3 Claims.

This invention relates to an elbow fitting for wallsupported water closets. These closets are usually supported on a wall by means of bolts that passthrough the wall, and secure the closet to an elbow fitting on the rear side of the wall. This elbow connects with the sewage waste pipe. The opening through the wall is usually made of considerably larger diameter than the pipe connection, or thimble, that passes through the wall from the delivery orifice of the closet, and it is the usual practice to provide the elbow fitting with a plate that extends down from the upper portion of the elbow, and this plate constitutes a face plate to which the bolts for sup porting the closet bowl are fastened, the bolts extending from the face plate through the wall. These bolts, which secure the closet bowl to the wall usually include a single lower bolt, which is located in substantially the same vertical plane as the axis of the down leg of the elbow fitting. A portion of the face plate that extends down to the floor of such fittings is usually not of great width, and in shipping these fittings there is' some danger that this portion of the face plate will become roken; The .general object of this invention is to provide fittings of this type with features of construction, which will operate to provid-eian effective brace for the lower portion of the face plate.

When a lower bolt, such as referred to above, is employed located in line withthe down leg of the elbow, it is not possible to insert this bolt from the back of the plate, and hence it has been usually necessary to introduce such a bolt 1 from the forward side of the plate and apply the nut in the narrow space between the down leg of the elbow and the downward extension or supporting leg of the face plate. By reason of the-very narrow space in which the nut is located, it is relatively inaccessible and difficult to tighten up. One of the objects of the present invention is to provide a construction which will facilitate the application of the bolt with the bolt head located between the face plate and the down leg of the elbow, and to construct the bracing means between the elbow and the face plate in such a way that it will operate effectively as a brace, and at the same time prevent rotation of the bolt head when the nut on the forward side of the plate is being tightened up.

Further objects of the invention will appear hereinafter.

The invention consists in the novel parts and combination of parts to be described hereinafter,

all of which contribute to produce an efficient fitting for wall supported water closets.

A preferred embodiment of the invention is described in the following specification, while the broad scope of the invention is pointed out in the appended claims.

In the drawing:

Fig. 1 is avertical section through the supporting plate for the closet, and showing the closet in side elevation, and also the elbow fitl ting embodying my invention. This view also indicates the floor level, and indicates in dotted lines the neck that connects to the sewerage Waste'pipe.

Figure 2 is a vertical section through the supl5 porting plate and through the elbow fitting, in a plane passing through the longitudinal axis of the down leg of the fitting, and this View shows the rear portion of the closet broken away so as to illustrate the connection to the delivery orifice of the closet. This view is upon an enlarged scale, and shows the forward portion of the closet broken away. It also shows a portion of the waste pipe connection in cross section and broken away.

Figure 3 is an elevation of the elbow fitting on the side of the face plate.

Figure 4 is a horizontal section taken about on the line 4-4 of Fig. 2, and further illustrating details of the construction of the fitting.

Referring more particularly to the parts, I represents a closet of any common construction, which is supported-on a supporting wall 2. This is usually accomplished by providing a flange 3 at the rearof the closet, which is secured to the wall by bolts, as will be described more particularly hereinafter. In-the present instance, the delivery orifice 4'. of the bowl is clamped up against a neck or thimble 5, which extends through an opening 6 in'the wall from its rear 40 side, and this neck is either integral with or screwed into an elbow fitting 1. This elbow fitting has a down leg 8, which extends down, in a substantially vertical position, and the lower end at the floor line 9 connects to a waste pipe or neck I ll extending up from the same. In the present instance, the closet is secured by three bolts, including two bolts such as the bolt I! (see Fig. 1) and a lower bolt l2. The two bolts II are located on each side of the closet, and the lower bolt I2 is vertically in line with the central axis of the bowl and the central axis of the down leg 8 of the elbow 1. The elbow I also includes a face plate l3. The lower portion of the face plate I3 is preferably of reduced width (see Fig. 3) and extends down to the floor so that its lower end rests on the floor, and to support the weight of the elbow fitting l and its extension or thimble 5..

The space between the down leg 8 and the face plate I3 is quite narrow, as indicated in Fig. 2, and the head of the lower bolt at this point is relatively inaccessible to a workman with a wrench. In some cases, the supporting plate is not tiled on the outer side, but in some constructions the head of the bolt at the back of the plate is plastered in and made completely inaccessible by other workmen before the plumber commences to install the closet, which must be done after the tile setters have set the tiles on the face of the wall. The inaccessibility or the bolt head at the back of the plate is probably the reason for the adoption of the custom of not using a bolt with a head but using instead a double-threaded stud bolt, which has been mounted by means of a threaded connection in the face plate with a clamping nut on the inner end toreceive a clamping nut that seats against the inner face of the plate. In some constructions, the back of the plate is completely inaccessible. It is advantageous to provide a siot for the lower bolt, enabling this bolt to be set at the proper height to enable it to align perfectly with the bolt hole in the flange of the closet.

In accordance with my invention, I provide the lower portion of the face plate l3 with a bolt slot IS, the upper end of which is enlarged to form an opening 31, through which the head l5 of the bolt may be passed. In assembling the parts, the head E5 of the bolt l2 would be inserted through the enlarged opening I! and the bolt would then be dropped down in the slot to a point opposite the corresponding hole in the flange of the closet. In order to prevent the bolt head l5 from rotating, and at the same time to form the necessary brace for integrally connecting the down leg 8 and the lower portion of the face plate, I provide two integral webs I!) that connect these parts, and these webs are located near enough together so that they will lie near the fiat sides 20 of the bolt head I5 (see Fig. 4). In this way, these integral webs will operate to prevent breakages of the fittings in shipping them, and will also facilitate the attachment of the fitting to the closet. The upper bolts H, in accordance with the usual practice, may be constructed as stud bolts passing through the face plate I3 with a jam nut ll clamped up against the back of the face plate.

The wall 22 of .the closet around the delivery orifice 4 is preferably provided with the usual annular groove 23 that registers with a similar annular groove 24 at the adjacent end of the neck or thimble 5. These half round grooves 23 and 24 form an annular socket to receive a gasket 25. If this gasket 25 is made of metal, it will also assist in supporting the closet. The elbow fitting I may be provided with the usual air vent pipe 26.
