Olin Mathieson Chemical Corporation, New York, N.Y., V.St.A. Device for driving fastening bolts into walls

Priority: September 8, 1961, Australia, No. 8996/61

The invention relates to an apparatus for driving metal fasteners operated by firing an explosive charge in walls or solid material. One of the most important requirements for such devices is that they are safe are ready for use at all times, and are easy to load with the mounting bolts and cartridge. The device should also be light to be unloaded again and have the lowest possible recoil, it should be provided with a trigger as well as from be of stable construction, can also be used in spatially limited places and be inexpensive to manufacture as a mass-produced item, but robust in use.

According to the invention, the device operated by explosive force a loading block that can be rotated or hinged with respect to the device body to conveniently load the explosive charge can, the fastening means to be shot is inserted from the front into the device.

According to another embodiment according to the invention, the charging block is removed transversely from the device body in order to charge the device.
Preferably, the loading block is hinged about a longitudinal axis against the handle and firing mechanism of the device

movably mounted.
, The main feature of the invention is to provide a device of the type described in which the handle against the loading

■ t

block can be moved to the La <Jeblock in its closed Lock position.

Another feature is that the handle of the device is designed in such a way that the device body can spring back into the handle when the explosive charge is ignited and the recoil is dampened by it.

Another feature of the invention is that a trigger mechanism is intended to operate the device, and securing clamping devices are used, which are only then operated when the device is ready for launch. Another feature is that a piston is provided, which is switched off when the firing device with explosion drive is actuated with a shock absorber acting as a simple nozzle is to dampen the impact of the piston movement and bring it to a standstill.

Another feature of the invention is that acting like a simple nozzle means are provided to throw the used cartridge out of the cartridge chamber and return the piston to its starting position after the device has been fired detailed description of the mode of operation of an embodiment'-evident · Pig. 1 shows a perspective view of the device

The method of operation of the fastening tool is then explained described.

In order to reload the fastening tool when the piston 86 is in the retracted position and the loading blank 32 is open, a suitable fastening means is pushed into the enveloping Mansohett 35 and pushed forward into the bore 38 in the guide sleeve Z> 2 . Then a cartridge with a suitable charge is pushed into the cartridge box 88 and the loading block 22 is closed.
