Improvements in Line Throwing Guns, and Appliances for
the same.
I, REGINALD DEANE, of 56, Upper Mount Street, Dublin, and of the "Princess
Alexandra" Kingstown, in the County of Dublin, Master Mariner, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to the manner in which I construct and arrange
guns for throwing lines and the apparatus and appliances for use with the same;
the object of the invention being to construct a gun capable of being used on board
ship or upon land, which shall be capable of throwing a line with a small explosive
charge employed, and which shall have the line and other apparatus for use upon
or with the gun all self-contained upon or about the mountings or carriage frame
which carries the gun.
In carrying my invention into effect I construct my gun either as a breech or
muzzle loader and I employ any ordinary well known mounting or carriage to
carry the gun whichever may be most suitable for any particular station or vessel
requiring the line firing gun. Similarly I make the gun with a smooth bore or
with rifling to suit the form of projectile and the arrangement of the line coil or
reel which is to be employed.
When constructing my gun with a smooth bore and for muzzle loading, I make
it of steel or other suitable metal with or without hoops and strengthening bands,
and with trunnions formed upon it in the well-known manner at present employed
upon ordinary guns, and I mount the gun by its trunnions in any suitable carriage
so as to take up or prevent damage arising from the recoil strain. I provide
screws or levers with adjustments for enabling the direction of the range of the
projectile to be conveniently altered to suit any particular requirement.
The projectile I make preferably of lead and of a shape to suit the bore of the
gun and with a passage through the centre to permit of its passing freely over a
guiding central line tube, which I mount within the bore of the gun. This central
tube I attach to the breech of the gun by shouldering and screwing, and I form
the outer end of the breech of the gun with a bell-mouthed opening leading to the
bore of the tube. At the muzzle end of the tube I attach my line carrier, which
carrier I make to fit within the bore of the tube and preferably to have a portion
of the line projecting beyond the end of the carrier outside the tube, the portion of
Jine thus projecting being made somewhat larger than the other end of the line
passing freely through the carrier. I make my carrier with a projecting head
collar or shoulder so that when the projectile fired and impelled along the bore
of the gun and over the tube, it will strike against the projecting portion of the
carrier and force it to pass over the enlarged end of the line attachment, and then
to draw the remainder of the line through the tubular guide in the gun. The
object of permitting an enlarged portion of the line attachment to project beyond
the end of the carrier, is to enable the shock or impact of the projectile to be in a
measure taken off the line at starting.
I arrange a length of line behind the gun in the form of a skein, a ball or a roll,
which I mount within a case carried upon the mountings of the gun or which may
be allowed to stand freely behind the gun, in a manner to permit of the line being
readily unwound or withdrawn as the projectile travels forward.

page_text: When mounting my line ball within a casing, I prefer to carry the casing on
arms or brackets projecting from the breech of the gun or from the gun carriage,
the casing having a bell-mouthed opening to permit of an easy and free withdrawal
of the line when the projectile is travelling.
I employ any well-known firing arrangement for detonating my cartridge and I
make the cartridge and charge to be attached to the projectile or to be applied
independently to the bore and firing chamber of the gun as may be desired for
convenience of storage.
I modify the shape and configuration of my carrier, and the form of my
projectile, also the type of the gun mounting to suit any particular requirement.

Improvements in Line Throwing Guns, and Appliances for
the same.
1, REGINALD DEANE, of 56 Upper Mount Street, Dublin, and of "Princess
Alexandra," Kingstown, in the County of Dublin, Master Mariner, 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:-
This invention has reference to the manner in which I construct and arrange
guns for throwing lines and the apparatus and appliances for use with the same;
the object of the invention being to construct a gun capable of being used on board
ship, or upon land, which shall be capable of throwing a line with a small explosive
charge employed, and which shall have the line and other apparatus for use upon
or with the gun all self-contained upon or about the mountings or carriage frame
which carries the gun.
In the accompanying sheet of explanatory drawings-
Figure 1 is a front elevation and Figure 2 a sectional elevation of my
improved gun.
Figure 3 is a plan showing the firing mechanism of the gun, and
Figure 4 is a sectional end elevation of my line holder.
In carrying my invention into effect I construct my gun A either as a breech or
muzzle loader, and I employ any ordinary well known mounting or carriage to
carry the gun whichever may be most suitable for any particular station or vessel
requiring the line firing gun. Similarly I make the gun with a smooth bore or
with rifling to suit the form of projectile and the arrangement of the line coil or
reel C which is to be employed.
When constructing my gun with a smooth bore and for muzzle loading, I make
it of steel or other suitable metal with or without hoops and strengthening bands,
and with trunnions a formed upon it in the well known manner at present employed
upon ordinary guns, and I mount the gun by its trunnions in any suitable carriage
so as to take up or prevent damage arising from the recoil strain. I provide
screws, levers or a handle D with or without adjustments for enabling the direction
of the range of the projectile to be conveniently altered to suit any particular
requirement.
The projectile B I make preferably of lead and of a shape to suit the bore of the
gun and with a passage b through the centre to permit of its passing freely over a
guiding central line tube E which I mount within the bore of the gun. This

