hook is as wide as will pass through
the length of the link and narrow
enough at the middle of the bend to
allow the link to turn and bag the
other way. So long as the chains are
kept tight they cannot become unlock
ed. The hooks should also be turned
or faced in such way tnu1 they will
not be likely to catch the passing
plants or rubbish.
Clovis Is Adjustable.
The clevis o p is simply hinged. So
that there will be no tendency to pull
the front of the machine off of the
ground. and it is also broad enough In
front to allow of the point of draft be-
ing moved from one side to the other,
so that the front of the machine may
be thrown, closer to one row if desired
The front guard ON each side, b
c d, Is made of one piece of spring
steel seven eighths by three-sixteenths
OF an inch. This size seems sufficient
s1y strong and best adapted to carry
the tension of the chains d while
still yielding to the pressure against
the bases of the plants as they may
strike the outer sloping ends near d,
The inner ends of these guards a b
are horizontal. about eighteen inches
each in length. and serve to carry the
front guard above the draft bar II III

{ is about twelve inahes inn@. so that
the remainder Of the front guard from
{ 10 aeaf Il Viii be about four inches
above tie graaad. This prevents the
pushing OF dirt and squares toward
the pants and allows the chains TO
catch them where they lie. The hooks
ut d and are therefore bent down
i ward and somewhat backward through
about five or six inches. Care must be
taken. especially in forming the outer
ends between G and q. to secure best
results. The downward bend for the
hook at should not be abrupt, as
gradual slope helps to prevent catch
ing on any obstacles. The hooks at
and G are formed so as to hold the
chains firmly and yet not interfere
with the passage of rubbish,
The method of carrying the rear
ends of the outer chains is shown at
1 b 6. The piece k is nearly parallel
with the chains and may be used for
their proper adjustment as to tension
by several holes near the end where il
is bolted at k. The chains are be.
tween thirty and thirty six inches long.
The stand s. upon which the handles
are pivoted by one-half inch bolt, ia
made of piece of boiler plate bent
and cut so as to have a horizontal top
surface about four inches square and
standing about two and one.half
Inches above the draft bar, to which II
Is securely bottled.

Although the chain cnltivator was
designed primarily for bringing the

IN field practice TO have a most i'm

In order that the use of this machine
could be obtained by iii farmers at
the smallest possible cost patent
has been taken ont in the name of the
department Of agriculture and for tho
benefit of the people of the Unitei
States. Under this patent 1t is i'm.
possible for any pne to manufacture
the machine exclusively and to charge
unnecessarily high prices.
