Abstract

ABSTRACT OF THE DISCLOSURE

A pipe fitting comprising a male member and a female element, the element having a wide section of a diameter greater than the diameter of the male member. An integral sleeve is provided on the element substantially parallel to the wide section and spaced inwardly thereof. The sleeve and the wide section together form a groove. The male member slides into the groove to form the joint. In the preferred form of the device, a retainer is provided on the wide section. The retainer is of ring shape and is of greater diameter than the section. Within the retainer is a sealing ring which bears against the outer wall of the male member.

Description

I~ES~RIPTIOM OF T~IE I~JV_TION
The present invention is directed to an improved joint for pipe, more specifically for pipe made of plastic.
In the past, it has been known to join two pieces of pipe toyether b~ various means. For example, the male half is sometimes formed with a taper at the end which fits into the Eemale member. Such joints are operative, but lack flexibility and ti~htness. Modifications of such joints include those in which a flange is provided on the outer member which contains a sealing ring. l'he ring bears against the inner member and sub-stantially prevents leakage. Even such joints, however, have no axial flexibility. The inner portion must be forced into the outer one as far as it will go in order to obtain a tight seal and a Eirm joint.
In prior art devices of this general character, there is usually a gap between the end of the male member and the shoulder of the female member. This gap provides a hollow which encourages the deposit of any solids entrained in the fluid flowing ~ -in the pipe. As a result, such joints are subject to being clogged and the flow therethrough restricted.
It is, therefore, among the objects of this invention to provide a pipe joint which has substantially smooth inter~or walls and which will minimize deposition and build-up of any entrained solids.
It is also among the objects of the present invention ; to provide a pipe joint which not only seals well, but permits axial adjustment.
To this end, in one of its aspect, the invention pro-vides a pipe fitting comprising a male member and a female element in which the female element has a wide section of diameter "~ .

1 greater than the diameter of the male member and an inteyral sleeve or flange substantially parallel to the wide sectiGn ana spaced inwardly thereof thereby forming a groove therebet~7een into which the male member is inserted.
In another of its aspects the invention further provides a pipe fitting comprising a male member and a female element in which the female elemen-t has a wide section of diameter yreater than the diameter of the male member and an integral sleeve or ~lange substantia]ly p~rallel to the wide section and spaced inwardly thereof thereby forming a groove therebetween into which the male member is inserted, and, in which pipe fitting a retainer is provided on the wide section of the female element and a sealing ring in the retainer whereb~ the sealing riny bears against the outside of the male member to effect a seal.
In carrying out the present invention, a male member and a female element are provided. The element carries a section on its end which is wider than the mean diameter of the element and, of course, also wider than the outer diameter of the male member. The element also carries an integral sleeve-like extension or flange substantiall~ parallel to and spaced inwardly from the wide section. Preferably, the base of the flange is at substantially the same point as the base of the wide section.
The flange and wide section between them form a groove into which the male member fits.
~ retainer, consisting of a portion of the section of greater diameter than the remainder thereof, is provided on the wide section. Within the retainer, a sealing ring is positioned so that, when the male member is in the groove, the inner sur-face of the ring bears against the outer wall of the member.In this manner, the seal is e~fected.

Further objects and advantages of the invention will appear from the following description taken together with the ~3t 1 accompanying drawings consti-tu-ting a par-t hereof, in which like reference characters indicate like parts, and in which Fig. 1 i5 a perspective view of the joint of the presen-t invention;
Fig. 2 is a section along line 2-2 of Fig. l;
Fig. 3 is an enlarged fragmentary sectional view of one embocliment of the present invention; and Fig. 4 is a view similar to that of Fig. 3 of another modification of the present invention.
~eferring more specifically to Fig. 2 of the drawings, pipe joint 1 is composed of male member 2 and female element 3.
Element 3 is provided with wide section 4 and flange 7 which together form groove 8.
As may be seen from the Fig. 2, the flange 7 preferably comprises a sleeve integral to the female element 3, which integral sleeve extends axially in the same direction as the wide .
section 4 and is radially spaced inwardly of the wide section 4.
In addition, section 4 contains retainer 5 which holds sealing ring 6 in place~ Sealing ring 6 bears against outer wall 10 of member 2 in order to form the desired seal.
In one form of the invention, flange 7 is provided with taper 9. This facilitates the entry of member 2 into groove 8.
In the form of the invention shown in Fig. 4, flange 7 is straight and parallel to section 4. Member 10 fits into yroove 8 in the usual manner. It is preferred to provide an inward facing bevel 11 at the free end of flange 7. Thus, when the joint is complete, the flow of fluid is as smooth as possible.
As a result, the tendency of entrained solids to deposit and build up at this point is minimized~
It is also a feature of the present invention that it is unnecessary for the end of memb0r 2 to actually contact the ~ k, ,j;".

1 ~otbom of groove 8. Since the seal is effected by ring 6 in retainer 5, a substantial amount of axial adjustment i5 permitted without any loss of fluid tightness.
While only a limited number of specific embodiments of this invention have been expressly described, it is nonetheless, to be broadly construed and not to be limited except by the charac-ter of the claims appended hereto.

Claims (4)

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. A pipe joint comprising:
a male member having a substantially constant cross-sectional diameter at least at an end thereof;
a female element having a peripheral wall encirclingly defining a cross-sectional diameter thereof substantially the same as that of said male member, and said wall including an end portion unitarily and continuously extending therefrom and having a cross-sectional diameter greater than the diameter of said male member end for receiving the male member end within the widened end portion of the female element wall to form a joint therebetween;
an integral sleeve on said female element spaced peripherally within and axially extending substantially parallel to the widened end portion thereof, said widened end portion extending axially at least as far as said sleeve, and said sleeve and widened end portion defining therebetween an interior groove for accomodating said end of the male member to form the joint;
a retainer on said widened end portion of the female element wall;
a sealing member carried in said retainer so as to bear against the male member end received within said female element for effecting a substantially fluid tight seal there-between and for enabling relative axial movement between the male member and the female element while maintaining said substantially fluid-tight seal; and means on said sleeve for facilitating entry of said male member end into said groove.
2. A pipe fitting according to claim 1, said means comprising a radially inwardly-directed taper at the end of said sleeve.
3. A pipe joint according to claim 1, said sleeve including a beveled end on its radially inwardly-directed surface for facilitating a smooth and unencumbered flow of fluid passing between the joint formed of said male member and female element.
4. A pipe joint according to claim 1, said widened end portion extending axially beyond said flange.
