Form panel supporting walers (32, 34) are secured in crossed relationship by an assembly having inner and outer right angle-shaped members (10, 12) engageable with opposite sides of the walers, and clamp means to draw the members toward one another. The clamp means comprise a bar (18) fixed to one of the members (10) and extending slidably through the other of the members (12), and a wedge (24) extending through the bar (18) for engagement with said other member (12).

Waler corner lock assembly

A tie rod assembly to secure form panel elements in edge to edge engagement and tie opposed panels made of such elements in spaced apart relationship. The assembly employs a tie rod having a length less than the distance between the opposed panels and gripper mechanisms releasably engageable with the ends of the tie rod and proportioned for extension through tie rod openings formed in the panels. Key elements are engageable with the gripper mechanisms and the panel elements to lock the mechanisms in engagement with the rod and secure the panel elements in place. The rod is provided with enlarged heads at either end thereof for engagement by the gripper mechanisms and, in a preferred embodiment, the sides of the head are flattened.

Tie rod assembly for concrete form panels

An earth working apparatus is disclosed including means for removably coupling a compacting roller into operative engagement with a hydraulically manipulated boom while simultaneously maintaining the excavating bucket of the apparatus in its operative association with the boom. The coupling means includes a specially designed link which connects the hydraulic means of the boom to the bucket and which is adapted to receive and engage the compacting roller upon upward movement of the boom.
