Claim 2

A closet flange on which a water closet is adapted to be mounted, said flange having bolt slots in which bolts are inserted in inverted positions for securing said closet in place, each of said slots being wider at one end for initial insertion of a bolt and having a width at the other end substantially the same as that of the diameter of the bolt, the slot having an inwardly directed feathered edge at said other end of a dimension to require the bolt to be pressed therein so that a fit for the bolt is provided at said feathered edge sufficient to sustain the bolt in place.

Claim 3

The closet flange that is defined in claim 1, wherein said feathered edge is an extension of one planar surface of the closet flange.

Claim 4

The closet flange that is defined in claim 1, wherein said closet flange is molded of organic plastic material.

Claim 5

The closet flange that is defined in claim 1, wherein said feathered edge is corrugated.

Claim 6

The closet flange that is defined in claim 4, wherein the corrugated feathered edge has smoothly radiused peaks and valleys.

Claim 7

An article of manufacture for use as a water closet flange comprising an integral one-piece fitting molded from organic plastic material, said fitting including a tubular portion having a radial flange projecting outwardly from its upper end, said radial flange having bolt holes on diametrically opposite sides for passage of the heads of bolts and short circumferentially directed slots of narrower dimension in communication with said bolt holes for accommodating the stems of the bolts, said radial flange having relatively thin inwardly projecting feathered edges at said slots of narrower dimension than the remainder of said slots so that the bolts can be pressed into the slots in an inverted position and the feathered edges will engage the stems of the inverted bolts to hold the bolts in place during assembly of the water closet on the closet flange.

Claim 8

An article of manufacture for use as a water closet flange comprising an integral one-piece fitting molded from organic plastic material, said fitting including a tubular portion having a radial flange projecting outwardly from its upper end, said radial flange having bolt holes on diametrically opposite sides for passage of the heads of bolts and short circumferentially directed slots of narrower dimension in communication with said bolt holes for accommodating the stems of the bolts, said radial flange having relatively thin inwardly projecting feathered edges at said slots of narrower dimension than the remainder of said slots so that the bolts can be pressed into the slots in an inverted position and the feathered edges will engage the stems of the inverted bolts to hold the bolts in place during assembly of the water closet on the closet flange.

Claim 9

The article of manuracture that is defined in claim 6, wherein the feathered edges are flush with the upper surface of said radial flange.

Claim 10

The article of manufacture that is defined in claim 7, wherein said feathered edges are corrugated so as to provide smoothly radiused peaks and valleys.
