IMPROVED MACHINERY FOR REMOVING OR ELEVATING STRAW AND OTHER AGRICULTURAL PRODUCE
Year: 1859

page_text: In the Matter of a Patent granted to SAMUEL WILLIAM CAMPAIN, of
Deeping Saint Nicholas, in the County of Lincoln, Farmer, for his
Invention of "IMPROVED MACHINERY FOR REMOVING OR ELEVATING
STRAW AND OTHER AGRICULTURAL PRODUCE," bearing date the 10th
day of December 1859, (No. 2810.)
DISCLAIMER AND MEMORANDUM OF ALTERATION proposed to be
entered by the said Samuel William Campain to the Specification of
the said Patent pursuant to an Act passed in the 5th and 6th years of
His late Majesty's reign, intituled "An Act to amend the Law touching
Letters Patent for Inventions."
WHEREAS since the filing of the Specification of my said Patent I have
discovered that certain parts of the apparatus therein described are of no
practical utility, and therefore are never used by me, and that I have also
been advised that certain other parts of the apparatus referred to in my said
Specification are not described with sufficient minuteness and detail to enable
others to make and use the same. And whereas some of the parts above
referred to do not constitute part of my Invention, but are merely accessaries
thereto, and which may or may not be used therewith, I am desirous of
amending my said Specification by striking out therefrom all such parts as are
defective and of no utility, I therefore, for the above-mentioned reasons, do
hereby disclaim and strike out from my said Specification the following parts,
(viz.), from lines 8 to 13 of page 5 of the Queen's Printers' copy of my said

page_text: Specification, commencing with the words "by attaching books," and ending
with the words "the ground;" from the word "for," at the end of line 17,
page 6, to the words "chain or band," at line 24 in the same page; also the
words "and also the mode of constructing these and the other vertical sup-
ports of the said rope, chain, or band," as printed at lines 4 and 5, page 8, all
of which parts are struck through in red ink in the Queen's Printers' copy of
my said Specification left herewith.
And I do hereby declare that after the parts herein referred to have been
struck out, my said Specification as amended will read as follows:-
My Invention of "Improved Machinery for Removing or Elevating Straw
and other Agricultural Produce" relates to a means whereby trusses of straw
or sheaves of corn may be removed from one place to another and elevated by
mechanical means when required to form a stack, instead of it being necessary
for the workman to carry the truss or sheaf up a ladder by hand.
The improved apparatus consists principally of a travelling rope, chain, or
band, adapted to a driving roller and passed round a suitable pulley or pullies
arranged in such a manner that they may be adapted to an upright post,
whereby the said pullies, and consequently the elevated end of the carrying
rope, may be raised to the desired height. To this travelling rope, chain, or
band, are adapted hooks, catches, or other analogous contrivances, whereby
the trusses or sheaves may be suspended from the said rope, chain, or band.
In carrying out my Invention and adapting it to assist in forming a stack
of corn or straw the travelling rope, chain, or band, which is of considerable
length, is passed round a distance pulley which is adapted to a vertical post
or pole that is firmly secured at some spot beyond the place where it is
intended to form the stack, which must be made at some spot between this
vertical post or pole and the stationary winding apparatus whereby the travel-
ling rope, chain, or band is actuated. It will now be understood that if a
truss or sheaf be hooked on or temporarily attached to the travelling rope,
chain, or band, and the latter be set in motion by actuating the winding
apparatus, the said truss or sheaf will be carried along over the spot where
the stack is to be or is being formed, when it will be detached by the attendant
and deposited in its proper place on the stack. The distance pulley over
which the travelling rope, chain, or band passes, is attached to a ring that is
capable of being moved up or down the vertical post or pole by means of a
cord or chain passed over a pulley or sheave at the top of the pole. It will
therefore be understood that as the stack increases in height the distance
pulley of the travelling band is elevated or raised up the pole so that the
trusses or sheaves may be carried up to the required height. It will some-

