ROBERT HALL, of Foxholes, in the County of York, Agricultural Implement
Maker. "IMPROVEMENTS IN STEAM CULTIVATING, AND IN ENGINES, IMPLEMENTS,
AND APPLIANCES CONNECTED THEREWITH."
The first part of Invention consists in the construction and arrangement of
engines used for agricultural purposes, with a double set of drums, all as here-
after described. By this means I am enabled to use the power of both engines at
one and the same time on one implement, and by a modification, as hereafter
described, I am able to use the power of the two engines for working two or two
sets of implements; by these means I am able to employ engines of less power than
heretofore, and thereby I materially reduce the expense of steam cultivating
machinery.
The drum proper carries an internal cog wheel, into which a pinion gears, to
which motion is communicated from the engine. A sheave pulley or ring runs on
the upper flange of the druin, and acts as an anchor for the rope from the opposite
engine. Each engine is preferably at each end provided with pulleys and drums, as
before described, and I preferably place the drums with their spindles in a vertical
direction. I connect one end of one rope to the implement which is to be drawn,
and pass the same rope round the sheave ring on the drum of that engine which
the implement is approaching; the same rope is then carried back over suitablo
porters to the drum of the other engine, is fastened thereto, and coiled round the
same. A second rope from the implement passes to and round the aforesaid drum of
the first-named engine, to which drum it is fastened, and round which it coils; thus
both engines are both drawing the implement in one direction at one and the same
TD 0.11

page_text: time, and in this way I obtain from the constant work of, say two six-horse engines,
the power usually obtained from the intermittent or alternate working of two
twelve-horse engines. When the implement arrives at "lands end "both engines
are stopped, the drums thereon, which have been at work, are thrown out of gear,
and the others are put into gear, whereby the implement is turned and drawn to
the opposite headland, and so on. The hinder part of implement is provided with
shaft, having pulleys on same, which carry or support the outer drawing and paying
out ropes; and in this way I am able to dispense with the use of some of the rope
porters usually employed.
Where I use the same engines for working two implements or sets of implements,
I prefer to reverse the positions of the engines from that which they occupied in the
previous arrangement, so that the drums may give off their ropes at their outer cir-
cumferences instead of at their inner, as in the arrangement previously described, for
drawing only one implement at a time, and this is done in order to allow as much
room as possible for the implements to pass one another.
Supposing I wish to use a harrow with a drill to follow, I connect the harrow to
rope, which is carried to and coiled round the forward drum of the engine, at, say,
the right-hand headland; then when the harrow is pulled up to this engine the
forward drum on engine at left-hand headland is thrown into gear and the harrow
is drawn back; the drill is connected to rope, which is carried to and coiled round
the hinder drum of the engine at left-hand headland; then when the drill is pulled
up to this engine the hinder drum on engine at the right-hand headland is thrown
into gear and the drill is drawn back, and so on. By this arrangement the two im-
plements are moving in opposite directions, both engines being continually utilized
for drawing the one or the other implement, and in this way I am enabled to have
two different classes of implements working disconnectedly on the same land at one
and the same time.
