I RICHARD RICHARDSON HUTCHINSON of 114 Edith Grove Brompton London S. W.
Electrical and Mechanical Engineer 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 :-
My Invention relates to the performance of the operation of "mashing" or mixing
the grist with hot liquor, in brewing malt liquors and the like, and. apparatus for
applying and using electricity as a motive power therefor.
In order that my Invention may be clearly understood, reference may be had to
the accompanying two sheets of drawings in which Figure 1 Sheet 1 is an elevational
view of a "masher" provided with an electric motor for directly operating it,
according to my Invention, and Figure 2 is an end elevation of the same, Figure 3
is a cross section of the tube or barrel of the improved "masher" or
mixer," and
Figures 4 and 5 front and back end views of the same and Figure 6, Sheet 2 is a
sectional view of a tub masher or mixer, and Figure 7 a sectional view of a tub or
tun masher and barrel masher combined.
In carrying out my Invention 1 employ a barrel or hollow cylinder A. Figure 1 in
which is supported by suitable bearings a spindle H, upon which is fixed or attached
radial arms B, part of the barrel A is shewn broken away for the purpose of illustrating
the device. C is the grist case or hopper, and D is a slide for regulating the descent
of the grist into the masher barrel A-The spindle H may be coupled directly to the
spindle H of the electric motor E, or I may employ suitable gearing between said
spindles The hot liquor is admitted into the barrel A by the cock or valve I, so
that it may become thoroughly mixed and incorporated with the grist, the consistence
of the mash being regulated by the degree of opening allowed to the slide D and the
cock or valve I. In this way I am enabled to apply a current of electricity through
the electric motor E for the purpose of rotating the spindle H carrying the arms B,

interior surface of the barrel A, stationary arms, also radially placed, and intervening
between each set of rotating arms, to further aid the process of mixing or mashing,
as hereinbefore referred to.
provide as an alternative arrangement, according to my Invention, shewn by
Figures 3, 4 and 5, Sheet 1 in which the barrel A is of elliptical or oblong cross
section, and carries two spindles a and upon which are mounted alternately, two sets
of arms B B. The front end view of the barrel A, Figure 4 shews the general
arrangement of this device, and Figure 5, representing the back end view, shows
the method of driving or operating the spindles a, b. Two spur wheels, c and c¹ are
respectively attached to the ends of said spindles a and b, both spur wheels and e¹
engaging with the teeth of the pinion d which may be rotated by the spindle of an
electric motor, either by being directly attached thereto, or by the intervention of
suitable gearing.
C
The device illustrated by Figures 3, 4, and 5 Sheet 1, and hereinbefore described
admits of the thorough admixture of the grist and liquor, and also the disintegration
of lumps, which are prejudicial to the mash.
I may however, in certain cases, employ a circular tun tub or vat G, Figure 6.
Sheet 2, in the interior of which I place an annular rack, around which may travel
a shaft or spindle carrying mixing arms e, and gearing with said rack by means of
a pinion keyed or otherwise attached to the extremity thereof.
Motion is imparted to said spindle and arms by means of the bevel wheels c―d,
which are rotated by the electric motor E through the outer set of bevel wheels b―a.
The grist and liquor is thoroughly incorporated and mashed within the tun tub or
vat C by means of the revolving arms e operated by the electric motor E in the
manner hereinbefore described, and when the process is completed, the resultant
liquor may be drawn off by the pipe g, the perforated false floor acting as a strainer
to prevent the grist from passing with said liquor.
As an alternative arrangement I may employ a tun vat or circular chamber G,
Figure 7, Sheet 2 also provided with revolving arms e and a rack the former in
this case being driven from beneath, by the bevil wheels a- operated by the electric
motor E.
I may also make use of either of the forms of "masher or mixer shewn by Figures 1
and 2 and Figures 3, 4, and 5, Sheet 1, respectively; in combination with the fore-
going as shewn by J Figure 7 Sheet 2. Motion is imparted to the spindle or
spindles and arms of the masher or mixer J from the electric motor E by means of
the pullies and i and the endless band or belt J. The grist and liquor are fed into,
and partially mixed by, the masher or mixer J, before being discharged into the vat
or chamber masher or mixer G, and from said tun vat or chamber; the liquor may
be drawn off when the process is complete by the pipe y.
I may in cases where the tun vat or chamber C is of small diameter, place the
electrical motor vertically and drive the central spindle directly therefrom, either
above or below the vat or chamber.
Although I have shewn the device or contrivance according to my Invention
applied to brewing processes, I wish it to be understood that the same is also
applicable to other purposes and processes of a like nature.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
First. The application of an Electric motor or motors to mashing or mixing
machines for brewing or other purposes substantially as herein described.
Second. In a single or double spindle "masher
:: or mixer the combination there-
with of an electric motor for actuating same substantially as herein described and
shewn in the accompanying drawings.
Third. In a mashing or mixing machine, the combination of a tun vat or
chamber G Figures 6 and 7, Sheet 2 with revolving arms e, and an electric motor E

page_text: either arranged to rotate said mixer or masher from above or below the tun vat or
chamber G substantially as herein described and shewn in the accompanying two
sheets of drawings.
Fourth. In a mashing or mixing machine, the combination of a barrel masher or
mixer J, Figure 7, Sheet 2, with a tun, vat or chamber G, revolving arms e and an
electric motor E substantially as herein described and shewn by the accompanying
drawings.
