IMPROVEMENTS IN AND CONNECTED WITH LINE-THROWING GUNS OR FIRE ARMS
Year: 1885

page_text: I, DAVID RUSSELL DAWSON, of 57 Meadowside, Dundee, in the County of Forfar,
North Britain, Merchant, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN AND CONNECTED WITH LINE-THROWING GUNS OR FIRE ARMS,"
to be as follows that is to say:
:-
My said Invention relates to line-throwing guns of the kind described in the
Specification of Evans and Low's patent N° 3460 of 1881; and consists principally
in constructing the projectile so as to carry an increased quantity of line or cord,
the improvements also assisting the attainment of an increased range and greater
accuracy of flight.
My improved projectile consists of a tubular part to enter the barrel of the gun
and corresponding to the canister of the original line-throwing gun carrying the
line in a cop form, but an enlarged hollow head is formed on the front end of the
tubular part. This hollow head is of a pear like shape and is divided at its widest
zone so that it can be opened to insert a ball of cord or twine which is joined to
the end of the cord or twine forming the cop in the tubular part. The front part
of the head is connected to the other part by a bayonet joint or in any other con-
venient way. With this improved construction a considerably increased quantity
of cord or twine can be carried; and it will generally be unnecessary to have the
back end of the cord or twine passed through a central tube in the gun barrel to
be connected to a further quantity at the rear of the gun, as in the original gun.
A solid rod can therefore be substituted for the tube the ond of the cord or twine
of the projectile being fixed to the front end of such rod. In some cases the ball
of cord or twine in the hollow head of the projectile may be sufficient without
there being a further quantity in cop form in the tubular part, and this tubular
part may be left empty or a light wooden tube may be substituted for it.

I, DAVID RUSSELL DAWSON, of 57 Meadowside, Dundee, in the County of Forfar,
North Britain, Merchant, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement that is to say :—
My said Invention relates to line-throwing guns of the kind described in the
Specification of Evans and Low's Patent N° 3460 of 1881; and consists principally
in constructing the projectile so as to carry an increased quantity of line or cord,
the improvements also assisting the attainment of an increased range and greater
directness and accuracy of flight.
My improved projectile consists of a tubular part to enter the barrel of the gun
and corresponding to the canister of the original line-throwing gun carrying the
line in a cop form, but an enlarged hollow head. is formed on the front end of the
tubular part, such hollow head not only containing an additional quantity of line
or cord, but also causing the projectile to fly with diminished oscillation or tendency
to inversion. This hollow head is of a pear-like shape and is divided at its widest
part so that it can be opened to insert a cop formed with an enlarged part or head,
or to insert a ball of cord or twine which is joined to the end of the cord or twine
forming the cop in the tubular part. The front part or the head is connected to
the other part by a bayonet joint or in any other convenient way. With this
improved construction a considerably increased quantity of cord or twine can be
carried; and it will generally be unnecessary to have the back end of the cord or
twine passed through a central tube in the gun barrel to be connected to a further
quantity at the rear of the gun, as in the original gun. A solid rod can therefore
be substituted for the tube the end of the cord or twine of the projectile being
fixed to the front end of such rod. In some cases the ball of cord or twine in the
hollow head of the projectile may be sufficient without there being a further
quantity in cop form in the tubular part, and this tubular part may be left empty
or a light wooden tube may be substituted for it. :
On the accompanying sheet of explanatory drawings, figure, 1, is a side elevation
of a line-throwing gun as loaded with my improved line-carrying projectile.
Figure, 2, shows the gun in section. Figures, 3, and 4, are an elevation and section
of a larger example of my improved projectile suitable for cannons and ships' guns.
The projectile is made with a tubular part, 10, which is like the original
projectile and contains a line or cord, 11, coiled within it in a cop-like form so as
to easily uncoil from it as the projectile proceeds on its flight. This tubular part
is inserted into the barrel, 12, of the gun the construction of which may be as
before. On the front end of the tubular part, 10, of the projectile there is forined
or fixed a hollow head, 13, 14, of a pear-like or other suitable form, and this head
is divided at its widest zone so that it can be opened to insert the cop, 11, with its
enlarged head, 15. The front part, 14, of the hollow head is connected to the
other part by bayonet joints, or in any other convenient way. In the example
shown in figures, 3, and 4, the outer part, 14, of the head, is fixed to the other
part, 13, by a couple of screws.

page_text: With this improved construction a considerably increased quantity of cord or
twine can be carried; and it will generally be unnecessary to have the back end of
the cord or twine passed through the central tube, 16, in the gun barrel, 12, to be
connected to a further quantity at the rear of the gun, as in the original gun,
although this may be done when thought desirable. A solid rod may be substituted
for the tube, 16, and the end of the cord or twine of the projectile may be fixed to
the front end of such rod. In some cases a ball, 15, of cord or twine in the hollow
head, 13, 14, of the projectile may be sufficient, without there being a further
quantity in cop form in the tubular part, 10, and this tubular part may be left
empty, or a light wooden tube may be substituted for it.
kind to be fired from the shoulder;
my Invention is however applicable with various kinds and sizes of guns or
fire arms.
The gun shown in figures, 1, and 2, is of
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:-
In line-throwing guns of the kind in which the line or a large portion of it is
carried by and delivered from the projectile, the making of the projectile with a
tubular part to enter the gun barrel combined with an enlarged hollow head
constructed to receive an enlarged part of a cop or a ball or coil of line or cord in
addition to or instead of the cop or coil in the smaller tubular part substantially as
herein before described.
