Specification of Letters Patent.
Patented Dec. 19, 1905.
Application filed April '7, 1904. Serial No. 201,965-
To all whom it may concern:
Be it known that I, CLAUDE L. Howns, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Hydrants, of which the following is a specification.
This invention has relation to fireplugs or street-hydrants, and has for its object to provide an improved valve mechanism for permitting the escape of water contained in the body of the plug after the main valve is closed.
The object of the invention is to provide an improved waste-valve mechanism so constructed and arranged that the waste-port will be opened automatically by the seating of the main valve and will be closed by water-pressure when the main valve is open.
To this end the invention consists of a hydrant having certain improvements illustrated upon the accompanying drawings, described in the following specification, and pointed out in the appended claims.
Of the drawings, Figure 1 represents a hydrant, partially in section, embodying the invention. In this figure the waste-valve is shown as closed. Fig. 2 represents the hydrant in section and shows the waste-valve open. Fig. 3 represents a section on the line 3 3 of Fig. 1.
Referring to the accompanying drawings, which it will be understood illustrate one embodiment of the invention to the details of construction of which the invention is not intended to be limited, (1, indicates the up standing shell or casing, which forms the body of the hydrant. The upper portion of this shell is provided with suitable eduction-ports. The lower portion of the casing or shell is attached to the water-main b, the connection between the main and the casing being conventionally illustrated. The casing is provided with the internal valve-seat c, the port through which is adapted to be closed by the valve d upon the vertically-adjustable stem (2, which is raised and lowered by any suitable means.
6 indicates the waste-port. It consists of a short pipe-section or nipple, which in the present form of the invention is screwed into the side of the casing a above the valve-seat 0, so as to communicate with that portion of the chamber in the casing or shell which is out ofi from the main 6 when the valve (Z is closed. Connected to this pipe-section or nipple is a conduit e, which may lead to a convenient manhole or sewer or else discharge into the gutter adjacent which the hydrant is placed. This waste-port e is adapted to be closed by a waste-valve f. The valve is shown as oylindrical in form and plays in the concave seat in the inner end of the pipe-section or nipple e. The said valve is passed through the internal flange c in the shell 0, which supports the valve-seat c, and on its lower end it is formed with an enlarged head f, which is concave on its face, as shown. The diameter of the headf is considerably greater than the diameter of the valve f, and the said head is exposed to the pressure of water in the main 1) and in the shell at below the valve-seat a when the mainvalve d is raised. The said head f constitutes, as it were, a piston which slides in the cylindrical socketf in the flange c.
The main valve (1 is provided with a finger d whichis in alinement with the end of the valve f and which when the valve (Z is seated forces the valve f downwardly against the pressure of water in the main, so as to open the waste-duct e and permit the escape of the water in the shell a. When the valve (1 is raised, however, the finger (1 in rising permits the pressure of the water in the lower extremity of the casing a and in the main 5 to force the valve f upwardly and close the waste-port e.
The waste-valve is entirely automatic in its operation, being moved in one direction by the main valve to open the waste-port and being operated in the other direction by the pressure of the water to close the wasteort. p The simplicity of the device is one of its most attractive features, for it cannot get out of order eXce t, perhaps, from excessive wear, and it adds but little to the cost of the hydrant.
It is not at all essential that the valve f should have the length of movement which it is illustrated as having. In fact, the wastevalve mechanism is illustrated as exaggerated in size with relation to the remainder of the hydrant.
Having thus explained the nature of the invention and described a way of constructing and using the same, althou h without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is 1. In a street-hydrant comprising a casing with an internal valve-seat and main valve, a waste-port communicating with said cas- IIO ing, a waste-valve bodily movable in a direction parallel with the movement of said main valve and across said port and adapted to be port and closed by the water-pressure in the supply-chamber, and means on said main valve for moving said waste-valve to open said waste-port when said main valve is closed upon its seat.
3. In a street-hydrant comprising a casing with an internal valve-seat and main valve, a waste-port communicating with the discharge-chamber of said casing, a waste-valve bodily movable in a direction transverse to the flow through said waste-port, said wastevalve being normally closed over said wasteport by the water-pressure; and means on said main valve for moving said waste-valve to open said wasteport when said main valve is closed upon its seat.
4. In a street-hydrant comprising a casing with an internal valve-seat and main valve, a waste-port communicating with the interior of the casing above the main-valve seat, and a plunger-valve bodily movable in a chamber communicating with the casing below said valve-seat, and adapted to be bodily moved across said port by the pressure of water below said valve-seat to close said wasteport when said main valve is unseated, and means on said main valve for moving said plunger-valve to open said waste-port upon the closing of said main valve against its seat.
In testimony whereof I have afiixed my signature in presence of two witnesses.
