ROBERT A. KELLY AND GEORGE N. KELLY, 0F PETERSBURG, ILLINOIS, ASSIGNORS TO NELLIE G. WHITE, OF PETERSBURG, ILLINOIS.

STICKER-ROD CLUTCH.

Application filed March 3, 1913.

T all whom it may concern Be it known that we, ROBERT A. KELLY and GEORGE N. KELLY, citizens of the United States, residing at Petersburg, in the county of Menard and State of Illinois, have invented new and useful Improvements in Sucker-Rod Clutches, of which the following is a specification.

This invention relates to improvements in pumping apparatus and one of the objects of the invention is to provide a unitary pump whereby hard and soft water, or other liquids of difierent character may bepumped and maintained in separated relation.

In the preferred embodiment of our invention we employ a pump base, having separate chambers to which the pumps for the different liquids deliver, and from which chambers piping may extend to deliver the separate liquids at desired points.

The further object of our invention is to provide devices for coupling the pump rods with reciprocating actuating members in such a manner as to provide for automatic uncoupling of the pump rods at predetermined times so as to throw any of the pumps out of action while the actuating members therefor are in operation, this feature of our invention being especially useful where a windmill is used.

In cases where tanks are employed for the liquids of difierent character, our invention contemplates the provision of pressure control devices for coupling and uncoupling the pump rods with their actuating members.

Other features of novelty will be more fully described in connection with the accompanying drawing and will be more particularly pointed out in and by the appended claims. r

In the drawing, Figure 1 is a view in elevation, with parts in section, illustrating one embodiment of our invention with a windmill as the motor. Fig. 2, is an enlarged View of one of the coupling devices with parts thereof in section. Fig. 3, isa plan view in elevation of the pump base. Fig. 1, is a sectional view thereof on line 4.t of Fig. 3.

Like characters of reference designate similar parts throughout the diflerent figures of the drawing.

Throughout the description of the specific form of my invention herein illustrated,

Specification of Letters Patent.

we will designate parts belonging to one group or set of mechanism with reference to their utility for pumping hard water and the remaining set of elements will be designated as soft water pumping elements, it being understood that such arbitrary designations are for convenience in distinguishing one group of elements from the other, for while the device of our invention is especially adapted for pumping hard and soft water its utility is not limited in this connection as it may be used under any conditions where it is desired to pump liquids of difierent character,and more especially, where it is desired to maintain the pumped liquids entirely separate from each other.

Referring more specifically to the con struction shown, 1 designates the lower portion of a windmill having actuating members in the form of reciprocating rods 2 and 3. Wires or like throw out elements 4 and 5 are provided for throwing the windmill into and out of the wind. The ground line is indicated at 6 and hard and soft water tanks 7 and 8, respectively, are shown disposed on opposite sides of the windmill. A well portion in the earth is indicated at 9, and a cover plate 10 serves to close the open end thereof and provide for suitable bearings and supports, as will hereinafter more fully appear.

The apparatus embodying our invention is shown disposed in the well portion 9, and a pipe 11 may lead to a cistern as the supply of soft water, while a pipe 12 may lead to a well as the supply of hard water. A soft water pump is indicated at 13, and may comprise a cylinder having a pump piston 1%, connected with a pump rod 15. The soft water pump 13 is connected with one chamber 16 of the pump base 17 for discharge thereinto. The connection of the pump 13 may beeffected at 18, by means of the threaded opening thereat, and the pump rod 15 may extend through the chamber 16 and through a suitable stuffing box 19, mounted in threaded opening 20. A partition 21 divides the base 17 into separate chambers 16 and 22, the former being the soft water chamber and the latter the hard water chamber.

, A hard water pump is indicated at 23 and chamber 22, and has a pump rod 24 which extends through a stufiing box 25, the latter being mounted in opening 26, and the pump 23 being connected at opening 27.

A valved surface soft water draw off pipe 28 is mounted in the cover plate 10 and is connected with chamber 16 at 29. A similar hard water draw oif pipe 30 communicates with the hard water chamber 22 at 31. A soft water tank supply pipe 32 is connected with chamber 16 at 33, and discharges into tank 8. A float controlled valve 34 may be provided on the end of pipe 32 to shutoff discharge into tank 8 when the latter becomes filled, and to permit discharge thereinto when the water level therein descends below a predetermined point.

A tank supply pipe 35 is connected with chamber 22 at 36, and discharges into, tank 7. A float controlled "alve, or any other suitable automatic means, may be provided to close pipe, 35 when thelevel in tank 7 reaches a predetermined, point, and serving to open pipe 35 when the level descends.

