PROVISIONAL SPECIFICATION.
Improvements in Chain Delivery Artificial Manure Distributors.
We, JOHN MARSHALL, Partner of the Firm of Alexander Jack & Sons, Maybole,
in the County of Ayr, North Britain, Agricultural Implement Manufacturers,
and HUGH MCFADZEAN, Manager of the said firm, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in chain delivery artificial manure
distributors.
The improvement consists in the introduction of a double set of pitch, sprocket
or pinion wheels, over and between which the chains run.
In addition to the ordinary set of pitch wheels at the back of the machine
and a roller at the front of the machine for the chains to run round, we employ
a similar set of pitch wheels at the front of the machine in place of the said
roller, by which means we obtain a more regular drive of the chains whereby a
more regular and steady spreading of the manure is effected. The chains work-
ing between the two sets of sprocket wheels being kept in perfect line. Also greater
durability of the chains is effected.

COMPLETE SPECIFICATION.
Improvements in Chain Delivery Artificial Manure Distributors.
We, JOHN MARSHALL, Partner of the Firm of Alexander Jack & Sons, Maybole,
in the County of Ayr, North Britain, Agricultural Implement Manufacturers,
and HUG MCFADZEAN, Manager of the said firm, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to improvements in chain delivery artificial manure
distributors.
The improvement consists in the introduction of a double set of pitch, sprocket
or pinion wheels over and between which the chains run.
In addition to the ordinary set of pitch wheels at the back of the machine and
in lieu of a roller at the front of the machine for the chain to run round, we employ
a similar set of pitch wheels at the front by which means we obtain a more
regular drive of the chains whereby a more regular and steady spreading of the
manure is effected.

page_text: The chains thus working between two sets of sprocket wheels are kept in
perfect line, effecting greater durability of the chains as well as more regular
distribution.
But in order that our said invention may be more readily understood and
easily carried into effect, we have hereunto appended an explanatory sheet of
drawings in which
Fig. 1 is a perspective view of a portion of a distributor showing the second or
front set of chain wheels.
Fig. 2 is a cross section of the distributor.
In the said drawings A are the wheels which we employ in lieu of a roller for
the purpose of guiding the chains. They are keyed upon the shaft B which is
carried in suitable journals or bushes secured to the end framing of the distribu-
Care the usual wheels by which the chains D are actuated. Motion is
imparted to the shaft carrying said wheels by the driving gear E in the usual
tor.
way.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
In chain delivery artificial manure distributors, the employment of two sets
of pitch or sprocket wheels one arranged at the back and the other at the front
of the machine round which the distributing chains run, whereby the chains are
driven more regularly and kept in line in their passage through the body of the
machine, ensuring a more steady and regular spreading of the manure, sub-
stantially as hereinbefore described and shewn in the accompanying drawings.
