,Each compression cylinder contains a cylinder the same being designated A, B, C and respectively. These are mounted for a rectilinear or back and forth movement. in their respective compression cylinders,-and the working cylinders in turn contain working pistons A, B, C and D", said istons having their respective rods direct y connected to the wrist pins 13 of a crank shaft 14, the cranks of said shaft being set at 180 degrees apart and the shaft 14 being j ournaled eccentrically in the hollow bearin or supports 3.: 1 5 desiglugs or charge i'gnlting devices of .which t ere is one for each of the working cylinders, mounted in the outer end ways for crosshea thereof, t e p ugs being designed to close the charge igniting circuits at'the terminals 16, upon the completion of the outward traverse or. stroke of the working cylinders. And .17 designates the automatically acting valves for the working cylinders, said valves being mounted in the outer ends'thereof and controlling the communication between the interior of-the [working cylinders and the interior of the compression cylinders.

pairs with" their Itis also to be particularly noted that the pistons operate in working cylinders that are in turn mounted in chargerom ression cylinders for relatively long1tudina movement therein coincident with, but at a slower rate of speed than, the said pistons, whereby the friction of thepistons 1s materially reduced; and, what is more important, such arrangement provides that t e explosive charge will drive the pistons and (through them) the shaft with an expansion chamber less than the displacement of the piston, owing to the follow1ng-up movement of the working cylinders as the pistons travel forwardly. Conversely, the amount of the ex- )losive mixture taken into the working cylinders can be, if desired, several times greater than the displacement of the. pistons. Also, the force of the explosions at one-half stroke is exactly tan ential to the throw of the crank, thereby o tainingmaximum efii-' ciencywith a relatively short stroke, and, as above noted, with an expansion chamber less than the displacement of the piston.