page_text: central tube I attach to the breech of the gun by shouldering and screwing, and I
form the outer end of the breech of the gun with a bell mouthed opening A¹
leading to the bore of the tube. Through the muzzle end of the tube I attach my
line carrier F which carrier I make to fit within the bore of the tube; and I some-
times arrange the carrier to project beyond the end of the tube, the portion of the
carrier thus projecting being made somewhat larger than the other end. I make
my carrier with a projecting head, collar or shoulder F¹ so that when the projectile
is fired and impelled along the bore of the gun and over the tube E, it will strike
against the projecting portion F¹ of the carrier and force it to pass over the
enlarged or corded end H and then impel the carrier forward and thereby draw
the remainder of the line G through the tubular guide E in the gun. The object
of permitting a projecting collar or shoulder and an enlarged coiled rope end H
to project beyond the end of the carrier F is to enable the shock or impact of the
projectile to be in a measure taken off the line at starting.
I
arrange a length of line behind the gun in the form of a skein, a ball, or a
roll C which I mount within a case K carried upon the mountings or special tail
bars L of the gun, or which may be allowed to stand freely behind the gun, in a
manner to permit of the line G being readily unwound or withdrawn as the
projectile travels forward.
When mounting my line ball within a casing I prefer to carry the casing on
arms or brackets L L projecting from the breech of the gun or from the gun
carriage, the casing having a bell mouthed opening K¹ to permit of an easy and
free withdrawal of the line when the projectile is travelling.
I employ any well known friction tube or other firing arrangement such as M M'
for detonating my cartridge N, and I make the cartridge and charge to be attached
to the projectile B or to be applied independently to the bore and firing chamber
of the gun as may be desired for couvenience of storage.
I form the head O of my line carrier so that it may carry a signal pilot or blue
light and 1 attach a firing line P' to a friction tube R placed within the head so
that when desired a light may be displayed to indicate the position of the line
when fired; the end of the firing line I make fast to any part of the gun before
firing.
The line GI attach conveniently to a metal shoe G¹, and the rope stopper knot
or head F¹ I construct with the ends of the strands enlarged and passed over a
central length of steel wire rope H, to increase the friction and support the knot
when in position ready for firing.
I form the projecting end H of the carrier of such a diameter and length that
the knotted stopper head F¹ may pass along over it when fired, aud I make the
bead of a shape to prevent the carrier head passing off the projecting end when
it is carried forward by the impact of the shot.
To take up the shock of firing and to prevent the person firing the gun from
receiving any injury, I prefer to employ a spiral spring d in combination with my
handle D as shown in Figure 2.
I modify the shape and configuration of my carrier and the form of my projectile
also the type of the gun mounting to suit any particular requirement.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is-
1. The improvements in line throwing and firing guns and in the method of
carrying the line substantially as and for the purposes herein before described and
as illustrated in the accompanying drawings.
2. In a line throwing gun the arrangement of a reel or coil of line placed behind
the gun and having one end passing through a central tube and then connected to
a carrier substantially as hereinbefore described and as illustrated in the
accompanying drawings.

page_text: 3. In a line throwing gun, the arrangement of a central guiding tube with a
cartridge and projectile free to pass over the tube substantially as and for the
purposes hereinbefore described and as illustrated in the accompanying drawings.