page_text: times be found convenient to place an intermediate support for the travelling
band, rope, or chain, between the winding apparatus and the vertical distance
pole. It will of course be understood that two or more hooks, catches, or
other analogous contrivances may be attached to the travelling rope, chain, or
band, so that while one truss or sheaf is travelling forward to the stack, other
hooks or catches are returning from the stack towards the winding apparatus
for the purpose of receiving other trusses or sheaves. I sometimes find it
convenient to construct the hooks or catches in such a manner that the trusses
may be detached therefrom by simply pulling a cord and withdrawing a pin
or other analogous contrivance from the hook or catch, thereby loosening the
band which holds the straw and allowing the trusses to fall down. By means
of this arrangement the attendant below may not only attach the trusses to the
travelling rope, chain, or band, and thereby raise them to any required height,
but he may also detach them from the travelling rope, chain, or band, without
other aid, leaving the man on the stack free to arrange the trusses in their
proper order and places on the stack.
In the accompanying Drawing I have shewn various views of my improved
machinery or apparatus. Fig. 1 is a side elevation of the apparatus complete.
Fig. 2 is a front elevation of the winding drum and apparatus for actuating
the same.
a, a, is the winding drum round which is wound the rope, chain,
or band b, b. Both ends of this rope are secured to the winding drum, and it
is passed round the distance pulley c, which is, by means of suitable tackle d,
attached to or connected with the upper end of the moveable half of the
vertical pole c.
It will be seen that the pole e is divided into two parts, e
and e*, the former of which is moveable vertically like the topmast of a ship,
and may be raised up from time to time by means of the tackle f. An obvious
modification of this plan of raising the pulley c, and with it the end of the
travelling rope b, is to secure the pulley c to a moveable ring or pulley which
may be moved up a fixed pole instead of raising part of the pole itself, as
shewn in the Drawing. When forming stacks of large size it will be found
desirable to make use of an intermediate support for the travelling rope,
chain, or band b, as shewn at e¹, e, Fig. 1. It will be found convenient to
construct this intermediate support in two parts, as shown, one being fixed
and the other moveable. The upper end of the moveable part e¹ of the pole
carries a cross arm e³ provided at each end with a pulley over which the
travelling rope, chain, or band 6 passes. The straw or other substance is
collected in trusses, sheaves, or bundles, of convenient size, and is secured by
a band or strap 9 which is attached permanently at one end to an arm or
lever h, as seen best in the enlarged detached views, Fig. 3, 4, and 5, and is

page_text: secured temporarily to the other end of the arm or levér h by means of a hook
or catch i. The arm or lever h is suspended from a hook or link j which is
secured to the travelling rope, chain, or band, as at h. The tail i* of the
catch or hook i extends upwards and rests between the forked end of the
lever 1, which turns on a pin fixed in the hook or link j.
It will now be understood, on inspecting the Drawings, that the bundle of
straw having been secured in the strap or band g, and motion having been
communicated to the travelling rope, chain, or band b, the bundle of straw will
be carried up over the stack and the projecting end of the lever I will be
brought against a fixed arm m near the distance pulley c, and the lever / will
be consequently forced back and will draw out the catch i, release the end of
the strap g, and allow the bundle of straw to fall on to the stack. An obvious
modification of this contrivance is to dispense with the lever and to attach a
string or cord to the tail end of the book or catch i, so that the attendant
below may release the straw when it has reached the proper place above the
stack, or the man on the stack may himself release it, leaving to the man
below nothing to do but to secure the bundles by means of the strap 9, and
then raise them by communicating motion to the winding drum either by
hand or by means of suitable driving gear, as shewn in the Drawing.
This driving gear consists of a flanged pulley n mounted on a vertical shaft
which is provided with a clutch o and two bevil pinions p, p* which turn freely
on the shaft, except when they are in gear with the clutch o. Both of these
pinions gear into the bevil wheel q on the axle of the winding drum a, and it
will therefore be evident that by throwing one or other of these driving pinions
into gear with the clutch o the winding drum may be driven in either direc-
tion, as may be required. On the opposite end of the axle of the winding
drum is a snail or worm r which gears into and drives a pinion s at one end
of the oblique or diagonal shaft t, shewn by dots in Fig. 1. The opposite end
of the shaft t carries a small pinion u which gears into and drives a rack on
the bar v. Forked arms v¹, v², are secured in any convenient manner on the
bar for the purpose of guiding the rope or chain b as it is wound on to or
passes off the winding drum. The clutch o is thrown in or out of gear with
the pinions p, p*, when required by means of the weighted hand lever w. The
snail or worm r on the end of the winding drum gears into and drives a
horizontal worm wheel a on the upper end of the vertical shaft a³, and a
toothed pinion a² on the lower end of this shaft gears into a toothed rack on
the end of the rod y and communicates a lateral motion thereto. A block y'
fixed on the rod y works to and fro between two studs 21, 23, keyed on to the
horizontal rod z, and when the block y' comes against either of these studs

