declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR
USE IN THE TREATMENT OF SEWAGE AND IN OTHER OPERATIONS IN WHICH SOLID
MATTER IS REQUIRED TO BE ADDED TO OR MIXED WITH FLUID MATTER IN
CERTAIN RELATIVE PROPORTIONS to be as follows:-
"
Our invention consists of the improvements hereinafter described in apparatus
for use in the chemical treatment of sewage by the addition thereto or mixture
therewith of solid matter in powder or in a moderately fine state of division and
for use in other operations in which solid matter in a like state is required to be
added to or mixed with fluid matter in certain relative proportions and the object
of our said Invention is to cause the flow of the sewage or other fluid to which the
solid matter is to be added or with which it is to be mixed to actuate apparatus
by which the latter is supplied or by which its supply is controlled. The mixture
of the said matters or the addition of the one to the other is thus effected
automatically.
According to our said Invention we mount a vessel of suitable form on pivots or
trunnions in such a position relatively to the mouth of a pipe or conduit whence
the fluid issues that the fluid so issuing shall pass into the said vessel and we so
arrange or counterbalance the said vessel that when it has received a certain
quantity of fluid it will turn on its pivots or trunnions and discharge the fluid it
has received and return to its original position ready to receive another charge of
the fluid. Above the said vessel we mount a hopper in which the solid matter to
be mixed with or added to the fluid is placed and in the lower part of the said,
hopper we arrange slides or valves one above the other at such a distance apart
that the space enclosed between them will contain the quantity of the said matter

page_text: which is required to be added to each charge of fluid in the aforesaid vessel. The
said slides or valves have openings formed in them which permit of the passage
from the hopper of the matter contained therein when by the sliding of the said
valves the openings in them are brought within the mouth of the hopper. These
valves we so arrange and so connect to the vessel hereinbefore described that on the
said vessel turning or tilting to discharge its contents the said valves are slidden in
one direction the lower one being thereby caused to close the mouth of the hopper
and the opening in the upper one being brought within the hopper and on the
said vessel returning to its original position the passage between the upper part of
the hopper and the space between the two valves is closed and the opening in-the
lower valve is brought within the hopper. The quantity of matter which on the
tilting of the aforesaid vessel passed into the space between the two valves is thus
allowed to fall into the said vessel.
By this means to each charge of fluid received by the said vessel a certain
quantity of the matter contained in the hopper is automatically added. The
quantity or proportion of the matter so added may be varied as required by
increasing or decreasing the capacity of the lower part of the hopper between the
two slides or valves.
In cases where the matter with which the hopper is charged is of such a nature
as to be liable to "
bridge" therein or not to descend when the slides or valves are
opened we mount or arrange in the hopper a stirrer consiting of a rotatory shaft
carrying arms which stirrer we so connect to the tilting vessel that at each motion
of the latter the said shaft is rotated or partly rotated.
Or we suspend or support the hopper by springs or otherwise so support it that
it may be capable of a vibratory motion and we connect the hopper to the tilting
vessel or to parts of the apparatus against which the said vessel strikes when tilted
and when it returns to its normal position in such a manner that on each motion of
the vessel the hopper is shaken or jogged whereby its contents are sufficiently
disturbed to ensure their descent as required.
If found necessary both the means hereinbefore described for ensuring the
descent of the contents of the hopper may be used conjointly.
In some cases instead of the slides or valves bereinbefore described we arrange
an Archimedian screw in the lower part of the hopper and on one end of the shaft
of the said screw (which shaft projects outside the hopper) we mount a ratchet
wheel with which is engaged a pawl so connected by a rod and lever or rods and
levers or other suitable means with the tilting vessel that on the said vessel
returning to its normal position after discharging its contents the said screw is
partly rotated and a certain quantity of the matter contained in the hopper is
thereby discharged into the said vessel. The quantity so discharged may be varied
as required by varying the position of the connection between the lever and rod by
which the pawl is actuated.
