PUMP.

SPECIFICATION forming part of Letters Patent No. 256,950, dated. April 25, 1882.

(Model.)

To all whom it may concern:

Be it known that we, JOHN BEAN and Ros- COLE BEAN, of Springfield, in the county of Clarke, and in the State of Ohio, have invented certain new and useful Improvements in Pumps; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to certain novel parts and combinations of parts in pumps, which will be fully understood from the following description, when taken in connection with the annexed drawings, in whiel1- Figure 1 is an external View and elevation of one side of our improved pump complete. Fig. 2 is a vertical section through partsof the pump, taken in the plane indicated by dotted line :10 00, Fig. 7. Fig. 3 is a side elevation of the complete pump as seen by lookiugatit from the discharge-pipe side. Fig. 4 is a vertical section through the pump, taken in the plane indicated by dotted lines y 3 on Fig. 7. Fig. 5 is a side elevation of those parts of the pump which are to remain stationary in the well. Fig. 6 is a side elevation of those parts of the pumpwhich can be detached from those parts which are shown by Fig. 5 and removed from the well. Fig. 7 is a top view of the pump complete. Fig. 8 is an elevation of the air-chamber sand-pipe, the valve therefor,and connections with the suction-tube. Fig. 9 is an elevation of our suspension-frame for supporting the working'parts of the pump, and Figs. 10 and 11 show the working parts of our pump.

A designates the platform or foundation flange of the pump, which we construct of tn 0 parts, ab. The part'ct is a semicircular flange, or one-half of a ring, and the part bisformed of a corresponding semicircle, which abuts joints with a, and a circular portion, which overlaps the part a and is secured to it by a screw or other means. The part a is intended to be secured in a suitable manner to the curb or top of the well, and from this part depend two pipes, B B, which are closed at their upper ends and serve as air or vacuum chambers. Instead of pipes, solid suspending rods may flange, 0, internally and near its upper end,

which flange is preferably dished toward a central opening through it, and it has a small leak-hole,d, through it, for a purpose hereinafter explained.

D designates the suction-pipe, which passes 1 through the bottom of the cylinder O and ex-;

tends up through the opening in the center of the flange 0, lcavinga space between its upper end and the inner edge of said flange, as shown in Figs. 2 and 4. Below the cylinder 0 the suction-pipe D is sealed by a diaphragm, D, and above and below this diaphragm are short horizontal pipes D D which establish com munication between the said suction-pipe and a sand-box,E, which is provided with a wedgeshaped discharging-gate, E, at its lower end, that may be raised or depressed from the top of the well by means of a rod, E It will be seen by reference to Fig. 1 that the lower end of the sand-box E is curved laterally, so that the said gate can be opened and shut by a vertical movement. Other means may be adopted for applying a discharging-valve to the said box and operating the valve. A reticulated strainer, E in the sand-box operates to check the upward flow of the sand with the water while passing from that part of the suctionpipe below the diaphragm D, through pipes D D ,into that partof the suction-pipe above the diaphragm.

F designates a tubular air or vacuum cham sand-box E, and which is hermetically sealed at its upper end. This air or vacuum ehamberis especially useful for pumps used. in driven wells her, which is secured to the upper end of the and where the suction-pipes are very long and the pump-plungers work hard. In such cases the partial vacuum which is produced in the tube F during the ascent of the plunger will react, and thus assist in raising the water. There will of course be an air-chamber of greater or less capacity in the tube F at all valve-piston G works, connected to the pumphandle G by means of a rod, G (Shown in Figs. 2 and 4.) The lower end of this cylinder G has applied to it a valve, 6, opening upward, which is designed for closing the upper end of the suction-pipe and the opening surrounding this pipe, but which does not close leak-hole d. Thelower endoi'the pump-cylinderGis slightly tapered and packed, so that while it can be made to fit water-tight into the upper flaring end of the wall of cylinder 0 it can be removed from this cylinder, as will behereinafter explained. The upper end of the pnmpcylinder G is closed permanently or by a removable flanged cap, H, which is suitably packed, and which may be connected to the cylinder by a bayonet or other suitable positive fastening. From the center of the cap or cylinder-head H rises a pipe, H, the interior diameter of which is one-half the interior diameter of the pump-cylinder, and in this pipe H is applied a lon piston, which may be hollow or not, and which is rigidly connected to the pistonrod G so as to move up and down with the valve-piston G, and to descend into the pumpeylinder at each do wnstroke. By this arrangement of parts it will be seen that a continuous flow of water is caused to pass through the discharge-pipe I by reason of the long piston displacing a quantity of water in the cylinder during the descending strokes.

It should be stated here that the piston or bucket G is perforated and provided with a flexible disk-valve, It, which will allow any water remaining in the discharge-pipe I, when the bucket G is stationary, to slowly pass under it and descend through the small leak-hole d into the cylinder 0, thus preventing water from freezing in the pump. The disk-valve h is made very thin and should not extend to the bore of cylinder G. The operation of this valve will then be as above described.

