Applicatlonflled April 10, 1916. Serial No. 90328.

I To all whom it may concern: Be it known that I, JOHN 'HOULEHAN, a

citizen of the United States, residing at East Ely, in the county of White Pine and State of Nevada, have invented a new and useful Mechanical Movement, of which the following is a specification.

The device forming the subject matter of this application is an engine'and the invention aims to provide novel means whereby at each rotation of the shaft of the engine, two

strokes will be brought about ineach of two pitmen which form an operative'connectlon between the piston .of the engine and the shaft thereof.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above 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 etails of construction .hereinafterdescribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made with-.

in the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in top plan, an engineembodying the present invention, arts being broken away; Fig. 2 is a side e evation. of the structure shown in Fig. 1, the parts being in the posi-' grammatic view showing the parts in the positions which they .-will assume when asuction stroke is about to be made; Fig. 6 is a fragmental cross section showing portions of the disks, the engine shaft, one of the pitmen being shown in part; Fig. 7 is a diagrammatic view showing the device forming the subject matter 7 of thisapplication coupled up with a four-cylinder four-cycle engine; and is a diagrammatic view v Specification of Letters Patent; Patented men, 2%, fifiilfi.

showing the device forming the subject mat,

ter of this application coupled up with a two-cyhnder two-cycle engine.

vIn carrying out the present invention there is provided a base 1 supporting a bed 2 carrying a cylinder 3 in which works a piston 4. Upstanding from the base are standards 5 carryin bearings 6 in which is ournaled a shaft% provided with a fly wheel 8. Mounted on. and secured to the shaft 7 between the standards 5 is an intermediate disk 9. In one side of-the intermediate disk 9 there is fashioned a lenticular groove 25 comprising

branches

26 and 27 and provided at its ends with

seats

28 and 29. In the opposite side of the intermediate disk 9 there is formed a lenticular groove 30' comprising

branches

31 and 32, and having

seats

33 and 34 at its ends. The axes of the

grooves

30 and 25,- that is, the lines at right angles to each other. Secured to the shaft 7 isa disk 39. The disk 39 has upon lts inner face, a groove 40 shaped like which connect the pointed ends, are disposed the groove 25 in the intermediate disk 9, and alined therewith. Secured'tothe shaft 7 is a disk 41. In the inner face of the disk 41 there is agroove 42 shaped like the groove 30 inthe'intermediate disk and alined with the groove 30.

The numeral 35' designates a pitman carrying'a roller .38 adapted to" traverse the groove 25. The pitman; 35 carries also a roller v43adapted to traverse the groove 40.

\ 'At 36 there appears a pitinan provided with a a roller 37 adapted to traverse the groove 30, the pitman36 being equ1pped with a roller 44' adapted to. traverse the groove 45 to the piston 4. p

The disk and pitman constructlon hereinbefore described may be used upon an en ginevof any desired sort but in Figs. 1, 2, .3, 4

42. The

pitmen

36 and 35-.are pivoted asshown at and 5 a single-cylinder four-cycle internal j combustion engine has beenshown, by way of illustration'merely. When the structure is employed in connection withsingle-cylmder four-c cle internal combustion engine,

the operation is as follows the direction of the arrow A is about to be made, the rotating-in the direction of In Fig. 2, the parts are in the positions they assume when acompression stroke the arrow 0. During the compression stroke and while the disks are turning through an arc of 90, the roller pitman 36 is enand while the disks are turning through an arc of 90, the roller 38 on the end of the pitman 35 is engaged in the seat 29 of the groove 25, and the roller 37 onfthe end of the pitman 36 ridesin the branch 31 of the-groove toward the seat 33 of the groove 30.

In Fig. 4, the parts are. in the positions they assume when'a scouring stroke in the direction of the arrowA is about to be made, the disks rotating in the direction of the arrow G. During this stroke and while the disks are turning through an arc of 90, the roller 37 on the end of the pitman 36 is engaged in the seat 33 of the groove 30,

and the roller 38 on the end of the pitman 35 rides in the branch 26 of the groove 25 toward the seat 28 of the groove 25.

In Fig. 5, the parts are in the positions they assume when a suction stroke in the direction of the arrow B is about to be made,

the disks rotating in the direction of the arrow C. During the suction stroke and while the disks'are turning through an arc of 90, the roller 38 onthe end of the pitman 35 is engaged in the seat 28 of the groove 25, and the roller 37 on the end of the pitman 36 rides in the branch 32 of the groove 30 toward the seat 34 of the groove 30.

' It will be obvious that if the direction of rotation of 'theshaft 7 and th e disks is reversed, the operation above described will be changed somewhat. Further, the location of, theexhaust port and the timing of the inlet and exhaust valves, may alter the above described operation somewhat, but the operation above set forth is one which may take place and it will serve to illustrate one of the many operations which may occur.

The invention, of course, is not confined to be used in connection with an internal combustion engine, or with a single-cylinder four-cycle internal combustion engine of the sort above described.

In Fig. 7 of the drawings, there is shown diagrammatically, a four-cylinder four-cycle internal combustion engine, the cylinders of which appear at 46, the numeral 47 denoting the pistons. The pitmen are shown at 48 and the intermediate disks appear at 49, the same being constructed as hereinbefore described.

In Fig. 8 of the drawings, the numeral 50 designates the cylinders of a two-cycle twocylinder internal combustion engine, the pistons appearing at 51, the pitmen at 52 and 53, and the intermediate disks at 54, the same being of the sort hereinbefore set forth.

Having thus described the invention, what is claimed is 1. In an engine, a cylinder; a piston.

working in the cylinder; a disk supported for rotation and provided with lenticular guides, the axes of the angles to eachother; and pitmen, the inner ends of which are pivoted to the piston, the outer ends of which are provided with means for traversing the respective guides.

guides being at right 2. In an engine, a cylinder; a piston working in the cylinder; a disksupported for rotation and provided With lenticular. guides having seats at theirends, the axes of the guides being disposed at right angles to each
