Abstract
A pocket former having a body with a tapered exterior surface. The body has a top surface and a bottom surface and a tubular member extending therethrough. The top surface extends outwardly from the tubular member for a greater distance than the bottom surface. The top surface and the bottom surface define a pocket therebetween. The top surface tapers to the bottom surface. The pocket has a generally semi-circular configuration at one end with a top surface forming a linear edge of the semi-circular configuration. The pocket has another portion of generally circular configuration. A plurality of radial struts extend from the tubular member to the top and bottom surfaces.

A pocket former comprising:
- a body having a tapered exterior surface, said body having a top surface and a bottom surface, said body having a tubular member extending therethrough, said top surface extending outwardly from said tubular member for a greater distance than said bottom surface extends outwardly from said tubular member, said top surface and said bottom surface defining a pocket therebetween, said top surface having an elongated length greater than a length of said bottom surface, said body having sides tapering to said bottom surface.
A pocket former comprising:
- a body having a tapered exterior surface, said body. having a top surface and a bottom surface, said body having a tubular member extending therethrough, said top surface extending outwardly from said tubular member for a greater distance than said bottom surface extends outwardly from said tubular member, said top surface and said bottom surface defining a pocket therebetween, said pocket having an end with generally semi-circular configuration, said top surface forming a generally linear edge of said semi-circular configuration, said linear edge having a length of between four inches and seven inches.
A pocket former comprising:
- a body having a tapered exterior surface, said body having a top surface and a bottom surface, said body having a tubular member extending therethrough, said top surface extending outwardly from said tubular member for a greater distance than said bottom surface extends outwardly from said tubular member, said top surface and said bottom surface defining a pocket therebetween, said body comprising:
- a first portion having a generally circular configuration, said circular configuration extending around said tubular member, said circular configuration including said bottom surface;
- and
- a second portion having a generally semi-circular configuration, said second portion having a generally linear edge with a length of not less than four inches, said linear edge being said top surface, said second portion having curved sides extending to said first portion.
