THOMAS CHARLES SARGEANT The Limes Victoria Promenade Northamptou
Engineer do hereby declare the nature of this invention to be as follows :—
My invention relates to that type of harvester which binds & ejects the grain on
the opposite side of the main driving wheel to that on which it is cut, and consists
in an improved method of trussing the grain, conveying the grain over the main
driving wheel compressing and finally ejecting the bound bundle by which I get
an even distribution of weight on each side of the main driving wheel a complete
separation of the bound bundle from the unbound grain dispence with the
binder ejector and obtain a considerable reduction in the total, width, weight, &
number of working parts of the machine. The grain when cut falls in the usual
way into an endless conveyor which consists of an endless band running over rollers
at each end of the platform. At the delivery end of the endless conveyor I place
a drum the axis of which is parallel to that of the conveyor rollers. To this drum
are jointed a series of feathering hooks the tail end of which are carried by friction
rollers running upon cam tracks, the feathering of the said hooks being
determined by the varying inclination of the said tram tracks. These hooks
project into a channel or passage leading from the delivery end of the conveyor to
the trussing chamber which is located above the rotary drum and consists of a
series of irons curved towards the main driving wheel, at their upper extremity
forming a receptical or cradle which when packed with grain to the required
density operates a trip catch by which the knotting and binding mechanism is put
into action the needle bracket which is placed on the opposite side of the main
driving wheel to that on which the grain is cut, is arranged to swing or vibrate
upon the knotter spindle; when the cradle is filled with grain and the binding
mechanism is put into gear, the upper part of the needle bracket to which the
needle is jointed swings towards the cradle where the needle embraces the trussed
grain the bracket then swings back and the trussed grain being embraced by the
needle is carried from that side of the main driving wheel on which it is cut to the
opposite side on which it is bound & finally deposited. The function of the swinging
bracket being to convey the grain from one side of the main driving wheel to the
other. The compressor consists of an arm jointed to the upper part of the swinging
bracket and operated by a cam or segment formed on the boss of the needle arm.
The bound sheaf is ejected by the compression while in the act of compressing the
unbound sheaf.

Improvements in the Construction of Sheaf Binding Harvesters.
I, THOMAS CHARLES SARGEANT, of. The Limes Victoria Promenade,
Northampton, Engineer, 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 invention relates to that type of harvester which binds and ejects the grain
on the opposite side of the main driving wheel to that on which it is cut, and
consists in an improved method of trussing the grain, conveying the grain over the
main driving wheel, compressing and finally ejecting the bound bundle, by which I

get an even distribution of weight on each side of the main driving wheel, a
complete separation of the bound bundle from the unbound grain, dispense with the
bundle ejector and obtain a considerable reduction in the total width, weight, and
number of working parts of the machine. The grain when cut falls in the usual
way on to an endless conveyor, which consists of an endless band running over
rollers at each end of the platform. At the delivery end of the endless_conveyor
I place a drum the axis of which is parallel to that of the conveyor rollers. To
this drum are jointed a series of feathering hooks, the tail ends of which are carried
by friction rollers running upon cam tracks, the feathering of the said hooks being
determined by the varying inclinations of the said cam tracks. These hooks
project into a channel or passage leading from the delivery end of the conveyor to
the trussing chamber which is located above the rotary drum, and consists of a
series of irons curved towards the main driving wheel at their upper extremities
forming a receptacle or cradle which when packed with grain to the required
density operates a trip catch by which the knotting and binding mechanism is put
into action.
The needle bracket which is placed on the opposite side of the main driving
wheel to that on which the grain is cut is arranged to swing or vibrate upon the
knotter spindle. When the cradle is filled with grain and the binding mechanism
is put into gear, the upper part of the needle bracket to which the needle is jointed
swings towards the cradle where the needle embraces the trussed grain, the bracket
then swings back and the trussed grain being embraced by the needle is carried
from that side of the main driving wheel on which it is cut to the opposite side on
which it is bound and finally deposited.
The function of the swinging bracket being to carry the grain from one side of
the main driving wheel to the other.
The compressor consists of an arm jointed to the upper part of the swinging
bracket and operated by a cam or segment formed on the boss of the needle arm.
The bound sheaf is ejected by the compressor while in the act of compressing the
unbound sheaf.
And in order that my invention may be more clearly understood, I give the
following figures and description showing the apparatus employed.
Fig. 1. shows front elevation of the machine with a portion of the finger beam.
Fig. 2. shows back elevation partly in section.
Fig. 2 shows the drum and feathering hooks.
Fig. 3. shows side elevation also partly in section.
Fig. 4. is a plan of the machine.
Figs. 5 & 6 show the rotary telescopic drum and packing or lifting hooks.
Similar letters refer to the same parts in the different figures.
A is the main drive wheel which is carried in a frame B B in any of the usual
well known methods. To this frame is attached the finger bar C in which works
the cutting apparatus. Motion is given from the main driving wheel to the various
working parts of the machine by any suitable trains of gearing, and as I do not
confine myself to any particular method of driving these various parts I shall not
proceed to describe those shown in detail. D is the needle bracket which vibrates
upon the knotter shaft E on the opposite side of the driving wheel to that upon
which the cut corn first fails. F is the platform upon which runs the endless con-
veyor which may be of the usual constructions in this class of machiney, which
conveyor carries the grain to the rotating drum G which is fixed to and revolves
with the rotating shaft G'. The cut grain after it is conveyed towards the rotating
drum G by means of the endless platform conveyor, is elevated by means of the
hooks G2, G3, G2, G2, which may be either fixed on to the drum G as shown in
Figures 5 and 6, or may be made as a series of feathering hooks, as shown in
Fig. 24, the tail ends of which are carried by friction rollers gggg and run upon
a cam track W which determines the varying inclination of the hooks at different
portions of their revolution around the axis G¹. These series of hooks G² of
which I provide 2 or more on the rotating drum G raise the grain as it is brought

