WATER-MOTOR.

Specification of Letters Patent.

Patented Apr. 18, 191%..

Application filed August 16, 1915. Serial No. 45,786.

To all whom it may concern:

Be it known that I, SAMUEL H. CARBIs, a citizen of the United States, residing at Freeport, in the county of Armstrong and State of Pennsylvania, have invented a new and useful VVater-Motor, of which the following is a specification.

The present invention appertains to fluid motors, and relates more particularly to water motors, it being the object of the invention to provide a novel and improved water motor for washing machines, although the motor may be used for various purposes.

It is the object of this invention to provide a water motor consisting of but few parts, and which is simple and inexpensive in construction, without jeopardizing the utility and efliciency of the motor.

A specific object of the invention is the provision in a water motor of novel means for controlling the valves which control the inlet and outlet of the water at the opposite ends of the cylinder.

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 the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a plan view of the motor as applied to a washing machine. Fig. 2 an enlarged longitudinal section of the motor taken on the line 22 of Fig. 1. Fig. 3 is a still further enlarged longitudinal section of the motor taken on the line 3-3 of Fig. 2. Fig. 4 is a reduced cross section taken on the line 4l4: of Fig. 3.

In carrying out the invention, there is provided a cylinder 1 having one end closed and the other end open, and a head 2 is secured to the open end of the cylinder. The cylinder and its head are each in the form of a casting, although they may be constructed'in various manners, and the head 2 is provided with a central outstanding sleeve 3 through which the piston rod or stem 4 1s slidable. That portion of the piston rod 41 within the cylinder 1 is reduced in diameter, as at 5, and this provides a shoulder 6 movable within the sleeve 3 when the piston rod is reciprocated. The inner end of the piston rod is threaded into the piston 7 which works within the cylinder 1, and the piston 7 is provided with an integral collar 8 proecting centrally therefrom and embracing the reduced portion 5. A rubber, fiber, or other suitable packing ring 9 embraces the plston 7 and is held in place thereon by a wire or equivalent band. 10 embracing the packing ring.

The outer protruding end of the piston rod 4: is provided with a reduced threaded extension 11 onto which one end of a rack 12 is adapted to be threaded, whereby said rack can mesh with a pinion 13 secured to the upper end of the agitator staff 1 1 of the washing machine, as suggested in Fig. 1. The motor may be attached to the washing machine in any suitable or well known manner, whereby the reciprocation of the piston rod 4: and rack 12 will serve to alternately rotate the stafi or shaft 1 1 in opposite directions.

The free end of the sleeve 3 has a stuiiing box 15 containing a packing 16 embracing the piston rod 4, and a gland 17 is threaded into the stuffing box for compressing the packing, to prevent leakage.

Thehead 2 is provided with diametrically opposite intake and exhaust chambers 18 and 19, respectively, at the opposite sides of the sleeve 3, and the head is provided with integral nipples 20 and 21 forming inlet and outlet ports for the respective chambers 18 and 19. The nipple 20 can be connected by a hose 20 to a faucet or other source of water, and the discharge water can be delivered from the nipple 21 through a hose 21 applied thereto to a sink, drain, or the like. The head 2 is provided with a pulsating chamber 22 of arcuate formation passing partially around the sleeve 3 and having its ends disposed adjacent the ChilIIbbers 18 and 19. The head 2 has restricted openings 23 and 24: between the. respective chambers 18 and 19and the ends of the chamber 22, and has restricted openings 25 and 26 between the respective chambers 18 and 19 and the interior of the cylinder 1. The openings 23 and 25 are in alinement, as

well as the openings 24: and 26, and the axes of the two pairs of openings are parallel with the axis of the cylinder. A bushing 27 is threaded into the opening 25 from the inner side of the head 2, and provides a valve seat, and the outer side of the head is provided with an opening28 in alinement with the opening 24, a screw plug 29 being threaded within the opening 28 for normally closing the same.

A double puppet valve 30 is disposed within the intake chamber 18 and has oppositely extending guide stems 31 and 32 working slidably within the opening 23 and bushing 27, respectively, to guide the valve 30 for reciprocatory movement. The valve 30 is seatable against the partition between the chambers 18 and 22 for closing the opening 23, and is seatable against the bushing 27 for closing the passage through said bushing leading to the interior of the cylinder. A puppet valve 34 is disposed within the chamber 22 for controlling the opening 24, and has a guide stem 35 passing slidably through the openings 24 and 26 to guide the valve 34 for proper reciprocatory movement. The stem 35 has a reduced extension 36 projecting into the cylinder, and a second puppet valve 37 is fitted upon the extension 36 and is secured thereon by means of a pin or other securing element 38. The valves 34 and 37 thus cooperate to provide a double puppet valve for controlling the openings 24 and 26 leading from the chamber 19 to the chamber 22 and interior of the cylinder, respectively. The valve 34 is seatable against the partition between the cha1nbers 19 and 22, and the valve 37 is seatable against the partition between the chamber 19 and the interior of the cylinder. The inner end of the stem 32 has a reduced extension 33 projecting into the cylinder 1 and corresponding with the extension 36.

