To all whom it may concern.- I

Be it known that I, BERNARD M. DRAWE, a citizen of the United 'States, residing at Sandusky, in the county of Erie and State of Ohio, have invented a certain new and useful Im rovement in Water-Closets, of which the fo lowing is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide an efficient water-closet which may be operated directly by the pressure in the main.

The invention comprises mechanism whereby a simple operation of a lever or other suitable release initiates means which automatically open a gate, allowing the water to siphon the bowl. 'An auxiliary jet is provided at the base of the bowl to augment the siphoning action. These and other features are comprised within the invention, which may be most conveniently summarized as consisting of the construction and combination of parts hereinafter more fully explained, and definitely set out in the claims.

. In the drawings, Figure 1 is a vertical longitudinal section through the closet. Fig. 2 is a side elevation thereof, partly broken away. Fig. 3 is a side elevation on the side opposite Fig. 2 Fig. 4 is a vertical section on the line 4 4 of Fig. 3 looking to the right. Fig. 5 is a horizontal section substantially on the line 5 5 of Fig. 1. Fig. 6 is a horizontal section on the line 6 6 of Fig. 1, showing also the baseqof the structure. Fig. 7 is. a detail in horizontal section on the line 7- 7 of Fig. 4.

The same letters of reference designate the same part in each figure.

As shown in th drawings, the bowl, base, and the various chambers hereinafter described may be made of one'-pieceas castiron or porcelain, for example-while the gate mechanism is a self-contained structure removable therefrom. Thestationary part A includes the base-plate a, the sides a, the front a", the bowl of, having a rolled-over upper edge a which supports the seat. (Not shown.) At the base of the bowl a passageway a leads upward beneath the wall (1 of the bowl, over a diaphragm a and then downward at a between the diaphragm a p and the front wall a. into the passage-way a". The exit from the passage-way a leads bel sage-way b, which, as stated, is carried by the separate gate mechanism B.

- In normal position the exit is closed by the curved gate 1), which engages at its lower end with the base-plate b and near its upper end with the member 11 which forms a tlght connection with the lower portion of the bowl.

At its upper end the gate is rigidly connected 7 with a ucket I), this whole gate structure being pivoted at b on the upper side of the wall I) of the discharge passage-way.

On one side of the structure a tubular passage-way C leads from the bend a to a pocket a. directly over the bucket, while on the o posite side a passageway D leads from tl fe chamber a (which has valved communication with the main, as hereinafter explained) to the pocket at at the base of the bowl.

' The purpose of the particular features of construction above described can be best un- 'der'stood from an explanation of the flushing operation. In normal position the water in point of the dia hragms a and c When it is desired to flusthe bowl, water is admitted by the operation of the valve H, as hereinafter explained, into the chamber a, from the bowl stands on a level with the meetingwhence it flows into the opening a and thence into the passage-way a in the rolledover edge a at the upper end of the bowl.

The water continues to flow from this source. 7

until the passage-way a is entirely filled, as

well as the space between the diaphragm a I and the front wall (1, the water rising high enough in these places to enter the upper end of the tubular passage-way O. Thereupon water flows through this pipe 0 into the 1 pocket a and thence into the bucket 6 until Q such bucket is more or less nearly full, whereupon the weight of the water in the bucket causes it to-swing downward, raising the gate b and releasing the water in the bowl and the passage-ways a and a, which thus goes into the dischar e-o ening with arush, effectively siphoning t e owl. During the siphoning water from the chamber a passes by the ipe D into the pocket a at the base of the bowl and is discharged diagonally u ward through an inclined opening a, an thus flows up along the diaphragm a efiectively boosting or; augmenting the flushing operation.

I At the beginningof the flushing operation 4 the bucket 12 is swung down into its lowermost position, thus causing a pin 1) on the valve to impinge against the wall b opening this valve and releasing the water therein, which 5 passes through the opening I) into the discharge passage-way. The valve-openmg b is made of such size that the desired interval of time elapses after the bucket has swung down before it becomes sufficiently empty to 10 return. After the bucket has emptied itself the gate b swings back by gravityinto the normal position, thus closing the exit. A hole I) is made through the plate I) of the bucket,

so that water will remain on the front side of the bucket and retard its downward operation.

It now remains to describe the manuallyoperated mechanism for turning on the water and the automatic arrangement which results in its being shut off at the proper time.

The operation is initiated in any manner desired. As shown in the drawings, a hand-lever E is provided for the purpose. This lever is pivoted to the frame on a rock-shaft which I 2 5 carries an internal arm E, extending through a vertical rod F. Thus when the hand-lever is raised this rod is raised. The rod is guided in the chamber a and at its lower end passes I through a lever G, which is connected with the stem h on the main valve H. The bonnet I-I, surrounding this valve, is connected with the water-main. When the rod F is raised, the disk f on the lower end thereof engages the lever G and swings it to lower the va ve H, thus opening communication with the water-main, whereby water is admitted to the chamber a. In the above-described movement the disk f on the rod F engages and passes above the spring-finger j, whereby the valve is held open, so that the operators hand may be removed from the lever E as soon as it is raised. The valve H being held open, water is admitted into the chamber a, and from thence some of it passes out through the opening a into the outside pipe D, furnishing the boosting-jet through the opening a into the base of the bowl, as here inbefore explained. The raising of the rod F causes the diaphragm f, carried thereby, to pass above the opening a, leading to the annular passage way a, wherefore Water is admitted to such passage-way and flows from thence into the bowl, and after it has reached the proper height in the bowl and in the exit 55 passage-ways therefrom it flows back through the outside pipe 0, as hereinbefore explained, into the bucket. When the filled bucket tips, it engages a rod j, depending from an arm 7' rigid on a rock-shaft which carries the spring-arm j". This movement rocks the s aft, so that the spring-arm j releases the disk f but just preceding such release a second arm f, carried by the rock-shaft, engages beneath a projection g on the lever G and 65 holds it elevated. The flow of water thus continues until the bucket swings back into normal position. In this movement the rod j is again engaged to swing the rock-shaft to cause the fingers j and j to return to normal position. In this movement the finger j swings idly above the disk f (which when released dropped down below the path of the fmger,) and the finger j releases the projection g, thus allowing the valve to close, which it does gradually, the disk f on the rod F pre- 7 5 venting too sudden movement. The rockshaft is carried by a suitable stufiing-box or similar member j, while to prevent the leakage of sewer-gas around such rod the rod carries a cup j which catches water leaking around the rod, and thus makes a water seal.

A removable plate K is secured to the side of the casing op )osite the elbow of the admission-pipe. The removal of this elbow and this plate allows suflicient access to the inte- 8 5 rior for the purpose of installing and adjusting the arts.

It wi 1 be seen that the operating mechanism for the gate is entirely on the sewer side thereof and that there is no mechanism in the passage-way between the bowl and the gate, so that when the gate is open there is an unobstructed conduit to the sewer. This is an important point, as it prevents the collection of waste matter on the forward side of 5 the gate. The water seal in the cup j prevents any sewer-gas from passing up into the chamber a, while any gas which passes into the chamber a is prevented by the water in the bend of the pipe C from entering the bowl. The water normally standing in the bowl above the lower end of the wall a forms the usual seal at this point.

The positive gate across the discharge-pipe besides being useful in most installations in barring the sewer-gas from the bowl is espe ciall advantageous when the fixture is used ons pboard, where the gate prevents water swashing up the discharge-pipe from backing into the bowl and spattering therein, as frequently happens with many fixtures.
