Application filed Gctober 26, 1915.
To all whom it may concern I Be it known that I, RICHARD M. DAY, a citizen of the United States of America, residing at Hudson, in the county of Lincoln and btate of South Dakota, have invented certain new and useful Improvements in InternaLCombustion Engines, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to internal combustion engines and has for its object the pro duction of a simple and efficient means for actuating the control valves for regulating the inlet and exhaust of the gases to and from the explosion cylinders.
Another object of this invention is the production of a simple and eflicient combustion engine consisting of a minimum number of parts which to install and maintain.
With these and other-objects in view, this invention consistsof certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.
In the accompanying drawings Figure 1 is a central longitudinal section through one of the cylinders.
Fig. 2 is a top plan view of the base for supporting the explosion cylinders.
Fig. 3 is a central transverse sectional view through the cylinders.
Fig. 4 is a. central transverse section taken through the piston rod.
Fig. 5,is a. central longitudinal section through one of the pistons. 1
Fig. 6 is a vertical section through a portion of one of the cylinders, showing the manner in which the gases ar admitted or conveyed to the explosion cylinders. Fig. 7. is an enlarged vertical section through the lower end of one of the valve stem supporting shoes.
Fig. 8 is a detailed perspective of one of the cam supporting rods.
Referring to the accompanying drawings by numerals it will be seen that 1 designates the base of'the device which supports the explosion cylinders 2 and this base 1 is provided with projecting portions 3 for sup-- porting the crank shaft 4.. This'crank shaft etcarrics a fly-wheel 5 and is journaled upon the journal portion 6 of the bracket portions 3. A piston rod 7 'isconnected to the crank shaft 4 and this crank shaft 4 also carries a sprocket Wheel 8 over which a chain 9 Specification of Letters Patent.

passes, the chain sprocket wheel 10 driving shaft 11.
The auxiliary driving shaft 11 carries a pair of beveled gears 1.2 which beveled gears 12 mesh. with the beveled gears 13 carried by the cam-supporting rods 14. One of these rods 14 extends along each side of the base 1 as illustrated in 2 of the drawings.
These cam-su 'iporting rods lt carry valve actuating cams 15 which cams 15 are arranged in pairs adjacent the respective ends of the rods 1.4:. The cams 15 are adapted to engage the spring-pressed jaws 16 carried by the valve stems 17. through the depending portions 18 of the in turn passing over the armed by the auxiliary The valve stems 17 work v mounted upon each depending portion 18 for normally urging a downward pressure upon the flange portion 21 of the jaw 16, the jaw being secured to the stem 17 by means of a pin 22. The jaw 16 is provided with a reduced neck 23, which neck is slidably mounted in the socket 24 of the depending portion 18 of the cylinder head 19 so as to have a frce'upward and downward movement for actuating the valves 25 carried by the valve stems 17;
It should he understood that the valves 25 are preferably arranged in pairs Within the cylinder heads 19 and the cams'15 of each pair are arranged so as to alternately open and close the respective valves 25 carried by the cylinder heads 19.
Each cylinder head 19 is provided with the. usual water jacket 26 andcarries a spark plug 27 which is connected in any suitable or desired manner to a source of electrical supply and igniting mechanism for igniting the charge within the cylinder 28. The cylinder 28 is also provided with a water jacket 29 having a discharge aperture 30 for connecting thesiphon wherebythe supjackets 26 and 29 .As illustrated clearly in Fig. ,3, the piston rod 7 works between the cylinders 28, which cylinders 28" area'rranged so as to extend in parallel relation with respect to each other. The spools 33 are supported upon a connecting rod 35, which connecting rod is secured to the opposite pistons working in the oppositely disposed cylinders 28.
It should be understood that a c linder head 19- is-carried by each end oi: the cylinder 28 and these heads are constructed similarly to each other and are provided with inlet and exhaust valves of the same construction as that previously described,
which valves are actuated by one pair of the cams carried by the rods 14.
An inlet pipe 36 is connected to the channel 37 formed in the outercasing of the cylinder 28 and this channel 37 communicates with the passageways 38 formed in the cylinder 28, which passageways 38 communicate with the inlet ports 39. The inlet port 39is controlled by means of the valve 25, actuated as above described.
Each cylinder head 19 is provided Withan exhaust port 40, controlled by one of the valves 25.
The base 1 is provided with a cradle 1 into which is'seated the depending base 2 of the cylinders 28.
From the foregoing description it Will be seen that a very simple and eliicient valve actuating means has been produced for controlling the opening and closing of the valves for permitting the inlet gases and exhaust gases to be readily admitted to or discharged from the explosive cylinder, the explosion of thedevice taking place at alternate times at the opposite ends of the cylinder 28. 4
What I claim is 1. An engine of the class described comprising a base, a plurality of explosion cylinders arranged in parallel relation, a piston working in each cylinder, each piston comprising a pair .of piston heads, a plurality of converging arms connecting the respective heads of each piston, said arms provided with a socket near the junction thereof, a spool seated within said socket and fixedly secured thereto, a crank pin inserted through said spool and through the junctions of said,
arms, said spool constituting a bearing for said crank pin, each cylinder provided with a. longitudinally extending elongated slot, said slot constituting a guide to said spool for permitting the reciprocation of said pistons within said cylinder, and a crankarm for operating said crank pin.
2. An engine of the class described comprising a base, a plurality of explosion cylinders arranged in parallel relation, a piston working in each cylinder, each piston comprising a pair oi piston heads,.arms connecting the respective heads of each piston, a spool carried by said arms, a crank pin passing through said spool, said spool constituting a bearing for said crank pin, each cylinder provided with a longitudinally extending slot, said slot constituting a guide for said spool and permitting the reciprocation of said pistons within said cylinder and means for operating said crank pin.
in testimony whereof I hereunto afiix my signature.
