rods
I use the same cutting and elevating mechanism in this case, as that
set forth in my former Specification above referred to. The corner
slats D I now shape about as shown in Figures 1 and 2, one end being
hinged to the upper end of the inclined bars or slats E² to permit them
to be folded back as indicated in Figure 8. A hanger D is detachably
connected to the brace A¹ at k¹ on each side of the machine. These
hangers are fixed to the ends of the cross bar D' and the supporting
blocks D¹ to each of which a slot D is fixed and attached at proper dis-
tances to said cross bar. The horizontal portion of the slats at the lower
end are thereby suspended above the jacket or sheathing J' on the sliding.
frame, and the interstices between the slats D are entirely opened and
unobstructed, as shewn in Figure 2, from the line where the binder
arm B strikes into the extremity of the slats D. The supporting rails G
are pivoted to the bars G¹ at . These two side bars are framed together
by means of two cross bars or girts L and L, Figure 2, between the
rollers K. and K¹. The bars G are each provided with a track S¹, upon
which the reciprocating binder frame F is carried. The hangers S are
secured to the frame, and are each provided with two rollers, one above
and the other below the track. The upper ends of the braces B³ are
rigidly fixed to the pivoted bars, and their ends rest in sockets H' when
the frame is in its working position, as shown in Figure 1. The recipro
cating binder frame is composed of two side rails F and under the
jacket J¹ two cross bars F¹ and the posts F¹. The upper ends of the

page_text: latter are connected by a cross bar under the binder arm shaft Y. This
shaft is mounted in suitable boxes upon the top of the posts F¹. The
arm C is keyed to this shaft to sustain about the relative arrangement to
the binder arm B as that shewn by the full lines in Figure 1. The arm B
may be made adjustable laterally across the machine, substantially as
shown in my said former Specification. The take-up bar T is pivoted to
the binder arm and the lower end is provided with a roller r, that bears
against the curved plate I, which is fixed to the cross girt at the top of
the posts. This plate I should be of sufficient length to admit of any
desired amount of change in the adjustment of the binder arm. The
wire reel W' I mount upon the take-up bar T. The latter is provided
with a grooved roller or pulley at m³, also one at m², and the binder arm
has a pully at m¹. The wire passes from the reel to the roller m³,
thence to m', and from that to me, and from that to the eye in the
end of the binder arm at x. The rod or bar T is pivoted to the binder
arm near m², and passes loosely through a loop fixed to the side of the
take-up bar. The set nuts p' may be adjusted to rest upon the fixed
loop through which the rod passes when the binder arm is in its extreme
downward position, and the rod is thereby made to hold the take-up bar
and prevent any springing of the same by the strain of the wire when
drawn around a gavel, thus preventing the drawing of the wire through
the end of the binder arm or out of the grasp of the clamping jaw after
being severed by the twister hook or its being broken.
It will be seen that when the binder arm is in the position of the
dotted lines at x, Figure 1, the wire pulleys m', m², m³, are very near
each other, but as the arm descends these points are separated. This
action causes a quantity of wire to be reeled off, the end having been
previously passed through the eye in the end of the arm B and fastened
there; and when the arm is returned to its upper position the descending
grain from between the slats D and the guards E will readily cause this
slack to assume the form of a curve similar to that indicated by the
dotted curve Z, and when the arm again descends to encircle the gavel
with the wire the former is permitted to readily assume a round or
circular form.
The compressing arm y, Figure 1, is preferably pivoted to the binder
arm at y, and the other end is hinged to the brace rod y³, which
The head of the
passes loosely through the lug v on the binder arm.
rod y² prevents it from ever becoming detached from the lug. At a

