Application filed May 16, 1918. Serial No. 234,897.

To all whom t may concern:

Be it known that I, Hnnnmr'rn BoUnsmn, citizen of the Republic of France, residing in the city of New York, county andState of' New York, have invented certain new and useful Improvements in Controlling Mecha nism for Flushing Systems, of which the :tollowing is a specification.

This invention relates'to flushing systems; and it proposes, briefly, an apparatus ofthe general class or character specified having an improved controlling system for the water supply by means of which a llushing action is obtained immediately upon the operation of the controlling lever or its equivalent, the parts associated with said lever being arranged within a tank which, instead of normally containing water, is normally empty, but is filled almost as soon as the'lever is actuated, the water in the tank controlling the position of' a float which, in turn, serves to closethe water inlet or` supply valve previously opened consequent upon the operation of the lever.

The invention resides more particularly in Vthe construction and arrangement of' the parts or devices above indicated; but it is to be understood, of course, that no limitation to the precise structural details of said parts, as disclosed in the accompanying drawing, is contemplated, excepting as imposedby the Y terms of the claims appended hereto, since modications and changes may Vwell be made within the scope of saidclaims, and various parts maybe used without others and in other and different environments.

In said drawing: Y

Figure 1 is a sectional perspective view of' one form which the invention may take in practice, and Fig. 2 is a sectional elevation .of a modification.

The tank element of the system is doublewalled, and, as shown inthe drawing, coinprises outer and inner members 1 and 2 spaced from each other at all points to provide an intermediate chamber of the same' shape as the tank members themselves, the latter, in the present instance, being opentopped. This chamber is utilized for overflow purposes to convey the water to the flushing pipe 11 that leads to the bowl (not shown) and opens through the bottom wall of the outer member 1, the excess water passing into said chamber through a series of openings 12 formed in the upper portions of the walls of the inner member 2, according to the construction represented in Fig. 1, and

over the upper edges of said walls in the form depicted in Fig. 2. Water isdelivered to the pipe 11 for liushing purposes, and, incidentally, to the tank, by means of an inverted U-shaped pipe 3, one branch of which leads upwardly through the bottoms of' the tank members 1 and 2, while the other or downwardly-extending branch opens at its free end through the bottom of the inner' member 2 at a point directly above the open upper end of the flushing pipe, this being true of both forms of the invention. The first-mentioned or ascending branch of the supply pipe is provided with an internal valve seat Ll, in the form shown in Fig. 1, with which a valve 5 coperates, the latter' being secured to the lower end of a vertical rod 6 which extends axially through said branch and projects through an opening 8 in the top thereof. rl`he valve is normally held in closed position against its seat 4: by the pressure of the water against its under face, and is opened by depressing a. lever 24 to which the upper end of rod 6 is fastened, one end'of the lever being pivoted in a bracket 23 mounted on the top of the tank, while its other end is equipped with a handle 25. The horizontal or connecting portion of the U-shaped supply pipe is formed in its under side with a relatively large opening 9, and the bottom of the inner tank member 2 is provided with an opening 13 of about half the size of the said pipe opening, the opening 13 serving as an outlet Jfor the water in the tank and the opening 9 as an inlet or filling opening therefor. Hence, when the lever 24 is operated it will immediately lower the valve 5 from its seat and permit water to rush through the supply pipe and intothe flushing pipe 11, the apparatus as a whole being primarily designed for use in connection with highpressure water service, such as is generally found in large cities at the present time. A portion of the water flowing through the latter pipe will, however, pass out through the opening 9 into the tank, and, by reason of the difference in size of the openings 9 and 13, will commence to fill the tank. The pipe 3 has a relatively-large diameter, as ccmpared with the tank, which latter, as will be seen from the drawing, is comparatively small, and the opening 9 is likewise relatively large, as has already been stated.

