COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Mashing and
Brewing Ale, Beer, and other Fermented Liquors.
I, JOHN BARTON, of St. Marks, Dewsbury, in the County of York, Architect
and Surveyor, 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 :-
This invention relates to an improved combination form of brewing apparatus,
for the mashing and brewing of ale, beer, and other similar beverages, and is
designed to commence and complete the various operations of boiling the water,
mashing or brewing the malt and hops, and cooling, working, and fermenting the
liquor in one and the same vessel, and is especially adapted for home or domestic use,
and for small brewers, for sale; but is capable of being used on a much larger scale.
Hitherto brewers of this character although excellent in some respects, have been
deficient in others; and this invention has for its object the removal of all proved
deficiencies, and the conversion of the apparatus into an entirely perfect and useful
contrivance, by performing the various operations of brewing consecutively with
greater ease and despatch, and without removal.
Referring to Figures 1 and 2 on the accompanying drawings, which are intended
to form part of this Specification, (but before referring in detail to the respective
parts, would have it understood that I do not confine myself to the exact details
shewn, as they may be modified without departing or evading the true intent and
meaning of my invention.
Figure 1, is a vertical section of my apparatus shewing the internal parts of the
same.
Figure 2, is a side elevation of the said apparatus.
The cast or wrought iron stand A supporting the copper or other metal vat B,
forms the heating chamber, in which the combustion of solid, gaseous. or liquid fuel
is established, and which chamber is carried up and embraces the vat B to one
half or more its whole height, so giving increased heating surface.
From the side of this stand A there are two side projections or standards C, one
side thereof carrying a pivot bracket D, and also holding the upper termination of
the turntable pivot bolt H; the lower termination of this pivot is held by a foot
bracket casting W, attached to the cast iron stand A.
The turntable and pivot bracket D, carries the bevil gearing F, which rotate by
means of handle and shaft E a central threaded screw-shaft G, which shaft is
provided with groove and key pin to prevent turning. The lower termination of
the central screw shaft G is attached to a perforated masher vessel L by the
attachment bar I, and being acted upon by the bevil gearing F, the masher vessel
and refrigerator coil N is raised or depressed at will through or above the hot
liquor vessel or vat B.
The attachment bar I provides against any obstruction in the masher vessel and
leaves the space entirely open and free for containing the grains, raw materials, and
other ingredients that may be used.
The masher vessel L is provided with a perforated bottom through which the
liquor strains; the sides of which are made sufficiently deep to hold the whole of
the grains and raw materials used, (generally of a size one third the whole capacity
of the vessel or vat B) and that such raw materials and grains may be raise
through and above the vessel or vat B, for draining and guaging purposes, and may
also be turned to one side for the removal of grains and cleaning purposes by
putting into operation the whole of the top turning gearing which travels on turn-
table and pivot bracket D, and is securely fixed and held in position by the pivot
bolt H, and fastner and catch V. To obviate friction small steel wheels aro

page_text: inserted in underside of travelling turning gearing and rim upon the top surface of
turntable D.
In the centre of the perforated bottom of the masher L a sliding door Mis
provided to allow of the admission of yeast or other fermenting agents, and to
facilitate the removal of the grains and other spent materials used, from the masher
vessel.
To the underside of the masher vessel and also actuated by the previously
named screw and bevil gearing, is secured the cooler or refrigerator N, constructed
with double, treble, or quadruple concentric coils held together by cross pieces,
sustaining and tension bars, and through which cold or hot water can be circulated
as required, by the attachment of suitable unions and hose pipes to inlet J³ and
outlet J. The beforementioned cooler may also be used as an attemporator during
the fermentation of the liquor in vessel B by the circulation of tepid water through
the same.
To meet the requirements of sparging or washing the grains, provision is made
for the attachment of a rose sparger J to the outlet pipe J, by means of which,
attached to hose piping J2 any remaining saccharine is extracted from the grains
with water direct from the cooler coil N.
O is the tap for the removal of the finished liquor.
In order to obviate the difficulty of elevating the masher vessel owing to the
production of vacuum in the vessel B, the air inlet pipe K is provided, which
suppresses the formation of the same.
The heating agent is preferably towns or generator gas from a Thwaites gas
generator on account of cleanliness and easy regulation of heat, but I asually
employ air gas rings P, with slitted or drilled circular orifices, the air and gas
being aspired or admitted through the regulating ball Q, the gas supply pipe R
being coupled up by flexible or permanent tubes to the mains.
A liquor level gauge graduated in gallons is provided as shewn at S; alongside
of which I provide also a thermometer T to indicate the temperature of the liquor
during the progress of the brewing operation.
The sides of the brewing vessel are strengthened and ornamented externally by
brass or other metal hoops U.
:―
I effect the brewing operations in the following manner viz. :-
Cold water is introduced through the inlet hose J³, to the desired quantity into
the vessel B, which is indicated by liquor level gauge S marked to a scale of
gallons, and heated to the required temperature. The malt or other raw material
is then introduced into the masher vessel L, and allowed to remain sufficiently long
to extract the saccharine, or juicy matter therefrom, which may be facilitated by
elevating or depressing the masher vessel L and its contents through the hot water,
the products settling into the vat or vessel B, after which the masher vessel L is
by means of the screw G and bevil gearing F, elevated above the main vessel B
and by means of the turntable and pivot H, is swung clear of the entire machine.
and the spent grains extracted by the sliding door M. The hops or other flavouring
substitute are now placed in the masher vessel L, lowered into the liquor and boiled
to the required gravity, after which it is cooled by passing cold water through the
refrigerator coil pipes N. The spent hops are now discharged by means similarly
used for the grains, the washer vessel being again lowered and yeast or other
ingredient introduced through the sliding door M for fermentation, or the liquor
may be run off at this stage by means of the discharge cock O, and fermented in a
separate vessel, leaving the apparatus at liberty for future operations.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I would have it understood
that I do not limit myself to the precise details shown and described, but I declare
that what I do claim is :-
1. The general combination arrangement of brewing apparatus, substantially as
shown and described.

page_text: 2. In apparatus for brewing in which a masher vessel and coil refrigerator are
employed in the manner set forth, the employment of gearing whereby swinging
turning and travelling motions can be imparted to the masher vessel so that it and
that the coil refrigerator can be swung clear of the boiling copper or vat,
substantially as and for the purposes such as shown and described.
3. The construction of brewing apparatus having the boiling copper or vat B
arranged within the heating chamber A substantially as set forth.
4. In brewing apparatus of the kind herein shown and described the employment
of air pipes to prevent the formation of vacuum within the boiling copper or vat so
that the washer vessel can be raised without difficulty, substantially as set
forth.
5. In brewing apparatus of the kind herein referred to the employment of means
for readily indicating the level and temperature of the liquor as shown and
described.
6. In brewing apparatus of the kind herein referred to the employment of the
sparging and washing arrangement in connection with the outlet pipe as shown
and described.
7. In brewing apparatus of the kind herein referred to, the combination and
arrangement of the screw and attachment bar as and for the purposes such as shown
and described.
8. In brewing apparatus of the kind herein referred to the employment of means
for preventing the screw and masher vessel from turning within the copper or
vat B, such as shown and described.
