FLUSHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 649,670, dated May 1 5, 1900. Application filed June 25,1898. Serial No. 684,469. (No moclelh To @ZZ 1071/0721, zit may concer/z:

Be it known that l, EPPIE J. MCCULLOCH, of Manchester, county of Hillsborough, and State of New Hampshire, have invented an Improvement in Flushing Apparatus, of which the following description, in connection with the accompanying drawings,isaspecication, like letters on the drawings representing like parts.

The present invention relates to a flushing apparatus, and is mainly intended for use in places where the flushing-tank, supply-pipe, dsc., are liable to be exposed to extreme cold, the object of the invention being to obviate the trouble and damage due to freezing.

In the apparatus embodying the invention the tank is arranged to be normally empty and is filled and discharged at each flushing operation, the supply-pipe being controlled by a valve below the surface of the floor or ground or at any other place where the water is not liable to freeze. The said valve is arranged with a by-pass or drain-opening, so that when the valve is closed the water in the supply-pipe will drain out and leave the said pipeempty, the service-pipe also being arranged so that all the water is drained out of the tank in the flushing operation, and the tank and all the pipes leading therefrom are therefore normally empty.

The invention further consists in novel operating mechanism for controlling the flushing operation, the said mechanism being so arranged that a manual or automatic operation, as the case may be, opens the supplyvalve, causing the tank to ll, the flushingvalve, however, being closed as the supplyvalve is opened and remaining closed until the tank is lled to the desired level for the flushing operation. The opening of the flushingvalve is automatically controlled bya device adapted to operate in response to the rise of water in the tank-such, for example, as a float-and the action of the said automatic device is such as to open the flushing-valve and close the supply-valve at the same operation, The water then passes through the service-pipe and also drains out through the supply-pipe, the latter, however, being of relatively-small capacity, so that it does not materially interfere with the fhiishing operation, although it empties itself during or after such flushing operation.

The valve operating mechanism, which may be controlled, as stated, either by a manual actuating device or an automatic actuating device, comprises a pivotally-supported or rotatable member connected at a point radial to its pivotal support or axis with the supply-valve, so that when it is moved upon said pivotal support itwill open the said valve, at the same time bringing the line of connection between it and the valve across its own axis or center, so that the said valve will remain open until the said point of connection is moved back far enough to throw the line of connection across or out of line with said center. The said operating device is provided with a projection arranged to coperate with a cam-surface formed on a lever which controls the flushing-valve, whereby the same movement which opens the supply valve will close the said flushingvalve. To open the ushing-valve and close the supply-valve, said ilushing-valve lever is arranged to be acted upon by a device which is adapted to operate in response to the rise of water in the tank, the said device lifting the said lever, and thereby acting upon the projection from the operating member and moving the same upon its axis far enough to carry the line of connection between it and the supply-valve across its axis, said supply-valve being arranged to close automatically, as by a spring, as soon as it is free to do so.

The invention further relates to au automatic seat-actuating device of novel construction and arrangement.

Figure 1 is a front elevation, partly in section, of a flushing apparatus embodying the invention. Fig. 2 is a side elevation of thc same, also partly in section; and Fig. 3 is a dctail showing the operating member set.

In Fig. l of the drawings a manual actuating device is shown in addition to the novel automatic actuating device which forms a feature of the invention, it being understood, however, that in practice but one of these devices would be used and the other dispensed with.

