This invention relatesto a method of making dummy sweetmeats'for display purposes such as imitations of assorted chocolates or other sweetsintended to be displayed in shop g; windows.

` An object of the invention is to enable such dummy sweets to be made as exact replicas of actual chocolate or otherl sweets so that it will be practically impossible to detect lo any difference, whilst the imitation sweets will be able to withstand exposure without deteriorating.

y Another object of the invention is to providefor forming a casting which is an exact l5 replicaof an actual chocolate or sweetmeat to be imitated and which is capable of use as Va die in forming'matrices to any required number exactly similar to one another, for

use in reproducing a' large number of imita- 'J tion chocolates or sweetmeats all ofthe same shape and pattern. i i

In lcarrying out the invention a cast is made from the actual sweetmeat by covering said sweetmeat with a setting paste or 5 composition; when `the cast has set the sweetmeat is removed` therefromV and, into the cavity in .the cast formed by removing the sweetineat is poured molten metal which, when set, forms a die which is removed from the cast. An elastic rubber matrix is vulcanized on the die, and after removing said matrix from the die it is inverted and filled with a setting paste or composition in order to form a dummy sweetmeat which is removed when set and suitably coated to imitate the actual sweetmeat. Y

0f the accompanying drawings which form a part of this specification Figure 1 is a perspective view of the actual sweetmeat to be imitated. Y

i Y Figure 2 is a verticalfsection through a mould showing how aplaster cast is made of the sweetmeat.

p Figure 3 is a perspective view of the plaster 45 cast inverted, after the sweetmeat has been removed therefrom. y

Figure 4 is a sectional viewA of a rubber matrix vulcanized on a metalV die which has been cast in the cavity of the plaster cast, and

"3' Figure 5 is a sectional view of the matrix shown inverted and fitted in a base, andfilled in order to form the dummy sweetmeat.

According to the invention the actual chocolateV or vother sweet 6 of a good design 'is' selected and placed centrally Withina shell7 so asl to rest on the same floor surface -as the-said-shell. lInto the shell 7 is poured a mixture of plaster of Paris and 'water of a suitable consistency or any `other suitable setting composition, so as to well cover the sweet 6.

Then thesaid plaster of'Paris, which is indicated by `reference 8, has set, the sweet 6 is removed by scooping it out ofthe plaster cast 8, or` melting it,'or in other lsuitable manner. Y

Y The plaster cast 8 is then arranged with its cavity 9, formedby removing the sweet, uppermost, and into the4 said cavity 9 is poured molten lead or other suitable metal sov as to obtain an exact `metal casting of the original sweet. y

This metal casting is carefully polished and serves as 'a metal die l0 (Figure 4) upon which -a rubber matrix ll'is formed and lvulcanized thereon, said rubber matrix being formed with a projectingrboss 12. The saidrubber matrix 11, when completed is removed from the metal` die lO and placed, with its cavity uppermost, on` a suitable base 13,the projecting boss l2`of said matrix being engaged in a hole 14 formed in the base 18 (Figure 5). The said rubber matrix ll serves as an elastic mould into which is poured a suitable composition of plaster of Paris or any other suitable setting composition, so as to completely lill the cavity thereof. SaidV filling l5 is removed when set,:the elastic nature of the rubber matrix allowing this to be done despite any external projections on said filling, and forms the actual reproduction or imitation chocolate or other sweet. Y

After thoroughly drying, the plaster imitation sweet is immersed in a bath of shellac `or other suitable liquid flatting to impart a coating to the plaster, and to form a ground for the reception of paint or other suitable colouring matter.

The cast shapes thus produced are coated luc meat.

with paint or other colouring matter to represent the original chocolate or sweet.

Where a plain chocolate or sweet is represented, the shapes may be actually dipped into the material which when dry will give a hard permanent surface so that the nished dummy sweet will have the -exact'appearance of a real chocolate or sweet.

In the case of sweetmeats other than chocolates the colour and nature of the coating material will be varied accordingly. Where the smeetmeets are of a fancy character they may be painted by hand to represent the original sweet. v

Imitation chocolates and other sweets constructed according to our invention may be cheaply produced in large quantities so as to exactly resemble the original chocolate or other sweet. They are of a permanent and durable character and will not deteriorate by exposure to light, heat or damp and are thus particularly suitable for display in shop windows and other places.

We claim A method of ymanufacturing dummy sweetmeats for display purposes consisting in making a cast from the actual sweetmeat by enclosing same within a shell, pouring into said shell a setting paste or composition and covering the sweetmeat therewith, subsequently removing the sweetmeat when the cast has set, moulding a metal die in the cavity in the cast formed by removing the sweetmeat therefrom, subsequently removing, the metal die, vulcanizing on to the metal die an elastic rubber matrix having an externally projecting boss, removing the die from the matrix, inverting the matrix and engaging the projecting boss thereof in a base, filling the inverted matrix with a setting paste or composition to form a dummy sweetmeat and subsequently coating said dummy to represent the actual sweet- TOM nnnnvefron'.
