PROVISIONAL SPECIFICATION.
A New Method of Collecting the Straw from Thrashing Machines

therefor.
I JOHN JOHNSON of Tarvin in the County of Chester Threshing Machine Owner
Machinist and Brick Merchant do hereby declare the nature of this invention to be as
follows:-
This invention relates to threshing machines and consists in collecting the straw as
it leaves the threshing machine in bundles of different weights as may be required and
so economizing hand labor and enabling the process of binding to be expedited.
For this purpose I employ a suitable weighing machine or apparatus on to which
the straw falls or is delivered from the threshing machine and such weighing apparatus
is overbalanced by the weight of straw (at any desired point) and thereupon delivers
the bundle of straw for tying up thus the straw is delivered and bound in bundles
all of equal weights.
The Weighing apparatus can be adjusted so as to deliver all the bundles of greater

A New Method of Collecting the Straw from Thrashing Machines
and Separating the same into Weighed Bundles and Apparatus
therefor.
I JOHN JOHNSON of Tarvin in the County of Chester Threshing Machine Owner,
Machinist, and Brick Merchant, 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 threshing machines and consists in collecting the straw
(as it leaves the threshing machine) in bundles of different weights as may be required
and so economizing hand labor and enabling the process of binding to be expedited.
For this purpose I employ a suitable weighing machine or apparatus on to which
the straw falls or is delivered from the threshing machine and such weighing apparatus
is over balanced by the weight of straw (at any desired point) and thereupon delivers
the bundle of straw for tying up thus the straw is delivered and bound in bundles all
of equal weights.
The weighing apparatus can be adjusted so as to deliver all the bundles of greater
or less weight as desired and as hereinafter described.
And in order that my invention may be clearly understood and readily carried into
practice I will proceed to describe the drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shoves a side view and Figure 2 an and view of annaratus annlied to the

page_text: spindle 6' which by means of the band gives motion to the crank pin wheel c the
crank pin c of which gives motion by means of the connecting rod ² to a slotted
arm on the axis of the batten beater which beats down the straw as it is delivered
from the shakers a a causing it to fall on to and accumulate upon the rotating saddle d
on the rotating arm & carried by the shaft d* until it overcomes the retaining force of
the spring against the friction roller dix. When thus released the table d then
makes a partial revolution on its axis d* and delivers the portion of straw thus
weighed or delivered in successive equal quantities on to the receiver e ready to be
tied up into a bundle. By this movement another saddle d is brought into position to
receive a corresponding quantity of straw to form another bundle the operation being
thus repeated so long as the straw is delivered on to the saddle or balanced table d.
fis a stay to support the frame which carries the axis of the batten beaters 1.
Figure 3 shews a modified arrangement of the rotating saddles or shelves & which
hold the straw as it accumulates thereon until its weight acts to release a bolt
and allow the shelf to make half a revolution and thus deliver the straw collected
thereon.
dd are revolving shelves fixed on the shaft dx direct under the shakers a a. On
these shelves are placed loose shelves which are held up by a spring d³ on
the underside of each rotating shelf & the strength of which can be regulated so as
to determine the weight of the quantity of straw delivered in successive equal quantities.
To these loose shelves are fixed sliding bolts d projecting on the outward edges of
the shelves dd. The onds of the bolts d' catch against the roller ex carried by the frame
work e underneath the shakers a a to hold the shelves d d secure in position until the
bolt is released by the determined weight of straw collected upon the shelf d².
is a side retaining spring to prevent the revolving shelves from turning backwards.
While the straw is being compressed by the straw packer or batten beater the
packer presses the straw as it falls from the shakers a « on to the loose shelves d³ ³
until sufficient straw for a batten or bundle is obtained. When the weight of the
straw presses down the loose shelf and bolt combined the weight of the straw
withdraws the bolt d' and releases it at the top when the rotating shelf d is free to turn
round into its next position and delivers the batten or bundle of straw into the iron
cago beneath alternately, as previously described with reference to Figures 3 and 4.
The straw packer is mounted on a rocking shaft I carried at each end on suitable
supports and brackets. On one end of this rocking shaft is keyed a crank with a
long slot projecting towards the end for a moveable crank pin. From this crank pin
is taken a connecting rod to another crank on the end of the shaft that drives the
shakers. On this rocking shaft there are projecting arms for pressing the straw on
to the loose shelves d' as it falls from the shakers a.
To the end of these arms is fixed a suitable shield to prevent the straw from getting
on to the top of the arms fixed to the rocking shaft. while at work.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is,
The improved method and apparatus for collecting the straw (as it comes from the
shakers of a threshing machine) on to rotating arms which are retained from time to time
by a spring, sliding bolt or other suitable contrivance until the load of straw overcomes
the pressure or holding power of the spring or withdraws the bolt to release the
rotating arm and thus deliver the straw in uniform quantities substantially in the
manner hereinbefore described with reference to Figures 1, 2 and 3 of the Drawings
hereto annexed.
