To all whom it may concern.'

Be it known that I, MARTIN M. HANsoN, a citizen ofthe United States, residing at Clearwater, in the county of Antelope, State of Nebraska, have invented a new and useful Revoluble Valve for Internal-Combustion Motors; and I do hereby declare the followingto be a full, clear, and exact description Vof the invention, such as will ensprings, valve seats, valve stems, adjustingnuts, and all other noise: attachments and troublesome devices. v

A further object of the invention is to provide a revoluble motor valve, which is an improvement over the so-ealled motor sleeve valve, thereby dispensing with the eccentric shaft, the inner and outer sleeves, connecting rods andjunk rings, and thereby providing a motor revoluble valve, which is durable, positive, and' which is constructed of few parts, thereby enablin a, motor revoluble valve of this kindto e constructed or manufactured for a small cost and sold at a reasonable profit.

A further object of the invention is to provide a multiple cylinder motor havin a revoluble cylindrical tubular valve provi ed with a multiple of intake and exhaust ports for controlling the intake of the charges and the exhaust of the utilized gases into and from the cylinders, said valve being given a positive drive by means of a noiseless chain or gear mechanism from the crank slaft, said mechanism being timed four to one. For instance said valve is designed to be given one eighth turn to each upward and downward stroke of the piston. or one fourth turn to each turn of the crank shaft.

A further object involved by the provision of the improved motor revoluble valve is the elimination of wear on the several parts of the valve mechanism, in fact, owing to the construction of the valve the wear is reduced to a minimum.

A further object of the invention is to provide a valve of this kind which is positively impervious to air or gas, thereby 'insuring flexibility of thel operatingl parts, *longA service, increasing power, and lowering the costl of construction, as well as insuring quietness, as well as simpliclty, lessenmg the cost of operatlon, and also reduclng carbon troubles.

In practical fields the details of construction may necessitate alterations falling with- 1n the scope of what is claimed.

The invention comprises further Afeatures and combination of parts as hereinafter set forth shown in the drawings and claimed.

In the drawings Figure 1 is a View in elevation of the upper portions of the cylinders of a multiple cylinder internal combustion motor, showing the revoluble valve as applied thereto.

Fig. 2. is a longitudinal sectional view through the valve structure, showing the multiple cylinder motor in elevation 'in the rear.

Fig. 3 is a sectional view on line 3 3 of Fig. 2, showing the exhaust port of the cylinder closed, and a transverse intake passage of the valve in registration with the intake port of the cylinder.

Fig. 4 is a view similar to Fig. 3, also showing the exhaust port closed and the intake passage/of the valve out of registration with the intake port of the cylinder, consequently the piston (not shown) of the cylinder is on its compression stroke.

Fig. 5 is a sectional view similar to Figs. 3 and 4, the exhaust ports still closed, as well as the intake port, since the intake and exhaust passages of the valve areI still out of registration therewith, consequently the piston (not shown) of the cylinder is on its explosion or working stroke.

Fig. 6 is a sectional view similar to Figs. 3, 4 and 5, showing the exhaust port open and the intake port still closed. in which case the piston (not shown) of the cylinder is on its exhaust stroke, thus it will seen by reference to the previous figures that the valve has made one half a revolution to two complete revolutions of the crank shaft (not shown) of the engine.

Figs. 7 8, 9, and 10 are views similar to Figs. 3, 4, 5 and 6 showing the saine relative ositions of the valve as previously discloseld in Figs. 3 to 6 inclusive, but conveying the' fact that said valve has moved its other half revolution to two more complete revolutions of the crank shaft (not'shown), in which case it will be observed that the crank shaft makes four `Complete revolutions to one revolution of said valve. Fig. 11 is a longitudinal section of a part of the valve. 1

Referring more especially tothe drawings, a, b, c and d designate the' multiple of cylinders of the motor, and as shown in Figs. 1 to 10 inclusive said cylinders are constructed with double -walls 1 and 2, spaced, whereby a water jacket 3 is constructed. The cylinders are arranged in parallel, and in consecutive order as designated. The corresponding portions of the outer walls of said cylinders are provided with semi-cylindrical bearings 4, and the inner portions of these bearings have hollow'or tubular connections 5 with the inner wall of said cylinder, and by means of the hollows or passages of said connections 5 exhaust and intake ports 6 and 7 are provided for the cylinders. A revoluble cylindrical valve 8r is mounted in the bearing 4 and is constructed tubular, and diametrically opposite ortions thereof are provided with a multiple of intake and exhaust openings 9 and 10, and transverse tubes 11 rectangular in cross section connectv the diametrically opposite portion of the valve adjacent the openings, said tubes having intake and exhaust passages 12 and 13, which are designed to register with the intake and exhaust ports 6 and 7 .l In order to hold the valve in its bearing 4 a semicylindrical cover plate 14 arches over the valve cylinder, and is provided with flanges 15. Suitable screw bolts 16 are threaded through the flanges 15 and into the outer wall 2 of the cylinders of the motor, thereby securing the cover plate in place. The coverI plate is provided with a plurality of intake and exhaust ports 17 and 18, which are designed to be registered with by the intake and exhaust passages 12 and 13. The c lindrical valve 8 between the intake an exhaust openings 9 and 10 is provided with annular grooves or recesses 19, arranged in pairs and having suitable packing rings 20 therein, to insure against leakage ofthe charges. One end of the cylindrical valve has an integral collar 21 and which end is v closed as shown at 22. This collar 21 engages the corresponding ends of the bearing 4 and the cover plate 14, thereby preventing axial movement of the valve in one direction. The end 22 is closed, owing to the provision of an axial lextension 23, which is provided with a suitable sprocket 24, which, by means of a noiseless chain 25 may be geared to the crank shaft (not shown) of the motor, said earing to be so constructed, that the cylin ical valve will make one complete revolution to every four complete revolutions of the crank shaft. If desired gears may be substituted for the noiseless chain drive. The other end 26v of the valve is extended, and has secured thereon by means of the screws or the like 27 a collar or ring 28, which engages the corresponding end of the bearing 4 and the cover plate 14, 70 in order to prevent axial movement of the valve` in the opposite direction.

