ATTORNE Patented Aug. 24, 1937 2,091,091 INTERNAL COMBUSTION ENGINE William J. Borer, Tekamah, Nebr. Application September 23, 1936, Serial No. 162,200
4 Claims.
The invention relates to internal combustion engines and particularly to power take offs therefor wherein a crank is rotated by cylinder oscillated arms and has for its object to provide the crank with a shaft, which shaft is slidably mounted in a sleeve so that the shaft will take up the wear within the sleeve as the crank is rotated, said sleeve having pivotal connection to the oscillating arms.
A further object is to provide elongated apertures in the sleeve, through which the connecting portion of the crank extends out of engagement therewith.
A further object is to provide a link connection between the ends of the arms opposite the sleeve connection to the arms whereby a parallel movement is provided;
A further object is to provide cylinders arcuately shaped and in which pistons, carried by the ends of oscillating arms, are slidably mounted.
A further object is to provide means whereby a power take off to a crank is constructed in a manner whereby a slidable crank carried shaft is slidably mounted in a sleeve carried by a link connection between oscillating arms.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawing:
Figure 1 is a vertical longitudinal sectional view through the engine, showing the power take off applied thereto.
Figure 2 is a vertical transverse sectional View through the power take off and engine, the casing being eliminated for purposes of clearness.
Referring to the drawing, the numeral l designates the casing of the engine, which casing has disposed therein a plurality of arcuately shaped cylinders 2 in which are mounted arcuately shaped pistons 3. The pistons 3 are forced outwardly in cycles by explosive charges in the usual manner as well as inwardly for exhaust operation. The cylinder heads 4 are provided with exhaust ports 5 and intake ports 6 controlled in the usual manner through a cam shaft 1, cooperating with valves 8. Secured to the ends of the pistons 3 at 9 are the ends of the oscillating arms H], which are carried by spaced shafts I I, on which they oscillate.
It will be seen that as the pistons 3 are moved inwardly and outwardly in cycles, the arms l0 will be oscillated on the shafts II, and as the arms I0 are connected together at one of their ends by a link 12, and at their other ends by a link [3, there will be a parallel movement of the oscillating arms.
In devices of this character heretofore constructed, it has been the practice to slidably mount the crank pin M of the crank l5 carried by the driven shaft IS in an elongated slot in the link l3. This has caused so much friction and trouble in operation, the present device was designed to overcome the same. device the link I3 is provided with a sleeve II, in which is slidably mounted and guided a shaft Hi. The shaft I8 is provided with a bearing H! extending transversely therethrough, and in which the crank pin I4 is rockably mounted. As the crank I5 is rotated by the oscillation of the arms Ill, incident to the operation of the engine the shaft l8 moves upwardly and downwardly in the sleeve l1 and positively guides the crank pin [4 and reduces the friction to a minimum. The opposite sides of the sleeve H are provided with elongated openings 20 of greater width than the crank pin l4 so that the shaft l8 forms the sole In the present bearing connection between the sleeve I! and the crank pin I4.
It has been found that with a power take off as above set forth, the friction is reduced to a minimum and the power is positively applied to the pin l4 and that during the rotation of the crank, the shaft 18 allows side misalignment of the operating parts of the engine and the sleeve II in relation to the crank, thereby obviating binding of the driving parts.
From the above it will be seen that a power take off is provided which is simple in construction and one wherein a relatively long bearing drive is provided on the wrist pin, and that under all conditions of operation, the parts will adjust themselves for a uniform drive on the crank. As the arms III are oscillated they move in parallel relation and the crank is pushed around by this oscillating movement, and at the same time the slidable shaft l8 moves inwardly and outwardly for imparting the rotary movement to the driven shaft IS.
The invention having been set forth what is claimed as new and useful is:
1. The combination with an oscillating motor comprising spaced oscillating rocker arms, arcuate pistons carried by said rocker arms, said pistons extending into arcuate cylinders, means for moving the pistons inwardly and outwardly within the cylinders, of a power take off for said arms, said power take ofi comprising a link connecting the arms, a sleeve carried by the link, a shaft slidably mounted for inward and'outward movement in the sleeve, a crank pin rotatably mounted in a bearing of the slidable shaft, and a crank carried by said crank pin and rotated by the oscillation of the oscillating arms.
2- The combination with spaced oscillating arms of an internal combustion engine, a crank, a crank pin carried by said crank, of means for rotating said crank, said means comprising a link connection between the oscillating arms, an inwardly and outwardly movable shaft slidably mounted in the link connection, said crank pin being rotatably mounted in said inwardly and outwardly movable shaft.
3. The combination with an oscillating motor having spaced oscillating arms movable in parallel relation, link connections between the arms on opposite sides of the pivotal points thereof, a rotatable driven crank, a crank pin carried by said crank, of a power take ofi for said oscillating arms, said power take off comprising a sleeve carried by one of the links, a shaft slidably mounted in the sleeve and adapted to move inwardly and outwardly, said crank pin extending through the sleeve and having a bearing in the inwardly and outwardly movable shaft.
4. A device as set forth in claim 3 wherein the crank pin extends through elongated enlarged apertures in opposite sides of the sleeve and in spaced relation to the Walls of said elongated apertures.
