Improvements in Horse Hoes.
1 GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co., The
General Patent Office, No. 4, South Street, Finsbury, in the County of London,
Patent Agents, do hereby declare the nature of this invention (a communication
to me by The Cockshutt Plow Company Limited, a company duly incorporated
under the Joint Stock Company Act of the Dominion of Canada, of Market
Street, in the City of Brantford, in the County of Brant, in the Province of
Ontario, Canada, Manufacturers,) 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 improvements in horse-hoes and the object of the
invention is first to provide means whereby the concavo-convex discs used in
cultivators may be adapted to a horse hoe, secondly to provide a simple means
whereby the leading wheel may be raised or lowered from the rear of the machine
near the handles so as to regulate the depth that the teeth or blades shall extend
into the ground when cultivating it--thirdly to provide a simple means whereby
the distance apart of the side bars of the frame may be readily altered in order to
increase or diminish the distance apart of the blades or discs for the purpose of
making the furrows of a greater or less distance from each other, and it consists
essentially-first-of providing bent arms adjustably secured in position to the side
bars, and journalling the concavo-convex discs upon a suitable stud passing through
the lower end of the vertical portion of the bent arms and secured in the same-
secondly in journalling the leading wheel in the lower end of a forked arm which
is pivoted intermediately on the frame and connected at the top by a double bar to
a lever journalled on the rear of the central bar of the machine and having spring
actuated plunger designed to co-act with a toothed quadrant secured at the rear
end of the central bar, and-thirdly-in providing upon the central bar of the
frame a sliding block with two lateral slotted extensions, one on each side, into
which extend bosses on the end of the pivoted bent levers journalled in a base
plate secured to the central bar, the opposite end of the levers being pivotally
connected by links to the end of the side bars, and the sliding block being con-
nected by a rod to a lever provided with a spring plunger designed to co-act with
a quadrant, as hereinafter more particularly explained.
Fig. 1, is a perspective view of my horse hoe showing the means by which the
discs are secured in position and the means of adjustment of the leading wheel and
of the side bar to the frame.
Fig. 1 is an enlarged detail showing the manner in which the hoe is attached to
the central bar.
Fig. 2, is an enlarged detail showing the means whereby the bent arms, in the
ends of which the discs are journalled, are adjusted.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A, is the central bar of the machine, and, B, the side bars which are pivoted at
the front on the outer ends of the cross pieces, C, which are secured to the central
bar by the bolts, c. D, are the concavo-convex cultivator discs. The discs, D,
are journalled upon the studs or bolts, d, which pass through the lower ends of the
vertical portion of the bent arms, E. The upper horizontal end of each bent
arm, E, extends into a recess, f, made in the face of the toothed segment, F. The
the
teeth of the segment, F, engage with corresponding teeth, g, formed on

page_text: block, G. The block, G, is secured on the side bar by the bolts, g¹, see Fig. 2,
and the teeth of the face-toothed segment are held in engagement with the teeth, g,
by means of the staple bolt, H, the two members of which pass through the
recesses, g², cut in the inner face of the block, G, and are held in position at
the top by nuts, h. By loosening these nuts, and transferring the position of the
segment in reference to the teeth g the position of the discs may be changed to any
angle desired.
I is the leading wheel journalled in the end of the forked arm J which is pivotted
on the bolt extending through the forwardly projecting lugs c¹ of the upper cross
piece C.
K is a double bar pivotally connected at the front end to the top of the forked
arm J and at the rear end of the lever L which is pivotted at the rear of the
central bar A and has a spring actuated plunger 7 which is manipulated in the usual
manner so as to engage with the notches of the toothed quadrant secured on the
end block A bolted to the rear end of the central bar A.
M are the ordinary handles which are supported at the rear ends by the braces m
upon the rear end of the central bar A. The front ends of the handles are connected
in the usual manner by the bolt m' to the central bar A.
I have shown in the drawing one hoe N secured to the central bar A by its
shank N' which as shewn most clearly in Figure 1 is grasped by a saddle
bracket N, having lugs n having holes through which pass the ends of the clip
bolt n'. The ends of the bolt have nuts screwed on to them so as to firmly grasp
the central bar. A laterally projecting lug n² extends from the rear end of the
bracket over the shank, so as to withstand the rearward pressure of the shank when
the hoe is working. It will be seen by the construction adopted that the shank can
be frictionally held to the central bar in any desired position. It will of course be
understood that I might use all the usual blades or ploughshares, although I
specially show the discs in order to describe and claim their particular method and
application to my machine.
I shall now describe the means whereby the side bars are adjusted for the
purpose hereinbefore set forth. O, is a sliding block, which is supplied with two
lateral slotted extensions, o. P, is a bent lever which is journalled in the
outwardly and upwardly extending disc-shaped portions, q, of the base plate, Q.
which extends laterally from each side of the central bar, A, and is secured thereto
by means of the bolts, q', extending through the lugs, 2 on each side of the central
bar and through the central bar, A. both in the front and rear of the base plate.
2, are bosses formed on the inner ends of the levers, P, and extending upwardly
into the slotted extensions, o. R, are links which are pivotally connected to the
outer ends of the bent levers, P. One of the members of the staple bolt, H,
passes through the link, R, at its outer end. S, is a rod which has two bent or
hooked ends, one of which passes through the lug, o¹, forming part of the block O,
and the other through the lug, t, forming part of the lever, T. The lever, T, is
supplied with the usual spring plunger, t, which is manipulated in the ordinary
manner so as to cause it to engage with one of the notches in the toothed
quadrant, T', which is suitably secured to the central bar, A.
In order to adjust the width of the ends of the pivoted side bars from each other
and thereby regulate the distance apart of the discs or blades, as the case may be,
it will be readily seen that I have merely to manipulate the lever rearwardly so as
to widen the distance apart of the rear ends of the side bars, B, and bring the
lever, T, forward in order to bring them closer together. In whichever position
they may be bought it will be easily understood that the side bars will be
securely held. in position. I may at the same time, if necessary, by simply
loosening the staple bolts and changing the position of the segments, F, as the
teeth, g, formed in the block, G, alter the position or angle of the discs or blades
laterally.
A horse hoe provided with discs herein before described may be used very advan-
tageously for the purpose of hilling or hoeing for taking the earth away from

page_text: plants instead of the common hiller board, blade, or other points now commonly in
use for this purpose. By means of the adjustment shown for the discs they may be
readily placed at any angle it is necessary for the purpose of hilling or hoeing up
or they can be reversed if necessary and used for removing the earth from young
plants or roots.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with a horse hoe or cultivator of concavo-convex discs
adjustably secured to the same in any desired position, as and for the purpose
specified.
2. In a horse hoe or cultivator the combination with the central bar and side
