Improvements in Seeding Machines.
A communication from THOMAS HENRY NOXON, of the Town of Ingersoll, in the
County of Oxford, in the Province of Ontario, Canada, Manufacturer of
Agricultural Implements.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E,
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:-
The object of the invention is first to construct that portion of the frame from
which the drag-bars are suspended in a simple cheap and light manner; secondly to
provide easy means for adjusting the drag bars to bring them closer to each other or
further apart in order to enable the drill rows to be made any desired distance apart;
and thirdly to provide simple means for adjusting the teeth or hoes on their drag bars
to any desired angle to regulate the depth at which they will enter the soil; and it
consists essentially first of a drag bar shaft connected at each end to the axle-bracket
by two bars one extending horizontally to the base of the axle-bracket and the other
diagonally to an arm extending from the said bracket, the said shaft being journalled
in a bracket fixed to the bottom of the tongue; secondly of drag bar clips fitted
onto a drag bar shaft having a longitudinal groove formed in it to receive a rib
formed on the journal surface of each clip in order that the said clips may be
independently adjusted longitudinally upon the said shaft and at the same time be held
from revolving on it; and thirdly in the peculiar formation of the drag bar head
and projections extending from the drill hoe or cultivator tooth by which the angle
of the said drill hoe or tooth may be readily adjusted without removing a bolt.
Fig. 1 is a perspective view of that portion of the frame to which the drag bars
are connected.
Fig. 2 is a detail of one of the drag bar clips.
Fig. 3 is a perspective view of the drag bar head and top of the drill hoe or
cultivator tooth.
Fig. 4 is a sectional elevation of the same parts.
Fig. 5 is a detail of the mechanism for locking the drill-hoe or cultivator tooth in
position.
Fig. 6 is a detail of lifting chain connection.
A is the drag bar shaft supported at each end by two bars B and C, the bar B
extending horizontally to the bottom of the axle bracket D while the bar C extends
diagonally to an arm E projecting from and formed upon the axle-bracket D, thus
constituting a strongly braced support for each end of the drag-bar shaft A. A
bracket R fixed to the bottom of the tongue S forms a bearing for the centre of the
shaft A and midway between this counter bracket and the ends of the shaft A, are
preferably provided stiffening bars T.
With the view of enabling an easy longitudinal adjustment of the drag bars F
a longitudinal groove a is made in the drag bar shaft A and on the journal
When the
surface of each drag-bar clip G is formed a rib 6 to fit into the groove a.
nuts H which hold the cap of the clip in position are tightened the said clip G is
held rigidly to the drag bar shaft A and by loosening the said nuts the said drag-bar
clips may be independently adjusted longitudinally upon the drag-bar shaft A and
held in any desired position by simply retightening the said nuts. Of course the same
effect will be produced by making a rib on the drag-bar shaft or making the drag-
bar angular in cross section in order to prevent the clip from revolving on the drag-bar
shaft, while permitting it to be adjusted longitudinally. By thus making the drag-
bar clips adjustable upon the drag-bar shaft the drag-bars may be moved closer to.

or teeth of his machine to make the drill-rows any desired distance apart. The hand-
lever I is suitably supported on a bracket fixed to the tongue of the machine and is
connected by the rod J to the crank K. which is fixed to the drag-bar shaft A. It
follows therefore that the movement of the hand-lever I will cause the drag-bar
shaft A to revolve and as the drag-bars are alternately connected to their respective
clips on opposite sides of the drag-bar shaft A the rolling of the said drag-bar shaft
will cause the desired zig-zagging of the teeth or hoes. As the shaft A cannot be
raised or lowered for the purpose of altering the angle of the teeth or hoes it is
necessary that the teeth or hoes should be connected to their respective drag-bars in
such a manner that their angle may be readily altered. This is accomplished in a
simple manner and without the necessity of removing a single bolt.
Un reference to sheet 2 of the drawings the details of construction of this; portion of
the invention will be found fully illustrated.
I is the drag-bar head pivoted on the end of the drag-bar and held in position by
the spring dog M. A notched projection N extends from the top of the head L
and from the base of this projection the face of the head is shaped as indicated to
receive the faces of the projections O P. formed on the head of the drill-hoe or
cultivator tooth. The projection O is shaped as indicated to fit into any of the notches
formed on the projection N while the projection P is merely the base of the
T-bolt which is designed to fit into an elongated slot U formed in the drag-bar
head as indicated. In order to insert this T-bolt Qin tlie said slot it is necessary
to turn the tooth or hoe in a horizontal position and when it resumes its normal
position the T-head of the said bolt Q extends across the slot and holds the
projection Pagainst the head I. When the T-bolt Q is inserted in the slot U and
the tooth or hoe swings around to resume its normal position the spring bolt V is
held clear of the slot Ú by the hand so as to permit the T-bolt Q to be at or near
the bottom of the slot U in order that the projection O may clear the lip d formed
on one side of the notched projection N.
:
When the tooth or hoe is adjusted to the desired angle it is. raised up so as to force
the projection O into the desired notch in the projection N which will hold if in the
said position. When thus raised up the spring bolt V springs out under the T-head of
the bolt Q thus locking the said bolt and preventing the projection O froin falling out
of its notch.
From this description it will be seen that it is merely necessary to push the spring
bolt. V clear of the T-head of the bolt Q when the projection O may be dropped clear
of the notched projection N and moved so as to come opposite to the particular notch
which will hold it in the desired new position.
:
With the view of providing simple means for the purpose of detachably connecting
the lifting chains to their respective drag-bars an arm W which extends back onto
one side of the drill-hoe or tooth head is formed upon the drag-bar head L. On the
side of the arm W next to the face of the tooth or hoe is formed a fork X into which
one of the links of the chain Y..is inserted. In order to retain the chain in this fork
a flange Z is formed on the face of the hoe or tooth head which projects over, the
forked end of the arm W when the tooth or hoe is fixed to the drag-bar head L.
With the view of permitting the easy. rocking of the head of the tooth or..hoe
while being adjusted to the different angles the face of the projection P is convexed
or that portion of the drag-bar. head L' against which the said projection fits or both
the said surfaces may be convexed.
With the view of preventing the lateral movement of the projection O'in the notch,
the hip d already described can either be provided on one side of the notched
projection N, or they might be placed on both sides; or instead of the lip being
formed on the notched puojection N a lip could be formed on one or both sides
of the projection O.
"
I have spoken of the bolt Q as being T-headed. It will of course be understood
that an L-headed bolt would answer quite as well-in fact a bolt with a head of
any form which will prevent it passing a slot made to receive its shank would

page_text: answer. If a round-headed bolt were used a round hole would of course have to be
made near the bottom of the slot U. All the other parts would work exactly the
same except that it would not be necessary to turn the hoe or tooth in a horizontal
position in order to form the connection between it and the drag-bar head.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by my
foreign correspondent, I declare that what I claim is ;-
