VALVE.

SPECIFICATION forming part of Letters Patent N 0. 663,593, dated December 11, 1900.

Application filed March 17, 1900. Serial No. 9,071. (No model.)

To ctZZ whom, it ntcty concern:

Be it known that we, WILLIAM W. WILSON, of Holyoke, in the county of Hampden, and WILLIAM A. STEVENSON and CHARLES E. TORRANOE, of Northampton, in the county of Hampshire, State of Massachusetts, citizens of the United States, have invented a certain new and useful Improvement in Valves, of which the following is a description, reference being had to the accompanying drawings, in which- Figure l is a view of a valve embodying said improvement partly in elevation and partly in central vertical section. Fig. 2 is an enlarged sectional detail. Fig. Sis a section on the line 3 3 of Fig. 1, and Fig. 4 is a section on the line 4 4 of Fig. 1.

The object of the improvement is the production of a two-way valve having features of novelty and advantage, in which either or both ways may be closed at pleasure.

In the accompanying drawings the letter a denotes a hollow valve-body having an inletorifice b. The letter 0 denotes an outlet-orifice of said hollow valve-body upon one side of the inlet-orifice, and the letter d denotes a similar outlet-orifice upon the other side of the said inlet-orifice. The letter 6 denotes a valve seat appurtenant to the first mentioned of these outlet-orifices, and the letter f denotes a similar valve-seat appurtenant to the other of said outlet-orifices.

The letter g denotes a longitudinally-movable main valve-rod. It is moved longitudinally by rotating the wheel-nut h, which takes upon a threaded part of the main valve-rod and which is held to place by the split flange or collar 2'.

The letters It and Z denote two valve-closers which are carried through the medium of the main valve-rod, and by the longitudinal movement of that valve-rod either of the outletorifices can be closed. While the valve Z is carried back and forth through the medium of the main valve-rod g, in ordinary circumstances it is borne immediately by a subsidiary valve-rod m, carried within the main valve-rod, which is made hollow for that purpose. The subsidiary valve-rod and its valve can be moved longitudinally independently of the main valve-rod, which movement is accomplished by the rotation of the nut 'n by means of the hand-Wheel 0 upon a threaded portion ofthe subsidiary valve-rod. This nut n is a split nut fastened, as by screws, to the hand-wheel o and held to its place on the main valve-rod by its embrace of the flange g, which is a part of the main valve-rod. It will be understood that while the nut n is longitudinally stationary upon the main valve-rod it is yet free to rotate thereon by manipulation of the hand-wheel 0, and that such rotation of the nut causes the subsidiary valverod and the valve-closer Z to move longitudinally independently of any motion of the main valve-rod. The main valve-rod is held from rotation by the feather g traveling in a suitable spline within the valve-body. The subsidiary valve-rod is held from rotation independently of the main valve-rod by the pin m, carried in the main valve-rod and projecting into a spline in the subsidiary valve-rod.

The letter 1) denotes a stuffing-box for the main valve-rod.

In the ordinary working of this valve the valve-closer Z remains against the lower end of the main valve-rod and by the manipulation of the wheel-nut h in one direction or the other either valve-closer is made to close its valve-orifice, as may be desired; but when it is desired to close both of the valve-orifices at the same time the valve-closer It is first brought to its seat by the manipulation of the wheel-nut h and then the valve-closer Z is brought to its seat by the manipulation of the hand-wheel 0.

We claim as our improvement- 1. In combination; the hollow valve-body provided with an inlet-orifice and an outletorifice on opposite sides of said inlet-orifice; a valve-seat appurtenant to each of said outlet-orifices; a longitudinally-movable main valve-rod; the valve-closers positively carried through the medium of said main valverod and adapted to simultaneously and alternately open and close the valve-orifices through the movement of said valve-rod; and means for positively moving one of said valveclosers to and from its valve-seat independently of the movement of said main valverod; all substantially as described and for the purposes set forth.

2. In combination; the hollow valve-body provided with an inlet-orifice and an outletorifice on opposite sides of said inlet-orifice; a valve-seat appurtenant to each of said out- 1et-orifices; the hollow longitudinallymovable inain valve-rod; a valve-closer carried by said main valve-rod and adapted to open and close one of the valve-orifices; the subsidiary valve-rod carried by and longitudinally movable in the main valve-rod; the valve-closer carried by said subsidiary valverod; and independent mechanisms for moving the main and subsidiary valve-rods inde pendently, all substantially as described and for the purposes set forth.

3. In combination; the valve-body having two outlet-orifices and an inlet-orifice between them, with a valve-seat appurtenantto each outlet; the hollow longitudinally-movable main valve-rod carrying a valve-closer for one seat; the subsidiary valve-rod extending through the main rod and carrying a valvecloser for the other seat, each rod being exteriorly threaded; two handwheels having nuts engaging the respective threads; a swivel connection between one nut and the main valve-rod, and between the other nut and the valve-body; and means for preventing rotation of the two rods, as and for the purpose set forth.
