Improvements in Apparatus for Sowing Clover and other Seeds.
I THOMAS YATES of The Old House Balby Doncaster in the County of York
Agricultural Machinist do hereby declare the nature of this invention to be as
follows:-
:-
My present invention relates to apparatus for sowing clover and other seeds and
is applicable more especially to those kind of clover seed drills or sowers which are
arranged with Cambridge rollers in order to form seams in the soil into which the
seeds are delivered or sown and the object of my invention is to arrange means
whereby the seed may have a more uniform delivery from the seed box to attain
which I arrange a seed box of partly eliptical form in cross section and the upper
back part of which I hinge to a frame or hack which is arranged with preferably
circular seed conductors extending obliquely to the delivery tubes or seed
distributors which are carried upon the frame of the machine and are formed in
wood of section in cross sectional plan extending downwards to just above the
seams made in the soil by the rings of the Cambridge roller.
The seed box aforesaid is carried at its underside upon a shoe or fitting which
is hinged to a rack and a pinion gears with said rack and is carried upon a spindle
or shaft bearing at one end in the frame of the machine and at the other extending
through the back and receiving a suitable hand wheel or handle so as to be easily
operated by the driver. Within the said seed box and near its back part is
arranged a seed barrel which consists in the usual manner of a number of discs
having the ordinary seed cups made with or attached thereto. This seed barrel is
secured to a horizontal shaft which is carried upon two brackets one at each end
thereof and arranged outside and independent of the seed box. The said seed
barrel shaft is driven by change gear wheels the shaft carrying the counter wheel
being driven direct from the Cambridge roller axle by a chain. The countershaft
spur wheel is arranged with a ratchet which together with said spur wheel is carried
loosely on said counter shaft. The driven chain wheel is secured to the said
counter shaft and has attached to it a suitable pawl which meshes with the ratchet
on the spur wheel excepting when otherwise thrown out of gear. The throwing in
and out of gear of the said pawl is preferably performed by means of a suitable
rod made with a key formed end and an opposite handle or cross piece and it bears
in suitable fixings and when turned in one direction throws the pawl away from the
ratchet and when turned in the opposite direction it allows a spring to force the
pawl into gear with the ratchet by this arrangement it will be obvious that
the seed barrel can only revolve when the pawl is in gear with the ratchet. As the
brackets which carry the axle of the seed barrel are on the outside of each end of
the seed box a suitable opening is arranged at each said end for the said axle to
pass through. The seed barrel is arranged so that the cups dip into the seed box
at the back part thereof which is struck to a radious at this part in cross section to
suit the radious of the periphery of said cups. As the seed barrel moves the cups
round the seed is taken thereby from the seed box and delivered upon a tray or
trough which is fixed at an inclination and is closed at one end and has suitable
perforations over the seed delivery tubes or conductors in the back frame of the
apparatus. I prefer in this apparatus to arrange a seat over or at the back of the
apparatus for the driver to be seated upon and to arrange a chain harrow at

page_text: the back of machine to cover up the seed and I arrange a suitable cover for the
seed box as will be well understood.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Sowing Clover and other Seeds.
I THOMAS YATES of The Old House, Balby, Doncaster, in the County of York
Agricultural Machinist, 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 :-
My present invention relates to apparatus for sowing clover and other seeds, and
is applicable more especially to those kind of clover seed drills, or sowers, which
are arranged with Cambridge rollers in order to foorm seams in the soil into which
the seeds are delivered or sown, and the object of my invention is to arrange
means whereby the seed may have a more uniform delivery from the seed box, to
attain which I arrange my improvements and work the same substantially as
described with reference to the accompanying drawings in which
Fig. 1 is a side elevation of a sowing machine or apparatus constructed with my
present improvements,
Fig. 2 is a plan of same, with the seed box cover partly removed, and
Fig. 3 is a sectional elevation taken on line a a of Fig. 2.
Similar letters of reference denote corresponding parts in each view.
