SPENCER, all of the Castle Brewery, St George's Road, Southwark in the County
of Surrey, Consulting Practical Brewers and Analytical Chemists, do hereby
declare the nature of this invention to be as follows:-
Our present invention has for its object improvements upon an invention for
which Letters Patent were granted to us dated January 26. 1881 No. 344 and
relates to an improved arrangement of apparatus for feeding or supplying the
steaming apparatus with the grain or cereal under treatment and for discharging
the same therefrom after the steaming operation has been completed thereon.
When using the arrangement of feeding and discharging apparatus described in
the specification of the aforesaid patent, it sometimes occurs that the soaked grain
cereal adheres to and clogs up the feeding apparatus thereby interfering with its
action and causing a larger expenditure of power in driving the same.
Now by using feeding apparatus constructed according to our present invention
we obviate or greatly reduce the difficulty above referred to. For this purpose in
lieu of employing two pistons fixed at a short distance from each other on the
piston rod and moving to and fro in a line with the piston rod within a horizontal
cylinder provided with suitable feeding and discharge apertures as described in our
said specification we employ a comparatively short or shallow cylinder mounted
with its ends or covers in borizontal planes; a feeding aperture is made in the
upper end or cover of such cylinder and a discharge aperture in the lower end or
cover thereof, such apertures being on opposites of the axis of the cylinder.
Within this cylinder is fitted a closely fitting piston or drum the rod or axis of
which extends through a suitable stuffing box in the top end or cover of the
cylinder and receives a step by step rotary motion by any suitable driving gear.
Through this piston or drum a number of chambers are formed, preferably
four, these chambers are each approximately of the form of a quarter of the piston
or drum with the angles rounded off and a sufficient substance left between and

page_text: around them; they are also formed somewhat larger at their lower ends than at
their upper ends to facilitate clearance of the grain or cereal passing therethrough.
On the top end or cover of the cylinder over the discharge aperture we fix a
steam pipe or box with a slit or number of openings therein so as to enable a sheet
or body of steam to pass through the chambers in the piston or drum to fully
discharge the contents thereof or we mount on the upper cylinder cover a steam
tight chamber in which is placed a plug or piston fitting the upper end of the
chambers in the feeding piston or drum and which at proper times is caused to
descend and thereby force out the contents of such chambers and to rise again out
of the way to permit of the rotation of the feeding piston or drum.
The discharging apparatus is of a similar construction to the above except that
the discharging steam jet or plug or piston is not required.

SPENCER all of the Castle Brewery, St George's Road, Southwark in the County
of Surrey, Consulting Practical Brewers and Analytical Chemists 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:-
:
Our present invention has for its object 'improvements upon an invention for
which Letters Patent were granted to us dated January 26-1881 No. 344 and
relates to an improved arrangement of apparatus for feeding or supplying the
steaming apparatus with the grain or cereal under treatment and for discharging
same thereform after the steaming operation has been completed thereon.
When using the arrangement of feeding and discharging apparatus described in
the specification of the aforesaid patent it sometimes occurs that the soaked grain
or cereal adheres to and clogs up the feeding apparatus thereby interfering with
its action and causing a larger expenditure of power in driving the same.
Now by using feeding apparatus constructed according to our present invention
we obviate or greatly reduce the difficulty above referred to. For this purpose in .
lieu of employing two pistons fixed at a short distance from each other on the
piston rod and moving to and fro, in a line with the piston rod within a horizontal
cylinder provided with suitable feeding and discharge apertures as described in our
said specification we employ a comparatively short or shallow cylinder mounted
with its ends or covers in horizontal planes; a feeding aperture is made in the
upper end or cover of such cylinder and a discharge aperture in the lower end or
cover thereof, such apertures being on opposite sides of the axis of the cylinder.
Within this cylinder is fitted a closely fitting piston or drum the rod or axis of
which extends through a suitable staffing box in the top end or cover of the
cylinder and receives, according to one arrangement a continuous rotary motion
and in another, a step by step rotary motion by any suitable driving gear.
Through this piston or drum a number of chambers are formed, preferably four,
these chambers are each approximately of the form of a quarter of the piston or
drum with the angles rounded off and a sufficient substance left between and
around them; they are also formed somewhat larger at their lower ends than at-
their upper ends to facilitate clearance of the grain or cereal passing therethrough.
On the top end or cover of the cylinder over the discharge aperture we fix a
steam pipe or box with a slit or number of openings; therein so as to enable a
sheet or body of steam to pass through the chambers in the piston or drum to fully
discharge the contents thereof or we mount on the upper cylinder cover a steam

tight chamber in which is placed a plug or piston fitting the upper end of the
chambers in the feeding piston or drum and which at proper times is caused to
descend and thereby force out the contents of such chambers and to rise again out
of the way to permit of the rotation of the feeding piston or drum.
The discharging apparatus is of a similar construction to the above except that
the discharging steam jet or plug or piston is not required.
And in order that our said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.

