Specification forming part of Leilers'Patent `i\l,0.f{1;5,2l3,` dated May 13, 186.

To aZZ whom) it may concenn: o'

BeA it 'known that I, SILAs H, BROWN, of Troy, in the county of Rensselaer and State of New York, have made certain new and useful" Improvements in I-Iydrants; and I 1.hereby.declare that the following isafdescription ofV the saine in terms which I now think "sutciently full, clear,v and exact, reference being; had to the annexed drawings, making a part of this specification, in which--` Figure l is a front view; Fig. 2, a vertical section in the line a: a.' of Fig. l or line y y of the front face of the slide-valve, whereby the leakage from the .iischarge-pipe is accommodated, and, fourth, in the method .of opening 'and closing the valves, so that they cannot b operated independen tlyo'f the operating-lever. j To enable others skilled in the art to make and use my invent-ion, I will proceed to de- Iscribe its construct-ion and operation,

Connected with the supply-pipe A is a 'valve-box, B, in which 1 arrange apuppet valve, a, whose stein b extends upwardly 'and is surrounded with guide-wings c. ,It is held up onto its seat bythe joint action ot" the pressure of the fluid and the coiled spring' d, and when in that position its stein b projects a short distance into the valve-box (l, which siirinounts the val ve-box ll. W ith in the valverbox C, I also place the slide-valve l), which has upon its lower end areal-ward projection or toe, e', and upon its front face a groove, s, corresponding;` with the portfin the discharge- ,pipe F, from which proceeds the groove t. The

valve-stem E projects t-h rough a slot l-l, formed through the cap l of the valve-box t, and isreeeived within a hole inade through the lower end of the yoke or val ve-rod K, where itis. retained and the sliding;l valve. l) pressed upon its seat by means of the `pin h and coiled springt. The valve-rod--K has a mortise cutthroughgt atj vof., a sufeient length, the

discharge-pipe F projecting through it, to allow of the requisite motionito open and close the valves, and ext-ends upwardly into a hole, k, in the cap I), which-'serve as guides tokeep thevalve-rod K in its vertical posit-ion. The cap L is formed in three sect-ions, between the two lower, Z andm, of which -are formed the double-inclined slots or planes -n o, in which works the double-armed operating-lever M, l

secured to the valve-rod K'by-the` collars. p and 'v'.

,The operation of my hydrant., which may be applied also to, the drawing' of allliquids as well as to steam-engines, .is as follows: Suppose the fluid t-ohe'shut'otl. The puppetvalve a rests upon Aits seat, andthe sliding valve D covers its port f, as represented in 'red lines. N ow by moving'v the double-armed lever M to the. lett the inclined pla-nes nv and o force down the valve-rod h',- carrying with it the sliding valve l) and the' puppet-valve a, the projection or toe e coming in contact.

with the head of the stein b. In this position both valves are open and the fluid has an uninterrupted How. 0n reversing,r the action of the lever M the slidingvalve D is elevated over its port j, and the pressure' of the water and the coiled spring d raise the puppet-valve a to its seat, and the flow is cntoii". V

By thus arrangingtufu valves and operatl,ing them in the manner described Ifl ain 'enabled still to use my hydrant although one of l the valves becomes injured. tir-inoperative. ln the construetionand arrangement'-of my sliding valve D, andv in operatingjitfhy means of its stemproject-ing through the slot Il in the cap lof the valve-box (j and through the hele in the lower end of the valve-rod li, l am enabled to do without startling-boxes, which are always liable to `trol. out ol order.

'lhe grooves on the front face ol' the valve I) are another fea-turc ol importance when the hydrant is used in the yard or street,

where the valve-.stein E and its connections are below'the ground und out of the way of the frost, for by these the waste water in the discharge-pipe F, which is above the ground andmsubject to the frost, passes freely off through the slot li andthe niortise j, and, finally, hy operating," the valves by means of the double-armed lever M and inclined slots or planes l/zfand o, T'secure a regular and st'i'llwil,

The4 sliding' valve D., with its ntljnnt'fts K, E,- nn't'l i', whm'elw itninl thil valve umay -bif olmrntoil without the vuse of shitting-hoyos.,
