PROVISIONAL SPECIFICATION.
Improved Disintegrator or Corn Mill.
-
I GUSTAV BINDER of Sennefeldergasse 2, Vienna in the Empire of Austria
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved disintegrator or corn mill, and has for
its object to produce meal which is not only very fine, but also uniform in size, no
matter what the nature of the grist is; furthermore, these results are obtained by
one treatment of the grist.
The apparatus consists of a frame, to which a vertical metal cylinder is fixed,
the whole being secured to a suitable iron stand, so formed that a vertical shaft
driven by belt or bevel gearing can be mounted in same. The pulverizing wheel
or grinder, consisting of cross-arms, and mounted ou said vertical shaft rotates
inside said frame, and is provided with a plate to which arins are attached, carrying
a ring, each of these parts above mentioned, being provided with a number of
radially arranged points, pins, or projections which pass very closely to corresponding
radially-arranged projections in the bottom & walls of said frame, thus successively
effecting the pulverization of the grist.
The grist or corn to be ground is conducted to the mill by a suitable feeding
device, passes through an inlet pipe in the centre of the cylinder, and is delivered
to a receptacle or compartment, in which the wheel or grinder of the disintegrator
rotates, so that it is first acted upon by the projections of the arms of the grinder,
which impart a rotating movement to the grist and a tendency of being thrown
out radially. It then comes in contact with other projections, which pass closely
to corresponding projections in the wall of the frame and impart an axial & upward
movement to the grist.
Projections or points on the under and upper surface of the outer edge of the
horizontal plate, rotate very closely to the walls of the frame provided with
grooves or indentations, against which grooves the meal is thrown by reason of the
great velocity of the grinder and the action of the projections; projections may
also be made in the walls of the frame instead of grooves.
In being forced between the narrow annular space, between the said horizontal
plate, and the walls of the frame, by the subsequent material & in consequence of
the current of air generated by the rapid rotation of the grinder, which acts as
fan, the grist is forced through the whole mill.
By the action of a ring fixed on the grinder, above the said horizontal plate, and
having projections, which pass by similar projections, provided in great number in
the walls of the frame, the grinding process is finished.
During the operation and in consequence of the velocity of the grinder & the
current of air which passes through an opening in the top of the cylinder, the finely
ground meal flies upwards, impinges against the top of the cylinder, and falls into
a funnel fixed inside the cylinder; the finely ground meal is thus collected in
said funnel, from which it is conducted by means of a worm or other suitable
device.
The sufficiently ground meal, therefore, is continually conducted from the mill,
whereas the rougher grist remains until fine enough to be thrown up into the
funnel.
A pipe may be connected with the afore-mentioned opening in the top of the
cylinder, through which finely ground meal, carried with the current of air,
passes into a suitable receptacle; said current may be generated by a fan or
similar device

page_text: A filtering cloth or gauze, may also be placed over said opening to prevent
meal passing through same.
The cylinder and frame in which the grinder rotates, may be wholly or partly
surrounded by a jacket or the like, between which cold water or air circulates
for protecting the mill or meal from injury by heating on account of the velocity
of the grinder.
The operation herein described may be reversed; viz. :-the material may pass
from the top to the bottom of the disintegrator. In this case the corn falls directly
onto the wheel, which, in this case, is not recessed, the projections of the first series
being provided in the cover of the casing.
All the points or projections are preferably of such form which offers the greatest
grinding surface; parallelopiped projections are very advantageous.
The number of projections on the grinder and bottom and walls of the frame
may be varied according to the material to be ground, the degree of fineness
required & the diameter and velocity of the grinder etc.
The frame and stand may be arranged so as to allow of ready access to the grinder
when, required.

