Not illustrated. 1903 edition. Excerpt: ...Spring and be sure they are all right? Is it desirable to open the deck and bulkhead to take out the tank and test it and the feed pipe under pressure? Hoping you will excuse this lengthy letter, Yours truly, "Auxiliary." We believe from "Auxiliary's" description of his installation that it is a good one though we could not give a final opinion without a personal inspection. The best way to test the connections in the spring Continued from p. 314.) In the design of the new portable engine the following principles are embodied: 1. An engine standing on an unfirm foundation must necessarily be different from the common stationary motors, even if it becomes more expensive to produce. It must be perfectly balanced in all directions in order to avoid the constant vibrations that "are so injurious for the engine. For this purpose the well known type having two pistons that work oppositely in one cylinder has been employed. Both pistons are connected to one double-throw crankshaft having its cranks set at 180 degrees, by a system of levers and rods. As all the parts when moving are always symmetrically distributed about the centerline, the center of gravity remains stationary and the vibrations are entirely prevented. 2. A portable engine which is intended for work in the open air and is exposed to all the vicissitudes of the weather should be well protected, especially the bearings and the sliding surfaces of the cylinder and piston must be kept free from dust and grit. At the same time, however, these parts should be easily accessible. This condition is fulfilled by the encased construction of the motor. 3. The portable engine should be comparatively small in weight in order to secure ease of transportation and more