When the tank is filled the water will hold the float 19 in the position shown in full lines in Fig. 1, the float being suitably connected to the rod 6 so as to hold the valve 5 open, thus permitting the release of the pressure on the handle 25. The float is in the form of a rectangular boX or body and its function is to automatically close the valve 5 when the filling operation has continued for a certain period andwhile the `tank is still full, thereby shutting off further supply of the water. The tank thereupon empties through the opening 13, the water passing through the bottom portion of the intermediate chamber above referred to and thence into the flushing pipe. The float is carried 'by a rod 16 pivoted to the upstanding arm 15 of an annular bracket 14- suitably fastened to the ascending branch of the supply pipe 3. The portion of the float rod or lever between the float and the bracket arm 15 includes a ring member 17, which encircles the descending branch of the supply pipe and is of sullicient diameter to permit the movements of the float, Vwhile the free end of thc said rod extends through a vertical slot 1S in the ascending b anch and is loosely engaged in an elongated eye 7 with which the valve rod 6 is centrally provided, so that the depression of the valve rod will raise the float from its normal position, shown in dotted lines, to its elevated or full line position. The float is designed to be filled with water, after having been raised into the latter position, and, when filled will sink back to its lower or normal position, during which movement it will raise the valve rod and automatically close thc valve. To permit the entrance of the water into the float, an opening 20 is formed in said float adjacent its bottom, the air being forced out by the incoming water through a plurality of openings 21 in the top of the float which may be covered or uncovered at will byVv a slide 22 in ordcrto regulate the speed at which the float fills, thus regulating the time during which the valve 5 is held open by the float.

The operation, briefly described, is as follows z--Depression of the lever 24 lowers the valve rod 6, thus raising the float 19 and opening the valve 5, with the result that water flows through the supply pipe 3 and into the flushing pipe 11, a portion of the water entering the tank by way of the opening 9. Then the tank is filled to the point where the water enters the float, which takes place almost innnediately, due to the small size of the tank, as con'iinired with the diameter of the supply .pipe and its opening 9, and to the pressure of the water, the said float gradually descends, raising up the valve rod and closing the valve. The tank empties into the flushing pipe through the opening 13, the float itself emptying through the opening 20.

The modification represented in F ig. 2 diers from the first form only in certain details. Thus, the operating device is constituted by a straight, vertical rod 30, the lower end of which is Vloosely connected to a lever 31 that serves both to open the inlet valve 32.and to raise the float 33.V rlhe parts 32 and 33 are substantially identical with the corresponding parts 5 and 19, excepting that the valve cooperates with a seat 34 which is formed in a partition 35 provided in an enlargement 36 ofthe central or horizontal portionof the supply pipe 3, and that the float is supported upon a ring 37 that encircles the aforesaid pipe portion. r1`he lever 31, in addition to the ring 37, includes a second ring 38, which encircles the descending branch of the supply pipe,-in this case, the Vrighthand branch-and is pivoted upon the lower end of a bracket 39l suspended `from the connectingportion of the pipe, the valve 32 being attached to the upper end of a vertical rod or stem 40, the lower end of which has fixed to it a second valve 41 that cooperates with a seat 42 formed in the bottom of theinner tank member 2. This valve 41 takes the place of' the opening 13 in the first form of the invention, and is normally held in open position due to the fact that the upper valve 32 is normally kept closed, both by the pressure of the water in the inlet or ascending side of the supply pipe and by the Weight ofl the float, which is also the case in the first form, the central portion of the valve rod having an eye 43, or equivalent thereof, with which the adjacent portion of the lever is engaged. The supply opening 44 for the tank is lo cated at the intersection of the descending and connecting portions of the supply pipe, f

instead of in the latter portion. The waterV and air openings in the float are indicated at 45 and 46, and the controlling device for the said air openings at'47.'

The operation, as will be understood, is the same as inl the first form, excepting that the depression of the rod 30 serves to' close the tank-emptying valve 41 at the same time that the supply or inlet valve 32 is opened and the float raised. `The parts remain in this position until the float fills and `commences to descend, whereupon the inlet valve closes and the drain valve opens.
