Abstract: A vertical rolling mill is disclosed wherein a means for driving the mill rolls is comprised of a rigid vertical spindle having universal joints and couplings at either end which is detachably connected to the mill roll at its lower end and connected to a splined driving member at its upper end. The splined driving member consists of two parts. First, a hollow sleeve is mounted vertically in a drive case on the mill frame. The sleeve is supported within the frame through top and bottom antifriction bearings. It has internal splines at the lower end of its bore and an internal shoulder above the spline end. Second, a vertical shaft with an external spline and collar is inserted into the sleeve. The vertical shaft engages the internal spline of the sleeve and is supported by its collar which rests on the internal shoulder in the sleeve. Thus, the top frame, rather than the mill roll bearing, supports the weight of the spindle, joints and pod coupling.

Abstract: A tool setting device for a machine tool (10) having a numerical control (22) includes a gage unit (24) with a frame (26) adapted to be secured upon a slide (20) of the machine tool. A photodetector, which includes a source (96) and a receiver (98), is mounted upon the frame for generating a first signal indicating the arrival of the tip of a tool (18). A slide (64) mounted upon the frame carries an engagement head (38) adapted to be contacted and displaced by the tool tip. An LVDT (60) is mounted upon the frame in proximity to the engagement head for sensing its axial displacements. A control meter relay (86,88) is operatively connected to the LVDT and generates a second signal after initial displacement of the engagement head and a third signal after displacement of the engagement head to a reference position.

Abstract: A removable element for a tool system is disclosed. The element may be used in a system of slide-on tools and adaptors that eliminates a two-handed operation for changing tool bits. The element comprises at least one prong located at one end at a selected distance and substantially parallel to an axis of rotation of the tool system. The prong is adapted to slidingly fit and rotationally abut with another element of the tool system to transfer rotary motion between the elements, and means are provided for supporting a tool bit on the axis of rotation at the other end of the element from the prong.

Abstract: A drilling machine for drilling a stack of paper, comprises a first movable member moving along directions to press the stack of paper and to remote from the stack of paper and elastically supporting a pressing plate, a second movable member supporting a drilling mechanism and moving along the directions, and a control device for causing first and second driving mechanisms simultaneously to drive the first and second movable members respectively in the direction to release the stack of paper from compression and to separate the drilling mechanism from the stack of paper, whereby the stack of drilled paper is released from compression and the drilling mechanism is separated from the stack of drilled paper.

Abstract: The invention relates to the formation of a substantially circular metallic shield (37) about a cable core (32) by wrapping a metallic tape (64) longitudinally about the core with longitudinal edge portions of the tape being overlapped by a forming key (100) to provide a closed seam (38). As the seam is formed, an underlying longitudinal edge portion (48) of the shield is supported while an overlying longitudinal edge portion (45) at the overlap is directed inwardly toward the cable core to preclude its protrusion into a jacket (39) which is subsequently extruded over the shielded cable core. A relatively thin strip (145) of metal attached to an inner surface of the forming key assures formation of the seam before juxtaposing the longitudinal edge portions and the core, and avoids penetration of a priorly formed inner shield by the longitudinal edge of the outer shield to prevent rotation of the inner shield and undesirable alignment of the shield seams.

Abstract: In the embodiment shown, the chuck comprises a hub rotatably journalled in a jaw carrier, and the latter rotatably journalled in a body. The carrier pivotably mounts a plurality of jaws having camming surfaces, and drive pins upstanding from the hub and the body slidably engage the camming surfaces to move the jaws outwardly, to engage the inner surface of a workpiece, or inwardly, to engage the outer surface of the workpiece. A screw carried in the jaw carrier is movable into the hub, to lock the hub and jaw carrier together, and movable into the body, to lock the body and the jaw carrier together. In the prior circumstance, the drive pins of the body are operative to move the jaws inwardly or outwardly; in the latter circumstance, the pins of the hub are operative to move the jaws as noted above. The jaws have a first plurality of camming surfaces for operative engagement with the drive pins in the body, and a second plurality of camming surfaces for operative engagement with the drive pins in the hub.
