WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. IMPROVEMENTS IN MACHINERY OR MILLS
FOR GRINDING CORN OR OTHER MATERIALS." [A communication from abroad by
John Fitz Gerald, of Brooklyn, New York, United States of America.]
My Invention relates to grinding mills, and comprises the combination of parts
and devices hereinafter described, constructed, and arranged as set forth, whereby
the cooling of the upper and lower grinding stoues is accomplished, and whereby
either air or water may be employed at pleasure as the cooling medium, and the
change may be made from one to the other if desired without re-arrangement or
alteration of the parts. It also comprises the combination with the principal
grinding stones of a mill having-a couical plate fixed to the lower or moving
stone about the axis on the upper side thereof of a cylindrical hopper capable of
vertical adjustment in the eye of the casing of the upper or stationary stone, and
having cast upon it or otherwise rigidly secured to it on the interior at its baso
line the feeding ring valve hereinafter described, together with the radial arms and
adjusting screws hereinafter specified.
The object of the first part of my Invention is two fold; first, the accomplishment
of the cooling of both the upper or stationary grinding stone and the lower or
moving grinding stone; and, second, such an arrangement and construction of the
devices employed to accomplish the cooling of the stones, that said devices aro
adapted for the use of either air or water as the cooling medium, and that a change

page_text: may be made from one to the other without alteration or re-arrangement of said
devices, and also whereby the centrifugal force generated in the lower or revolving
grinding stone is utilized to facilitate the circulation of the cooling medium over
and around the stone and more particularly when water is employed, said cooling
medium being admitted to the cooling chambers at the centre of the stone and
discharged at the periphery.
In carrying the said Invention into practice, I provide a casing which contains
the cooling chambers of and in which the upper stone is supported and centred,
which is preferably accomplished by means of set screws; there is also a casing con-
taining the cooling chambers, of and in which the lower stone is seated, and centred
preferably by means of similar set-screws. A conical plate or disc is secured upon
the centre of the lower or moving stone, and is held in place by bolts passing
into the casing of the said lower stone, and the inclined outer face of this plate serves
to guide the material to the ground between the stones; the interior of this plate is
preferably chambered, and the chamber is at the centre of the casing of the lower
stone, which chamber is about the hub of said casing and stone.
To accomplish the cooling of the upper or stationary stone I employ the
following devices:-Water or air is admitted under pressure through a main
supply pipe, and passes thence through branch pipes which may be more or less in
number, as will be hereafter apparent, to the cooling chamber about the upper
stone; these chambers are constituted as follows:-The casing of the upper stone
is of somewhat greater diameter than the stone itself, so that a space or chamber
exists between the outer edge of the stone and the outer circumferential wall or
flange of the easing. Upon the interior face or roof of the casing is cast or other-
wise formed or fixed a circular projection, which is so placed that when the stone
is seated in the casing the projection will fit upon the upper facing or back of the
stone at or near to the outer edge thereof, whereby a chamber upon the back of
the stone and a separate and distinct one on the circumference are constituted.
The chamber about the circumference of the stone is then divided into subchambers
by means of radial partitions, and these subdivisions may be more or less in
Dumber, but I find that for all practical purposes a subdivision into two distinct
sub-chambers by means of diametrically opposite radial partitions is preferable.
Into each of these circunferential chambers, and preferably midway between the
ends thereof, opens one of the supply pipes through which the cooling medium is
admitted, and as many supply pipes as there are sub-divisions should be provided.
The chamber constituted upon the back of the stone, as hereinbefore described,
is then divided into subchambers by means of radial partitions extending from the
interior circumferential wall of the casing to the circular projection or partition,
and by means of partitions which are carried inward to the interior circumferential
wall. These subdivisions may be more or less in number, but I find it preferable
to arrange them to constitute four subchambers and to have them in pairs in their
positions relative to the sub-division of the circumferential chamber.
