Abstract: A hog-ring type clip-applying device having an upper jaw and a lower jaw with a clip receipt area defined therebetween to receive and clench a hog ring clip. The lower jaw is attached to a rear handle, and the upper jaw is attached to a diagonally disposed lever bar which is pivotally attached near its top to the lower jaw. The lever bar is pivotally attached at its bottom to a front handle member which has a guide opening disposed at the top thereof to receive therethrough the upper and lower jaws. A spring member urges the front handle member apart from the rear handle. A clip slide directs clips forward into the clip receipt area between the upper and lower jaws such that when the front and rear handles are moved together, the jaws grasp a clip from the forwardmost end of the clip slide and move forward through the guide opening in the top of the front handle to a position such that when the front and rear handles are further moved together, they clench the clip.
Abstract: A hand-held pneumatic device, such as a C ring clamping device, comprises a main body, a grip joined to a lower portion of the main body, a pneumatic cylinder contained in the main body, and a directional control valve contained in the main body. A first air discharge passage formed in the grip is connected to a first discharge port of the directional control valve and has an open end in a lower end portion of the grip. A second air discharge passage formed in the main body is connected to a second discharge port of the directional control valve and has an open end opening in a back portion of the main body. The open end of the second air discharge passage is connected to an inner portion of the first air discharge passage, near the first discharge port of the directional control valve, so that air is discharged through the open end of the first air discharge passage.
Abstract: A machine in which butterfly clips are prebent and then punched out of steel strip and simultaneously finally bent, such that they fasten together a spring and the frame of a spring core. Thus, both the punching out of the clip and the final bending process, i.e. the connecting process between the frame and spring parts, are carried out in a single tool. The machine therefore operates particularly cost-effectively, because, in comparison with the prior art, the separately punched butterfly clips do not have to be inserted into a separate bending machine.
Abstract: Method and apparatus for securing a fastener around two members, the jaws of which are initially retracted to allow loading of a fastener from a magazine, cassette, clip, or cartridge into the jaws. A piston is then moved into engagement with the jaws, which capture the fastener, shearing the fastener from the magazine, to move the fastener into position over the two members around which the fastener is to be secured. A ram is positioned against the fastener to hold the fastener against the members and to facilitate bending of the fastener at desired points to conform the fastener to the shape of the members. The jaws then close around the members, bending the fastener, as the piston continues downward movement. The piston is then moved in the opposite direction to first allow the jaws to return to the open position and then to retract the jaws to allow loading of a second fastener.
Abstract: A device for automatically securing a borderwire on a mattress innerspring comprising a plurality of coils is disclosed. The device comprises a tool for sequentially joining segments of the borderwire to perimeter ones of the coils located along a perimeter of the innerspring, apparatus for advancing the mattress innerspring and borderwire toward the tool, a conductive element for sequentially contacting the perimeter ones of the coils, a sensor for detecting contact of the conductive element with the perimeter ones of the coils, and a control responsive to the sensor for actuating the tool.
Abstract: Apparatus for automatically securing borderwires on mattress innersprings, comprising support members for receiving borderwires and a mattress innerspring in stacked, properly oriented relation to one another. A drive mechanism is provided for automatically sequentially advancing the borderwires and the mattress innerspring along the support members to a clip wrapping station where a plurality of clips are simultaneously wrapped on the borderwires and the coils of the mattress innerspring. Control elements are provided for sensing when clips are to be wrapped, and when a predetermined number of clips have been wrapped on each side and each end of borderwires and the mattress innerspring.
Abstract: An active clincher 201 has a housing 202 forming a support surface 203 for an article, such as a set of sheets, to be stapled. One or a pair of clincher ears 204 is positively driven by an actuator 223 for bending over the staple leg(s) to form clinches. The clincher ears 204 are pivotally mounted on the housing 202 and rotatable by the actuator 223 so as to engage and bend the staple legs. The or each clincher ear 204 is mounted, suitably by having a slotted pivot hole 212, so that it also moves normally to the support surface during and/or following the end part of the rotational movement of the ear.
Abstract: Equipment to visually identify insertion points to an operator of a pre-programmed, semi-automatic electronic assembly station. This equipment includes a pair of illuminators disposed at opposite ends of a cut-clinch mechanism and arranged to shine on the underside of the circuit board. The illuminators are carried by the cut-clinch mechanism and are free to move transversely and rotate axially, as the mechanism rotates and moves during the assembly steps.
Abstract: An electronic component lead cutting and outwardly clinching mechanism for cutting the component leads that extend from the underside of a printed circuit board and for outwardly clinching the portions of the leads remaining after the cutting to the underside of the printed circuit board. The severed scrap portions of the leads fall into a scrap discharge chute to be carried away from the cutting and clinching mechanism. A lead detector is incorporated into the mechanism to detect the presence or absence of the leads during the shearing action.

Abstract: A clinch tool and method for clamping a grid frame to a coil in which a clinch component is fed automatically into a space formed by the tool between the grid frame and coil with the clinch component saddled in position on the grid frame to be bent to retain the coil in a locked condition to the grid frame.
Abstract: The mechanism cuts component lead portions projecting from a support such as a circuit board though the leads may be spaced apart at different distances, and then clinches them against the board. Additionally, the mechanism is movable heightwise relative to the support for clearance purposes and adapted to be shifted both in X-Y directions and with selected radial orientation between preset angles. The clinching is done in opposite directions and normal to a line interconnecting the points from which the leads protrude thereby stabilizing the position of a component body.
Abstract: Electrical component leads, extending through apertures of a printed circuit board, are cut and clinched by reciprocating cutter blocks moved transverse to the axis of the leads. All the leads are cut with selected ones being bent to a greater extent than the remainder of the leads.
Abstract: A machine for binding packets of perforated sheets to book form with wire binding elements each formed from a length of metal wire bent to form a series of curved hairpin-shaped prongs on which the sheets are impaled and which are brought to ring shape by bringing their closed ends or "points" into the vicinity of their open ends or "roots" wherein is provided a reception station for the binding elements which are in the open condition, a binding station at which the perforated sheets are impaled upon the prongs of the elements and the latter are closed, means for conveying the open elements from one station to the other, and a rectifying tool in the form of a wedge-shaped bar arranged for reciprocating into and out from the slot in a binding element characterised in that the wedge head of the bar has its sloping sides either extending at at least two separate angles to the axis and/or lying on at least two separate curves.
Abstract: Pre-shaped wrought-iron rods are placed one beside another in a lattice array, in which node-forming portions of adjacent rods are disclosed close to each other at a plurality of node positions. All node-forming portions at each of said node positions are inserted into a U-shaped strip metal element having an inwardly protruding longitudinal rib. Each of said strip metal elements is joined to said node-forming portions inserted therein by a projection welding operation in which said rib is used as a projection. Each of said strip metal elements is subsequently closed to form a closed clip embracing said node-forming portions joined thereto.
Abstract: Mechanism for cutting and clinching leads projecting from circuit boards or the like is operable in two alternative modes: (1) clinching them inwardly, i.e. toward one another, and (2) clinching outwardly. Shifting of one part, a pin, for example, from one operating position in its cut-clinch assembly to another position conveniently converts the device to the operating mode desired.
