- the other part 10 of the piston consists of a disk which is secured against the outer edge of the ring portion of the part 9, by bolts 11, which extend through both disk portions.
- the ring portion is made slightly smaller than the two disk portions to make a recess seat for a pack ing ring 12.
- the interior of the ring portion of the piston forms a hollow chamber, in which I place a valve supporting sleeve 13, from each side of the opposite ends of which pins 14 project slidably through and beyond apertures formed in the opposite disks of the piston heads, so as to strike the opposite cylinder heads as the piston reciprocates within the cylinder, for a purpose to be hereinafter explained.
- the sleeve 13 has a central bore in which a plug valve 15 is reciprocally mounted, and the opposite ends of this valve stem are tapered as shown, thus forming a double-ended valve which controls the inlet ports in the ends of the piston.
- inlet ports 16 and 17 are formed with valve seats within the hollow piston head, against one or the other of which the valve 15 is always seated by the pressure of the water, the valve having a movement independent of the reciprocal movement of the sleeve 13.
- the plug valve has a pin 25, which projects from each end of it, through the ports 16 and 17, and this pin is of slightly less length than the pins 14, and is adapted to contact with the cylinder heads 3 and 4, as the piston reciprocates in order to unseat the valve 15, alternately from the ports 16 and 17.
- exhaust ports 18 and 19 which form a communication between the cylinder and the interior of the piston, and these ports are controlled by a double-ended plug valve 20, comprising a stem 21, having a plug valve at each end on the outside of the piston.
- the stem 21 extends through the ports 18 and 19, and is of much less diameter than the said ports.
- The'outside entrances of these ports are formed with valve seats to receive the two tapering plug valves.
- This stem is enough longer than the thickness of the piston head to allow the valves a reciprocative movement to and away from their seats of suificient distance to fully open the ports, and the valves are reciprocally mounted in sleeves 22 and 23, which are connected by pins 24, which extend through them and through the piston head.
- the piston rods are hollow tubes, and the piston 7 extends from the disk 9, through a stuffing box 26, formed in the hub of the cylinder head 3, in which a gland 27 is threaded, the outer end of which is knurled or serrated to be grasped by a suitable pipe wrench or by the fingers of an operator to tighten or loosen it in the packing chamber of the head.

- the piston head is provided with a diaphragm 33, which is cast integral with the disk 9, and extends across and bears against the inside of the disk 10, thus separating the axial inlet and outlet of the piston rods in the piston head from each other, and forming in the piston head two independent compartments 34 and 35.
- the compartment 35 connects the axial aperture inlet of the piston 7, with the cylinders water inlet and valve, and the other compartment 34 receives the exhaust water from the opposite ends of the cylinder through the ports 18 and 19, and the water flows from this chamber through the piston rod 8, and out of its opposite end, which is open, and is arranged to be connected to a water discharge pipe or hose, that leads the waste and out through the piston rod 8.
- the end of the piston rod 8 is also threaded to allow it to be connected to a driving shaft of any machine it is desired to operate by the motor.

- the motors water inlet nipple coupling is connected. to a water supply pipe of the city water supply system of the house, store, shop, or factory in which the motor is to be used, and the water under pressure, which may vary from about twenty to a hundred pounds pressure to the square inch, flows into the water chamber and fills it full, and also flows into the end of the piston 7, through which it flows to the compartment 35 in the piston head, from which it flows through the outlet valves and ports into the opposite ends of the cylinder in alter nate order.
- the double-ended plug valve 15, within the reciprocable valve sleeve 13, is always seated either upon one or the other of its seats, and the valve sleeve is also at the same time against that side of the chamber 35 of the piston, upon which the valve is seated.
- the pins 24 have struck the cylinder head 3, moving the sleeve 22 against the piston and around the exhaust port 18, cutting off the exhaust water through that port.
- the projecting end. of the stem 21 strikes the head 3, and moves the valve far enough to uncover the port 19.
- the live water then flows from piston rod 7, into chamber 35, of the piston, and through the port 16 to the cylinder between the piston, and the cylinder head 3, when its pressure will instantly seat the valve 15, upon the port 17, and one end of the valve 20, upon the port 18, the other end of the valve 20 being off the port 19, and the sleeve 23, in position' to let the exhaust water pass through the said port.

Application filed October 2, 1906. Serial No. 337,077.
