35 will serve to stabilize clamp 10 once a wale has been clamped therein and will also serve as a location for the teeth of a tong clamp 42 as will be described in more detail hereinbelow bracket 14 has one longitudinal edge bent perpendicularly to form a short vertical wall 36 the opposite longitudinal edge 38 is bent slightly off horizontal in a direction opposed to short wall 36 as shown in the drawings these edges 36 and 38 allow bracket 14 to be inverted and used with various types and sizes of wales a pair of spaced apart apertures 40 are located adjacent short wall 36 and bracket 14 and are designed to receive the legs of a conventional tong clamp 42 for holding a vertical wale as will also be described in more detail hereinbelow handle 16 has a cam 44 at one end and is pivotally connected to the vertical wall 18 of main body 12 cam 44 on handle 16 pivots around a bolt 46 which projects perpendicularly from vertical wall 18 a nut 48 fastens the handle 16 on bolt 46 cam 44 has a pair of opposed cam surfaces 50 which are arranged on cam 44 so as to engage a wale when handle 16 is moved from a vertical position to a horizontal position the use of two opposing cam surfaces 50 allows the handle 16 to be moved in either direction to engage and clamp a wale under one of the cam surfaces 50 to align the form panels.
