  • Patent number: 7946462
    Abstract: A slide frame is mounted on a driver unit that can be vertically reversed on a base frame. A guide pin disposed in the slide frame engages with a concave portion of a cam plate portion formed in the base frame. When a fixation releasing handle of the driver unit is operated, a lever pushes the slide frame to slide the slide frame and the guide pin is deviated from the concave portion to rotate the driver unit. In a state where the driver unit is fixed in a regular posture, since the guide pin is pushing a switch lever, the detection switch is kept turned ON and thus an electric stapler is in an operable state. When the driver unit is rotated, the switch lever is released from the press of the guide pin and the detection switch is turned OFF, thereby cutting off the power.

The installation tool has a hollow barrel with a nose piece at its working end for receiving and releasably holding each rivet delivered thereto. Two piston assemblies are slidably mounted in the hollow barrel: one maintains the rivet body stationary against the workpiece and the other has jaws thereon for gripping and pulling on the rivet mandrel to expand the rivet body and break away the mandrel. The hollow barrel also contains a vacuum tube through which broken-away mandrels are expelled.

  • Patent number: 4676421
    Abstract: A point of operation safety device for hydraulic or pneumatic presses. The safety device is computer controlled and limits the movement of the punch by employing two sensing devices. These sensing devices include both position and contact sensors which are used as dual input variables to satisfy computer monitored operational condition limits which, if not met, shut down the operation of the machine to prevent accident or injury to the operator. Both sensing devices are located within the housing of the press and the ram assembly so that no additional structures are required which might obstruct the working area and thereby hinder the efficient use of the press. Because the components of this safety device are located within the body of the machinery and include complicated electronic control circuitry, it is impossible to defeat the safety mechanism by disconnecting any of the components.

  • Patent number: 4650104
    Abstract: A positioning device comprises a reciprocably movable support table having a surface extending in a plane above a clinching die of a button setting machine for supporting a garment fabric to which a button is to be attached, and a pair of guide members disposed on the surface in perpendicular relation. The table includes a recess which is registry with the clinching die when the table is in an advanced position. One of the guide member is positionally adjustable in a direction perpendicular to the direction of movement of the table and the other guide member is positionally adjustable in a direction parallel to the direction of movement of the table. Thus the garment fabric can be positioned accurately and easily with respect to the clinching die by simply putting two adjacent edges of the garment fabric into guided engagement with the respective guide members.
