IMPROVEMENTS
This Invention has for its object improvements in harvesting machinery.
I construct mowing and reaping machines as follows:-the draft pole is hinged
by a bracket and bolt to the frame, to the same bolt is binged a bracket for
carrying the steerage pole and castor wheel it also carries the lifting and regulating
levers. The arrangement is such that the castor wheel can run closer to the uncut
crop when mowing and farther from the uncut crop when reaping. The two
brackets may be connected when it is desired to dispense with the steerage pole
and castor wheel.
Where the sheaf is delivered automatically in the rear of the machine I employ
an improved feathering rake with teeth descending nearly vertically in the crop
maintaining that position until they have delivered the sheaf and then being
allowed to take a backward motion to prevent scattering the sheaf. The feathering
motion is given by a fixed cam on the reel bearing, acting on a short lever, hinged
at one end on the reel socket, the other end is connected to a bell crank on the
rake. About the middle of this short lever is mounted a roller which runs on the
fixed cam being held on it by a spring.
Where the sheaf is delivered automatically at the side of the machine I employ
for enabling the driver to regulate the size of the sheaf and to suspend the delivery
of the sheaves when turning the corners of the field, mechanism consisting of a
disc driven from the rake shaft, but at a slower rate of speed. For example, when
the machine is fitted with 4 rakes, I prefer to drive the disc at the rate of one
revolution to three of the rake shaft, on this disc are formed five concentric series
of projections for tripping the latch which is carried on a bar pivotted at one end,
and free to move over these five series of projections. By this means the driver is

page_text: enabled to bring into raking action every 2nd 3rd 4th 6th or 12th rakes. To suspend
the rake action the disc is held in working position by a spring operated on by a
lever placed conveniently for the drivers foot, by pressing on this lever he with-
draws the disc from contact with the tripping latch, then all the rakes pass over
the platform as dummies.
Where the sheaf is delivered and bound I make a better separation betwixt the
bound sheaf and the unbound corn by mounting a supplementary spindle parallel
with the needle spindle and a few inches beyond the range of the needle and
supplementary blind needles.
This spindle is armed with prongs which enter the crop almost simultaneously
with the needle, and having a backward motion they cause the distance to be
increased between the unbound crop and the sheaf in progress of binding, thus
causing a better separation. This motion is obtained by partially rotating the
supplementary spindle. This partial rotation is obtained by a cam formed on the
end of the supplementary spindle, acted on by a prolongation of the arm that
actuates the needle spindle. Another method of obtaining a better separation is
by endless convoyers on pullies fitted on the packer spindle, the other end of the
endless conveyers being carried by independent pullies. These endless conveyers
carry the crop to the packers, and when sufficient ha sbeen packed to form a sheaf
and to start the binding mechanism, the grain is shut off from the endless conveyers
and that which is on the conveyers is rapidly carried within range of the needle,
thus causing a better separation.
To reduce the width-of-self-binding-reapers Imount the geared travelling wheel in
the rear of the platform, the front part of the platform being supported by a castor
wheel (about which the draft pole is pivotted) and carried by a wheel at the side
next the standing corn. This wheel is mounted on a hinged frame and is con-
nected by chains and levels to the pivotted draft-polo, so that the action in turning
the horses at the corner of the field causes the corn side wheel to assume a position
in which it passes more readily over the ground, causing the machine to turn easier.
In this machine the crop is brought to the binding table by one series of ondless
conveyers kept down by small runners when it is desired to bind the sheaf at a
low level, and by two or three series when the sheaf is bound at a higher level.
The first series is horizontal and the second and third series set at an angle thereto.
One series may be driven from the packer shaft. They are kept apart and tight
by an extension pulley. To relieve from strain the string on which the bound
sheaf is being delivered I form a projection on the cam to sustain the pressure of
the spring that closes the knotter jaw.
To gather and bind the crop which has been cut and laid on the ground I employ
a frame mounted on travelling wheels armed with prongs which run under and
raise the crop-then by one or two series of endless conveyers I cause it to be
carried to the binding table, one of these series of conveyers may be driven
from the packer shaft.

IN HARVESTING MACHINERY
"
The first part of this invention relates to mowing and reaping machines, the
draft pole is hinged by a bracket and bolt to the frame, to the same bolt is hinged
a bracket for carrying the steerage pole and castor wheel, it also carries the lifting
and regulating levers and is so arranged that the castor wheel can run closer to the
uncut crop when mowing and farther from the uncut crop when reaping, and the
two brackets may be connected when it is desired to dispense with the steerage
pole and castor wheel.
