PROVISIONAL SPECIFICATION.
Improvements in Breech-loading Small Arms.
I, WALTER STEVENSON LINDSAY, of 223 Rutherglen Road Glasgow, North
Britain, Architectural Draughtsman, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in breech loading small arms, and has
for its object to dispense with the second motion in charging, that is to say, the
closing of the breech by means of the lever. The invention consists in making the
slot in the pin or striker in which the tumbler works at an angle of say about 45º,
so that in opening the breech with the view of charging the rifle the tumbler
pulls the striker further back and tightens the spring, so that when it is released it
has a greater tendency to return the striker to its normal position. I make the
top part of the trigger shorter than at present to allow the tumbler more room
to play.
provide the extractor with a check to keep the block in position when the
breech is open, and I also provide it with a thumb-piece, so that while pushing the
cartridge home I at the same time by means of this thumb-piece release the block
off check and so close the breech.
By pressing the lever upwards the breech is opened, and while in the act of
pushing home cartridge the block closes and the lever comes into position again.

COMPLETE SPECIFICATION.
Improvements in Breech-loading Small Arms.
I, WALTER STEVENSON LINDSAY of 223 Rutherglen Road, Glasgow, North
Britain, Architectural Draughtsman do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention relates to improvements in breech loading small arms, and has for
its object to dispense with the second motion in charging, that is to say the closing
of the breech by means of the lever. The invention consists in making the slot in
the pin or striker in which the tumbler works at an angle of say about 45°, so that
in opening the breech with the view of charging the rifle the tumbler pulls the
striker further back and tightens the spring, so that when it is released it has a
greater tendency to return the striker to its normal position. I make the top
part of the trigger shorter than at present to allow the tumbler sufficient room
to play.
provide the extractor with a check to keep the block in position when the
breech is open, and I also provide it with a thumb piece so that while pushing the
cartridge home I at the same time by means of this thumb piece, release the block
off check and so close the breech.
By pressing the lever upward the breech is opened, and while in the act of
pushing home cartridge the block closes and the lever comes into position again.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings which I will now
proceed to describe.
Figure 1 is a section showing rifle with the breech closed ready for firing.

page_text: Figure 2 is a similar view showing rifle with the breech open.
Figure 3 is a front view of the extractor and thumb-piece.
A is the block; B the block axis: C the striker; D the main spring; E the
tumbler F the indicator axis; the trigger: H the trigger spring; I the trigger
guard: the lever K th extractor: L the extractor axis.
In carrying my invention into practice I make the slot a in the striker C in
which the tumbler E works at an angle of about 45°, so that when the breech is
being opened in order to be charged the tumbler E will pull the striker (' further
back and tighten the spring D, thus ensuring the striker returning to position
for firing, and in doing so it assists in closing the breech. I also make the trigger G
with a smaller projection at the top in order that the tumbler E may have sufficient
room to play as the tumbler is brought further back, as seen more particularly in
Figure 1. provide the extractor K with a check to retain the block A in
position when the breech is open, and also provide it with a thumb piece c
(Figure 3) so that when pushing the cartridge home I at the same time by means
of this thumb piece e release the block A. off the check band so close the breech.
In order to open the breech press the lever J upwards, and while in the act of
pushing home the cartridge the block A. closes as herein before described and the
lever returns into position again, being assisted with spring M.
When it is desired to lock the trigger GI provide a sliding bar d, having a
downward projection to enable the bar to be pushed along under the spring H
until it comes into the recess in the trigger G.
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 breech loading small arms, making the striker in which the tumbler works
at an angle of about 45°, substantially as and for the purposes hereinbefore described
and shown on the accompanying sheet of drawings.
2. In breech loading small arms, making the top part of the trigger shorter
than at present, substantially as and for the purposes hereinbefore described and
shown on the accompanying sheet of drawings.
3. In breech loading small arms, constructing the extractor with a check and a
thumb piece, substantially as and for the purposes hereinbefore described and shown
on the accompanying sheet of drawings.
4. In breech loading small arms providing a sliding bar for locking the trigger,
substantially as and for the purposes hereinbefore described and shown on the
accompanying sheet of drawings.
Dated this 14th day of October 1891.
