Improvements in or relating to Apparatus for Packing and Baling
Straw, Hay, and the like.
A communication from C. A. KLINGER, Maschinenfabrik, of Altstadt-Stolpen, Saxony,
in the Empire of Germany.
I, ALFRED JULIUS BOULT of 111 Hatton Garden, in the County of Middlesex,
Chartered Patent Agent 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:-
The present invention relates to a baling press in which an arrangement is made
for automatically introducing into the packing space the straw or the like to be
packed and also for introducing between the bales the material necessary for binding
each bale.
For this purpose the straw or the like is placed in an even layer on the transport
table is at first gripped by a number of upright prongs or teeth which pass through
recesses or grooves in the table and reciprocate both vertically and horizontally and is
then supplied to a second rake or feeder which draws the straw into the packing
chamber evenly and smoothly.
A horizontally moving piston strongly compresses the straw in the cylinder or
chamber which is tapered towards the exit end; then the binding material the end or
ends of which are secured in the forked end of a piercer or piercers which are
secured to a transverse bar connecting two pivotted levers to which the piston levers
are attached is introduced with the descending piercer between the packed straw.
After the presser-piston has strongly compressed the bale, the levers are released
by hand or by a ratchet-device actuated by the advancing piston, in order to cause the
piercer to descend.
During the return of the piston the lever-system comes downwards, whereas during
the advance of the piston said levers are pressed upwards and rotained by the ratchet-
device. At the same time the lower end of the binding material which is provided
with knots or otherwise thickened, has been stopped by a spring jaw or jaws arranged
under the packing chamber, so that it is held vertically in the packing material and is
transported with it through the machine.
The present invention has the advantage over baling presses used hitherto of
dispensing with the use of clumsy and heavy dividing boards; the bales may be tied
without the slightest difficulty with the binding material when leaving the machine,
said binding material being automatically introduced. In consequence of the dividing
boards being dispensed with, the packing space is of less height towards the discharge
end so that the bales carried to the back are also extremely well pressed.
Fig. 1 of the accompanying drawings is a side elevation, the full lines show the
arrangement of levers and of the prongs or forks in the position of rest, the lowest
position of said levers and the highest position of the prongs after the release of the
ratchet, being shown in dotted lines.
Fig. 2 shows the levers in the position which they occupy when the piston is in its
foremost position; the dotted lines indicate the released ratchet-device.
Fig. 3 is a cross section of the press.
The operation of the machine is as follows:-
The straw or the like to be packed is guided from an inclined plane a by means of
the prongs b secured to the piston rod 6' of the piston b (which prongs may be

page_text: connected to form a rake) into the packing or baling chamber by reason of the
prong passing, owing to the movement of the rod through elliptical paths
according to their position on the piston rod. These paths shown in Fig. 1 are so
arranged that during their advance the prongs rise upwards and passing through the
table, push forwards the straw placed on it, and during their return movement pass
beneath the table.
The straw thrown into the packing space is compressed to the desired degree by the
reciprocating piston b. The rods d remain hanging loosely downward when in the
position of rest, that is to say when the levers e are in their highest position or when
the connecting rod 9 rests in the upper notch of the ratchet device h. At the end of
each stroke the rods d are slightly pushed back by the rollers c laterally projecting
from the piston b whereby the levers e will be caused to move upwards. The
connecting rod g may then be released from the ratchet device as shown in Fig. 2.
In this position the operator after having passed the thickened end of the binding
material through the lower forked ends of the piercer or piercers f can release
the levers de the lower claw-like end of the rod d pressing against the laterally
projecting rollers c and remaining pressed against them by the weight of the whole
system of levers de g. The lower claw of each lever d is moreover of such shape that
it embraces the rollers e (Fig. 1 dotted lines) the more the returning piston approaches
its original position and consequently the more the rod d (accompanying the piston in
its movement) approaches the horizontal line, so that the roller c draws with it
the rod d, when the weight of the framing becomes less. Thus the. piercers are
guided directly behind the bale through the packing space, till they project below the
outer edge of a spring catch or blade i arranged under the packing chamber for
engaging with and retaining the binding material.
During its next advance the piston b raises the levers d e and the piercer, when
said parts are held by the pawl-device h.
The binding material is held back during the rising of the piercer by the catch i
and is clamped against the newly introduced material and is transporte 1 together with
the latter to the discharge opening at the next reciprocation of the piston, for this
purpose there are arranged longitudinal slots in the bottom and in the top of the
packing chamber.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. In a packing ог baling press for straw and the like, the combination of a piercer
or piercers carrying the binding material and levers operated by the presser piston
whereby the piercers upon the release of the lovers pass downwards through the
packing chamber and then are raised during the advance of the piston, the end of the
binding material being held back by a catch substantially as described.
2. In a packing or baling press for straw and the like a prolonged bar or rake
arranged on the presser piston rod and having an upward and reciprocating notion
by means of which the straw or the like is automatically conducted from the table to
the packing chamber substantially as described..
3. The combination and arrangement of parts forming the complete machine for
compressing straw and the like into bales, and introducing binding material
substantially as described and illustrated in the drawings.
