IMPROVEMENT IN GRAIN BINDING HARVESTERS
Year: 1884

page_text: I, JOHN OWDEN O'BRIEN care of Wm P. Thompson and Cos. Agency for Foreign
Patent Solicitors, 6, Lord Street Liverpool, in the County of Lancaster Engineer
do hereby declare the nature of the said invention for "IMPROVEMENT IN GRAIN
BINDING HARVESTERS," (a communication from abroad by William R. Baker and
Henry E. Pridinore both of Chicago, Cook County, State of Illinois United States
of America Engineers) to be as follows:-
"
This invention may be enumerated under the following heads': First, as relates
to a device hereinafter termed the "table trip" designed as an improvement upon
one formerly used mainly to prevent choking of the grain in the binding passage
and start the machine independently of the ordinary trip when such choking
occurred. Second, as relates to improvements in the usual finger trip, enabling it
to co-operate with the new table trip: Third, as relates to the slack lever and
tension, which are herein made to cooperate by a single spring, and the former of
which serves to lock the pinion that carries its controlling cam, in order to hold the
mechanism steady and in place until tripped: Fourth, as relates to the addition of
a cord hook to the cord guide heretofore used with the knotter or
tying bill" in
modern binders whereby the cord after being guided into place for the action of the
knotter, is prevented, between the knotter and holder, from slipping too low for
said knotter: Fifth, as relates to the frame of the binder which is of steel, so far as
possible of skeleton outline, to dispense with the cumbrous and heavy wood and
iron work of the former construction: Sixth, as relates to means for operating the
cord holding disc, consisting in a hooked pitman suitably guided and catching into
a ratchet on said disc. Seventh, as relates to the sway bar for driving the cutter
bar or sickle, which sway-bar instead of being carried transversely through or
beneath the harvester platform is now placed in the space beneath the elevator,
parallel with the side of the main wheel, and connected directly with the heel of
the sickle Eighth, as relates to the angle iron supporting the guard fingers of the
cutting apparatus and affording a way for the sickle bar, which angle, iron is herein
extended beyond the point where the sway bar connects with the heel of the sickle
.

page_text: to sustain the latter in its place and has its upper web bolted to the front sill of the
clevator at, points on each side of the sickle heel: Ninth as relates to novel means
for tightening the platform apron, whereby said apron may be tightened by a single
instrumentality, and may be adjusted as to its connection with such instrumentality
to keep its surface evenly controlled thereby: Tenth, as relates to a bundle-carrier
which receives and retains the bound sheaves until sufficient have accumulated to
form a shock when it is thrown by the driver into friction connection with the
gearing of the harvester, and is thereby opened for the discharge of said sheaves;
Eleventh, as relates to means for holding the adjustable main wheel rigidly in its
adjusted position.
A type of binder well known in England during the past season may be referred
to in illustration of these improvements although some of these features will be
found applicable to machines differing in structure. In such type the grain was
received on a platform apron, carried up an elevator at the inner end of this apron,
and discharged into a descending grain-chute, where it was urged forward wisp-by-
wisp or bunch-by-bunch by alternating packer arms against tripping fingers which
closed the outer side of the chute. A section of the table or decking in the chute
was hinged and connected with the tripping device so that in case the grain lodged
in the passage way before reaching the trip fingers it might press upon the hinged
section and thus start the trip.
One of the packing arms operated through a slot in this section while the other
arm operated through a slot in the stationary part of the decking. The trip clutch
on a shaft operated from the harvester was connected with the trip fingers and
hinged section of the deck or table trip as it was called so as to be thrown into
engagement with a loose pinion on said shaft by the starting of either of these
tripping agencies and this pinion when engaged drove by means of two intermediate
idle-wheels a gear-and-cam-wheel on the binder shaft whereby the knotter, holder
and cutter, the binding arm and the support for the outside trip fingers were
actuated. A slack lever controlled by a cam on one of these idle wheels was also
.employed to take up and give out the slack in the cord at proper intervals.
Now referring to the first head of this improvement, instead of the hinged
wooden section of the table a narrow forked or slotted metal frame is employed, the
two arms of which extend along the sides of the slot for the binder arm and are
raised or ribbed sufficiently to rise considerably above the surface of the deck.
This frame is hinged at the head of said slot and extends down therefrom until its
lower end reaches and passes between the outside trip fingers being free to play up
and down there-between. It rests upon an arm from the trip rock-shaft so that
when depressed by the accumulation or obstruction of grain above it, it will press
down said arm and rock the shaft.
On the binder arm shaft which it will be understood subtends the grain table or
deck), or on the heel of the binder arm which is on said shaft, are placed lugs in
such position that as the binder arm rises and approaches the end of its ascent in
the binding operation following the action of the trip, they strike the metal frame
or table trip, and lift it to give an additional compression to the sheaf over that
given by the packers and binding cord.
As to the second head of invention; a two armed casting is made fast to the
rocking trip shaft, one arm of which extends inwardly towards the main wheel and
supports the under side of the table trip, the other arm extending outwardly to one
side of and beneath, the pivoted trip fingers where it rests upon a lug on a heel
extension from one or both, so that as they are pushed back upon their pivot they
will lift this arm and rock the trip shaft while the table trip whenever depressed
⚫ will push down the opposite arm, rocking the trip shaft in the same direction; thus
the trip dog will be unlatched from the trip clutch. by the proper movement of
either of these devices under pressure of the grain. The tripping fingers are bolted
to a block with capacity for adjustment back and forth along said block, and this
block, which forms their above styled heel extension, instead of being pivoted upon
supporting arms binged to the heel of the binder arm and sustained by links from

page_text: an underlying rock shaft, as heretofore, is mounted directly upon a rock shaft
subtending the binding table near its outer edge, and plays upon said shaft as
a pivot. The links which control the heels of the packer-arms are also pivotally
suspended from this shaft. Keyed fast to said shaft, alongside the supporting block
or heel piece of the tripping fingers, is a casting having a lateral pin or lug which
takes into a lateral slot in said heel piece, and having also a radially extending arm
link connected with the tail board of the binding receptacle so that whenever the
shaft is rocked said casting may both swing the trip fingers back with it and open
the tail board.
A crank on the end of this rock shaft is connected with the gear-and-cam-wheel
by an elastic pitman and T-head similar to the one formerly used for opening and
closing the aforesaid supporting bar, so that when the binding mechanism starts
the shaft will be operated.
As the connection between the tripping fingers and the casting fixed to the rock
shaft is by slot and pin said fingers are permitted to swing back on the shaft under
the pressure of the incoming grain a sufficient distance to start the trip, provided
they are previously held in such position that the pin is at the outer end of the
slot. This is accomplished by the arm or lever from the trip rock shaft, which at
its extreme end beyond the lug or socket in which it rests, is brought against the
over crowning curved base of one or both of the trip fingers whenever the binding
operation is finished, by means of a lug or shoulder on the binding arm shaft
striking a stop on the trip dog as the binding arm falls to its position of rest and
forcing it down against the lifting finger on the trip shaft which is thereby rocked
and forcibly lifts the lever arm against the said base, whereby the trip fingers are
swung inward as far as they are allowed to go. The spring which holds down the
trip-dog aids materially in this result, and may even entirely accomplish it though
not so reliable.
Third The slack-lever lias heretofore been pivoted on the front board of the
binder and its heel provided with a roller which travelled upon a cam on one of
the idle-wheels driven from the trip pinion so that its front end would be raised or
depressed at proper intervals to take up or give out slack in the cord which run
through an eye therein and through guides on either side. This slack lever it is
now proposed to provide with a tension finger resting upon the cord running
through at the front end, for this purpose the lever having two eyes at said end
between which the finger passes to press upon the cord-The finger is pivoted on
the lever and by means of a coiled spring peculiarly arranged and connected with
a novel casting supporting the lever pivot, is held down upon said lever, while
at the same time by the same spring the heel of the lever is pressed against its
controlling cam. At that point where the heel of the lever comes at the moment
the binder is thrown out of operation the cam is notched so that the heel pressed
forcibly up by the spring, will rise into said notch to hold the idle wheel out of
motion to keep the binder mechanism steady and also to prevent back-motion.
It has been heretofore customary for this purpose to employ a locking device upon
the gear and cam wheel, but in the present instance it will be observed the locking
device is applied to the idle pinion next to the driving pinion and is furnished by
a slack lever and its cam, thus placing double functions on the latter two. An
additional feature of this arrangement is that the casting which supports the slack
lever is bolted upon the lower brace of the binder instead of upon the side or end
board as heretofore, securing a much firmer construction and permitting adjustment,
which was not possible formerly.
Fourth For a year or two past a cord guide has been placed in the holder and
knotter frame so arranged that as the binding arm entered said frame to deliver
the end of the cord to the holder it would pass along said guide and the strand
would be directed onto the knotter, and kept steady between the knotter and
holder while the former was operating. This finger however was not entirely
efficient as, its end being open, the cord between the knotter and holder sometimes
slipped too low for the action of the knotter, therefore in the present invention the

