The Distance between the Plank and the cross Piece is Eleven Inches.
The Breadth of the cross Piece is Two Inches and a quarter. This cross
Piece is shewn apart in _Fig._ 2. where its Two Standards A B, are each
Seventeen Inches long (or high), and each on its fore Side and hinder
Side One Inch and a quarter broad, and nearly Three quarters of an Inch
thick: They are shoulder’d and pinn’d into the cross Piece at _a b_.
The cross Piece is Thirteen Inches and an half long, and one Inch and a
quarter thick in the Middle from _c_ to _d_; but for about an Inch on
the Inside of each Standard is Two Inches and an half thick, that the
Standards may have the more Wood to support them, and that the Hopper,
bearing upon the thicker Parts of the cross Piece, may be held up above
the Funnel, that the Fork of the brass Spindle may not strike against
it, when the Plough is taken up to be turn’d, there being a little more
than a quarter of an Inch of the Breadth of the cross Piece behind the
Standard, for the Hopper to rest on.
The whole Distance between the Standards is Nine Inches and a quarter.
The Standards must be exactly perpendicular to their cross Piece: Their
Tops are drawn up each to a Point, as at _e_ and _f_, by which the
Hopper is the more easily put on upon them.
The Funnel, Sheat, Share, and Trunk, are the same as those in the
Wheat-drill, except a few Differences: As G in _Fig._ 1. is the same as
the fore Sheat of the Wheat-drill, with its Accoutrements; only it is
lower, being but Eight Inches high from the Bottom of the Share up to
the Beam; and the Plates of the Trunk are somewhat narrower: Its Tenon
passes thro’ the Beam, and comes up above it, betwixt the Funnel and
the cross Piece; and there is pinn’d in thro’ its Hole above the Beam.
There is no want of Wood behind the Sheat, the Funnel not being cut in
the Beam, but placed upon it.
The Funnel is shewn apart in _Fig._ 3. and is Two Inches deep, Four
Inches square at Top; its Four Sides terminating at an Hole in the
Bottom, half an Inch broad from _a_ to _b_, and near an Inch long from
_c_ to _d_, which Length is divided in the Middle, by the upper Edge of
a Brass Spout, which divides the Hole into Two equal Parts (or Holes),
each of which is about half an Inch square; this Funnel being screw’d
on upon the Beam by Two Wood Screws, entering at Two opposite Corners
of the Funnel, as at _c d_ in _Fig._ 1. so that the Seed may drop from
the Seed-box upon the right Side of the Funnel at _e_, which being
about half an Inch distant from the Partition, and equidistant from
both Holes, the Seed rebounding is pretty equally distributed to each
of the Holes.