page_text: or 2, it drives it forward, and by throwing the clutch out of, gear with either
of the pinions the motion of the winding drum will be stopped until the clutch
be again thrown into gear with one or other of the pinions by means of the
hand lever w. The outer end of the rod z is jointed to one end of the bell-
crank lever w³, while the opposite end of this lever is jointed or connected to
the vertical rod w2, whereby the clutch o is worked.
It will be obvious to any intelligent mechanic that although the drum n
may also be driven in the same direction, the winding drum may be made to
rotate first in one and then in the other direction, as may be required. It
will be obvious that the winding drum may, if preferred, be arranged to be
rotated by means of a winch handle on the end of the axle, or by means of a
pair of bevil wheels, one on the end of the drum axle and one on an inde-
pendent axle, to be worked by hand. In order to enable the travelling part
of the rope, chain, or band b to be extended or lengthened I divide the
winding drum into two parts, constituting two separate drums on one shaft;
one of the drums is keyed permanently on to the shaft, and the other drum is
connected to the fixed drum by means of a clutch, when, therefore, the clutch
is ungeared one half of the drum may be made to unwind the rope while the
other remains stationary.
Having now described my Invention of "Improved Machinery for Removing
or Elevating Straw and other Agricultural Produce," and having explained
the manner of carrying the same into effect, I claim as the Invention secured
to me by Letters Patent as aforesaid, the mode herein set forth of carrying,
removing, or elevating straw or other agricultural produce, and of depositing
the same on the stack.
I claim particularly connecting the distance pulley c, round which the
travelling rope, chain, or band is passed, to a vertical post in such a manner
that the pulley, and with it the end of the travelling rope, chain, or band is
capable of being raised from time to time as the stack increases in height.
I claim, also, connecting the trusses, sheaves, or bundles of straw or other
agricultural produce to the travelling rope, chain, or band, by means of straps
or bands secured by hooks, catches, or other analogous contrivances, as herein
set forth.
I further claim the use of intermediate supports for the travelling rope,
chain, or band.
In witness whereof, I, the said Samuel William Campain, have hereunto
set my hand and seal, this Fourteenth day of July, in the year of our
Lord One thousand eight hundred and sixty-four.

page_text: LETTERS PATENT to Samuel William Campain of Deeping Saint
Nicholas, in the County of Lincoln, Farmer, for the Invention of
REMOVING OR ELEVATING STRAW AND
"IMPROVED MACHINERY FOR
AGRICULTURAL PRODUCE."
Sealed the 27th April 1860, and dated the 10th December 1859.
PROVISIONAL SPECIFICATION left by the said Samuel William Campain
at the Office of the Commissioners of Patents, with his Petition, on the
10th December 1859.
I, SAMUEL WILLIAM CAMPAIN, of Deeping Saint Nicholas, in the County
of Lincoln, Farmer, do hereby declare the nature of the said Invention
for "IMPROVED MACHINERY FOR REMOVING OR ELEVATING STRAW AND
AGRICULTURAL PRODUCE," to be as follows:-
My Invention of improved machinery for removing or elevating straw and
other agricultural produce relates to a means whereby trusses of straw or
sheaves of corn may be removed from one place to another, and elevated by
mechanical means when required to form a stack, instead of it being necessary
for the workman to carry the truss or sheaf up a ladder by hand.

