PROVISIONAL SPECIFICATION left by the said James Hayes, the elder,
Josiah Hayes, and James Hayes, the younger, at the Office of the Com-
missioners of Patents, with their Petition; on the 16th April 1866.
We, JAMES HAYES, the elder, and JOSIAH HAYES, of Elton, in the County of
Huntingdon, Machine Makers, and JAMES HAYES, the younger, of War-
mingtou, in the County of Northampton, Miller, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
SHAKING, RIDDLING, RAISING, AND DELIVERING STRAW, HAY, CORN, AND OTHER LIKE
AGRICULTURAL PRODUCE, AND IN THE MODE OF DRIVING OR TRANSMITTING MOTION
THERETO, PARTS OF WHICH IMPROVEMENTS ARE APPLICABLE TO THE DRIVING OR
TRANSMITTING OF MOTION TO OTHER MACHINERY," to be as follows:-
This Invention relates to a peculiar construction, arrangement, and com-
bination of machinery or apparatus for shaking; riddling, raising, and

page_text: delivering straw, hay, corn, and other like agricultural produce, and to a
mode or modes of driving or actuating the same, which apparatus may either
be mounted upon running wheels of its own and form an independant straw
shaker and elevator, or may be combined or framed in with a combined
thrashing machine, either fixed or portable, so as to form the straw shaking
and elevating mechanism of such machine.
In carrying out our Invention we propose to combine a set of straw shakers
either of the ordinary construction, or of the peculiar construction herein-after
described, with endless chains, or bands, or webs carrying connecting bars
provided with teeth, tines, or projections travelling along a trough or frame
capable of being adjusted to any desired height or vertical angle by the aid of
rack and pinion gear or otherwise, whereby the straw will be simultaneously
sbaken and elevated, or delivered on to the stack. When constituting an
independent machine the various elements above referred to will be all
mounted upon and carried by a frame or carriage provided with running
wheels for the facility of transport; but when such elements are to be com-
bined with or form.-part of. what is known as a "combined thrashing
machine," then the separate carriage or. frame may be dispensed with, as the
framing of the thrashing machine itself will form the support for the shaking
and elevating mechanism. When constructed as an independent machine the
combined straw shaker, elevator, and riddle will consist of an inclined trough
centred or pivotted at its lower end upon the first-motioned shaft of the
machine. This shaft is carried in bearings on the main framing, which is
provided with running wheels for the facility of transport. The trough is
capable of adjustment to the desired height or vertical angle by having racks
attached thereto, into which gear spur pinions actuated by a worm or end-
less screw supported on the fore part of the main framing. The lower end of
the trough contains a set of straw shakers, which may be of the ordinary kind,
but we prefer to adopt the peculiar construction herein-after described. Our
improved shakers are made to vibrate in a vertical plane only, and have no
forward throw whatever, as the travelling motion of the teeth, tines, or pro-
jections carried by the connecting bars of the endless chains serves to movo
the straw along the surface of the shakers. Each shaker vibrates vertically
upon a fixed hinge pin at its higher extremity, and in order to allow of the
sbaker's rising and falling in a parallel manner we insert a hinge joint therein
a short distance from the upper fixed end of the shaker, the portion comprised
between the two binges acting as a link. The vibrating motion of the shakers
is obtained by connecting the under side of each shaker by means of links
with two vibrating arms or quadrants carried by two rocking shafts supported

