This invention relates to improvements in plumbing connections, and particularly to connections leading from toilet bowls.

In supplying various plumbing fixtures to a building it frequently occurs that the finished floor level or the finished side of a wall varies in position from that which was originally contemplated in the plans of the building. When this variation occurs between the actual finished floor level. or the side of a wall, changes are required in the plumbing. This is particularly true in properly positioning a toilet bowl in a building.

An object of this invention is to provide an improved construction for conveying the refuse from a toilet bowl to a soil pipe which permits an adjustment of the toilet bowl so that it may be properly positioned with respect to the finished fioor level or the finished side of a wall, which may vary from that originally planned.

A further object of the invention is to provide an improved construction for what is commonly known in the trade as a cast iron closet bend.

Another object of the invention is to provide an improved construction for connecting a closet bend to the toilet bowl which permits adjustment of the bowl relatively to the bend, and at the same time affords a oint which is rigid and strong and which is gas proof against the escape of sewer gas.

Another object of the invention is to provide a calking ring or what is generally known to the trade as a closet ring which forms the connection between the closet bend and the outlet from the toilet bowl.

lVith the foregoing and other objects in view, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings foran illustrative embodiment of the invention herein.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the floor or the building in its finished condition is indicated 7 at F and in a similar manner a finished wall is indicated W. In order to fully appreciate the advantages of the invention, brief er;-

planation of prior methods of installing toilet bowls in buildings is believed to be required. Heretofore it has been customary to employ a closet bend which is in the form of an elbow and which is connected directly to a soil pipe. One branch of the elbow is caused to extend upwardly throu upper end terminate some distance above what is estimated will be the finished floor level. The upper end 01 this branch is then cut off if it is too high so that its upper end will be approximately even with what is esti mated will be the finished fioor level. A calking ring or closet ring is then caused to be positioned over the upper end of this branch of the closet bend and is fastened thereto by pouring calliing lead the ring 95 and calking it by means ol a calking tool. This ring is positioned upon the outside of the closet bend. The closet bend employed has a diameter which is the same throughout its entire length and which is equal to the @423 the floor and to have its diameter of the outlet from the toilet bowl. Consequently it it should happen that the finished floor level is raised above that originally planned, and this not infrequently occurs, the ring too low for attachment to the toilet bowl causing a considerable amount of expense and labor to make'the corrections in the plumb? It also sometimes happens that the linis ed sr face of t is wall is moved further toward the center of the room than originally contemplated. This may require that the toilet bowl be shifted farther to var-d the cent-er of the room so that its out-let is no longer in alignment with the up-standing branch of the closet bend, causing expense and labor to make the correction.

The improved construction is designed to eliminate these diiiiculties. In the modification shown in Fig. 1 there is a closet bend in the form of an elbow. Such closet bend can be formed of cast iron or any equivalent material, and it is so formed that its upstanding branch 11 is somewhat greater in diameter than the horizontal branch 12 which is adapted to be connected to the soil pipe, not shown. The horizontal branch 12 .has substantially the same diameter as the outlet 13 from the toilet bowl T, the conventional diameter employed for these parts being four inches. It the diameter of the horizontal branch 12 and the outlet 18 is four inches, the tip-standing branch 11 is j'iret'erably made with a diameter of about 6% inches, although it will be understood that the actual dimensions may vary.

The closet bend 10 is first installed in the building and has its rip-standing branch 11 extending upward some distance so that it will project a short distance above what is contemplated as being the finished floor level. The closet bend or elbow 10 is allowed to remain in this condition until the finished floor F is laid and also the finished wall N is constructed. At that time the surplus or projecting portion of the lip-standing branch 11 cut oil so that the top edge of the branch 11 is substantially flush with the floor F. T .is branch may be cut oil in any suitable manner such with a cold chisel.