Or instead of mounting a screw in the hopper we arrange an endless band on
rollers under the mouth thereof and we connect one of the said rollers to the tilting
vessel by means of a ratchet wheel and pawl and rods and levers as in the case of
the archimedian screw. By this means an intermittent motion is communicated to
the band which as it travels under the mouth of the hopper carries forward a
certain quantity of the matter therefrom and deposits it in the said vessel.

WITH FLUID MATTER IN CERTAIN RELATIVE PROPORTIONS and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
Our invention consists of the improvements hereinafter described in apparatus
for use in the chemical treatment of sewage by the addition thereto or mixture
therewith of solid matter in powder or in a moderately fine state of division and
for use in other operations in which solid matter in a like state is required to be
added to or mixed with fluid matter in certain relative proportions and the object
of our said Invention is to cause the flow of the sewage or other fluid to which the
solid matter is to be added or with which it is to be mixed to actuate apparatus
by which the latter is supplied or by which its supply is controlled. The mixture
of the said matters or the addition of the one to the other is thus effected
automatically.
According to our said Invention we mount a vessel of suitable form on pivots or
trunnions in such a position relatively to the mouth of a pipe or conduit whence
the fluid issues that the fluid so issuing shall pass into the said vessel and we 'so
arrange or counterbalance the said vessel that when it has received a certain
quantity of fluid it will turn on its pivots or trunnions and discharge the fluid it
has received and return to its original position ready to receive another charge of
the fluid. Above the said vessel we mount a hopper in which the solid matter to
be mixed with or added to the fluid is placed and in the lower part of the said
hopper we arrange slides or valves one above the other at such a distance apart
that the space enclosed between them will contain the quantity of the said matter
which is required to be added to each charge of fluid in the aforesaid vessel. The
said slides or valves have openings formed in them which permit of the passage
from the hopper of the matter contained therein when by the sliding of the said
valves the openings in them are brought within the mouth of the hopper. These
valves we so arrange and so connect to the vessel hereinbefore described that on
the said vessel turning or tilting to discharge its contents the said valves are
slidden in one direction the lower one being thereby caused to close the mouth of
-

page_text: the hopper and the opening in the upper one being brought within the hopper and
on the said vessel returning to its original position the passage between the upper
part of the hopper and the space between the two valves is closed and the opening
in the lower valve is brought within the hopper. The quantity of matter which
on the tilting of the aforesaid vessel passed into the space between the two valves
is thus allowed to fall into the said vessel.
By this means to each charge of fluid received by the said vessel a certain
quantity of the matter contained in the hopper is automatically added. The
quantity or proportion of the matter so added may be varied as required by
increasing or decreasing the capacity of the lower part of the hopper between the
two slides or valves.
Figure 1 of the accompanying drawings is a plan and Figure 2 is a side elevation
partly in section (taken on the line Figure 1) of an apparatus constructed as
herein before described. The same letters and figures of reference indicate the
same parts in each of the said Figures 1 and 2 and in the other Figures hereinafter
referred to of the accompanying drawings.
A is the vessel for receiving the fluid a¹ a¹ are the trunnions on which it turns
the said trunnions working in bearings 6' 6 secured to uprights 63 b² supported by
a base or frame B: a is an arın secured to the vessel A and carrying an adjustable
weight or counterbalance a³ which arm rests on a support b³ when the vessel is in
its normal position which position it occupies when empty and while being charged
with fluid. The weight a³ is secured at such a distance from the vessel A that
when the said vessel has received the required quantity of fluid it will turn on its
trunnions a¹ a¹.and discharge the fluid it has received. C is the hopper which is
supported above the vessel A on a frame 6 secured between the uprights 6 b².
DE are the slides or valves in the lower part of the said hopper and d¹ c¹ are the
openings in the said valves. The valve D is.connected to the vessel A. by a cord d
and to the arm a² by a cord d³ and the valve E is similarly connected to the said
vessel and arm by cords e² e³ which cords d² d³ e² es pass over pulleys working in
brackets 665 secured to the frame b¹.
