WILLIAM SYDNEY GRAHAM, OF CHICAGO, ILLINOIS, ASSIGNOR TO FEDERAL-HUBER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
CLOSET-FLUSI-II'NG APPARATUS.
T 0 all'who'm it may concern:
Be. it known that I, WILLIAM SYDNEYv GRAHAM, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Closet- Flushing Apparatus; and I do, hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a novel construction in seat operated flushing mechanism for tion showing a modified form of construction whereby the connection between the bowl and the flush tank is made at the rear of the bowl. Fig. 4 is a fragmentary detail section showing a modified form of construction of the connection between the valve actuating mechanism and the closet seat whereby the tension of the springs supporting the latter may be easily adjusted. Said section being on the plane indicated by the section line 4--t of Fig. 3. Fig. 5 is a detail section on the line 5-5 of Fig. 4, showing the means employed for adjusting the tension of the seat supporting springs.
My invention relates particularly to valve mechanism for that class of flushing apparatus in which the water under pressure is introduced into a hermetically sealed flush tank compressing the contained air in the latter so that upon opening the discharge valve the contents of the tank'are ejected at corresponding pressure, that is to say, the initial pressure of discharge would be equal to the service pressure and such pressure would gradually decrease in accordance with the expansion of the air.
Specification of Letters Patent.
Application filed September 28, 1908.
Patented Sept. 13, 1910. Serial No. 455,178.
The main object of my invention is to provide simple valve-mechanism controlled and actuated by the closet-seat, which, when the latter is depressed, will open the valve controlling the service pipe and close the discharge valve of the tank, thereby connecting the service pipe with the tank and cutting off flow to the bowl, and Which, when the seat is released, will permit the supply valve to the tank to close and simultaneously open the flush valve, thereby causing the water contained in the tank to be ejected into the bowl. A further object of my invention is to provide suitable means for permitting proper adjustment of the operating parts of the device and to so construct the device as to permit ease of disassembling for purposes of adjustment and repair.
This invention consists particularly in the relative arrangement and disposition of the valves and the means operating the same whereby all of said mechanism is enabled to be disposed in a casing mounted upon the closet bowl, and in so constructing the de vice as to render assembling and disassembling easy and rapid of accomplishment.
The invention consists further in the means provided for securing the device firmly upon the closetbowl in such a manner as to provide a fluid tight joint between the same.
Referring now to said drawings, (1) indicates a valve casing, centrally of which is a hollow cylindrical tube (2). connected by means of a lateral passage (3) with the service pipe, the mouth of said passage consisting of an externally threaded flange (4;) projecting laterally from the casing. In the lower end portion of said cylinder (2) is an inwardly extending annular flange (5) constituting a valve seat, upon which the valve (6) seats. In the upper end portion of said cylindrical tube is a cap (7) threaded therein and which is provided with a central recess (8) in which the upper end of a compression spring (9) is held, said spring serving to maintain the valve (6) normally closed.
The valve (6) is disposed upon the upper end of a skeleton stem (10), which at its lower end terminates in a tapered valve (11) seating upon the valve seat (12) formed by the annular shoulder at the lower end of the casing (1) projecting inwardly of the in said valve (11) is a set screw (17), upon which the free end portion of a lever (18) is adapted to bear, said lever being loosely mounted upon a shaft (19) passing laterally through said casing (14). The hub portion (20) of said lever (18) is provided with a segmental recess (21) communicating with the opening therein through which the said shaft (19) passes, and in said recess (21) a projection (22) of said shaft (19) is adapted to move, said projection being adapted to engage the end wall (23) of the said segmental recess when said shaft is turned in a direction to turn said lever in a direction to raise said valves (11) and (6). The said shaft (19) projects at its ends beyond the side walls of said casing (14), the same passin through what may be termed an arm 24) of said casing. The latter is provided in its side walls with threaded openings of larger diameter than said shaft (19) which receives removable bearing (25) in which said shaft (19) is journaled. Each of said bearings (25) is provided with an annular flange (26) which is cut away internally at its free end portion to receive the inner end of the annular flange (27) of a sleeve (28) secured upon the free end of the shaft (19) by means of a set screw (29), said sleeve (28) being integral with the hinge (30) secured to the closet-seat. In the bottoms of the annular recesses (31) of the bearings (25) and the recesses (32) of said sleeves (28) are openings (33) and (34) respectively in which the opposite ends of the spiral springs (35) are received. Said springs serve to normally maintain the closet-seat elevated in a well known manner. The said casing (14) may be secured to the closet-bowl by means of bolts passing through openings in a flange (36) to which said casing, may be secured, and also by means of an expansion washer (37) compressed against the wall of the flush opening (38) of the bowl, said washer being compressed between an annular flange (39) on the base of said casing (14) and the annular flange (40) of a threaded sleeve (41),
which engages a threaded annular flange (42) disposed concentric with and inwardly of the flange (39) and which also is integral with said casing (14).
