PROVISIONAL SPECIFICATION.
Improvements in Quick Firing Guns.
I, AXEL WELIN of 9 London Street in the City of London, Mechanical
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to guns in which the breech block is withdrawn from the
breech after being unlocked by being swung round a pivot.
In order to give to the extractor great power at the beginning of its movement
and rapid travel at the end I pivot it near its nose to two links which are them-
selves pivotted to the gun by a pin passing through a slot in the extractor. The
extractor is operated by a cam surface on the axis of the arm carrying the breechi
block which bears against its tail end. During the first part of the movement the
extractor turns about the pivot carried by the links the latter being prevented from
moving by an abutment, when however the end of the slot comes to the pin the
extractor turns about this, carrying the links with it.
I dispense with the screw gear sometimes used for rotating the breech block and
do this by a rack sliding transversely to the gun in a slot or guide in the arm
carrying the breech block. This rack is traversed by a pinion on the axis of the
handle and carries a pin or roller at its end which engages with a curved slot in
the breech block. The beginning of the slot is tangential to the block and its end
radial so that the block is turned with an increasing speed and diminishing power.
When the breech block has been fully unscrewed the rack is prevented from
moving further by a stop and directly the arm with the block begins to swing away
from the gun the rack is prevented from moving back again as its end abuts
against the bearing (fixed to the gun) in which the axis of the arm works. The
rack therefore not only operates the block but also locks it when the breech is
open. The stop is secured by a screw from the rear face of the carrier arm. By
undoing this screw the stop can be removed and then by turning the breech block
by hand the rack is drawn out.
In order to allow the gun to be recocked without opening the breech, I carry the
firing pin back to the rear end of the breech block and I preferably provide a
sleeve around its end to serve as a handle. When the firing pin is pulled back the
spring of the trigger bar turns it in the sleeve and causes a lug upon it to engage
with a recess in the sleeve and so retain it in the cocked position.
Dated this 17th day of January 1896.

QUICK
I, AXEL WELIN of 9 London Street in the City of London, Mechanical
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 relates to guns in which the breech block is withdrawn from the

page_text: 3. The combination of a gun, an arm pivotted to the gun its pivot being at right
angles to the axis, a breech block pivotted to the arm and locking in the gun by a
partial turn, a lever pivotted to the arm its pivot being parallel to that of the arm,
a rack carried by the arm, and actuating the breech block and a pinion on the lever
gearing with the rack.
4. In apparatus such as is referred to in Claim 3 causing the end of the rack to
abut against a part fixed to the gun when the arm is being swung back.
5. The combination with the firing mechanism referred to in my former
specification of a firing pin carried to the rear face of the breech block.
6. Quick firing guns substantially as described and shewn in the drawings.
Dated this Third day of October 1896.
