Complete Specification Left 17th May 1899-Accepted. 30th Aug. 1899
CHRISTIAN FREDERICK ADOLPH BELL, Marine Engineer, 48, All Saints Street,
Hull, do hereby declare the nature of this invention to be as follows:-
This valve is screwed into the outside of the pump barrel, like an ordinary
one, for the purpose of emitting, (with every down stroke of plunger) the air,
accumulating, during its working, the valve has no guide within the orifice, in
the shape of wings or the like, but is a simple metallic disc (leather faced) for
closing orifice, on the opposite side of disc is fixed a spindle, for working inside
a small tube forming the guide for valve, the working of valve being surrounded
by a small cylinder or casing, with outlet at bottom for waste water, on the top
of this cylinder or casing is screwed a cover, to the inside of which is attached
the small tube forming the guide for valve and spindle; also on the top of the
"leather faced valve is fixed a light metallic disc, nearly fitting the cylinder
or casing, for keeping the water more direct on the outlet, thus preventing it
splashing about in the cylinder or casing, which, owing to the bilge water being
dirty and greasy, would soon impede the valve from working properly, the object
is to have a way without obstruction for the dirty bilge water through orifice of
valve, to ensure it's continual working.

Improvements in Pet Valves for Bilge Pumps and the like.
I, CHRISTIAN FREDRICK ADOLPH BELL, 48, All Saints Street, Hull, Marine
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 invention relates to bilge and other pumps and the like, and is a method
of allowing the air which accumulates in the said pumps to escape, on the down
stroke of the pump ram, or upstroke of bucket, or with up and down stroke, if
pump be double acting, thus assisting in forming a vacuum in the pump, thereby
causing the pump to be more effective, than otherwise would be the case.
The invention is illustrated by the accompanying sectional elevation and plan,
of the various parts described in Figures I & II. The same letters and numeral,
indicate the part in each view. A is the body of the valve, a cylinder of brass

page_text: or any other suitable material. B is a brass guard or deflector, screwed on the
spindle D. Spindle, working freely in the guide H. C is a small nut, screwed
on the valve spindle, and used, to regulate "lift" of valve E, and also for securing
in position the deflector B. To keep the brass valve perfectly air tight, it is faced
with leather I, or any other flexible material. F is an elbow, one part of which is
screwed into the pump barrel, and the other end into the bottom of the cylinder A,
projecting through the same about 1/8" to form the valve scat. G is a drain pipe,
at the bottom of the cylinder A, discharging air & water, passing from under the
valve into the bilges again. The cover of the cylinder A is secured on the top
of cylinder by being threaded on the inside of rim, the cylinder on the outside, the
guide H, being fixed on the inside part of cover, the cover having a hole through
it in line with guide tube H, for allowing the spindle D, to work through the
same about " above the cover J, the latter having a milled edge,-the whole of
it representing a valve, enclosed within a cylinder guided with a spindle from the
top, through cover, with elbow tube for inlet, and outlet tube at the bottom of
cylinder.
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 valve for the aforesaid purpose, working on top of the seat, being guided
from outside of seat instead of from the inside (as ordinarily is the case with
valves for a similar purpose).
2) The ready manner, in which it may be examined or cleaned when necessary
without spanner or the like, or without risk of loosing small parts belonging to
the same, in simply unscrewing cover, and being able to remove it and valve
together.
3) The being able to regard its actions by guide rod working through cylinder
cover, (which is not the case in ordinary pet valves.
