Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed September 17. 1904. Serial No. 224,815.

To all whmn it puny concern:

Be it known that I, JOSEPH O. MoCARL, a citizen of the United States, residing at WVeston, in the county of Lewis and State of I/Vest Virginia, have invented new and useful Improvements in Automatic Valves for I/Vater- Closets, of which the following is a specification.

This invention relates to automatic valves for water-closets.

The objects of the invention are to improve and simplify the construction of such valves; furthermore, to increase their efficiency in operation.

- I further object of the invention is to improve the general construction of the closet.

I/Vith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of constructionhereinafter described and claimed as a practical embodiment thereof.

In the accompanying drawings, forming a part of this specification, Figure 1 is a vertical section of an apparatus constructed in accordance with the invention. Fig. 2 is a similar section of the valve. Fig. 3 is a detail perspective view of a break-jointused in connection with the device, the parts thereof being separated for the purpose of illustration.

Like reference characters indicate corresponding parts in the different views.

The reference-letter A indicates the bowl; B, the flushing-tank; O, the valve, and D the depressible seat, which is hinged or pivotally connected to the bowl in any suitable manner.

The valve 0, as shown in Fig. 2, comprises an inlet-chamber 1, which is provided with a removable cap 2, with which connects an inlet-pipe 3, leading from a water-main or other suitable source of supply. The cap 2 is pro vided with a depending tubular sleeve 4, which forms the upper bearing for a hollow valve-stem 5, on which is mounted an inletvalve 6, which controls the passage of water from the inlet-chamber 1 to the valve-chamber 7, said valve-chamber 7 communicating, by means of the pipesection 8, with the flushing-tank B. Disposed in the upper portion of the flushing-tank B is an air-outlet valve 9 formed with a plurality of air-outlet perforations 10, said air-outlet perforations being adapted to be closed by the rising movement of a float-valve 11, having a stem 12, formed with a conically-enlarged upper end 13. The valve 9 permits the escape of an from the tank as it fills with water, and by closing said air-outlet perforations when the tankis completely filled with water said valve automatically prevents the escape of water.

Mounted upon the tubular valve-stem 5, below the valve-chamber 7, is an outlet-valve 14, which controls the outlet from the valvechamber and flushing-tank, said valve controlling the opening between the valve-chamber 7 and the outlet-chamber 15, which communicates, by means of a pipe-section 16, with the bowlA. The passage] 7 through the hollow valve-stem 5 terminates in an outlet 18 below the outlet-valve 14, said passage thus serving to deliver a small and constant supply of water from the inlet-chamber 1 to the outlet-chamber 15, and thus to the bowl.

A- cap 19 is screwed or otherwise suitably secured in the lower end of the outlet-chamber 15 and serves as the lower bearing for the valve-stem, said cap being provided with an auxiliary cap 20, which acts as a stuffing-box for the valve-stem 5.

At its lower end the valve-stem 5 is pivotally connected with an operating-lever 21, which is pivoted or fulcrumed upon a support 22. The operating-lever 21 is connected with the depressible seat D by means of a drawrod 23, which is formed with a breakjoint 24, the upper member of the draw-rod being formed with a downwardly-projecting tongue 25, which bears against the lower member of the draw-rod, and thus prevents the break-joint from straightening out, for which reason said break-joint is adapted to bend easily when the depressible seat is raised into vertical position.

Connected with the free end of the operating-lever 21 is a foot or treadle lever 26,

which is pivoted to a suitable support 27.

The portion 28 of the treadle-lever 26 is adapted to be depressed by the foot of a person using the device. In order that the treadle-lever 26 wlll not prevent the upward movement of the operating-lever 21 when the seat D is depressed, a slot 29 is formed in said treadle-lever 26 at the point of its conting the tank to be filled.

nection with said operating-lever 21. The operating-lever 21 is eld normally in lowered position by any suitable automatic meanssuch, for instance, as a weight 30, which is attached thereto.

If it be not desired to employ a hollow valve-stem for supplying a continuous stream of water to the bowl, a small supply-pipeis connected with the opening 00 in the outletchamber 15 for this purpose.

Constructed as above described, the operation of the improved device is as follows: It will be understood that the weight 30 normally holds the operating-lever 21 in lowered position, so that the inlet-valve 6 is closed, the outlet-valve 14 is opened, the seat D is raised slightly, as shown in Fig. 1, and a small but constant stream of water is permitted to flow from the supply-pipe 3 and inletchamber 1 to the outlet-chamber 15 and bowl A through the passage 17 in the valve-stem 5. When the seat D is depressed upon the bowl, the upward movement on the drawrod 23 causes the operating-lever 21 to be raised, thus simultaneously closing the outlet-valve 14 and opening the inletvalve 6. For this reason during the period of time in which the seat is depressed the flushing-tank is filled with water from the supply-pipe 3 and inlet-chamber 1. As soon as the tank becomes filled the float 11 rises, thus preventing the escape of water therefrom and auto- -matically shutting off the supply of water thereto. When pressure upon the seat D is relieved, the weight 30 causes said seat to rise slightly, thus permitting the operatinglever 21 to descend and open the outlet-valve 14, at the same time closing the inlet-valve 6. The opening of the outlet-valve 14 permits the water which has collected in the tank to flow through the pipe 8, valve-chamber 7, outlet-chamber 15, and pipe 16 into the bowl A. When the device is used by a man, the seat D is raised into vertical position and the treadle-lever 26 is depressed with the foot, thus elevating the operating-lever 21, closing the outlet-valve 14, and opening the inletvalve 6, as previously described, and permit- It will be observed that the break-joint in the draw-rod 23 permits the seat D to be raised into vertical position without interfering with the operation of the lever 21 by the treadle-lever 26.

From the foregoing description it will be apparent that the tank is normally empty and is filled only during the use of the device.

Changes in the precise embodiment of invention illustrated and described may be made within the scope of the following claims without departing from the spirit of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is 1. In a device of the character specified, the combination of a closed tank, an inletvalve thereto, an outlet-valve therefrom, a stem for said inlet and outlet valves, an operating-lever connected with said stem, a bowl, a movable seat thereon, a draw-rod having a breakjoint, connecting said movable seat with said operatinglever, a treadlelever having a slotted connection with said operating-lever, and an air-outlet valve in said tank, adapted to be closed automatically when the tank is filled.

2. In a device of the character specified, the combination of an inlet-chamber, a valvechamber, an outlet-chamber, a tank connected with the valve-chamber, an air-outlet valve in said tank adapted to be closed automatically when the tank is filled, an inletvalve between said inlet-chamber and valvesage leading from said outlet-chamber to said bowl, an operating-lever connected with said valve-stem, a movable seat, a draw-rod connecting said seat with said operating-lever and having a break-j oint therein, a foot-lever having a slotted connection with said operat ing-lever, and a weight attached to said operating-lever.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH C. MoCARL.
