Abstract:
A gripper block for use in grippingly engaging coiled tubing, pipe, rod, cable or like objects having various outside dimensions is provided. The gripper block has a gripping portion which includes a curved and a planar gripping surface. The planar gripping surface preferably includes a pair of opposed sloped planar gripping surfaces to engage coiled tubing, preferably steel coiled tubing of varying diameters. The sloped gripping surfaces preferably provide a V-shaped engagement configuration. The curved gripping surface is adapted to engage coiled tubing, preferably composite coiled tubing having a diameter less than the coiled tubing to be engaged by the sloped gripping surfaces.
Abstract:
An improved gripper unit for use in an injector for handling coil tubing, pipe, rod, cable, or similar elongate objects, this gripper unit being provided with gripping surfaces which contact the coil tubing in V-block fashion and thus will grip such tubing of differing diameters. This gripper unit will enable the injector to support a given load while applying less squeeze. In the case of handling coil tubing or pipe, the stresses induced by these improved gripper blocks are very considerably reduced as compared with conventional gripper blocks.
Abstract:
A new type of gripping shoe for traction devices of the caterpillar type, comprising a deformable element of composite structure. The deformable element comprises a body member which is mechanically resistant, deformable and of low elasticity. This body member is provided with a large internal recess housing a sole member of a highly deformable, elastic and substantially incompressible material.
Abstract:
A workpiece feed channel interposed between a metal peeling machine and straightener for elongated, rotating or non-rotating, metal workpieces. The channel includes a plurality of opposed pairs of driven profiled elements having workpiece receiving openings therebetween of a cross-sectional size approximately 1.5 to 10 times larger than the cross-sectional size of the workpieces carried therein. The workpieces are carried by and fed forwardly by the gravitational frictional engagement with the profiled elements. In one embodiment, the upper profile elements are raised to permit the release of the workpiece down inclined surfaces, rather than for the workpiece to continue on to the straightening machine.
Abstract:
Articles such as axially elongated carpet rolls are transferred from the delivery end of an input conveyor to a sorter conveyor for delivery to preselected destinations by a pair of rotor assemblies that are rotationally indexed between predetermined positions in sequential overlapping relation to each other. Rotation of the rotor assemblies are synchronized with operational conditions of the input and sorter conveyors.
Abstract:
A structure for supporting drums such as beer kegs. The drum is adapted to be supported with its axis extending horizontally, and the drum has between its ends a rolling ring. The structure includes a pair of elongated parallel frame members which extend perpendicularly to the drum axis and a pair of elongated parallel drum-engaging members which extend parallel to the drum axis and which extend perpendicularly with respect to the frame members and are fixed thereto. The frame members are spaced at a substantial distance from each other and the drum-engaging members are also spaced at a substantial distance from each other. The pair of drum-engaging members are respectively formed at their inner edges with a pair of aligned notches for receiving the rolling ring of the drum, so that with this construction the pair of drum-engaging members will oppose rolling movement of the drum perpendicularly across the drum-engaging members while the notches will oppose axial movement of the drum in a direction parallel to the drum-engaging members. This structure may form either part of a pallet or part of a spacer to be situated between a pair of drums which are located one above the other.
Abstract:
Apparatus of the invention is especially suitable for utilization in conjunction with the conveyor table of a reversing rolling mill used for rolling lengths of T-bars, angle bars and other similar elongated shapes of metal. The apparatus is normally disposed between a pair of adjacent rollers of the conveyor table and consists of a fluid pressure cylinder rigidly mounted in substantially upright position adjacent one side of the roller table and a counterweighted substantially U-shape frame pivoted on the bottom of the roller table opposite the cylinder for movement between one position toward the cylinder between the pair of adjacent rollers and another position remote from the rollers in the direction away from the cylinder. A link member, which may be in the shape of a chain, normally extends from the piston rod of the fluid pressure cylinder to the upper portion of the frame member below the upper surface of the rollers of the roller table. A pair of fingers projects upwardly from the frame and is adapted to engage an elongated article on the table and cause it to be turned about the fingers when the cylinder is actuated, the chain is raised, and the frame is pivoted toward the cylinder.
Abstract:
A DEVICE FOR TRANSFERRING BARS FROM THE COOLING BED OF A HOT ROLLING MILL TO A TRANSPORT ROLER PATH INCLUDES AN ARTICULATED QUADRILATERAL OR FOUR-BAR LINKAGE ARRANGEMENT. THE FOUR-BAR ARRANGEMENT IS ACTUATED BY AN ECCENTRIC TO RECIPROCATE A BAR CARRIER THROUGH FORWARD
AND RETURN STROKES. A PLURALITY OF BARS ARE TRANSFERRED FROM THE COOLING BED TO THE TRANSPORT PATH ON EACH FORARD STROKE OF THE CARRIER.
