Year: 1861

page_text: LETTERS PATENT to Henry Brinsmead, of Ipswich, in the County of
Suffolk, Machinist, for the Invention of "IMPROVEMENTS IN APPARATUS
FOR RAISING AND STACKING STRAW AND OTHER AGRICULTURAL PRODUCE."
Sealed the 18th March 1862, and dated the 23rd September 1861.
PROVISIONAL SPECIFICATION left by the said Henry Brinsmead at the
Office of the Commissioners of Patents, with his Petition, on the 23rd
September 1861.
I, HENRY BRINSMEAD, of Ipswich, in the County of Suffolk, Machinist,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN APPA-
RATUS FOR RAISING AND STACKING STRAW AND OTHER AGRICULTURAL PRODUCE," to
be as follows:-
In all the sets of apparatus hitherto used for this purpose in connection with
that kind of machine well known as combined portable thrashing machines,
the same has been constructed upon an independant framing, and carried
about upon a separate carriage from that constituting the framing and carriage
of the combined portable thrashing machine.
Now, the object of this Invention is to use the framing and carriage of the
combined portable thrashing machine as the chief support and portable
carriage for the apparatus composing the straw elevator, and in the general
arrangement of this consist the improvements of the apparatus. It may be

page_text: well to avoid any misconception of what is intended in these improvements to
guard against the idea that this apparatus is intended to supersede or is
merely an addition to the straw shakers, which, in some cases, do in their
very action elevate the straw to some slight extent; but this is not their
object, neither have they hitherto been so constructed in these machines as to
make the slight elevation which they give to straw of any practicable use as
straw elevators.
The improved apparatus for the purpose of elevating the straw receives the
same after it has been submitted to the action of the shakers. It must be
clearly understood that I do not confine myself to the adoption of any one of
the present well-known modes or systems of apparatus as now used, or to any
special apparatus whatever, as it will be obvious that any one of them can be
so modified as to be adapted to the framing of the thrashing machine, and be
carried about upon the same set of road wheels.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Brinsmead in the Great Seal Patent Office on the
22nd March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BRINSMEAD, of Ipswich, in the County of Suffolk, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of September, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Brinsmead, Her special licence that I, the said Henry Brinsmead,
my executors, administrators, and assigns, or such others as I, the said
Henry Brinsmead, 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
APPARATUS FOR RAISING AND STACKING STRAW AND OTHER AGRICULTURAL PRODUCE,"
upon the condition (amongst others) that I, the said Henry Brinsmead, 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

page_text: Office within six calendar months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that I, the said Henry Brinsmead, 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 thereof, that is to say:-
In all the sets of apparatus hitherto used for this purpose in connection with
that kind of machine well known as combined portable thrashing machines, the
same has been constructed upon an independent framing, and carried about
upon a separate carriage from that constituting the framing and carriage of
the combined portable thrashing machine.
Now, the object of this Invention is to use the framing and carriage of the
combined portable thrashing machine as the chief support and portable
carriage for the apparatus composing the straw elevator, and in the general
arrangement of this consists the improvements of the apparatus. It may be
well to avoid any misconception of what is intended in these improvements to
guard against the idea that this apparatus is intended to supersede, or is
merely an addition to the straw shakers, which, in some cases, do in their
very action elevate the straw to some slight extent; but this is not their
object, neither have they hitherto been so constructed in these machines as to
make the slight elevation which they give to straw of any practicable use as
straw clevators.
The improved apparatus for the purpose of elevating the straw receives the
same after it has been submitted to the action of the shakers. It must be
clearly understood that I do not confine myself to the adoption of any one of the
present well-known modes or systems of apparatus as now used, or to any
special apparatus whatever, as it will be obvious that any one of them can be
so modified as to be adapted to the framing of the thrashing machine, and be
carried about upon the same set of road wheels.
Having described the nature of my Invention, I will now describe the
accompanying Drawings which illustrate two of the best methods of elevating
straw with which I am acquainted, and clearly illustrate the carrying out this
Invention; I do not, however, confine myself thereto.
Sheet I. illustrates the application of this Invention to an apparatus for
raising and stacking straw, for which Letters Patent bearing date the 10th
day of September, in the year of our Lord 1860, were granted to William
Wilkinson and Henry Thompson Wright.
Figure 1 is a side elevation, Figure 2 is a plan, of part of the apparatus.
which is permanently fixed to the framework of the combined portable

