A pin for fixing a panel to a support material is provided, having a shank (1) and a head (4), and a narrowed anchorage portion (5), a washer (2) for pressing the panel to be fixed against the support material and a guide (3) for limiting the penetration depth the shank (1). The pin, to be anchored within a material supporting the panel by means of a powder actuated tool does not damage the panel and ensures fixing of the pin with very good quality The guide (3) comprises a cylindrical tube which forms a hole within the panel, within which the cylindrical tube guide (3) is disposed so as to serve as a guide for the shank (1) of the pin as the same is being driven therethrough and into the support material.

A magazine-indexing mechanism for a powder-actuated tool, of the type adopted for use with a disk-shaped cartridge magazine, is actuated by the same trigger displacement as actuates the firing mechanism. A first link, pinned to the receiver, and a second link, pinned to an extension of the trigger, are pinned together, with a magazine engaging hook disposed on the dictal end of the first link. When the trigger is pulled, as to fire the tool, the hook is displaced to engagement with the magazine. When the trigger is released, the engaged hook is displaced, indexing the magazine. Means are also provided to prevent indexing an unfired cartridge through the tool.

Apparatus for driving fasteners includes a barrel, a fastener guide which retreats as the apparatus is pressed against a substrate, a feed magazine, receiving a loader of fasteners, and a safety element configured to allow a fastener to be driven only after the fastener guide has retreated. There is a safety shoe configured to, when there is no fastener in the barrel, be moved into a safe position and prevent the retreat of the fastener guide, and including a tell-tale of the safe position of the safety shoe.

The apparatus comprises a barrel (1), a plunger (4) movable in the barrel for driving a fixing element (6), a plunger return catch (9), an element guide (21) mounted pivotably at the front of the barrel in order to load an element (6) therein from the rear to the front. The guide (21) is movable in axial translation relative to the barrel (1) and can move back into the firing position towards the barrel (1) and cover the front end of the recess (13) of the plunger (4), in order to then cover the head (14) of a fixing element (6) previously introduced into the guide (21).The apparatus of the invention is well adapted to the application of plugs in steel or concrete materials.

A marking device is provided so as to be movably mounted upon the mouth or open end of the barrel (1) of an explosive or propulsive driving apparatus. It comprises a flexible case (11) fixed upon an anvil (10) which is intended to transmit the energy of the piston (4) of the apparatus to a series of punches (14) disposed within the case and whose stroke is controlled by means of a damping pad (19) which is resiliently deformed during marking.

The invention provides an indirect firing fastener driving apparatus with adjustable firing power, including within a barrel holder, a barrel, a piston mounted in frictional contact within the barrel, and a pawl for retaining the piston. A ring, held against rotation in the barrel holder, is screwed onto the barrel. The ring cooperates with a free projecting into the barrel so that relative threading of the ring relative the barrel moves, through means of contact of the stop with the pawl, the position of the piston within the barrel when the barrel is pulled forwardly.

The apparatus, provided for undersea work, includes a barrel holder, a barrel for guiding a fastener intended to be driven by the gases of a propulsive charge and a percussion system for setting off the charge. The percussion system includes a striker, a bolt for cocking the striker, a tumbler for releasing the bolt, a trigger for actuating the tumbler and a chamber having a liquid intake orifice and a suction orifice. The tumbler is movable in the chamber and the trigger, when operated, closes the intake orifice, pushes back the liquid and moves the tumbler thus allowing percussion of the charge. Upon return of the trigger into the rest and rearming position, the suction orifice makes possible to compensate the leaks in the chamber and to use the apparatus again.

The tool comprises between a barrel and a breech, a rotating loader disc provided with orifices for receiving propellant charges. Between these charge-receiving orifices there are orifices for inhibiting the sympathetic ignition of the adjacent charges.

The strip comprises fasteners (1), each having a shank (2) which is pointed at one end (4) and bears a head (3) at the other end, these fasteners being respectively engaged by their shanks (2) in guide and damping blocks joined together in a string (8). The strip comprises a second guide string (9). The loader comprises a chamber (13) for accommodating the fastener heads (3), a chamber (14; 13) for accommodating the first string (8) and a chamber (14; 15) for accommodating the second string (9), the chambers being connected in pairs by hollow shafts (16, 17) that accommodate the fastener shanks (2).
摘要:
In the apparatus, a fastening element is driven into a support under the action of the gases from an explosive charge via a piston (2) that can move in a gun between a firing position and a fastening position, and a plug guide (5) in which a piston-braking ball (6) mechanism is mounted, which comprises arms (7) mounted to pivot on the plug-guide (5) arranged to modulate the radial force of the balls (6), depending on the relative displacement of the gun (3) and of the piston (2), between a maximum force when the piston (2) moves forward in the gun, and a non-zero minimum force, when the piston (2) moves back.
