Improvements in Screw Gillboxes and other like Machines
Employed in Preparing Wool and other Fibre.
I, JOB STAKE, of Oxford Road, Siddall, Halifax, Yorkshire, Mill Manager, do
hereby declare the nature of this invention to be as follows:-
:-
My invention has reference to the fallers employed in this class of machine, and
consists in the adoption of a new form of apparatus for receiving each faller as they
drop from the upper screw to the lower screw.
In carrying out my invention I employ a T headed bar capable of sliding up and
down in a box, or shell, such bar being held within its box by two opposing headed
bars placed horizontally, the heads of such bars being forced against the vertical bar
by spiral or other form of springs, the object of placing side pressure upon the rising
and falling bar being to retain the said bar in any position it has been lowered to
by the descending faller. When a faller is liberated by the upper screw and it
commences to descend, it is received by the head of the T headed bar, the weight of
the said faller forcing the bar softly down, thereby preventing sudden concussion, but
as soon as the said bar has been forced downward by the faller a revolving can
properly timed and shaped immediately comes into action and lifts up the said T
headed bar into its highest position so as to receive the next faller, and this goes on,
one after another, the said fallers forcing the bar downward and the cam lifting the
bar upward continuously.
For the purpose of more effectually deadening the sound of the faller when it drops
upon the upper surface of the T headed bar may be covered with leather or other
pliable substance.
In addition to the T headed bar for receiving the fallers as they descend from one
row of screws to the other, I employ at each end of the machine endless belts or
chains provided with lugs, the distance apart of which, will be equal to the depth
from one screw to the other, so that the full weight of the faller will not rest upon
the T headed bar, but will be borne also by the lugs on the endless chain.

page_text: The mechanism above described is enclosed in a suitably shaped box or casing, so
that loose particles of fibre cannot get onto it.
By the employment of apparatus as hercin described, the noise occasioned by fallers
dropping onto a dead surface from one screw to another is now removed, and the
breakages frequently happening to the fallers by the sudden stoppage thereof when
falling are also prevented, and the loosening of the gills in the fallers also occasioned
by the sudden dropping of the fallers will not now happen.
The apparatus is also of such a nature that it can be applied to existing machines
as well as to new ones.

I, JOB STAKE, of Oxford Road, Siddall, Halifax, Yorkshire, Mill Manager, 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:
My invention has reference to the fallers employed in this class of machine, and
consists in the adoption of a new form of apparatus for receiving each faller as they
drop from the upper screw to the lower screw.
In order that my invention may be better understood, I will now make reference to
the accompanying sheets of drawings illustrative thereof, wherein Fig. 1 is longitudinal
section of a screw gillbox employed in preparing wool and other fibre, and Fig. 2 is
end view thereof. a is the framework of the machine and the main driving shaft,
which by means of spur wheels e gives rotary motion to the bevel wheel d for driving
the bevel wheel e and consequently the lower or bottom screws f. On one of the
screw shafts f is fixed a spur wheel g driving the corresponding spur wheel and
screw shaft i. are fallers or bars carrying "heckle pins," the ends of such fallers
entering into the threads of the screws and , and are caused to travel in the
direction of the arrows in Fig. 1, for the purpose of lashing out, straightening, or
combing the fibre, which passes through two pairs of fluted feed rollers k, all of which
parts are arranged in the ordinary manner and form no part of my invention. As
previously stated, the object of my invention is to receive the fallers ; when they
reach the end of the screw i, so as to carry such fallers gently down to the bottom
screws without noise and concussion, and this I carry out by the employment of
the T headed bar 1, the vertical part of which enters into a suitably shaped box or
casing ; see enlarged front views Fig 3, section Fig. 4, taken through the lines 1
and 2 of Fig. 3, whilst Fig. 5 is plan view of the parts. The vertical part of the
Theaded bar enters the case m and it works up and down between two horizontal
headed bars n which are forced against the vertical bar by spiral spring o, the
pressure of which is sufficient to retain the bar in any position it has been lowered
to by the descending faller. Therefore, when a faller has reached the end of its
traverse in the upper screw it commences to descend and is received by the
horizontal part of the T headed bar 1, the weight of the said faller being sufficient
to force the bar softly down to its bottom position, ready to be received by the lower
screw ; and when this is done the T headed bar is lifted back again by a revolving
camp fixed on the shaft driven by spur wheels from a pinion on one of the lower
screw shafts as seen in Fig. 2. This revolving cam is timed and shaped so that
as soon as the T headed bar has carried the faller to its bottom position, the cam
comes into action and operates against the pin (see Figs. 3 and 4) projecting from
the T headed bar 1, whereby such cam lifts the said bar into its higher position again,
so as to be ready to receive the next faller, and this goes on, one after another,

page_text: the said fallers forcing the bar downward and the cam lifting the bar upward
continuously.
In this class of machine it is customary to employ a vertical finger similar to 1 in
Fig. 1 for the purpose of guiding the fallerš as they descend from the
upper screw to the lower one, and in practice I have found that when
a faller is descending from the upper to the lower screw, and it
arrives at the space between two screws, the finger 1, which is forced by the
spiral spring 2, carries or forces the faller into the open space, whilst at
the same time the upper end of the finger 1 strikes against the next succeeding faller,
causing noise thereby, and this is repeated every time each faller arrives at the end
of the upper screw ready for falling to the lower screw. In order to dispense with
the finger 1 I employ at each end of the machine endless chains or belts u provided
with lugs or projections e, the distance apart of such lugs being equal to the depth
from one screw to the other so that as the fallers are received at the top of the T
headed bar they are also received on the projecting lugs, which assist in carrying
the fallers down vertically from the upper to the lower screw without any noise,
consequently I now dispense with the vertical finger 1 which is now employed, and
the noise accompanying its use is avoided.
For the purpose of more effectually deadening the sound of the faller when it drops
upon the upper surface of the T headed bar such upper surface may be covered with
leather or other pliable substance.
By the employment of apparatus as herein described and illustrated, the noise
occasioned by gill fallers dropping onto a dead surface from one screw to another is
now removed, and the breakages frequently happening to the fallers by the sudden
stoppage thereof when dropping are also prevented, and the loosening of the pins in
gills or fallers also occasioned by the sudden dropping will not now happen.
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
--
Firstly. In screw gillboxes and other like machines the combination therewith of
a bar, which, as the fallers arrive at the end of the upper screw, automatically
receives and carries such fallers down to the screw, substantially as set forth and
described.
Secondly. In apparatus for receiving fallers and carrying them from the upper to
the lower screws, the combination therewith of spiral or other form of springs for
placing side pressure upon the carrying bar as illustrated and described.
Thirdly. In screw gillboxes, the combination therewith of the T headed bar 1,
horizontal bars n, springs o, and cam p, all arranged as described.
Fourthly. In screw gillboxes, the employment of the endless travelling chains or
belts u, with projecting lugs for receiving the fallers from one row of screws to the
other, for purposes and in manner substantially as described.
