HYDRANT.

' To all whom it may concern:

Be it known that I, GEORGE M. SELDEN,

' Fig. l, and Fig. 3 represents a section showing the operation of the valves.

In the drawings, A represents the base of the hydrant which is generally cast with a short inlet knee or pipe F.

B represents the top of the hydrant and is cast with an outlet pipe or conductor C. rIhe bottom of B screws into the top of A, as seen at i, Fig. 3, and has fastened to its lower end a narrow cross piece B is also provided with an internal rod or spindle J to the lower end of which is fastened a valve I, while its upper end extends up through a hole in the top of B, and is provided with a screw thread, upon which is screwed the connection piece D, after a suitable packing a, has been slipped on.

Before the part B is screwed into A, aV

valve seat piece c is screwed down upon a packing ring f, the spindle Gr, with its valve H, having been previously placed in position as shown in Fig. 3.

C is provided with an internal screw thread for the reception of the delivering pipe, while the outer end of F is provided with an external thread for the reception of the usual connections E, or these connections may be made by soldering or otherwise.

c is an extension to allow of a support to the lower end of spindle G.

b l are ear pieces Yby which to fasten the hydrant in any well known manner.

in dark lines Fig. 3, whereby the water is allowed to flow through pipe F, as indicated by arrows at F', thence up through A, and out at @,-the packing a, being pressed against the top of B, preventing any water passing up and out of the side of spindle J, where it passes through the top of B. rThe arrangement should be such as to enable the operator to fasten down the rod by which spindle J and valve I, are operated.

Then it is desired to shut the water off, the fastening which holds spindle J, down is to be removed, when the force of the water against the bottom of-valve I, forces it up against its seat h, thereby preventing all further flow of water; while the water then in the outlet pipe connected with C, flows back and out under packing a, (which is always raised when valve I, is closed) as shown by red arrows Fig. 3. It will thus be seen that the operation of my hydrant is almost self-acting, and that it-s simplicity is such that it is not ,liable to be displaced by unskilful operators. Y

Then it is necessary to repair any of the' pipes or valves above A, the water does not have to be shut off from the main pipe, since by simply unscrewing B, spindle Gr, and valve H, rise up by the action of the water until valve II, strikes against valve seat e, when the water is prevented from flowing, and the part B, together with valve I, and pipe C, can all be removed for repairs.

When the part B. is screwed in again, as soon as the narrow piece g, which extends across its bottom, strikes the upper end of spindle G, which projects above valve H, as seen in the drawings, spindle G, with its valve I-I, are forced down, whereby the water is again allowed to flow freely up into B, as indicated in Fig. 3. By this arrangement, all necessity lof digging down 4in. the streets or under pavements in order to shut oil the water, when it is necessary to'repair any of the parts above it is avoided.

By the use of a box to prevent dirt from falling into the end of A, B, can be unscrewed and taken up, although many feet under ground, repaired and then put down and screwed into A#L -the operation being conducted by the most simple device. For instance by running do'v'vn 'il piece 'of board bevalve seat e, and sections A, substantially tween the end of C, and D, and then turnas set forth. l0 ing it, B can be unscrevved with ease. In Witness whereof I have hereunto sub- Havng described my invention What I scribed my name. claim and desire to secure by Letters Pat- GEORGE M.
