Year: 1853

page_text: LETTERS PATENT to William Tranter, of Birmingham, in the
County of Warwick, Gun Maker, for the Invention of "CERTAIN
IMPROVEMENTS IN FIRE-ARMS."
Sealed the 23rd March 1858, and dated the 28th January 1858.
PROVISIONAL SPECIFICATION left by the said William Tranter
at the Office of the Commissioners of Patents, with his Petition.
on the 28th January 1853.
I, WILLIAM TRANTER, of Birmingham. in the County of Warwick,
Gun Maker, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN FIRE-ARMS" to be as follows:-
My Invention consists, in the first place, in adapting and applying to
pistols and guns a double trigger or two triggers, one portion of the
trigger or one of the triggers being used for raising the cock, and the
other for discharging the piece. And with this trigger or triggers is
combined a safety stop spring to prevent the cock falling, until the catch
is withdrawn by means of the discharging trigger, or discharging
portion of the double trigger. This double trigger or pair of triggers

page_text: may be adapted in various forms to different constructions of fire-arms.
so as to accomplish in cach the double purpose of raising the cock, and
at the same time withdrawing the safety stop spring, together with the
discharging of the piece. The trigger or triggers may also have various
forms of guards adapted and applied to them.
My Invention consists, secondly, in elongating the tube or socket of
the revolving chamber in revolving pistols, through which tube or
socket passes the short rod or axis on which the chamber revolves.
The tube or socket may be slightly elongated. and the part of the frame
into which it is required to fit may be countersunk and prepared to
receive it in various ways, so as to increase the facility of applying the
revolving chamber to its position in the frane of the pistol, and prevent
the liability of the chamber to become inconveniently loose in its
position.
My Invention consists. thirdly, in combining the aforesaid double
trigger or pair of triggers with the chamber of a gun intended to be
loaded at the breech. In this case a strong spring is used, both to
hold the chamber in its place and to project the cock upon the nipple.
The chamber may be turned round far enough to insert a loaded
cartridge by pressing against a projecting lip and collapsing the spring,
and the cock may be allowed to strike upon the nipple by withdrawing
through the lifting trigger the means by which the projecting force of
the spring upon it was counteracted. In this case, too, the parts may
be retained on "half cock." The cartridge to be used in guns of this
description is one so constructed as to dispense with the necessity of
removing the closed end before placing it in the chamber by closing
the end with a percussion cap.
My Invention consists, fourthly, in combining the double trigger or
pair of triggers with the use of a needle or small rod to cause the
explosion, in which case the said needle or small rod is projected by
means of a spiral or other spring on the withdrawal of a bent lever
by the lifting trigger.
And my Invention consists, lastly, in making gun barrels out of two
or more spirals of iron or iron and steel wire platted or crossed round a
mandril, the wire so platted being afterwards heated to a welding heat.

page_text: and welded as in the ordinary manufacture of gun barrels. or it may
be rolled in such state and with a nandril inside between two flat
plates.

SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said William Tranter in the Great Seal Patent Office
on the 28th July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM TRANTER, of Birmingham. in the County of Warwick, Gun
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of January,
in the year of our Lord One thousand eight hundred and fifty-three,
in the sixteenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Tranter, Her
special license that I, the said William Tranter, my executors,
administrators, and assigns, or such others as I, the said Williamı
Tranter. 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 law-
fully might make. use. exercise, and vend. within the United King-
lom of Great Britain and Ireland. the Channel Islands. and Isle
of Man, an Invention for © CERTAIN IMPROVEMENTS IN FIRE-ARMS,"
upon the condition (amongst others) that T, the said William
Tranter, by an instrument in writing under my hand and seal.
hould particularly describe and ascertain the nature of the said In-
ention, and in what manner the same was to be performed, and
ause the same to be filed in the Great Seal Patent Office within
x calendar months next and immediately after the date of the said
etters Patent.
--
NOW KNOW YE, that I, the said William Tranter, do hereby
eclare the nature of my said Invention. and in what manner the

