Abstract
Abstract A safety device for a firearm which is adapted to be received in the breech of the firearm and which has a retaining member located in but extending through the body thereof, which retaining member can either be in a condition where it is in contact with the breech and acts to prevent outward movement of the device, to a position where it does not obstruct any such outward movement, whereby the safety device can be readily removed from the breech. Preferably, the two positions of the retaining means are controlled by a key operated lock.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
A safety device having a body which is of a diameter and length to be received in a breech of a firearm having a barrel and extend a substantial part of the length of the breech, retaining means located substantially in the body, said retaining means being a resilient plate which extends outwardly through at least one aperture in the body to contact a wall of the breech to restrict outward movement of the device relative to the breech, the plate being deformable so that its effective length can be varied from a length that does not frictionally engage with the breech to a length where there is frictional engagement, and means to act on the retaining means to cause it to adopt one of the two positions.
Claim 2
Dependent Claim
128 words
A safety device having a body which is of a diameter and length to be received in a breech of a firearm having a barrel and extend a substantial part of the length of the breech, retaining means located substantially in the body, said retaining means being a resilient plate which extends outwardly through at least one aperture in the body to contact a wall of the breech to restrict outward movement of the device relative to the breech, the plate being deformable so that its effective length can be varied from a length that does not frictionally engage with the breech to a length where there is frictional engagement, and means to act on the retaining means to cause it to adopt one of the two positions.
Claim 3
Dependent Claim
33 words
A safety device as clamed in claim 1 wherein the retaining means passes through two substantially diametrically opposed apertures in the body and can frictionally engage the breech on two opposed sides thereof.
Claim 4
Dependent Claim
41 words
A safety device as claimed in claim 2 wherein the retaining means has two arms which are located at an obtuse angle to each other, the extension in length being achieved by relative movement of the arms towards a common plane.
Claim 5
Dependent Claim
84 words
A safety device as claimed in claim 3 wherein the actuating means include a pin which is mounted for rotation about an axis substantially normal said common plane of the resilient plate and which can adopt two positions, in one of which it lies along the line of connection of the two arms, so the arms can adopt their rest condition and, in the other of which, it lies along the axis of the arms causing deformation of the arms towards said common plane.
Claim 6
Dependent Claim
34 words
A safety device as claimed in claim 4, wherein the pin is diametrically located on a shaft which is associated with a lock mechanism whereby the pin can be rotated between its two positions.
Claim 7
Dependent Claim
27 words
A safety device as claimed in claim 1 wherein the end of the body which is directed towards the barrel is provided with a shock absorbing assembly.
Claim 8
Dependent Claim
34 words
A safety device as claimed in claim 6 wherein the shock absorbing assembly includes an helical spring located in the end of the body and an outwardly directed member which acts against the spring.
