SPECIFICATION forming part of Letters Patent No. 519,337, dated May 8, 1894.

Application filed November 13, 1893- Serial No. 490,754:- (No model.)

To all whom it may concern:

Be it known that I, JOHN MOLONEY, Jr., of V the city and county of Philadelphia and State of Pennsylvania, have invented an Improve ment in Flushing-Tanks, of which the following is a specification. v

My invention relates to flushing tanks for water closets, and consists of certain improvements which are fully set forth in the followto ing specification and are shown in the accompanying drawings.

The particular object of my invention is to provide a flushing tank with capacity for au-. tomatically performing an additional or sec [5 0nd flushing or afterwash of good head and volume, so that, whenever the basin is flushed, a second flushing or afterwash takes place automatically, thereby keeping the basin clean at all times and effectively carryingoffthe refuse. The mechanism which I employ is of such a character that whenever the chain or cord is pulled to produce the first flushing or washing of the basin, the second flushing or afterwash follows automatically 2 5 as a matter of necessity. Even if the chain be pulled at a time when the tank is empty, or partially empty, so that the water does not immediately flow, the mechanism is brought into such a position that the first flushing and afterwash result from such pulling of the chain as soon as the tank becomes filled. The operation of the apparatus is therefore certain and the basin of the closet will always be kept clean.

3 5 I shall now refer to the accompanying drawings for the purpose of more particularly describing my invention.

Figure 1 is a side elevation of my improved flushing apparatus with the tank in section.

4.0 Fig. 2 is a similar view showing the apparatus operated to discharge the contents of the tank. Fig. 3 is an illustrative view showing the apparatus provided with an automatic seat connection. Fig. 4 is a transverse vertical sectional view of the apparatus on the line a:-w of Fig. 1. Figs. 5 and 6 are perspective views of details for controlling the afterwash or second flushing.

A is a tank of usual construction.

B is an outlet pipe leading to the basin 0 the closethaving its outlet 1) controlled by a valve 0.

D is a water inlet, for supplying water to the tank, having a valve E. The outlet pipe B may be extended in the I usual manner to the normal high water line so as to form an overflow outlet provided with a float valve 13.

F is an automatically actuated lever. This lever is preferably of the construction shown being fulcrumed as at f to a bracket or support F, and having one arm weighted as at F The other arm of the lever F is connected by intermediate connections with the valve 0. In the drawings these connections are shown as follows: Alink Gconnects the outer end of the lever F witha short arm g of a pivot pin G, journaled in suitable supports b, preferably on the pipe B. A rocking frame or arm H is journaled on the pin G and hinged as at h to the valve 0. The upper end of the rocking arm or frame above the journal is provided with two pins or lugs c, c between which extends an arm Icarried by the pin G or crank arm 9 so as to move with it.

J is a counter weight carried by an extension J of the rocking frame or arm 1-1. When the lever F rocks on its pivot f under the action of the weight F it raises the arm g through the link G, and thus rocks the arm or extension I and causes it to strike the pin or lug o and thus rocks the arm H on the pin G opening the valve 0. The counterweight J tends to throw the valve fully open when the arm II has been actuated. When the lever F is moved in the opposite direction, it causes the arm I to strike the pin a and thus closes the valve 0.

K is a lock controller preferably constructed as a ratchet wheel suitably journaled in the tank A and provided with pins or lugs k.

L is a dog carried by the lever F and engaging the pins or lugs is so as to actuate the lock controlling ratchet wheel K.

M is a lock, preferably constructed as. a lever fulcrumed as at m to the tank and having its free end sustained by the logs or pins k.

The pins or lugs k are so arranged that at intervals they are omitted, so that when the end of the lock M is. in a position where the lugs or pins are omitted, it will fall.

The lever F is provided with a lug or pin N and the lever M is provided with a notch 'n adapted to engage the lug N on the lever yico pins or lugs the periphery of the controller K may be suitably notched or recessed and the end of the lever M may rest upon such notched or'recessed periphery. These two constructions are obvious equivalents. The

outer end of the lock M is connected withthe chain or cord 0 whereby the lever M may be positively actuated to unlock the lever F.

P is a float lever fulcrumed as at p in a bracket P and carrying the float Q upon its outer end.

R is a link connecting the float lever Q with the inlet valve E in the well known manner.

