WASTE-VALVE FOR WATER AND STEAM PIPING SYSTEMS.

SPECIFICATION forming part of Letters Patent No. 586,779, dated July 20, 1897. Application filed August 18, 1896. Serial No. 603,127. (No model.)

T0 (all wiz/0m it may concern.-

Be it known that we, HORACE F `-iLK NEU- MEYER, residingl at Macungie, in the county of Lehigh and State of Pennsylvania, and JONAS FRANCIS YOUNG, residing at Niagara Falls, in the county of Niagara and State of New York, citizens of the United States, have invented a new and useful Taste-Valve for Water and Steam Piping' Systems, of which the following is a specification.

This invention relates to waste-valves for use in connection with water and steam piping systems; and it has for its object to provide a new and useful valve of this character especially well adapted for use in connection with hydrants, whereby the service pipe or pipes can be automatically drained of surplus or standing` water therein, which is of considerable importance in cold weather to prevent freezing and the consequent annoyances.

lVith these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

ln the drawings, Figure l is a vertical longitudinal sectional view of a waste-valve constructed in accordance with this invention and shown in its normal position for draining surplus water in a hydrant or piping thereabove. Fig. 2 is a similar view on the line 2 2 of Fig. l, showing the valve closed to permit a free passage of liquid therethrough without waste or escape thereof. Fig. 3 is a similar view to Fig. 2, showing a modified form of valve without the use of springs. Fig. l is a sectional view of the valve, showing an arrangement of the parts to adapt the valve for use in connection with steam-pipes for draining from such pipes the water of condensation after live steam is cut ott.

Referring to the accompanying drawings,

the numeral l designates a valve-casin g preferably made in sections and comprising the separate casing-

sections

2 and 3, the casingsection 2 being interiorly threaded at one end, as at l, to receive the reduced eXteriorlythreaded neck 5 of the section 3, but the casing may be formed of one casting, so that the and in this case the pipe-section 7, tted in the lower end of the valve-casing, is joined with or leads from the ordinary hydrantvalve, which is opened and closed in the usual way to control the flow of water, and in this adaptation of the waste-valve the pipe-seetion 7, fitted in the upper end of the valvecasing, forms a part of the hydrant and leads to the discharge-spout thereof, so with this explanation it is believed that the arrangement of the valve in the line of piping will be understood.

Referring particularly to Figs. l and 2 of the drawings, the valve-casing l is provided intermediate of its ends with an interior annular valve-seat 8, below or at one side of which the valve-casing is formed with a cylindrical guide-bore 9, while above or at the opposite side of the valve-seat 8 the casing is provided with an enlarged valve-chamber l0, directly above which and within the outlet or delivery neck of the casing the latter is provided with a transverselyarranged waste pipe or passage ll, opening at its opposite ends, as at l2, at the outside of the valvecasing and provided centrally between said open ends l2 and in one side with a drainport 13, through which the surplus or standing water above the valve is designed to pass into the pipe or passage ll and thence to the exterior of the valve-casing l. p

The transversely-arranged waste-pipe ll is sufficiently small in diameter so as not to interfere with the free iiow of water through the outlet coupling-neck of thc valve-casing, and arranged to play within the enlarged valve-chamber l0, below the waste-pipe l1,

ICO

is a hollow cylindrical plunger-cup 14. The hollow cylindrical plunger-cup 14 is slidably mounted to work in the cylindrical guidebore 9 of the valve-casing, and is provided with a closed end 15, having an annular valveshoulder 16, adapted to work onto the interior valve-seat 8 when the plunger-cup is in its normal closed position. The closed end 15 of the plunger-cup 14E is further provided with small relief openings or perforations 17 and with a central pin-opening 18, adapted to slidably receive therein a movable valvepin 19, provided With a disk head 2G at one end, which works below the closed end 15 of the plunger-cup, and opposite its disk head 20 the said valve-pin 19 is provided with a point 2l., adapted to seat itself in the drainport 13 of the pipe 11. A pin-adjusting spring 22 is coiled on the valve-pin 19 and is connected at one end to such pin and bears at its other end against the closed end 15 of the plunger-cup, so as to normally project the pointed end of the pin beyond the closed end of the plunger-cup and in close proximity to the drain-port 13 in alinement therewith. The said plunger-cup is further provided in diametrically opposite sides between its ends with the enlarged side ports 3, which are sufficiently large to permit a free flow of the liquid therethrough and thereby not decrease the volume of water passing through the pipes connected with the valve-casing.

