Improvements in Horse Rakes.
We ROBERT JOHN HARRIS and CLEMENT JOSEPH HARRIS trading as R. J. Harris
and Son of Phoenix Iron Works, Rugeley in the County of Stafford, Implement
Manufacturers do hereby declare the nature of our Invention and the manner in which
the same is to be performed to be particularly described and ascertained in and by the
following statemerit :-
Our invention consists of the arrangements or combinations of parts hereinafter
described for locking the tine frame of the horse rake in the position in which the tines
carried by it are lowered for use and for raising and lowering the tines and for
holding the raised tines out of action for turning the horse rake and permitting it to
travel on roads.
Our invention consists further of the arrangement or combination of parts
hereinafter described for adjusting the height and inclination of the shafts of
horse rakes.
The oscillating tine frame turns on the axle of the horse rake as usual and
is capable of a backward and forward motion through a quadrant for putting the tines
carried by it into and taking them out of action. For the purpose of locking the tine
frame when the tines are in action we use a weighted lever crossing part of the
tine frame the inner arm of the said lever being operated by the foot of the driver to
raise the outer arm. In the under side of the end of the outer arm of the locking lever is a
V-shaped notch. The back bar of the oscillating tine frame when the said frame is
turned for throwing the tines into action is brought opposite the said notch in the locking
lever and the said lever falling its notch drops upon or engages with the edge of the
said back bar and locks the tine frame with the tines in their lowered position.
•
To liberate the tine frame for lifting the tines out of action the driver depresses
by means of his foot the inner arm of the locking lever so as to raise its notched arin
from the back bar of the tine frame.
We raise and lower the tines and hold them in their raised or out of action position
by the following combination of parts.
.
To the front and middle of the horse rake a curved lever is jointed the said
lever being provided with two handles making an angle of about 45 degrees with one
another. One of these handles is used for raising the tines and the other for
depressing the tines. The lower end of the curved lever is jointed by a link to the
front bar of the oscillating tine frame. When one of the handles of the curved lever
is 'moved forward or towards the horse the tines are lowered into action and when the
other handle is moved backwards the tines are raised out of action and maintained in
that position by the action of the lever and link described. That is to say, when the
tine frame is locked the link is inclined over the tine frame and by the back motion of
the bandle; the front side of the time frame is made to descend lifting the tines out of
action and causing the link to take a nearly vertical position.
By giving the handle of the lever a further back motion, the said lever causes the
link to be moved over to the opposite side of its dead centre to that which it occupied-

page_text: when the tines were in action. By this position of the link the tines are firmly beld
in their raised or out of action position for the travelling of the horse rake when; out
of use.
For the purpose of adjusting the height of the shafts of horse rakes we use, the
following combination of parts.
The shafts turn on centres carried by short arms fixed to the front cross bar of the
horse rake and the said shifts beyond their centres carry quadrant shaped pieces
each quadrant piece being pierced with a line of holes struck from the centre on which
the shaft turns.
In each of the short arms carried by the front cross bar is a hole
opposite which one of the holes in the quadrant piece can be brought by turning the
shafts through the required angle.
In each of the holes in the short arms a sliding bolt works. The inner ends, of
these sliding bolts are so jointed above and below the centre of a lever that by the
motion of the said lever they can be simultaneously moved in opposite directions and
their outer ends either made to pass through the coincident holes in the short
arms and quadrant pieces or be withdrawn from the holes in the quadrant pieces.
this way the height and inclination of the shafts can be adjusted.
In
We will now proceed to describe with reference to the accompanying Drawings the.
manner in which our invention is to be performed.
In
Figure 1 represents in front elevation; Figure 2 in plan and Figures 3
and 4 in cross section, a horse rake containing our improvements.
Figure 3 the tine frame is represented in its lowered position for use and the locking
lever in action and in Figure 4 the tine frame is represented in its raised position
with the tines out of action for turning the horse rake and for permitting it to travel
on roads, the locking lever being in its withdrawn position. Figure 5 represents
the locking lever and a portion of the tine frame drawn to a larger scale and
Figure represents a side elevation of one of the shafts of the horse ruke and one of
the fixed arms to which the shaft is jointed drawn to a larger scale.
The same letters of reference indicate the same parts in the several Figures of the
Drawings.
a is the axle of the horse rake; bb the wheels and c the fixed frame, the latter
carrying the locking lever for the tine frame, the driver's seat and other parts; d d
is the tine frame and e are the tines the ends of the said tine frame turning on the
axle a.