page_text: The improved apparatus consists principally of a travelling rope, chain, or
band adapted to a driving roller, and passed round a suitable pulley or pullies
arranged in such a manner that they may be adapted to an upright post,
whereby they may be elevated to the desired height. To this travelling rope,
chain, or band are adapted hooks, catches, or other analogous contrivances,
whereby the trusses or sheaves may be suspended from the said rope, chain,
or band.
In carrying out my Invention and adapting it to assist in forming a stack
of corn or straw, the travelling rope, chain, or band, which is of considerable
length, is passed round a distance pulley, which is adapted to a vertical post or
pole that is firmly secured at some spot beyond the place where it is intended to
form the stack, which must be made at some spot between this vertical post or
pole and the stationary winding apparatus, whereby the travelling rope, chain, or
band is actuated. It will now be understood that if a truss or sheaf is hooked
on or temporarily attached to the travelling rope, chain, or band, and the latter
be set in motion by actuating the winding apparatus, the said truss or sheaf
will be carried along over the spot where the stack is to be or is being formed,
when it will be detached by the attendant, and deposited in its proper place on
the stack. The distance pulley over which the travelling chain passes is
attached to a ring that is capable of being moved up or down the vertical post
or pole by means of a cord or chain passed over a pulley or sheave at the top
of the pole. It will therefore be understood that as the stack increases in
height the distance pulley of the travelling band is elevated or raised up the
pole, so that the trusses or sheaves may be carried up to the required height.
It will sometimes be found convenient to place an intermediate support for the
travelling band, rope, or chain between the winding apparatus and the vertical
distance pole. It will, of course, be understood that two or more hooks,
catches, or other analogous contrivances may be attached to the travelling
rope, chain, or band, so that while one truss or sheaf is travelling forward to
the stack, other hooks or catches are returning from the stack towards the
winding apparatus for the purpose of receiving other trusses or sheaves. I
sometimes find it convenient to construct the hooks or catches in such a
manner that the trusses may be detached therefrom by simply pulling a cord
and withdrawing a pin or other analogous contrivance from the hook or catch.
By means of this arrangement the attendant below may not only attach the
trusses to the travelling rope, chain, or band, and thereby raise them to any
required height, but he may also detach them from the travelling rope, chain,
or band without other aid, leaving the man on the stack free to arrange the

page_text: trusses in their proper order and places on the stack. By attaching hooks or
suitable apparatus to the travelling rope, chain, or band, and arranging the
latter in a suitable manner for the purpose, the latter may, if required, be
made to collect the straw in bundles, sheaves, or trusses automatically, thereby
saving the time of a laborer. This will be found convenient when the straw. is
being discharged from a thrashing machine on to the ground..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel William Campain in the Great Seal Patent Office
on the 9th June 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
WILLIAM CAMPAIN, of Deeping Saint Nicholas, in the County of Lincoln,
Farmer, send greeting.
WHEREAS Her most Excellen Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of December, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Samuel William Campaia, Her special license that I, the said
Samuel William Campain, my executors, administrators, and assigns, or such
others as I, the said Samuel William Campain, 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 "IMPROVED MACHINERY FOR REMOVING OR ELEVATING STRAW AND OTHER
AGRICULTURAL PRODUCE," upon the condition (amongst others) that I, the said
Samuel William Campain, by an instrument in writing under my hand and
seal, 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 I, the said Samuel William Campain, do hereby
declare the nature of the 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):-

page_text: My Invention of "Improved Machinery for Removing or Elevating Straw
and other Agricultural Produce," relates to a means whereby trusses of straw
or sheaves of corn may be removed from one place to another, and elevated by

