The invention is particularly suitable for fastening tools.

Abstract: According to the invention, which applies to a gas-operated apparatus comprising a first chamber for the precompression of a combustible gas injected thereinto and generation of a flame, and a second, propulsion, chamber, and placing elements, the two chambers in communication, these elements being designed to allow the flame to pass, the power of the apparatus is adjusted by adjusting the communication between the two chambers. The volume of gas injected directly into the propulsion chamber can also be adjusted. Alternatively, the rotational speed of the fan with which the first chamber is equipped can be adjusted.

The operating sleeve comprises a securing wedge that lies through a window formed in the tubular element and through which the linkage runs.

Abstract: A strip includes fasteners (1), each having a shank (2) which is pointed at one end (4) and bears a head (3) at the other end. The fasteners are respectively engaged by their shanks (2) in guide and damping blocks joined together in a string (8). The strip further includes a second guide string (9).

Abstract: 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.

Abstract: The apparatus is intended to drive fasteners (21) for fastening a piece (20) to a support (30). The apparatus has a snout (12) equipped with a bearing shoe (14). The shoe is equipped with lateral positioning one-piece plate (15) on which there are formed a number of distinct lateral bearing surfaces (8, 8?, 8?, 8 82, 83) roughly parallel to the axis of the snout to be applied in particular to an edge of one of the pieces either the support piece or the piece that is to be fastened.

Abstract: The sealing apparatus (100) is used in a substantially vertical position by the user, who inserts a magazine pack containing nails into the hopper (101). After unlocking of the hopper (101), the nails slide in the flexible feed tube (10) as far as the front of a feeder for indirect firing, in a buffer guide (102). The user then merely has to actuate a trigger (103) in order to entrain the nails into the support via the feeder. In order to preserve the transparent quality of the tube (10), its effective inner cross section (21) is not circular, but is arranged (23) such that the contact between the lateral wall of the circular head of the nail (1) and the effective inner wall (21) of the tube (10) is not possible on certain portions (22) of the effective inner wall (21).
