Application [July [22, 1955, a Serial No, 523,654 "1 Claim. (Cl. 214-653) This invention relates .to industrial elevating trucks of the rfork lift :type used for picking up loads transporting loads at elevated levels and stacking the loads in a selected manner, and more particularly to an attachment for 'such .trucks particularly adapted for .handling large paper rolls.

It is the principal ,object of tthis invention :torprovide an attachment of the character indicated above for handlingtpaper rolls which may be readily installed with a minimum of modification oftthe :truck structure and which wi ll eflectively and safely grip large rolls of paper so as to transport the same without damage thereto, .from one place to another, stack the rolls in a prescribed manner, and remove the rollsfrom the stacks. 1 The above and other objects are attained by employingthis invention'which embodies among its features, an attachment for handling paper rolls for :use with an -industrial elevating truck of the type having spaced upstanding'elevatorguides and an elevating means associated with the guides, the attachment comprising an upstanding elevator mounted on the guides for vertical movement therealong and operatively connected to the elevating means, paper roll supporting rollers mounted on the elevator for movement toward and away from each. otherto grip paper rolls therebetween whenmoved toward each other and -to release rolls whcnmovedaway from each other, and means on the elevator and operatively connected to-the rollers to move them toward and away from-each other.

*Other objects and advantages will become apparent from .a consideration of the following detailed description, formingthe specification, and :taken in conjunction with the accompanying drawings, wherein:

Figure 1 is a fragmentary side elevational :view ofythe forward portion of an industrial elevating xtruck showing an attachment embodying this invention installed thereon; t

Figure 2 is a front elevational view thereof;

Figure 3 is an enlargedcross sectional view taken substantially along 'line 3-43 of Figure ,2 and looking in the direction of the arrows;

Figure 4 is an enlarged cross sectional view through one of the rollers taken substantially along line 4T4 of Fi u ,Figure Sis an enlarged cross sectional view taken along line .555 of Figure 4 and looking in the direction of the arrows; and t Figure 6 is .an end elevational view of a stackof paper rolls showing the manner in which the paper roll supporting rollers maybe associated with the paper rolls in the stack.

With continued reference to the drawings, the forward portion of an industrial elevating truck of the fork lift type, generally indicated 10, has a pair of spaced, vertical elevator guides 12 at the front end thereof and between the front steerable wheels 14 of the truck. The truck has a conventional elevating means, generally indicated at 16, which is shown as of the hydraulically Patented Dec. 25 1956 operated type, and which is associated with the elevator guides.

The illustrated attachment embodying this invention is generallyindicated'at 18, and comprises an upstanding frame -20 ,ofrectangular form. The frame 20 has spaced parallel sideplates 22, a vertical bottom plate 24 extending therebetween and connected to plates 22 at their rear edges and an angleiron top bar 26 connected at its opposite :to the :top ends of the side plates 22 and extending ttherebetween.

As :showndn Figure 3, an intermediate vertical plate 28 extends between the side plates with its lower longitudinal edge engaged with the upper edge of the bottom plate 24, and is secured thereto by any suitable means.

A vertical plate 30 extends between the sideplates 22 and between the lower edge of the vertical flange 25 of the top bar '26 and the upper edge of the intermediate plate28tand has side flanges 32 extending perpendicularly andtrearward lytherefrom toward the guides 12 at oppos'ite .endsuof :the support plate 30. Vertically spaced pairst-ofzupper .and' lowerwheels 34 and 35 arerot atably mounted \ontheouter'sides of the side flanges 32 and ride in-the-channels of the elevator guides 12. 'Theelevating means 16 is operatively connected to the frame 20 adjacentthe 'lowertend thereof and to the bottom plate 24, as ;at.j3q6, :so :thattupon operation of the elevating means 16, thefram'e '20 ;will be raised or lowered. through the Qperationofaconveniently disposedtoperating handle '38 on the truck '10.

vA pair of :Lshaped arms, generally indicated at 40 and 142 respectively are mounted on the frame 20 for movement crosswise of the frame and are mounted on vertically spaced :transverse guide rods 44 and 45 extending between the side plates and passing through the vertical portionstls of the arms .40-and 42; As shown in Figure $4, the horizontally extending portion 50 of each 10f the;arrns 1,40 and 42 projects forwardly. Tubular rollers 52 are ibored longitudinally to rotatably engage on the horizontal portions 50. Anti-friction bearings '56 and 358 are interposed between the roller 52 and the horizontal portion of each arm adjacent opposite ends of the roller {to permit free rotation of the roller about the horizontalportions '50. 'It will be noted that the bores 54 of zthe :rollers 52 are provided with annular recesses 60 311C162 adjacent opposite ends thereof in which the bearings56tand'5'8 .are seated. Also, the portion 59, as shownjin Figure4, is :reducedtin diameter from a point adjacent to the vertical portion 48 to a point adjacent to its free end so as to provide a stop shoulder 64 against which :theantil-friction"bearing 56 is engaged against endwise movement and maintained in its recess 60.

At the free ends of the horizontal portions 50, are bearingstop washers 66 secured to the free end of the horizontallportion bya nut 68 bearing thereagainst and threadedly received upon a reduced diameter stud 70. This .was'her 3.66 bears against one endof the anti-friction bearing 58 to prevent endwise movement thereof and to maintain the bearingr5'8 in its recess 62.

