AUTOMATIC CHECK-VALVE.
Specification of Letters Patent.
Patented Sept. 19, 1911.
Application filed July 18, 1910. Serial No. 572,548.
To all whom it may concern:
Be it known that I, JAMES E. STAPLES, a citizen of the United States, residing at Beloit, in the county of Rock and State of lVisconsin have invented certain new and useful Improvements in Automatic Check- Valves, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to automatic valves and the pricipal object of the same is to provide a valve which will do away with the danger of leakage.
Other objects will appear in the course of the following specification.
This invention is illustrated in the accompanying drawings wherein- Figure 1 is a longitudinal sectional View of the improved valve showing the same in an operative position. Fig. 2 is a view of the valve seat. Fig. 3 is a view looking through the end of the body of the valve in the direction of the arrow. Fig. 1 is a view of the body of the valve showing particularly the threaded connection for the cap.
Referring to the said drawings by numerals 1 indicates the body of the valve which may be made of any desired metal such as for instance iron, steel, copper, or brass, one end of the body having an extension 2 which is provided with a series of parallel faces better shown in Fig. 3. The face will be engaged by a wrench. The portion 2 has a centrally located longitudinally extending threaded opening 2, adapted to be screwed upon a source of supply. The forward end of the body is provided with a plurality of openings 3 forming a central valve seat 1 which is connected to the main body by the webs 5. It will, of course, be understood that any desired number of openings may be provided. The seat 4 is provided with a longitudinally extending threaded opening which extends a portion of its depth. The
wall of the body is reduced and has an externally threaded portion indicated by the numeral 6 and terminates in an abutment wall 7. A valve 8 is placed upon the valve seat and is of sufficient size to completely cover the openings 3, and can be made of any material as for instance of a piece of rubber, wood, paper or fiber or any desired metal. A plate 9 of the same size as the valve is placed thereon and the valve and plate are provided with an opening adapted to register with the threaded opening in the seat. The valve and plate are held in place by means of a coil spring 10 which may be adjusted by means of the stem 11 which is provided at one end with a threaded portion 11 adapted to enter the threaded opening in the portion 4. The valve seat 1 is provided with a rounded projection 4, which protects the threaded end 11 against the destructive action of the fluid, and serves to spread the fluid, to promote its flow through the openings in the valve seat. The outer end of the stem 11 is provided with an enlarged tapered portion 12 and terminates in an abutment head 13, which is provided with a plurality of parallel faces adapted to be en gaged by a wrench to adjust the stem. When it is desired to increase or diminish the pressure upon the valve the stem is turned in the desired direction and the pressure increased. or decreased upon the coil spring 10. A cap 1 1 is provided with an internal thread 15 adapted to fit the threaded portion 6 of the body 1 and the wall of said threaded portion is of the same thickness as the abutment wall 7 so that when the cap is placed upon the body the valve will have a flush surface. The other end of the cap has an extension 16 similar to the portion 2 of the body and is provided with a threaded opening 17 adapted for engagement with a discharge pipe.
This valve is adapted to be used in any kind of a device where the supply of material passing through the same has an alternating pressure, such for instance as a reciprocating pump. It can be used for either liquid or gaseous fluid. When the device is applied upon a windmill, the upward stroke of the piston causes the water to come with considerable force and opens the valve to allow the water to pass through. Upon the return stroke the pressure is decreased and the spring 10 closes the valve and thus prevents any danger of the water in the discharge pipe from returning. If a gaseous fluid is used there is no danger of it escaping through the opening that the adjusting stem is threaded into as the end is closed as illustrated in Fig. 1. It will also be noted that the gas could not escape where the body and cap are connected as there is a thick wall between the same and the interior of the body.
Having thus described my invention, what I claim as new and desire to protect by Letters Patent is v In a valve, a valve body formed in two sections, one of said sections forming an inlet and the other section forming an outlet, the inlet section being formed with a concentric shoulder and the inner end of the outlet section being threaded to said shoulder, a valve seat formed on said inlet section and provided with a central rounded portion projecting toward the inlet thereof to form a fluid spreader, said valve seat being formed with openings located around the spreader, a stem threaded into the rounded portion of the Valve seat, a circular valve movable on said stem and seat, a head secured to said stem, and a spring bearing at one end against the head and at the other against the valve.
In testimony whereof I hereunto afliX my signature in presence of two witnesses.
