Year: 1864

page_text: LETTERS PATENT to Robert Maynard. of Whittlesford, in the County
of Cambridge, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
PROVISIONAL SPECIFICATION left by the said Robert Maynard at the
Office of the Commissioners of Patents, with his Petition, on the
29th November 1864.
I, ROBERT MAYNARD, of Whittlesford, in the County of Cambridge, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
FOR CUTTING, SEPARATING. GRINDING, AND CRUSHING AGRICULTURAL PRODUCE," to be
as follows:-
This Invention relates to improvements upon a certain Invention for which
Letters Patent were granted to me on or about the Third day of March, One
thousand eight hundred, and fifty-six, No. 358, for "Improvements in
Machinery for Cutting and Separating Agricultural Produce," and to such
machines only as are therein described as portable chaff engines, and as are
fitted with a riddle for separating the imperfectly cut from the perfectly cut
chaff.
The present improvements consist in using in combination with such chaff
engines a millstone, a roller, or other apparatus suitable for grinding or
crushing corn, grain, oil cake, or other agricultural produce, so that the
[Price 8d.]

page_text: operations of cutting, grinding, or crushing may be performed at the same
time.
Second, in using in combination with such chaff engines an endless webb.
or chain, furnished with spikes or buckets, and passing over a revolving drum
or any other apparatus which in practice I may find suitable for carrying up
straw or other material to the height necessary to operate upon it.
SPECIFICATION
in pursuance of the conditions of the Letters Patent, fled
by the said Robert Maynard in the Great Seal Patent Office on the
22nd April 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I. ROBERT
MAYNARD, of Whittlesford, in the County of Cambridge, send greeting,
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of November, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did. for Herself. Her beirs and successors, given and grant unto
me. the said Robert Maynard. Her special licence that I, the said Robert
Maynard, my executors. administrators, and assigns, or such others as 1,
the said Robert Maynard. my executors, administrators. 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 Invention for
"IMPROVEMENTS IN MACHINERY FOR CUTTING, SEPARATING, GRINDING, AND
CRUSHING AGRICULTURAL PRODUCE," upon the conditions (amongst others)
that I, the said Robert Maynard, my executors or administrators. by an
instrument in writing under my, or their, or one of their hands and seals.
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be 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 1, the said Robert Maynard, 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 improvements upon a certain Invention for which
Letters Patent were granted to me, on or about the Third day of March, One

page_text: thousand eight hundred and fifty-six, No. 358, for "Improvements in
Machinery for Cutting and Separating Agricultural Produce," and consists,
first, in combining with such machines as are described in the Specification of
that Patent as portable chaff engines." and as are fitted with the second
improvement therein described, namely, a "riddle for separating the chaff from
the cavings or short straws," apparatus for grinding or crushing agricultural
produce, so that the operations of cutting and sifting and of grinding or
crushing may be carried on simultaneously in the same machine.
And, second, in combining in such machines apparatus for elevating the
straw or other substance to be operated upon to a convenient height, for the
purpose of being fed to the cutting, grinding, or crushing apparatus.
In order that the said Invention may be fully understood. 1 shall now
proceed particularly to describe the same, reference being made to the Sheet
of Drawings hereunto annexed, the same letters of reference indicating
corresponding parts throughout all the Figures.
Fig. represents an end view of a portable chaff engine fitted with a' riddle
and with the parts suitable for the accomplishment of the purpose set forth in
the foregoing statement; Fig. 2 is a side view of the same, A being the
trongh wherein straw. hay, or other material to be cut into chaff is laid, which
is drawn forward by rollers, and cut by the knives which revolve in the case B,
whence the chaff descends into the riddle C, which separates the perfectly
from the imperfectly cut chaff or cavings. D is a rigger keyed on the end of
the shaft E, which carries the knives; and F is a rigger keyed on the end of
a shaft carrying a tapered grooved roller G and a toothed roller II. The
roller G revolves within a conical spirally grooved case I, and corn or grain
being supplied to the same by the spout J, it is ground to meal in its passage
through, and is delivered by the spout. K. The hopper contains a plate O
with notches in the lower end of it, which fit between the teeth of the
roller II, and oil cake being supplied to the hopper, it is acted upon by the
teeth and the roller, and broken or ground to any desirable size, passing out
at the spout M. The riggers D and F are connected by a band. over which a
band from the driving power is passed, thereby communicating motion to the
several parts described; or the band from the driving power may be passed
over either of these riggers separately when all the operations are not required
to be carried on at the same time. N represents the end view of a curved
board; P, P. are drums, over and under which is passed the endless chain Q,
carrying the spikes R. Motion is communicated to the drums by suitable
gearing leading from the shaft E, and straw or other material requiring to be
elevated is laid on the lower part of the incline, and carried by the spikes R

page_text: to the platform S. ready to be operated upon by the machinery already
described; or, instead of the board and endless chain. I use the apparatus
shewn in Fig. 3 and 4, Fig. 3 being an end view, and Fig. 4 a side view of
the same. T is a cradle carried by the radial arms U, U, working on the
rocking spindle V; Y is a crank caused to revolve by suitable gearing
connecting its spindle with the shaft E; it carries the thimble W. to which is
attached one end of the strap X, the other end of which strap is passed round
and made fast to the rigger Z, which rigger is keyed on the spindle (a). On
the spindle (a) are also keyed two other riggers b, b, each having one end of a
strap c', c, attached to it, the other end of each of these straps being attached
by the loops d, d, to the arms of the cradle U, U. Straw or other material being
placed on the cradle it is obvious that the crank Y revolving the strap X
causes the rigger Z and b, b, to revolve till it arrives at its lowest dead point,
and the straps c, c, coiling round their riggers b, b, the cradle ascends till it
arrives in the position shewn by the dotted lines delivering the material on to
the platform. The crank continuing to revolve, the cradle descends to its
former position again.
Having thus described the method I take of combining together in one
machine apparatus for cutting, riddling, grinding, and crushing, and the
apparatus use for elevating. I wish it to be understood that I do not lay
claim to as being of my Invention all the parts herein described, nor to the
use of either of such parts separately, nor do I claim the use of such parts in
combination with any machine that is not provided with a riddle for separating
the chaff from the cavings, and described as a portable chaff engine in the
Specification of the former Letters Patent, to which reference has been
made.
I also wish it to be understood that although I have thus described the
apparatus use to accomplish the object I have stated, I do not confine
myself to the precise details or arrangements I have had occasion to describe,
as many variations may be made therefrom without deviating from the
principles or main features of my said Invention, nor do I confine myself to
the same kind of apparatus for crushing, grinding, or elevating, as in practice
other more efficient means for effecting the same respective purposes may be
found; but what I do claim is,-
First, in using in combination with a portable chaff engine, the same being
fitted with a riddle for separating the chaff from the cavings. a roller, a
millstone, or any apparatus for grinding or crushing corn, oil cake, or other
agricultural produce.
Second, in using in combination with the same described machine apparatus

page_text: to elevate the straw or other agricultural produce to a convenient height
before being operated upon by the cutting, grinding, or crushing apparatus.
It witness whereof, I, the said Robert Maynard, have hereunto set my
hand and seal, the Twenty-second day of April, One thousand eight
hundred and sixty-five.
ROBERT MAYNARD. (L..S.)