page_text: in bearings attached to the trough. These shafts derive their rocking motion
from a crank on a second-motion shaft, which is driven by a pinion from the
driving shaft. The rocking motion of one shaft is transmitted to the other by.
means of a coupling rod, which connects two lever arms keyed on to the two
.shafts respectively. The endless chains, bands, or webs which carry the con--
necting bars containing the teeth, tines, or projections are supported on flat-.
sided pulleys carried on the driving shaft at the lower end of the trough and,
on a carrier shaft running freely in bearings at the top end of the trough, and.
and as the teeth, tines, or projections' travel up the trough they carry along
with them the straw which is placed or made to fall in the lower end of such
trough, causing it move along the surface of the shakers and to be finally
raised to the top of the stack or other elevated position. The teeth, tines, or
projections are caused to travel along the intervening spaces between the
shakers, so that the latter have free play vertically without interfering or
coming in contact with the tines or projections. As in some cases it: may be
found desirable that the travelling motion of the straw whilst it is passing'
over the shakers should be slower than is requisite when it is being simply.
elevated along the trough, we propose sometimes to use a second system of
endless chains or webs, bands, and tines carrying connecting bars or pro-
jections; such second system of endless chains, bands, or webs extending only
over or under the shakers, and being driven at a slower speed than the endless
chains, bands, or webs which carry the straw to the top of the trough when the
shaking and elevating machine is combined with a combined thrashing
machine; then' the endless chains, bands, or webs may be situate underneath
the shakers, the teeth, tines, or projections which travel between the shakers
being made in that case sufficiently long to project above the surface of such
shakers, so as to carry the straw along the shakers to their upper ends, whence
the straw may be elevated in the usual manner. The corn and chaff as they
leave the shaker boxes' fall on to a horizontal flat screen, which vibrates in a
circular horizontal direction upon a vertical fixed pin or pivot, such vibrating
motion being imparted to the screen by a link and lever arm worked by one
of the rocking shafts above referred to. The screened corn is discharged
from the side of the screen by an inclined spout for that purpose attached to
the under side of the screen, and as it falls from this spout a blast of air from
a fan blower is driven through it so as to carry off any chaff or light particles.
When forming part of a combined thrashing machine this apparatus will
enable the straw to be shaken and elevated direct on to the stack as fast as it
leaves the beaters. When so employed the peculiar screen, above described,
may be dispensed-with, and the corn and chaff may pass off from the shaking

page_text: In order to
enable the machine herein-before described, or the combined thrashing
machine of which the improved combined shaking and elevating mechanism
may form a part, to be driven at any desired angle with the shaft of the prime
mover we propose to employ certain peculiar arrangements, herein-after
described, of adjustable driving gear, which arrangements are equally
applicable to the driving or actuating of other machines under similar
boxes and be riddled and separated in the ordinary manner.
circumstances.
According to one arrangement of driving gear we combine a spur pinion.
carried on a shaft on which is fitted a driving pulley, such shaft working in a
pedestal, which is adjustable to any desired angle with a peculiar toothed:
wheel, which is keyed on the first-motion shaft of the combined straw shaker
and elevator, or such adjustable apparatus may be fixed to the combined
thrashing machine, or other machine to be driven. This wheel in lieu of
having the usual spur teeth formed thereon has teeth of a circular, oval, or
rounded contour when viewed on the face of the tooth, or in a direction at
right angles to the axis of the wheel, and these teeth are caused to overhang
or project beyond the face or faces. of the wheel itself, so as to present a
toothed surface not only at the external and internal periphery of the wheel,
but at any intermediate angle. By making the pedestal bearing of the pinion
austalle in a circular direction, the pinion may be caused to gear with the.
teeth of the wheel in any position through many degrees of a circle, thereby
combining in. one arrangement the properties of face gearing external and
internal, spur gearing, and bevel gearing, the motion in all positions being.
transmitted in a direct manner through the gearing. When used as internal
spur gearing the actuating pinion should be changed for one of smaller pitch.
In some cases, if desired, the peculiar toothed wheel may be the driving
wheel, and the pinion the driven wheel, and the bearings of the shaft
carrying the toothed wheel may be made adjustable in the same manner as
the bearing of the pinion in the first instance; or in lieu of a spur pinion
carried on the adjustable driving shaft a bevel or mitre wheel may be keyed
thereon, and inade to gear into a bevel wheel fast on a second shaft which
carries another bevel wheel in gear with a bevel wheel on the first-motion
shaft of the machine to be actuated. This apparatus when required may be
fixed to a convenient part of the combined thrashing machine. By making
the plummer block of the shaft which carries the first bevel wheel or pinion
adjustable to any position concentrically round the second shaft it will be
obvious that the driving pulley may be placed at any angle with the machine,
and thereby enable it to be driven at any angle with the prime mover; or in

