WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 430,855, dated June 24-, 1890.

Application filed August 5 1889.

To all whom it may concern.-

Be it known that I, GEORGE B. HOWELL, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in \Vater-Closets, of which the following is a specification.

My invention consists of an improvement in the water-closet shown and described in the patent of Thomas Kennedy, No. 376,002, dated January 3, 1888, the object of my invention being to supply both the bowl and siphon-jet of such a water-closet by means oi one pipe, and to dispense with the necessity for trapping this pipe in the service box or reservoir of the closet. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a side view of suflicient of a water-closet to illustrate my invention. Fig. 2 is an end view of the same, looking in the direction of the arrow, Fig. 1; and Fig. 3 is a sectional view of part of the closet.

The water-closet described in the beforementioned patent of Kennedy consisted of a bowl having a siphoned discharge-pipe, in which the siphon action was set up by the operation of a jet of water entering the upper end of the long leg of the siphon and producing a partial vacuum therein, so as to cause the flow of water from the short leg of the siphon into the long leg. The patented device, however, was provided with two pipes leading to the service-boX, one of these pipes supplying the water for flushing the bowl of the closet and the other supplying the jet, and as in said closet there was no trap between the soil-pipe and the long leg of the siphon it became necessary to trap the jetpipe in the service box or reservoir, in order to prevent the escape of sewer-gas into the room or apartment containing the closet.

In carrying out my invention I use a single supply-pipe a, which communicates with one end of a loop b, the opposite end of which forms the jet-pipe d for the long leg of the. siphon, the loop and jet-pipe being preferably formed of the same material as the bowl and siphon-pipe of the closet, and

Serial No. 319,713. (No model.)

the loop lying closely to the opposite sides of the siphon-pipe and passing from one side of the same to the other beneath the neck formed where the short leg B of the siphon joins the long leg D of the same. From the upper or inlet portion of the loop I) a branch f extends to the bowl A, this branch communicating with the space behind the flushing-rim g of the bowl, and also, by preference, communicating directly with the bowl through a drip-passage 2'. \Vhen water is first permitted to flow through the pipe a, therefore, a portion of it passes through the loop I) and supplies the jet-pipe cl, and another portion passes through the branch f into the flushing-rim of the bowl, so that the latter is flushed simultaneously with the starting of the siphon by the jet. During the latter part of the fiow the volume of water is not more than enough to fill the branch f, so that it seeks the readiest means of escape by passing through said branch into the bowl, the action of the jet ceasing, so as to permit the latter part of the flow to fill the trap at the bottom of the bowl. When the flow ceases, the loop I) is filled with water up to the level of the bottom of the branch f, so that it forms an effective trap or seal for preventing gas from the soilpipe from gaining access to and passing into the room or apartment through the supplypipe to or rim g of the bowl.

Having thus described my invention, I

claim and desire to secure by Letters Patent 1. The combination of the bowl and its siphon discharge-pipe with a single watersupply pipe leading from the reservoir and terminating in a trapped loop discharging into the upper end of the long leg of the siphon, said loop having a branch located below the upper bend of the trap and extending to the flushing-ring of the bowl, substantially as specified.

2. The combination of the bowl and its siphon discharge-pipe with a single watersupply pipe leading from the reservoir and terminating in a trapped loop fitting snugly to the siphon discharge-pipe on each side and crossing beneath the neck of said pipe, name to this specification in the presence of said trapped 100p discharging into the top two subscribing witnesses. of the 1on leg of the si )hon and havin below the 11 per bend a braneh extendin g to HOWVELL' the flushing-ring of the bowl, substantially Witnesses: as specified. WILLIAM D. OONNER,

In testimony whereof I have signed my HARRY SMITH.
