Application filed January 11, 1915. Serial No. 1,550.

To all whom it may concern:

Be it known that 1, JOHN E. BEGKMAN, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain'new and useful Improvements in Valves, of which the following is a specification This invention relates to improvements in valves, and while it is shown in the accompanying drawing, and will hereinafter be described as embodied in a motor or engine of the internal combustion .type, yet it is applicable to other kinds of engines, as well as for other purposes, and it consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The main or principal object of the invention is to provide a valve for the intake or exhaust ports of an engine, or the inlet and outlet of any other device to which it inay be applied, which shall be simple and inexpensive in construction, strong, durable,

efficient and reliable in operation, and somade as to permit the gases or fluids which it controls to enter or be discharged from the engine cylinder or other receptacle, with less frictional loss, than has been; possible in methods heretofore in general use.

Another object is to provide means will be permitted to re main in its completely open position, at the desired moment, for a longer period of time than has heretofore been attained.

Other objects and advantages of the invention will be disclosed -in the subjoined description and explanation.

In the accompanying drawing, which serves to illustrate an embodiment of the invcntionFigure 1 is a vertical sectional view through one of the cylinders of an engine and thewalve casings thereof, showing One of the valves in elevation and closed,

while the other valve is shown in vertical section and men Fi ."2 is a ers ective view 'of the valve casing, a fragment of the casing in which it is mounted, and illustrating the means for operating the valve, and Fig. :3 is a detached View of one of the valve operating cams. I

Like numerals of reference refer to corresponding parts throughout the different views of the drawing.

The reference numeral 5 designates the cylinder of the engine, which engine may be of the ordinary, or any preferred construction, but is herein shown as being of the internal combustion type, and as having a crank-casing 6, located beneath the cylinder, which casing may be supported by means of lateral extensions 7, or otherwise, on any suitable support,- (not shown). Located directly opposite each other on the cylinder 5, are valve casings 8, each of which is furnished with a port 9, which communicates with the cylinder and with a port 10, one of which communicates with a supply of motive fluid and the other with the exhaust therefor. In each of the valve casings 8,,of the cylinder, the ports 9 and 10 thereof are by preference aline d, asshown, and the valve casing 5, above said ports is provided with a socket or cavity 11, in

which the upper portion of the valve 12, which is by preference cylindrical in shape, is movably located. The lower portion of the'va-Ive 12, is located in a suitable opening 13, in the lower portion of the casing 8, and is provided with a shoulder 14, from which is downwardly extended a reduced circular portion 15-, which has in its lower end a projection, such as a screw bolt 16, located eccentrically with respect to the part 15'. 0n the lower end of the projection'or bolt 16, is journaled a roller 17, for the purpose to be presently explained. The lower portion of the socket or opening 15, of the valve shoulder 14 a cone ring 18, against which are retained a series of ball bearings 19, which areheld in position by means of an annular ring or cup 20, secured in the lower portion of the socket 13, of the valve casing. txtended through the upper portion of the valve casing 8 and into the socket 11, is a screw bolt 21, which has on its lower end a head 22, provided in its lower surface with a cavity to receive a ball bearing 23, located in a suitable depression 24 in the upper portion of the valve 12, which screw bolt and bearing serve to centralize said valve, as well as to regulate the ease of its move ments, as it is apparent that by tightening the bolt 21, or loosening the same the pressure on the valve can be increased or diminished as desired. The valve 12 is provided with a'port 25, which is extended transversely through the valve and by preference diametrically therethrough, and is adapted to register with the ports 9 and 10 so as to I admit of the passage of gases or fluids to and from the engine cylinder or other receptacle. I

Horizontall journaled in the lower portion of each 0 the valve casings 8, is a shaft 26, which are by preference rectangular in cross section between their journals, and each of said shafts has fitted thereon a block 27, each of which is provided with a cam groove 28, having a lateral oif-set 29 (see Figs. 2 and 3 of the drawing). The shafts 26 may be driven from the crank shaft 30,

- by any suitable means, or otherwise, if preferred, but in the present instance they are shown as being each equipped with'a sprocket wheel 31, around which is extended a sprocket chain 32, which also passes around the sprocket wheel 33, on one end of the crank-shaft. If desired, an adjustable idler 34., mounted on the crank shaft may be employed to take up the slack of the sprocket chain. As the shaft 26, of each of the cam blocks 27 is rotated, it is apparent that the block thereon will turn with its shaft, in which operation the valve 12 will be oscillated by reason of the engagement of the roller 17 with the cam groove 28, so that the port 25 of the valve will be brought into register with the fiorts 9 and 10, and allowed to remain in $110 position for the desired 1 length of time, thus permitting the gases or fluids to pass into the cylinder or other receptacle, or out of the same, with less frictional loss than has heretofore been accomplished. It is obvious that the length of time in which thevalve may be left open, that is, that its port 25 is in register with the j ports 9 and 10, can be regulated by 1ncreasing or diminishing the length of the off-set portion 29'of the cam groove in the cam block. As the roller 19 travels in the cam groove 28, and passes out of the off-set portion thereof, it is obvious that the valve will be turned so as to shut off the gases or fluids to or from the engine cylinder or other receptacle.

It is evident that the invention is subject to some modifications and changes in the details of its construction, and for this reason, I do not desire to be understood as limiting myself to the exact construction shown and described, but may make such changes and alterations as may come within the scope of the appended claims without a departure from the spirit of the invention.

Having thus fully described, my invention what I claim as new and desire to secure by Letters Patent is- 1. A valve consisting of a casing havinga valve seat and provided with a port on each side of said seat, a. valve having a transverse opening adapted to be moved into and out of communication with said ports and mounted in the seat for oscillating movement, an eccentrically disposed projection on one end of the valve, a member having a cam groove engaging said projection and rotatably mounted near one end of the valve, and means to rotate said member.

2. A valve consisting of a casing having a valve seat and provided with a port on each side of said seat and in alinement with one another, a valve having a'transverse opening adapted to be moved into and out of communication with said ports and mounted in the seat for oscillating movement, an eccentrically disposed projection on one end of the valve, a member having a cam groove provided with a lateral off-set engaging said projection and rotatably mounted near one end of the valve, and

' means to rotate said member.

3. A valve consisting of a casing having a valve seat and provided with a port on each iside of said seat, a valve having a transverse opening adapted to be moved into and out of communication with said ports and mounted in the seat for oscillating movement, an eccentrically disposed projection on one end of the valve, a single ball bearing on the other end thereof, a member having a cam groove provided with a lateral ofi-set engaging said projection and rotatably mountednear one end of the valve, and means to rotate said member.

4. A valve consisting ofa casing having a valve seat and provided with a-port on each side of said seat, a valve having a transverse opening adapted to be moved into and out of communication with said ports and mounted in the seat for oscillating movement, an eccentrically disposed projection on one end of the valve, an adjustable single ball bearing on the other end thereof, a member having a cam groove provided with a lateral off-set engaging said 'projec tion and rotatably mounted near one end of the valve, and means to rotate said memher.

5. A valve consisting of a casinghaving a valve seat and provided with a port on gaging one end of the valve, and means to oscillate the valve.