At the ends of each subdivision of the chamber which are most remote from the
supply pipes, are cut or formed gates or openings in the projecting partition, a
separate one opening into each of the subdivisions constituting the pair adjacent
to each subdivision; a discharge or escape pipe leads from the cooling chambers of
the upper stone; this pipe is conveniently provided with branches leading
preferably to each pair of adjacent subdivisions, the partitions which separate said
pairs being in this arrangement preferably cut away, so that communication is had
to a single one of the branch pipes of the discharge pipe from both of the sub-
divisions constituting the pair.
I prefer that these should be within each of the subdivisions irregularly placed
projections or lugs which are cast or otherwise formed or fixed upon the interior
face of the casing and extend to the upper face of the upper stone, and which
serve to break up and thoroughly distribute the cooling medium over the face of
the stone. It is evident that the cooling medium, whether air or water, will pass
through each of the subdivisions of the chamber around the circumference of the

page_text: chamber around the circumference of the stone to the gates at each of the opposite
ends thereof, and through these gates into cach of the pairs of chambers over
the upper face of the stone and thence out to the discharge pipe, and that
this circulation being maintained, the effectual cooling of the upper stone will be
accomplished. It is also evident that the upper stone being stationary, and con-
sequently the circulation of the cooling medium being caused by the pressure
thereof with no centrifugal force to impede or overcome it, the circulation of the
cooling medium may be the reverse of that specified, without materially changing
the principle of my said Invention.
་
To effect the cooling of the lower or moving stone I employ the following
devices: The main supply pipe leads through the hopper to and through the
crown of the plate to the chamber with which it communicates. By this means
the cooling medium, be it air or water, is admitted under pressure to the cooling
chambers of the lower stone. These chambers are constituted as follows:-About
the hub of the casing which holds the stone is formed a chamber; upon the interior
face of the lower casing is cast or otherwise formed or fixed a circular projection,
which is so placed that when the stone is seated in the casing the projection will
fit upon the back. of the stone at or near the outer edge thereof, thus forming a
chamber or space between the back of the stone and the interior face of the casing,
and the diameter of the casing being somewhat greater than the diameter of the
stone a space or chamber is constituted between the edge of the stone and the
outer circumferential wall of the casing. The space or chamber formed on the face
of the stone by the projection is divided into chambers by means of radial
partitions, and these chambers may be more or less in number. The circumferential
space I also then divide into chambers, and I find it preferable so to divide this
space that the chambers upon the back of the stone are arranged in pairs in their
relation to the subdivisions of the circumferential chamber, and this I accomplish
by extending each alternate one of the before named radial partitions out to a
juncture with the face of the circumferential wall of the casing. If desired the
circumferential chamber may be divided into chambers, equal in number to the
subdivisions of the chamber on the back of the stone. Into each one of the
chambers on the face of the stone, constituting a pair, are gates opening from
the central hub-chamber, and at a point in each of said chambers, the most remote
from said gate in the partition, is a gate opening into the circumferential chamber,
the gates of two adjacent chambers preferably opening into the same subdivision
of said chamber. At the point in each subdivision of said circumferential chamber
most remote from the gates, and leading into it are discharge openings in the plate
or wall of the casing, and said discharge openings are preferably provided with.
downwardly extended short pipes or nozzles, which range in their revolution with
the lower stone, over a circular trough which is supported on a cross piece of the
main frame. From the trough an over-flow pipe extends to the main discharge-pipe.
I find it preferable to arrange irregularly placed projections in the chambers on
the face of the stone to serve the same purpose as that named for the other
projections.
It is evident that either water or air may be employed as the cooling medium,
or that a change may be made from one to the other at pleasure without altering,
rearranging, or disturbing my prescribed device.
The circumferential chambers on each of the stones are closed in by means of
rings, which are fitted upon the periphery of the stones and secured to the outer
walls or flanges of the casings.
The second feature of my Invention relates to the feed devices. The eye of the
casing of the upper stone has a vertical flange, the interior face of which is turned
off smooth to fit the exterior of the cylindrical hopper, the outer surface of which
is also turned off. The hopper is arranged to fit neatly to the Banged eye of the
casing, and it has feathers which fit into suitable grooves in the said flange's eye
to hold the hopper stationary with the upper grinder. The base line of the hopper

page_text: extends downward to the plane of the base line of a conical plate, and it has cast
upon its interior face at said base line a ring.
