Improvements in and relating to Harvesting Machines.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co, Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement.-
-
This invention relates to improvements in butt adjusters for self binding
harvesters and 18 illustrated in the accompanying drawing in which.—
Fig 1 is a front elevation of as much of a self binding harvester as is necessary
to illustrate my invention
Fig 2 is a plan view with the grain cover indicated by a dotted line
Fig 3 18 a sectional elevation on the line 3-3 of Fig 1
The butt adjusting mechanism 18 located along the fiont edge of the binder
table B, as usual, between the elevator C and the binder frame D, and serves
to hasten the butts of the grain down the table to their final position thereon
E 18 the grain cover at the upper end of the elevator
The elevator has the usual canvases and e¹.
In
A 18 the adjuster bracket in which is journaled the adjuster crank shaft a',
preferably adapted to receive rotation from the lower elevator roller by means
of the bevelled gears e² and es At its upper end is formed a double crank a
the said bracket is also preferably pivoted a radius rod A¹ Hung upon wists
on the double crank are butt adjusting boards A³ and A' by means of suitable
arms a and a. The lower ends of the boards are supported by radius links a³
and a, said links being pivoted upon the swinging end of the radius rod A³,
and the boards being pivoted conveniently thereto by any suitable means, those
shown being brackets riveted there to Conveniently to the radius rod is pivoted the
usual adjuster lever F extending diagonally back to the top of the elevator within
convenient reach of the driver and provided with the usual means for holding
it in any given position of adjustment The double cranks are substantially
on opposite sides of the shaft a¹ so that one of the boards is acted upon the grain
aggressively when the other is making a return movement, preparatory to a
succeeding aggressive movement. As is well known, in some conditions of
grain there is a tendency for the upper elevator canvas to carry bunches of straw
back between itself and the grain cover and choke the elevator Similarly the
lower elevator, canvas sometimes carries straws down between itself and the upper
edge of the binder table The upper board can be of such length as to approach
veiv close to the upper elevator roller and the space thereabove where the straws
sometimes choke, so as to positively take the grun away from the same without
allowing it to be carried over, For that purpose its end nearest the roller 18
provided with an aggressive toothed slat at The lower board, hung upon the
lower crank while having preferably the same throw as the upper one, can he

before it is permitted to be called downward below the table
It also has a
claw or aggressive toothed slat at its upper end. Both boards are provided with
the usual aggressive slats a* along the length to aid in positively carrying the
grain downward
To the adjoining edges of the adjuster boards are attached plates a³ and a³
extending toward the front of the machine, the purpose of which is to prevent
straws from getting between the boards as they move in their orbital paths
It is found in practice that the action of my upper board upon the upper
portion of the mass of grain confined between the deck and grain cover tends
to move the portion that lies below For instance, if the board A³ alone were
used the whole mass of grain would be moved in the direction of the binding
receptacle proper The action of the board A³ would carry all straws with
which it came in contact and the agitation and forward movement of those would
so influence all the straws beneath as to cause them to move down the table
In other words, the mass of straws being free to move and partially influenced
by gravity, movement of the upper stratum would carry the lower stratum there-
with to a very great extent The converse is true, that if the lower one of the
two boards only were used the straws with which it came in contact would be
moved deliveryward and the straws above would also be influenced
to
move in the same direction The co-operation of the two boards
15 such as to not only move the straws endwise for adjusting them
80 as to be centrally bound but to, in effect, have two feeding
strokes downward to every revolution of the crank shaft carrying them
This double action is found in practice to be a very material benefit
I am
aware that butt adjusters have been made consisting of a series of toothed bars
moved by cranks and adapted to be thrust through slots in the frame guiding
them, in which case there are no means for producing a beating effect upon the
butts of the entire mass of grain in the receptacle, but only teeth that at various
horizons, as it were, above the binder table should dig into the mass and thus
feed it by clawing actions While this clawing action tends to work the grain
down it does not do so in a satisfactory manner
One important function performed by my device is not found in the single
board adjuster. In the conditions of grain found in the early harvest, the
packers force the straw downward, but as they withdraw, the latter springs
back until the succeeding packer brings down its wisp, and, furthermore, the
successive strokes of the packers, compacting the straw at the middle of the gavel,
produce a tendency of the butts of the straws to recoil under the action of the butt
adjuster With my device, this recoil is very nearly prevented by the alternate
strokes of the two parts, one acting upon the butt of the gavel while the other
18 making its return movement
Having now particularly described and ascertained the nature of my in-
vention and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claum is.-
1 The combination with the elevators the binding table and the grain-covel,
of a grain adjusting device consisting of orbitally moved boards arranged one
above the other and adapted to move in close relation to each other and also
adapted to act alternately, and thus engage the butts of the straws in the recep-
tacle, move them endwise and advance them deliveryward, each of said boards
having a plate attached to the edge adjoining its fellow-board, substantially as
described
2. The combination with the elevators, the binding table and the grain cover,
of a grain adjusting device consisting wholly of two orbitally moving boards
placed edgewise in close proximity to each other, the plane of said boards being
substantially perpendicular to the binding table, and said boards being operated
so as to act alternately upon the butts of the straw upon the table, to simul-

page_text: taneously move the same endwise and sidewise, whereby only one portion of the
adjuster is active upon the grain at a time, the other portion being meanwhile
out of action, substantially as described
3. The combination with the elevator conveyors, the binding-table, and the
grain-cover, of a grain adjusting device consisting wholly of orbitally moving
boards placed edgewise in close proximity to one another, the plane of said
boards being substantially perpendicular to the binder table, and said boards
being operated so that, although the entire face of the adjuster is constantly in
motion, the individual boards of which it is composed act alternately upon the
butts of the straw upon the table to simultaneously move the same endwise and
sidewise, substantially as described
4 In a grain binding harvester, the combination with the receiving table,
the grain cover, and the upper and lower elevating conveyors, of a grain ad-
justing device composed wholly of orbitally moving boards, one placed imme.
diately above the other, the lower board located and adapted to sweep in close
contact with the table, and the upper board located and adapted to sweep acioss
the plane of the lower conveyor toward and near the end of the upper conveyor
in close contact with the cover, and the two boards thus co-operating to clear
the space between the toller of the upper conveyor and the overhead cover and
between the roller of the lower conveyor and the edge of the receiving table, sub-
stantially as described
5 In a grain binding harvester the combination with the binder receiving
table, grain cover and upper and lower elevating convevors, of a grain adjusting
device composed of two orbitally moving boards, one above the other, the lower
one adapted to clear the space between the grain reqciving table and the
lower conveyor roller, and the upper one to keep clear the space between the grain
receiving table and the lower conveyor roller and the upper one to keep clear
the space between the upper elevator roller and the giain cover, and plates attached
to the adjoining edges of said boards and projecting outwardly and adapted to
prevent the straws from getting between said boards, substantially as described
