Device for attachment to a bridge support bracket

Abstract

A device for attachment to a bridge support bracket is adapted to be connected to an end of a support bracket horizontal component and to an end of a support bracket vertical component. The device comprises a support adapted to be attached to the end of the horizontal component, a sliding tube adapted to be attached to the end of the vertical component, and a mounting tube attached to the support for mounting the sliding for sliding movement relative to the support. A slot is in the side of the mounting tube, and a nub is attached to the sliding tube and extends through the slot. The nub has a threaded opening therein, and a threaded rod extends through and engages the threaded opening, the threaded rod being mounted for rotation but not vertical movement relative to the support, for moving the vertical piece vertically relative to the support.

1 . A device for attachment to a bridge support bracket, the support bracket including a horizontal component, a vertical component, and an angled component attached at one end to an end of the horizontal component, and another end of the angled component is attached to an end of the vertical component,
 the device being adapted to be connected to the other end of the horizontal component and to the other end of the vertical component, the device comprising:   a support adapted to be attached to the other end of the horizontal component,   a vertical piece adapted to be attached to the other end of the vertical component,   mounting means attached to the support for mounting the vertical piece for sliding movement relative to the support, and   moving means attached to and between the support and the vertical piece for moving the vertical piece vertically relative to the support.   
     
     
         2 . The device in accordance with  claim 1  wherein the mounting means is a mounting tube, and the vertical piece is a sliding tube received in and slidable relative to the mounting tube. 
     
     
         3 . The device in accordance with  claim 2  wherein the moving means comprises a slot in the side of the mounting tube, a nub attached to the sliding tube and extending through the slot, the nub having a nub threaded opening therein, and a threaded rod extending through and engaging the nub threaded opening, the threaded rod being mounted for rotation but not vertical movement relative to the support, so that rotation of the threaded rod slides the nub and sliding tube relative to the mounting tube and the support to vary the combined length of the support bracket vertical component and the vertical piece relative to the horizontal component to change the angle of the horizontal component relative to the vertical component. 
     
     
         4 . The device in accordance with  claim 1  wherein the support comprises two spaced apart support plates, and wherein the threaded rod is mounted for rotation relative to the support by the two spaced apart support plates, each support plate being located on opposite sides of the nub, with a threaded rod opening in each support plate, the respective ends of the threaded rod each passing through the respective plate threaded rod openings, and a threaded rod nut fixed to each respective end of the threaded rod for preventing sliding movement of the rod relative to the support, with at least one nut being adapted to be rotated to in turn rotate the threaded rod relative to the support. 
     
     
         5 . The device in accordance with  claim 1  wherein the vertical piece is adapted to be attached to the other end of the support bracket vertical component by having an attachment opening through one end of the vertical piece, and a bolt that passes through the attachment opening and through the other end of the vertical component in order to secure the other end of the vertical component to the end of the vertical piece. 
     
     
         6 . A device for attachment to a bridge support bracket, the device being adapted to be connected to an end of a support bracket horizontal component and to an end of a support bracket vertical component, the device comprising a support adapted to be attached to the end of the horizontal component, a sliding tube adapted to be attached to the end of the vertical component, and a mounting tube attached to the support for mounting the sliding for sliding movement relative to the support, the device having a slot is in the side of the mounting tube, and the device further including a nub attached to the sliding tube and extending through the slot, the nub having a threaded opening therein, and a threaded rod extending through and engaging the threaded opening, the threaded rod being mounted for rotation but not vertical movement relative to the support, for moving the vertical piece vertically relative to the support.
