PNEUMATIC NAILING TOOL

Pneumatic nailer

ABSTRACT OF THE DISCLOSURE In a pneumatic nailer using compressed air for driving nails, a work chamber contains a drive piston and is in communication with a storage chamber for effecting the return of the drive piston after it has driven a nail. A valve unit controls the supply of additional compressed air into the storage chamber. A switching element is ar-ranged to react when a predetermined compressed air pres-sure is exceeded for controlling the flow of compressed air through the valve unit to the storage chamber. The switching element can be a pressure limiting valve. The combination of the switching element and valve unit a-voids unnecessary compressed air losses in the higher pressure operating ranges.

Magazine for caseless propellant charges

ABSTRACT OF THE DISCLOSURE A magazine for caseless propellant charges, such as used in a fastening element setting device, consists of an elongated strip-like member. Cut-outs are provided in the strip-like member and a caseless charge and the holder in each cut-out by webs. A caseless charge and the holder are displaced out of a cut-out when a sufficient force is directed against the holder to separate the webs from the strip-like member.
