Improvements in Machinery for Bundling and Tying Bundles
of Chips.
We, THOMAS PICKUP of 51, Springfield Road, Burnley, in the County of
Lancaster, Grocer, JAMES SPENCER of Cow Lane, Burnley aforesaid, Mechanician,
and ROBERT WEBSTER of Oxford Road, Burnley aforesaid, Grocer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to machinery for bundling and tying bundles of chips, and
consists essentially in so constructing the machine that it performs the functions of
bundling and tying with little, if any, assistance on the part of the attendant.
A revolving disc provided with one, two or more recesses, preferably circular in
shape, gathers the chips as one of the said recesses passes a trough proceeding from the
chopping or splitting machine, each recess being sufficiently large for one bundle.
A stationary plate is fixed near the former and provided with a flange to retain the
chips in position in the recess.
The partially formed bundle is now carried by the revolving disc until it comes
in close proximity to the eye of a stationary or moving needle, carrying the end of
a wire with a kink in it (to prevent the end slipping from the eye of the needle)
and proceeding continuously from a reel. At this moment, by the aid of suitably
timed machinery, a clip, shaped like an inverted V carried at the end of a cranked
shaft, seizes the kinked end of the wire, and by an intermittent rotary motion given
to the cranked shaft wraps the wire round the bundle of chips until it reaches the
eye of the needle again. Here the cranked shaft is elevated slightly by means of a
worm to clear the needle, and after having been crossed, the wire is held by a pair
of grippers suitably timed to seize the wire at this point. The jaws of the grippers
are opened for the reception of the ends of the crossed wire by the compression of
a spring and by forcing the jaws outwards, against the action of the spring, through
a cylindrical cover. A catch falling into a rack allows of the compression of the
spring to a certain point, when a projection disengages the catch, and the spring
being relieved, instantly resumes its normal position, the jaws of the gripper being
now closed firmly on the crossed ends of the wire.
A suitably timed cutter having a flange now descends, and severs the wire from
the rest on the reel, the flange of the cutter making a kink to prevent the loose end
of the wire slipping through the eye of the needle.
A rotary motion is now given to the grippers, which twist or tie the wire and
complete the bundle.
This operation having been effected, an intermittent rotary motion in a reverse
direction is given to the cranked shaft, so as to regain its proper position in
proximity to the needle.
The bundle of chips having now been completed and tied is carried forward by
the motion of the revolving disc until it reaches a hole in the revolving plate,
through which it drops, and is ready to be packed for delivery.

Improvements in Machinery for Bundling and Tying Bundles
of Chips.
We, THOMAS PICKUP of 51, Springfield Road, Burnley, in the County of
Lancaster, Grocer, JAMES SPENCER of Cow Lane, Burnley aforesaid, Mechanician,
and ROBERT WEBSTER of Oxford Road, Burnley aforesaid, Grocer, 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 machinery for bundling and tying bundles of chips, and
consists essentially in so constructing the machine that it performs the functions of.
bundling and tying with little, if any, assistance on the part of the attendant.
A revolving dise provided with one, two or more recesses, preferably circular in
shape, gathers the chips as one of the said recesses passes a trough proceeding from
the chopping or splitting machine, each recess being sufficiently large for one
bundle. A stationary plate is fixed near the former, and provided with a flange
to retain the chips in position in the recess.
The partially formed bundle is now carried by the revolving disc until it comes
in close proximity to the eye of a stationary or moving needle, carrying the end
of a wire with a kink in it (to prevent the end slipping from the eye of the needle)
and proceeding continuously from a recl. At this moment, by the aid of suitably
timed machinery, a clip, shaped like an inverted V carried at the end of a cranked
shaft, seizes the kinked end of the wire, and by an intermittant rotary motion
given to the cranked shaft wraps the wire round the bundle of chips until it
reaches the eye of the needle again. Here the cranked shaft is elevated slightly
by means of a worm to clear the needle, and after having been crossed, the wire
is held by a pair of grippers suitably timed to seize the wire at this point. The
jaws of the grippers are opened for the reception of the ends of the crossed wire
by the compression of a spring and by forcing the jaws outwards, against the
action of the spring, through a cylindrical cover. A catch falling into a rack
allows of the compression of the spring to a certain point, when a projection
disengages the catch, and the spring being relieved, instantly resumes its normal
position, the jaws of the grippers being now closed firmly on the crossed ends of
the wire.
A suitably timed cutter having a flange now descends, and severs the wire from
the rest on the reel, the flange of the cutter making a kink to prevent the loose
end of the wire slipping through the eye of the needle.
A rotary motion is now given to the grippers, which twist or tye the wire and
complete the bundle. This operation having been effected, an intermittant rotary
motion in a reverse direction is given to the cranked shaft, so as to regain its
proper position in proximity to the needle.
The bundle of chips having now been completed, and tied is carried forward by
the motion of the revolving disc until it reaches a hole in the stationary plate,
through which it drops, and is ready to be packed for delivery.
f
In the accompanying drawings,
Fig. 1 is a side elevation and Fig. 2 a plan of our improved machine for
bundling and tying bundles of chips.
Referring to Fig. 2, A is a trough, which feeds the chips into the machine from
the chopper, the chips being conveyed by a suitable conveyor or simply allowed to
be automatically fed by a continuous supply of fresh chips from the chopping
machine. The chips enter the flanged recesses B', B' B' and B' of the disc C, to
which an intermittant rotary motion equal to about a quarter of a revolution is
given by the shaft C' as is hereinafter more fully explained. Fixed to the shaft C¹
is an eccentric C³, which bears on said flanged recesses as they are nearing the