page_text: same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawings
hereunto annexed. and to the letters and figures marked thereon (that
is to say):
My Invention of "Certain Improvements in Fire-arms" relates, in
the first place, to the kind of fire-arms known as revolving pistols or
pistols with revolving chambers; and consists, first. in adapting and ap-
plying to such fire-arms a double trigger or pair of triggers, combined
with a safety stop spring, by means of which the piece is kept from
being discharged until the spring is moved out of the way of the cock.
which may be done simultaneously with the lifting of the cock and the
turning of the chamber by drawing back the lifting trigger or lifting
portion of the trigger with the second finger. The discharging trigger
may then be moved with facility by the first finger. and the cock pro-
jected on the nipple to discharge the piece. This trigger or triggers
may be used with various forms of guards. The lifting trigger or
lifting portion of the trigger is slotted to hold the discharging trigger or
discharging portion of the trigger. My Invention in relation to this
kind of fire-arms consists, secondly, in elongating the tube or socket
into which the hinder end of the revolving chamber is inserted, in
order that the chamber may be thereby screwed forward when required,
so as to keep the fore end always tightly fitting in the frame.
My Invention relates. in the second place, to guns intended to be
loaded at the breech, and consists in adapting and applying thereto the
double trigger or pair of triggers, somewhat modified in form as com-
pared with that above referred to, and in the general arrangement of
the parts of the gun, as herein-after more particularly described. In
the present instance the trigger is so formed as to be capable of holding
the gun at "half cock" by means of a tail piece on its end dropping
into a notch or recess in the lower part of the cock, by which
means the front or discharging part of this double trigger acts as a
single trigger. In this case the revolving chamber may be turned
round far enough to insert a loaded cartridge by pressing against a lip
the chamber. and collapsing the spring by which it is held in it,

page_text: place. The cartridge to be used in guns of this description is made so
as to have a percussion cap inserted in the end opposite to the ball, by
which the necessity for removing its ordinarily closed end may be
obviated.
My Invention relates, in the third place, to guns, in which the
arrangement and action of the revolving chamber and trigger or
triggers are similar to those last referred to. but in which the gun is
discharged by means of a needle or small rod projected by means of the
spring which holds the chamber in its place, or by means of a spiral
spring acting directly upon the rod carrying the needle.
And my Invention refers. lastly, to the mode of manufacturing gun
barrels, and consists in making them out of two or more spirals of iron,
or iron and steel wire platted or crossed round a mandril, the wire so
platted being afterwards heated to a welding heat, and welded as in
the ordinary manufacture of gun barrels.
In order. however, that my Invention may be fully understood I will
proceed to describe it more particularly by the aid of the accompanying
Drawings, in which are contained representations of the parts above
referred to.
Figures 1. to 8, Sheet I., relate to revolving pistols. Fig. 1. is a
side view of a pistol with my improved trigger or triggers and safety
stop spring applied thereto, and shewing the cock projected on to the
nipple, and the trigger or triggers drawn back. Fig. 2, is a transverse
section of the same in the line a, b, of Fig. 1. Figures 3, and 4, are
longitudinal sections, shewing the parts in different positions. Fig. 3,
shewing the cock raised, and the lifting trigger drawn back; and Fig. 4,
shewing the cock projected on to the nipple, having been liberated by
means of the discharging trigger. Fig. 5. is an end view of the
revolving chamber, with the nipples upon it. Fig. 6, is a longitudinal
section of the same. shewing its elongated socket. Fig. 7, is a trans-
erse vertical section of the frame within which the chamber turns.
hewing the safety stop spring; and Fig. 8, represents another form of
ifting and discharging trigger. In these several Figures the same
etters of reference indicate corresponding parts. u. is the barrel of the

page_text: pistol; b, the ordinary solid frame within which the revolving cham-
ber c, is placed, so as to be capable of turning the required distance on
the pivot or axle d, inserted in the frame b, in the usual manner; e, is
the cock turning on a centre f. and projected on to the nipple by
means of the spring 9, and tail piece h. The lifting trigger is shewn
at i, and the discharging trigger at *. These triggers turn on a
centre. The trigger i, is slotted to hold the trigger **. On the
pivot or centre 1, is fixed the spring pall m, which causes the chamber
to revolve the required distance by acting against a tooth in the
ratchet . on the end of the chamber c, in the usual manner. On this
pivot or centre 1, is also fixed a tail piece or lever o. the upper end of
which serves to raise the cock by pressing against a small recess in the
same, as shewn at Figures 3. and 4. the lower end being acted on by
the discharging trigger . in order to withdraw the upper end from
the said recess. The trigger i. is brought back to the position shewn
in Fig.
after the discharge of the pistol by the pressure of the
spring p.
The safety stop spring is shewn at q, on the inner side of
which is attached a projecting piece r, which projects inwards a sufti-
cient distance (as shewn at Fig. 7.) to prevent the cock from going
forward to the nipple until it is moved outwards into the position
shewn in Fig. 2, by the pall or tail piece m, on the lifting trigger
pressing against the curved end of the projecting piece 1.
The action of this pistol is as follows:-The parts may be brought
into the position shewn at Fig. 3, by drawing back the trigger by the
second finger. The effect of which will be to raise the cock by means
of the tail piece or lifter o. also to turn the chamber c. the required
distance by means of the pall m. and also to remove the safety stop
spring, out of the position shewn at Fig. 7, into that shewn at Fig. 2.
so that it may no longer present an obstacle to the projection of the
cock on to the nipple. The pistol may then be discharged by a slight
pressure of the first or forefinger against the trigger the end of
which will thus be made to act upon the lower end of the tail piece o.
and withdraw its upper end from the recess in the cock as shewn by
dotted lines in Fig. 1. The removal of the pressure of the fingers

