allow the link to turn and bag the

kept tight they cannot become unlock

or faced in such a way that they will

How to Adjust Chains.
The vertical section between and
c is about twelve inches long. so that
the remainder of the front guard from
C to near d will be about four inches
above the ground. This prevents the
pushing of dirt and squares toward
the plants and allows the chains to
catch them where they lie. The hooks
at d and e are therefore bent DOWN
| ward and somewhat backward through
about five or six inches. Care must be
taken. especially in forming the outer
ends between and d. to secure l,est
results. The downward bend for the
hook at should not be abrupt. ns
gradual slope helps to prevent catch
ing on any obstacles. The hooks mt
t 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 Mt
/ h 6. The piece Is nearly parallel
with the chains and may be used for
their proper adjustment as to tension
by several holes near the end where II
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. Is
made of a 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 bolted.
Handles Adjust Chains.
The handles are bolted. as Mt +. to
the heavy pieces Of iron (ahout two by
one-half inch tire steeD. which are

Made Of Tire Steel.
Ordinary tire steel about one by one
fourth inch may be used for all parts
like the clevis p. rear arches h m
and 6 and braces k and j e.
The front guard b d should be
of spring steel. as specified. The rivef
heads on the front guard should be
round and fit smoothly. In nearly all
other places the irons are fastened to-
gether by one-fourth inch square head
ed bolts. with washers as needed.
Although the chain cultiyator was
designed primarily for bringing the
squares TO the mfddles, 1t was found
In field practice to have most I'M
portant cultural effect.
In order that the use Of this machine
could be obtained by all farmers at
the smallest possible cost a patent
has been taken ont In the name Of the
department of agriculture and for the
benefit Of the people Of the United
States. Under this patent It Is Inn
possible for any one to manufacture
the machine exclusively and to charge
