Abstract
Abstract A portable, reusable aligning and retention device for use with stem panels in the forming of the stem portion of concrete foundations for residential structures and other small buildings is shown. The device employs spaced channels with cross-bracing. The channels fit over the top edges of the stem panels, which are plywood panels deployed in verticle position to form the sides of a concrete stem projecting upwardly from a concrete footing. The use of the device on the stem panels dispenses with the necessity for using nails and wooden bracing to hold the stem panels in the proper attitude of use. A ruled standard for use in conjunction with sighting lines is also provided to assist in the alignment of the stem panels.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
A reusable concrete form device for aligning and temporarily retaining stem panels, which stem panels define the vertical sides of a concrete foundation form, said device comprising in combination: a. two pairs of U-shaped channel members, each said pair including two U-shaped channel members connected together to form a 90* angle, each said channel member including a central section having an inner side and an outer side, first and second legs depending from opposite sides of said central section, each said channel membeR engaging an edge of at least one of the stem panels with said first and second legs extending along either side of the stem panels; b. a plurality of braces secured to said center side of said central sections of each of said pair of members for aligning corresponding members of said two pairs in a parallel relationship, whereby the stem panels retained by each said member of said two pairs are spaced to define the vertical walls of a right angle corner for the concrete form.
Claim 2
Dependent Claim
170 words
A reusable concrete form device for aligning and temporarily retaining stem panels, which stem panels define the vertical sides of a concrete foundation form, said device comprising in combination: a. two pairs of U-shaped channel members, each said pair including two U-shaped channel members connected together to form a 90* angle, each said channel member including a central section having an inner side and an outer side, first and second legs depending from opposite sides of said central section, each said channel membeR engaging an edge of at least one of the stem panels with said first and second legs extending along either side of the stem panels; b. a plurality of braces secured to said center side of said central sections of each of said pair of members for aligning corresponding members of said two pairs in a parallel relationship, whereby the stem panels retained by each said member of said two pairs are spaced to define the vertical walls of a right angle corner for the concrete form.
