  • Patent number: 5042962
    Abstract: A hand truck particularly adapted for the movement of extremely heavy barrels has a wheeled base platform to which is pivotally attached a barrel holding frame having a forward vertical position and a braced reclining position against the truck. The barrel frame has its pivot point located at a sufficiently forward and low position so as to achieve approximately a ninety to one lever arm from the truck handle to the pivot point. The barrel frame has two lower barrel holding hooks. A pivoted barrel grasper, a lever arm having a pair of offset, facing grabber hooks, is positioned by means of a moveable pivot pin so as to engage the top lip of a barrel. In use, the barrel truck is moved in the erect position adjacent to a barrel; the grasper is positioned so that the grabber hooks enclose the upper rim of the barrel.

  • Patent number: 4895097
    Abstract: An apparatus for visually indicating to a driver of a towing vehicle the deflection of a pneumatic tire on the towed vehicle. A base member is mounted to the body of the towed vehicle in the proximity of the tire. A spring arm having a rotatable signal device of contracting colors is pivotally attached at one end to the base. A clip for releasably retaining the spring arm in a downward position in close proximity to the surface of the roadway is also attached to the base. Upon deflection of the tire the tip of the spring arm contacts the surface of the roadway which causes the spring arm to be released from the clip and move into a signaling position, extending outwardly from the towed vehicle and perpendicular to the direction of travel.