page_text: lieu of using toothed gearing a grooved band pulley.may be fitted to the shaft,
the pedestal of which is made adjustable to any angle, and the motion from
such pulley may be transmitted to a corresponding pulley on the first-motion
shaft of the machine by a driving band or chain. In this arrangement pro-
vision must be made for enabling the adjustable pedestal to vary slightly its
distance from the driven shaft so as to compensate for the shortening of the
driving band or chain produced by twisting the same when adjusting the
angle of the adjustable driving shaft. This adjustable apparatus also may be
'fixed to a convenient part of the combined thrashing machine for transmitting
motive power to the combined shaking and elevating machinery.

Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SHAKING,
RIDDLING, RAISING, AND DELIVERING STRAW, HAY, CORN, AND OTHER LIKE AGRI-
CULTURAL PRODUCE, AND IN THE MODE OF DRIVING OR TRANSMITTING MOTION
THERETO, PARTS OF WHICH IMPROVEMENTS ARE APPLICABLE TO THE DRIVING OR
TRANSMITTING OF MOTION TO OTHER MACHINERY," upon the condition (amongst

page_text: others) that we, the said James Hayes, the elder, Josiah Hayes, and Jame
Hayes, the younger, our executors or administrators, by an instrument i
writing under our 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, the said James Hayes, the elder, Josiah
Hayes, and James Hayes, the younger, 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,
reference being had to the accompanying Drawings, and to the letters and
figures marked thereon, that is to say :-
Our said Invention relates to a peculiar construction, arrangement, and
combination of machinery or apparatus for shaking, riddling, raising, and
delivering straw, hay, corn, and other like agricultural produce, and to a mode
or modes of driving or actuating the same, which apparatus may either be
mounted upon running wheels of its own and form an independent combined
straw shaker and elevator, or may be combined with a combined thrashing
machine, either fixed or portable, so as to form the combined straw shaking
and elevating mechanism of such machine.
In carrying out our Invention we propose to combine a set of straw
shakers, either of the ordinary construction or of the peculiar construction
herein-after described, with endless chains or bands or webs carrying con-
necting bars provided with teeth, tines, or projections travelling along a
trough or frame capable of being adjusted to any desired height or vertical
angle by the aid of rack and pinion gear or otherwise, whereby the straw will
be simultaneously shaken and elevated or delivered on to the stack. When
constituting an independent machine the various elements above referred to
will be all mounted upon and carried by a frame or carriage of its own pro-
vided with running wheels for the facility of transport, but when such elements
are to be combined with or form part of what is known as a "combined
thrashing machine" then the separate carriage and running wheels may be
dispensed with, as the framing of the thrashing machine itself will form the
carriage or support for the combined shaking and elevating mechanism, which,
when portable, will travel with the combined thrashing machine. When
constructed as an independent machine the combined straw shaker, elevator,
and riddle will consist of an inclined trough centred or pivoted at its lower
end upon the first-motion shaft of the machine. This shaft is carried in

