' IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 219,529, dated September 9, 1879 application filed To all whom it may concern:

Be it known that I, JOHN F. RYAN, of Maysville,in the county of Mason and State of Kentucky, have invented certain new and usefulImprovements in Pumps; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 is a partial vertical sectional view taken through the line 4 4 in Fig. 4. .Fig. 2is a vertical view, partially in section, through the line 2 2 in Fig. 4. Fig. 3 is a partial vertical sectional View through line 3 8 in Fig. 4, and Fig. dis a sectional plan view taken through line 1 '1 in Fig. 1.

The nature of my invention consists in the construction and arrangement of a pump, as will be hereinafter more fully set forth.

The annexed drawings, to which reference is made, fully illustrate my invention.

A represents the pump-cylinder, closed at the bottom, and provided at the top with a cover, B, which is suitably packed and fastened with bolts or otherwise, as desired.

In the cover B is fastened the dischargepipe 0, on which is a guide, D, for the passage of the plunger-rod a,the upper end of said rod being connected to one end of the handle E. This handle is pivoted to a collar or bearing, F, which is secured to the discharge-pipe.

G is the piston or plunger working in the cylinder A and attached to the lower end of the rod to. This plunger is preferably to be made in double-cup form, and capable of expansion to compensate for wear.

On one side of the cylinder-A is the suctionpipe I, open at the lower end, and has its upper end provided with a ballvalve, b.

The suction-pipe opens above the valve 1) into the cylinder, and below the valve it opens into a passage, 61, which communicates with a tube, 1, said passage dhaving' a ball-valve, b, in its upper end. The lower end of the tube I opens into the cylinder A at the bottom.

On the opposite side of the cylinder are outlet-passages J J, opening, respectively, from the top and bottom of the cylinder, and provided at the top with check ball-valves 1th.

The lower end of the discharge-pipe O is direct] y over the space between the valves h h, so that the water coming from either outletpassage will pass out through said dischargepipe.

. It will be understood that the pump-cover B is extended so as to cover and close the various side passages, as shown and described.

All the four valves, it will be noticed, are in my pump placed at the upper end of the cylinder, so that by removing the cover all the valves and the plunger are exposed to view, and if anything is out of order it can be seen at a glance and such repairs made as are nec essary without removing anything else.

The ball-valves are to be made of rubber, formed over iron cores or centers to give them sufficient weight to make them sea-t promptly.

' The pump is drained, to keep from freezing in winter, by means of a plug-cock, L, inserted in the pipe 0 about four feet below the cistern or well cover, and a rod, f, running up from said plug-cock to or above the pump-handle, the upper end of said rod forming a handle for operating the same.

One of the main advantages of my invention is that by the arrangement of valves and ports as described the pump will never lose its priming, but is always ready to start at the first stroke.

At the downward stroke of the piston G the water below the same is forced up through the tube J, lifting the valve h, and the waterpasses out through the discharge-pipe, while at the same time the suction draws the water up through the pipe I, lifting the valve 11,

and causing it to fill the cylinder above the piston.

At the upward stroke of the piston the water above it is forced out at J, lifting the valve h, and then out through the discharge-pipe. This action seats the valve 1), and the suction draws the Water from the well through I and In testimony that I claim the above I have ddown the tube I and into the bottom of the hereunto subscribed my name in thepreseuce cylinder. of two Witnesses.

I claim- The combination of the suction-tubes 1 I, JOHNFRANKLIN RYAN.