I arrange the seed box B of partly eliptical form in cross section as shown.
Figs. 1 and 3, and the upper back part of which I hinge to the ordinary seed
frame or back C which has the seed conductors c' extending obliquely-and
preferably V shape in cross sectional plan-downwards to just above the seams
made in the soil by the rings of the Cambridge rollers D. My improved seed
box B is carried at its underside upon a shoe or fitting E which is hinged to a
rack G, and a pinion h¹ gears with said rack G and is carried upon a spindle or
shaft H, which latter bears at one end in a bracket h² which is fixed to the shaft
or centre pole S of machine, and at the other end bears in frame C and extends
through the same at the back, and receives a suitable hand wheel J so as to be
easily operated by the driver who follows the machine. Within the said seed box B
is arranged the ordinary seed barrel K which consists in the usual. manner of a
number of discs having seed cups k' made with or attached to them this seed
barrel K is secured to a horizontal shaft A which is carried upon or bears in two
fixed brackets C' see Figs. 1 & 2 and at each end thereof and which are secured to
or made in one with part of the frame C and are outside and independent of the
seed box B. The seed box B receives an ordinary cover ³ the ends of which are
left open to allow the shaft k² to pass through to its bearings. The shaft k² is
driven by change gear wheels m & m². The shaft n which carries the counter
wheel m is driven direct from the shaft d' of the Cambridge roller D by chain
gearing d as shewn in Fig. 1. The said shaft n² is carried in an adjustable arm n³
having a slot n so that the radial position of the change wheel m may be fixed to
suit the size of gearing required.
The wheel m may where desired be arranged with a ratchet wheel either made
with it or secured at its side and they both may be carried loosely upon the counter
shaft n². The driven chain wheel is secured to the shaft n² and may have attached
to it a pawl which gears with said ratchet excepting when otherwise thrown out
of gear by any suitable means, by this arrangement it will be obvious that the
seed barrel can only revolve when the pawl is in gear with the ratchet wheel. I
do not consider it necessary to illustrate this pawl arrangement as it is only an

page_text: ordinary driving gear which may or may not be used with my invention. The
seed barrel B is arranged so that the cups k¹ dip into it at the back part thereof,
which latter is struck to a radious at this part in cross section to suit the radious
of the periphery of the barrel K or outside of cups as shown by dotted or
broken lines at Fig. 3 which broken lines show the position of the seed box B when
all the seed is about discharged therefrom and the full lines show the position of
the seed box B when full of seed. As the barrel K moves round the cups k¹, the
seed is taken thereby from the seed box B and delivered into the conductors c¹ and
falls through the lower ends thereof into the seams made in the soil by the Cambridge
roller D. A seat for the driver may be arranged over or at the back of the apparatus
and a chain harrow placed also at the back in order to cover up the seed
immediately it is sown. It will be obvious that as the seed box B is swivelled or
pivotted at 6' and is independent of the shaft which latter is supported in the
fixed brackets the said box B can be adjusted radially whilst the shaft k¹ remains
stationary and the ends of the cover ³ being open the seed box ends will not come
in contact with said shaft A².
I would have it understood that my invention as described and illustrated
essentially consists in arranging the seed box B that it may be easily elevated
radially so that cups k² get further into the same as the seed diminishes and
consequently a uniform delivery of the seed from the box B is obtained,
therefore
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In apparatus for sowing clover or other seeds the use of a seed box B
pivotted at b and arranged to be lifted or lowered radially substantially as
described and illustrated.
2. In apparatus for sowing, clover or other seeds the combination of a seed
box B made to shape shown and hinged or pivotted at the back part thereof with a
hinged rack & pinion shaft H and hand wheel J substantially as described and
illustrated and for the attainment of the object specified.
3. The combination of a seed box B hinged or pivotted at 6' with mechanism as
illustrated or its equivalent for lifting it towards or lowering it away from the
seed cups k' substantially as described.