The under face of the ring is fitted to the upper face of the conical plate, and
has cut or formed in it a radial feed groove.
The upper face of the ring slopes upward to the line of the interior of the
hopper. Upon the upper part of the hopper, preferably at the mouth thereof, are
cast or otherwise rigidly fixed radial arms or lugs. A threaded opening is cut in
each of these arms or lugs, with which opening engages the upper end of the
vertical adjusting screw, the lower ends of said screw working in steps on the
upper face of the casing of the stone. Stirring or mixing devices may be arranged
to revolve within the hopper to cause the thorough mixing and agitation of the
contained material. It is well known that in order to secure the best results in
grinding the material to be ground should be fed to the stones with precision and
in a certain and unvarying quantity.
It is also well known that it frequently becomes necessary to alter and regulate
the feed of the material to the grinding stones in order to accomplish satisfactory
results.
When my described hopper is charged with material to be ground and the
hopper is lowered until the ring rests upon the conical plate and the mill is set in
motion, if the feed is not fast enough through the grooves the ring may be,raised
more or less above and away from said plate by turning the adjusting screws, the
hopper carrying the ring being thus moved vertically in the eye of the casing of
the upper stone. And it is evident that an exceeding nice and close adjustment
of the ring and the plate constituting the feed devices to each other may be thus
accomplished. The weight of the hopper and its contained material will generally
be found sufficient to cause the ring to bear properly upon the plate; but if tho
emergency occurs the hopper may be weighted at the lugs.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN MACHINERY OR MILLS
FOR GRINDING CORN OR OTHER MATERIALS." A communication from abroad by
John Fitz Gerald, of Brooklyn, New York, United States of America.
My Invention relates to grinding mills, and comprises the devices and combi-
nations of parts hereinafter described, constructed and arranged as set forth,
whereby the cooling of the upper and lower grinding stones is accomplished, and
whereby either air or water may be employed at pleasure as the cooling medium,
and the change may be made from one to the other if desired without re-arrange-
ment or alteration of the parts. It also comprises the combination with the
principal grinding stones of a mill, having a conical plate fixed to the lower or
moving stone about the axis on the upper side thereof, of a cylindrical hopper
capable of vertical adjustment in the eye of the casing of the upper or stationary
stone, and having cast upon it or otherwise rigidly secured to it on its interior at
its base line the feed ring-valve hereinafter described, together with_the_radial
arms and adjusting screws hereinafter specified. In the accompanying Drawing,―
Figure 1 is a vertical section of a grinding mill embodying my Invention.
Figure 2 is a plan of the same partly in section on line x, x, Figure 1, and
shewing in dotted lines the arrangement of the cooling chambers of the upper stone
and their supply and exhaust or discharge pipes.
Figure 3 is a side elevation of a mill embodying my Invention.
Figure 4 is a sectional plan of the casing of the lower or moving grinding stone,
the said stone being removed.
Figure 5 is a bottom plan of my improved hopper and feed ring-valve.
Figure 6 is a top plan of the same.
The object of the first part of my Invention is two-fold; first, the accomplish-
ment of the cooling of both the upper or stationary grinding stone, and the lower
or moving grinding stone; and, second, such an arrangement and construction of
the devices employed to accomplish the cooling of the stones, that the said devices
are adapted for the use of either air or water as the cooling medium, and that a
change may be made from one to the other without alteration or re-arrangement of
the said devices, and also whereby the centrifugal force generated in the lower or
revolving grinding stone is utilized to facilitate the circulation of the cooling
medium over and around the stone, and more particularly when water is employed
the said cooling medium being admitted to the cooling chambers at the centre of the
stone, and discharged at the periphery.