page_text: from the trigger or triggers will cause the parts to assume the position
shewn at Fig. 4, ready for another discharge.
The
It will be seen that at Fig. 8, the trigger or triggers are somewhat
different in form from that just described. also that the tail piece or
lifter o, is acted upon at the upper instead of the lower part.
action is otherwise the same as that above described, and I would here
remark that my Invention is not confined to the exact forms thus
represented, provided the action be in its general features the same as
that above described.
I will now describe the elongated socket for the chamber c, which is
represented at s, in Figures 3, and 6. It has a screw formed on it as
shewn, and is prevented from turning by means of a set screw or
pin t, inserted at the hollow part of the chamber c, (see Fig. 6.) This
screwed socket may also be formed with a flange upon it, and may be
used to hold the ratchet n, in the end of this chamber c, without
screws; or the ratchet n, may be put on the flange of the sockets,
and serve as a lock nut to prevent the socket from moving. The
sockets, may also be made without a screw formed upon it, and in
such case metallic washers may be used instead. When the ratchet
n, is used to keep the sockets, in its place, screws must be used with
the ratchet. The frame b, may be countersunk in order to receive the
end of the socket s. By means of this elongated sockets, it will be
een that the chamber c, may be screwed forward or tightened against
he fore part of the frame b, should it be required.
in the line c, d.
I proceed now to describe the second part of my Invention. which
elates to guns intended to be loaded at the breech. Fig. 9, is a side
iew of such gun. Fig. 10. is a transverse section
f Fig. 9, looking towards the stock of the gun. Fig. 11, is a similar
ection in the line e, f, of the same Figure, looking towards the
arrel. Fig. 12, is a longitudinal section, shewing the positions of the
arts at the time when the cock is projected on to the nipple. A. is
e loading chamber, which is kept in its position in the frame B. by
eans of a double acting spring C, pressing against the projection A*,
nd it is made to fit tightly against the end of the barrel by means of

page_text: the bolt and screw D, and E. The chamber A, has on one side of it
alip F, by pressing upon which the chamber may be turned down to
receive the charge; the spring C, also projects the cock. By means of
this spring likewise the pivot or axle G. of the chamber C, is kept in
its position; the end of the said spring, by bearing on one end of the
arm or leaver H, causes a pin or stud on the same to pass into a hole
in the axle G, and thereby hold it. I, is the lifting trigger, and I*,
the discharging trigger, which are shewn in different positions in
Figures 12, and 14; the former Figure shewing the trigger or triggers
before they are drawn back, and the latter shewing the same with the
parts as they would appear when the cock is lifted and ready to be
projected on to the nipple.
The action of this gun is as follows:-The trigger I, is drawn back
into the position shewn by dotted lines in Fig. 12, by which means the
tail piece L, is made to move forward the bent arm or lever M, connected
with the double spring C. In this manner the cock is lifted, and it is
liberated by pressing back the trigger I*, which is thereby withdrawn
from the notch in the bent arm or lever M, turning on a common
centre with the cock, and the cock is projected on to the nipple by the
tension of the spring C. It will be seen that in this case the lifting
trigger only lifts the cock, which may be done by the hand without
such trigger, so that, if preferred, a single trigger, as at 1*, may be
employed alone for this kind of gun. I would also remark, that the
general arrangement of the parts of the gun just described may be
adapted and applied to guns and pistols with revolving chambers. In
the cartridge to be used with this gun the ball is elongated, with a
shoulder extending into the body of the cartridge. At the reverse
end the percussion cap is inserted in such a manner as to obviate the
necessity for breaking off the end before use. Fig. 15, represents in
longitudinal section the same kind of gun, but in which the explosion
is to be produced by forcing a needle or small rod into the cartridge.
It will be seen that the double acting spring C, which holds the
chamber A, in its place is connected so as to act upon the rod to which
the needle N. is attached by means of the bent arm or lever M. which