proper place on the stack. The distance pulley over which the travelling rope,
chain, or band passes, is attached to a ring that is capable of being moved up or
down the vertical post or pole by means of a cord or chain passed over a pulley
or sheave at the top of the pole. It will therefore be understood that as the
stack increases in height the distance pulley of the travelling band is elevated
or raised up the pole, so that the trusses or sheaves may be carried up to the
required height. It will sometimes be found convenient to place an inter-
mediate support for the travelling band, rope, or chain between the winding
apparatus and the vertical distance pole. It will, of course, be understood
that two or more hooks, catches, or other analogous contrivances may be
attached to the travelling rope, chain, or band, so that while one truss or sheaf
is travelling forward to the stack, other hooks or catches are returning from
the stack towards the winding apparatus for the purpose of receiving other
trusses or sheaves. I sometimes find it convenient to construct the hooks or

and thereby raise them to any required height, but he may also detach them
from the travelling rope, chain, or band without other aid, leaving the man on
the stack free to arrange the trusses in their proper order and places on the stack.
By attaching hooks or suitable apparatus to the travelling rope, chain, or
band, arranging the latter in a suitable manner for the purpose, the latter may,
if required, be made to collect the straw in bundles, sheaves, or trusses
automatically, thereby saving the time of a labourer. This will be found con-
venient when the straw is being discharged from a thrashing machine on to
the ground.
In the accompanying Drawing I have shewn various views of my improved
machinery or apparatus. Fig. 1 is a side elevation of the apparatus complete;
Fig. 2 is a front elevation of the winding drum and apparatus for actuating
the same.
a, a, is the winding drum, round which is wound the rope, chain,
or band b, b. Both ends of this rope are secured to the winding drum, and it
is passed round the distance pulley c, which is by means of suitable tackle d
attached to or connected with the upper end of the moveable half of the
vertical pole c. It will be seen that the pole is divided into two parts e
and e*, the former of which is moveable vertically like the topmast of a ship,
and may be raised up from time to time by means of the tackle f. An
obvious modification of this plan of raising the pulley c, and with it the end of
the travelling rope b, is to secure the pulley c to a moveable ring or pulley,
which may be moved up a fixed pole instead of raising part of the pole itself,
as shewn in the Drawing. When forming stacks of large size, it will be
found desirable to make use of an intermediate support for the travelling rope,
chain, or band b, as shewn at e¹, e, Fig. 1. It will be found convenient to
construct this intermediate support in two parts, as shown, one being fixed and
the other moveable. The upper end of the moveable part e' of the pole
carries a cross arm e³ provided at each end with a pulley, over which the
travelling rope, chain, or band 6 passes. The straw or other substance is
collected in trusses, sheaves, or bundles of convenient size, and is secured by a
band or strap g, which is attached permanently at one end to an arm or
lever h, as seen best in the enlarged detached views,. Figures 3, 4, and 5, and
is secured temporarily to the other end of the arm or lever h by means of a
hook or catch i. The arm or lever h is suspended from a book or link j

