COMPLETE SPECIFICATION.
Improvements in Dies for Use in the Manufacture of Cases and
portions of Cases and the like for Holding and Displaying
Jewellery and other Articles.
I, GEORGE WHEELER, of 39, King Square, Clerkenwell, E.C., 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:
My invention relates to improvements in dies for use in the manufacture of cases
and portions of cases and the like for holding and displaying jewellery and other
articles. The objects are to provide means for forming the more or less convex
portions of cases of the kind referred to which are made of pasteboard or other
suitable material, and which are thereafter to be covered, padded, or otherwise
treated, a further object being to provide means whereby the parts are at one
operation pressed into the required shape and furnished with clean cut sharp edges so
sloped away that they will lie truly all round when placed on a level surface, thus
obviating the necessity for paring, sandpapering, or any similar treatment as is
required at present. The invention while particularly adapted for use in the making
of jewel cases and their parts, and of blocks for holding brooches, can nevertheless be
adapted for any analagous purposes. In carrying my invention into effect, I proceed
in or in about the following manner, making reference to the accompanying sheet of
drawings in which. Figs. 1 and 2, and 7 and 8, are plans. Figs. 3 and 4, and
9 and 10, are longitudinal sections, and Figs. 5 and 6, and 11 and 12, are cross
sections. Fig. 13, is a longitudinal section of a piece of material after treatment.
Figs. 1 to 6, refer to the making of a convex part of a case of which part Fig. 13 is
a section. Figs. 7 to 12, refer to the making of a brooch block. Similar letters
denote similar parts wherever occuring. I provide two dies, an upper one a and a
lower one b. The lower one b is preferably made of steel or other suitable metal, and
the upper one of the same material or of one of a softer kind, such as brass. The
die bis furnished with holes c for the reception of pins or projections d provided
on the die a, in order that by inserting the pins d in the holes c, the two dies can be
put and kept in register and in the proper relative position to one another. The
die a has salient portions e thereon corresponding in size and shape to the required
inner surface f of the piece of pasteboard or other material g when it has been
operated on, and the lower die b has intaglio portions therein corresponding in size
and shape to that required to be given to the second surface i of the pasteboard or
other suitable material when finished. It will be obvious that the intaglio part h
of the die 6 must be larger and deeper than the salient parts e of the die a, so as to
accommodate the pasteboard or other material g when pressed between them. The
intaglio parts h are surrounded by an upstanding knife like cutting edge; or with
more than one such edge. The actual cutting edge is coincident with the outline of
the intaglio, and is also level with the upper surface k of the lower die b. The metal
surrounding is sloped downwards so as to form a hollowed out or lowered portion l, the
bottom of which is below the upper surface of the die b. The object of the lowered
part is to receive the trimmings of material cut off by the edge j. When the die a

page_text: is placed over b with its pins d in the holes c, the non salient.part m of the die a is
coincident with the top of the die 6 and with its cutting edge j. In use the dies
are heated, the paste board or other material of convenient size placed between them,
and the whole submitted to pressure, the moisture in the pasteboard or other
material preventing the tearing asunder of its fibres. When cut out portions are
required, such as the slot in brooch blocks, (articles used for the display of brooches
in shop windows & elsewhere, the slot receiving the pin) a suitably situated cutting
edge or cutter n may be provided on the die a and a slot o in the die b or
vice versa, and in such cases a groove p may be provided in the under side of
the bottom die, or the upper side of the upper die, as the case may be, to
prevent the cut out parts clogging the slots. Material after treatment with these
dies presents clear cut sharp edges q and a true level surface r all round, and this
without the necessity for any after treatment by scissors, filing, sand-papering, or
other like operations.
I do not confine myself to the precise shapes, relative positions, dimensions, or
other details described in the above Specification and exemplified in the accompanying
drawings, as considerable variation is possible without departure from the essential
features of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
CLAIMS.
1. For use in the manufacture of cases or parts of cases and the like for holding
and displaying jewellery and other articles, an upper and a lower die between which is
pressed the pasteboard or other material from which the part is to be made, one of the
said dies having salient portions corresponding to the required form of the inner
surface, and the other die having intaglio portions corresponding to the required
form of the outer surface of the piece of material to be operated on,
the intaglio portions being surrounded by an upstanding cutting edge which when
the two dies are pressed together, will be coincident with the non-salient surface
round the salient part or parts of the other die, the whole substantially as described
in the above Specification and exemplified in the accompanying drawings.
2. Providing dies such as are the subject matter of the above claim with cutters or
a cutter, and with slots or a slot, for use in cutting slots in any of the parts of the
material under treatment, substantially as described in the above Specification, and
exemplified in the accompanying drawings.
3. The improved method of forming cases or parts of cases for the holding and
displaying of jewellery and the like, by pressing the material from which such parts
are formed, between two dies, one of them having salient, and the other intaglio
features, and one of them being surrounded by an upstanding cutting edge,
substantially as described in the above Specification, and exemplified in the
accompanying drawings.
