摘要: Articles and methods for installing hook bolts on bridge decks constructed of timbers and structural steel members. A tether is lowered through a hole in a timber, captured below the bridge deck, and drawn upward around the timber or between timbers. A hook bolt is engaged with the end of the tether that was lowered through the hole and drawn upward, then lowered under the bridge deck and drawn upward through the hole in the timber. The hook bolt engages with a flange on a structural member of the bridge deck.

摘要: An improved fastener for attaching metal to wood is particularly suited for use as a railroad spike for attaching a metal rail to a wooden tie. The improved spike is adapted for installation by either driving or screwing the spike into the tie. A plurality of flutes are adapted to engage with the tie, thereby preventing loosening of the spike. The spike may be used with or without a metal boss or fishplate to secure a metal rail to a wooden tie.
