Not illustrated. 1902 edition. Excerpt: ... the bottom, so that any oil thrown against the sides will drain quickly and not be taken up with the next suction. Sometimes, when the exhaust pipe is long and the speed high, the quick opening of the exhaust valve and the inertia of the gases in-the long pipe causes a slight vacuum in the cylinder and the admission valve is opened sharply for an instant. This disturbs the falling stream in the vaporizer, throws it against the sides, and carries some of the oil up around the valve casings, where it is taken up by the regular suction of the admission stroke just as it is beginning to drain back to the overflow pipe. By correct design and proportion these things can be wholly overcome; only no general rules will apply to different forms. The gasoline pump can be easily made by drilling out a brass rod for a small rod plunger and fitting a stuffing box to the end. The packing used should be asbestos wicking and there should be small rings of hemp on each side of the asbestos; for, while asbestos will hold gasoline from leaking, it will not stay in place, but will work back into the pump and out around the stuffing box, unless held in place. A pump packed this way will not leak a drop. The valves can be made very efficient in a simple way. If the pump is for J4-inch pipe, use a J-inch brass rod, and attach it to the pump barrel. Drill a J4-inch hole clear through and counterbore with a 15-32-inch drill about 1 inch deep. This is threaded for 4-inch pipe and a Jjj-inch bicycle ball dropped in. Striking this ball down against the bottom of the counterbore with a punch and mallet completes the check valve; the hardened ball seats itself perfectly in the softer brass. This also, hardens the brass seat slightly. If it ever needs regrinding simply more
