driving spring

Getting tough on drinking and driving Spring brings with it a deadly trend in Saskatchewan.

The driving spring then forces the piston rearward, which reverses the action and returns the bolt to battery.

By inserting the fingers into the empty chambers and rotating the aluminium cylinder it is then wound against its driving spring.

All these wheel sets have been refurbished to main line running standard, as have the twelve axle boxes and the driving springs.

The lock frame was retracted by recoil action during automatic firing and is forced forward by the driving springs.

The first version was made at Hanygan with a hand-made driving spring, the second was manufactured at Pratt & Whitney and had a machined spring.

The driving spring assemblies held the lock frame against the carrier dog until the carrier was released by carrier catch which was pivoted by the incoming round.

A slight delay in primer function, and the gun reverts to a simple blowback without the benefit of a massive bolt and stiffer driving spring to soften the recoil impact.

The recoiling mechanism of the gun included the tube and tube extension, recuperator piston and piston rod, lock frame assembly, driving spring assemblies, and the breechblock assembly.

Early M60s also had driving spring guides and operating rods that were too thin and gas pistons that were too narrow behind the piston head (part of an attempt to save weight), leading to problems with breakage.