page_text: bearings on the main framing, which is provided with running wheels for the
facility of transport. The trough is capable of adjustment to the desired
height or vertical angle by having racks attached thereto, into which gear
spur pinions actuated by a worm or endless screw supported on the fore part
of the 'main framing. The lower end of the trough contains a set of straw
shakers, which may be of the ordinary kind, but we prefer to adopt the
peculiar construction herein-after described. Our improved shakers are
made to vibrate in a vertical direction only and have no forward throw whatever,
as the travelling motion of the teeth, tines, or projections carried by the
connecting bars of the endless chains serves to move the straw along the
surface of the shakers. Each shaker vibrates vertically upon a fixed hinge
pin at its higher extremity, and in order to allow of the shakers rising and
falling in a parallel manner we insert a hinge joint therein a short distance
from the upper fixed end of the shaker, the portion comprised between the
two hinges acting as a link. The vibrating motion of the shakers is obtained
by connecting the under side of each shaker by means of links with two
vibrating arms or quadrants carried by two rocking shafts supported in
bearings attached to the trough. These shafts derive their rocking motion
from a crank on a second-motion shaft which is drawn by a pinion from the
driving shaft. The rocking motion of one shaft is transmitted to the other by
means of a coupling rod which connects two lever arms keyed on to the two
shafts respectively. The endless chains, bands, or webs which carry the
connecting bars containing the teeth, tines, or projections are supported on
flat-sided pulleys carried on the driving shaft at the lower end of the trough
and on a carrier shaft running freely on bearings at the top end of the trough,
and as the teeth, tines, or projections travel up the trough they carry along
with them the straw which is placed or made to fall in the lower end of such
trough, causing it to move along the surface of the shakers and to be finally
raised to the top of the stack or other elevated position. The teeth, tines, or
projections are guided so as to ensure their travelling along the intervening.
spaces between the shakers, whereby the latter will have free play vertically
without interfering or coming in contact with the tines or projections.. As in
some cases it may be found desirable that the travelling motion of the straw
whilst it is passing over the shakers should be slower than is requisite when it
is being simply elevated along the trough, we therefore propose sometimes to
use a second set of endless chains, bands, or webs, provided with teeth, tines,
or projections, each one of such second set of endless chains, bands, or webs
travelling along a slotted guide bar in the intervening space between each
pair of shakers, and extending only the length of the shakers, and be driveu

page_text: •
at a slower speed than the endless chains, bands, or webs which carry the straw
to the top of the trough. The second set of endless chains, bands, or webs
above referred to may be situate either above or below the shakers. When
the shaking and elevating machine is combined with a combined thrashing
machine, then the second set of endless chains, bands, or webs above referred
to should be situate underneath the shakers, the teeth, tines, or projections
which travel along the slotted guide bars between the shakers being made in
that case sufficiently long to project above the surface of such shakers so as
to carry the straw along the shakers to their upper ends, whence the straw
may be elevated in the usual manner. The corn and chaff as they leave the
shaker boxes fall on to a horizontal flat screen which vibrates in a circular
horizontal direction upon a vertical fixed pin or pivot, such vibrating motion
being imparted to the screen by a link and lever arm worked by one of the
rocking shafts above referred to. The screened corn is discharged from the
side of the screen by an inclined spout for that purpose attached to the under
side of the screen, and as it falls from this spout a blast of air from a fan
-blower is driven through it so as to carry off any chaff or light particles.
When forming part of a combined thrashing machine, this combined apparatus
will enable the straw to be shaken and elevated direct on to the stack as fast
as it leaves the beaters. When so employed the particular screen above
described may be dispensed with, and the corn and chaff may pass off from
the shaking boxes and be riddled and separated in the ordinary manner.
In
order to enable the machine herein-before described, whether used as an
independent machine or combined with a combined thrashing machine, of
which the improved combined shaking and elevating mechanism may form
a part, to be driven at any desired angle with the shaft transmitting
motion thereto, we propose to employ certain peculiar arrangements herein-
after described of adjustable driving gear, which arrangements are equally
applicable to the driving or actuating of other machinery under similar
circumstances.
According to one arrangement of driving gear we combine a spur pinion
carried on a shaft on which is fitted a driving pulley, such shaft working in a
pedestal which is adjustable to any desired angle, with a peculiar toothed
wheel which is keyed on the first-motion shaft of the combined straw shaker
and elevator, or such adjustable apparatus may be fixed to the combined
thrashing machine or other machine to be driven therefrom or in conjunction
therewith. This wheel in lieu of having the usual spur teeth formed thereon
has teeth of a circular, oval, or rounded contour when viewed on the face of
the tooth or in a direction at right angles to the axis of the wheel, and these

