Application filed J une 16, 1394:.
.To a/ZZ whom t may con/cern: A
Be itknown that we, JAMESA. OCONNOR and GEORGE H. GRAHAM, of Rochester, in the county of Monroe and State of New York,
' have invented a certain new and useful Iml provement in Flushing Attachments; and We do hereby declare that the following is a full,
clear, and exact description of the same, reference being had to the drawings accompanying thisapplication.
Our improvement relates to that class provided with elevated flushing tanks, and the invention consists in the .construction and arrangement of parts hereinafter described and claimed. Y
In the drawings-Figure l is a central, vertical section with the piston lowered and the water cut olf as when at rest. Fig. 2 is a similar view with the piston raised to its full zo extent as when drawn up to produce'the iushing action. Figs. 3 and 4 are similar views showing the piston in dierent positions in the down movement. Fig. 5 is a similar view with the cylinder removed. Fig. 6 is a 2 5 similar view showing a modification. A indicates an elevated tank, such as is used in ordinary water closets and urnals.
B is a barrel of cylindrical form resting inside the tank and provided with an'exit pipe On one side is an overflow pipe D, open at its top and communicating at its bottom with a' discharge passage D', that leads to the exit pipe C.
E is a jacket outside the barrel, and of larger diameter, closed at the top but open at the bottom, said bottom extending nearly to the bottom of the tank. In theactof flushing the water is drawn from the tank through this jacket space, and passes through ports o 0L 4o in the sides of the. barrel to. the interior. Hence. all, or nearly all, the water can be drawn from the tank, vwhich cannot be done when the jacket is not used.
G is an inverted cylinder inside the barrel,
v fitting closely to the sides but having free l movement up and'down. Its bottom is entirely open and its top partially so, having a flange b all around, with awateiway c in the center. It has ports d d in its sides rwhich FLUSHING ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 5131,212, dated December 18, 1894.
Serial No. 514,824. (No model.)
coincide with the ports a a of the barrel when the cylinder is down at its lowest point.
I-I is the piston. It has a closed bottom f, provided with' a packing g which shuts down on'a seat h, and thereby cuts od the passage from the interior of the barrel to the exit pipe C. Its upper portion z' is cylindrical and tits 'closely the sides of the cylinder G in which it rests, while its lower portion, 7s, is of less diameter and leaves an annular space between itself and the cylinder.
I is a piston rod attached to the piston, extending up through the barrel and pivoted at its top to the lever K, by which the piston is operated, or connected by suitable lever work with the hinged and movable seat ofV the closet, or some other suitable arrangement by which the'piston is operated.
L is a cup or vessel, open at its top but closed at its bottom, resting on the upper end of the barrel B and forming a cover to the same. The piston rod passes freely but closely through a central hole in the bottom ofthe cup. In ,the bottom of this cup is a screw m, which can be turned down as shown in Fig. 4. tohold the cylinder G in the bottom of the barrel and prevent it from rising. When the screw is turned up the cylinder can rseto the top of the barrel. Thev bottom of the cup is also provided with a conical valve n, resting in .a seat and provided with a vertical stem n. The valve is held in a curb o, in; the bottom of which are small ports p p which allow passage of water from the interior of the barrel ,outward through the valve when thepiston is raised. In the top of the curb screws a' plug fr, having a central hole to receivethe stem of the valve. By screwing this plug up or down the opening of the valve is regulated to the desired rapidity of the escape of the water outward from thebarrel.
The piston rod I is made tubular from the top downward a portion of its length, and in it are three orices, s t u, opening outward. Two of these orifices, s t, are near together, while the third one, u, is-farther up and at some distance from the others.
. Instead of the two holes st a slotot proper length may be used. l
fr is a screw which screws down into the open top of the piston rod and intersects the upper hole fu, when forced fully down.