To all whom, it may concern.-
Be it known that we, JosEPH P. SHEVLIN and HENRY P. SHEVLIN, citizens of the United States of America, residing at the city and county of Denver and State of Colorado, have invented a new and useful Water-Motor, of which the following is a specification.
Our invention relates to improvements in water motors, and the objects of our invention are: First, to provide an automatic operating water motor. And second, to provide a simple, durable, and economically operating water motor, that is adapted to be attached to the water pressure of city water works, and that is adapted to be used as a motor for various purposes. We attain these objects by the mechanism illustrated in the accompanying drawings, in which:
Figure 1, is a plan view of my improved water motor. Fig. 2, is a vertical, longitudinal, sectional view of the same. Fig. 3, is a transverse, vertical, sectional view on the line 33 of Fig. 2. Fig. 4, is an elevation of the piston, one of the end members of which is removed to show the interior construction. Fig. 5, is a plan view of the piston, and parts connected therewith. And Fig. 6, is a fragmental sectional view, showing the position of the valves and supporting sleeves, when their projecting pins contact with the cylinder heads.
Similar letters of reference refer to similar parts throughout the several views.
Referring to the drawings: The numeral 1, designates the water cylinder, and the nu meral 2 designates the valve cylinder of my improved water motor. The valve cylinder is a tubular cylinder provided with suitable cylinder heads 3 and 4, from which feet 5, depend, that are adapted to be secured to a floor or bench or other suitable supporting foundation. These cylinder heads are provided with hubs, and are secured to the cylinder by bolts 5A, which extend from one cylinder head to the other along the outside of the cylinder. The valve cylinder is provided with a piston head 6, which has piston rods 7 and 8 projecting from the opposite sides of it, which project through hubs of the cylinder heads. Both of these piston rods are hollow and the piston head is also hollow, and is constructed as follows: The piston is made in two parts 9 and 10, and the part 9 consists ,of a disk portion having an integral ring of slightly smaller diameter th an the disk portion which projects from the opposite side from its piston rod 7; the other part 10 of the piston consists of a disk which is secured against the outer edge of the ring portion of the part 9, by bolts 11, which extend through both disk portions. The ring portion is made slightly smaller than the two disk portions to make a recess seat for a pack ing ring 12. The interior of the ring portion of the piston forms a hollow chamber, in which I place a valve supporting sleeve 13, from each side of the opposite ends of which pins 14 project slidably through and beyond apertures formed in the opposite disks of the piston heads, so as to strike the opposite cylinder heads as the piston reciprocates within the cylinder, for a purpose to be hereinafter explained. The sleeve 13, has a central bore in which a plug valve 15 is reciprocally mounted, and the opposite ends of this valve stem are tapered as shown, thus forming a double-ended valve which controls the inlet ports in the ends of the piston. These inlet ports 16 and 17 are formed with valve seats within the hollow piston head, against one or the other of which the valve 15 is always seated by the pressure of the water, the valve having a movement independent of the reciprocal movement of the sleeve 13. The plug valve has a pin 25, which projects from each end of it, through the ports 16 and 17, and this pin is of slightly less length than the pins 14, and is adapted to contact with the cylinder heads 3 and 4, as the piston reciprocates in order to unseat the valve 15, alternately from the ports 16 and 17.
At diametrically opposite points on the piston disks from the inlet ports 16 and 17, are exhaust ports 18 and 19, which form a communication between the cylinder and the interior of the piston, and these ports are controlled by a double-ended plug valve 20, comprising a stem 21, having a plug valve at each end on the outside of the piston. The stem 21, extends through the ports 18 and 19, and is of much less diameter than the said ports. The'outside entrances of these ports are formed with valve seats to receive the two tapering plug valves. This stem is enough longer than the thickness of the piston head to allow the valves a reciprocative movement to and away from their seats of suificient distance to fully open the ports, and the valves are reciprocally mounted in sleeves 22 and 23, which are connected by pins 24, which extend through them and through the piston head. These pins have a IIO sliding movement through the piston, and as the piston approaches either end of the cylinder, they will contact with the cylinder head, causing the sleeve adjacent to said head to move back against the piston, and around the adjacent exhaust port, while the sleeve at the opposite ends of the pins is moved away from the end of the piston, and the adjacent exhaust port, the valve 20 be ing thrown just after the sleeve is shifted, as will be more fully described hereinafter.
