Improvements in Colliery and similar Corves or Tubs.
I GEORGE MILNES, of Victoria Saw Mill, Summer Lane, Barnsley, in the
County of York, Colliery Plant Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to colliery and similar corves or tubs the object being to
arrange and construct a substantial and light corve in such a manner that the
maximum of strength is maintained with the minimum of material, and the sides
and ends are so arranged that the coal-dust which escapes in corves as hitherto
arranged is kept within the corfe thus giving additional safety to the mine. To
attain these objects I first bend two pieces of angle iron so as to form two right
angles, the said angles forming the corners of the corve, I then take two separate.
strips of similar angle iron which I rivet bolt or otherwise secure to the lower
corners of said right angled angle iron so forming the lower parts of the sides of
corf thereby giving strength to the bottom part of corvf. I then build up the sides
and ends of corf with especially formed plates and rivet or otherwise secure thereto
the angled corners aforesaid.
These plates are made with flanges in such a manner that one plate will partially
overlap the other and the cross section of each lap preferably extends in a vertical
direction so that the coal-dust within the corve is prevented from escaping as will
be well understood. I prefer to employ two ordinary wood sole pieces the ends of
which form the buffers and I secure these to the under side of corf which latter is
preferably made of sheet iron or steel and the said soles are secured laterally by
angle pieces which have their middle parts cut and bent upwards so as to give
room for the draw bar which is fixed thereunder by four or more bolts. The said
draw bar is composed of a flat strip of iron extending along the under centre part
of corf and is fixed in position by bolts extending through the under angle stay and
bottom plates.
The upper part of corf receives a hoop of iron rivetted or bolted in position. In
some cases middle stays may be used.
My invention consists essentially in the combination of right angled angle pieces
forming the ends with angle pieces forming the lower parts of sides and the
partially over-lapping sides and ends plates and the especially formed cross bar for
latterally securing the soles with the draw bar.
It will be obvious that as the said corf is built up in parts as described it may
easily be repaired when required as each part may be removed and a fresh one
supplied without removing the remaining parts.
Dated this 1st day of June 1896.

page_text: 1 GEORGE MILNES, of Victoria Saw Mill, Summer Lane, Barnsley in the
County of York, Colliery Plant Manufacturer, 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:-
.This invention relates to colliery and similar corves or tubs, the objects being to
arrange and construct a substantial and light corf in such a manner that the
maximum of strength is maintained with the minimum of material, and the sides
and ends are so arranged that the coal dust which escapes in corves as bitherto
arranged is kept within the corf thus giving additional safety to the mine; and to
so build up my improved corf or tub in an improved arrangement of parts that it
may be easily and expeditiously repaired when required inasmuch as each part
may be removed and a fresh one supplied to its place without having to remove
the remaining parts; to attain which I arrange and construct my improved corf or
tub substantially in the manner described with reference to the accompanying
sheet of drawings in which
Fig. 1 is an isometric perspective view of my improved corf or tub complete and
Fig. 2 is a plan with the outside sides and ends removed.
Fig. 3 is a front view of an especially formed piece of angle iron 1 employ for
securing together the sole pieces, ends, bottom and drawbar."
Fig. 4 is an end elevation and Fig. 5 a plan of same.
Fig. 6 is a perspective view of the plates I employ for the building up of the sides
and ends of corf or tub.
Similar letters of reference denote corresponding parts in each view.
In constructing or building up my said improved corf or tub 1 first bend two
pieces of angle iron A, each piece forming two right angles, and the vertical parts
thereof form the four corners of the corf or tub as shown Figs. 1 and 2. I then
take two separate strips of similar angle iron B and rivet bolt or otherwise secure
them to the lower corners of said right angled bent angle iron A in such a manner
as to form the lower parts of side of corf or tub as shown in Figures 1 and 2 thereby
giving strength to the bottom part of corf or tub. I then build up the sides and
euds of corf or tub with especial formed plates C, and rivet or otherwise secure
these to the angled corners aforesaid as shown Fig. 1.
The said plates C are formed with flanges c¹ in such a manner that one plate will
partly overlap the other, and the cross section of each said lap or flange c¹ preferably
extends in a vertical direction as shown at Fig. 6 so that the coal dust within the
corf is prevented from escaping as will be well understood.
I employ two ordinary wood sole pieces D the ends of which form the buffers,
and secure these to the under side E of corf or tub, which latter is preferably
made of sheet iron or steel, and the said soles D are secured laterally together by
especially formed angle pieces H shown in detail at Figs. 3. 4. and 5. Each said
angle piece H has its middle part h¹ cut and bent upwards so as to give room for
the drawbar J which is fixed thereunder by bolts, rivets or other means.
The said angle peice H has its ends 2 bent down so as to form a bracket or box
and these ends are bolted or secured to the soles whilst the top part is secured to
the angle iron A and the bottom of corf E and drawbar J, thereby securing all the
main parts of corf together at the parts where strength is required. I would here
remark that it is obvious my said improved angle pieces boxes or stays H may be
fitted in like manner to any ordinary wood or other corf or tub. The drawbar J is
preferably composed of a flat piece or strip of iron extending along the under

page_text: centre part of corf or tub and is fixed in position by bolts or rivets extending
through the stays H and bottom plates E.
The upper parts of corf or tub may where desired receive a hoop of iron m
rivetted or bolted to the sides and ends as shown Fig. 1, and in some cases middle
stays or supports p may be employed. I would have it understood that my
invention consists essentially in the combination of right angled angle pieces A
forming the lower ends and corners with the angle iron B forming the lower parts
of sides, and partly overlapping end and side plates C; and also the especially
formed crossbar stays or boxes H for securing the soles, drawbar and bottom of
corf or tub together and I make no claim to any other part or combination of parts,
therefore.
Having now particular 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. In colliery or similar corves or tubs the combination of two bent pieces of
angle iron whose vertical parts form the corner stays and lower parts form the
lower parts of ends or sides with pieces of angle iron fixed thereto forming the
lower parts of sides or ends substantially as described and for the attainment of
the object specified.
2. In colliery or similar corves or tubs the use of side and end plates constructed
with flanged overlapping parts substantially as described and for the object
specified.
3. In colliery or similar corves or tubs the use of especially formed angle pieces
cross bars stays or boxes each being formed from a piece of angle iron and having
a bent up part for the attachment of drawbar and bent down ends for the
attachment of the soles or buffers and flanged upper parts for attaching to the
lower parts of ends and bottom of corf or tub substantially as described and.
illustrated.