page_text: teeth are caused. to. overhang or project beyond the face or faces of the wheel
itself, so as to present a toothed surface not only at the external and internal
periphery of the wheel, but at. any 'intermediate angle. By making the
pedestal. bearing of the pinion adjustable in a circular direction the pinion
may be caused to gear with the teeth of the wheel in any position through
many. degrees of a circle, thereby combining, in one arrangement the pro-
perties of face gearing, external and internal spur gearing, and bevel gearing,
the motion in all positions being transmitted in a direct manner through the
gearing. When used.as internal spur gearing the actuating pinion should be
changed for one of smaller: pitch. In some cases, if desired, the peculiar
toothed wheel may be the driving wheel, and the pinion the driven wheel,
and the bearings of the shaft carrying the peculiar toothed wheel may be
made adjustable in the same manner as the bearing of the pinion in the first
instance, which mode of driving, if preferred, may be attached to a.convenient
part of the combined thrashing machine for the purpose of transmitting
motion to any other machinery intended to be driven in connection therewith;
or in lieu of a spur pinion carried on the adjustable driving shaft a bevel or
mitre wheel may be keyed thereon and made to gear into a bevel wheel fast
on a second shaft which carries another bevel wheel in gear with a bevel
wheel on the first-motion shaft of the machine to be actuated. This appa-
ratus, when required, may also be fixed to a convenient. part of the combined
thrashing.machine for the purpose above described. By making the plummer
block of the shaft which carries the first bevel wheel or pinion adjustable to
any position concentrically round the second shaft it will be obvious that the
driving pulley may be placed at any angle with the machine, and thereby
enable it to be driven at any angle with the shaft transmitting motion thereto;
or in lieu. of using toothed gearing a grooved or plane band pulley may be
fitted to the shaft, the pedestal of which is made adjustable to any angle, and
the motion from such pulley may be transmitted to a corresponding pulley on
the first-motion shaft of the machine by a driving band or chain. In this
arrangement provision must be made for enabling the adjustable .pedestal to
vary slightly its distance from the driven shaft so as to compensate for the
shortening of the driving band or chain produced by twisting the same when
adjusting the angle of the adjustable driving shaft. This adjustable apparatus
also may be fixed to a convenient part of the combined thrashing machine for
transmitting motive power to the combined shaking and elevating machinery,
or other machinery in conjunction therewith.
. And in order that the said Invention may be fully understood we shall now.
proceed more particularly to describe the same, and for that purpose shall

