To all whom it may concern;

Be it known that I, RUDOLPH HENRIK PAUS, a subject of the King of England, and residing at Shipley, in Yorkshire and .the Kingdom of England, have invented cer-v tain new and useful Improvements in Flushing-cisterns, of which the following is a specification. Y

This invention relates to flushing cisterns of the siphon type for water closets, urinals, and other appliances and has for its chief object to produce a cistern which will be absolutely silent in its action. Various devices have been proposed with a view to efi'ecting this object such for example as one or more pipes or passages of small bore which enter the siphon at or about its highest level and extend to within a short distance above the level of the siphon inlet aperture. Apparatus of this kind while efl'ecting great improvements over the ordinary siphon cistern is not absolutely silent as there is still a certain amount of noise produced by the inrush of air through the small pipe or pipes as the water level in the cistern arrives at and falls below the end or ends of such pipes.

According to this invention in order to eliminate this last mentioned objection an airpipe is employed which extends above the highest water level and opens to the atmosphere directly, or throughthe intervention of a silencer or if desired such a pipe entering the short leg of the siphon or terminating. in an open chamber and occupying a position slightly above the lower end or ends of the aforesaid silencing pipes, the arrangement being such that as the water level J; in the cistern falls during a flushing operation it falls simultaneously in the air pipe and chamber and opens such chamberto the atmosphere before the level of the water in the chamber reaches the ends of the small silencing pipe or pipes therein and any bubbling or hissing that may be caused by the water .level uncovering the lower end or ends of the "last mentioned pipe or pipes is effectually silenced by the inclosing wall of ipe whichextends above the highest water l evel and terminates as already mentioned in a silencerfif so desired. a I 7 In order that the said invention may be clearly understood and .ireadilycarried into Specification of Letters latent.

Application filed. May 24, 1915. Serial No. 30,185.-

eflect the same is described by way of ex ample with reference to the accompanying diagrammatic-drawings, in which Figure l is a longitudinal section of a flushing cistern showing the invention applied to a siphon having a vertical, siphon operating cylinder. Fig; 2-is a similar view showing the invention applied to a siphon having a horizontal siphon operating cylinder and the air pipe leading to the atmosphere through the intervention of a silencer. Fig. 3 shows the invention applied to a bell siphon. f

Fig. 4 is a similar View showing the invention. applied to ,a type of valveless bell siphon, and y V Fig. 5 shows a modification in which the air pipe enters the short leg of the siphon. A indicates the siphon, B, B, B the silencing pipes, C the air pipe, D the silencer, E the highest water level and F the lowest water'level.

In the exa nplesshown in Figs. 1 and 2 i jects into a casing or chamber 0 with the lower ends; occupying aposition that is somewhatbelow the lower end of the pipe 0.; The'upper end of .this pipe extends above the highest'water level and may open directly to the atmosphere as shown in Fig.

lorif desired, may be fitted with a silencer D; Fig. 2. In the example shown, this silencer comprises a casting containing two perforatedpipes d d separated from one another by a diaphragm (Z which is formed with perforations outside the pipes d d and causes the entering air to travel in the direction indicated by the arrows. This silencer is shown by way of example only and any other appropriate type may be used. The pipes B, B, B 'areformed at their upper portions with small apertures or pin holes I) and any suitable means can be employed for operating the siphon such for example asa piston mounted in a cylinder which may be vertical as shown at a in Fig.1 or horizontal as shown ata in Fig. 2', water entering through the bottom of the cylinder a or byway of an aperture or valve a in the cylinder a. The chamber or casingc can be made of any shape to suit the. design of the cistern and if desi-red'can be cast in'a piece with the siphon operating cylindera or a, the bottom or lower part of the chamfreely in and out and always be at the same level as the water in the cistern. In'the ex ample shown in Figs. 8 and 4:, A indicates a a bell that'con'stitutes the short leg of the siphon and also serves as all-OPEIablI-lg cylinder. One of the silencing plpes B opens into the top of such bell and extends downward'ly outside the chamber orcas'in'g 0 which is open at 0 and may be formed in a piece with the bell. Projecting from the top of suchcasing is the air pipe C which may be constructed and arranged to operate in the manner previously described. -In these examples only one of the silencing pipes B is shownbut if desired :two or more of such pipes may be used as shown with reference to Figs. 1-and'2n- Fig. 5 shows an example in which the supplementary chamber-or casing c is dispensed with, the air pipe C entering the short leg of the si-pl ion at (7 just above thes'iphon inlet aperture 0 In thiscase the lower end of the air pipe is open and terminates at or about theleve'l of the siphon inlet aperture.

I Vhen the silencing pipes are used in connection with a supplementary chamber 0 the small pin holes Y) may be dispensedavi-th.
