TANKVALVE.

Specification of Letters Patent. Application led April 19, 1909. Serial No. 490,901.

Patented Dec. 2,1,

` ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention has for its object to provide an improved float controlled valve for flushing tanks, and to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The invention is illustrated in the single view of the drawing, which View is chiefly in vertical section but partly in side elevation, and with some parts broken away.

The flushing tankis indicated by the numeral 1. Through the bottom of this tank,

an intake sleeve 2 having a flanged upper end,and a threaded lower end is passed ver-- tically. .On the threaded lower end of the sleeve 2 is a flanged nut 3 that clamps the head of said sleeve tightly against the bot' tom of the tank 1, and forms a water-tight joint therewith. Opening through the lower end of the sleeve 2 is a small sleeve 4, per end-of which is' closed, but is provided near its upper end with one or more lateral openings 5;

An upright tubular valve casing 6 is threaded at its lower end into a seat formed therefor in the head of the intake sleeve 2.

At its intermediate portion, this tubular valve casing 6 is provided with a lateral discharge pipe 7, shown as provided with a downturned discharge port 8, and with an upwardly extended after-wash pipe 9. Seated in the head of the intake pipe 2 and extending concentrically upwardly into the lower portion of the tubular casing 6, is an externally threaded tube- 10, which, as shown, is also extended through a gasket or annular washer 11 pressed between the lower end of 'the valve casing 6, and the bottom of the seat formed therefor in the head of the intake sleeve 2; The valve seat proper is formed by a pliable tube`12 preferably of rubber or composition of rubber and binding fabric. Preferably the said valve --seattlie up- 12 is, made from a section of small reinforced rubber hose, the external diameter of which is such that it fits snugly within the lower portion of the tubular casing 6, and the internal diameter of which is such that it may be screwed firmly onto the threaded exterior of the small metal tube 10.

The upper end of the pliable tubular valve seat 12 terminates below the discharge pipe 7, but extends very considerably above the upper extremity ofthe tube 10.

Mounted for vertical movements in the upper portion of the valve casing 6, is a plunger valve 13, the head 14 of which is conical or tapered, and is adapted whenA moved downward from its open position, shown in the drawing, to tightly engage and close the upper end of the said tubular valve seat 12. The said tubular valve seat being pliable, will adapt itself to the form of the valve head 14, regardless of whether or not the latter is perfectly true or is slightly worn, and will yield sufficiently toz'insure a perfectly water-tight joint. The valve head 14 is shown as provided with a collar i5 which serves as a centering guide there- The upper-end of the stem portion 13 of the intake valve has a seat 1G 'that receives the headed end 17 of an operating lever 18, which latter is interinediately pivoted to a lug 19 on the upper end of the valve casing (3, and at its free end is provided with the usual float inthe form of a hollow air bulb 20.

The operation of this improved valve mechanism is as follows: The water which is delivered from a suitable source of supply under pressure' is delivered into the inlet tube 4 and from thence is discharged radially through the port orports 5 into the intake sleeve 2, and thus is not allowed to shoot directly upward through the tube 10. This also prevents chattering of the valve. fhen the water in the tank falls below a predetermined point, the float 20 will force the valve 13-14 into an open position, and the water will then run through the valve casing 6 and will be discharged into the tank the float 20 Will close the valve 13-14 and stop the further How of water into the tank through the valve seat l2. I

This improved valve mechanism, while of simple construction and comparatively small cost, has in practice been found highly etlicient for the purposes had in View. The

liable tubular valve seat Will Wear for a ong time, and when worn out may be replaced at small cost. Furthermore, when one end thereof is worn, it may be reversed end for end and then used until the other end is worn out.

What I claim is:

l. In a valve mechanism, the combination with a tubular valve casing, having an internal axially located tube, of a tubular valve seat in said-valve casing telescoped-around said internal tube, and a valve mounted in said casing for reciprocating movements, and provided with a pointed end engageable with one end of said tubular valve, substantially as described.

2. A valve mechanism comprising a tubular valve casing having a rigidly secured internal externally threaded tube, of a pliable tubular valve seat in said casing placed around the threaded exterior'of said threaded tube, and a float controlled valve mounted for endwise movements in said casing, and provided With a pointed end insertible into the adjacent end of said pliable tubular valve seat, substantially as described.

3. In avalve mechanism, the combination With an intake sleeve having in its lower end, ank intake tube with a lateral discharge passage, of a tubular valve casing connected to the upper portion of said sleeve, a v`alve seat in said casing, said casing having a lateral discharge orifice, and a float actuated plunger-like valve mounted in the upper portion of said casing and provided with a pointed end engageable With the adjacent upper end of said valve seat, substantially as described.

4. The combination with a tank, of an intake sleeve extending through the bottom thereof, a tubular valve casing connected at its lower end to the upper end of said intake sleeve, said casing having a lateral discharge orifice, of a metal tube axially secured Within said valve casing, a pliable tubular valve seat surrounding the upper end portion of said internal tube and fitting the interior of said casing, and a float actuated plungerlike valve seated in the upper portion of said casing, and provided with a pointed lower n end engageable with the upper end of said pliable tubular valve seat, substantially as described.

.5. The combination with a tank, of an intake sleeve having in its lower end, an intake tube with a lateral discharge passage within said sleeve, of aA valve casing connected to the upper portion of said sleeve, a valve seated in said casing, said casing having a discharge orifice, and a float actuated valve for opening and closing the passage through said casing, substantially as described.

6. In a valve mechanism, the combination with a valve casing, of an endwise reversible cylindrical valve seat, constructed at least in part of rubber and having flexible ends, deltachably mounted in said casing, and a plungerslike valve having a pointed or tapered end for engagement with one of the flexible ends of said cylindrical valve seat, substantially as described.

In testimony whereof I afx my signature in presence of two Witnesses.
