Abstract
Abstract An improved device for securing a toilet to a soil pipe flange includes a flange fastening nut comprising a guide member and a retaining member connected by a shaft for slidably engaging a slot in the flange, the guide member being above the slot for guiding an opening in the base of the toilet into proper position over the fastening nut, the guide member including a tapped hole into which a bolt may be screwed from above the base of the toilet to secure the toilet to the flange. The invention may also be embodied in a soil pipe flange having a plurality of guide members each including a tapped hole fixedly attached to the upper surface of the flange in positions matching the openings in the base of the toilet.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
260 words
A nut for threadably receiving a fastening means for securing a toilet defining an oval opening therein to a soil pipe flange, said flange including a horizontally disposed annular ring defining an arcuate slot therein and including downwardly extending annular lips at the inner and outer edges of said annular ring forming a channel under said annular ring, said fastening means being positioned to engage said toilet and extend downwardly through said opening to bias said toilet against said flange, and said nut comprising: a vertically extending shaft having a diameter slightly less than the width of said arcuate slot and a length slightly longer than the thickness of said annular ring; a flat lower retaining member fixed to the lower end of said shaft; an upper retaining member defining a vertical tapped hole therein, and having a flat base fixed to the upper end of said shaft, said base having an oval perimeter, and said upper retaining member further defining an inclined guiding surface extending uniformly from the perimeter of said base upwardly to said vertical tapped hole; said lower retaining member and said base of said upper retaining member being parallel to each other and perpendicular to said shaft, said flange receiving said shaft in said arcuate slot, said upper retaining member holding said lower retaining member at least partially within said channel, and said oval base being shaped to be loosely matingly received by said oval opening in said toilet and extending upwardly within said opening in said toilet when said toilet is positioned on said flange.
Claim 2
Dependent Claim