page_text: end of the guide is reversely curved to form a hook which entirely-prevents the
escape of the cord until the knot has been formed and the strands cut.
Fifth. The frame of the binder has heretofore been composed of heavy wooden
bars and cumbrous iron castings which are herein replaced by steel bars or
brackets formed with half boxes for the various shafts and so far as possible of
skeleton outline.
Sixth. At the rear end of the binder shaft is a wheel having a peripheral section
of gear teeth and a delay track, and also upon its face a cam ledge. Supported in
a bearing or bearings in the bracket casting which sustains the rear of the binder-
shaft, opposite the lower inner quadrant of the wheel; is a short shaft or spindle
provided with a pinion and delay shoe to engage with and match the gear section
and delay-track upon the just mentioned cam wheel. The pinion is of such size.as
to be given one revolution by the gear section while the delay-shoe locks with. the
delay track in the intervals between the revolutions and prevents motion. The
-end of the shaft away from the pinion, and about the centre of the holder-frame, is
cranked and has a wrist pin whereby motion is to be intermediately communicated
to the holder disc.
This short shaft, hereinafter called the "holder shaft" affords one of the journals
for the holder frame, which is intended to rise as the knotter demands slack from
the cord ends in the tying operation, the other journal being located upon the
bracket casting in axial prolongation with the shaft.
A heel projection rises from the holder-frame alongside the wheel on the binder
shaft, and a roller from this projection bears against the cam track or ledge on said
wheel, whereby the frame will be pressed down, away from the knotter, during the
proper intervals, and then allowed to rise to yield slack as demanded. "In the
usual position on the holder frame is journalled a notched holder disc held against
retrogression by a click, and saddled at one edge by a spring pressed clamping shoe,
such as has heretofore been known. A ratchet wheel is secured beneath the holder
disc as customary, whereby it is to be driven.
Upon the wrist pin from the holder-shaft is loosely mounted a block or sleeve
having a lateral arm or lug to the end of which the heel of a pawl is pivoted.
A spring is rivetted or otherwise secured to the lateral arm, or to the sleeve in
such position as to press at its free end against the back of the dog and force it
towards the ratchet beneath the holder disc, and said dog is guided and prevented
from circling about the wrist pin by means of a smooth or planed way upon the
frame arm which extends beneath and supports the disc and ratchet, and on the
other side by the overcrowning disc, or by the click which is so arranged as to
bridge it. Undue pivotal play is also guarded against in one direction by a lug
rising from the frame arm behind the dog, and in the other, of course, by the
ratchet.
The point of the dog is preferably hooked so as to catch into and pull upon the
ratchet as it is drawn back by the revolution of the wrist pin, but it may be
pointed to push upon the ratchet, the teeth of the latter. being correspondingly
reversed.
"
F
In order to take up or compensate for wear, either 'the arm to which the dog is
pivoted will be inade in two sections, one adjustable lengthwise of the other, or
else the dog itself will be bi-membral and extensible. The latter is the most
convenient resort, the heel section of the dog being pivoted to the arm at one
end and at the other milled or serrated on one face and the nose section corre-
spondingly milled or serrated on the contiguous face and connected thereto by slot
and clamping screw, to permit any reasonable range of adjustment.
Seventh-Sway bars have been formerly carried through or beneath the harvester
platform and connected with. the sickle at the middle of the length of said sickle.
This either involved cutting through and weakening the front and rear sills for the
admission of the sway bar to the cutter bar or required the sway bar at its forward
end to make connection with the sickle by a bend or crank which was easily
broken by the heavy labour imposed upon it. Instead of this arrangement in the

page_text: present invention the sway bar is carried beneath the elevator alongside of the
main wheel and between said wheel and the ascending side of the said elevator
frame and is pivoted nearly opposite the axle of the main wheel and driven by a
pitmän from a crank shaft on the outer side of the main wheel at the rear of the
machine. The heel of the cutter bar or sickle is extended so as to directly connect
with the front end of the sway bar.
Preferably the sway bar is inclined bringing its rear end just above the rear sill
of the elevator frame while the front end extends beneath the front sill of said
frame which over lies the front sill ör timber of the platform frame. The pivot of
the sway bar is therefore made slightly compensatory as well for this reason as
because the rear end of the sway bar where it connects with the pitman is
intended to be suspended by a pendulum froin the elevator frame to avoid the
thumping which would otherwise ensue from the action of the pitman.
Instead of constructing this sway bar of wood as usual it is made of two bars of
steel bent and relatively inverted to form trusses, braced at the centre by a bridge
or block of malleable iron which affords the pivot journal and with their ends
connected by other blocks or caps one of which serves to connect the sway bar with
the heel of the sickle and the other, for the ättachment of the pitman and pendulum.
A very light and strong sway bar is thus secured.
Eighth. The angle iron which is bolted by its lower web to the front sill of the
harvester extends along said sill to support the heel of the sickle and together with
said front sill is connected with the front sill of the elevator frame at two or more
points by means of bolts passing througli its upper web, the two sills and inter-
mediate blocks, and serves thus to greatly brace and strengthen the connection
between elevator-frame and harvester frame. Between two of these blocks or
points of attachment the front of the sway bar plays and the angle bar therefore
while increasing the strength and security of the union between the two sills affords
also a ledge or way to support the heel of the sickle and end of the sway-bar in
their movement.
Ninth. The platform apron is passed around drums at each end and is joined at
its ends by straps and .buckles from four to six in number, which serve to properly
stretch it upon the drums at the out-sét, but which take considerable time in
adjustment, and are therefore undesirable for future adjustments when the belt is
not unevenly stretched or whenever the entire apron has become slack.
For this reason one of the platform drums, usually that one nearest the divider,
has been supported in sliding boxes and a take up screw applied to each box so
that by turning these two screws that roller of drum would be moved up against
the apron tightening it throughout its whole width. This also while an improve-
ment is deficient in this respect that it requires two independent operations and
nice correlation between the two. Herein the boxes at each end of the outside
roller or drum are connected with a single instrumentality whereby they may be
simultaneously moved and co-ordinately adjusted and whereby any discrepancy in
the strain upon each box through that instrumentality may be compensated for.
This arrangement is as follows:-The drum is mounted in bearings at the end of
slotted sliding bars having grooves or ways on each side of the slot and intended to
rest upon the top of the front and of the rear sills respectively.
Outside of the journals and playing through apertures in the grain-board are
hooked arms integral with the bars and intended to receive loops formed, on the
ends of wire cords or ropes. The cord from the front sliding box is led over a
horizontal sheave or a guide pulley mounted in a bracket bolted to a standard ör
upright post supporting the outside divider and from thence passes to the rear
outside corner of the platform: Upon the grain board of any suitable support at
this rear outside corner is a second bracket practically in line with the rear sliding
box. Two sheaves or pulleys one of which has an enlarged disc with a segment
rack on its periphery and is cupped on the exposed face of said disc and milled or
radially serrated at the bottom of the cup, and the other of which is provided with
correspondingly milled or serrated disc adapted to sit in the cup are arranged

page_text: within this bracket. One of the sheaves has a journal hub entering a bearing in
said bracket and provided with a screw threaded bore while the other pulley is
bored in line therewith and receives a bolt passed through the opposite bearing in
the bracket and enlarged at its shank to form a journal within said bearing and a
shoulder to press against the surface of the sheave. The end of the bolt is screw
threaded to engage with the threads in the above mentioned hub whereby the
two pulleys or sheaves can be clamped togethed in any desired circumferential
adjustment. A pawl or dog is arranged upon the bracket so as to take into the
ratchet seginent. and hold the sheaves against strain upon them, and a thumb
piece on the pawl enables it to be thrown out of engagement whenever it is desired
to turn the sheaves. Upon the journal hub is formed a square or polygonal. head
to receive a wrench, or some other suitable. device is attached thereto or connected
therewith, whereby the sheaves may be turned when it is desired to stretch the
belt. Each sheave has a pin to receive a loop on the end of a cord led to it from
one of the sliding boxes. One of the sheaves receives a long cord from the front
box over, the guide pulley as just described and the other sheave receives a short
cord from the rear box, stretched directly to it since its outer periphery is in line
with the hook on said box. Now by winding up the sheaves by means of the
wrench, or other device employed both cords will be taken in uniformly since the
sheaves being of similar diameter rigidly bolted together will move as one. In
case however one cord should be stretched or not properly proportioned to the
other so that the drum is moved first at one end and not simultaneously started at
both ends, the pivot bolt will be loosened and the proper sheave turned relatively
to the other until the tension on both cords, when the drum is exactly parallel
.with its companion, is uniform. The bolt will then be driven home and the
sheaves again clamped together, forming practically a single winch which will
thereafter, and until one of the cords again stretches, move the drum co-ordinately
at each end while preserving its parallelism.
As a modification a pinion may be substituted for one of the sheaves, and a rack
replace the hooked arm upon the adjacent sliding bar, the pinion being so propor-
tioned and adjustable with reference to the remaining sheave that the boxes at each
end of the apron drum will still be moved alike.
.
Tenth-The bundle carrier is a light receptacle preferably of a sort of lattice
work of wooden slats bound together by metal straps. On the stubble side it is
backed or built up to prevent the escape of sheaves but at the ends it may be open.
When down its bottom is level or nearly so, and is closed on the inner side only
by independent inclined chute, preferably a hinged board, which lies beneath the
tail of the binding receptacle and conducts the bound sheaves into the carrier.
The carrier is swung by bails from frame timbers out set from the barvester in
such manner that whenever thrown open' it will gravitate again to its closed
position. A lever arm rises from the back of the carrier to which it is bolted and
at its upper end has a sheave. Upon the top board of the elevator frame and at
the rear thereof is placed a bracket supporting fixedly a short shaft or spindle and
upon this shaft is loosely mounted a spur and friction gear driven constantly by an
intermediate idler from a wheel on the rear gudgeon of the upper elevator roller.
A drum is also mounted loosely upon said shaft so as to be moved into friction
contact with the gear. Beyond the drum is a thimble encircling the shaft close to
the hub of said drum, then loosely bridging the adjacent standard so as to be still
allowed end wise play and finally capping and being steadied by the protruding end
of the shaft.
Against the capped end of the thimble presses one end of a cranked lever pivoted
near the drum and thence extending downwards along the inner rear strut of the
elevator to a position near the seat standard, where its lower end is connected by
a link or strap with a foot treadle convenient for operation by the driver.. Thus
whenever the treadle is operated, or the strap pressed upon; the thimble will be
pushed against the hub of the drum and the latter forced into effective engagement
with, the friction gear or a friction clutch rigid with the spur pinion and begins to

