To @ZZ wiz/0m, it mayy concerta- Be it Known that l, JOHN H. STEVENS, Jr.,

of Cambridge, in the'countyof Middlesex and State of Massachusetts, have inventd certain new and useful Improvements in Seat Attachments foi\vater-Closets, of which the following, taken in connection with the accompanyingr drawings, is a specification.

My invention relates to seat attachments for water-closets; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the accompanying drawings and to the,

my invention is clearly pointed out.

Figure l of the drawings'is a sectional elevationv of a water-closet, illustrating my invention, the sectional portion being cut through the center of the bowl and the flushing pipe, Spud, or passage. Fig. 2 is a partial plan of saine. Fig. 3 is a partial horizontal section on line .r a: on Fig. l, looking up.

Fig. 4 is a partial vertical section on line y y' on Fig. 3. Fig. 5 is a sectional plan of the seat and cover hanging devices, the cuttingplane being on line a z on Fig. 6; and Fig. 6 is a sectional elevation of the saine, the. cutting-plane being on line fu n on Fig. 5.

Water-closets have been made in whichthe seat and cover hinges have been secured directly to the porcelain closet, and it is a very desirable thing to do; but as heretoforek constructed the porcelain is liable to be subjected Yto so great a strain as to break the porcelain,-

owing to an obstruction accidentally being placed'between the seat and bowl, near the rear side thereof, so thatvwhen a person sits down upon the seat said seat acts as a lever and the obstruction as a fulcrum to lift the hinge connection to the bowl. n,

The object of my present invention is to obviate this objection; and to this end I construct the closet and its seat and cover attachments as illustrated in the accompanying drawings, in which A is the closet proper, made of porcelain or earthenware, and may be made of any of the well-known forms, as hopper, Siphon, or front'or rear Wash-out, and may he provided with any suitable arrangement for flushing the bowl and for ventilating the same.

projection A is formed the passage l), to the outer end of which may be coupled in any well-known manner the'Water-supply pipe (not shown) for flushing the bowl, the inner endof said passage b' being connected with the annular passage c, as shown. The rectan gular projection A also has formed therein a ventilating-chamber c on each side of the flushing-passage 1),'which chambers communicate at their inner ends-with the interior ot" the bowl and are each provided with an opening therento, in either one of which the ordinary Ventilating-pipe may be inserted,wh ile the other may be capped, the particular location of the Ventilating-pipe being determined by the circumstance ol' each individualcase. These openings to receive the Ventilating-pipe may be in the rear walls of said chambers, as

shown, or they may be in the top o r side walls of said chambers, or there maybe but a single Ventilating-chamber, wit-hout in any way i aiecting the principles of my invention.

Two bracketsl or stands d d are secured to the rear upper surface of the projecting portions A' of the closet by means f the bolts e and nuts e', said bolts passing through the upper plate of said projection with their lower ends within the ventilating-chambers c and each provided witha rubber washer f and a metal Washer g Ibetween the nuty e and the upper plate of said Ventilating-chamber.

To each of the stands d d is pivoted one end of a link h, the opposite end of which has pivoted thereto by a common fulcrum-pin 'i the two rods j and k, eachhaving formed upon its movable end a screw-thread suitable to screw into the seat S andl cover C, respectively, the holes in said seat and cover being counterbored to receive a portion of the length of the larger cylindrical portion of each of said rods, as shown in Figs. 2 and 4;

The links h h are each provided on the under sides of their inner ends with a downwardly-projecting annular lip or chambercd IOO hub Z, to.the exterior of which is screwed the coupling m, in a bearing in the bottom of which is fitted the hub n, having formed thereon the annular collar 'n' to limit the downward movement of said hub and having a spring 0 interposed between said collar and the upper surface of the chamber in the under side of the link h, as shown in Fig. 6.

'lhe seatS and cover U are each provided with rubber buttons or cushions r set in their under sides to rest respectively. upon the closet and the seat.

