Abstract
Abstract The forms disclosed herein are intended for use in making porch foundations. The form is especially suitable for use with precast wall design. The forms are made up of two generally right triangular shaped side members each having a hook at one side of each of the right angles, suitable to be hooked over an existing foundation wall. One end of the form adjacent one of the acute angles is suitable to rest on a footing that supports the wall. A unique arrangement of the forms made up of an edge and clamp arrangement is provided which rigidly holds the side members together.

Claim 1
Independent Claim
348 words
A set of forms for a wing wall comprising a first side form, a second side form, and an end form, said side forms being generally in the shape of a polygon being generally in the shape of a right triangle having a generally right angle and two sides adjacent said right angle, a first edge of said forms adjacent said right angle being adapted to engage a wall of a building, the other edge adjacent said right angle extending out perpendicular to said wall, said end form being disposEd between said side forms and extending along a second edge between corners corresponding to two acute angles and adapted to extend from said wall outward and upward, a hook attached to each said side forms at said right angle, said hook being adapted to hook over the top of said wall, and means to hold said side forms together, each said side comprises at least one sheet of material and a plurality of angle members, each said angle member having one leg thereof lying against a said sheet and another leg thereof extending outwardly from said sheet, said angles on each said sheet comprising a first angle member, a second angle member, a third angle member and a fourth angle member, said first angle member extending along said first edge and being flush with said first edge, said second angle member being flush with said second edge, said third member being flush with said top edge of said sides, a fourth angle member is attached to each said side, said fourth angle member extending across said second acute angle from said top edge to said second edge, generally perpendicular to said top edge, a clamping member is attached to said sides at said fourth edge and extending between said sides, said clamp comprising a first hook member and a second hook member, said hook members being hooked over said sides, each said hook member having a platelike portion generally parallel to the other said platelike portion, and a wedge-shaped key extending through said platelike portions holding them together.

The forms recited in claim 1 wherein said end form extends upwardly outside said clamp member, and said clamp member has a flat planar side generally parallel to said first edge of said forms.
Claim 4
Dependent Claim
260 words
A set of forms for a wing wall comprising a first side form, a second side form, and an end form, said side forms being generally in the shape of a polygon being generally in the shape of a right triangle having a generally right angle and two sides adjacent said right angle, a first edge of said forms adjacent said right angle being adapted to engage a wall of a building, the other edge adjacent said right angle extending out perpendicular to said wall, said end form being disposed between said side forms and extending along a second edge between corners corresponding to two acute angles and adapted to extend from said wall outward and upward, a hook attached to each said side forms at said right angle, said hook being adapted to hook over the top of said wall, and means to hold said side forms together, said means to hold said side forms together comprises a locater bracket assembly, said locater bracket assembly having spaced side plates, spaced tubes between said side plates, the ends of said tubes, each said tube being adapted to receive a pin, said plates being disposed in engagement with the inside surface of said sides, a pin extending through one of said tubes and through said sides, and a wedge key extending through a slot in one end of said pin and engaging a said side, said pin being adapted to extend through other of said tubes whereby said end form may rest on said tubes and have the inclination thereof adjusted.
