PROVISIONAL SPECIFICATION.
Improved Means for Controlling the Flow of Fluids Under Pressure.
I, DANIEL HURST, of 9, Grange Road, Pendleton, Manchester, Sanitary
Engineer, do hereby declare the nature of this invention to be as follows:-
My said invention relates to improved means for regulating controlling or
baffling the flow of fluids under pressure.
According to my said invention I insert in a suitable container formed in or
attached to a pipe valve or other conduit for the fluid a quantity of small detached
particles such as shot or granulated metal or other suitable material. A cage
basket or preferably a rolled up ball of wire is inserted in the conduit to retain
the small particles while permitting the passage of the fluid. According to the
quantity and size of the particles the initial fluid pressure is more or less baffled
or diminished. In the same sized container the pressure may be varied by vary-
ing the size of the particles.
I therefore where varying conditions of initial pressure have to be met pro-
vide means such as screwed plugs caps or the like for removing the material
from the container and substituting finer or coarser particles.
In one form of my said invention I combine with the container an air vessel
to minimise concussion when for instance a cock or tap is closed and the supply
out off.
Although applicable to fluids generally my said invention possesses particular
advantages when applied to controlling the flow of water supplied under great
pressure by preventing excessive splashing rush or noise and minimising the
impact or shock of the water against valves and other fittings when the supply
is suddenly turned on.
Improved Means for Controlling the Flow of Fluids Under Pressure.
I, DANIEL HURST, of 100B, Queen Victoria Street, London, E.C., late of
9, Grange Road, Pendleton, Manchester, Sanitary 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:-
My said invention relates to improved means for regulating controlling or
baffling the flow of fluids under pressure.

page_text: According to my said invention I insert in a suitable container formed in or
attached to a pipe valve or other conduit for the fluid a quantity of small detached
particles such as shot or granulated metal or other suitable material. A cage
basket or preferably a rolled up ball of wire is inserted in the conduit to retain
the small particles while permitting the passage of the fluid. According to the
quantity and size of the particles the initial Huid pressure is more or less baffled
or diminished. I prefer to use lead shot since such is conveniently obtainable
of any desired size. In the same sized container the pressure may be varied
by varying the size of the particles.
I therefore where varying conditions of initial pressure have to be met pro-
vide means such as screwed plugs caps or the like for removing the material
from the container and substituting finer or coarser particles.
The accompanying drawings show sectional elevations of two ways of applying
my said invention.
According to Figure 1 the particles P are contained in an expansion or swell a
formed in or secured to the pipe b. They are kept in position by plugs e formed
of wire rolled up in a coil or ball.
According to Figure 2 the shot or other particles are enclosed in a cage or
shell of wire c¹ contained in a conical part of the tube at a junction so as to
permit of the shot being readily removed and replaced. In this construction
the ends of the lead pipe 6¹¹ are coned and flanged outwards so as to be gripped
between the faces of two nipples or flanged rings ff and to form a receptacle
for the shot. The flange of the ring fis externally screwed to fit a coupling
nut 9. the other end of which takes behind the flange of the ring f. Flats or
the like are provided on the coupling nut g to enable it to be turned for the
purpose of drawing the rings f f together and thus making a tight joint.
Although applicable to fluids generally my said invention possesses particular
advantages when applied to controlling the flow of water supplied under great
pressure by preventing excessive splashing rush or noise and minimising the
impact or shock of the water against valves and other fittings when the supply
is suddenly turned on.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what
I claim is:
1. The herein before described means for baffling the flow of fluid in a pipe
substantially as set forth.
2. The combination with a fluid conveying pipe of an internal baffle of shot
or the like small particles held in position by plugs substantially as set forth
and shown with reference to Figure 1 of the accompanying drawings.
3. The combination with a fluid conveying pipe of an internal cage or con-
tainer containing shot or the like small particles and means for holding the
same in position while giving ready access thereto substantially as set forth and
shown with reference to Figure 2 of the accompanying drawings.
