Improvements in Machinery for Automatically Actuating Apparatus
for Rousing, Aërating, Disturbing, or Knocking-down Worts or
other Liquids.
I WILLIAM PLOMER HARRIS of The Shirley Brewery Croydon in the County
of Surrey Brewer, do hereby declare the nature of my invention for AUTO-
MATICALLY ACTUATING APPARATUS FOR ROUSING, AERATING, DISTURBING
OR KNOCKING-DOWN WORTS OR OTHER LIQUIDS, and the manner in which the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The invention consists of a machine having, and the method of producing, all or
any of the following motions, viz. -hoisting or winding and lowering or unwinding
with accelerated speed, and reversing, with which is combined a resting period; to
effect the aforesaid motions, and the resting period I use toothed-wheels, belting,
clutch, or friction gearing to which I attach mechanical contrivances as hereinafter
described.
The machine is designed to work in a very small space, is perfectly automatic,
and may be regulated or adjusted to rouse, aërate, disturb, or knockdown almost
any depth of liquid or wort, and it will be found to be of great use in brewing and
other industries.
Hitherto the effectual rousing of worts and liquids has only been accomplished
by manual labour which always entails great expense; this machine is intended to
actuate rousing apparatus in exactly the mode a man would adopt when rousing in
the most approved manner, and this result is brought about by means of the
hoisting and lowering motions with acceleration of speed and the resting period,
which are the most important features of the invention.
It will, as just implied, supersede and almost entirely dispense with manual
labour in rousing etc. and will of necessity be much more reliable in its operation,
which is a matter of the very greatest importance.
::
The rouser, aërator, disturber, or knockerdown (hereinafter referred to as "the
rouser simply) to be worked in conjunction with or by means of the invention
may be similar to those usually employed for the purpose or of any special kind or
form.
The hoisting and lowering motions I prefer to accomplish with accelerated speed
both as the rouser is in the act of leaving and entering the wort or liquid (this
being readily effected by the adjustment of the machine) and to obtain this I use
an ordinary winding-drum or grooved-pulley each having differential gearing or
one or other of the arrangements hereinafter described :-
In the accompanying drawings

Except as to the studs c and K. J. in Figs. 1 and 4 respectively similar letters
of reference indicate like parts throughout the drawings.
1 connect the rouser to the winding drumm A in Figs. 1, 2, 4 and 6, or grooved-

page_text: pulley X X in Fig. 7, by means of a cord, wire, rope, chain, or other flexible
substance.
If preferred or desired a rod may be used in connection with and between the
rouser and the cord &c. so as to prevent the latter from entering the liquid: the
rod being much easier to keep clean and sweet than the cord &c.
Fig. 1. Power is transmitted through spindle B to clutch B 1. the latter
having at one end of it teeth, which engage in winding drum A which is of unequal
diameters, and when disengaged from the clutch is free to run on the spindle:
The worm B 2 driving worm wheel C is attached to the clutch which again is
driven by cotter and free to slide on the spindle.
When the machine is hoisting A, being of unequal diameters, winds for a time
at a given speed, and then at quickly increasing speed, until the maximum speed is
attained this being maintained for a shorter or longer period, as desired, by the
adjustment of stud e in slots c. 2, for, the worm B 2, having driven worm-wheel C,
the stud eventually comes in contact with stop e. 1. or other suitable contrivance,
thus arresting the motion of the worm wheel. Directly the motion of the worm
wheel is thus arrested, the clutch disengages from the winding drum and
simultaneously begins to compress spring N and liberates catch D which locks
inte notched wheel & thereby causing the winding drum (and therefore the rouser
connected with it) to become stationary for the required time according to
adjustment. By this means ample time is afforded, after the rouser has been
raised above the surface of the liquid or wort and before entering it again,
for any liquid or wort that may be in the rouser to run out in the meantime the
worm 2 working upon the worm wheel has been compressing the spring until
tappet F strikes arin E 1 of quadrant G according to the adjustment of the arm,
thus causing the quadrant to actuate the toothed-pinion G 1, which in its turn
moves the reversing-shaft-with-crank-end H, and thereby actuates reversing arm R,
which by means of toggle-links L and toothed wheels T immediately causes the
motion of spindle B and worm B 2 to be reversed, when the clutch B 1 disengages
catch D and the spring N forces the worm, and also the clutch, again into gear
with drum A, and reverses the motion of the latter, thus causing it to unwind (and
to lower the rouser) first at the maximum speed for a given time and afterwards
at a rapidly decreasing speed until the minimum or starting speed is again attained
which continues until the drum is unwound. In the meantime worm B 2 has
been actuating the worm-wheel and eventually causes stud c to come in contact
with collar M on reversing rod E, E which it moves thus putting quadrant arm E 2
into position for tappet to strike it and again reverse the motion of the spindle,
when the machine once more commences to hoist; W is a weight to aid the
reversing motion.
Fig. 4. In the machine shewn in this fig.-as in that in Fig. 1-power is
transmitted through spindle B, but winding-drum A of unequal diameters (but
of different construction to that. in Fig. 1) as also the worm B 2 are all rigidly
connected. Clutch Balthough it must always revolve the same way as the
spindle is so constructed that it is free to slide on it.
The reversing motion is here effected by means of toothed gearing A 1. A 2
and A 3 which are always in contact one with the other.
The machine is put into gear by the clutch B 1 coming in contact with A. 1 when
hoisting, and A2 when lowering or unwinding. When hoisting the winding-
drum A being, as just stated, of unequal diameters, winds for a time at a given
speed, and then at a rapidly increasing speed until the maximum speed is attained,
when it immediately begins to wind at a rapidly decreasing speed and continues to
do so until the minimum speed is attained, when, according to adjustment, the
motion is reversed, the reversing being brought about as follows:-
B2 having been running in the same direction as A and driving worm wheel C
eventually causes stud K to carry over the centre the reversing lever S and the
quadrant G to which it is coupled, thus causing reversing rod E-E to actuate

