Abstract
A spring closing assembly is disclosed which is adapted to be selectively installed and removed from a firearm. The illustrated spring closing assembly includes a rod having a free forward end which defines a slot dividing the free forward end into fork prongs. The assembly also includes a spring mounted on the rod, and a projecting part located on a first one of the fork prongs. At least the first fork prong is resiliently displaceable in an inward direction. The assembly also includes a washer dimensioned to be forced onto the free end of the rod by inwardly displacing the first fork prong. At least one of the projecting part and the washer is chamfered to promote the inward displacement of the first fork prong. The washer is captured between the projecting part and the spring.
Claims10
A spring closing assembly which is adapted to be selectively installed and removed from a firearm, the spring closing assembly comprising:
- a rod having a free forward end;
- an assembly part which is dimensioned to be pushed onto the rod;
- and
- at least one projecting part located in proximity to the free forward end of the rod, wherein the at least one projecting part is displaced from a resting position when the assembly part is pushed onto the free forward end of the rod and thereafter returns to the resting position with the assembly part mounted on the rod, wherein the at least one projecting part is in retaining engagement with the assembly part when (a) the at least one projecting part is in the resting position, (b) the assembly part is mounted on the rod, and (c) the spring closing assembly is removed from the firearm.
An assembly as defined in claim 16, wherein the assembly part is a ring washer for supporting the helical spring.
A spring closing assembly which is adapted to be selectively installed and removed from a firearm, the spring closing assembly comprising:
- a rod having a free forward end, the free forward end including a slot dividing the free forward end into at least two fork prongs;
- a spring mounted on the rod;
- a projecting part located on a first one of the at least two fork prongs, the first fork prong being resiliently displaceable in an inward direction;
- and
- a washer dimensioned to be forced onto the free end of the rod by inwardly displacing the first fork prong, wherein at least one of the projecting part and the washer is chamfered to promote the inward displacement of the first fork prong, and wherein the washer is captured between the projecting part and the spring.
A method of assembling a spring closing assembly comprising the steps of:
- providing a rod having a forked free end with a projecting part located on at least one prong of the forked free end;
- positioning a spring on the rod;
- initially pushing a washer on to the forked free end of the rod such that the projecting part is inwardly displaced;
- continuing to push the washer until the washer moves past the projecting part, the projecting part returns to a rest position, and the washer is captured between the projecting part and the spring.