The said tine frame d, d² is capable of a backward and forward motion through
a quadrant for taking its lowered position Figure 3 or its raised or out of action
position Figure 4. The tine frame d, is locked in its lowered position Figure 3
by the weighted leverf turning on the centre of the fixed frame c of the horse rake.
The shape of the weighted locking lever is best seen in the enlarged view Figure 5.
The outer arm of the locking lever is provided with a notch g for engaging with
the back. bar d2 of the tine frame d. After the tine frame d, d' has been lowered
so as to bring the tines into their acting position Figure 3 the back bar d² of the
tine frame is brought opposite the said notch g in the locking lever and the said
lever falling its notch drops upon or engages with the edge of the said back bar d
and locks the time frame with the tines in their lowered position as seen in Figures 3
and 5. Before the tine frame d, d can be lifted into the position represented in
Figure 4 it is necessary to liberate the weighted locking lever f: This is effected
by the driver depressing by means of his foot the inner arm of the locking lever so
as to raise its notched arm into the position represented in Figure 4 and thereby remove..
it from the edge of the back bar d of the tine frame d, d.
The mechanism for raising and lowering the tines and their frame and holding
them in their raised or out of action position consists of the following parts.
To the front and middle of the fixed frame c of the horse rake, a curved lever h is
jointed at the said lever being provided with two handles h³, h making the angle
with one another represented in the Drawing, the handle being used for raising the
tines and the other handle for depressing the tines. The handles h³, h' are within
reach of the driver seated on the seat i. The lower or inner end of the curved lever /
is jointed by the link-k-to the front bar of the oscillating time frame d, d². When the

page_text: handle 7, is depressed or moved forward into the position represented in Figure 3 the
tines e, e are lowered into action and when the other handle h³ is moved backwards
into the position represented in Figure 4 the tines are raised out of action and
maintained in their raised position by the lever hand link k. It will be seen by an
examination of Figure 3 that when the tine frame d d is in its lowered position and
automatically locked by the weighted locking lever f, the link is inclined over the
tine frame the position of the lever tending to hold the tine frame in its lowered
position and it will be seen by an examination of Figure 4 that by the back motion
of the handle h³ the front side of the tine frame is made to descend lifting the tines out
of action and causing the link k moving in the direction indicated by the arrow in
Figure 3, to take a nearly vertical position and to occupy the opposite side of its dead
centre to that which it occupied when the tines were in action as represented in
Figure 3. When the tine frame is in the position Figure 4 the tines e e are held
firmly in their raised or out of action position for the turning of the horse rake or the
travelling of the horse rake when out of use.
We will now describe the arrangement for adjusting the height of the shafts 1, 1 of
the horse rake :-m, m are short arms carried by and fixed to the axle a of the rake.
To the fixed short arms m, m the shafts 1, lare jointed at 12, 12 the said shafts carrying
beyond their centres, quadrant pieces m², m² (see Figure 6) provided with a line of
holes struck from the centre on which the shafts 1, 1 turn. In each of the short
arms mis a hole opposite which one of the holes in the quadrant pieces m³, m² can be
brought by turning the shafts 1, 1 through the required angle.
sliding bolts p, 1 (see
The inner ends of the
so
The shafts, are locked in their adjusted position by the
Figure 1) working in the holes in the fixed short arms m, m.
sliding bolts p, g are respectively jointed above and below the centre of the lever
that by the motion of the said lever in one or other direction they can be simultaneously
moveri in opposite directions.
ין
When the lever is moved in the direction indicated by the arrow in Figure 1 the
bolts p, q are withdrawn from the holes in the quadrant pieces m², m² of the shafts
and the said shafts are liberated and can be raised or lowered so as to adjust their
height. By then moving the lever in a direction contrary to that indicated by the
arrow in Figure 1 the two bolts p, q are simultaneously moved outwards and their
outer ends made to pass through the coincident holes in the quadrant pieces m², m² and
arms m, m and the adjusted shafts thus locked. The motion of the lever is limited
by the stop plate s.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that we
claim as our Invention of "Improvements in horse rakes:-
First The arrangement or combination of the parts of the mechanism herein
before described and illustrated in the accompanying Drawings for raising and
lowering the tines of horse rakes and for holding the raised tines out of action for the
