INTERNAL coMBus rIon Application filed October 22, 1927, Serial R0. 228,028, Renewed. April 7,

This invention relates to internal combustion engines and it is an object of the invention to provide a driving connection between the pistons and crank shaft through the medium of a turning cross head constructed and assembled in a manner to substantially eliminate the liability or" dead center and which assures maximum of eliiciency of each of the pistons throughout the entire stroke thereof.

It is also an object of the invention to pro vide a motor of this kind wherein is avoided piston slam against the walls of the cylinders with a resultant elimination of vibration and a material reduction in wear of the pistons and cylinders.

Another object of the invention is to provide a motor constructed in a manner whereby substantially twice the power is obtained with substantially the same amount of fuel as required by internal combustion engines now generally in use.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved internal combustion engine whereby certain important advantages are attained. and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein 7 Figure 1 is a fragmentary view partly in vertical section and partly in elevation illustrating an internal combustion engine constructed in accordance with an embodiment of my invention;

Figure 2 is a view partly in elevation and partly in section of the structure as illustrated in Figure 1 at substantially a quarter turn with respect thereto; and Figure 3 is a view in top plan of the cross head unapplied.

As disclosed in the accompanying draw ings, B denotes an engine block provided with the cylinders 1 in each of which is arranged a piston 2.- Each ot the pistons 2 has pivotally engaged therewith, as at 3 an end portion of a piston rod 4. This, piston rod elis disposed toward the open end of the cylinder 1 and is hingedly connected, as at 5, with a-turning crosshead C. i i

r The cross head G comprises a castbocly member 6, the central portion ofwhich being provided with an upstanding arm 8- extendljngthereacross through the upper portion of which is directed a supporting rod 9. The extremities of the rod- 9 are engaged within the blocks 10 carried by thesid'e walls 11 or the casing. The corner portions of the member 6 are provided with the upstanding arms 12 to the upper end portions of which are pivotally connected at 5 as hereinbefore referred to the lower or outer extremitiesof the piston rods 1 coacting with thepist'ons2 working within a pair of transversely aligned cylinders 1.

' The body member 6 of the turning cross' head C at one end thereof is providedwith a pair of depending and transversely aligned bearing lugs 15 in which are keyed the extremitles of a shaft 16. Operatively engaged with the shaft 16. is an end portion of apitman 17 the opposite end'por'tio'n'of said pitman 17 being operatively engaged, as at'lS, with a cranl; 19 of a crank shaft'2Q. The end portion of the member 6 of the turning cross head 0 remote from the depending 111g 15 is provided with a weight 14'to assure desired balance of the cross head C.

The block B supports a pair of cam shafts 21 coacting with the rods 22 for operating in proper sequence the rocker arms 23 of the cylinder valves. The shafts 21 are in driven connection through the medium of the intermeshing gears 24and one of said shafts is in ion driyen connection through the medium of the chain 25 or the like with the crank shaft 20.

In the accompanying drawings, the pistons 2 are disclosed as midway their strokes and it is to be understood that a pair of transversel to aligned pistons operate in unison, thus e fecting requisite turning or swinging movement of the cross head C which, through the medium of the pitman 17, rotates the shaft 20. This mechanism is such as to eliminate dead J00 center and is one wherein full power is obtained during an entire stroke, thus eliminating vibration.

It is also to be noted that the structure as hereinbefore described, is such to assure the pistons 2 traveling at all times along a perpendicular path, avoiding all piston slam and minimizing wear.

,From the foregoing description it is thought to be obvious that an internal combustion engine constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not Wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim In combination with a pair of vertically disposed cylinders, pistons working therein, a connecting rod pivotally connected to each of said pistons and depending therefrom, a cross head mounted between the cylinders and within the crankcase, said cross head comprising a body portion, a central upstanding lug, a lug at the opposite end portions of said body member, and a weight secured to said body member for balancing the same, said central lug being pivotally mounted between the cylinders, and said end lugs being pivotally secured to the lower end portions of said connecting rods, a pair of depending lugs secured to said body portion of said cross head at a point spaced inwardly from one end thereof, a pitman, a crankshaft, said pitman being pivotally mounted at one end to said depending lugs and at the opposite end to said crankshaft, a plurality of valves for each cylinder, and means for operating said valves cooperatively with the turning of the crankshaft.

In testimony whereof I hereunto afiix my signature.

HARRY L. KLINE.
