First Claim
Patent Images
1. A connecting device for a dowel bar and frame wherein the frame includes a U-shaped portion over the dowel bar and the frame also includes a horizontal cross-member, the connecting device comprising:
- a spring coil wire;
the spring coil wire comprising at least one circular member;
the at least one circular member forming a cavity;
wherein the cavity is capable of receiving the dowel bar;
the spring coil wire having a first and a second end;
wherein the second end has a hook for engaging the horizontal cross-member of the frame;
the spring coil wire further comprising section between the at least one circular member and the hook;
the section having a portion that extends substantially perpendicular to a longitudinal axis of the dowel bar;
the spring coil wire bendable whereby the second end can be selectively moved to disengage the spring coil wire from the horizontal cross-member.
