AfrnNr SPECIFICATION forming part of Letters Patent No. 440,755, dated November 18, 1890. Application tiled July l1, 1888. Serial No. 279,618. (No model.)

To @ZZ whom, t may concern:

Be it known that I, HUGH H. CRAIG-1E. of Stamford, Fairfield county, Connecticut, have invented certain new and useful Improvements in Hopper Vater-Closets, of which the following is a specification.

This invention relates more particularly to the class of closets known in the trade as swing-seat hoppers,77 but is in part applicable also to other kinds of closets. The invention pertains in part to the construction by which the valve is made to discharge water into the bowl, in part to means for operating the valve from the seat, and in part to means for counterweighting the seat in order that when the closet is not in use the seat shall swing up.

The water-closet bowl, which may be an iron bowl connected with a short trap, according to the construction well known as applied to short-hopper closets, is constructed with a flushing rim or fan at its top and with an exterior chamber or pocket or large hollow lug at one side, the interior of which chamber communicates through asuitable passage or opening with the interior of the bowl, near the top thereof, so that the flushing-water discharged into said chamber will flow therefrom into the bowl and be directed into the Hushing-rim or against the fan, as the case may be. The iiushing-water is admitted through a self-closing valve of the class known to the trade as a variable chamber-valve. This valve is coupled to the said exterior chamber, and is constructed to discharge the water inside of said chamber, while its stem passes out through the top of t-he chamberin order to be acted upon by the seat or other means for operating it. Thus any water that may leak past the usual packing around the stem will be discharged within the chamber and dow thence into the bowl. In the preferred construction the chamber is divided into two portions or compartments by means of a diaphragm, the lower compartment receiving the water flowing from the valve through its outlet and conducting this water into the bowl, while the upper compartment serves to receive any leakage from around the valve-stem and to conduct it also to the bowl. Preferably the two compartments are divided by a diaphragm consisting of a removable Fig. 2.

plate, by the removal of which access may be gained to the lower compartment, and preferably, also, this plate is extended into the bowl and turned downwardly therein opposite the inlet opening or compartmentin order to form a fan for delecting the entering flushing-water.

In the case of a swing-seat hopper the valve may be placed at one side, so that the seat, when it is pressed down, shall force in the valve-stem and operate the valve. In the preferred construction, however, the valve is placed at the back, and is operated from the seat through the medium of au interposed lever.

The seat is eounterweighted by means of two separate weights rigidly attached to its hinge-plate by screws and bolts or otherwise, so that they may be removed when a seat that is not counterweighted is desired. The two weights are separated far enough to leave space between them for the flushing-valve, or (in case of a closet that'is operated from an overhead tank) for the pipe by which connec'- tion is made with the tank.

Figures 1 to 7, inclusive, and 13 to 15, inclusive, of the accompanying drawings illustrate the preferred construction. The remaining figures illustrate modifications.

Referring to the figures, letAdesignate the bowl of the closet and B the trap forming the outlet thereof, and which is connected to the soil-pipe in the usual manner. The bowl and trap will usually be constructed of iron and enameled interiorly.

C designates the seat, which is counterweighted, so that when not in use it flies up t-o the position shown in Fig. 8.

D designates the flushing-valve, which is a self-seating valve of the class known as a variable chamber-valve.

The bowl A is formed on one side with an exterior chamber orpocket or large hollow lug A', the interior of which communicates with the interior of the bowl and which is preferably cast in one piece therewith. This chamber is preferably cylindrical, or approximately so, and arranged with a Vertical axis, as shown, although this is not essential. The chamber is divided by a horizontal partition or diaphragm E into two compartmen ts-a lowerone F and an upper one F. The chamber is formed with a large hole in its bottom, into which the upper part D of the valve D is thrust and is fastened by screwing upon it a nut. D, which is screwed down tight against the diaphragm E.

The upper part D of the shell of the flushing-valve D is made tubular and projects upwardly from the valve-seat concentrically with the axis of the valve-stem ct, which extends within it. Otherwise the valve D is of the usual construction, having an inlet b, a double-sided seat c, two valves d d on opposite sides of said seat, a cup-leather piston e, to cause the valve to close slowly, a spring f for closingthe valve, and a cup-leather packing g around the valve-stem for preventing leakage. Normally the valve d is pressed against the seat by the spring and shuts off the water,but when the stem is pressed down this valve is unseated and the valve d is brought against the seat, thereby momentarily admitting a dash of Water through the seat into the tube D and thence out through an opening h into the compartment F and thence freely into the bowl. This dash of water constitutes a forewash to wet the bowl. When the stem is released,it is pressed upwardly by the spring f, which slowly reseats the valve d by the slow leakage of water from the upper to the under side of the piston e, as is usual in Valves of this class. During this slow closing the water flows through the Valve and into t-he bowl as before, but constitutes a prolonged flush or afterwash The flushing-water in flowing from theA compartment F into the bowl encounters a fan G, which deflects it laterally and downwardly and causes it to issue in a thin stream against the surface of the bowl instead of spurting into the bowl. This fan may be Variously formed and applied or it may be dispensed with altogether in case the iiushingrim j of the bowl extends low enough and is formed of the proper shape to serve the same purpose.

