REAPING MACHINES.

Illustration: (‡ DRAY) REAPING MACHINE.

Illustration: SICKLE.

Machines have lately been produced to effect more rapidly, what has

hitherto been done by hand, with the sickle, namely, the reaping of

corn. These machines are of various kinds, but the one that seems

most perfect has been patented by Messrs. Dray & Co.; it consists of

a heavy wooden frame drawn by a horse, and having wheels attached,

which on turning round set in motion a line of spear-headed knives;

these knives are made sharp at each side, to cut both ways. The

motion communicated to them is very rapid, and from side to side, so

as to cause the knives to pass through long narrow openings made to

fit them in a series of iron points which are placed one between each

knife. This action causes the point and knife to act like the blades

of a pair of scissors, only that the points are fixed and the blades

move through them, cutting off the corn at any distance from the

ground that may be required; at the side furthest from the horse is

a point of iron, having two diverging pieces prolonged from it, and

which pierces the corn and separates the portion to be cut from what

is to be cut at the next return of the machine; for it is drawn up

and down, cutting at each time a belt about four or five feet wide;

when cut, the corn falls on a platform balanced on its centre, and

capable of being turned so as to incline forwards or backwards. A

man sits on the machine with a rake, and as the platform fills with

cut corn, he pushes it with the rake, tilting the platform back and

delivering the corn behind, where women attend to bind it up. These

machines can reap ten or eleven acres in a day.
