WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 268,025, dated November `28, 1882.

` Application ala July 20,1882. (No model.)

To all whom it may concern Be it known that I, FRANCIS WlLLIAM KEL- LY, a citizen of the United States, and a.resident of Minneapolis, in the county of Hennepin and State of Minnesota, have made certain new 'and useful Improvements in I/Vater- Closets, of which the following is a specification.

This invention relates to water-closets 5 andit consists in the construction and arrangement of parts, as hereinafter shown and as specifb cally claimed.

lIn the drawings, Figure l is a transverse section throughthe bowl and tank on the line mw of Fig. 2. Fig. 2 is aplan view of' the bowl and tank with the cover of the tank re-` moved.A Fig. 3 is a section of the tank on the line y y ofthe tank in Fig. 1. Fig. 4 is a side view of the bowl detached. Fig. 5 is a crosssectional view; and Fig. 6 is a plan view, enlarged, of the joint connecting the bowl and its discharge-tube, illustrating the manner ot constructingit. Fig. 7 is an enlarged sectional view of the flushing-valve, and Fig. 8 is the same with the parts disconnected. Fig. 9 is a front view; and Fig. 10 isa sectional view,

enlarged, otl the combined washing and bowl supply valve.

A is the usual earthenware bowl for receiving the deposits, and B' the metal flushingtank, placed alongside the bowl, and the two connected at their contracted lower ends with a large tube, C.

Leading from the tank B', below the tube C, is another Itube, D, either turned oft' to one side and downward at o, beneath the center of the bowl A, or in any other direction that the location of the apparatus may require. At

i the junction of the'tubes C and D avalveseat,

b, is set, upon which a valve rests, as shown. This valve is constructed of a metal disk, c', having a curved lower side and a flat upper side provided with small spurs c2 and rounded Vouter edges, over which disk a rubber cupshaped packing or cushion, e', is adapted to the cushion witll a washer, d2, and nut d3, by which the disk c and cushion e are rmly connected to the stem d. The stem runs up through the cover B2 of the tank B', and also through the seat E, and is provided with the ordinary knob vor Kpullf7 F, whereby the valve may be raised from above in the ordinary nlanner. By this construction of the valve no part of the rubber cushion is left loose to be bent back and forth by the action of the water,

which soon breaks oft' their edges and causes them to leak. In my arrangement the edge of the valve-cushion is turned over and held down upon the disk c by the spurs c2, so that" the rubber is in the same position whether the valve is opened or closed. The rubber will be molded, as shown in Fig. 8, and stretched over the disk when placed in position, so that no springy action will occur to displace it.

Branching from the tank Bis a small flat tube, h', adapted to be connected to a similar tube, h2, branching from the bowl A, wllereby a passage-way is opened between the tank and bowl.

The lower edge of the tube i', leading from the bowl A, is provided with a small collar or rib on the outside, adapted to flt into a small collar, i2, on the tube C, andfheld in place by set-screws t3, as shown in Figs. 4t and 5, the remainder of the space between the tube i and flange i2 being filled with cement ot' any suitablekind to form a gas and water tight joint, the set-screws preventing the strain coming upon` the cement;

B3 is a tube running down the outside of the tank B from its top to the bottom, alld opening intothe tube D below the valve e'. Tile upper part of this tube B3 is larger than the lower part to provide room for a small trap B4, opening at one endinto the tank B and at the other end into the tube B3, thereby forming an overflow for the tank, and by its form serving as a trap to prevent the gas from the tubes passing into the tank, being thus an ordinary water-trap. A small valve, g, will be hinged over the inner end of this trap B4 to be opened only bypressure from within and closed by any back-pressure, to serve as an additional safeguard to prevent the escape of gas from the tubes B3 or D into the tank inevent of the trapfailing to operate.

. G isa valve-casing screwed through the side of the tank Bl from the inside, and connected on the outside with a tube, G2, leading to the hydrant or tank for supplying water to the apparatus.

G3 is another tube, leading from the top of the casing G out through the tank B and into a small projecting tube, G4, on the side of the bowl A. Leading from this tube G4 are two oppositely-branching ports, a a2, opening at angles into the bowl, as shown, so that the stream ot' water from the tubes will be divided and enter the bowl from two directions, as hereinafter shown.

The valve-casing Gl is formed on the inside,

near its forward end, with a smooth conical valve-seat, G5, and hack of the opening into the tube G3 with a double screw-thread adapted to receive a threaded valve-stem, G6, ot' a conical valve, G7, the latter adapted to t upon the conical seat G5. By forming the screwthread in the casing G and on the stem GS double or with two threads, one inside the other, a small movement of the stem around its center will cause the valve to be opened a longer distance than it would be were only one thread used. The stem G5 is continued out beyond the casing G through a stuffing-box, G8, and provided on the outside with a serrated-edged hub, G9, over which a similarlyserrated collar, G10, tits. lInto the side of this collar G10 is secured a rod, H', on the opposite end of which afloat, H2, is attached, the oat adapted to lie upon the water in the tank. By thisv arrangement it will be seen that if the float be raised the' valve will be closed, and if the lloat be lowered the valve will be opened, the double screw-thread on its stem insuring its wide r opening by a comparatively small downward movement of the float. When the valve is thus opened the water from 'the hydrant or supply-tank is thus free to flow into the bowl A through the parts n n2, and thus wash it out, as hereinafter shown.

