We, THOMAS RANDOLL CATTELL, of Forde Hall, Wootton Wawen, Warwickshire,
Farmer, and ALFRED HENRY SUMMERS, of Tanworth, Warwickshire, Millwright, do
hereby declare the nature of this invention to be as follows:-
Our Invention consists in the new or improved combined mowing and tedding
machine hereinafter described by means of which a swath of grass can be tedded
whilst another swath is being mown, thus dispensing with the use of two separate
machines for these purposes, as heretofore ordinarily employed, and considerably
reducing the cost per acre of mowing and tedding.
In carrying out our Invention we arrange a revolving tedder at the back of a
mowing machine so that it teds the swath immediately preceeding that which is being
mown, as follows:-We take a rotary tedder of ordinary form consisting of prongs
mounted on an axle which is carried by bearings at the end of a light forked frame. The
said frame is supported from the ground at each side by a wheel on which the tedder
runs and which are capable of adjustment vertically so as to allow of any required varia-
tion in the height of the tedder from the ground. The said forked frame is so connected
to the back of the frame of the mowing inachine part that it can swivel sideways when
running round a curve and be tilted upwards or downwards by the attendant when
required to raise or lower the tedder. The tedder may either receive rotary motion
from one or both of its said side wheels by means of suitable gearing as now employed
for such machines, or it may be driven from one of the main side wheels of the
mowing machine by any suitable arrangement of mechanism such for instance as the
following: Near the back of the mowing machine and supported in suitable bearings
on the mowing machine frame is a horizontal shaft parallel to the main axle and
receiving motion from one of the side wheels by means of spur gearing. On this
shaft and preferably on the longitudinal centre line of the machine is a spheroidal
spur wheel gearing into which is a similar spur wheel fixed on a second shaft near to
the former and parallel with the axis of the tedder. The said second shaft carries a
spur wheel having external and internal teeth and gearing with the internal teeth is a
pinion free to turn in bearings carried by a plate which can be moved up and down

page_text: in suitable guides by a hand lever. Gearing with the external teeth is another pinion
also turning in bearings carried by the said plate. The said spur pinions are arranged
one above the other and so situated relative to each other that they are never both in
gear with their respective spur wheels at the same time. Fixed to each of the said
spur pinions is a chain wheel and on the tedder axle is another chain wheel the centres
of the three chain wheels foruting together the angles of a triangle. A drive-
chain passes around the three chain wheels. By means of the said hand lever the said
plate can be moved up so as to bring the pinion in gear with the internal toothed
wheel and run the tedder in one direction or by the same means the plate can be
lowered and the other spur pinion brought into gear with the external teeth thereby
causing the tedder to revolve in the opposite direction. The said first shaft revolves
in bearings formed with a plate on which is a horizontal spur segment of the same
radius as the spheroidal spur wheel and gearing with this spur seginent is another
similar spur segment with which the end bearings of the second shaft are formed
which is concentric with the spheroidal spur pinion on the second shaft. In front of
this second spur segment is a projecting arm to which the said forked frame is
connected and at the side is another projecting arm which carries the outer bearing of
the second shaft. A vertical pin projects below the second spur segment and fits in a
curved slot in a projecting piece formed with the first spur segment so as to keep the
segments in gear. The said spur segments and the pin working in the curved slot
maintains the said spheroidal spur wheels always properly in gear when the tedder is
swivelled to either side and the tedder and frame can be moved up or down on the
first shaft as a centre; for this purpose we provide a horizontal shaft under the forked
frame and carried by bearings from the mowing machine fraine on which shaft are
two cams, one under each side of the frame. On the said shaft is a lever connected
by suitable links to a hand lever in front of the machine by which the cams can be
partly revolved to raise or lower the tedder frame or a vertical spur quadrant may be
formed with the casing which carries the first spur segment into which gears a small
spur pinion capable of being turned by a hand lever.
It will be evident that other arrangements of mechanism for conveying rotary
motion from one or both of the side driving wheels of the mowing machine part to the
tedder and which will gear and drive when the tedder is swivelled sideways or moved
up and down can be employed such for instance as an arrangement of bevil wheels
and pinions the arrangement described being intended only by way of illustration and
not abridgment of the invention.

