W wll jzgzesses. fie 4 CHESTER? N. STEVER, OF MECHANICS VALLEY, PENNSYLVANIA.
GAS-ENGINE.
To all whom, it may concern:
Be it known that 'I, CHESTER N. STEVER, a citizen of the United States, residing at Mechanics Valley, in the county of Bucks and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Engines, of which the following. is a specification.
This invention relates to gas engines and more particularly to internal combustion engines, and has for its object the provision of an internal combustion engine provided with a novel valve mechanism comprising a single rotary port controlling the inlet and exhau'st of the fresh and burnt gases, respectively, a plurality, of ports being formed through the concentric sections of the valve whereby connection is established between the engine cylinders and the inlet and exhaust pipes at proper predetermined intervals, the ports being arranged oppositely to each other. whereby the pressure is at all times balancedto have. a smooth and noiseless running of the engine and secure the maximum degree of power.
An important part of this invention is the provision of a valve for internal combustion which is so arranged as to eliminate the side pressure which is one of the objections to the rotary valves now in use.
More specifically, the object of the inyention resides-in the provision of an internal combustion engine provided with. a
rotary valve comprising a central inlet passage chamber and an outlet exhaust chamber, both chambers being provided with ports disposed axially of each other and registering at predetermined intervals with ports formed in the engine cylinders; the valve being rotatably mounted in a valve casing, and the entire valve mechanism being driven by a crank shaft of the engine.
Other objects such as simplicity in construction, comparative cheapness of manufacture, and efiiciency and durability in service will be brought out in the following description and illustrated in the accompanying drawings, in which Figure 1 isa side elevation of an engine embodying my invention with part of the side wall broken away to show thelocation of the valve and position of the pistons in the cylinders, and a part of the valve casing broken away to show the connection of a valve port with a cylinder port, Figs. 2, 3, 4 and 5 are cross-sectional views show- Specification 'of letters Patent.
ing the position of the valve at each stroke of the engine; Fig. 2 showing the valve at exhaust, Fig. 3 at intake, Fig. 4 at compression', and Fig. 5 the position of the valve Patented June 29, 1915. Application filed June 24, 1914. Serial No. 847,087.
on the working stroke, and Fig. 6 is a horizontal longitudinal sectional view on' the line 6-6 of Fig. 1, showing the valve casing and the tubular members of the valve partly broken away.
In the drawings like figures designate the same parts in the several views.
The engine casing is indicated by the letter A; 1 indicates my improved Valve, and 2, 3, 4 and 5 the cylinders; 6 the crank of the engine which is connected to the piston rods .7 of the pistons 8. The bearlngs 9 of the shaft are carried by the ends of the casing and are made removable to permit of removing the shaft. Each-of'the cylinders 2, 3, 4 and 5 is provided at its upper end with ports 10 which register with ports 11 in the "alve l and communicats with the casing 12 which incloses the valve 1 and'extends lengthwise of the engme and across the top of the cylinders. Thls casing 12 is common to all the cylinders and forms a casing for the valve mechanlsm. The valve comprises two tubular members 13 and 14 which are rotatably mounted and disposed longitudinally in the casing 12. The tubular member 14 is spaced apart from the tubular member 13 and sleeved therein. 13 is closed as at 15 and the other end 16 is connected to the. intake pipe by any suit- One end of this memberable means. The member 14 is closed at one end and its open end 17 connected with the exhaust pipe. The diameter of each of these members 13 and 14 is the same throughout its entire length.
. The valve lis rotatably mounted inbearlugs 18 and is rotated by means of the crank shaft on which is mounted a beveled gear 19 adjoinin the fly wheel 20 and is in mesh.
with a beve ed gear 21 on the driven shaft 22 which extends through a lower collar bearing 23 and through an upper collar bearing 24, and on the up or end of the shaft 22 is secured a bevele gear 25 which is within the casing ca 27 and which meshes with the larger bevele gear 26 which is rigidly mounted on the member 13. The ear cap 27 is flanged at 28 and connecte by. he ts 29 to the adjacent end of the casing of the en 'ne. To provide against unseating the va ve in case an explos1on should occur in the exhaust chamber of the valve 1 I provide a buffer 30 which is placed between the flange 28 on the cap 27 and the engine casing engine started' and the valve moved from the position shown in Fig. 2 to the position shown in Fig. 3, the down stroke of the piston draws the fresh gas into the cylinder when the valve intake ports are in the position shown inFig. 3 and as the intake is cut 03 by the rotation of the valve the gas becomes compressed by the upward stroke of the piston as shown in Fig. 4, and as the valve continues to revolve the explosion or working stroke follows as shown in Fig. 5, and when the exhaust ports again come into operative relation with the, cylinder ports as shown in Fig. 2 the burnt gas passes out of the cylinder through the ports and into and out of the exhaust chamber, and when the revolving of the valve has again brought the intake ports in alinement with the cylinder ports the cylinder becomes again charged and the operation of com pression, explosion and exhaust are continued indefinitely.
By the foregoing description of the construction and operation of my invention it will be apparent that I have produced a valve in which the pressure is equally distributed and maintained at all stages of the operation of intake, compression, explosion, working stroke'and exhaust, thereby-overcoming the objectionable side pressure of the constructions heretofore, and assuring a continuous evenly balanced and smooth movement of the engine.
Having thus described my invention what I claim is:
1. In combination with the cylinders of an internal combustion engine, a valve casing, a cylindrical valve mounted within said casing, said valve comprising an exhaust chamber running its entire length and having an opening in one end for connection with the exhaust pipe, said chamber being the same diameter throughout, an inner chamber spaced within said exhaust chamber, said inner chamber having an opening in its end opposite to the open end of the exhaust chamber for connection with the gas supply, said chamber being of the same diameter throughout, ports for communication between said cylinders and said valve chambers, the ports from the inner chamher having straight walls, means for balancin said valve, and means for rotating said va ve.
' 2. In combination with the cylinders of an internal combustion engine, a valve casing, a cylindrical valve mounted within said casing, said valve comprising an exhaust chamber running its entire length and hav-- ing an opening in one end for connection with the exhaust pipe, said chamber being the same diameter throughout, an inner chamber spaced within said exhaust chamber, said inner chamber having an opening in its end opposite to the open end of the exhaust chamber for connection with the gas supply, said chamber being of the samediameter throughout, ports for communication between said cylinders and said valve chambers, the ports from the inner chamber having straight walls, said chambers being axially'disposed as to one another for caus ing an evenly balanced valve, and gear mechanism connected to the main drive shaft of said engine for rotating said valve. In testimony whereof I hereto aflix my signature in the presence of two witnesses.
