Abstract: A sliding block coupling has a coupling head which comprises devices for arranging an ingoing, driving, and an outgoing, driven, torque-transferring member which rotate together with the coupling head, and sliding blocks arranged in a cylindrical recess situated perpendicular to the rotation axis of the coupling head so as to, in cooperation with the coupling head, transfer torque from one of said members to the other. The devices for arranging one of the two torque-transferring members comprises structure arranged in the cylindrical recess in the coupling head, this structure transferring torque between the member in question and the sliding blocks, and being extended in the longitudinal direction of the recess and, at least in the proximity of both of its ends and on opposite sides of the same, being provided with projections or recesses on which or in which the sliding blocks are arranged between that structure and the wall in the cylindrical recess.

Abstract: A drive device for oscillating a spring-suspended device, such as a sieve or transport device, into an elliptical translational movement with a minimum of rotation. Two unequal and eccentrically arranged oscillation masses, rotatably fixed to the device, are rotationally driven each by a motor independent of the other. If the axes of rotation for the two masses are arranged in a certain geometry relative to the center of mass, the device will oscillate with a substantially pure translational, elliptical movement free of tipping movement.

Abstract: A rotatable roller arrangement is described, especially for rapidly-rotating rollers intended for abutment pressure such as roller guide rollers in rolling mills, which is rotatably journalled on a stationary shaft by means of at least two ball bearings situated symmetrically inside the roller on both sides of a shoulder arranged inside said roller. The shoulder, defining the axial positions of the bearings in the roller, has the shape of a ring which is held in a cylindrical bore for the same and the bearings pass through the roller, said bore surrounding the shaft. The outer and inner rings of the bearings are movable in the cylindrical bore of the roller and on the shaft, respectively, and are axially urged away from the shoulder-forming ring inside the roller.

Abstract: The present invention relates to a device for controlled cooling of wire, especially steel wire. According to the invention the device comprises, in combination, a movable conveyor to which wire is continuously supplied in open ring windings for movement of the same in mutually displaced positions, means surrounding the conveyor for control of the temperature ratios of the wire, and a collection device for the cooled ring windings, said conveyor essentially having the shape of an inclined plane which rotates about its center.

Abstract: Apparatus for twisting and guiding metal stock into roll grooves, comprises a guide mounted in front of such a groove. The guide has a through path from which the stock emerges from the guide and passes to the groove, and a feed path disposed to one side of the through path. The feed path is defined by a funnel-shaped member having an opening therethrough of about the same size and shape as the stock to be fed, and which is mounted for swinging movement between two positions, in one of which it is out of line with the through path and in the other of which it is in line with the through path. The stock is fed through the swinging member in the out-of-line position and contacts a cam surface which moves the stock and hence the swinging member, into line with the through path, thereby twisting the stock about 90.degree.. After the stock is passed, the swinging member returns by gravity to its out-of-line position.

Abstract: Shears, for cropping wire, and including on the one hand, two rotating cutting bodies overlapping to shear the wire, in the form of cylindrical discs whose planes form a right angle with one another, and on the other hand, means for achieving relative motion of the wire and the shearing discs to perform said cropping, a small portion of the circumferential surface of one of the discs being covered by a small portion of one side surface of the other disc where the two discs overlap for cropping the wire.

Abstract: An improved rod coiling and cooling system includes a coiler which receives hot rod from a rod rolling stand. A guide or repeater section is provided between the rolling stand to effect a bending of the rod to guide it into the coiler. The coiled rod is transferred from the coiler to one of a plurality of coil supports disposed in an indexable tank of water. When a length of rod has been coiled and deposited on one of the coil supports the tank is indexed to move a next adjacent coil support into position to receive a succeeding coiled rod from the coiler. After a coiled rod has cooled in the tank of water, it is transferred to a car, is moved along a first set of rails to a first turntable which is rotated to position the loaded car on a second set of rails leading to a bundling station and a station where the cooled coil is removed from the car. The empty car is moved onto a second turntable which positions the car for movement along the first set of rails back to the loading station.

Abstract: A device for braking rolled stock on a delivery table which has a plurality of spaced rollers for receiving the stock. The device comprises brake plates located between respective rollers and movable to a position to at least in part support the stock thereon. A plurality of brake flaps are movable into position above the brake plates and the brake flaps engage the stock while supported on the brake plates to apply a braking force thereto. The brake flaps are associated with means for adjusting the braking force applied to the stock.

Abstract: An improved table feeder type material handling apparatus includes a support table or tray which is moved through forward and return strokes by a dirve assembly to convey ore or other material disposed on the tray in a forward direction relative to the tray. In accordance with a feature of the present invention, the stroke or distance through which the tray is moved can be varied while maintaining the stroke rate substantially constant. To provide this capability, the drive assembly includes a rotatable input member which is connected with the support tray by a linkage. A connection between the linkage and the input member is offset relative to the axis of rotation of the input member. Therefore, when the input member is rotated about its central axis, one end of the linkage is moved along a circular path.

Abstract: A roller guide for guiding rod or wire stock between a pair of rolls which shape the stock. The roller guide includes a pair of guide rollers which are adapted to engage the opposite surface portions of the stock and are mounted for rotation on a guide housing for rotation about substantially parallel axes. The guide housing is mounted upon a base. Fine adjustment means is included for effecting a fine adjustment of the position of the guide housing relative to the base in order to effect fine adjustment of the guide rollers. The fine adjustment means includes a member which is fixedly supported by the guide housing, a movable adjustment member and resilient means interposed between the member fixed on the guide housing and the movable adjustment member, which yields to enable movement of the guide housing and of both of the rollers to occur in response to forces applied to the rollers.
