The Interesting Karrier CYR Model, Designed to Give Maximum Body Space With a Minimum Overhang an d Without Sacrificing Accessibility.
IN almost every branch of municipal enterprise /Carrier Motors, Ltd., Karrier Works, Huddersfield, has been a pioneer in the production of motor vehicles and appliances designed specifically to meet the widely divergent requirements.
Karrier municipal models have been adopted by over 100 prominent public authorities in this country alone, the products supplied comprising road sweepers, washers and waterers, gully emptiers, tipping lorries and many other types, and a large number of .valuable repeat orders has been received for these.
The company is, however, not resting Ou its laurels, and the above range has recently been augmented by a new lowloading short-wheelbase 2-tonner designed for the more rapid, hygienic and economical removal of house refuse. It has been designated the CYR model, and its layout is such' as to give maximum body. space With minimum overhang. Other important features are easy marunuvrability, a good speed when loaded and a body level which will enable loading to be carried out rapidly and easily, and, what is a very important point, these features have been obtained -without any undue sacrifice of accessibility or prejudice to easy maintenance—in fact, the new product, which is of the forward-control pattern, is on simple and orthodox lines throughout.
With a wheelbase of 9 ft., the diameter of the turning cirele is as small as 32 ft., whilst the top of the deep channel-section frame is under 2 ft. from the ground when loaded, and to obtain 'this low level the chassis has been mounted on 'small wheels, but the tyres fitted 4re 26-in. by 3i-in. solid, with twins at the rear, which are quite suitable for the intended load.
An end tipping body C42
10 ft. 6 ins. in length and of 7 cubic yards capacity can he mounted on this chassis without any cutting away for whee arches.
Although it is designed primarily for municipal use, the CYR chassis should prove of service in many other spheres of transport where the requirements of particular trades may demand a lowloading type of vehicle capable of being operated in narrow thoroughfares or other restricted areas. For this class of work, a body 11 ft. 7 ins, long can be accommodated.
The highly efficient four-eylindered engine has a turbulent-type detachable bead. • It develops 26 b.b.p. at a normal engine speed of 1,000 rpm., and 40 b.h.p. as a maximum. The bore and stroke are 95 mm. and 140 mm.
respectively. Carburation is effected by a Zenith instrument with an integrally cast induction pipe. The cooling water is circulated by a .centrifugal pump driven by a belt from the front end of the magneto-drive shaft: The lubricant is fed under pressure from a large oil pump in the sump, which is driven by spiral gearing from the camshaft. Surplus oil passes through an adjustable relief valve to the timing wheels and magneto-driving chain.
An adjustable cone-type clutch faced with fabric and provided with a clutch stop is utilized..
The gearbox is a one-piece casting with shafts and pinions of niekel chrome steel. The gearbox is carried in the same sub-frame as the engine, thus ensuring accurate alignment. Right-hand control is employed, tile' gears being positively locked by springloaded plungers operating on the selector rods.
Between the gearbox and rear axle is a tubular propeller shaft provided with a fttbrie-disc joint at each end. The final drive is by an overhead worm, and the axle is a full-floating one.
Taper roller bearings are provided for all the wheels. .
The suspension is by long, semiz elliptic springs, whilst auxiliary springi
are provided at the rear, these only coming into action during an overload.
Two independent brakes are employed, a hand-operated internal-expand' lug type for the rear wheels and a footcontrolled external-contracting on the trMasmission. The latter has cast-iron linings, whilst the rear-wheel brakes hai(e bonded-asbestos facings. The Innlees are compensated and their adjustment is simple.
Steering is effected by a gear of the worm-and-wheel type, end there are throttle and ignition controls on the steering column, these levers being Pleeed at a convenient point. The equipment includes side and tail oil lamps, a 12-volt lighting set, mileage recorder, mirror, etc„ and grease-gun lubrication throughout. A 14-gallon tank is mounted on the dash.
Dimensions .other than those given are : Track, 4 ft. 0 ins.; platform space, 9 ft. 101 ins.; chassis length overall, 14 ft. 54 ins.; chassis width overall, 5 ft. 11-ins.; ground clearance, if ins. ; chassis weight, 1 ton 14 cwt. 2 tirs. The gearbox ratios and speed's with the engine running at 1,000 r.p.m. are Top,
