Abstract: There is disclosed a surgical stapler. An anvil is mounted on a distal end portion of an elongated body of the stapler. A guide member supports a number of staples disposed in contiguous relation to one another. The staples are urged toward the anvil by an urging mechanism. A ram is mounted on the body for movement along the longitudinal axis of the body. A lever is pivotally mounted on the body, and the pivotal movement of the lever is converted into a rectilinear movement of the ram by a motion converting mechanism. The ram, when advanced, cooperates with the anvil to deform the staple disposed in a path of movement of the ram. In order to achieve a lightweight and small-size construction of the stapler, the lever is pivotally connected at its proximal end to the proximal end portion of the body so that the lever is pivotally movable toward and away from the body, and a distal end portion of the lever serves as a manipulating portion.

A relatively deep throat is thereby afforded for sheet metal which may be inserted between said punch mounting means and said anvil support-means. Anvil-support suspension mounting means are provided on the upper part of the frame to allow a further anvil support to be suspended from that part of the frame, whereby smaller work can be operated on by the machine.

Abstract: A stapling device utilizes heat recoverable material (the driver) having shape memory to drive staples through materials to be joined and in one embodiment, against an anvil for crimping the ends of the staples. The heat recoverable material, preferably a metal such as Nitinol, may have heat applied by a heater mounted on at least one surface thereof or by induction or other method of heating. If a heater is mounted on a surface of the driver, upon insertion of the driver into the staple device, the heater makes electrical connection with terminals for connection to a supply circuit. In a specific embodiment staples may be provided, fabricated from heat recoveralbe metal so that each staple may carry its own heat recoverable, staple driving element. The staple tines may have a heat recoverable shape with the ends of the tines directed toward one another so that staple closure occures as heat migrates from the staple driving region to the tines thereof.

Abstract: A device for driving nails and similar fastening elements includes a driver rod performing a reciprocating stroke-like movement for placing the nails. A rotating driving element transmits the driving power to the driver rod so that it carries out the stroke-like movement. During the nail driving operation, the rotating driving element is coupled with the driver rod by a carrier. The carrier is secured to the driving element and moves along an elongated path in converting the rotational movement of the driving element into the stroke-like movement of the driver rod.

In its preferred embodiment, the power adjusting a mechanism includes a manually adjustable selector knob having a cam element, and includes a cam follower mounted in association with the upper end of the solenoid core. Rotation of the selector knob adjusts the length of the solenoid power stroke and the resulting driving power of the stapling tool.

Abstract: The specification discloses a forming die or ram movable along a guideway or track by a pair of toggle-joint linkages to move from a column of staples a staple having a downwardly bowed central portion into engagement with an anvil, then bend outer portions down over the anvil to drive pointed legs into the flesh and bring the legs into alignment with each other. The column of staples is pressed by a spring arm and a follower toward the track and is laterally supported in a staple magazine. Each toggle-joint linkage is a one-piece member with two rigid arms connected by an undulating spring portion. The magazine is detachably connected to the track by spring latches or clips. Another stapler has a hook-like anvil, and the bowed central portion of the staple as it is pressed against the anvil by a forming die or ram, is first straightened and then bent legs are bent from the central portion, thus giving a "soft" initial feel to the stapling.

Abstract: Machine for attachment of rivets, buttons or the like, particularly to clothing pieces, with an upper tool traveling towards the lower tool, which upper tool sits on a vertically guided upper tool ram. The working stroke of the ram is achieved by means of an inclined surface of a wedge, the latter entering between a roller of the ram and an abutment on the machine side, with the inclined surface of the wedge running on the roller.
