First Details of the 2i cwt. New Carden Light Delivery Van for the Tradesman and Commercial Traveller.

IT IS difficult at first to realize that a reliable end speedy light van to carry loads of 2i cwt. can lae built to sell at such a low figure as that referred to in the above heading, but this has actually been done by Arnett and Harrison, Ltd., of 22, Hythe Road, Willesden, London, N.W.10. The New Carden van must not be confused with the vehicle called tlse Carden, which was marketed by another company. Tbe only reason that the name has been retained is that the engine and gearbox unit is constructed under the patents of Capt.

Carden ; the remainder of the chassis has no resemblance to its prototype and is far more normal, both in its appearance and general design.

In. spite of the fact that the complete van turns the scale at only 5t cwt., the frame is strongly built with channel steel members and laminated springs are used all round, those at the rear being of the semi-elliptic type, whilst quarter-elliptics are employed for the front axle.

Nothing is contained within the space covered by the bonnet except the petrol and oil tanks and the steering post, whilst the whole engine and gearbox unit can be removed and replaced by one man within an hour, so that if a fleet of these little vans were employed and a spare unit ken-Lein stock it. would be quite unnecessary to take a van off the road for more than an hour in case of engine trouble, The main and most interesting part of the chassis is undoubtedly the novel power unit, which is quite unlike that on any other vehicle. There are two cylinders of 75 mm. bore and 80 mm. stroke, which work on the two-stroke cycle and have a horse-power of 6.98, according to the ;R.A.C. rating; these cylinders have detachable heads and are held to the crankcase by long bolts; they are widely separated and their connecting-rod big-ends bear on crankpins at, the

ends of the crankshaft. •

In the centre of the crankshaft is sitnated a multiple-disc clutch, the drive from which is conveyed vie a spur pinion to aslarge spur wheel running freely on the solid, live rev axle. Two pinions of different sizes are carried on a layshaft, and the smaller of these meshes with another pinion firmly secured to the axle. The gear changes are effected by a, sliding pinion provided with internal teeth and dogs, the ratios being 5-1to 1 and 14i to 1.

The rear axle itself runs in Timken adjustable roller bearings, which are carried in housings attached by IT clips to the rear springs. Carried in two lugs on the crankcase just above the cylinders is" a stout tube through which rims a steel bar, the'ends of which are threaded and provided with locating nuts ; these ends are carried in sockets formed in the rear ends of the main-frame side-members, so that much of the weight of the whole engine and gear unit"is carried ber the frame, and therefore sprung. Actually as the axle rises and falls the whole unit turns on the frame bar, svhicia acts as a fulcrum and also takes the drive, for the front ends of the two springs are loosely shackled. Ignition is attended to by an MI,. high-tension snagneto driven direct from the near-side end of the crankshaft, whilst the correct mixture is supplied by a single-lever, automatic Zenith instrument, which is situated between the cylinders.

The van is equipped with two brakes, both of which make use of a single wide drum bolted to the off side of the back axle' two independent hands lined with Ferodo providing the necessary friction.

Starting is effected by a long lever lying along the off-side running heard this is connected' to a reek which meshes when required with the large spur wheel in the crankcase.

We have already refereed to t h e clutch. The plat as of this are normally pressed together by a face cam which is operated by a rod passing through the crankcase and held by a tension spring; a pull on this rod by means of the clutch pedal releases the plates.

Direct Ackerman steering is employed and the stub axles rotate in ball bearings. The wheels are of the steel-disc type and have 650 mm. by 65 mm. tyres.

Lubrication of the engine is effecited by a Best and Lloyd pump with sight feed situated on the dash, and 4-4 gallons of fuel can be carried in the petrol tank.

The following dimensions may be of interest :—Overall length 10 IL, width 3 ft. 10 ins., wheelbase 7 ft., track 3 ft. 1i ins.

The equipment includes windscreen, hood, horn, oil lamps, number plates, tool kit, etc., end extras such as a spare wheel, speedometer and side curtains can be supplied at reasonable prices.
