To all whom it may concern:

Be it known that I, William Scott, a citizen of the United States of America, and a resident of the town of Medford, in the county 5 of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Siphon Water-Closets, of which the following is a full, clear, and exact description.

This invention in siphon water-closets, in io substance, consists, first, of an earthenware b<5wl having its pedestal chambered and otherwise adapted to receive and practically to cover and inclose a metal pipe and to allow of its proper connection to the bowl at its 15 discharge-opening and to the waste-pipe; second, of means to connect a metal pipe to an earthenware bowl at the discharge-opening of the latter; third, of an improved lever by which to open the tank-valve to discharge the 20 water of the tank, and, fourth, of an improvement in the short leg of the siphon-pipe of the tank, all substantially as hereinafter described.

In the drawings forming part of this specifi25 cation,Figure 1 is a side elevation of the siphon water-closet. Fig. 2 is a central vertical section from front to rear of the closet, Fig. 1. Fig. 3 is a horizontal section, line 3 3, Fig. 2. Fig. 4 is a perspective view, enlarged, of the 30 packing-ring. Fig. 5 is a perspective view, enlarged, of the split ring. Fig. 6 is a central vertical section, enlarged, of the split and packing rings placed together. Fig. 7 is a plan view of the tank, its siphon-pipe, valve 35 to said pipe, and lever to open said valve. Fig. 8 is a longitudinal vertical section of the tank and in part a side view of the siphonpipe and a vertical section of the lower and open end of short leg of said pipe. Fig. 9 is 40 a side view of the operating-lever for valve of tank.

In the drawings, A represents the upper or bowl portion, and A³ is the lower or pedestal portion, of an earthenware or other such like 45 bowl. The bowl A is formed, as usual, to have water entered into it from a supply-pipe B, that leads from a water-tank C, and also to have water discharged from it passingthrough a water-passage A³ in continuation 50 and making part of the water-trap of the bowl and out at an opening A⁵, all substantially as well known.

As this invention is particularly shown, the discharge-opening A⁵ of bowl is connected to one end of a water-trap E³, which makes part 55 of a cast-iron or other suitable pipe E, and has its opposite end continued upwardly and rounded at E⁸ and thence downwardly at E⁴, of suitable length to lead through and to project below the floor F of the room on which the 60 bowl is placed, and below the floor to be entered into the under side of a shouldered hub of a waste-pipe and therein packed tightly in any suitable and well-known manner.

The metal pipe E, as shown, extends from 65 rear to front of and underneath the bowl A, and it lies within a chamber A⁶ of the pedestal A³. This pedestal-chamber A⁸, as shown, has side walls A⁷ A⁸ and a front wall A⁹, and these walls are continuous and together make 70 the pedestal,and said metal pipe E on its upper and opposite vertical side and front portions is inclosed in said chamber, and the pipe preferably has a base E³ for its better rest on the floor F. At the rear portion of the bowl is a 75 horizontal projecting flange A¹⁰ at and about the discharge-opening A⁵ of the bowl. The rear end of the metal pipe E is presented toward the under side or face of the bowl-flange A¹⁰, and it is connected to and fastened 80 against said face of said flange, and their joint is packed all by means-consisting, in substance, first, of a metal or such like rigid flat ring H, having a downward-projecting flange H³ around its inner edge and split dia- 85 metrically and vertically into sections, joined transversely by headed screw-bolts H⁸, passing loosely through one and screwing into the other of adjacent vertical earpieces H⁴of the ring; second, of an india-rubber or 90 other such like compressible gasket or ring J of a shape corresponding to said metal ring, but preferably not split, and adapted by its flange to fit within the flange and lie upon the outer face 0 fthe metal ring, and, third, 95 of headed screw-bolts it, entered through suitable holes located at intervals of said metal ring and of said compressible gasket and bowl-flange and having screw-nuts K³screwed upon them. 100

In applying the described means of connection for a metal pipe E and a bowl A the ring H (its sections being loosely held together by the screw-bolts H³) and the gasket

572,575

J, placed in the ring, as described, are together placed around the outside of the pipe E at or near its end which is open and toward the bowl discharge-opening A⁵ and then 5 lifted to make close seat of gasket against seating-face therefor of bowl-flange, on which the ring by turning up the screw-bolts H³ of its sections is closed about the gasket, closing it in turn tightly about and on the pipe, io and then by turning up the screw-nuts K²of the screw-bolts K, located in the bowl-flange, the ring and gasket are made fast to the bowl-flange, tightlj’ closing the gasket thereagainst and as a whole securing a tight and 15 close connection of bowl and pipe. In attaching bowl and pipe E, as stated plainly, care is to be taken that a tight and close joint is made of gasket, both with pipe and bowl-flange.

