more pressure is applied through the rod 12 which applies pressure to the trigger on the motor device not shown the bracket 13 furnishes a hinged cup useful to secure the rear of the motor of the portable drive device such as a drill in place a locking mechanism 26 is mounted onto the bracket 13 and securely holds the hinged bracket 13 in a closed position when the portable drill etc is applied in place for furnishing a rotary drive force the second bracket 14 prevents any lateral shifting or movement to the drill and its motor once installed in other words it holds it firmly in position the assembly 25 is attached to the tube 7 through its various plates as previously explained and as further previously reviewed this also attaches and directly communicates the operator for steering purposes through the sleeve 7 directly to turn and steer the wheel 22 during usage with one hand on the grip the operator can easily turn the assembly 25 which turns the drive wheel and allows the scaffold to be guided left or right or forwardly or in reverse for steering purposes when throttle power is applied as can further be seen in fig1 a horizontal stabilizing bar 27 a is secured into position to hold the front casters parallel to the scaffolding and prevent the casters from being able to move 360 u00b0 this bar is easily installed by removing of the casters sliding the vertical columns 1 through the holes of the bar 27 and which thereafter the casters are reinstalled in place the bar 27 is dropped down upon the casters and the channels at the end of the bar 27 secure the casters in a reasonably fixed direction this provides directional.
