Improvements in and Apparatus for Coal Mining.
•
I, The Right Honourable SAMUEL CUNLIFFE, BARON MASHAM, of Swinton,
Masham, in the County of York, do hereby declare the nature of this invention
to be as follows:-
According to my present invention, after the dirt partings between the seams
have been removed by a scooping machine, or by any other means, I mount a
drill or drills on a frame so as to pierce the coal at the back of the scooping, or
nearly so suppose the dirt partings to be scooped out between the seams to the
extent of a yard, the drills by piercing the coal at the back are so arranged as to
cut it off to that extent or nearly so. If there are several seams, which is usually
the case, the drills are mounted in a frame one above the other, so as to operate
simultaneously upon all the seams.
Sometimes it is necessary to make two sets of holes before the coal will by
gravity break down, in that case, the drills are so arranged that by suitable
mechanism the second set of holes can be made to intersect the others.
The drilling machine is made to travel on the top of the lowest seam in order
to back cut all the upper ones.
Where it can be done conveniently, that is where the seam is a sufficient height
from the floor I place or fix a supporting plate under the coal so that when it is
detached it may slide down an incline into a corve placed ready to receive it
thereby effecting a considerable economy.
The receiving plate may be made in two ways, first to receive the portions of
detached coal when standing in a horizontal position, and then by suitable
mechanism it may be made to "tip" or "type" it into the corves down an incline
or the plate may instead of being horizontal be made to incline so that the
moment the coal comes on to it, it will at once slide down into the corve.

I, The Right Honourable SAMUEL CUNLIFFE, BARON MASHAM, of Swinton,
Masham, in the County of York, 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 are illustrated in the drawing annexed

page_text: According to my present invention after the dirt partings between the seams
have been removed by a scooping machine or by any other means as illustrated in
the plan view Figure 1 and in the vertical section Figure 2 taken on the line A B
Figure 1 I cause a number of circular holes to be pierced into the coal at the
back of the scooping or nearly so by a drill or drills mounted in a suitable frame
vertically one above the other. Suppose the dirt partings to be scooped out
between the seams to the extent of a yard, the drills by piercing the coal at the
back are so arranged as to cut it off to that extent or nearly so.
If there are
several seams, which is usually the case, the drills are mounted in a frame one
above the other, so as to operate simultaneously upon all the seams.
Sometimes it is necessary to make two sets of holes before the coal will by
gravity break down, in that case the second set of holes can be made to intersect
the others and the drill carrying frame be mounted in vertical guides on the
drilling machine carriage so that it may be raised or lowered as desired.
1
The drilling machine carriage is made to travel on the top of the lowest seam 1
in order to back cut all the upper ones.
If desired vertical cuts or rows of holes may be made into the face of the coal
as indicated by the dotted lines c in Figure 1 in addition to scooping out the dirt
partings a and boring the series of holes b at the back so as to facilitate the
breaking down of the coal in blocks of uniform size.
Where it can be done conveniently, that is where the seam is a sufficient height
from the floor I place or fix a supporting plate under the coal so that when it is
detached it may slide down an incline into a corve placed ready to receive it
thereby effecting a considerable economy.
2
The receiving plate may be made in two ways, first to receive the portions of:
detached coal when standing in a horizontal position, and then by suitable
mechanism it may be made to "tip" or "type" it into the corves down an incline
or the plate may instead of being horizontal be made to incline so that the
moment the coal comes on to it, it will at once slide down into the corve.
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:
In coal mining the boring a number of holes one above the other into the coal
at the back of any portion of the coal which has been undercut so as to facilitate
the breaking down of this undercut portion.