page_text: refer to the several Figures on the annexed Sheets of Drawings, the same
letters of reference indicating corresponding parts in all the Figures.
Figure 1, on Sheet 1 of our Drawings, represents a side elevation of our
combined machine for shaking, riddling, raising, and delivering straw, hay,
corn, and other like agricultural produce; Figure 2 is a corresponding plan of
the same; Figure 8 on Sheet 2 is a side elevation of the lower part of the
machine shewing the opposite side to that illustrated in Figure 1, and showing
also a different mode of driving the same; Figure 4 is a longitudinal section
of the lower part of the machine taken through the centre line of one of the
shakers; and Figure 5 is a transverse section taken through the set of
shakers. The rest of the Figures are details, which we shall herein-after more
particularly refer to.
In our Drawings we have represented the combined shaking, riddling,
raising, and delivering apparatus as constituting an independent machine com-
plete in itself, the main framing A of the machine being in that case mounted
upon running wheels B, B; C is an inclined trough which is centred at its
lower end on the first-motion shaft D of the machine carried in bearings E, E,
on the main framing A. Any convenient arrangement may be employed for
adjusting the trough C to the desired height or vertical angle; we prefer to
use for that purpose racks F actuated by spur pinions worked by a worm and
worm wheel, as shown in our Drawings. G, G, are the improved straw
shakers, which are caused to vibrate in a vertical direction only upon fixed
hinge pins H, H, at the higher extremities of such shakers; and in order
that the shakers may vibrate or rise and fall parallel to each other a
second hinge joint I, I, is introduced therein a short distance from the
upper fixed end, the portion or short length comprised between the two
hinges acting as a link. In practice these shakers will be in the form of
boxes, as heretofore constructed, but in order to avoid unnecessary compli-
cation in the Drawings we have only shewn the upper perforated surfaces
of such shaker boxes. These shakers derive their vibrating motion from
links K, K, jointed to the under side of the shakers and connecting them
with vibrating arms or quadrants L, L', mounted on two parallel horizontal
rocking shafts M, M³, carried in bearings attached to the trough C. N is a
second-motion crank shaft which imparts the rocking motion to the rocking
shaft M', through the intervention of the connecting rod O and lever arm P.
The motion of the shaft M' is transmitted to the corresponding shaft M by
the connecting or coupling rod Q and lever arms R, R'. S, S, are two
endless chains carrying connecting or cross bars T provided with teeth, tines,
or projections a, a, and supported on flat-sided pulleys U, U, fast on the

page_text: driving shaft D, and on similar pulleys V, V, mounted on a carrier shaft W
working in bearings b, b, at the upper end of the trough. ✗, X, are anti-
friction or supporting rollers for supporting the weight of the endless chains.
As the teeth a, a, on the under cross bars travel up the trough they carry
along with them the straw which is supplied to the lower end of the trough
and deliver the same from the upper end of the trough on to the top of the
stack, or other elevated position. These teeth traverse the intervening space
between the shakers G, thus, allowing free play to the latter, the teeth in
nowise, interfering with their vibrations. In order to ensure the accurate
traversing of the teeth between the shakers, and to prevent their coming in
contact therewith, we propose to guide the tines or projections by means of a
slotted or n-shaped guide bar X', as shewn in Figues 1 and 24, Sheet 1 of
our Drawings.. When using a second set of endless, chains, bands, or, webs
situate beneath the shakers we supply the intervening spaces between the
shakers with slotted guide bars for the same purpose. Y is a horizontal flat
screen or riddle which receives, a horizontal circular reciprocating motion from
a connecting rod Z and lever arm c, the latter being fast on the rocking shaft M.
d is a central vertical pin or pivot, upon which the screen or riddle vibrates.
The corn and chaff as they leave the shaker boxes fall on this screen, and the
chaff is discharged therefrom by falling over the edge of the screen, whilst the
screened corn falls into an inclined spout e, and is thereby delivered into
sacks or other receptacles, a blast of air from the blower & being directed
through the falling grain to drive off any remaining chaff or light particles.
We shall now proceed to describe our peculiar arrangements of adjustable
driving gear for enabling the machine herein-before described, whether¸ used
separately or combined with a combined thrashing machine, or for enabling
other moveable or fixed machinery to be driven at any desired angle with the
shaft, transmitting motion thereto.
According to one arrangement, which we have illustrated as being
applied to the machine herein-before described, we employ a spur pinion f
(Figures 1, and 2), carried on a short shaft 9, having a driving pulley, h
mounted thereon and working in an adjustable pedestal i, supported, on
the, fixed bed plate k attached to the main framing A of the machine;
this pedestal i is adjustable to any desired angle, either in a vertical or
horizontal direction in the example shewn in our Drawings; the adjust-
ment is in a horizontal plane, so as to cause the pinion f to describe a portion
of a circle in front of the edge of the peculiar toothed wheel k¹, which is
keyed on to the first-motion shaft of the machine to be driven., Figures 6
and 7 represent respectively an enlarged side elevation and transverse section

