SPECIFICATION forming part of Letters Patent No. 660,044, dated October 16, 1900.

Application filed October 7,1899. Serial No. 732,943. (No model.)

To @ZZ wir/0712, 'it may concern:

Be it known that l, JONATHAN BOWMAN, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Water-Closet Flush, of which the following is a specication.

My present invention relates to a novel siphon flushing apparatus for water-closets.

The object of my invention in its broadest aspect is to provide an apparatus which may be operated without waste, in which the quantit-y of water to be discharged at each ushing can bereadily regulated, and which will effectuallyeliminate the objectionable leakage incident to the employment of movable valves in the discharge leg or branch of the siphon. Subordinate to this general object are others, which will more fully hereinafter appear as the necessity for their accomplishment is developed in the succeeding description.

Referring to the drawings, Figure l is a sectional view of a lush-tank provided with my improved apparatus, the position assumed by the parts during the operation of flushing being shown in dotted lines. Fig. 2 is a sectional view through the discharge branch of the siphon, showing the regulator. Fig. 3 is a plan view of the piston. Fig. 4 is a View similar to Fig. l, showing a modified form of pump. Fig. 5 is a view similar to Figs. l and Ll, but illustrating another form of combined siphon and pump. Fig. 6 is a sectional View showing still another and possibly the preferred form of siphonic pump.

Referring to the numerals ot' reference on the accompanying drawings, in which like numerals refer to corresponding parts throughout the several views, l indicates a flushingtank provided with an ordinary form of supply mechanism 2.

3 indicates a flushing-Siphon comprising a comparatively-long discharge branch 4., eX- tending upwardly through the bottom of the tank and opening at its upper end into a cylinder 5, constituting the short or supply branch of the siphon, having a closed upper end provided with a cover or cap 6 and open at its lower end, which extends nearly to the bottom of the tank. 7 indicates a piston movable within the cylinder 5 and provided with peripheral packing S, one or more inwardlyopening or clack valves 9, and coaxial pistonrod 10, guided by the frame l1 and passing through the stuffing-box l2 above the cylinder, where it finally terminates in a bifurcated end 13, in which is revolubly mounted a rollernle.

indicates a flushing-lever fulcrumed, as at 16, upon astandard 17, carried by the tank and passing between the bifurcation 13 of the piston-rod and under the roller 14:. Thus when the ushing-lever is actuated by a pull upon the chain 18 the piston-rod will be rcciprocated vertically, causing the ascent of the piston within the cylinder, the parts being thereafter restored to their normal positions by a counterweight 19, the hook 20 of which is designed to engage one of a series of apertures 21 through the lever l5 beyond the roller la. It is obvious that when the piston V'7 is elevated sufficiently within the cylinder to discharge enough water into the long arm of the siphon to create siphonic action the water in the tank will continue to flow through the branch y-Ll and into the receptacle to be flushed until the level of water within the tank falls below the lower end of the cylinder. It is unnecessary, however, in most instances to discharge the entire contents of the tank at each flushing, and I have therefore devised a simple regulator by means of which the quantity of water discharged at each operation may be determined with accuracy, and which, unlike the ordinary float-controlled devices, will not continue the discharge when the tank has been refilled even though the pull upon the chain 1S be continued. In other words, I regulate the flush and necessitate a separate actuation of the flushing-lever for each flushing operation.

l have illustrated several forms of regulators, the essential feature of all of which is the breaking of the siphonic action by admitting air into the siphon at predetermined water-levels. The preferred form of this regulator, however, comprises a longitudinal slot 22 in the side of the branch of the siphon and extending from a point adjacent to the bottom of the tank, preferably to high-water mark. The branch pipe t is provided coextensive with the slot 22 with a longitudinal concavity 23, closed at the bottom, as indicated at 24, and having an open top 25, which IOO openscommunicaiion between the interior of the tank and the interior of the siphfon 'by way ot' the slot 22.

It will now be obvious that if provision be made for closing the slot along the upper portion the siphonic action will be continued until the water-level has reached the lower limit'of i the closure, at which time air will be admitted into-the Siphon and the siphonic action will thus be interrupted. It is precisely lin this manner that. the desired end is attained.

