摘要： This invention relates to a novel combination tie end latch and reinforcing timber clamp characterized by bracket means mountable for tiltable movement about a transverse axis intermediate its ends on either a concrete form tie or tie-like connector projecting from the face of a pouring form wall or some appurtenance thereto, a shelf formed on the inside face of the bracket means at one side of its axis of tiltable movement shaped to receive and hold a timber and an adjustable push-rod carried by the bracket means on the opposite side of its axis of tiltable movement from the shelf, said push-rod being operative to tilt the bracket means and bias a timber resting against the shelf into tight reinforcing relation against the form wall or another similar timber upon movement thereof from its retracted position into extended position. The invention also encompasses a construction wherein one such clamp is provided with a tie-like connector projecting therefrom upon which a second bracket is mounted as a clamp for a second timber. Included within the invention is a novel latch means comprising a keyslot in the bracket means adapted for detachable connection to the end of a form tie or other pin-forming element and a stop associated therewith that prevents the release of said detachable connection under load.