A calking or closet ring 14 is then positioned within the upper end or" the l. 'anch 11, such rin g having an aperture 15 formed therethrough, and havi g a flange 16 located in a plane below the body of the ring and connected thereto by an annular apron 16 depending from the outer circumference of the ring. This flange. together with the body of the ring, cooperates with the interior surface of the branch 11 to form a groove 1'? within aperture 15. On the under side of the conventional toilet bowl there is a recess 18. This recess is of such size that it will completely cover and receive the upper end of the branch 11 even though it has its diameter increased. llithin this recess there is placed putty, wax, or other material, and the bowl is lowered into place. On the ring 14 on diametrically opposite sides of the aperture 15 there are ears 19 having threaded apertures which receive the lower ends of bolts 20 through the base of the toilet bowlT. The ears 19 are located otherwise than on diameters of the ring 14 and aperture 15 which coincide and they are preterably arranged transversely of the coincident diameters of the ring and aperture. In this manner the toilet bowl is firmly and rigidly fastened to the branch 11 of the closet bend or elbow 10. The calked joint, together with the putty or wax, forms a tight gasproof joint which is equally as strong as the joint heretofore provided in this connection.

From the above described method of installing the connect-ion, it will be appreciated that it is always possible, with the improved construction, to have the upper end of the elbow 1O practically even with the finished floor level so that the bowl will rest evenly on the floor and so that the upper end of the branch 11 is sufliciently close to the outlet 13 to form the desired joint.

The improved joint also provides for adjustment of the bowl relatively to the bend or elbow 10. From an inspection of Figs. 3, 4 and 5, it will be noted that the center of the aperture 15 is otherwise than coincident with the center of the ring 14. If the ring 14 is placed in the position shown in Figs. 1 and 3, the aperture 15 will be so positioned that the bowl T is in its rear-most position with respect to the elbow or bend 10, which cannot be changed after it has been once installed.

If it should so happen that the finished wall surface should vary and be moved toward the center of the room from the position origi nally contemplated, the ring 14 can be reversed from the position shown in Fig. 3 into the position shown in Fig. 4. In such position it will be noted that the center of the aperture 15 is moved on the far side of the center of the branch 11 from the wall IV. Consequently when the outlet 13 is positioned in the aperture, the toilet bowl T will be caused to a."-

sume a position more toward the right from the position shown in Fig. 1, thus accommodating the change in the position of the linished wall surface withoutrequiring achange in the connecting pipe 21 which leads from the supply tank 22.

In this manner a single ring 14 provides "for adjustment of the toilet bowl T, enabling the bowl to be positioned-in either of 'wo positions with respect to the stationary elbow or bend 10. Various sizes of rings can be provided in which the distance between the centers of the aperture 15 and of the ring 14 are varied, such as for example rings may be provided where the distance between the centers is inch, inch, or A of an inch. In this manner by arranging the aperture 15 eccentrically with respect to the peripheral center of the ring 1 a. horizontal adjustment of the toilet bowl T with respect to the bend is pos sible.

It will be appreciated that the improved closet bend or elbow 10 can be constructed in either of several difierent manners,'s0me of which are shown in Figs. 6, 7 and 8. The essential characteristic of all forms of the bend is that the rip-standing branch has a diameter considerably larger than the diameter of the outlet 13 so as to accommodate the ring 14: which is positioned within it, and which has its eccentrically arranged aperture 15.

In the modification shown in Fig. 6 there is an rip-standing section of large pipe 23 forming the rip-standing branch and this section of pipe has its lower end reduced as at 24 and threaded into an elbow 25 connecting it to the pipe 26 which leads to the soil pipe. In this modification there are shown rooves 27 about the upper end of the pipe 93 which facilitate cutting off the upper end of the pipe even with the finished floor level. The same construction can be employed on any modification of the closet bend.

In the modification shown in Fig. 7 there is an rip-standing pipe section 28 of large diameter which has its lower end reduced and 0 formed into a bend, as indicated at 29, adapt ed to be connected to a pipe 30 which leads to the soi pipe.

In 8 there is illustrated a section of pipe having the required large diameter, the pipe being indicated at 31, having a reduced lower end 39. which is adapted to be connect d by means of a call-zed joint to a pipe lea o the soil pipe.

;v of the modifications it is not necessary that i119 horizontal branch 12 of the closet bend be arranged perpendicularly to the plane of the wall IV. It will be understood that this branch may be arranged at any angle with respect to the wall and that the ring ll can be positioned in the upstanding branch ii and have the same advantages as when the branch 12 is perpendicular to the wall IV.

From the above d scribed construction it will be appreciated that a novel toilet connection is provided which has numerous advantages in that an adjustment is provided for the toilet bowl to accommodate changes in the finished floor and wall surfaces of the building. Furthermore the improved connection can be easily and quickly assembled and also inspected.

It also has all of the advantages of joints 7 or connections heretofore provided for the same purpose.

Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.
