ABSTRACT:
A connecting linkage is provided between two structural members which includes a pinned connection to allow rotation of one structural member with respect to the other and which permits adjustment and alignment before locking the device in position without the need for drilling a precisely positioned hole for the pin in the structural member. An oversized hole is formed in one of the structural members and the pin is placed through the hole. A first support plate having pin-sized holes is then placed over each end of the pin followed by a second pair of support plates also having pin-sized holes. The assembly is then moved with respect to the first structural member as permitted by the oversized hole around the pin into a desired position. The second pair of support plates are then welded to the second structural member and the first pair of support plates are welded to the first structural member. If desired, the pin may be welded to the second pair of support plates. The first pair of support plates and the first structural member are free to rotate about the pin and with respect to the second pair of support plates and the second structural member.
