Patented Sept. 8, 1936 UNITED STATES PATENT @FFEQE FLOOR VALVE William E. Sloan, Chicago, llll.

Application July 13, 1934, Serial No. 736.,898 Claims. (011. 137 -93) This invention relates to floor valves and has for its object to provide a new and improved device of this description. The invention has as a further object to provide a floor valve for sup- 5 plying water to fixtures and which may be easily and quickly operated by the foot. The invention has as a further object to provide such a floor valve which may be easily and quickly adjusted without shutting off the supply. The invention has other objects which are more particularly pointed out in the accompanying description.

Referring now to the drawing, Fig. l is a view of one form of floor valve embodying the inven- 5 tion with parts broken away showing the temporary cover thereon which is used during the building operations;

Fig. 2 is a sectional view through the valve illustrated in Fig. 1 showing the floor cover removed and the push button in position;

Fig. 3 is a plan view of the temporary cover of Fig. 1.

Like numerals refer to like parts throughout the several figures.

Referring now to the drawing, I have illustrated a floor valve having a casing I which is located below the upper surface of the floor. This casing has an inlet 2 and an outlet 3. The inlet 2 is connected with the water supply and the outlet 3 is connected with the fixture in connection with which the water is used, such for example as a urinal, closet bowl or any other suitable fixture.

Within the casing l is a main valve 4. This main valve is shown as a piston valve and has the seating member 5 which seats on the seat 6 surrounding the opening I by means of which the inlet 2 is connected with the outlet 3. The main valve 4 is provided with a bypass passageway 8,

the end 9 of which communicates with the chamber iii in connection with the source of supply through the inlet 2.

In the portion 8 of the bypass, which is enlarged, is a bypass controller II. The bypass 8 connects the chamber III with the chamber l2 above the main valve 4. The bypass controller normally rests on a seat l3 and is arranged with a groove l4 so that only a small amount of water passes therethrough when the bypass controller is seated, as shown in Fig. 2.

Located above the main valve 4 is an auxiliary valve l5 which seats on a seat IS, the auxiliary valve controlling the opening I! which connects the chamber I2 with the chamber l8. This chamber 18 is connected with the outlet 3 by the passageway l9. The auxiliary valve i5 is .connected with a member 28 which has a screw threaded portion 2! which engages an internal thread 22 in the casing i. The member 20 has an annulus 23 which engages an engaging member 5' 24, engaging a shoulder 25 on the casing. The member 20 also has an annulus 26 which engages the packing member 21, engaging a shoulder 28 on the casing.

The auxiliary valve I5 is provided with a stem 10 29 which passes through an opening in the member 20, there being a packing gland throughwhich it passes, consisting of the threaded member 30 and the packing member 3!. A spring 32 surrounds the valve stem 29 and engages the pack- 15 ing member 3! at one end and a stop 33 onthe valve stem at the other end. The valve stem 29 is provided with means for engaging it with a tool to turn it, and l. have shownthe groove 34 for the blade of a screw driver. 20

Removably connected with the top of the casing l is a. floor member 35 which has a downwardly projecting part 36 having a threaded connection with the casing I. Within the floor member 35 is a push button 31 which is located with- 25 in a holding member 38. This push button is hollow and contains a valve stem engaging member 39 which is adjustably mounted in the push button and which engages the top of the valve stem. The valve stem engaging member l8 has a 3 stop 40 and the push button has a cooperating stop member 4|. These members prevent the upward removal of the push button.

The valve stem 29- has a screw threaded opening at its lower end. and there is a screw thread 35 ed stop member 42 therein which projects therefrom. There is an engaging part 43 associated therewith which engages some part on the main valve 4 when the main valve is lifted so as to limit the upward movement of this main valve. 40

Means are-provided for preventing the member 42 from rotating. As herein shown there is connected to this member a piece 44 which has a pin 45 sliding in an opening 46 in the member 20. When the device is installed the casing HS 45 sunk into the floor before the floor is completed. and a cover plate 41 is placed over the top thereof, the cover plate having a downwardly projecting screw threaded part 48 which engages internal screw threads in the casing, as shown in Fig. 1. 50 This plate has a groove 49 for a tool so that it may be rotated into place and in position, or remove it. The casing I of the valve is generally placed in position before the floor is completed and the threaded part 48 of the cover plate 41 is of suillcient length so that the cover plate may be adjusted to bring its upper surface to the upper surface of the finished fioor. After the floor is completed this cover plate is removed and the parts shown in Fig. 2 inserted in position. The downwardly projecting part 36 of the floor member 35 is of sufficient length to permit the adjustment of the floor member to bring its upper face flush with the upper face of the floor. This adjustment is necessary because it is not practicable to have the casing of the valve properly located with relation to the upper surface of the floor. This adjustment, however, makes this wholly unnecessary, as the floor member can be adjusted to bring it to the proper position. The stem engaging member 39 of the push button can then be properly adjusted with relation to the valve stem 29 by moving it downwardly when it is necessary to move the floor member 35 upwardly, and by moving it upwardly when it is necessary to move the floor member downwardly. It will be seen that by means of this construction the parts may be easily and quickly adjusted to bring them into proper relation to the upper face of the floor and to the other parts of the valve.

In the use of the device the floor member and push button are adjusted to the proper position and the party using it presses with his foot upon the push button 31. This moves the auxiliary valve stem 29 and opens the auxiliary valve l5. Water then escapes from the chamber I2 up through the auxiliary valve into the chamber l8 and down through the passageway l9. This reduces the pressurein the chamber l2 and the pressure in the chamber I0 lifts the main valve to open it and permit the water to pass from the inlet 2 through the valve to the point of use. The user then removes his foot from the push button and the spring closes the auxiliary valve. The main valve rises until its movement is stopped by the engaging face 43. Water then passes up through the bypass into the chamber I2, causing the main valve to be.seated. During the initial upward movement of the main valve 4 the bypass controller I I is moved upwardly. As the main valve approaches the upward limit of its stroke the part 43 engages the end of the bypass controller II and moves it downwardly so that the water can easily pass up through the bypass into the chamber H. The pressure in the chamber I2 and in chamber I0 is then substantially equalized and the bypass controller ll drops down on its seat l3. The groove l4 then permits a small amount of water to pass through the bypass and permits the main valve to slowly move down to its seating position. The amount of water passing through the valve may be regulated without shutting off the water by simply removing the push button and push button holding member and by means of a tool inserted in the groove 34 of the valve stem, rotating such valve stem to vary the position of the engaging face 43. The rotation of the valve stem causes the member 42 to move up or down without altering the position of the auxiliary valve.

If it is desired to lessen the amount of water passing through the valve, the engaging face 43 is moved toward the main valve, and if it is desired to increase the amount it is moved away from the valve. After the adjustment has been made the push button may be again inserted in position.

A floor valve comprising a casing, a main valve therein dividing the casing into two chambers, a bypass connecting said chambers, an auxiliary valve above the main valve, a stem therefor, a stop device adjustably connected with said stem and adapted to be moved toward or from said main valve to vary its upward movement, a controlling member for the stem connected with the valve casing and in proximity to the floor level, and means for adjusting said stop device without shutting off the water.
