PROVISIONAL SPECIFICATION.
Improvements in Revolvers and Four Barrel and Two Barrel
Pistols.
I HENRY AUGUSTUS SCHLUND, of Aston Cross, Birmingham, in the county of
Warwick, Civil Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements on the revolver action for which Letters
Patent were granted to me dated the 28th day of July 1885, No. 9084, part of the
said improvements being also applicable to four barrel and two barrel pistols.
The present improvements consist in providing the hammer of the revolver action
with a projection and also providing the sliding bolt which locks the barrel with a
slotted projection so that when the hammer is thrown forward in firing the projection
thereon comes against the said slotted projection on the sliding bolt, the point or fore
part of the hammer passing through the slot.
By this arrangement the hammer cannot fire the revolver unless the sliding bolt has
entered its notch in the rib of the barrel because if the said bolt fails to act the
hammer, when the trigger is pulled, will carry it forward into its recess.
I now form the trigger guard so that it encloses both the trigger and its lever or
cocking trigger and all the operating parts of the lock action (except the main spring
and sliding bolt) are attached thereto.
1 form the cocking sear with a catch adapted to engage and retain the lever or
cocking trigger when the latter is moved to cock the revolver the said catch being

page_text: kept pressed forward by a spring; the lever or cocking trigger is provided with a
sliding piece which is operated by the trigger when firing so as to press back the catch
of the cocking sear from engagement with the lever or cocking trigger.
By this arrangement it will be obvious that the revolver having been cocked it can
be uncocked without firing the arm by simply pulling back the said sliding piece
thereby allowing the lever or cocking trigger to move forward.
It will be obvious that the hereinbefore described arrangement of cocking sear and
lever or cocking trigger with sliding release piece arranged with mechanism on the
guard can with advantage be applied to a four barrel or two barrel pistol.

Pistols.
I HENRY AUGUSTUS SCHLUND, of Aston Cross, 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 relates to improvements on the revolver action for which Letters
Patent were granted to me dated the 28th day of July 1885, No. 9084, part of the
said improvements being also applicable to four-barrel and two-barrel pistols.
The present improvements consist in providing the hammer of the revolver action
with a lug or projection and also providing the curved sliding spring bolt which locks
the barrel, with a slotted projection so that when the hammer is thrown forward in
firing, the projection thereon comes against the said slotted projection on the spring
bolt, the point or fore part of the hammer passing through the slot.
I now form the trigger guard so that it encloses both the firing trigger and its lever
or cocking trigger and all the operating parts of the lock action (except the main
spring and sliding bolt) are attached thereto.