The ends of the hubs 'n n rest upon the upper surface of the rearward projection A', and when a person sits upon the seat S said hubs and the rubber cushions fr yield, so that the seat is depressed bodily, and when the weight is removed the seat rises bodily to the extent of the expansive force of the cushions r and the springs o,thelinks h moving slghtlyabout their pivotal connections to the stands d d. If, however, an obstruction should be placed between the seat and the bowl at a point between thepivotal connections of said seat to the links h and the center of the seat and a person sits upon the seat the front of the seat will be depressed and the rear would be raised, which may be done without danger of injury to the crockery because of the fact that the forward ends of the links 7L are free to be moved upward about their pivotal connection to the stands d d.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination ofA an earthenware water-closet; a fixed hinge-section secured directly to said closet; a seat mounted upon said closet; a hinge-section secured firmly to said seat; a hinge-section pivoted at one end to the hinge-section secured to the closet and at its other end to the hinge-section secured to the seat; and a yielding hub or cushion interposed between said hinge-sections andthe closet to normally hold the rear of said seat in a raised position.

2. The combination of an earthenware water-closet provided with a chambered projection; a seat mounted upon said closet; hingesections secured to said seat; hinge-sections mounted 'upon said closet; fastening devices within the chamber of said projection for securing said hinge-sections to said closet; and hinge-sections pivoted at one end to the hingesections secured to the closet and at their othtsr ends to the hinge-sections secured to the sea v3. An earthenware water-closet having a chambered projection, a flushing-passage and a Ventilating-chamber formed within said projection, and means for connecting the flushing and Ventilating pip'es thereto; in combination with fixed hinge-sections mounted upon said projection; bolts passing through said hingersections and the walls of said projection; into the chamber thereof; nuts fitted to said bolts wit-hin said chamber; a seat mounted upon said closet; hinge-sections firmly secured to said seat; and links connecting the hingesections secured to the closet with the hingesections secured to the seat.

4. The combination of an earthenware water-closet having a rectangular, chambered rearward projection; fixed hinge-sections secured to said closet; a seat mounted upon said closet and provided with hinge-sections firmly secured thereto; hinge-sections pivoted at one end to the sections secured to the closet-and at their other ends to the sections secured to the seat and provided at their front ends with downwardly-projecting and yielding hubs to bear upon the closet.

5. The combination of anearthenware water-closet provided with a chambered projection; a seat mounted on said closet; a cover mounted on said seat; a hin ge-section secured to said seat ;4 a hinge-section secured to said cover; a hin ge-section supported upon said chambered projection; a fastening bolt or screw for fastening said hinge-section to said chambered projection, and extending into the interior of said chamber; a nut within said chamber for clamping said bolt in position; and a link or hinge-section pivoted at one end to the hinge-section on said chambered projection, and connected at its other end, by a common fulcrum-pin, or pivot, to the hingesections ou the seat and cover.

G. As a means of securing the seat and cover to an earthenware Water-closet the combination of fixed hin ge-sections secu red to said closet; a seat provided with hinge-sections firmly secured thereto; a cover provided with hinge-sections firmly secured thereto; and links or hinge-sections pivoted at one end to the hinge-section secured to the closet, and at their other ends connected by a common fulcrum-pin or pivot to the hinge-sections secured to the seat and to the hinge-sections secured to the cover.

7. In combination with an'earthenware water-closet, a seat mounted upon said closet;

and a hinge connecting said seat to said closet, and made in three parts, one of which is bolted directly toa rearward projection of said earthenware closet, anotherpart is firmly secured to the seat and the third part is pivoted at one end to the section secured to seat, and at its other end to the hinge-section secured to the closet, said pivotal centers being in the same horizontal or nearly horizontal plane, and so constructed that the rear of the seat may be lifted from the closet while thefront of the seat rests upon the closet, without danger of breaking any of the parts.`

In testimony whereof I have signed my name to this specification, in the presence ot' two subscribing witnesses, on this 10th day ot' December, A. D. 1894.
