Year: 1870

page_text: LETTERS PATENT to William Tasker, the younger, of the Waterloo
Iron Works, near Andover, in the County of Hants, for the Inven-
tion of "IMPROVEMENTS IN MACHINERY FOR ELEVATING CORN, HAY, STRAW,
AND OTHER AGRICULTURAL PRODUCE."
Scaled the 9th August 1870, and dated the 14th February 1870.
PROVISIONAL SPECIFICATION left by the said William Tasker, at tlio
Office of the Commissioners of Patents, with his Petition, on the
14th February 1870.
I, WILLIAM TASKER, the younger, of the Waterloo Iron Works, near
Andover, in the County of Hants, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINERY FOR ELEVAting Corn, Hay,.
STRAW, AND OTHER AGRICULTURAL PRODUCE," to be as follows:-
This Invention consists of a peculiar mode of raising the trough of an
elevator for corn, hay, straw, and other agricultural produce to any.
required position or height when at work, and also for shutting or
folding up the upper part of the trough of such elevator when not in use
or travelling, and for opening the same when required..

page_text: In carrying out my Invention I employ two or more poles on cach
side of the clevator by preference of metal, which poles are self-adjusting
or otherwise arranged and are of different lengths moving on or around
the same or different centres fixed to the sides of the carriage of the
machine. Two of the longer poles one on each side when raised may
be checked or are held in required positions at times by self-adjusting
chains or ropes.
On the top of each of these two poles is a pulley, over
which another chain or rope passes worked by a windlass for elevating
the trough and also for opening and shutting up the upper part of the
same. Two other poles shorter than the first-named working on or
around the same or different centres, cach fitted with a flanged wheel at.
-the opposite-end,-extend-forward_by_prefercuce_to_the_under_side_of_the_
top part of the trough of the clevator. To the outside of these wheels or
ends of the poles I attach the windlass rope or chain before referred to.
In shutting up part of the trough these two shorter poles pass on the
inside of the first-mentioned poles carrying the end of the trough with
them, describing part of a circle, and by the same chain or rope the
trough is lowered into the required position for travelling, the longer
poles tipping over slightly as the end of the trough passes the vertical
centre. To open the trough these operations have simply to be reversed.
The trough by preference is jointed in the middle..
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Tasker in the Great Seal Patent Office on
the 13th August 1870.
:
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM 2
TASKER, the younger, of the Waterloo Iron Works, near Andover, in the
County of Hants, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of February, in the
year of our Lord One thousand eight hundred and seventy, in the thirty- 3
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Tasker, the younger, Her special
license that I, the said William Tasker, the younger, my executors,
administrators, and assigns, or such others as I, the said William Tasker,
the younger, my executors, administrators, or assigns, should at any time a

page_text: 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 "IM-
PROVEMENTS IN MACHINERY FOR ELEVATING CORN, HAY, STRAW, AND OTHER
AGRICULTURAL PRODUCE," upon the condition (amongst others) that I, the
said William Tasker, the younger, my executors or administrators, 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 William Tasker, the younger, 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, reference being had to the Drawings
hereunto annexed and to the letters and figures marked thereon (that
is to say)
My said Invention consists of a peculiar mode of raising the trough of
an elevator for corn, hay, straw, and other agricultural produce to any
required position or height when at work, and also for shutting or.
folding up the upper part of the trough of such elevator when not in use.
for travelling and for opening the same when required.
In carrying out my Invention I employ two or more poles on each
side of the elevator (by preference of metal), which poles are self-
adjusting or otherwise arranged and are of different lengths moving on
or around the same or different centres fixed to the side of the carriage
of the machine. Two of the longer poles, one on each side, when raised
may be checked or are held in required position, and at times by self-
adjusting chains or ropes or by truss bars or props. On the top of cach
of these two poles is a pulley, over which another chain or rope passes
worked by a windlas for clevating the trough and also for opening and
shutting up the upper part of the same. Two other poles shorter than
the first-named working on or around the same or different centres, each
fitted with a flanged wheel at the opposite end extend forward by
preference to the under side of the top part of the trough of the elevator.
To the outside of these wheels or ends of the poles I attach the windlas
rope or chain before referred to. In shutting up part of the trough,

page_text: same; C is one of the two poles. On a friction wheel D carried by cach
pole the trough rests, such trough being raised or lowered by means of
two side ropes or chains E which pass over pullies F at the tops of the
two upright poles G. The poles G are kept in the required position by
two truss bars H (one of which only is seen in the Drawing), which
work at their opposite ends in long slots I at the top of the frame A.
By means of these truss bars the two side poles G can be fixed in any
required position to suit the inequalities of the ground on which the
elevator may be standing. K is the windlass or drum, on which the side
ropes E are coiled by means of the handle L and a worm and worm
wheel. The drum K is placed by preference on a spindle made of iron
pipe through which is passed a bolt, and by tightening the nut M. the
drum is firmly connected with the pole G by means of a conical friction
ring and groove a shewn in dotted lines, when by winding the drum the
poles G can be raised or lowered. When the poles G are in the position
required by unscrewing the nut M the windlass is at liberty to move
independently of the poles. By turning the handle L the poles C which
support the end of the trough are elevated, and by so doing the trough
is raised to any position required. The friction wheel D on the poles C
allows the said poles to traverse the under side of the trough. By
removing a pin N in the joint of the trough.and repeating the operation.
as for raising the trough is folded and the poles G can be lowered in the
same manner as they were raised.
The above is the way I prefer to carry out my Invention, but it is
obvious that slight modifications or alterations can be made without
departing from the main features thereof.

page_text: Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the com-
bination of the moveable poles C and G and ropes or chains E with a
hinged or jointed trough and windlass, substantially as and for the
purpose herein-before described.
In witness whereof, I, the said William Tasker, the younger, have
to this my Specification set my hand and seal, the Twelfth day
of August One thousand eight hundred and seventy.
