WILLIAM E. PEARSON, OF BOSTON, MASSACHUSETTS.
ROTARY MOTOR.
Specification of Letters Patent.
Patented Oct. 29, 1912.
Application filed February 7, 1910. Serial No. 542,580.
To all whom it may concern:
Be it-known that I, WILLIAM E.'PEAR soN, a citizen of the United States, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Rotary Motors, of
which the following, taken in connection with the accompanying drawings, is a specification.
My invention relates to that class of liquid motors in which the pistons are attached to a rotating piston-carrier and consists in a changeable by-pass device, by the aid of which the motor may be run equally well in either direction.
The mechanism is illustrated in the accompanying drawings in which;
Figure 1 is a side elevation of the motor; Fig. 2 is a plan of the same; Fig. 3 is a vertical section taken on line 33 of Fig. 2; Fig. 4: is an elevation, on an enlarged scale, of the by-pass valve; Fig. 5 is a crosssection taken on line 55 of Fig. 4.
In the drawings A, B represents the case that incloses the working parts of the motor. The ports C and D are, or may become respectively inlet or outlet ports to agree with the direction which the motor is being forced to run.
The piston-carrier E, Fig. 3, is mounted upon the shaft S, Fig. 2, through which the energy of the motor is transmitted to the apparatus to be driven. The pistoncarrier has connected to it radially sliding pistons, P, P, P P P, P", P and P arranged as shown in Fig. 3. These pistons are controlled by the disk F mounted upon the shaft F. The shaft F is adjustable so as to allow for the wear of the pistons and is held in place by the nut F Delivery ports C and D serve to conduct to or lead away from the pistons during the action of the motor.
R and R are by-passes connecting the port ways C and D to the hollow valve K. The said hollow valve K is shown on an enlarged scale in Figs. 4 and 5. This valve is constructed and mounted upon its shaft in such a manner that it may be turned by the lever L, Fig. 2, acting through the shaft L so that its ports K and K, may be made to register with the release port K and by-passes R and R, as will be explained. The lever L is provided with a latch N which en ages with notches, like N, made in the bracfiet piece M, see Fig. 2. I
The operation of my motor may be explained as follows: Suppose the motor to be run in the dire"tion from right to left, that is the driving liquid enters through the ports D, D, that is, impinges on the piston P and coacts on the piston l? but is about to cease tohave any action on said piston P as that piston is passing the release port K and the chamber between the pistons P and P becomes an open one, as the piston P opens in to the delivery port C and thence to the'outlet port (l. While this action is going on the ports K and K in the hollow valve K admit of a free passage 01 the discharge liquid into the outlet port 0.
In case we wish to run the motor from left to right then the liquid comes in through ports C and C. The hollow valve K is turned so as to cause K to register with the release port K and the port K will register with the by-pass R, and the motor will be free to run in the desired direction.
A careful inspection of the arrangement of the pistons, ports and by-passes and hmlow valve K as above explained will show that under no circumstances will there be any clogging action in the chambers between the pistons, regardless of the direction that the motor is run.
In this class of rotary motors, i. e. IGVGISZ- ble, the pistons act as power generators only while passing from the delivery port to a point situated half way between the said delivery port and the full discharge port, in my motor I have placed a release port at the said halfway point so that there can be no check to the free advance of the pistons after they have ceased to act as power generators and are simply passing to the full discharge port and thence back to the starting point. i
I claim A rotary liquid motor, comprising a casing having inlet and exhaust ports, a rotary piston, a release port located between the inlet and exhaust ports and communicating mi i caasaa with the piston chamber, by-passes in comname to this specification in the presence of munication With said inlet and exhaust two subscribing Witnesses, on this 5th day of ports, and a hollow cylindrical valve having February A. D. 1910.
ports, whereby said release port can be I WILLIAM E. PEARSON. 5 place in communication with either of said. Viitnesses:
