HENRY LONG of Armoury Square Stapleton Road Bristol and HENRY APLIN
of 4 Victoria Road Redfield in the Parish of St. Georges in the County of
Gloucester "IMPROVEMENTS IN APPARATUS FOR ROUSING AND AERATING BEER.'
This Invention has for its object improvements in apparatus for rousing and
aerating beer.
For these purposes we arrange a vertical cylinder or trunk within a vat in which
the beer is contained, and in the centre of the cylinder is a vertical axis carrying a
screw like propellor at its lower end. There is also a pipe or pipes passing down
the cylinder or trunk and air is forced into these by means of an air feeder or
forcing apparatus. This consists of air chambers with folding sides, and fitted
with valves; these chambers are expanded and collapsed by connecting rods
passing from cranks upon an horizontal axis to an intermediate moveable partition
separating the two air chambers and the partition is thus moved up and down.
There is a receiver on the top of the upper air chamber and both of the air
chambers deliver the air into the receiver, and it is led from thence to the cylinder
or trunk within the vat. The crank axis is driven from any convenient motor by
a strap passing around a pulley upon the axis. The propellor is driven in a similar
manner and as it revolves it draws the liquid down the cylinder or trunk; at the
bottom thereof the liquid meets the air forced by the air feeder into the pipe or
pipes connected with the cylinder or trunk and the air is delivered by them in the
immediate vicinity of the propellor, or the propellor then breaks up and divides
the entering streams of air and effects the intimate admixture of the air with the
liquid.

page_text: g is a box or case forming the frame of the machine and carrying the bearings
of the cranked axis h. The axis is rotated by manual labour or by power and it
has upon it the fly wheel h¹, a cord also passes around the wheel and connects the
machine with the rouser. i. i. are connecting rods coupling the crank with the
trunnions or studs k. k. fixed upon the sides of a moveable chest ; they are
guided within the case g, by the straight guides g¹. g. Above and below the
chest 1, there are collapsible chambers m, and n, they are formed of leather or
other suitable material nailed on to the chest; also to the top and bottom
slabs o and p, and to the intermediate frames q, q. The slabs o and p are fixed
within the case g. Beneath the slab p, there is a chamber r; it is filled with
cotton wool to arrest dust and other impurities and its sides are perforated for the
admission of air. 8, is a flap valve permitting air to pass from the chamber r, into
the collapsible chamber n. The chest, is also filled with cotton wool to strain the
air. The air passes out of the chest by the valve t, into the collapsible chamber m.
The sides of the chest are perforated that air may enter it from the interior of
the case g, by which air is able to enter the case. There are passages not shown
in the drawing and these passages also contain cotton wool. Thus as the chest
is moved up and down, in consequence of its connection with the crank, air enters
the chambers m and n, alternately. The air is expelled from the chamber m,
through the valve u, into the stationary wind chest v, and from this the pipe f,
leads to the vat or vats. From the chamber m, also the air is expelled and driven
into the wind chest v, by the passage w, and a valve x, prevents its return.
Having thus described the nature of our said invention and the manner of
performing the same we would have it understood that we claim :—
First, Our improved rousing and aerating apparatus, substantially as described.
Second, Our apparatus for aerating beer, substantially as described.
In witness whereof I the said Henry Aplin have hereunto set my hand and
seal this Fourteenth day of September in the year of our Lord One
thousand eight hundred and eighty two.