page_text: revolve. One end of a cord or band is attached to the drum and the other led over
the sheave on the lever arm from the bundle carrier and then returned back to the
neighbourhood of the drum and made fast to the supporting bracket. (The cord
may however be tied directly to the end of the lever and the sheave omitted.)
Near to the drum the cord-runs through a fixed guide and at a suitable distance
therefrom, between the guide and lever, it has adjustably secured to itself a small
block or stop..
.
It is evident now that while the drum is idle the bundle carrier will remain
closed, but whenever the drum is pressed into and held in frictional engagement
with its driving gear it will wind up the cord and open the carrier and will
continue winding until the stop on the cord comes in contact with the fixed guide
which will be at the moment the carrier is fully open. The positive resistance of
the cord will now prevent the drum from turning with the gear, and the carrier
will be held stationary, for the full discharge of its load until the driver releases
the treadle, when, the friction grip upon the drum ceasing, the carrier will gravitato
back to place.
Eleventh. Of late years the axle supporting the main wheel of the harvester has
been provided with fixed pinions which engage with and turn upon segment racks
formed in upright bridle standards fixed to the lateral bars of the wheel frame.
A sheave pinned to the axle receives one end of a chain, the other end of which is
wound upon a drum on one of the longitudinal sills of the harvester frame, usually
the rear sill, and when this drum is turned in one direction or the other, the axle
is revolved either by the stress brought upon the chain as it is taken in, or by the
descending pressure of the harvester frame upon the pinions as said chain is let out,
so that the position of the wheel is altered and the frame either raised or lowered
relatively thereto. The drum is provided with a ratchet and pawl which stop the
paying out of the chain and are supposed thereby to hold the wheel in its last
adjustment relative to the frame, but in practice it is found that the wheel can
travel, under the joltings of the machine, slightly back and forth along the racks
by unwinding and rewinding the chain on the axle sheave. This is remedied in the
present instance by placing upon the axle, or forming integral with the sheave
thereon, a disc having an annular series of perforations and connecting the chain
with this disc, after the wheel has been adjusted, by means of a rod or link having
a hook at each end; one of which books is inserted in a perforation in the disc
on that side of the axle opposite the point where the chain cones iu contact with
the sheave, and the other into one of the links of the chain near to the drum upon
which it is wound. The effect of this arrangement is that whenever there is any
tendency of the chain to unwrap from the sheave, the rod will act in opposition
and prevent the sheave from turning so that the wheel will thus be kept in its
position until that is intentionally changed. When a chain belt is employed passing
over sprocket wheels on both the axle and the drum, the hooked rod and perforated
disc will be found nearly or quite as beneficial the rod of course being hooked into
that ply. of the belt reverse to its point of attachment to the disc.

I, JOHN OWDEN O'BRIEN, care of W P. Thompson and Co's Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, Lancashire, Engineer, do
hereby declare the nature of the said invention for "IMPROVEMENTS IN GRAIN
BINDING HARVESTERS" (a communication from abroad by William R. Baker and
Henry E. Pridmore, both of Chicago, Cook County, Illinois, United States,
Engineers) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates firstly,-to the frame of the binding attachment which is,
in the main, of metal, dispensing with the cumbrous wooden beams and timbers
heretofore used to tie its various brackets and bearings together; secondly,-to
a device, hereinafter termed the "table-trip," designed as an improvement upon
one formerly used to prevent choking of the grain in the. binding passage and
start the machine independently of the ordinary trip when such choking occurs;
thirdly, to improvements in the usual finger-trip and its accessory mechanism
enabling it to cooperate with the new table-trip; fourthly, to a slack-lever and
tension which are herein.made to cooperate by a single spring, and the former of
which serves to lock or dog the pinion that carries its controling cam, whenever
the binder is out of action, in order to hold the mechanism steady and in place
until tripped; fifthly, to a cord-book arranged at the end of the cord-guide
heretofore used with the knotter or tying-bill in modern binders, whereby the cord,
after being guided into place for the action of the knotter, is prevented between
the knotter and holder from slipping too low for said knotter; sixthly, to means
for operating the cord-holding disk, consisting in a hooked pitman suitably guided
to engage with a ratchet upon the disk and reciprocated by a revolving shaft
mounted in the holder-frame; seventhly,-to a bundle-carrier which receives and
retains the bound sheaves until sufficient have accumulated to form a shock when it
is thrown by the driver into friction-connection with the gearing of the harvester
and is thereby opened for the discharge of its load;-eightbly, to the sway-bar
for driving the sickle, which sway-bar, instead of being carried transversely through
or beneath the harvester-platform is herein placed beneath the elevator, parallel
with the side of the main-wheel, and connected directly with the heel of the
sickle, also to modifications in the harvester-frame to accommodate it to this
change of location of the sway-bar; ninthly,-to means whereby the main-wheel,
adjusted as usual by a chain wound upon a sheave on its axle, may be held rigidly
in its adjusted position, and tenthly, to means for tightening the platform-apron
whereby said apron may be tightened by a single instrumentality, and may be
adjusted as to its connection with such instrumentality to keep its surface evenly
controlled thereby.
A type of binder manufactured by the McCormick Harvesting Machine Company
during the past season, and well known in this country, may be referred to in
illustration of such of these improvements as are embraced under the first four
heads, although some of their features will be found applicable to machines differing
in structure. In said type the grain was received upon a platform-apron, carried

page_text: up an elevator at the inner end of this apron and discharged into
descending
chute or covered passage-way where it was urged forward wisp-by-wisp or bunch-
by-bunch, by alternating packer-arms, against tripping fingers which closed the
outer side of the chute. A section of the decking in the chute was hinged at the
top and connected with the tripping devices so that in case the grain lodged in
the passage-way before reaching the trip-fingers, it might press upon this section
and thus start the trip.
One of the packing arms operated through a slot in the hinged section, while the
other arm operated through a slot in the stationary part of the decking. The
trip-clutch on a shaft actuated from the harvester was connected with the trip-
fingers and hinged section, or "table-trip" as it is called, so as to be thrown into
engagement with a loose pinion on said shaft by the starting of either or both of
these tripping agencies, and this pinion, when engaged, drove by means of two
intermediate idle wheels," a gear-and-cam-wheel on the binder-shaft, whereby the
knotter, holder and cutter, the binding arm and the support for the outside trip-
fingers were timed and moved. A slack-lever, controlled by a cam on one of these
idle wheels was also employed to take up or give out slack in the cord at proper
intervals.
Referring now to the first five sheets of the drawings,—
Figure 1 is a skeleton side elevation of a binding attachment embodying said
improvements of the first four heads, the wind-board and butt-apron and part of
the frame-work being removed to more clearly expose the operative mechanism.

