page_text: I, RUDOLF CONSTANTIN SUNDBERG, of Almedahl, by Gottenberg, in the Kingdom of
Sweden, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object improvements in machinery for hackling flax and
other textile fibres.
The working parts of the machine consist of endless, revolving, vertical hackle
sheets which operate on the opposite sides of the stricks of flax or fibre which
are placed between them. These hackling sheets are made to approach and recede
from one another at the top in the following manner. The upper pair of rollers by
which they are supported are carried by oscillating arms mounted in sockets in the
frame of the machine. The upper ends of these arms are connected with shafts on
each side of the machine and these shafts receive a rocking motion through straps
fastened to pulleys on them and to a counterbalanced lever operated by a cam on a
cam shaft driven from the main shaft of the machine. In order to provide for
varying degrees of motion of the hackle sheets, the sockets of the oscillating arms
can be adjusted and adjustable stops are also provided on the rocking shafts.
The strick holders are fed lengthwise of the machine in a channel in the usual
manner by clutches on a shifting rod. This shifting rod is operated in the
following way-about the middle of the machine a toothed quadrant is keyed to
one of the rocking shafts and engages with a pinion on a spindle carried by a
bracket on the frame. The rotation of this spindle is conveyed by bevel gearing
to a pinion engaging with a rack on the shifting rod so that each time the hackle
sheets are separated and brought together again the shifting rod is moved forwards
and back again and the strick holders are moved on one stage.
Motion is conveyed from one end of the machine to the other by the shaft of one
of the brush rollers which is driven by gearing from the shaft of the main driving
pulley. This gearing may be adjustable as may also be that driving the cam shaft
of the counterbalanced lever to allow of working at different speeds.
From the shaft, of the brush roller motion is conveyed to the other brush roller and
to the lower rollers carrying the hackle sheets and thence to the doffing rollers.
Means are provided for altering the position of the brush rollers, the doffing rollers
and also the doffing knives. These last are operated by rods worked by an eccentric
on a stud axis carried by an adjustable bracket, the eccentric being driven by toothed
gearing.

page_text: I, RUDOLF CONSTANTIN SUNDBERG, of Almedahl by Gottenberg, in the Kingdom
of Sweden, Civil 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 :-
This invention has for its object improvements in machinery for hackling flax and
other textile fibres.
The working parts of the machine consist of endless, revolving, vertical hackle
sheets which operate on the opposite sides of the stricks of flax or fibre which are
placed between them.
These hackling sheets are made to approach and recede from one another at the
top in the manner hereinafter described.
In the accompanying three Sheets of Drawings Figures 1 and 2 are end elevations
and Figure 3 is a side elevation of a hackling machine made according to my
Invention.
The numerals 1 and 2 indicate the endless travelling hackle sheets suppported at
the top on a pair of rollers 3, and at the bottom on rollers 4 and 5. Each roller 3 is
carried in an oscillating arm 6 supported in a socket 7 carried by the frame 8 of the
machine. The upper ends of the arms 6 are respectively connected by links 9 with
arms 10 fixed on rocking shafts 11 on opposite sides of the machine and these
shafts 11 receive a rocking motion by the following or any other suitable
means:
On the shafts 11, are secured a pair of pulleys 12 over which pass a pair of
straps or chains 13 connected to a counter balanced lever 14 fulcrumed at 15 to
the frame 8 and operated by a cam 16 on a cam shaft 17 which is driven by a
train of gears 18, 19, 20, 21, 22, 23, from the main shaft 24 which is driven by
a belt, not shown, and a pair of fast and loose pulleys 25. When the belt is on the
fast pulley 25 motion is transmitted from the driving shaft 24 through the train of
gears to the cam shaft 17 and as the cam 16 depresses the lever 14 the latter draws
down the straps 13 which turn the pulleys 12 and shafts 11 and by the links 9 move
the arms 6 with the hackle sheets 1, 2, away from one another but as the cam 16
turns away from the lever 14 the weight thereon assisted by weights, not shown,
attached to the free ends of the straps 13 raises the end of the lever and so turns the
pulleys 12 and shaft 11 in the opposite direction and by the links 9 moves
the arms 6 with the hackle sheets 1, 2, toward one another.
In order to provide for varying degrees of motion of the hackle sheets 1, 2, the
sockets 7 of the oscillating arms 6 can be adjusted by means of the bolts '27 and
regulating screws 28 and adjustable stops 29 are also provided on the arms 10 of the
rocking shafts 11.
The strick holders, not shown, are fed lengthwise of the machine in a channel 30
in the usual manner by clutches on a shifting rod 32. This shifting rod 32 is
operated in the following way:-About the middle of the machine a toothed
quadrant 33 is keyed to one of the rocking shafts 10 and engages with a pinion 34 on
a spindle 35 carried by a bracket on the frame 8. The rotation of this spindle 35
is conveyed by bevel gears 36, 37, to a spindle 38 on which is secured a pinion 39
gearing with a rack 40 on the shifting rod 32 so that each time the hackle sheets
are separated and brought together again as described the shifting rod 32 is moved
forwards and back again and the strick holders are moved on one stage. Motion is
conveyed from one end of the machine to the other by the shaft 41 of one of the
brush rollers 42 which is driven by gears 43 and 44 from a spur wheel 45 on the

page_text: driving shaft 24. This gearing may be changeable as may also be that for driving
the cam shaft 17 to allow of working at different speeds.
From the shaft 41 of the brush roller 42 motion is conveyed to the other brush
roller 46 by gears 47, 48, 49, and 50, and the lower rollers 4 and 5 carrying the
hackle sheets are driven respectively from the gear 47 by a spur wheel 51 and by the
train of gears 48, 49, 50 and 52. The doffing roller axles 56, 57, are driven from
pinions 58, 59, on the axles of the bottom rollers 4 and 5, the roller axle 56 being
driven from the pinion 58 by the gears 60, 61, 62, and the roller axle 57 from the
pinion 59 by the gears 63, 64, 65. Adjusting screws and other means as shown are
provided for altering the position of the brush rollers 42, 46, the doffing roller
axles 66, 67, and also the axles of the doffing knives 66 and 67. The doffing knife
axles 56 and 57 are operated by connecting rods 68 worked by an eccentric strap 69
and eccentric 70 mounted on a stud 71 carried by an adjustable bracket 72, the
eccentric 70 being driven by a pinion 73 from the spur wheel 48.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. Mounting the endless vertically revolving or travelling hackle sheets in
oscillating arms in such manner that the upper ends of the hackle sheets are
caused to alternately approach and recede from one another substantially as herein
set forth.
2. In combination, the endless vertically travelling hackle sheets, the oscillating
arins for supporting the upper ends of the same, the quadrant 33 and the gearing
shown or equivalent means for actuating the shifting rod 32 by which the strick
holders are fed step by step through the channel 30.
3. The general combination and arrangement of parts substantially as herein
described and as illustrated by the accompanying Drawings.