The connection of bowl and metal pipe described is advantageous in that the ring and its gasket can be adjusted lengthwise on the pipe to accommodate them to varying relative heights of the bowl-flange and the open 25 end of metal pipe, all so liable to occur because of variations in the height and in the form of the jointing-face of the bowl-flange, the results of molding the bowl, and otherwise, all as well known. Again, a chamber30 ing of the pedestal and a seat-facing of an earthenware bowl, all substantially as described, secures not only a practical inclosure of a metal pipe E, but also permits connection of bowl and said pipe to be readily made 35 and without either disfigurement of the bowl or of its pedestal, or of exposure to any appreciable degree of the pipe.

The bowl described, in combination with a metal pipe E, having a water-trap E², as par40 ticularly explained, secures a double trapping of the discharge-passage of the bowl and a column of air between said two traps, but this of itself is not new.

So far as has been in detail explained it is 45 obvious that the water-trap of the pipe E may be dispensed with; again, that the direction of the run of the pipe E as to the bowl-pedestal and the chambering of the pedestal may be changed to accommodate varying positions 50 of the discharge-opening of the bowl and of the waste-pipe to be connected by the pipe E; again, that the seating and jointing face of the bowl for connection with the pipe E may be varied in position to suit a different posi55 tion from that shown of the open end of the pipe E, and, again, that other means of connection of the pipe E and bowl may be used, and all without departing, in substance, from the features of this invention, to which such 60 obvious modifications may and do pertain.

L is an ordinary hinged valve located in the tank and arranged, as usual, to be opened for passage through the pipe B of water from the tank to the bowl.

M is an upward extension of the pipe B from valve L, and this extension at its upper end

M² is rounded over and thence has a downward extension M³, ending near the floor C²of the tank, and all so that the whole makes a siphon-pipe for a discharge by its siphon 70 action of the contents of the tank, first having set the water in motion through pipe B by an opening and then closing of valve L of said pipe. The downward extension M³ is the short leg, and the remainder Μ² M and its 75 continuation B is the long leg, of the siphonpipe, and heretofore as siphon-pipes in siphon water-closets have been arranged and constructed their siphonic action is and can only be broken either partially or wholly by the 80 entrance of air at the open end of the short leg of the siphon-pipe, thus causing oftentimes (and, in fact, most generally) such a flow of water through the bowl that at the end of the water-flow no substantial amount of 85 water can or will be left standing in the trap of the bowl.

This invention aims to and practice and experience have shown that· it avoids the objection stated, and to that end and in this re- 90 lation the devices of the invention consist of a series of perforations a a a, shown as three in number, but which may be more or less than three, three, however, being found practical. These perforations are located each in 95 a different horizontal plane of one side of the short leg of the siphon-pipe. Each perforation is small and the whole series taken together are of a considerably less superficial area than the open end of said short leg. 100 The perforations separately and together admit air to the siphon-pipe when the water of the tank has been drawn off from the tank to and below their level, and thereby is secured a gradual reduction or. breaking, or, as it 105 were, a tempering of the force of the siphonic discharge before it is fully arrested, and all so that not only is the desired discharge in quantity of water from the tank secured, but also standing water in the bowl to the height no desired, the latter result being made most sure and reliable.

N is a lever which is arranged vertically edgewise and is hung intermediately of its length on a horizontal fulcrum-pin N² of one 115 of the side Avails of the tank C. One portion of this lever lies within and along the inner face of said side wall of the tank and the other portion projects over one end of the tank, and there a chain or such like (not shown) is to 120 be attached for operating it.

N³ is an arm that at one end is fastened by a set-screw N⁴ rigidly to the portion of the lever which lies within the tank and at its other end is over the tank-valve, to which it 125 is connected by chain or such like. (Not shown.) This arm N³, near its point of attachment to lever N, has two radial earpieces N⁵ N^s, each in position to serve, according as the lever is fulerumed at one or the other end 130 of the tank, as a rest and stop, by contact with the upper edge of the tank, to the down

572,575 ward movement of the portion of the lever to which the tank-valve is to be attached, as stated.
