Abstract A tie-down apparatus having a double anchorage clamp for metal straps, cables, chains and the like in tying down a house trailer or materials such as pipe, tubing and lumber having a U-shape body member with a pair of bolts extending through bores in the body member; one of the bolts having a slot extending axially from the threaded end portion and terminating adjacent the other for receiving a tie-down strap and the other bolt having a radially disposed opening at its mid-portion for receiving a cable. On the outer surface of body member adjacent the bores are shoulder members which abut against the head of the bolts to prevent the rotational movement of the bolts and a locking lever plate having two openings receiving the heads of the bolts. The locking lever plate being used as both a tool to rotate the bolts and as a restraining member for preventing the rotation of the bolts when placed over the head of the bolts. The ends of the tie-down strap or cable extend to and are secured to a pair of locking brackets which are adapted to be mounted on the undercarriage of the trailer. Upon rotating the bolt with the locking tool, the strap or cable becomes tightened about the trailer.
A tie-down apparatus comprising an anchorage clamp for receiving straps in tying down house trailers and the like having a base member, upwardly extending leg portions in substantially parallel and spaced relation mounted on said base portion, said leg portions having a pair of aligned bores, a threaded bolt having a head portion extending through said bores, shoulder means mounted on the outer surface of one of said leg portions engaging said head portion for preventing the rotation of said bolt, said bolt having a slot extending from one side to the other side along the axis of said bolt, said slot commencing at the threaded end of said bolt and terminating beyond substantially the mid-portion of said bolt for receiving a metal tie down strap and means securing said base member, said leg portions having a second pair of aligned bores, a second threaded bolt having a head mounted on said last named bores, further shoulder means mounted on said one of said leg portions engaging said head of said second threaded bolt, said second threaded bolt having a radially disposed opening at substantially the midportion thereof and a locking bracket adapted to be mounted on a frame of the house trailer having a U-shaped base member, bolt means extending from said base member and secured to said frame, a locking plate having slotted portions along opposed edges thereof for receiving the free end of said strap and means securing said strap between said locking plate and said base member and preventing the slippage of said strap therebetween.
