IMPROVEMENTS IN DAGING MAGENES DADE OF WRITTANY
Year: 1860

page_text: LETTERS PATENT to Thomas Woodhouse Ashby, of Stamford, in the
County of Lincoln, Agricultural Implement Maker, and John Coulson,
also of Stamford, Engineer, for the Invention of "IMPROVEMENTS IN
DAGING MAGENES DADE OF WRITTANY τα
PROVISIONAL SPECIFICATION left by the said Thomas Woodhouse
Ashby and John Coulson, at the Office of the Commissioners of Patents,
with their Petition, on the 5th March 1860.
J
We, THOMAS WOODHOUSE ASHBY, of Stamford, in the County of Lincoln,
Agricultural Implement Maker, and JOHN COULSON, also of Stamford, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THRASHING MACHINES, PART OF WHICH IS APPLICABLE TO CRANKS," to be as
follows:-
Our Invention refers to the beaters and screens, roofs or concaves, in which
the drums carrying the beaters revolve, and to the crank on the shaft for
imparting the shaking motion to the shakers of thrashing machines, also to
cranks in general.
We form the surface of the beaters carried on the drum in thrashing
machines of a series of wires or plates, cach bent, cast, or made in the form
of a segment of a circle and set at an angle with the axis of the drum, the
direction of the wires in every alternate beater on the drum is reversed, that

page_text: is to say, if it is from left to right in one beater, it is from right to left in the
next, and so on. The screens or concaves are composed of a frame or series
of frames of wood or other material carrying alternately beating surfaces and
straight wires; these beating surfaces are similar to those on the drum; but the
lower parts thereof may be closed or solid, the wires in the last beater in the
series are not inclined. In some instances we find it well to cut the beforo
named wires or plates forming the beating surfaces in two, and use one half
only. We also form our beaters by attaching arms to the beater carriers on
the drum, which we cause to project and to act as springs; the face of our
spring beaters is vandyked, and between every V in the vandyke there is a
slot; the screen is formed as first described. Again we make our beater
carriers in the form of a flat bar carrying uprights in which are bearings for
a rod or tube, which is clothed with wire cloth.
Our improvement in the crank consists in preventing undue wear thereof
by covering it with a case of hardened steel or other like suitablo matorial
formed in two halves or parts and secured to the crank by screw collars or
other suitable means, so that when the case becomes worn we are enabled to
shift it round and expose a fresh surface.
:
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Woodhouse Ashby and John Coulson, in the Great
Seal Patent Office on the 5th September 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
WOODHOUSE ASиBY, of Stamford, in the County of Lincoln, Agricultural
Implement Maker, and JOHN COULSON, also of Stamford, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of March, in the year of onr Lord One
thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Woodhouse Ashby and John Coulson, Her special licence
that we the said Thomas Woodhouse Ashby and John Coulson, our executors,
administrators, and assigns, or such others as we, the said Thomas Wood-
house Ashby and John Coulson, our 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

page_text: Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN THRASHING MACHINES, PART OF WHICH IS APPLICABLE TO
CRANKS," upon the condition (amongst others) that we, the said Thomas
Woodhouse Ashby and John Coulson, or one of us, our executors or adminis-
trators, by an instrument in writing under our or one of our, 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 we, tho said Thomas Woodhouse Ashby and John
Coulson, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement thereof, reference being had
to the Drawings hereunto annexed, that is to say:-
Our Invention refers to the beaters and screens, roofs, or concaves in which
the drums.carrying the beaters revolve, and to the crank on the shaft for
imparting the shaking motion to the shakers of thrashing machines, also to
cranks in general.
We form the surface of the beaters carried on the drum in thrashing machines
of a series of wires or plates, each bent, cast, or made in the form of a segment
of a circle or staple, and set at an angle with the axis of the drum; the direc-
tion of the wires in every alternate beater on the drum is reversed, that is to
say, if it is from left to right on one beater it is from right to left in the next,
and so on.
In some instances we find it well to cut the before-named staples
and plates forming the beating surfaces in two, and use one half only. Wo
also form our beaters by attaching arms to the beater carriers on the drum,
which we cause to project and to act as springs; the face of our spring beaters
is vandyked, and between every V in the vandyke there is a slot; the screen
is formed to suit these vandyke beaters, like that hereafter described. Again,
we make our beater carriers in the form of a flat bar carrying uprights, in
which are bearings for a rod or tube, which is clothed with wire cloth. The
screens or concaves are composed of a series of frames of wood, carrying alter-
nately projecting perforated plates or surfaces and straight bars; the projecting
parts are similar to those on the drum, but the lower parts thereof may be
closed or solid; the first plate is rounded off at the lip, and the projections in
the last plate in the series are not inclined.
.Our improvement in the crank consists in preventing undue wear thereof by
covering it with a case of hardened steel, or other like suitable material,