In the construction shown in Figs. 1 to 7 the fan G and partition E are formed both in one plate, which is of the shape best shown in Fig. 7 in inverted plan and in Fig. 3 in section. The plate is of such size as to fit within the chamber A and rest on a ledge k, Fig. 3, at the bottom of the upper compartment F thereof, and it has a hole 7c formed in it to admit the tubular shell D of the valve through it. When the nut D is screwed down, the plate yis clamped firmly in place against the flange k. The plate is expanded at each side at Z Z, where it enters the bowl, and is thence bent downward to forni the fan G. i

The chamber A is formed with an open top, and is closed or roofed over by means of a iiat plate H,which is formed with a tongue fm on its side nearest the center of the bowl,-

which projects under the top plate n of the bowl A, as shown in Figs. 3 and 4, whereby it is fastened down at this end, and on its opposite end it is formed with a perforated ear, which is fastened to an ear n on the chamber A by a bolt or screw p. This bolt is formed at its upper end with two projecting perforated ears, constituting a fork p', in which is fulcrumed a lever I, counterweighted by aweight l on the outer side of the fulcrum and extending inwardly toward the center of the bowl. This lever rests on top of the valve-stem, and its inner end is encountered by the seat C when the latter is turned down, whereby the lever is pressed down and communicates motion from the seat to the valvestem to operate the valve. This construction of a lever I intermediate of the valve-stein and seat enables the flushing-valve to be arranged at the rear of the bowl on the side at which the seat is hinged and between the two counter-weights W W, Fig. 13, thereof, whereby it is entirely out of the way and not liable to injury.

The upper end of the tubular portion D of the valve-shell opens within the compartment F 0f the chamber A', which compartment has free communication with the bowl above the fan G. In case anyleakage of water should occur past the packing g, this leakage will flow over the top of the tube D and into the compartment F and thence into' the bowl, so that there will be no spurting of water up around the valve-stem and outside of the chamber A nor any overflow or leakage outside of the closet. Similarly in case any leakage occurs through the valve the water ICO IIO

will run into the bowl from the compartment F.

My invention in its preferred construction as thus far described provides a very simple closet, and one which is of cheap construct-ion and not liable to get out of order and which discharges all leakage either through the valve or around the valve-stem into the bowl instead of permitting it to overflow exteriorly.

The modified construction shown in Figs. 8 to 12 diifers from the one alreadydescribed chiefly in that the valve D and chamber A are arranged at the side instead of at the rear of the bowl, and the valve-stem d is operated upon directly by the sea-t insteadof through the medium of an intervening lever. The

.valve is of the same construction already described and the chamber A is cast on the bowl in similar manner, except that the partition or diaphragm separating the lower and upper compartments F and F is cast in one piece with the chamber A instead of being a separate plate. The top plate H is fastened by asingle screw P, as shown in Fig. 9. The outlet from the compartment F to the bowl extends laterally. as shown at q in Fig. 11, and dischargesbehind afan G, which may be cast to the bowl or fastened by a screw or otherwise.

The seat C consists of a circular frame of wood, constituting the seat-plate or ring, fastened to a metal plate L, constituting` the hinge-plate, by screws, as shown. The hingeplate L is formed with pivot pins or pintles a' fr, projecting to opposite sides, and these pintles turn in eyes s s, Fig. S, which are fastened by screws or nuts to the ends of the bracket-arms t t, projecting from the bowl A. There is no novelty in this construction. The seat C is counterweighted by a weight proj ecting rigidly from the hi nge-plate L, as heretofore; but instead of using only a single weight extending to both sides of the middle and casting it integrally with the hinge-plate L, I apply two separate counter-weights WV NV, spaced to some distance apart, so as to leave a clear space between them in the middle and fastenedrigidly and detachably to the hinge-plate L, so that if a counterweighted seat is not desired these weights may be detached without interfering with the pivotal mounting of the seat. To this end the weights lV W are formed each with a tang w, which enters a socket u, formed in one side of the hinge-plate, and into which it is fastened by a screw-bolt Iv, as shown in Figs. 13,14, and 15. Thus a clear space X is left between the weights for the flushing-valve or (in the case of a closet that is flushed from an overhead tank, as usual) for the usual flushing-pipe through which the water passes to the bowl from an overhead tank.

In the modification shown in Fig. 16 both weights W W are cast on a single plate w, which is fastened by screws o o to lugs u u on the hinge-plate L. When the valve is arranged at the side of the bowl, as in Figs. 8 to Prior to my invention the seats of swingseat water-closets have been counterweighted by means either of a rigid weight'castin one piece with the seat-plate, and which, consequently, is not detachable in case itis' desired that the seat shall not be counterweighted, or else by means of a weight suspended freely from a hook or eye on the seat-plate, so thatit hangs freely and may swing or vibrate. This latter construction, while it admits of the removal of the weight, so that the seat shall be no longer counterpoised, is nevertheless objectionable, because of the loose connection of the weight. This feature is particularly disadvantageous for closets designed for prison use, since the weight may be detached by the prisoner and used as a weapon.

My invention provides counter-weights that may be removed, if desired, but which cannot be removed by a prisoner who does not possess the proper tools.

My invention is susceptible of some modification without departing from its essential features. For example, the plate or diaphragm E might be omitted, thereby constituting the chamber A a single undivided chamber. Also, any known and suitable construction of variable chamber o r self-closing valve may be substituted for the particular construction shown. My invention is also applicable in case a flushing-valve is employed of the kind which remains open only so long as it is held open by the pressing down of the seat; but I do not recommend the use of such valves. l'

I claim as my invention the following ydelined novel features and combinations, substantially as hereinbefore set forth, viz:
