Improvements in Machinery for Drilling Fallers and Hackle Gills.
I FAIRFAX ODDY 39 College Road Bradford in the County of York Engineer do
hereby declare the nature of this invention to be as follows:-
My improvements relates to Machinery for drilling the pin holes in Fallers and
Gills used in the preparation and Combing of wool, silk, flax, ect.-My object being
to accomplish either automatically or by Hand the drilling of the pin holes in a much
cheaper and expeditious manner than hitherto-to effect this I construct the drilling
Machine with two drill Spindles parallel to each other but at different Elevations
constructed so as to drill two Fallers or Gills at a time-the two Spindles which
may be driven by a single or seperate Bands I connect so that they shall be fed up
to and withdrawn from their work simultaneously either by the ordinary Hand Lever
or automatically.
When feeding and withdrawing the drills automatically I provide means whereby
the time or interval during which the drills are withdrawn and witheld from their
Work for clearing out the cuttings is considerably reduced. To effect this I employ a
Cylindrical Cam so constructed that its shaft or Spindle shall revolve parallel with
but underneath the back ends of the drill spindles. At the periphery of this cam I
provide a projection so constructed that it shall operate against a pulley suitably
fixed to a Slide connecting the drill Spindles which at intervals withdraws the drills
from their work.
The Shaft or Spindle which supports the Cylindrical Cam may by the employment
of Counter Shaft and suitable Spur Gearing be driven from any convenient place.
The cross Slide which holds or supports the Fallers or Gills whilst being drilled I
construct so that it shall hold or support one over the other two Fallers or Gills at a
time-suitable provision being made for distancing the centres of the Fallers or Gills

page_text: so that they shall correspond vertically with the centres of the drill Spindles. Under-
neath and parallel with the cross slide I employ a Shaft or Spindle to which I secure
a division Wheel equally divided into a convenient number of teeth or Notches-
suitable connections being so arranged that a catch or pall shall when the drills have
drilled through the Fallers or Gills fall into the next tooth or Notch.
And by the operation of the Cylindrical Cam moving back the Slide that withdraws
the drill Spindles and the connection between the Screw which moves the cross
Slide which holds or supports the Fallers or Gills partially turn the Shaft or Spindle
under the cross Slide a distance that shall move the cross Slide equal to the pitch or
distance of the pin holes in the Fallers or Gills.

Improvements in Machinery for Drilling Fallers and Hackle Gills.
1 FAIRFAX ODDY 39 College Road Bradford in the County of York 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 :-
My improvements relates to machinery for drilling the pin holes in Fallers and
Gills used in the preparation and combing of Wool, Silk, Flax, ect.
My object being to accomplish either automatically or by hand the drilling of the
pin holes in a much cheaper and expeditious manner than hitherto.
To effect this I construct the drilling machine with two drill Spindles parallel to
each other but at different elevations constructed so as to drill two Fallers or Gills at
a time-the two Spindles which may be driven by a single or seperate bands I
connect so that they shall be fed up to and withdrawn from their work simultaneously
either by the ordinary hand Lever or automatically. When feeding and withdrawing
the drills automatically I provide means whereby the time or interval during which
the drills are withdrawn and witheld from their work for clearing out the cuttings is
considerably reduced. To effect this I employ a Cylindrical Cam so constructed that
its Shaft or Spindle shall revolve parallel with but underneath the back end of the
drill Spindles.
At the periphery of this cam I provide a projection so constructed that
it shall operate against a pulloy suitably fixed to a Slide connecting the drill Spindles
which at intervals withdraws the drills from their work-the Shaft or Spindle which
supports the cylindrical cam may by the employment of Counter Shaft and suitable
spur gearing be driven from any convenient place the cross Slide which holds or
supports the Fallers or Gills whilst being drilled I construct so that it shall hold or
support one over the other two Fallers or Gills at a time—suitable provision being
made for distancing the centres of the Fallers or Gills so that they shall correspond
vertically with the centres of the drill spindles. Underneath and parallel with the cross
Slide I employ a Shaft or Spindle to which I secure a division Wheel equally divided
into a convenient number of teeth or Notches-suitable connections being so arranged
that a catch or pawl shall when the drills have drilled through the Fallers or Gills
fall into the next tooth or notch-and by the operation of the cylindrical cam moving
back the slide that withdraws the drill spindles and the connection between the Screw
which moves the cross slide which holds or supports the Fallers or Gills partially
turn the Shaft or Spindle under the cross Slide a distance that shall move the cross
slide equal to the pitch or distance of the pin holes in the Fallers or Gills.
In order that my Invention may be better understood I have annexed 2 Sheets of
drawings. Fig. 1 is side elevation of my machine. Fig. 2 back end view of the
headstock in which the two drill Spindles revolve. Fig. 3 is enlarged plan of
Cylindrical Cam and pulley.
When feeding the drills automatically the pulleys A may be driven from an
ordinary counter shaft thereby transmitting motion through the Spur Wheels B.

page_text: Shaft C. cam D. and thence to the pulley E. and Slide F (to which the pulley E is
secured by a stud or pin.) thereby withdrawing both the drill Spindles G, G, back on
each revolution of cam D. the drills being fed up to their work by the Weights and
Levers, E¹ E and Slide F. and revolved by a band passing round the two
pulleys G' G'.
When the spindles have traversed a sufficient distance as to press the drills through
the Fallers H. H. (shown in section) the paw! I. will through the connection of the
Lever I and the connecting rod I and short Lever I drop into another notch of the
pawl Wheel 1 and on the projection of the cam D forcing back the pulley E. the
pawl Wheel I will be moved a tooth and by the connection of suitable change Wheels
with the Shaft I (to which is fixed the pawl Wheel I) and the Screw J. at the end
of the ordinary Saddle J¹ the Slide K. which holds the Fallers whilst being drilled will
be moved the exact pitch of one pin hole.
The Levers E' E' and I are all secured to the shaft E' which is free to oscillate in
the journal E*.
The pawl Lever being made to oscillate loose on the shaft I'.
By these means I secure a reliable and exact automatic picking motion, without
using any form of Springs.
On referring to enlarged plan of cam D. and pulley E. Fig. 3. it will be readily
understood that the time or interval during which the drills are withheld from their
work is of very short duration-it will also be seen from the end view of the head-
stock Fig. 2. that the drill spindles G. G. are in addition to being at different
elevations-spaced a distance apart so as to admit of a single band from an over-
head counter Shaft driving both Spindles at once.
Fig. 4. is enlarged plan of my machine showing how the two drill Spindles G. G.
are simultaneously fed up to and withdrawn from their work when drilling by hand-
the hand lever L. is supported on a Stud L and is free to move (either to the right
or left hand to the slide F. is secured another Stud L'against which the short end
of the Lever L operates-it will readily be seen that when the end of the Lever L. is
moved to the right hand that the other end L³ will press against the Stud L towards
the left hand and consequently move the Slide F and drill spindles G. G. towards
the Fallers H. H. whilst being drilled to withdraw the drill spindles from their
work the end of the Lever L. is moved to the left hand-to move the slide K. the
distance or pitch of the pin holes it is only necessary to move the ordinary hand
Lever pawl and picking wheel at the end of the Screw J a distance equal to the
desired pitch of the holes.
When the hand Lever L. is in operation it acts independantly of the motion
previously described which feeds and withdraws the drill spindles automatically.
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 construction and arrangement of the Spindles G. G. and Slide F. for
drilling two Fallers or Gills at one time either automatically or by hand.
2. The automatic picking motion comprising the cam D. and pulley E in combina-
tion with the Levers and shaft E' E' and 18.
3. The pawl I. in combination with the Levers I pawl Wheel and Shaft 1 and 1'
all for the purpose described.
