Improvements in Harvesters.
I, ADAM CARLISLE BAMLETT of Thirsk, Yorkshire, Agricultural Engineer, do
hereby declare the nature of this invention to be as follows:-
The starting prong (which also acts as a sheaf compressor) is loosely mounted on
the needle shaft and held in position by the needle. It is furnished with a tail
piece which engages (on the starting of the binding mechanism) with a hooked
pawl jointed to an arm mounted loosely on the needic shaft and held in position by
a spring. Parts of the binding table on each side of the needle are hinged at their
upper ends, their lower ends resting on the front end of the starting prong which
assists in starting the binding mechanism.
The needle is actuated by a spring connecting rod attached to a crank pin on the
knotter wheel spindle and to an arm on the needle shaft, this arm is prolonged and
forms the starting arm.
When sufficient corn has been packed against the combined starting and
compressing prong the needle and starting arm are raised sufficiently to allow the
pawl on the packer or shaft to go into gear and actuate the needle in the usual
manner the sheaf being compressed between the needle and the combined starting
and compressing prong, and when the sheaf is bound and ready to be discharged
the needle in its descent unlocks the compressor prong by a projection in the
needle coming into contact with a spring push bar on the hooked pawl and allows
this prong to fall below the binder table, thus permitting the sheaf to be discharged
and on the descent of the needle this prong is raised into working position ready for
another sheaf.
The rotary string retainer is mounted behind the knotter spindle and rotating in
the opposite direction to that in practice it is mounted on a short spindle carrying
at its other end a worm wheel which is partially rotated by one or more skew teeth
on the periphery of the tier wheel, this retainer carries knives corresponding in
number to the notches in the retainer for holding the string, in its rotation it
carries the string with it until it is stopped by a projection on the fixed part of the
string retainer, against which the string is cut by one or other of the knives on the
rotary portion of the string retainer.

Improvements in Harvesters.
I, ADAM CARLISLE BAMLETT, of Thirsk, Yorkshire, Agricultural 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:—
The object of this invention is to simplify and render more certain in action, the
binding and the tying or knotting mechanism.
The starting prong (which also acts as a sheaf compressor) is loosely mounted on
the needle shaft and held in position by the needle. It is furnished with a tail
piece which engages (on the starting of the binding mechanism) with a hooked
pawl jointed to an arm mounted loosely on the needle shaft and held in position by

page_text: a spring. Parts of the binding table on each side of the needle are hinged at their
upper ends, their lower ends resting on the front end of the starting prong which
assists in starting the binding mechanism.
The needle is actuated by a spring connecting rod attached to a crank pin on the
knotter wheel spindle and to an arm on the needle shaft, this arm is prolonged and
forms the starting arm.
When sufficient corn has been packed against the combined starting and
compressing prong the needle and starting arm are raised sufficiently to allow the
pawl on the packer shaft to go into gear and actuate the needle in the usual
manner the sheaf being compressed between the needle and the combined starting
and compressing prong, and when the sheaf is bound and ready to be discharged
the needle in its descent unlocks the compressor prong by a projection on the
needle coming into contact with a spring push bar on the hooked pawl and allows
this prong to fall below the binder table, thus permitting the sheaf to be discharged
and on the descent of the needle this prong is raised into working position ready
for another sheaf.
The rotary string retainer is mounted behind the knotter spindle and rotating in
the opposite direction to that in practice it is mounted on a short spindle carrying
at its other end a worm wheel which is partially rotated by one or more skew teeth
on the periphery of the tier wheel, this retainer carries knives corresponding in
number to the notches in the retainer for holding the string in its rotation it carries
the string with it until it is stopped by a projection on the fixed part of the string
retainer, against which the string is cut by one or other of the knives on the
rotary portion of the string retainer.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a sectional elevation of the portion of the binding apparatus to which
my invention relates.
Figure 2 is a side elevation of the knotting mechanism with parts removed.
Figure 3 is a front elevation and Figure 4 is a rear elevation also in each case with
parts removed.
The remaining figures show detached portions of the mechanism, they are herein
after more fully described.
a a' is the starting prong and sheaf compressor to admit of adjustment made in
two parts, the prong a properly so called being separable, but when at work the
two parts are firmly bolted together.
The lever part is shown separately in side view and plan by the Figures 5 and 6.
b is the needle shaft on which the starting lever a is mounted so that it is free to
turn.
c is the needle, its arm c¹ is fast on the shaft b. In the usual way the needle
carries the string for binding the sheaves. a² is a lug upon the starting lever
against which the needle arm rests to hold the prong a¹ in place. The lug a² is
upon a tail piece a³ with which the hooked pawl d engages when the needle leaves
the lug a².
The pawl d is carried by an arm e loose on the shaft but held in position by the
spring link which at one end is connected with a fixed bracket 9. Figures 7
and 8 show this spring link separately.
is the binding table on to which the cut crop is continuously delivered and it is
pressed down by packers in the usual manner against the sheaf compressor and
starting prong a¹. ¹¹ are narrow parts of the table, one on either side of the
needle; they are hinged at their upper ends and at their lower ends rest upon the
arms a a of the starting prong lever. There are also other arms as a³ on
the starting prong lever which support the trap boards i i.
The needle c is actuated intermittently by the spring connecting rod k, this rod

page_text: notches of the string retainer. x is a trough form finger it operates in con-
junction with the rotating part of the string retainer and with the knife; it is
hinged to the frame of the knotter at ¹ and is pressed upon at the back by a
spring y.
Figure 20 is a front view and Figure 21 is a plan of the parts vw and x.
Figures 22 and 23 respectively show separately the parts w and a.
The action of the knotter is well understood and need not be described in
detail the string binding the sheaf is as usual laid by the needle c across the
nose of the knotter hooks and between the rotating string retainer and the
finger x. The spindle s makes a rotation during which the nose slaps the strings
around it, and its jaws open and grip the strings holding them until they are
cut, when the sheaf falling away (being pushed down by the action of the known
discharging arms not shown in the drawings) draws the ends of the string
(which in the meanwhile has been cut) out of the jaws and through the loop.
is the spring incline which as usual controls the action of the jaws,
rotating string retainer v makes one quarter of a revolution for each action.
The notch in which the strings are laid passes into the trough like hollow
of the finger x. The strings are carried round by the wheel which is then
operated by the inclines 1 and 2 until stopped by the shoulder 2 on the finger,
then when the part again moves on a step being operated by the incline
the strings are severed on the side next the sheaf but on the other side are still
held between the parts v and .r.
The
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what I'
claim is :-
1. Binding mechanism substantially as described in which the sheaf com-
presser a al is retained by a hook d carried by the arm e on the needle shaft and
the retaining link f.
2. Binding mechanism substantially as described in which parts h' of the packing
table are hinged and rest upon a combined sheaf compresser and starting prong
and aid in starting the mechanism when the sheaf is sufficiently packed.
3. Binding mechanism substantially as described in which movement is imparted
to the needle by the yielding connecting rod k and arm m on the needle shaft which
arm m being prolonged engages and disengages the clutch o.
4. A knotter substantially as described in which there is a rotating string
retainer with retaining notches and a knife w fixed to the part v and having
cutting edges immediately in rear of the notches v²; and in which also is a trough
like retaining finger x with a notch or stop a² holding back the string when it is
to be cut by the knife.
5. Binding and knotting mechanism substantially as represented by the annexed
drawings.
