IMPROVEMENTS IN OR RELATING TO METALLIC TRUNKS, BOXES, AND SIMILAR ARTICLES
Year: 1884

page_text: I, ROBERT FOSTER, of 51 Moseley Street, Birmingham, in the County- of
Warwick, Trunk Manufacturer, do hereby declare the nature of my Invention
for "IMPROVEMENTS IN OR RELATING TO METALLIC TRUNKS, BOXES, AND SIMILAR
ARTICLES," to be as follows:-
This Invention has reference to certain improvements in or relating to the
manufacture of metallic trunks, boxes, and similar articles, and consists of improved
means of jointing or connecting together the bottom, sides, or other parts of such
articles when made of sheet metal, an especial object of the Invention being to
cheapen the manufacture of such articles.
As generally made, the bottoms, sides, or other parts or pieces of which the
trunk, box, or like article is composed, have been jointed or put together by over-
lapping the adjacent edges of the adjoining parts for the entire length of the parts
being joined.
According to the present improvements, I unite the edges of the parts by means
of a joint piece formed independently of the parts to be connected. The edges of
the parts to be connected I turn down, and the joint piece I make of an angular
formation, also turning down the edge of each of its parts but reversely to the way
the other parts are turned, so that upon piercing the parts to be connected in the
proper relative position I cause them to be connected by sliding the reversely formed
joint piece along the turned down edges so as to engage therewith and secure the
parts The joint is perfected by hammering or otherwise flattening the connected
parts together, this leaves slightly projecting parts adjacent to the angles and
which are of considerable service in preventing the body of the bottom of the trunk
or article from being damaged in resting on an uneven surface.

I ROBERT FOSTER of No. 51 Moseley Street Birmingham in the county of
Warwick Trunk Manufacturer do hereby declare the nature of my invention
for "IMPROVEMENTS IN OR RELATING TO METALLIC TRUNKS, BOXES, AND SIMILAR
ARTICLES and in what manner the same is to be performed to particularly
described and ascertained in and by the following statement, that is to say:-
"
This invention has reference to certain Improvements in or relating to the
manufacturer of metallic trunks, boxes and similar articles and consist of improved
means of jointing or connecting together the bottom-sides or other parts of such
articles when made of sheet metal, an especial object of the invention being to
cheapen the manufacture of such articles.
As generally made, the bottoms, sides, or other parts or pieces of which the
trunk, box, or like article is composed, have been jointed or put together by over-
lapping the adjacent edges of the adjoining parts for the entire length of the parts
being jointed.
According to the present improvements I unite the edges of the parts by means
of a joint peice formed independently of the parts to be connected. The edges of
the parts to be connected I turn down, and the joint pieces I make of an angular
formation also turning down the edges of each of its parts but reversely to the way
the other parts are turned so that upon placing the parts to be connected in the
proper relative position I cause them to be connected by sliding the reversely
formed joint piece along the turned down edges so as to engage them with and
secure the parts. The joint is perfected by hammering or otherwise flattening the
connected parts together this leaves slightly projecting parts adjacent to the angles
and which are of considerable service in preventing the body of the bottom of the
trunk or article from being damaged in resting on an uneven or other surface.
In order that my invention may be easily understood and carried into practice
without difficulty, I have appended hereunto a sheet of drawings showing the
application of the invention to a part of a trunk.
Figure 1 is a perspective view of a trunk made according to my invention from
which it will be noticed that the angles A, B C and D are made flat and broader
than is usual with such trunks. In order to show the details more fully I have
made an enlarged section on the dotted line E, F as shown by Figure 2 before-the
joint is hammered or otherwise flattened down.
Figure 3 is a section of the corner piece separate and
Figure, 4, shows the side and end bent up separate ready to receive the said
corner pieces It will be noticed from Figure 1 that there are rivetted corner
pieces H, J, K, L at each end of the box. These are for the purpose of filling up
the gaps left, at the round ends The sides or other straight or flat parts are
notched as shown by Figure 5. with the pieces notched out as shown by The pro-
jecting pieces Q, R, T and S are then bent round as shown by Figures 6 and 7.
Figure 7 illustrates the mode of jointing the two plates when they meet under the
bottom of the box and Figures 8 show the parts separated. It will thus be seen

page_text: that plates of metal are taken and notched out at the' parts where circular corners
come and these corners are afterwards made up with corner pieces as shown by
Figure 1 but the plain straight parts are placed together as shown at Figure 4 and
corner clip Figure 3 is slided on or the piece W Figures 8 if the joint is a plain
one. In the case of flat joins as shown Figure 7 the metal is tooled down at v
and to keep the plates locked together.
Boxes thus made will be much stiffer at the corners and they may be put
together with less skilled labour-It will also be seen that the design is applicable
to many kinds of boxes and joints for various purposes.
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
The improvements in or relating to metallic trunks boxes and similar articles of
the new mode of joining the corners together by turning the edges back and sliding
over the said edges supplemental pieces such as shown by Figure 3 and W
Figure 8 substantially as berein set forth.
