ABSTRACT:
A barrel grasping device with upper and lower jaws pivoted to a double yoke surrounding the pole of a barrel trolley. An auxiliary yoke imprisoning a clamping plate is slidingly mounted on the pole above a double yoke and is connected to the latter by a compression spring. A connecting rod is pivoted at one end to the double yoke and at its intermediate portion to a lever having one extremity pivoted to the auxiliary yoke around an off-set axis and engaging a clamping plate. The weight of the barrel transmitted by the jaws to the double yoke automatically pulls the connecting rod, causing the lever to pivot and push the clamping plate against the pole, thus clamping the device along the pole of the barrel trolley.
