I JEAN ANNE CARLES of Pins-Verts Léguevin in the department of Haute-
Garonne in the Rupublic of France do hereby declare the nature of
invention for IMPROVEMENTS IN RAKES FOR AGRICULTURAL PURPOSES to be as
follows:-
This invention has for object the construction of an agricultural rake called a
hand rake drawn by cords system Carlès, for purpose of raking herbs, hay, and
such like. This rake is of simple construction and requires but light force for
operating it.
This improved rake is composed of four principal parts:-:
(1) of a series of parallel teeth or points.
(2) of a table with two sides.
(3) of an axle with two wheels.
(4) of an arrangement for driving and guiding.
In the drawings Fig. 4 shows in detail a tooth of the rake.
:
The extremity of the tooth is slightly curved upwards and the form of the tooth'
somewhat resembles the letter S as shown by the drawing and has thereon for a
part of its length a strengthening web and its upper extremity is furnished with
two heels r, r. The heel is pierced by the hole o into which is passed a bar
which holds all the teeth together. These are further sustained by a flat bar B in
which is provided two nitches one on the side b for purpose of allowing the heel
to pass and another on the side b¹ where the heel 1 passes. In consequence of this
arrangement the teeth are movable in a vertical sense so as to allow of their being
raised or lifted when they meet an obstacle of the ground. The obstacle being
passed the tooth is brought again to its original position (by its own weight and
the pressure of a spring p screwed at one of its extremities to the bar Band
engaging with the other end in a notch furnished on the heel r. The teeth are
formed of triangular shape (as shown in the drawings). The two outer teeth D are
not movable but screwed on the plate or bar B. These carry on their outer sides
a ledge upon which are fixed the sheets S (which will be further described) forming
the sides of the rake.
The table of the rake is formed of very thin boards supported by an iron frame.
The form of this frame is shown in the drawings Figs. 1 and 2 and the middle
portion of the sides are made higher so as to be above the height of the wheels
which according to this arrangement roll on the soft ground already raked and the

page_text: higher portions of the sides will prevent any of the collected material from
entangling with or coming between the spokes of the wheels.
The iron frame on which rests the wooden table is composed of four longitudinal
pieces and of two transverse pieces held together by screws and nuts. Of the four
longitudinal pieces the two outside ones C are of angle iron and are bent outwards
from about the point where the wheels work..
The two middle pieces R are straight and each terminates in a handle of wood
or iron R¹; they may be of T or angle iron. The two transverse pieces are of flat
iron one of which is the band B already mentioned, the other is denoted in the
drawing by the letter H. The sheets forming the vertical sides S of the table
have the form shown by the drawings and are fixed to the vertical wings or sides
of the angle irons C, said sheets S are in addition at their parts towards the rake
bolted on to a cast piece T and on the vertical sides or flange of the end fixed
teeth D.
This part of the sheet S is bent so as to form an outward curving surface the
extremity whereof is lost in the point of the tooth D (Fig. 2) and in this manner
the sheets S will not form an obstacle to the material collected by the rake.
The axle E is bent in saddle form with side extending trunnions as shown in
Fig. 3, and the connection between it, and the table is effected by the piece I,
fixed on the transverse bar H. The piece I, saddles the axle, and a strong stud or
bolt is employed passing through the hole K, passing through the wings of the
piece I, and the axle E. In this way the table may balance itself in the vertical
sense by rocking upon the bolt passing through the holes K, which will allow of
the rake following the undulations of the ground.
The piece I, will not of itself be sufficient to resist the lateral movement of the
table, and there is added two saddle pieces F, one on each side of the table spanning
the axle, and fixed on the edges of the angle bars C. These two pieces F will
prevent the lateral movement of the table without preventing its rocking or
vertical sideway motion.
The system of driving or drawing is very simple. The cast piece T, of the side
frames, carry on their outsides two webs t, and t¹ parallel to each other, and con-
nected together by the plate q, screwed on their ends, and to give further resistance
to the web t¹, it is secured at its lower end to the cast piece T, by a horizontal
web. The two webs t and t¹ are each furnished with a hole n, and n into which
is passed at each side of the machine a shank or arm A, held at its extremity by a
strong pin. The holes n¹, are of oblong form so that the arms A, may be able to
move freely in a horizontal sense. The two arms A, are connected together by à
whipple tree h, to which may be harnessed the horse or horses which will draw
the rake.
Finally to enable the operator to transport the rake from one side to another
without running the risk of spoiling the teeth, a small wheel L (Fig. 1) is mounted
in the centre of the bar B, the axle of which said wheel L will turn in two holes 2,
of the extremities of the two iron plates m, which connect together above, and to
the bar B. by means of pins, whereby the wheel L, may be mounted and dis-
mounted as required.

