JOHN J. SULLIVAN, OF HOLYOKE, MASSACHUSETTS.
HYDRANT.
SPECIFICATION formingpart of Letters Patent N 0. 673,666, dated May '7, 1901.
Application filed December 3, 1900. Serial No. 38AM. \No 1110(181-4 To all whom it may concern:
Be it known that I, J OHN J. SULLIVAN, a citizen of the United States of America, and a resident of Holyoke, in the county of Hampden and State of Massachusetts,have invented certain new and useful Improvements in Hydrants, of which the following is a full, clear, and exact description.
My invention relates to an improvement in hydrants of a class in which there is a main valve which closes against the valve-seat in the usual manner, combined with a smaller valve secured to the valve-stem above the main one and which smaller valve is of very little less diameter than the cylindrical waterpassage in the lower end of the passage and in which it is located when the flow of water is shut off.
The object of the invention is to simplify the construction of the parts for an easilyadjusted assemblage and connection on the valve-stem or shaft and to permit readily a removal of the main valve as occasion may require.
The accompanying drawing represents a vertical section of a hydrant which embodies my invention.
A represents the hydrant-casing, which may be of any suitable construction and which is secured to the water-main B at its lower end in the usual manner. The hydrant-casing has in its lower end the cylindrical bushing a, which at its lower end is constructed with a downwardly-flaring valve-seat b.
Secured to the lower end of the valve-rod O,the lower portion of which is screw-threaded from its end'upwardly, as indicated at 10, is the main valve D, of any suitable construction,and' which when closed fits tightly against the tapering valve-seat formed upon the lower end of the cylindrical water-passage F, placed in the lower end of the casing A, where it makes connection with thewater-main B.
Secured to the valve-stem C by screwthreading thereon at a short distance above the main valve D is a smaller thin cylindrical valve or disk G, which is of very little less diameter than the cylindrical passage F. These two valves are separated but a very slight distance, as shown, and the valve G enters the lower end of the cylinder F before the valve D comes in contact with its seat.
As the valve G is of smaller diameter than the main one, D, as this smaller valve G enters the lower end of the cylinder F the flow of water through the hydrant or plug is so gradually cut off that the fiow in the main B is checked, and the consequence is that when the main valve D seats itself there is but a very small amount of flow for it to check, and hence the water in the main does not surge back and forth in such a manner as to cause waterhammering, as is done when the flow is suddenly shut off by quickly closing the valve D in the usual manner.
As specifically shown and as materially contributing in the composition of the present invention for convenience,practicability,
'and general availability of the invention,
the secondary or diametrically smaller disk or plinth valve G is constructed integrally with a neck d and a flange-rest (1, extended therebelow, and with a concentric polygonal axial projection f extending thereabove. This integrally-formed part f G d is axially bored and screw-tapped and screw engaged and adjusted on the threaded valve-rod. The valve D,as shown, is in the form of a frustoconical part, the upper face of which is applied in bearing against the bottom of the said rest (1, which is a part of the secondary valve G. The clamping member h, having the screw-threaded bore therethrough and provided with the polygonal depending projection k isset up against the under face of the valve D and confines the same positively against the rest d.
iis a check or look nut to be set against the part f, formed as one with and extending above the secondary valve, and j is a check or look nut which screws on the lower end portion of the valve-rod, these two lock-nuts together preventing any change in the adjustment of the valve devices.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
In a hydrant, the combination with the vertical waterway, which is connected with the water-main, and which has, at its lower end, a main-valve seat, and thereabove, its passage F of cylindrical form, of the valve-rod C, the lower end portion of which is screwthreaded; the integrally-formed device conengaged on the'lower portion of the valve-rod below the main valve; and the lock-nuts z and j screw-engaged on the threaded valverod respectively above and below the partsf I5 and k substantially as described. I
Signed by me at Holyoke, Massachusetts, this 22d day of October, 1900.
