Referring more particularly to Figs. 1 to 18, A is the needle shaft on the
driving end of which it carries a trip stop A¹, which acts to trip the clutch
connecting the pinion, a, with the driving shaft, A, the driving shaft being
connected by gearing a, a¹, a³, with the large gear wheel, a³, on the tier shaft.
The needle shaft also carries a crank arm A³, the outer end of which is connected
by a link b, b¹, with the rim of the gear wheel; a³. This link is made in two
parts b, b, and a wrist bolted to the gear wheel, a³, passes through an opening
made for it in head part, b¹ and bears upon a block and spring, b² (as shown in
detail Fig. 2) that in turn is supported by a plate, 63, and screws that pass through
plate, b³, into flanges 64, 64 on the head and thus the connection between the
wheel, a³, and needle shaft is made yielding. The trip stop A¹, has a hub 1, that
works loosely on the tier shaft and this hub has formed upon it a lug 2, from
which an arm, 3 projects in, parallel with a flange, 4, on the base 5, on the frame,
through which the needle shaft passes and an adjusting screw, 6, passes through a
threaded opening in arm, 3, and impinges against flange 4. The needle, C, is keyed
onto the shaft, A and a bell-crank, C' is slipped loosely onto the shaft, A, and lies
close up against one side of the needle. This bell crank has a lug, C² on its upper
arm that projects beneath the back edge of the needle, and the lower arm of this
bell crank has bolted to it, the two part trip arm D, the bolt, d, that secures
them, passing through curved slots d¹, in the trip arm by which the angle of the
arm D, to its supporting -bell-crank may be adjusted to give bundles of different
sizes. The butt ends of the parts forming the trip arm are concaved to fit snugly
against the needle shaft.
E is one of the tubular supporting bars that tie the binding frame to the
harvester and to this bar at a point about under the tripping arm I secure a
bracket E by a bolt, e. This bracket has two lugs, el el projecting from it to
which I hang a frame F. This frame is also connected with a lug, e², on
bracket E¹, below its hinge by a spring E². The frame F carries a sliding plate f
to which a catch, F1, is secured, after it has been passed down through a spiral
spring, b¹, and the head, f2, of this catch stands in position to engage with the inner
end of bell crank C. The frame F has a lug, g that projects up from it parallel
with the catch, and to this is pivoted à finger g¹ the free end of which is slightly
curved and provided with a shoulder at, g². This finger also carries a spring 93
that projects beneath the needle shaft and has a tendency to hold it down on said
shaft as shown for instance in Fig. 18 of the drawings.
The hub of the needle is provided with a lug c, for the finger, g'to engage with
when the needle is on its return.
The operation of the device is as follows:-
When the needle is at rest and is just ready to start, it is in the position shown
in Fig. 4 in dotted lines, its back edge resting upon the lug, C2 of the arm C¹, here
it rests until a sufficient amount of grain has been accumulated upon the com-
presser arm D to overcome the weight of the needle, which as before stated is
borne by the lug, C³, on arm, C¹, and when this occurs the needle will be tripped
forward far enough to partially revolve its shaft and through it lift the trip stop A¹
so as to free it from pawl H, on a pinion, a, loose on the driving shaft and by
connecting the pinion to the shaft thus throw the machine into gear, after this the
weight of the accumulating grain as it is packed against the compresser will be
taken by the catch, F, until the needle has encircled the gavel and has taken the

page_text: twine into the knotter and by this twine the lug c on the hub of the needle will bave
passed under the finger, gl, and beyond its shoulder therefore as the needle returns
after tying the knot, the lug, c, will abut against the shoulder, g, thrust the finger
back to throw the head f, of the catch F out of engagement with arm, C¹,
which when released at this point will permit arm D to fall into position shown in
full lines Fig. 15 as the bundle is discharged.
To prevent the cord from entangling with the packer adjacent to it, I provide a
shield I, which I secure to the upper end of beam K, in such a position as to
extend down between the line of travel of the needle and packer points.
The trip stop A¹ and crank arın As lie at an acute angle to each other and are
connected midway of their length by a strap A' which is slotted in its lower end
to take a securing bolt, A6, and when it is desired to make the trip more or less
sensitive the bolt A is loosened and the adjustment made by means of adjusting
screw, 6, after which bolt A is again tightened.
Referring now to Figs. 19 to 30, which illustrate the improved tying mechanism
A is the tyer wheel which is mounted as usual on the tyer-wheel A¹.
This wheel, A, has on its outer rim a cam flange, B which may carry its discharge
arm and this flange B has flared ends or extremities b, b' while its central portion
is straight.
C, is the knife bar which has secured to it near its center, the knife C and is
also cut out to form a finger, d.
This knife bar fits in ways in the breast-plate, a, and has on one end a stud C²
that carries a roller, c, for contact with the flango B. C is a spring one end of
which is secured to the breast-plate while the other rests against the inner edge of
the roller, c, and serves to retract the knife bar after it has been advanced to and
as it is released by the flange B. Above the cutter bar I secure an inclined and
tapering cord guide, d', to the breast plate, this guide projects over the needle
opening in the breast plate to receive the cord as the eye of the needle enters the
knotter.
The operation of the device is as follows:-Just after the cord bas been carried
about the gavel that portion of it between the knotter and the gavel lies across the
guide, d, as in Fig. 26 and the parts are so timed that at this moment the knotter
begins to turn and engages with the cord as in Fig. 27 drawing it off of the
guide d' from whence it falls to the finger, d, which latter supports it and prevents
it from falling down out of engagement with the bill while the loop is being made
and about this time the flange B begins to advance, the knife bar which completes
its travels, cuts the gavel cord and carries the finger, d, from under the cord and
permits the gavel to draw the knot down off the bill as soon as the knotter has
done its work. In other words the cord is first held by guide, d' in position to be
taken by the bill as it begins to turn and then after the bill has taken the cord the
latter is guided down on to the finger, d, and towards the shaft of the bill the
finger, d, preventing it from falling away from the bill until the loop is made and
then as the cord is cut the finger will be drawn from beneath it so as to permit
the bundle to drop to the rear and draw the knot off of the bill.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. The combination with the needle having a lug at or near its hub of the bell
crank carrying the compresser upon one arm, a spring catch for engagement with
the inner end of the other arm of the bell crank while the bundle is being com-
pressed, and a finger connecting the lug of the needle with the frame of the spring
catch for tripping the bell crank and allowing the compresser to fall, as and for
the purpose set forth.
2. The frame F, and brackets to which it is pivoted, in combination with
spring E³, spring catch, F¹, bell crank C₁, finger g needle having lug, c, and
compresser, as and for the purpose set forth.

page_text: 3. The frame, F, brackets E¹ spring E³, spring catch, F¹, bell crank C¹, finger, g¹,
and spring, g³, as and for the purpose set forth.
4. The flanged tyer-wheel in combination with the knife bar having finger, d,
and a guide attached to the breast plate and projecting partly across the needle
opening.
5. The combination of the tyer-wheel, its flared flange, B and the knife bar
baving finger d, with the cord guide d, as set forth.
6. The combination with a knife bar adapted to reciprocate across the breast-
plate and having a finger for supporting the cord until the loop is made of a guide
adapted to support the cord in position to be taken by the bill and to guide the
cord towards the shaft of the bill and down upon the finger.
