PROVIDINAL SPECIFICATION.
An Appliance by Means of which Chaff, Bran and similar Materials
may be Compressed into Bags without putting any Pressure on
the Bag during the Process.
BRYAN CORCORAN, 31, Mark Lane, London, E.C., Engineer, do hereby declare
the nature of this invention to be as follows:-
My invention is an appliance by means of which chaff, bran, and similar
materials may be compressed into bags without putting any pressure on the
bag during the process.
In carrying out my invention I employ a tube of such a diameter as to loosely
fit the sack, and of suitable length, which is capable of being raised or lowered
by any convenient means.
Moving in this tube I employ a plunger capable of exerting the required
pressure and which may either compress the material with one stroke or may
perform the operation by a succession of strokes each stroke descending a less
distance.
The method of using my appliance is as follows
The bag or sack is suspended by some convenient means so that the bottom
rests on the floor (or it may be placed over the tube).
The tube is then lowered into the bag, and the material to be compressed
fed into the tube either all at once or by instalments the plunger then descends
and compresses it either with one continuous stroke or with a succession of
strokes, more of the material being fed in at each stroke, until the entire
quantity is compressed into the required space, the tube is then withdrawn from
the sack, the plunger remaining stationary: when the tube has been completely
withdrawn the plunger also rises and the bag may then be removed with the
compressed material inside.

BRYAN CORCORAN, 31, Mark-Lane, London, E.C., Engineer, 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: -
My invention is an appliance by means of which chaff bran and similar

page_text: materials may be compressed into bags without putting any pressure on the bag
during the process.
In carrying out my invention I employ a tube of such diameter as to loosely
fit the sack and of suitable length, which is capable of being raised or lowered
by any convenient means.
Moving in this tube, I employ a plunger capable of exerting the required
pressure and which may either compress the material with one stroke or may
perform the operation by a succession of strokes each stroke decending a less
distance.
The method of using my appliance is as follows
The bag or sack is suspended by some convenient means so that the bottom rests
on the floor (or it may be placed over the tube). "
The tube is then lowered into the bag and the material to be compressed fed
into the required space, the tube is then withdrawn from the sack the plunger
remaining stationary when the tube has been completely withdrawn the plunger
also rises and the bag may then be removed with the compressed material inside.
In order that my said invention may be fully understood I shall now proceed more
particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures.
Fig. 1 of my drawings represents a front elevation of an appliance constructed
according to my said invention. Fig. 2 is a sectional side elevation of the same
corresponding to Fig. 1. Fig. 3 is a plan corresponding to Fig. 2.
A is a tube of circular or any other convenient section capable of holding the
required quantity of chaff, bran or other material and which is capable of being
raised or lowered by means of the rack B, B, which receive their motion from
the pinions CC driven by means of fast & loose pulleys and cross & open straps D
being the fast pulley & E & E, loose pulleys F is the striking gear by means of
which either the cross or the open strap may be shifted onto the fast pulley,
it will readily understood that supposing the open strap on the fast pulley revolves
the pinion C in such a direction as to raise the tube A; when the crossed strap
is shifted on to the same pulley the pinion C will be revolved in the opposite
direction and so lower the tube. G G are the stops on a rod connected with the
striking gear and which automatically throw the straps onto the loose pulley
when the tube has reached the end of its stroke. I is the shoot by means of
which the chaff bran or other material may be fed into the tube. K is the
plunger of the same section a the tube A. and of such a size as to loosely fit the
tube, and is capable of being raised or lowered by means of the rack L actuated
by the pinion M and a train of wheels giving a suitable mechanical advantage
which is also driven by means of fast & loose pulleys & crossed & open straps,
N being the fast pulley & 0, 0, the loose pulleys P P are stops on a rod con-
nected with the striking gear, which automatically throws the straps on the loose
pulleys when the plunger has reached the end of its stroke. QQ are the handles
by means of which the striking gears may be worked by hand, or I may employ
an automatic device to do this.
In using my invention the bag or receptacle R is hung up as shown with its
bottom resting on the floor or platform the tube A is then lowered into the sack
as shown in Fig. 1 and the material to be compressed fed in by means of the
shoot I when, the required quantity has been fed in the plunger descends until
the material has been compressed into the desired space as shown by the dotted
line T the plunger is then stopped automatically by means of the stop P the tube
is now withdrawn clear of the sack as shown by the dotted line U the plunger
remaining at its lowest position and the material which was compressed in the
tube now fills the sack the sack so filled may be removed on raising the plunger K,
another sack taking its place.
I have shown in the foregoing arrangement a method of carrying out my
invention worked by means of racks & pinions and fast & loose pulleys but I do

page_text: not claim this as part of my invention which I may carry out in many other
ways.
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:-
-
1st. The employment of an apparatus for compressing chaff bran or other
similar material into bags without putting undue pressure on the bag or sack.