page_text: thrashing machine; Figure 3 is a front view. The same letters refer to the
same parts in the three views.
A is the front part of a combined portable thrashing machine, or that part
where the straw is delivered from the shaker. a is a moveable circular frame
of T-iron, supported by and baving a sliding motion in two brackets b, b,
fixed to the framework of the thrashing machine; c is a circular bar, also of
T-iron, permanently fixed to the framework of the thrashing machine con-
centric with the moveable frame a; d is a bar projecting from the back part
of the moveable frame a, to reach the fixed bar c, to which it may be clamped
by a screw at its extremity for the purpose of holding the moveable frame a
in any required position when working the straw elevator at an angle with
the thrashing machine; e, e, are two drums fixed to the moveable frame a,
over which pass the endless ropes or chains carrying the network. Motion
is communicated to either of the drums by the pinion f, which can be shifted
to either side for that purpose. The pinion f receives motion from one of the
spindles of the thrashing machine; in this a pulley 7 is fixed to the crank
spindle h, which actuates the riddles of the thrashing machine, but is capable
of being adjusted longitudinally along the spindle. The pulley g communicates
motion by a strap to the pulley i and its spindle j. The spindle k, which
carries the pinion f, is connected with the spindlej by a universal joint;
m, m, are two bearings in the moveable frame a, to receive the spindle / when
required to drive the opposite drum. The bearing for the spindle has a
sliding motion on the bar l, and can be clamped tight in any position, so that
when working the straw elevator at an angle with the thrashing machine the
spindle j may be set parallel with the crank spindle h; n, o, are tubes sliding
one inside the other, the tubes o being connected by a frame p, to which are
fixed the drums q, to receive the endless chains or ropes carrying the net-
work. The lower ends of the tubes n rest in sockets r, which play freely on
a tube s, which serves as an axle for the wheels or rollers t, and has a ratchet
and pawl u.
On the central part of the tube s is another tube v, also having
a ratchet and pawl w. Ropes a, with suitable blocks, serve to raise the
tubes o, and ropes y passing round a stake z driven firmly into the ground, and
wound upon the tube v, serve to give the tubes the necessary inclination for
delivering the straw at the elevation required. The Drawing shews the appa-
ratus fixed in a position ready for work.
When it is required to travel the ropes x and y are slackened until the
frame p reaches the ground. The endless ropes or chains, with the network, are
detached from the drums q, and are coiled on to a roller fixed in any convenient
position on the thrashing machine. The chain braces 1 and 2 are then

page_text: slackened and unhooked at one end and the strut bar 3 taken out. The
frame

with the drums q, can then be readily detached from the tubes o.
The tubes n can also be detached from 'the sockets », and placed on brackets
placed to receive them at the side of the thrashing machine. All the other
parts are packed in and about the thrashing machine, so as to travel with
safety and convenience.
Sheet II. illustrates the application of this Invention to an apparatus for
raising and stacking straw, &c., for which Letters Patent, bearing date the
3rd day of June, in the year of our Lord 1853, were granted to James Hayes.
Figure 1 is a side elevation; Figure 2 is a front view; Figure 3 is a plan.
The same letters refer to the same parts in all three views.
A is a frame, to which are clamped the tubes B; the tubes are braced by
the wire ropes C, the lower one of which carries the bottom D, made after
the manner of patent window shutters, so as to admit of being coiled on a
roller; E is a roller fixed to the frame A; F is a roller fixed to the ends of
the tubes B; G, G, are straps, armed with spikes, passing round the rollers
E, F, and are strained to the requisite tightness by the screws a at the ends
of the tubes B. The frame A is supported by a bracket b, which has motion
across the machine by the racks and pinions c, d, actuated by the worm wheel
and crank e. f. The tubes B are held at the requisite inclination by the
ropes H, which pass over the sheaves I at the top of the posts J, and thence
round the drums K. The drums K are furnished with ratchets, so as to
admit of being turned independent of the spindle L and of each other when
the straw elevator is required to be placed at an angle with the thrashing
machine. In raising and lowering the straw elevator both the drums K are
actuated simultaneously with the spindle L by means of the worm wheel and
crank g, h. The posts J rest on suitable brackets fixed, to the thrashing
machine, and are braced by chains M attached to the rear end of the machine,
and also by chains N, attached to the naves of the front wheels, and a chain O
connecting their upper ends. For communicating motion to the straw
elevator, each end of the spindle for the roller E is fitted to receive a bevel
wheel i, which is actuated by the pinion j. The spindle k carrying the
pinion has a universal joint, and is driven by the spindle 7, to which is
fixed the pulley m, which receives motion from a pulley n fixed to one of
the spindles of the thrashing machine.
When the straw elevator is to be packed for travelling or removal, the
bottom D is coiled round the roller E; the tubes B and ropes C are taken out
of the frame A, and fixed in brackets placed at the side of the machine for
their reception. The roller F, with the straps G coiled round it, are placed on

page_text: the frame A, which is wound up by the chain o close to the frame of the thrashing
machine. The posts J, with the chains M, N, O, are packed on the top of
the machine. The ropes H are coiled round the drums K.
Having described the nature of my Invention and some of the methods
of performing the same, I would have it understood that I do not confine
myself to either of the two systems of apparatus berein described, nor
to any special apparatus whatever; but what I claim is, the using of the
framing and carriage of the combined portable thrashing machine as the chief
support and portable carriage for the apparatus composing the straw elevator,
and the adaptation of the latter to the framing of the thrashing machine, so
that it may be carried about upon the same set of road wheels.
In witness whereof, I, the said Henry Brinsmead, have hereunto set
my hand and seal, this Twentieth day of March, in the year of our
Lord One thousand eight hundred and sixty-two.

of Ipswich, Accountant.