The tank a communicates through the serv- IOO ice-pipe a2 with the bowl as, the floor or inner surface of the tank being inclined from the sides toward the point where the servicepipe communicates therewith, so that at each A the closet is situated in a cellar, or at any other point where there is practically no liability of encountering temperature below the freezing-point. The said valve b2 is provided with a by-pass or drain-opening b3, arranged to let the water out of the pipe b when the said valve b2 is closed, it being understood that any suitable or usual by-pass valve may be employed-such, for example, as that shown and described in Patent No. 502,563, to JNV. Hill, dated August 1, 1893. The construction of said valve is not herein shown, since it forms no part of the present invention, it being,in fact,immaterial what specific form of valve is used. The said valve b2 is normally closed and the flushing-valve c, which controls the ow of water from the tank to the service-pipe a2, is normally open, so that the tank and all the pipes above the floor or ground are normally empty. The drain opening or pipe Z13 may be arranged to communicate with the main drain-,pipe or the closet-trap, the connection not being herein shown, since it is immaterial to the invention. To produce the iiushing operation, therefore, it is necessary to open the valve bzand at the same time to close the valve c in order that .the tank may fill until there is a sufficient supply of water therein to properly flush the bowl. To this end the said valves are provided with a common operating device d, the initial operation of which is under the control of a suitable actuating device, such as the handle e, connected therewith bya chain e2, passing over a pullejT es, or by an automatic seat-actuating device of novel construction, which will be hereinafter described. The said operatin g member d is pivotally supported upon a suitable bracket d2 and is shown as in the form of a disk capable of osthe chain e2 being connected to said disk at or near the periphery thereof, so that pulling the chain causes the oscillation of the disk. As shown in Fig. 2, the said chain lies in a groove along the .periphery of the member d and is fastened at a point some distance beyond the point where it normally leaves the periphery of said member, so that a pull on the chain will rotate or rock the member suficiently far to cause the proper operative vmovement ofthe parts connected with and operated by said member. To open the valve b2, therefore, the said member cl is connected at d3 with a chain d4, passing over pulleys d5 and connected with a lever or other actuating member b4, arranged to open the valve b2.

The member d being pivotally supported orl arranged to oscillate around a fixed axis, it is obvious that the point d3 will travel on the arc of a circle from the position shown in Fig. l to that shown in Fig. 3, and in so doing will move upward, and thereby act upon the lever c4. As soon as the point da reaches such a position that the chain d4 has crossed the axis of the disk Fig. 3 the valve b2 (which is arranged to close automatically when not held open) will be prevented from so closing if the further movement of the disk is prevented lafter the chain d4 has crossed the center.

Such movement being prevented, as will be hereinafter described, the supply-valve will remain open and the water will begin to flow into the tank. In order, however, that the tank may become charged with water prior to the actual iiushing of the bowl, it is necessary to close the valve c, the said valve being herein shown as a tubular plug having an annular valve seat c2 arranged to cooperate with a corresponding valve-seat C20 in the bottom of the tank, the said valve-seat being wholly below the sloping bottom of said tank, so that perfect drainage is secured when the said valve is open. The said valve c is longitudinally movable in a tubular guide c3 and is arranged to be controlled by the action of the lever c4, which extends into an opening c5, which opening mayalso serve as an overflow in case the valve c should accidentally remain closed after the tank is filled to the proper level. The said lever c4 is also under the control of the operating device CZ, which has a projection d6 arranged to coperate with the lever c", which is shown as pivoted at c6 in suitable lugs supported by the tank a. The projection (ZG will obviously travel on the arc of a circle around the axis or pivotal support of the member d, and in so traveling is arranged to engage a cam-surface c7 of the lever c4, so that it will cause the said lever to rock on its pivot and either positively lower the valve c or permit the same to drop of its own weight, the latter method being preferable and such method beingindicated, as the lever is shown as loosely inserted into the opening c5 to positively lift, but not necessarily,T to posi- I tively lower, the said valve. cillating or rotating on said pivotal support,

The cam-surface c7 is preferably formed by making a slot in the end of the lever c4, the

opposite surface of said slot also forming a cam o8 to be acted upon by a movement of the member cl in the opposite direction,which will therefore result in thelifting of the valve c. Furthermore, at the end of the said slot the surface o9 may be utilized as constituting a stop for the member d to prevent the same from turning beyond a certain point in response to the action of the valve b2.

