Improvements in Harvester Binders.
I GEORGE BARKER of 77 Colmore Row Birmingham in the County of Warwick
Consulting Engineer do hereby declare the nature of the said invention as communi-
cated to me from abroad by Lyman Melvin Jones Manufacturer and James Wedlake
Machinist both of the City of Brantford in the County of Brant in the Province of
Ontario Canada to be as follows:-
The object of the invention is to arrange the elevator of the harvest-binder in such
a manner that it will freely elevate grain longer than the width of its canvas also act
so lightly on the heads of the shorter grain that all danger of threshing the grain is
avoided, and accomodate itself to elevate continuously heavy or light grain holding
it with sufficient pressure to prevent it working endways and it consists essentially of
a frame provided with suitable rollers to support the upper elevating canvas the said
frame being connected at one end only to the elevator frame, the other end being left
open so that should the grain cut be longer than the width of the elevating canvas the
heads of the grain may project outside of the said canvas or even beyond the table and
yet be elevated to the grain receptacle as freely as though the entire length of the
grain was acted upon the rear end of the upper elevating frame being perfectly free
or supported in such a manner that the grain being elevated will adjust the said frame
vertically to accomodate the thickness of the grain being elevated substantially as
hereinafter more particularly explained.
The upper canvas rollers are suitably journalled on end pieces the spindle of at least
one of the rollers projects through the elevator side piece and is provided with a gear
or sprocket wheel in order to connect with the driving mechanism of the machine.
There is nothing new in the arrangement of the gearing for driving the rollers but
the journals and journal boxes or their connections must be arranged in the elevator
side piece to permit the clevator frame formed by the rollers and end pieces to
rock when the rear end of the frame is raised by the passing of the grain between the
two elevating canvasses.
The elevator side piece which in other machines is placed on the rear of the elevator
similar to the front side piece is in this case removed by which means the heads of
any long grain which may be elevated will extend beyond the upper canvas and in fact
may project outside of the machine.
The rear end of the upper canvas frame may be left perfectly free as its weight will
generally be found sufficient to cause the canvas to act upon the grain I may however
connect the rear of this frame at each end to the seat board by a bolt extending from
the bar and passing through a slot made in the bracket which is fastened to the end
piece. By this arrangement the loose end of the frame of the upper canvas is supported,
but at the same time is so held that it may be pushed upwardly to leave sufficient
space for the passage of the grain being elevated.'
In order to provide additional pressure on top of the grain I provide a spring bar
connected at one end to the ordinary bar and passed through an eye bolt fixed to the
end piece.
I do not confine myself to any particular location for either the spring or the
brackets as they may be placed in any suitable position or as I have before intimated
they may be dispensed with altogether. In order to support the rear of the seat board
so that the said support shall not interfere with the passage of the grain when longer
than the width of the elevator table I provide an iron or steel support rigidly bolted at
its lower end to the sill or its equivalent and extending obliquely from that point
beyond the end of the machine where it extends uprightly to form a support. The

page_text: said support after leaving the sill or its equivalent rests upon an extension of the
wheel frame or its equivalent and extends obliquely leaving sufficient space below it
to admit the truck wheels commonly employed for transporting the harvester.