of the tooth somewhat resembles the letter S as shown by the drawing and has
thereon for a part of its length a strengthening web and its upper extremity is
furnished with two heels 7, r. The heel ¹, is pierced by the hole o, into which
is passed a bar which holds all the teeth together These are further sustained
by a flat bar. B in which is provided two notches one on the side b, for purpose of
allowing the heel 7, to pass and another on the side b', where the heel ¹ passes.
.
In consequence of this arrangement the teeth are movable in a vertical sense so
as to allow of their being raised or lifted when they meet an obstacle of the
ground. The obstacle being passed the tooth is brought again to its original
position (by its own weight and the pressure of a spring p, screwed at one of its
extremities to the bar B and engaging with the other end in a notch furnished on
the heel r. The teeth are formed of triangular shape (as shown in the drawings)
The two outer teeth D are not movable but screwed on the plate or bar B,. These
carry on their outer sides a ledge upon which are fixed the sheets S, (which will
be further described) forming the sides of the rake.
The table of the rake is formed of very thin boards supported by an iron frame.
The form of this frame is shown in the drawings, Figs. 1 and 2, and the middle
portion of the sides are made higher so as to be above the height of the wheels
which according to this arrangement roll on the soft ground already raked and the
higher portions of the sides will prevent any of the collected material from
entangling with or coming between the spokes of the wheels.
The iron frame on which rests the wooden table is composed of four longitudinal
pieces and of two transverse pieces held together by screws and nuts. Of the four
longitudinal pieces the two outside ones C, are of angle iron and are bent outwards
from about the point where the wheels work.
The two middle pieces R are straight and each terminates in a handle of wood
or iron R'; they may be of T or angle iron. The two transverse pieces are of flat
iron one of which is the band B already mentioned, the other is denoted in the
drawing by the letter H. The sheets forming the vertical sides S of the table have

page_text: the form shown by the drawings and are fixed to the vertical wings or sides of the
angle iron C, said sheets S are in addition at their parts towards the rake bolted
on to a cast piece T and on the vertical sides or flange of the end fixed teeth D.
This part of the sheet S is bent. so as to form an outward curving surface the
extremity whereof is lost in the point of the tooth D, (Fig. 2) and in this manner
the sheets S will not form an obstacle to the material collected by the rake.
The axle E is bent in saddle form with side extending. trunnions as shown in
Fig. 3, and the connection between it and the table is effected by the piece I, fixed
on the transverse bar H. The piece I, saddles the axle and a strong stud or bolt is
employed passing the the hole R.passing through the wings of the piece I, and
the axle E. In this way the table may balance itself in the vertical sense by
rocking upon the bolt passing through the holes K, which will allow of the rake
following the undulations of the ground.
The piece I, will not of itself be sufficient to resist the lateral movement of the
table and there is added two saddle pieces F, one on each side of the table spanning
the axle, and fixed on the edges of the angle bars C, These two pieces F will
prevent the lateral movement of the table without preventing its rocking or vertical
sideway motion.
The system of driving or drawing is very simple. The cast piece T,. of the side,
frames, carry on their outsides two webs t, and t¹, parallel to each other, and
connected together by the plate q screwed on their ends, and to give further
resistance to the web t', it is secured at its lower end to the cast piece T by a
horizontal web. The two webs t and t¹ are each furnished with a hole n and n¹
into which is passed at each side of the machine a shank or arm A, held at its
extremity by a strong pin. The holes n¹, are of oblong form so that the arms A
may be able to move freely in a horizontal sense. The two arms A are connected
together by a whipple tree 1, to which may be harnessed the horse or horses which
will draw the rake.
Finally to enable the operator to transport the rake from one side to another
without running the risk of spoiling the teeth, a small wheel L Fig. 1 is mounted
in the centre of the bar B, the axle of which said wheel L will turn in two
holes Z, of the extremities of the two iron plates m, which connect together above
and to the har B, by means of pins whereby the wheel L, may be mounted and
dismounted as required.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
Firstly. The special construction of the movable S formed teeth mounted for
vertical displacement for rising over obstacles, with the spring p. acting on the
part r, of the tooth serving in addition to the weight of the tooth to return the
tooth to its original position after being raised as herein set forth.
Secondly. The table of the rake, serving to receive the raked material, con-
structed so as to protect by the enlarged rear portion the wheels of the rake as
set forth.
Thirdly. The arrangement of the table in relation to the axle to allow of the
movement of the table according to irregularities of the ground as set forth.
