Abstract
An apparatus for facilitating the use of tools on underground pipeline systems including a socket having a polygonal open end, a pliable socket insert having a polygonal outer circumference corresponding to the polygonal socket opening adapted to fit snugly into the polygonal opening and flush with the open end of the socket and a locking device by which the socket insert is maintained within the socket during use. The socket insert is provided with a plurality of pliant inwardly extending projections which deform to the size and geometry of the tool to be employed when the socket is pressed onto the tool.
Claims19
An apparatus for facilitating the use of tools on underground pipeline systems comprising:
- a cap/tool holder having a cylindrical body closed off on a first end by an end wall, said end wall forming an end wall opening adapted to lockingly connect to a rotatable shaft, and said cylindrical body having an open second end, said open second end forming a polygonal opening;
- a pliable donut-shaped cap/tool holder insert having a polygonal outer circumference corresponding to said polygonal opening adapted to fit snugly into said polygonal opening and flush with said second end;
- said cap/tool holder insert further comprising a plurality of projections extending from an inner circumferential surface of said cap/tool holder insert into a centralized space formed by said cap/tool holder insert;
- and
- locking means for securing said cap/tool holder insert within said cylindrical body.
