Improvements in the Construction of Sheet Metal Travelling
Trunks, Cash, Deed, and Bonnet Boxes, and like Articles.
I, JOSEPH GRIMES LLOYD of Holmleigh Lee Road Wolverhampton in the
County of Stafford, Trunk Manufacturer 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 body and lid of sheet metal trunks when constructed in the way usual to
the trade, are made of a special soft quality of sheet iron or steel, which is very
expensive. Cheap qualities of iron or steel cannot be used as being hard and
brittle, it will not stand the severe strain of wrapping over at joints of various
parts.
I have discovered a method of construction, by which the cheaper quality of
iron or steel may safely be used and less labour is entailed in construction. By
this method I shall be able to produce a trunk that will be stronger when made,
easier to make and far less costly than if constructed in the way now usually
adopted by the trade.
In order that the nature of my invention may be more clearly understood I will
describe it in reference to the accompanying drawings and the letters of reference
marked thereon. The same letters occuring in different figures indicate corre-
sponding parts.
Figs. 1 & 2 represent front and end views of sheet metal trunk.
Fig. 3 is an enlarged view of part of Fig. 1 as marked A.
Fig. 4 is an enlarged view of part of Fig. 2 as marked B.
Fig. 5 is a section through Fig. 3.
and
As will be seen by Figs. 3, 4 & 5 the narrow piece of sheet metal a is placed
between the sheet that forms the body b, and the turned up edge of end c. The
outside edge of the piece a is rolled outwards, as shown on Fig. 5, and forms a
ridge on front edge of trunk, that assists in strengthening and protecting it. The
sheet that forms the body b is pushed into the position shown on Figs. 3 &
the whole are secured together with the small rivets d at required distances round
the edges of the trunk. The top e and end of the lid are made and secured
together in the same manner as specified for the body of the trunk. By the use of
the said piece, a, the joints between the said parts are made without any wrapping
over, so that the small piece a will be the only metal in construction of the trunk,
that will require to be of the special soft quality before mentioned.
In cases where trunks are to be made of extra strong guage of metal, the
piece a can be dispensed with and the edges of the metal that forms the trunk body
itself, can be turned outwards as shown on Fig. 6.
I have drawn all the figs. to scale, but I do not bind myself to the particular
size and shape of the trunk shown on the drawings as this invention will apply in
the same manner to cash, deed and bonnet boxes and such like articles which are
made of sheet metal.
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 method of making and securing together the various parts of sheet metal
trunks and articles of a like nature substantially the same as shown and described
in the Specification and the sheet of drawings accompanying the same.
