Piston Pump, Liquid Fuel Rocket, R.H. Goddard

Rod, brass, that bends or slopes upward, in a wide "J" pattern, with smaller diameter, very short extension of horizontal pipe projecting from curved elbow of the "J"; smaller pipe with a flange on end, from which is projected a much thinner, stick-like rod or wire; this thinner rod not entirely straight but bended; this rod also moveable (i.e. can be depressed), with tiny piston at opposite end, within larger pipe, so that the whole serves as a piston pump; flange, from which the thinner (piston) rod is attached, is a two-sided fixture, each side with small, equidistant set of four holes, in square pattern.
