IMPROVEMENTS IN DRILLS FOR DRILLING CORN, GRAIN, AND MANURE
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HALL NALDER, of Alvescott, in the County of Oxford, Gentleman, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-eighth day of June, in the ninth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
James Hall Nalder, Her especial licence, full power, sole privilege and
authority, that I, the said James Hall Nalder, my exors, admors, and assigns,
or such others as I, the said James Hall Nalder, my exors, adiñors, or
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN DRILLS FOR DRILLING
CORN, GRAIN, AND MANURE;" in which said Letters Patent is contained a proviso
that I, the said James Hall Nalder, shall cause a particular description of
the nature of my said Invention, and in what manner the same is to be
performed, to be inrolled in Her said Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said in
part recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Hall Nalder, do hereby declare that the nature of my said Invention

page_text: Man and to the figures and rewers marked
thereon, that is to say:―
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 shew the two side views of a drill constructed according to
my Invention; and Figure 3 is a plan thereof, suitably arranged for drilling
corn or grain. Figure 4 shews a transverse section, and Figure 5 a back
view of so much of the drill as is to be used when drilling turnip seed or other
grain with manure, the apparatus in these Figures being substituted for the
upper parts of the drill shewn at Figure 1 as is shewn at Figure 2 before
mentioned. The other Figures of the Drawings shew various details of the
apparatus, in order that their construction may be better understood than
they could be in the other Figures. It should be stated that in all the Figures
of the Drawings the same letters are used to indicate similar parts. a, a, are
the wheels which carry the drill. These wheels are capable of moving back
freely on their axle b, but when the wheels a, a, move forward they become
fast to the axle by reason of ratchet wheels and clicks or catches, as shown in
the Drawings, and as heretofore practised in drills. On the axis 6 is fixed
the toothed wheel c, which takes into and drives the toothed wheel d on the
axis e, such axis being connected by an universal joint or coupling f to the
axis e', and the axes e, e', turn in bearings e, e, fixed to the frame of the
machine and in the bearing at e', carried by the lever g, so that the toothed
wheel d may be lifted out of gear with its wheel c by the lever g, such lever
when raised being supported in the support g' at the upper part of the guide
plates g, between which the lever is raised and lowered. On the axis e¹ are
two bevilled toothed wheels h, i, which are capable of sliding on the axis e',
but are caused to turn with that axis. j is a lever for sliding the bevelled
wheels on the axis e', so as to bring either h or i into gear with the bevelled
toothed wheel k on the axis l, or the lever j is capable of retaining both the
wheels h, i, out of gear with the wheel k, the lever j being held in either of
the three positions by the stud (passing through the slot in the lever)
entering one or other of the three holes formed in the fixed plate j. The
axis has affixed on it a bevelled toothed wheel m, which takes into and
drives the bevelled toothed wheel n on the axis n', and on this axis n¹ is a
toothed wheel o, which gives motion to the apparatus for feeding the corn or
grain to the drills.
And I would remark, that the first part of my Invention consists in the

page_text: pecular arrangement or the axis, and means or obtaining motion thereto
and transmitting motion therefrom to the axis n', as herein described The
toothed wheel o takes into and give smotion to the toothed wheel p on
the axis p', on which is affixed the apparatus q, shewn by dotted lines in
Figure 1, for measuring the quantity of corn or grain, as heretofore practised,
there being one sets of measuring cups for each drill, each wheel of cups
delivering into a tin funnel r, which delivers into other tin funnels r', r, into
the pipes of the drills, the nature of which, and of the drills themselves, will
readily be traced in the Drawing, and they do not form any part of my
Invention. In Figure 2, the apparatus, Figures 4 and 5, is shewn applied
in place of the apparatus just described. In this case only two drills are used,
the others being removed, and the box containing the seed and manure does
not move on necks or axes, as in Figure 1, but is fixed, there being no tilting
required, in consequence of other means being applied for regulating the
quantity of the delivery by the cups. And this apparatus consists of a sliding
plate. is a sliding plate, which can readily be raised or lowered by means
of the handle s affixed on the axis s, on which axis are two toothed
wheels, and they take into two racks s' affixed on the plate s so as to raise
or lower it; and the plate is held to any position by the notched wheel s
affixed on the axis s³, which is retained by the catch s. The toothed wheel o
takes into and gives motion to the wheel t, which is on the axis t¹ of the
apparatus for feeding or supplying manure to the drills. On the axis t¹ there
is another wheel t, which gives motion to the toothed wheel u on the axis u',
which is one of the axes which keep the manure stirred up, and v is the other
stirring axis which receives motion from the toothed wheel w on the axis u',
which takes into the toothed wheel on the axis v. The wheel t on the
axis t' gives motion to the wheel x on the axis a³, on which is affixed the
apparatus for feeding or supplying the seed to the drills, as is well understood;
but in place of having the cups y so as to measure only one quantity, I prefor
to make them capable of containing and contracting according to the size
desired to be used; and this improvement consists in making each cup of two
parts y, y', the part y' being capable of movement, so as to enlarge or decrease
the size of the cup, as is shewn. On the axis t, in addition to the ordinary
cups t, I apply a series of bent blades t, which serve to cut portions of
manure which are afterwards thrown forward by the cups t³. In this
machine only one funnel tube is used between the box containing the manure
and the drill, as is shewn, there being a funnel for delivering the seed from
the cups y into the lower funnel tube, as shewn. z is a hind wheel, applied
when desired to the drill, as shewn in Figure 2.

page_text: Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would wish it to be understood that I
do not confine myself to the precise details shewn, provided the peculiar
character of either part of my. Invention be retained; but what I claim is,―
First, the mode of obtaining motion to the axis l, and transmitting motion
therefrom.to.the.axis n', as herein described.
Secondly, I claim the sliding plates, acted on by racks and apparatus for
moving and retaining the same in position, as described.
Thirdly, I claim the mode of constructing the cups y, y', as herein
described. And,
Fourthly, I claim the application of the bent blades & in combination with
cups, as herein described.
In witness whereof, I, the said James Hall Nalder, have hereunto set my
hand and seal, this Twenty-fourth day of December, in the year of
our Lord One thousand eight hundred and forty-five
JAMES HALL (L.8.) NALDER.
AND BE IT REMEMBERED, that on the Twenty-fourth day of December,
in the year of our Lord 1845, the aforesaid James Hall Nalder came before
our said Lady the Queen in Her Chancery, and acknowledged the Specifica-
tion aforesaid, and all and every thing therein contained and specified, in
form above written. And also the Specification aforesaid was stamped
according to the tenor of the Statute made for that purpose.
Enrolled the Twenty-seventh day of December, in the year of our Lord'
One thousand eight hundred and forty-five.