page_text: of a segment of this peculiar toothed wheel. 1, 1, are the teeth, which present
a circular, oval, or rounded contour when viewed on the face of the tooth or in
a direction at right angles to the axis of the wheel, as shewn in Figure 7;
such teeth being caused to project laterally beyond the side, face or faces of the
wheel, so as to present a toothed surface on the sides, as well as on the
periphery of the said wheel. By turning or adjusting in a circular direction
the pedestal i by the aid of a curved slot and tightening bolt, as shewn, the
shaft g may be made to assume any angle with the shaft or machine, trans-
mitting motion thereto without interfering with the gearing together of the
pinion and peculiar toothed wheel k¹.
According to another arangement of adjustable driving gear for the same
purpose, which we have shewn at Figure 3 (Sheet 2), applied to the machine
herein-before described, but which is equally applicable to other machinery,
we substitute for the spur pinion f on the driving shaft g and the peculiar
toothed wheel already referred to, a bevel or mitre wheel keyed on the
driving shaft g¹, which gears into a corresponding wheel m fast on the shaft n;
such shaft carrying a second bevel or mitre wheel o gearing into a corre-
sponding wheel p keyed on the first-motion shaft D of the machine. As the
pedestal or plummer block of the shaft g¹ is made adjustable in a similar
manner to that of the shaft g, herein-before referred to, so as to describe a
portion of a circle concentric with the shaft n, it follows that the shaft g' may
be adjusted to any desired angle without interfering with the gearing
together of the bevel wheels and m. Figure 8 represents the application of
the adjustable plummer block or pedestal to band and pulley driving gear.
In this case the shaft g working in the adjustable pedestal i carrying a pulley g,
which gives motion by a band or chain r to another pulleys keyed on the first-
motion shaft D of the machine. As the adjustment of the angle of the shaft g
will produce more or less twist or crossing of the band or chain r, and as this
will tend to vary the distance between the pullies 9 and s, provision must bo
made for adjusting the plummer block or pedestal i towards or from the shaft
D, according to the greater or less twist imparted to the band, belt, or chain r.
This may be accomplished in various ways, which will readily suggest them-
selves to the practical engineer, and therefore we have not considered it
necessary to illustrate the same in our Drawings.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried
into effect, we would observe in conclusion that what we consider to be novel
and original, and therefore claim as the Invention secured to us by the herein-
before in part recited Letters Patent is,-

page_text: 1st, the general construction, arrangement, and combination of machinery
or apparatus for shaking, riddling, raising, and delivering straw, bay, corn,
and other like agricultural produce, whether such machinery or apparatus
constitute a separate and independent machine or be combined with a
combined thrashing machine, so as to form part of the same, substantially
as herein-before described.
Second, the combination of straw shakers with straw elevators, capable
of adjustment to any desired angle or elevation, substantially as herein-before
described.
Third, the application and use of a second set of straw elevators travelling
either over or under the straw shakers at a slower rate than the elevators
which elevate and deliver the straw after it has passed over the shakers, sub-
stantially as herein-before described.
Fourth, the peculiar construction of toothed wheel or gearing herein-before
described and illustrated by Figures 6 and 7 of our Drawings.
Fifth, the application and use to and in the driving or actuating of straw
elevating and other machines of an adjustable pedestal or plummer block
in combination with a spur pinion, and the peculiar toothed wheel k³, or with
bevel or mitre wheels, or with pulleys and a driving strap, band, or chain, sub-
stantially as and for the purpose herein-before described and illustrated by
Figures 1, 2, 8, and 8 of our Drawings.
In witness whereof, I, the said James Hayes, the younger, on behalf of
myself and the said James Hayes, the elder, and Josiah Hayes, have
to this our Specification hereunto set my hand and seal, this Thir-
teenth day of October, One thousand eight hundred and sixty-six.
