Galloways non dead centre engine was an attempt to build an engine with the advantages of self starting in any position with the simplicity of a single crank.as canbe seen there are two vertical cylinders connected by a connecting rod of triangular configuration to a singlecrank placed between the cylinders.as the pistons are 90 degrees out of phase to each other there is never a position where the piston of at least one cylinder cannot bear upon the crank.during each revolution the top beam of the connecting rod goes from horizontal to an angle as the piston rods are in a fixed plane some means of extending the beam is required. this is accomplished by having sliding bearings in the crossheads.to keep the centre of the connecting rod beam in a straight vertical line,a motion beam is connected to the centre of the connecting rod beam and goes via another sliding bearing housed in brackets to the side of one cylinder to another tie rod which goes back to the brackets. this sort of \\\"parallel motion\\\" constrains the connecting rod into astraight vertical line.having a lever going up and down to the side of the engine it was convenient place to put an air pump driven by said beam.would be willing to part ex for built or part built loco or traction engine. ....