Improved Disintegrator or Corn Mill.
I, GUSTAV BINDER of Sennefeldergasse 2 Vienna in the Empire of Austria,
Manufacturer, 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 :-
This invention relates to a disintegrator or corn-mill, and has for its object to
produce a very fine and uniform meal, no matter what the nature of the grist is;
moreover these results are obtained by one single treatment of the grist.
In order that my invention may be clearly understood, I will now describe my
invention with reference to the accompanying drawing, in which:
Fig. 1 is a vertical section of the disintegrator,
Fig. 2 2 and. 2° are horizontal sections on lines a a, b, b, c c of Fig. 1,
Fig. 2 is a plan view of all the parts below the line d d of Fig. 1 and showing
the grinding wheel or grinder as well as the frame-work, after all the upper parts
of the apparatus have been removed;
Fig. 2 is a horizontal section through the frame work and grinder on line e, e of
Fig. 1 (on the same plane as c c) showing at the same time the parts of the frame
work and grinder situated above this section and as seen from underneath;
Fig. 3 is a vertical section. through the upper part of the frame and metal
cylinder of the disintegrator and Fig. 4 a modification of same.
The hub b of the pulverizing-wheel or grinder consisting of cross arms c, c, of one
piece, is mounted on a vertical shaft a driven by belt or bevel gearing; this shaft a
is suitably, mounted in a step-bearing and journal d, above same, the cross arms c, c
carry a sheet metal horizontal circular plate e, above which latter is secured a
ring by means of supports f,fand bolts g, g. The cross-arms c, c, plate e and
ring are provided, with a number of projections pins or points. which agitate,
beat and grind the grist in such manner that a complete pulverization is effected.
The grist or corn to be ground enters the cylinder or receptacle j through the
inclined pipe i, to which it is fed by means of a shaking device, feed-rollers, or
other suitable device, or by a pipe connection . At the lower end of cylinder i,
the grist passes into the space in which the grinder rotates. The grist is first acted

page_text: on by the projections c¹ (1 or 2 in number) of the cross arms c, c which impart the
first rotary motion to the corn and tend to force same out radially; the grist then
comes in contact with the projections or beaters e¹, e, e³, ¹, and is forced upwards
in axial direction. Said projections or beaters pass with considerable velocity
closely to corresponding projections surrounding the walls of that part of the
frame within which the grinder rotates. The bottom K of the frame is also
provided with a series of annularly arranged projections Ki preferably riveted in
said bottom K, their projecting ends being strengthened and kept in position by a
ring K (Fig. 2). The projections el (about 2 in number) rotate past said pins K¹
with the least possible play and thus effect the first grinding of the grist. The
beaters e (about 4) and es (about 6 in number) on the upper and lower faces of
the periphery of plate e rotate very closely to the walls of the frame provided with
grooves or indentations 11, 1
P, P.
against which the grist is
dashed by reason of the great velocity of the grinder, and at the same time must
pass between the faces of the beaters and the ribs between the grooves ', . . also
between the faces of the beaters e and the ribs between the grooves 12, 12, whereupon
the grist is ground.
In consequence therefore of the small, annular space between the plate e of the
grinder and the mantle 1, the constant tendency of the meal to be thrown out
radially against l', ', the generation of air caused by the great velocity of the
grinder, which acts as a fan or ventilator, or the sucking action of a special fan
causing a current of air to pass in an upward direction through the mill, the grist
or corn is forced or carried through the disintegrator.
The projections h¹ (1 or 2 in number) secured to the ring rotate closely to
the beaters m', a large number of which are riveted in the walls of the frame m;
the passage between these latter is the final stage of the pulverizing or grinding
process.
The beaters, projections, pins etc. are preferably of such form and so inclined
that their surfaces afford the greatest possible grinding faces to the grist or corn
passing between or dashed against same; for instance parallelopiped projections
are very suitable.
The ribs between the grooves or of the mantle of the frame, may be
substituted by special noses, ledges pins, beaters or the like secured to the mantle /
and projecting radially into the frame.
The number of projections pins, or the like secured to orted on the various
parts or faces of the grinder, walls etc. may be regulated or varied according to
the material to be ground, the size of the grain or corn, the degree oueness
required, the diameter and velocity of the grinder and the arrangement of such
projections etc. on the walls of the frame.
The cylinder j is secured in the central position against the grinder and against
the annular opening of the plate e, by its connection (by radial arm n) with the
mantle m of the upper part of the frame. The ring c passing closely to the annular
nose K³ during the rotary movement is fixed to the cross-arms c, c and like the
leather-packings and K₁ serves to enclose the inner frame.
On the ring m of the extension of the frame is riveted the sheet-metal cylinder o,
inside of which the pulverized and ground grist is whirled upwards and impinges
against the straight or conical cover p provided with an outlet and then falls
into the open funnel 9. The fine meal thus collected in the funnel q, is constantly
removed away by a worm s rotated in the piper by suitable gear, or by any other
similar device.
As shown in Fig. 3, the pipe t leads from the cover p of the cylinder o into a
dust receptacle in which the fine meal carried along by the current of air can be
allowed to settle and then sorted; the current of air in the pipe t is generated by a
fan or like device.
In the modification shown in Fig. 4 a filtering cloth or gauze u may be stretched
over the opening above the cover p of the cylinder o, by means of which gauze the
air passing into the pipe t is freed from dust as far as possible. This arrangement

