R. STIGKDORN. FLUSHING APPARATUS FOR WATER GLOSETS. APPLICATION FILED AUG. 19, 1909.
ROBERT STICKDORN, OF DUSSELDORF, GERMANY.
FLUSHING APPARATUS FOR WATER-CLOSETS.
To all whom it may concern:
Be it known that 1, ROBERT S'rroxDoRN, a citizen of the German Empire, residing at Dusseldorf, Germany, have invented new and useful Improvements in Flushing Apparatus for Water-Closets, of which the following is a specification.
The special feature of the new distributing mechanism consists in the arrangement of an automatic valve closing-member in the water-inlet socket, being at a right angle relative to the main valve-box, in the provision of special mechanical motive means for same, further in its being shaped for shutting up the box in either sense and besides in the placing of the inlet socket below the connecting arm intermediate the flushing-box and the distributing case.
In the accompanying drawing: Figure 1 is a perspective View of my improved flushing apparatus, showing it applied to a water closet; Fig. 2 a vertical section through the valve, and Figs. 3 and 4 are similar sections showing the parts in different positions,
Within a valve casing b, is axially movable a valve plug comprising two pistonlike closing members h, and o, the diameter of member h exceeding that of member ?),'SO as to constitute a difierential piston. Members 72,, o are separated by a recessed plugsection a, and a coniform section in, the maximum diameter of cone 70 corresponding substantially to that of member h. Casing b, is provided with a water inlet nozzle or socket w, to which a water supply pipe'w is coupled. Above socket in there opens into casing Z), a pipe d connecting an air chamber with said casing. Nozzle w is provided with a pair of valve seats 8 and 25, adapted to be engaged by a disk-valve 0, the axis of which extends at right angles to that of piston h, 'v and which is provided toward either side with stopping-up faces and guided by means of ridges r. This is equipped with a chamfered knob or abutment 2 which, when the valve-disk has moved itself in the direction of the distributing case, so as to rest on the valve-seat 8, projects into the distributing case and is consequently adapted to be acted upon by the distributing body and to effect the same in turn.
The cycle of operations with the distributing mechanism is as follows :VVhen the distributing body is in the lifted position,

as shown in Fig. 2, the discharge from the air chamber 9 toward the down-pipe is free, as in this case the water can flow along by the side of the cone 7c and of the closing member, passing then through the cylindrical part b of the casing to the outlet leading to the bowl. On the other hand the water inlet is shut up, the pressure of the water forcing the closing member 0 against the seat 8. If now, however, the distributing body is pressed down by means of a pressure on the handle 0 of same, first the piston-like closing member '0 is moved in the cylindrical part of the case shutting this up. WVhen the distributing body moves down farther, the cone is strikes against the knob 2, thereby pressing back the valve-disk 0 from the seat 8, so as to allow the water to flow in and to enter into the air-chamber 9. As soon as the distributing body has been completely pressed down, the knob a, owing to the pressure of the water, passes over the cone-rim or shoulder 72, cliamfered away or slanted at the top, thereby retaining the distributing body in its position, as shown in Fig. 3. When now the cistern is filled and the same tension is obtained in this as well as in the piping, the distributing body is lifted, the prevailing water-pressure being able to exert in the well known manner on the piston-like part h, having the larger diameter, a greater force than on the body '0. "During this operation the valvedisk' 0 is slightly pressed back, due tothe chamfering away or slanting of the pivot a, and in given cases owing to the projecting rim of the cone; this takes place without resistance due to the equalization of the pressure in front of and behind the valve-disk 0. If now the cone has been lifted the distance sufficient, so that the valve-disk gets its posit-ion opposite the cylindrical part below same, as shown in Fig. 4, the valve-disk is free to move back to the seat 8 so as to close the influx of water. But all the same and due to the pressure prevailing in the air chamber g, the distributing body is lifted farther, that is, till the upper face of the closing member 0) strikes against the knob a, which prevents it from continuing its up ward movement. The closing-member o finally leaves the narrower part b of the case, as illustrated in Fig. 2, so that, after the opening of the valve 2), the water of the air chamber 9 flows to the basin of the closet, causing it to be flushed. hen press ing down again the distributing body, the same operation repeats itself.
In order to prevent the contents of the closet bowl from being drawn by suction into the water supply pipe through branch w whenever a reduction of pressure in said pipe should take place, piston h, is is made hollow, its interior communicating through ports 0 with the atmosphere. Thus when the parts are in their inoperative position (Fig. 2), the interior of easing Z) communicates with the open air through ports 0. As soon as a reduction of pressure occurs in the water supply pipe, disk 0 will be drawn against seat 25 to close branch w. If casing 6 would not communicate with the atmosphere, suction would be created therein whenever a reduction of pressure in the water supply pipe should occur, which suction would draw the contents of the bowl into casing b and branch w.

In a flushing apparatus for Water closets, an air chamber, a casing communicating therewith, a water inlet, a water outlet, a difierential piston within the casing and controlling communication between the casing and said outlet, a separate valve controlling communication between the inlet and the casing, and an abutment on the valve which is adapted to be engaged by the piston.
