An Ingenious and Inexpensive Threewheeled Machine for 2 ton Loads
FOR many years Karrier Motors, Ltd., Huddersfield, has been well known as a maker of refuse-collection vehicles. Nothing more striking has emerged from this factory than• the new Karrier Colt three-wheeler, which, last week, made its initial bow at the Public Health Congress and Exhibition.
In chassis form it costs t210, and a simple type of refuse-collection body with a hand-tipping gear should not cost more than, say, 160, so that the needs of the local government authority with a small area to cover and a shallow purse are well met by the new model. The actual exhibit which was shown at the Agricultural Hall, with a Bromilow and Edwards tipping gear and an elaborate body with dual-pedal control for the dust-trapping shutters, costs 1400.
The Colt is listed to carry a 2-ton pay load, or a gross load of 2i tons. The engine is a two-cylindered water-cooled horizontally opposed type, developing a maximum of 17 b.h.p., and having a capacity of 907.2 c.c. It has a positively driven dynamo, from which the distributor drive is taken, and the coil is mounted above the dynamo.
The engine drives through a single-plate dry clutch, having six main springs and three toggle levers, to a unit-mounted gearbox with a ball control directly above it. It is controlled by the driver's left hand. The engine-and-gearbox unit is carried in a three-point-suspended rigid sub-frame. Behind the main gearbox is a chain-type reduction box'," carried upon the main frame ; this takes the torque reaction. The drive is by a duplex roller chain in an oil-bath, with external tensioner.
From the reduction box to the rear axle the drive is by a propeller shaft with fabric-disc joints, and final drive is by bevel gears. The wheels carry 18-in. by 5-in. solid tyres, or, if preferred, 22-in. wheels may be specified. The steering lock is
enormous, because the front .wheel may be turned through 180 degrees. This wheel is carried by a fork and the suspension at the front is by two semi-elliptic springs ; those at the rear are underslung.
Both brakes operate on the rear wheels, the hand brake being of the expanding and the foot-brake of the contracting type.
Conventional controls are employed, and the tipping gear and its screw are housed within the cab.. The cab roof tips with the body.
An interesting alternative consists in the use of this chassis as a tractor and the employment of existing horse-drawn refuse vehicles, minus their front wheels, as semi-trailem Interesting data in regard to the new machine are :—Tank capacity, 4?., gallons; wheelbase, 8 ft, 1 in. ; road speed, at 2,000 r.p.m., 12.15 m.p.h.; turning circle, 16 ft.; platform space, 7 ft. 6 ins.; loading height, 4 ft. 7 ins.; overall height, 4 ft. 6 ins.; angle of tip, 50 degrees; platform height, 1 ft. 10 ins.