page_text: I form the cocking sear with a catch adapted to engage and retain the lever or
cocking trigger when the latter is moved to cock the revolver, the said catch being
kept pressed forward by a spring; the lever or cocking trigger is provided with a
sliding piece which is operated by the tail of the sear, the upper part of same being
acted upon by a projection on the breast of the hammer when firing so as to press
back the catch of the cocking sear from engagement with the lever or cocking trigger,
which will then move downwards.
In order to enable my invention to be fully understood I will proceed to
describe the same by reference to the accompanying drawings in which figure 1
represents a section partly in elevation of a revolver constructed according to my
present invention, the hammer being shewn at half cock and the barrel in its closed
position; figure 2 is a plan of the same; figure 3 is a similar view to figure 1, but
shewing the hammer at full cock; figure 4 is also a similar view to figure 1 but shewing
the barrel of the revolver in its open position; figure 5 is a rear elevation of the
barrel and the cylinder; figure 6 is a section on the line A, B, of figure 3; figure 7
is a side elevation of the trigger-guard and action; figures 8 and 9 are an elevation
and edge view respectively of the hammer; figures 10 and 11 are an elevation and
plan respectively of the trigger-guard; figures 12 and 13 are an elevation and plan
respectively of the rebounder; figures 14 and 15 are an elevation and plan respectively
of the firing trigger; figures 16 and 17 are a side elevation partly in section and an
end elevation respectively of the lever or cocking trigger; figures 18 and 19 are a
side elevation and an end elevation respectively of the lifter; figures 20 and 21 are
elevations of the sear; figures 22 and 23 are an elevation and a plan respectively of
the cocking sear and figures 24 and 25 represent a side elevation and an end elevation
respectively of the extractor. Similar letters of reference indicate similar parts
throughout the several figures of the drawings.
a, is the firing trigger; b, the rebounder; c, the sear, d, the lifter for actuating the
cartridge cylinder e, by means of the ratchet f, on the extractor g, and h, is the main
spring; h, is the recess in the rib h², of the barrel A, of the revolver, which recess
receives the curved spring bolt j, formed as hereinafter described for the purpose of
locking the barrel A. All the foregoing parts except the curved spring bolt j,
are of similar construction to those described in the Specification of my said former
Patent.
i, is the hammer and ¹, is the lug or projection with which I now provide it; ³, is
the projection which I also form on the breast of the hammer; 3, is the slotted
projection with which I provide the curved spring bolt j, which locks the barrel, so
that when the hammer i, is thrown forward in firing, the projection i³, on the said
hammer comes against the slotted projection j¹, on the spring bolt j, the point or fore
part, of the hammer i, passing through the slot in the projection j¹. By this
arrangement the hammer, cannot fire the revolver unless the spring bolt j, has
entered its recess h¹, in the rib h², of the barrel A, because if the said bolt fails to act,
the hammer i, when the trigger a, is pulled, will carry it forward into its recess h¹.
k, is the trigger-guard which I now form so as to enclose or surround both the
firing trigger a, and its lever or cocking trigger l, which is constructed in the manner
hereinafter described; all the operating parts of the lock action (except the main
spring h, and sliding bolt j,) being attached thereto as clearly shewn in figure 7, of the
drawings.
m², is the catch with which I form the cocking sear m, the catch being adapted to
engage and retain the lever or cocking trigger 1, when the latter is moved into position
to cock the revolver as shewn in figure 3; n, is the spring which I employ for keeping
the part of the sear having the catch m', pressed forward as shewn; o, is the sliding
piece with which the lever or cocking trigger 1, is provided and which is operated by
the tail c', of the sear c, striking its forward end when firing so as to press back the
catch m', of the cocking sear m, from engagement with the lever or cocking trigger l,
the upper part of the said sear c, being acted upon by the projection ³, on the breast
of the hammer when it falls, as will be readily understood.

page_text: By this arrangement it will be obvious that the revolver having been cocked as
shewn in figure 3 it can be uncocked without firing the arm by simply pulling back
the sliding piece o, by the finger and thumb so as to disengage the cocking trigger l,
from the catch m¹, thereby allowing the lever or cocking trigger 1, to move gently
forward into the position shewn in figure 1.
It will be obvious that the herein before described arrangement of cocking sear m,
and lever or cocking trigger l, with sliding release piece o, arranged with mechanisin
on the guard k, can with advantage be applied to a four-barrel or two-barrel
pistol.
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 revolver the combination with the slotted projection j', on the curved spring
bolt j, of the projection, on the hammer i, for ensuring the spring bolt being carried
forward into its recess ', when the revolver is fired substantially as described.
2. In a revolver action a trigger guard which encloses or surrounds both the firing
trigger a, and its lever or cocking trigger 1, and has all the operating parts of the lock
action (except the main spring and sliding spring bolt) attached thereto, substantially
as described.
3. In a revolver action the combination with the catch m¹, on the cocking sear m,
of the spring n, for keeping the said catch pressed forward, the sliding release piece o,
working in the lever or cocking trigger 1, and adapted to be operated by the tail of
the sear c, when firing so as to press back the catch m', from engagement with the
lever or cocking trigger 1, substantially as and for the purposes described.
4. In a four-barrel or a two-barrel pistol the combination with the catch m², on the
cocking sear m, of the spring n, and the sliding release piece o, working in the lever
or cocking trigger 1, and operated by the tail of the sear c, when firing so as to press
back the catch m², from engagement with the lever or cocking trigger 7, substantially
as and for the purposes described.
