Abstract:
1. A retainer apparatus for retaining a form mold on a surface, the form mold includes a front form, a back form, and a face form, wherein the front, back, and face forms are all parallel to one another along a form mold lengthwise axis, said retainer apparatus comprising: (a) a planar beam having an “L” shape disposed within a first plane, said planar beam having a longitudinal axis and an approximately perpendicularly positioned riser axis, wherein said longitudinal axis and said riser axis are both positioned within said first plane, said planar beam including a leg end portion, an opposing riser end portion, and a transition portion positioned therebetween said leg end portion and said riser end portion, said transition portion has a means to removably engage a portion of the face form and said riser end portion including a means for removably engaging the back form; (b) a foot extension that is slidably coupled to said leg end portion, wherein said foot extension has slidable movement within said first plane and along said longitudinal axis, said foot extension structurally allows a selectable lengthening of a first distance from said riser end portion toward said foot extension along said longitudinal axis, said foot extension terminates in a means for removably engaging the front form; and (c) an arm that is rotatably coupled to said riser end portion, said arm having rotatable movement within said first plane, said arm has an open operational state and a closed operational state, said arm closed operational state retains an opposing portion of the face form in position against said transition portion, said arm open operational state operationally facilitates removal movement of the face form from said retainer apparatus.
