class of cocks which are provided with re- 1 ciprocating valves.
An object of this invention is the provision of a stop cock of this character in which the valve thereof will not be jarred from its seat owing to vibrations, the valve being maintained tightly against its seat by the tension of its spring and being readily removable from its seat against the tension of the spring.
A further object of this invention is the provision of a stop cock in which is mounted a spring pressed reciprocating valve, means. being provided to maintain the valve in open position against the tension of its spring.
With these and other objects in view, my invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,
Figure 1 is a vertical sectional view of my improved stop cock. Fig. 2 is a fragmentary elevational view showing the valve stem in its innermost position. Fig. 3 is a fragmentary elevational view showing the valve stem in its outermost position. Fig. 4 is a sectional view on the line 44 of Fig. 1. Fig. 5 is a section taken on the line 55 of fieferring'more particularly to the drawing, the numeral 1 designates the body of the valve which is provided with a longitudinal bore 2 extending entirely therethrough, the body being threaded at its inner end for engagement in an opening in a tank or other suitable connection (not shown).'
The body is formed in one side thereof with a transverse opening 3 which communicates at its inner end with the bore 2, the opening being reduced adjacent its inner end to form a shoulder 4. The outer end of the opening 3 is threaded, and threadably mounted in the threaded portion of the opening 3 is a tubular guide sleeve 5, the shoulder 4 being adapted to limit the inward movement of the sleeve within the body of the cook. The outer end of the guide member 5 is closed, the closed end thereof being provided with a central opening 6, and slidably mounted in the guide member is a -valve -which has a valve stem 8 projecting outwardly therefrom, the outer end of the valve stem belng slidably disposed through the opening 6 in the outer wall of the guide member, and is formed with a shoulder 9 intermediate of its ends which is adapted for engagement with the end wall of the guide member to limit the outward move- Specification of Letters Patent. Patented Dec, 22, 1914.
opening 3 in the body is a valve seat 10 with which the inner end of the valve 7 is adapted to engage to close the bore 2 in the body. A chamber 11 is formed in the inner end of the valve, the chamber being adapted to of the valve, the valve may be quickly closed against the pressure of the liquid between the same and its valve seat as the liquid disposed between the inner end of the valve and its seat as the valve is closed, may pass directly into the chamber so that the valve may-quickly engage the seat without being' retarded by the liquid as it otherwise would be in case the inner end of the valve were solid. Formed in the valve '7 is a peripheral groove 13 in which a packing ring 14 is mounted to provide a tight joint between the valve and the inner wall of the guide member 5.-
A coiled expansion spring 15 is mounted. in the tubular member 5 outwardly of the valve, the outer end of the spring engaging the end wall of the guide member and the inner end of thespring engaging the outer end of the valve to normally force the same inwardly to engage its seat 10. Surrounding the outer end of the guide member 5 is a sleeve'16, the outer end .of which is provided with an inwardly extending flange 17 the inner edge of the flange engaging in an annular groove 18 in the stem 8 adjacent its outer extremity, whereby the sleeve 16 is fastened to the stem to move outwardly and inwardly with the same. A finger ring 19 is loosely connected to the projecting extremity of the stem 8 whereby the same may be readily moved outwardly to \remove the valve from engagement with its valve seat 10. The tubular guide member 5' is formed with an outwardly punched bead or projection 20, and the sleeve 16 is formed with a longitudinal groove 21 which extends from a point intermediate of the ends of the sleeve to the inner end thereof, the groove being formed by crimping a portion of the sleeve outwardly and is adapted for slidable engagement with the bead when the same is in its innermost position,
In the practical use of my device, the valve 7 is normally inits innermost position against its seat 10 to cut off the flow of liquid through the cock; and when it is desired to allow the liquid to pass through the cock, the finger piece 19 is grasped and pulled outwardly to remove the valve from engagement with its seat against the tension of the spring 15. Upon release of the finger piece 19, the valve will be immediately closed by the expansion of the spring 15 and the valve is held in this position until the finger piece. 19 is again pulled outwardly. If it is desired to hold the valve "in openposition, the valve stem is moved outwardly until the shoulder 9 thereof engages the outer wall of the guide member 5, and in this position, the inner edge of the sleeve 16 is disposed outwardly of the bead 20 on the member 5, so that upon rotation ,of the ring 19, the sleeve is also rotated by reason of its rigid connection to the stem to move the crimped portion 21 of the sleeve out of longitudinal alinement with the bead, whereby upon release of the ring 19, the inner edge of the sleeve engages the bead to hold the stem in its outermost position and the valve 7 in spaced relation from its seat. When it is desired to close the valve it is only necessary to rotate the ring 19 until the slot is again in'alinement with the head 20 so that uponrelease of the finger piece 19, the valve is forced inwardly upon its seat by the spring 15.
Having thus fully described my invention, what I desire to secure and claim by Letters Patent is :-v
1. A stop cock comprising a body having a longitudinal bore extending therethrough, said body having a transverse threaded opening in one side thereof communicating with said bore, a tubular guide member threadably mounted in said opening, said body having a valve seat formed therein at 'a point diametrically opposite the transverse opening, a spring pressed valve slidably mounted in said guide member for engagement with the valve seat, a valve stem carried by the valve and projecting through said guide member, an outwardly projecting bead formed on said guide member, a sleeve carried by the projecting portion of the stem and adapted to surround the outer end of the guide member, said sleeve having an outwardly crimped longitudinal groove formed therein which extends from a point intermediate of the ends of the sleeve to the inner edge thereof, saidbead being disposed within said groove when the valve is in closed position, and the sleeve being adapted for rotation to dispose the inner edge of the sleeve against the bead when the valve is in open position.
2. A stop cock comprising a body having a longitudinal bore extending therethrough, said body having an opening in one side thereof communicating with said bore, the body having a valveseat formed therein at a point diametrically opposite the transverse opening, a tubular guide member mounted in said opening, a spring pressed valve slidably mounted in said guide member for engagement against the seat, a valve stem carried by said valve and projecting through said guide member, the projecting portion of said valve stem having an annular groove formed therein, a sleeve surrounding said guide member and having an inwardly extending flange formed on its outer end, the inner edge of said flange being engaged in said annular groove, whereby upon movement of the valve stem the sleeve is carried therewith, and means formed on said guide member for engagement with the inner edge of said sleeve to hold the valve in open position against the action of its spring.
In testimony whereof I hereunto afix my signature in the presence of two witnesses.
