CHECK-VALVE FOR PUMPS.
SPECIFICATION forming part of Letters Patent No. 339,584, dated April 6, 1886. Application filed September 5, 1885. Serial No. 176,247. (No model.)
To all whom it may concern:
Be it known that I, HENRY DWIGHT Beer, of Reading, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Check-Valves for Pumps, which improvement is fully set forth in the following specification and accompanying drawings, in which- Fignre 1 is a vertical sectional view of a pump stock equipped with my improved check-valve and valve-guide for rods or stems, and Fig. 2 is a modified view of same detached from the pump tube or stock.
In the manufacture of pumps I find that it is difficult to construct a check-valve for the ordinary wooden valve which is both durable, easily applied, andaccessible in case of damage. I further find that in deep wells a single check-valve at the lower end of the pumpstock is compelled to hold too great a column of water, hence the valve is readily injured or thrown out of repair. To obviate this, I provide for one or more check-valves on the same stem, as will hereinafter be shown. It is also obvious that where the ordinary hell or cup shaped valve is used, either on the check or on the pumprod or pistoirrod, that the leather comprising the valve soon becomes soaked and thoroughly softened; hence, where one side of the valve is thicker than the other, or there is a greater pressure from any cause on one side than the other, the valve is pressed out of shape or collapses. I n order, therefore, to prevent this and keep the check-valve or the piston-rod in the center of the pump-stock, I provide the stem or rod with wings or guides, all of which will now be set forth in detail.
In the accompanying drawings, A represents the pump tube, pipe, or stock, provided at its lower end with a series of holes or apertures, B.
C represents the piston or pump rod, having at its lower end the common hell or cup valve 1), or any other form of valve that may be desired. hen, however, the bell or cup valve, as shown, is used, I provide the rod 0 above the valve with two wings or guide pieces, E, placed through the rod and at right angles to each other, the wings extending out from the rod equidistant on all sides, so as to keep the rod O in the middle of the tube at all times.
F represents the check valve rod or stem having at its lower end a head, G, permanently attached, which serves as a plug to close the lower end of the tube A. The stem F may be of any length, so as to carry thereon one or more cup or bellvalves, H. In casethe well is deep, I make the check-valve stem long and extend it up into the tube and place there on two or more valves, H, so that the water in being drawn up the tube will be held by the successive valves. F is provided with wings or guides E, so as to keep the stem in the center of the tube.
In like manner the stem It is obvious that the GllGCkWfliVG, as here- I in constructed, can be readily applied to a pump or detached when necessary.
Having described my invention, what I claim as new is- 1. In a. pump-stock, the valve-stem 0, provided with cup-valve D, and wings or guidepieces E, at right angle to the stem, substantially as and for the purposes described.
2. A check-valve composed of a stem having on its lower end a head which serves as a plug for the lower end of the pump-tube, and on said stem one or more cup-valves and guides or arms projecting from said stem, in combination with the tube or pump stock, substan tially as herein set forth.
3. The combination of the tube A with the stem F, having the head or plug G, the valves H H, and the guides or wings E, substantially as herein set forth and described.
In testimony that I claim the foregoing I have hereunto set my hand, this 27th day of August, 1885, in the presence of witnesses.
HENRY DWIGHT ROOT.