page_text: is especially preferable when no special fan is employed for producing the necessary
entrent of air, the current being generated by the grinding wheel of the mill, and
when it is intended to sort the product.
The whole frame k, l, m and sheet metal cylinder resting on same are mounted
on the iron stand v, on which the journal d is cast and in whose lower part the step
bearing for the vertical spindle a is situated.
Frame k, l, m and cylinder o may be surrounded wholly or partly by a jacket or
the like between which cold water or air circulates, for protecting the mill or meal
from injury by heating on account of the velocity of the grinder.
Finally the bottom or stand of the frame k, I may consist of door-like hinged
parts to allow ready access to the grinding wheel and to the inner parts of the
frame etc.
In that case the stand of the frame is provided with two walls,
(Fig. 24 and 2º) on which the moveable walls, are secured by means of vertical
hinges, y; these walls, being held in their central position by adjustable
bolts yy. The part m of the frame then rests on the fixed side walls, also
when the doors of the stand are open. By this arrangement it is also possible to
secure the end of the radial and inwardly directed projections m' in the opening
walls of the frame instead of in the part m; the adjustment and raising of the
grinder when required is thereby readily effected.
It will be evident that instead of the grist passing from the bottom to the top of
the disintegrator, as shown in the drawings, it may be made to pass from the top
to the bottom. In that case the grist passing through the feed opening falls
directly on to the disc of the grinding wheel and the annularly arranged series of
projections would be riveted in the cover or top of the casing."
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 1
claim, is:
1. Improved disintegrator or corn-mill, in which the grinder mounted on a
vertical shaft and provided with projections (pins, pegs, points, beaters etc.)
rotates in a frame likewise provided with corresponding projections, the ground
neal being made to whirl upwards into a cylindrical extension (o) by reason of
the current of air generated owing to the great rotary velocity of the grinder, or
by means of a specially-arranged fan, the heavy, insufficiently treated particles of
meal being deflected against the under face of a centrally-arranged funnel (g)
and falling back again into the mill for further treatment, only the finely
reduced meal being thus carried by the current of air above the upper edge of
said funnel (q) into which latter it falls either directly, or after having impinged
against the cover (p) substantially as described and shown in the drawings.
2. In a disintegrator or corn-mill as described in Claim 1 the annular or radial
arrangement of a number of projections (pins, pegs, or the like) in the faces of the
various parts (arms c, plate e, ring h etc.) constituting the grinder and in the walls
of the frame, such projections passing as closely as possible to each other and
effecting a fine and uniform grinding of the grist or corn, substantially as described
and shown in the drawing.
3. A disintegrator or corn-mill, as described in Claims 1 and 2, in which the
grist or corn is automatically fed to the mill through inlet-pipe (i) and, after
passing through the mill and being sufficiently ground, is carried upward by the
current of air, dashed against the cover (7) and deflected into the funnel (g) from
which it is removed or carried away by a worm or other suitable transmitting
device, the operation of the mill being thus continuous, substantially as described
and shown in the drawings.
4. A modification of the disintegrator or corn-mill described in Claims 1, 2 and 3,
the arrangement of door-like hinged parts underneath the frame for allowing ready
access to the grinder etc. substantially as described and shown in the drawing.
5. A modification of the disintegrator or corn-mill described in the foregoing
claims, the arrangement of a jacket wholly or partly surrounding the frame adapted

page_text: to receive cold water or air to prevent the mill, or the meal being injured by the
heat generated by the rapidly rotating grinder, substantially as described and
shown in the drawing.
