Improvements in Machines for Breaking, Scutching, and Cleaning
Flax, Jute, Hemp, and similar Fibres.
I JOHN ORR WALLACE, 113 Wellesley Avenue, Lisburn Road Belfast, Broker do
hereby declare the nature of this invention to be as follows:-
The object of the present invention is to further improve my patented machine
No. 193, of 1887 for Breaking Sentching and Cleaning Flax, Jute, Hemp and similar
Fibres; and to adapt it to perform its operations on a part or parts of the length of
the beet or bunch of fibre introduced into it as required by some industries and this
at a greater speed than heretofore. In effecting this I dispense with my retaining
rollers and alter the construction of my machine in such a manner that I can substitute
for them an endless apron travelling above the rows of my piercing tools in a plane,
horizontally, or inclined to that occupied by their points. The bundle of fibre
under operation is carried by studs fastened to the apron across the machine and the
end or ends to be treated hang between the opposed rows of pins and are pierced
by them in transit. I impart to the endless apron the intermittent motion, which
my rollers in previous patent machine possessed indispensable to the economical
and efficient treatment of the fibre, either as before by ratchet wheel and pawls
or by a cam suitably mounted and driven by main, crank, or other convenient
shaft and connected to that giving motion to endless apron by a worm wheel,
levers or other device. What I mean by an intermittent motion or feed imparted
to the fibre passing through the machine is, that while the piercing tools are
penetrating and retiring through the fibre, the feed of fibre shall be motionless,
passing on only when pin points are completely clear of it.
purpose to employ the ordinary holders and channels used in heckling
machines when I find their use more convenient, instead of the above described
endless apron, causing the holders however to travel through the machine, only
when each succeeding stroke of piercing tools shall have brought the pin points out
of and entirely clear of the fibre held by the holders.

Improvements in Machines for Breaking, Scutching, and Cleaning
Flax, Jute, Hemp, and similar Fibres.
I, JOHN ORR WALLACE, 113 Wellesley Avenue Lisburn Road, Belfast, Broker
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:-
The object of the present invention is to further improve my patented machine,
No. 193 of 1887, for Breaking Scutching and Cleaning Flax, Jute, Hemp and similar
Fibres; and to adapt it to perform its operations on a part or parts of the length of
the beet or bunch of fibre introduced into it as required by some industries, and this
at a greater speed than heretofore. In effecting this I dispense with my retaining
rollers and alter the construction of my machine in such a manner that I can substitute
for them an endless apron travelling above the rows of my piercing tools in a plane,
horizontal or inclined to that occupied by their points. The bundle of fibre under
operation is carried by studs fastened to the apron across the machine, and the end
or ends to be treated hang between the opposed rows of pins and are pierced by them
in transit. I impart to the endless apron the intermittent motion which my rollers

treatment of the fibre, either as before by ratchet wheel and pawls or by a cam
suitably mounted and driven by main crank, or other convenient shaft, and connected
to that giving motion to endless apron by a worm wheel, levers, or other device.
What I mean by an intermittent motion or feed imparted to the fibre passing through
the machine is, that while the piercing tools are penetrating and retiring through the.
fibre, the feed of fibre shall be motionless, passing on only when the pin points are
completely clear of it. I purpose to employ the ordinary holders and channels used
in heckling machines when I find their use more convenient, instead of the above
described endless apron, causing the holders however to travel through the machine
only when each succeeding stroke of piercing tools shall have brought the pin points
out, and entirely clear of the fibre held by the holders.
Referring to the accompanying drawings A is an elevation, and B a plan of so
much of my improved machine as will make clear the nature of my invention.
Referring to figure A, 1. 1. are the crank shafts which impart a to and fro motion to
the pinning tool carriages 2. 2., 3. 3. are the piercing pins mounted on these and
travelling through perforations in the shields 4. 4., 5 is a shaft upon which the
drums 6 are keyed provided with endless belts or aprons furnished with studs or
spikes to carry the fibre across the table of the machine. Intermittent motion is
imparted to shaft 5 from crank shaft 1 or other convenient point by any of the well
known devices.
Referring to figure B, the same figures denote the same parts. 3. 3. are the
piercing pins 4. 4. are the shields; 5 the shaft imparting motion to transverse
travelling sheets or bands furnished with pullies 6.; 7 is the fibre under treatment.
It will be seen that shaft 5 having intermittent motion conveyed to it will transmit
this motion to the sheets furnished with spikes carrying the fibre. The operation of
the machine is as follows; the fibre is laid horizontally on the transverse travelling
bands, the end of it to be operated upon by piercing tools hanging down between
their opposed rows as the bands travel forward the fibre is carried with them by means
of the studs or spikes across the machine, being all the time of its transit under
operation of the pins until it is delivered scutched at the further side of the machine.
Instead of this method of conveying fibre across the machine I also purpose to
employ the ordinary construction of holders and channels employed in heckling
machines when I find it necessary, imparting however to the holders by any of the
well known means the intermittent motion already described as applied to my
travelling bands or belts.
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. The use of a machine furnished with piercing tools travelling through perforated
shields provided with transverse travelling endless belts or aprons to which intermittent
motion is given.
2. The use of a machine as above described having holders, driven along channels,
to which intermittent motion is imparted instead of transverse travelling endless
belts or aprons.