J designates a tubular air-chamber, which communicates at its lower end with the pumpcylinder G, and which is secured to the part b of the flangeA by set-screws 2 or by any other suitable means. This tubular air-cham her extends above the flange A, and is closed by a cap, N. The upper end of the discharge-pipe I. has an elbow or spout, I, attached to it, and below this elbow and the said cap N we connect to the tubular air-chamber and also to thediseharge-pipe a cross-head, P, which is preferably yoke-shaped, and from the bend of the'yoke rises a standard, k, to which the pump-handle has its fulcrum. The advantage ofhaving the platform-flange or base-plate A made in the manner described is to afford convenient access to all of the working parts of the pump without removing the entire pump from the well.

By reference to Fig. 6 it will be observed that the actual working parts of the pump have been separated from the parts which are represented by Fig. 5. This is effected by simply removing the fastening-screw z,that

holds the parts a I) together, leaving a part of the pump suspended in the well, and by removing the bolt which holds the rod G to the pump-handle the buckets hfean be removed; or the pump-cylinder Gr may be removed and the buckets repaired. The cheek-valve a may also be secured to the lower part of the pumpcylinder and removed for repairs. to makes a substantial support for that part of the pump which is intended to remain in the well. By having the flange-plate constructed in this manner it saves the necessity of removing the entire pump, as pumps have been heretofore constructed. We thereby also avoid the necessity of descendinginto the well to repair the pump. The said platform -flange or base-plate may be secured to a platform wellcurb by bolts or screws, which serve to hold the two parts of the flange together. It will be also observed that the two tubes or rods B B hold or suspend. the lower part of the pump; also, that the two pipes I J serve to hold down the working part of the pump in proper position. The pipe J serves the purpose of an air-chamber and also as a support for the pumphaudle, and the discharge-tube I also acts as a support for the pump-handle.

The annular flange 0 may or may not be dished toward the central opening.

As the check-Valve 6 opens when the pump is in operation, it will be seen that the water in the cylinder 0 is drawn up into the pumpcylinder, leaving a partial vacuum in the pipes B B, and as soon as the pump is at rest and the cheek-valve closes the hole cl serves as an inlet to allow the water to till the partial vacu um referred to, therefore drawing the water from the discharge-pipe I to prevent freezing.

In pumps now in common use the dischargepipe is provided with a leak-hole to allow the escape ofsurplus water. In such cases the water is returned back into the well, and when a hose is used and a great quantity of water is forced through the pump referred to much water is lost, which necessitates an extra amount of labor to raise the water which is not utilized; and another advantage of the cylinder 0 is that by its being always full of water the pump will always be primed, and in the event of the pump-cylinder losing its water the pump will always be primed. This cylinder 0 also acts as a sand or debris receiver, and is provided with a plug, m, by the removal of which any accumulation can be drawn out. This cylinder O is also provided with a tube, which The flange- By reason of having the flangec inclinedand the upper end of the suction-pipe very small, there will be no lodgment for sand or debris. Hence the valve e will notbe liable to be clogged.

In ordinary pumps the valve-seat is generally large and not provided with means for allowing the debris to escape therefrom and fall below, as we have shown.

The suction-pipe D is' not necessarily provid-' ed with the sand-boXE or the tube F; but we I prefer to use these parts, as above explained, when we use our pump for long suction or driven wells.

Instead of the gate E and its rod, a removable plug or cap may be used; but the advantage of the gate E and its handle is that we may be able to open the sand-box E from the platform or flange, and then by the agitation of the water in the cylinder and the motion given tothe rod or handle E the sand-box can be emptied of any accumulation of.foreigu matter, after which the gate can be shut.

The pipe J may not act as a support for the handle, but it may stop at the platform and an enlarged tubular support be connected to that part of the flange b, as fully explained in the schedule annexed to the patent granted to Roscoe Bean, dated April 4, 1876, and numbered 175,588.

If desired, we may apply to the cylinder (3 a gate and rod or handle similar to what we have shown applied to the sand-box E. The cylind'er 0 not only serves as a charger and debrisreceiver, but it also serves as a coupling for the lower part of the pump-cylinder G, to connect the same with its suction-pipe, and a valve-seat for the check-valve. The air-chamber or the discharge-pipe extends below the platform-flange, and serves, in combination with set-screws or other fastenings applied to the flange A, as the means for holding down the pump-cylinder and insuring close joints between the caps at both ends thereof.

It will be seen from the above description thatl have aframe which is adapted to be suspended into a well and sustained by a flange, and which afl'ords a support for the actual working parts of the pump and its cylinder, which parts are detachable at pleasure from said frame. \Vhen either one or both of the chambers or pipes B are used as an air or vacuum chamber to draw the water from the disehargepipe, such chamber or chambers may open into the pumpcylinder proper below the piston and above the check-valve, this communication being obtained by means of the cylinder 0 and holes at in the flange c. This communication we have shown in the drawings as being through the leak-holedfrom the tube or tubes to the working-cylinder.