Means :are provided on the frarne 20 for moving the arms 40 and :42 and consequently the rollers 52, crosswise of the frame 20 toward and away from each other whereby 18. large roll 72 of paper may be gripped ibe- 3 40. A hydraulic fluid conducting line 80 leads from a source of hydraulic pressure commonly associated with the truck to the end of the cylinder remote from the end secured upon theside plate 22 and, selectively operable valve handle 82 is mounted at a convenient location on the truck 10. A second hydraulic fluid conducting line 84 is also operatively associated with the source of hydraulic fluid pressure (not shown) normally associated with the truck 10 and leads to the opposite end of the hydraulic cylinder 74, so as to be in communication with the interior thereof. The line 84 is selectively controllable by a conveniently disposed valve handle 86 mounted on the truck 10 adjacent the handle 82. Hence, by selective operation of the handles 82 and 86, the arm 40 may be moved transversely of the frame along the guide rods 44 and 46.

Similarly, a lower horizontal hydraulic cylinder 88 has one end thereof secured to the side plate 22 opposite to the side plate on which the cylinder 74 is mounted and extends perpendicularly therefrom toward the opposite side of the frame 20. The operating piston rod 90 of the cylinder 88 projects longitudinally therefrom and has its free end secured to the upstanding or vertical portion 48 t toward each other and thereby lift the paper roll 72. It

will be noted that the rollers can accomplish this since they are free to rotate about their longitudinal axes without causing damage to the paper rolls therebeneath. When the rollers 52 have been separated to the extent that the paper roll 72 is cradled in the space therebetween and supported on the rollers, the elevating mechanism of the truck can be actuated to lift the paper roll 72 from the stack and remove it therefrom. Thereafter the paper roll 72 can be transported to any other desired location.

Also, as shown in Figure 6, where it is desired to stack paper rolls 72, the endmost paper roll 72" of the stack is placed upon the floor 100 or other similar supporting surface, in the manner hereinbefore set forth and the rollers 52 withdrawn by moving the truck rearwardly so that the paper roll will be deposited at the location desired. Subsequent paper rolls 72 may then be placed by continued operation of the truck' and 10 and the frame 20 and with the rollers on the arms 40 and 42 to complete the positioning of the other paper rolls.

In placing subsequent layers of paper rolls 72 upon a lower layer, it will be noted that the rollers 72 may be withdrawn from the stack through the spaces between upper rolls and lower rolls in the stack.

While there is shown and described the preferred embodiment of the invention, it is to be understood that the structure is susceptible to change and modification with- I in the practicability of the invention and therefore should upon the side plate 22. Thus, the cylinders 74 and 88 may be simultaneously operated by selective operation of the handle 82. The end of the cylinder 88 remote from the end having the connection with the hose 94 is interconnected into the line 84 by a flexible hose 98 which is in communication at its opposite ends with the line 84 through a suitable fitting and with the interior of the cylinder 88 adjacent its end secured to the side plate 22 at its other end. Therefore, by actuation of the handle 86, the arms 40 and 42 may be moved simultaneously in the opposite directions.

In operation, the truck 10 having been moved to a location at which it is desired to pick up a roll 72 of paper, and to transport the roll to another location, and the frame 20 being in a depressed position, the arms 40 and 42 are moved away from each other so that the rollers thereon will straddle opposite longitudinal sides of the roll. The hydraulic cylinders 74 and 88 are then actuated by means of the valve handles to move toward each other and into contact with the opposite sides of the paper roll adjacent the floor or other surface upon which the paper roll rests. As soon as the rollers 52 make contact with opposite sides of the paper roll to be lifted, the elevating mechanism 16 can be actuated and the paper roll lifted to the desired height along the elevator guides 12. The paper roll can then be transported to the desired location, the elevator means actuated to lower the frame 20, and the rollers 52 separated to deposit the roll at the desired location.

As shown in Figure 6, if it is desired to remove a paper roll 72 from the top of a stack of paper rolls, the rollers 52 are brought into close side by side relation and elevated to the required height so that upon forward movement of the truck, the rollers will move into the spaces between the bottom of the top roll 72'. The rollers are then moved be limited only by the scope of the claim appended hereto.

What is claimed is:

In a lift truck, a truck body having a forward end, a pair of laterally spaced vertical guides fixed on said forward end, elevating means on said body extending forwardly therefrom, a vertical frame in front of and extending between said guides and operatively connected to said elevating means for vertical movement along said vguides, said frame having laterally spaced vertical side plates, upper and lower guide engaging means on said side plates supportably engaging said guides, a pair of L- shaped arms having vertical portions and horizontal portions extending forwardly from said vertical portions, upper and lower guide rods in said frame extending between and secured to said side plates, said vertical arm portions being slidably supported on said guide rods for movement therealong, a pair of horizontal hydraulic cylinders each fixed at one end thereof to a related frame side plate and having a piston rod extending from its other end and secured to the vertical portion of one of said arms, and hydraulic actuating means severally connected to the hydraulic cylinders and operable to move said arms individually crosswise of the frame and toward and away from each other, said horizontal portions of the arms having rotatable tubular cylindrical rollers journaled longitudinally thereon.
