JOHN N. POAGE, OF CINCINNATI, OHIO.
IMPROVEMENT IN BALANCED VALVES FOR STAND-PIPES.
Specification forming part of Letters Patent No. 141,815, dated August 12, 1873; application filed May 20, 1873.
To all whom it may concern:
Be it known that I, JOHN N. POAGE, of Oincinnati, in the county of Hamilton and in the State of Ohio, have invented certain new and useful Improvements in Balanced Valves; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing makin g a part of this specification, in which- Figure 1 is a side elevation of the lower portion of a watering-column containing my improved valve. Fig. 2 is a vertical central section of the same, showing the valve closed. Fig. 3 is a like view of said device with the valve opened; and Fig. 4 is a perspective view of the valve, valve-seat, casin g, &c., detached.
Letters of like name and kind refer to like parts in each of the figures.
The design of my invention is to improve the action, decrease the liability to obstruction, andrender more easy the operation of a class of valves employed in the water-supply apparatus of railways; and it consists, principally, in the peculiar construction of the valve and its surrounding casin g and their combination within the water-pipe, substantially as and for the purpose hereinafter specified. It consists, further, in a valve, valve-seat, and chamber, combined with each other and with the surrounding casing in such a manner as to rotate freely upon a vertical axis within the latter, substantially as and for the purpose hereinafter shown. It consists, further, in the construction of the main valve, drain-valve, casin g, and pipe for sustaining said drain-valve, substantially as and for the purpose hereinafter set forth.
In the annexed drawing, A represents a hollow metal cylinder, constructed with open ends and partially open sides, and secured to or upon the upper end of a valve-chamber, B, which has the general form shown in Fig. 1, and is provided with a branch pipe, B, that extends horizontally outward from one side. The upper end of the chamber A is inclosed by means of a removable head, A, the upper end of the valve-chamber or box B by means of a permanent head, I), while the lower end of the latter is provided with a detachable head, 0, and in and through each of said heads is provided a central opening, which has a diameter equal to about one-half the interior diameter of the part to which it is attached. Fitted loosely into the opening within the head A is a pipe,
D, that is provided upon its lower end with a suitable annular flange, d, by means of which a short section of pipe, E, provided with a coupling-flange, e, is attached thereto, said section extending downward through the head 11 into the valve-box B. The pipe E is loosely fitted to the opening within the head B, and rotates freely within the same, while a water-tight seat, E, which corresponds to and receives the face 9 of the upper end of a valve, G, which valve, as seen in Fig. 4, is formed of a hollow straight cylinder having its upper end flanged so as to increase somewhat the horizontal dimensions of its face. The lower end of the valve G fits into a short cylindrical casing, O, which forms a part of the head 0, and extending above and below said head has its ends uninclosed. A water-joint is formed between the lower portion of the valve and the interior of the casing O by means of an annular gasket of rubber or leather, 9, placed against the end of said valve and a metal disk, G, placed beneath said gasket, and by means of suitable screws or bolts drawn upward against and caused to compress the same. The lower open end of the casing ()"being placed in communication with thewaste-water pipe, thelower end of the valve is entirely freed from the upward pressure of the water.
This construction of the valve and its casing enables any desired proportion of the upward pressure of the water to be counterbalanced, as by increasing or diminishing the diameter of the lower or incased portion of said valve the upward pressure will be correspondingly decreased or increased as the relative areas of the upper and lower ends approach toward or recede from each other. A rod, H,
attached to the lower end of the valve G, and
passing upward through the pipe D, furnishes a means for moving said valve vertically away from or toward its seat so as to open or close the passage between said valve and said standpipe.
In order to prevent an escape of water around the rod H, and to cause the escape of water remaining in the stand-pipe when the valve is closed, the following-described appliances are employed: A tube, I, somewhat larger than the rod H, is secured within and passes downward through the upper inolosed end of the stand-pipe D, and at its lower end is provided with a cylindrical disk, K, which corresponds to and closely fills an opening, 9, formed in the center of the valve G. The lower portion of the opening g is enlarged, as shown in Figs. 2 and 3, and in and through the disk G is provided a number of passages for the escape of water from the interior of the valve. From equidistant points around the periphery of the disk K a number of guides or wings, k, which extend vertically upward, and bearing against the sides of the opening g of the valve G, insure the central position of said disk or reliefvalve K, when moved below the point of enlargement of said opening. The valve K is now adjusted vertically, so as to cause its upper edge to occupya position below the upper end of the enlarged portion of the opening g when the valve G is closed, as seen in Fig. 2, so as to furnish a free passage for water from the stand-pipe D to the waste-water pipe, while by moving said main valve downward, so as to admit water to said stand-pipe, the smaller portion of said opening 9 will be caused to inclose said relief-valve and prevent all downwardpassage of water to the waste-pipe.
The device is now complete, and possesses the following-named advantages: First, the valves may be placed at any distance below the surface of the ground which convenience or situation may render desirable, and without other protection will be entirely free from all liability to injury from freezing. Second, the means employed for removing water from the stand-pipe after the main valve is closed are efficient, simple in construction, not liable to get out of order, and add but slightly to the cost of the apparatus. Third, the construction and combination of the stand-pipe, valves, and valve-box enable said pipe to be turned in any direction, or moved vertically within its casin g withoutinterferin g with the action of said parts.
Having thus fully set forth the nature and merits of my invention, what I claim as new 1s-- 1. The valve-box B, casing C, stand-pipe D, valve-seat section E, and valve Gr, when constructed and combined to operate substantially as and for the purpose specified.
2. The valve G and valve-seat section E, when constructed and combined with the valvebox B and easing O, substantially as and for the purpose shown.
3. The valve G, provided with the opening 9, the casing O, the seat-section E, the operating-rod H, the tube I, and the relief-valve K, when constructed as shown, and combined with each other substantially as and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 17th day of May, 1873.
JOHN N. POAGE.