What I will term a regulating-shutter i 26, which is simply a longitudinal shield for i the slot 22, is slidably mounted upon the branch 4 over the slot and is provided at its upper end with ahandle 27 Vby means of which it may be raised or lowered, accordinglyas it is desired to permit the ingress of air to the interior of the siphon at any desired point. Thus the flush is regulated by the position of the regulating-shutter 26, and as water rises through the valves of the piston in Athe cylinder to same level as that in the tank the overiiow does not depend upon the air-regula'to-r. Of course Water will rise in the tube to level of that in the tank, just as in the cylinder, and the longleg of'siphon will form an overflow, whether the flush-regulator be entirely closed or not, whenever the water in the tank rises above the head of the long leg. A separate overliow maybe provided, if desired., at any point in the tankbetween head of long leg and high-water mark. At times, .it desired, a telltale-overdow may also be attached to the improved device and be of any well-v known form, the said attachment not being shown, because it will be well understood by those skilled in the art how its application could be made and the convenience arising from its use.

28 indicates a smaller tube extending upwardly from a point near the bottom of the tank and piercing the cylinder immediately i above its lower end. The tube serves the dual purpose of admitting water to the interior of the cylinder in the event of derangement of valves 9 and is designed to break; siphonic action in the event of its being del sired to empty the tank during an inflow `off Water sufficient to prevent 'the level from dropping below the cylinder within a reasonable time.

In Fig. 4 I have illustrated a modification which consists in substituting a vsectional telescopic cylinder 29 for the cylinder 5 and I its piston v7, (illustrated in .the first two iigures of the drawings,) the action of the pump thus formed being substantially identical with that shown in the lirst two figures .and therefore appearing to require no further description.

In Fig. 5 of the drawings I have shown a possible variation of the siphonic-p-nmp construction. In this instance the long dscharge or tiushing branch of the .siphon is; extended coaXially into a cylinder 36, provided with a regulator of the type illustrated in Fig. l and having an open top 37 above the water-level in the 4Itan'k. The bottom 38 of the cylinder is provided with upwardlyopening valves 39 and constitutes a pump the elevation ot' which by the actuation of the lever 15 will cause the water to be raised and directed through the liushing branch pipe.

In Fig. 6 of the drawings still another variation and .possibly a preferred construction is shown. The cylinder 40 has its upper end closed, and the upperinterior end of the tlushingpipe is provided with a Xed head or piston 4l, 'fitting snugly wit-hin the cylinder. Tfhepston is surrounded by suitable packing 42, and openings 43 are formed in the flushing-pipe just under the piston. Valves 44 open into the cylinder at its bottom, and it is provided with a regulator of :a -construction already described in connection with Fig. l of the drawings.

Obviously the construction and opera-tion of the regulator are not effected by its transposition from the fixed discharge branch 4 of the siphon (shown in Fig. 1) to the movable inlet branch or-cylinder, (shown in Figs. 5 and 6,) the only .essential being Ithat vthe siphonic action may be interrupted bythe ad mission of air at any desired water-level.

'The cylinder 40 constitutes a bell, and s pecial utility resides in the provision cfa closed air-.space between the station-ary piston .and the upper end of the lbell or cylinder. As the cylinder 40 is elevated the contained water will be discharged through the flushingpipe to create siphonic action, and as no airinletis provided above the piston the gradual enlargement of thetair-space will create a partial vacuum at the` upper end ot' the bell. The return of the bell or cylinder to its normal position will therefore -be effected without the necessity forthe employment of a weight, which would be necessary to return the piston were it `not for the-suction thus created.

From the foregoing it will be observed that Ihave invented asimple, durable, and highlyefficient flushing apparatus for closets, and while the present embodiment of my invention appears to be preferable I do not desire to limit myself to the details specified, but desire to change, modify, and vary them at 1 will Within the scope of the protection prayed.

What I claim is- 1. In a flushing apparatus, the combination with a tank, of .a cylinder disposed vertically therein having a siphon attachment, one of the latter parts being provided with a longitudinal slot and a longitudinal concavitycoextensive with the Vinside of the slot closed at its bottom and open at its top and constituting a regulating means, .and an adjustable covering device for regulating the said lslot and establish adjustable communica-tion between the .same and the part in which it is located to control the i-ush.

2. In a iiushing apparatus, the combination with a tank, of a siphon including a vertical IOO IIO

sive with the inside of the slot, closed at its bottom and open at its top and constituting a regulating-slot, and a regulator-shutter ad justably fixed over the slot and designed to determine the Water-level at which air will be admitted to the interior of the siphon.

In testimony that I claim the foregoing my own I have hereto alixed my signature in the presence of two Witnesses.
