(Cl. 29490) This invention relates to a device for gripping and retaining objects and more particularly to a barrel grab assembly for a fork lift vehicle.

It is the object of the invention to provide an improved barrel grab assembly which is mountable on the carriage of a fork lift vehicle and engageable with opposite sections of a barrel to grip the barrel whereby upon upward movement of the carriage the barrel is moved to a raised position.

Another object of the invention is to provide a barrel grab assembly having barrel engaging jaw units which are pivoted on reversely inclined axes and are axially adjustable to accommodate barrels of varying sizes.

A further object of the invention is to provide a fork lift vehicle with a barrel grab assembly which is operable to automatically receive and release a barrel in response to forward and reverse movement of the vehicle.

Still another object of the invention is to provide a barrel grab assembly which is readily mounted on and detachable from a carriage of a fork lift vehicle.

Another object of the invention is to provide a barrel grab assembly for a fork lift vehicle which is capable of handling a pair of barrels.

An additional object of the invention is to provide a versatile barrel grab assembly which has a minimum number of movable parts and which is sturdy in construction and reliable and efficient in use.

The exact nature of the invention as well as other objects and advantages thereof will be readily apparent from a consideration of the following specification relating to the annexed drawing in which:

FIG. 4 is a side perspective view of the barrel grab assembly mounted on the lift carriage carried by the vehicles mast showing the position of the jaw unit for receiving a barrel;

FIG. 5 is a diagrammatic view illustrating the clamping action of the jaw units of the barrel grab assembly of PEG. 2;

FIG. 6 is a front elevational view of a modified barrel grab assembly;

FIG. 7 is a sectional view taken along the line 77 of FIG. 6; and

FIG. 8 is an enlarged sectional view taken along the line S8 of FIG. 7.

Referring to the drawing there is shown in FIG. 1, a fork lift vehicle 19 in assembly relation with the barrel grab assembly 34 of this invention. The vehicle 10 has a motor (not shown) which drives a pair of front drive wheels 12 and 13. A steering caster Wheel 14 is rotatably mounted on the bottom of the rear end of the vehicle.

The vehicle 163 has a mast 16 which extends in an upward direction from the drive wheels 12 and 13. The mast 16 comprises a pair of outer channel beams 17 and 18 which are pivotally mounted at their lower ends on the vehicle frame. A pair of

inner channel beams

19 and 21 telescope within the beams 17 and 18, respectively, and are connected at their upper ends by a cross member 22. The mast 16 is maintained in an upright position and tilted about the axis of the drive wheels 12 and 13 by a double acting cylinder assembly 23 which is mounted on the vehicle frame. The cylinder assembly 23 has a piston rod 24 connected to the outer beams 17 and 18 by a transverse beam 26.

A carriage 27 extends transversely across the front side of the mast 16 and is guided by the

inner beams

19 and 21 by rollers (not shown) which are positioned in the channels of the

beams

19 and 21. The carriage 27 is connected to the vehicle frame by a pair of lift chains 28 which are secured at one end to the carriage 27. From the carriage 27, the lift chains 28 extend in an upward direction over sprockets 29 which are rotatably mounted on the

inner beams

19 and 21 adjacent the cross member 22 by a transverse shaft 31. The opposite ends of the lift chains 23 are connected to the vehicles frame.

The

inner beams

19 and 21 are moved relative to the outer beams 17 and 18 by an upwardly extended cylinder assembly 32 which is pivotally mounted at its lower end to the vehicle frame. The upper end of the cylinder assembly 32 includes a piston 33 connected to the shaft 31. When hydraulic fluid under pressure is supplied to the bottom of the cylinder assembly 32, the piston 33 is moved in an upward direction carrying the

inner beams

19 and 21 and the carriage 27 in an upward direction. The carriage 27 moves in a downward direction when the hydraulic fluid in the cylinder assembly 32 is permitted to flow back into a reservoir (not shown).

