AN IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF METALLIC NEEDLE CASES
Year: 1884

page_text: I WILLIAM AVERY of the Firm of William Avery and Son of Headless Cross
near Redditch in the County of Worcester Needle Manufacturers do hereby declare
the nature of the said Invention for "AN IMPROVEMENT OR IMPROVEMENTS IN THE
MANUFACTURE OF METALLIC NEEDLE CASES" to be as follows:-
My invention consists in manufacturing flat metallic needle cases each from a
single blank or piece of sheet metal in the manner hereinafter described.
I take a blank or strip of thin sheet metal somewhat more than twice as long as
the case to be made. One half of this blank or strip is wider than the other half
the two parts or halves of unequal width being joined by a neck or contracted part
which contracted part in the finished needle case constitutes the bottom of the
case The shaped blank or strip having been ornamented while in the flat the
longer edges of the wider half are raised at right angles and form flanges. Tho
two halves of the blank are next doubled at the middle or contracted part and are
brought parallel to one another the narrow half of the blank engaging with or
passing between the raised edges or flanges ou the wider half. The raised edges
or flanges on one half of the partly made case are next closed upon the edges of
the other half of the case so as to bind the two halves securely together. A flat
metallic case is thus formed from one piece of sheet metal the bottom of the case
being made from the contracted part or neck at the middle of the blank and the
edges from the raised parts or flanges made at the edges of one half of the blank
as before described.

page_text: I WILLIAM AVERY of the Firm of William Avery and Son of Headless Cross
near Redditch in the County of Worcester, Needle Manufacturers do hereby declare
the nature of my Invention for "AN IMPROVEMENT OR IMPROVEMENTS IN THE
MANUFACTURE OF METALLIC NEEDLE CASES" and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement-
My invention consists in manufacturing fat metallic needle cases, each from a
single blank or piece of sheet metal in the manner hereinafter described.
I take a blank or strip of thin sheet metal somewhat more than twice as long as
the case to be made. One half of this blank or strip is wider than the other half
the two parts or halves of unequal width being joined by a neck or contracted
part, which contracted part in the finished needle case constitutes the bottrom of
the case.
The shaped blank or strip having been ornamented while in the flat, the
longer edges of the wider half are raised at right angles and form flanges.
The two halves of the blank are next doubled at the middle or contracted part
and are brought parallel to one another the narrow half of the blank engaging
with or passing between the raised edges or flanges on the wider half. The raised
edges or flanges on one half of the partly made case are next closed upon the edges
of the other half of the case so as to bind the two halves securely together A flat
metallic caso is thus formed from one piece of sheet metal the bottom of the case
being mado from the contracted part or neck at the middle of the blank and the
edges from the raised parts or flanges made at the edges of the blank as before
described.
Figure 1 of the accompanying Drawing represents the blank of thin sheet metal
from which the metallic needle case is to be made, the said Figure 1 and the other
Figures herein after described being drawn double the full size. The halves of the
blank are marked a and b the half a being wider than the half b, the said halves
being joined by the neck or contracted part c.
Figure 2 represents the blank Figure 1 after its longitudinal edges have been
raised nearly at right angles to the body of the blank so as to form flanges. The
flanges on the longer edges of the half a are marked a², a² and those on the longer
edges of the half bare marked b², 6. The prepared blank Figure 2 is next folded
at the middle or contracted part c so as to bring the two parts ab of the blank
parallel or nearly parallel to one another, the flanges of the narrow half b of
the doubled blank engaging with or passing between the flanges a², a² of the
wider half a.
Figure 3 represents the blank after it has been so doubled but in order the
better to exhibit the flanges of the doubled blank, the two parts ab are represented
slightly separated from one another.
The raised edges or flanges a², a of the wider half a of the partly made case aro
next closed upon the raised edges or flanges b, 6 of the other half b of the case so
as to bind the two halves a, b together and thereby complete the case as illustrated
in the fiuished needle case shown in front elevation and edge view in Figure 4 and
plan in Figure 5.
A flat needle case is thus made from a single blank or piece of sheet metal the
edges of the case being formed from the raised parts or flanges a² a²; b², b² of the
blank and the bottom of the case from the contracted or neck part c of the blank.
Instead of joining the two halves of the blank from which the case is made end
to end they may be joined side to side with the same result: Figure 6 represents

page_text: a blank of this kind, a being the wider part of the blank and b the narrow part.
The side and bottom edges of the blank having been raised so as to form the
flanges a², a and b, be as represented in Figure 7, the blank is doubled or folded
at the dotted line d so as to form the partly made needle case represented in end
elevation in Figure 8. The flanges b2, 2 on the narrow half of the doubled
blank Figure 8 can now pass into or between the flanges a³, a² on the wider half a
and by closing the side and bottom flanges a, a² of the wider half a upou the side
and bottom flanges b³, b² of the narrow half b the two halves ab are connected
together and the needle case completed as illustrated in Figure 9.
In this modification the bottom of the case is formed by the closed bottom
flanges and one edge of the case by the closed side flanges and the opposite edge
by the fold at d where the doubling of the two halves of the blank takes place as
seen in the drawing.
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
Manufacturing flat metallic needle cases, each from a single rectangular blank or
piece of sheet metal, one half of the blank being wider than the other half and its
edges being provided with flanges as described and illustrated; doubling the
flanged blank at its middle so as to bring the two halves parallel and finally closing
the flanged edges of the doubled blank upon one another substantially as herein
before described and illustrated in the accompanying Drawing.
