page_text: I, JULIEN EMILE THOMÉ of Nouzon (Ardennes) France, Implement Maker, do
hereby declare the nature of this Invention to be as follows:-
My improvements in horse-rakes relates more particularly to the mechanism for
throwing up and letting down the tines whereby a quick action of the machine is
obtained.
Reference is to be had to the accompanying drawings forming part of this
Specification wherein Figure 1 represents a perspective view of the rake, Figure 2
shews the rake mechanism, the tines being in work, Figure 3 is a detail face view of
the mechanism for holding the tines raised when out of work, Figure 4 is a detail
sectional elevation of the tine-raising mechanism and Figure 5 is a plan of the same,
Figure 6 represents the rake mechanism, the tines being thrown up for travelling
Figure 7 is a detail face view of the device for holding the times in the raised position
when out of work, Figure 8 is a detail view of a tine-socket made in two parts. The
same letters of reference indicate the same parts in all the figures.
Each of the tines a of the rake is fixed in a socket 6 loose upon a shaft c so that
all the tines rest on the axle d of the travelling wheels R. The shaft c is fixed in the
frame e the side bars of which have collars f pivoting loosely on the axle d. The hub
of each carrying wheel is provided with a ratchet wheel g with which engages a pawl h
mounted on frame e for the purpose of throwing up the tines, the pawl being
disengaged when the tines are in work. The pawls are disengaged by means of
forked levers i embracing the pawls and keyed on the ends of a shaft j turning in ears /
on frame e. The shaft has keyed on it a sleeve which is notched as at ¹ to receive
the end of the short arm m of a lever of the first order pivoted at n and counter-
weighted at m¹. When the rake is in work the counterweighted end m¹ of the lever
rests on the axle d, as shewn in Figure 2, and the short arin m by engaging in the
notch throws up the levers i which disengage the pawls h.
To discharge the hay collected by the tines the driver seated at o depresses the
pedal p connected by link q to a three-armed lever 77 on a shaft X which being
thereby oscillated raises the couterweight m¹ through the links and allows the pawls
to engage with the ratchet wheels which by the rotation of the carrying wheels cause
the rake frame e to be carried around the axle d in the direction of the arrow Figure 2
so as to throw up the tines to the position shewn in Figure 6. By this movement
the hay collected by the tines is discharged by meeting the cross bars carried by the
axle d and the rear frame t as usual in horse-rakes. The frame e after being operated
by the carrying wheels as above described finally assumes such a position that the
pawls h are again disengaged by the forks i from the ratchets g so that the frame
being no longer held up the tines will resume their position as represented in Figure 2.
To enable the tine-raising mechanisin to be operated from the rear of the machine, a
pull cord u with handle vis provided for actuating the rock lever r. The tines when
thrown up for travelling are retained by an arm 1 of the frame engaging a latch x
jointed to a slider y caused to move up and down in a guide by a lever cam z as shewn

in Figure 6. For automatically engaging the arm 1, the lever cam z is operated to
ower the latch whereupon the arm 1 will slip past the latch when the tines are
thrown up and be there retained, as shewn in Figure 6. To lower the tines the arm 1
is released by raising the latch x hy means of the cam lever z.
The rake is provided with a rearwardly extending lever 2 by means of which when
the machine is stationary the attendant walking behind the machine can raise or
lower the tines and engage or disengage the lever with or from the latch and whereby
he can facilitate the turning of the machine by the horse. In the event of the sudden
backing of the horse which would be liable to bend or break the tines, the same lever
can be used for raising and supporting the tines some inches above the ground. This
raising of the tines may also be performed from the seat with the aid of pedal P
Figure 1 as a substitute for lever 2.
Figure 8 represents a tine socket 6 made in halves united by the shank of the
tine made of 1, section engaging by its flanges with the two parts of the socket which
are correspondingly shaped as shewn at a and to which the tine is secured by a bolt 4.
These divided sockets enable renewals to be easily effected without risk of breakage
which is liable to happen in dismounting the machine for the purpose as heretofore
necessary, such breakage often resulting from the bending of the tine carrying rod
which has become rusted from exposure.
