Year: 1876

page_text: LETTERS PATENT to William McIntyre Cranston, of 36, Worship Street
Finsbury, in the County of Middlesex, for the Invention of "IMPROVEMENTS
IN THRESHING AND STRAW BINDING MACHINES, THE TWO BEING IN COM-
BINATION."
Sealed the 19th January 1877, and dated the 24th July 1876.
PROVISIONAL SPECIFICATION left by the said William McIntyre Cranston
at the Office of the Commissioners of Patents on the 24th July 1876.
WILLIAM MCINTYRE CRANSTON, of 36, Worship Street, Finsbury, in the County
of Middlesex. "IMPROVEMENTS IN THRESHING AND STRAW BINDING MACHINES,
THE TWO BEING IN COMBINATION."
This Invention relates to improvements in threshing and straw binding machines,
the two being in combination, and consists in attaching the grain binder mechanism
to the tail end of a threshing machine, that the grain straws which are delivered
"broadside on from the beaters are delivered into or on to a cradle apron or pocket
of the grain binder and there divided into sufficient quantity by the binder arm to
form a bundle or sheaf to be lifted into the prongs and bound round with wire,
cord, or a straw band before the straws in bundle are thrown out on to the ground
or into a vehicle which may be drawn alongside for the purpose, or the bundles may
be delivered on to an elevator for stacking.
One way in which I purpose uniting the binder machine with the threshing
machine is by attaching poles or beams on the binder and passing the projecting
ends through loops or lugs on the side of the thresher as to bring the band or pulley
wheels in line, that the two can be driven from the same prime mover (and work in
unison) which may be in this case at the head of the threshing machine.
speed of the binder mechanism is in proportion to the issue of straws from the
thresher that no accumulation of straws can take place on the tail shoot of the
thresher.

WILLIAM MCINTYRE CRANSTON, of 36, Worship Street, Finsbury, in the County
of Middlesex. "IMPROVEMENTS IN THRESHING AND STRAW BINDING MACHINES,
THE TWO BEING IN COMBINATION."
This Invention relates to improvements in threshing and straw binding machines,
the two being in combination, and consists in attaching the grain binder mechanism
to the tail end of a threshing machine. that the grain straws which are delivered
"broadside on" from the beaters are delivered into or on to a cradle apron or
pocket of the grain binder and there divided into sufficient quantity by the binder
arm to form a bundle or sheaf and bound round with wire, cord, or a straw band
before the straws in bundle are thrown out on to the ground or into a vehicle
which may be drawn alongside for the purpose, or the bundles may be delivered
on to an elevator for stacking.
One way in which I purpose uniting the binder machine with the threshing
machine is by attaching poles or beams on the binder and passing the projecting
ends through loops or lugs on the side of the thresher as to bring the band or
pulley wheels in line that the two can be driven from the same prime mover (and
work in unison) which may be in this case at the head of the threshing machine.
The speed of the binder mechanism is in proportion to the issue of straws from
the thresher that no accumulation of straws can take place on the tail shoot
of the thresher.
The annexed Sheet of Drawings Figures 1 and 2 represent a portion of a
threshing machine with a grain straw binder fitted to the tail thereof as before
referred to.
A is the body of the threshing machine shown in this case upon wheels B as a
portable. C, C, are poles or struts as part of the straw binder with the inner ends
passed into and through loop lugs or socket plates D, D, on the machine sides
and in or to which the poles can be fastened temporarily by screws or other
appliances to make a firm attachment of one to the other. E, E, are side frames
or standards on the poles to carry the shaft F, on which the binding mechanism
is mounted, the parts being arranged within or between the side standards for the
collection of the straws as they leave the machine end G, after the grain has been
thrashed out of them in the ordinary manner. The straws fall upon and are
guided by the bars into the cradle I where they come into contact with curved
springs J, J, against which they are held " en masse for the needle or point of
the binder arm K, to pass through to divide a sufficient quantity of straws for
forming a bundle or sheaf.
"
I have selected the straw binding mechanism patented by me on the 24th day of
July 1875, No. 2629, as attached to the threshing machine shown in the Drawings,
but I do not limit myself exclusively to its use for the purpose as other forms or con-
structions of mechanism for gathering and binding grain straws may be attached
temporarily or permanently to the tail ends of threshing machines, the object of
my Invention being as before expressed. The collection and binding as a bundle
or sheaf of the grain straws as they leave a threshing machine to enable them to
be thrown on to the ground in bundles or on to a vehicle drawn alongside, or on
to an ordinary elevator, by which then can be lifted or carried to form a bundle or
stack without the unnecessary amount of manual labour now brought into use.
It will be seen that the binder arm shaft, which also actuates the compression
arm L, and the bundle discharging arm M is rotated by bevil gearing P, Q, from
ono side only, but it may be driven from both sides by the introduction of a second
set of bevil gearing upon the opposite ends of the shaft.
R is the bevil pinion shaft geared into by a clutch S on a second shaft T receiving
its motion from a pinion U on the shaft of one of the winnowing or jigging frames,

page_text: but it may be from any other part or by a strap or appliances direct from the
engine which works the threshing machine. V is a screen plate as a fender to
prevent the straws becoming entangled in the binding mechanism, which fender
inay extend across from side to side, especially when two sets of binding appliances
are fitted as in the plan view, Figure 2, in which however single strip plate fenders
are shown to render the Drawing clear.
The binding head K has the wire twisting and clipping or severing appliances
fitted in it as also the end of the wire or cord a which comes from the reel b, as fully
explained in the Specification of the Patent before mentioned.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I delare that I claim-
The adaptation of a grain straw binding apparatus of any kind to a threshing
machine of any kind, the two being as one machine, whereby the threshing opera-
tion and the binding operation of the straws can be effected as set forth.
Secondly. I claim fitting two distinct straw binding apparatus to the delivery
end of a threshing machine either on one frame or on separate frames and working
from one shaft or from or by separate shafts driven to ensure the binders acting in
unison for binding the gathered straws into bundles or sheaves at two parts of their
length.
Thirdly. I claim the special adaptation of the binding apparatus or appliances to
a threshing machine shown with reference to the annexed Drawings.
In witness whereof, I, the said William McIntyre Cranston, have hereunto
set my hand and seal, this Twenty-third day of January, One thousand
eight hundred and seventy-seven.