In flushing the bowl the piston is drawn up by operatin g the lever K, or such other means as are provided. In passing up from the stationary position in Fig. l, the upper part of the piston uncovers the ports a ct and d d of the barrel and cylinder, which ports are then in alignment, and a preliminary iiushing action then takes place, thewater from the tank having free passage from the tank into the barrel, and from thence into the exit pipe. till the piston in its ascent strikes the top of the cylinder G and draws the latter up with it, and until the ports of the cylinder are raised above the ports of the barrel, when the lower closed part of `the cylinder cuts it off. This preliminary flushing 4action is for the purpose of wetting and cooling the bowl and washing it free of any adhering matter. The piston and cylinder continue to rise together till they reachothe top of the barrel. When released again they commence to fall very slowly, as the openings s t alare all above the bottom of the cup L, as shown in Fig. 2, and the parts can fall only so festas the barrel is filled above them by the natural leakage of the water through the joints from the cup above. This interval gives time tor `the use of toilet paper before the second flushing action takes place, in case the attachment is operated by the ordinary elevated seat. This second tlushing action cannot occur untilthe bottom of the ports d d of the cylinder reach the top of the ports a a of the barrel, as shown in Fig. 3. At this moment `the lower opening s of the piston rod passes through the bottom of the cup L, while the second opening t rests above it, as shown in Fig. 3. The. water in the cup now runs into the opening tand out of s into the barrel, and consequently accelerates the downward motion fof the cylinder and piston. Soon the second opening t also passes below the bottom of the cup, and the water then passes into the opening u and out of both s andt into the barrel. The accelerated motion opens the ports wide and .a rapid flushing action takes place, and this action continues after the cylinder has been seated and until the piston comes down and its upper enlarged portion cuts ed the ports. This is done before the piston itself is seated. The moment the bottom of the enlarged upper part t' of the piston rod comes to the top of the ports the opening u comes below the bottom of the cup, as in Fig. 4, and althoughthe iush still continues, the piston is retarded, as the barrel can be Iilled above it only by the natural leakage through the joints. Therefore it moves down slowly to beseated and produces no pounding action as is produced in many water closets.
less of water that enters the upper hole u. In
This flushing action continues The length of flushing action is regulated by means of the screw c, Q which can be forced down to cut olf more or l the up motion of the piston and cylinder the water in the barrel is discharged through the Valve n, as before described.
In this apparatus the down motions of the piston and cylinder are regulated by the passage of the water from the cup L into the barrel, while the flushing water passes into the bottom of the barrel directly from thc tank. The elevated cup is an important feature of the invention, since it always holds a body ot' water sufficient to regulate the movements of the piston and cylinder, however low the water may be in the tank. When the tank is filled alternately with each flushing the cn p is also tilled and holds a supply when the water is drawn oft from the tank.
When it is desired to produce but a single iushing action instead of the double one before described, the cylinder G is fastened down by the screw mias before described and as `shown in Fig. l, in which case the piston itself plays up and down, alternately coveringand uncovering the ports. The cylinder `may be removed and the piston play directly in the barrel with 'the same effect, as shown in Fig. 5; but theeleVated cup L is essential to regulate the movement ofthe piston. In some cases a small hole w, is made through `the cylinder at such position that when `the cylinder is elevated said hole will come in coincidence with the ports in the barrel, as shown in Fig. 2, in order to produce a small stream sufficient `to wet and wash the bowl when the latter is in use. This is effective `especially in iurinals.
Fig. 6 shows the Hushing attachment located below the tank `and in proximity to the bowl. In such case the piston rod I is tubular its whole length and serves as the overdow pipe. It is inclosed in `an exterior pipe R, at the bottom ot which is a casing S inclosing the barrel The regulating device consists of a separate pipe l extending fromthe pistonup through the top of the barrel and provided with the holess t aand screw c. Its action isthe same as the piston rod shown in the other figures, butas the water is fed down directly through the pipe R and in a constant supply, thecup L is not required.