S is a link connected at one end with a lock or leverT which is fulcrumed as at f and connected at the other end with a pin d upon the float lever P, whereby the float lever is adapted to actuate the lock '1 and lift it when the float lever is elevated. The lock T is provided with a notch 8 adapted when the lever is depressed into its lowest position to engage a lug g on the arm I to lock the arm and lever F out of action. If desired the relative positions of the notch s and lug q may bereversed.

U is a pawl to prevent backward rotation of the controller or wheel K.

Ishall now describe the operation of the apparatus: Normally when the tank is full the parts are in the positions shown in Fig. 1, the float lever P in its highest position, the lever F raised and locked by the lock M with its free end resting in a depression in the periphery of the wheel K or in a tooth denuded space therein and the valve 0 closed. To operate the apparatus the chain or cord 0 is pulled, this raises the outer end of thelock M so as to disengage the lugN from the'notch 'n. The lever F being thus unlocked rocks under the action of its weight F elevating its outer end and opening the valve 0 through the link G, crank g, arm I and frame II in the manner heretofore described. As the lever F rocks the dog L turns the wheel K so as to bring a pin 75, or raised portion of the wheel, under the end of the lock M. The lock M is thus held in araised position so that its notch n cannot re-engage the lug N of the lever F. When the valve 0 is opened the water flows through'the outlet 1) and pipeB to the closet. This is the first flushing operation. As the water in the tank flows out, the float Q and its lever P descend and the lever P strikes the joint of the lever F with the link G, thereby depressing the lever and link and rocking the arm 9 and its extension I. The extension I when thus'rocked strikes the lug c of the frame H and'closes the valve 0. At the same time the lever P descending on the link S strikes the end of the lock T and depresses when the lock T it so that the notch s engages the lug q of the extension I thus locking the valveOshut and preventing it from being operated by the lever F. The parts are shown in this position in dotted lines in Fig. 1. The Water flows into the tank from the now opened valve E causing the float Q and its lever P to rise. When the leverP is elevated the pin 01 reaches the end of the slot in the link S and raises the link sufliciently to lift the lock T from engagement with the arm I. The valve 0 and lever F are then unlocked so that the weight F rocks the lever F and opens the valve 0 in the same manner as has been previously described. The water again passes out through the outlet b and the second flushing or afterwash takes place. As the lever F rocks, its dog L turns the wheel K the distance of another tooth, this time bringing a tooth denuded or depressed portion of the wheel K under the end of thelock M, so thatwhen the lever F is again elevated by the action ofthe descending lever F in the manner described it is engaged and locked by the lock M. When the locking lever T is now lifted from engagement with the arm I the afterwash does not take place, since the lever F is locked, but the tank remains full with the parts in their original position ready to be operated by the pulling of the cord or chain attached to the lock M. There should be sui'ficient playin the connections between the end of the lever F and the valve 0 to permit the lever F when released by the lock M to move slightly, even is engaged with the arm I, so that, even if the lock M is operated after an afterwash has taken place and the tank is empty, the slight movement permitted in the lever F by this loose play will be-sufficient to prevent the re-engagement of the lever F by the lock M when the chain 0 is released. Consequently the lever F remains unlocked by the lever or look M and will operate under the influence of the weight F as soon as the water in the tank has reached a sufficient level to cause the float lever P to raise the lock T. Then the wash and afterwash proceed regularly.

I have described the operation of the apparatus with a single afterwash. It is apparent that by a proper arrangement of the depressions or pins for controlling the lock M several afterwashes may be obtained from a single operation ofthe lever M by the chain or cord. The afterwash it will be observed may be made with the full contents of the tank. An afterwash with less than the full contents of the tank may be produced by shortening the length of the slot of the link S so that the lock T will be disengaged before the float lever P has beenfully elevated.

In Fig. 3 I have shownthe apparatus adapted to an automatically operating closet seat V having connection W with the lever M. With such a construction as this, however, as the tank continues to empty as fast as it is filled, so long as the seat is occupied, the afterwash attachmentis not usually necessary. I

The joint of the lever]? with the link G may be provided with an antifriction roller G to receive the contact of the lever P.

The minor details of construction shown may be varied without departing from the invention.

What; I claim as new, and desire to secure by Letters Patent, is