page_text: suitable distance below this lug the rod is provided with a shoulder or
collar, between which and the lug is placed a compressing spring y*.
The position of the binder arm and compressor, as shown in Fig. 1,
represent the parts as when receiving a gavel or quantity of grain to
form a bundle. The tension of the spring y' may be made adjustable 5
by making the collar y to slide on the rod y' and having its position or
adjustment controlled by a nut or otherwise.
The metallic jacket or sheathing J¹ may be made in three or more
sections, those at the ends being made to overlap the central section.
The latter is moveable with the twister frame and has an opening to admit 1
the end of the binder arm with the wire. They are provided with open
loops on each side, as shown at q, Fig. 3, and these catch around the pins
inserted in the bars and a hasp loop n', Figure 1, over a staple, in
which position the parts are secured by the hook p.
The belt B' is attached to the front and rear cross bars F of the sliding 1
frame and passes over the rollers K and K'. This belt may be made of
ordinary canvas or any other suitable material, and is designed to prevent
straws and dirt from dropping into the wire twisting apparatus, and the
clamping jaws and their operative mechanism.
There are several sustaining fingers Q₁ fixed to the rear bar F* of the
sliding frame for the purpose of retaining one bundle at least upon the
binding frame until the next succeeding one is being encircled or com-
pressed by or with the binding wire, thus insuring a more perfect
separation. These fingers Qmight be fixed to a separate bar hung
between the pivoted arms G in rear of the belt roller K if desired, or a g
close shelf might be employed and attached in either position. The
cushioned draft loops H are bolted to the posts F' of the sliding frame.
They are made, as shown in Figures 1 and 10, to receive the ends of
the crank arms C when they are to draw the binder frame in. The
sockets S³ of these stops are preferably provided with a cushion Tof
rubber, felt, or other suitable material, to relieve the parts from the con-
cussion otherwise produced by the end of the cranks C striking the
sockets. A metallic spring would serve the same purpose.
The roller R, which is the driving roller of the elevating belt, I
provide with several yielding carrier bolts o; these consist of a small
bolt having a slight enlargement or shoulder at such a distance from the
outer end as to permit it to project through the plate which secures it in
its place in the roller, and to catch against the cross bars t³ of the clevator

page_text: belt E. This bolt is rendered yielding by means of a springs whereby
if a cross bar should happen, as may occur, to come upon the end of the
said carrier bolt, as shewn in Figure 9, in full lines, the spring would
allow the bolt to retract, and thus avoid breaking or straining the
belt.
The divider fingers F² may be curved, as shewn in Figure 1, or they
may be made of thin plates constructed with a wide base as indicated by.
the spaco between the curved line 1 and the dotted line Y¹. The latter
shape would undoubtedly effect a more perfect separation or division of
the mass of grain stalks. These fingers are fixed to a cross bar extending
from one arm ' to the opposite onc. These are hung to the axial shaft
of the elevator roller R, and are operated by a connecting rod Z' which
is driven by a cam upon the shaft n¹.
The fingers F may be made to work between the slats D or through
openings made in them for that purpose.
The binder arm B is operated by means of the levers or crank arms O
from the driving crank C¹ through the connections C³, as will be seen,
when the driving crank is at w the binder arm would be at x, as the
crank passes up to w¹ the binder arm is carried down to x¹, and when.
the crank reaches to the end of the binder arm will have entered the
twister frame at a², and as the crank C¹ moves beyond this point, the
binder arm preventing the crank C from turning any further upon its
axis, the sliding carriage or binder frame is thrown back to the position
shown by heavy dotted lines. As the crauk C¹ moves towards w0%
the end of the cranks C is brought into the sockets S³ of the stirrups H
and raises the binder arm to the upper position indicated at x1, and when
the crank C¹ reaches the point to the reciprocating frame is returned to
the position shown in full lines. The binder arm and twister should be
adjusted so as to register to one of the openings or interstices between
the slats D, which being opened out to the end of said slats, the end of
the binder arm is allowed to swing down into the twister frame and
remain there while the frame F is thrown back, and furthermore there is
no obstruction to the straw and other substances.
It is obvious that owing to the above-described construction of these
parts whenever the crank C is not in contact with the sockets S³, the
reciprocating frame will be liable to move back or forth by the jostlings
of the machine, or when the gavel is being compressed or encircled by

