| 708 THE AUTOCAR, October 23rd, 1920. The 1921 Calcott. and the striking and interlocking gears are contained within the box. The gate change is carried to the right-hand side of the driver by an extension of the gear box casting so that it is independent of the main frame. Behind the gear box a large Hardy fabric universal joint and an exposed propeller-shaft transmit the drive to the bevel driven back axle, a similar universal joint being interposed between the end of the propeller-shaft and the pinion, this joint replacing the sliding joint formerly used. A spiral bevel drive is utilised on the new models, and the weight of the car is not carried upon the axle shafts, but upon the mild steel sleeves which project from the central bevel casing. A large oil filling orifice is provided, and is capped and fitted with two wing nuts, so that replenishment of lubrication is not a difficult matter. Large brake drums on the rear hubs accommodate two concentric pairs of expanding shoes, operated by the side brake lever carried on the main frame and by the brake pedal. The frame is of the ordinary pressed channel steel construction, inswept at the front to give a good steering lock, and upswept at the rear to give clearance at the back axle casing. In addition to the cross members this frame is strengthened by the sub-frame which carries the gear box. Springing is by semi-elliptics of good length both front and rear, the rear springs being carried outside the frame and as near to the rear wheels as is possible. Steering is by worm and sector, and together with the front axle is on standard lines. Quadrants above the steering wheel carry throttle and ignition controls. The petrol tank is situated in the dash and has a capacity of six gallons. Detachable steel wheels are shod with 710 x 90 mm. Dunlop Magnum tyres. As regards bodywork, the standard two-seater is finished in grey with black upholstery, black wings and valances, and nickel-plated fittings. The equipment includes a flush fitting speedometer and clock, hood and screen, spare wheel and tyre, electric lighting and starting, horn, and complete tool kit. The double dickey seat is very comfortably arranged, and the occupants are sufficiently low down in the body to be protected to a certain extent from the elements. The rear portion of the dickey hinges upwards and backwards, and is heavily padded, forming the back of the seat. In addition to this model a small coupé body may be fitted, or, if an even more luxurious type of body is desired a small two-three-seater limousine body is available. Yet another model with a four-seater body, similar in finish to the two-seater, appeals to those who require a small family car. The prices of the two and four-seater touring cars respectively are £550 and £625, that of the coupé being £650, and of the limousine £750. Examples will be exhibited at the Show by the manufacturers, Messrs. Calcott Bros., Ltd., Coventry. The layout of the Calcott chassis is on orthodox lines. Three fabric disc universal joints are now fitted, and the final drive is by spiral bevel. THE NEW 19.6 H.P. CROSSLEY. SOMETHING of a sensation is likely to be caused at the Show by the 19.6 h.p. Crossley car, described and illustrated in the last issue of The Autocar. Apart from a more than usually perfect Show finish on the chassis, interest is sure to be aroused by the mechanical features. Grease plays no part in the scheme of lubrication, and the special caps of the wick feeding oil cups are in the nature of an inspiration, because of the ease of manipulation and the safety from grit distribution. Cast iron pistons of unusual design, clever detail work in the oil pump arrangement, neatness of electric wiring in the dash, methods of mounting the clutch member, and the gearshafts are all points which merit inspection.
