An Improvement in or in Connection with Hammerless Sporting
Breech Loading Fire-arms.
I, EDGAR HARRISON of 142 New Bond Street in the Parish of St. Georges
Hanover Square in the County of Middlesex, Gun Maker do hereby declare the
nature of this invention to be as follows :—
The object of my invention is to enable the barrels and fore part of hammerless
sporting fire-arms to be placed on and taken off the stock when locks are in uncocked
position, and to reduce friction.
.
To the fore-end or projecting part of the dog, cam, rod or lever I place a piece,
block, cam or arm pivotted thereto so that when the gun is together the piece, cam
arm or block so pivotted takes a bearing on the under side of the barrels in front of
the joint pin. I prefer keeping the said pivotted piece in position by the aid of the
iron of fore part or else by a spring but this is not necessary, by these means and
arrangement both the barrels and the fore part can be taken off or put on to the stock
when the locks are in the uncocked position.
Furthermore I do not require to cut away the back of the front lump so as to put
the barrels into stock when the locks are in uncocked position, nor do I have to lose
any draft of the locks through the dog, cam or lever having to move a certain distance
before commencing to operate on the locks which loss is sometimes occasioned through
the dog, cam or lever protruding in front of the joint pin.
I do not limit myself to placing the dog, cam or lever on the same fulcrum as
barrels, as in some instances the said dog, cam or lever would be better otherwise
situated if it were not for friction, which is reduced to a minimum by the aid of the
pivotted block.
Instead of pivotting the said piece or block to the dog, cam, end or lever and taking
a bearing on the barrels, the said piece may be pivotted to the barrels and take a
bearing on the dog, cam, end or lever.

page_text: My invention further consists in providing means whereby the fore-part can be
placed on, and taken off, the barrels when the locks are in the uncocked position.
This I accomplish by so arranging the dog that when the fore or projecting part
thereof is inserted into the hole or slot in the fore part the latter can be put on to the
barrels when they are in the stock and the locks are in uncocked position. In the
fore part I place a block, piece, cam, or arm pivotted in the fore end iron and above
the apertures therein, this block piece has a nose free to project and pass through the
face of the fore end iron so that when the dog is inserted into the aperture in the fore
end iron the same rests and presses on the piece and thereby fills the aperture in the
fore end iron.
In putting on the fore end the dog forces the block piece in the fore end iron
upwards and thereby protruding the nose through the aperture in the face of the fore
end iron, the completion of the placing on the fore part causes the barrels to force
down the nose of the block piece level with the face of the fore end iron and the base
thereof against the dog.
In the case of the dog, cam, end or lever not working on the same fulcrum as the
barrels I place a roller in the block piece working in the fore-part so as to reduce
friction.
By these means the barrels and fore-part can be put on and taken off whilst the
locks are in the uncocked position.

An Improvement in or in Connection with Hammerless Sporting
Breech-loading Firearms.
I EDGAR HARRISON of 142 New Bond Street in the Parish of St. Georges
Hanover Square in the County of Middlesex Gun Maker do hereby declare the
nature of my invention 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 to enable the barrels and forepart of hammerless
sporting firearms to be placed on, and taken off the stock, when the locks are in the
uncocked position, and at the same time to reduce friction.
In order that my invention may be fully understood and readily carried into effect
I will describe the same with reference to the accompanying drawings.
Figure 1 is a sectional partial side elevation. Figure 2 is a plan with the barrels
removed and Figure 3 is a sectional partial side elevation (showing the barrels open
for cocking) of so much of a hammerless sporting breech loading firearm as will be
necessary to explain my invention.
Figure 4 is a perspective view of cocking lever showing jointed end and Figure 5
is a perspective view showing cross piece for supporting the end of the cocking
lever.
Similar letters of reference refer to like parts in all the Figures.
a
To the fore-end or projecting part of the dog, cam, rod or cocking lever a 1 place
piece, block, cam or arm pivotted thereto so that when the gun is together this piece
cam arm or block b so pivotted takes a bearing on the under side of the barrels as
best seen at Figures 1 and 3 and in front of the joint pin the said joint pin is not
continuous, but is formed to allow of the motion of the levers a; I prefer keeping the
said pivotted piece in position by the end of the cross piece iron c of forepart, shown
separately at Figure 5, or else by a spring but this spring is not necessary, by these
means and arrangement both the barrels d and the foreparte can be taken off or put
on to the stock when the locks are in the uncocked position. Furthermore I do not
require to cut away the back of the front lump so as to put the barrels into stock
when the locks are in uncocked position nor do I have to lose any draft of the locks
or loss of motion of the end of the cocking lever through the said dog, cam or lever
having to move a certain distance before commencing to operate on the locks, which
loss is sometimes occasioned through the dog cam or lever protruding in front of the
joint pin.
I do not limit myself to placing the dog cam or cocking lever a on the same
fulcrum as barrels, as in some instances the said dog, cam or cocking lever a would
be better otherwise situated, and as shown at Figures 1 and 2, if it were not for
friction which is reduced to a minimum by the aid of the pivotted block b.
Instead of pivotting the said piece or block b to the dog, cam, rod, or cocking
lever a, and taking a bearing on the barrels, the said piece b, may be pivotted to the
barrels and take a bearing on the dog, cam, rod or lever a.

page_text: 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. In hammerless breech-loading sporting firearms, the construction and
employment of the piece, block, cam or arm 6 pivotted or jointed to the rod or
cocking lever a whereby the barrels and forepart can be taken off or put on the stock
when the locks are in the uncocked position and friction is reduced, all arranged and
acting substantially as set forth.
Second. In hammerless breech loading sporting firearms the cross piece shown at
Figure 5 constructed arranged and acting substantially as and for the purposes set
forth in combination with the pivotted or jointed arm as claimed in the first claim.
