HOWARD, BEIDLER GOODHART, 0F MACUNGIE, PENNSYLVANIA, ASSIGNOR OF ONE- TI-IIRD TO GEORGE J. BOGERT, OF EMAUS, PENNSYLVANIA, AND ONE-THIRD T0 ROY R. READINGER AND ONE-THIRD TO HORACE F. NEUMEYER, BOTH OF MA- CUNGIE, PENNSYLVANIA.

To all whom it may concern I Be it known that I, HOWARD B. Goon.

' and State of Pennsylvania, have invented a new and useful VVater-Motor, of which the following is a specification.

The present invention relates to improvements in water motors, the primary object of the invention being the provision of a simple form of motor in which the piston is disposed in an annular chamber and is so combined witha valve to actuate the same that a continuous flow of water entering the casing will impart an oscillatory movement to the piston and shaft.

A further object of the present invention is the provision of a water motor, the main casing of which is composed of two identically shaped members forming an annular motor or piston chamber provided with superposed inlet and outlet conduits whereby a continuous stream of water is conducted to the chamber and thereaway from so as to act upon a piston disposed for oscillation within the chamber to impart an oscillatory movement to said piston and its shaft, a-peculiar form of valve mechanism being provided and controlled by the piston during its oscillation or more properly speaking at the end of the stroke of each oscillation to conduct the water in the proper direction to impart the desired oscillatory movement to the piston and shaft, this specialform of motor being especially desirable for use in connection with washing machines, vacuum cleaners and in any form of mechanism where a re'ciprocatory With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts'and in the details of construction hereinafter described and claimed, it 'being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

of the 'plungers of the same being shown in section. Fig. 3 is a plan view of the interior of the upper member of the casing showing the position of the valve normally actuated by its spring, the arrow indicating the direction of travel of the piston while the'valve is in such position. Fig. 4 is a section taken on line 44 of Fig. 2 through the entire casing. Fig. 5 is a detail longitudinal sectional view of the-valve per 86. Fig. 6 is a section taken on line 6-6 of Fig. 3.

Referring to the 'draw-ings,the, numeral 1 designates the motor casing which is composed of the lower member 2 and the upper member 3, both of which are provided with' The lower member 2 is provided with the concentric boss 4:, having the concentrically disposed socket'5 for the reception of the lower end of the piston or rotor shaft 6, the said member 2 being further provided with the concentric socket or receptacle7 which with the oppositely disposed receptacle 10 of the member 3 provides a compartment for the disk 11 provided with the sleeve 12 which is keyed to the shaft 6, and thereby provides an end thrust device or holder for the shaft 6, and at the same time provides a medium for carrying the rotor or piston as will later appear. I A segmental projection 141 is provided upon the member 2 and carries a packing strip 15 to rovide water tight connectior. at such point with the upper member 3.

The disk 11 has formed integral therewith, the segmental projection 16 whose shoulders 17 and 17 are'disposedat the .ends of the respective oscillations or strokes of the piston, to abut .the corresponding shoulders 14 and 14" of the projection 14,

This projection 16 in line with the center. line between the" stud 24, to which is properly connected thedoubledleafspring 25 which is wound to form a single helix with its terminal 26 disposed away from its side of the piston, the purpose of which will presently appear.

The upper section or member 3 of the motorhas a lug 27 formedintegral therewith, the shoulders 27' and 27" of which are adapted to be above andin line with the shoulders 14 and 1 4" of the segmental projection 14 of the member 2 and thus provide a proper space as at 60 for the passage of the lug 16' during the oscillation of the piston or rotor. Formed integral with the projection 27 is a casing 28, which constitutes the valve support. The casing 28 is rigidly supported transversely of a portion of the channel 9 and has the tubular port carrying member or valve casing 29 rigidly supported thereby, as clearly shown in Fig. 3.

Formed integral with the casing 28 and projecting downwardly so as to form an inner compartment with the member 2 and f a portion of the channel 8, are the two parallel disposed semi-annular rims '30 and'30,

respectively, each one of which is provided with a packing strip .31 disposed to engage the abutting Wall of the member 2 and thereby prevent any leakage of said connection.

The tubular valve casing 29 is provided with the oppositely disposed exhaust ports 34 and 35 and with the centrally disposed main exhaust port 32which is disposed to at all times conduct the water from either side of the piston from the piston chamber G into the chamber formed between the projections 30 and 30 to the outlet conduit or port 33 and finally through the port or other suitable conduit 34.

