HYDBANT.

Specification of Letters Patent.

Patented Sept. 1'7, 1912.

To all whom t may concern:

Be it known that I, GEORGE W. HAYDEE,

a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented `a new and useful Improvement in yHydrants, of which the following is a specification.

This invention relates to a hydrant which has a main port that is closed by a large swinging valve, and which has a drain outlet that is closed by a small reciprocating valve, the drain outlet being closed when the main port is opened, and when the main port is closed the drain outlet being opened to permit all water to drain from the hydrant and stand-pipe.

The object of the invention is to provide a simple, cheap, readilyassembled and easily removable valve organization which is so designed that the main valve is kquickly opened and tightly closed by powerful mechanism, and the drain valve is positively opened by the closing of the main valve, the parts being so connected and operated that relative adjustment between the valves is not necessary, consequently there is no chance for the parts to get out of adjustment or to be improperly assembled, either when first put together or after having been taken apart for repairs.

Figure 1 of the accompanying drawings shows a central vertical section of the lower section of a hydrant casing provided with an organization which embodies this invention, the main valve being shown closed and the drain valve shown opened. Fig. 2. shows a similar section with the main valve opened and the drain valve closed. 4

The casing 1 is usually cast to shape of iron with an inlet 2 on one side that is adapted to be attached to the water main, and an outlet 3 at the top that is designed to be connected with a hydrant stand-pipe of common construction. Adjacent to the inlet is the main port which is surrounded by the valve seat 4. The main valve 5 is carried by an arm 6 which is hinged by a pin 7 to the casting 8. This casting rests upon the inside of the bottom of the hydrant casing and at its lower end has a hollow hub 9 that fits into an opening through the bottom of the hydrant. Stepped in a socket in the upper end of the casting is the lower end of the spindle 10. A length of this spindle is threaded, and on this thread is a nut 1l. A link 12 connect-s this nut with the back of the free end of the main valve arm. When the spindle is turned the nut is carried up or down the threaded portion according to the direction of rotation, and through the link swings the valve toward or from the seat around the main port.

Screwed into the hub at the lower end'of the casting `which forms the bed for the valve arm and the step for the spindle, is a sleeve 13. The upper end of this sleeve pro-` vides a seat for the drain valve 14. Apaeking 15 may be larranged around this sleeve and the lower end of the casting for making tight the joint between the wall of the casting and the wall of the opening through the bottomV of the hydrant. This packing can be held in place by a tubular nut 16 screwed upon the end of the sleeve. The drain valve, which is adapted to open and close the passage through the sleeve, has guiding prongs 17 that project into the sleeve and has a stern 18 that is guided by an opening in the casting.

Projecting from the casting are lugs 19, and pivcted between these is a lever 20. One end of this lever is forked and embraces the drain valve stem beneath a collar 21. The other end of this lever extends upwardly into the path of the arm that carries the main valve. Just as the main valve is closedk the arm which carries it engages the free end of the lever and causes it to raise the drain valve from its seat. This allows the escape of all water from the hydrant casing and stand-pipe to a drain when the main water port is closed. When the main water valve is opened, the swinging up of the main valve arm releases the drain valve lever and allows the drain valve to shut under the water pressure so that when the main port is opened, the drain port will be closed. A headed stud 22 may be passed thro-ugh an opening 28 in the valve arm 6 into the lever 20 (Fig. l). When the arm is swung up, if the drain valve sticks or is sluggish in its movement, the head of the stud will be engaged so as to move the drain valve toward its seat. This may be accomplished by arranging a cam 24C on the valve arm in such position that when the arm is raised the cam will en age the end of the stem and close the drain valve.

The construction of the mechanism which embodies this invention is very simple. The

' can be proper main valve is moved positively and powerf fully and yet rapidly so that the water port` can be closed tightly or opened quickly. The Y drain port isl positively opened ywhen the main port is closed so as to insurea proper draining of the hydrant. The means provided Jfor opening the drain valve are very simple,'they require no adjustment, and oonsequently they cannot be'assembled or re-I assembled out of time. All the parts are so eonneeted that the main valve and drain valve can be readily lifted by the spindle out of the hydrant easing, after the main valve has been opened, for the purpose of oleaning, renewing or repairing, and the parte 7ly re-assembled without disturbing the easing.

The invention claimed is: 1. A hydrant having a easing with a main port and a drainoutlet, a casting seated on the inside of the bottom of the easing, an arm hinged to theeasting, a valve mounted on the arm, a spindle `stepped in the casting, a portion of said spindle being threaded, a nut moving on the threaded portion of the, spindle, a link'connectingthe nut and thef valve arm, whereby the rotation of the spindle eauses thevalve to swing toward and i from the main port, a valve adapted to close therdrain outlet, and a lever adapted to be engaged by the valve arm and to lift the drain valve when the main valve is closed.

Y 2. A hydrant having a easing with a main 'port andra drain outlet, a casting yremovably seated in the bottom of the easing, an arm'hinged to said Casting, a valve carried by the arm, a spindle stepped in said casting, 'a portion of the spindle being threaded, a nut moving on the threadedportion of the Spindle, a link eonneeting the nut and the valve arm, whereby when the spindle is rotated, the valve is swung toward and from the main port, a sleeve screwed into the lower end of the casting, the upper end of vthe sleeve forming a valveV seat, a valve having a stem guided by the casting, said valve being adapted to seat on the end of said sleeve, and

a lever engaging thev valve stem, said lever extending into the path vof the main valve arm and engaged thereby when the main valve is closed for lifting the drain valve from its seat. v
