page_text: I ANDREW NOBLE lato Captain in the Royal Artillery of Jesmonddine House
Newcastle upon Tyne Manufacturing Engineer do hereby declare the nature of
this invention to be as follows:-
This invention has for its object a machine for supplying a jet of water at
a high pressure to wash out heavy guns. The machine comprises a hydraulic
cylinder with piston and rod, working a force pump. These are contained in a
tank holding the water to be used in washing the gun.
The purpose is
(1.) To avoid using to waste the fresh water circulating in the hydraulic system
fitted in the ship, as this water at times cannot be easily replaced.
(2.) To avoid having recourse to the fire main system as it is inconvenient to
have to do so.
.
(3.) To enable a definite quantity of water to be used for each washing of the
gun, to guard against the tendency to insufficiently wash the gun in
the hurry of action.
At the top of the machine is the hydraulic cylinder in which is the piston and
rod. This cylinder is supplied with hydraulic pressure from a slide välve attached
to it. The slide valve is worked through its spindle by the lever fitted with a
balance weight so that the slide valve is brought automatically into the position
which admits the pressure water to the underside of the piston causing the piston
to rise.
The piston rod is directly attached to the force pump plunger and this conse-
quently is automatically lifted to draw a charge of water into the force pump by
a passage in which is an inlet valve. The machine thus when left at rest charges
itself and remains charged ready for use.
To use the machine the hand lever and balance weight are lifted, this moves the
slide valve into the position for admitting pressure to the top side of the piston.
The piston is thus forced down and acting through the piston rod it forces the ram
into the pump and the water is consequently ejected past an outlet valve and
through a long flexible pipe into the gun."

The tank which can be made as large as possible or can be connected with
another tank as the circumstance of the case may best admit, is filled with sea or
other water, a sufficient quantity being therein contained to wash the gun out
as many times as it is considered will be necessary between the opportunities of
refilling the tanks.

I ANDREW NOBLE late Captain in the Royal Artillery of Jesmonddine House
Newcastle-upon-Tyne Manufacturing Engineer 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 for its object a machine for supplying a jet of water at
a high pressure to wash out heavy guns. The machine comprises a hydraulic
cylinder with piston and rod working a force pump. These are contained in a
tank holding the water to be used in washing the gun.
The purpose is
=
(1) To avoid using to waste the fresh water circulating in the hydraulic system
fitted in the ship, as this water at times cannot be easily replaced.
(2) To avoid having recourse to the fire main system as it is inconvenient to
have to do so.
(3) To enable a definite quantity of water to be used for each washing of the
gun to guard against the tendency to insufficiently wash the gun in the
hurry of action.
At the top of the machine is an hydraulic cylinder in which is a piston and rod.
This cylinder is supplied with hydraulic pressure from a slide valve attached to it.
The slide valve is worked through its spindle by a lever fitted with a balance
weight so that the slide valve is brought automatically into the position which
admits the pressure water to the underside of the piston causing the piston to rise.
The piston rod is directly attached to a force pump plunger and this conse-
quently is automatically lifted to draw a charge of water into the force pump by
a passage in which is an inlet valve. The machine thus when left at rest charges
itself and remains charged ready for use.
To use the machine the hand lever and balance weight are lifted, this moves the
slide valve, into the position for admitting pressure to the top side of the piston.
The piston is thus forced down and acting through the piston rod it forces the ram
into the pump and the water is consequently ejected past an outlet valve and
through a long flexible pipe into the gun.
The tank which can be made as large as possible or can be connected with
another tank as the circumstances of the case may best admit, is filled with sea or
other water, a sufficient quantity being therein contained to wash the gun out
as many times as it is considered will be necessary between the opportunities of
refilling the tanks.
In order that my said invention may be fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation of apparatus for washing guns arranged in
eccordance with me invention

page_text: D is the hydraulic cylinder and E is the rod of the piston working within it.
F is the slide valve admitting water under pressure from any suitable source to
one side or the other of the piston. G is a weighted hand lever which when left
alone so places the valve that water may enter beneath the piston and pass away
from the space above. When the band lever is lifted these conditions are reversed.
H is a plunger fixed on to the piston rod. J is a pump cylinder which the plunger
enters when the hydraulic piston descends. K is the tank containing a supply of
sea water; the cylinder J is filled from it through a suction valve shown at J'
when the plunger H rises. J' is an aperture in the side of the cylinder J at which
an outlet valve is fitted and a suitable flexible pipe applied.
Having now particularly described and ascertained the nature of my said
invention and in what manner the sanie is to be performed I declare that what
I claim is :-
1. The combination in apparatus for washing guns of an hydraulic cylinder,
valve and hand lever and a force pump in direct connection with the piston in
the hydraulic cylinder substantially as described.
2. Apparatus for washing guns substantially as described and shown by the
annexed drawings.
