CERTAIN IMPROVEMENTS IN THE MANU- FACTURE OF TRUNKS BOXES, AND OTHER SIMILAR DEPOSITORIES" PROVISIONAL SPECIFICATION
Year: 1857

page_text: LETTERS PATENT to Edward Kirk, Ironmonger, James Leadbetter,
Brazier, and Charles Wilson, Ironmonger, all of Leeds, in the County
of York, for the Invention of "CERTAIN IMPROVEMENTS IN THE MANU-
FACTURE OF TRUNKS BOXES, AND OTHER SIMILAR DEPOSITORIES"
PROVISIONAL SPECIFICATION left by the said Edward Kirk, James
Leadbetter, and Charles Wilson at the Office of the Commissioners
of Patents, with their Petition, on the 20th June 1857.
We, EDWARD KIRK, Ironmonger, JAMES LEADBETTER, Brazier, and
CHARLES WILSON, Ironmonger, all of Leeds, in the County of York,
do hereby declare the nature of our said Invention for "CERTAIN
IMPROVEMENTS IN THE MANUFACTURE OF TRUNKS, BOXES, AND OTHER SIMILAR
DEPOSITORIES," to be as follows:-
The first part of our Invention is designed for the purpose of strengthening
the lid or cover of metallic trunks, boxes, or depositories, which is effected by
bending or otherwise forming such lid in a succession of angles, the inter-
mediate surfaces between which being either plain or curved; as preferred.
Secondly, our Invention relates to the novel methods of fastening or
securing the sides of the box together at the juncture or corners of the box,
which improvement consists in so cutting the metal of each of the sides
that a projecting piece may remain on each to overlap and be revitted to
the side abutting against it.
Aud, thirdly, our Invention relates to a novel manner of forming or
[Price 8d1

page_text: obtaining the bead or rib, usually employed at the upper edge of the box,
and upon which the lid closes. This may be effected either by bending
over the metal of the side and turning or swelling the same out into a
hollow rib or bead, or by formning a light bead upon a separate piece and
attaching the same to the side by a double bend and hammering both
together; or, in a more simple manner, by mearly bending the separate
piece over the upper edge of the side.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Kirk, James Leadbetter, and Charles Wilson
in the Great Seal tent Office on the 19th December 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
KIRK, Ironmonger, JAMES LEADBETTER, Brazier. and CHARLES WILSON,
Ironmonger, all of Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of June, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the
said Edward Kirk, James Leadbetter, and Charles Wilson, Her especial
license that we, the said Edward Kirk, James Leadbetter, and Charles
Wilson, our executors, administrators, and assigns, or such others as we,
the said Edward Kirk, James Leadbetter, and Charles Wilson, our executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "CERTAIN IMPROVEMENTS IN THE MANU.
FACTURE OF TRUNKS, BOXES, AND OTHER SIMILAR DEPOSITORIES," upon the condition,
amongst others, that we, the said Edward Kirk, James Leadbetter, and
Charles Wilson, by an instrument in writing under our hands and seals, or
under the hand and seal of one of us, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Wilson, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,

page_text: to be particularly described and ascertained in and bythe following statement
and accompanying Drawings (that is to say):-
The first part of our Invention is designed for the purpose e of strengthening
the lid or cover of metallic trunks, boxes, or repositories, which is effected by
bending or otherwise forming such lid in a succession of angles, the inter-
mediate surfaces between which being either plain or curved, as preferred.
Secondly, our Invention relates to the novel method of fastening or securing
the sides of the box together at the juncture or corners of the box, which
improvements consist in so cutting the metal of each of the sides that a
projecting piece may remain on each to overlap, and be rivetted or soldered
to the side abutting against it.
And, lastly, our Invention relates to a novel manner of forming or
obtaining the bead or rib usually employed at the upper edge of the box,
and upon which the lid closes. This may be effected either by bending
over the metal of the side and turning or swelling the same out into
a hollow rib or bead, or by forming a like bead upon a separate piece of
metal and attaching the same to the side by a double bend and hammering
both together; or, in a more simple manner, by merely bending the separate
or detached piece over the upper edge of the side of the box.
In order that the Invention may be better understood and explained in
detail, we have hereunto annexed a Sheet of Drawing illustrative of the
said improvements, in which Fig. 1 is a perspective view of a trunk or box
to which is applied a curved lid or cover, such form of lid being one of the
most approved for strengthening the lid, and enabling it to withstand outward
pressure without being subject to bend inwards, as is the case with ordinary
arched lids or covers; Fig. 2 represents a series of sectional lineal Diagrams,
shewing a variety of forms which may also be employed for the purpose of
strenthening the box cover.
The second part of the Invention, for securing the sides of the box together,
is shewn at Fig. 3, the plain edges being overlapped or turned into each other
aud then hammered together, as shewn at A; the junction at the corners
where a ledge is formed being effected by so cutting the metal that projecting
pieces may be left on each side to overlap and be rivetted upon the side
abutting upon it, as seen at Fig. 3; B, the blue and red lines, serving to
distinguish the projecting pieces belonging to each side.
The last part of our Invention will be seen at Fig. 4, such being the
formation of the hollow rib or bead upon which the lid closes. At C is seen
the side of the box bent over (in blue line) and the detached piece of metal
swelled into a hollow rib (shewn in red) and overlapping or bent into each

page_text: other; a more simple method being to bend the side of the box into such
hollow rib, as seen in end and side view at D, or forming it as at F, and
securing the sides by overlapping, as at E.
Having now described the nature of our said Invention, together with the
method of performing the same, we would remark, in conclusion, that we
claim,―
First, manufacturing or forming the lid or cover of trunks, boxes, or other
depositories in a succession or series of angles, with either plain or curved
surfaces between them, and whether such lines or angles extend in the
direction of the length of such boxes or in that of the width thereof.
And also the novel method of producing or forming the rib or bead upon
which the box closes, the whole of which improvements are herein-before
described, set forth, and fully exhibited in the Drawings annexed.
In witness whereof, I, the said Charles Wilson, have hereunto set my
hand and seal, this Seventeenth day of December, in the year of our
Lord One thousand eight hundred and fifty-seven.
CHARLES WILSON. (.S.)
