PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Drilling Fallers.
We, HENRY HAIGH, ROBERT WALKER, and JOSEPH MITCHELL, all of
Victoria Wool Comb Works, Dalton Lane, Keighley, in the County of York,
Wool Comb Makers, do hereby declare the nature of this invention to be as follows:-
Our machine consists of a suitable cast iron bed, carrying an upright and cross
slide to hold the fallers, which is adjusted by means of a nut and screw. The head
carrying the spindle for drilling, (which is placed at one end of the bed), has
bolted to it a box which is arranged with suitable motions for drilling fallers, and
for feeding automatically. A. disc and pin worked by means of worm and worm
wheel, actuates a quick return arm or lever, pivotted to the bed end, for with-
drawing the drill at intervals to allow the cuttings to get away. A catch
adjustable in a slot running the whole length of the box, can be arranged to drop.
down when the drill has got through its work, and so withdraw a second catch,
which forms the lock for the slide bar; this slide bar is the means for giving
feed to the cross slide carrying the fallers, for as soon as the slide bar is released,
it is brought into such a position that in the return stroke of the drill spindle, it
is drawn back by a pin projecting from the box or spindle end; a pin in the slide
bar then comes in contact with and draws back a second lever, which actuates a
horizontal rod sliding in bearings on the bed side, giving motion to suitable levers
and ratchets fixed on the end of the cross slide. The slide bar is brought back
into proper position for feeding by means of a spring which is always in tension.
A hand lever is also provided so that the machine can be worked by hand when
required.
▸
The spindle when working automatically is fed up by means of a spring which
is always in tension, and can be easily removed when not required.
Dated this Twenty-fourth day of March 1890.

Improvements in Apparatus for Drilling Fallers.
We, HENRY HAIGH, ROBERT WALKER, and JOSEPH MITCHELL, all of
Victoria Wool Comb Works, Dalton Lane, Keighley, in the County of York,
Wool Comb Makers, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained

Cl

page_text: Working preferably within the box F is a disc F¹ and pin F', this disc and pin
being actuated by elliptical wheels G and H, receiving their motion from spur and
gear wheels F, F, F and F; these elliptical gear wheels G and H give a quick
return motion to a slide J by means of a return arm or lever J¹ operated by the
said disc F and pin F.
As the disc revolves, it actuates the arm or lever J' which by reason of the
drill spindle E being attached to the slide at J', feeds or withdraws the drill
at intervals.
After the drill has got through its work a projection or stud J'
upon the slide comes in contact with a spring catch J pushing back the spring J',
and releasing the slide bar E, which is kept in tension by the spring K, the
slide bar E on being released (the drill having got through its work) operates &
pivotted lever K, which in turn by means of levers and rod K' and K', operates a
horizontal rod K, giving motion (by means of levers L') to a ratchet and ratchet
wheel L, attached to one end of the cross slide, this ratchet and ratchet wheel
operates a screwed rod or shaft L³, moving the slide C and faller into position for
the next hole to be drilled in the said faller, this operation is affected upon each
revolution of the disc F' and continued until sufficient holes have been drilled in
the faller.
The slide bar E and drill is brought into position for the next feed by means
of an eccentric swivel E³.
For feeding the drill automatically we employ a weight K' connected by band
or chain K to the slide J.
Attached and adjustable upon the slide C, are dogs or projections M fixed in any
desired position, so that when sufficient holes have been drilled in the faller, the
dog M comes in contact with a spring catch N, depressing same and releasing a
clutch P, operated by lever R and spring S, thus throwing the horizontal rod K'
out of gear, so preventing further movement of the slide; the lever K when not
engaged with clutch P, is loose upon the rod K³.
The machine is speeded by means of step cones G' and H' driven from the main
or other shaft.
We employ a small pump T operated from the driving shaft and which by
means of pipes T' and small nozzle T' propels a small jet of any suitable liquid
upon the faller for facilitating the drilling of same, the liquid
trough T³.
placed within
Or the spur and bevel wheels (for driving the disc F', and eliptical
wheels G and H) may be dispensed with, and worm and worm wheel employed.
Also for releasing the spring of the slide bar E a catch upon the slide bar
operating a swivelled stud or eccentric may be employed see Figs. 4 and 5.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we declare that what we
claim is :-
1. In drilling fallers, the use and employment of vertical and cross slides B and C,
slide bar E, disc F¹ and pin F2, eliptical wheels G and H, pivotted quick returning
arm or lever J', pivotted lever K, rods K' and K, horizontal rod K³, screwed rod
or shaft L³, dogs M, spring catch N, and clutch P, operated in the manner such as
shown and described.
2. In drilling fallers, the use and employment of vertical and cross slides B and C,
disc F, pin F, cliptical wheels G and H, slide bar E, dogs-M,-spring catch N
-and-clutch-Poperated in the manner such as shown and described.
3. In drilling fallers, the use and employment of vertical and cross slides B and C,
disc F', pin F, eliptical wheels G and H, and slide J, operated in the manner such
as shown and described.
4. The use and employment of the eliptical wheels G and H, disc F', pin F,
slide J, operated in the manner and for the purposes such as shown and described.
-5.-The use and employment of dogs M, spring catch N, and clutch P in the
manner and for the purposes such as shown and described.

page_text: 6. The general arrangement and construction of apparatus for drilling fallers
such as shown and described.