page_text: tying device, thus firmly tightening the bundle of chips in position, the flanges of
the recesses momentarily yielding to the pressure put upon them.. The said disc C
moves in the flanged stationary plate C³."
As seen in Fig. 1,, the respective motions of the machine are derived from main
driving wheel D, which sets in motion heart-shaped cam D¹ and pulley D³, all
mounted on shaft D³. The cam D₁ gives a reciprocating motion to rocking
lever E, mounted on stud E¹ on the bracket E, and thereby transmits a backward
and forward movement to the sliding bar or rail F, operating the mechanism for
lapping the tying wire round and partly completing the bundle.
Before proceeding to describe the tying mechanism, we will describe how an
intermittant rotary motion is imparted to the shaft C¹ for effecting the delivery of
the chips. This is clearly illustrated in Figs. 1 and 3, in which is shewn the slip
catch & mounted at the far extremity of the sliding rail F, and capable of slipping
over the star wheel H on shaft C' when moved in a backward direction, but when
moved in a forward direction the catch piece G bears against the top of sliding
rail F, and coming in contact with the star wheel moves it a tooth forward and
consequently the disc C a quarter of a revolution.
.
We will now describe the bundling and tying mechanism. On the said sliding
rail F is also a pin I, which gives a rocking motion to the arm I' and shaft I". On
shaft Is is toothed wheel J gearing into pinion J' carried by shaft K supported by.
a stout upright K₁ from the body of the machine. The shaft K has at its lowest
extremity cranked arm K2 (seen in Fig. 1 and detached view Fig. 4).
The tying wire L proceeds continuously from a reel L', and its end is pushed
through a hole in the L bracket M', the upper portion of which is formed with
teeth M. The cranked arm K' has a hook K³ at its extreme end, and carries a
small pinion N mounted on a stud, to which is also fixed a small segmental block N¹,
so that both the pinion and block will revolve together.
Commencing from the L bracket. M' the hook K³ on the cranked arm K' seizes
the loose end of the wire L, and the pinion N gearing in the rack M' in its motion
causes the segmental block N' also to revolve and strike the end of the wire L
kinking it and holding it firmly. The crank arm K2 deriving its motion from the
sliding bar F completely laps the tying wire round the bundle of chips. But in
its movement, however, the shaft K is slightly elevated by the worm O, the spiral
of which moves on the pin O', so as to raise the pinion N out of contact with
and allow it to pass the rack M and the jaws of the grippers P about to be
explained.
Just as the crank arm K' has passed the jaws of the grippers a second time, the
rocking lever E imparts motion to the shafts S₁ sliding in the frame Q¹. The
shafts S¹ now force the sliding piece Q forward on the shaft T, which is formed
at one end into the lower jaw of the grippers. By this motion, the connecting
link R on the sliding piece acts upon another link R', provided with a slot R³,
which works on a stud fixed about midway of the upper jaw P of the grippers.
The upper jaw P of the grippers is thus brought firmly down upon the crossed
ends of the wire; and being provided with flanged sides P¹, which come below
the upper edge of the lower jaw of the grippers, acts like a pair of shears, com-
pletely severing the ends of the wire and at the same time holding them firmly.
Additional leverage and extra grip are obtained by the slot R² of the connecting
link R sliding forward on its stud, thus partaking partly of the nature of an
inclined plane, and also shortening the distance between the said connecting link R¹
and its fulcrum.
Simultaneously with this movement, the sliding piece S carried by the side
shafts S engages the toothed clutch piece S' keyed on the shaft T with the crown
wheel S loosely mounted on the said shaft T, and driven by driving cord or belt U,
from carrier pulley V, to which motion is continuously transmitted by driving belt
or cord V. An intermittent rotary motion is thus given to the shaft T and the
grippers P, which thereby twist the ends of the wire tightly round the now completed
bundle of chips.

page_text: The spiral spring W, which has during this motion been distended, now resumes
its normal position, thereby drawing back the slide piece Q³, and reopening the
jaws of the grippers.
The next stroke of the slide bar F moves the star wheel H (Fig. 3) another
tooth forward, bringing the completed bundle from a position B³ to B, when it
then drops through a hole in the stationary plate C, ready to be packed for delivery,
whilst by the same movement another bundle of chips is brought in position to be
acted upon by the bundling and tying mechanism.
We would observe in conclusion that we do not confine ourselves to the particular
driving parts D', S', U, V and V₁ as it will be evident that various other driving
arrangements or gear wheels may be employed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The bundling and tying machine, and arrangements of mechanism, substan-
tially as described and illustrated in Figs. 1, 2, 3 and 4.
2. The wiring of bundles of chips from a continuous reel, and means for lapping
the wire round the bundle, substantially as described, and illustrated in Figs. 1, 3
aud 4.
3. The arrangement of mechanism for gripping the crossed ends of the wire,
cutting and twisting the same, substantially as described and illustrated in Figs. 1
and 2.
4. The means for receiving and delivering the chips from the chopping or
splitting machine, substantially as described, and illustrated in Figs. 1 and 2.
