Improvements in the Construction of Bundling Presses for
Compressing Yarns.
I JOHN CORRIGAN of 11 Grafton Street Chorlton-on-Medlock Manchester in the
County of Lancaster Machinist do hereby declare the nature of this invention to bo
as follows
This invention relates to the construction of what are known as bundling presses
used for compressing yarns, my object being to simplify such construction, to render
the action of the press noiseless and to facilitate the unlocking and removal of the top
bars after the bundle has been compressed.
Instead of actuating the follower of the press by crank pins and connecting rods as
usual in this class of press I provide it with a vertical rack beneath, gearing directly
into the pinion which is actuated by suitable compound gearing. Upon the first
driving shaft I mount a ratchet wheel provided with a pawl or catch as usual but
instead of allowing the pawl to remain continually in gear with the said wheel
I provide it with a projection (or a tail piece) by which it is held, away from the
ratchet wheel, and which is acted upon by any convenient moving part of the press,
so that when the bundle is sufficiently compressed the pawl or catch is allowed or
caused to fall into gear and so retain the follower in its position. This renders the
action of the press noiseless.
Many devices may be adopted for this purpose but I prefer the following
means.
I mount a light lever upon the frame of the machine one end of which is beneath
the setting on handle and the other end beneath the projection on the ratchet pawl
or catch above named.
"
Thus when the setting on lever is depressed to start the compression of a "bundle
it will depress the before mentioned light lever raising its other end and with it the
pawl or catch, but as soon as the compression is completed, the usual automatic stop
motion moves the stop rod and allows the setting on lever (which is weighted at its
other end) to rise and release the catch lever thereby allowing the pawl or catch to
all into action and retain the follower in position.

page_text: If preferred the end of the catch lever may be cranked or so formed as to act
beneath the pawl or catch itself.
In order to facilitate the unlocking and removal of the top plates after the "bundle"
has been compressed I uso either sliding bolts or hinged latches working in holes in
the front plates or bars, but in either case I provide each of the said bolts or latches
with a tail piece so curved or cranked that the attendant, when making use of the
ordinary bar for simultaneously unlocking all the said top plates, can place it under
the tail pieces and thus with one continuous movement he can unlock and push up all
the top plates out of the way for removing the "bundle."
When hinged latches are used 1 propose to provide a hook or bracket on each of
the outside front plates, so that when the latches have locked the press the lifting
bar above named can be set in front of all of them and held in the said hooks or
brackets thus preventing the latches from becoming accidentally displaced.
I also continue each top plate beyond the hinge by which it is connected to the
back plate of the machine and provide this continuation with a suitable counterbalance
weight to facilitate the lifting of the said top plate by the attendant.

Improvements in the Construction of "Bundling-presses" for
Compressing Yarns.
I JOHN CORRIGAN of 11 Grafton Street, Chorlton-on-Medlock Manchester in the
County of Lancaster, Machinist, 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 the construction of what are known as "bundling-presses'
used for compressing yarns, my objects being to simplify such construction, to render
the action of the press noiseless, and to facilitate the unlocking and removal of the top
bars after the bundle has been compressed.
The nature of my invention will be readily understood on reference to the two
sheets of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on Sheet 1 of the drawings is a vertical section of a bundling press made
according to my invention and Fig. 2 is a front view of the same.
b
On sheet 2 of the drawings, Fig. 3 is an end view of the same; a is the main frame
of the apparatus, & the first motion shaft, c the table and d the follower, e are the front
plates, the back plates and the top plates of the press.
Instead of actuating the follower d by crank pins and connecting rods as usual
in this class of press provide it with a vertical rack beneath, gearing directly
into the pinion which is actuated by suitable compound gearing k from the first
motion shaft b. Upon this shaft I mount a ratchet wheel (see Fig. 2) provided
with a
pawl or catch m as usual but instead of allowing the said pawl or catcli
to remain continually in gear with the said wheel I provide it with a projection n
(or a tail piece) by which it is held away from the ratchet wheel by means of a
lever o (or otherwise) acted upon by any convenient moving part of the press, so
that when the bundle has been sufficiently compressed the pawl or catch mis
allowed, or caused, to fall into gear with the teeth of the ratchet wheel / and so
retain the follower d in its position. This renders the action of the press noiseless.
Many devices may be adapted for this purpose but I prefer to use the following
means as shown at Fig. 2 on the drawing.
I mount the light lever o aforesaid upon the frame of the machine, one end of
which lever is beneath the setting-on handle p and the other end beneath the pro-
jecting pin n on the ratchet pawl or catch m above named. Thus when the setting
on lever p is depressed to start the compression of a bundle it will depress one
end of the lever o raising its other end, and with it the pawl or catch m but as
soon as the compression is completed the stud dx (see Figs. 1 and 3) fixed on the
follower d, raises one end of the lever or catch 7, releasing the stop rod r and
allowing the setting-on lover p, (which is weighted at its other end) to rise and
release the catch lever o thereby allowing the pawl or catch m to fall into action
and retain the follower d in position. If preferred instead of using the projecting
pin n the end of the catch lever o may be cranked or so formed as to act beneath
the pawl or catch m itself.

page_text: I
may here remark that in the provisional Specification filed with my application
for Patent I described certain sliding bolts and hinged latches for facilitating the
unlocking and removal of the top plates g, but I have not found such bolts and
latches so useful in practise as I then believed them to be and therefore I do not
wish to lay any claim to such devices, as I find the following arrangement preferable
for the purpose.
I continue each top plate g, (see Fig. 3) beyond the hinge by which it is con-
nected with the back plate f of the machine and I provide this continuation g* with
a suitable counterbalance weights to facilitate the lifting of the said top plate g by
the attendant.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the samo is to be performed I declare that what I
claim is:-
First. The combination with the follower of a yarn bundling press of a rack
pinion and compound spur gearing for actuating the same substantially as shown and
described.
Secondly. I claim the combination with the ratchet motion of such presses of a
device substantially as shown and described for the purpose of automatically holding
up the pawl or catch out of gear with the teeth of the ratchet wheel until the bundle
has been sufficiently compressed, and
Thirdly. I claim the elongation of the end of such top plate beyond the hinge
in combination with a weight for the purpose of facilitating the raising of such
plates substantially as hereinbefore described and illustrated by the drawings
annexed.
Dated this 3rd day of April 1980.