Figure 1 is a side elevation and Figure 2 a plan of part of a reaping and mowing
machine shewing the arrangement above described. a. is the pole hinged by a
bracket b. and bolt c to the frame. d. is the second bracket also hinged to the
bolt c, and carrying the pole e. to which the castor wheelf is secured. The pole e
is pivotted to the bracket dat e-it can be locked to the bracket by a bolt g
passed through a hole formed through it and through a hole in the bracket or this
bolt can be taken out and the pole be turned into the position shewn by dotted
lines and then again be similarly locked by the bolt being then passed through
another hole in the bracket. h is the cutter bar and h¹ the crank for driving the
knife. The cutter bar h is connected to the frame as is commonly the case by a
link which is jointed to the frame at j' and to the bar at The link is con-
nected by a rod to the pin or axis of the whipple tree which can slide to and fro a
distance lengthwise of the pole. is a stay passing from the lower part of the
link to the frame. . is the lifting lever carried at by the bracket d.
m is the
regulating lever also carried at m¹ by the same bracket-its lower end acts on or
is linked to a lug that stands out from the frame-As above stated the brackets b
and d inay if desired be connected when reaping and when it may be desired to
dispense with the steerage pole and castor wheel. nn are the main wheels upon
the axle of which the frame is hung.
The second part of this invention relates to that class of reaper in which the
sheaf is delivered automatically in the rear of the machine and consists of an
improved feathering rake, the teeth descending nearly vertically in the crop,
maintaining that position until they have delivered the sheaf, they are then
allowed to take a backward motion so as to prevent them scattering the sheaf.
The feathering motion is given by a fixed cam on the reel bearing, acting on a
short lever, hinged at one end on the reel socket, the other end is connected to a
bell crank on the rake, about the middle of this short lever is mounted a roller
which runs on the fixed cam being held on it by a spring.
This improvement is shewn at Figure 3. A is a horizontal rake axis. B the
rake and beater arms-One of the arms has jointed to its extremity a set of
rake teeth C. From the axis of this set of teeth extends a short arm D-this is
coupled by a connecting rod E to a lever F. The opposite end of this lever is
hinged at F to the reel socket G. The lever F at a point intermediate of its
length carries a roller F, which by a spring H acting on the lever is held against
the side of a cam I fixed on the bearing of the reel axis J is the finger bar of the
machine.
The third part of this invention relates to that class of reaper wherein the sheaf

page_text: such a position that the projections upon its face may act upon the tail end of the
latch The disc can however be depressed by the forked end of a lever I which
embraces its axis at the part marked I' in Fig: 5.
The lever I turns on a centre at I³ its other arm is coupled by a connecting
rod 13 to a treadle lever I', which can be acted upon by the foot of the driver-
When the driver depresses the treadle the disc is thereby lowered so that the
projections upon it no longer act upon the tail end of the latch all the rakes then
pass above the platform and do not deliver any out crop from it.
The fourth part of this Invention relates to that class of reaper in which the
sheaf is delivered and bound and consists in making a better separation betwixt
the bound sheaf and the unbound corn and is accomplished by fitting endless
conveyers on pulleys fitted on the packer spindle the other end of the endless
conveyers being carried by independent pulleys these endless conveyers carry the
crop to the packers and when sufficient has been packed to form a sheaf and to
start the binding mechanism the grain is shut off from the endless conveyers and
that which is on the conveyers is rapidly carried within range of the needle thus
causing a better separation.
This arrangement is shewn at Fig: 7-A. is a sloping platform down which the
cut crop to be bound is conveyed by teeth standing up from endless bands B
these are carried by pulleys B'. the lower ones of which are on the packer spindle
and these therefore are driven continuously-The packers and the stop fingers up to
and against which the packers feed the cut crop and which are situated at the
lower end of the platform A are not shewn in the drawing as their action is well
understood.