page_text: in this case is lengthened upwards in order to adapt it for the purpose.
In other respects the action of the gun is the same as that above
described.
With reference to my improvements in the manufacture of gun
barrels, above referred to, I would here remark, that the wire, when
platted, is to be heated to a welding heat, and welded in the usual man-
ner. The wire may be circular or of other form in the cross section.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I would have it understood that
I do not mean or intend to confine myself to the precise forms and
arrangements of the parts shewn and described, as the same may be
varied in some particulars without departing from the general features
of my Invention. I would also here remark, that although I have
described the double trigger or pair of triggers as applied to certain
forms and constructions of fire-arms, yet my Invention is not confined
thereto. And I would further remark, that the gun described under
the second head of my Invention may be combined with the double
trigger or pair of triggers as represented and described, or it may be
combined with a trigger of another form.
I do not, however, claim as of my Invention the several well known
parts of fire-arms which have been necessarily represented and referred
to in order to make the object and essential character of my Invention
evident. But what claim as of my Invention is.
First, the lifting and discharging trigger or triggers. combined with
the safety step spring, and capable of being acted upon in the manner
and with the effect described.
Secondly. the mode described by which the revolving chamber
may be made to fit with the required tightness in the frame which
carries it.
Thirdly, the modified form of trigger or triggers applied to guns to
be loaded at the breech, and the general arrangement and construction
of such guns as described.
Fourthly, the same applied to guns to be fired by means of a
needle.
Fifthly, the use of a cartridge of the kind described.

page_text: And lastly, the manufacture of gun barrels out of spirals of iron.
or iron and steel wire. platted or crossed round a mandril as described.
In witness whereof, I, the said William Tranter, have hereunto
set my hand and seal, this Twenty-sixth day of July, in the
year of our Lord One thousand eight hundred and fifty-three.

page_text: LETTERS PATENT to William Tranter, of Birmingham, in the
County of Warwick, Gun Maker, for the Invention of "CERTAIN
IMPROVEMENTS IN FIRE-ARMS."
Sealed the 23rd March 1858, and dated the 28th January 1858.
PROVISIONAL SPECIFICATION left by the said William Tranter
at the Office of tlie Commissioners of Patents, with his Petition,
on the 28th January 1853.
I, WILLIAM TRANTER, of Birmingham, in the County of Warwick,
Gun Maker, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN FIRE-ARMS" to be as follows:-
My Invention consists, in the first place, in adapting and applying to
pistols and guns a double trigger or two triggers, one portion of the
trigger or one of the triggers being used for raising the cock, and the
other for discharging the piece. And with this trigger or triggers is
combined a safety stop spring to prevent the cock falling, until the catch
is withdrawn by means of the discharging trigger, or discharging
portion of the double trigger. This double trigger or pair of triggers

page_text: may be adapted in various forms to different constructions of fire-arms,
so as to accomplish in each the double purpose of raising the cock, and
at the same time withdrawing the safety stop spring, together with the
discharging of the piece. The trigger or triggers may also have various
forms of guards adapted and applied to them.
My Invention consists, secondly, in elongating the tube or socket of
the revolving chamber in revolving pistols, through which tube or
socket passes the short rod or axis on which the chamber revolves.
The tube or socket may be slightly elongated, and the part of the frame
into which it is required to fit may be countersunk and prepared to
receive it in various ways, so as to increase the facility of applying the
revolving chamber to its position in the frame of the pistol, and prevent
the liability of the chamber to become inconveniently loose in its
position.
My Invention consists, thirdly, in combining the aforesaid double
trigger (019 pair of triggers with the chamber of a gun intended to be
loaded at the breech. In this case a strong spring is used, both to
hold the chamber in its place and to project the cock upon the nipple.
The chamber may be turned round far enough to insert a loaded
cartridge by pressing against a projecting lip and collapsing the spring,
and the cock may be allowed to strike upon the nipple by withdrawing
through the lifting trigger the means by which the projecting force of
the spring upon it was counteracted. In this case, too, the parts may
be retained on "half cock." The cartridge to be used in guns of this
description is one so constructed as to dispense with the necessity of
removing the closed end before placing it in the chamber by closing
the end with a percussion cap.
My Invention consists, fourthly, in combining the double trigger or
pair of triggers with the use of a needle or small rod. to cause the
explosion, in which case the said needle or small rod is projected by
means of a spiral or other spring on the withdrawal of a hent lever
by the lifting trigger.
And my Invention consists, lastly, in making gun barrels out of two
or more spirals of iron or iron and steel wire platted or crossed round a
mandril, the wire so platted being afterwards, heated to a welding heat,

