HENRY JONES,l OEIHIL'ADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIM.- SELF, JAMES JONES, AND CHARLES HARRISON.
A Letters Patent No. 98,599, dated January 4, 1870.
The Schedule referred to in these Letters Patent and makingpaxt of the same.
To all 'whom it may concern Be .it known thatyI, HENRY JoNns, of Philadelphia, inthe State of Pennsylvania, have invented and made a new and. useful Improvement in Valves .for Water-Closets; and I do hereby declare the following to be afull, clear, and' exact description of the said invention, reference being had to the annexed drawing, making a part of this speoiication, wherein- Figure 1 is a vertical longitudinali section of the said improved valve or cock, and
Figure 2 isa sectional; the liife :t :c of fig. 1.
The same parts are referred to by similar letters.
This invention is for regulating the gradual closing of the valve supplying water to a water-closet, and for preventing concussion by the ram action of the valve in closing.
My invention consists in lan adjusting-cock, applied between the inlet-water chamber and an exhausting variable chamber, that regulates the closing of the valve, in combinationwith a valve having acylindrical plug, that gradually shuts off the water previous t0 the valve taking itsseat'.
a is the inlet-pipe, and b, the coupling, taking the pipe to the water-closet.
c is the barrel ofthe cock, formed with avalve-seat, d, between the pipes a and b.
The lower end of the barrel c forms the v ariable chamber e, ip which is a cup-leather piston, f, on a stem, g.
The piston f fits the interior of the chamber e closely, so that it becomes a guide, and relieves the cup-leather t of any strain or sidewiseaotion in moving the stem g, and in the edges of this piston f there are diagonal grooves, as seen in lig. 3, to allow water to pass through freely as the valve opens, and said diagonal slots prevent injury to the interior'of the chamber e, from the motion of the parts. p
Vh is the cap of the barrel c, through which the stem g passes, and is acted upon by the spring k, to causethe valve t to close. against the valve-seat d.
The valve'i is madewith a` leather-or elastic facefQ, and with a cylindrical hub, 3, that is of a size to iit into the smallest portion oi` the slightly-tapering opening in the seat d.' v
'--At the side of the barrel c is a projection containing the plug l, and 4 and I5 are water-ways Y between the variable chamber e and the water-space above the' piston f, s0 that the plug l forms a'cock to regulate the passage of water into the variable chamber c', as
the valve rises. This plug l may be formed with a screw-stem, through which the hole passes, instead of having a washerand ground barrel, as seen in tig. 2.
vIt is to be understood, that when the stem g-is ure of water against the valve frequently closes the same suddenly, producing a partial vacuum in the chamber' e, and causing a sudden concussion ora. series of them, by the ram action of the water. g
I prevent this by the cylinder 3, around the valve t', which cylinder, passiuginto the slightly conical opening in the valve-seat, cuts o", or nearly so,thepa s sage of the water, without any ram action, as the cutting olil of the water is gradual, as the valve i does not strike the seat until the variable chamber' is sufficieutly full to allow the necessary movement of the valve.
If the water-way 4 opened intothe pipe b, as has before been done, the pressure of the water upon' the cup-leather and piston f will act in the opposite direction to the spring k. Hence the closing of the valve is-not regular, but by the water-Way 4 opening int-o the supply-chanlher, there is nearly the same pressure upon each side of the piston f and cupleather, rendering the movement regular and reliable. What I claim,'and desire to secure by LettersPatent, isl 1. v'Il e cock or valve l, and water-ways 45, between -the variable chamber c and the supply-water chamber,
in combination with the piston j, valve i, and cylinder 3, as and for the purposes set forth.
2. The pistou f, formed with diagonal slots in its periphery, in combination with the cup-leather tand variable chamber e, 'as and for the purposes set forth. In witness whereof,-I have hereunto set my signa.- ture, this 11th day of November, A. D. 1869.

Giras. H.' SMITH, Guo. T. PINQXNEK is regulated by the cock 1,.
