Improvements in Horse Rakes.
I, JULIEN EMILE THOMÉ, of Nouzon, Ardennes, France, Ironfounder, do
hereby declare the nature of this invention to be as follows:-
My improvements in horse rakes relate more particularly to the mechanism for
throwing up and letting fall 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 sectional side elevation, and Figure 2 a plan, of the rake
with the tines in work;
Figure 3 shews a sectional side elevation with the times thrown up as when out
of work or travelling;
Figure 4 shews the mechanism for holding the pawls disengaged from the
ratchets to allow the tines to fall back into work, as shewn in Figure 1;
Figure 5 is a detail face view of the mechanism for holding the tines raised
when out of work;
Figures 6 and 7 are sectional side views of the same with the tines thrown up
and in the working position respectively.
The same letters of reference indicate the same parts in all the figures.
f
The tines a are mounted in a head frame e pivoted upon the axle d of wheels e
upon whose hubs are keyed ratchet-pinions with which engage pawls g pivoted to
the frame b. The pawls are held out of engagement with the ratchets, except
when the tines are to be thrown up, by fingers h mounted on the ends of a rock
shaft i operated by a treadle as hereinafter described which shaft is locked by a
bolt k engaging in a notch m in a segment j fast on the rock shaft i. A spring j
attached to segment j, together with the weight of fingers h, tends to withdraw the
fingers and allow the pawls g to fall on to the ratchets f. The spring is not
absolutely necessary as the weight of the segment and fingers is sufficient to rock
the shaft i. The bolt is pressed into the notch m by a spring and is jointed to
the rear end of the treadle l so that by pressing down the latter, the bolt k will be
disengaged from the notch m and the pawls g will be allowed to fall into gear with
the ratchets whereby the tine-carrying frame b will be rotated with the wheels and
the tines will be thrown up to the position shewn in Figure 3 for discharging the
hay collected. The tines are allowed to fall again by the fingers h being struck by
the levers v pivoted on the side frames of the machine, thereby rocking shaft i and
disengaging pawls g from ratchets f and relocking segment by the bolt k, said
lever being operated by a cam a keyed on axle d striking its tail end and so
raising the finger / and pawl y, as shewn in Figure 4, the mechanism being similar
at both sides of the machine.
The tines are held up for travelling by an arm 8 (Figures 5, 6, and 7,) fixed to
on the
the frame e engaging with a latch 7 carried by a hand lever 5 pivoted at
main frame within reach of the driver, the latch being free to oscillate only in the
direction of the arrow (Figure 7). When the tines are to be held up, the hand
lever 5 is moved sideways so as to bring the latch 7 into the path of arm 8 and the
treadle is then depressed so as to engage the pawls g with the ratchets, thus
throwing up the tines and engaging the arm 8 with latch 7.
Figure 8 shews a side view of a modification, in which the tine-raising mechanism
is operated from the rear of the rake by means of a hand lever 9 acting on the

relatively to the driver's seat.

COMITETE SPECIFICATION.
Improvements in Horse Rakes.
I, JULIEN EMILE THOME of Nouzon, Ardennes, France, Ironfounder, do
bereby 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 relate more particularly to the mechanism for
throwing up and letting fall the tines whereby a quick action of the machine is
obtained.
Reference is to be had to the drawings forming part of my Provisional Specifi-
cation wherein
Figure 1 represents a sectional side elevation, and Figure 2 a plan of the rake
with the tines in work.
Figure 3 shews a sectional side elevation with the tines thrown up as when out
of work or travelling.
Figure 4 shews the mechanism for holding the pawls out of engagement with the
ratchets to allow the tines to fall back into work, as shewn in Figure 1.
Figure 5 is a detail face view of the mechanism for holding the tines raised
when out of work.
Figures 6 and 7 are sectional side views of the same with the tines thrown up
and in the working position respectively.
The same letters of reference indicate the same parts in all the figures.
The tines a are mounted in a head frame b, c, pivoted upon the axle d of wheels e
upon whose hubs are keyed ratchet-pinions with which engage pawis g pivoted to
the frame. The pawls are held out of engagement with the ratchets, except
when the tines are to be thrown up, by fingers h mounted on the return ends of a
rock shaft i operated by a treadle as hereinafter described, which shaft is locked
by a bolt kon said treadle engaging in a notch m in a segment j fast on the rock
shaft i. A spring attached to segment j assisted by the weight of fingers h,
tends to withdraw the fingers and allow the pawls g to fall on to the ratchets f.
The spring is not absolutely necessary as the weight of the segment and fingers is
sufficient to rock the shaft i. The bolt k is pressed into the notch m by a spring
and is jointed to the rear end of the treadle so that on the driver pressing down
the latter when the tines are in work the bolt will be disengaged from the
notch m and the pawls g will be allowed to fall into gear with the ratchets whereby
the tine-carrying frame 6 will be rotated with the wheels and the tines will be
thrown up to the position shewn in Figure 3 for discharging the hay collected.
The tines are allowed to fall again by the fingers being struck by the levers v
(Figure 4) pivoted on the side frames of the machine, thereby rocking shaft i and
disengaging pawls g from ratchets f and relocking segment by the bolt k, said
lever being operated by a cam keyed on axle d striking its tail end and so
raising the finger h and pawl g, as shewn in Figure 4, the mechanism being similar
at both sides of the machine.
The tines are held up for travelling by an arm 8 (Figures 5, 6, and 7,) fixed to
the frame engaging with a latch 7 carried by a hand lever 5 pivoted at 6 on the
main frame within reach of the driver, the latch being free to oscillate only in the
direction of the arrow (Figure 7). When the tines are to be held up, the hand
lever 5 is moved sideways, so as to bring the latch 7 into the path of arm 8 and

page_text: the treadle is then depressed so as to engage the pawls g with the ratchets, thus
throwing up the tines and engaging the arm 8 with latch 7, so as to retain them in-
the raised position.
Figure 8 shews a side view of a modification in which the tine-raising mechanism
is operated from the rear of the rake by means of a hand lever 9 acting on the
treadle.
Figure 9 shews in front view, the positions of the hand lever 5 and treadle l
relatively to the driver's seat.
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--
1st. In a horse-rake, the combination of a ratchet wheel turning with the wheel,
a pawl g and finger h for supporting the pawl, a cam and lever v for disengaging
the pawl from the ratchet and allowing the tines to fall again, as described and
illustrated more particularly in Figure 4.
2nd. The combination, with the mechanism forming the subject of the preceding
claim, of the rock shaft i, segment j, locking bolt k, treadle l, and lever 9 (Figures 8
and 9) for holding the pawls out of gear and for unlocking bolt k and letting the
pawls fall into their ratchets for producing, by the motion of the wheels, the
throwing up of the tines until the pawls are disengaged by the lever v to let
the tines again fall into work, as described.
3rd. The arrangement for supporting the tines in the raised position for travelling,
consisting of the lever 5 and latch 7 and arm 8 engaging therewith, mounted on.
the rake head frame, as described, and illustrated in Figures 5, 6, and 7.
