Abstract
A engine imparts rotary motion to a pair of flywheels.
The engine has a pair of axially aligned opposed cylinders. A
piston is mounted for reciprocation in each said cylinder and a drive shaft is connected to each piston. The pistons cause the drive shaft to reciprocate. A connecting rod is mounted for rotation to each flywheel and to the drive shaft. As the drive shaft reciprocates so too does the connecting rod with resulting rotation of the flywheels.

Description
BACKGROUND OF THE INVENTION
This invention relates to engines for driving a pair of flywheels and more particularly to an engine having a drive shaft which is caused to reciprocate by a pair of piston cylinders and which in turn imparts rotary motion to a pair of flywheels.
Engines are known having one or more pairs of opposed piston cylinders which cause a drive shaft to reciprocate.
Such engines usually include crank shafts, crank cases and transmissions. Examples of such engines are described in the following patents of the United States: no. 4,485,768 to Heniges; no. 4,715,336 to Schindler et al; no. 3,195,420 to Johanssen; no. 2,489,068 to Carlson; and no. 2,439,867 to Schaeffer.
It has been found that engines having pairs of opposed piston cylinders can be used to drive pairs of flywheels. Such engines do not require crank shafts to do so. The flywheels are particularly suitable for driving such things as twin marine screws but are suitable for other uses where two separate sources of driving power are required.
SUMMARY OF THE INVENTION
The engine of the invention imparts rotary motion to a pair of flywheels and includes a pair of axially aligned opposed cylinders. A piston is mounted for reciprocation in each cylinder. A drive shaft is connected to both pistons and is caused to reciprocate by them. A connecting rod is rotat-ably connected to each flywheel and is rotatably connected to the drive shaft such that reciprocation of the drive shaft causes a like reciprocation of the connecting rod with resulting rotation of the flywheels.

DESCRIPTION OF PREFERRED EMBODIMENTS
With reference to Figures 1, 2 and 3 the engine of the invention, indicated generally 10, includes an internal combustion engine of the type having a pair of horizontally disposed cylinders 12, 14 both mounted within a housing 16.
The cylinders are disposed in axial alignment and are positioned on opposite sides of a drive shaft 18. Since such engines are well known and are described in a number of U.S.
patents including those referred to above, a detailed description is deemed unnecessary.
The cylinders are provided with the usual supply of fuel and means for discharge of exhaust gases. The combustible mixture in the cylinders is ignited by spark plugs 20, 22 from any conventional type of ignition system (not illustrated).
Mounted for reciprocation within the cylinders are pistons 24, 26. The pistons are fixed to drive shaft 18 and cause the shaft to reciprocate in the direction of arrow 28.
The shaft is rotatably attached at 29 to a connecting rod 30.
~181098 With reference to Figures 2 and 3, pins 32, 34 extend outwardly from rod 30 adjacent to each of its ends and those pins are mounted for rotation to flywheels 36, 37. The flywheels in turn are keyed to axles 38, 39 which are mounted to bearings in vertical supports 40, 41.
With reference to Figure 6, 7 and 8 pins 45, 47 are fixed to opposite ends of connecting rod 49. Pin 45 is mounted for rotation to one end of link 51 and pin 47 is similarly mounted to an end of link 52. An axle 55 is fixed to the end of link 51 opposite pin 45 and flywheel 57 is keyed for rotation to that axle. Similarly an axle 59 is mounted to the opposite end of link 52 and flywheel 60 is keyed for rotation to that axle.
Axles 55, 59 are mounted in bearings in supports 61, 63.
The engine illustrated in Figures 1 - 5 operates as follows: The reciprocating pistons rods 24, 26 cause drive shaft 18 to reciprocate and that reciprocation is imparted to connecting rod 30. As the rod reciprocates, it causes the flywheels 36, 37 to rotate in opposite directions as illustrated in Figure 3.
The engine illustrated in Figures 6 - 8 operates in a similar manner. Connecting rod 49 will cause links 51, 52 to reciprocate and that reciprocation is translated into rotary motion as the links cause the flywheels 57, 60 to rotate. As illustrated in Figure 7, pin 45 is located at a point on link 51 which is spaced equidistantly from axle 55 as the spacing of pin 47 from axle 59. The point of pin 45 on flywheel 57 is diametrically opposite that of pin 47 on flywheel 60.
It will be understood of course that modifications can be made in the preferred embodiments illustrated and described herein without departing from the scope and purview of the invention as defined in the appended claims.