page_text: and welded as in the ordinary manufacture of gun barrels, or it may
be rolled in such state and with a nandril inside between two flat
plates.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Tranter in the Great Seal Patent Office,
on the 28th July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM TRANTER, of Birmingham, in the County of Warwick, Gui
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing late the Twenty-eighth day of January,
in the year of our Lord One thousand eight hundred, and fifty-three,
in the sixteenth year of Her reign, did, for Herself, Her heirs and
Successors, give and grant unto me, the said William Tranter, Her
special license that I, the said William Tranter, my exécutors,
administrators, and assigns, or such others as I, the said William
Tranter, 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 law-
fully might make, use, exercise, and vend, within the United King-
dom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "CERTAIN IMPROVEMENTS IN FIRE-ARMS,"
upon the condition (amongst others) that I, the said William
Tranter, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said In-
vention, 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 William Tranter, do hereby
declare the nature of my said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawings
hereunto annexed, and to the letters and figures marked thereon (that
is to say):
My Invention of "Certain Improvements in Fire-arms" relates, in
the first place, to the kind of fire-arms known as revolving pistols or
pistols with revolving chambers; and consists, first, in adapting and ap-
plying to such fire-arms a double trigger or pair of triggers, combined
with a safety stop spring, by means of which the piece is kept from
being discharged until the spring is moved out of the way of the cock.
which may be done simultaneously with the lifting of the cock and the
turning of the chamber by drawing back the lifting trigger or lifting
portion of the trigger with the second finger. The discharging trigger
may then be moved with facility by the first finger, and the cock pro-
jected on the nipple to discharge the piece. This trigger or triggers
may be used with various forms of guards. The lifting trigger or
lifting portion of the trigger is slotted to hold the discharging trigger or
discharging portion of the trigger. My Invention in relation to this
kind of fire-arms consists, secondly, in elongating the tube or socket
into which the hinder end of the revolving chamber is inserted, in
order that the chamber may be thereby screwed forward when required,
so as to keep the fore end always tightly fitting in the frame.
My Invention relates, in the second place, to guns intended to bu
loaded at the breech, and consists in adapting and applying thereto the
double trigger or pair of triggers, somewhat modified in form as com-
pared with that above referred to, and in the general arrangement of
the parts of the gun, as hereiu-after more particularly described. In
the present instance the trigger is so formed as to be capable of holding.
the gun at "half cock" by means of a tail piece on its end dropping
into a notch or recess in the lower part of the cock, by which
means the front or discharging part of this double trigger acts as a
single trigger. In this case the revolving chamber may be turned
round far enough to insert a loaded cartridge by pressing against a lip
on the chamber, and collapsing the spring by which it is held in its

page_text: place. The cartridge to be used in guns of this description is made so
as to have a percussioni cap inserted in the end opposite to the ball, by
which the necessity for removing its ordinarily closed end may be
obviated.
My Invention relates, in the third place, to guns, in which the
arrangement and action of the revolving chamber and trigger or
triggers are similar to those last referred to, but in which the gun is
discharged by means of a needle or small rod projected by means of the
spring which holds the chamber in its place, or by means of a spiral
spring acting directly upon the rod carrying the needle.
And my Invention refers, lastly, to the mode of manufacturing gun
barrels, and consists in making them out of two or more spirals of iron,
or iron and steel wire platted or crossed round a mandril, the wire so
platted being afterwards heated to a welding heat, and welded as in
the ordinary manufacture of gun barrels.
.
In order, however, that my Invention may be fully understood I will
proceed to describe it more particularly by the aid of the accompanying
Drawings, in which are contained representations of the parts above
referred to..
Figures 1, to 8, Sheet I., relate to revolving pistols. Fig. 1, is a
side view of a pistol with my improved trigger or triggers and safety
stop spring applied thereto, and shewing the cock projected on to the
nipple, and the trigger or triggers drawn back. Fig. 2, is a transverse
section of the same in the line a, b, of Fig. 1. Figures 3, and 4, are
longitudinal sections, shewing the parts in different positions. Fig. 8,
shewing the cock raised, and the lifting trigger drawn back; and Fig. 4,
shewing the cock projected on to the nipple, having been liberated by
means of the discharging trigger. Fig. 5, is an end view of the
revolving chamber, with the nipples upon it. Fig. 6, is a longitudinal
section of the same, shewing its elongated socket. Fig. 7, is a trans-
verse vertical section of the frame within which the chamber turns,
showing the safety stop spring; and Fig. 8, represents another form of
lifting and discharging trigger. In these several Figures the same
letters of reference indicate corresponding parts. a, is the barrel of the

