WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 725,268, dated April 14, 1903. Application fi ed October 20, 1898. Seria1No.694,108. (N model.)

Rutherford, county of Bergen, and State of New Jersey, have invented certain new and usefullmprovements in \Vater-Closets, fully described and represented in the following specification and the accompanying drawings,

forming a part of the same.

Thisinvention relates to certain improve ments in valve-controlling mechanism for the flush-tanks of water-closets.

The invention has for its object to produce an improved mechanism controlled by the seat of the closet which when the seat is released after use shall act to automatically operate the valve of the flush-tank to allow a sufficient quantity of Water to descend and fiush the basin.

A further object of the invention is to produce an improved automatic mechanism which shall eifect a slight preliminary flushing of the basin before use, such flushing being sufficient to dampen the basin, thereby preventing the adherence of fecal matter thereto.

A further object of the invention is to produce an improved valve for use in flush-tanks which after it has been operated to permit a flushing flow of water from the tank shall close gradually, thereby avoiding the slamming of the valve upon the seat and prevent ing noise and water-hammer in the pipes, and

which after it has been operated to produce a flushing flow of water shall not only automatically act to cut off the said flushing flow, but shall still operate to permit a slight subsequent. flow of water from the tank, which while not sufficient in volume to produce a flushing action shall operate as an after-fill, thereby insuring the presence of a sufficient quantity of water in the basin or the traps connected therewith, or both, to properly and effectually seal the waste-pipes.

\Vith these and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combinations,which will be hereinafter described and then specifically pointed out in the claims hereunto appended.

In the accompanying drawings,which constitute a part of this specification, and in which like reference characters indicate the same parts, Figure 1 is a vertical section through a flush-tank, showing the valve-opcrating mechanism and the connections therefor, the basin of the closet and the actuatingseat being shown in elevation. Fig. 2 is a plan view, on a somewhat larger scale than Fig. 1, of the flush-tank and the devices contained therein. Fig. 3 is a vertical section of the flush-tank, also on a somewhat larger scale than Fig. 1, the plane of section being at right angles to that of said figure. Figs. sand 5 are enlarged detail views of the mechanism for operating the valve, the parts being shown in different positions in these views. Fig. 6 is a detail plan view showing the construction by which the seat is hinged and the connection of the operating-rods to the seat. Fig. 7 is a section on the line 7 7 of Fig. 6 looking in the direction of the arrow; and Fig. 8 is a vertical central section, on an enlarged scale, taken through the valve and showing the connection of the overflow-pipe thereto.

Referring to the drawings, 1 indicates the basin of a closet of the wash-down type, and 2 indicates the seat of said basin. The seat is connected to the basin by a hinge connection of any suitable form. In order to provide for this hinge connection, the basin is provided with a hearing, which preferably consists of a perforated projection or shoulder 3, Figs. 6 and 7, which in the preferred form of the construction is integral with the basin. The seat-hinges are formed by collars 8, having suitable extensions, to which the seat is secured in any suitable or desired manner. In order to support the seat hinges or collars 8, a rod 4 is provided, which passes through the perforated shoulder 3. This rod is preferably smaller in cross-section than the diameter of the perforation and is supported in hollow sleeves or nuts 5 at opposite sides of the shoulder 3, which extend inside the perforation, with heads on the sleeves or nuts abutting against the shoulder. In the preferred form of the construction sleeves 6 are provided, which are passed over the ends of the rod land are supported thereon. These sleeves when employed are slightly larger in diameter than the rod, and therefore fit loosely thereon. These sleeves serve to support the bin ge-collars 8 of the seat. The rod 4, before referred to, also preferably serves to support an operating-arm 10, which, as will hereinafter appear, serves to effect the operation of the valve mechanism of the flushtank. This arm 10 is preferably provided with an enlargement 10, which is perforated and surrounds one of the sleeves 6 when the same are employed. "One end 10" of the arm extends under the seat, as shown in Fig. 1, so that as the seat is depressed the arm will turn upon its pivot. The arm 10 is located next to one of the hinged collars 8, and in order to produce a symmetrical appearance and also to enable the arm 10 to be located on either side of the basin, as the exigencies of the case may require, a loose ring or collar 7is placed on the rod on the side opposite to that on which the arm is located. and collar may be transposed, when desired, without trouble and without-producing an unsightly appearance. 1

