(AN this stand will be found examples of sturdy vehicles built on simple lines so that maintenance work is

reasonably easy. The largest chassis shown has a six-cylinderled engine rated at 38 h.p. (the bore and stroke dimensions are 100 rem. and 140 ram. respectively), which gives a total piston-swept volume of 6,597 c.c. As might be expected, the cylinders are cast en bloc and they are enclosed at the top by a detachable head of the Ricardo type— a unit of very simple construction which can be removed and replaced for decarbonizing purposes within one hour.

The crankshaft is accurately balanced and runs on four main bearings Of generous dimensions, all of which are supplied with oil under pressure by a gear-type pump attached to the upper half of the crankcase with the suction side extending into the oil reservoir. Four speeds are provided by the gearbox, the drive being transmitted to an underslung worm-driven rear axle by a two-piece cardan shaft with Spicer joints at the front and rear, Both band and foot brakes are independent ; they are of the internal-expanding type, operating an separate drums of large diameter on the rear wheels. A neat form of adjustment device is arranged.

A few dimensions concerning the chassis may not here be out of place. With wheelbase and track measurements of 15 ft. 71 ins. and 5 ft. 8 ins, respectively, the overall length works out at 23 ft. 7 ins.; a body space of 19 ft. 4 ins, is permitted. The loading line, with 36-in. by 6-in. tyres, is 2 ft. 2 ins. high. Only one bare chassis is shown—a six-cylinder M.A.B. ambulance model, which has been designed right from the start for its particular work. To this end, offset drive is utilized, the engine and transmission being positioned in the chassis so that they are in line. The height of the' frame when the vehicle is loaded is but 18 ins, With wheelbase and track dimensions of 11 ft. 9 ins. and 5 ft. respectively, there is ample space available for fitting a roomy body capable of carrying a nursing staff, in addition to a fall complement of stretcher patients.

The Dunlop steel wheels are shod with 33-in. by 6.75-in, low-pressure tyres and four-wheel brakes with Lock heed operation are employed. Four forward speeds are provided by the gearbox and the price of the chassis is £680, or, complete with an ambulance body, £160.

A four-cylinder 23 h.p. low-loading chassis for municipal work and refuse collection is on view, complete with a 3-ton, three-way hydraulically operated tipping body. There is also a chassis fitted with a band-operated end-tipping body and a 23 h.p. four-cylinderengined 30-cwt. laundry van.
