor, whilst a further novelty will be an 8-ton chain-track tractor with a 30-ton trailer.
On demonstration work outside tho Salon, one of the most juteresting vehicles will be a new road-sanding machine incorporating the 10-ton Somua chassis, This vehicle is said to be capable of covering, in fi'Ve minutes, 1,000 sq. m. of road with a 6-mm. layer of sand.
On the Renault stand, particular interest will centre around the new oilengined model. All Renault heavy-duty chassis and tractors can now be supplied with four or six-cylindered oil engines. The power. units are of the
four-stroke type, employing Bosch fuel pumps. Both four and six-cylindered models have the same bore and stroke, namely, 115 mm. and 170 mm. respectively.
The feature of Renault products is the relatively small number of standard parts employed in manufacturing a large range of vehicles.
Twelve different types of chassis will be exhibited, comprising three light delivery outfits, four light-duty chassis carrying up to 3f tons, three heavy-duty chassis for loads from 51. tons to 8 tons, and two tractors with trailers carrying from 6 tons to 15 tons.
In this range only five different types of engine are employed (exclusive of the oil engines), three being four-cylindered models and two six-cylindered units.
The Lath). company will be showing 11 vehicles on its own stand, whilst another five Laths will be seen on the stands of various coachbuilders. In addition, 22 Latil vehicles will be employed in practical demonstrations.
An interesting exhibit will be the Latil snow-plough incorporating the K.T.L. tractor chassis, the wheels cf which are equipped with chains and the well-known Latil folding spuds.
Remaining Latil exhibits will include the P.B.3T. tractor-trailer outfit, seen last week at Olympia, a R5 chassis, a 8.P.B.38. model, a P.B.3, a P.B.2, and P.B. pattern, all in chassis form. Complete vehicles to be shown will include a coach with a Currus body on the S.P.B.3 chassis, a -big delivery van for the Galleries Lafayette (also with body. by Currug), a snow-plough, as mentioned above, a cold-storage van employing the S.P.R3S. chassis and a cattle carrier using the B.5 long chassis.
Latil vehicles on demonstration work will include refuse-collecting lorries, water carts, petrol tank lorries, buses (with bodies by Paquette), lorries with Fillet and Geneve tipping arrangements, heavy duty lorries and vehicles with Peugeot-Junkers two-stroke oil engines.
An . all-round improvement will be found in French commercial coachwork at the Paris Show. A. notable point will be the employment of real leather upholstery, hitherto almost unknown in French commercial work. Interior
finish has been vastly improved. , A fine coach body for Colonial work will be shown by Messrs. Breteau 'Freres. The interior of the coach, which is divided into three compartments, is panelled throughout in mahogany and in the rear saloon the seats are arranged longitudinally with a central folding table between them.
Another Breteau. exhibit will be a publicity vehicle for the Menier Chocolate Co. The rear compartment of the body is arranged for serving, hot chocolate, a stove. and a milk refrigerator being car ried, whilst there is a Wireless loudspeaker mounted in the roof. Spare wheels are carried in a cupboard Immediately, behind the driver's cab.
Amongst a range of industrial bodies to be exhibited by Renoux and Co. is a smart Citroen six-cylinder 16-seater bus for local service. The body has the usual Continental rear platform, accommodating 10 standing passengers.
Another Renoux body, also on a Citroen chassis, is destined for postal service in the suburbs of. Paris. A sliding hatch at the back of the driver's seat is used for taking in sacks of letters that are collected, whilst an extending grille in the centre of the body allows sacks and packages that-have been collected to be kept separate.
The Saoutchik concern will be showing a 35-seater coach body, made-entirely in aluminium and carried'Cu a Lally chassis. Million-Guiet, of Levallois, will stage a large Laffly caravan.