In the preferred form of the construction the ends of the rod 4 are screw-threaded and are engaged by cap-nuts 11, which hold the parts securely in place. These nuts abut against the ends of the sleeves 6, and as these sleeves when 'used are slightly longer than the combined length of the hinge 8 and the width of the perforated enlargement 10 on one side and of the collar 7 and the hinge 8 on the other side the nuts can be screwed down against the ends of the sleeves, so as to hold the parts firmly in position without causing them to bind, thereby allowing the free movement of the arm and hinges on the collars.

While the construction which has just been described is the-preferred form of hinge connection, it may be varied, if desired.

Connected to the arm 10 is a rod 13, which is preferably weighted or made sufficiently heavy to act as a weight. This rod extends upward and is connected to the valve-operating mechanism for the flush-tank B. It

may be hereremarked that the flush-tank and operating mechanism therefor are shown in .Fig. 1 as concealed behinda partition A.

This partition may obviously, however, be omitted, thereby exposing the flush-tank and the operating mechanism to view.

Located upon the upper edge of one side of the flush-tank is a bracket 14, which is preferably provided with two arms projecting over the interior of the tank. An actuating-lever 15, preferably, but not necessarily, U -shaped, is pivoted between the two arms of this bracket on a short shaft 16, which is supported at each end in the bracket-arms. The actuating-lever is provided with a downward extension 17, to which the rod 13 is connected. One of the sides of the actuating-lever is formed to provide an extension 18, which The arm projects forward beyond the pivot 16. This forwardly-projecting extension 18 of the actuating-lever engages a weighted toe 19,which toe is pivoted between the arms of the bracket 14 at the forward ends thereof, the pivots being indicated at 20. This toe is further provided with a forwardly-extending projection 21, the purpose of which will be hereinafter stated.

Pivoted on the short shaft 16, before referred to, is the valve-operating lever 22, this being a lever of the third order. This lever is connected by a link 23 to the valve and passes over and normally preferably rests upon the extension 21 of the weighted toe 19, before referred to.

When the seat is depressed and the arm 10 rocked as before described, the rod 13 is given a vertical movement, and the actuating-lever is rocked on the short shaft 16. The arm 10 and rod 13, although pivoted together, form a substantially rigid connection between the seat and the actuating-lever, by which the movement of the seat is transmitted to the lever. This movement causes its forward extension to strike the inner side of the pivoted toe 19, thereby rocking it on its pivots 20. This movement causes the extension 21 of the toe to rise and carry with it the lever 22, which movement raises the valve to which the lever 22 is connected by means of the rod 23. As is apparent from the drawings, however, (see, for instance, Fig. 4,) any considerable movement of the actuating-lever will cause its extension 18 to rock the pivoted toe 19 sulficiently so that the end of the lever 18 will pass it. As soon as the end of the lever 18 has passed the toe 19 this too, being weighted, as before stated, will rock back into its original position, allowing the lever 22 to return to its normal position and the valve to close. This operation of the valve, however, has been sufficient to allow a small amount of water to escape from the flush-tank, and this water descending through the pipe 0 into the bowl gives it a preliminary wetting or dampening, so that any matter therein deposited will not readily adhere to the sides of the bowl.

The actuating lever 15 has extending through it a short rod 24, this short rod being located back of the pivotal point of the lever. Pivoted to this short rod 24. arealatch or trigger-lever 25 and a weight 26, the latch being preferably pivoted between ears on the weight 26. (See Fig. 2.) The trigger-lever or latch 25 has a forwardly-projecting shoulder 27, which in certain positions engages a shoulder 28, formed on the lever 22, and a rearwardly projecting shoulder 33, upon which the weight 26 rests.

