The Daimler Motors
The Daimler Motor Company, manufacturers of stationary gas, gasoline, and kerosene motors, and gasoline motors for boats, carriages, street-railway cars, fire engines, and portable electric lighting, are the sole owners of the United States and Canadian patents of Gottlieb Daimler, of Canstadt, Germany.
Their motors are all of the four-cycle compression type, following the principles formulated by M. Beau de Rochas, and carried out practically by Otto and Daimler in Germany, and now made by this company with many improvements derived from experience. All the valves are of the poppet style, closing automatically with springs. In the earlier engines and those of the duplex style with a single crank, the governing was made by a miss in the push-rod blade on the exhaust-valve stem by which the exhaust valve remained closed through a single cycle or more, as required by the action of the governor —the governor being of the horizontal centrifugal style, located in the pulley on the main shaft or in the fly-wheel when an outside fly-wheel is used.
The operation of the governor is transferred through a grooved sleeve to the lateral arm of a bell-crank push-blade on the push-rod of each cylinder, by a vertical pivoted lever carrying a stop-block, which is thrown out and into contact with the arm of the bell-crank push-blades, and makes a miss-opening of the exhaust valve, as shown in the duplex motor (Fig 156) and also in the single-cylinder motor (Fig. 155). By this arrangement the movement of the piston, with the exhaust valve closed, simply compresses and recompresses the burned gases, and allowing no fresh charge to enter the cylinder until by the return to normal speed the governor allows the push-blades to act on the exhaust-valve spindle.
The ingenious mechanism by which the alternating motion of the valves is secured without the use of gearing for both the double and single cylinders is worthy of notice. By this arrangement the reducing-gear and its noise have a substitute in the eccentric double continuous groove, in which sliding-pin blocks perform the operation of a single eccentric for each cylinder. The pin-blocks and push-rods being off from a radial line, allow the blocks to cross successively the intersection of the eccentric groove.
In the new style of motors of this company the adaptation to the most ready fuel to be found in all parts of the world (kerosene), has made this style of motor a most desirable one for the foreign trade as well as a most economical one for home use. |
