page_text: THO WEST, Engineer Bromley Engine Works 144 Devon's Road Bromley
by Bow London Middlesex do hereby declare the nature of my invention for
IMPROVEMENTS IN MACHINERY AND APPARATUS FOR MILLING, DECORTICATING
AND SCOURING RICE, PEPPER, BARLEY, AND OTHER GRAINS, AND SEEDS to be as
follows-
My invention and improvement relates to machinery and apparatus for milling,
decorticating and scouring rice pepper, barley, and other grains and seeds :-
whereby I am enabled to rapidly and uniformly decorticate and scour the grains
and seeds with very little breakage, and at the same time taking less power than
those usually adopted for the same purpose. For this purpose I employ a combined
cylindrical and conical drum either composed of a natural stone or an emery
composition so as to obtain a keen or sharp surface for scouring the grains and
seeds. This drum is fixed on an upright steel shaft to which is attached a double
flange pulley same being driven by means of a half twisted belt, so as to entirely
dispense with gearing, the said drum revolving within a perforated or plain
cylindrical case or barrel which is made to revolve slowly in the same direction
or otherwise by means of a wheel and pinion driven by pullies as to be herein after
described; the case or barrel is larger inside than the outside diameter of the said
combined cylindrical and conical drum and which requires no adjustment, the
interstitial space between same being sufficient to contain the grains and seeds so
as to intermix one with another thereby causing sufficient friction to scour and
decorticate same.
The regulation of the outlet of the grains and seeds which are first of all
delivered into the top of the machine so that the machine is always full, is
arranged by means of a self acting joggler adjusted to suit the spout or delivery
passage fixed to the lower part of the machine as follows:-a joggler motion is so
arranged that it comes in close contact with the mouth of the spout, and is
regulated by means of an adjusting screw as desired by the operator, same is
joggled by employing a cam on a revolving shaft which is driven by pullies from
the upright shaft of the said drum, a loose plate is also fixed to the joggler so that
the operator can if required pull same away sufficiently for the hand to be put up
the spout should same at any time become foul with a peice of bagging or any
[Price fid

page_text: other extraneous matter, and can also by the use of this loose plate entirely empty
the machino if required.
The means employed to slowly revolve the perforated case or barrel are a
follows on the upright steel shaft of the machino is fixed a pulley which
transmits power to two seperate countershafts, to one of which is fixed a bovel
pinion geared into a bevel wheel attached to a small upright spindle on which
is fixed a small spur pinion geared into a spur wheel attached to the revolving case
or barrel, and on one of the said countershafts is fixed a cam which gives the
recipricating motion to the above said joggler.
I also employ wrot iron (stationary) scrapers so arranged as to come into close
contact with the said revolving case or barrel; and by these means employed I am
enabled to keep the machine free from meal and at the same time to provent any
clogging.
By this improvement I am enabled to disponse with a number of working parts
so as to reduce friction and wear and tear to a minimum: the several parts of the
machine are made in duplicate, and with the mechanical arrangements employed
I am enabled to manufacture the machines accurately and at the same time
economically.
It is obvious that by this apparatus for milling decorticating and scouring rice,
pepper, barley and other grains and seeds, that by employing these small machines,
I am enabled to turn out a bolder sample with less breakage, and taking less power
to turn out a given quantity in the least time, and I also claim an advantage by
employing a quantity of these small machines, that in case of a breakdown with
any one of them the whole or greater part of the mill is not stopped as in the case
of employing the usual large machines.

hereby declare the nature of my invention for IMPROVEMENTS IN MACHINERY

BARLEY AND OTHER GRAINS AND SEEDS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:

The regulation of the outlet of the grains and seeds which are first of all

shafts is fixed a cam which gives the recipricating motion to the above said joggler.
I also employ wrot iron stationary scrapers arranged so as to come into close contact

revolving case or barrel and set at equidistances between the cylindrical and conical
drum and bottom plate by theso means employed I am enabled to keep the machine

ment I am able to dispense with a number of working parts so as to reduce
friction, and wear and tear to a minimum: the several parts of the machine are

I am enabled to turn out a bolder sample with loss breakage and taking less power
to turn out a given quantity in the least time, and I also claim an advantage by
employing a quantity of these small machines that in case of a break down with
any one of them, the whole or greater part of the mill is not stopped as in the case
of employing the usual large machines. In order that my invention may be more
fully and clearly understood, I will horewith aided by the accompanying drawings
describe the same.

Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare what
I claim is
1 The top plate C bolted to frame sides, with projection or ring on the
underneath side lettered u which is covered with an emery composition, also the
bottom plate D with cone and spout, same being bolted to frame sides as shown.
2 The combined cylindrical and conical drum H either composed of a natural
stone or emery composition, and fitted to the steel shaft with a cast iron boss and
fixed by means of an hollow key and stop pin so that same can be readily removed
when worn out & replaced with another drum, same revolving in a plain or
perforated case or barrel K which may be raised or lowered as may be required by
means of an adjusting screw underneath foot plate E as shewn, also the perforated
case or barrel revolving slowly in the opposite direction or otherwise.
3 The application of the joggler F with a sheet iron slide or loose plate and
screw r, and connecting rod & joint p with screwed ends for the purpose of
adjusting and regulating the feed, the same being automatically joggled by means
of cam 8 driven by the countershafts & pullies as herein before described.
4 The wrot iron stationary scrapers 7 fixed to top bracket C in close contact to
side of revolving case or barrel K, also three or more wrot iron arms fixed to the
revolving case or barrel and attached together by a circular plate or ring same
bored to fit upright shaft G loosely to keep same equidistant from the drum H and
bottom plate D for the purpose of keeping the machine clear and to prevent the
clogging of meal.
In witness whereof I. the said Thomas West. have hereunto set my hand and