The barrel grab assembly 34 is mounted on the carriage 27 and as shown in FIG. 2, comprises a base plate 36 which is positioned transversely across the carriage 27. The top edge of the back surface of the plate 36 has rearwardly extended spaced projections 37 which maintain the plate 36 in transverse alignment with the carriage 27. A shaft 38 projects through the sides of the carriage 27 and the projections 37 to pivotally mount the plate 36 on the carriage.

A pair of forwardly extended

jaw units

39 and 41, respectively, are pivotally mounted on the plate 36 for movement about reversely inclined axes. The jaw unit 39 has a sleeve 42 which extends parallel to the plane of the plate 36. An arm 43 is secured to the sleeve 42 and extends in a forward direction away from the plate 36 above the center line of the sleeve 42. The arm 43 has secured thereto an arcuate-shaped hand or jaw member 44 having an inside wall with a concave curvature substantially that of the curvature of the side wall of a barrel 11 to be gripped. The forward end of the jaw member 44 terminates in a lip 45 which has an upwardly and forwardly directed bottom edge 46. The lip 45 extends in an outward direction so as to guide the jaw member 44 around the barrel.

The sleeve 42 is positioned about a rod 47 which pro jects inwardly and upwardly from the side of the plate 36. The opposite ends of the rod 47 are rotatably mounted in

tabs

48 and 49 which are secured to the forward surface of the plate 36. Each tab has a bore for receiving an end of the rod 47. Retaining means 51, such as snap rings and cotter keys, are fastened to the ends of the rod 47 and function to hold the rod 47 against axial movement. 1

The arm 43 and jaw member 44 are held in a horizontal position, lateral from the forward surface of the plate 36, by a triangular-shaped leg member 52 secured to the sleeve 42 and the arm 43 and extended in a downward direction. As shown in FIG. 3, the rear end of the leg member 52 is secured to the sleeve 42 and engages the plate 36.

The rod 47 has an axial length which is greater than 3 the axial length of the sleeve 42 so that the sleeve 42 can be axially moved relative to the rod 47 roviding for a change in position of the jaw member 44 transversely of the truck as shown in broken lines in FIG. The leg ?member 52 is in alignment with a pair of axially spaced

blocks

53 and 54 which are secured to the plate 36 ad- ,jacent the rod 47. The

blocks

53 and 54 function as stops for the arm 43. The leg member 52 coacts with either the block 53 or the block 54 to position the arm '43 axially of the rod 47. An additional transverse adjustment of the arm 43 is obtained by rnoying the sleeve 42 into engagement with the tab 43. This position defines the maximum transverse or outward location of the jaw member 44. j

The jaw unit 41 has a construction which is similar to the jaw unit 39. The jaw unit 41 has a sleeve 56 and a forwardly extended arm 57 secured to the sleeve. An arcuate-shaped jaw member 58 is secured to the forward end of the arm '7 above the axis of the sleeve 56. The jaw member 58 has an inside wall having a concave contour which substantially coincides with the curvature of the barrel. The forward end of the jaw member terminutes in an outwardly directed lip 59 which has a bottom edge 6%) projected upwardly and forwardly to guide the barrel into the jaw member 58. A rod 61, positioned adjacent the plate 36 in a plane which is reversely inclined from the rod 47, is fastened to the plate 36 by spaced

tabs

62 and 63 secured to the plate 36. The

tabs

62 and 63 have axially aligned openings for receiving the ends of the rod 61. Retaining means 64, such as cotter keys or snap rings, extend through the ends of the rod 61 and hold the rod in engagement with the

tabs

62 and 63.

As shown in FIG. 3, a triangular-shaped leg member 66 is secured to the outside edge of the arm 57. The leg member 66 extends in a downward direction with the outer end thereof in engagement with the mid-section of the jaw member 58 and the inner end secured to the sleeve 56 and extended into engagement with the plate 36. The leg member 66 functions to hold the arm 57 and jaw member 58 in a forward direction away from the outer surface of the plate 36.