page_text: A New or Improved Combined Mowing and Tedding Machine.
We, THOMAS RANDOLL CATTELL, of Forde Hall, Wootten Wawen, Warwickshire,
Farmer, and ALFRED HENRY SUMMERS, of Tanworth, Warwickshire, Millwright,
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 :-
Our invention consists in the new or improved combined mowing and tedding
machine hereinafter described by means of which a swath of grass can be tedded
whilst another swath is being mown, thus dispensing with the use of two separate
machines for these purposes as heretofore ordinarily employed and considerably
reducing the cost por acre of mowing and tedding.
In carrying out our invention we arrange a revolving tedder at the back of a
mowing machine so that it teds the swath immediately preceeding that which is
being mown, as follows:-We take a rotary tedder of ordinary form consisting of
prongs mounted on an axle which is carried by bearings at the end of a light forked
frame. The said frame is supported from the ground at each side by a wheel on
which the tedder runs and which are capable of adjustment vertically so as to allow
of any required variation in the height of the tedder from the ground. The said
forked frame is so connected to the back of the frame of the mowing machine
part that it can swivel sideways when running round a curve and move up and
down to accommodate it to any uneven surface of the ground. The tedder may either
receive rotary motion from one or both of its said side wheels by means of suitable
gearing as now employed for such machines, or it may be driven from one or both
of the main side wheels of the mowing machine by any suitable arrangement of
mechanism.
On the accompanying drawings Fig. 1 is a general plan of a mowing and tedding
machine combined together according to our invention the tedder being driven in
the ordinary manner from one of its side wheels; Fig. 2 is a plan and Fig. 3 an
elevation on a larger scale of part of a modified form of our combined mowing and
tedding machine the tedder being driven by bevel gearing from the mowing machine,
and Figs. 3*, 3**, 3***, 3**** represent details of the same; Fig. 4 is a plan,
Fig. 5 an elevation and Fig. 6 shews details of part of a combined mowing and
edding machine in which the tedder is driven from the mower by a wire rope or
chain, and Fig. 7 represents a further modification of our invention.
The same letters of reference indicate similar parts in all the Figures.
Referring firstly to Fig. 1, A is a mowing machine of which a is the cutter bar,
a², a² are the side wheels, and bis the mowing machine frame. The mowing machine
is represented as moving towards the right hand and cutting the standing grass B.
C is a rotary tedder of ordinary form consisting of prongs c mounted on an axle d
which is carried by bearings at the end e¹ of a light forked frame E. This frame E
is supported from the ground at each side by a wheel ƒ³, ƒ" on which the tedder
runs and from which the axle d receives rotary motion, these wheels being capable of