A represents the post-frame or main bracket, having one arm or sleeve a, over-
hanging the binding table or grain chute and serving as a bearing or support for
the binder-shaft, and a second arm or sleeve a¹ subtending said table or chute and
receiving the rock-shaft which carries the binder-arm. These tubular arms are
united by a post a² strengthened by a vertical flange, or web a³ bored at two
points, a and a to receive stub-axles for the two idle gears in the train com-
municating motion to the binder-shaft, and from the lower or subtanding arm
project inwardly towards the harvester ears or lugs a, a, at an angle to said post
determined by circumstances but here shown as slightly obtuse, the lug a7, being in
other respects, however, a substantial extension of the post, and advisably further
united therewith by integral connection through the just mentioned vertical flange,
as shown. Opposite to these lugs are other lugs a³, a³, in the same plane therewith,
and also integral with the post frame, and these latter, as well as the lug a¹ are
preferably strengthened by webs from the subtending arm and post, formed in the
process of casting.
Bolted to each pair of lugs or ears thus provided, are transverse bars B, B¹, of
cast-metal, malleable iron or steel for instance, which, on the outer or stubble-
side of the arm, have each a bearing b for the reception of a rock-shaft, which
carries the trip-finger, as presently described, and on the inner side are first bent
downward or away from the plane of said ears, and provided with other bearings 61.

from these bearings, rise upward until they reach and saddle a tubular frame-bar G,
such as heretofore us used for like purpose, to which they are secured, by through
bolts, as shown. At their lower or outer ends, just inside the shaft for the tripping
fingers, they also saddle and are similarly secured to a second tubular frame-bar G₁,
extending parallel with the other from front to rear of the binder-frame and,
beyond this last connection and outside of said shaft, the bar B₁, which is the
rearmost and lies alongside the plane of movement of the binder-arm, has a
bracket extension c, in practically, or nearly, the same plane with a like offset or,
bracket c' from the subtending arm or sleeve of the post-frame, these two affording
seats for the chute-decking or binding table. Other brackets c² are bolted to the
frame at suitable points for the same purpose. Both transverse bars have also a
pendent ear c³, inside of and in close proximity to the post-frame, to receive and
support the tripping rock-shaft, but these ears may, if desired, be formed integral
with said post-frame.
At the junction of the front transverse bar with the upper tubular bar, and
preferably by the same bolt uniting the two, is secured one end of a brace-bar D,
of strap-iron or other suitable metal, which extends from this point to the upper
stub-axle on the post-frame-web, thus tying. the post-frame firmly.
The tubular frame-bars are further united in rear of the binder-arm, by two
wooden cross-pieces or timbers E, E', the inner one of which supports a bearing
bracket e, for the rear end of the packer-shaft, this, in machines of the present
type being the one continuously driven from the harvester and on which the trip-
clutch is mounted. Instead of wood, metal can be readily used in place of these
timbers, but as the metal frame-work already provided gives great strength and
rigidity to the whole construction they have very little strain or labor to support
and light wooden bars, such as shown, are consequently quite sufficient in their
position.
Brackets F, bolted to the outer elevator-struts near their head, receive in
suitable seats a tubular supporting bar F', which is firmly secured in place, and
guides or keepers f, from this bar embrace the upper tubular frame-bar and permit
it to slide longitudinally as demanded by the adjustment of the binder. The
lower tubular frame-bar rests upon properly grooved anti-friction rollers g,
borne at the upper end of standards G, from the end sill G', of the harvester frame.
Yokes or keepers g', projecting from these standards above, the rollers, confine the
bar against lateral displacement and metal rods g², from the sill, hooked in and
clamped to ears from the standards which are themselves of metal, serve to brace
the latter.
Proceeding now to the description of the improvements in the binding apparatus
proper, This as heretofore may be driven by a crank packer-shaft H, journaled in
the frame as already described, and having a tripping-clutch h, of well known
construction. A loose pinion ¹ upon the end of this shaft, locked thereto whenever
the clutch is tripped, communicates motion through the idle gears h2, h3, mounted
upon the stub-axles from the post-frame-web, as stated, to the gear-and-cam-
wheel H¹, on the binder-shaft 4, and by this wheel all the positive movements of
the binding devices are produced.
A trip-shaft I, is mounted in the bearings provided therefor in the transverse
frame-bars and when rocked in the suitable direction, operates, by means of a
crank or lifter at its end, to raise the trip-dog I', against the force of the spring i
by which it is held down, and thereby disengage it from the clutch and permit the
latter to grasp the driving pinion. A shoulder i, upon the. hub. of the dog is
arranged to come against a counter-shoulder 2 from a collar embracing the
binder-arm-shaft 3, which latter forms the pivot for the dog, thus guarding against
the dog falling beyond the point at which it should engage with the clutch. The
spring i, as usual, is coiled about a curved rod rising from the actuating crank i,^
on the end of the binder-arm-shaft.

page_text: Instead of the hinged wooden table-section formerly adopted, a narrow forked or
slotted metal frame K, is employed, the two side-bars of which extend along the
side of, and within, the slot in the decking for the play of the binder-arm k, and
lie one on each side of the latter as it rises. This frame is hinged to a bracket k¹,
from the upper tubular frame-bar which is practically at the head of said slot, and
extends down therefrom until its lower end, which is for this purpose somewhat
narrowed, reaches and passes between the outside trip fingers, being free to play up
and down therebetween. It rests upon an arm k², from a casting affixed to the
rear end of the trip-shaft, so that when depressed by the accumulation or
obstruction of grain above it, it will force down said arın and rock the shaft to
disengage the trip-dog. On the binder-shaft, which, it will be understood, subtends
the grain-table or deck, or on the hub of the binder-arm, is a cam or lug ³, in such
position that as the arm rises and approaches the end of its ascent, in the binding
oporation following the engagement of the trip-clutch, it strikes against the under
surface of the metal "table-trip" and lifts it to give an additional compression
to the sheaf over that given by the packers and binding cord.
In order to bring about co-operation between the table-trip and the outside
compressing fingers, the casting or sleeve from which the already mentioned trip-
arm² extends inwardly and upwardly until it comes against the underside of the
table-trip to support the latter and respond to its movements, is provided, upon the
opposite side of the trip-shaft, with a second arm k', extending outwardly to one
side of and beneath the pivoted trip-fingers L, where it rests upon a lug 1, from a
heel-extension of one or both, so that as said fingers are pushed back upon their
pivot they will lift this second trip-arm and rock the trip-shaft, while the table-
trip, if itself depressed; will push down the opposite arm, rocking said shaft in the
same direction. Thus the trip-dog will be unlatched from the trip-clutch by the
proper movement of either of these devices under pressure of the grain.
The trip-fingers are bolted to a skeleton block, baving an arched crown with
longitudinal and transverse slots. A tongue 2 from the base of the fingers takes
into the transverse slot or slots, while a clamping bolt 3 passes from said base
through the longitudinal slot, thus by loosening the bolt the fingers may be adjusted
in and out along the block, to diminish or increase the grain receiving space and
consequent size of the gavel. The block, which in this instance forms the above
styled "heel extension" of the fingers, instead of being pivoted upon a supporting
arm hinged to the heel of the binder-arm, and sustained by a link from an under-
lying rock-shaft as heretofore, is mounted directly upon a rock-shaft M, supported
in the outer bearings of the transverse frame-bar and subtending the binding tablė
near the outer edge of the latter, and plays upon said shaft as a pivot. The
links m which control the heels of the packer-arms M', are also pivotally suspended
from this shaft, but the packer-arms themselves are driven in the usual manner by
direct connection with cranks m² on the driving shaft.
Keyed fast to the shaft which carries the trip-fingers, and alongside the supporting
block or heel-piece of said fingers, is a casting N having a lateral pin or lugn,
which takes into a lateral slot n¹, in said heel-piece, and a radially extending arm ²,
link-connected with the tail-board O, of the binding receptacle so that whenever
the shaft is rocked said casting may both swing the trip-fingers back with it and
open the tail-board.
A crank o on the end of the last mentioned rock-shaft is connected with the
gear-and-cam-wheel by an elastic pitman o' and T-head O', similar to the one
formerly used for opening and closing the aforesaid supporting bar, so that when
the binding mechanism starts the shaft will be operated by the action of said
cam-wheel.
As the connection between the tripping fingers and the casting fixed to the rock-
shaft is by slot and pin, said fingers are permitted to swing back on the shaft
under the pressure of the incoming grain a sufficient distance to start the trip,
provided they are previously held in. such position that the pin is normally at the
outer end of the slot. This is accomplished by the trip-arm, or lever from the
.5

page_text: trip-rock-shaft, which is pushed firmly down against the off-setting lug from
the heel of the trip-fingers, whenever the binding operation is finished, by means
of the rod and spring connection between the trip-dog and the crank on the end of
the binder-shaft, or, in other words, as said binder-shaft is in its retrograde
movement to withdraw the binder-arm beneath the table to its position of rest
which movement, as well as the primary advance movement, is caused by the
pitman P, from the gear-and-cam-wheel, it forces the trip-dog against the lifting
finger upon the end of the trip-shaft thus rocking the latter and carrying the
outside trip-arm or lever against said lug, whereby the trip-fingers are swung
inward as far as the slot-and-pin .connection with their supporting shaft permits
them to go, and with precisely the same force which the accumulating gavel must
overcome in order to again start the machine.
The slack-leyer has heretofore been pivoted on the front board of the binder,
sometimes called the wind-board, and its heel provided with a roller which travelled
upon a cam on one of the idle wheels driven from the trip-pinion, so that its front
end would be raised or depressed at proper intervals to take up or give out slack
in the cord which run through an eye in the free end.
This slack lever Q; it is now proposed to provide with a tension-finger q, pivoted
to said lever and resting upon the cord running through it, the lever, for this
purpose having advisably two eyes q', at the free or effective end; between which
eyes the end of the tension-finger rests and pressês upon the cord. A casting R is
secured to the front metallic frame-bar by slots and bolts so that it may be adjusted
slightly there along if found necessary, and from beneath. this casting' depends a
hanger r, having a guide-eye or eyes for the cord, in line with the eye or eyes in
the end of the slack-lever, while above rises a vertical ear 1, bearing a stub-pivot ²
for the slack-lever and a series of pins 7 arranged concentrically with said pivot.
A spring, coiled about this pivot-spindle has one arm projecting up to be sprung
in between any two of the pins, to increase or decrease its stress and the other arm
arranged to press upon the tension-finger beyond its pivotal connection 5, with the
slack-lever thus at once forcing the tension-finger down upon the lever and, through
said finger, exerting pressure thereon and holding its heel in constant contact with
its controlling cam.
Said cam S, is mounted upon the side of the front idle-wheel h', or that one in
engagement with the trip-pinion on the driving shaft, and, while its general outline
is the same as heretofore employed, it now has at that point where the roller s, on
the heel of the heel of the slack-lever, comes at the moment the hinder is thrown
out of operation, a notch 8¹ of substantially the form shown, so that said heel,
pressed forcibly up by the action of the spring upon the lever, shall rise into the
notch to hold the idle-wheel out of motion and steady the binder-mechanism.
Of course it is not broadly novel to lock binding mechanism when out of action,
since brakes and other stops have been applied to various wheels therein, and
notably to the gear-and-cam-wheel, but in the present instance, it will be observed,
the locking device is applied to the idle-wheel next to the driving pinion, and is
furnished by the slack-lever and its cam, thus placing double functions upon these
instrumentalities.
Passing now to the fifth head of invention:-
In grain-binding machines of the before mentioned type, there has been employed
in connection with the knotter or tying-bill, and with the cord-holder, an inter-
mediate cord-guide bolted to the supporting bracket or frame, in which the knotter
is carried and curved downward and inward so that as the binder-arm approaches
the holder, to deliver the strand or cord which it carries, this strand shall be
deflected, if out of its proper position, and carried to a point where it over-lies the
jaws of the knotter and be prevented from lateral displacement thereafter. In
'practice, however, it has been found that one or both strands would occasionally
slip past the end of the guide and fall too low for the action of the knotter,
or sometimes be carried past said end by the onward rotation of the holder-disk.
It is, therefore, now proposed to provide the end of said cord-guide with a recurved

