. PLUMBING FERRULE Filed 'July 8, 1957 A770/Q/VE Y United States Patent PLUMBING FERRULE Rudolph Kozlowski and John J. Conti, Plainville, Conn. Application July 8, 1957, Serial No. 670,550 2 Claims. (Cl. 4-1) Our invention relates to plumbing fittings, and is directed particularly to an improved adapter ferrule for use in connecting a toilet bowl with the vertical outlet drain stack of a household sewage system.

In modern plumbing systems, wherein rigid outlet pipes are used with toilet bowls, there is the danger that when the house settles, the toilet bowl will be lifted by the outlet pipe and caused to break away from the seal at the floor, thereby causing leakage.

The principal object of our invention is to provide a yieldable connecting pipe structure between a toilet bowl and a rigid sewer stack which incorporates a size-reducing adapter ferrule connected to said bowl by a flexible lead elbow so as to allow settling of the house without lifting the toilet bowl from the floor, and without causing damage to the seal between the toilet bowl and the outlet pipe.

Another object of our invention is to provide an adapter ferrule of the above nature which is formed of a metal, such as brass, in which the outlet side is of reduced diameter and eccentric with respect to the inlet side, and the interior of 'which is smooth and level at the bottom to minimize obstruction to the passage of sewage therethrough.

Another object is to provide an adapter ferrule of the character described which can readily be made of noncorrosive cast metal and which will be inexpensive, longwearing, easy to install, and extremely durable in use.

Other objects, features and advantages of the invention will become apparent from the following description when read with reference to the accompanying drawings wherein:

Fig. 1 is an oblique view of a male ferrule embodying the invention,

Fig. 2 is a vertical view, shown partly in cross-section, of a piping arrangement including the ferrule of Fig. l, for connecting a toilet bowl with a nearby sewage stack,

Fig. 3 is an oblique view of a female form of adapter ferrule also embodying the invention, and

Fig. 4 is a vertical view, partly in cross-section, of a piping arrangement including the ferrule of Fig. 3 for connecting a toilet bowl with a remotely located sewage stack.

Referring now in detail to the drawing, the male adapter ferrule, designated generally by the reference numeral 10, in Figs. 1 and 2, is preferably integrally cast of brass or other suitable noncorrosive metal and is formed with a cylindrical inlet end 11, which may, for example, be of 4% inch internal diameter, and a smaller outlet end 12. which may, for example, be of 3% inch external diameter. The inlet end 11 and the outlet end 12 of the ferrule are eccentrically arranged, and are inter-joined by an intermediate body portion 13 which forms a straight line bottom portion 14 which joins the input and output ends. At all other points the body portion 13 is gradually curved from the input to output ends, as indicated at 15.

The exterior of the inlet end 11 of the ferrule 10 is smoothly finished, as indicated at 16 and the periphery of form of adapter 2,845,631 Patented Aug. 5, 1958 the outlet end 12 thereof is machine finished as indicated at 17. Y t

In :Fig. 2, a toilet bowl 18 is shown connectedwitha nearby sewage stack 19 through the male ferrule 10 as disclosed in Fig. 1. Extending from the toilet bowl 18 through the floor F is a flexible lead elbow 20, which may be of 4% inch diameter to fit within the large outlet 11 of the ferrule 10. The elbow 20 has a vertical upper end which is connected to a floor flange ring of the bowl 18 by the usual wax seal 21. The outer end of the horizontal arm of the flexible lead elbow 20 is fitted within the larger inlet end 11 of the adapter ferrule 10, and is secured thereto by a wiped solder joint 22. The outlet end 12 of the ferrule 10 fits directly into a copper T 23 interposed in the stack 19, which preferably is composed of copper pipe with soldered joints.

Modified form The modification of the invention illustrated in Figs. 3 and 4, differs from that described above in that the female brass ferrule 10a is provided at its small outlet end 12a with a machine finished interior surface 17a for receiving one end of an elongated horizontal three-inch copper pipe 24 connected at the other end with a copper T 23a interposed in a remote vertical sewage stack 19a. As in Fig. 2, a flexible lead elbow 20a leads from the toilet bowl 18a and fits into the inlet end 11a of the adapter ferrule 10a and is secured thereto by means of a wiped joint 22a.

Operation In use, when the floor F sags, the flexible lead elbow 20 will prevent the lifting of the toilet bowl and consequent damage to the seal between the toilet bowl and the outlet pipe which might cause leakage.

Although only two forms in which the invention may be embodied in practice are described in this specification, it is to be understood that these forms are given by way of illustration only, and that the invention is not limited to the particular disclosures, but may be modified and embodied in various other equivalent forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new and for which it is desired to obtain Letters Patent is:

l. A conduit system for joining a toilet bowl to a vertical waste stack, comprising a flexible lead elbow connected at its upper vertical end to the lower outlet of said toilet bowl, a rigid integral ferrule having a horizontal cylindrical inlet portion connected with the horizontal end of said flexible elbow and a horizontal cylindrical outlet portion of smaller diameter than said inlet portion and having its horizontal axis eccentric to the axis of said inlet portion, the interior walls at the bottom sections of said cylindrical inlet and outlet portions lying in a horizontal straight line and being smooth and level to prevent obstruction to the free flow of sewage through the ferrule, and the outlet end of said ferrule being connected to said vertical waste stack.

2. A conduit system for joining a toilet bowl to a vertical waste stack, comprising a flexible lead elbow connected at its upper vertical end to the lower outlet of said toilet bowl, a rigid integral ferrule having a horizontal cylindrical inlet portion connected with the horizontal end of said flexible elbow and a horizontal cylindrical outlet portion of smaller diameter than said inlet portion and having its horizontal axis eccentric to the axis of said inlet portion, the interior walls at the bottom sections of said cylindrical inlet and outlet portions lying in a horizontal straight line and being smooth and level to prevent obstruction to the free flow of sewage through the ferrule,
