ROBERT LOW Engineer Albert Machine Works 146 Overgate Dundee 1 do hereby
declare the nature of this invention to be as follows :-
The gun can be smooth bore or rifled or with one or more slots.
The projectile can be made of wood or any hard material such as Iron Steel or
Brass the line is fixed at end which is put foremost in the gun, passes over the end
& leads all along the projectile in a slot made for the purpose of holding it freely.
The Line can be made entirely of hemp flax or cotton but it may be advisable in
heavy guns to attach a few feet of wire rope for passing into gun.
Wad to be made of wood or other hard material wood as a preference, this piece of
wood to vary in length according to size of gun. A piece of asbestos American
fibre or any other good substance for withstanding fire to be nailed on each end of
this piece of wood.
The wood to be an easy fit for the gun barrel but the asbestos or other material to
be a tight fit.

page_text: ROBERT LOW, Engineer, Albert Machine Works 146 Overgate, Dundee, do
hereby declare the nature of my invention for IMPROVEMENTS IN GUN PROJECTILES
AND WADS FOR THROWING LINES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
The gun can be smooth bore, or rifled or with one or more slots.
The projectile can be made of wood or any hard material such as iron steel or brass,
the line is fixed at end which is put foremost into the gun and passing over that end
leads alongside the projectile in a slot made for the purpose of holding it freely.
The line can be made entirely of hemp, flax or cotton.
The wad to be made of vulcanized fibre and it must be a tight fit in the gun.
DESCRIPTION OF DRAWINGS.
Fig. 1. represents a side view of the gun, with projectile in position ready for being
fired off.
The line A. which is attached to the rear end of the projectile; as will be more
particularly described hereafter, may be coiled alongside of gun in any convenient
manner, so that it may uncoil as freely as possible when projectile is fired off.
To the front of projectile is fixed a holder B. for carrying a light, which is
ignited by means of a friction fuze actuated by cord C. when projectile is leaving
the gun.
To take up the recoil of the gun I fix a brake D. on each side of the gun carriage
as shewn.
a. is a crossbar fixed to underside of gun carriage, b is a bolt passing through a
hole at end of a. and also through D. c. is a rubber washer or steel spring, which
acts between block D. and the nut of bolt b. and keeps block D pressing upon
the wheels.
Figs. 2. and 3. represents a plan and section of the vulcanized fibre wad.
Fig. 4. is a longitudinal section through the centre of wooden projectile; (which I
find is preferable to make of lignum vitae or box wood) showing how line is attached
to rear end. It also shows how the line is passed round the rear end and into the
longitudinal slot F. A knot G is formed on the end of the line to prevent it slipping
through the hole H.
Fig. 5 is a section at E. E.
Figs. 6, 7, 8, 9 and 10. are views of the iron, steel or brass projectile.
Figs. 6 and 7. represent projectile with end unscrewed ready for receiving line.
Fig. 8. is a rear end view of the projectile.
Fig. 9. is a longitudinal section through the centre showing end screwed into
position with line attached.
Fig. 10. represents a section of same at I. I.

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
(1) A Gun Projectile made of wood or other hard material, substantially as
described with reference to Figs. 4 and 5.
(2) A Gun Projectile made of iron or other hard material, substantially as
described with reference to Figs. 6, 7, 8, 9 and 10.
(3) A wad of vulcanized fibre.
