VALVE.

Specification of Letters Patent.

Patented Mar. 4, 1919.

Application filed November 9, 1917. Serial No. 201,110.

To all whom it may concern:

Be it known that I, CARL F. BEACH, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Valves, of which the following is a specification, the principle of the invention being therein explained and the best mode I have contemplated for ap plying that principle, so as to distinguish it from other inventions for a similar purpose.

This invention relates to valves employed in opening and closing conduits for either gaseous or other fluids.

A prominent feature of the present invention is to provide a valve of the class set forth that will, when operated to close the passageway for fluid through its seat, also seal the closure by the pressure of the fluid itself. A further object of the invention is to provide a valve for the purpose whereby wear of the valve and its seat will be reduced to a minimum.

To these ends the present invention consists in the combination and arrangements of parts, as will hereinafter be more fully de scribed, shown in the drawing and defined in the appended claims, it being understood that changes in the form, proportion, size, material and minor details, may be resorted to without departing from or sacrificing any of the advantages of the invention.

In the drawings I have shown my improved valve as applied to a faucet, but to those skilled in the art to which it appertains, it is obvious that the principle involved may with equal advantage be applied tosteam and other conduits.

In the drawings, Figure 1 is a partially broken longitudinal vertical section of a faucet embodying my invention, the valve being represented as moved from its seat.

Fig. 2 is a partially broken longitudinal vertical section of a faucet in modification, embodying my invention, the valve being represented as moved from its seat.

Fig. 3 is another view in broken section of a faucet in longitudinal vertical section, showing a disk valve closed against its seat.

Fig. 4 is a perspective view of the valve connective link.

Like marks of reference refer to corresponding and equivalent parts throughout the different views, in which A represents a faucet nozzle; B, the valve-regulating wheel; C, the gasket nut; and D, the valveregulating screw.

In the embodiment shown in Fig. 1, the faucet is formed in two sections, 1 and 2, the shank or part 1 adapted to be attached to a water pipe or other fixture, having the customary exteriorly screw-threaded end 8, its opposite end being interiorly screw-threaded to receive the exteriorly screw-threaded end of the nozzle portion 2 of the faucet.

An object in forming the faucet in two sections is for the purpose of permitting the faucet to be dismembered at the junction where the valve 4 is located, so that said valve may be readily placed or removed from its connective link 5 near the valve seat 6; the section 1 also may be formed sufliciently large topermit great clearance about the valve antecedent to the opening in the neck of the valve seat.

In the views, the valve operating screw D is received within a correspondingly screw-threaded shank 7 of the faucet, the shank of which terminates in a reduced stem 8, to which the hand operating lever or wheel 13 is affixed. Upon the exterior screw-threaded portion of the shank 7, a gasket nut C is fitted, and between the end of said shank and its nut a gasket or packing ring 9 is placed, in very like manner to faucets generally in use, excepting that in the present instance the valve-operating screw D of the faucet is formed with left handed screw-threads, for the reason that the valve instead of being turned on its axis away from its seat and with the infiowing pressure, is moved longitudinally outward and against the pressure from a hydrant or other force and closed against its seat by a reverse movement of the regulating hand wheel B, so that a person accustomed to the use of faucets or valves generally in use will experience no inconvenience in operating a faucet or valve of the character set forth.

Between the valve 4 and its operating screw D, a transversely apertured hollow link 5 is provided. This link preferably is formed with a reduced screw-threaded stem 11, over which the valve 4 is fitted, the latter being held on said stem by means of a washer 12, against which a small nut 13 is run on to said shank. This link is cylindrical in form and the end to which the valve 4 is attached is provided with a series of longitudinally-made grooves 14 so that an abundance of fluid may be admitted. after the valve is moved from its seat, the opposite end of the link having a central bore 15 through which a reduced stem 16 of the operating screw D, as shown in Fig. 3, may engage for holding and operating the valve.

In Fig. 3 I have shown a: valve-operating link fitted to the operating screw D from a stem of the latter, a small washer 17 being placed within the aperture of the link over said stem and secured by means of a small pin or screw 18.

In Figs. 1 and 2 a button-headed screw 19 is used in lieu of the stem aforesaid. The screw itself being screw-threaded into the end of the alx' e-operatin'g screw D.

In Fig. 3 I have shown the faucet formed of one general casting having a valve seat 6' opening near and toward its screwthreaded extremity 3, and in this view I have also shown a valve 4 of the .disk character, which may comprise indurated fiber, metal, leather, rubber or other mate rial, according to the use for which it is required.

Where cold water and non-corrosive fluids are to be controlled by a fixture equipped with a valve of this class, a preferred type of valve is shown in Figs. 1 and 2, in which the valve 4 is of firm rubber having its seating end nominally oval or round that itmay readily fit within the tapering valve seat. In the embodiment in Fig. 2 a faucet is shown with avertically-disposed shank 7, through which the valve is operated. In this instance the valve seat 6 is disposed horizontally between the intake end 3 and 40' the nozzle A, an opening being provided in alinement with the valve 4 within the under side of the faucet and fitted with a screw-threaded cap or cover 20 forming a trap. By the provision of the opening and its cover, the valve may be introduced or removed as occasion may necessitate.

It is important that the link 5 may have a light longitudinal movement on its bearing, as on the stem 16 or screw 19, where it connects with the va1ve=operating screw D, for the reason that when the valve is nominally drawn against its seat, as shown in Fig.- 3-, there may be a clearance as aforesaid, soas to preclude a predetermined and fixed seating of the valve, which seating might be defective through wear of'the operating screw where no such provision is made to' counteract such occurrence, and especially owing to the fact that when nor- -rnal1y closed by handa fluid pressure is against the valve tending to' more snugly seat the same.- Inasmuch as the link 5 and its valve 4 donot rotate in either opening or closing said valve, with respect to its seat-,1 no great wear oneither the valve or in connection with the drawings, a more extended explanation of the objects and-ad vantages of my invention is believed to be unnecessary.

Having, therefore, described my inven-' tion, what I claim as new and desire to secure by Letters Patent, is

1. In a valve, the combination with a conduit having an apertured packing nut screwthreaded over the end thereof, and a gasket interposed between said nut and said: 0011- duit, a valve-operating screw screw-threaded into the end of said conduit and having areduced operating shank extending through said gasket and packing nut, of a stem extending from the opposite end of said" valveoperatmg screw, a hollow cylindrical link having a longitudinal-ly-disposed transverse aperture therethroughswiveled at one end to said stem, the opposite .end of said link having longitudinally-disposed grooves extending from the end to the aperture through said link, a valve aflix'ed to the end of said link having said grooves, and a concentric valve seat within said conduit about said link in close proximity to said valve whereby by the turning of said'operating screw said valve may be moved to and from saidv valve seat.