The latch or trigger-lever 25 is connected by a slotted link 29 to the usual float 30, the said float being connected by a rod 31 to the in flow-valve, by whiclrwater is admitted into the flush-tank through the pipe 32. As the float descends said valve is operated and al- ICC I the pipe 32.

lows the water to flow into the tank through The connection between the float and the in flow-valve and the construction of said valve may be of any usual or ordinary type, and it is not, therefore, necessary to illustrate the same or describe it further.

The weight 26 is preferably provided with a shoulder 26, which is or may be engaged at times by the outer end of the actuating-lever 15. (See Figs. 4 and 5.) The actuating-lever is also provided with a downwardlyprojecting stop 34, which limits its downward movement.

When the seat is depressed, the rod 13 is given its vertical movement upward and the outer end of the actuating-lever l5 rocks upwardly, as before described. By this movement the extension 18 of the actuating-lever is caused to operate the toe 19, thus giving the valve its preliminary opening, and the outer end of the lever is pushed up into the position shown in Fig. 5. By this movement the trigger-lever 25 is carried upward to a point where its shoulder27 is above the shoulder 28 on the valve-operating lever 22. As soon as the shoulder 27 on the lever 25 clears the shoulder 28 the weight 26, operating on the shoulder 33 of. the lever 25, will swing the said lever inward and cause the shoulder 27 to engage or stand above the shoulder 28, this position of the parts being clearly shown in Fig. 5. By this movement of the trigger or latch the actuating-lever and the valve-operating lever are locked together, and since they have the same pivotal point they operate thereafter as a single lever. In other words, the latch or trigger constitutes a locking device, by the interposition of which the valve-operating lever and the actuating-lever are practically converted into a single lever,

' said lever being connected at one end to the seat and at its other endto the valve. The parts remain in the position shown in Fig. 5 so long as the seat is maintained in its depressedposition. When,however,theWeight is removed from the seat, the weighted rod 13 will descend, carrying with it the actuatinglever 15, which, so far as the work done by it on the operating-lever, is a lever of the second order. Since the trigger or latch is mounted in the actuating-lever, and by reason of the fact that its shoulder27 has engaged the shoultuating-lever will continue until its stop 34 strikes the bracket 14, to which the lever is pivoted, by which movement of the parts the valve is raised to its full extent, and the water is allowed to escape from the flush-tank down through the pipe 0, thereby flushing the closet. As the water escapes from the closet the float 3O descends. The position of the various parts of the valve-operating mechanism remains as above described until the rod 31 strikes the bottom of the slot in the link 29, which connects the lever 25 to the float. When the float has reached this position, its further downward movement operates through the link 29 to pull the triggerlever downward and backward, thereby releasing its shoulder 27 from its engagement with the shoulder 28 on the lever 22. As soon as this occurs the valve is free to close, and does so, the lever 22 resuming the position shown in Fig. 4, with its shoulder28 'above the shoulder 27 of the trigger-lever25.

The parts now being in their norm'al condition are ready to be again operated in the manner before described to flush the closet, as before described.

It is of course understood that the descent of the float 30 opens the inflow-valve of the flush-tank and that the tank has become filled through the pipe 32.

\Vhile the apparatus before described may be used with any desired form of valve, the valve is preferably constructed so that its movement in closing will be automatically controlled, so as to avoid noise and any slamming of the valve against the seat, and also the construction of the valve is preferably such as to provide for a slight flow of water after the flushing action proper has ceased, thereby providing for an after fill and insuring that sufficient water to form a proper seal flows into the basin or traps, or both. To accomplish these objects, the valve is preferably constructed as follows: A casing 35 is provided, which carries valve-seat 36. valve-seat 36 is surrounded by the ring 37, which engages suitable threads formed on the outer portion of the upward projection on which the valve-seat is formed. Two legs or extensions 38 connect the ring 37 to an upper annular chamber or casing 39. The bottom of the chamber 39 is formed by a web 40, having an upward projection 41, into which is screwed or to which is otherwise secured an upwardly-extending tube 42. The casing 39, the web 40, and the upwardly-extending tube 42 form an annular chamber the top of which is below the normal level of the water in the flush-tank and which is therefore filled with water.

