Total Claims: 11
Claim 1
Independent Claim
169 words
An apparatus for slinging and rotating sheet rolls, the apparatus substantially comprising two parts movable respectively to each other a first fixed part of which, adapted to be hung to the hook of a lifting means, supports and guides the second movable part of the apparatus, this latter part comprising a boxed L-beam having its legs interconnected by a circle arc section and supporting a pair of opposite jaws for roll slinging, one of said jaws being relatively substantially fixed, while the other is movable along guides formed longitudinally of one leg of said L-beam, the apparatus further comprising first planar support means extending along one leg of the second part and second planar support means extending along a second leg of the second part for Supporting the second part on the first part and curved support means joining the planar support for rotating in either direction on a vertical plane said second part relative to said first part, and means for moving said movable jaw in either direction.
Claim 2
Independent Claim
169 words
An apparatus for slinging and rotating sheet rolls, the apparatus substantially comprising two parts movable respectively to each other a first fixed part of which, adapted to be hung to the hook of a lifting means, supports and guides the second movable part of the apparatus, this latter part comprising a boxed L-beam having its legs interconnected by a circle arc section and supporting a pair of opposite jaws for roll slinging, one of said jaws being relatively substantially fixed, while the other is movable along guides formed longitudinally of one leg of said L-beam, the apparatus further comprising first planar support means extending along one leg of the second part and second planar support means extending along a second leg of the second part for Supporting the second part on the first part and curved support means joining the planar support for rotating in either direction on a vertical plane said second part relative to said first part, and means for moving said movable jaw in either direction.
Claim 3
Dependent Claim
37 words
An apparatus according to claim 1, wherein said first part of the apparatus is provided with rolling pins, wherein the support means comprise guiding surfaces of said second part of the apparatus bearing on the rolling pins.
Claim 4
Dependent Claim
97 words
An apparatus according to claim 2, wherein said planar and curved support means for supporting and for rotating the second part of the apparatus in either direction further comprise first and second straight racks joined by a curved rack, and further comprising at one end of each of said rolling pins a toothed pinion, this pinion meshing with a corresponding rack carried by the second part of the apparatus, the other end of each rolling pin being connected through gears to a common operating shaft driven by a motor located on the first part of the apparatus.
Claim 5
Dependent Claim
21 words
An apparatus according to claim 3, wherein said common operating shaft is connected to said motor by a r.p.m. reducing device.
Claim 6
Dependent Claim
39 words
An apparatus according to claim 3, wherein the second part of the apparatus or boxed L-beam is of a substantially T-shaped cross-section, wherein the guiding surfaces and said racks are located under the lower surfaces of said L-beam legs.
Claim 7
Dependent Claim
54 words
An apparatus according to claim 1, wherein said means for moving said movable jaw in either direction comprise a pair of guides formed longitudinally of one of said L-beam legs, a scroll sliding in said guides and carrying at the bottom said movable jaw, said scroll engaging a screw driven by a suitable motor.
Claim 8
Dependent Claim
47 words
An apparatus according to claim 1, wherein said second jaw is carried by the other leg of said L-beam relative to the leg carrying the movable jaw, and at least one of said two jaws can independently move to the other for providing a self-pressing gripping action.
Claim 9
Dependent Claim
19 words
An apparatus according to claim 1, wherein the load gravity center is substantially always on the vertical lifting axis.
Claim 10
Independent Claim
190 words
An apparatus for slinging and rotating sheet rolls, the apparatus substantially comprising two parts movable to each other a first fixed part of which, adapted to be hung to the hook of a lifting means, supports and guides the second movable part of the apparatus, this latter part comprising a boxed L-beam having its legs interconnected by a circle arc section and supporting a pair of opposite jaws for roll slinging, one of said jaws being substantially fixed, while the other is movable along guides formed longitudinally of one leg of said L-beam, the apparatus further comprising means for rotating in either direction on a vertical plane said second part relative to said first part, and means for moving said movable jaw in either direction, wherein the respective jaws are carried on respective legs of the L-beam, and wherein the jaw which is relatively fixed with respect to the movable jaw is connected to its leg by pairs of connecting rods pivoted at first ends thereof to said L-beam leg for allowing said jaw to move through a short distance towards the movable jaw to provide for self pressing action.
Claim 11
Independent Claim
190 words
An apparatus for slinging and rotating sheet rolls, the apparatus substantially comprising two parts movable to each other a first fixed part of which, adapted to be hung to the hook of a lifting means, supports and guides the second movable part of the apparatus, this latter part comprising a boxed L-beam having its legs interconnected by a circle arc section and supporting a pair of opposite jaws for roll slinging, one of said jaws being substantially fixed, while the other is movable along guides formed longitudinally of one leg of said L-beam, the apparatus further comprising means for rotating in either direction on a vertical plane said second part relative to said first part, and means for moving said movable jaw in either direction, wherein the respective jaws are carried on respective legs of the L-beam, and wherein the jaw which is relatively fixed with respect to the movable jaw is connected to its leg by pairs of connecting rods pivoted at first ends thereof to said L-beam leg for allowing said jaw to move through a short distance towards the movable jaw to provide for self pressing action.
