PROVISIONAL SPECIFICATION.
Improvements in Gill Drawing Heads and Hackling Machines.
J, JAMES BARBOUR, of Falls Foundry, Belfast, Machinist, do hereby declare
the nature of this invention to be as follows:-
This invention consists of improved means of operating, moving or reversing by
hand the gills, and is designed to provide increased facilities of access for cleaning
the gills of said machines, expediting such operation of inspecting, removal, and
replacement of any one of the series of fallers or hackles.
According to this my said invention, I employ a pinion and hand wheel, the
pinion gears with one of the wheels joining the train of wheels from the driving
pulley shaft to the hackle sheet shaft, and preferably the hand wheel is mounted
loosely on its stud, there being a locking pin or other like device whereby the said
wheel is made one with the pinion. A suitable device for purpose aforesaid
comprises a recess formed in the boss of the hand wheel, containing a spiral spring,
and a locking pin; one end of the pin is operated by the attendant on the machine,
so as to put the pin in and out of gear with the locking hole in the pinion. The
hand wheel and pinion can be made in one piece, and working loosely on its stud,
can be withdrawn out of the plane of gearing, and be thus disconnected. In gill
push bar drawing heads, the pinion is applied as above described to the train of
wheels leading to the carrier shaft, and is provided with hand wheel and locking
device as above described. Where screw fallers are employed, the connection of
the pinion is to the train of wheels, leading to the wheel on the faller screw
or worm.
The use of the devices as above described, enables the attendant at any time to
move forward by hand the hackles or gill bars step by step, or reverse such
movements so as to bring any one or the whole series of hackles or gills in rotation
to position, convenient for inspection, cleaning, removal for repair, or otherwise, any
one or more of the hackles or gills.

COMPLETE SPECIFICATION.
Improvements in Gill Drawing Heads and Hackling Machines.
I JAMES BARBOUR of Falls Foundry, Belfast, Co. Down Ireland, 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 consists of improved means of operating, moving, or reversing by
band the gills, and is designed to provide increased facilities of access for cleaning
the gills of said machines, expediting such operation, and allowing of ready
inspection, removal, and replacement of any one of the series of fallers, or
hackles.
According to this invention I employ a pinion, and hand wheel; the pinion
gears with one of the wheels joining the train of wheels from the driving pulley
shaft to the hackle wheel shaft, and preferably the hand wheel is mounted loosely

page_text: on its stud, there being a locking pin or other like device whereby the said wheel
is made one with the pinion.
A suitable device for purpose aforesaid comprises a recess, formed in the boss of
the hand wheel, containing a spiral spring and a locking pin; one end of the pin is
operated by the attendant on the machine so as to put the pin in and out of gear
with the locking hole in the pinion.
The hand wheel, and pinion can be made in one piece, and working loosely on its
stud can be withdrawn out of the plane of gearing, and be thus disconnected. In
gill push bar drawing heads, the pinion is applied as above described to the train of
wheels leading to the carrier shaft, and is provided with hand wheel, and locking
device as above described.
Where screw fallers are employed the connection of the pinion is to the train of
wheels leading to the wheel on the faller screw or worm.
The use of the devices above described enables the attendant at any time to
move forward by hand the hackles or gill bars step, by step, or reverse such
movements so as to bring any one or the whole series of hackles or gills in rotation
to position convenient for inspection cleaning removal for repair or otherwise any
one or more of the hackles or gills.
Such being the nature and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings in
which-
Fig. 1 is an elevation of as much of a hackling machine as will shew the nature
of my invention.
Fig. 2 is an elevation of as much of a push bar drawing frame as will shew the
nature of my invention.
Fig. 3 is an end view and section of the hand wheel and pinion showing the
locking pin arrangement.
In Fig. 1 the pinion G which is capable of being locked to the hand wheel H
gears into the wheel A which is on the pulley or driving shaft, this wheel A drives
the hackle sheet L to which the hackles M, are fixed through the train of gearing
made up of the wheels B, C, D, E and F.
In Fig. 2 the pinion 1 on the driving shaft through the train of gearing
consisting of the wheels 2, 3, 4, 5, 6, 8 and 9 drives the fallers 10, the pinion
which is capable of being locked to the hand wheel H being driven by the
wheel 2.
In Fig. 3 which is an enlarged view of the pinion G and hand wheel H, pinion G
and socket P are for the sake of convenience made in separate pieces the pinion G
being made fast to the socket P and work loosely on the stud Q, the hand wheel H
also being loose on the same stud Q but kept from moving endways by means of a
collar or pin X. In the boss of the hand wheel H a recess is formed containing
the spiral spring R and locking pin S which gears with the locking hole in the
pinion or socket P and thus locks the pinion and hand wheel together, the spring R
in the recessed chamber of the hand wheel keeps the head of the locking pin in gear
with the locking hole of the socket.
The locking pin can be withdrawn from the locking hole of the socket by the
attendant, and is prevented from returning to the locking hole of the socket by
means of the pin T in the locking pin S, the pin T working in a slot U, the
attendant when he finds the pin T clear of the slot U gives the locking pin S a
turn so that the pin T is prevented from returning and thus the locking pin S is
kept clear of the locking hole of the socket when it is desired to put the locking
pin S in gear the attendant turns the pin S until the small pin T is in line with the
slot U the spring R then comes into action and puts the locking pin S into the
locking hole of the pinion or socket.
The hand wheel is usually kept out of gear when the machines are at work.
By the use of this device the attendant is thus able when the machines are at
rest by merely putting the hand wheel H in gear with the pinion G and turning it
by hand or otherwise, the hackles or gills of the said machines can by means of the

page_text: trains of gearing as already described be brought into any suitable position for
examination, removement or replacement of any of the fallers or hackles.
Having now particularly described and ascertained the nature and object of my
said invention, and in what manner the same is to be performed I declare that what
I claim is :-
1. In gill bar drawing frames and hackling machines the use of a hand wheel and
a pinion provided with locking and releasing device such as set forth and a train of
gearing all in combination for purpose herein fully described.