The double puppet valves are operated by the movement of the piston rod 4, and to this end, a yoke or plate 39 is mounted slidably upon the reduced portion 5 of the piston rod and its end portions slidably embrace the extensions 33 and 36 of the double puppet valves. Cotter pins or other retaining elements 40 and 41 are engaged to the free ends of the extensions 33 and 36 respectively, for holding the yoke 39 slidably upon said extensions, and to prevent the dis placement of the yoke upon the piston rod. A pair of spiral springs 42 and 43 are disposed upon the opposite sides of the yoke 39 and have their larger ends riveted or otherwise secured to the yoke, while the smaller ends of the springs which project in opposite directions slidably embrace the re dueed portion 5 of the piston rod. The shoulder 6 of the piston rod 4 is movable against the spring 43 when. the piston 7 is moved away from the head 2, and the collar 8 of the piston or shoulder formed thereby is movable against the spring 42. The yoke 39 has limited sliding movement upon the extensions 3.3 and 36 of the puppet valves.

The cylinder 1 is provided at one side with a longitudinal bypass or passage 44 opening at one end, as at 45, into that end of the cylinder remote from the head, While the other end of the passage 44 communicates with a passage 46 with which the head 2 is provided, said passage 46 communicating with the intermediate portion of the pulsating chamber 22.

The operation of the motor is as follows :Supposing water under pressure is supplied through the nipple or intake port 20 to the chamber 18, with the puppet valves arranged as illustrated in Fig. 3, the water would flow from the chamber 18 through the opening 23 into the chamber 22, and from thence through the passage 4644 into that end of the cylinder remote from the head 2, it being noted that the double puppet valve 30 is seated against the bushing 27 to close the opening 25. The valve 34 is seated to close the opening 24 while the valve 37 is unseated, to allow the water between the piston 7 and head 2 to pass through the opening 36 into the chamber 19 and thence out through the nipple or outlet port 21, when the piston 7 is forced toward the head 2 due to the water entering the cylinder behind the piston from the passage 4644. Now, when the piston moves toward the head, the collar 8 of the piston strikes the smaller end of the spring 42, whereby the yoke 39 is moved yieldably by the piston toward the head 2, and when the yoke 39 has moved slightly upon the extensions 33 and 36, it will move the double puppet valves outwardly, thereby seatin the valve 37 to close the opening 26, and unseating the valve 34. Now, the water from the chamber 18 will pass through the bushing 27 into the cylinder at the head end thereof, to force the piston away from the head 2, and the water within the cylinder between the piston 7 and closed end of the cylinder will be forced out through the passage 46-44 into the chamber 22 and thence through the opening 24 and chamber 19 to the nipple or port 21. When the piston 7 reaches that end of the cylinder remote from the head 2, the shoulder 6 of the piston rod 4 strikes the spring 43 and moves the yoke 39 away from the head 2 until the yoke 39 strikes the pins 40 and 41 to thereby restore the double puppet valves to the position illustrated in Fig. 3. The above operation is then repeated, it being noted that the reciprocation of the piston rod serves to operate the double puppet valves properly to alternate the inlet and discharge of Water at the opposite ends of the cylinder whereby the motor will operate quickly and effectively. The spring 43 when in the position illustrated in Fig. 2 is not effective to resist the movement of the yoke 39 by the spring 42, the smaller end of the spring 43 entering the sleeve 3.

The motor is comparatively simple and inexpensive in construction, eificiently serves its purpose, and is not liable to get out of order easily. The other advantages and attributes of the motor will suggest themselves to those skilled in the art Without further comment being necessary.

Having thus described the invention, what is claimed as new is:

A motor comprising a cylinder having a head provided "with an outstanding sleeve, intake and exhaust chambers a pulsating chamber, openings between the intake and exhaust chambers and pulsating chamber, and openings establishing communication between the interior of the cylinder and the intake and exhaust chambers, the cylinder having a passage establishing communica tion between the pulsating chamber and that end of the cylinder remote from the head, a piston working Within the cylinder and having a piston rod sliding through said sleeve, a pair of double puppet valves controlling said openings and having stems tt'epiee of thin patent may be obtained for five cents each, by afldretaflng the Commissioner of Patents,

projecting into the cylinder, the portion of the piston rod Within the cylinder being reduced in diameter and providing a shoulder, the piston having a collar embracing the piston rod, a yoke slidable upon the reduced portion of the piston rod and slidably engaging said stems, and spiral springs having their larger ends secured to the yoke at the opposite sides thereof and having their smaller ends slidably embracing the reducedportion of the piston, said shoulder and collar being arranged to move against the respective springs when the piston reaches the opposite ends of the cylinder whereby the puppet valves are operated.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
