To all whom it may concern:
Be it known that I, OLAND Moonn, a
citizen of the United States, residing at Bethel, in the county of Shelby and State of Missouri, have invented new. and useful Improvements in Engines, .of which the following is a specification. p
This invention relates to improvements 1n engines and particularly to means for transferring power from the engine piston to the' drive shaft and is especially designed for use in connection with internal combustion engines.
An object of the present invention is to dispense with the usual crank shaft and to substitute therefor a connection in the nature of an elliptical plate secured to a straight drive shaft. o
A further object is the provisionof means for connecting more than one piston at the same point to the drive shaft, to provide for economy of space and to further increase the power-of the shaft.
Other objects and advantages of the invention will appear as thefollowing description is read in connection with the accompanying drawings.
In the drawings:
Figure 1 is a side elevation of an engine, embodying the present invention.
Figure 2 is a longitudinal sectional view taken on a, line with the drive shaft.
Figure 3' is a transverse sectional view.
Figure 4 is an enlarged detail section taken on a line with the sliding bearing-for the piston rod.
Figure 5 is an enlarged section through one of the forked ends of the piston rod,- the figure being taken at right angles to Figure 4.
Figure dis a detail view of the segmental wear plate for the sliding bearing.
, Referring in detail to the drawings, 'whereimlike characters of reference denote corresponding parts, the reference character 10 indicates the engine base, upon which are mounted cylinders 11. These cylinders are arranged in pairs side by side, and maybe formed in a double block with threescylinders in;e'ach block, providing a six cylinder engine. Of course it is understood that the number of cylinders may vary as desired. The'base comprises a plurality of trans- -versely disposed bars 12, which are spaced apart and have their ends connected by side plates 13. Depending from the bottom of grees with respect to one another. upon their opposite side edges and extend the base and connected to the side plates between each of the bars 12 is a wheel or disk 17 Various means may be employed for securing the wheel or disk to the shaft, one of said means b'e'ingp'rovided by threading the shaft and the bore of the wheel or disk 17 and screwing the latter in position, the said threads being of a greater diameter than the diameter of the shaft and extending only a sufficient distance to permit of the proper adjustment of the wheel or disk. The shaft is grooved transversely of the threads as indicatedat 18 and keys 19 are inserted in these grooves and in grooves provided in the wheel or disk, so that rotation of the latter with respect to the shaft is prevented. Collars or nuts 20 are then screwed into position upon the opposite sides of the wheel or disk against the end of the keys 19 to prevent the accidental removal of the keys.
The wheels or disks 17 are of elliptical shape and are arranged upon the shaft at approximately a hundred and twenty de- Secured ing around their periphery are plates 21. These plates are provided with grooves 22 which are disposed adjacent the periphery of the disks and are bolted thereto by means of bolts 23, which pass through the plates and disks. In addition, the plates are provided with flanges 24 which extend-over the periphery of the disk and to which they-are secured.
I The disks 17 are designed to take the place of the usual cranks of the drive shaft of the engine and for this purpose they have aworking connection with a piston rod 26, Y
which is 1n turn connected to the piston 27 of each of the cylinders 11, as is usual in englnes of thlstype. For this purpose, each of the rods 26 are forked at one end as indicated at 28 and each end of the fork is provided with a double bearing 29. These bearings are designed to receive balls 30, which project beyond the ends of the bear.-
ings, the opposed ballsof each fork engag-.
ing and traveling in the grooves 22 of the disks.- The opposite or outwardly extendend of the piston rod, the latter being designed to reciprocate in this groove or sliding bearing, due to the movement of the pistons. This reciprocation causes a, rotation of the disks 17 due to the engagement of the forked end of the connecting rod with the grooves 22. Any suitable connection between the piston rod and the piston may be provided, such as is indicated at 32.
By providingthe plate 21, the bearing between the connecting rod and the disks may be renewed when necessary, and in order to provide for the renewal of the sliding bearings 31, each of the bars 12 are provided upon opposite sides with counter sunk plates 33, flush with the surface of the bars.
These plates are of segmental formation and a are shaped to conform to the groove 31, be-
mg bolted in position by means of the bolts 34:. a
The upper edges of the bars 12 are beveled as shown and the cylinders are arranged at an inclination with respect to the vertical and a sliding bearing 31 is provided adjacent each end of said bars. By this means two connecting rods may be engaged with'each of the disks 17, so that each disk will be acted upon by a pair of pistons.
The. invention is susceptible of various changes in its form, proportions and minor details of construction, and the rightis herein reserved to make such changes as properly fall within the scope of the appended claim.
Having described the invention What is claimed is The combination with an engine including pistons; piston connecting rods and a drive shaft, of a plurality of spaced transversely disposed bars, bearings secured to said bars and being adapted to receive the drive shaft, a counter sunk plate secured upon each side of the bars and being provided with a groove, an elliptical shaped disk disposed between each pair of bars and being detachably secured to the drive shaft, plates secured to the opposed side edges of the disks and being designed to extend around the periphery thereof, and there being a groove disposed adjacent the periphery thereof, a
forked end for each connecting rod, and
anti-frictional elements "carried on each side of each fork, the inner anti-friction elements engaging the" grooves of the plates on the disks and the outer anti-friction elements engaging the groove of the countersunk plates, as and for the purpose-speci- In testimony whereof I aflix my signature.