As shown in FIG. 3, the rod 61 extends between the

tabs

62 and 63 and has an axial length which is greater than the axial length of the sleeve 56. The transverse position of the jaw member 58 may be varied by moving the sleeve 56 axially of the rod 61. The adjusted position of the sleeve 56 relative to the rod 61 is established by the tab 63 which is engageable with the end of the sleeve 56 and a pair of axially spaced

blocks

67 and 63 which are secured to the plate 36 below the rod 61. The

blocks

67 and 68 are transversely spaced and define stops which coact with the inner end of the leg member 66 to maintain the axial position of the sleeve 56 on the rod 61.

In use, the

jaw units

39 and 41 are adjusted along the

rods

47 and 61 until the space between the

jaw members

44 and 58 is substantially equal to the diameter of a barrel. Each jaw unit is adjusted by pivotally moving the arm in an upward direction to move the leg member out of engagement with the plate 36. With the arm member held in an upward direction the sleeve is movable relative to its associated rod to an adjusted position. This adjusted position is retained 011 return of the arm and its associated jaw member back to its forward extended position by the coasting engagement of the leg member with one of the blocks. This coaction between the leg memher and the blocks maintains the jaw unit in its adjusted position.

As shown in FIG. 4, in order to position the

jaw units

39 and 41 about the barrel 11 the carriage 2.7 is lowered to the bottom end of the mast 16 to locate the arm and jaw members adjacent the mid-section of the barrel 11. The vehicle is then moved in a forward direction until the barrel is received between the facing concave contoured side walls of the

jaw members

44 and 58. During the forward movement of the vehicle the upwardly and forward- 1y projected bottom lip edges 46 and 60 of the

jaw members

44 and 58, respectively, ride up on the opposite sides of the barrel 11 as shown in full lines in FIG. 5. When the barrel 11 is between the facing contour sections of the

jaw members

44 and 58 they move downwardly and inwardly as shown by the broken lines in FIG. 5, to grip or embrace opposite portions of the midsection of the bar 1'31 With the application of fluid pressure to the cylinder as einbly 32 the carriage 27 and the barrel grab assembly 34 are moved in an upward direction. The arms and associated jaw members rotate in a downward direction until the

leg members

52 and 66 engage the plate 36. Additional upward movement of the barrel grab assembly results in the lifting of the barrel in an upward direction. When the

jaw units

39 and 41 rotate in a downward direction about the

rods

47 and 61, respectively, the

jaw members

44 and 58 move downwardly and toward each other to effect a clamping or hugging action on the midsection of the barrel 11 between the beads thereof. See FIG. 5. v

After the barrel 11 has been transported by the vehicle it) to its new location the carriage27 is lowered until the barrel 1?. rests on the ground. The jaw members 4% and 58 may be removed from the barrel 11 by continuing the lowering of the carriage 27 after the barrel is in engagement with the ground so as to pivot the

arms

43 and 57 in an upward direction about the

rods

47 and 61. Pivotal movement of the arms 43 and S7 in an upward direction moves the jaw members 44- and 58 out of engagement with the opposite sides of the barrel 11 as the plane or" movement of the

jaw members

44 and 53 is defined by the reversely inclined axes of the

rods

47 and 61. As a result of this reversed inclination of the axes for the

rods

47 and 61, the free ends of the jaw members move away from each other, in relatively diverged paths, on upward movement of the jaw members, and toward each other in relatively converging paths on downward movement of the jaw members. After the

jaw members

44 and 58 have been moved out of clamping engagement with the opposite sides of the barrel 11 the vehicle 16 is driven in a reverse direction moving the

jaw units

39 and 41 from the barrel 11.

The modified barrel grab assembly shown in FIGS. 6 and 7 is indicated generally with the number 69 and is operable to concurrently grip a pair of barrels or drums 71 and 72. The assembly 69 is similar in construction to the barrel grab assembly 34 and is mounted on a vertically movable carriage 73 of a fork lift vehicle.