The flush tank before referred to is so well known that illustration thereof is deemed unnecessary. Y
The operation'of my device is as follows: The closet-seat is normally maintained elevated to substantially vertical position and when depressed against the action of said springs (35) does not during its initial downward movement actuate the valve mechanism, but when depressed to an incline of fifteen or twenty degrees above'horizontal the projection (22) of the shaft (19) engages the end wall (23) of the segmental recess (21) of the lever (18) thereby raising the free end portion of said lever. By the engagement of the latter with the head of said set screw (17 the valves (11) and (6) are raised against the action of the spring 9), the valve (6) opening and the valve 11) closing, thereby shutting off communication between the tank and said casing (14), and at the same time establishing communication between said tank and the service pipe. Water now enters the casing (1) through the opening controlled by the valve (6) and passes upwardly around the cylinder (2) into the tankcompressing the air therein in a well known and obvious man.- ner. I The flow from the service pipe into the tank will obviously cease the moment the pressure in said tank equals, the service pressure. As soon as the seat is released the springs (35) will obviously raise the latter, this action 'being accelerated by the spring (9) and the service pressure, thereby causing the valve (6) 'to close and the valve (11) to open, whereupon the contents of the tank will be ejected through the casing (14) into the closet-bowl. V g
In order to effect repairs such as replacing the rubber disks of the valve and the valve seat (12) it is only necessary to separate the casings (1) and (14), whereupon access may easily be had to all parts of the valve mechanism. The parts connected with the shaft (19) are likewise easily accessible and easily adjusted, such adjustment being primarily effected by removing the hinges from the closet-seat loosening the screws (29) and removing the sleeves (28). The position of the springs (35) with relation to the bearin s (25) may then be adjusted as desired, an in replacing said sleeves (28) the hinge leaves may, if desired, be turned to extend vertically above said sleeves, or
even at an incline 'toward the casing (1),
and when the ends of the springs (35) have been received in openings ('34) in said sleeves (28), the set screws- ('29) are turned to secure said sleeves against rotation on the shaft (19). The closetfseat is then securedto said hinges and the device is then ready for-operation. 1 I
In Fig. 3 I have illustrated a modified form of construction showing an elbow outlet or horn (43) on the casing (14) which is necessary to effect a connection with the rear of a closet bowl, and in addition thereto I have shown a modified form of construction of expansion joint between the said horn or elbow and the wall of the opening in the bowl receiving the same. At its free end said horn (43) is provided with an internally tapered flange (44) which is ofl'set annularly inwardly to provide an annular recess in which the gasket (45) of rubber or the like is received. The said flange (44) is longitudinally split at intervals to render the same expansible and receives the externally tapered flange (46), of a ring (47) equipped with a hub (48) having a central, threaded opening, said hub being supported on the arms or spokes (49) integral therewith. A bolt (50) passing loosely through an opening in the end wall of the horn (43) enters the said threaded opening in the hub (48) and serves when turned in one direction to draw the said tapered flange (46) into the tapered flange (44) to expand the latter thereby expanding the gasket (45) against the wall of the opening in the bowl.
In the construction illustrated in Fig. it will be observed that in order to effect adjustment of the springs (35) to a tension suflicient to support the closet-seat in its vertical position it is necessary to remove the said seat from the hinges. This is very inconvenient, and I prefer, therefore, to employ the construction shown in Fig. 4 in which sleeves (51) are rotatably mounted on the shaft (19) between the bearings (25) and the sleeves ('28) at the ends of the hinges (30), said sleeves (51) being received in the annular recesses, between the annular flanges (52) of the bearings (25) and the shaft Each of said sleeves (51) is provided in one end with an annular recess (53) in the bottom of which a plurality of recesses (54) are provided to receive one end of the springs (35), the other ends of the latter being received in the recesses (34) in the sleeves (28) of the hinges (30) as previously described. Said sleeves are provided on their exposed end portions with polygonal surfaces to re ceive a wrench in a well-known manner requiring no illustration, thus enabling the tension of the springs to be adjusted by turning said sleeves (51). The latter are provided with peripheral openings to receive the ends of set-screws (55) disposed in threaded openings in the flanges said set-screws serving to hold said sleeves against rotation relatively to said bearings. This construction confers many advantages over the construction shown in Fig. 2, not only with regard to ease of adjustment, but also with regard to the necessity of loosening the set-screws (29).
My device is neat and compact, otters all necessary or desirable latitude of adjustment at all points and obviates the necessity ofusing heavy springs at any point, the use of the latter being particularly undesirable by reason of the greater strains on. certain parts and also their liability to wear out faster. For example, the fact that the valve (6) closes with the pressure enables a very light spring to be employed to normally maintain said valve closed, and the use of two light springs to support the closetseat instead of one heavy spring distributes strain and decreases wear and tear. The means provided for adjusting the tension of the last-named springs is also advantageous as it enables the normal angle of support of the seat to be adjusted as desired and also enables any weakening of the springs to be taken up, thus obviating the necessity of providing new springs at as frequent intervals as would be necessary were the adjusting means omitted.
