FLUSHING-TANK.

Application filed November 25, 1913. Serial No. 802,857.-

Be it known that 1, WILLIAM A. KEEN, a citizen of the United States, residing at Baltimore, inthe State of Maryland, have invented certain new and useful Improve ments in Flushing-Tanks, of which the following is a specification.

This invention relates to improvements influshing tanks and has for an object to provide improved means for controlling .the

, supply of water to the tank and the outlet of the Water from the tank.

Another object is to provide improved means to control the outlet of water fromthe tank, whereby valved outlets will be dis-- pensed with together with their objectionable features.

'A further object of the invention is to provide a flush tank with an. automatic water supply and a-siphon outlet and to provide improved means for actuating the same. I

Anotherobject is to provide an improved float controlling means to eflect' a shut-ofl' of the water supply and to cause an actuation of the supply means.

With these and other objects in view the invention is illustrated in the accompany- 'ing drawings, wherein,

,Figure 1, shows a vertical longitudinal 1 section through a tank having my improved devices attached thereto. Fig. 2, illustrates the same in top plan view. Fig. 3, shows a cross-sectional detail through thefloat rode the section being taken on the line 3-3 of Fig. 1. Fig. 4, shows a similar section taken Referring to the drawings by numerals, 1,

designates a tank having a metal lining, 2, with a water supply pipe, 3, entering the tank and controlled-by avalve, 4, which in' many respects is of ordinary commercial construction. The nozzle, 5, however, of

a partition, 6, and a feed pipe, 7, leads sald valve-to convey water for a purpose' presently to be described.

The supply valve, i, has an; operating arm; 8, to which the rod, 9, of a float, 10,is at; tached. This arm is provided with a tubulan sleeve, 11, which has two stop shoulder s,-12,' and 13, at its forward end, asclearly shown in Fig. 8 of the drawing, The float,rod,l9',;

has its end extending loosely through; the

sleeve, 11-, so it mayroft'ate therein and aunt,

vents withdrawal of the latter from the sleeve.

14, on the projecting end of the rod prea extends downwardly, as shown in Fig.1?) of the drawlng. This arm is provided vat one side with a stop Slug, l6, whichhas position sleeve, 11, whereby the rod, 9, may rotate which is rigid thereon and which normally 1 between the stop lugs, 12, and18, onl,the i in the sleeve through an arc equalto the dis-.

tance between the lugs, 12, and 13,, as shown 1n broken lines in Fig. 3. The float rod, 9, has a and the sleeve, 11, at its inner end as shown 1n detail in Fig. 7 of the drawing.

17, therein intermediate the float, 10, at'its f outer end- I u I oint, 17,.perm1ts the outer member, 18-, of

the float rod to swing'upwardly while the:

rod is rotated in the sleeve but prevents said rod member from swinging up when the rod is in the position shown. in Figs. 1 and-2.

A rock-bar, 19, is mounted on the tank, 1,

in the present instance,'-so thatan operating chain, 20, may be attached to the outer end thereof, while a. link rod, 21, connects the inner end of saidfrock-bar with the arm, 15,.

on the float rod,.as clearly seen inFig. 1 It will therefore be seen that when the chain,

20, is pulled down, the link rod, 21, will swing arm, 15, up andthereby give a partial rotation to the float rod, 9, and the hinge joint, 17. This-partial rotationjwill change the positions of the arm, 15; hinge-j'oint-,'17,

and float, 10, so the same. will assume posi-.

tions'indicated by broken lines in Figs. 3, 4 and 5 and when the joint, 17, is soturned th-eouter member, 18, ofthe floatrod-will' immediately swing up because of the fhuoy-- I ancy of'the float, 10, whereupon the; operating arm, 8, of-the valve, 4, will drop to the.

position shown in broken lines inFig; l, 'andc allow plunger, 22, ofthe valve to raise and supplyrwaterif to the tank. through nozzle, 5.

ln front of theforward end of thesleeve,

The float, 10, is provided with a weight, 29, which when the operating chain, 20, is released, will cause the float to turn back to its normal position so as to reset the joint, 17, in the float rod.

The outlet of water from the tank is to be effected through a siphon tube, 23. This siphon tube extends through the bottom of the tank and connects with an elbow, 24, at the upper end of a flush pipe, 25. On the interior of the tank, the siphon tube extends vertically and has a back bend, 26, from which a short leg, 27, extends toward the bottom of the tank. This short leg has an open lower end which terminates above the bottom of the tank so that when the water level in the tank lowers to a point where the said open end is exposed the siphon action will be broken and discontinued.

