page_text: be Constructed for Use Independently of the Flask.
We, WALTER THORNHILL, and HUBERT THORNHILL, trading together under the
firm of Walter Thornhill and Company, of 144 New Bond Street, in the County
of Middlesex, Silversmiths, and GODFREY ZIMMERMAN, of the same place, employé
in the said firm, 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, reference being had to the accompanying
drawings, and to the letters and figures marked thereon, that is to say :-
This Invention relates more particularly to the combination, forming a single
article, of a drinking-flask and a sandwich-box, this latter being formed integrally
with the flask, and so constructed and arranged as to be readily built up, when
desired, or to be folded and lie upon one of the faces or sides of the said flask, when
not in use, so as to occupy but little space and thus form a compact whole.
The sandwich-box may also be constructed for use independently of the drinking-
flask, the same arrangement of its parts being retained.
We proceed with reference to the accompanying drawings to fully describe a
combined drinking-flask and sandwich-box constructed according to the first part
of our Invention.
Figs. 1, 2, 3 and 4 are views representing the combined article in the condition
it would assume when the parts forming the sandwich-box are folded and out of
use, the lid C of said box then forming one of the faces or sides of the flask, Fig. 1
is an elevation of the combined article, Fig. 2, a side view, Fig. 3, a top view, and
Fig. 4, a cross section taken on line x, x of fig. 1.
Figs. 5, 6, 7 and 8, are views representing the article built up to form the com-
bined drinking-flask and sandwich-box, Fig. 5 being an elevation of one of the
sides (the back), Fig. 6 an elevation of the front side, Fig. 7 a top view and Fig. 8
a cross section taken on the line y, y, of Fig. 5. Fig. 9 is a perspective view
shewing the combined flask and sandwich-box in its partially built up condition,
so as to permit of the various parts, and the connections being clearly seen.
A, is the flask which is, by preference, made of metal, and is provided with the
usual nozzle and cap a. To the upper lateral edges of this flask the pieces B, B',
forming respectively the frout and back of the box, are hinged at 6, 6¹. The

page_text: front piece B, is furnished at its extremities with double hinges c, c', to which are
connected other pieces or flaps B³, B³, forming the ends of the box. These pieces
or flaps, together with the front piece B, are capable of being folded, as shewn in
fig. 4, when they are not required to form the box. The back piece B¹, is con-
structed in two portions, which are likewise hinged or jointed together at 6'. At
its upper edge, the piece B', is hinged at 6, to the lid C, so that this back piece B¹,
can also be folded down and lie snugly as shewn in fig. 4. D, is the bottom of the
sandwich-box which is formed by one of the sides of the flask.
The pieces or flaps B2, B3, constituting the ends of the box, are formed with
catches d, d, which engage or take into notches d*, d³, formed in the lower half of
the piece B¹, and these catches, together with the stops e, e¹, maintain the ends and
front portions of the box in their rigid upright position. The two portions forming
the back piece B¹, are flanged at each of their ends, as shewn at f, f, f¹, f¹, fig. 9;
the flanges ff, on the lower half, take over or on to the ends or flaps B³, B³,
which are formed with a depression to permit of said flanges lying flush with the
flaps or end pieces when built up, and, at the same time, to maintain the required
rigidity of the ends and front piece. These parts being thus combined and
arranged, the upper half the back piece B', is then straightened upon its central
binge 6, and its flanges f, f, also engage in the same manner as f¹ƒ³, with the
flaps B2, B3. The lid is now brought over and the box is closed.
The hinges c, c¹ are what are commonly known as double-hinges, the object in
employing the same being to allow of the flaps or end pieces B³, B³, being folded
over the front piece B, when the box is to be folded, and to cause the said flaps or
end pieces to take up their position at right angles to the back and front pieces B, B¹,
when building up the box.
Figs. 10 and 11 are sectional views of the sandwich-box constructed for use
independently of the drinking flask, the same letters of reference indicating
similar parts to those in the combined arrangement of drinking-flask and sandwich-
box. In fig. 10, the box is shewn folded, and in fig. 11, built up. The front and
back portions B, B1, (fig. 11) are hinged to the plate D forming the bottom of the
box, and the portions B and B (fig. 10) are binged to the piece B, forming the
front portion of the box, in precisely similar manner as in the combined arrange-
ment of drinking-flask and sandwich-box herein before described.
Having now described our Invention, and in what manner the same is to be
performed, we declare that we claim :—
1. The combination, forming a single article, of a drinking-flask and sandwich-
box, the said box being formed integrally with the flask and having its parts,
constructed, arranged and combined to be operated substantially as herein specified
and illustrated in the drawings, and for the purpose set forth.
2. The special arrangement of combined drinking-flask and sandwich-box, as
described and shewn with reference to figs. 1 to 9 of the drawings, (both inclusive).
3. The construction of folding sandwich-box, as herein described and shewn with
reference to figs. 10 and 11 of the drawings.