I, JULIEN EMILE THOME of Nouzon (Ardennes) France, 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 improvements in horse rakes relates more particularly to the mechanism for
throwing up and letting down the tines whereby a quick action of the machine
is obtained.
Reference is to be had to the drawings accompanying my Provisional Specification
wherein Figure 1 represents a perspective view of the rake, Figure 2 shews the rake
mechanism, the times being in work. Figure 3 is a detail face view of the mechanism
for holding the tines raised when out of work. Figure 4 is a detail sectional
elevation of the tine-raising mechanism and Figure 5 is a plan of the same. Figure 6
represents the rake mechanism, the tines being thrown up for travelling. Figure 7
is a detail face view of the device for holding the tines in the raised position when
out of work. Figure 8 is a detail view of a tine-socket made in two parts. The same
letters of reference indicate the same parts in all the figures.
Each of the tines a of the rake is fixed in a socket bloose upon a shaft c so that all
the tines rest on the axle d of the travelling wheels R. The shaft c is fixed in the
frame e the side bars of which have collars fpivoting loosely on the axle d. The hub
of each carrying wheel is provided with a ratchet wheel g with which engages a pawlh
mounted on frame e for the purpose of throwing up the tines, the pawl being
disengaged when the tines are in work. The pawls are disengaged by means of
forked levers i embracing the pawls and keyed on the ends of a shaft j turning in
ears k on frame e. The shaft j has keyed on it a sleeve which is notched as at 1 to
receive the end of the short arm m of a lever of the first order pivoted at n and

page_text: counterweighted at m'. When the rake is in work the counterweighted end m¹ of
the lever rests on the axle d, as shewn in Figure 2, and the short arm m by engaging
in the notch 1 throws up the levers which disengage the pawls h.
""
To discharge the hay collected by the tines the driver seated at o depresses the
pedal p connected by link q to a three-arined lever which being thereby oscillated
raises the counterweight m¹ through the link 8 and allows the pawls to engage with
the ratchet wheels which by the rotation of the carrying wheels cause the rake frame e
to be carried around the axle d in the direction of the arrow Figure 2 so as to throw
up the tines to the position shewn in Figure 6. By this movement the hay collected
by the tines is discharged by meeting the cross bars carried by the axle d and the
rear frame t as usual in horse rakes. The frame e after being operated by the carrying
wheels as above described finally assumes such a position that the pawls h are again
disengaged by the forks i from the ratchets g so that the frame being no longer held
up the tines will resume their position as represented in Figure 2. To enable the
tine-raising mechanism to be operated from the rear of the machine, a pull cord "
with handle v is provided for actuating the rock lever . The tines when thrown up
for travelling are retained by an arm 1 of the frame engaging a latch a jointed to a
slider y caused to move up and down in a guide by a cam 3 operated by a lever
handle 2, as shewn in Figure 6. For automatically engaging the arm 1 the lever
cam 3 is operated to lower the latch whereupon the arm I will slip past the latch x
when the tines are throwu up and retained, as shewn in Figure 6. To lower the
tines the arm 1 is released by raising the latch x by means of the cam 3 and
lever z.
The rake is provided with a rearwardly extending lever 2 by means of which when
the machine is stationary the attendant walking behind the machine can raise or
lower the tines and engage or disengage the lever with or from the latch and whereby
he can facilitate the turning of the machine by the horse. In the event of the
sudden backing of the horse which would be liable to bend or break the tines, the
same lever can be used for raising and supporting the tines some inches above
the ground. This raising of the tines may also be performed from the seat with the
aid of pedal P Figure 1 connected with the tine frame by usual means.
Figure 8 represents a tine socket 6 made in halves united by the shank of the tine
made of I section engaging by its flanges with the two parts of the socket which are
correspondingly shaped as shewn at a and to which the tine is secured by a bolt 4.
These divided sockets enable renewals to be easily effected without risk of breakage
which is liable to happen in dismounting the machine for the purpose, as heretofore
necessary, such breakage often resulting from the bending of the tine carrying rod
which has become rusted from exposure.
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 herein described horse rake constructed to operate as herein described and
provided with the improvements hereinafter specified.
2. In the herein described horse rake the combination, with the ratchet and pawl
mechanism for throwing up the tines, of the pawl disengaging device consisting of