page_text: pistol; b, the ordinary solid frame within which the revolving cham-
ber c, is placed, so as to be capable of turning the required distance on.
the pivot or axle d, inserted in the frame 6, in the usual manner; e, is
the cock turning on a centre f, and projected on to the nipple' by
means of the spring g, and tail piece h. The lifting trigger is shewn
at i, and the discharging trigger at These triggers turn on a
centre k. The trigger i, is slotted to hold the trigger *. On tlie
pivot or centre 1, is fixed the spring pall m, which causes the chamber
to revolve the required distance by acting against a tooth in the
ratchet n, on the end of the chamber c, in the usual manner. On this
pivot or centre 7, is also fixed a tail piece or lever o, the upper end. of
which serves to raise the cock by pressing against a small recess in the
same, as shewn at Figures 3, and 4, the lower end being acted on by
the discharging trigger *, in order to withdraw the upper end from
the said recess. The trigger i, is brought back to the position shewn
in Fig. 4, after the discharge of the pistol by the pressure of the
spring p. The safety stop spring is shewn at q, on the inner side of
which is attached a projecting piece 7, which projects inwards a suffi-
cient distance (as shewn at Fig. 7,) to prevent the cock from going
forward to the nipple until it is moved outwards into the position
shewn in Fig. 2, by the pall or tail piece m, on the lifting trigger
pressing against the curved end of the projecting piece 1.
The action of this pistol is as follows:-The parts may be brought
into the position shewn at Fig. 8, by drawing back the trigger by the
second finger. The effect of which will be to raise the cock by means
of the tail piece or lifter o, also to turn the chamber c, the required
distance by means of the pall m, and also to remove the safety stop
spring, out of the position shewn at Fig. 7, into that shewn at Fig. 2,
so that it may no longer present an obstacle to the projection of the
cock on to the nipple. The pistol may then be discharged by a slight
pressure of the first or forefinger against the trigger *, the end of
which will thus be made to act upon the lower end of the tail piece o,
and withdraw its upper end from the recess in the cock as shewn by
dotted lines in Fig. 1. The removal. of the pressure of the fingers

page_text: from the trigger or triggers will cause the parts to assume the position
shewn at Fig. 4, ready for another discharge.
. It will be seen that at Fig. 8, the trigger or triggers are somewhat
different in form from that just described, also that the tail piece or
lifter o, is acted upon at the upper instead of the lower part. The
action is otherwise the same as that above described, and I would here
remark that my Invention is not confined to the exact forms thus
represented, provided the action be in its general features the same as
that above described.
•
:
I will now describe the elongated socket for the chamber c, whicli is
represented at s,. in Figures 3, and 6. It has a screw formed on it as
shewn, and is prevented from turning by means of a set screw or
pin t, inserted at the hollow part of the chamber c, (see Fig. 6.). This
screwed socket may also be formed with a flange upon it, and may be
ised to hold the ratchet n, in the end of this chamber c, without
screws; or the ratchet n, may be put on the flange of the sockets,
and serve as a lock nut to prevent the socket from moving. The
sockets, may also be made without a screw formed upon it, and in
such case metallic washers may be used instead. When the ratchet
n, is used to keep the sockets, in its place, screws, must be used with,
the ratchet. The frame b, may be countersunk in order to receive the
end of the sockets. By means of this elongated sockets, it will be
seen that the chamber c, may be screwed forward or tightened against
the fore part of the frame b, should it be required.
I proceed now to describe the second part of my Invention,. which
relates to guns intended to be loaded at the breech. Fig. 9, is a side.
view of such gun. Fig. 10, is a transverse section in the line c, d,
of Fig. 9, looking towards the stock of the gun. Fig. 11, is a similar
section in the line e, f, of the same Figure, looking towards the.
barrel. Fig. 12, is a longitudinal section, shewing the positions of the
parts at the time when the cock is projected on to the nipple. A, is
the loading chamber, which is kept in its position in the frame B, by
means of a double acting spring C, pressing against the projection A*,
and it is made to fit tightly against the end of the barrel by means of