As will be seen from the foregoing description, the movement of the member d in response to a pull upon the chain e2 will open the valve b2 and cause the projection d to travel along the slot in the lever c4 until it IOC IIO

brings up against thesurface 09, at which time the chain d* has crossed the axis of the member d, so that the tendency of the valve h2 to close will act to retain the parts in said position. rlhe water then begins to flow into the tank, being retained therein as the tank fills owing to the closure of the valve c. In other words, the initial movement of the actuator sets the operating device, so to speak, the said operating device being provided with automatic restoring means of any suitable kind, the self-closing valve b2 being shown as utilized for this purpose, and as soon as the operating device d is thus set the tank begins to fill. To obtain the actual ilushing of the bowl, therefore7 it is essential to open the valve c at the proper time, this being accomplished automatically by tripping or releasing the operating device CZ and permitting the same to return to its normal position. To this end the lever c4 is arranged to be acted upon by a device which operates in response to the rise of water in the tank, such device being herein shown as a float f, mounted on an arm pivotally supported at f2, the said arm being arranged to engage the lever c4 as the oat rises. For this purpose the said arm is shown as provided with a projection f3, arranged to engage the under side of the lever c4 and rock the same on its pivot, thus depressing the end of the lever which cooperates with the operating device d. In this operation the projection ci is acted upon by the surface c?, thus causing the member d to move on its axis, aslight movement being sufficient to throw the point d3 and chain d4 out of line with the axis of the member d, so that the pull upon the chain d4 caused by the action of the self-closing valve b2 or otherwise will continue the movement of the member d until the parts are restored to their normal position. Such movement of the member d acts, through the agency of the projection do, upon the lever c4, thus lifting the valve c, the parts then being held in their normal positions, as shown.

It will be seen from the foregoing description that the tank and pipes are normally empty and that the tank fills and discharges in response to the actuating device, thus securing uniformity in the iinshing operations and insuring an ample supply of water each time.

As has already been stated, the device is capable of being automatically operated through the action of the seat when such action is preferred to the ordinary pull-chain e2, which has been hereinbefore described.

As herein shown, the seat g is arranged to coperate with a rod h, which acts upon a chain t', which may be connected with theA member d, near the periphery thereof, so that a pull upon the said chain will produce the same operation as .that already described in conjunction with the chain e2.

It is necessary that the flushing operation should take place in response to the release of the seat after it has been depressed, and

consequently the said seat is so arranged that the depression thereof merely sets the parts in condition to operate, the seat being shown as operating upon a lever-arm g2, provided wit'h a roll g3, the said lever-arm being pivoted at g4 and provided with a weight. g5, which normally holds the parts in the position shown. The said lever-arm is shown as provided with a projection g, which is connected with the rod h, so that when the seat is depressed the said rod 7L is lifted and becomes connected with the chain i, so that when the weight g drops the chain will be pulled and the operating member d moved to start the fiushing operation.

To connect the rod 7L with the chain t', the said rod is shown as provided at its upper end with a hook member h2, arranged to co operate with a corresponding hook member t2, which is connected with the chain i, (see Fig. 2,) the said hook members being supported in a guide 7i: and arranged to latch together upon the lifting of the rod h. To cause the hook h2 to come into proper engagement with the hook i2, the former is shown as provided with a spring h3, which acts against the wall of the guide 7c, tending to move said hook 71,2 toward the hook i2, so that it will engage the same as soon as it has passed by. rlhe two hook members being thus in engagement, it is obvious that when the Weight falls the member t2 and chain 't' will be pulled down, thus causing Ithe supply-valve to open and the flushing-valve to close, as hereinbefore described. It is essential, however, in order to complete the operation that the chain should not be prevented from moving back to its normal position when the operating member d is acted upon by the rise of the iioat f. For this purpose the hook members Wand Q12 are ar ranged to become automatically disengaged from each other as the rod h moves downward, the disengagement taking place as soon as the member d has become set, so to speak, to s tart the filling operation.

As herein shown, the hook member h2 is arranged to cooperate with the cam-surface 7a2 in one wall of the guide lo, the action being such that the said member h2 is moved out of engagement with the member ft2, as illustrated in Fig. 2.

It will be seen from the foregoing descripM tion that the iiushing apparatus embodying the invention cannot be rendered inoperative by freezing when the temperature in the room in which it is situated falls belor the freezing-point. After each iiushing operation the tank and pipes are fully drained, and it will be noted, moreover, that the guide for the iiushing-valve is wholly above `the normal level of the water in the tank, so that IOO IIC)

no water can remain between it and the valve herein shown and described, since obvious modifications may be made Without departing from the invention.
