PUMP.

Specification of Letters Patent.

Patented May 5, 191 1:.

Application filed January 17, 1913. Serial No. 742,638.

To all whom it may concern Be it known that I, CATEN J. UHLARIGK, a citizen of the United States, residing at Big Sandy, in the county of Chouteau and State of Montana, have invented new and useful Improvements in Pumps, of which the following is a specification.

My invention relates to pumps and has for its principal object the provision of a double acting force pump which may be operated manually or by mechanical power.

A further object of my invention is to construct my pump with such regard for proportion, number and arrangement of parts, as will make it effective in its operation, durable and cheap to manufacture.

A still further object is to so arrange the various working parts of the pump in their relation to each otherthat there will be a continuous and unbroken stream of water issuing from the mouth of the pump, during the operation of the pump.

The above and additional objects are accomplished by such means as are shown in the preferred embodiment in the accompanying drawings, described by the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this specification.

In the drawings, Figure 1 is a front elevation of my pump, shown with the various parts in assembled relation to a well. Fig. 2 is a side elevation of the driving mechanism of the pump. Fig. 3 is a sectional view, showing the construction of the valves and interior portion of the pump cylinders. Fig. 4 is a detail view of the fly wheel carried by the main drive shaft. Fig. 5 is a top-plan view of one of the piston heads.

Referring now to the drawings, throughout which like numerals designate corresponding parts, in the several views; the general embodiment of my invention 1ncludes the discharge pipe, the driving mechanism for the pistons and the pump cylinders.

The discharge pipe 1, as illustrated in the drawings, is a length of ordinary piping, the lower portion of which is projected through an opening in the top of the well cover into the well proper. The upper end of this discharge pipe carries the discharge spout 2, which is of the construction customary to pumps of this class. This discharge pipe is securely held in its operative position by means of a collar 3, and the arms 1-, carried thereby. Mounted on the discharge pipe in termediate the well cover and the upper end of the said pipe is a collar 5, having the integral, angular bracing legs 6, which are offset adjacent their ends, as at 7 and are secured to the well cover 8 through the medium of the bolts or screws 9. This collar member 5 is provided with the angular shaft supporting arms 10 which are equipped with the bearing boxes 11 at their free ends. The pipe 1 is further provided with the collar member 12, disposed around the pipe intermediate its lower end and the well cover. A pair of angularly and downwardly projecting shaft supporting arms 13, having bearing boxes 14, similar to the members 11, are secured to the said collar 12 at diametrically opposite points. I

The driving mechanism of my pump includes the crank shaft 15 provided with the terminally mounted wheels 16 and the spaced collars 17, the latter members being disposed to prevent lateral movement of the shaft 15 through the bearing boxes 11. A gear wheel 18 is keyed to the shaft 15 and is operatively connected to a similar gear wheel 19, mounted on the shaft 20 through the medium of the link chain 21. The shaft20 is journaled in the bearings 14 and is provided with the collars 22, similar in function to the members 17, and is further provided with the terminally mounted drive wheels 23. These wheel members 23 are concentrically mounted and carry the eccentrically positioned connecting pins 24. The pistons 25 are operatively connected to the drive wheels 28 by the pivotally mounted driving arms 26.

The pump cylinders, which are designated as a whole by the numeral 27, are similar in construction and in the performance of their functions and I shall, therefore, describe only one of them. This pump cylinder consists of a cylindrical casing 28, having the reduced centrally bored neck 29 at its upper end, and the internal screw thread 80 at its lower end. The conducting pipe 31 is screw threaded into the lower end of the cylinder. This conducting pipe 31 is enlarged at its upper end to produce the internal shoulder 32, whereon is mounted a flap valve 33. The piston rod 25 is slidably mounted in the central bore of the neck 29 and carries at its lower end the piston head. This piston head is a substantially open ended cylindrical casing 34:, having the cross bars 35 at its upper end secured to the lower terminal of the piston. A pivotally mounted flap valve 36 is seated on the upper face of the internal annular flange 37, formed integral with the piston head. Adjacent its upper end, the cylinder casing 28 is provided with the internally screw threaded escape port 88. A T joint 39 is screw threaded to the lower end of the discharge pipe 1, and is connected to the ports 38 by the pipe lO. The pipes 40 are provided with bearings t1 and 4-2, the former of which is screw threaded to receive the valve supporting rod A pair of swingingly mounted gates 44: and 45 are carried centrally of the shaft and are disposed to alternately close the mouths as and d7 of the pipes t0. The wheel 16 carries a handle 48.

From an inspection of Fig. 3 it will be readily seen that after the pipes $0 have been threaded into the arms of the coupling 39, that the rod i3 is passed through the bearing 4:2 and has its threaded end passed through the threaded bearing 1-1. T 1e valves l l and can now be passed into the coupling 39 through the upper end of the coupling and pivotally connected with the rod L5 by suitable pivot pins so that the valves may swing upon the rod and move into and out of engagement with the inner ends of the cmipling arms in which the pipes 40 are placed. These valves when resting in their lowered positions will prevent liquid from flowing through the pipes 40 back into the pump cylinders. hen it is desired to reach the valves for any purpose whatever it is simply necessary to remove the pipe 1 and the valves "an then be removed by inserting the hand through the opening in which the pipe 1 fits and withdrawing the pivot pins. The rod can then be easily removed. This rod in addition to forming the supporting means for the valves also constitutes a transverse brace which will remove strain from the threads of the pipes -l0 and coupling arms 46 and 47 and will therefore prevent danger of leakage.

From the above disclosures, it will readily be seen that I have provided a double acting, lift pump which will be effective in its operation and is formed of a relatively small number of parts.

I desire to call particular attention to the function of the members 45, which operate to prevent the water from passing from one pipe 5L0 into the other instead of going up the pipe 1.

Having thus described my invention, what I desire to claim and secure by Letters Patent, is

1. In a pump a plurality of cylinders an outlet pipe, a coupling mounted upon the lower end portion of said outlet pipe and provided with inlet arms, connecting pipes leading from said cylinders and having their upper ends extending into the inlet arms of said coupling, a rod extending through said last-mentioned pipes and through the arms of said coupling, said rod serving as ameans for bracing said pipes, valves mounted in said coupling and pivotally connected with said rod and adapted to move into and out of position to close the inner ends of said arms and prevent fluid from flowing from said outlet pipe back into said cylinders, and means for drawing fluid into said cylinders and forcing the same through said pipes into said coupling and through said outlet pipe.

2. In a pump a plurality of cylinders, an outlet pipe, a coupling carried by said outlet pipe and provided with inlet arms, pipes leading from said cylinders and having their upper ends connected with the branches of said coupling, a removably mounted bracing rod extending through the upper end portions of said branch pipes and through the arms of said coupling, and valves positioned to close the inner ends of the arms of said coupling pivotally connected with said rod.
