IMPROVEMENT IN HYDR'ANTS.

Specication forming part of Letters Patent No. [78.129, dated May 30, 1876 application filed April 2i, 1876. l

To all whom 4it may concern:

Be it known that JAMES FARNAN, of Cleveland, in the county of Cuyahoga and State of Ohio, invented certain new and useful Im-v provements iu Hydrants; and I, MARY A. FARNAN, eXecutriX, do hereby declare 4that the following is a full and complete description of the same, reference being had to the accompanying drawings, making part of this specication, in which- Figure l is an outside view of the hydrant. Fig. 2 is a vertical section. The rest of the gures are detached sections.

Like letters refer to like parts in the different views.

The nature of this invention relates to a hydrant; and theobject of the same is to so construct and arrange 4said hydrant that the valve thereof shall be low down in the ground, out of the way of the frost, and which is operated from above by -a stem for raising Water, and which valve and other operative parts can be withdrawn from the .ground for repairs, &c., without digging up the hydrant.

`. A more complete description of the hy- ,drant and of its operation is as follows:

bush also assists in securing the connection of the tube G in section A, the bush being held rmly in place by the. spout H passing through theshell intothe bush, as will be seen in Fig. 2. In the section" B is fitted a thimble,`I, Fig. 2, in the lower end of which is cut athread, wherein is screwed the valve-head J attached to the end of the rod K. 10u each side -of the head is a valve, c a'. Of the valve a', the nut L is theseat, and the lower end of the tube M (inclosin g the rod) forms the seat ofthe valve a. A detached view of said tube M is shown in Fig. 4, in which it will be seen that the lower end is enlarged to such extent as to allow it to lit closely in the upper end of the thimble I, as shown in Fig. 2. Around the enlargement is cut a groove, N, Fig. 4, in which is made a small hole, c, the purpose of which will presently be shown.

The relation of the several parts of the hydrant in respect to each other will be understood on examination of Fig. 2. In said figureit will be seen that the stem or rod K of the valves c a passes up through the tube M and through the cap Gr, to the projecting end of whichis secured turnkey or handle O.

The practical operation of the above-described hydrant is as follows: The hydrant is set in the ground so deep as to reach the watermain or its branches, and beyond the reach of frost. lo the nutL is then attached the water-pipe leading from the main. The hydrant, as represented in Fig. 2, is such that whentherwater is shut off, in which event the valve c is screwed down upon the seat or nut 'L,. the water is prevented from passing up into the hydrant. To open the hydrant for the admission of water, the valve a is raised by screwing it up by turning the rod K by means of the handle O. This screwing up the valve will bring the valve a closeagainstA the end of the tube M, to prevent the water from passing upvinside thereof around the rod K. The valve a being open the water passes into the space e, around the thimble I, thence up through the tube U, between which and the outside of the tube M to the spout H. On shutting oft' the water, by screwing down again the valve c', the water left in the hydrant will escape therefrom through the hole c intothe groove N, around which it runs and.` lescapes toV the outside through the waste-pipe P in open relation therewith. The water nds its way up through this out-bore by passing down again into the space e about the thimble I; thence up the groove e cut in the side of the screw J 5 from thence between the tube M and the stern K to the hole c, opening into the groove N, from which it passes through the hollow lug P to the outlet P.V In this way all the water that may be left in the hydrant after closing the valve a. nds an immediate escape to the outside; hence in cold weather it cannot freeze in the hydrant and obstruct its workings.

This invention is an improvement on a hydrant for which Letters Patent were granted t0 JAMES FARNAN September 24, 187 2.

What is claimed as the invention of JAMES FARNAN, and desired to'be secured by Letl.. lhe vulve-head J ,I groove c', and valves aand a', in combination with the thimble I,

tubeM, :mdnut L, und section B, substantially 1 in the manner als described, and for the purpose set forth.

2. The combination ot' sections A B, tube or jacket O, nuts D and L, thimble I, wastepipe P, hollow lug P', and tube M, provided witli at groove, N, and hole c in the manner substantially as described, audfor the purpose specified. V
