Specification of Letters Patent.

Patented July 25, 19522.

1 0 all whom it may concern Be it known that I, Lno SoLHnm, a citizen of the German Republic, and residing at Dusseldorf, in the German Republic, have invented certain new and useful limprovements in Flushing Apparatus, of which the following is a specification.

The present invention has reference to improvements in flushing apparatus such as used for instancein connection with water closets and urinals, and it relates more particularly to that class of: flushing apparatus in which, by the lifting of a siphon bell, variable quantities of flushing water may be discharged from the supply tank, for enabling the user to obtain full or partial fiushings at will.

For the purpose of explaining the inven tion a constructional embodiment thereof has been shown in the accompanying draw-- ing, in which the same reference characters have been used in all the views to indicate correspondii'ig parts. In said drawing.

1, is a longitudinal section of the apparatus,

Fig. 2, is a plan of the same,

Fig.3, is a cross-section of the same, and

Figs. 4: and are a vertical section and a plan view showing the aerating valve of the siphon bell on an enlarged scale.

Fig. 6 is a fragmentary vertical section through the siphon means in the position of rest, and Fig. 7 shows a similar section with the bell in raised position discharging water through the lower ports.

In the drawings the new flushing apparatus is shown by way of example in connection with a water-closet, which latter comprises the several elements well known in the art. The flushing pipe (I leads from the supply tank a: to the closet bowl. From the siphon bell it depends the standpipe a, rigid and concentric therewith, with its packing washer t, which pipe is provided near the upper extremity with passages q and below with passages The bell is operated by a rock-lever e, fulcrumed to the tank at 2', to the other end of which lever is linked the pull rod 8 with handle 9. The supply of water to the tank :is controlled by the valve is operated by the float Z.

The operation of these parts is succinctly the following: If the bell u is lifted (Fig. 7) by a straight pull on the rod .9, water will flow from the tank through the passages 2 into the flushing pipe a. The

flowing water entrains air out of the pipe 12 and thereby immediately causes air rarefaction in this pipe. It now, after a short lift, the bell is let down again by letting go of the pull rod, this rare-faction will suck up water standing under the bell, so that it will flow through the ports q into the central standpipe 12; and this will continue as long as there is water in the tank, since the column of water discharging through the flushing pipe a con inuously siphons water out of the tank.

To the top of the hell it an air-vent pipe r is secured which is provided with one or more'air inlets 0 adapted to be closed by a rotary valve 0 in the form of acylindrical cap having ports 0 corresponding to the inlets 0. The valve 0 is adapted to be operated by means of an arm it made integral therewith. The said arm is connected by a link f with a horizontal arm Z; forming the upper end of the drawbar s and acting as a lever. The drawbar is mounted along the wall, so as to be capable of longitudinal and rotary motion. The rotary motion of the valve 0 is limited in one direction by a. cranked portion 41 of the link f and in the other direction by the contact of the arm Z) of the drawbar s with an abutment piece to of the flushing tank x. The lower end of the drawbar has a horizontal arm 9 which may be provided with instructions for the use of the apparatus.

It the rotary valve 0, the lever mechanism j, Z) and the handle 9 occupy the position shown in Fig. 2 by full lines, the air inlet of the tube 7' is open, because the lateral perforations of the tube 1" and cap 0 correspond.

If it is desired to produce one or several weak flushing actions, it is sufficient to turn the lever h from the position shown in Fig. 2 by broken lines into the position shown by full lines, thereby opening the air inlets of the aerating tube, then to pull the drawbar s downward and, when the desired quantity of water has been dis charged from the flushing tank, to release the handle and drawbar. This operation may be repeated several times, as long as the tank contains flushing water.

If it is desired to produce a strong flushing effect and to discharge the whole contents of the flushing tank, the drawbar s, after the lever it has been turned into the position shown in Fig. 2 by broken lines and thereby the air inlet closed, is drawn downward and then released again (as is done in ordinary flushing apparatus).

With this invention it is possible, in case a full flushing action has been started by mistake, to interrupt the same, for which purpose the handle 9 is turned and thereby the air inlet opened.

On the other hand it is possible, to convert an accidentally started partial flushing action into a full flushing action by closing the air inlet, while the partial flushing is in progress.

While in describing the invention reference has been, made to as particular example embodying the same I wish it to be understood that my invention is not limited to the construction shown in thedrawing, and that various changes may be made in the general arrangement oi the apparatus and the con struction of its parts without departing from the invention.

1 claim:

1. In a flushing apparatus of the character set forth, in combination with a siphon bell including a central standpipe presenting top and bottom ports, and means for operating said siphon bell, an aerating device for atwill preventing air rarei action within said siphon bell, and said aerating device adapted to be operated by a movement of said siphon bell operating means difi'erent from that for operating said siphon bell.

2. In a flushing apparatus of the character set forth, in combination with a tank, a fioatcontrolled water valve, and a siphon bell, including a ported standpipe controlling the tank discharge, aerating means located wholly above the normal water level in said tank and communicating with the interior of said siphon bell, means including a pull rod for operating said siphon bell by a 1011- gitudinal pull and for operating said aerating means by a rotary movement of said pull rod.

3. In a flushing apparatus of the character set forth, in combination with a siphon bell including a rigidly centrally depending ported standpipe, pull rod means for operating said siphon bell for full fiushings, and means for operating said siphon bell for partial flushings, comprising a ported casing on said siphon bell above the normal water level and communicating with the interior of said bell, a ported cap over said ported casing, and means operated by said pull rod means for relatively displacing said cap and said casing for placing the respective ports thereof into or out of register. i

l. In a flushing apparatus of the character set forth, the combination with a tank in cluding a float-controlled water inlet, of a siphon bell, including a ported standpipe, controlling the water outlet, siphon brealn ing means comprising a casing having ports and communicating with the interior of said siphon bell, a cap snugly holding said casing and presenting ports adapted to be placed into or out of register with said casing ports, and said ports lying above the highest water level in said tank, and means for operating said siphon bell for full flushings by a straight downwardly directed movement and for operating it for partial flushing-s by a combined downward. and rotary movement of one of the elements of said operating means, thelatter comprising a pull rod, a cranked handle at the lower end thereof and a lever arm at its upper end, a rock-lever pivoted to said tank and linking said pull rod to said siphon bell, a lever arm extending laterally from said siphon breaker cap, a link connecting said cap lever arm to said pull rod lever arm, and means limiting the operative displacement of said siphon breaker operating means.

In testimony whereof I aflix my si nature.