COMPLETE SPECIFICATION.
Improvements in Harvester Binders.
I, GEORGE BARKER of 77 Colmore Row Birmingham in the County of Warwick
Consulting Engineer & Patent Agent do hereby declare the nature of my said inven-
tion as communicated to me from abroad by Lyman Melvin Jones Manufacturer and
James Wedlake Machinist both of the City of Brantford in the County of Brant, in
the Province of Ontario, Canada and in what manner the same is to be performed to
be particularly described & ascertained in & by the following statement :---
The object of the invention is to arrange the elevator of the harvester binder in such
a manner that it will freely elevate grain longer than the width of this canvas; also
act so lightly on the heads of the shorter grain that all danger of threshing the grain
is avoided, and accommodate itself to elevate continuously heavy or light grain, holding
it with sufficient pressure to prevent it working end ways; and it consists essentially
of a frame provided with suitable rollers to support the upper elevating canvas, the
said frame being connected at one end only to the elevator frame, the other end being left
open so that should the grain cut be longer than the width of the elevating canvas the
heads of the grain may project outside of the said canvas, or even beyond the table
and yet be elevated to the grain receptacle as freely as though the entire length of
the grain was acted upon; the rear end of the upper elevating frame being perfectly
free or supported in such a manner that the grain being elevated will adjust the said
frame vertically to accommodate the thickness of the grain being elevated, substantially
as hereinafter more particularly explained.
Figure 1 is a perspective view of the elevating table of a harvester, the upper
elevating frame being arranged substantially in accordance with my invention the
canvas of the said upper elevating frame being removed.
A, represents the upper canvas rollers suitably journaled on the end pieces B, C.
The spindle of at least one of the rollers A projects through the elevator side piece D
and is provided with a gear or sprocket wheel in order to connect with the driving
mechanism of the machine.
I do not claim anything peculiar in the arrangement of my gearing for driving the
rollers, A, and therefore I do not exhibit the said gearing in the drawing. I may
mention however, that the journals, journal boxes or their connections must be
arranged in the elevator side piece, D, to permit the elevator frame formed by the
rollers A and end pieces B, C, to rock when the rear end of the frame is raised by the
passing of the grain between the two elevating canvasses.
It will be observed that I have removed the elevator side piece, which in other
machines is placed on the rear of the elevator, similar to the front side piece, D; shown
in drawing. By this rear side piece being removed, the heads of any long grain
which may be clevated will extend beyond the upper canvas, and in fact may project
outside of the machine.
The rear end of the upper canvas frame may be left perfectly free, as its weight will
generally be found sufficient to cause the canvas to act upon the grain. In the drawing
however, I show the rear of this frame connected at each end to the seat board E by
a bolt F, extending from the bar M and passing through a slot made in the bracket G,
which is fastened to the end piece, C, as indicated. By this arrangement the loose
end of the frame of the upper canvas is supported, but at the same time is so held that
may
be pushed upwardly to leave sufficient space for the passage of the grain being
it

page_text: elevated. In order to provide additional pressure on top of the grain, I provide a
spring bar H connected at one end to the bar M, and passed through an eye bolt J,
fixed to the end piece C.
I do not confine myself to any particular location for either the spring H, or the
brackets G, as they may be placed in any suitable position or as I have before intimated
they may sometimes be dispensed with altogether. In order to support the rear of
the seat board E so that the said support shall not interfere with the passage of the
grain when longer than the width of the elevator table, I provide an iron or steel
support K, rigidly bolted at its lower end to the sill L or its equivalent and extending
obliquely from that point beyond the end of the machine, where it extends uprightly
to form a support as shown in Fig. 1. The said support after leaving the sill, L, or
its equivalent, rests upon the extension, N, of the wheel frame or its equivalent and
extending obliquely, as shown in the drawing, leaves sufficient space below it to admit
the truck-wheels commonly employed for transporting the harvester.
Having now particularly described & ascertained the nature of my said inven-
tion and in what manner the same is to be performed to be particularly described &
ascertained in & by the following statement :-
1. In a harvester-binder an upper elevating canvas frame, loosely supported in such
a manner that it will move vertically to suit the thickness of the grain being elevated
substantially as hereinbefore specified.
2. In a harvester-binder, an upper elevating canvas frame, free at one end but
flexibly connected at its other end to the front of the elevator, the rear side piece of
the said elevator being removed, substantially as hereinbefore specified.
3. In a harvester-binder an upper elevating canvas frame, free at one end but
flexibly connected at its other end to the front of the elevator, the rear side piece of
the said elevator being removed in combination with a spring or springs arranged to
act upon the rear side of the upper elevating canvas frame substantially as herein before
specified.
4. A diagonal support K bolted to the sill L, and resting on the extension N of the
wheel frame extending obliquely to a point outside of the elevator frame where it is
turned upwardly to form a support for the rear of the seat board E substantially as
hereinbefore specified.