The method of using the apparatus herein before described and its action are as
follows: The apparatus being so arranged relatively to the conduit conveying the
fluid to be treated that the said fluid will pass into the vessel A the hopper C is
charged with the solid matter, to be added to or mixed with the fluid and the
weight a³ is so adjusted on the arm a² as to admit of the vessel A tilting and
discharging its contents when filled or nearly filled with the fluid to be treated
which is then allowed to pass into the said vessel A. When the quantity of the
fluid which has been passed into the said vessel is sufficient to overbalance it it
turns on its pivots or trunnions and discharges its contents the tilting of the said
vessel A causing the slides or valves D E to be actuated as follows:-On the said
vessel descending to discharge its contents the cords d e are pulled and the said
slides D E thereby drawn from left to right the lower part of the mouth of the
hopper being first closed by the slide E and the upper part of the mouth of the
hopper subsequently opened by the aperture in the slide D being brought within
the hopper when a portion of the matter contained in the hopper descends into the
space between the two slides. On the vessel A returning to its normal position the
slides are restored to the positions shown in the drawings by means of the cords d³ e³
connected to the arm a² and the quantity of matter which had descended into the
space between the slides falls into the vessel A. The quantity of matter discharged
from the hopper at each action of the apparatus may be increased or decreased by
increasing or decreasing the capacity of the lower part of the hopper between the
slides D. E.
In cases where the matter with which the hopper is charged is of such a nature
as to be liable to impede the motion of the slides D E to such an extent as to
prevent the vessel A from tilting and discharging its contents when filled we allow
sufficient slack in the cords de to admit of the vessel A starting and acquiring
sufficient momentum to overcome the resistance to the motion of the said slides

page_text: before the said cords are drawn tight. The slides are thus started with a jerk and
the said resistance is overcome the force with which the slides are acted on when
started being in proportion to the momentum acquired by the vessel A which
momentum is greater or less according to the amount of slack in the said corda.
In some cases instead of the slides or valves hereinbefore described we arrange
an Archimedian screw in the lower part of the hopper and on one end of the shaft.
of the said screw (which shaft projects outside the hopper) we mount a ratchet
wheel with which is engaged a pawl so connected by a rod and lever or rods and
levers or other suitable means with the tilting vessel that on the said vessel
returning to its normal position after discharging its contents the said screw is
partly rotated and a certain quantity of the matter contained in the hopper is
thereby discharged into the said vessel.
This arrangement is illustrated in Figures 3. 4 and 5 of the accompanying
drawings Figures 3 and 4 being elevations taken at right angles to each other and
Figure 5 a plan Figure 6 is a separate view of a portion of the apparatus. In the
said Figures and in the Figures hereinafter referred to of the accompanying
drawings parts similar to those described with reference to Figures 1 and 2 are
marked with corresponding letters and figures of reference but such parts are not
again described.
F is the Archimedian screw mounted in the hopper C. f¹ is the shaft of the
said screw G is the ratchet wheel keyed to the projecting end of the said shaft
g is the pawl engaging with the teeth of the said ratchet wheel which pawl is
carried by and jointed to a lever f³ working freely on the shaft fl. H is a rod
jointed at its upper end to the said lever f' and at its lower end to an arm a*
secured by a screw a* to the projecting end of one of the trunnions a¹ a¹ on which
the vessel A works. The hopper is shown separately in section (taken on the
line
Figure 5) in Figure 6 c¹ is an inclined block which prevents the matter
contained in the hopper from passing out otherwise than by the action of the
screw F and c is a shoot by which the matter passing from the hopper is directed.
into the vessel A.
The action of this arrangement is as follows:-On the vessel A tilting to
discharge its contents the parts g¹ f' H and a* are brought into the positions
indicated in dotted lines in Figure 4 and on the said vessel returning to its normal
position the engagement of the pawl g¹ with the teeth of the ratchet wheel G
causes the screw F to be partly rotated and a portion of the matter contained in
the hopper is thereby discharged into the said vessel A. The quantity so dis-
charged may be varied as required by connecting the rod H. nearer to or farther
from the free end of the arm a*.
