I EDWIN DIXON of Merridale Grove Wolverhampton in the County of Stafford
Gentleman do hereby declare the nature of the said Invention for "ÅN IMPROVE-
MENT IN THE PRODUCTION OF IRON AND STEEL STRIPS AND PLATES FOR THE
MANUFACTURE OF LAP-WELDED TUBES AND OTHER HOLLOW CYLINDERS" to be as
follows:-
In the manufacture of lap welded tubes as ordinarily practised the strips or
plates are rolled with flat edges which edges require to be bevilled for the production⚫
of the lap-joints of the tubes before the said strips or plates are bent into skelps.
The said bevilling of the edges of the strips or plates is ordinarily effected while
the said strips or plates are in a cold state by cutters.
My invention consists in bevilling the edges of the strips or plates by the rolling
process by which the said strips or plates are produced instead of first rolling the
strips or plates with flat edges and by a subsequent process bevilling the said edges.
For the production of the said bevil edged strips or plates I give preferably to the
last or finishing groove of the rolls a shape the counterpart in cross section of the
strip or plate to be made that is the groove instead of having fiat ends as usual is
furnished with ends inclining in the same direction so as to produce a strip or plate
having bevilled edges the inclination of the edges of the rolled strip or plate being
in the same direction. I do not however limit myself to the bevilling of the edges
of the strip or plate by the operation of the last groove in the rolls as the whole or
some of the grooves through which the strip or plate is passed may be inclined for
the production of the bevil edged strips or plates.
By my invention the bevil edged strips or plates are produced by one operation
and are ready without further treatment to be heated and bent into skelps for the
manufacture of lap-welded tubes. A process is thereby saved and the manufacture
of the tubes is economized.
Although my invention is especially applicable to the manufacture of lap welded
tubes yet my said invention is also applicable to the manufacture of other hollow
cylinders such for example as the cylinders of pumps and the like.

I EDWIN DIXON of Merridale Grove, Wolverhampton, in the County of Stafford,
Gentleman, do hereby declare the nature of my Invention for "AN IMPROVEMENT
39
IN THE PRODUCTION OF IRON AND STEEL STRIPS AND PLATES FOR THE MANU-
FACTURE OF LAP-WELDED TUBES AND OTHER HOLLOW CYLINDERS and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :—
In the manufacture of lap welded tubes as ordinarily practised the strips or
plates are rolled with flat edges which edges require to be bevilled for the production
of the lap joints of the tubes before the said strips or plates are bent into skelps.
The said bevilling of the edges of the strips or plates is ordinarily effected while
the said strips or plates are in a cold state by cutters.
My invention consists in bevilling the edges of the strips or plates by the rolling
process by which the said strips or plates are produced instead of first rolling the
strips or plates with flat edges and by a subsequent process bevilling the said edges.
For the production of the said bevil edged strips or plates I give preferably to the
last or finishing groove of the rolls a shape the counterpart in cross section of
the strip or plate to be made: that is, the groove instead of having flat ends as usual
is furnished with inclined ends so as to produce a strip or plate having bevilled
edges the inclination of the edges of the rolled strip or plate being either in the
same or in opposite directions. I do not however limit myself to the bevilling of
the edges of the strip or plate by the operation of the last groove in the rolls as the
whole or some of the grooves through which the strip or plate is passed may be
inclined for the production of the bevil edged strips or plates.
By my invention the bevil edged strips or plates are produced by one operation
and are ready without further treatment to be heated and bent into skelps for the
manufacture of lap-welded tubes. A process is thereby saved and the manufacture
of the tubes is economized.
Figure 1 of the accompanying Drawing represents in edge view and plan,
a portion of an iron or steel strip or plate the edges of which are bevilled according
to my invention. The bevilled edges of the strip or plate are marked a, a the said
bevilled edges being situated on opposite faces of the strip or plate and inclining
in the same direction.
The bevil edged strip or plate Figure 1 is produced by rolling as herein before
described.
Figure 2 represents in end elevation and side elevation, a skelp bent or fashioned
in the ordinary way from the bevil edged strip or plate Figure 1 the said skelp
being used for the manufacture of a lap welded tube.
Figure 3 represents in edge view and plan a portion of an iron or steel strip or
plate the edges of which are bevilled according to my invention. In this strip

page_text: or plate the bevilled edges a, a are situated on the same face of the strip or plate
and are inclined in opposite directions as represented. Figure 4 represents in end
elevation and side elevation a skelp bent or fashioned in the ordinary way from the
bevil edged strip or plate Figure 3, the said skelp being used in the manufacture
of a lap welded tube.
Although my invention is especially applicable to the manufacture of lap welded
tubes yet my said invention is also applicable to the manufacture of other hollow
cylinders, such for example as the cylinders of pumps and the like.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as my
invention of "An improvement in the production of iron and steel strips and plates
for the manufacture of lap welded tubes and other hollow cylinders
"
Bevelling the edges of the said strips or plates by the rolling process by which
the said strips or plates are produced as herein before described and illustrated in
the accompanying Drawing instead of first rolling the strips or plates with flat or
square edges and by a subsequent process bevilling the said edges as usual.
