ROTARY ENGINE-VALVE.

To all whom it may concern:

Be it known that I, Vrc'ron H. ANDERSON, a citizen of'the United States,.residing at Mount Vernon, in the county of Kennebec 5 and State of Maine, have invented new and useful Improvements in Rotary 'Engine- Valves, of which the following is a specification.

This invention relates to rotary valves for internal combustion engines of the multiple cylinder type, the object in view bein to roduce a valve of the'class specified w ich is adapted to take care of the lntake and exhaust of a multiple cylinder engine each cylinder of which only requires a single port to take care of both the intake and exhaust of the fresh mixture and burned gasesL.

One of the chief object's of the present invention is to produce a valve of the character stated in which there are self-contained intake and exhaust manifolds, whereby the inflowing cool mixture will be heated by the burned gases upon their movement through the valve to the exhaust chamber.

A further object of the invention is to produce a valveof the class above defined, the construction of whic renders it reliable and efficient, enables the same to be lubricated without permitting the lubricant to enter the engine, which effectively excludes foreign. matter, and which may be driven with a very small percentage of power of WitE the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawings: Figure l is a cross section through a multiple cylinder engine embodying the present invention. Fig. 2 is a horiz ntal section on the line' 22'of Fig. 1. 3 is a plan view of the inner portion of'the valve including the valve shaft, the manifold forming partition, and other parts intimately associated with the valve shaft. Figs. 4:, 5 and 6 are,

respectively, sections on the lines H, 55 and 6-6 of Fig-:2, omitting all parts except the valve itself. Fig; 7 is a section on the I 8 is a detail view 3 one of the rings.

Specification of.Letters fatent.

. shown, the cylinders A and B, four in number, are arranged at an acute angle to each other but it will of course be understood that the angle between the cylinders Aand B maiy be varied to suit the will of the manu acturer and that, if desired,- the said cylinders A and B may be arranged ver tlcally or in parallel relation to each other.

The main feature of the invention resides.

in the valve which is designated enerally at D, the same comprising a centre? and an outer cylindrical tubular shell 2, the medial portion 3 and'the extreme end porshaft'l,

tions 4 of which are shown as imperforate.

The portions5'and f5 lying at opposite sides of the medial portion 3 are provided each -with an inlet port and an exhaust port, the

portion 5 at one side comprising the inlet ported portion at the opposite side of the imperforate medial portion 3 is formed with an inlet port 9 and an exhaust port 10. In

-cycle engine and therefore revolves at one half the speed of the engine shaft, the intake .and exhaust ports at one side of the central portion 3 are arranged substantially at ninety degrees apart so that the exhaust.

stroke will be followed by the intake stroke,

lport 7and the exhaust port 8, while the-' the remainder of the shell in line with said ports being imperforate for approximately one hundred and eighty degrees so as tof'provide for the compression and firing strokes.

Furthermore, the ports 9 and "10, collectively, are arranged ninety degrees from the ports? and 8 so that the explosions in the four cylinders will follow each other successively. designates a manifold forming Pattisimilar semi-circular end wall 13 which closes one half of that end of the cylinder. Between its ends, the partition or Web 11 is given a quarter twist at 14, said twisted portion of the partition or web lying Within the imperforate medial portion 3 the shell 2 This quarter twist of the web or partition 11 is required in order to receive and deliver the fresh mixture'to thecylinders and also to receive and discharge the burned gases therefrom. The shell 2 is supported by means of the end walls 12 and 13 and the outer edges of'the partition or web 11 including the angular or twisted portions 14; thereof.

The shaft 1 is .journaled in bearing memhers l5 and 16 and is provided at one end with a squared or non-circular portion 17 on which is mounted a silent chain wheel 18 from which a silent driving'chain extends to the crank shaft of the engine. On the same squared portion 17 of the shaft is mounted a fan belt pulley 19 held in place' by a nut 20. The wheel 18 is formed with anextended hub 21 forming another-jean nal which is mounted in a bearing member 22, the bearing members 15, 16 and 22 forming parts of the engine frame. At the opposite end the shaft 1 has fast thereon a silent chain wheel 23 from whiclra chain extends to the magneto shaft. .Keys 2 1 are employed'to securely lock the wheels 18 and 23 to the shaft 1. The shaft 1 is further provided with flanges or collars 25 and 26 beyond the ends of the valve, said collars working against the adjacent end walls of the valve chamber so as to prevent leakage of mixture or burned gases from the valve chamber at said points and also to prevent the oil from the journals 15 and 16 from entering the intake chamber 27 and the exhaust chamber 28 to which are connected suitable intake and exhaust pipes as may be found convenient.

Oil is introduced through an opening 29 into a groove 30 in the inside of the valve chamber wall where it enters an annular series of oil grooves 31 inthe outer face of the .imperforate medial portion 3 of the shell, the oil being conducted through the grooves 31 to other grooves 32 and 33 in a pair of skeleton shaped packing rings surrounding the ported portions 5 and 6 of the valve shell so as to produce a snug fit between the valve and its containing casing, preventing the lubricating oil from reach ing the intake and exhaust ports and also preventing leakage of the mixture and er;- haust gases at such points. y

In operation, it will be understood the valve as a Whole herciuabove described may be operated or revolved at one half the veryv small percentage of the engine power. The timing of the intake and exhaust is fixed and therefore invariable so that the very best results may be obtained as regards the power and general efficiency of the ensmooth in its operation. The inlet and exhaust manifolds are selfcontained withinv the shell'of the valve and thus the incoming mixture is heated. by the exhaust, producing at all times a good explosive mixture, resulting in better combustion, increased power and reduction in the accumulation of carbon in'the engine cylinders and on the heads of the pistons. It will be observed that there is only one port in each cylinder, which port takes care of both the inlet of the charges and the exhaust of the,

burned gases. Under the arrangement of the valve in its relation to the engine cylinders hereinabove described, the valve itself is protected from the highest temperatures which occur withinthe cylinders at the time the explosions take place. Having thus described my invention, 3: claim 1. In a multiple cylinder ll-type internal combustion engine, the combination of gularlv related cylinders, a valve chamber located between the angularly related cylinders and formed with acylindrical bore and a single port for each cylinder acting both as an intake and exhaust port, a rotary cylindrical valve mounted to revolve in said chamber and embodying a tubular shell having an imperforate medial portion and ported portions at opposite sides of said medial portion, each formed with an inlet port and an exhaust port which successively register with the ports of the said cylinders, an intake chamber at one end of said valve, an'exhaust chamber at the other end of said valve, and an internal partition ex tending longitudinally" and diametrically of said shelland shaft and forming valve-contained intake and exhaust manifolds.

2. In a multiple cylinder ll-type internal combustion engine, the combination of angular-1y related cylinders, a valve chamber located between said angular-1y related cylinders and formed with a cylindrical bore and a single port for each cylinder acting both as an intake and exhaust port, a rotary cylindrical valve mounted to revolve speed of the engine shaft, requiring but a. v

. gine. Furthermore, the valve is silent and in said chamber and embodying a tubular shell having an imperforate medial portion and ported portions at opposite sides of said medial portion, each formed with an inlet port and an exhaust port which successively register with the ports of the respective cylinder, and an internal partition extending longitudinally and diametrically of said shell and foi-ming Valve-contained intake I and exhaust manifolds.

In testimony whereof I aflix my signature in presence of two witnesses.