The water feed-pipe, 7, from the supply valve extends upwardly and has a nozzle, 28, which enters the short leg, 27 of the siphon tube just below the back bend, 26, so that when water is supplied to the tank from the valve, 4, a stream of Water will be directed from nozzle, 28, of the feed pipe toward the back bend, 26, to cause the water to flow over said bend.

When the device is in readiness for operation the tank will of course contain water,- the level of the water being just below the bend, 26, when the float cuts off the supply from the valve, 1. At this time the leg, 27, of course, will be filled with water up to the level in the tank while the tube, 23, will be empty. Of course pipe, 7, will also be filled with water because its lower end will be exposed at the nozzle, 5, while its other or nozzle-end will be exposed to the water in the leg, 27, inasmuch as it is located below the normal water level.

lVhen the chain, 20, is pulled down, link rod, 21, will move up and arm, 15, will also swing up so as to partially rotate float rod, 9; hinge-joint, 17, and float, 10. This partial rotation of the float rod and float will turn the hinge joint so it can break, as shown in broken lines in Fig. 1, whereupon the rod,

9, and valve arm, 8, will lower and plunger, 22, will rise so as to admit water through valve, 4:. The admission of water through the valve will produce a supply in the feed pipe, 7, so that water will be projected from the nozzle, 28, into the leg, 27, of the siphon immediately below the water line and also below the normal water level. This supply of water through nozzle, 28, will cause an overflow of the water in the bend of the siphon and thereby set the siphon in action so that the water will flow out through the siphon faster than it can flow in through the nozzle, 5. This overflow will then continue until the lower end of leg, 27, is exposed when the siphon will be broken and the outflow of water cease. After the rod, 9, has

water and the weight, 29, on the float will cause the latter to rotate back to its normal position to reset the hinge. As the water then rises in the tank the float will rise therewith and when the proper level has been reestablish'edwthe float will cut otl' the inlet of water from the valve, 4:.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. In a flushing apparatus the combination with a tank having a supply pipe, of a valve in said pipe said valve provided with an operating arm; a rod connected to the arm; a float carried by the rod said float being heavier at one side to keep said side down when the float is in the water and hold the arm in the cut-off position; means for rotating the float to turn the heavier side up and means for relieving the operating arm of the float pressure when the heavier side of the float is turned up and allow the valve to open.

2. In a flushing apparatus the combination with a tank having a supply pipe, of a valve in said pipe said valve being provided with an operating arm; a rod connected to the arm and having a hinge joint; a float on the rod beyond the hinge joint said float being heavier at one side to normally maintain the joint in a rigid condition, and means for turning the rod to cause the joint to break.

3. In a flushing apparatus the combination with a tank having a siphon outlet and a water supply pipe, of a valve in the supply pipe; a rotatable float rod operatively connected with the Valve said float rod having a hinge joint therein; a float carried by said rod and holding said valve closed when the rod is in the normal position; means for normally holding the float-rod against rotation while the tank is filled and means for rotating the float-rod to break the hinge joint therein, whereby to admit water to and discharge water from the tank.

4. In a flushing apparatus the combination with a tank having a water supply pipe and also having a siphon-outlet, of a valve in the supply pipe said valve having an actuating plunger projecting therefrom; an arm operatively connected with the valve plunger; a rotatable rodhavinga hinge joint therein and at one side of the hinge joint said rod being connected to said arm; a float carried by the rod at the other side of the said hinge joint and holding said valve closed when the rod is in its normal position and means for rotating the rod to break the joint whereby to relieve the arm of the1 float pressure and admit water to the tan 1.

5. In a flushing apparatus the combina tion With a tank having a Water supply pipe, of a valve in said pipe; an operating arm for the valve said arm having a tubular sleeve; a rod having one end rotatably 'connected to the sleeve of said arm and provided with a hinge joint between its ends; a float at the other end of the rodand means for turning the rod in the sleeve to cause the joint to break.

6. In a flushing apparatus the combination With a tank of a Water supply pipe having a valve; a float rod rotatably attached to the valve and having a hinged joint therein and afloat at its free end beyond the hinge j oint,-said float being heavier at one side to 15 i In testimony whereof I aflix my signature 2d V V in presence of two Witnesses.
