3 Claims. 1
The present invention relates to a plumbing apparatus and has for one of its objects the provision of apparatus for facilitating greatly the accurate positioning and holding of an anchoring member or ring in relationship to associated soil pipe.
In connection with the installation of plumbing fixtures such as toilet bowls in new buildings, it is desirable that the fixture holding member be accurately positioned with respect to its associated soil pipe so that the fixture may be anchored without diificulties. The fixture holding member is usually embedded in concrete, but in the process of pouring the concrete or when the concrete is in the process of hardening, the fixture holding member is oftentimes unintentionally moved from its correct position and consequently, difficulties are later encountered when an attempt is made to mount the plumbing fixture on its holding member.
.It is, therefore, an object of the present invention to provide improved apparatus for maintaining a fixture holding member in place while it is being anchored in place. Another object of the .present invention is to provide an improved tool for maintaining a plumbing fixture holder in place while it is being anchored, the tool being characterized by its simplicity and ease of application to existing structures.
The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. This invention itself, both as to .its organization and manner of operation, together with further objects and advantages thereof, may be best understood by reference to the following description'taken in connection with the accompanying drawings-in which:
Figure l 'is a view in elevation and partly in section of an assembly of apparatus incorporating the present invention;
Figure 2 is a perspective view of a tool shown in Figure l embodying the present invention associated with a plumbing fixture holding member;
Figure 3 is a sectional view taken substantially on line 33 of Figure 1.
In accordance with the present invention the plumbing fixture holding member in this particular embodiment of the present invention is accurately maintained in adjusted position with respect to the soil pipe II in the process of anchoring such member It) in concrete I2, the concrete 12 being poured around the member Ill and then allowed to harden.
During the pouringand hardening periods the ring [-0 is firmly held in place on an inverted U- shaped strap [4 having ears l5, l6 integrally formed therewith which in turn have integrally formed therewith respectively downwardly extending cylindrical spacers ll, [8.
Bolt and nut assemblies 22, 23 (which arelater used to fasten the plumbing fixture itself) serve to clamp the flange 2| of the ring shaped member it against the spacers l1, It, the bolt portions of these assemblies 22, '23 respectively passing through the elongated slots I9, '20, the spacers,
18 and apertures in ears 1'5, 16. The por-tion'of mainly, 1) to support strap [4 and ring-shaped member I'll attached thereto; and (2) to provide .a fluid tight conduit and connection with the soil pipe II so that. the soil pipe H andits connections with other soil .pipe (not shown) .may be suitably tested by applying thereto fluid under .pressure which enters through the valve 39 and passes downwardly through the central pipe into the soil pipe.
Resilient annular ring 32 abuts the inner sur- .face of pipe II and maintains a fluid tight connection therebetween, this connection being maintained by maintaining a mechanical pressure between the opposite edges of member 32. This mechanical pressure'is applied by the bearing members 28, 35 which serve as clamping members,'member '28 being slidably mounted on pipe 3| and member 35 beingscrew threaded on pipe 3| such that by turningnut 21 in the proper direction members 28, 35 are drawn together thereby to squeeze the annular resilient ring member 32 into abutment with the innerwall of the soilpipe.
Thus, when the test plug 25 is clamped-into position for testing, the strap l4 issimultaneously clamped into position. Further, the nature of the connection between the test plug and the soil pipe allows adjustment of the position of the supported ring shaped member ID. Usuallyth'e member Ill is positioned so that the underside of the flange 2| is flush with the proposed floor which is subsequently produced by the concrete.
It is noted that the nature of the structure is such that concrete during the pouring operation is precluded from entering the soil pipe.
After the concrete has been poured and hardened the wing nut 21 is loosened thereby to unclamp the strap I4 inwhich case the strap 14 may be removed after taking off the nuts on the assemblies 22, 23. The test plug 25 is completely removed and the ring and bolts extending therefrom are in readiness for the anchoring of the plumbing fixture.
In the process of fastening the plumbing fixture to the ring 10, material such as oakum and a lead ring is disposed within the annular space 40 in accordance with conventional practice.
While the particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of this invention.
1. In an arrangement for accurately assembling a plumbing fixture fastening member in aligned fixed encircling position with respect to a soil pipe, the combination comprising, a device selfsupported solely by its engagement with the interior wall of said soil pipe, said device comprising a threaded open ended pipe extending centrally in said soil pipe, a radially expansible circular gasket encircling said pipe and engaging the interior wall of said soil pipe to secure the device to said interior wall of the soil pipe, a pair of clamping members on opposite sides of said gasket and mounted on said pipe, a nut threaded on said pipe and arranged to move said clamping members towards one another to squeeze saidgasket radially outwardly into engagement with the interior wall of said soil pipe, a-laterally extending strap member having an intermediate slotted portion encircling said pipe, said slotted portion being clamped'between said nut and one I to the said internal wall of the soil pipe, a pair of clamping members engaging opposite circular edges of said annular gasket, one ,of said clamping members being affixed to the lower end of said pipe, the other one of said clamping members being slidably mounted on said pipe, a nut threaded on said threaded pipe adjacent to said other clamping member and arranged to pro- I duce relative movement between said clamping ended elongated slotted portion in the central region, said slotted portion extending generally transversely of the longitudinal axis of said strap member, a pair of ears formed integrally with said strap member and extending longitudinally thereof, each of said ears being apertured, a pair of bolts each having their shanks extending through a corresponding one of said ear apertures, a tubular spacer mounted on each of said bolts between said ears and thecorresponding bolt head, and a fastening nut threaded on each bolt in a position to clamp the corresponding spacer between the corresponding ear and corresponding bolt head, each of said bolts being of such diameter to allow their passage through corresponding open ended slots in said fixture member whereby said fixture member may be clamped between said spacers and said bolt heads.
3. The combination in an arrangement for use in accurately assembling a plumbing fixture fastening member in a fixed aligned position around a soil pipe comprising, a strap member of generally inverted U-shaped form having an open ended alongated slotted portion in its central region, said slotted portion extending generally transversely to the longitudinal axis of said strap member, a pair of cars formed integral with said strap member and extending longitudinally thereof, a device arranged to releasably engage the internal wall of said soil pipe to self-support itself on said soil pipe, means incorporated in said device releasably clamping said central slotted portion, and clamping means for releasably clamping said fixture member to said pair of ears to thereby support said fixture member solely by the engagement of said device with said internal wall, said device comprising: a hollow externally screw threaded pipe, a first clamping member slidably mounted on said pipe, a second clamping member afiixed to said pipe, an annular resilient gasket encircling said pipe and disposed between said first and second clamping members, a nut mounted on said threaded pipe arranged upon tightening to move said slidable clampin member towards said second clamping member to thereby squeeze said annular gasket against the internal wall of said soil pipe to thereby secure the device to the said internal wall of the soil pipe, said slotted portion being of greater width than the diameter of said threaded pipe and being clamped between said nut and said first clamping member.
