IMPROVEMENTS IN FIRE-ARMS CALLED REVOLVERS
Year: 1855

page_text: LETTERS PATENT to Frederick Blacket Edward Beaumont, of Upper
Woodball, Barnsley, in the County of York, Lieutenant, Royal Engineers,
PROVISIONAL SPECIFICATION left by the said Frederick Blacket Edward
Beaumont at the Office of the Commissioners of Patents, with his
Petition, on the 20th February 1855.
I, FREDERICK BLACKET EDWARD BEAUMONT, of Upper Woodball, Barnsley,
in the County of York, Lieut', Royal Engineers, do hereby declare the nature
of the Invention for "IMPROVEMENTS IN FIRE-ARMS CALLED REVOLVERS" to be
as follows:-
This Invention consists of a peculiar combination of the parts of a lock
of a fire-arm, by which the hammer may be cocked by hand or by pulling the
trigger. For this purpose, the hammer, in place of being separate from, is
connected to the trigger; hence, when the trigger is moved back, the hammer
is raised. The trigger has also combined with it similar apparatus to what
has heretofore been used in locks of fire-arms for acting on the hammer to
put it back (when not cocked) by pulling a trigger; hence, a fire-arm will at
all times be in a condition (supposing a cap to be on the nipple) to be dis-
charged by the trigger, either after first cocking the hammer by hand, or by
simply pulling the trigger to raise the hammer and to discharge it. At the
same time, whether the hammer is raised by the trigger or otherwise, the
barrels will be caused to revolve, as heretofore.

Patent Office on the 19th July 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
BLACKET EDWARD BEAUMONT, of Upper Woodball, Barnsley, in the County of
York, Lieutenant, Royal Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of February, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Frederick Blacket Edward Beaumont, Her special licence that I, the
said Frederick Blacket Edward Beaumont, my executors, administrators, and
assigns, or such others as I, the said Frederick Blacket Edward Beaumont,
my executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN FIRE-ARMS
CALLED REVOLVERS," upon the condition (amongst others) that I, the said
Frederick Blacket Edward Beaumont, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Frederick Blacket Edward Beaumont,
do hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say):-
This Invention consists of a peculiar combination of the parts of a lock of
a fire-arm, by which the hammer may be cocked by hand or by pulling the
trigger. For this purpose, the hammer, in place of being separate from, is
connected to the trigger; hence, when the trigger is moved back, the hammer
is raised. The trigger has also combined with it similar apparatus to what
has heretofore been used in locks of fire-arms for acting on the hammer to
put it back (when not cocked) by pulling the trigger; hence, a fire-arm will
at all times be in a condition (supposing a cap be on the nipple) to be dis-
charged by the trigger, either after first cocking the hammer by hand, or by

page_text: Simply pulling the trigger to raise the name and to
ge
same time, whether the haminer is raised by the trigger or otherwise, the
barrels will be caused to revolve, as heretofore..
Having thus stated the nature of my said Invention, I will proceed to
describe the manner of performing the same.

DESCRIPTION OF THE DRAWING.
Figure 1 shews a section of a revolving pistol having the lock-constructed
and arranged according to my Invention; the mechanical parts being shewn
in the position they assume immediately after the fall of the hammer. Figure 2
shows another section of the same parts, wherein the mechanical instruments.
are shown in the positions they assume when the click f has just left the notch
g, that is, immediately after commencing to pull the trigger, if the hammer
has been cocked by hand, and the parts are likewise nearly in 'the positions
they assume immediately the trigger has put back the hammer, if the
hammer has not been cocked by hand, the main spring being in the act of
forcing down the hammer. The other Figures shewn in the Drawings are of
some of the different mechanical instruments or parts separately. The
revolving barrels are not shewn in either of the Figures, in order that the
other parts-may be more clearly shown. a is the trigger, which moves on its
axis 6, and it is constantly pressed on by its spring c. The trigger, by means
of the click or driver d, when pulled acts on the notch e, and raises or cocks
the hammer from the position shown in Figure 1 to the position Figure 2,
where the click or driver is shown as having forced back the hammer, and as
having passed the notch e, so that the hammer is free to descend on the nipple,
and in these respects the arrangement of parts is substantially the same as
revolver locks now manufactured by Messrs. Deane, Adams, & Co.; and
it is to be understood that the peculiarity of the present Invention is, that in
addition to the power of discharging the contents of the barrels of a revolver
in succession by the simple act of pulling the trigger, this fire-arm has also
power of admitting the hammer to be cocked by pulling back the hammer
by the thumb, in a similar manner to other fire-arms. For these purposes it is
necessary to employ an instrument or apparatus, which (when the hammer
is pulled back or cocked, independently of the trigger,) shall connect the
hammer with the trigger, and cause it to act on the trigger and move it into
position to enable it when pulled to discharge the click or stop which retains
the hammer at cock. This connection between the hammer and the trigger
may be varied in form or detail, but I employ the parts shown. f is a lever
click or catch, pressed on by a spring, as is shewn. This lever click, when
the

page_text: the hammer is moved back by the thumb, enters the notch g, and retains the
hammer at cock. h is the driver, which causes the barrels to be revolved on
their axis j, in the manner heretofore practised by Messrs. Deane, Adams, &
Co. i is a spring, which is fixed to the driver h, and passes down below the
pin joints (by which the driver h is connected to the trigger); the spring i
is then bent, or it has a projection at right angles to it, which presses on the
tail of the driver d; hence, the driver d (which is pin-jointed to the trigger)
is constantly pressed towards the hammer. I is a hook or projection, fixed to
the lower part of the hammer, which enters a slot formed in the driver d;
hence, the hammer and the trigger are constantly connected together by
means of the parts l, d, and in such manner, that when acting through the
trigger on the hammer, the part d simply acts as a driver to put back the
hammer, as was formerly the case; but by reason of connecting the part d by
the part with the hammer, the part d is made to act also as a drag link
between the trigger and the hammer when the hammer is cocked by the
thumb. The upper part of the driver d releases the lever clicks from
the notch g in the hammer when the hammer is discharged after cocking it
by the thumb. The click ƒ does not act on the hammer when the hammer
is put back by the trigger. It may be observed, that when the hammer is
cocked by hand, it goes somewhat further back than when put back by the
trigger; hence, when putting the hammer back by the trigger, the click ƒ does
not fall into g. I would remark, that I do not claim to raise and discharge
the hammer of a "revolver" by the action of the trigger and apparatus con-
nected therewith when separately considered, neither do I claim to arrange
the lock of a "revolver" in such manner that the hammer may be cocked by
the thumb and also by the trigger; but what I claim is, the combining the
hammer and the trigger by means of parts d, l, f, acting as herein described.
In witness whereof, I, the said Frederick Blacket Edward Beaumont,
have hereunto set my hand and seal, this Fifth day of July, in the
year of our Lord One thousand eight hundred and fifty-five.