A is the upper or stationary grinding stone, and B the lower or moving grinding
stone. A is the casing which contains the cooling chambers of and in which the
upper stone A is supported and centred, which is preferably accomplished by means
of set-screws as shewn. B¹ is the casing which contains the cooling chambers of
and in which the lower stone B is seated and centred, preferably by means of
similar set-screws as shown. C is the spindle upon which the lower stone B is
hung, and by means of which it is revolved. D is the frame which supports the
various parts. E is the hopper into which the material to be ground is, placed, and
from which it is fed to the stones A, B. A conical plate or disc F is secured upon
the centre of the lower or moving stone B, and is held in place by bolts passing
into the casing B¹ of the said lower stone, and the inclined outer face of this plate

page_text: serves to guide the material to be ground between the stones; the interior of this
plate is preferably chambered as at f, and the chamber bis at the centre of the
casing B¹ of the lower stone, which chamber is about the hub of the said casing and
stone, as shewn in Figures 1 and 4.
To accomplish the cooling of the upper or stationary stone A, I employ the
following devices, that is to say, water or air is admitted under pressure through
the main supply pipe C, and passes thence through the branch pipes c, c', (which
may be more or less in number, as will be hereinafter apparent) to the cooling
chambers about the upper stone. These chambers are constituted as follows:-The
casing A¹ of the stone A is of somewhat greater diameter than the stone itself, so
that a space or chamber a exists between the outer edge of the stone and the outer
circumferential wall or flange of the casing. Upon the interior face or roof of the
casing is cast, fixed, or otherwise formed a circular projection a', Figure 2, which
is so placed that when the stone is inserted in the casing, the projection will fit
upon the upper facing or back of the stone at or near to the outer edge thereof,
whereby a chamber upon the back of the stone, and a separate and distinct one on
the circumference are constituted. The chamber a about the circumference of the
stone is divided into sub-chambers by means of radial partitions a², and these
sub-divisions may be more or less in number, but for all practical purposes a sub-
division into two distinct sub-chambers by means of diametrically opposite radial
partitions, as shown in Figure 2, is preferable. Into each of these circumferential
chambers, and preferably midway between the ends thereof, opens one of the
supply-pipes c, c, through which the cooling medium is admitted, and as many
supply pipes as there are sub-divisions should be provided.
The chamber constructed upon the back of the stone, as herein before described,
is also divided into sub-chambers by means of radial partitions a³, a', extending
from the interior circumferential wall of the casing to the circular projection or
partition a', and by means of the partitions a which are carried inward to the
interior circumferential wall, as shown in Figure 2. These sub-divisions may be
more or less in number, but it is preferable to arrange them as shown to constitute
four sub-chainbers a, a, a, a, and to have them in pairs in their positions.
relative to the sub division of the circumferential chamber.
At the ends of each sub division of the chamber a, which are most remote from
the supply-pipes c, c', are cut or formed gates or openings a³ in the projecting
partition a', a separate one opening into each of the sub-divisions a³, a, a, a³,
constituting the pair adjacent to each sub division of a. D' is the discharge or
escape pipe leading from the cooling chambers of the upper stone A. This pipe is
conveniently provided with branches d, d', leading preferably to each pair of
adjacent sub-divisions a, a, and a, a, as shown, the partitions as, at, which separate
the said pairs, being in this arrangement preferably cut away, so that communi-
cation is had to a single one of the branch pipes d, d', from both of the sub-divisions
constituting the pair.
I prefer that there should be within each of the sub-divisions a, a, a, a³,
irregularly placed projections or lugs a¹, which are cast or otherwise formed or
fixed upon the interior face of the casing, and extend to the upper face of the
stone A, and which servo to break up and thoroughly distribute the cooling medium
over the face of the stone. The cooling medium, whether air or water, entering
through c, c', will pass through each of the sub-divisions of the chamber a around
the circumference of the stone to the gates at each of the opposite ends thereof,
and through these gates into each of the pairs of chambers a³, aº, and a7, as, over
the upper face of the stone, and thence out through d, d', to the discharge pipe D',
and that this circulation being maintained, the effectual cooling of the upper stone
will be accomplished. It is evident that the stone A being stationary, and con-
sequently the circulation of the cooling medium being caused by the pressure or
headway thereof, with no centrifugal force to impede or overcome it, the circulation
of the cooling medium may be the reverse of that specified without materially
changing the principle of my said Invention.

