FLOAT-CONTROLLED VALVE.

. and Improved Float-Controlled Valve, of

which the following is a full, clear, and exact description.

My invention relates to float controlled valves such as are suitable for use in connection with toilets, my more particular purpose being to provide an inlet valve which is sure in action as well as noiseless, and which presents a number of distinct advantages.

Reference is to be had to the accompanying drawing forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a cross section through a flushing tank equipped with my improved float controlled valve and adapted more particularly for household use; Fig. 2 is a detail showing, partly in elevation and partly broken away, the mechanism 01": the inlet valve, the Valve being now closed; 'Fig. 3 is a view somewhat similar to Fig. 2, but showing the parts in a difi'erent position, the inlet valve being now open; Fig. 1 is a fragmentary plan view of the mechanism shown in Figs. 2 and 3; and Fig. 5 shows certain interdependent parts of the inlet valve, these parts being assembled and occupying their respective relative positions but not as yet being connected together- A flushing tank is shown at 6. Mounted within the flushing tank is an outlet valve 7 Connected with this outlet valve for-the purpose of actuating it is a rod 8 which is connected with one end of a lever 9. A. chain 10 is connected with the opposite end of this lever and is operated by hand for the purpose of tilting the lever and thus controlling the outlet valve 7. The lever 9 is mounted upon a pivot 11, the latter being supported'by' a bracket 12.

Extending upwardly into the flushing tank 6 is an inlet pipe 13, and supported by this inlet pipe'is a nozzle lithrough which water is admitted into the-flushing tank at intervals. Mounted upon the upper end of the inlet pipe 13 is a valve casing 15, the construction of which can best be understood from Figs. 2 and 3. A threaded sleeve 16 is fitted into the bottom of the cas- Specification of Letters Patent.

ing 15 and is concentric to the same. The sleeve 16 carries a collar 17 integral with it and also carries a smooth portion 18 of annular form, the portion fitting neatly upon the upper end of the inlet pipe 13. The sleeve 16 is further provided with an annular bead 19 integral with it and constituting a valve seat.

The casing 15 is provided with a neck 20 extending upwardly from it and having its upper edge slightly rounded internally.

The neck 20 is provided with slots 21 in registry with each other. A flat core 22 is disposed within the neck 20 and carries two enlarged disk- like portions 23 and 24. These disk- like portions 23, 24, fitting neatly into the neck 20, serve as guides for centering the core 22 and for maintaining the same in proper working position. The core 22 is provided with a hole 25, the diameter of this hole being greater at its ends than at its middle, as will be understood from Fig. 2. Adjacent to the slot 21 and in registry therewith is an eye 26. Extending through this eye and through the hole 25 is a pin 27 which is provided with an annular bead 28 and with a ball '29, the annular bead being adapted to fit against the core 22 and the ball 29 being located outside of the neck 20.

The core 22 is provided with a reduced cylindrical portion 22 and encircling the latter is an annular collar 30, the upper surface of which is rounded. Fitting upon this collar is an annular washer 31 of leather. This washer fits around the portion 22 of the core. The collar 30 carries an annular bead 32 integral wit-h it, and disposed within this bead isa packing 33 of rubber, leather, or similar material. 'A screw 33 extends through the packing 33 and into the lower end of the reduced cylindrical portion 22. The collar 30 and washer 31 being smooth are simply slipped over, or fitted around, the reduced portion 22 and when the packing 33 is secured in position by aid of the screw 33 the collar 30 and its washer 31 are held securely in position. The washer 31 curves over the collar 30 in such manner as to allow the valve, when repackingis needed, to be easily removed from and replaced within the rounded end of the neck 20. hen water enters the Valve casing, the leather washer opens upwardly and prevents the water from splashing out of the slots and the neck of the valve casing. While the the core.

Washer is purposely made of leather, it may be made of any flexible material suitable for the purpose.

An arm is shown at 34: and is provided with an enlarged end 35, the latter being made hollow and fitting loosely over the ball 29. The arm 3% carries a sleeve 36 integral with it, and extending radially into this sleeve is a thumb screw 37. A rod 38 bent substantially into L-shape extends throughthe sleeve 36, and is, by aid of the thumb screw 37, adjusted relatively to this sleeve. The arm 34: is journaled upon a wing bolt 39, and the rod 38 carries at its outer'or free end a ball float 40. By loosening the thumb screw 37 and moving the rod 38 bodily upwardor downward, and then tightening the screw 37, the-float may be, within reasonable limits, adjusted relatively to the arm 34, this adjustment serving to control the sensitiveness of the valve rela tively to the upper level reached by the water in the tank when the inlet valve closes.

In order to form the washer 31, I merely cut out a thin ring 31 of leather and form this ring to fit the top of the collar 30. After doing this I secure the collar 30 and the washer 31 upon the reduced portion 22 of Owing to the fact that the collar 30 and the washer 31 are not rigidly secured to the reduced portion 22, the collar 30 has an infinitesimal movement, or at least a slight looseness which enables it to adjust itself relatively to the valve seat 19. Then by aid of the packing 33 the collar 30 has no trouble in making a neat water-tight fit relatively to the valve seat.

It will be noted that whenever the ball float 40 is raised, the arm 34: is rocked upon the bolt 39 as a center and that it forces the ball 29 downwardly so that the pin 27, serving as a lever, forces the packing 33 down against the valve seat 19.

The arm 34 and pin 27 fitting together as above described, constitute a very eflective joint, and, moreover, the connection between the arm and pin is a universal ball joint especially suited for high pressure tanks.

When the parts are in normal position as indicated in Fig. 2, the eye 26, the pin 27, the ball 29, and the longitudinal axis of the arm 34, and the axis of the bolt 39, are all in alinement with each other. By this arrangement the parts are rendered not only sensitive, but also positive in action. If, for instance, the pin 27 happens to be turned slightly, this is a matter of no consequence, as the tilting of the arm 34 into the position indicated in Fig. 3 will necessarily raise the ball 29 and this in turn will lift the valve off its seat. The parts are bound to center themselves when the valve is again closed.

At 41 in Fig. 1 is shown a quantity of water filling the tank 6.

The operation of my device is as follows:

The parts being made and put together as above described, and the movable parts being brought into position as indicated in Fig. 1, the device is ready for use. The chain 10 being pulled down by the operator, actuates the outlet valve 7 so that most of the water in the tank is discharged in the manner well known in this art. The chain 10 being released, the lever 9 rocksto nor mal position. The exit of the waterfrom the tank 6 causes the fioattO to descend so that the movable parts appear as indicated in Fig. 3. The inlet valve is now open; that is to say, the packing 33 is raised from the seat 19. Water, under pressure, (which may be very high) now flows upwardly from the inlet pipe 13 into the casing 15 and downwardly through the nozzle 14, being discharged into the tank 6, as shown at 41.

34 rocks upon the bolt 39 as a center and 'in so doing draws down'the ball 29 and the adjacent end of the pin 27. This forces the packing 33 downwardly against the valve seat 19. This closes the valve and prevents further ingress of water.

It will be noted that the movable parts shown in Fig. 2 are so thoroughly self-acb' just-ing thatthe closure of the inlet valve is rendered positive and is not attended with any singing or vibratory noise, or by any water hammering.