Referring tothe cylinder a,"the operation will be understood as follows; particularly y when tracing the positions of thev valve as shown in Figs. 3 to 10 inclusive. When the valve is in the position shown in Fig. -3 the piston of cylinder a is on its intake stroke, the passage `12 is in registration with the openings or ports 7 and 17, while the'pas- 80 sage 13 is out of registration with the ports or openings 6 and 18. As the crank (not shown) moves the piston on its down stroke the valve 8 is moved to the position shown in Fi 43 then the crank will start moving 85 the plston (not shown) on its compression stroke, and while the valve is in the position' shown in Fig. 5, the' piston (not shown) is on its explosion or Working stroke. The piston (not shown) then moves upwardly, 9o consequently making two complete revolutions of the crank shaft (not shown), bringing the valve to the osition shown in'Fig.

6, hence exhausting t e utilized gases, said valve having made one half revolution. By referring to Figs. 7 to 10 inclusive, it will be seen that the same cycles of the valve and the piston arc repeated, the valve making another half revolution to two complete revolutions of the crank shaft (not shown), consequently completing a full revolution of the.valve to four revolutions of the crank shaft. The same operation of the, valve with relation to the cylinders b, c and d are performed. However, it is to be understood that should the valve and its passages l2 and 13 be constructed, in order to permit the intake and exhaust of the charges of the several cylinders to alternate in such wise that only one cylinder at a time will be exploded, said structure will fall within the right of the inventor. y

The invention having been set forth what is claimed as new and useful is y 1. In an internal combustion motor, a 'cas- 115 ing having a multiple of combustion chambers, the end and cylindrical walls of each chamber comprising inner and outer thicknesses and a water space between said thicknesses, the outer thicknesses of said walls of the chambers having an elongated bearing semi-cylindrical in cross section extending transversely of the casing and off-set to one side of the chambers, the inner part of said semi-cylindrical bearing having at intervals integral connections with the respective inner thicknesses of thewalls of said multiple of chambers, a semi-cylindrical cover plate arching said bearing and being secured to the outer thicknesses of said multiple chalnber Walls, thereby forming an elongated transversely disposed cylindrical bearing, said semi-cylindrical bearing having intake and exhaust ports with said chambers formed through said integral connection With the inner Wal-ls of said chambers, said cover plate having intake and exhaust ports diametrically opposed to the rst'intake and exhaust ports` and adapted for communication to the intake and exhaust manifolds, a-

cylindrical tubular valve closed at one end and open at the other mounted in said cylindrical bearing, said valve bein ,provided with transversely disposed inta e and exhaust, passages at angles to each other and having their-opposite ends adapted to register with the diametrically opposed intake and outer thicknesses, a valve bearing. comi prising a semi-cylindrical wall connecting i the outer thicknesses of the Walls ofsaid chambers at correspondn points, said semi- Cylindrical wall of the, va ve bearing at corresponding points integrall connectin the inner thicknesses of the wa ls of said c ambers, said integral connections with the inner thicknesses having intake and exhaust ports therethrough and in communication With said chambers, a cover plate4 arching a valve in saidbearing to retain the valve in place, said cover plate having intake and exhaust ports diametrically opposed to the intake and 'exhaust ports of said integral connections, a cylindrical valve in said bearing and provided with intake and exhaust ports at angles to each other and having their opposite ends adapted to register with the diametrically opposed intake and exhaust ports of the bearing and the cover plate on every half revolution of the valve, said valve being tubular and provided with a flanged closed portion at one end to engage one end of the bearing, and a removable rin removably secured to the other end o the valve to coperate with the other end of the bearing, whereby axial movement of the` valve may be avoided, said other end of the valve being open, whereby exterior `air may enter the valve to assist in cooling the same.

In testimony whereof I. have signed my name to this specification in the presence of. tvvo subscribing witnesses.
