PLUCKNETT's HAND AND HORSE DRILL MACHINES, AND THE METHOD OF FIXING HIs UNDER-FURRO Ww DRILL TO A PLOUGH,

[Pith a Plate annéted.]

In the last Number of our Magazine, we gave 2 description of a e Patent hand single-row Dibbling Machine,?? invented by Mr. Plucknett, and we have now the pleasure of introducing to the reader, two Drilling Machines, constructed by the same ingenious mechanic,

A, Fig. 1, are two handles, by which a man wheels it A along these are fastened to à box B, containing the seed to be sown. D D, the wheels; these are fixed fast to an axle which goes through the box, and has a small-toothed wheel, E, fixed to it, s0 as to turn round with the wheels. F js 4 crooked iron, similar to the anchor of a clock’ escapement,

G, jointed to the end of it, by which means it communicates ils motion to the short lever k, on whose Spindle the two feeding rolls(similar to those described at page 290 of our last) are fixed. i

The coulters, Fig. 2, are nailed to the front of the box, and have a hollow behind, in which the edge of the feedin wheel works, s0 as to throw the seed into the drill cut by the fore edge of the coulter.

Mr. Plucknett also makes an únder-furrow drill machine, nearly similar to the above, to be affixed to a plough.

Tt is smaller, has.no handles, but one wheel, and a single feeding roll, it is connected with the plough, by an iron, Fig 3, the end e of which is nailed to the side of the box B, the other end is screwed to the beam. This iron has two Joints in it, by which it can swiyel in any direction, and adapt itself to the inequalities of the ground. The machine is also steadied by two small chains, hooked to staples at each cor-
