Patented Nov. 1 1, 1913.
Application filed April 4, 1918. Serial No. 758,968.
To all wkomz't may concern:
Be it known that I, J OHN JAMES MOLEAN, a subject of the King of, Great Britain, residing at Moose Jaw, in the Province of Saskatchewan, in the Dominion of Canada, have invented certain new and useful Improvements in Internal Combustion Engines, and do hereby declare that the following is a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in internal combustion engines and the objects of the invention are to increase the amount of power obtainable from each cylinder of the engine, to reduce the number of working parts, to generally improve and simplify the construct1on of the various parts to better adapt them to perform the functions required of them.
It consists essentially of the improved construction hereinafter described in detail in the accompanying specifications and drawm s.
Tn the drawings: Figure 1 is a plan view of the engine. Fig. 2 is a vertical section through one of the cylinders. Fig. 3 is a perspective detail showing the connection to the pumping mechanism. Fig. lis a sectional detail through one of the pumps feeding the combustible. Fig. 5 is a detail showing the igniting means.
In the drawlngs like characters of reference indicate corresponding parts in all the figures.
Referring to the drawing, A represents the cylinders of the engine, of which any number may be provided and which are preferably disposed horizontally. In accordance with the present invention, each cylinder is open at both ends and pistons C and D are provided in the ends, each piston working from the center to opposite ends andbeing connected to separate crank shafts E andkF or equivalent rotary mechanism, located opposite the open ends of the cylinder, said crank shafts being supported in suitable bearings G and H which rest on the base K. Links 10 connect the pistons with the crank shafts. Fly wheels L may be provid'ed on the end of the crank shaft.
Combustible is introduced in the center of the cylinders in any suitable way. I have illustrated the pump M of any suitable construction adapted to feed the combustible, which may be a mixture of gasolene-and air, through the inlet ports N, the said pump being conveniently operated from a link 12 which connects cranks 13 and 143on opposite crank shafts and is connected to the pump piston 15 by means of a bent arm 16 having a slot-17 which fits over a pin 18 on the link 12. The exhaust gases may pass simultaneously out both ends through exhaust ports 17 and 18. The passage of thecombustible fluid into the pump is controlled by a suitable check valve 22.
The spark plugs 20 may be controlled by suitable means. I have illustrated a pivoted insulated lever 40 pivoted to a bracket 41 on the cylinder and the lower end 42 of which is adapted-to be engaged by the con-v necting rod 12 when raised, the inner end of the lever being adapted to make a circuit through a flexible contact finger 43.
The cycle of operation of the engine will be readily understood.
The combustible gas is forced into the cyl- I inder under moderate pressure when the pistons are near the center. Ignition is caused to take place through suitable spark plugs 20 and the pistons are driven by the expansion in opposite directions, thus utilizing the expansion in both directions of the gases and thereby securing greater economy.
It will be seen that the engine takes up very little room owing to the reduction of the number of working parts. The two crank shafts perform separate work or may be geared together,
As many changes could be made in the above construction and many apparently widely difl'erent embodiments of my invention, within the scope of the claim, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the specification and drawing shall be interpreted asillustrative and not in a limiting sense.
What I claim as my invention is: the link and feeding pumps operatively con- An internal combustion engine comprising nected to the link. 10 cylinders open at both ends, two pistons in In witness whereof I have hereunto set each of the cylinders movable from the cenmy hand in the presence of two witnesses.
5 ter to opposite ends, two crank shafts, rods JOHN JAMES MGLEAN.
