Improved Orient Buckboard

Changes in the Orient Buckboard make the 1906 model a very different machine . from the earlier models of this simple, light, low-priced road vehicle for two persons. While retaining the vertical single-cylinder air-cooled motor, located over the rear axle, the drive, instead of being by direct spur gearing, is by friction wheel and disc to a countershaft and thence by two side chains to the rear wheels. This arrangement provides a very flexible transmission through all speeds from zero to the maximum without gears, enabling the driver to suit his speed exactly to the conditions of travel and the power of the engine. It also results in the avoidance of any noise of meshing gears.

The engine is rated at 4 horsepower, but is said actually to develop 5 1-2 horsepower. The cylinder dimensions are 3 1-4-inch bore by 4 1-4-inch stroke. The friction disc occupies the position of the flywheel on the fngine shaft and has a smooth metal face. The wheel which engages upon it is faced on the periphery with a special fibroid that has remarkable adhesive qualities. Pressure of this wheel against the disc is regulated by a ball thrust in the rear of the disc, which is operated by a left-foot pedal having a ratchet permitting of five different degrees of pressure.

The friction transmission permits of reverse motion at any desired speed up to the maximum forward speed, and is accomplished merely by shifting the friction wheel across the face of the disc to the opposite side. When the wheel is in the center of the disc it is in neutral position, but to prevent wear it can be moved back out of contact altogether. The position of the wheel with relation to the disc is regulated by a hand lever at the side of the car. The maximum speed of the buckboard, as regularly delivered, is thirty-five miles an hour, but special racing front sprockets can be supplied to increase the speed to more than forty miles an hour. A right-foot pedal actuates the brake.

Instead of being mounted directly upon the axle, as in earlier models, the engine in the 1906 buckboard is mounted on the rear of the frame, which is supported by four ip-inch full-elliptic springs on the axles. This reduces vibration to a minimum, and also increases the clearance of the machinery from the ground to ten inches instead of six. An Orient carburetter furnishes the gas mixture. Cooling is assisted by a four- blade fan mounted in front of the motor. A four-cell dry battery furnishes ignition current and a wipe contact Orient timer of French type regulates the sparking. Lubrication of the cylinder and bearings is by a sight-feed oiler operated from the seat.

A “duck back” covers the transmission machinery back of the seat and a hood and dash have been placed at the front, giving the machine a near approach to the form of the larger runabouts. The hood is a storage receptacle. There is also a light metal case beneath the machinery to protect it from dirt. Mud fenders are fitted above all wheels.

The weight of the car complete is 525 pounds. It has a wheelbase of 80 inches, and the seat comfortably accommodates two persons. The standard gauge or track of the machine is 42 inches, but for sections in which the road conditions require it, a tread of 56 inches—standard wagon tread— can be supplied. The body is of ash, natural finish, mounted on a truss frame. Axles are of  1-inch toughened steel. Wheels are 26 inches in diameter, fitted with 2 1-2-inch Goodrich single-tube tires.

The cylindrical gasoline tank at the back of the seat has a capacity of 3 1-2 gallons, sufficient for a run of about 100 miles. In recent tests this machine is asserted to have traversed 121 miles in 6 3-4 hours on a consumption of four gallons of fuel and 1 3-4 pints of oil and, on another day, was run 93 miles in 5 1-4 hours on three gallons of gasoline and one pint of lubricating oil. Immediately following these tests it ascended Old Boston Rock in Boston, an elevation of 562 feet, and climbed the flight of thirty- five stone steps at the top having an official grade of 32 per cent. On the reverse it climbed a grade of 22 per cent.

The Orient Buckboard has been designed especially to adapt it to rural mail service and use by telephone, telegraph and electric lighting companies, but is equally suitable for country use by private owners as a quick and inexpensive means of transportation.

The sales department for these little cars, as well as for the larger Orient automobiles, has just been removed from New York city to Waltham, Mass., where the factory and general offices of the builders, the Waltham Manufacturing Company, are located.
