Abstract: A quick-coupling link to be utilized in conjunction with an identical link has a slot in one of the longitudinal side portions of the link. A tab extends from the opposite longitudinal side portion to adjacent the slot. The tab spans the width of the slot. When a pair of identical links are joined, the tabs prevent the links from accidentally being uncoupled as the slots cannot be brought into disengaging alignment without bending the flexible tab away from the entry to the slot.

Abstract: A headed mandrel inserted through a rivet sleeve is pulled and snapped off its head by a riveter to deform the rivet sleeve for setting the rivet when a movable handlebar is pivotally moved relative to a fixed handlebar by hand. An operating bar pivotally supported by the main body of the riveter has one end pivoted to a chuck for gripping the mandrel and the other end serving as an engaging portion. A pusher is pivoted to the movable handlebar and has grooved portions engageable with the engaging portion. A bearing member pivoted to the main body is formed with bearing grooves positioned alongside the grooved portions in corresponding relation thereto and engageable with the engaging portion. When the movable handlebar is repeatedly turned, the pusher pushes the engaging portion in engagement with one grooved portion after another to engage the engaging portion correspondingly in one bearing groove after another and move the chuck by the resulting movement of the operating bar for setting the rivet.

Abstract: A crimping tool includes a pair of arm members and a driving mechanism such as a pair of handles for moving the arm members.

Abstract: A manual riveting tool for the setting of blind rivets comprises a flat head whose housing carries the chuck which engages the mandrel and at least one pivotable member which is coupled with the chuck by a transmission in the head to draw the mandrel through the rivet and tear away. According to the invention, this member is provided with a lever to which an actuating arm can be removably connected by a plug-and-socket arrangement and the member further, at one of its ends at a side of the housing can be engaged by a standard socket wrench via another plug-and-socket connection. The housing may be formed with part of still a further plug-and-socket connection, e.g. for engagement by a handle. The plug-and-socket connections can be standard socket-wrench elements.

Abstract: A forging machine transfer is disclosed which is operable in response to transfer movement to turn a gripped workpiece about an axis perpendicular to a plane containing the axis of an elongated workpiece. A single pivoted gripper grips the workpiece against a flat, nonrotating platform and causes the workpiece to slide along such platform as the workpiece is transferred to a subsequent work station. The pivot axis is eccentrically located so that the workpiece is moved toward the die face during transfer to be properly positioned for subsequent working at the delivery position. A pivoted drive linkage provided to produce the rotation is located above the work station to reduce the likelihood of bearing damage resulting from scale or the like. The angle through which the workpiece is rotated can be selected within a range substantially greater than 90 degrees and substantially less than 90 degrees.

Abstract: A method is provided for shaping an object consisting of a material which is both elastic and capable of permanent deformation, by deforming said object with a blast of solid particles.

Abstract: An apparatus and method for the in situ field conversion of the components of pivotal couplings, particularly as utilized for connecting hydraulic load sensing devices into deadline cable anchoring apparatus, and which have become stuck and inoperative due to corrosion, into a coupling having a substantially non-corrosive pivot pin and associated bearing surfaces.

Abstract: A tube shaping machine includes a plurality of dies each having a substantially continuous, unbroken working surface. These dies are mounted with the working surfaces positioned one adjacent to the next so as to form a tube-receiving aperture therethrough, which aperture defines in cross-section regular polygon. The dies are substantially identical in configuration, this configuration being such that reciprocating each of the dies along a predetermined straight line throughout a range of positions between a fully open position and a fully closed position of the tube-receiving aperture maintains a similar regular polygonal cross-sectional shape of said tube-receiving through aperture throughout said range of positions.

Abstract: A nut installation apparatus or head for installing self-attaching nuts, such as pierce nuts, in a panel, without the requirement of a large forming die press assembly. The apparatus includes a nut anchor, which holds the first or end nut stationary, a relatively movable die member, opposite the nut anchor, which supports the panel and a resiliently supported nut guide having a passage receiving nuts in bulk or strip form. The panel is biased into contact with the end nut and nut guide, by the movable die, to install the nut in a panel. Where the nuts are in strip form, the apparatus first severs the end nut from the strip and then attaches the nut in the panel, in a separate step. A unique sensor is provided to assure proper installation.

Abstract: The invention relates to a method and a device for bending sheet-metal sections. It is previously known to bend sectional sheets, but the known art involves certain problems to bring about a non-angular bend with a small radius and without damaging the sheet. According to the invention it is proposed for eliminating said problems, that in connection with the impressing of the sheet portions located closest to the bending axis the lateral portions (1c; 32c; 50c) of the sheet are subjected to an outwardly directed force (17; 39; 56) or prestressing in a plane through the impressions (34; 59), in order to form an outward bulging (40; 58) in the lateral portions (1c; 32c; 50c) and on the same side of the sheet as the impressions (34, 59).

Abstract: A method is described of prestressing structural members wherein there are a pair of longitudinal elements, a plurality of strut elements and a plurality of diagonal members. A plurality of joint connector means enable the strut elements and diagonal members to be interconnected rigidly together as an inner latticework, and the latter to the longitudinal elements. The inner latticework is initially left freely moveable relative to the longitudinal elements, and a prestressing tensile load applied only to said latticework. While the prestressing load is being applied, the longitudinal elements are rigidly secured to the inner latticework. When the prestressing load is then removed, the diagonal members remain in tension, the strut elements remain in compression and the longitudinal elements acquire a compressive load. The prestressing load should not generate any moments or rotational forces at the junctions of diagonals with the strut and longitudinal elements that have not been accounted for.

Abstract: An improved radial or parallel press includes a hydraulic control valve and cylinder for each jaw or foot of the press and a corresponding plurality of valve control cams which move together to actuate the control valves in synchronism.
