Year: 1834

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
CHARLES LOUIS STANISLAS, Baron HEURTELOUP, of Holles Street,
Cavendish Square, in the County of Middlesex, send greeting.
WHEREAS His present most Excellent Majesty King William
the Fourth, by His Letters Patent under the Great Seal of Great
Britain, bearing date at Westminster, the Twenty-Second day of
May, in the Fourth year of His reign, did, for himself, His heirs and
successors, give and grant unto me the said Charles Louis Stanislas
Baron Heurteloup, His especial license, that I, the said Charles
Lewis Stanislas, Baron Heurteloup, my exors, adñiors, and assigns, or
such others as I, the said Charles Louis Stanislas, Baron Heurteloup,
my exors, adfors, or assigns, should at any time agree with and no
others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick upon
Tweed, my Invention of "IMPROVEMENTS IN CERTAIN PARTS OF CERTAIN
DESCRIPTIONS OF FIRE-ARMS," in which said Letters Patent is con-
tained a proviso, that I, the said Charles Louis Stanislas, Baron
Heurteloup, shall cause a particular description of the nature

page_text: of my
said Invention, and in what manner the same is to be per-
formed, to be inrolled in His said Majesty's High Court of Chancery,
within six calender months next and immediately after the date
of the said in part recited Letters Patent, as in and by the same,
reference being hereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the
said Charles Louis Stanislas, Baron Heurteloup, do hereby declare
the nature of my said Invention to consist,-
First, in the adaptation or fitting up of the stock of a musket
or other the like fire-arm to receive, and of the lock plate and hammer
to bring forward to the touch hole, a small pipe or tube made of soft
metal or other substance, which may be easily divided, containing
the priming, which priming is detonating powder, and the end of
which said pipe is cut off or otherwise divided or separated from
the remainder, and the powder in the end so cut off or separated,
detonated or exploded by the falling or blow of the said hammer
when the fire-arm is discharged, in manner hereinafter inore par-
ticularly explained.
And, secondly, in so arranging and forming the hut plug and
breech of a double or single barrelled gun or other such fire-arm,
that the barrel may be detached from the break off, and the hut
released from its hold by the action of a lever, in such manner as
to enable the cartridge to be put in at the breech end of the barrel,
after which it is rammed tightly to its final position, by the mere act
of replacing or re-adjusting the barrel to the breech by means of the
same lever by which it was detached.
And in further compliance with the said proviso I, the said
Charles Louis Stanislas, Baron Heurteloup, do hereby describe the
manner in which my said Invention is to be performed by the
following statement thereof, reference being had to the Drawings
annexed, and to the Figures and letters marked thereon, that is to
say:
DESCRIPTION OF THE DRAWINGS.
In the Drawing marked A, Figure 1, is a side view of the but end
of the stock of the lock, and of part of the barrel of an ordinary

page_text: fowling piece. The but end of the stock is bored in a line from
A, to B, at which latter point the cavity for the lock begins so as
to receive what I call the priming tube, which is a long small tube
or pipe made of soft metal, and filled with detonating powder;
the part colored pink here represents the priming tube in the bore
extending through its whole length into and along the cavity made,
for the lock, till it reaches the guide nipple C, through which
it passes, and it is thus directed to the touch hole D. It will
be seen that just below the touch hole E, is a ledge or shelf at E, on
which the end of the priming tube rests; and I will now proceed
to describe, first the hammer itself, and then its action on the
priming tube. First, then, as to the hammer itself, it is made forked
at the end, so as to bestride the guide nipple C, when it falls.
The dark blue line l', is a steel blade or knife extending over the
fork the full width of the head of the hammer, and G, is a piece of
steel which I call the striking piece, and is screwed on to the head
of the hammer by the screw H, which keeps itself and the blade F,
firmly to its place. When the hammer is let down by pulling the
trigger, it describes in falling the arc shown by the dotted lines, the
fork at the end bestrides the guide nipple while the steel blade
F, cuts a small piece off the end of the priming tube, which piece
remains on the ledge or shelf E, which shelf I call the anvil, where
the striking picce G, comes in contact with it, and by the blow
causes the powder in it to detonate, thus communicating fire to the
touch hole, while the steel blade F, covers the hole at the end of
the guide nipple, and thus, interposing itself between the end
cut off of the priming tube and what remains in the guide
nipple, effectually prevents the fire communicating to the remainder
of the priming. In order more accurately to describe the con-
struction of the head or upper part of the hammer, I have shown
its several parts separately at Figures 2, 3, 4, 5, and 6. Figure 2,
is a plan of the hammer head, shewing the end 1, forked so as
to enable it to bestride the guide nipple; Figure 3, is a side view
of the steel blade or knife which cuts the priming tube; Figure 4,
is a plan of the same, shewing an open slot J, at its hinder end,

