I ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Engineer, do hereby declare the nature of this invention (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) 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 devise simple mechanism by which the
angle of all the hoes or teeth may be simultaneously altered and by which they
may also be made to form a zig-zag or double rank position; and secondly to pro-
vide simple means for connecting and disconnecting the hoes or cultivator teeth to
or from their drag bars; and it consists essentially first in connecting the drag
bars to a series of cranks set opposite to each other on a rod suspended upon arms
pivoted to the frame of the machine; the said rod being provided with mechanisin
by which it can be raised or lowered for the purpose of angling the hoes or culti-
vator teeth and also with mechanism by which the said rod may be turned on its
centre for the purpose of altering the angle of the cranks attached to it and
thereby zig-zag the hoes or cultivator teeth as required; and secondly in forming
on each hoe or cultivator tooth a plate having a T shaped projection formed on it
to fit into a slot formed in a head or plate attached to the drag-bar, and provided
with a lock for securing the hoe or cultivator tooth when its projection has been
inserted into the slot referred to substantially as hereinafter more particularly
explained.
Figure 1 is a perspective view showing a portion of the machine exhibiting the
angling and zig-zag mechanism.
Figure 2 is an enlarged detail of the block arm and attachments.
Figure 3 is an enlarged detail showing the device for securing the hoe or
cultivator tooth to its drag bar.
Figure 4 is a detail showing the lock for securing the hoe or cultivator tooth
when in position.

page_text: In Figure 1 I merely show one side of the machine entending from the side
frame A to the tongue B-the mechanism on the other side of the tongue being
exactly the same as that exhibited in the drawing.
C is the ground wheel axle suitably journalled on the frame A.
D is a rod preferably made of gas-pipe and extending from one frame A to the
corresponding frame on the other side of the machine. This rod D is braced to
the axle C by the bracket E both the axle and the rod passing through suitable
holes in the said bracket as indicated which bracket also provides means for
securing the diagonal brace F'employed in laterally strengthening the tongue B.
G is a rod to which the cranks H are rigidly attached as indicated, a drag bar I
being connected to each crank. The rod G is journalled at each end on an arm J
which is pivoted upon the frame A as shown. The rod G is further braced by an
arm K pivoted at one end to the bracket E and at the other end to the rod G.
L is a rod extending across the machine and journalled at each end on the
frame A. This rod has an arm M fixed at each end and connected to the rod G by
a link N.
O is a hand lever rigidly fastened to the rod L and connected as shown by the
link P to the rod G.
Qis a notched quadrant fixed on top of the tongue B and into which the
spring pawl of the hand lever O engages. It will thus be seen that by moving
the hand lever O the rod G may be raised or lowered as required which movement
will of course alter the angle of the hoes R causing them to take a heavier or
lighter cut according to the nature of the work required of them.
R¹ is a guide bracket fixed to the bottom of the tongue B as shown.
S is a block fitting into the guide bracket R². A hole in the centre of the
block S permits the free passage of the rod G to which rod the arm U is rigidly
fastened immediately next to the block S.
The flanges a on the block S butt against one side of the guide bracket R', and a
washer V fitting against the block S butts against the other side of the guide
bracket R' so that the said block S is prevented from having any lateral motion
and as the hub of the arm U which is rigidly fastened to the rod G butts against
the block S the said rod is braced laterally. As the rod G passes freely through
the hole in the block S and is rigidly fastened to the arm U the rod G may be
turned on its centre by the arm U and in this way the throw of the cranks H are
changed so as to move the hoes either into single or double rank as required.
To enable the driver to effect this operation the arm U is connected by the rod z
to the hand lever T which is pivoted on the tongue B and provided with an
ordinary notched quadrant as shown.
On reference to Figures 3 and 4 the plan for connecting the hoe to the drag bar
will be understood.
W represents a head or plate attached to the drag bar I as indicated.
✗ is a corresponding head or plate fixed to the hoe R.
Z is a T shaped projection fixed to the plate X and designed to slip into the
slot b made in the plate W. It will be noticed that in order to slip the pro-
jection Z into the slot b that the hoe R must be turned at right angles to its
normal position when the T shaped projection Z will pass through the slot b, on
turning the hoe back into its normal position the T forms a lock for securing the
bottom of the two plates W and X together. The top of this plate is secured by
the plate X fitting under the lip & formed on the top of the plate W. An arm e
on one side of the plate W prevents the plate X from passing it while the eccentric
stop f when turned as indicated in Figure 3 will hold the plate X from turning
back.
Although the T shaped projection Z is preferable, it will of course be under-
stood that an L shape would answer the same purpose.
The arm e which has been referred to is cast on the head W and its end projects
to a point below the lifting roller, so that the lifting chain g shall be perpendicular.
A pin his formed on the end of the arm e over which one of the links of the

page_text: chain g is slipped and a hole ; made in the hoe or head of cultivator tooth receives
the pin h when the hoe or tooth is turned into its normal position, thereby securing
the chain g on the pin h.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed I declare that what I claim is :-
1. In a cultivator having the drag bars of the hoes or teeth connected to a
pivoted rod adjustably suspended, the combination of mechanism by which the
said rod is raised and lowered for angling the teeth and mechanism for turning the
rod for zigzagging the same substantially as specified.
2. A rod G having fixed to it the cranks H to which the drag bars I are con-
nected, arms for pivotally connecting the rod G to the frame of the machine in
combination with mechanism arranged to raise and lower the rod G substantially
as and for the purpose specified.
3. The rod G having fixed to it the cranks H to which the drag bars I are con-
nected, the arms J and K for pivotally connecting the rod G to the frame of the
machine in combination with the rod L having the hand lever O rigidly fastened
to it and connected to the rod G by the arm M and link N substantially as and for
the purpose specified.
4. The rod L provided with arms M rigidly attached to it, and connected by
the links N to the rod G, in combination with the hand lever O rigidly fastened
to the rod L and connected by the link P to the rod G, the notched quadrant Q
fastened to the tongue B and providing means for holding the hand lever ○ as
specified.
5. The rod G connected to the frame A by the pivoted arm J and to the drag
bars I by the cranks H in combination with the arm U rigidly fastened to the
rod G and connected to the hand lever which is pivoted on the tongue substantially
as specified.
6. The plate or head W having an arm e on it, a pin h extending from the said
arm e to receive the chain g in combination with the hoe or cultivator tooth head
having a hole j formed in it substantially as and for the purpose specified.