page_text: to them by means of the endless platform conveyor, and lifts it through the throat
or passage way H formed by means of a series of bars H', H', H, H', bent or
shaped as shown in Figure 2 etc., into the gavelling chamber H2. When sufficient
grain to form a bundle is collected in this gavelling chamber H2, it presses upon an
arm I which is pivotted on a shaft I', carried by the frame work of the machine,
and releases by means of the levers 12, 13 and connecting rod I, the trip 1° from
the usual trip stop on the train of gearing which drives the knotting mechanism,
and so allows the binding mechanism to come into action. At the same time the
cam wheel J is caused to rotate and lifts the vibrating arm I by means of a friction
roller or stud J¹ carried by the vibrating arm which runs in a suitable cam path,
and so allows the free egress of the cut grain lying in the gavelling chamber to be
lifted from this chamber by means of a lifting arm or arms K K. These arms K, K,
are connected by means of a crank pin L to the back of the crank wheel or cam
disc J, being at the top end connected by means of a pin L', to a short link K',
which link K, is hung upon a fixed shaft K2 carried by a portion of the frame
work of the machine. The cut grain being thus lifted by the arms K, K, is
raised on to or about the level of the binding table M. The vibrating needle
bracket D is then swung over towards the gavelling chamber on the opposite side
of the main driving wheel, as shown in the full lines in Fig. 2. The needle is then
caused to descend and embraces the trussed grain and carries it back over the
travelling wheel into the position shown in the dotted lines Fig. 2 on the opposite
or outside of the travelling wheel; as the usual well known train of gearing and
link motion can be used for giving the necessary movements to the vibrating needle
bracket D and needle I have shown a simple form but do not describe it, as this
gearing does not form any part of my Patent. When in the position shown in
dotted lines Fig. 2 the bundle is pressed between the needle N, compressor arm 0,
and top compressor arm X; this arm is pivotted at one end to the needle at X³,
and is connected at the other end to a link X', this link-being jointed to a lug X2
formed on the needle bracket. The compressed bundle of grain is then bound by
means of a cord or band in the usual manner. The needle N and compressor
arms & X are then opened and the bound bundle allowed to fall out, if however
the bundle does not of its own accord fall from the binding table M, the compressor
arm passes over the top of the bound bundle when the needle bracket makes
its next movement over towards the gavelling chamber, and then descending behind
the bundle in taking the following sheaf, pushes off or discharges the bound bundle
in its return movement. This compressor O vibrates upon a stud O, fixed to the
upper portion of the swinging needle bracket D and is operated by means of cams
or toothed segments as shown in Fig. 2, which are formed on the bosses of the
needle arin N and compressor arm 0, or the same motion can be obtained by means
of a connecting link Y attached to one end of a lever Y¹ which is pivotted to the
needle bracket and which lever is operated at the other end by means of a cam Y*
from the train of gearing which drives the knotting mechanism as shown in Fig. 1.
Upon the shaft Gare fixed two or more discs G³, G³, which carry the external
drum G and upon this external drum G are fixed the series of arms or feathering
hooks G2, G2, etc. G is a spur wheel which is driven from the main travelling
wheel by means of a suitable train of gearing, to this spur wheel G³ is attached a
short internal drum G' upon which the front end of the external telescopic drum G
slides. Motion is imparted from the internal drum G to the external one G by
means of a stud S fixed to the latter which slides in a slot S' in the internal drum G4.
The shaft G is carried at each end of the machine by suitable bearings in which it
slides, carrying with it the drum G and hooks, according to the relative position
in which it is desired to place the band upon the cut sheaf. Fig. 5 shows this
feeder extended on the internal drum G* to its extreme or outer limit, whilst Fig. 6
shows the drum closed to the other limit, thus allowing the position of the feathering
hooks G2, G², to be moved together with the binding arrangement, in their proper
relative position for placing the band round the bundle occording to the nature and
length of the crop.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
* 1st. Conveying the grain from that side of the main travelling wheel on which
the grain is cut, to the opposite side thereto by means of the vibrating needle
bracket.
2nd. Fixing the compressors on the vibrating needle bracket as described.
3rd. The rotary telescopic feeder as shown and described.