The assembly 69 has a fiat base plate 74 positioned adjacent the forward side of the carriage 73 and extended transversely of the vehicle. As shown in FIG. 7, the plate 74 is maintained in transverse alignment with the carriage 73 by a pair of projections '76 and 77 secured to the top of the back side of the plate 74. The

projections

76 and 77 abut the inside facing surfaces of the sides of the carriage to limit the movement of the plate 74 transversely of the carriage. A transverse shaft 75 extends through the sides of the carriage and

projections

76 and 77 to pivotally connect the plate 74 to the carriage.

As shown in FIG. 7, a pair of

movable jaw units

79 and 81 project in a forward direction from the opposite end sections of the plate 74. The

jaw units

79 and 81 pivot about reversely inclined axes which lie in a transverse plane which is substantially parallel to the plate 7ft. Each jaw unit moves in an upward and outward direction away from the sides of an associated barrel.

A fixed arm 82 is secured to the mid-section of the plate '74 and lies substantially midway between the

jaw units

79 and 81. The arm 82 comprises an u right plate 83 secured to the plate 74 and projected in a forward direction. The plate 83 terminates in a pointed forwzud end 84. A pair of

horizontal gusset plates

86 and 87 are secured to the plate 74 and to opposite sides of the upright plate 83. The top surface of each

plate

86 and 87 is coextensive with the top wall of the upright plate 83. The

gusset plates

86 and 87 have rearwardly and outwardly directed

forward walls

88 and 89, respectively, which are engageable with side walls of the barrels 71 and 72.

The jaw unit 79 has a sleeve 91 positioned in the plane of the reversely inclined axes. Secured to the sleeves 91 and extended in a forward direction away from the plate 74 is an arm 92. An arcuate-shaped jaw member 93 is secured to the arm 92 and positioned above the axis of the sleeve 91. As shown in FIG. 6, the forward end of the jaw member 93 terminates in an outwardly directed lip 94 which has an upwardly and forwardly directed bottom edge 96. The lip 94 functions as a cam follower to guide the jaw member around the barrel. The inside wall of the jaw member 93 has a concave curvature which substantially conforms to the curvature of the side walls of a large barrel.

As shown in FIG. 8, sleeve 91 is positioned about a rod 97 which extends inwardly and upwardly from the side of the plate 74. The opposite ends of the rod 97 are rotatably mounted in forwardly projected

tabs

98 and 99 which are secured to the plate 74. Retaining means 101, such as snap rings and cotter keys, are fastened to the ends of the rod 97 and function to hold the rod in the

tabs

98 and 99.

The arm 92 and jaw member 93 are held in a substantially horizontal position by a triangular-shaped leg member 192 which extends downwardly and inwardly as shown in FIG. 8. i The leg member m2 is secured to sleeve 91 and the arm 92 and is engageable with the forward surface of the plate 74 to limit the downward angular movement of the arm and sleeve about the rod 97.

As shown in FIG. 8, the rod 97 has a length which is substantially greater than the length of the sleeve 91 thereby permitting the sleeve 91 to be moved axially relative to the rod 97 to change the position of the jaw member 93 transversely of the vehicle for the purpose of accommodating barrels of varying diameters. The adjusted position of the jaw unit 79 is maintained by a pair of spaced blocks 193 and 104 which are secured to the plate 74 below the rod 97. The blocks 193 and 104 determine the stop positions of the jaw 79. The leg member 102 meets with either the block 103 or the block 164- to fix the position of the sleeve 91 and arm 92 relative to the rod 97. An additional transverse adjustment of the jaw member 93 is obtained when the sleeve 91 abuts the tab 98. This position defines the maximum outward location of the hand member 93.

The jaw unit 81 is similar in construction to jaw unit 79 and comprises a sleeve 1%, an arm 16'] secured to the sleeve and extended in a forward direction, and a curved jaw member 108 secured to the arm 1M and positioned above the axis of the sleeve 1%. The inside wall or" the jaw member 168 has a concave contour which substantially coincides with the curved shape of the side walls of the barrel 71. The jaw member 188 terminates in a forward lip 169 which projects in an outward direction. As shown in FIG. 6, the bottom edge 111 of the lip 169 extends upwardly and forwardly and forms a cam follower surface which rides on the curved side wall of the barrel 71 during the positioning of the barrel grab assembly about the barrels 71 and 72.