page_text: for the purpose of adjustment on the hammer head; Figure 5,
is a plan of the striking piece, the hole for the screw being oblong
also for the purpose of adjustment, and Figure 6, is a side view of
the same; and it may be as well here to state that similar letters
and colors are used to denote similar parts in all the Figures of this
Drawing. Now, having described that the proper portion of
priming for each discharge is obtained by cutting off a piece from
the end of the priming tube, it follows of necessity that some means
must be provided of advancing a fresh portion of the priming tube
under the knife after each discharge of the fire arın, and this I
effect on the drawing back of the hamniner to half cock, by means of
a small contrivance connected with that movement, which I shall now
proceed to describe:-Figure 7, is a view of the inside of the hammer
or cock; K, is a small spring catch let into a recess cut for it, but
projecting at the end K a little way out from it, as shown in
Figure 8, which is a front view of the cock or hammer; Figure 9,
is a plan; and Figure 10, a side view of the said spring K, shown
separately. It is this spring K, projecting from the inside of the
cock, which, when the cock is drawn back to half cock, acts upon
the mechanism; which causes the priming tube to advance the
required distance to bring it under the knife after each discharge,
and which mechanism is clearly shown in Figure 11, which is a
plan or top view of the lock; L, is the square, or, as in this case, the
hexagon arm, on which the cock is fitted, the cock being removed
here in order not to confuse the Figure. M, is a ratchet wheel of
six teeth, having a milled boss beneath, as shown at Figure 12;
this ratchet wheel turns on a centre N, firmly fixed to the solid
piece O, of the lock plate, the milled boss being let into the solid
piece; P, is a spring paul or catch to secure the ratchet wheel
from moving, except in the direction of the arrow, and that only
when required; Q, is another spring, with a friction roller R, at
one end of it; the piece O, of the lock plate it will be seen is bored
to receive the priming tube, which it will be observed passes
through it, between the milled boss of the ratchet wheel and
the friction roller R; the object of the spring Q, and roller R,

page_text: being to press the soft metal priming tube against the milled boss
of the ratchet wheel sufficiently to indent it slightly, and thus give
the milled boss sufficient hold of the tube to force it forward when
the ratchet wheel is turned round. In order to describe the action of
this mechanism, the hammer must be supposed to be down after a
discharge, when the spring catch K, which is on the inside of the
cock, will take into one of the teeth of the ratchet wheel M. On
drawing the cock back again the spring K, will force the ratchet
wheel round one tooth or notch, and the priming tube will be
advanced in proportion; by this time the hammer will have
arrived at half cock, and the spring K, will have disengaged itself
from the tooth of the ratchet wheel, so that the cock may afterwards
be drawn back to full cock without any further interference with
the priming mechanism; Figure 13, is a view of the interior of the
lock showing the aperture at 7, into the bore made for the priming
tube, through which aperture the friction roller is admitted to
press upon the priming tube; Figure 14, is an end view of Figure
13; Figure 15, is a separate view or plan of the spring Q, and
friction roller R; Figure, 16, is a side view of the same; Figure 17,
is a separate view or plan of the spring paul or catch
and
Figure 18, is a side view of the same; Figure 19, is a side view of
the breech, touch hole, anvil, and hut of the fire-arin, and
Figure 20, is an end view of the same; Figure 21, is a side view
of the break off of the fire-arın shewing the guide nipple, and Figure
22, is an end view of the same; Figure 23, is a separate and side
view of the priming tube, and Figure 24, is an end view of the same;
Figure 25, is a plan of that part of Figure 1, which is immediately
over it.
Having now described the first part of my said Invention, which
relates to the adaptation of the stock and lock to receive, and the
application thereto of the priming tube aforesaid, I will proceed
to the description of the second part of my said Invention, which
is more particularly confined to improved means of loading at
the breech, and which, for the more easy understanding of the
Figures, I have described without the priming mechanism, though

