Abstract
Abstract A form in which concrete, or an equivalent moldable material, is poured to provide a finished product. A panel or wall portion of the form or mold is equipped with means for distributively positioning and embedding hollow sleeve-like anchors or fittings. Each means or device embodies a plastic or an equivalent insert or dowel over which the anchor or fitting is sleeved and temporarily held in a manner that it can be embedded at the desired locale in the finished product. After the poured material hardens, adapter means-which constitutes a lower disposable component part of the dowel-is broken off at a frangible or preweakened point. The finished product with the dowel-sealedanchors is freed for shipment. The adapter stays put in the form until it is subsequently dislodged and discarded.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
For use in conjunction with an open-ended screw-threaded prescribed hole in a predetermined wall of a concrete mold: a positioning, setting and retaining device for a hollow internally screw-threaded fitting of a predetermined type designed and adapted to be embedded in a manner to serve as a bolt-holding anchor, said device comprising, a one piece plastic unit embodying an elongated externally screw-threaded rigid dowel closed at one end and having an outstanding integral wall abutting flange at its other end, said dowel being provided with an elongated axially located non-circular bore closed at said one end and open at said other end and providing a readily accessible hand tool receiving dowel turning socket capable of permitting the dowel to be unscrewed and bodily removed from said fitting when necessary or desired, and complemental adapter means integral with said other end and projecting axially beyond said other end and said flange and embodying a reduced externally screw-threaded plug-like adapter which has an axial bore aligned with said first-named bore and is capable of being aligned with and screwed into the aforementioned screw-threaded hole.
Claim 2
Dependent Claim
182 words
For use in conjunction with an open-ended screw-threaded prescribed hole in a predetermined wall of a concrete mold: a positioning, setting and retaining device for a hollow internally screw-threaded fitting of a predetermined type designed and adapted to be embedded in a manner to serve as a bolt-holding anchor, said device comprising, a one piece plastic unit embodying an elongated externally screw-threaded rigid dowel closed at one end and having an outstanding integral wall abutting flange at its other end, said dowel being provided with an elongated axially located non-circular bore closed at said one end and open at said other end and providing a readily accessible hand tool receiving dowel turning socket capable of permitting the dowel to be unscrewed and bodily removed from said fitting when necessary or desired, and complemental adapter means integral with said other end and projecting axially beyond said other end and said flange and embodying a reduced externally screw-threaded plug-like adapter which has an axial bore aligned with said first-named bore and is capable of being aligned with and screwed into the aforementioned screw-threaded hole.
Claim 3
Dependent Claim
72 words
The positioning, setting and retaining device defined in and according to claim 1, and wherein said adapter means is provided at said flanged end with a reduced hollow flangible pressure responsive neck, said neck being interposed between said flanged end and plug-like adapter and having a lower end axially aligned with and integrally united with a contiguous upper end of said plug-like adapter and an upper end united with said flanged end.
Claim 4
Dependent Claim
33 words
The positioning, setting and retaining device defined in and according to claim 2, and wherein the bore of said plug-like adapter has its bore axially aligned with the hollow portion of said neck.
Claim 5
Dependent Claim
49 words
The positioning, setting and retaining device defined in and according to claim 3, and wherein said neck and plug-like adapter are cooperatively unified, said plug-like adapter being cylindrical in cross-section, and said neck being non-circular and of a cross-sectional dimension appreciably smaller than the cross-section of said plug-like adapter.
Claim 6
Dependent Claim
47 words
The positioning, setting and retaining device defined in and according to claim 4, and wherein said plug-like adapter has a leading end provided with an integral reduced socket member projecting axially beyond said leading end and which, when brought into use, constitutes a conveniently usable socket wrench.