page_text: the bolt and screw D, and E. The chamber A, has on one side of it
a lip F, by pressing upon which the chamber may be turned down to
receive the charge; the spring C, also projects the cock. By means of
this spring likewise the pivot or axle C, of the chamber C, is kept in
its position; the end of the said spring, by bearing on one end of the
arm or leaver H, causes a pin or stud on the same to pass into a hole
in the axle G, and thereby hold it. I, is the lifting trigger, and I.**,
the discharging trigger, which are shewn in different positions in
Figures 12, and 14; the former Figure shewing the trigger or triggers
before they are drawn back, and the latter shewing the same with the
parts as they would appear when the cock is lifted and ready to be
projected on to the nipple.
The action of this gun is as follows:-The trigger I, is drawn back
into the position shewn by lotted lines in Fig. 12, by which means the
tail piece L, is made to move forward the bent arm or lever M, connected
with the double spring C. In this manner the cock is lifted, and it is
liberated by pressing back the trigger I, which is thereby withdrawn
from the notch in the bent arm or lever M, turning on a common
centre with the cock, and the cock is projected on to. the nipple by the
tension of the spring C. It will be seen that in this case the lifting
trigger only lifts the cock, which may be done by the hand without
such trigger, so that, if preferred, a single trigger, as at 1*, may be
employed alone for this kind of gun. I would also remark, that the
general arrangement of the parts of the gun just described may be
adapted and applied to guns and pistols with revolving chambers. In:
the cartridge to be used with this gun the ball is elongated, with a
shoulder extending into the body of the cartridge. At the reverse
end the percussion cap is inserted in such a manner as to obviate the
necessity for breaking off the end before use. Fig. 15, represents in
longitudinal section the same kind of gun, but in which the explosion
is to be produced by forcing a needle or small rod into the cartridge.
It will be seen that the double acting spring C, which holds the
chamber A, in its place is connected so as to act upon the rod to which
the needle N, is attached by means of the bent arm or lever M. which

page_text: in this case is lengthened upwards in order to adapt it for the purpose.
In other respects the action of the gun is the same as that above
described.
With reference to my improvements in the manufacture of gun
barrels, above referred to, I would here remark, that the wire, when
platted, is to be heated to a welding heat, and welded in the usual mau-
ner. The wire may be circular or of other form in the cross section.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I would have it understood that
I do not mean or intend to confine myself to the precise forms and
arrangements of the parts shewn and described, as the same may be
varied in some particulars without departing from the general features
of my Invention. I would also here remark, that although I have
described the double trigger or pair of triggers as applied to certain
forms and constructions of fire-arms, yet my Invention is not confined
thereto. And I would further remark, that the gun described under
the second head of my Invention may be combined with the double
trigger or pair of triggers as represented and described, or it may be
combined with a trigger of another form.
I do not, however, claim as of my Invention the several well known
parts of fire-arms which have been necessarily represented and referred
to in order to make the object and essential character of my Invention
evident. But what I claim as of my Juvention is,-
First, the lifting and discharging trigger or triggers, combined with
the safety stop spring, and capable of being acted upon in the manner
and with the effect described.
Secondly, the mode described by which the revolving chamber
may be made to fit with the required tightness in the frame which
carries it.
Thirdly, the modified form of trigger or triggers applied to guns to
be loaded at the breech, and the general arrangement and construction
of such guns as described.
Fourthly, the same applied to guns to be fired by means of a
needle.
Fifthly, the use of a cartridge of the kind described.

page_text: And lastly, the manufacture of gun barrels out of spirals of iron,
or iron and steel wire, platted or crossed round a mandril as described.
In witness whereof, I, the said William Tranter, have hereunto
set my hand and seal, this Twenty-sixth day of July, in the
year of our Lord One thousand eight hundred and fifty-three.
