UNITED STATES PATENT OEEICE.
JACOB FRICKER, JR., OF CINCINNATI, OHIO.
IMPROVEMENT IN EXTENSION FIRE-HYDRANTS.
I, J AGOB FRIGKER, Jr., of Cincinnati, Hamilton county, State of Ohio, have invented a certain new and useful Extension Fire-Hydrant, of which the following is a specilica-tion:
Nature and. Objects of Invention.
My invention consists of a tire-hydrant having an extensible stoel; for the purpose of enabling the discharge-nozzles to project above the ground, when the hydrant is required for use, in the attachment and supply of tire-hose, and to fall below the ground when not required for use, in such a way that the pit in which it is situated may be covered by a cap on alevel with the street. The object of my invention is the production of a hydrant adapt-ed for direct attachment to the intersection of two or more water-mains of a street, which shall be complete in itself, and yet have no projection above the surface of the roadway when not in use.
Description of the Accompanying Drcming.
Figure l is a vertical section of my improved tire-hydrant connected to the intersection of four street mains. Figure 2 is a horizontal cross-section through the valves governing the discharge-nozzles. Fig. 3 is a horizontal cross-section through the valve-chamber governing the supply of water to the stock.
General Description.
A is the cross, which serves as a connecting socket for all four pipes of the intersection. Bis the main valve-chamber, connected to the cross A by bolts C. The main valve D seats against the gasket E, and has grooved wings (l formed upon it, which are prevented from rotating by set-screws F, whose points iit grooves d of the wings d. The screwthreaded stem Gr of the valve rotates in the stuing-box H in the manner shown, and is operated by a wrench or otherwise. The stock I is att-ached to the chamber B by anges b, water-tight, and has a stuiing-box, J, at the upper end, whose gland K retains the double cup-leathers77 L in place, which I use preferably to pack the extension part I of the stock. The latter is turned off smoothly on the outside to it the bored gland K, and is kept Water-tight by cup-leathers L. It is also secured to the head M of the hydrant, which is constructed with one or more dischargenozzles, N, each fitted with an independent valve, P, tapering in vertical section, retained between the tightening jaws n, and operated by the screw-spindle Q. The jaws serve to crowd the valve against its seat when closed. Rods lt, attached to the head M, and sliding through notches@ in the stuffing-box J, serve to prevent, the head M from rotating, and also prevent by provision of nuts S on their ends, a too great extension of the stock, the nuts stopping when the stock is sufficiently extended against the tlan ges ofthe stuffing-box J.
The hydrant is so constructed and attached to the mains that when not extended at all, the top shall be below the surface of the street sutticiently to permit a cap to cover the'pit the hydrant is located in, the face of the cap being iiush with the roadway. W'hen required for the attachment of hose the street cap is removed, the valve D opened, and`the stock extended by the hydrostaticpressure of the water in such a way that the nozzles N are elevated above ground. As many lines of hosel can then be attached as there are nozzles, and, owing to the stock receivingit's supply from many directions7 the hose is at all times fully supplied. When it 'is required to lower the extension part ot' the hydrant afteruse, the valve D is closed and 'a vent, T, will permit the extension l to fall by its own gravity. The exterior surface of the part of the extension -I which slides in the stuffing-box may be plated with nickel, or otherwise protected from corrosion.
The hydrant may be used for the attachment of hose to be used directly upon a fire, or for the attachment of the suction-hose7 of a lireengine, thereby dispensing with the use ot eisterns, employed in many large cities.
