| 408 BERLIN SHOW (Continued from page 398) front drive, the 61-cu. in. front drive (both with four-cylinder L-head engines) and the 152-cu. in. six cylinder. In the 61-cu. in. the combustion chamber form has been improved, the front shock absorbers have been raised to increase the ground clearance, and the speedometer has a larger dial. In the 122-cu. in. model the oil pressure relief valve has been increased in size, for better control of the oil pressure; the three-way cock controlling the reserve compartment in the fuel tank (front tank) is now mounted on the instrument board, and the electric cables are now of different colors, to facilitate tracing troubles in the circuits. The windshield is now of V type. The six-cylinder model is now equipped with an oil cooler located in the top tank of the radiator. Bodies of this model have been improved by providing wheel covers for the rear wheels. The fuel filler is now on the right rear fender and there is a three-way fuel valve let into the floor at the driver's seat. An oil thermometer is an additional fitting on the instrument board. This 58-hp. car is said to have a maximum speed of 78 m.p.h. and a cruising or sustained speed of 72 m.p.h. The two Ford models, a four-cylinder 73-cu. in. of 34-hp. rating, and the V-8 of 90 hp., have had changes made in the crankshaft, the rear bearings now being larger, so that all bearings (which are of the steel back, silver-cadmium type) are now interchangeable. Piston pins are now prevented from drifting by snap rings in grooves in the piston bosses. On the V-8 the interrupter has two springs and interchangeable contacts. This engine is now fitted with a Solex downdraft carburetor, claimed to give greater power and better fuel economy. The tubular propeller shaft has been replaced by a solid one which is supported in the propeller-shaft tube at its middle of its length by a roller bearing mounted in rubber. The steering gear is now of the worm-and-roller instead of the worm-and-sector type, and the reduced friction loss has permitted of decreasing the gear ratio by 8 per cent. The mechanical brakes now have servo action. Of the Hansa cars, now known as the Borgward, only the six-cylinder 122-cu. in. remains. Instead of the box-section backbone frame, a frame with two box-section side members of less depth is now used. These are drawn in at the middle, as in the two small Mercedes-Benz models, and open up at the front to receive the powerplant. The single transverse spring at the rear, mounted on top of the differential housing, connects with its ends to the axle tubes through rubber “turret” springs acting as supplementary springs. The floor of the car is entirely flat and the tubes of the chassis lubrication system are now located above the frame. Hanomag exhibited its new 79-cu. in. model, described in AUTOMOTIVE INDUSTRIES of Feb. 4, and also its older 140-cu. in. six-cylinder model. Maybach this year showed only its 140-hp. car, in the engine of which the original leaf-type valve springs THE OLD STANDBY... sets a NEW STANDARD! Molded parts from Bay Manufacturing Division The Electric Auto-Lite Company Pioneer among plastics for those important parts of automobile ignition systems which must resist heat and cold, dirt and oil, weather and wear, molded Durez is still the undisputed leader in this highly technical field. Today, more Durez is used for distributor heads, rotors, coil tops and spark plug shields than any other single material. Living up to the leader's obligation of setting the pace in progress as well as volume, Durez has recently come forward with a special compound for ignition parts that's the best yet! This material combines increased dielectric strength with higher resistance to arcing and corrosion than any before it.
