PROVISIONAL SPECIFICATION.
Improvements in Water Syphon Cisterns and all other Cisterns.
ALEXANDER Ross, Plumber and Brassfounder, Elgin, in the County of
Morayshire, North Britain, do hereby declare the nature of this invention to be
as follows:
:-
Improvements in water syphon cisterns and all other cisterns.
This invention relates to improvements in the construction of a
pipe" for use in drowning the noise in water cisterns and water closets.
silent drown
In carrying out my invention I make in any kind of metal a tube to be fixed to
a ball cock or water pipe, and at the down end of tube I fix an inner bell to the
tube with holes, then an outer bell, allowing the water to go down the tube, then
up the inner bell, and through the holes to outer bell passing silently down the
outer bell to cistern.
The "silent drown pipe" is an invention for a double purpose viz. to prevent
noise and vibration from ball cock in cistern as the water when it passes in at the
tube rises in an inner tube and passes slowly through four small perforations from
inner tube or bell to an outer tube or bell, then descending silently through the
latter, thus obviating any vibration of the ball cock and drowning any noise caused
by the high pressure of water rushing into cistern.

COMPLETE SPECIFICATION.
Improvements in Water Syphon Cisterns and all other Cisterns.
I, ALEXANDER Ross, of Greyfriers Street, Elgin, in the County of Morayshire,
North Britain, Plumber and Brassfounder, 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 relates to improvements in the construction of a "silent down
pipe" for use in drowning the noise in water cisterns and water closets.
In carrying out my invention I make in any kind of metal a tube to be fixed to
a ball cock or water pipe and at the down end of tube I fix an inner bell to the
tube with holes; then an outer bell allowing the water to go down the tube, then
up the inner bell and through the holes to outer bell and thence passing silently
down the outer bell to the cistern.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters
marked thereon.
Figure 1 is a longitudinal section of cistern with the silent down pipe fitted to
the ball cock, part of which is in elevation and part in section.
Figure 2 is an enlarged section of the apparatus. The supply pipe is broken off.
Arrows indicate the flow of the water in its passage through the silent down pipe.
Figure 3 is a section on line A B of Figure 2.
Figure 4 is a section on line C D of Figure 2.
The letters cc, indicate the outer bell of the invention and bb, the inner bell,
and a is the tube.
The invention is for a double purpose viz. :-to prevent noise and vibration
from a ball cock in cistern. As the water when it passes in at a rises at bb, and
flows slowly through four small openings d, (three openings are described in Figs. 1,
D

page_text: and 2, one of which is indicated by dotted lines), from inner bell to outer bell cc,
afterwards descending silently through the outer bell a c, thus obviating any
vibration of the ball cock and drowning any noise caused by the high pressure of
water rushing into cistern.
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 combination of the apparatus fixed to a ball cock or water supply pipe,
to prevent noise in water cisterns, substantially as herein described and according
to the accompanying drawing.
2. The combination of the apparatus constructed of any metallic or other
substance, or shape, substantially as berein described and for the purpose
specified.
