"Trebert" 1907 Touring Car
The Trebert Gas Engine Co., 163 Main street, Rochester, N.Y., manufacturers of "Trebert" motors and change gears, are now building complete cars, their 1907 product being the 30 H.P. touring car here shown. The motor is of the 4-cycle, four cylinder, water-cooled type, and it is of their own make. The valves are large, both are mechanically operated, and are made of special forgings. The cylinders are so designed as to allow the valve stem to pass thru the water jacket. The valve chambers are also water jacketed. The entire heating surfaces of both cylinders and valve chambers have water circulation. The spark plug is placed above the inlet valve, allowing the clean charge and suction to cleanse the spark plug, and as the exhaust passes out on the opposite side, this prevents the exhaust and soot from carbonizing and short circuiting the spark plugs.
The cam shafts are directly under the valve stems and these cams and valve lifts and so constructed and arranged that there is no pounding. The valve lifts revolving, insures life to both cams and lifts. The valve chamber heads are screwed in to the head of the cylinder, so that they may be easily removed.
The motor is made of aluminum, with 10 per cent nickel alloy, and has a center bearing cast to the frame and provided with oil pockets. Thus the oil must pass thru the bearing before it leads to the crank pit. By this means the center bearings are thoroly (sic) oiled. The bearings, which are of large size, are made from silver bronze.
The crank shaft is made of a weldless steel forging, with a bearing between each pair of cranks and a large disc for holding the flywheel. Its connecting-rod bearings are 2 ½ inches wide. The crank pit may be removed without disturbing the crank bearings. The fly-wheel is bolted on to the crank disk, and can be easily removed and replaced in position without of its becoming loose or running out of true. It is also turned out to receive friction disk for transmission gear. The carburetor used is a "Buffalo" provided with auxiliary air vent. Ignition is of the jump spark type with a coil mounted on the dash, using a distributer.
Transmission is of the shift gear type giving three speeds forward and one reverse, the high speed being direct. The gears are made of steel forgings, are very accurately cut and case hardened. They are of large size, with 1 inch face and six pitch. The shift gear is a double gear with clutch at one end to engage in driving gear for high speed. No two gears can mesh at the same time. The shaft on which the shift gear works is 1 3/8 – inch square. The case is made from aluminum and is divided in center. The weight of the transmission gear is 78 ½ lbs.

The steering device is made very strong, is of approved type, with the spark and throttle levers attached to the steering post. Four brakes are provided on the rear hubs, 2 internal and 2 external.
