IMPROVEMENT IN lHYDRANTS.

Specification forming part of Letters Patent No. l lAl 7, dated May 26, 1874; application led Apr-i1 20, 1814.

To all whom it may concern:

Be it known that I, JOSEPH V. S. MIsKELLY, 0f Baltimore city, State of Maryland, have invented a new and Improved Hydra-nt; and I do hereby declare that the following is a full, clear, and exact description ot' the same, ret'- erence being had to the accompanying drawing, forming a part of this specification, in which the tigure is an elevation, partly in section.

This invent-ion contemplates an improvement in the construction ot' hydrant-s used in connection with the water-mains ot' cities, or wherever a current ot water has sutiicient fall from its source to carry it up to the desired point of discharge.

These are usually open to two objections, one being that they receive drainage-water, and the other that the waterremaining in the tube after use is liable to freeze. The novel means which I employ to overcome both these difficulties will iirst be fully described, and then pointed out in the. claim.

A represents the pipe leading from main, and B the chamber into which the water is received therefrom. O is a valve that moves up to its seat U', and is held closely thereto by a spring, D, placed on the inside of chamber or cylinder B, and pressed against the bottom of cylinder by a nut, E, with one or more intermediate washers. F is the hydrantplunger, having an end disk, j', and proper iexible packing j". This plunger is a tube, and extends up, forming under the ground no joint into which surface drainage can enter, butl jointed to the T-tube G, which receives the discharge-spout H and post I. On top ot' the latter is pivoted the end of hand-lever J,

that is fulcrumed in the slotted rigidly-fast-A ened bracket K. L is a cap, whose liange, l, rits upon a corresponding` fla-nge, b, of chamber B, while between the two is made a watertight joint with suitable packing. M is a guide-tube, which may be screwed into the cap L, or cast therewith. Between the upper end of this tube M and the T-tube G is located a strong spring, O, resting preferably at each end against a washer, 0.

The operation is as follows: Willen pressure is broughtto bear upon the post I, the latter, together with the spout H and plunger F, is carried down fard, overcoming the upward tension ot' spring O, and causing the plungerdisk f to strike the nut E. This overcomes the upward tension ot' the spring D, forces downwardly the valve O, and admits water into chamber B, the water then coursing, by the impulsion ot' its back pressure7 up through the plunger and out of the discharge-spout. As soon as the power exerted on the post- I by the lever or other means ceases, the spring O lit'ts the post, spout, and plunger, while the spring l) elevates the valve C to its seat.

The tube M serving as a guide-tube, and having no joint near the surface of the ground, all drainage is eii'ectually excluded therefrom. On the other hand, after the disk fhas moved up, a vacantspace is always left in the chamber B, amply sufficient to receive all the water which is arrested in the plunger by the closing of valve O.

Having thus described my invention, what I claim as new islhe combination ore the chamber B, having downwardly-opening spring-valve O D, pistoned tube F j', serving both as plunger and water-conduit, guard-tube M, spring O, T-tube G, and post I, in the manner and for the purpose specified.