section and Figure 7 is a plan of part thereof separately. Figure 8 is an elevation
partly in section, Figure 9 is a plan or top view and Figure 10 is an underside
view of the bottom plate of our improved delivery apparatus: Figure 11 is an
elevation partly in section and Figure 12 is a plan representing a modification and
Figures 13, 14 and 15 are detail views of separate parts thereof.
In all the Figures like parts are indicated by similar letters of reference
A, represents a steam-tight cylinder B, is a shaft or axis passing centrally through
the same and fitted with paddles or stirrers C, so formed that in their rotation
within the cylinder they prevent the grain or cereal therein from adhering to the
cylinder and at the same time gradually advance it from the feed end to the
delivery end of the cylinder. Motion is given to the shaft B, in the following
manner.
On the shaft or axis B, is fixed a toothed wheel B¹ which is taken into by a
toothed pinion D¹ fixed on a shaft or axis D on which are also mounted the fast
and loose pulleys D8, D³, which receive motion by a strap or band from any suitable
motive power.
The shaft or axle B, where it passes through the end or cover of the cylinder A
passes through a stuffing box Ai whereby the cylinder is retained steam tight at
such part. E is a safety valve, F is a pipe leading steam from the boiler to the
cylinder A, and fitted with a suitable stop cock and G is a steam discharge pipe
which is also fitted with a stop cock.
The steaming apparatus so far as it is above described, forms no part of our
present invention.
H, is the feed apparatus and I is the discharge apparatus which according to our
present invention are constructed in the following manner, h is the top plate of
the feed apparatus h¹ is the bottom plate and h³ is a cylindrical jacket to which
the plates h h¹ are fixed steam tight; a feeding aperture h³ is made in the upper
plate or cover h which is connected by a suitable tube or shoot with the supply
hopper h*; a discharge aperture h is made in the lower plate or cover h¹ and such
apertures h³h are made on opposite sides of the axis of the cylinder. Within
the cylinder 2 is a closely fitting piston or drum ho to which the axis h³ is securely
fixed and the latter extends through a stuffing box h in the top plate or cover
and receives a continuous, or it may be a step by step rotary motion by any suitable
driving gear. Through this piston or drum h a number of chambers 18 are formed,
preferably four, these chambers are each approximately of the form of a quarter
of the piston or drum h with the angles-rounded off and a sufficient substance left
between and around them; they are also formed somewhat larger at their lower
ends than at their upper ends to facilitate clearance of the grain or cereal passing
therethrough,

page_text: On the top plate or cover h of the cylinder we fix a steam pipe and box h³ with
a slit or number of openings 10 in the bottom thereof so as to enable a sheet or
body of steam to pass through the chambers 8 to fully discharge the contents
thereof or in lieu thereof we may employ the arrangement of apparatus shown at
Figures 11 to 15 which will be hereinafter described.
The discharge apparatus I is of a similar construction to the above, that is to say
it is formed with top and bottom plates i, i, cylindrical jacket i, a receiving
aperture in the upper plate or cover i and a discharge aperture in the lower
plate or cover i', a drum is formed with chambers is and fixed on the axis i³ which
latter passes through a stuffing box ; this discharge apparatus I does not however
require either the discharging steam jet or the discharging plug shown at Figures 11
to 15.
The discharge apparatus I is also formed with a man hole and cover 10 in the
bottom plate in line with the receiving aperture in the upper plate in order that
a direct passage may be made when required therethrough to facilitate the
discharging of the cylinder A when it is not under steam pressure.
The following is the mode in which we give a continuous rotary motion to the
drums h, On the axis h³ ³ are.fixed respectively chain wheels h¹, ³, and these
are driven by chains j, k, which receive motion from chain wheels m¹, fixed
respectively on the shafts or axles l m which by bevel wheels 1 m³ receive motion
from bevel wheels n' n² mounted on the shaft or axle n to which rotary motion is
given in the following manner.
On the axis n is fixed a chain wheel n which receives rotary motion from
a chain n' which is driven by a chain wheel B' fixed on the axis B.
The bevel wheels n¹ n³ are mounted loosely on their shaft n but are capable of
being connected therewith by clutches n' n³ operated by levers nº n so as to
enable the feed apparatus H and discharge apparatus I to be thrown either
separately or together into or out of action as may be desired.
In the modification represented at Figures 11 to 15 the discharging steam jet of
the feed apparatus I is dispensed with and a plug or piston r fitting the upper part
of the chambers h8 is used in lieu thereof; on the upper plate or cover h is mounted
a steam tight chamber h¹ which receives the plug or piston r when the latter is in
its higbest position, that is to say, clear of the chambers h; the rod 71 of the plug
or piston r passes through a stuffing box on the steam chamber h¹.
In this arrangement the axis h is made in two parts connected together by
clutches 13 h the former being fixed to the lower part of the axis h³ whilst the
latter is mounted with capability of sliding up and down on the upper part of
such axis but by a feather is compelled to revolve therewith; the upper part of
the axis h³ receives a continuous rotary motion and when the two clutches h¹³ h¹4
are in gear with each other the drum or piston he is revolved but when, in the
rotation of the upper part of the axis h the cam groove his around the clutch /¹
by acting in combination with the fixed stud a causes such clutch h¹ to rise and
therefore to separate from the clutch h¹ the drum or piston he will remain
stationary; at such time the cam he acts upon the upper end of the rod and
forces the plug or piston r downwards and thereby discharges the contents of the
chamber h in line therewith into the steaming cylinder A; a spring ³ keeps the
rod of such plug or piston r against the cam h¹6 and thereby raises the plug or
piston r in the further rotation of the upper part of the axis h³ to the position
shown in the drawing after which the clutch h¹ is caused to descend into gear
with the clutch ¹³ when the drum or piston he will again revolve until a fresh
chamber he is brought under the plug or piston r when the motions above described
will be repeated.
Figures 13 and 14 represent the cams 16 and 16 produced in a plane.
We would here remark that other methods of giving motion to the various
parts may be adopted without departing from the peculiar character of our
invention so long as the motions above described are produced.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
The improved feed apparatus and discharge apparatus substantially as herein
shown and described and for the purpose stated.
