Application Isa-fiery s, 1950, Serial No. 137,218
Claim.-
in ention relates to an apparatus for int-- rng eynnd i af objects. More part cuiafly, are-- later? to a ll tif-g device assisted to" be mounted on astandard lift truck as an accessory thereto which is operable to lift and transport rolls of paper or other heavycylindrical objects.
This applicationis a continuation-in-part of our depending appficati'cn seriar No, 749,312, filed May 20, 1947, new Patentfio. 21,497,118, granted February 14, 1950, entitled Apparatus for Lifting Cylindrical Qbl'ectsff I It is an object of this invention to provide apparatus oil the character; and for the purpose described, which is si mple inits operation and which is also flexible, being capable of handling rolls of pape-r of different diameters.
Itis a further object of the inventiorr to provide apparatus of the character and for the purpose described, which is easily mounted on the boolnof a; standard lift truck and which is capable of lifting and transporting heavy rollsof paper or other heavy; cylindrical objects.
It is a still further object of the invention to provide apparatus of the character and for the purpose described which is operable hydraulically.
These and other objects of the invention will be apparent from the ensuing description and the appended claim.
Certain forms which the invention may assume are exemplified in the following description and illustrated by way of example in the accompanying drawings in which:
Fig, 1 is a top plan view of one form of apparatus adapted to lift and transport a pair of paper rolls.
Fig. 2 is a side elevation of the same.
Fig. 3 is a top plan View of a modified form of apparatus adapted to lift and transport a single paper roll.
Fig. 4 is a side elevation of the same.
Referring now to Figs. 1 and 2 of the drawings, the device there shown is designated generally as l0 and it is shown mounted on a standard lift truck designated as I l and having the usual telescoping boom 12. The apparatus comprises a centrally located, fixed double jaw I3 which is formed by two identical curved plates or sheets I4 of circular radius, each having an inner portion l5 of relatively large area and an outer tapered portion I6 of lesser area. A center plate I! is provided which is disposed centrally between the plates l4, and a shoe I8 is welded to the outer end of the center plate I1 and to the plates I 4. The plates M ar mounted on and firmly fixed to a rectangular frame H! by means 2 of vertical side plates or brackets 21], the center platel'! and horizontal brackets 2| and 22. The frame I9 is adapted to be mounted on the boom [2 of a lift truck, as by means of pins or bolts 23.
Outer, movabig jaws are provided by means of arms or levers 24, each of which is pivotally supported on a vertical pivot pin 25 carried by the brackets 2 j and 22", and at its outer end each arm 24; is provided with a shoe 2? formed of a curved plate 28' having holes 28" and a web 3&3. The shoe 21 is mounted on a vertical pivot pin 3|. The plate 28 preferablyha's a circular radius and the purpose of the holes 2?" is to break suction between the shoe anda' roll of paper indicated at 33, whenever it is desired to' release the roll of paper;-
For the purposeof operating the arms 25 a pair of double acting cylinders 34 are provided, one for-each of the arms 25." Each. cylinder 34 is piv otally mounted upon a pivot pin 35 and is con-- nected to its arm by means of a rod 36. Fluid pressure linesfiil and M? are provided for operating the cylinders 3'4. An'hydrauliccircui't indicated generally at Al is provided, comprising a pump 42, a reservoir 43, a valve 44 and communicating lines 45.
In operation, the lift truck I I is manipulated so that the central fixed jaws approach and contact a pair of paper rolls or the like with the shoe l8 disposed therebetween. It will be seen that the smooth, wedge-shaped contour of the shoe l8 will guide the central jaws between a pair of adjacent rolls without the necessity of moving them apart.
Meanwhile, of course, by appropriate control of the valve 44 the arms 25 will be pivoted outwardly so that they and the shoes 27 will clear the rolls. Thereafter the valve 44 will be manipulated to pivot the arms 25 inwardly and to bring the shoes 21 into firm contact with the rolls. Hydraulic pressure is then held in the cylinders 34 while the lift truck is operated to elevate or lower the rolls as desired and to transport the rolls.
Referring now to Figs. 3 and 4, there is shown a simple form of apparatus adapted to handle a single roll. The apparatus is generally designated as 45, and it is shown as being mounted on a lift truck 46 having a boom 41. The apparatus comprises a single fixed jaw 38 formed by a plate 49 of cylindrical contour comprising an outer section 50 of greater area and an inner tapered section 5| of lesser area. The plate 69 is fixed by means of vertical brackets 52 and 53 and horizontal brackets 55 and 56 to a rectangular frame 51 which may be mounted on the boom 47, as by means of bolts or coupling pins 58.
A movable jaw is provided by means of an arm 59 which is pivotally mounted on a pivot pin 60 extending through the arm and through the brackets 55 and 56. At its outer end the arm 59 is pivotally connected by a pivot pin Bl to a shoe 62 formed by a web 63 and a curved plate 64. The plate 54 is formed with suction-breaking openings 65, as illustrated.
At its inner end the arm 59 is connected to a double acting cylinder 66 by mean of a rod 61. The cylinder 66 is pivotally mounted on a pin 68 and is provided with fluid pressure lines 69.
In operation, this form of apparatus is employed similarly to that of Figs. 1 and 2. A detailed description of operation is unnecessary in view of the description of operation of the apparatus of Figs. 1 and 2.
It will be apparent that most of the advantages provided by the apparatus of Figs. 1 and. 2 are also provided by that of Figs. 3 and 4. The apparatus of Figs. 3 and 4 is adapted to handle only a single roll, but in many instances this is sufficient and the device is of lighter, simpler construction.
It will therefore be apparent that a novel form of lifting device is provided which is readily mounted upon a standard lift truck and which constitutes an accessory therefor. In one of its forms, the apparatus is adapted to handle a pair of rolls and in another form, a single roll. Both embodiments are hydraulically operable to firmly grip and support a roll of paper or the like, and they are flexible, being operable to handle rolls of greatly varying diameter.
While we have shown the preferred form of our invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the appended claim.
Having thus described our invention, what we claim and desire to secure by Letters Patent is:
Lifting apparatus of the character described,
comprising a pair of cylindrical plates arranged in side-by-side relationship and constituting a pair of fixed, inner jaws each adapted to encompass and grip one side of a roll of paper, a frame adapted to be mounted on the boom of a lift truck, spaced outer plates each extending between and fixed to the central portion of one of the cylindrical plates and to one side of the frame, a central, vertical plate disposed symmetrically between said cylindrical plates fixed at one end thereto and at the other end to said frame, a wedge-shaped shoe fixed to the outer end of said central plate and to the adjacent ends of said cylindrical plates, a pair of spaced, horizontal brackets supported rearwardly of each said cylindrical plate, an arm mounted on a vertical fulcrum between each pair of horizontal brackets, a shoe pivotally mounted at the outer end of each said arm adapted to encompass and grip the opposite side of a roll of paper, a double-acting hydraulic cylinder pivotally mounted between each pair of horizontal brackets, and means operatively connecting each said cylinder With an arm to operate the latter.
