E. WERCELY. INTERNAL COMBUSTION ENGINE Filed June 1926 INVENTOR ATTORNEY Patented Feb. 1, 1927.
UNITED STATES PATENT OF FICE.
ELIC WERCELY, OF MASON CITY, IOWA.
mrnrman-comnusrron ENGINE.
Application filed June 22,
The invention primarily has for its object to provide a new and improved internal combustion engine structure capable of producing relatively more power than common types of engines and which is simply and economically constructed and so arranged and balanced as to be substantially vibrationless.
In its more detailed nature the invention seeks to provide a new and improved internal combustion engine of the four-cycle type wherein two pistons work in opposition in a single cylinder, the explosion taking place between them, and the said pistons are bell crank lever and link arm connected to a single double throw crank, providing for economy of manufacture, relative power increase, elimination of vibration and a better balance of operation than is possible in common known types of such engines.
lVith the above and other objects in view that will hereinafter appear, the invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described, then be particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which:
' Figure 1 is a diagrammatic longitudinal section illustrating a single cylinder ar-' rangement embodying the invention, the parts being at the position for starting the compression stroke.
Figure 2 is a-view similar to Figure 1 illustrating the parts at the position for starting the explosion or power stroke.
Figure 3 is aplan view illustrating the positioning of the levers and link arms which connect the shaft.
In the drawing I have illustrated diagrammatically the application of my invention in connection with a single engine cylinder.
In the drawing, in which like numerals of reference indicate like parts in all of the figures, 1 indicates the cylinder which is in the nature of an open ended cylindrical body suitably constructed. Any approved type of sparking device is diagrammatically indicated at 2 and intake and exhaust valves are likewise indicated by the numerals 3 and 4:.
A single crank shaft 5 is provided and is preferably positioned centrally of and pistons with the crank 1926. Serial No. 117,767.
beneath the cylinder and is equipped with double cranks 6 and 7 bearing the angular relation, as indicated.
One of the cranks 6 is link-arm connected as at 8, to the short arm of a bell crank lever 9 pivoted at 10, in any suitable manner beneath one end of the cylinder.
The long arm of the bell crank lever is link-arm connected as atll with the piston 12 reciprocable in that end of the cylinder beneath which the bell crank 9 is mounted.
Another piston 13 is reciprocable in the other end of the cylinder 1, the said pistons 12 and 13 operating in opposition so that that the explosion taking place between the pistons when they are at their central position, as illustrated in Figure 3 of the drawing, will cause them to travel outwardly in the cylinder in unison.
The piston 13 is link-arm connected as at 14 to'the long arm of a bell crank lever 15 pivoted as at 16 in any suitable manner he neath that end of the cylinder 1 in which the said piston reciprocates.
The short arm of the bell crank 15 is linkarm connected as at 17 to the crank 7.
It will be observed that the lever and link connections for connecting the piston in one end of the cylinder with its respective crank is an exact duplicate of the similar mechanism by which power is applied from the other piston to its respective crank.
As shown in Figure 5 of the drawing the link arms 8 and 17 may be offset as at 18 so that the link arms and bell crank levers may operate in the same central plane, thus tending to reduce to the minimum all tendency to vibrate.
By providing two pistons operable in opposition to each other in a single cylinder, it
is possible to provide amore perfectly balanced engine and one in which a maximum advantage of explosive force is obtained. This arrangement also tends to eliminate viblation and in conjunction with the bell crank lever and link arm method of transmitting the motion from the pistons to the crank shaft a relatively greater amount of power is produced than'is possible in the common types of engine. The peculiar arrangement of levers and link arms, together with the piston arrangement, also provides for applying the power to the crank shaft by a double pull action exerted always from two points simultaneously tending toward a more smoothly running engine in which the power impulses are more smoothly distributed than is commonly the case.
From the foregoing description, taken in connection With the accompanying drawing, it is thought the novel details of construction, manner of operation and advantages of my invention will be readily apparent to those skilled in the art to which my invention relates.
What I claim is: i
1. In an engine of the class described, an open ended cylinder, a pair of pistons oppositely reciproeable in the cylinder whereby to provide an explosion chamber between them and substantially centrally of the cylinder ends, a crank shaft positioned centrally beneath and transversely of the cylinder and having a double crank, a bell crank lever pivotally mounted beneath each cylinder end and each having a long and a short arm,
a link arm connecting each bell crank lever long arm to one piston, and a link arm connecting each bell crank lever short arm to one crank portion of the double crank.
2. In an engine of the class described, an open ended cylinder, a pair of pistons oppositely reciprocable in the cylinder whereby to provide an explosion chamber between them and substantially centrally of the cylinder ends, a crank shaft positioned centrally beneath and transversely of the cylinder and having a double crank, a bell crank lever pivotally mounted beneath each cylinder end, and each having a long and a short arm, a link arm connecting each bell crank lever long arm to one piston, and a link arm connecting each bell crank lever short arm to one crank portion of the double crank, said pistons, said bell crank levers and said link arms being positioned to operate in a common plane.