page_text: To effect the cooling of the lower or moving stone B I employ the following
devices, that is to say, the main supply pipe C leads through the hopper to and
through the crown of the plate F to the chamber b with which it communicates;
by this means the cooling medium, whether air or water, is admitted under pressure
to the cooling chambers of the lower stone B. These chambers are constituted as
follows: About the hub of the casing which holds the stone is formed the
chamber b, as shown plainly in Figure 4. Upon the interior face of the casing B
is cast or otherwise formed or fixed the circular projection 6', which is so placed
that when the stone is seated in the casing the projection 6' will fit upon the back
of the stone at or near the outer edge thereof, thus forming a chamber or space
between the back of the stone and the interior face of the casing, and the diameter
of the casing being somewhat greater than the diameter of the stone, a space or
chamber is constituted between the edge of the stone and the outer circumferential
wall of the casing, as shewn at 62. The space or chamber formed on the face of
the stone by the projection b' is divided into chambers 63, b', 6º, 6º, 6º, 6º, by
means of partitions 60, 610, 61, 61, 613, 614, and these chambers may be more or less
in number, but they should be as shown and specified for the most effectual
operation of my said Invention. The circumferential space b³ I also divide into
chambers, and it is preferable so to divide this space that the chambers upon the
back of the stone are arranged in pairs in their relation to the sub-divisions of the
circumferential chamber 6, and this I accomplish by extending each alternate one
of the before named radial partitions out to a juncture with the face of the
circumferential wall of the casing, as shown plainly in Figure 4. If desired the
chamber may be divided into chambers equal in number to the sub-divisions of
the chamber on the back of the stone. Into each one of the chambers on the face
of the stone constituting a pair the gates 615 open from the central hub chamber b,
and at a point in each of the said chambers, the most reinote from the said gate 615
in the partition b', is a gate b¹ opening into the circumferential chamber, the gates
of two adjacent chambers preferably opening into the same sub-division of the said
chamber 6. At the point in each sub-division of the said circumferential chamber
most remote from the gates 610 which lead into it from the chambers 63, 64, 6º, bº,
67, 68, aro discharge openings 617 in the plate or wall of the casing, and the said
discharge openings are preferably provided with downwardly extended short pipes
or nozzles 618, as shown in Figure 1, which range in their revolution with the
stone B over a circular trough G which is supported on a cross piece of the main
frame From this trough a pipe g extends to the main discharge pipe D¹, Figure 1.
It is preferable to arrange irregularly placed projections 61 in the chambers on
the face of the stone to serve the same purpose as that named for the projections a¹º
The cooling medium, whether air or water, admitted under pressure to the
chamber b will pass through the gates 6 into each chamber of the several pairs
(whatever their number) on the back of the stone, and circulating through these
chambers over the back of the stone will pass thence from each pair through
gates 616 to one of the sub-divisions of the circumferential chamber, then around
the circumference of the stone, and thence will escape through the openings 617;
and when water is the cooling medium it will be caught in the trough G and
carried from thence to the main discharge pipe D¹. It is evident that the cooling
medium being admitted to the chambers at the centre of the stone, and wholly
discharged at the periphery thereof, instead of having to overcome by pressure or
headway given to the cooling medium, the centrifugal force generated by the
revolution of the stone B as is necessary in cooling devices which admit the cooling
medium at the periphery of the stone and discharge it at the centre, or which
return it to the centre for discharge, by means of my described devices and their
construction and arrangement upon the said stone I am enabled to utilize the said
centrifugal force in assisting the rapid and complete circulation of the cooling
nedium over the face of and around the circumference of the stone, and to facilitate
ts discharge which takes place wholly at the periphery of the stone. Either water

page_text: or air may be employed as the cooling medium, or a change may be made from one
to the other without altering, rearranging, or distributing my described devices.
