lIUGH W. KIhIES, OF DAYTON, OHIO, ASSIGNOR TO VAILE & RIMES, A FIRM COMPOSED OF JOHN H. VAILE AND HUGH W. KIMES, OF DAYTON, OHIO.

FLUID-MOTOR.

Patented Sept. 17, 1907.

To all whom it may concern:

\ -.4. -Be it known that I, Hun-n W. Krnss, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Fluid-Motors, of which the following is a specification.

- -My invention relates; to agduplexinotor and pump each being self-contained and independently attached 4 upon a common base; whereby alternate mounting of motor or pump is permissible, likewise permitting. a change of pump-of larger or smaller capacity without disturbing the position of motor or base, rendering all the parts interchangeable.

Another object of my invention relates to the construction of the motor, pump and base so as to insure perfect alinement of the parts in assembling, all being of universal construction eliminating the adjustments of a particular motor or pump to a particular base.

. Another object of my invention is to provide the motor valves with cup-shaped packings mounted in their ,peculiar manner, forming a balanced valve, :insuring free movement of the valve without any lateral strains. Another object of my invention relates to the construction of thepump air chamber, enabling the pipe connection between the pump aiid governor to be made in a convenient and readily detachable manner.

Another object of my invention is to construct valve cylinder linings with ports through which the driving fluid is directed by the movement of the valves.

Various other features of my invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which:-

Figure 1 is a vertical sectional view through one of the I motor cylinders and valves, one pump cylinder and air chamber, and through the governor: Fig. 2 is a perspective view of one of the valve cylinder linings. 3 is an enlarged central horizontal section through motor valve andcylinders. Fig. 4 is a central horizontal section through motor pistons and their contained cylinders. Fig. 5 is a section on line 2:, :r, Fig. 1.

Fig. 6 is a. top plan view of the motor chests. Fig. 7 is a top plan view of the distributing chests located between the valve chests and piston chests. Fig. 8 is a section on line 14), 10, Fig. 1. Fig. 9 is a section on line y, y, Fig. 1. Fig. 10 is a section on line 2, 2 Fig. 1.

The valve and piston rod connections, and the distributilig chest for so directing I he energizing fluid that the right hand piston controls the left hand valve, and

vice yours, are fully descrihxd in an application filed by me September 19th. 1905, Serial No. 279,193. Likewise the governor herein shown controlling the fluid pressure 'to the motor and in connection with the pump pressure for automatic control thereof, is fully described in Patent No. 813,008, issued to me dated February 20, 1906. The herein shown combined motor and pump, together with its automatic control are primarily adapted for household purposes, iifwhich the fluid pressure is water in connection with the city mains for operating the motor, and the pump is in connection with a cis- 'torn for pumping the cistern water through the house supply pipes. It is therefore desirable that the con-. sttuction be of such character as to be simple, and effective, with but few working parts and compactly ar-. ranged as the outfit is usually in the hands of mechanically inexperienced persons.

The device is automatic in its operation, it being at- I rest for a period of time and operating when the supply is being used, it is therefore essential that the workings of thedevicebe positive in order to make the same available. Further the cost of construction must be such as to make the machine salable.

These supports3, 4, are identical in dimensions, in the same alinement and project above the marginal rim 7 of the base. This enables a series of bases to be finished in one operation and effecting proper alinement in mounting themotor and pump. i

The piston rod 1 1 is similarly connected with the valve rod 35. 64 representsa pin fixed to bar and riding in ,a slot in the lever (i5, pivotally supported upon the shaft 66 represents a connecting link, having pivotal engagement with the lever and valve rod 35 for actuating the rod 35.

The construction'of the pump is as follows:-67 represents the piston chest provided with duplex ' cylinders 79, 71, within which the pistons 72, 73, slide respectively and being in connection with' the piston rods 13, 14, of the motor. These pistons are of similar construction as the pistons of the motor, and provided with similar cushioning devices 74, adapted .to contact with the smiling box nuts. represents an inlet chamber towhich the inlet pipe 76 is connected. 77- represents a series'of valves controlling a series of ports leading into the chamber 75 and opening respectively into the forward and rear chambers 78, 79, of each cylacting, that is, drawing water from the chamber 75 into the chamber 79', in the forward and reverse movement of the piston, that is, when the piston moves forward it is drawing water from chamber 70 into the r Y 1 passage 78 and forcing the same through passages 79 into chamber 82, lifting valve 80, and through outlet passage-55.. The rearward action dmwing water from chamber 70 into chamber 79, and forcing the water from chamber 78 into the chamber 82 and out into the service passage 86. lfhese passages 85 and 86 being connected to a suitable tank under pressure, which pressure in such tank controls the working of the governor, hereinafter to be .ciescribed. I

87 represents a. downwardly projecting boss from the central portion of the shell 84, provided with a bore 88. This boss projects below the water line oi'the air chainber of the pump and the bore forms a passage for the water under pressure to be carried through the pipe 89 to the governor 90. Thus as tlrepressurc-irom pipe 89 is exerted against the piston-91, and when it becomes greater than the pressure oi the water in passage 92, forming the motor supplyfund tho.combined spring tension against the piston 91, it will close the port 93,

by means of the valve 94 in connection with the piston- 91, seating upon the seat of the passago 93, and as the pressure against the piston illl'iwcomcs less than the motor service pressure, the combined action oi the automatic control of motor .and pump andstorage tank supply -is maintained 95 represents a connecting rod connected with inotor,