page_text: now
adjustment vertically so as to allow of any required variation in the height of the tedder
from the ground. The means by which the tedder axle d is driven from the side
wheels ff, and the arrangement of parts for the adjustment of the wheels f¹ƒ³
forms no part of this invention and may be similar to the means
ordinarily einployed for other tedding machines. The forked frame E has an arm e
projecting forwards towards the mowing machine and at the outer end e* of this arm
is an universal joint which may be of any ordinary form (such for instance as that
known as Hooke's Universal Joint) and by which the end e of the arm is jointed and
connected to the mowing machine frame. This universal joint allows of the tedder
swivelling sideways in either direction (as shewn by the dotted lines) when running
round a curve and it also allows of the tedder rising or falling or of one wheel (say f¹)
being higher or lower than the other wheel so as to run over uneven ground with-
out straining the connecting arm e². In the combined mowing and tedding machine
represented by Fig. 1 the axle d'carrying the tedder prongs receives rotary motion
from one or both of the side wheels", as above described but, as this necessitates
the wheels and the tedder generally being made heavy so as to prevent the
wheels slipping when the grass is damp, we prefer to obtain the rotary motion
of the tedder axle d from some revolving part of the mowing machine (thus enabling
us to make the tedder part very light) which can be effected in various ways one of
which, by way of example, we will now describe by referring more particularly to
Figs. 2 and 3. We provide a short vertical shaft g carried by a bracket h fixed to
the framework of the mower. This shaft g receives rotary motion (by means of the
bevel wheels g², ³) from a horizontal shaft i forming part of the mowing machine for
operating the cutter bar a and driven from one or both of its side wheels a². At the
upper end of the vertical shaft g is an universal joint of connecting the shaft g with
an upper shaft 9. Rotary motion is transmitted from the upper shaft g' to a hori-
zontal shaft by mitre wheels j', and the motion of the shaft k is transmitted to
another horizontal shaft running in bearings 1, 13, 1 on the frame E by means of
three mitre wheels m¹, m², m³. The wheel m¹ is fixed to the shaft k, and the
wheels m³, m³ run loose on the shaft l, a clutch m¹ being provided which can be
moved to and fro to be out of gear with both of the wheels m³, m³, or to engage with
either of them so as to either stop or reverse the motion of the shaft l. Motion is
transmitted from the shaft. I to the tedder spindle d by a chain q passing round a
chain wheel on the shaft land round a similar wheel o on the end of the tedder
spindle d. The tedder drum e' carrying the tines c is preferably connected to the
tedder spindled by an ordinary cone friction clutch c which allows the spindle d to
slip round when the tines meet with an obstruction and prevents their breaking. A
guard is provided for preventing the grass becoming entangled in the chain q. By
means of the shafts and gearing above described rotary motion from the mowing
machine wheels a' is transmitted to the tedder axle d and the tedder axle can be caused
to revolve in either direction or to cease revolving when required. The shaft & runs
in a tubular sleeve which at one end is fixed to the bracket L having the bearings 1³, 13
above mentioned and at the other end fits in a bearing r in the bracket R, hereinafter
described, in which it can turn. By this means the one side of the frame E can rise
higher than the other, turning round the shaft as a centre. The frame E and
driving gear can swivel sideways as shewn by dotted lines in Fig. 2 by turning round
the vertical shaft g as a centre, or move up and down round the universal joint g¹
by which rotary motion is transmitted from the shaft g to the shaft g. The bracket R
(shewn separately by Fig. 3*) in which are the bearings for the shafts & and g' is
connected to the bracket S (shewn separately by Fig. 3**) in which the shaft g
revolves and which turns freely in the bracket h, by the cross-piece T which con-
stitutes two axes t', t, at right angles to each other coinciding with the cross axes of
the universal joint g. The ends of the axis t¹ take into bearings in the bracket R,
and the ends of the axis t take into bearings in the bracket S thus allowing of the
bracket R twisting sideways or up and down to accomodate itself to the motion of
the frame E.
In-the modification illustrated by Figs. 4, 5 and.6 the shaft.. is driven by a wire.