page_text: hook or finger thereby forming a notch within which both strands, after being
in succession guided to their position over the knotting jaws, will rest and be
prevented from escaping.
<<
In the sixth sheet of the drawings-
Figure 18 is a front elevation of a binding head embodying this improvement.
Figure 19 is a top plan view thereof.
Figure 20 a detached view of the cord-guide.
A is the stock of the binding head, and B, a knotter, of the type known as
tying-bills," supported therein. The axis of this knotter, in the present instance,
is shown as horizontal, or substantially so; but it will be obvious from the ensuing
description that it may assume any desired inclination provided the relation of the
other parts thereto is maintained.
C and D, are cams which control the pivoted jaw of the knotter, the latter cam
operating to open it when it has partially completed a revolution, to admit the ends
crossed over the loop around it, and the former to sharply close it upon these .
ends as the revolution is finished.
At a proper distance beneath the jaws is a holder E, composed in this instance
of a rotating notched disk e, which takes into or over a spring-pressed shoe e¹, and
is intermittingly moved to force the cord into said shoe, and thereby clamp it. It
is desirable that the holder should yield or move up toward the knotter during the
tying operation in order to render up slack. The length of the. ends stretched
between knotter and holder at the moment of initial movement of the former, will, .
in such case, often be so great as to cause a very considerable liability to escapo
from the action of said knotter when it once commenced its revolution, since its
surfaces are necessarily to some extent cam-shaped. Moreover, whether the holder.
is movable or stationary, this tendency usually to some extent exists as there must
be a certain space at all times between it and the knotter or band-securing device.
With a movable holder also, which must be hinged at a distance from the knotter,
the cord-strands held must partake of the arc-movement at the clamping end of the
holder and are pushed out away from their proper position as the latter rises. These
defects have heretofore been partially obviated by the employment of the curved
deflecting or guiding arm F, which was arranged between the knotter and holder,
being attached firmly to the top or frame by a bolt or other connection and
directed, on that side of the cord-receiving space opposed to the knotter, inward
and downward and underneath the latter, and then laterally a short distance
outward as shown. This serves to guide or lead the band-ends of the cord into
proper position for the initial action of the knotter and also to resist and correct the
sidewise thrust, push or displacement given them by said knotter as they slip over
its crown to form the cross or twist in the loop.
As formerly constructed this arm was open at its end and the cord sometimes
slipped past it, or else was carried past it by the revolution of the holding disc, or
by the outward thrust of the holder as it rose, so that when the knotter-jaws
opened to grasp the end of the strands and complete the knot the strands were
occasionally out of their proper position and would not enter between the jaws and
therefore the band was not tied and the sheaf escaped unbound.
These defects are herein overcome by recurving or turning backward the end of
the guide-arm without, of course, making its effective length any shorter, or
materially shorter, so as to form a finger "f" between which finger and the main.
portion of the arm the strands are caught when they have reached their proper
position, and beyond which they cannot slip. They will therefore, be absolutely
retained in position and certainly grasped in the jaws of the knotter as it is
completing its revolution.
Upon the frame is mounted another guide-arm G, having a guide-way g, which,
when the binding-arm is laying the cord to form the band, rests in front of the
knotter and co-operates with the other guide in positioning the cord. In order
that the arm G, may subserve other functions it is pivoted upon the stock and
controlled at its heel-end in such manner that after the knot is formed it is swung

page_text: aside and bears upon the band between the knotter and the sheaf to strip it forcibly
from said knotter. A knife g¹, is also attached to this guiding and stripping arm G,
in such position that as it starts on its side-wise movement to strip the knot said
knife is brought against the strands stretched between the other cord-guide and the
holder and severs them.
In the binding head chosen for illustration, the inner or under jaw of the knotter
is the pivoted one.
The binding-arm delivers the cord to the holder through the
space or opening h, behind both cord-guides, and at this time the knotter is
stationary with its jaws in a substantially horizontal position transverse to this
opening. When both ends of the cord have been delivered to the holder the disk e,
of the latter moves one notch in the direction of the arrow, carrying them into the
shoe and firmly clamping them. This movement takes the ends stretched between
the knotter and holder along the curved edge of the guide F, and lays them in the
notch formed by the guide-arm and its book, in which position they are stretched
against and beneath the chin of the knotter which then commences to rotate. By
the time the knotter has entered the third quarter of its revolution, the loop is
formed and the ends leading to the holder are crossed thereupon. The inner jaw
now opens and passes on one side of the two strands, while the fixed outer jaw
passes on the other. Just as the revolution is completed the jaws come together
under the force of the cain C and seize the strands. The stripper-arm is then
actuated to sever these strands between the holder and guide-arm, and draw the
loop forcibly from the knotter, whereby it is tightened upon the ends held between
the jaws of the latter and finally these ends are wrenched from the knotter and the
sheaf is discharged, completing the binding operation.
The sixth head of invention relates to the mechanism by which the end of the
binding cord is grasped and held when delivered by the binding-arm, and more
particularly to the now common rotary disk-holder. This, as just above stated, is
generally mounted in a swinging frame and so controlled that it is made to yield
towards the knotter as slack is demanded in the tying operation, but is forced away
therefrom immediately after the knot is finished.
In this class of holders, the rotary disk by which the cord is grasped and forced
against the clamping shoe, is intermittently impelled at suitable intervals by means
of a ratchet on said disk and a pawl engaging with said ratchet, which pawl is
sometimes mounted on a bell-crank-lever, and, in nearly all modern machines,
driven by means of a cam-track or ledge in, or upon, the face of a gear-and-cam-
wheel mounted on the binder-shaft.
Aside from the objectionably cumbrous nature of such apparatus, and the
relatively large amount of friction involved, it has been found that the rough usage
to which they are subjected. in practice, the gritty dust from the field, and other
causes result in a rapid wearing away of the cam-track, the ratchet-teeth, the pawl,
and the joints of the intermediate mechanism so that after a little while the holder
fails to work properly, and the parts have to be replaced."
Such defects as the foregoing it is proposed to overcome by making the point or
nose of the pawl itself adjustable as to its distance from the immediate actuating
mechanism either by constructing said pawl in sections, one movable longitudinally
of the other, or by suitably connecting it with its carrying arm or block, so that
while the stroke remains always the same, said point may be set nearer to or
further from the ratchet-teeth with which it is to engage, as demanded by circum-
stances; and for the purpose of adapting such adjustable pawl to the above
mentioned swinging-holder-frame, said frame is pivoted upon a revolving shaft
intermittently turned by a gear-section on a wheel on the binder-shaft, and held
at rest in the intervals between its movements by a delay surface on said wheel
matching with a shoe upon the pivot-shaft pinion, and upon a wrist-pin from
a short crank at the outer end of this shaft is arranged a sleeve having a lateral
árm or lug to which arm the pawl is hinged with its free end properly guided near
to the ratchet beneath the holder-disk, whereby the revolution of the wrist-pin as
the pivot-shaft turns reciprocates the pawl back and forth and brings it into

page_text: engagement with the ratchet-teeth of the holder-disk, or causes it to ride over their
backs to take a fresh grasp. The cam which controls the times of rise and fall of
the holder-frame is also for convenience and compactness placed or formed upon the
side of the delay-wheel which drives the pinion of the pivot-shaft.

and ultimately to the holder-disk.