N is a tube connecting the rear upper parts of the tank and bowl to each other, and pro- I vided at the center with a three-way coupling,

N2, from the bottom of which a tube, N3, branches down to a safeupon or beneath the floor upon which the apparatus rests, and from the side of which coupling another tube, N4, branches and turns upward and outward, and is conveyed to a Ventilating chimney or shaft, the upward turn of the tube being to prevent any water from the bowl or tank from flowing into it. By this means au additional overflow is provided for the tank and bowl through the tubes N and N3 in case of the failure of the trap B4 to operate, while at the same time, by means of the larger tube, N4, a perfect ventilator 'is formed, and by turning the tube N4 upward before it passes to the chimney no water or matter from the bowl or tank can get into it, but will flow off through the tube N3. When the tank and bowl are empty the float H2 will fall and open the valve G7 and allow the water to flow into the bowl through the ports n a2 and iill it up, and also the tank B as far as the line z, until the water has raised the iioat high enough to close the valve G7 again, the valve e having. of course been previously closed.

By adjusting the float H2 higher or lower with relation to the valve G" the water-line z may be raised or lowered at pleasure. This adjustment-of the float is made by means of the serrations on the hub G9 and in the ring Gl", as will be readily seen that by removing the ring Gl0 from the hub G9 and replacing it with another set of the teeth in contact with each other the float may be adjusted to act upon the valve G7 at a higher or lower point ofelevation, and thus raise or lower the waterline z. By making the serrations small the iloat may be adjusted to a very small degree.

When itis desired to discharge the apparatus the valve c is raised, when the water is free to flow out ot' the bowl A through the tubes() and D. The raising ot' the valve e shuts oi" to a very large extent thecommunication between the tank B and tube C, it being raised above the tube C, so that the water from the tank, as soon as the water iu the bowl sinks below the line of. the water in the tank, will begin to run into the bowl through the tube h h2, and the exit from the bowl at i being much larger than the tube h2 la', the bowl will soon be emptied and the water from the tank flow in with some force and wash out the bowl thoroughly. At the same time the oat will fall with the water in the tank,y open the valve G7, and permit the water to flow through the ports n n2. As before stated, these ports, branching in opposite directions, carry the streams of water around the entire inside surface of the upper partof the bowl, and insures its more perfect cleansing. This arrangement is especially beneficial where oval or oblong bowls are used, as one single stream. fails to do the work efficiently. The water will continue to ow through the ports a' a2 until the IOO IIO

valve e is closed and enough water has flowed into the bowl to fill the latter and the tank B high enough to raise the float Hzand close the valve G7. By this construction a much greater force'is given to the4 water that flows from the tank into the bowl than by any other apparatus with which I am acquainted.

In most water-closets heretofore constructed the .water and matter from the bowl passes through the lower part of the tank and comes in contact with the valve, while in this arrangement the water from the tank passes into the bowl after the matter and water have leftit, and acts as a washer7 to the bowl in addition to the washing from the ports n n2. This utilizing of the large body of water from the tank to wash the bowl, and not merely to ow through the lower end of the bowl, as in other devices, is a very important part ot' my invention.

Small wings t may be placed upon the valve G7 or its stem, upon which the water may act to turn the stem and close the valve should the float become broken or detached.

. I do not claim in `this application, broadly, the construction-ot'. the valve, but reserve the right to Vmake the same the subject of a separate application.

5 What I claim as new is- 1. In a water-closet, the combination of deposit-bowl and awater-tank, both adapted to hold water and communicating with each other Y below the water-line of nboth,and a valve which, to when opened, permits the contents of the bowl to be dischargedand` water to pass from the tank through the bowl in quantityT sufficient to flush the bowl, substantially as and for the.,

purpose set forth.

` 15 2. In a water-closet, the combination of a a `flushing-tube, -h h2, r tube C, and a valve, e',

controlling the opening and closing of tube C, 3o `and fitting in the neck of the tank, so as to out o the tank from tube O and cause the water to ow from the tank .into the bowl through the flushing-tube, substantially `asand for the purposes set forth. 3 5

` 4. The combination ofthe bowl A, tank B', connecting-tube N N3, and Ventilating-tube N, substantially as set forth.

5."Ihe combination of bowl A, tank B',

`tubes G2 G3, ports n n2, a valve for controlling 4o Athe How of water from. one ot' said tubes to the other, and a tloat connected to and adapted to be movedto open and close said valve, substantially as set forth.

6. The tube D, having vthe valve-seat b, iu 45 combination with the valve consisting of the disk c', rubber Acushion e', adapted to fold over the edge of said disk, and stein d', substantially as sei: forth.

In testimonywhereof I have hereunto set' 5o my handin the presence of two subscribing witnesses.
