IMPROVEMENTS IN THE CONSTRUCTION OF ELEVATORS FOR STACKING HAY, CORN, AND STRAW
Year: 1870

page_text: LETTERS PATENT to William Andrews, of Melksham, in the County
of Wilts, Agricultural Implement Manufacturer, for the Invention
of "IMPROVEMENTS IN THE CONSTRUCTION OF ELEVATORS FOR STACKING HAY,
CORN, AND STRAW."
Sealed the 23rd May 1871, and dated the 24th November 1870.
PROVISIONAL SPECIFICATION left by the said William Andrews at
the Office of the Commissioners of Patents, with his Petition, on the
24th November 1870.
I, WILLIAM ANDREWS, of Melksham, in the County of Wilts, Agri-
cultural Implement Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF ELEVATORS FOR
STACKING HAY, CORN, AND STRAW," to be as follows:-
This Invention relates to the construction of elevators by means of
which hay, corn, and straw can be stacked with great facility, whilst by
dispensing with the framework which is ordinarily employed for tho

page_text: support of the trough when lowered, the machinery can be packed in a
small compass when not in use. At the lower end of a trough similar
to that used in machines for like purposes, and which is well known and
understood, and on each side thereof, an iron bracket is bolted which
serves as an axle for the travelling wheels. A spindle on which are
keyed two chain pulleys passes through the brackets. A third wheel
with a hollow axle is connected with a moveable frame, which latter is
jointed to the trough near the centre thereof. A rope or chain is fixed
to the frame at the axis of the third wheel, and passes over a winding
barrel placed under the chain pulleys at the travelling wheels, the barrel
being caused to rotate and so strain the rope or chain and draw the third
wheel towards the travelling wheels, thus raising the trough by means of
the frame attached to the former by means of a winch, ratchet, and
lever, or any other of the well-known contrivances adapted for the
purpose. A projection is fixed on the moveable frame to support the
trough when lowered and ready for travelling. The third wheel works
on a swivel, so that it will turn as may be required, and when the
trough is in a position for work is fixed and kept in a line therewith by
means of a pin which is passed through the frame and the axle of the
wheel.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Andrews in the Great Seal Patent Office
on the 24th May 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ANDREWS, of Melksham, in the County of Wilts, Agricultural Imple-
ment Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of November, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me; the said William Andrews, Her special licenco
that I, the said William Andrews, my exccutors, administrators, and
assigns, or such others as I, the said William Andrews, my executors,
administrators, and assigns, should at any time agree with, and no

page_text: 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
THE CONSTRUCTION OF ELEVATORS FOR STACKING HAY, CORN, AND STRAW," upon
the condition (amongst others) that I, the said William Andrews, 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 Scal
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 Andrews, 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 annexed Drawings,
and to the figures and letters marked thereon, that is to say :-
My said Invention relates to the construction of elevators by means of
which hay, corn, and straw can be stacked with great facility, whilst by
dispensing with the framework which is ordinarily employed for the
support of the trough when lowered the machinery can be packed in a
small compass when not in use, the cost of manufacture being also con-
sequently reduced. At the lower end of a trough similar to that used in
machines for like purposes (and the nature of which is well known and
understood), and on each side thereof a cast or wrought-iron bracket is
bolted or otherwise fixed, and which serves as an axlo for the travelling
wheels. The axle is hollow and serves as a bearing for a spindle, on
which are keyed two chain pulleys. Two additional wheels are provided
the same being connected by a transverse bar, to which is attached a bar
or beam which is jointed to the trough near the centre thereof. The
last-mentioned wheels with their attachments may be termed the "frout
carriage." The axle of these wheels is below the transverse bar, and is
made a fixture to the bar or beam connected with the trough. A
winding barrel is placed over the last-mentioned wheels or in a con-
venient position with relation thereto, and over the barrel are passed
ropes or chains which are connected to the two cast or wrought iron
brackets. Upon the winding barrel being caused to rotate by any

page_text: suitable means the ropes or chains are wound round the same and the
front carriage is drawn towards the travelling wheels, thus by means of
the bar or beam jointed to the trough, clevating the latter to any desired
angle, at which it may be retained by a ratchet arrangement, screws,
stops, or any other of the well-known mechanical contrivances adapted
to the purpose.
Instead of employing two wheels for the front
carriage as herein-before mentioned, one swivel wheel may be used,
the same being so arranged that it will turn as may be required, and
when the trough is in a position for work is fixed and kept in a line
therewith by means of a pin which is passed through the frame and the
axle of the wheel.
I will now proceed to refer to the annexed Drawings from which the
nature of my said Invention will be more clearly understood.
.
Figure 1 is a side elevation of the apparatus, and Figure 2 is a trans-
verse section of a portion thereof. In these Figures the same letters
refer to similar parts.
A, A, are the travelling wheels; B, is the trough; C, the brackets;
D, the spindle, on which are keyed the chain pulleys E, E; F is the bar
or beam jointed to the trough, and by which the latter is raised to the
required angle; G is the rope or chain; H, the winding barrel; I, the
transverse bar forming the lower part of the front carriage, and under-
neath which the axle J locks round, the axle J being made a fixture to
the carriage when used for clevating the trough by means of suitable
stops. K in Figure 1 represents one of the wheels of the front carriage.
The position of the trough when it is elevated in the manner before
described is shewn in dotted lines.
Having thus declared and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I would observe in
conclusion that what I consider novel and original and therefore claim
as constituting the Invention secured to me by the said herein-before in
part recited Letters Patent are,-
Firstly. Driving the main spindle on which are keyed the two chain
pulleys through the hollow axles of the two travelling wheels, as herein-
before described.
Secondly. The mode of elevating the trough by drawing the front and
hind wheels nearer together, as herein-before described.

page_text: And, thirdly. The combination and arrangement of parts and mechanism
substantially as and for the purposes herein-beforo described and set forth,
or any mere modifications thereof.
In witness whercof, I, the said William Andrews, have hereunto set
my hand and seal, this 22nd day of May, in the year of our Lord
One thousand cight hundred and seventy-one.
