IMPROVEMENTS IN DRILLS FOR AGRICULTURAL PURPOSES
Year: 1853

page_text: LETTERS PATENT to William Tasker, of the firm of Tasker and
Fowle, of the Waterloo Iron Works, near Andover, in the County
of Hants, for the Invention of "IMPROVEMENTS IN DRILLS FOR
AGRICULTURAL PURPOSES."
Sealed the 28th December 1853, and dated the 30th June 1853.
PROVISIONAL SPECIFICATION left by the said William Tasker
at the Office of the Commissioners of Patents, with his Petition,
on the 30th June 1858.
WILLIAM TASKER, of the firm of Tasker & Fowle, of the Wa-
terloo Iron Works, near Andover, in the County of Hants, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN DRILLS
FOR AGRICULTURAL PURPOSES " to be as follows:-
This Invention consists in placing a cylinder or portion of a cylinder
in the bottom of a box containing manure to be drilled; round this fixed
cylinder a fluted cylinder revolves, the flutes or projections of which
being in close contact with the exterior of the fixed cylinder form a
number of cavities into which the manure falls, and by the revolution
of the cylinder is conveyed through conducting pipes into the ground.

page_text: The revolving cylinder may be fixed either on a square or round spindle
traversing the whole length of the box, and any number of such cylin-.
ders may be fixed thereon. A rotary motion is given by different
sizo
cog wheels fixed at the end of spindle in connection with that fitted
on the travelling wheel of the machine, which acts as a driving wheel.
By this Invention it is obvious that the friction produced by
cylinder revolving round the other prevents the machine from clogging,
and adapts it for drilling artificial manures in their original state and
in any desired quantities. >
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said William Tasker in the Great Seal Patent Office,
on the 80th December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1.
WILLIAM TASKER, of the firm of Tasker and Fowle, of the Waterloo
Iron Works, near Andover, in the County of Hunts, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of June, 'in the year of
our Lord One thousand eight hundred and fifty-three, in the seventeenth
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto mic, tho said William Tasker, Her special license
that I, the said William Tasker, my executors, administrators, and
assigns, or such others as I, the said William Tasker, 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 Iuvention. for "IMPROVEMENTS IN
DRILLS FOR AGRICULTURAL PURPOSES," upon the condition (amongst others)
that I, the said William Tasker, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the naturo
of the said Invention, and in what manner the same was to be per-
formed, 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 Patont.
NOW KNOW YE, that I, the said William Tasker, do hereby
declare the nature of my said Invention, and in what manner the saine
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:
My said Invention relates to a peculiar arrangement of mechanism
for giving a regular and constant supply of manure from the manure
box in manure distributors, and consists in placing a cylinder or portion
of a cylinder in the bottom of a box containing manure to be drilled;
round this fixed cylinder a fluted cylinder revolves, the flutes or pro-
jections of which being in close contact with the exterior of the fixed
cylinder form a number of cavities into which the manure falls, and
by the revolution of the cylinder is conveyed through conducting pipes
into the ground. The revolving cylinder may be fixed either on a
square or round spindle, traversing the whole length of the box, and
any number of such cylinders may be fixed thereon. A rotatory motion
is given by different sized cog wheels fixed at the end of a spindle in
connection with that fitted on the travelling wheel of the machine,
which acts as a driving wheel. By this Invention it is obvious that
the friction produced by one cylinder revolving round the other
prevents the machine from clogging, and adapts it for drilling artificial
manure in their original state and in any desired quantities. Figure 1,.
on the accompanying Sheet of Drawings represents a complete side
elevation of the drill, shewing the gearing for driving the fluted
rollers and other working parts of the machine; Figure 2, is a
longitudinal vertical section of the drill; and Figures 3, and 4,
represent in detail a side elevation and end view of the distributing
cylinders drawn half the real size. A, is the manure box, divided
into as many compartments as there are coulters in the machine, and
fitted with revolving agitators B. The fluted cylinders C, are fitted
beneath each compartment on to the transverse shaft D, which-carries
a spur wheel E, at one end outside the body of the drill. This wheel
is driven by the spur wheel F, which receives its motion from a spur

page_text: wheel G, fixed to the inside of the navo of one of the running or
carrying wheels. The wheel G. gears with the spur wheel H, which
transmits its movement to the loose wheel I. This wheel is fitted
with two side projecting lugs, which are acted upon by the arms of the
wheel E. and are consequently carried with it. The apparatus is
thrown out of gear by the lever K, which pushes back the wheel I.
and withdraws it from contact with the spur wheel H. The spur
wheel E, gears with the carrier wheel L, which works loosely upon an
adjustable stud centre. This wheel gives motion to the small spur
wheel M, on the end of the seed-distributing shaft N, which is fitted
with cup wheels in the ordinary manner. The distributing cylinder is
composed of two parts, one fixed and the other moveable. The move-
able or rotatory part O, is cast with a central boss P, which is fitted on
to a square portion of the shaft. 1). It consists of a series of transverse
bars Q, which slide over the fixed segmental plates R, bolted to the
side of the conductor S, by the flanges T. As fast as the manure in
the box A, comes in contact with the revolving portion of the cylinders,
it is conveyed into the conductor S, whence it falls into the cans U, and
is deposited into the ground in the ordinary manner. The size of the
openings through which the manure passes to the cylinders is regulated
by the sliding door V, which is actuated by the screw W, and pinion X,
which gears s with a rack on the body of the door or sliding plato V.
By this means the door is raised or lowered, and the apertures for the
passage of the manure are consequently increased or diminished. By the
employment of the peculiarly formed cylinders herein-before described
all chances of clogging or filling up is entirely obviated, since the
constant traversing or rubbing of the cylinder over the fixed segmental
plates before mentioned keeps the cylinder always clean.
Having now described and particularly ascertained the nature of iny
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe, in conclusion, that I do not
confine or restrict myself to the precise details or arrangements which T
have had occasion to describe or refer to, as many variations may be
made therefrom without deviating from the principles or main features
of my said, Invention; but what I consider to be novel and original,

page_text: and therefore claim as the Invention secured to me by the herein-before
in part recited Letters Patent, is,-
First, the general arrangement and construction of manure dis-
tributors, as herein-before described.
Second, the application and use of a cylinder having openings in its
surface, revolving externally over fixed segmental plates, in the manner
and for the purpose herein before described.
In witness whereof, I, the said William Tasker, have hereunto
hand and seal, the Twenty-eighth day of December,
set
my
One thousand eight hundred and fifty-three.
WILLIAM TASKER. (L.S.)