page_text: the binder arm. To prevent this difficulty I provide the locking cam J,
which is shaped as shown, and is pivoted to the sill of the machine at u.
The upper or swinging portion is connected by the pitman or con-
nection C³ to the sliding frame, whereby the latter is firmly held in the
desired position at all times.
While the crank is passing from w to w² the sliding frame is held at
rest, and while it is passing from w² to to the said frame is thrown out,
as indicated at the heavy dotted lines, where it is again held at rest
while the crank passes around to w³, and the frame is returned while the
former is swinging from w' to w.
The shaft n' and locking cam J may be hung higher up in the
machine, if desired, by any suitable arrangement of gearing and shafting
to prevent the dropping of the lower portion of the can or guard, and
also the crank C¹ driving that portion of the sweep of the latter below
the sill of the machine.
Any other style of automatically-acting lock might be substituted for
the cam J, for instance, toggle-jointed levers connected to the sliding
frame and to some fixed portion of the machine, and made to be tripped
at the proper time by the cranks C₁or the connecting rods C², or other-
wise, might be employed.
The stock M, Figure 2, to which is attached the wire clamping jaws
and twisting mechanism is hung between the cross bars or girts F* of
the reciprocating binding frame by means of the looped hangers O
which permit the stock to be adjusted to any desired position laterally
across the machine, and at the same time servo as a tie between the
bars F.
It will be seen that the twisting apparatus in this case occupies a
horizontal position instead of being vertical or inclined, as in the
machine described in the Specification of the said former Letters
Patent.
The wire-clamping jaws are made and arranged to operate substan-
tially in the manner set forth in the said former Specification, except
the nearer or under jaw N attached to the rod N¹, which I now make as
shewn in Figure 6. This construction of the jaw has been found to
work far more satisfactorily than the former construction. The point
of the jaw at a being shortened so as to be entirely withdrawn from the

page_text: open slotted end of the fixed jaw a³, causes it to effectually discharge
any fragment of wire or severed ends of the band at each stroke or
operation of the jaw. The wire is looped around the finger f* and
forced thereby against the fixed jaw and partially into the open mortise
in the end, whereby said wire is firmly held while the binder arm rises
to its open position to receive a bundle of gavel, and while it is
encircling the same with the wire. The mortise is formed by the metal
loop, shown by the dotted line a³, Figure 6, on the under side of the
fixed jaw a³.
I also provide a centering jaw v², shown detached in Figure 7, to ensure
the delivery of the wire to the grasp of the twister hook at the proper
time. I have found that during the time the binder frame is returning
to receive each succeeding gavel there is a liability of the backward
revolutions of the twister hook, which takes place at the same time, to
cut off the wire thus strained across the track of the points thereof. I
obviate this difficulty by means of the bar b, Figures 2, 4, and 6, pivoted
to the under side of the face plate P. This bar constitutes a sort of bell
crank, and the opposite arm b' is slotted, as shown, or otherwise con-
nected with a pivot on the arm or rod N of the jaw a, so that when this
jaw is open or withdrawn, as shown in Figure 4, the arm 6 is thrown
forward, as shown, and bears the wire with it beyond the track of the
revolving twister hook. The latter is operated by means of a simple
rack o¹, Figures 2, 3, 5, and pinion 71, Figures 3, 4, the former being
carried or sustained in the hanger V, by which it is suspended between.
the cross girts or bars L, L', of the pivoted supporting bars G. When
the reciprocating frame and stock M' move in the direction indicated by
the dotted arrow in Figure 2 the twister hook &¹ is made to rotate forward.
so as to cut off and twist the ends of the band together, and when they
move in the direction of the full line arrow the direction of rotation of.
the twister hook is reversed.
The rack o¹ is made somewhat shorter than the distance between the
bars L, L', to afford a short interval of rest for the twister hook at the
end of each reciprocation more than is occupied by the frame, that is to
say, the frame moves a short distance either way in commencing a return
stroke, carrying the rack with it, before the end of the latter strikes the
bar L or L'. This distance indicated at c², Figure 2, may be made more.
or less, according to the length of time the twister is desired to remain
at rest, which rest is for the purpose of enabling the wire clamping jaws