page_text: I would wish it to be understood, that the said priming mechanism
is equally capable of being adapted to fire-arms made on the
principle of those I am now about to describe, as of those I
have already described, but for the purpose of this part of the
specification, I have only availed myself of so much of the former
part as relates to the soft metal priming tube filled with
detonating powder, which I describe as the priming used in cach
case.
The second part of my said Invention is particularly described
by the Figures on the Drawing marked 13. Figure 1, is a side view
of the barrel of a double barrelled gun, which is the fire-arm I have
selected in this case to illustrate my Invention. Instead of having
a hut formed on the plug at the but end of the barrel, as is usual,
I have two huts A, and B, formed on to the solid central piece between
the two barrels; C, is a round stud or pin, the use of which will be
explained hereafter; and D, is a mere steadying or guide pin, the po-
sition of which in the stock will be shown by other Figures; the hut
B, it will be seen has an oblong hole E, in it, and it may be as well
here to state, that I accomplish the loading at the breech by tilting
up the but end of the barrel, and depressing the muzzle end, while
the barrel turns on a fulcrum, introduced through the oblong hole
E. Figure 2, is a but end view of Figure 1; F, F, being the nipples
against which the hammer strikes to detonate or explode the priming,
and G, G, are two grooves to admit a short piece of aforesaid
priming tube. Figure 3, is a side view, partly in section, of the
barrels placed in the stock; 1, is the fulcrum pin.
my
The steadying
pin D, is in a mortice cut for it, and it will be observed that
the inortice and the two cavities cut for the huts A, and 13, are all
longer than the respective parts which are to occupy them, the
reason of which is, that in order to tilt up the breech, for the p
purpose
of loading the fire-arm, I am obliged to separate the barrels from
the break off and plugs by advancing them along the stock, and the
extra size of the mortice and cavities, before-mentioned, is to allow
for that action, which is obtained by means of the mechanism
colored green, and which will be hereafter explained. Figure 4, re-

page_text: presents a side view of the barrels when in the position required for
loading; it will be seen that the barrels have turned on the pin or
fulcrum H, the guide or steadying pin D, has been raised partly out
of its mortice, and the hut A, has been completely raised out of the
cavity cut in the stock for its reception, and the barrels have been
advanced along the stock, for it will be seen that if the but end, as
shown in this Figure, were to be depressed, it would form the arc
described by the dotted lines, and would not come in contact with the
break off till acted upon by the mechanism colored green, by which
alone the barrels can be drawn back to the break off when required,
as will be hereafter explained. It will be seen that there is a pro-
jecting piece Í, forming part of the break off, and it is scarcely ne
cessary to observe that there is one to each barrel. These projecting
pieces are, in fact, the plugs being formed in one piece with the break
off, instead of being in one piece with the huts as usual. These
plugs enter the barrels when the barrels are drawn back to the break
off, and their object is two fold. First, to completely stop the breech
end of the barrels, and secondly, to ram the cartridge tight; this
latter object is generally attained by the ramrod, applied from the
muzzle end of the gun, but as the chamber which holds the charge
or cartridge is somewhat longer than the barrel, it stands to reason,
if the cartridge J, is put into this chamber at the breech end, and
is of the full length of the chamber, and is then drawn back against
the plug I, the forcing of the plug into the chamber must ram the
cartridge, the advance of which is resisted by the narrowing of the
barrel at K. Figure 5, is a view of the barrels with their but ends
brought down again upon the stock, but still separated from the
break off, the huts A, and B, and the guide pin D, occupying the
muzzle ends of their respective cavities. Before I proceed to
describe the mechanisın colored green, for advancing the barrels
from and drawing them back to the break off, I may as well describe
the sort of cartridge which is required for this improved fire-arm
(that is to say): The cartridge should be made with a cup of wood
or lead at the end next the plug I, bored to receive a short piece of my
said priming tube as shown by Figures 6, 7, 8, and 9. Figure 6, is

page_text: a side view of a cartridge complete, with the fuse or priming tube.
Figure 7, is a section of the cup and tube shown separately.
Figure 8, is a front view of the cup and tube looking into the
cavity of the cup and tube, and Figure 9, is a side view of the cup
and tube.
I will now proceed to describe the mechanism colored green, for
advancing and drawing back the barrels on the stock. It is a lever
movement, and I have here shown the trigger guard used for that
lever, though it may perhaps be thought preferable that the guard
should be fixed as usual, and a separate lever applied for that
purpose; as this, however, would be adding to the mechanisın, I
prefer to use the guard itself as the lever. Figure 10, is a plan of
that part of the stock in which the breech ends of the barrels rest,
and slide forward and backward. L, is the cavity for what I call
the fulcrum hut B. M, is the mortice for the guide pin D, and N, is
the cavity of the hinder hut A. 1, is a plug shown separately at
Figures 11, 12, 13, 14, 15, and 16; the top part of this plug is
shown in plan in Figure 10, which I am now describing, and is an
excentric, having a cavity Q, cut in it to receive the pin C. When
the plug is in this position, the excentric projection, which is at e,
enters a cavity cut for it in the hut A, as shown in Figures 1,
and 3. One end of the guard R, is fastened to a square on the
lower extremity of the plug P, and forms a lever, by which it is
turned.
When the guard is pushed out from the stock, as shown by
dotted lines at S, the plug P, turns and draws forward the barrels
by means of the pin C, being in the cavity Q. When the guard
arrives at right angles with the stock, as shown by red lines at T, the
cavity Q, has arrived at its greatest point of action, and the barrels
will be sufficiently advanced from the break off to allow the muzzles
being depressed, as shown in Figure 4, (that is to say) they will be
in the position shown at Figure 5. When the muzzles have been
depressed, the cartridges put in, and the barrels again brought to
the position shown in Figure 5, and the guard gradually moved back
into its proper place, the excentric boss at e, acts upon the hut A,

