PROVISIONAL SPECIFICATION.
Improvements in Mechanism for Controlling and Regulating the
Discharge of Liquids from Tanks.
I, WILLIAM GEORGE STRYPE, of 115 Grafton Street, Dublin, Ireland, Civil
Engineer, do hereby declare the nature of this invention to be as follows, that is
to say:-
My said invention has for its object to provide improved mechanism for
controlling and regulating the discharge of liquids from tanks, and which is such
as to secure efficient scouring out action on matters deposited from the waters stored
in the tanks, an important application of the invention being for works dealing with
sewage waters.
The tank to which the improved mechanism is to be applied has the bottom
formed into a series of parallel bays or broad angular gutters leading to a
transverse end space or gutter in which is placed the discharge penstock with its
valve and overflow pipe. At the discharge euds of the bays or gutters, sluices are
arranged with appliances for raising them, the operation being effected by means
of a horizontal shaft extending over the series of sluices. The sluice raising
appliances are acted on by cams on the horizontal shaft these cams being arranged
to open only some of the sluices at one time, every third or fourth one for example,
in order that the discharging water may have its flow and scouring action con-
centrated on the parts leading to the open sluices. The horizontal shaft has cams
to act on all the sluices, but these are disposed so as to act on separate sets. in
succession. The horizontal cam shaft may be turned in any suitable manner; in
a convenient arrangement, however, it is turned by worm-and-worm wheel gearing
from a shaft turned by hand or otherwise, and which also by worm-and-wormwheel
gearing actuates the gearing for opening the penstock valve. The gearing is
arranged so that the cain shaft for opening the sluices makes a fourth or other
suitable part of a turn for every opening of the penstock valve, different sluices
being opened at each such part of turn. A transverse gutter connects the further
ends of the angular gutters so that water passes into those of the latter which are
open from the others.

Improvements in Mechanism for Controlling and Regulating the
Discharge of Liquids from Tanks.
I, WILLIAM GEORGE STRYPE, of 115, Grafton Street, Dublin, Ireland, Civil
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, that is to say :-
My said invention has for its object to provide improved mechanism for
controlling and regulating the discharge of liquids from tanks, and which is
such as to secure efficient scouring out action on matters deposited from the waters

with sewage waters.
At the discharge ends of the bays or broad angular gutters formed in the tank
to which the improved mechanism is to be applied, sluices are arranged with
appliances for raising them, the operation being effected by means of a horizontal
sbaft extending over the sluices. The sluice-raising appliances are acted on by
cams on the horizontal shaft, disposed so as to act on separate sets of sluices in
succession. The horizontal shaft is turned by worm-and-wormwheel gearing from
a shaft turned by hand or otherwise, and which also by worm-and-worm wheel gearing
actuates the gearing for opening the penstock valve.
And in order that my said invention and the manner of performing the same may
Le properly understood I hereunto append two sheets of explanatory drawings,
to be hereinafter referred to, and showing my improved mechanism for controlling
and regulating the discharge of liquids from tanks.
Figures, 1, and, 2, on Sheet, 1, of the drawings are vertical sections, as at right
angles to each other, of part of a sewage tank, as provided with the improved
mechanism, Figure, 3, being a horizontal section of the same.
Figure, 4, on Sheet, 2, is a plan, and Figure, 5, is a sectional elevation of part
of the improved mechanism.
Figures, 6, and 7, are respectively a plan and sectional elevation of a detail,
hereinafter described.
In these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
The tank, A, to which the improved mechanism is applied has the bottom formed
into a series of parallel bays or broad angular gutters, B, leading to a transverse
end space or gutter, C, at the middle of which is placed the discharge penstock, D,
with its valve, E, and overflow pipe, F. At the discharge ends of the bays or
gutters, B, sluices, G, are arranged with appliances for raising them, the operation
being effected by means of a horizontal shaft, J, extending over the series of
sluices. The sluice-raising appliances, for each sluice, G, consist of a pair of
vertical rods, K, the bottom ends of which are fixed to the sluice, and the top ends
have fixed to them fork pieces, L, the jaws of which embrace the horizontal
shaft, J. The fork pieces, L, are made with guide rods, M, at the top, and are
fitted with anti-friction rollers, N, which are acted on by cams, P, on the horizontal
sha't, J, these cams being arranged to open only some of the sluices, G, at one
time, every third or fourth one for example, in order that the discharging water
may have its flow and scouring action concentrated on the parts leading to the open
sluices. The horizontal shaft has cams, P, to act on all the sluices, G, but these
are disposed around the shaft in a manner to act on separate sets in succession.
The horizontal can shaft, J. may be turned in any suitable way; in a convenient
arrangement which is shown in the drawings, however, a handwheel, Q, carried in
suitable bearings, R, is employed by means of bevil pinions, S, and T, to drive a
vertical shaft, U, formed with a worm, U 1, which gears with a worm wheel, J 1,
fast on the cam shaft, J. The vertical shalt, U, is also formed with another
worm, V, which gears with a wormwheel, V 1, fast on a small borizontal shaft, V 2,
having on its end a crank, V.3, which, through a connecting rod, V 4, a slide
block, V 5, a guide trunk, V 6, and a rod, V 7, acts on the penstock valve, E.
The gearing is arranged so that the cam shaft, J, for opening the sluices, G,
makes a fourth or other suitable part of a turn for every opening of the penstock
valve, E, different sluices being opened at each such part of a turn. A transverse
gutter, W, connects the further ends of the angular gutters, B, so that water passes
into those of the latter which are open, from the others.
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:
The construction, arrangement, and combination of parts constituting the
