HYDRANT.

SPECIFICATION forming part of Letters Patent No. 448,096, dated March 10, 1891.

Application filed August 16, 1390. gerial No. 362,181. (No model.)

To all whmn it may concern:

Be it known that I, WILLIAM R. 'lHRoPP, of Trenton, in the county of Mercer and State of New Jersey, have invented a new and Improved Hydrant, of which the following is a full, clear, and exact description.-

My invention relates to improvements in hydrants, such as are ordinarily erected in towns and cities for the use of the fire department, and the object of my invention is to produce a hydrant in which the valve regulating the water-supply may be easily controlled.

To this end my invention consists in certain features of construction and combinations of parts, which will be hereinafter fully described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forniinga part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a broken vertical section of the hydrant embodying my invention. Fig. 2 is a horizontal section on the line 2 2 of Fig. 2, and Fig. 3 is a horizontal section 011 the line 3 3 of Fig. 1.

The shell A of the hydrant is substantially like the ordinary form, andis' provided at the base with a laterally-extending flange A which is coupled to the flange B ofthe supply-pipe B in the usual manner. The hydrant A has a horizontal partition C extending across the lower part thereof, through which is a vertical opening 0, the partition having an annular shoulder c on its under side, to which the valveseat D is attached.

.A valve-stem E extends vertically through the hydrant, the lower portion of the valvestem being reduced, as shown at E, and provided with a square collar c, free to turn, and which is held in the square socket b in the lower portion of the pipe 13, the socket preventing the collar from turning and serving as a guide or box for the valve-stem, the height of the socket Z) being sufficient to allow for the necessary vertical movement of the valve-stem. The valve-stem E may be provided at the top with any of the common forms of mechanism for operating it, said mechanism not being shown in the drawings, as it forms no part of my invention. The

valve-stem at a point adjacent to the valveseat D is provided with a valve consisting of two disks F and G, the lower disk F being held in place by a nut f and the upper disk G having a hub g, by which it is held to the stem. The upper disk is small enough to pass freely through the opening in the valve-seat and the lower disk has a plain uppersurface, corresponding in size to the size of the valveseat, so that when raised it will fit closely upon the same.

A packing-piece H, which is preferably of rubber, but may be of any material suitable for the purpose, is held upon the upper surface of the disk F, it being arranged to come between the disk and the valve-seat D, so that when the valve-stem is raised the packingpiece will be pressed firmly against the valveseat and a water-tight joint made.

A horizontal duct C leads from the lower portion of the hydrant to one side thereof, the duct being located between the flangeA and the partition 0, and opening vertically from the upper portion of the hydrant into the duct is a conical perforation 0 A rod J is mounted horizontally in the projection a of the hydrant, said rod being located directly above the duct 0', and pivoted on the rod is an inwardly-extending latch K, the inner end K of the latch being bent downward, so as to impinge upon the upper surface of the disk G. The latch K extends horizontally above the opening 0 and 011 the under side of the latch is a conical plug 70, which fits nicely in said opening, so that when the latch is dropped the opening will be closed.

The operation of the hydrant is as follows: lVhcn the valve-stem E is forced downward, the collar 6 travels downward in the socket 'b, and the valve F G is forced downward and away from the valve-seat D, so that water from the pipe B flows freely through the opening in the valve-seat and the opening 0 in the hydrant. \Vhen the valve is opened, as described, the weight of the latch K causes it to drop and the plug is forced into'the opening C and the hydrant will not leak. hen

the valveis closed, the disk Gstrikes the bent end K of the latch, thus raising the latch, and the water in the hydrant flows out through the opening-O and duct- C', and consequently there will be no danger of the hydrant being In a hydrant, the combination, with the verfrozen up and becoming inoperative. tically-movable valve-stem having a collar It will be readily seen that the inner end loosely mounted on the lower end thereof,ol of the latch K might be bent upward instead a socket vertically aligning with the valve- 1:, 5 of downward, so as to engage a valve closing; 1 stem and adapted to hold the collar from downward instead of upward, which would turning substantially as described. be merely the inverting of the valve shown, i Tn-LIAM R THROPR with the necessary mechanical changes.