disk.
A is the binder-shaft overhanging the grain receptacle and driven by the gear-
and-cam-wheel at the front thereof, as recited in connection with the foregoing
description of the frame. B is a portion of the supporting bracket or bracket-
casting and rear bearing of this shaft, and C is one of the ejector or discharge-
fingers commonly mounted upon and turned by said shaft. These parts will not.
necessarily differ from those now in use and already described, neither is it
essential to the invention that they should identically correspond therewith.
At the rear end of the binder-shaft, inside of the ejector-finger, is a wheel D,
having a peripheral section of gear-teeth d, and a delay-track d', and also upon its
face a cam-ledge d², of practically the outline and relative position shown, for the
purpose hereinafter stated. Supported in a bearing or bearings, in the bracket-
casting opposite the lower inner quadrant of the wheel is a short, shaft E provided
with a piuion e and a delay-shoe e¹, which pinion meshes with, and is of such size
as to be given one revolution by, the gear-section, while its delay-shoe locks with
the delay-track on said wheel in the intervals between the revolutions and prevents
motion. The end of the shaft away from the pinion and about the center of the
holder-frame is cranked and has a wrist-pin e², whereby motion is to be inter-
mediately cominunicated to the holder-disk.
This short shaft, hereafter called the "holder-shaft," in distinction to the binder-
shaft, affords one of the journals f for the holder-frame f¹, the other journal ƒ³,
being located upon the bracket-casting in axial prolongation with the shaft.
A heel-projection f³, rises from the holder-frame alongside of the wheel on the
binder-shaft and a roller f, from this projection bears against the above mentioned
cam-track or ledge d³, on the face of said wheel whereby the frame will be pressed
down and held down for the proper interval and then allowed to rise to yield slack
in the binding operation, pivoting in this movement upon the axis of the holder-
shaft which can therefore actuate its mechanism irrespective of the displacement.
In the usual position on the holder-frame is journaled the notched holder-disk G,
held against retrogression by the click g, and saddled at one side by the spring-
pressed clamping shoe g¹, such as has heretofore been known. A ratchet wheel g²,
is secured beneath the holder-disk, as customary, whereby it is to be driven.
Upon the wrist-pin is loosely mounted a block or sleeve H, having a lateral arm
or lug h, to the end of which the heel of the pawl or dog H¹, is pivoted. A spring h¹,
is rivetted or otherwise secured to the lateral arm, or to the sleeve, in position to
press at its free end against the back of the dog and force it towards the ratchet
beneath the holder-disk, and said dog is guided and prevented from circling about
the wrist-pin on one side by means of a smooth or planed way h², upon the frame-
arm which extends beneath and supports the disk and ratchet, and on the other.

page_text: either by the over-crowning disk, or by the click which is so arranged as to bridge
or saddle it. Undue pivotal play is also guarded against in one direction by the
lug, rising from the frame-arm behind the dog, and in the other of course by the
ratchet.
The point of the dog is preferably hooked so as to catch into and pull upon the
ratchet as it is drawn back by the revolution of the wrist-pin, but it may be
pointed to push upon the ratchet, the teeth of the latter being correspondingly
reversed.
In order to take up or compensate for wear either the arm to which the dog is
pivoted will be made in two sections, one adjustable lengthwise of the other, or
else the dog itself will be bi-membral and extensible. The latter is the most
convenient resort, and accordingly is chosen for illustration, being the heel-section
pivoted to the arm, and at its other end ribbed or serrated on one face, and, the
nose-section, correspondingly ribbed or serrated on the surface intended to, come
in contact with the roughened end of the heel-section, the connection between
the two being made by a slot k and clamping bolt or screw k³, the former of which
is shown as formed through the heel-section but may be in either section. This is
sufficient to permit any reasonable range of adjustment. Other adjusting devices
may be employed, but for the present construction the one described is the simplest
and most durable.
For practical use the gear-section and delay-surface on the periphery of the
wheel upon the binder-shaft, and the cam upon its face, will be relatively so
arranged and timed with reference to each other, and to the parts which they
immediately actuate, that, in the operation of the device, the holder-disk will
move to clamp or grasp the second end of the band having previously grasped the
first, before the knotter commences its revolution and consequently before any
slack is demanded and while the holder-frame is stationary. But this clamping of
the second end, or in other words, the stopping of the disk, may not be entirely.
complete until the knotter has nearly or quite finished its movement. The holder-
frame, which, until the proper moment is held down by the circular or concentric
peripheral reach of the cam acting upon its heel-extension, will be released by the
attaining of the cut-away portion at the time the knotter begins its revolution, and
allowed to rise as slack is required, either by the stress of the cord in opposition to
its own gravity, or else at a rate determined by the outline of the cam at this
point; but in the instance shown its gravity alone will, within' suitable limits, be
opposed to the cord.
Now under the seventh head:-
In order to save labor to the shockers in collecting and assembling individual
sheaves discharged from the binder after each distinct binding operation, receptacles
or bundle carriers, have, of late years, been attached to the machine to receive and
carry the sheaves as they drop fully bound, until a sufficient number have
accumulated to form a shock, when the receptacle is opened and all deposited on
the ground in a lump. Usually the entire labor of opening the receptacle has
fallen upon the driver or attendant, unduly taxing his attention and strength.
The improvement in this respect has for its object to accomplish said action by a
friction connection with the harvester gearing readily thrown into operation by the
driver.
In sheets 8 and 9 of the drawings-
Figure 28 is a rear elevation of so much of a harvester and binding table in
connection with said improvement as is necessary to an explanation thereof.
Figure 29 is an elevation from the stubble end of the machine.
Figure 30 is an enlarged detail of the friction gearing and certain accessories as
shown in the previous figures.
Figure 31 is a vertical longitudinal section.
Figure 32 is an end elevation.

Figure 34 a detail thereof.

page_text: A represents the elevator-frame of usual shape, B, the driver's seat mounted on
a plank inside the elevator, or where otherwise required by the exigencies of
the machine, and D, is the binding table. The automatic binding mechanism
customarily employed in connection with such table is not shown, but it will be
understood, that the operation of the improvement has no relation to any
particular form or type of binder or binding table, and that the type already
described may be used as an exponent of the whole class.
Two supporting frames formed of crossed bars E E¹, are bolted, one to the front
rail and sill, and the other to the rear rail and sill, of the elevator-frame. To the
lower bars of these two frames immediately beneath the tail board of the binding
receptacle, is secured a board F, forming the inner member of the bundle-receptacle.
This board is attached by means of pivots or hinges, which permit it to fall to a
sloping position, but hold it rigidly against further descent.
The bundle-carrier proper, C, is composed of an open frame-work of bars and
slats secured together by cross-pieces or ties, which will advisably be of metal.
It is hung from the upper bars of the cross-pieces by means of bails g, g', which
take into notches in the outer ends of said bars and are secured therein by hooks
or latches, or otherwise. From the outer side of the swinging carrier rises a long
lever-arm H, the top of which is brought substantially in line with the rear of the
elevator and almost on a level with the head of the elevator at that point. By
means of this lever the carrier can be swung back upon its supports, but when the
lever is released, said carrier will gravitate until its bottom closes against the above
mentioned hinged board forming a close receptacle.
The pinion I, on the rear gudgeon of the upper elevator-roller, drives an idler i,
which communicates motion to a spur-and-friction-gear 2 mounted loosely upon a
short spindle supported in brackets on the top bar of the elevator-frame. On the
same spindle and alongside of the friction-gear is loosely mounted a drum K,
having a limited motion longitudinally of the spindle. On the spindle at the end
away from the pinion, is also mounted a thimble K¹ which after encircling the
spindle close to the hub of the friction-drum, bridges the adjacent bracket-standard
and caps, and is steadied by the protruding end of the spindle. Between the
drum-hub and the thimble a washer may be inserted. The thimble does not fit
close to each side of the standard which it bridges, but is allowed a limited play
longitudinally of the spindle, notwithstanding the bridge. Against the cap on this
thimble, presses one end of a crank-lever k, pivoted in a sleeve k¹, from the
bracket supporting the drum and depending diagonally along the inner rear strut
of the elevator to a position near the standard of the driver's seat, where its lower
end is connected by a strap or link with the treadle L, convenient for operation by
the driver. Thus when the driver presses upon the treadle, or with his heel presses
upon the strap between the treadle and lever, the friction-drum will be caused to
engage with its corresponding gear which is continually driven from the elevator-
roll, and the drum will be driven by the friction-grip ensuing between the two.
As a modification the thimble may be omitted and the end of the lever caused
to yoke with a groove or recess in the hub of the drum, as indicated in Fig. 3. In
such case the lever may be straight and the position and character of its pivot
somewhat altered as shown..
To the upper end of the lever on the bundle-carrier is attached one end of a rope
or cord M, the other end being wound upon the drum, so that when the drum is
engaged with its friction-gear, and revolving, this cord will be taken in and the
lever operated to open the carrier.
Near to the druin is placed a guide or check-yoke m, through which the cord
passes, and upon the cord is adjusted a block m', so that when sufficient of the cord
has been wound up upon the drum to open the bundle-carrier to its full extent,
this block comes against the stop or check-yoke and prevents a further length
being wound, as the friction-grip between the drum and gear will be overcome
sufficiently to permit the gear. to revolve while the drum remains stationary,
holding the cord, and thereby the carrier open until all the sheaves have been

