VALVE.
SPECIFICATION forming part of Letters Patent No. 767,228, dated August 9, 1904. Application filed October 30, 1903. Serial No. 179,142. (No model.)
To @Z3 whom, it 711/01/ concern:
Be it known that I, WILLIAM T. HARRISON, a citizen of the United States, and a resident of Savannah, in the county of Chatham and State of Georgia, have invented a new and Improved Valve, of which the following is a full, clear, and exact description.
This invention relates to improvements in valves for controlling the outow of water from railroad-tanks, an object being' to provide a valve so constructed that it may be readily removed for repairs without first running the water out of the tank, and, further, to provide a simple means for preventing the rattling or .jumping of the valve.
I will describe a valve embodying' my invention and then point out the novel features in the appended claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate correspondingparts in both the figures.
Figure 1 is a sectional elevation showing a valve embodying my invention as connected to a tank, and Fig. 2 is a sectional view of the valve drawn on a larger scale.
Referring' to the drawings,'1 designates a .water-tank through the bottom of which a tubular valve-casing' 2 extends and communi- Cates with the discharge-pipe 3. The inner end of the casing 2 forms a valve-scat for the plate-valve 4, having' a packing or ring 5, of rubber, secured to its under side for engaging with the valve-seat. Extended upward from the valve 4 is a tube 6, having a screw-cap 7, and provided near its upper end with air-vents 8. Arranged to move in the valve-casing 2 and to engage with the valve-seat 9 therein is a stopper-valve 10. This stopper-valve has a tubular extension 11, provided with ports 12, for the outiiow of water, as will be hereinafter described. The valve 10 has air-vents 13, which will prevent the escape of air when the valve 10 is in its uppermost position. From the stopper-valve l() an operating-rod 14 extends upward through the tube 6 and through an opening in the cap 7, and at its upper end it is removably connected with a lever 15, extended through the tank and connecting with a draw-rod 16.
On the screw-threaded portion of the rod 14 is a nut 17, which by being forced downward on the cap 7 will draw the stopper-valve 10 closely against the packing-ring 5, holding the same in position.
Seated in an annular channel formed in the upper portion of the valve-seat for the valve 4 is a packing-ring 18, of any suitable noncorrodible material.
In the operation, while filling the tank 1 by means of a pump or other device, the air in the tank will be forced out through the openings 8 and through the air-vents 13 into the outlet-pipe 3, the valve 10 being at this time off its seat, and thus the valve will be prevented from jumping or rattling, as is usually the case when outrushing airis forced against it. These openings and vents will also provide for the overflow when the tank is suflciently filled.l To discharge water from the tank, the two valves are to be drawn upward until the ports l2 reach a point above the valvecasing 2. rThen of course the waterpasses out through said ports 12. The tubular extension of the stopper-valve not only provides a means for this outflow of water, but it serves as a guide for centering and seating the valves. IV hen it is desired to remove the valve 4 for renewing' the packing 5 or for other repairs. the rod 14 is to be released from the lever 15 and the nut 17 removed. Then the tube 6, with the valve 4 and packing, may be lifted off, and at this time the stopper-valve will be moved downwardto engage the valve-seat 9, thus preventing any outflow of water. After making the repairs the valve 4 is to be replaced and the valve l0 drawn against the packing thereof by means of the nut 17.
Having thus described my'invention, I claim as new and desire to secure by Letters Patent- 1. A valve for a water-tank, comprising a valve-casing, a valve for engaging against the inner end thereof, a tube extended upward from said valve and having air-ports at its upper end; a stopper-valve movable in the casing and having outlet-ports and vents above the ports, a rod extended from said stopper-valve through said tube, and a nuton said rod for holding the stopper-valve against the Yfirstnamed valve.
IOO
2. A valve for a Water-tank, comprising' a valve-casing, a plate-valve for engaging against the inner end thereof, a packing-ring arranged in said plate-valve, a tube extended upward from the plate-valve and having airopenings near its upper end, a cap on the upper end of said tube, a stopper-valve operating in the valve-easing and having a tubular eX- tension provided with ports, the said stoppervalve also being provided with vents, a rod extended from said Stopper-valve through the said tubo and cap, and a nut engaging' with a screw-threaded portion of said rod above the cap.
In testimony whereof lhave Signed my naine I 5 to this specification in the presence of two subscribing witnesses.
