WATER-CLOSET.

Specication of Letters Patent.

Patented Aug. 4, 1914.

Application led August 3, 1908. Serial No. 446,503.

T0 all whom it may concern Be it known that I, EARL G. WA'rRoUs, a citizen of the United States, residing at Chicago, in the State of Illinois, have invented a certain new and useful Improvement in later-Closets, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to what are known as seat-actuated closed-tank closets, being closets in which the depression of the seat opens a valve which admits the 'water supply to a closed tank, which fills with water while the seat is depressed, and then discharges into the closet when the pressure on the seat is removed.

It has for its principal object an improved construction, arrangement and operation of the valves which control the admission of the water supply to the closed tank and its subsequent release and discharge therefrom.

In the accompanying drawings Figure l is a middle vertical section of the rear portion of the closet and the valve casing and the valves supported thereon; Fig. 2 a top plan view of the parts shown in Fig. 1; Fig. 3 a cross sectional detail approximately on the line 3 3 of Fig. l with some of the interior parts left in elevation; and Fig. 4i a cross sectional detail on the line 4-4 of Fig. l.

The same letters of reference are used to indicate identical parts in the several views.

As shown in Fig. 1, the closet bowl A is provided in its upper rear portion with a chamber B which communicates with the flushing rim C of the bowl by ports a, and directly with the bowl by ports b, and is provided in its top with a central opening D, which in the present instance is approximately elliptical in shape. The top of the chamber B constitutes the seat-shelf of the closet bowl, and upon it rests a metal casing E having an opening in its bottom coincident with the opening D in the top of the chamber B, and secured to the latter and the bowl of the closet by the bolts F shown in Fig. 3. A packing ring seated in a groove formed in the bottom of the casing E around the opening therein secures a tight joint between the bottom of the easing and the top of the bowl. At its rear end the easing E is provided ywith a pipe connection G for the water supply pipe, while the upper side of the caslng 1s provided with a connection H for the lower end of the pipe which leads upward to the closed tank (not shown) supported in the usual position above the closet.

A chamber J formed in the rear portion of the casing E, in oper. communication with the connection H and pipe leading to the tank, communicates with the water supply through a central opening K in its rear wall, and with the interior of the main portion of the casing E and the chamber D through a coincident but larger opening L in its front wall. The opening K in the rear wall of the chamber is controlled by a valve 0, and that in the front wall by a valve P, opening in opposite directions and both carried by the same valve stem Q. The front end of this valve stem has its support and bearing in a plug R screwed into an opening in the front wall of the casing E, while its rear end is supported and guided by a disk or flange S snugly fitting within the pipe connection G. This disk or flange, which is provided with perforations or peripheral notches to permit the free passage of the water, is in the present instance formed upon a short supplemental valve stem S seated in a bore in the rear end of the main valve stem Q and having a conical front end whose point alone bears against the end wallet the bore in the valve stem Q, for a nrpose hereinafter described. The valve 8 is secured upon the stem S. A coiled spring T bearing against the outer side of the flange S and confined within a housing U coupled to the connection G by a nut U serves to press all of the parts forward and yieldingly hold the valve O against its seat and the valve P away from its seat. When, however, the valve stern and valves are forced rearward the valve P will be closed and the valve O opened, and water will be permitted to pass from the supply pipe through the chamber J and pipe connection H and pipe to the tank, filling the latter' to the limit permitted by the air in the tank. When the valve stem and valves are thereafter released the spring T will restore them to normal position, closing the valve O and cutting 0H the water supply, and opening the valve P and permitting the tank to discharge its contents through the opening L into the chamber B, and thence to the closet bowl through the ports a and b, and through a` suitable connection to the jet of the closet, if the latter be of a character employing a jet.

The valve stem Q is operated, to open and close the valves 0 and P', in the manner and for the purpose described, by a connection with the closet seat V, the rearwardly and inwardly extended hinges `W of which pass through stuing boxes KX in the opposite sides ot the casing E, Figs. 3 and 4f, and their inner endsprojecting within said casing, are squared as shown in Fig. l and have secured upon them a hub Y provided with a pair of depending arms Z Z'embracing a sleeve or hub Q secured upon the valve stem Q, as best shown in Pig. 3. The lower extremities ot the arms Z Z project in front of lateral studs or projections Zl Z upon the sleeve or hub Q', shown in Pigs. 1 and 3.

ln the normal position ot the parts the seat V is slightly elevated, as in Fig. l; and when it is depressed-upon the closet bowl the lower ends ot the arms Z Z are swung rearward, carrying the valve stem and valves with them, and closing the valve P and opening the valve 0. rPhe tank is thereupon filled with water, and when the pressure upon the seat is relieved the spring T restores the parts to normal position, closing the valve 0, and opening the valve P and discharging the contents ot the tank into the closet.

P or the purpose of permitting an adjustment of the parts'which will cause the valve P to come to rest upon its seat at the instant the closet seat comes to rest upon the closet bowl, the flanged hub or sleeve Q is adjustably mounted upon the valve stem Q by a threaded engagement therewith. Upon unscrewing and removing the plug R which supports the irontI end ot the valve stem, a screw-driver may be inserted through the opening in the 'front wall of' the casing E, from which such plug has been removed, and engaged with a nick in the front end of the valve stem, land the latter be turned to adjust the hub Q forward or backward upon the stem, to bring about the proper relation between the movements dof the valve P and closet seat. The provision ot the supplemental valve stem S tor the valve Q enables the latter to be readily removed, for inspect-ion and repairs, without removing the valve stern Q and valve P; while the pointed bearing orv the front end of the stem S against the end ot the bore in the stem Q relieves the friction between the parts and enables the stem Q to be easily moved, in the manner and for the purpose above described, notwithstanding the strong pressure of the spring T.

The seat hinges W W terminate at their forward ends in horizontal plates W W secured to the top ot the seat V by screws, and in vertical plates lllf2 WZ secured in like manner to the rear edge ot the seat and Ahaving an overlapping joint K as shown. IThis nineties ing the valve Q cooperating with the opening K, the spring 'P operating to press the valves and valve stems forward, and the seat lf hinged to the casing E and operatively connected to the valve stem Q to torce the same and the valves 0 and P rearward when the seat is depressed; substantially as described.

2. ln a water closet of the character described, the casing E having the pipe connections Gr and H and the chamber J having the openings K and L in its opposite walls, the threaded valve stem Q having its front end supported and guided in thel plug R in the front wall of the casing l2, the hub Q threaded upon the valve stem Q, the hinged seat V, an operative connection between said. seat and the hub Q upon the valve stem to cause the latter to be forced rearwardly when the seat is depressed, the

coiled spring 'll pressing the valve stem and guided at its trent end in the screw plug R, the hub Q threaded upon said valve stem, the seat V having its hinges W W journaled in the, casing E, and. the hub Y mounted on said hinges and provided with the depending arms Z cooperating with the hub Q to torce the latter and the valve stern rearward when the seat is depressed; substantially as described.