page_text: •
discharged when the driver, releasing his pressure on the foot treadle or strap, will
release the drum from further frictional contact with the gear and the gravity of
the carrier will unwind the cord and close the receptacle.
Instead of the direct connection of the rope or cord with the top of the lever, a
sheave may be mounted on said lever and, the rope led from the drum over the
sheave and then returned and its free end fastened to the drum-bracket or to an
eye thereon, or near thereto, thus decreasing the labor on the drum and opening
the carrier with less violence.
The cross-frames which support the swinging carrier, are adopted as a convenience;
and because they afford a simple, strong, and efficient means of attaching and
suspending the carrier from the ordinary harvester-frame without any structural
changes in that frame. It is not intended however, to limit to these precise means
for the support of the carrier, although they are considered the simplest and inost
efficient. Nor is it intended to limit to a carrier of the precise shape shown, so far
as the improvement relates to operating the bundle-carrier by means of a friction-
connection with the harvester gearing, nor to the specific friction connection
described as there are several well known forms of friction-clutch,
Sway bars, as stated under the eighth caption, have been formerly carried
through or beneath the harvester-platform and connected with the sickle at the
middle of the length of said sickle. This either involved cutting through and
weakening the front and rear sills for the admission of the sway-bar to the cutter-
bar, or required the sway-bar at its forward end to make connection with the
sickle by a bend or crank which was easily broken by the heavy labor imposed
upon it. They have also been placed parallel with and close to the divider-board,
which involved an unnecessarily long and much exposed pitman. Instead of
either of these arrangements in the present invention, the sway-bar is carried
beneath the elevator alongside of the main-wheel and between said wheel and the
ascending side of the elevator-frame, and, being pivoted nearly opposite the axle
of the main wheel, is driven by a pitman from a crank-shaft on the outer side of
said wheel at the rear of the machine. The heel of the cutter-bar or sickle is
extended so as to directly connect with the front end of the sway-bar.
Preferably the sway bar is inclined, bringing its rear end just above the rear sill.
of the elevator-frame while the front end extends beneath the front sill or timber
of the platform-frame. The pivot of the sway-bar is therefore made slightly
compensatory, as well for this reason, as because the rear end of the sway-bar
where it connects with the pitman is intended to be suspended by a pendulum
from the elevator-frame to avoid the thumping which would otherwise ensue from
the action of the pitman.
•
Instead of constructing this sway-bar of wood, as usual, it is made of two bars
of steel, bent and relatively inverted to form trusses, braced at the center by a
king-block or stretcher of malleable iron which affords the pivot-journal, and
having their ends connected by other blocks or caps, one of which serves to unite
the sway-bar with the heel of the sickle and the other for the attachment of the
pitman and pendulum. A very light and strong sway-bar is thus secured.
Referring to the tenth sheet of drawings-
Fig. 35, is a plan view of the sway-bar constructed in accordance with this
improvement.
Fig. 36 a side elevation thereof..
Fig. 37 a top plan view of a harvester, with the sway-bar arranged according
to said improvement a portion of the clevator-frame being removed to expose said
bar and the gearing by which it is driven.
Fig. 38 a rear and Fig. 39 a front elevation of said harvester, and
Fig. 40 is a transverse section through the harvester between the main wheel
and the sway-bar, as indicated by a correspondingly numbered line in one of the
preceding figures.
A is the front, and B the rear sill of the harvester. These, as already stated,
have usually been mortised or slotted midway of the length of the platform to

page_text: receive the sway-bar extending through them from rear to front and there
connected with the cutter-bar. But herein they are made of uniform thickness
and strength throughout their length.
C is the main wheel mounted in suitable standards in the lateral bars of the
wheel-frame beneath the elevator; and, of course, although not so shown, having
provisions for its up and down adjustment to vary the height of the harvester.
The front platform-sill extends to near the main wheel and is secured inside the
ascending portion of the elevator to two cross-timbers, the first of which D, forms
the inner elevator-sill, and the second D1, the inner lateral bar of the wheel-frame.
The front sill of the elevator-frame enters at its inner end between the platform-sill
and the inner elevator-sill, and is secured to that by the saine bolt which serves to
unite the two, as will presently appear. From this junction with said sills it
extends diagonally outward and forward beyond the main wheel where it is bolted
to and supports the front end of the outside elevator-sill D², which also forms the
outer lateral bar of the wheel-frame.
The rear platform-sill extends beneath the two inner timbers D and D¹, and
terminates with the latter, supporting the rear elevator-sill by a lamp-joint there-
with beneath these two timbers, and being united with said sill by bolts passing
respectively through the timbers and the sills, and the rear elevator-sill supports in
the usual manner the outside sill of the frame.
The angle-iron finger-bar E is carried the whole length of the front platform-sill
and its lower web secured thereto at frequent intervals, and is bolted by its upper
web at two points to the oblique front-sill of the elevator-fraine, at the inner point
by a bolt passing through the inside sill of said frame, as well as the oblique sill,
and thus serving to unite the two to the platform-sill, and at the outer point by a
second bolt passing through the inner lateral bar of the wheel-frame, and in like
manner uniting the three sills at this point.
+
By this means an unusually strong connection is made between the front
platform-sill and the elevator-frame, and the platform-sill itself is greatly
strengthened. The extended angle-iron may also be beneficially used where the
front elevator-sill is not obliquely set.
If the sway-bar should be allowed to occupy its usual position or if the sickle
should be driven by a crank and pitman at the front of the machine, the rear
platform and elevator-sills and the front platform-sill with its finger-bar, and
oblique sill of the main frame may lie in contact at the point where they are
united and the advantage of extending the angle-iron and uniting the frame-work
in the manner just described will still be secured. But for the purpose of bringing
the sway-bar within the space enclosed between the ascending side of the elevator
and the main-wheel it has been found advisable to separate them at their point of
union by spacing blocks a, which lift the front and rear elevator-sills from the front
and rear platform-sills and the finger-bar on the former, and the fastening bolts
will therefore pass through these spacing blocks in uniting the parts together.
In order to support the sway-bar in this new position the timbers D and D¹, are
connected at about the middle of their length by a metal bridge F, bolted to their
under sides and having a pivot-pin f, at or near its center which supports and
forms a fulcrum for said sway-bar, the latter being connected at its front end with
the heel of the cutter-bar or sickle, for that purpose lengthened, or with a suitable
head f¹, rigidly affixed to said heel, and at its rear and extending outside of the
rear elevator-sill where it is ball-jointed to a pitman G reciprocated by a crank g,
on a shaft gl, outside of and parallel with, and driven by, the main wheel.
A sprocket-wheel g², or other suitable gear on this shaft enables it to impart motion
to other parts of the harvester and to the binder, as well as to the sway-bar, in the
usual manner.
As already intimated, the sway-bar, although it might be laid horizontally and
project at the rear end through the opening left between the spacing blocks which
lie between the rear platform-sill and the rear elevator-sill and serve to lift the
latter into the same plane with the oblique front sill, is advisably inclined so as to

page_text: lift it above said rear elevator-sill. This is mainly to bring it in line with the
driving shaft supported above the latter sill, and thus avoid as much as possible
any angular thrust of the pitman. To further ease the action of the pitman upon
said bar, its rear end is supported by a pendulum I, pivoted at i to the rear inner
elevator-strut, or other feasible support. This relieves the thumping ordinarily
attendant upon the action of the pitman, and more noticeable where it is so greatly
shortened as here.
•
The are described by the pitman will cause a scarcely appreciable deflection of
the sway-bar, but to compensate for this, as well as for its inclined position, it may
be allowed a little slip longitudinally of its pivot, or other provision adopted
whereby its play at the front end may coincide with the right line travelled by the
heel of the cutter-bar. However, when the elasticity of the latter is sufficient,
such pivotal compensation may be dispensed with.
The sway-bar K, constituting an additional feature of this improvement, is com-
posed of two light steel bars k, bent and relatively inverted, as shown, to form
trusses. A king-block L of malleable iron or other suitable metal, spaces them at
their center and affords the pivot-journal 7, while at their converging ends they
enter seats in, and are bolted to, other blocks, of which the block L at the front end
has a socket m for the reception of a stud m³, from the heel of the cutter-bar, or
else itself has a stud or knob to enter a socket in said hook, while the block N, at
the rear, has a globular or other appropriate head n to afford a joint with the
pitman, and whenever the pendulum is used-a lug o with an eye for the reception
of the hooked-lower end of said pendulum. The use of the sway-bar as thus
constructed, is, of course, not limited to its arrangement beneath the elevator.
Coming here to the ninth caption :-
_
°.
Of late years the axle supporting the main wheel has been provided at each end
with fixed pinions, which engage with and turn, upon segment-racks formed in
upright bridle standards secured to the lateral bars of the wheel-frame. A sheave
pinned to the axle receives one end of a chain the other end of which is wound
upon a drum on one of the longitudinal sills of the harvester-frame, usually the
rear sill, and when this drum is turned in one direction or the other, the axle is
revolved either by the stress brought upon the chain as it is taken in or by the
pressure of the harvester-frame, as said chain is let out, so that the position of the
wheel is altered and the frame either raised or lowered relatively thereto.
In practice this mechanism, while serving its purpose well fails to hold the wheel
rigidly in position under all the contingencies of the field, and it will sometimes
travel a little distance up or down the racks under the joltings experienced on
uneven ground. To remedy this locking dogs have been used closing into the rack
and preventing the frame from sinking. But these afforded a rigid lock in one
direction only and permitted the frame to move in the other.
In this invention it is proposed to place upon the axle, or to form integral with
the sheave. thereon, a disc with a series of circumferential perforations, and connect
the chain with this disc by means of a rod or link hooked at each end, one of these
hooks taking into a perforation on the disc and the other into one of the chain-
links, thus preventing the chain from unwinding or winding up.
In the eleventh sheet of the drawings:
Fig. 41 is a side elevation of a main wheel and adjusting devices embodying said
improvement, with so much of the wheels frame shown as is necessary to an
understanding thereof, and
Fig. 42 is a top plan view of the same.
A, is the rear sill of the harvester and A¹ the front sill. B and B' are the lateral
timbers of the wheel-frame, and C is the main wheel running loosely on its axle c,
and carrying the usual gear D, by which the prime-pinion d is driven and motion
communicated to the harvester.
Bolted fast to the lateral timbers are segment rack-standards E, which receive
the pinions e riveted to the ends of the axle and support said axle thereby.
14