The piston rods are hollow tubes, and the piston 7 extends from the disk 9, through a stuffing box 26, formed in the hub of the cylinder head 3, in which a gland 27 is threaded, the outer end of which is knurled or serrated to be grasped by a suitable pipe wrench or by the fingers of an operator to tighten or loosen it in the packing chamber of the head. The piston extends through this gland into the water inlet chamber 1, which 'is formed of a piece of tubing that is threaded to the outside of the hub of the cylinder head 3. The opposite end of this tube is closed by a plug 28. A water inlet nipple 29 is connected to the water inlet chamber, and its outer end is provided with a part of a hose or pipe coupling or union 30, which enables it to be connected to a hose or pipe, which leads to a city or other water supply pipe. This water inlet chamber is made long enough to receive the piston rod 7, when the piston head is at the end of its stroke against the cylinder head 3, and the piston rod 7 is of such a length that its end will project just through the gland in the water chamber when the piston head is at the opposite end of its stroke against the opposite cylinder head 4. The other piston rod 8 extends from the disk 10 of the piston head through the cylinder head 4, and a packing chamber 31 is formed in its hub, to which a gland 32 is threaded, the outer end of which is serrated or knurled to be turned by the fingers of an operator or by a suitable wrench, and this piston is made long enough to still extend beyond this gland when the piston head is at the opposite end of its stroke from the cylinder head 4. The piston head is provided with a diaphragm 33, which is cast integral with the disk 9, and extends across and bears against the inside of the disk 10, thus separating the axial inlet and outlet of the piston rods in the piston head from each other, and forming in the piston head two independent compartments 34 and 35. The compartment 35 connects the axial aperture inlet of the piston 7, with the cylinders water inlet and valve, and the other compartment 34 receives the exhaust water from the opposite ends of the cylinder through the ports 18 and 19, and the water flows from this chamber through the piston rod 8, and out of its opposite end, which is open, and is arranged to be connected to a water discharge pipe or hose, that leads the waste and out through the piston rod 8.
water away from the motor. The end of the piston rod 8, is also threaded to allow it to be connected to a driving shaft of any machine it is desired to operate by the motor.
The operation of our improved water motor is as follows: The motors water inlet nipple coupling is connected. to a water supply pipe of the city water supply system of the house, store, shop, or factory in which the motor is to be used, and the water under pressure, which may vary from about twenty to a hundred pounds pressure to the square inch, flows into the water chamber and fills it full, and also flows into the end of the piston 7, through which it flows to the compartment 35 in the piston head, from which it flows through the outlet valves and ports into the opposite ends of the cylinder in alter nate order. The double-ended plug valve 15, within the reciprocable valve sleeve 13, is always seated either upon one or the other of its seats, and the valve sleeve is also at the same time against that side of the chamber 35 of the piston, upon which the valve is seated. Now assuming that the piston has just reached the limit of its stroke at the inlet end of the cylinder, the pins 24 have struck the cylinder head 3, moving the sleeve 22 against the piston and around the exhaust port 18, cutting off the exhaust water through that port. Immediately thereafter, the projecting end. of the stem 21, strikes the head 3, and moves the valve far enough to uncover the port 19. Simultaneously with the contact of the pins 24, with the cylinder head 3, the pins 14 of the sleeve 13, contact with the head 3, and move the said sleeve against the disk 10, of the piston, cutting off the live water from inlet port 17, and at the same instant that the pin 21 of the double valve 20, contacts with the head 3, the pin 25 of valve 15, contacts with the head, and moves the valve away from the port 16. The live water then flows from piston rod 7, into chamber 35, of the piston, and through the port 16 to the cylinder between the piston, and the cylinder head 3, when its pressure will instantly seat the valve 15, upon the port 17, and one end of the valve 20, upon the port 18, the other end of the valve 20 being off the port 19, and the sleeve 23, in position' to let the exhaust water pass through the said port. Thus, as the live water enters rear of the piston, the piston will be moved forward, and the exhaust water forward of the piston, will pass through the port 19, into the chamber 34, When the piston reaches the opposite end of the cylinder, the pins 14, 21, 24, and 25, will contact with the cylinder head 4, reversing the valves and sleeves, so as to admit the live water through port 17 forward of the piston, and permit the exhaust water to pass through port 18, and out through the piston other manufacturing establishments.
