PUMP.

No. 320,737. Patented June 23,1885.

NITED STATES PATENT OFFICE.

JOHN WVOOK, OF CANTON, OHIO, ASSIGNOR OF ONE-HALF TO JOHN C. SKELTON AND ALBERT HOEFFER, BOTH OF SAME PLACE.

PUMP.

SPECIFICATION forming part of Letters Patent No. 320,737, dated June 23, 1885. Application filed July 26, 1884. (No moan.)

To all whom it may concern:

Be it known that 1, JOHN NVOCK, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Pumps and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon, in which- Figure 1 is a side elevation. Fig. 2is a side elevation showing pump in section. Fig. 3 is an end view of the lower portion or bottom of the large tube or pipe. Fig. 4 is a bottom view of the inside tube, and Fig. 5 is a transverse section of the pump.

The present invention has relation to the general improvement in pumps; and it consists in the construction and combination hereinafter particularly described and claimed.

Similar letters of reference indicate corresponding parts in the drawings.

In the accompanying drawings, A represents the large tube or body of the pump proper, which is substantially of the form shown in the drawings, the bottom or lower end of which is provided with the openings a and the valve B. Said valve may be of the form shown in the drawings, or any other desired form. A close union will be made between the top of the tube A and the hollow piston D, so as to make the connection at such point perfectly water-tight by means of a cap, 0, fitted about the piston D, so that the latter may slide therein, and formed of a circular band of larger diameter than the tube A with lugs c on its inside and having a converging top within which is any suitable packing, 0 0 as shown. The lugs c of the cap will engage or interlock with the beveled or inclined ilangcs 0, formed on a collar, 0, secured to the upper end of tube A. By passing the lugs a between the ends of flanges c and then turning the cap 0, the latter will be drawn down tight upon the tube A and the packing composed by the converging top of the cap, so that a close union. will be effected between the tube and hollow piston and water prevented from escaping.

\Vithin the tube A is located the hollow piston D, which is substantially of the form shownin the drawings, the bottom or lower end of which is provided with the valve d,

which may be of the form shown in the drawk ings, or of any other desired form. The bottom or lower'end of this hollow piston is provided with the packing E, which is to fill the tube A, as seen in Fig. 2. Just above the packing E is located the vent F, which permits the water to pass between the hollow piston and tube A, so as to flow out through the spout A Any desired number of these vents may be used. This hollow piston is formed airtight at its top, so as to form an airchamber within said hollow piston, thereby causing the pump proper to throw acontinuous stream after it has been properly filled.

It will be seen that by an upward movement of the hollow piston the tube A will be filled by means of the suction caused by the packing E, and that by a downward movement of said hollow piston it will befilled from the water in the tube A, when an upward movement will again fill the tube A and also carry up the water within the hollow piston D, when a downward movement will fill the tube A above the packing E, thereby causing the pump proper to throw a continuous stream. It will also be seen that by my peculiar arrangement I am enabled to form a valve-seat, an air-chamber, and also the operating-rod in a single piece or tube.

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

In a liitpump, the combination of the pump barrel A, having at its upper end the inclined flanges c, the hollow valved plunger D, work ing within barrel A, the cap 0, fitted about plunger D and formed of a band larger in diameter than tube A, and having lugs c on its inside, and a top converging from it to the plunger D and a packing in the converging top, as shown, for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in presence of two witnesses.
