In general construction this Benz engine was somewhat similar to the Green engine already described; the overhead valves, fitted in the tops of the cylinders, were similarly arranged, as was the cam-shaft; two springs were fitted to each of the valves to guard against the possibility of the engine being put out of action by breakage of one of the springs, and ignition was obtained by two high-tension magnetos giving simultaneous sparks in each cylinder by means of two sparking plugs this dual ignition reduced the possibility of ignition troubles.

In this engine the steel cylinders were secured to the crank case by flanges, and radiating ribs were formed around the barrel to assist the air-cooling. Inlet and exhaust valves were actuated by push-rods and rockers actuated from the second motion shaft mounted above the crank case; this shaft also drove the high-tension magneto with which the engine was fitted.

This hill was protected by, among other devices, an intricate barbed wire entanglement charged with a high-tension electric current, the penetration of which proved to be a task of almost insuperable difficulty; nevertheless, it was eventually accomplished.

Röntgen discovered that the invisible rays, or radiation, emitted from certain parts of a high-vacuum tube, when high-tension discharges from induction coils were passing, possessed the curious property of traversing certain opaque substances as readily as light does glass or water.

The president of Zamora had profusely thanked the "gringo" in charge when he presented himself in town with the body. On pay-day the manager went and came from the bank with two immense revolvers and a loaded rifle. The current supplied by the rapids of "Platanal" is carried on high-tension wires to several cities far distant, including Guanajuato, a hundred miles away.

The reduction of the voltage was accomplished as follows: The 100,000-volt alternating current was received through an oil switch and was conveyed to a high-tension current distributor made up of three lines of copper tubing, thus forming the source of power for this station.

Overhead valves were adopted, and in order to make these as large as possible the combustion chamber was made slightly larger in diameter than the cylinder, and the valves set at an angle. Dual ignition was fitted in each cylinder, coil and accumulator being used for starting and as a reserve in case of failure of the high-tension magneto system fitted for normal running.

Thus there entered into the high-tension atmosphere of the sensationalized Patriot the relaxing quality of humor. Under the ingenuous and acquisitive Sheffer, whose twins achieved immediate popularity, it developed along other lines. Children cried for them, and laughed to exhaustion over them. Not less did the mentally exhausted business man writhe abdominally over their appeal.

Ignition was by means of a high-tension magneto of the two-spark pattern, and with a total weight of 300 lbs. the maximum output was 102 brake horse-power, giving a weight of just under 3 lbs. per horse-power. One of the most successful of the two-stroke cycle engines was that designed by Mr G. F. Mort and constructed by the New Engine Company.

This machine ran on three wheels before leaving the ground, a central undercarriage wheel being fitted in front, with two more in line with a right angle line drawn through the centre of the engine crank at the rear end of the crank-case. The engine was a 35 horsepower Vee design, water cooled, with overhead inlet and exhaust valves, and Bosch high-tension magneto ignition.
