Bradley, Santa Ana, Calif. Application November 26, 1946, seia1 No. 712,430

The present invention relates to plumbing .ap-

-paratus and has for one of its objects the prowherein concrete or other flooring materials are applied around the associated soil pipe, it is desirable that the xture holding member may be easily placed in accurate position with respect to its associated soil pipe sothat the fixture may be 'anchored to its holding member without diniculties. 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 often times unintentionally moved from its correct position, and consequently, diiculties 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 assuring accurate position of a xture holding member after concrete or other flooring material is poured around the associated soil pipe.

Another object of the present invention is to provide an improved tool which serves to define a predetermined annular opening around the kend of a soil pipe when concrete or other liooring material is applied around the soil pipe.

A further object of the present invention is to vprovide an arrangement whereby the aforesaid tool is firmly maintained in position during the time that such concrete or flooring material is applied around the soil pipe.

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 1 is a view in elevation and partly in section of an assembly of apparatus incorporating the present invention.

Figure 2 is a sectional view of the soil pipe and associated concrete shown in Figure 1 after the assembly of apparatus shown therein is removed, and further incorporates a correspond- 4 Claims. (Cl. 25-118) 2 1 ing sectional view of a xture holding member which is applied in the annular space between the soil pipe and the concrete.

Figure 3 is a sectional view similar to Figure 2 but with the fixture holding member in place.

Figure4 is a perspective view of a tool shown in Figure 1 embodying the present invention.

In accordance with the present invention, an annular conical shaped space I0 is provided withinwhich the plumbing xture holder II may be placed incorrect aligned position with respect to the end of the soil pipe I2.

The annular space I0 is formed during the time the concrete I3 is poured and allowed to harden around the soil pipe I2, a shield member yI4 being firmly maintained in adjusted position during such pouring and hardening periods. The shield member I4 comprises a hollow truncated conical member I5 having a web member I6 which serves as a fastening means intermediate the ends thereof with the plane of the web memvber I6 perpendicular to the longitudinal axis of the member I5. 'I'he member I6 has a centrally located aperture I1 through which a test plug assembly I8 may pass to hold the composite shield member I4 in adjusted position.

`The test plug assembly I8 serves two purposes; namely, ('1) to support shield member in adjusted position; and (2) to provide a uid tight conduit and connection with the soil pipe I2, so thatV the soil pipe I2 and its connection with other soil pipe (not shown) may be suitably tested by applying thereto uid under pressure which enters'through the valve 20 and passes downwardly through the central pipe 2l into the soil pipe I2.

Resilient annular ring 22 abuts the inner surface of pipe I2 and maintains a fluid tight connection therebetween, this connection being maintained by maintaining mechanical pressure between the opposite edges of member 22. ThisV mechanical pressure is applied by the

bearing members

23 and 24 which serve as clamping members, member 23 being slidably mounted on pipe 2| and member 24 being screw threaded on pipe v2|, such that by turning the fastening wing fastening nut 26 in the proper direction,

members

23, 24 are drawn together thereby to squeeze the annular resilient ring member 22 into abutment with the inner wall of the soil pipe.

In the process of mounting the test plug I8 on the soil pipe I2, the web member I6 is interpositioned between the wing nut 26 and the adjacent end of clamping member 23 so that when the test plug is clamped into position for testing,

r from the `openend of pipe 2 I.

the shield member I4 is simultaneously 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 shield member I4. The inside diameter of the smaller end of the conical member I5 is substantially equal to the outside diameter of the soil pipe I2 so that preferably a close sliding it exists therebetween so 'that during Athe pouring operation "concrete is precluded from entering the soil pipe I 2.

After the concrete has been poured to a level vindicated in Figures 1 and 3k andV then allowed to harden, the wing nut 26 is loosenedthereby to release the pressure on the resilient member 22 to allow withdrawal of the testplug I8 with the shield member I4 assembled thereon.

The conical shape of the assembly I4 is -im-l portant in that it allows easy withdrawal of `Vthe assembly even though the concrete is hardened 'around the outsideof thesliieldli.

It'fis apparentithatthe shield member I4, if desired, may be disassembled from-'the test plug assembly lI8 by unscrewingthe clamping mem- .ber"24"oi of the threaded` pipe 2I in which case 25 the. resilient-men'iber'-'22, clamping member 23 andshield member- I'IlY-inay in'v turn be removed After the annular'spa'ce In listhus. provided,
