Clamping lock for looped ties

In a form for settable casting compositions having first and second opposing walls;

• each of said walls being comprised of a plurality of interconnected panels;
• said panels having substantially rectangular facings;
• metal rails attached to the perimeters of the facings;
• said rails having a pair of contact flanges and a web between the flanges;
• tie notches formed in the contact flanges of the rails;
• said tie notches being uniformly spaced so that when a pair of adjacent panels are interconnected to form a first wall of the form, the contact flanges of the rails on adjacent sides of the panels substantially are in contact with one another, the adjacent tie notches substantially form tie slots;
• the panels forming the second wall of the form being positioned so that pairs of tie slots formed by the rails of adjacent panels are substantially aligned with corresponding pairs of tie slots of the first wall;
• and a looped tie having loops at each end positioned within the aligned tie slots with the loops of the tie extending beyond the ends of the rails, a clamping lock engaging the loops of the tie;
• the improvement in the clamping lock comprising in combination:
• a pair of clamping members, each member having a base and a jaw depending from each base, said clamping members being securable together and mounted astride a pair of rails of adjacent panels of a wall of the form with the rails between the jaws of the members;
• wall means on said bases for forming a tie loop passage having an axis of symmetry when the clamping means are secured together;
• means on said bases for removably securing said bases of the clamping members together to secure the clamping lock to the rails, to clamp the rails together, and to position the clamping lock so that the longitudinal axis of the tie loop passage is substantially aligned with the tie notches of the rails between the jaws;
• and
• tie fastening means having a tapered arm mounted on said members, said tapered arm being insertable in the loop of a tie extending beyond the tie loop passage to secure the loop to the members.

A clamping lock for securing a loop of a looped tie to a wall of a settable casting composition form having opposing walls, a plurality of panels being interconnected to form a wall of sid form, said panels having rails attached to their perimeters, the rails of said panels having pairs of contact flanges and a web, tie notches formed in the contact flanges through which a looped tie may extend, said clamping lock comprising:

• a pair of clamping members, each member having a base having wall means, the wall means of said base forming a tie loop opening when the bases are secured together;
• a jaw depending from each base;
• means on said bases for removably securing said bases of the clamping members together, said clamping members positionable on a pair of rails of adjacent panels so that the rails are between the jaws, the tie notches in the contact flanges form a pair of tie slots, and the clamping lock is positioned on the rails so that its tie opening is substantially aligned with the tie slots in the rails between its jaws;
• and
• tie fastening means pivotally mounted about a pivot axis on the base of one of said members, said fastening means having a curved tapered arm which is insertable into the loop of the looped tie protruding beyond the tie loop opening to secure the loop to the clamping lock.

A clamping lock for securing a loop of a looped tie to a pair of panels of a wall of a settable casting composition form having opposing walls, said clamping lock comprising:

• a pair of clamping members, each member having a base;
• a jaw depending from each base;
• a tooth formed on each jaw, each tooth adapted to be inserted into a connector slot of a rail of a panel of the form, said rail including a contact flange;
• means on said bases for removably securing said bases of the clamping members together, said jaws of the clamping members adapted to be positioned astride a pair of rails of adjacent aligned panels so that the tooth of each jaw is inserted into one of a pair of opposed connector slots in the rails between the jaws of the members;
• wall means on the bases of said members when secured together forming a tie opening having a longitudinal axis, which axis is adapted to be substantially aligned with the centers of a pair of tie slots formed when the contact flanges of a pair of rails of aligned panels are in substantial contact, and having this position when the teeth of the jaws are inserted into a pair of opposed connector slots of a pair of rails by securing the bases of the clamping members together;
• bearing surfaces formed on the bases of the two members, said bearing surfaces when the members are secured together being substantially coplanar;
• an anchor lock having a shank and a curved arm attached to the shank, the shank of said anchor lock being pivotally mounted on a bearing surface of a base of one member for rotation about a pivot axis, the arm of the anchor lock being wedge shaped and lying on an arc having its center on the pivot axis, the arc of the arm of the anchor lock substantially intersecting the longitudinal axis of the tie opening;
• whereby the arm of the anchor lock is adapted to be inserted into the loop of a looped tie extending through the tie slots aligned with the tie opening with at least a portion of the loop extending beyond the bearing surfaces of the bases of the clamping member.
