Year: 1874

page_text: LETTERS PATENT to George Jeffries, of the Oity and County of
Norwich, Gun Maker, for the Invention of "IMPROVEMENTS IN DOUBLE-
BARRELLED SPORTING BREECH-LOADING FIRE-ARMS."
PROVISIONAL SPECIFICATION left by the said George Jeffries at the
Office of the Commissioners of Patents, with his Petition, on the
8th October 1874.
•
I, GEORGE JEFFRIES, of the City and County of Norwich, Gun Maker,
do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN DOUBLE-BARRELLED SPORTING BREECH-LOADING FIRE-ARMS,” to be as
follows:-
-
My Invention consists in fixing or forming on the breech end of
double sporting barrels what is commonly known in the trade as a lump
on each barrel for attaching the barrels to the action, instead of one
lump fixed in the central line between barrels as heretofore, thus forming
a double double-bolt snap action-

page_text: I take a pair of double breech-loading gun barrels and braze on the
under side of the breech ends thereof next the action a lump of steel,
say an inch and a quarter broad and three inches long. I then cut a slot
in the centre of the lump from end to end thereof, say three-eighths of
an inch wide, and down to the flat of the barrels, thus forming two
separate and distinct lumps, one on cach barrel; this done, they are filed
down to a convenient form and inserted in corresponding slots formed in
the body of the action; they are afterwards hinged in the usual manner,
and each lump has a separate double bolt fitted; by this means I obtain
greater strength and durability than heretofore.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Jeffries in the Great Seal Patent Office on
the 8th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
JEFFRIES, of the Oity and County of Norwich, Gun Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of October, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said George Jeffries, Her special
licence that I, the said George Jeffries, my executors, administrators,
and assigns, or such others as I, the said George Jeffries, 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, uso, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
DOUBLE-BARRELLED SPORTING BREECH-LOADING FIRE-ARMS," upon the condition
(amongst others) that I, the said George Jeffries, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and scals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the samo was to bo
performed, and cause the same to be filed in the Great Seal Patent.

of the said Letters Patent.
NOW KNOW YE, that I, the said George Jeffries, do hereby declare⚫
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings
and to the letters of reference marked thereon, that is to say :—
My Invention consists in fixing or forming on the brecch end of
double sporting barrels what is commonly known in the trade as a lump
on each barrel for attaching the barrels to the action, instead of one
lump fixed in the central line between barrels as heretofore, thus forming
a double double-bolt snap action.
I take a pair of double breech-loading gun barrels and braze on the
under side of the breech ends thereof next the action a lump of steel,
say an inch and a quarter broad and three inches long. I then cut a
slot in the centre of the lump from end to end thereof, say threc-eighths
of an inch wide and down to the flat of the barrels, thus forming two
separate and distinct lumps, one on each barrel; this done, they are filed
down to a convenient form and inserted in corresponding slots formed in
the body of the action; they are afterwards hinged in the usual manner,
and each lump has a separate double bolt fitted; by this means I obtain
greater strength and durability than heretofore.
Figure 1 of the accompanying Drawings is a plan, and Figure 2 a
side elevation of the breech end of a double-barrelled sporting brecchi-
3 loading fire-arm with a lump of steel brazed on to the same according
to my Invention. Figure 3 shows in plan, Figure 4 in side clevation,
and Figure 5 in end view, the same portion of a gun barrel with the
lump of stcel filed down so as to form two separate and distinct lumps,
one on each barrel.
Figure 6 is a view in plan of the body of the action into which the
lumps are inserted.
Figure 7 is a view in longitudinal section of the breech portion of a
gun complete, the full lines showing the lumps inserted in the body of
action, and the dotted lines showing the lumps raised and out of the
; body of the action. A, A, aro the lumps on the under side of the

page_text: barrel; B, B, are the slots into which the lumps are inserted. In
Figures 3, 4, 5, and 7 I show two lumps, one on each barrel; but in
Figure 8, which is a view in plan of the under side of breech end of
barrel, and Figure 9, which is an end view of same, I show at the rear
portion thereof only a single lump between barrels as heretofore, but
at the forward portion I show so much of a double lump as is sufficient
to form a hinged joint on each barrel.
Figure 10 is a view in plan of the body of the action into which the
Jumps aro inserted. C is the bolt used for locking the barrels when the
gun is closed; a detached view of this bolt is shown in plan at Fig. 11.
An arrangement for keeping this bolt back when the barrels are open is
as follows:-D is a pin shown separately at Fig. 12, having a slotted
head a, through which the arm 6 of the guard lever c is passed; the head
of the arm 6 also takes into the double bolt C, as shown at Fig. 7. The
pin D passes through the middle bar d in the body of the action in a slot
formed in it for its reception. The outer end of pin D enters an
aperture in the fore end joint ƒ when the barrels are down or shut home.
It will be thus scen that the pin and bolt move together when the lever c
is operated. Thus, supposing the barrels to be open, then the fore end of
the pin rests on the hollow of the fore end joint f; by this means the
double bolt O is held and kept back clear of the slot of the breech, so
that as the barrels are closed up the lumps A thereon are free to enter
the slots B of the body without any obstruction whatever; the barrels
being closed the bolt C and pin D respectively simultaneously enter the
slots in lump and the slot in the hinged joint; the barrels are then
locked. To unlock the barrel, depress the lever c, when the pin D and
the bolt O simultaneously leave their respective slots, and the barrels are
ready for charging. I do not limit myself to the employment of this
particular kind of pin D holding the bolt C back while the barrels
are open; I have however found it a convenient way of effecting this
purpose. Other means might, however, be devised, and I lay no claim to
this particular plan described, except when it is used in combination as
hereafter claimed with the lumps on barrels as aforesaid.
Having now described the nature of my said Invention and in what
manner the same is to be performed, I declare that I claim,―
First. The fixing or forming on the breech end of double sporting
barrels of a lump on each barrel, substantially in manner and for the

