Improvements in the Ejecting Mechanism of Automatic and other
Fire-arms.
I, HUGH WILLIAM GABBET-FAIRFAX, of 107, Lambeth Palace Road, London,
S.E., Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has more especial reference to ejecting mechanism of the kind
wherein the ejector proper is operated by a sliding rod or bar which is acted
upon by the movement of the barrel or a sleeve in which the barrel is fixed or
by a projection or extension from either the barrel or the sleeve.
I provide the breech block or the sleeve in which the breech-block travels
with an ejector which is somewhat similar in shape to the extractor and is
situated diametrically opposite thereto. The ejector is capable of longitudinal
movement on the breech block and is provided at its free end with a shoulder
which is adapted to assist in supporting the cartridge and is so formed that a
portion thereof lies immediately behind the flange of the cartridge and on the
side of the flange opposite to that with which the claw of the extractor engages.
The sliding rod or bar may be provided with a projection near each of its ends.
one of such projections being adapted to be acted on by the sliding barrel and
the other being adapted to act upon the ejector when said sliding bar is shifted
by the barrel. The effect of this shifting of the sliding bar is to cause the
shoulder of the ejector to strike the base of the cartridge case on that side
remote from the extractor, thereby expelling the said case from the fire-arm.
I may altogether dispense with the sliding bar when I attach the barrel
firmly to the sleeve in which the breech block or bolt travels, or when I furnish
the barrel with a rearward extension fixed to it whether in the form of a sleeve
or not.
In either of these events I need only form a lug or stud on such extension
or sleeve which lug or stud will, after a certain amount of forward travel, strike
the projection on the ejector bar.
In fire-arms of the kind in which the cartridges are fed one by one in front
of the breech block by means of a pivoted arm or carrier or otherwise, I may
provide the breech block with a pair of ordinary extractor claws situated
diametrically opposite each other in a plane at right angles to that in which
the cartridges move in reaching the space in front of the breech block, so that
as each incoming cartridge enters the said space it will force out the empty case
that has already been extracted.

I, HUGH WILLIAM GABBET-FAIRFAX, formerly of 107, Lambeth Palace Road,
London, S.E., but now of 47, Portland Street, Leamington, near Birmingham,
in the County of Warwick, Civil Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement: --
This invention has more especial reference to ejecting mechanism of the
kind wherein the ejector proper is operated by a sliding rod or bar which is
actuated by the movement of the barrel (as set forth in the Specification of
my prior Patent No. 17672 of 1896) or of a sleeve in which the barrel is fixed,
or by a projection or extension on either the barrel or the sleeve.
According to my present invention I provide the breech block or bolt, or the
sleeve in which the breech-block or bolt reciprocates, with an ejector which is
situated diametrically opposite to the extractor or nearly so. The ejector is
capable of longitudinal movement on the breech block and is provided at its free
end with a shoulder which is adapted to assist in supporting the cartridge and
is so formed that a portion thereof lies immediately behind the flange of the
cartridge. The sliding rod or bar is actuated by the sliding barrel and in turn
acts upon the ejector as the said sliding barrel performs its forward movement.
The effect of this shifting of the sliding bar is to cause the shoulder of the
ejector to strike the base of the cartridge case on that side remote from the
extractor, thereby expelling the said case from the fire-arm through a suitable
ejection opening.
I may dispense with the sliding bar when I attach the barrel firmly to the
sleeve in which the breech block or bolt travels, or when I furnish the barrel
with a rearward extension whether in the form of a sleeve or not. In either
of these events I need only form a finger on such extension or sleeve which
finger will, as the barrel advances to its firing position operate the ejector bar.
The said ejector bar may likewise in some cases be dispensed with by making
the said finger resilient so that it will remain in an inactive position when
the barrel and breech block recoil but will, as the barrel advances to regain
its firing position and open the breech, assume a position to strike the base of
the cartridge case at a point opposite to the extractor, and thereby eject said
cartridge case.
In order that my invention may be clearly understood and readily carried
into effect I will proceed to describe the same more fully with reference to the
accompanying drawings in which:-
Figure 1 is a sectional plan of part of an automatic pistol provided with
one form of my improved ejecting mechanism;
Figures 2 and 3 are similar views shewing modified forms of the ejecting
mechanism.
Like letters of reference indicate similar parts in all the figures.
A is the barrel and A¹ the spiral spring by which it is caused to assume its
firing position after each discharge. B is the breech block and C the casing
within which such block reciprocates. D is the extractor and E is the ejector.
Referring more particularly to Figure 1, the ejector is mounted in a dovetail
or other groove formed in the side of the breech block so that it can slide longi-
tudinally therein without becoming unintentionally detached. e is a shoulder
formed on the free end of the said ejector, immediately behind the flange of
the cartridge at a point diametrically opposite to the extractor D. F is the
sliding rod or bar which works longitudinally in a dovetail groove formed in

page_text: the casing C and which has projections f f at its ends. As the barrel moves
forward to regain its firing position and open the breech after discharge, it acts
on the projection f and moves the bar F forward; the projection f¹ then strikes
the ejector which jerks out the cartridge in an analogous manner to that set
forth in my aforesaid prior specification. To cause the ejector to resume its
original position after each ejection I provide it with a lug e which lies between
the projection f¹ and another projection on the sliding-bar F. After the
said ejector has been carried forward by the projection f¹ to eject
the empty cartridge case, the lug el on the ejector will meet the
other projection fas the breech block advances to close the breech,
whereby the ejector will be restrained from further forward movement while
the breech block continues to advance, thereby bringing the ejector into its
original position. I may however employ a spring e for returning the ejector
to its normal position as shewn in Figure 2.
Referring now to Figures 2 and 3, the barrel is represented with a sleeve A³
within which the breech block reciprocates, such sleeve participating in the
movements of the barrel. In this case the breech block is unprovided with a
rotative locking head of the kind referred to in my aforesaid prior specification,
the entire block being adapted to partially rotate to effect its locking and un-
locking to and from the barrel, such partial rotation being, if desired, effected
in an analogous manner to that explained in said prior specification. In Figure 2
the breech-block is provided with an ejector which slides thereon as in the
arrangement illustrated in Figure 1 but instead of employing a movable bar F
for operating the ejector, I provide on the sleeve A³ the finger or projection a
which serves the same purpose as the projection f¹ in the previous arrangement.
In Figure 3 I have replaced the aforesaid finger or projection by a spring or
resilient finger at which is located in a cavity a¹ in the sleeve A. The free
end of this resilient finger is adapted to enter a recess in the head of the
breech block as the barrel advances to its firing position, whereby said resilient
finger gets behind the flange of the cartridge case, at a point diametrically
opposite to the extractor D), and ejects said case; the breech block at such time
remaining stationary. As the breech block afterwards advances to close the
breech, the said finger by its resiliency gives way and enters the cavity a²
wherein it lies until the breech block and barrel become separated again at
the next discharge. In this construction I am consequently enabled to dispense
altogether with the sliding ejector on the breech block as well as with the
sliding rod F.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a fire arm having a sliding barrel and breech block or bolt, the ejector
arranged on the said bolt relatively to the extractor as described and adapted to
be moved relatively to the bolt by the action of the sliding barrel for the purpose
specified.
2. The combination with the sliding barrel and the extractor of a resilient finger
on an extension or sleeve forming part of the barrel for the purpose specified.
3. A fire arm provided with ejecting mechanism, constructed arranged and
operating substantially as described with reference to the accompanying drawings.
Dated this 18th day of February 1899.
