VALVE.
Specification of Letters Patent.
Patented Oct. 10, 1905.
Application filed November 21, 1904. Serial No. 233,724.
To (11/ whom it may concern:
Be it known that 1, JOHN J. Bowns, Jr., a citizen of the United States, residing at Pensacola, in the county of Escambia and State of Florida, have invented new and useful Improvements in Valves, of which the following is a specification.
My invention relates to valves; and its primary object is to provide a new and useful device of this character which can be easily and cheaply manufactured, which is durableand efficient, and which is composed of few parts so arranged and constructed as not to be liable to become broken or inoperative.
A further object of the invention is to provide a novel packing for the valve of approximately U shape in cross-section, providing wings or members normally retained sepa rated from each other under the inherent tendency of the material from which the packing is constructed to effectually prevent leakage of the valve.
With the above and other objects in view the invention consists in the construction and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawing, wherein the figure is a sectional view of a valve constructed in accordance with my invention.
Referring to the drawing by reference-numerals, l designates a valve-casing having inlet and outlet openings 2 and 3, respectively. The interior of the casing 1 is provided with verticallyarranged walls or partitions 1, spaced apart and connected by means of a horiZontally-disposed wall or partition 5, the latter being provided with an opening 6 to provide communication between the inlet and outlet openings 2 and 3. A cylindrical valveseat 7 rises vertically from the partition 5 about the opening 6 and has its upper edge inclined, as shown at 8. The cylinder has removably secured thereto a cap 9, which is provided with a centrally-arranged screwthreaded opening 10 and a depending sleeve 10, having a tapered seat 10. The outer upper edge of said cap is provided with screwthreads 12, adapted to be engaged by an internally-screw-threaded flange 13 of a capnut 1;, said cap-nut being provided with a centrally-disposed opening alining with the opening in the cap 9 and with the valve-seat.
15 designates a valve of a diameter equal to the interior diameter of the valve-seat T and of a thickness a little less than the height of said valve-seat. The valve is provided in its upper face with a recess adapted for the reception of the enlarged head 16 of a valvestem 17, said valve being swiveled to the valve-stem by means of a nut 18, which has its upper portion tapered, as at 18", to correspond to the seat 10. The valve-stem is provided with a screw-threaded portion 19, adapted to be received by the screw-threaded opening 10, and has its upper end projecting above the cap-nut 14c and upon which is mounted an operating-wheel 20. It is apparent that by turning the valve-stem in one direction or the other the valve is either seated or unseated. The valve 15 has its working face provided with annular recesses 22, interposed one above the other, as fully disclosed in the drawing, and the upper edge of said face is inclined, as disclosed at 23, adapted to engage the inclined portion 8 of the valve-seat.
24E designates a packing U-shaped in crosssection and adapted to be received by the recesses 22. In view of the construction of the packings 2* members 25 are provided, and said packings are adapted to be constructed from rubber or other resilient material, said members being normally retained separated through the inherent tendency of the material. This tendency of the members to separate causes them to be brought into engagement with the inner opposing walls of the recesses 22 and valve-seat 7 whereby all liability of leakage occurring after the valve has been seated is obviated. A similar packing 26 is situated in a recess 27 in the upper end of the cap 9 about the valve-stem 17. \Vhen it is desired to remove the packings 26 to apply a new packing, the valve-stem is turned so as to bring the tapered portion 18 of the nut 18 into engagement with the seat 10", thereby preventing the escape of fluid through the cap and rendering the application of a new packing easy.
From the foregoing description, taken in connection with the accompanying drawing, the construction and mode of operation of the invention will be understood without a further extended description.
Changes in the form, proportions, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.
Having thus fully described the invention, what is claimed as new is 1. A valve comprising a casing having a port therein, a cylindrical valve-seat rising from said port and having a beveled upper end, a valve adapted to fit within said seat and provided with a plurality of annular grooves, the upper flange-wall of the upper groove being beveled to engage the said beveled upper end of the valve-seat, said valve also being formed in its top with a threaded socket, packingrings arranged in said grooves, said rings having their contiguous edges formed with V- grooves, a cap secured to the casing and provided with a valve-seat, a valve-stem working in the cap and having a head seated in said socket, and a nut engaging said threaded socket and formed with an opening for the passage of the valve-stem, whereby the headed end of the valve-stem is swiveled to the valve, said nut being formed with a valve portion to close against the seat of the cap when the said main valve is fully opened, substantially as described.
In testimony whereof I afiiX my signature in presence of two witnesses.
