I, FREDERICK CROMPTON LAKE, of Rayne Foundry, Rayne, in the county of Essex,
Agricultural Implement Maker, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in that class of horse hoes which have one
or two rows of hoes arranged at the rear thereof and which are known in the trade
by the term "link lever horse hoe." The principal objects of such improvements,
are, to effect the steering of the frame carrying the hoes without interfering with the
line of draft of any part of the main body of the machine, to change the pitch of
the hoe blades, to alter the.depth of the hoe blades, and to raise the hoes clear of the
ground. The construction of the machine is such that the said objects can be effected
in an easy and convenient manner by the attendant at the rear of the machine whilst
the latter is travelling.
The machine is constructed in two principal parts, first the main frame, and, secondly,
the hoe frame. The main frame which carries the bearings of the travelling wheels, has
at the back two cross rods or tubes situated one above the other, and on the lower rod or
tube are arranged the bifurcated ends of two arms projecting from the hoe frame, the
said rod or tube passing between a pair of rollers mounted between the ends of each
of the said arms, the ends of two arms, also extending from the hoe frame, are arranged
over the upper rod or tube, a friction roller, on a rod connecting the ends of the two
last mentioned arms to the bifurcated ends of the other arms bearing against the
inner face of the said rod or tube, this will prevent the arms from falling outwards
and will, at the same time, allow them to be moved inwards when it is desired to
raise the hoes free from the ground as hereinafter described. The steering rod is
pivoted at its inner end to the main frame and passes through a link or socket on the
hoe frame, so that when it is moved to the right or left, the before mentioned rollers
sliding along the rods at the end of the main frame, the hoe frame will be moved in
a corresponding direction and in a line parallel to the axle of the machine.
The improvements for effecting the alteration in the pitch of the hoe blades are as
follows. A lever, the outer end or handle of which projects from the rear of the
machine, is keyed or pinned to a cross bar or tube carried at the upper part of the

main frame, the said lever is provided with a spring tooth or catch which gears into
a quadrant also attached to the main frame of the machine. To the bar or tube lastly
mentioned is attached a second lever the outer end of which is pivoted to a lever
connected to the upper rod or tube at the rear of the main frame so that the lever or
handle being depressed the said upper rod or tube will be drawn inwards and the
hoe frame turned on the lower rod or tube and the hoes are raised, and, when the
said lever or handle is raised, the action of the various parts will be reversed.
The alteration in the depth of the hoes is effected by the following means.
is pivoted at each side of the upper part of the main frame. The rear ends of the
said levers are connected by chains with the lower bar at the rear of the main frame
and chains attached to the opposite ends of the levers are respectively connected to
the peripheries of discs or drums on a cross bar or tube mounted in bearings at the
front of the machine. The last mentioned bar or tube has keyed thereon a toothed
wheel, into which gears a worm on a rod the outer end of which extends to the rear
of the machine in a convenient position to be turned by the attendant. When the
said rod is turned in one direction the chains at the fore ends of the levers will be
further wound on to the peripheries of the discs or drums and the hoe frame thereby
raised, whilst on being turned in the opposite direction the chains will be more or
less disengaged from the said peripheries and the hoe frame will be consequently
allowed to descend. The rear ends of the said levers are hooked so that any links of
the chains connecting them to the hoe frame can be placed thereon, this will allow of
the chain at either side or the chains at both sides being shortened or lengthened in
order to keep the hoe frame level with the ground when the surface being passed
over is uneven.
For the purpose of raising the hoe frame clear of the ground a handle is attached
to the back thereof and on the same being raised by the attendant, the hoe frame will
be turned on the lower bar or tube at the back of the main frame, the inner end of
the upper arm of the hoe frame, only having one roller situated as herein before
described, moves inwards until a shoulder on a lever loosely pivoted thereto drops
over the upper rod or tube at the back of the main frame and serves to retain the hoe
frame in its raised position. When it is desired to release the latter the last
mentioned lever is disengaged and the frame descends by its own weight or its
descent may be controlled by means of the last mentioned handle.
The hoe stalks are formed of U shaped bars of steel and are pivoted to small bars
or links the opposite ends of which are pivoted to similar U shaped bars clamped or
screwed on to triangular bars forming part of the hoe frame.

