PROVISIONAL SPECIFICATION.
A New or Improved Tub or Vessel for Use in Collieries, Mines, and
other Places.
I, WILLIAM HESLOP, of Westmoreland Avenue, Bridlington Quay, in the
County of York, Engineer, do hereby declare the nature of this invention to be as
follows
The object of my invention is to construct coal tubs, buckets, or other similar
vessels (hereafter called tubs) in such a manner that they are lighter, stronger,
and less liable to leak, than tubs hitherto employed.
According to my invention I employ a single sheet of metal which is cut to a
suitable pattern according to the required shape of the tub to be produced. I then
bend up the sides of the plate, allowing the metal to crinkle or corrugate, leaving
the sides vertical or nearly so, with a wavy edge and corrugations running down the
sides of the tub, diminishing in depth as they descend towards the base. The base
of the tube may be square, round, or of other suitable shape, and, the corrugations
on the sides may be of any number or depth required, it being obvious that the
smaller the corrugations the greater number will be required, whilst if the
corrugations are large, comparatively few will be needed.
This corrugated formation renders the tubs extremely strong, though should they
require to be still further strengthened, this can be effected by means of a band
fitted to the rim or other suitable part. A false bottom may conveniently be
employed in connection with these tubs, and when one false bottom is worn out, it
can be readily replaced by another.
It will be understood that the above described tubs require no rivets in their
main construction, and consequently the liability of their becoming leaky is very
small, thus rendering them particularly applicable in the manufacture of life saving
seats or other articles requiring to be perfectly watertight.

COMPLETE SPECIFICATION.
A New or Improved Tub or Vessel for Use in Collieries, Mines, and
other Places.
I, WILLIAM HESLOP, of Westmoreland Avenue, Bridlington Quay, 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 :-
The object of my invention is to construct coal tubs, buckets, cisterns, or other
similar vessels (hereafter called tubs) in such a manner that they are lighter,
stronger, and less liable to leak than tubs hitherto employed.
In order that my invention may be clearly understood I will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer
to like parts in all the figures.
Fig. 1 is a section. Fig. 2 is a plan. Fig. 3 is an end view, and Fig. 4 is a
perspective view of a tub constructed according to my invention.

page_text: Figs. 5, 6, 7 and
are respectively a section, a plan, au end view, and a
perspective view, of a slightly modified form of tub.
According to my invention I. employ a single sheet of metal, which is cut to a
suitable pattern, according to the. required shape of the tub to be produced. This
sheet of metal is then pressed between suitable dies, whereby such plate or sheet is
formed into a tub, having sides A, ends B and a base C, the said pressing operation
allowing the metal to crinkle, the superfluous metal being taken up in the
corrugations D, as shown at Sheet 1 of the drawings. The sides A and ends B of
the tub are thus left vertical or nearly so, having a wavy upper edge, and
corrugations D running down such sides and ends, diminishing in depth as they
:descend towards the base C.
In order to strengthen and stiffen the base C of the tub, I cause corrugations D
to be formed in same, which may be effected simultaneously with the formation of
the said tub, or at a separate operation.
Referring to Sheet 2 of the drawings, a tub will be seen having its sides A
corrugated in a similar manner to that above described. The superfluous metal in
the ends B is taken up by the folds E, which are bent round as seen in the drawings,
such folds E being firmly locked in position by means of the turned-over laps F.
The base C of the tub may also be corrugated at D as shown.
A false bottom may conveniently be employed in connection with these tubs, and
when one false bottom is worn out, it can be readily replaced by a new one, thus
prolonging the life of the said tub indefinitely.
The corrugated formation renders the tubs extremely strong, and in cases where
the ends require to be of extra strength, the tub having folded ends as shown in
Sheet 2 of the drawings may most suitably be employed. Should the tubs require
to be still further strengthened, a band may be fitted to the rim or other suitable
¡part.
The base of the tub may be square, round, or other suitable shape, and the
corrugations thereon may be of any number or depth according to requirements.
It will be understood that the above described tubs require no rivets in their
construction, and consequently the liability of their becoming leaky is very
small, thus rendering them particularly applicable as coal tubs, and water cisterns,
or in the manufacture of ordinary life saving seats or other articles requiring to be
perfectly water tight.
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 :
1. The construction of a tub or other vessel pressed or stamped from a single sheet
of metal, and having its sides, ends, and base corrugated, substantially as and for
the purposes set forth.
2. The construction of a tub or other vessel, pressed or stamped from a single
sheet of metal, and having its sides and base corrugated, and the superfluous inetal
at its end folded and locked, substantially as and for the purposes set forth.
3. The general arrangement and construction of tubs or other vessels forming
my invention, substantially as and for the purposes set forth.