A soft water pressure control cylinder 37 is mounted on. base 17 andcommunicates with chamber 16. Said cylinder is provided with a plunger 38 having a plunger rod 39 connected with aweighted. arm 40. Arm 40 is pivotedtoa standard 41. at 42, and is also connected with wire 5. A similar arrangement is provided for chamber 22 to which a pressure control cylinder 43 communicates, the same having a plunger rod 44 connected with weightedarm 45. Arm 45 is connected with standard 41 and also with wire, 4, as clearly shown in Fig. 1.

When the valves of either of. the pipes 32 or 35 are closed by reason of the levels in the tanks reaching a pre-determined point, the resulting increase of pressure in the chambers 16 or 22 will force the plunger rods 39 or 44 upwardly to throw the windmill. or other motor out of action.

We will next describe the manner in which the pump rods 15 and 2.4 are coupled and uncoupled with and from the windmill actuating or reciprocating rods 3 and 2, respectively. As the coupling device is the same for both sets of mechanism, only one need be described in detail.

Referring more particularly to Fig. 2, 46 designates, a guide yoke which is secured to pump rod 24 and which loosely embraces and guides the mill or motor actuated rod 2. A spring 47 is fixed to the guide yoke 46, and carries at its upper end a collar 48 which loosely embraces the pump rod 24 and the motor rodi2. A coupling pin 49 is fixed to the collar 48 and is adapted to project, through openings 50 and 51, in the rods 24 and 2, respectively. In the position shown in Fig. 2, the constantly moving or reciprocating rod 2 of the motor or windmill is shown coupled with the pump rod 24 because at this time the storage tank would not be completely full. Upon the level in such storage tank reaching a predetermined point, the resulting increase of pressure will elevate the rod 44, and the latter being provided with a cam 52, it will thus be seen that such cam will engage and shift the collar 48 from the full line to the dotted line position, as shown in Fig. 2. This movement of the collar 48 withdraws the pin 49 from the opening 51 and thereby serves to uncouple the rods 2 and 24, the former being permitted to freely reciprocate without actuating the latter. Upondescent of the level in the tank the pressure in the pump case 17 will decrease and the weighted arm. 45 will assist in lowering the rod 44 from the dotted line position shown in Fig; 2, to the full line position shown therein. Thus the cam 52 will release the collar 48, and the spring 47 will return the collar 48 and the pin 49 from the dotted line to the full lineposition, assoon as opening 51 registers with opening 50.

It is believedthat the operation will be clearafrom the foregoing and need not be recapitulated and it will also be clear that we have provided a unitary structure for simultaneously or singly pumping separated liquids which may be hard and soft water. It will further be seen that we have provided liquid pressure control devices for operating coupling devices to couple and uncouple the pump rods with and from the motor rods or actuating members, i 7 A By connecting the pressure control cylinders with. the pump case, so as to effect di rect communication between the separate chambers of the pump case and the respective control cylinder thereof, we provide a quickly responsive pressureactionfor causing operative connection and disconnection of the pumprods with-their actuating rods.

Thepump case with its divided chambers, by reason ofthe fact that itvis the connect ing member between the two sets of apparatus, forms a uniting element which not only greatly simplifies the mounting of the two sets of apparatus but also simplifies the operation thereof, and at the same time maintains said sets of" apparatus entirely distinct and independent as regards the manipulation of the liquids-passing therethrough.

While we have herein shown and described one specific form of our inventionwe do not wish to be limited thereto except for such limitations as the claims may import.

Having thus described our invention, what we claim is 1. A device of the character described comprising two members mounted for reciprocatory movement, the adjacent extremities thereof being disposed in overlying relation, said overlying portions of the members being provided with openings adapted to register, a collar loosely surrounding the overlying portions of the members, a resilient connection between the collar and one of said last two mentioned members, a yoke carried by the last mentioned member through which the second of the last two mentioned members is loosely di rected, a pin carried by the collar adapted to be disposed through the openings of the members when in register, a third member mounted for reciprocatory movement, and means carried by the third member coacting with the collar for adjusting the pin into a retracted position upon movement of said third member in one direction independently of the first named members.

2. A device of the character described comprising two members mounted for reciprocatory movement, the adjacent extremities thereof being disposed in overlying relation, said overlying portions of the members being provided with openings member adapted for engagement with the 35? collar upon movement of the third member in one direction independently of the first mentioned reciprocating members in order to adjust the pin in a retracted position.