'
Instead of mounting a screw in the hopper we in some cases arrange an endless
band on rollers under the mouth thereof and we connect one of the said rollers to
the tilting vessel by means of a ratchet wheel and pawl and rods and levers as in
the case of the archimedian screw. By this means an intermittent motion is com-
municated to the band which as it travels under the mouth of the hopper
carries forward a certain quantity of the matter therefrom and deposits it in the
said vessel.
This arrangement is illustrated in Figure 7 of the accompanying drawings in
which Figure the hopper is shown in section and part of one of the uprights
supporting the hopper and the base or frame supporting the said uprights are
omitted.
I is the endless band and are the rollers on which it is mounted the axes
of the said rollers working in bearings ³ ³ secured to the uprights 62 62. The
arrangement of the ratchet wheel and the parts by which it is actuated is similar to
that of the like parts hereinbefore described with reference to Figures 3, 4 and 5
and the said parts are marked with letters and figures of reference corresponding
to those in the said Figures 3, 4 and 5. cis a sliding plate arranged in the
hopper C by raising or lowering which plate the quantity of matter discharged
from the hopper at each action of the mechanism may be regulated. As will be

page_text: seen by an examination of the said Figure 7 the ratchet wheel G is actuated
only on the return of the vessel A to its normal position after discharging its
contents.
In cases where the matter with which the hopper is charged is of such a nature
as to be liable to "bridge" therein or not to descend when the mechanism for dis-
charging it is actuated we mount or arrange in the hopper a stirrer consisting of a
rotatory shaft carrying arms which stirrer we so connect to the tilting vessel that
at each motion of the latter the said shaft is rotated or partly rotated.
Or we
suspend or support the hopper by springs or otherwise so support it that it may
be capable of a vibratory motion and we connect the hopper to the tilting vessel
or to parts of the apparatus against which the said vessel strikes when tilted and
when it returns to its normal position in such a manner that on each motion of the
vessel the hopper is shaken or jogged whereby its contents are sufficiently disturbed
to ensure their descent as required.
Figure 8 of the accompanying drawings is a vertical section of part of an
apparatus of the kind hereinbefore described with reference to Figure 7 showing
the arrangement in the hopper of a stirrer and the connections by which it is
actuated by the motion of the vessel A. J is the rotatory shaft working in
bearings in the hopper C ³ ³ are the arms carried by the said shaft J and K
is a cord secured at one end to the vessel A and at the other end to the arm a³
and passing around a pulley secured to the shaft J and over pulleys k¹ k¹
working in brackets secured to the hopper C. By this arrangement the
matter in the hopper is agitated each time the vessel A turns on its trunnions
rotatory motion being imparted to the shaft J from the said vessel by means of the
cord K. Figure 9 of the accompanying drawings is a plan and Figure 10 is a
vertical section taken on the line 3 Figure 9 of an apparatus of the kind herein-
before described with reference to Figure 7 showing the arrangement of springs for
supporting the hopper and the means by which the hopper is shaken. LL are
rods constituting the springs hereinbefore referred to which rods are secured at
their lower ends to the uprights 62 62 and at their upper ends to the hopper C
which is supported solely by. the said rods L L. Grooves bb are formed in the
uprights 66 in which grooves the said rods work the extent of their vibration
being limited by the width of the said grooves. One of the said rods is shown
separately in elevation in Figure 11. M is a hammer mounted on a spring.
stem m¹ secured to the side of the vessel A which hammer when the vessel A
returns to its normal position after being tilted strikes an arm c* secured to and
projecting from the hopper C the contents of which are thus shaken each time the
apparatus is actuated.
The arrangements hereinbefore described with reference to Figure 8 of the
accompanying drawings for stirring the contents of the hopper and that herein-
before described with reference to Figures 9 and 10 of the accompanying drawings
for shaking the hopper may be used conjointly where desirable and either one
or other or both of the said arrangements may be combined with any of the
forms of apparatus herein before described and illustrated in the accompanying
drawings.
