Complete Accepted, 20th May, 1887.
I JOSEPH SWIFT of Beighton in the County of Derby Engineer do hereby declare
the nature of the said invention for "AN IMPROVED APPARATUS FOR BORING COAL ROCK
OR OTHER MINERAL SUBSTANCE," to be as follows:-
The object of this invention is to overcome the objections that have arisen to
coal boring or drilling machines as hitherto constructed, some of which machines
have been found to bend split or give at the bottom of the frame in which the borer
or drill works, and where the most strength should be, the defect arising when
weight is put on in the working.
My invention consists in making this boring apparatus or implement,-in some
parts known as a Miner's boring pillar,-for boring into coal rock or other mineral,-
with a strong solid metal frame and movable slide pillar, having a screw or worm
arranged or fitted in the bottom of the pillar to raise and lower the same.
On, or in, the top of the pillar is a slide so fitted and arranged as to slide up and
down the frame, a lock nut being suitably fitted to lock the slide at any required part
of the apparatus.
In connection with the same two carriers are provided which carry the screw that
forces the borer into the coal rock or other mineral; and they are arranged to slide
up and down the pillar so as to readily be made capable of boring wherever required.

An Improved Apparatus for Boring Coal, Rock, or other Mineral
Substance.
I JOSEPH SWIFT of Beighton in the County of Derby Engineer do hereby declare
tho naturo 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,
in writing and on reference to the accompanying sheet of drawings :-
This Invention relates to an improved apparatus for boring coal rock or other
mineral substance, which is constructed so as to be more efficient in working and
more reliable than the apparatus or machines heretofore used for the purpose; the
object of my invention being to overcome the objections to coal boring or drilling
machines as hitherto constructed, some of which machines have been found to bend
split or give at the bottom of the frame in which the borer or drill works and where
the most strength should be, the defect arising when weight is put on in the working
of the borer or drill.
This invention is equally applicable to boring or drilling machines or apparatus
whether they are made with a boring pillar or with other drill or boring appliance.
In order that my invention may be fully understood it is illustrated on the
accompanying sheet of drawings, on which Figure 1, is a front view of my boring
apparatus or implement, this description of apparatus being in some parts known
as a "Miner's boring pillar."-Figure 2, is a side view of the same; and Figure 3,
is a side view of the apparatus as at work. Figure 4, is a separate enlarged view
of the locknut or locking device.-Figure 5, shows the split nut of the carrier device;
and Figure 6, is an enlarged view of the couplings to hold and secure the screw and
borer or drill together. The same letters of reference indicate similar parts in
all the Figures.
My boring apparatus is constructed externally with a strong solid wrought iron
frame a, inside which a movable side or sliding pillar b, works up and down; this
pillar has a screw or worm c, fitted and working within the bottom end of it to raise
and lower the pillar by, the other end of the slide being formed so as, when in
operation, to and shut like a pair of eyes.
open
Fitted round (or in) the top of the apparatus is a slide or sliding piece d, which
is so made and arranged as to slide up and down outside the frame a, a locknut
or locking appliance e, shown separately at Figure 4, is fitted on, or to, each side
of the slide d, to lock and hold the slide d, at any required part of the apparatus ;
for effecting which locking purpose a series of holes 1, (or slots 2,-as shown in
Figures 3, and 4,-) are made, at about three inches apart, in each side of the frame a,
for the locknut or locking appliances of the sliding pillar b, and the slide d, to engage
or hold in. e¹, is the ratchet handle of the locknut appliance by operating which
handle the ratchet teeth of same are caused to hold in the holes or slots in the frame
of the apparatus.

page_text: In connection with the slide d, are two carriers or joined carrier shaped parts
forming a semi-circular or bridge-shaped piece f, for carrying or holding the screw 9,
(see Figure 3,) which screw by its action forces the borer or drill h, into the coal,
rock, or other mineral being operated on, the screw carrier bridge-shaped piece f,
is so made and fitted as to slide up and down the boring pillar b, and the frame a,
in order to work the borer or drill as required.
In Figure 5, i, is the split nut which is fitted in the carrier or bridge-shaped
piece f, to hold the screw g, in position for working.
The top of the frame a, of the apparatus is made pointed or sharp at a², to fix into
the roof, top, or other convenient part of the gallery, passage, or shaft of the coal
mine or other place where the boring is being done.
This pillar apparatus, when fixed in the required place, is operated just like other
coal or mineral boring machines that are worked by hand; and its working is
controlled by means of the ordinary ratchet appliance which (though not shown
in the drawing) is fitted onto one end of the screw g, the borer or drill h, being
coupled to the other end of it by couplings j, shown at Figures 3, and 6, which are
placed on the ends of the screw and the borer or drill, and are then securely locked
thereon by means of one or more thumbscrews k. The raising and lowering of the
slide d, is operated and controlled by the locking appliance e, and ratchet handle e¹,
before referred to; and so is the sliding pillar b.
The end of the screw or worm c, is so formed at 7, that a loose pin or handle bar m,
is passed through it to turn or work the screw c, in raising or lowering the pillar b.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
The general construction and novel adaptation and combination of working parts
forming as a whole an improved efficient reliable and durable "Miners' Boring
Pillar machine or apparatus, and its use for boring coal rock or other mineral;
substantially as herein has been described, and as illustrated on the accompanying
sheet of drawings.