page_text: fornied in two halves, and secured to the crank by screw collars, or otherwise ;
when the case becomes worn we shift it round and expose a fresh surface.
.
Figure 1 of the accompanying Drawings is a plan, and Figure 2 a side cle-
vation, of one form of beater, constructed according to our Invention. a is the
beater plate, carrying segments b, b, each segment running in a diagonal direc-
tion to the beater plate, and parallel, or nearly so, to one another. These
beater plates are fixed to the thrashing drum, and set, as before stated, at an
angle to the axis thereof. The beater plates are made flat, as shown in the
Drawing, or the plates may be made of an oval shape. The grain passes
through the longitudinal passage marked c, formed by the segments b, b.
Figure 3 is a plan, and Figure 4 a side elevation, of another form of beater,
being similar to the beater just described cut in half through the beater plate
and segments. a is the beater plate as before; b, b, are the segments or half
bows. Figure 5 is a plan view of one of our spring beaters. d, d, are the
vandyked faces; e is the slot formed between the faces.
Figure 6 is a plan, and Figure 7 an end view, of one of the projecting sur-
faces or perforated plates, which we attach to the screens or concaves of
thrashing machines alternately with straight bars or with perforated plates.
That part most exposed to the grain is made round or oval, so that the grain
may pass through without being damaged.
Figure 8 is a plan of a similar projecting surface, in which the segments or
projecting surfaces run in a diagonal direction. Figure 9 is an end view, and
Figure 10 a face view, of part of a concave or screen fitted with these project-
ing surfaces and straight bars; the projecting surfaces are arranged alternately
with the straight bars, as shown in the Drawing. Figure 11 is a plan, and
Figure 12 an end view, of bearings or shields we fit to the cranks of thrashing
machines, and to cranks in general. a, à, are the bearings or shields, formed
of hardened steel, or other suitable metal. These shields formed in two halves
surround the crank, and are secured to it by clamps or clips b, b. The clamps
are held by means of screw bolts c, c, as shown. Figure 18 is a plan, and
Figure 14 an end view, of similar bearings or shields, having the clamps or
clips formed in a piece with them. In this case the bearings or shields are
secured to the crank by four screw bolts passing through the lugs d, d, d, d,
instead of by two bolts, as in the former case.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim,-
First, constructing the surfaces of beaters used in thrashing machines of a
series of wires or plates, each bent, cast, or made in the form of a segment of
a circle, or in the form of a staple, and set at an angle with the axis of the

page_text: drum, as herein-before described and illustrated at Figures 1 and 2 of the
accompanying Drawings.
Second, the forming of the surfaces of beaters in thrashing machines of half
segments or bows, as herein-before described and illustrated at Figures 3 and 4
of the accompanying Drawings.
Third, the construction of spring beaters of a vandyke form, slotted between
each vandyke, as herein-before described and illustrated at Figure 5 of the
accompanying Drawings.
Fourth, covering the surfaces of beaters used in thrashing machines with
metallic cloth, woven wire, or other suitable material, as herein-before
described.
Fifth, constructing concave screens or roofs for thrashing machines of a
series of frames carrying alternately projecting surfaces or perforated plates
and straight bars, as herein-before described and illustrated in the accom-
panying Drawings.
Sixth, the construction of cranks used in thrashing machines and cranks in
general, by covering them with a case of hardened steel, or other like suitable
material, in the manner and for the purposes herein-before described and
illustrated in the accompanying Drawings.
In witness whereof, I, the said John Coulson, have hereunto set my
hand and seal, this Fourth day of September, One thousand eight
hundred and sixty.
Witness,
WILLIAM JONES,
Stamford.
JOHN COULSON. (L.S.)