page_text: which is secured to the travelling rope, chain, or band, as at k. The tail * of
the catch or hook i extends upwards, and rests between the forked end of
the lever 1, which turns on a pin fixed in the hook or link j.
⚫ It will now be understood, on inspecting the Drawings, that the bundle of
straw having been secured in the strap or band g, and motion having been
communicated to the travelling rope, chain, or band b, the bundle of straw
will be carried up over the stack, and the projecting end of the lever / will be
brought against a fixed arm m near the distance pulley c, and the lever / will
be consequently forced back, and will draw out the catch i, release the end of
the strap g, and allow the bundle of straw to fall on to the stack. An obvious
modification of this contrivance is to dispense with the lever 1, and to attach a
string or cord to the tail end of the hook or catch i, so that the attendant
below may release the straw when it has reached the proper place above the
stack, or the man on the stack may himself release it, leaving to the man
below nothing to do but to secure the bundles by means of the strap 9, and
then raise them by communicating motion to the winding drum, either by
hand or by means of suitable driving gear, as shewn in the Drawing. For
the convenience and facility of forming the straw into bundles, trusses, or
sheaves, the straw as it comes out of the thrashing machine is scraped by
reciprocating or vibrating tines or prongs into a long box, which will contain
a sufficient quantity to form one or two bundles. One side or end of this box
is hinged, so that by opening the same the straw will fall out of the box on to
the strap or band, and may then be secured ready to be hooked on to the
travelling rope, chain, or band.
This driving gear consists of a flanged pulley n mounted on a vertical
shaft, which is provided with a clutch and two bevil pinions p, p, which
turn freely on the shaft, except when they are in gear with the clutch o.
Both of these pinions gear into the bevil wheel 9 on the axle of the winding
drum a, and it will therefore be evident that, by throwing one or other of these
driving pinions into gear with the clutch o, the winding drum may be driven
in either direction, as may be required. On the opposite end of the axle of
the winding drum is a snail or worm r, which gears into and drives a pinion s
at one end of the oblique or diagonal shaft t, shewn by dots in Fig. 1. The
opposite end of the shaft carries a small pinion u, which gears into and
drives a rack on the bar v. Forked arms v1, v2, are secured in any convenient
manner on the bar v for the purpose of guiding the rope or chain 6 as it is
wound on to or passes off the winding drum. The clutch o is thrown in or out
gear with the pinions p, p, when required, by means of the weighted hand
of

page_text: lever w..
The snail or worm r, on the end of the winding drum, gears into
and drives a horizontal worm wheel a on the upper end of the vertical shaft a',
and a toothed pinion on the lower end of this shaft gears into a toothed
rack on the end of the rod y, and communicates a lateral motion thereto. A
block y, fixed on the rod y, works to and fro between two studs 1, 2, keyed
on to the horizontal rod z, and when the block y' comes against either of these
studs or 3, it drives it forward, and by throwing the clutch out of gear with
either of the pinions, the motion of the winding drum will be stopped until
the clutch be again thrown into gear with one or other of the pinions by
means of the hand lever w. The outer end of the rod z is jointed to one end
of the bell-crank lever w¹, while the opposite end of this lever is jointed or
connected to the vertical rod w2, whereby the clutch o is worked.
It will be obvious to any intelligent mechanic, that although the drum n
may also be driven in the same direction, the winding drum may be made to
rotate first in one and then in the other direction, as may be required. It will
be obvious that the winding drum may, if preferred, be arranged to be
rotated by means of a winch handle on the end of the axle, or by means of a
pair of bevil wheels, one on the end of the drum axle and one on an inde-
pendent axle to be worked by hand. In order to enable the travelling part of
the rope, chain, or band 6 to be extended or lengthened, I divide the winding
drum into two parts constituting two separate drums on one shaft; one of the
drums is keyed permanently on to the shaft, and the other drum is connected
to the fixed drum by means of a clutch; when, therefore, the clutch is ungeared,
one half of the drum may be made to unwind the rope while the other remains
stationary.
Having now described my Invention of "Improved Machinery for Removing
or Elevating Straw and other Agricultural Produce, and having explained
the manner of carrying the same into effect, I claim, as the Invention secured
to me by Letters Patent as aforesaid, the mode herein set forth of carrying,
removing, or elevating straw or other agricultural produce, and of depositing
the same on the stack.
I claim particularly connecting the distance pulley c, round which the
travelling rope, chain, or band is passed, to a vertical post in such a manner
that the pulley, and with it the end of the travelling rope, chain, or band,
is capable of being raised from time to time as the stack increases in
height.
I claim, also, connecting the trusses, sheaves, or bundles of straw, or other
agricultural produce to the travelling rope, chain, or band by means of straps

page_text: or bands secured by hooks, catches, or other analogous contrivances, as herein
set forth.
I further claim the use of intermediate supports for the travelling rope,
chain, or band, and also the mode of constructing these and the other vertical
supports of the said rope, chain, or band.
In witness whereof, I, the said Samuel William Campain, have hereunto
set my hand and seal, this Seventh day of June, in the year of our
Lord One thousand eight hundred and sixty.