page_text: clutch-lever R 1. thereby putting the clutch B 1 in gear with A 2, and thus.
reversing the motion of the machine and immediately causing the drum to unwind.
first at the minimum speed and afterwards at a rapidly increasing speed (as in
hoisting) until the maximum speed is again attained, when the speed once more
begins to decrease and continues to do so until the speed at which it commenced to
wind is again attained, and this speed continues until the drum is unwound, when
the motion is again reversed and the machine commences to wind.
The decrease of speed at which the drum winds just before it has finished
hoisting and at which it begins to unwind again affords time for the rouser to.
empty.
When the machine is unwinding, B 2 causes the stud J to carry the reversing-
lever S over the centre by means similar to those described in reference to K when
the clutch B 1 was in gear with AI and the machine was hoisting. The exact
time at which it may be desired to cause the motion to be reversed may be.
regulated by adjusting the studs K and J in the slots c 2.
Fig. 7. The grooved-pulley arrangement shewn here provides an alternative.
method of hoisting and lowering with accelerated speed and may, with necessary
alterations, displace the winding drum A in Figs. 1 and 4. The grooved pulley X, X
works upon spindle B; is a nut adjustable upon ya screw-cut spindle and part
of B, with an arm 2, which is the means of actuating the reversing motion.
The arrangement works in the following manner :-
The grooved-pulley is attached to the spindle and therefore must revolve with
it, thus, in winding, causing the nut to travel along y until it comes in contact
with knuckle 63. which begins to press over the segment P, thereby at once-
causing X-X to wind at greatly accelerated speed. This continues until the
segment quite overlaps the pulley and the knuckle is hard against it, when .
begins to revolve with the spindle, and, 62 coming in contact with any suitable
reversing contrivance, immediately causes the motion of the spindle to be reversed
and the machines commences to unwind at the accelerated speed and continues to-
do so until the nut b, which at once begins to travel back again, gradually liberates
the knuckle and also P which is forced away from X-X by means of the spring N
when the machine unwinds at normal speed: this is maintained until its motion is
arrested by any suitable means and according to adjustment, when the arm b2
causes the motion to be reversed and the machine again begins to wind.
Fig. 8. The pulley arrangement shewn in this figure illustrates another method
of obtaining accelerated speed, and may be used in conjunction either with any of
the machines having the reversing motion hereinbefore particularly described (but
not necessarily having the winding drums of unequal diameters as shown in Figs. 1
and 4), or the moveable segment attached to the grooved-pulley shewn in Fig. 7.
a, is a cord or other flexible substance, fixed at one end, and at the other capable
of being actuated by any of the aforesaid machines. V, is an ordinary pulley
through which a runs, and to which the rouser is attached.
When the machine is in motion, winding, a passes through V, carrying upwards
the adjustable trigger a 1, until it comes in contact with the adjustable stop a 2,
when the speed of V is immediately accelerated, and this continues until the
actuating machine rests or reverses. When unwinding V begins to descend at the
accelerated speed and continues to do so for a given distance i.e., until a 1, which
has been in contact with a 2 leaves it, when V descends at normal speed.
In addition to the several machines herein before described and shewn in the
accompanying drawings I sometimes adopt one of somewhat simpler construction
designed to effect hoisting and lowering, but not necessarily reversing motions,
with or without accelerated speed, but without the resting period. The machine
drives continuously and comprises, spindle, winding drum, clutch, and worm-wheel
or other suitable arrangement.
When the drum has wound for the required distance the clutch driving it, is, by
suitable means, caused to disengage, and the drum is free to unwind which it does

page_text: by means of the weight of the rouser attached to it. In the meantime the clutch
: continues still to revolve the same way until the worm wheel or other arrangement
releases it and allows it to again engage with the drum, which when this takes place
once more commences to wind.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed, I declare that what I
claim is