Assuming the construction described to be used in connection with hydrants, the parts of the valve normally assume the positions illustrated in Fig. 1, but when the hydrantvalve is opened the water enters at the lower end of the valve-casing and passes into the hollow plunger-cup 14. The pressure of the water raises the plunger-cup and carries the point of the valve-pin into the drain-port 13 to close suoli port immediately in advance of the ports 23 being uncovered by passing above the interior valve-seat S. The press ure of the water continues. to elevate the hollow plungercup until the ports 23 are completely uncovered to allow the water to freely pass through the line of piping and the valve-casing to the point of use without escaping through the drain-pipe 11 of the valve-casing, it being understood that while the water is passing through the valve-casing there can be no Waste, because the pressure against the hollow plunger-cup is constant and keeps the valve-pin seated in the drain-port of the wastepipe. When the water is shut off, the weight of the column of water above the valve, with the aid of the spring 22, instantly forces down the plunger-cup, and it in turn engages with the disk head 2O of the valve-pin and draws the point of said pin out of the drain-port 13, thereby allowing all the water above the valve to escape through said drain-port and the Waste-pipe. Vhen the supply of Water is cut off and the plunger-cup is closed onto its valve-seat 8, the small relief openings or perforations 17 allow the water to quickly pass through the same, so as to reduce the resistance offered to the quick closing of the plunger-cup and the consequent uncovering of the drain-port 13, as will be readily understood by those skilled in the art.

In Fig. 3 of the drawings is illustrated a modification of the valve in which the use of a spring in connection with the valve-pin and the plunger-cup is entirely dispensed with, and in this modilication of the invention the valve-pin 19 is provided directly adjacent to its point 2l with a stop-collar 25, adapted to engage with the upper side of the closed end of the plunger-cup to limit the downward movement of the valve-pin when it is uncovering the drain-port and to hold said valvepin in a proper position. In addition to being provided with the collar 25 the valve-pin 19 in the modification referred to is provided at its lower'end with an enlarged disk head 26, which is of a diameter substantially agreeing with the internal diameter of the plungercup, so as to form a piston loosely working within said plunger-cup, and when the collar 25 of the valve-pin 19 rests against the closed end of the plunger either in its elevated or lowest position the periphery of the disk head 26 should project slightly belowl the upper edges of the side openings 23 of the valvecasing. I

In the modified construction just described the water on being admitted to the hollow plunger-cup first impacts itself against the disk or piston head 2G of the valve-pin and immediately forces the point of the valve-pin into the drain-port 13, so as to close such port, and after this operation occurs the pin remains stationary while the pressure of the water forces the hollow plunger up to a height sufficient to uncover the enlarged side ports 23 and allow the free and uninterrupted passage of the liquid or water through the valvecasing.

In the construction referred to the operation of the valve is positive, and no matter how slight the pressure of the water may be the waste-pipe will be closed first, so that no water can escape until the hydrant is shut off, and, furthermore, should the valve controlling the inlet of water into the casing 1 of the waste-valve fail to operate at any time forany reason the defect will be immediately known, as the automatic waste-valve will be instantly closed, and water instead of wasting into the ground will lill up the hydrant and attract attention by wasting out of the spout.

The preferred forms of the invention and the manner of using the same have been described; but when the valve is used for the purpose of draining water of condensation from steam-pipes after the live steam is cut off it is necessary to place the valve below the steam-pipe and invert the parts, as illustrated in Fig. 4 of the drawings. In this arrangement of the valve it is necessary to provide IOO IIO

for normally holding the plunger-cup closed on its seat S, and to provide for this a spring 27 is interposed between the closed end of the cup and the shoulder of the casing, formed at one side of Idie waste-pipe ll. lVhile the movable valve-pin 19 might be employed in connection with the plunger-cup when supported by the spring 27, such plunger-cup may be provided at its closed end with a fixed valve-point 19a, adapted to seat itself in the drain-port 13 and subserve the same function as the valve-pin 19, hereinbefore fully referred to.

The operation of the construction illustrated in Fig. 4c is in all respects similar to the operation of the valve described in connection with Figs. l, 2, and 3, and at this point it will be noted that while in Figs. l and 2, and also in Fig. 3, no spring is necessary for the closing of the plunger-cup onto its seat still a spring similar to the spring 27 may be employed to insure this operation, and various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
