I, GEORGE EDWARD VAUGHAN, of No. 57, Chancery Lane, in the county of Middlesex,
Patent Agent, do hereby declare the nature of this invention, a communication to me
from abroad by William Andrews and Arthur Ward Beaven, both of Christchurch,
New Zealand, Engineers, trading as Andrews and Beaven, and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:
Machines for pressing chaff into bags and sacks have been hitherto employed in
connection with chaff cutting apparatus, and this invention relates to improvements
in machines which are in general use for such purpose in the Australian Colonies and
New Zealand and which are constructed and employed substantially in the following
manner. The said machines consist of a screw, of one or more blades, revolving
within a cylinder through which the chaff descends into the bag. The said bag is
drawn up on the outside of the cylinder and is secured in position thereon, by means
of a ring or platform, and the said ring or platform is connected by means of chains,
cords or rods, with a brake, or counterbalancing weights, or the bag itself is, in some
cases, connected directly to the brake or counterbalancing weights. The brake or
weights are so regulated that they allow of the descent of the hag, at the desired rate
of speed, as the chaff is pressed into the same; the amount of chaff so pressed in
being regulated by the amount of resistance to the descent of the bag exercised by
the said brake or weights. In employing such machines it has been usual to stop the
screw from revolving when it has been desired to remove a full bag, and to restart the
same when an empty bag has been placed in position on the cylinder. The variations
of strain upon the motor caused by the stopping and restarting of the same, as lastly
referred to, are very objectionable and, in order to obviate the disadvantages arising
therefrom, bagging machines constructed in accordance with this invention are
provided with two screw presses of the nature herein before stated. Such presses are
placed side by side and have arranged in connection therewith a binged plate or turn-
over or slide which serves to direct the feed of chaff into one of the cylinders and
when the bag thereon has been filled, the said hinged plate or slide is moved, either

page_text: automatically or otherwise, and it then directs the chaff into the second cylinder. In
addition to the said hinged plate or slide a sliding clutch is arranged so that when one
bag has been filled, the motor is thrown out of gear with the screw within the cylinder
on which such bag is arranged and placed into gear with the screw in the second
cylinder. It will be understood that the hinged plate or slide is suitable for employ-
ment in connection with double chaff bagging machines independently of the clutch
for transferring the motive power from the shaft of one screw to that of the other,
and that likewise the arrangement of the said clutch may be employed without the
hinge plate or slide.
The before mentioned hinged plate is hinged or pivoted or arranged between the
upper ends of the two cylinders, and a lever is connected thereto. When it is desired
that the hinged plate shall be moved automatically, cords connected to the bag rings are
respectively connected to the ends of the said lever so that when the bag being filled
reaches its lowest point on the cylinder, the cord attached thereto moves the hinged
plate over thereby causing the supply of chaff from the hopper to be directed into the
other cylinder. It will be readily understood that the hinged plate may be moved by
the attendant. The construction and arrangement of the slide which is, in some
cases, used instead of the hinged plates, will be readily understood by reference to the
drawings.
In the accompanying drawings Figure 1. is a front elevation of a
bagging machine
provided with a hinged plate, as hereinbefore described, and Figure 2. is a side elevation
of the same. In both these figures the same letters of reference indicate like parts,
A1 A2 are the cylinders B¹ B2 the screws which are driven by any suitable and desired
means; C. are the bags; E. is the elevator; E¹ the hopper; F. the hinged or pivoted
plate or turnover; the dotted lines F¹ indicate a slide which is, in some cases,
employed instead of the said plate or turnover F, and G¹ is the lever for actuating the
slide, in this case, the hopper has two openings either one of which is, as the case may
be, closed by the said slide F¹. G. is the before mentioned lever attached to the
hinged plate F., 11 12 are chains, cords or rods connecting the ends of the lever G
to the bag rings H H. The hinged plate F. moves in arc of circle J J².
The spindles D' of the screws may be driven through the medium of the pulleys D.,
or the said spindles have, in some cases, fitted thereon the bevel wheels D³ gearing
into similar wheels D4 loosely mounted on the spindle Ds. On the said spindle D³,
between the bevel wheels D4, is the sliding clutch K. which is moved into gear with
either of the wheels D by the lever L. which is connected with, and moved by, the
rings of the bags in a manner similar to the lever G.
Instead of employing bevel gear as lastly described in connection with the clutch K.
any known mechanical equivalents, such as, fast and loose pulleys may be substituted
therefor.
In the machines illustrated in the accompanying drawings the descent of the bag
is governed by the brake which consists of the ratchet wheel W. which is mounted
loosely on its spindle and is gripped by means of the screw nut T. between two
friction blocks X₁X². The chains, cords or belts v. connected to the bag rings H'H²,
are wound round the pulleys Z.; S. is a spring under the nut T.; R. is a sheave
round which a cord or chain R¹ is wound in opposite direction to the belts or chains on
the pulleys Z. this cord or chain is used to wind up the last mentioned belts or chains
and to draw the empty bag on to the cylinder.
The inner block X is attached to one of the pulleys Z. or is keyed on the spindle
thereof. The ratchet wheel W., which is mounted loosely on the brake spindle, revolves
backward, together with the friction blocks X1 X2, pulleys Z. and sheave R., when
the cord R¹ is pulled. The pawl R² prevents the ratchet-wheel from revolving when
geared therewith as shown, the friction between the blocks X1 X2 and ratchet-
wheel W. prevents the unwinding of the chain off Z. except when the weight in the
bag or pressure of the screw overcomes the resistance of the blocks X'X'.
The term "bag ring." hereinbefore employed is intended to refer to the ring or
platform for holding or supporting the bag or to any part or attachment of the latter
which partakes of the same movement.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
First. In chaff bagging machines of the nature hereinbefore described, the combina-
tion and arrangement of the two screw presses, the turnover or slide and the bevel
gear and clutch, substantially as, and for the purposes, hereinbefore described and
shown in the accompanying drawings.
Secondly. In chaff bagging machines having two screw presses, the combination and
arrangement of the hinged or pivoted plate or turnover F. or slide F¹ and lever G
or G, substantially as and for the purpose hereinbefore described.
Thirdly. In chaff bagging machines having two screw presses and provided
with a hinged plate or slide, the connection of the bag rings or bags with the lever G
or G', referred to in the second claim, whereby the plate or slide is automatically
moved by the descent of the bag, substantially as, and for the purpose, herein before
described and illustrated in the accompanying drawings.
Fourthly. In chaff bagging machines having two screw presses, driving the screw
spindles through the medium of bevel wheels mounted loosely on a shaft, driven by
any suitable motor, on which shaft is a sliding clutch which is geared into either of
the bevel wheels on the said shaft by hand by means of a lever arranged in connection
therewith, substantially as, and for the purpose, herein before described.
And Fifthly. Connecting the lever referred to in the fourth claim with the bags or
bag rings, substantially as, and for the purpose hereinbefore described.
Dated this Seventh day of December 1887.
