INTERNAL COMBUSTION ENGINE Filed April 19, 1940 5Y4 vo/v. 5. BLE/VKEE INVENTOR A TTORNEK Patented Sept. 2, 1941 UNITED STATES PATENT OFFICE 2,254,817 INTERNAL COMBUSTION ENGINE Sylvon B. Blenker, Chicago, Ill. Application April 19, 1940, Serial No. 330,517

3 Claims.

This invention relates to an internal combustion engine and more particularly to such an engine wherein a pair of cylinders are positioned in parallel relationship with each other and in each of which is disposed a double headed piston capable of reciprocating movement.

The principal object of the invention is the provision of an internal combustion engine wherein parallel positioned double headed reciprocating pistons are connected at their centers by means of suitable connecting-rods so as to impart rotary movement to a crank shaft positioned centrally between the two parallel pistons.

A further object of the invention is the provision of an internal combustion engine of an extremely compact design which will produce an even power flow due to the rotary like application of power impulses to the crank shaft thereof.

Specifically, the internal combustion engine disclosed herein has as its principal point of novelty structure making possible the rotary like application of power impulses to the crank shaft thereof due to its unique utilization of crank shaft positioning in relation to the pistons and cylinders thereof.

With. the foregoing and other objects in view which will appear as the description proceeds,

the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation with parts in cross section showing in detail the reciprocating double headed pistons and the crank shaft and connecting rods in connection therewith.

Figure 2 is a cross sectional view taken on lines 22 of Figure 1 and shows in detail the crank shaft of the engine in relation to the pistons and known to the art. The motor block Ill is provided with a head II at each end thereof which heads incorporate intake and exhaust ports I! and I3 which are controlled by valves IZA. and HA. The block ill is so formed so as to provide a pair of parallel positioned cylinders l4 surrounded by suitable water Jackets I 5. Slidably positioned in each of the cylinders I4 there is a double headed piston I6 each of which is provided with a plurality of suitable rings adjacent each of the head portions thereof so that combustion taking place in the cylinders l4 adjacent the heads of the pistons [6 will serve to impart reciprocating movement thereto.

For purposes of simplicity only the portions of the internal combustion engine incorporating novel structure have been illustrated as the timing and the carburation mechanisms of this internal combustion engine may be essentially the same as that of any double action motor known to the art.

In order that the reciprocating movement of the pistons l6 may be most usefully employed, connecting rods i I are attached to centrally positioned wrist pins is in each of the pistons l6 and to adjacent appropriately shaped sections of a crank shaft l9 which is centrally positioned between the pistons l6 and at right angles thereto. It will thus be seen that reciprocating action of the pistons [6 will continuously impart rotary like power impulses to the crank shaft I9 the net result of which will be a more uniform flow of power to the crank shaft and a more eiiicient useful action on the part of the internal combustion engine. By referring to Figure 2 of the drawing wherein a fragmentary view is shown, it will be seen that the crank shaft is supported in suitable bearings 20 and that the pistons and cylinders l6 and It, respectively, while positioned in parallel relation to one another are not positioned in comparable planes which makes possible the application of their power impulses to the crank shaft l9 as shown. Referring again to the drawing it will be obvious that suitable bushlugs and bearings may be employed in connection with the connecting rods I! and their connections with the wrist pins l8 in the pistons l6 and the crank shaft Hi. It will thus be seen that an internal combustion engine incorporating a practical mode of operation resulting in a rotary like application of power impulses to a centrally positioned crank shaft has been disclosed some of the various advantages of which are obvious. For example, the normal piston and cylinder wear is greatly reduced in that the pistons are supported uniformly at their respective ends thus preventing any tendency toward wobbling which would result in uneven wear of the cylinder surfaces.

Further, the problem of lubrication is simplified cation thereby made available. It is also obvious that suitable timing and carburation may be readily incorporated which will result in a complete internal combustion engine of considerably greater efficiency than has heretofore been known to the art particularly with respect to the rotary like application of power impulses to the crank shaft portion thereof.

What I claim is:

1. An intemai combustion engine characterized by the incorporation of adjacently positioned double headed cylinders on different planes, a double headed piston slidably positioned in each of the said double headed cylinders, wrist pins positioned centrally in each of the .said pistons, together with openings in the said pistons adapted to provide for the positioning therethrough of connecting rods, said connecting rods establishing connection with a crank shaft centrally positioned in relation to the said pistons and at right angles thereto so that reciprocating movement of the said pistons results in the rotation of the said crank shaft substantially as described.

2. An internal combustion engine including a pair of spaced parallel cylinders, a piston reciprocally mounted in each of the said cylinders, slots in each of the said pistons, the said pistons adapted to receive power impulses at the opposite ends thereof, a crank shaft disposed between the said cylinders at right angles thereto, connecting rods attached to the said cranks of the said crank shaft and to the said pistons and functioning through slots formed therein and secured to the said pistons by wrist pins substantially as described.

3. An internal combustion engine including a cylinder block having a plurality of parallel cylinders spaced apart, a crank shaft iournaled in said block between and disposed at right angles to the axis of the said cylinders, cranks formed in the said crank shaft opposite the said cylinders. a piston reciprocally mounted in each of the said cylinders and having longitudinally disposed openings therein providing for the entrance thereinto of a piston rod, said rod secured to the said piston at a central location and to the cranks in a conventional manner, whereby at each movement of the said pistons said connecting rods will move the said cranks of the said crank shaft with a rotary action.
