What has been said of actions applies also to ejectors. If all the patents have not run out, plenty of good ones have done so, and the gun-maker has a great choice and nothing to pay for it.
The principle of the ejector is that with split extractors there is a connection between the fall of the tumbler or hammer and an ejecting mechanism, or lock in the fore end of the gun. The opening or closing of the gun after firing is made to cock the tumblers, strikers, or hammers, and also to put the ejector at full cock, or otherwise bring it ready for action, then when a shot is fired the fallen hammer or tumbler, or its re-cocking, is made to react on the ejector at that stage of the opening gun when the extractors have already moved the empty cartridge-case. The undischarged cartridges are therefore extracted, but not ejected, and the used cases are ejected.
Safety of Guns

The safety bolt placed upon hammerless shot guns is very necessary. It ought, when placed at safety, to prevent the lock springs working, and should prevent the possibility of the scear being released from the catch, or bent, or scear catch. Mr. Robertson, proprietor of Messrs. Boss & Co., has shown conclusively that a slight rap on the lock plates will disconnect any scear catch, and so let off the gun when not at safety, unless it is also protected with an interceptor, which is moved out of the way of the falling tumbler, or striker, only by the pull of the trigger. Mr. Robertson’s own single-trigger action is also a safety action, even when very light trigger pulls, such as 1 lb., are employed.
