WATER-SUPPLY AND DRAINAGE APPARATUS.

Application filed February 7,

To o/,ZZ whom it may concern.-

Be it known that we, PETER MARTIN NE- vrUs and WILLIAM EDWARD BARTON, citizens of the United States, residing at Seattle, in the county of King and State of Washington, have invented. certain new and useful lmprovements in Water-Supplyl and Drainage Apparatus, of which the following is a specification. l

` Our invention Irelates to combined water supply and drainage apparatus particularly adapted for use with water closets and similar devices, and has for its object to provide certain improvements in the construction of the same as will be hereinafter more definitely pointed out and claimed, reference being had to the accompanying drawing, in which:

Figure 1 is a central vertical sectional view of our improved apparatus, the same being shown in position to admit the flow of water therethrough to the closet or tank. Fig. 2 is a similar view, showing the valves arranged to drain the piping.

Similar numerals of reference denote corresponding parts in the two views.

In the said drawing the reference numeral 1 denotes a chamber located partly or wholly below the surface of the ground, and having tapped thereinto near its bottoina water supply pipe 2. Also tapped into said chamber above said water supply pipe 2 is a drain pipe 3 connected to the sewer, while intermediate said supply and' drain pipes there is tapped into said chamber a discharge pipe 4 leading to the point of supply, shown in this instance as a tank 5.

Fixed to the cap piece 6 of the chamber 1, and depending into said chamber, is a pipe or tube 7, attached at its lower end to a fitting 8 embodying a valve seat 9, and carrying a suitable packing or washer 10 closely fitting the interior of chamber 1', said packing, when said tube 7 is in position, lying between the openings of pipes 3 and 4 into chamber 1. Also fixed in and depending from said fitting 8 is a pipe o r tube 11 of equal diameter with pipe or tube 7, and forming a continuation' thereof, said pipe or tube 1 1 being fixed at its lower end in a tting 12, embodying a valve seat 13, and carrying a suitable packing or washer 14 similar to packing or washer 10, said fitting and its parts lying between the openings of pipes 2 and 4 into chamber 1.

Specification of Letters Patent.

Patented April 23, 1907'.

1906. semina. 2'9a922.

Located within and vertically movable in said pipe or tube 7 is a valve stem 15, carrying the upwardly opening valve 16 adapted to seat in valve seat 9, and the downwardly opening valve 17 adapted to seat upwardly against valve seat 13. Said valve stem 15- is projected through the cap 18, closing the pipe or tube 7, and is shown in position to be depressed by the water closet seat 19.

From the above description the operation of our improved construction will be understood to be as follows: With the closet seat depressed when in use, the stem 15 will be forced downward to the position shown in Fig. 1, thus seating valve 16 and opening or unseating valve 17, the result being that the water supply under the pressure of the main entering through pipe 2 will pass through valve seat 13 into pipe or tube 11, and from thence through apertures 20 in said pipe or tube 11 into that part of the chamber 1 lying between washers 10 and 14, from whence it will pass through pipe 4 into the tank 5 ready for use. Now, when the pressure on the seat 19 is removed, the pressure of the water exerted against the under side of valve 17 as well as against the under side of valve 16, will at once force said valves and the valve stem 15 upward, thus closing valve seat 13 and opening valve seat 9. The water in pipe 4, being thus relieved from upward pressure, will at once drain back into that part of chamber 1 lying between washers `10 and 14, and from thence through apertures 20 into pipev or tube 11, thence upwardly through valve seat 9 into pipe or tube 7, from which it will pass through apertures 21 into the chamber 1 above washer 10, from whence it will be carried off by drain pipe 3, as clearly seen in Fig. 2.

While, for convenience of manufacture, we have shown two pipes or tubes 7 and 1.1

united by the fitting 8 having therein the valve seat 9, it will be understood that said pipes or tubes may be formed in one piece, provided with the interior valve seat 9, and having the fitting 8 and its packing 10 fixed to the exterior thereof.

The main vadvantages of our improvedl construction are, first, that the pipe 4 above the ground and up to the tank 5, where it is exposed to frost, is automatically drained after each use of the closet and remains so drained until said closet is again used, when.

IOO

it will again be automatically supplied with water; secondly, by employing the chamber 1 of even diameter throughout the valves, valve seats and their parts may be readily withdrawn therefrom by unscrewing cap 6 and withdrawing pipe or tube 7, the same carrying with it the whole apparatus, including the valves and valve stem 15, whereby repairs thereto may be readily made, and, thirdly, the operation is automatic and without the employment of springs for closing the valves, the weight of the user of the seat 19 admitting the water to pipe 4,and the pressure of the water from supply pipe 2 cutting oli the water and permitting pipe 4 to drain.

While our device is particularly applicable for use with water closets, we do not wish to be understood as limiting its application to the same, as it may be equally well employed with other water supply devices, such, for instance, as roof tanks and the like, wherein the automatic draining of the pipe 4 to prevent 'freezing is a desideratum.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In a water supply and drainage apparatus, a chamber having free communication, respectively, with water supply, discharge, and drainage pipes, a tube located in said chamber and apertured coincident with the discharge and drainage pipes, means intermediate said tube and chamber for dividing the latter into sections corresponding with the supply, discharge, and drainage pipes, conjointly operating valves in said tube normally operated bythe water pressure from the supply to close communication between the supply and discharge pipes and to open communication between the discharge and drainage pipes, and means for reversing the position of said valve.

2. In a water supply and drainage apparatus, a chamber of even diameter having free communication, respectively, with water supply, discharge, and drainage pipes', a tube removably located in said chamber and apertured coincident with the discharge and f drainage pipes, means carried by said tube for dividing said chamber into sections corresponding with the supply, discharge and drainage pipes, a-valve stem carried by and movable in said tube and projecting therev from in position to be operated, and valves l close communication between the supply and discharge pipes and to open communication between the discharge and drainage pipes,

said valve stem affording means for reversing z the position of said valves.

3. A water supply and drainage apparatus, embodying a chamber, a water supply pipe leading into said chamber, a drainage pipe leading from said chamber, a discharge pipe connected with said chamber intermediate said supply and drainage pipes, a tube located in said chamber, means carried by said tube for separating said chamber into sections corresponding with the supply, discharge, and drainage pipes, said tube communicating with said sections coincident with the discharge and drainage pipes, a valve stem movable in said tube, and valves carried by said stem for simultaneously opening communication between the water supply and discharge pipes and closing coinmunication between the drainage and discharge pipes, and vice versa.

4. A water supply and drainage apparatus, embodying a chamber oi' even diameter, `a water supply pipe leading into said chamber, a drainage pipe leading from said chamber, a discharge pipe connected with said chamber intermediate said supply and drainage pipes, a tube removably located in said chamber, packings or washers carried by said tube for separating said chamber into sections corresponding with the supply, discharge, and drainage pipes, said tube being perforated to communicate with said sections coincident with the discharge and drainage pipes, a valve stem carried by and movable in said tube, and valves carried by said stem for simultaneously opening communication between the water supply and discharge pipes and closing communication between the drainage and discharge pipes, and vice versa.

In testimony whereof,we have hereunto set our hands in the presence of two subscribing witnesses.