The second part of my Invention relates to the feed devices, and is shewn in
Figures 1, 5, and 6. The eye M of the casing A¹ of the upper stone has the
vertical flange ml, the interior face of which is turned off smooth to fit the exterior
of the cylindrical hopper E, the outer surface of which is also turned off. The
hopper is arranged to fit neatly to the flanged eye M of the casing, and it has
feathers m which fit into suitable grooves in the said flanged eye to hold the
hopper stationary with the grinder A. The base line of the hopper extends
downward to the plane of the base line of the conical plate F, and it has cast upon
its interior face at the said base line the ring D. The under face of the ring D² is
fitted to the upper face of the conical plate F, and has cut or formed in it the
radial feed grooves do, as shown plainly in Figure 5. The upper face of the ring
slopes upward to the line of the interior of the hopper. Upon the upper part of
the hopper E, preferably at the mouth thereof, are cast or otherwise rigidly fixed
the radial arms or lugs n. A threaded opening is cut in each of these arms or
lugs, with which opening engages the upper end of a vertical adjusting screw n¹,
the lower ends of the said screws working in steps n³ on the upper face of the
casing of the stone A, as shown. Stirring or mixing devices may be arranged to
revolve within the hopper to cause the thorough mixing and agitation of the
contained material. It is well known that in order to secure the best results in
grinding, the material to be ground should be fed to the stones with precision, and
in a certain and unvarying quantity. It is also well known that it frequently
becomes necessary to alter and regulate the feed of the material to the grinding
stones in order to accomplish satisfactory results. When my described hopper is
charged with material to be ground, and the hopper is lowered until the ring D³
rests upon the conical plate F, and the mill is set in motion if the feed is not fast
enough through the grooves do, the ring D² may be raised more or less above and
away from the said plate by turning the adjusting screws n¹, the hopper carrying
the ring being thus moved vertically in the eye of the casing of the upper stone;
and it is evident that a very nice and close adjustment of the ring D² and plate F
constituting the feed devices to each other may be thus accomplished.
The weight of the hopper and its contained material will generally be found
suflicient to cause the ring D' to bear properly upon the plate F; but if necessary
the hopper inay be weighted at the lugs, as shown.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it under-
stood that I claim,―
First. In a grinding mill, the combination with the upper or stationary grinding
stone A of the casing A', the said casing being of greater diameter than the stone,
and having the circular projection a' upon its inner face, as described, thus coll-
stituting a circumferential chamber about the periphery and a chamber upon the
back of the stone, the said circumferential chamber being divided by radial
partitions into chambers or sub-divisions, more or less in number, each sub-division
being provided with an inlet-pipe about midway between the ends thereof, and
with a gate at each end thereof. opening into one of each of the chambers or sub-
divisions into which the aforesaid chamber on the back of the stone is divided by
means of radial partitions, as shown, and which subdivisions are of such number
and arrangement relatively to the sub-divisions of the circumferential chamber as
to be in pairs, as specified, each pair being provided with a common outlet-pipe,
all as described and for the purpose set forth.
Second. In a grinding mill, the combination with the lower or moving stone B
of the casing B', the said casing being of greater diameter than the stone, and
having the circular projection & upon its inner face, as described, thus constituting a
circumferential chamber about the periphery of the stone, and a chamber upon
the back of the stone, the said chamber on one back of the stone being divided by

page_text: radial partitions into chambers or sub-divisions, more or less in number, each sub-
division having an inlet gate 6" leading into it from a chamber b about the hub or
centre of the stone, and a gate be leading from it at a point in its opposite wall
most remote from the said inlet gate into a sub-division of the aforesaid circum-
ferential chamber about the periphery of the stone, which sub-division is provided
with a discharge-opening 617 at a point in the wall thereof most remote from the
gate 616, with or without the trough G, all substantially as described and for the
purposes specified.
Third. In a grinding mill, the combination with the lower or moving stone B,
having the conical plate F fixed about its hub, and the upper or stationary stone A
having the casing A' with the flanged and grooved eye M of the cylindrical

movement in the eye of the said casing A¹, and having cast or otherwise rigidly
fixed to its interior at its. base-line the feed ring-valve D, together with the arins
or lugs n and the vertical adjusting screws n, all constructed and combined to
operate as and for the purpose specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Sixth day of April, in the year of our Lord One
thousand eight bundred and eighty two.
