EASY 10 GET HT TIE HEW II TWELVE Working Parts of Popular Model Can Be Reached With Ease. Easy' and complete accessibility to all working parts of the motor is one of the marked features of the Hal-Twelve car, which is being displayed by the C. A. Quigley company. Each cylinder block of the twelve-cylinder motor has a nickel pressed steel cover, which entirely protects pro-tects the rocker arms and other working parts from dust and dirt. These covers may be readily removed for adjustment of tappets. The carbureter, is set In the 60-degree angle between the two sets of six cylinders cylin-ders with the exhaust pipes on the outside out-side of each block. This enables the workman to get at the working parts of the motor to adjust the valves while the motor is warm. Having the exhaust pipes in this position makes for most accurate valve adjustment, as valve action, ac-tion, to be efficient, must be gauged when the motor is warm. This feature of the twelve-cylinder motor is peculiar to the Hal-Twelve, as most other multiple cvlin-der cvlin-der motor markers build the exhaust Pipes between the blocks, thus making it hard for the mechanic to work on a warm motor without being seriously burned. Clutch and transmission housings are bolted directly to the motor, making a unit power plant which is staunch.lv supported sup-ported on a three-point suspension. The valve camshaft is directly above the crankshaft and is actuated by spiral gears. The side-by-side form of connecting connect-ing rod construction is used and the bearings bear-ings are fitted with shims of the usual type, rendering adjustment a simple matter. mat-ter. The semi-elliptic front and rear springs are of ample dimensions to insure easy riding, and the latter are undorslung and flat under load. They are made from chrome vanadium steel. Stewart vacuum system and power tire pump operated from tile transmission ?ears and an actuating key which throws the gears into mesh, conveniently located in the floor front of the driver's 'scat, are other features.
