. 1 V, This invention relates to an industrial truck of the elevating type, and more particularly re lates' to trucks adapted for handling a plurality of barrels,-rol1s of paper, or the like.

To handle groups of upended barrels or the like it has heretofore been necessary to employ pallets or elevated platforms on which the barrels were placed before lifting the group with a fork truck. Such a system is cumbersome and is generally unsatisfactory. Therefore, it is an object of this invention to provide a method and means for handling groups of barrels without employing the pallets. A further object of the invention is to provide an elevating truck'in which the elevating member is of a modified form adapted to engage and lift loads comprising upended cylinders such as barrels or rolls of paper in groups or clusters. Another object of the invention is to provide an elevating or lift truck having an improved load engaging means adapted to engage the load at its lower central surface and at its upper peripheral surface.

'In general the objects and advantages of my invention are attained by providing a lift truck with an elevating member to which a depending mast is fixed. The lower end of the mast is adapted to be extended laterally and engage the bottom of one or more barrels. An upper barrel restraining frame is movably carried by the elevating member and the depending mast passes slidably through the frame member. Adjustable barrel restraining means are movably carried by the frame and these restraining means are adapted to engage the outer periphery of the top of the load at a point remote from the depending mast which supports the bottom of the load.

These and other features of my invention will become apparent to those skilled in the art to which this invention relates from the following description taken in connection with the accompanying drawings wherein:

Figure 10 is a top view along the line I ll-l0 The present invention is particularly adapted for lifting cylindrical containers in groups of 3 or i and for transporting them without the necessity of employing pallets. By the term cylindrical container I mean to include in addition 'to drums, barrels and the like, rolls of paper and other generally cylindrical units. As will be understood from the following description, my invention is particularly adapted for the handling of sheet metal drums.

In brief, my invention comprises a hydraulic lift truck including a truck chassis Ill operated on wheels II and adapted to be controlled by an operator through control levers l2. At one end of the truck is a vertical guide frame 13 supporting a movable elevating frame l4 which carries the adjustable load engaging mechanism described in considerable detail below.

The elevating frame I 4 projects from and is slidably mounted on the guide frame [3 and. can be moved vertically thereon by the usual hydraulic elevating mechanism provided on such truck frames and not shown in detail. The adjustable member 15 includes the movable jaws It to grip the outer periphery of a cluster of barrels l1 and a lower load engaging means in-' cluding extendable lugs I8 carried by the depending mast l9. The restraining jaws H; which movably extend through the frame l5 are operated by hydraulic cylinders 21. The mast l9 passes through collar 20 in the restraining frame: [5 and enters the space Ila between groups of Then the frame I5 and periphery barrels l'l. engaging means 16 are hydraulically lowered toward the cluster of barrels H. are extended laterally under the barrels and then the lift member [5 is lowered further onto the top of the barrels and the jaws I6 brought into peripheral contact with the load. The barrel is thereby suspended at three points, i. e. the lug It at the bottom and the load engaging jaws 16 at the top. The entire load thus secured can then be raised upon the elevating frame 14.

The lugs .18 v

' 3 Alternatively, to avoid lateral movement of the load upon extension of the lugs I8, I may first apply some restraining action to the top of the load by operation of the restraining jaws I6.

In the operation of handling barrels with the apparatus described, 3 or 4 barrels of one or more sizes or shapes can be handled whether they be full barrels "and. half barrels'and :cylin'drical tor bulged. -In-the illustrated embodiment 4 barrels IT to be transported are arranged in clover-leaf pattern as shown in Figures 2 and 3 and disposed on the plane surface, preferably .withthe sides of the barrels in contact as shown in'Figure 3. However, the peripheralrestraining jaws I6 can be used to shift the :barrelsjdnwardlymo as to assume the described arrangement. If the number of barrels is lessthan .4 their locations should be those which would result if'there were 4 barrels arranged in the described -pattern. In other words, the upper periphery engaging jaw -I 6 and the bottom support -means I 8;,inclependently1assume the {load engaging positionofFigures .1,r2, and 3.;for 3each barrel whether there be 1, 2, 3, or 4 barrels in the group.

The operator then lowers the barrel restraining frame I;5;a's.a unitawith rthe hoisting mechanism pf the elevatingrframe I4 until=the.lower ,end of the reenter post or;mast t9 comes to rest on the surface supportingthe barrels.

The lower carrying lugs I8-are extendedlaterally under the load-by the perationof hydraulic Cylinder; 22 which rotates the center "shaft .23 within the;tubular-:mast IQ.

"The barrel "engaging assemblyywhich includes the frame I5, the upper periphery restraining jaws or posts I6, "the -'center 'mast I9 and the knife-*edged lifting lugs I8, together :with their hydraulic operating "means, is lifted on the .ele-

With the barrels so held securely the truck is driven to the new location for the barrels and unloaded on a plane surface by reversal of the operations outlined above. In other words; the lifting frame I5 is lowered on the hoisting mechanism =I4 until the centerimast I9 .andtthe bottom'of the barrels Il are resting uponthe floor.

The restraining jaws I6 are moved laterally outa-ward and simultaneously the center shaft 23 within the .mast I 9 is rotated so as to retract the knife-edged lugs I8. The frame I5 can be raised :relativeito .the elevating frame I4 through the .rauxiliary supports 32B and the hydraulic lift 25 fixed to the-elevating frame I4 which can then be raisedusoas to withdrawn the center mast I8 before the truck assembly is driven to a new location.
