Improvements in Valves Applicable for the Outlets of Sewage
Tanks, Barrels, and the like.
J, JOHN GREENWOOD of Cowling near Crosshills, via Leeds in the County of York,
Blacksmith do hereby declare the nature of this invention to be as follows, that is to
say:
It consists of improvements in valves applicable for the outlets of sewage tanks,
barrels and the like whereby the efficiency of these valves is greatly enhanced.
This is attained by forming the grooves in which the outer edges of each valve,
slide or operate, of a suitable taper form or with their outer edges or sides at an
incline to the face of part against which the valve slides, from this it will be seen
that as the valve is pushed to cover the opening, by the inclined sides of the
grooves in which it slides, it will be pressed and made to do so efficiently. Again
by this formation of the grooves it will be seen that the removal of the valve from
covering the opening is greatly facilitated since by a very slight movement it will
be drawn and relieved of the pressure of the inclined sides.
The bottom edge of the valve is made thin or somewhat sharp so that in descending
to cover the opening, should anything such as small pieces of wood &c. be in its
path, as by having only partly entered therein, it will cut them away and so accomplish
the object desired.
Suitable levers and connecting rods are employed in connection with this valve by
which the operator may manipulate it from any desired position.
In most cases the valve is arranged to operate vertically so that it may be weighted
to obtain the return movement, by which means when not held it always closes the
opening.

Improvements in Valves Applicable for the Outlets of Sewage
Tanks, Barrels, and the like.
I, JOHN GREENWOOD of Cowling near Crosshills, via Leeds, in the County of York,
Blacksmith, 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 :-
It consists of improvements in the construction, formation and arrangement of
valves and of parts in connection therewith applicable for the outlets of sewage tanks,
barrels and the like, whereby the efficiency of these valves is greatly enhanced.
In order that this invention may be more readily understood I have hereunto
appended sheets of drawings illustrative thereof wherein fig. is a front view of the
valve and parts in connection therewith, the valve being shewn as closed. Fig. 2 is
a similar view to fig. 1, but the valve is shewn as being open. Figs. 3 and 4 are
side sectional views of figs. 1 and 2 respectively. Fig. 5 is sectional side view of a
tank or cistern shewing application of valve and means for operating same. Figs. 6
and 7 are end and side views respectively of a box-cart (or sower-cart) with valve
and means for operating same attached thereto.
Similar figures and letters refer to similar parts throughout the several views.
The object of this invention is attained by forming the grooves a in which the
outer edges b² (which are somewhat wedge shaped) of the valve b, slide or operate,
of a suitable taper form, or with their outer edges or sides a at an incline to the
face of the part c against which the valve slides, from this it will be seen that as
the valve is pushed to cover the opening it will be pressed and made to do so
efficiently.
Again by this formation of the grooves a it will be seen that the removal of the
valve 6 from covering the opening d is greatly facilitated since by a very slight
movement it will be drawn and releived of the binding effect of the inclined sides of
said grooves a.
The bottom edge 3 of the valve b is made thin or somewhat sharp so that in
descending to cover the opening d, should anything such as small pieces of wood etc.
be in its path, as by having only partly entered therein, it will cut them away and
accomplish the object desired.
When the valve b with its other parts, is used in connection with the outlet of a
tank or cistern e, as shewn by fig. 5, it may be operated by the bell-cranked lever f
to which it is connected by the rod g. To this lever fa rod (or even string) h night
be attached by which the valve b may be operated at almost any desired distance
therefrom.
When the valve b is applied to a box-cart (or sewer-cart) as shewn by figs. 6 and 7,
the lever is used to operate same. This lever being mounted to the hind part of
the box and coupled to the valve b by the rod ³, having at its outer end the cord

page_text: attached to it; this cord. being made to pass over the pulley m and along the shaft n
to be attached to the slidable handle o so that the driver of the horse or other animal
drawing the box-cart, may operate the valve b without leaving his position in charge
of said animal.
A screw b is attached to the valve b and made to operate within a slot formed in
the part c, by which means the valve b is prevented from being drawn, by the operator,
out of proper connection with said part c.
In most cases as is shown by figs. 5, and 6, the valve 6 is arranged to operate
vertically so that it may be weighted to insure its return movement, by which means
when not held it always closes the opening. However it will readily be seen that
other arrangements of levers etc. may be employed and the valve b may be placed in
any other desired position.
The plate p and the boards are used in connection with the valve b when said
valve is attached to a box cart so that by these means as the liquid flows from said
box cart through said valve and strikes or rushes against the plate pit is guided and
made to spread all over the upper surface of the boards from the edges of which it
flows and is in this way evenly distributed upon or over the ground.
The plate p is adjustable on its bearings so that when the box is full of liquid, which
will consequently rush out with, greater force than when same is nearly empty, it
(said plate p) may be placed at a suitable distance further from the orifice covered by
the valve b, and moved near thereto as the quantity of liquid in the box cart diminishes
as will be well understood.
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 valve 6 having wedge shaped edges 163, and the partc having the taper
grooves a formed by the parts a¹ being at an angle to said part in combination
substantially as and for the purposes specified.
2. The valve part c, rod g lever f, rod (or string) h, and cistern e in combination
substantially as and for the purposes specified.
.
3. The valve part c rod k lever I cord 1, bowl or pulley m, handle o and box-
cart in combination, all being constructed and arranged to operate in the manner
and for the purpose substantially as herein specified.
4. The valve b, part c, plate p and its suitable bearings, board s, rod k¹, lever f¹
cord 7 bowl or pulley m, and box cart in combination, all being constructed and
arranged to operate in the manner and for the purpose substantially as herein
specified.
