I CRISPUS COTTIS of Epping in the County of Essex Agricultural Implement
Maker, do hereby declare the nature of this invention to be as follows:-
This Invention relates to the delivery conductors of agricultural drills through
which the corn, seed, etc. is delivered from the hopper to the coulters; and it has for
its object to provide conductors which are flexible, extensible, and contractible, and
capable of adapting themselves to the various lateral adjustments and rising and
falling movements of the coulters in substitution for the sets of conical delivery tins
and chains usually employed.
The Invention consists of a conductor constructed of a spirally coiled strip of sheet
metal or wire forming a continuous conductor of conical form the coils or convolutions
of which fit within or are so formed relatively to, each other that the conductor may
be collapsed into a small compass, or extended to the required extent.
Dated this 26th day of October 1886.

page_text: An Improvement in Agricultural Drills.
I CRISPUS COTTIS of Epping in the County of Essex, Agricultural Implement
Maker, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to the delivery conductors of Agricultural drills through
which the corn, seed, etc. is conveyed from the hopper to the drills or channels made
in the ground by the coulters; and the invention consists in an improved construction
of flexible extensible and contractible conductors which are capable of adapting them-
selves to the various lateral adjustments and rising and falling movements of the
coulters. The improved delivery conductor is constructed of a strip of sheet metal or
wire coiled spirally into the form of a slightly conical tube capable of being collapsed
or extended longitudinally, as required. These improved conductors are to be used
in lieu of the sets of delivery funnels and chains, and when applied to old drills they
would be simply hooked on in the old way, but in applying them to new drills
advantage would be taken of the elasticity of the conductor which would then be so
secured at the upper and lower ends that it will act as a spring in compression and
tend to force the coulter into the ground, and render unnecessary the use of weighted
levers for the purpose.
Reference is to be had to the accompanying drawings forming part of this specifica-
tion wherein figure 1 represents the improved conductor as applied to any ordinary
form of drill, and figure 2 shows one of the conductors (drawn to a larger scale and
partly in section) provided with means of fixing its ends, so that it will act as a spring,
as above specified.
The conductor A is made of a taper strip of thin sheet steel of sufficient length and
width when coiled as herein described, to form a slightly conical tube of about
two feet in length. The thickness of the steel would depend upon the strength of
spring required (which would vary for heavy or light drills for heavy or light land)
but would generally correspond to from No. 20 to No. 26 B. W. G. After being
coiled and drawn out to the intended form and length it is tempered in the usual
manner of tempering springs. The coils or convolutions fit closely on each other as
shown, and the upper or larger end of the conductor is rivitted in a flanged ring B.
adapted to be secured in position to receive the seed etc. from the hopper whilst the
lower or smaller end is clamped in a split socket C attached to the coulter lever or
other secure fastening D. By using a conductor of sufficient length and compressing
it longitudinally, it will act as a spring to force the coulter into the ground. If the
conductor be made of wire, the latter may be of round, square or other section and

page_text: would be coiled spirally to a more conical form than that herein represented in order
to prevent it deflecting laterally when used as a spring and the coils would not fit
within each other as in the case of a flat steel strip but would be slightly open or
separate although not sufficiently so to allow the seeds etc. to fall out between them.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim is―
The herein described construction of flexible, extensible, and contractible delivery
conductor for agricultural drills, formed of a strip of sheet metal or wire coiled
spirally into the form of a conical tube, substantially as specified.