A rod 1.12 extends through the sleeve 1% and is rotatably mounted in tabs 113 and 114 which are secured to the plate 74-. The rod 112 projects inwardly and upwardy from the side of the plate 74. Retaining means us, such 'as cotter keys or snap rings, are connected to the opposite ends of the rod 112 to retain the rod in the tabs 113 and 114.

The sleeve 1% has an axial length which is shorter than the length of the rod 112 thereby enabling the jaw unit 81 to be moved in a direction transversely of the vehicle as shown by the broken line position in FIG. 7.

The transverse position of the jaw unit 81 is maintained by a downwardly and inwardly extended leg member 117 which coacts with a pair of spaced

blocks

118 and 119 secured to the plate 74 below the rod 112. The maximum adjusted outward position of the jaw member 168 is obtained by moving the sleeve 1496 in engagement with the tab 114 as shown in solid lines in FIG. 7.

in use, the

jaw units

79 and 81 are moved along their

respective rods

97 and 112 until the transverse space between each jaw member and the fixed arm 82 is substantially equal to the diameters of the barrels 71 and 2 which are to be transported.

Each jaw unit is adjusted by rotating the arm in an upward direction thereby moving the leg member away from the plate 74. When the leg member is moved from a coacting relationship with respect to the blocks secured to the plate 74 the sleeve can be moved axially relative to the rod. Rotation of the arm and its associated jaw member back to its forward extended position places the leg member into a coacting relationship with one of the blocks. When the arm member is in its maximum transverse or outward position the end of the sleeve engages the outside tab.

When the

jaw units

79 and 81 and the fixed arm 82 are to be positioned about a pair of barrels 71 and 72, the carriage 73 is lowered until the

hand members

93 and 103 are adjacent the mid-section of the barrels. The vehicle is moved in a forward direction positioning the lips 94 and 199 in engagement with opposite portions of the barrels 71 and '72. The upwardly directed bottom edges 96 and 111 of the respective lips ride up on the opposite sides of the barrels rotating the

jaw units

79 and 81 in an upward direction. The reverse inclined position of the

rods

97 and 112 effect an outward movement of the jaw members 93 and 168 when the jaw units are rotated in an upward direction thereby permitting the

jaw units

79 and 81 to be positioned about the barrels.

In the loaded position the barrels 71 and 72 are in engagement with the inside walls of the jaw members 93 and 168, the opposite sides of the'upright plate 83 and the

forward walls

88 and 89 of the

gusset plates

36 and 37. When the carriage 73 is moved in an upward direction thejaw units rotate in a downward direction until their respective leg members engage the plate 74. The inclined position of the

rods

97 and 112 define the plane of movement of the

hand members

93 and 108 which on downward movement is toward each'other to perfect a concurrent clamping action on the sides of the barrels 71 and 72. The jaw members hug the section of the barrels between the fixed arm 82 and the

jaw members

93 and 108.

After the barrels '71 and 72 have been transported to their new location the carriage 73 is lowered until the barrels rest upon the ground and are released by the jaw units. The barrel grab assembly is removed from the barrels by driving the vehicle in a reverse direction. During the reverse movement the

jaw units

79 and 81 slide over the sides of the barrel and pivot in an upward direction to release the clamping action of the

jaw members

93 and 108 on the mid-sections of the barrels.

In summary, the barrel grab assembly is mounted'on the carriage of the fork lift vehicle 10 and has a pair of jaw units which engage opposite sections of the sides of the barrels. Upon upward movement of the carriage the barrel is moved to a raised position. The jaw units are pivoted on reversely inclined axes which diverge downwardly from the center section of the carriage. Pivotal movement of the jaw units in an upward direction effect movement thereof in planes which diagonally intersect the opposite sections of the sides of the barrels. Each jaw unit has a leg member which coacts with a fixed block for adjusting the position of the jaw unit transversely of the truck in order to accommodate barrels of varying sizes.