43 indicates a leather or elastic plate forming part of the valve proper, which plate rests upon the valve-seat 36. This plate 43 lies between washers 44 45. A shouldered collar 46 bears against the washer 45. The plate 43, the washers 44 45, and the collar 46 fit somewhat loosely on a rod 48, which forms the valve-stem. The collar 46 is engaged by a shouldered nut 47, which is screwed upon the lower end of the valve-stem 48. Surrounding the stem 48 and bearing against the The IIO

' 52, and to this shoulder is connected a threaded tube 53. This tube has secured to its lower end, by means of a thread or in any other suitable manner, a plate 54, which plate is somewhat less in diameter than the annular casing 39. Lying below the plate 54 is a second perforated plate or annulus 55, which surrounds the upwardly-extending threadedportion of the bottom 40, the diameter of its central opening being somewhat greater than the diameter of said upwardly-projecting extension. This perforated plate or annulus is nearly as large as the diameter of the casing 39, but is of a sufficient size to work freely therein, and it is loosely connected in any suitable manner, as by headed bolts 56, to the plate 54, it being free to play up and downon the bolts. It being remembered that the casing 39 is normally filled with water, it will be seen that when the valve is raised by means of the valve-operating mechanism before described the plate 54 and the annulus 55 will be carried upward in the chamber 39, and the annulus will by the action of the water in the casing be forced downward against the heads of the bolts 56. The water in the casing will therefore flow between the plate and the annulus and through the opening in the center of the annulus and between it and the upwardly-projecting tube 42 into the lower part of the casing. A portion of the water which is contained in the casing may be forced out over its upper edge by the upward movement of the plate and the annulus; but should this occur inasmuch as the top of the casing is located somewhat below the normal level of the water in the tank as soon as the upward movement of the plate and annulus has ceased sufficient water will run in to fill the casing. When the valve-operating mechanism is released, as before described, the valve is free to seat itself. The first movement of the valve in the downward direction will cause the annulus 58 to be forced upward against the plate 54. The plate54 will now act to close the opening between the annulus and the tube 42, and the Water which is in the casing will act as a cushion and resist the downward movement of the valve. The valve, therefore, can move downwardly only so fast as the escaping water will permit, and as the water can only escape around the edges of the annulus 55 and between it and the sides of the casing 39 the downward movement of the valve will necessarily be slow, thereby avoiding-any sudden closing or slamming of the valve.

The valve-seat 36 is provided with a series of inwardly-extending studs 57. These studs act to support an annulus 58, which is carried by the valve and which is free to move between the shoulder on the collar 46 and the shoulder on the nut 47. As the valve is raised the annulus 58 will be carried forward clear of the opening through the valve-seat and allow an unobstructed flow of water into the pipe 0. When, however, the valve starts to move in its downward direction, as soon as the annulus 58 reaches its supporting-pins 57 it will be stopped by them. It will at this time, therefore, act to partially close the opening through the valve-seat and so diminish the flow of water as to cause the flushing action to cease. \Vater will still continue to flow around this annulus in a diminished quantity until the valve proper comes to place on its seat, and this afterflow, while not sufficient to cause a flushing action, properly so called, will act to fill the basin or trap, orboth, and so insure a proper water seal.

The casing 35 is provided with a lateral hollow extension 35, to which is secured an upwardly-extending overflow-pipe 59.

Various modifications may be made in the mechanism, and various parts are capable of use independently of the other parts and in relations other than that herein set forth.

For instance, the actuating-lever 15 may be made straight instead of U shaped. The weight 26 may be omitted altogether and the latch itself Weighted in such a manner that it will of itself engage the valve-operating lever. The connections between the seat and the actuating-lever may be varied, and in general many other obvious modifications, which it is not necessary to specifically state, may be made. The invention is not, therefore, to be limited to the specific details of construction herein described, but is to be regarded as generic in its nature and as including all modifications which come within its spirit and scope.
