Application filed May 20, 1930, Serial No. 454,146, and in Germany November 23, 1828.

This invention. relates to a device com-. posed of a rod with one or two lifting plates fixed on its upper end, by means of which articles, such as boxes can be taken down from L5 and replaced on high places. The invention is characterized in that an automatically-operating gripping and holding device is fitted on the hfting plate. This gripping device holds the box or the like securely on the plate.

1 An embodiment'ofthe invention is illustr'ated by way of example in the accompanying drawings in which:

" Fig. l shows the lifting device with gripping and holding device in bottom plan view.

Fig. 2 is a section on line II-II of Fig-1; Fig. 3 is a side elevation of the gripping device.

Fig. 4 shows the arrangement of a griping device on a lifting device with only one ifting plate. Y Fig 5 shows in use. 4 1 According to the invention two pairs of levers 12, 12' and '13, 13' are arran ed underneath each lifting plate 2, 3 lin ed together, and act like gripping tongs. A downwardly directed pin 14 is arranged in each of the pivot pointsof the levers 12, 12' and 13, 13', whereas the lever ends 12" and 13'. laterally projecting over the lifting plates 2, 3 are provided with upwardly directed gripping pins 17. The gripping device has its stationary'fulcrum -on the lifting plates 2, 3 at 15. The levers 13 and 13' are connected the one with the otherby a pullspring 16. For guiding and holding perspective the device in thes movable levers-12,- 12' and 13, 13' on' the lifting plates 2, 3 suitable means, such as .gulde'bars 19, may be provided.

If the lifting plateis now inserted between two rows of boxes 6, -7 (Fig. 5), the

pin 14 strikes against thelower box 16 so' that the gripping device composed of levers 1s forced back, owing to its articulations and the'tpgeition shown in dotted'lines naequgntlv the up 1' box is" pnsh onto the lifting plate. f this box ulifted outofthemwbymeansotthetdeso vice, the gripping mechanism, owing to the of spring 18,agai n its ini' tial position, the gripping pins 17 pressing against the side walls of the box and hold same in its position on the lifting plate.

If it is'desired to put a box back into the corresponding gap in the row of boxes, the a;

same operation is repeated. The pin 14 "strikes against thc'box of the lower 'row, or againstthe edge of the shelf board, when no lower row of boxes exists, and presses the gripper pins 17 away from the box and by no inclining the lever plate, by means of the rod 1, the box is slipped into the gap.