page_text: A sheave F, is mounted upon the axle, to turn therewith, the main wheel and one
of the rack-standards, advisably the outer one. This sheave may be formed
independently of the pinion at that end of the axle, but is shown herein as cast
integral with said pinion, and this is deemed the preferable mode, as a single rivet
will hold both to the axle, and time and labor in assembling the parts are thus
avoided. The sheave receives one end of a chain G, which is wrapped about it in
such manner that as the harvester-frame descends upon the wheel the chain will be
wound up upon the sheave and as the chain is forcibly unwound it will roll the
axle in such direction that the frame will be lifted. The other end of the chain is
wound upon a drum H, supported upon the rear sill, and a ratchet-lever h, or other
suitable device, serves to turn this drum to wind in or let out the chain. A pawl h¹
taking into a ratchet-disk upon the drum locks it against the stress of the chain so
as to prevent this from unwinding.
Between the drum and the sheave there is necessarily a considerable length of
chain which will afford more or less slack so that the adjustment is never entirely
rigid, and beside this, as before explained, the chain can unwind from the sheave,.
unless some locking device distinct from the pawl upon the drum is employed?
To prevent this unwinding, or accidental winding up, a disk I, is placed upon the
axle, said disk being cast for convenience and economy, in one piece with the
sheave, and with the pinion at the end of the axle.
This disk has a series of circumferential perforations i, arranged near together
and adapted to receive a hook at one end of the rod K, which at the other end has
a second hook, so shaped and arranged, that it may be caught into one of the
chain-links.
The hooked rod should be of sufficient length to extend from the sheave nearly
to the drum and be hooked into the chain close thereto, so that there shall be
practically no slack length of the chain between the drum and rod.
The effect of this arrangement is that whenever there is any tendency of the
chain to unwrap from the sheave, the rod, which is hooked into that side of the
sheave opposite where the chain leaves it, will act in opposition and prevent
the sheave from turning.
Although this improvement has been described in connection with the form of
adjusting chain ordinarily used, that is, a chain having one wound upon the sheave
and the other upon the drum, it is evident that the hooked rod or link can be
employed quite as efficaciously where sprocket wheels are substituted for sheave
and drum and a chain-belt thrown over the two.
Now as to the tenth head of invention, the object had in view is to tighten the
canvas aprons of the harvester, and of other machines where endless carrier-aprons
are employed in a similar manner, and particularly for tightening the platform-
apron used in nearly all harvesting and binding machines nowadays. And its
general mode of employment will be sufficiently understood by a description in
connection with such platform-apron.
In the drawings, referring to sheet 12:
Fig. 43 is an elevation from the divider or stubble end of a harvester platform
embodying my invention.

page_text: .
A represents the platform-apron and B the grain-board to which is connected the
outside divider C, in the usual manner. The front and rear sills are cut down at
their outer ends to receive longitudinally slotted sliding bars D, having grooves or
ways d on each side of the slot, and boxes or bearings d, at their ends for the
gudgeons of the apron-drum, which boxes or bearings are depressed below the ends
of the bars to bring the drum in its proper relation to the upper surface of the sills.
Outside of the journals and playing through apertures in the grain-board are
hooked arms d, integral with the sliding bars and boxes, one arm to each bar, and
advisably arranged in such manner that the arm of each bar projects from the
outer.end of the box or bearing.
Guide-clips E, having tongues e, which enter through the longitudinal slot in the
bars and rest upon the exposed surface of the sill beneath, and ribs or ways' e¹,
which enter the grooves in said bars, serve to hold the bars upon the sills and are
made to abut against the shoulder where the sill is cut away so as to give a flush
surface therewith to properly support the edge of the apron. At their sides the
bars themselves rise flush with the surface of the clips so that when extended. they
may.to an efficient degree form a continuation of such supporting surface.
While this particular form of clip and bar is considered the best, any other
arrangement that will hold the sliding bar parallel with the sill and brace it against
lateral strain may be employed and is within the scope of the invention..
The hooks upon the sliding boxes are intended to receive loops formed in the
ends of wire cords, or ropes F, F1, of which the cord from the front box is led over
a horizontal sheave or guide-pulley G, mounted in a bracket bolted to standard or
upright post, g, supporting the outside divider, or divider board and from thence
passes to the rear outside corner of the platform, while the cord from the box upon
the rear bar is stretched directly to this outside corner.
Upon the grain-board or end-sill, or any other suitable support at said corner, is
a bracket-casting H, practically in line with the rear sliding bar and the journal-box
or bearing which it. carries.
Two sheaves or pulleys I, I', the first of which has an enlarged disk i, with a
segment rack ¹, on its periphery, and is cupped or recessed on the exposed face of
said disc and milled or radially serrated at the bottom of the cup, and the second
of which is provided with a correspondingly milled disc 2, adapted to sit in the
cup, are arranged within the bracket. One of the sheaves, herein shown as the
sheave I¹, has a journal hub i³, entering a bearing in said bracket, and provided with
a screw-threaded bore, while the other sheave is smoothly bored in line therewith
and receives a bolt K; passed through the opposite bearing in the bracket and
enlarged at its shank to form a journal k within said bearing and a shoulder to
brace against the side of the sheave.
The end of this bolt is screw-threaded to engage with the threads in the above
mentioned hub, whereby the two pulleys or sheaves can be clamped together in any
desired circumferential adjustment.
A pawl or dog L, is pivoted upon the bracket, as at l, so as to take into the
ratchet-segment upon the winch thus formed and hold it against the strain of the
apron, and a thumb-piece on this pawl enables it to be thrown out of engagement
whenever it is desired to turn the winch.
Upon the journal-hub of the sheave I¹, is formed a square or polygonal head to
receive a wrench, or some other suitable device is attached thereto or connected
therewith whereby the two sheaves, clamped together as stated, may be turned as
if integral whenever it is desired to stretch the belt.
Each sheave has a pin it, to receive a loop at the end of the cord led to it from
one of the sliding bars or boxes. One of the sheaves receives the long. cord from
the front box over the guide pulley as above described, and the other sheave
receives the short cord from the rear box stretched directly to it, its outer periphery
being in line with the hook on said box.
Now when the cords have been attached to the sheaves and hooks respectively,
they may be adjusted until the tension on each is the same and the movable drum

page_text: in exact parallelism with the opposite drum at the other end of the apron, simply
by loosening the pivot-bolt and turning one sheave upon the other. When this
adjustment has been perfected the bolt will be screwed home again, clamping the
two sheaves rigidly together, so that each must necessarily partake of the movement
of the other, and the apron-drum will, 'by any such movement, be co-ordinately
adjusted at each end.
Should one of the cords stretch, its slack will be taken up by a fresh adjustment
of the sheaves in their peripheral relations.
As a modification the rear sliding box may be provided with a straight rack M,
in place of the hooked arm, and the sheave receiving the cord from said box, will
be replaced by a spur pinion M, which will take into said rack. This pinion
will be axially adjustable, with reference to the sheave which receives the cord
from the front sliding box, in practically the same manner as before described, and
will be so proportioned relatively to that sheave, that the movement of the rear
box will take place co-ordinately with the movement of the front box. A guide-way
or a keeper m will be provided upon the bracket to hold the rack in engagement
with the pinion and ensure steadiness.
I
While the sheaves and their bracket are described in the preferable form of the
invention, as located at the rear corner of the platform, or other apron bearing.
frame, it is evident that it is a mere matter of convenience which corner they shall
be located at, and that the may even be located centrally between such corners,
and both cords made of equal length and led to them over guide-pulleys. With
the rack-modification, however, it is obvious that the pinion must be in line or
nearly in line with one of the boxes to receive the rack therefrom, and the position
of the bracket will accordingly be determined by this necessity.
The sheaves themselves have been described as formed respectively with a cupped
disk and an in-fitting disk with serrated faces, but the cup may be dispensed with
and the two disks or serrated contacting surfaces made flat or otherwise constructed
so that the proper interlockings at any desired adjustment is secured.
Having now particularly described and ascertained the nature of the said
