COMPLETE SPECIFICATION.
Improvements in Apparatus for Binding Straw and the like.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County, of
Middlesex, Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, as communicated to me by Friedrich
Biel, of Sebexen, near Calefeld, Germany, Gentleman, to be particularly described
and ascertained in and by the following statement:―
This invention relates to improvements in apparatus for binding straw and the
like whereby the binding process is not wholly automatic as heretofore, but the
strap or the like is put around the truss by hand; thus simplifying the arrange-
ment of the apparatus and completely avoiding trouble in its management.
In the accompanying drawings an apparatus of this kind is illustrated, Fig. 1
being an elevation, Fig. 2 a partial horizontal section and Fig. 3 a partial
front view.
By way of example the apparatus is shown in combination with a thrashing
machine. The straw, coming from the straw-shaker enters a hopper a, Fig. 1
which communicates with a receptacle 6 which is provided with a number of
vertical slots b¹, so arranged that one end of each of a series of rocking levers & can
enter the receptacle 6 through one of these slots. These rocking levers c are
supported in proximity to the ends which enter the receptacle by cranks f on a
continually rotating crank shaft. The other end of each of these rocking levers c
is coupled to one of a series of connecting rods e swinging around the fixed pivot d.
Consequently that end of the rocking lever c which enters the receptacle 6 has a
substantially elliptical motion. The cranks f rotate in such a direction as to cause
the rocking levers c to enter into the receptacle b at the beginning of their down-
ward motion and to leave this receptacle before the downward motion has been
finished. In this manner the straw or the like is compressed within the lower
part of the receptacle b which therefore forms the compressing chamber. This
process of compressing the straw or the like is continued as long as a slider g
forming the bottom of the compressing chamber, remains in the position shown by
full lines in Fig. 1, when it takes the position shown by the dotted lines in Fig. 1
the compressed straw will enter the horizontal chamber h. This movement of the
slider g to the sloping position and its return to the original position is caused by
means of the connecting rods i and by the crank pins, Figs. 1 and 2. When the
slider g passes to the downward position it takes along with it by means of its
downward projecting shoulder g¹ the compressed straw till the latter is prevented
by means of the lever abutment kk from continuing its movement, this abutment
being in its closed position as shown by full lines in Figures 1 and 2. Now as
the lever abutment kk is provided in its middle with a void , Fig. 3, and as
furthermore the bottom and the top of the chamber are provided with voids /.
Fig. 1, and the slider g with a void g³ Figs. 1 and 2, the strap can be put around
the compressed straw by hand without any difficulty, while the straw is held
together by means of the shoulder g' and the lever abutment kk. Finally the bundle is
freed, as soon as the lever abutment k k is opened into the position shown by dotted

page_text: lines in Fig. 1. This movement is effected by means of the connecting rods m,
coupled to the levers of the abutment k. Each pair of these connecting rods m
is coupled with one end of the connecting rods n, the other ends of which are
connected to the crank pins o. These crankpins à as well as those marked are
rotating continually. As soon as the slider has been brought back into
its normal position, that is to say into the position shown by the full lines in Fig. 1,
the process can be repeated, as the lower end of the compressing chamber formed
by the receptacle 6 is thereby closed again.
Any other suitable mechanism may be used for effecting the above described
movement of the rocking levers_c. Also the mechanism co-operating with the
slider and the lever abutment kk can be varied in any suitable manner.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
Apparatus for binding straw and the like in which the straw or the like is
compressed within a receptacle b, by means of rocking levers c whose ends have a
substantially elliptical movement and pass through vertical slots in the
receptacle b, so as to enter it while the downward motion begins and to leave it
again at the end of the downward motion, the compressed straw or the like being
allowed to enter a horizontal chamber has soon as the slider g, is brought from its
position shown by the full lines in Fig. 1 into that shown by the dotted lines, while
in the rearward motion of this slider ga shoulder g¹ thereon presses the straw
against a lever abutment kk which remains closed during this motion and is
provided with a void to allow, together with the voids of the chamber h and
with the void of the slider g, the strap to be put around the truss, substantially
as set forth and for the purpose specified and illustrated in the accompanying
drawings.
