SPECIFICATION.
I CHRISTOPHER GEORGE BONEHILL of Belmont Row, Birmingham in the County
of Warwick, Gun Manufacturer do hereby declare the nature of said Invention
for "IMPROVEMENTS IN DOUBLE BARRELLED SMALL ARMS" to be as follows:—
The object of my Invention is the putting together of double barrels by having
a solid all-through lump on their breech ends; that is to say, I roll iron or steel, of
the figure of the cross-section of the top rib and the prolonged rib, the web passing
between the barrels; the flats coming under the barrels, and the double lump
underneath the flats-The said web combined with the under-flats, havo on each
side a concavity suitable for the reception of each end of the barrels-The end of
each barrel is sectioned to meet the figure of the combined parts before described;
that is, the ends of the barrels are of less diameter on their inner sides, or
terminating in shoulders diagonally; the top shoulders on the junctions of the cut-
away parts lie nearly flush and engage with the sides of the top rib. The lower
shoulder of the cut-away part of the barrels engages with the terminations of the
flats on which the ends of the barrels seat themselves.
By means of these seats, the fitting and connecting of the barrels to the combined
rib, centre web, flats and lumps, is much facilitated; and when the barrels are
brazed in the accurately fitted concavities as before described, great strength and
security is thereby obtained.

page_text: I CHRISTOPHER GEORGE BONEHILI. of Belmont Row, Birmingham, in the County
of Warwick, Gun Manufacturer do hereby declare the nature of said Invention
for "IMPROVEMENTS IN DOUBLE BARRELLED SMALL ARMS" and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :--
The object of my Invention is the putting or connecting together of double
barrels, by having a solid all through lump at their breech ends; that is to say,
I roll or otherwise fashion iron or steel to the figure of the cross section of the
top rib and the prolonged rib, the thin web passing between the barrel, the flats
coming under the barrels, and the double lump underneath the flats of an ordinary
drop down arm-The said web combined with the under flats, have on each side
a concavity suitable for the reception or seating of the breech end of each of the
barrels The end of each barrel is sectioned or reduced in thickness on one side to
meet the figure of the combined parts on each side of the thin web as described,
that is the outside breech ends of the barrels, are reduced, or are of less diameter
on their inner sides and terminating in shoulders diagonally-The top shoulders
nt the junctions of the cut away parts of the barrels lie nearly flush, and engage
with a part of the sides of the top rib; while the lower shoulders of the cut-away
part of the barrels engage with and fit upon the terminations of the flats on which
the cut away ends of the barrels scat themselves-By means of these seats, the
fitting, connecting or putting together of the barrels to the combined rib and
prolonged rib, division web, under flats and lumps is much facilitated, and when
the barrels are brazed in the accurately fitted concavities as before described, grent
strength and security is thereby obtained.
Having now described the nature of my said Invention, I will now proceed to
describo with reference to the accompanying Drawings, the manner in which the
same is to be performed.
Figure 1 represents in back elevation, Figure 2 in plan-Figure 3 a side view of
the breech ends of a pair of barrels put or connected together according to my
Invention Figure 4 represents an end view of the parts separately before they are
placed in their respective positions Figure 1; and Figure 5 is a back end view of
the all through lump-Figure 6 is a plan of the said all through lump showing
the top rib and the prolonged rib for fastening down barrels to the break off-
Figure 7 is a side elevation of Figure 6, and Figure 8 is a plan of the underside of
the said all through lump-Figure 9 shows an edge view of one of the barrels
Figures 1 and 2; and Figure 10 is a plan of the cut away part or underside of one
of the said barrels so as to better exhibit the shoulders which respectively fit or
engage with, the top rib and the terminations of the Ants.
a. a. are the breech ends of a pair of barrels which are fitted at their breech ends
into the concavities b³, b. on either side the thin division web b-c, is tho upper or
top rib having the prolonged rib c on its front or forward end d. d, are the under-
flats upon which the breech ends of the barrels are seated and rest and e. c. are tho
underlumps which fasten down the barrels to the body of the arm-a². a. are the
respective top shoulders on each barrel, which engage on each side of the top rib,
while a, a, are the lower shoulders engaging with the extremities of the under-
flats d. d-a. a'— are the cut-away parts of the barrels.
In fitting or putting together double barrels according to my improvements,
I roll or fashion iron, steel or other suitable metal, of the figure in cross section to
the shape of the combined top rib c and the prolonged ribe, the thin division

page_text: web b, and flats d. d. for coming under the barrels, and also the double lump e
underneath the said flats as best seen in Figures 4 and 5-The said division web b
has a concavity b. b. on either side thereof suitable for the reception of the
cut-away or reduced parts of the barrels; that is, the concavities forin seats into
which the ends of the barrels are fitted-The combination all through lump
described, is completed by cutting or planing processes common to the fashioning
and shaping of metals.
The breech ends of the barrels a. a. are reduced or cut away in diameter on their
inner side a. at which terininate in shoulders a², a³, so that the top shoulders a². aª,
of each barrel engages on the respective sides of the top rib -The bottom
shoulders a³. a³, engage with and fit upon the extremities of the flats d. d. while the
cut away parts a. a seat themselves within the concavities ò. b. and on the parts
Figure 4 being put together, and the breech ends of the barrels brazed within the
accurately fitting concavities as described, the putting together of barrels is much
facilitate, and considerable cost saved incidental in the production of the barrels
small arms of the kind represented in the said Figures 1, 2 and 3, by the above
improvements great strength, durability and security is also thereby obtained.
+
An ordinary rib is placed within the space f between the barrels and brazed
thereto at the same time that the all through lump is brazed as described-The
dotted lines represent the position which the rib takes.
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 :-
First The improvements in the putting or connecting together of double barrels,
hereinbefore described and illustrated in in the accompanying Drawing; that is to
say, fitting reduced or cut-away parts of the breech ends of double barrels into
acurately fitting concavities formed out of a solid all-through lump; the parts being
arranged and put together substantially as described and illustrated.
Secondly Making in one piece a breech end solid all-through lump, hereinbefore
described and illustrated in the accompanying Drawing; that is to say, making
the breech end top rib, the prolonged rib, the thin web within the barrels, the flats
coming under the barrels, and the double lump underneath the flats in one piece,
produced by rolling or fashioning iron, steel or other metal, to the desired section,
which is afterwards shaped and finished as hereinbefore described and set forth.
Thirdly The reduced or cut-away breecl: ends marked at, with the shoulders a². a³,
for fitting in the concavities on either side the web of the all-through lump for
the purpose as described and illustrated.