page_text: u2
This
rope instead of by gearing as in the modification shewn by Figs. 2, 3, 3*, 3**, 3***,
3****. A short horizontal shaft is carried above the shaft by brackets U¹, U'
in which it revolves; the shaft receiving motion from the shaft i by spur wheels u',
one of which is provided with an ordinary sliding clutch u for stopping and starting
the shaft when required. The shaft carries a rope pulley V₁ and a similar
pulley V2 is fixed to the shaft and around these pulleys passes the wire rope v.
rope v is so arranged as hereinafter described that it will drive the pulley V² either
when the tedder and mowing machine are in a line as shewn by Figs. 4 and 5 or
when the tedder has moved to either side as in rounding a curve (see dotted lines
Fig. 4) or when it has moved up or down (see dotted lines Fig. 5) or swivelled side-
ways; and this is accomplished as follows:-Free to turn in a vertical plane round
the shaft is a forked bracket W to the back of which is hinged a tail piece w' which
is turned at its outer end 10 and fits in a hole z in the bracket X in which are the
bearings, for the shaft l. The rope passes between two pairs of guide
pulleys w³, which are free to revolve on projecting pins on the bracket W and
which maintain the rope always in the plane of the pulley V.
These guide
pulleys . to are in a line with the hinge pin around which the tail piece c¹ turns
when the machine is rounding a curve (see dotted lines Fig. 4) thus_maintaining the
rope u tight and in the plane of tho pulley V. The forked frame E, the revolving
tedder, and its driving gear can all vibrate from the shaft as a centre as will be
readily understood by examining Fig. 5. By the outer end of the tail piece fitting
loosely in the hole, the bracket X and shaft can swivel up or down round the
outer end to as a centre when one of the wheels (say f³) of the tedder is higher
than the other wheel in running over uneven ground.
In the modification of this invention illustrated in plan by Fig. 7 the tedder is
arranged to revolve at a slight angle with the axis of the wheels a² of the mowing
machine when the machine is running straight, instead of being parallel therewith as
in the modifications illustrated by the preceeding Figures. The object of this arrange-
ment is to enable the tedder to throw the cut grass well away from that which is
standing. The shaft is driven by the bevel wheels y, y from the shaft k and the
latter receives motion from the shaft i of the mowing machine by the arrangement of
gearing hereinbefore described and illustrated by Figs. 2, 3, 3*, 3**, 3***, 3****.
The axles of the wheels f¹, fare carried from the forked frame E and arranged to
be adjusted vertically similarly as above described with reference to the modifications
in which the tedder axle is parallel with the axles of the wheels a³.
We generally provide an ordinary hood Z around the front of the revolving tedder
to prevent the grass being thrown on to the mowing machine but this is not always
required.
In either of the arrangements represented on the drawings the tedder and its
driving gear can very readily be removed from the mowing machine so that the latter
can be used alone. This can be effected in the modification represented by Fig. 1 by
removing one of the ordinary joint pins in the universal joint at the outer end e³ of
the armne in the inodification represented by Figs. 1, 2, 3, 3*, 3**, 3***, 3**** by
removing the bolts ' which fix the bracket to the frame b; and in the modifica-
tion illustrated by Figs. 4, 5 and 6 by sliding the shaft endways in its bearings
when the bracket W and pulley V' and the parts connected to them will be free from
the mowing machine part.
It will be evident that other arrangements of mechanism for conveying rotary
motion from one or both of the side driving wheels of the mowing machine part to
the tedder and which will gear and drive when the tedder is swivelled sideways or
moved up and down can be employed without departing from the spirit of our
invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is:
1. The combination with a mowing machine. of a revolving tedder receiving

page_text: rotary motion from and running on side wheels behind the mowing machine, and
loosely connected to the mowing machine, and constructed and arranged to operate
substantially as hereinbefore described and illustrated by Fig. 1 of the accompanying
drawings.

and operating substantially as hereinbefore described and illustrated by Figs. 2, 3,
3*, **, 3*** 3**** of the accompanying drawings.
4. In a combined mowing and tedding machine in which the tedder runs behind
the mowing machine, the employment of gearing for connecting the tedder and
mowing machine together and for transmitting rotary motion to the tedder axle from

and operating substantially as herein before described and illustrated by Figs. 4, 5
and 6 of the accompanying drawings.
5. In a combined mowing and tedding machine in which the tedder runs behind
the mowing machine, arranging the tedder axle to revolve at an angle with the axle
of the mowing machine for the purpose and substantially as hereinbefore described
with reference to Fig. 7 of the accompanying drawings.