page_text: purposes described with reference to Figs. 1, 2, 3, 4, 5, 6, and 7 of the
accompanying Drawings.
Second. The fixing or forming on the breech ond of double sporting
barrels of a lump on each barrel, substantially as described with
reference to Figs. 8, 9, and 10 of the accompanying Drawings.
Third. The construction and employment of breech-loading double-
barrelled sporting fire-arms having lumps on the barrel, and slots in the
body in combination with a pin for holding back the locking bolts, all
substantially as herein-before described and illustrated in the accom-
panying Drawings, together with any mere modification or modifications
thereof.
thereof.
In witness whercof I, the said George Jeffries, have hereunto set
my hand and seal, this Sixth day of April, in the year of our Lord
One thousand eight hundred and seventy-five.

NOW KNOW YE, that I, the said George Jeffries, do hereby declare
the nature of my said Invention, and in what manner the same is to be

following statement, reference being had to the accompanying Drawings
and to the letters of reference marked thereon, that is to say :—
My Invention consists in fixing or forming on the breech end of
double sporting barrels what is commonly known in the trade as a lump
10 on each barrel for attaching the barrels to the action, instead of one
lump fixed in the central line between barrels as heretofore, thus forming
a double double-bolt snap action.
I take a pair of double breech-loading gun barrels and braze on the

separate and distinct lumps, one on each barrel; this done, they are filed
down to a convenient form and inserted in corresponding slots formed in
20 the body of the action; they are afterwards hinged in the usual manner,
and each lump has a separate double bolt fitted; by this means I obtain
greater strength and durability than heretofore.
Figure 1 of the accompanying Drawings is a plan, and Figure 2 a
side elevation of the breech end of a double-barrelled sporting breecli-
25 loading fire-arm with a lump of steel brazed on to the same according

to my Invention. Figure 3 shows in plan, Figure 4 in side clevation,
and Figure 5 in end view, the same portion of a gun barrel with the
lump of steel filed down so as to form two separate and distinct lumps,
one on each barrel.
Figure 6 is a view in plan of the body of the action into which the
lumps are inserted.
Figure 7 is a view in longitudinal section of the breech portion of a
gun complete, the full lines showing the lumps inserted in the body of
action, and the dotted lines showing the lumps raised and out of the
35 body of the action. A, A, are the lumps on the under side of the

Figures 3, 4, 5, and 7 I show two lumps, one on each barrel; but in
Figure 8, which is a view in plan of the under side of breech end of
barrel, and Figure 9, which is an end view of same, I show at the rear
portion thereof only a single lump hetween barrels as heretofore,

.
Figure 10 is a view in plan of the body of the action into which the
lumps are inserted. O is the bolt used for locking the barrels when the
gun is closed; a detached view of this bolt is shown in plan at Fig. 11.
An arrangement for keeping this bolt back when the barrels are open is
as follows: - -D is a pin shown separately at Fig. 12, having a slotted
head a, through which the arm 6 of the guard lever c is passed; the head
of the arm b also takes into the double bolt C, as shown at Fig. 7. The
pin D passes through the middle bar d in the body of the action in a slot
formed in it for its reception. The outer end of pin D enters an
aperture in the fore end joint f when the barrels are down or shut home.
It will be thus seen that the pin and bolt move together when the lever c
is operated. Thus, supposing the barrels to be open, then the fore end of
the pin rests on the hollow of the fore end joint f; by this means the
double bolt C is held and kept back clear of the slot of the breech, so
that as the barrels are closed up the lumps A thereon are free to enter
the slots B of the body without any obstruction whatever; the barrels
being closed the bolt C and pin D respectively simultaneously enter the
slots in lump and the slot in the hinged joint; the barrels are then
locked. To unlock the barrel, depress the lever c, when the pin D and
the bolt C simultaneously leave their respective slots, and the barrels are
ready for charging. I do not limit myself to the employment of this
particular kind of pin D holding the bolt C back while the barrels
are open; I have however found it a convenient way of effecting this
purpose. Other means might, however, be devised, and I lay no claim to
this particular plan described, except when it is used in combination as
hereafter claimed with the lumps on barrels as aforesaid.