The tubular valve 36 which is disposed for reciprocatory movement within the tubular valve casing 29, is formed to have the main exhaust chamber 36' and the oppositely disposed chambers 40 and 40, respectively. The port 37 disposed centrally of the chamber 36' of the valve 36 is at all times in register with the port 32, while either one of the ports 34 or 35 are so positioned and formed as to be. in register one at a time with its respective port 34 or 35 of the tubular valve casing 29. These ports 34 and 34 and 35, 35 constitute the outlet or exhaust ports from the ends of the chamber C through the valve and finally out of the eduction conduit 34. i

The respective intake, more properly speaking, water conducting chambers 40 and 40"are provided with the respective intake ports 41 and 41 which are disposed to be placed one at a time in register with the introducingchamber 44 of the member 3, the port 45 leading the water from the hose connection or other conduit 46 into such chamber 44. .Thus when the valve is in the position as shown in Fig. 3, the water will he conducted from the conduit 46 into the 'chamber 44 and through the port 41 of the valve 36 into chamber 40 through the concentric port 43' in the end of the chamber 40' and finally upon the pressure side of the piston, to move the piston in the direction of the arrow Fig. 3, while the valve being in the position as shown in Fig. 3, the water upon the non-pressure side of the piston will be forced through the ports 34 and 34 into the chamber 36' and finally through the ports 37 and 32 into and out of the exhaust port 33 and conduit 34. The chamber 40 of the valve 36 is provided with. the intake port 41 and the concentrically disposed recting port 43, so that when the port4l is in register with the chamber 44, the water will be directed in the opposite direction to that shown in Fig. 3, to impart an opposite movement to the piston and shaft 6.

Each of the respective chambers 40 and 40 are sealed by the shouldered rings 42 and 42', which alsoprovides an abut-ting means for the terminals 26 of the respective springs 25 as will later appear.

-In order to prevent the rotation of the tubular valve 36 within the support 29, a pin 47 is carried by the valve casing 29 and alines with an aperture in the shouldered ring 42 of the valve, while in order to normally hold the valve 36 in the Position as shown in Fig. 3, so that when water is conducted through the motor, the piston will have imparted thereto a movement to start in proper operation the valve, the spring 48 has its respective terminals 49 and 50 connected to the projection 30 and the shouldered ring 42 of-the valve.

In order to properly support the motor casing, preferably so that the chamber C is horizontal position, although it is to be understood that the same may be operated in a vertical position, the supports 51 are connected as shown in Fig. 1' and provide a proper mounting for the motor.

From the foregoing description taken in' connection with the drawings, it is evident that the operation of the present motor is readily understood, but briefly stated it is as follows: Presuniing the parts to be in the position as shown inFig. 3, and the water entering through the conduit 46 into the chamber 44, and the piston being nearer the end 42 of thevalve 36, the water will enter the port 41 of the valve 36 and through the concentric port 43 into the chamber C. This action will move the piston and shaft in the direction of the arrow Fig. 3, while the water upon thenon-pressure side of the piston will be forced by the piston to pass through the ports 34 and 34 of the casing 29 and valve 36 into the casing 36 of the valve and finally exhaust through the ports 37 and 32 and through the outlet conduit 34, of the lower member 2. As the piston approaches the valve side of the motor, the terminals 26 of the spring 25 nearest the end 42 of the valve 36, will engage said end 42 and move the valve in an opposite direction, thus reversing the flow of water so that the pressure will be placed upon the opposite side, that is so that the ports ll of the valve 36 will be placed in communication with the casing or chamber 44 and thereby conduct the water through the concentric port 42 in the end of the valve to impart an opposite movement to the piston and shaft 6. The water from the non-pressure side of the said piston being forced through the ports 35 and 35 of the casing 29 and valve 36 into the chamber 36 I of the valve and out of the ports 37 and 32 through the eduction conduit 34.

By reason of the spring 48, should the flow of water be turned off to stop the motor, the valve 36 will normally assume the position as shown in Fig. 3, so that pressure will be admitted to one side of the piston, and thereby impart the desired movement and start into operation the valve'36 so that a continuous reciprocatory movement is imparted to the valve 36 while the piston and shaft 6 are being oscillated.
