hollow archimedean screw enclosed within a suitable chamber or casing into.
which the lower end of the hopper opens, and the lower end of the chamber
or casing at the bottom of the screw is left open. The screw is formed
hollow and perforated on the upper surface with a number of small holes,
and with a few on the under side of the upper and lower edges of the screw.
The hollow serew may be formed upon a vertical pipe, which is fitted with a
rose jet on the top, and may be perforated in the side for a short distance

page_text: down from the top. The hollow screw and vertical stand pipe is fitted with
a supply pipe for water or other liquid for saturating the malt or other
granulated material as it falls from the hopper through the volutes of the
screw into the mash tub or other vessel. Or, if preferred, in place of the
hollow archimedian screw, or in combination therewith, a number of hollow
shelves may be used, which intersect each other and have their tops inclined
at an angle to the horizon in alternate opposite directions, and which are
perforated on their upper surfaces and on the outer edges thereof for allowing
the supply of water or other liquid to escape and saturate the malt or other
granulated substance as it passes over the oblique surface from shelf to shelf.
It is preferred to enclose the shelves within an oval or square casing. The
action of the apparatus is as follows:-The crushed malt or other granulated
substance is thrown into the hopper, which is fitted at the bottom with a slide
for cutting off or regulating the discharge, the slide being set to give
the required amount of discharge. The heated water or other saturating
liquid is then turned on and is brought into contact with the malt or other
granulated substances as it passes through the screw and over the shelves,
carrying the malt or other granulated substance with it into the mash tub or
other recptacle which is placed immediately beneath.

page_text: for "IMPROVEMENTS IN SELF-ACTING MASHING OR SATURATING APPARATUS FOR THE
USE OF BREWERS, DISTILLERS, AND OTHERS," upon the condition (amongst others)
that I, the said William Henry Mellor, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Henry Mellor, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
:-
This my said Invention has for its object a peculiar and simple apparatus
for mashing or saturating malt or other granulated material as it falls from a
hopper into the brewer's maslı tub or other receptacle, and may consist of a
fixed hollow archimedián screw enclosed within a suitable chamber or casing,
into which the lower end of the hopper opens, and the lower end of the
chamber or casing at the bottom of the screw is left open. The screw I form
hollow and perforate on the upper surface with a number of small holes, and
with a few on the under side of the upper and lower edges of the screw. The
hollow screw may be formed upon a vertical pipe, which is fitted with a rose
jet on the top, and which pipe may be perforated in the side for a short.
distance down from the top. The hollow screw and vertical stand pipe is fitted
with a supply pipe for water or other liquid for saturating the malt or other
granulated material as it falls from the hopper through the volutes of the
screw into the. mash tub or other vessel. In some cases 1 prefer, in place of
the hollow archimedian screw, or in combination therewith, to use a number
of hollow shelves which intersect each other, and have their tops inclined at
an angle to the horizon in alternate opposite directions, which I perforate on
their upper surfaces and on the outer edges thereof for allowing the supply of
water or other liquid to escape and saturate the malt or other granulated
I prefer
substance as it passes over the oblique surface from shelf to shelf.
to enclose the shelves within an oval or square casing.
That this my said Invention may be the more readily seen and understood,
I have hereunto annexed Drawings illustrating the practical mode of applying
the Invention, like letters and figures marked thereon being used to denote
similar parts.
Figure 1 is an external elevation of a hopper, to the throat of which is
fitted one modification of my improved mashing or saturating apparatus

page_text: suspended immediately above the mash tub; Figure 2 is a vertical section of
one modification of my improved mashing or saturating apparatus, having the
form of an archimedean screw enclosed within a troncated, conical, open
bottom vessel or casing; and Figure 8 is a top view or plan of the same.
Figure 4 is another modification of the apparatus constructed with inclined
hollow shelves, and Figure 5 is a section of the same, taken from a to b.
The modifications illustrated may be used seperately or conjointly, that is
to say, the screw-form portion of the apparatus may be used to receive the
grain or other granulated material to be saturated by being connected to the
throat of the hopper, and fitting the inclined shelf portion, illustrated in
Figures 4 and 5, with a small hopper on top, into which the saturated
material from the screw may be received when it passes over the inclined
shelves and into the mash tub; or the inclined shelf portion of the apparatus
may first receive the malt or other granulated material, and the whole of the
apparatus, if preferred, may be enclosed in one case or external covering, in
which case either the screw portion or the inclined planes may be placed on
the top.
A, supply hopper, which is fitted with B, a slide for cutting off or regu-
lating the discharge of the malt or other granulated material to be saturated;
C, supports for supply hopper; D, supports for E, the saturating apparatus,
which is suspended by F, rods formed with eyes on the upper end, through
which is passed G, a short supporting rod; H, hot water, or other saturating
liquid supply pipe, which is shown broken off, and fitted with K, a stop-cock ;.
L, the mash tub, which may be of the ordinary or any other description; M
(Figure 2), a hollow archimedean screw perforated on the upper surface with
a number of small holes for the escape of the saturating liquid; N (Figure 2),
a vertical stand pipe with a conical head, and perforated on the top and side
with a number of small holes, and the lower end of which opens into the
interior of the hollow screw, so as to receive therefrom the supply of
saturating liquid; P (Figures 4 and 5), hollow shelves or inclined planes,
which are closely perforated with a number of small holes on the upper sur-
face, and all of which except the bottom one are also perforated with a number
of holes through the under side, and which are connected to an outer cover or
casing through which the saturating liquid is introduced into the hollow
shelves through suitable supply pipes, and which makes its escape through
the multifarious small holes in the shelves or iuclined planes.
The action of the apparatus is as follows:-The crushed malt or other
granulated substance is thrown into the hopper, which is fitted at the bottom
with a slide for cutting off or regulating the supply of material to be saturated.

page_text: The slide being set to give the required amount of discharge, the heated
water or other saturating liquid I turn on and through a supply pipe commu-
nicating with the interior of the hollow screw, shelves, and stand pipe, when
it escapes through the multitudinous small holes described, and is thus
brought into contact with the malt or other granulated substances as it passes
through the screw and over the shelves, carrying the malt or other granulated
substance with it into the mash tub or other receptacle placed immediately
beneath:
Having now fully described and ascertained the nature of this my said
Invention, and how I believe the same may be best carried into practical
effect, I wish it to be understood that I do not confine myself to the precise
details, relative proportions, or dimensions herein-before described and set
forth, as it will be readily seen the same may be considerably varied without
departing from the Invention; but what I claim is,-
First, the construction and use of a mashing or saturating apparatus
formed with a hollow archimedeau screw perforated on the upper surface and
enclosed within an outer open bottom casing, substantially in the manner and
for the purposes herein-before described and set forth.
Secondly, the use of the inclined, intersecting, hollow, perforated shelves,
with their enclosing casing and supply pipes, as herein-before described and
set forth, when applied to the construction of masbing or saturating
apparatus.
And, lastly, the construction and use of the improved self-acting mashing
or saturating apparatus as herein-before described and set forth.
In witness whereof, I, the said William Henry Mellor, have hereunto
set my hand and affixed my seal, this First day of December, in the
year of our Lord One thousand eight hundred and sixty-four.
