County of Lanark, Engineer do hereby declare the nature of my said Invention
for
"AN
IMPROVED DRAINING OFF VALVE FOR SETTLING TANKS to be as
follows:-
""
This Invention consists of an improved construction of valve for draining off
water or other liquid from settling tanks such as are used for separating starch
from water.
The improved draining off valve consists of a tubular valve box or tube formed
with a flange by which it is bolted against the outlet orifice in the side and near
the bottom of the tank, and whose outer end is fitted with a curved plate or door
carried by arms on each side pivotted near the flange of the valve box. The
bearing faces of the valve box end and of the cover or door form an arc of a circlo
and are truly faced so that the door may freely slide on the end of the valve box
and prevent the outflow of liquid excepting over the upper edge when the door is
opened, a screw adjustinent being also provided to tighten up the valve as the
bearing faces wear. The valve or door is operated by means of a screw spindle
and hand lever connected to the arms which secure the valve to its pivots. In
using the valve the starch or other material being allowed to settle in the tank, the
valve is lowered gradually and the water or liquor runs off through the valve box
and over the top of the door until the door reaches the level of the solid deposit.
by which tipe the water is all drained off.

page_text: I BERNHARD HEINRICH REMMERS of 189 Saint Vincent Street Glasgow in the
County of Lanark Engineer do hereby declare the nature of my said Invention for
"AN IMPROVED DRAINING OFF VALVE FOR SETTLING TANKS" and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :-
This invention consists of an improved construction of valve for draining off
water or other liquid from settling tanks such as are used for separating starch
from water.
The improved draining off valve which is illustrated in side and end elevation
as applied to a tank in figures 1 and 2 of the accompanying drawings consists of a
tubular valve box or tube A formed with a flange by which it is bolted against the
outlet orifice in the side and near the bottom of the tank B, and whose outer end
is fitted with a curved plate or door C carried by arms d, d on each side pivotted
at d' near the Bange of the valve box.
The bearing faces of the valve box end and of the cover or door C form an arc
of a circle from the oscillating centres d¹ on which the radius bars d oscillate, and
are truly faced so that the door may freely slide on the end of the valve box and
prevent the outflow of liquid excepting over the upper edge when the door is
opened, a screw adjustment such as the screws and nuts d² connecting the arins d
to the door C, being also provided to tighten up the valve as the bearing faces
wear, The valve or door C is opened by means of a screw spindle and hand lever
or similar device (not shown in the drawings) connected by a jointed link or
frame F, F, to the arms d which secure the valve to its pivots.
In using the valve the starch or other material having been allowed to settle in
the tank B the valve is lowered gradually and the water or liquor runs off through
the valve box A and over the top of the door C until the door reaches the level
of the solid deposit by which time the water is all drained off. The valve may be
raised upwards to permit of the free outflow of liquid from the tank.
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 The combination of parts forming the improved draining off valve herein
described and illustrated.
2 In a draining off valve the arrangement of sliding door C secured adjustably
on its seat by the pivotted arms d, d, substantially as set forth.