page_text: I, FREDERICK CROMPTON LAKE, of Rayne, in the County of Essex, Agricultural
Implement Maker, 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 said invention relates to improvements in that class of horse hoes which have
one or two rows of hoes arranged at the rear thereof and which are known in the
trade by the term "link lever horse hoes." The principal objects of such improve-
ments are, to effect the steering of the frame carrying the hoes without interfering
with the line of draft of any part of the main body of the machine, to change the
pitch of the hoe blades, to alter the depth of the hoe blades, and to raise the hoes
clear of the ground.
The construction of the machine is such that the said objects can be effected in an
easy and convenient manner by the attendant at the rear of the machine whilst the
latter is travelling.
The following is a description of the machine, constituting the subject of this
invention, with reference to the accompanying drawings, in which the same letters of
reference indicate like parts in all the Figures. Figure 1. is a top view of the
machine, Figure 2. a side view with one wheel removed, Figure 3. a back view, of the
same, and Figures 4. and 5. are respectively enlarged side elevation and top view of
a hoe and stalk and link carrying the same.
The machine is constructed in two principal parts, first, the main frame A., and
secondly, the hoe frame B. The main frame A., which carries the bearings of the
travelling wheels, has at the back two cross rods or tubes a. a¹ situated one above the
other, and carried by the arms or connections H., and, on the lower rod or tube a.,
are arranged the forked ends of the two arms b. 61 projecting from the hoe frame, the
said rod or tube a. passing between a pair of rollers mounted between the ends of
each of the said arms, the ends of two arms 66 also extending from the hoe frame,
which connects
are arranged over the upper rod or tube a' a friction roller on a rod
the ends of the arms to the forked ends of the arms b. b1, bearing against the
inner face of the rod or tube a¹ thereby preventing the arms 636 from falling out-
wards, and, at the same time, allowing them to be moved inwards when it is desired
to raise the hoes x. free from the ground, as hereinafter described. The steering rod d.
is pivoted at its inner end to the main frame and passes through a link or socket d'
on the hoe frame, so that when it is moved to the right or left the before mentioned
rollers sliding along the rods a. a¹ the hoe frame will be moved in a corresponding
direction and in a line parallel to the axle of the machine.
The improvements for effecting the alteration in the pitch of the hoe blades are
as follows. A lever e, the outer end or handle of which projects from the rear of the
machine, is keyed or pinned to a cross bar or tube e' carried at the upper part of the
main frame, the said lever is provided with a spring tooth or catch which gears into

page_text: a quadrant e also attached to the main frame of the machine. To each end of the
bar or tube e¹ is attached a second lever e³ (Figure 3) the outer end of which is
pivoted to a lever et connected at one end to the upper rod or tube a¹, so that, on the
lever or handle being depressed, the said upper rod or tube a¹ will be drawn inwards
and the hoe frame turned on the lower rod or tube a. whereby the rear ends of the
hoes are raised, and, when the said lever or handle e. is lifted or raised, the action of
the various parts will be reversed.
The alteration in the depth of the hoes is effected by the following means. A leverf.
is pivoted at each side of the upper part of the main frame. The rear ends of the
said levers are connected by chains with the lower bar a, and chains, attached to the
opposite ends of the levers, are respectively connected to the peripheries of discs or
drums f¹ on a cross bar or tube mounted in bearings at the front of the machine.
The last mentioned bar or tube has keyed thereon a toothed wheel f³ into which
gears a worm on a rod f* the outer end of which extends to the rear of the machine
in a convenient position to be turned by the attendant. When the rod ft is turned
in one direction the chains at the fore ends of the levers f. will be further wound on
to the peripheries of the discs or drums f¹ and the hoe frame thereby raised, whilst
on being turned in the opposite direction, the chains will be more or less disengaged
from the said peripheries and the hoe frame will be consequently allowed to descend.
The rear ends of the said levers f. are hooked so that any links of the chain
connecting them to the hoe frame can be placed thereon, this will allow of the chain
at either side or the chains at both sides being shortened or lengthened in order to
keep the hoe frame level with the ground when the surface being passed over is
uneven.
For the purpose of raising the hoe frame clear of the ground a handle g. is attached
to the back thereof and on the same being raised by the attendant, the hoe frame
will be turned on the lower bar or tube a. the inner ends of the upper arms b³ of
the hoe frame only having one roller each situated as hereinbefore described, move
inwards until a shoulder on a lever loosely mounted on the cross bar h. carried by
the arms b² 63 drops over the upper rod or tube a¹, and thereby prevents the backward
movement of the latter and serves to retain the hoe frame in its raised position.
When it is desired to release the latter the last mentioned lever h¹ is desengaged and
the frame descends by its own weight, or, its descent may be controlled by means of
the last mentioned handle.
The hoe frame is shown in the raised position by dotted lines in Figure 2.
The hoe stalks i. are formed of U-shaped bars of steel and are pivoted to small bars
or links . the opposite ends of which are pivoted to similar U-shaped bars m. clamped
or screwed on to triangular bars n. forming part of the hoe frame. The arrangement
of the hoes carried by links in this manner is not claimed, but great advantage is
obtained by constructing the stalks i. and bars m. of U-shaped metal, instead of
making them in the ordinary form.
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 :-
:-
First. In horse hoes of the nature hereinbefore referred to, connecting the hoe
frame with the main frame by means of the arms b. b' and 62 3 (the ends of which
are provided with rollers) arranged in connection with the rods or tubes a. a¹ of the
main frame, substantially as hereinbefore described and shown in the accompanying
drawings.
Secondly. In hoe frames of the nature hereinbefore referred to, the arrangement
of the steering rod d. pivoted to the main frame and passing through a link or socket d
carried by the hoe frame, substantially as hereinbefore described and shown in the
accompanying drawings.
Thirdly. In horse hoes of the nature hereinbefore referred to, the combination of
the lever e,
the cross bar or tube e³, the quadrant e³, the levers es and e¹ and the rod
or tube a, the same being arranged in connection with the main frame and hoe frame,

page_text: substantially as, and for the purpose, hereinbefore described and shown in the
accompanying drawings.
Fourthly. In horse hoes of the nature hereinbefore referred to, the combination and
arrangement of the levers f, discs or drums f¹ and toothed wheel f³, on cross bar or
tube, and the worm rod, the whole being arranged and connected in conjunction
with the main frame and hoe frame, substantially as, and for the purpose, hereinbefore
described and shown in the accompanying drawings.