page_text: and drives the barrels back until the cavity Q, again begins to act
upon the pin C, and draws the barrels close up. to the break off, as
before and as shown in Figure 3. The metal piece containing the
cavities and mortice L, M, N, may either be made in one piece with
the break-off, as here shown, or separately. In order to give a more
perfect idea of the plug P, I have given separate views of its
various parts. Figures 11, and 12, are side elevations, and Figure 13,
is a plan of the said plug. Figure 14, is a side view, and Figure 15,
a plan of a screw nut, which keeps the plug from rising in the hole
bored for it through the stock, and Figure 16, is a side elevation of
the plug and nut and the end of the guard, all screwed up to their
respective places. Figure 17, is a plan, and Figure 18, a transverse
section of a fulcrum pin, which passes through the oblong hole in the
fulcrum hut B, and on which the barrels turn. Figure 19, is a plan
of the breech end of the barrels, shewing the nipples and part of
the break off. Now, whereas I claim as my Invention, First, The
improvements in that part of a fire-arm commonly called the lock,
hereinbefore described, whereby I am enabled to present a succession
of priming in a tube or case to the touch hole, and cut or break off
or otherwise separate as much as is necessary for each discharge
from the remainder of the same, and explode the part so separated,
for the purpose of the discharge, on an anvil or shelf contrived for
the purpose, without igniting any other portion of it, and in
the Drawing annexed I have described a manner of accomplishing
all these objects without any other action being required of the
operator, but the ordinary one of bringing the cock, after it has
been let down for the discharge, back to half cock.
And secondly, The Improvements or new arrangements of those
parts of a musket, pistol, carbine, fowling piece, or other the like
fire-arm, commonly called the break off, hut plug breech, and barrel,
hereinbefore described, whereby I am enabled to advance the
barrel from the plug, tilt it up from the stock, load at the breech,
bring the barrel down upon the stock again, and ram the cartridge,
by bringing the barrel back again to the plug with the aid only of

page_text: a single lever, which may be the trigger guard itself, if required, as
hereinbefore shown.
And such my Invention being, to the best of my knowledge and
belief, entirely new and never before used within that part of His
said Majesty's United Kingdom of Great Britain and Ireland called
England, His said dominion of Wales, or town of Berwick upon
Tweed, I do hereby declare this to be my Specification of the same,
and that I do verily believe this my said Specification doth comply
in all respects, fully and without reserve or disguise, with the pro-
viso in the said hereinbefore in part recited Letters Patent contained,
wherefore I do hereby claim to maintain exclusive right and privi-
lege to my said Invention.
In witness whereof, I, the the said Charles Louis Stanislas,
Baron Heurteloup, have hereunto set my hand and seal this
Twenty-first day of November, in the year of our Lord,
One thousand eight hundred and thirty-four.

describe the sort of cartridge which is required for this improved
fire-arm (that is to say), the cartridge should be made with a

the cup and tube. 1 will now proceed to describe the mechanism,
"colored green, for advancing and drawing back the barrels on the
stock.
It is a lever movement, and I have here shown the trigger
guard used for that lever, though it may perhaps be thought pre-
"ferable that the guard should be fixed as usual, and a separate lever

"separately at Figures 11, 12, 13, 14, 15, and 16. The top part of
"this plug is shown in plan in Figure 10, which I am now describing,

4 lines at S, the plug P, turns and draws forward the barrels by
of the pin C, being in the cavity Q. When the guard arrives
"at right angles with the stock, as shown by red lines at T, the cavity
Q, has arrived at its greatest point of action, and the barrels will be
sufficiently advanced from the break off to allow the muzzles being

position shown at Figure 5. When the muzzles have been depressed,
"the cartridges put in, and the barrels again brought to the position
