BY reason of its striking price and design, there is little doubt that the new Lance chasais for 32-seater singledeck buses or coaches will continue to attract much attention. The reason for this interest is that the specification is not only completely modern in every respect and bears the ball-mark of Dennis manufacture, but the price asked is £595, with either forward or normal control. This is, of course between £100 and £200 lower than the average figure ruling for this class of machine. Such a saving cannot be ignored in times like the present
As it was fully and exclusively described in our second Show Number, it will suffice to recall the leading details of the specification. The four-cylindered engine has the gearbox mounted in unit with it, and drives through an open propeller shaft to an underslung-worm axle. The service brakes on all four wheels are operated through a Marelli servo and Lockheed hydraulic mechanism. An interesting point is that the brake-shoeoperating cylinders are outside the cover plates, thus ensuring isolation from the heated brake shoes. In the rear-wheel drams all four shoes are of no less a :width than 64 ins. "
Another striking passenger model is the Lance double-decker. No fewer than three examples of this are on the stand. One is in chassis form and reveals a considerable number of improvements, principally in the form of a revised frame with wide flanges, a special kind of cross-member and diagonal bracing amidships. The six-cylindered engine permits removal of the cylinder head without disturbance of the valve timing, and a point well worthy of inspection is the plates on the near side of the bonnet, which serve to separate the air streams passing by the exhaust manifold and the dynamo. This separation ensures that the electrical gear does not suffer from the effects of too high a temperature. In this model the dash plate functions
as a cross-member, and other new features include an oil filter and cooler at the front of the crankcase, a corrugated oil sump, and the special mounting of the Silentbloc bearings in all the spring shackles. The chassis costs £1,095.
Another Lance chassis is shown with 55-seater Brush body, the coachwork of which is priced at £750. The bodywork of this vehicle is handsome in appearance externally as well as internally.
Thirdly, there is the 48-seater type with Metropolitan Cammell all-steal body. This type of coachwork is receiving special attention at the present time, important companies having purchased vehicles With all-steel bodies.
During the past two years the Arrow chassis for single-deckers has made much headway. This is a six-cylinder model with offset transmission, servo four-wheel braking, and the special feature of engine accessibility referred to in the case of the Lance. This exhibit bears a luxury coach body of Duple make, intended to carry 29 passengers. In the form shown the price complete is £1,650.
Turning now to the goods range, there are two examples. The smaller is a 30-cwt. chassis of the forward-control type. In general, it follows the
lines which have made this machine a favourite for light transport duty. New features are the distinctive type of radiator, whilst the provision of forward control is an introduction dating from this year. With an 11-ft. wheelbase, this model permits the mounting of a body 12 ft. 10 ins. long. The output of 40 b.h.p. ensures a good standard performance, whilst the frame height of 2 ft. 3! ins. gives a reasonably low loading line. This mar-bine costs £315, whilst a mechanical tyre pump costs £10 extra, and a starter is included for £9 extra.
The second goods machine is a 3ton chassis. This is a new model which retails at 1555, plus £25 for the allsteel cab. By reason of its low initial cost, this model is sure to find a ready market In many respects its specification follows that of the Lancet. The frame is solidly constructed and braced by a special front cross-member, which also forms a bumper bar and a support for the starting handle and front wings. The engine has a two-piece cylinder head to facilitate maintenance work, and, in order to ensure proper vaporization, the inlet passage passes upwards through a portion of the exhaust manifold. A detail refinement of a practical nature is the torsional vibration damper incorporated in the propeller shaft, whilst Silentbloc mounting for the steady bearing should aid in ensuring silent transmission. This model also has servo braking, coupled to hydraulic operation for the shoes in all four wheels.
Finally, there is a 100 b.h.p. six-cylinder fire-engine of the wagonette type. The 600-70Q-gallon turbine pump is mounted amidships and has a suction inlet at each side, also one pointing to the front At each side there are two deliveries and a group of engine controls. This machine costs £2,000 as shown.---Dennis Brothers, Ltd., Guildford.
