IMPROVEMENTS IN APPLYING MOTIVE POWER FOR GRINDING CORK AND FOR STEED SIMILAR PROD "
Year: 1855

page_text: LETTERS PATENT to Edward George Swinton, of Warsash House, near
Titchfield, Hampshire, a Captain in Her Majesty's 8rd Light Dragoons,
for the Invention of "IMPROVEMENTS IN APPLYING MOTIVE POWER FOR
GRINDING CORK AND FOR STEED SIMILAR PROD
"
PROVISIONAL SPECIFICATION left by the said Edward George Swinton
at the Office of the Commissioners of Patents, with his Petition, on the
28th May 1855.
I, EDWARD GEORGE SWINTON, of Warsash House, near Titchfield, Hamp-
shire, a Captain in Her Majesty's 3rd Light Dragoons, and now on half pay,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPLYING MOTIVE POWER FOR GRINDING CORN, AND FOR OTHER SIMILAR PURPOSES,"
to be as follows:-
The peculiar feature of novelty of this Invention consists in adapting the
rotary movement of the wheels of a cart or other similar vehicle to ordinary
machinery placed therein, suitable for grinding corn, bruising oats, or other
similar purposes; and although the said improvements are designed more par-
ticularly for the use of the army, as affording a cheap and available method
of effecting the above objects, at the same time I do not intend to limit or
confine myself to such particular use, as they are equally applicable to civil

page_text: purposes, and will in many cases be found more desirable and cheaper than
the stationary machinery heretofore commonly employed for such purposes.
The nature of these improvements will, however, be better understood by the
following description of the means by which they may be carried into practical
effect, that is to say:-Upon one or both of the naves or boxes of the wheels
of a cart I securely fix a spur wheel, bevil wheel, or pinion, which takes into
a corresponding wheel or pinion of the grinding machinery employed, said
wheel or pinion being of suitable size, according to the speed at which it is
required to drive such machinery. The above-mentioned wheel may either be
fixed upon the axis of the grinding cylinder or cone, or other grinding medium,
or there may be a train of intermediate wheels between the prime moving
wheel and the wheel which is upon the axis of the grinding cylinder, &c.
We would here remark, that as the grinding or bruising machinery to be
employed forms no part of this Invention, but is such as is commonly used for
such purposes, and is well known, it is therefore unnecessary here to enter into
any detailed description thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward George Swinton in the Great Seal Patent Office on
the 28th November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
GEORGE SWINTON, of Warsash House, near Titchfield, Hampshire, a Captain in
Her Majesty's 3rd Light Dragoons, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of May, in the year of our
Lord One thousand eight hundred and fifty-five, in the eighteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Edward George Swinton, Her special license that I, the said
Swinton, my executors, administrators, and assigns, or such
others as I, the said Edward George Swinton, my executors, a
and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN APPLYING MOTIVE POWER FOR GRINDING CORN, AND FOR
OTHER SIMILAR PURPOSES," upon the condition (amongst others) that I the said

page_text: Edward George Swinton, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to bo 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 Edward George Swinton, 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, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say) :—
This Invention relates to the economic use of motive power derived from
beasts of burden while employed in drawing from one place to another a load
of corn or other substance requiring to be ground or crushed. For this purpose
I mount in the cart which is to receive the load suitable crushing or grinding
apparatus (according to the produce to be carted), and by means of suitable
driving gear I transmit rotary motion thereto from the running wheels of the
cart. If, therefore, during the journey the crushing or grinding surfaces are
properly supplied with grain or other seed, they will reduce it to flour or crush
it merely, as the case may be, whereby a great saving of time will be effected,
and the necessity of setting up stationary mills to operate upon the carted
produce will be avoided.
In the accompanying Drawing, Fig. 1 is a hind elevation of a cart pro-
vided with two sets of grinding or crushing apparatus; Fig. 2 is a sectional
elevation, taken in the line 1, 2, of Fig. 1; and Fig. 3 is a plan view, with
the hoppers removed. a, a, is the framing of the cart, which is mounted on
running wheels b, b. To these wheels are connected the cog wheels c, c, which
severally drive a pinion e, keyed to the axle d of the crushing wheel ƒ of
each mill. This axle runs in suitable bearings formed in the metal frames g,
which are firmly secured to the frame of the cart. h is a second crushing
wheel carried by an axle i, which also has its bearings in the metal franc g.
The grain or other substance to be operated upon is conducted from a
hopper & by a spout or shute 1, to the space between the rollers f and h, where
it is reduced by the rolling pressure of the crushing surfaces to small pieces,
or (if toothed or ribbed grinding surfaces are used) ground to powder. The
supply of the grain to the crushing surfaces is regulated by a sliding plate l
and a cup roller m set in the shute 7, and receiving rotary motion from the
smaller crushing roller (which is itself driven by friction of contact) by means
of the gearing n, n.
When a grinding action is to be performed, I prefer to employ a fixed con-

page_text: cave toothed case in place of the roller h, as indicated by the Diagram, Fig. 4.
The pulverized or crushed material is guided by an inclined plate o to an
open sack, suspended from the cart tail, and partially supported by a pendent
shoe p.
When the sack is full it is removed by the attendant and replaced
by an empty sack. Provision is made at the fore part of the cart for carrying
the seed or other substance to be operated upon, and it is transferred from
time to time to the hoppers by the attendant, a clear space in the body of the
cart being provided to facilitate his operations.
From the above description it will be obvious that this arrangement of
apparatus will be particularly applicable for following the movements of a
marcbing army; but other useful applications of the apparatus will also readily
suggest themselves, and that chiefly in connection with' the treatment and
supply of agricultural produce.
As respects the arrangement of the body of the cart for the reception of
I the ground and unground material, I may remark that it may be varied to
suit varying circumstances, and likewise that the crushing surfaces may be
smooth, as shewn in the Drawing, or ribbed or toothed; or millstones may
be used, according to the substance intended to be operated upon; and also that
one of the crushing surfaces should be rendered capable of adjustment, in
order to accommodate the apparatus to its work.
Having now described my Invention of "Improvements in applying Motive
Power for Grinding Corn, and for other similar Purposes," I wish it to be
understood that, under the above in part recited Letters Patent, I claim the
application to carts or other like vehicles of grinding or crushing apparatus,
and the driving of the same by rotary motion derived from the running wheels.
In witness whereof, I, the said Edward George Swinton, have hereunto
set my hand and seal, the Eleventh day of September, in the year of
our Lord One thousand eight hundred and fifty-five.