page_text: to act, the upper one a to grasp the ends of the encircling band, and the
lower onc N2 to release the wire previously held by it before the twister
commences its revolutions. The wire clamping jaws a and N2 are con-
nected with and operated by the rods N and N¹ and their springs, which
are relatively arranged the same as those shown in my aforesaid former
Specification, but the rods are connected in the following manner :-'
:-To
the under side of the stock M¹ is bolted a hanger plate S², Figures 2, 3,
which sustain a narrow bed plate d that extends from the bar L to the
bar L', or nearly so, as shewn in Figure 2. This plate is fitted to slide
freely in its track or bearing in the hanger. The switch track t¹ is fixed
to the plate d, as shewn in Figure 2, with its beveled section at v' out of
line with that of t. The latter is also fixed to the plate d. At the end
of the plate opposite is arranged the star wheel j, which is permitted
to revolve in the direction of the arrow, but prevented from turning in
the opposite direction by the spring dog or pawl 9%. The lower portion
of the lever which connects the rods N and N' is provided with rollers
e, e. The roller e works between the jaws M of the stock M¹. The
roller et is made to travel at either side of the track t in the following
manner: As the stock moves in the direction of the dotted arrow,
Figure 2, the several parts occupy their position shewn in full lines.
When the roller et arrives at the point m it comes in contact with an
arm of the star wheel j, which turns and carries the roller to the position
indicated by the dotted lines at n, and as the said stock M' starts in the
direction indicated by the full line arrow the roller is forced over upon
the other side of the track, as indicated by the dotted lines e³, Figure 3,
the lever swinging in the end of the rod or spindle N¹ as a fulcrum, the
upper end of the lever assuming the position indicated by the dotted
lines withdraws the rod N and opens the upper jaw a, as shown in
Figure 4. The roller e' travels upon that side of the track indicated by
the dotted lines e³, while the stock M¹ moves in the direction of the full
line arrow, and holds the upper jaw a open and the other one N° closed
until the roller arrives at the point k, where it drops upon the face v' of
the track, and as the stock M³ is carried back by the opposite recipro-
cation of the binder frame the pulley e' is forced up the inclined plane
to the point t, Figure 2, thus closing the upper jaw a and opening the
lower one N. The same position of the roller e' is represented by the
dotted lines e² in Figure 3, the end of the upper rod becoming the fulcrum
in this case, and the lower one N¹ being withdrawn, as indicated by the
dotted lines i; since the lower jaw only requires to be open for a short

page_text: interval the roller e' is immediately allowed to return to its normal
position and the various operations are repeated. The movements of the
jaws and their actuating mechanism must be timed to correspond with
those of the binder arm and other gaveling and binding devices.
The lower end of the brace B² may be locked to the socket H² by a
hook or other suitable means. The guard or clearing yoke o² may be
composed of a single plate bent in the form of a bow, the ends being
pivoted near the end of the binder arm, as shown in Figures 1, 11, and
it is forced to the position shown by the full lines by the spring h²,
except when the binder arm enters the twister, when it is brought into
the position indicated by the dotted lines in Figure 1. This device is
designed to prevent the catching of the side projections in the straw
when entering the grain.
To insure the proper delivery of the bundles from the horizontal
portion of the slots D I provide the brackets d', which are preferably
attached to the jacket J¹, as shown in Figure 12. They are shaped, as
shewn, to enable them to be readily carried under the grain or gavel as
the binder frame moves forward, and to cause them to catch the bundle
when it moves back, and discharge the same from the slats. There may
be one or more fixed to cach of the end jackets, and they should be so
arranged as to register to the interstices between the slats. If there is
no gavel to be bound when the arm descends at any time the slack wire
will be temporarily taken up, as above described, by that movement of
the parts, and as the arm rises it will be again released. Thus it will be
seen that the quantity of slack wire is not increased by a repetition of the
movements of the binder arm under such circumstances, which is of the
greatest importance. The quantity of the slack may however be regulated
by using a longer or a shorter take-up lever, or by changing the relative
position of the wire pulleys m³, m³, and m³. These latter should all have
some sort of guard loop to prevent their unthreading or discharging the
wire.
The machine is folded up, as shewn in Figure 8, to permit it to be
drawn through gateways. The bolts ¹ arc first removed; the parts can
then be swung into this position.
Instead of the locking cam J the connection C³ might be provided
with a toggle joint, and the end now attached to the cam J might be
pivoted to the side bar G. This contrivance would lock the binder framę

page_text: in its outer position until the joint was tripped, which might be done by
a lug fixed to the pitman C. The frame might be locked in its inner
position by a similar toggle-jointed lever, having one end pivoted to tho
cross bar L, and the other to a lug fixed to the under side of bar F.
This lever should fold horizontally after being tripped. Instead of the
brackets da pivoted bar with rake teeth arranged to rise and fall by the
reciprocation of the binder frame or carriage might be employed.