When the crop fed up to the stop fingers bears with sufficient pressure against
them to press them back the movement of the fingers sets into action gear which
causes the wheel C to make one revolution-This by the links C' causes the
needle E to rise and carry a cord around the bundle and to deliver the cord carried
by its end to a knotter by means of which the ends of the cord around the sheaf
are knotted together and the sheaf thereby bound as is well understood On the
wheel C is a cam path C2 against this cam path rests a roller D' on a lever D it
is pressed against it by the action of a spring D-The extremity of the lever D is
coupled by a rod D³ to a short arm on an axis E-on this axis are teeth E'-So
Boon as the wheel C commences to revolve the end of the cam path C2 is carried
past the roller D'-the lever D is at once turned a distance by the spring D' which
acts upon it and the teeth E¹ are thereby turned into the position shown by the
dotted lines in the drawing-at the same time any crop on the platform is rapidly
carried along it so as to bring it within range of the needle E the needle E does
not at once commence to rise as the link C. is slotted at its end as shewn where it
is jointed to an arm on the axis of the needle-03 is a cam on the axis of the
wheel C for acting upon the stop fingers or as they are commonly called the
starting fingers to depress them when the sheaf has been bound and is ready to be
delivered.
The fifth part of this Invention is as follows-In order to reduce the width of
self binding reapers I mount the geared travelling wheel in the rear of the
platform the front part of the platform being supported by a castor wheel (about
which the draft pole is pivoted) and carried by a wheel at the side next the
standing corn, the wheel is mounted on a hinged frame so that the action in turning
the horses at the corner of the field causes the corn side wheel to assume a position
in which it passes more readily over the ground causing the machine to turn
easier-This arrangement is shewn in plan view at Fig 8 and in side elevation at
Fig 9-a front elevation of the wheel which is at the side next the standing
corn is shewn at Fig 10 and in side elevation of the same wheel at Fig 11-In
these figures A is the frame of the implement B the travelling and driving wheel
supporting its rear end C the castor wheel supporting its front end D the draft
pole carried by the vertical axis of the castor wheel E is the wheel by which the

page_text: side of the platform next to the standing crop is supported-It is carried by an
arm E which can turn freely around a fixed vertical rod E2. A collar E³ fixed by
a bolt to the rod E' rests on the top of the arm E¹. where it embraces the rod E* and
keeps this end of the platform at the elevation required-F is another fixed rod
which passes down through a slot in the arm E' and limits the extent to which it can
turn around the rod E-When the machine is being drawn forwards in a straight
line the wheel assumes the position shewn by full lines in Fig 8-When the machine
is being turned at the corner of the field the wheel turns into the position shewn by
dotted lines in that figure-In order to prevent the wheel from turning into this
position whenever the machine is being backed a treadle lever G within reach of the
driver is provided, this treadle is depressed by the drivers foot a link G passing
from an arm on the axis of the treadle to the arm E' holds the wheel in the
position shewn by full lines-H H are endless bands by which the cut crop falling
on to the platform in rear of the finger bar I is conveyed to the side of the
machine in front of the main driving wheel and is there delivered to binding
mechanism which may be of any ordinary description or the crop may be delivered
on to the ground in a continuous swathe-In this way the cut crop is delivered to
the binding mechanism without being conveyed over the top of the main driving
wheel as is now for the most part usual.
In reaping machines in which the sheaves are bound by a cord passed around
them and knotted in order to relieve the string from the strain on it when the
bound sheaf is being delivered I form a projection on the cam to relieve the
pressure of the spring that closes the knotter jaw just when the string has to be
drawn from it-This arrangement is illustrated at Figs 12 13 and 14-Fig 12
-is-an-underside-view-of-the-knotter-and-its-actuating mechanism-Fig 13 a side
elevation of the same and Fig 14 a cross section of the knotter-The knotter is
of ordinary well known construction its moveable jaw A is held against the fixed
jaw B by the action upon it of a spring C to cause it to grasp and hold the string
delivered to it At the time that the string is to be placed between its jaws the
moveable jaw is held open by the action upon its tail end of a cam piece (not
shown) on the disc D which disc is as usual made to make one complete turn each time
that a sheaf is being bound-When the string has been placed between the jaws of
the knotter the knotter jaws are allowed to close and the knotter is revolved by a
certain number of teeth on the face of the disc then gearing with a toothed wheel
on the knotter axis and the knot is so formed as is well understood When the
sheaf has been bound and is ready to be delivered it is usual for the ends of the
string which binds up the sheaf to be dragged out from between the jaws of the
knotter instead of this I relieve the string at this time from the pressure of
the jaws by causing a cam incline E on the edge of the disc D to move back
the spring C away from the moveable jaw so relieving the string from the nip
of the jaws
Having thus described the nature of my invention and the manner of performing
the same I would have it understood that I claim
