COMPLETE SPECIFICATION.
Improvements in the Manufacture of Medals, Medallions, and the
like, and in the Materials employed therefor.
I, HENRY GRUEBER of 37 Snow Hill, London E.C., Die-sinker, 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 the manufacture of medals, medalets,
medallions, tokens, memorial and other tablets, and the like, and as for its objects
a method and means of construction whereby precious or expensive metals may be
employed in the manufacture of same at a cost but slightly in excess of that
involved when such articles are made. of base metal or alloy of metals as hitherto,
and I attain this by constructing such articles hollow in the first instance, which I
effect by the employment of suitable moulds, dies and blocks, and by the aid of
these produce an outer shell or casing of very thin sheet metal, which may be
silver, gold, or aluminium, or any desired combination of these, and the interior
or hollow portion of such shell or casing I fill in with, or cause to be occupied by,
any suitable solid and malleable substance, which may be cardboard, millboard,
lead, pitch, or any adaptable equivalent therefor, and when (by the aid of suitable
and well known tools suitable for the purpose) the said outer casing or shell has
been caused to cleanly and neatly enclose and hide the said filling, I place the
whole between a pair of suitable dies, and thereby produce. upon either or both
faces thereof, in bold relief, any desired subject, or subjects, which may be that of
the portrait of some illustrious person or persons upon one face, and the particulars
and date of some notable event to which their presence relates, upon the other face,
or either or both faces may contain an advertisement, or one an advertisement and
the other a calendar for the current or any subsequent year, or the like.
In order that my invention may be clearly understood reference may be made to
the accompanying drawings, in which,
Figs. 1, 2, 3 and 4 are sections of a medal, medallion or the like at different.
stages of its manufacture, illustrating one method of construction, according to my
invention.
Figs. 5, 6 and 7 are similar sections- illustrating a second or alternative method
of construction according to my invention, while Fig. 8 is an enlarged plan view of
Fig. 5.
Fig. 9 is an enlarged plan view of either face of a finished medal or the like,
constructed upon the method illustrated by Figs. 1, 2, 3 and 4, after such medal.
has been stamped on both faces.
Figs. 10 and 11 are views similar to Fig. 9 but pertaining to Figs. 5, 6, 7 and 8,
but in so far as relates to the reading or other matter contained thereon applies
equally to Figs. 1, 2, 3 and 4.
Referring to Figs. 1 to 4 and Fig. 9, for the purposes of my invention I procure
a disc of very thin metal, which, to facilitate description we will presume to be
aluminium, and preferably circular, and by the aid of a suitable block and core I
press this into the form of a dish or cup A, a section of which is shewn by Fig. 1,
and in this I place a block B of cardboard or any other of the substances previously
named or their equivalents, as shewn by Fig. 2, and upon this I place a disc of
thin metal C, as at Fig. 3, which may be the same as, or other metal than, that
of A, I then place the whole under a suitable tool by which the upper edge a of
the sides of A may be turned over towards and upon the dise C, thereby producing
Fig. 4, which then place between a pair of suitable dies, in which has been sunk
the matter to appear in relief on both faces of the medal or the like, thereby

page_text: producing a finished medal as at Fig. 9, having in every way the appearance of
being made of solid metal.
By the second method of constructing such or similar articles according to my
invention amenabled to employ two like or disimilar metals, preferably the
latter, in which may employ a dark metal, say gold, in the formation of the rim,
while white or lighter metal, say silver, or aluminium, may be used to form the flat
surfaces. I carry this arrangement into effect. by first forming of the said dark
metal the cup or dish A Fig. 5, by the sanie menus as that for producing Fig. 1,
and in this cut away a central opening, leaving only the sides a and a rim like
portion of the bottom, as shewn by in Fig. 8, which is an enlarged plan view of
Fig. 5, and in this 1 place a disc of the said white metal C, and on this the filling B,
and on Ba disc of white metal C as shewn in Fig. 6, and then turn over the top
edge of a on to C as in the previous method, saving that in this case the height
of a above C would be such as to provide ncounter part of when turned
down upon C as stated, and shewn by Fig. 7, and by the use of the same or similar
or other dies ns that before mentioned, I produce upon the flat or white metal
surfaces the matter in relief required. An example of a finished medal or the like
according to this method is shewn by Figs. 10 and 11.
I wish it understood that I may produce the articles named in any size, shape or
contour desired, and may employ any metal or combination of metals in the
formation of the external portions of same, and use any suitable material as a core
or filling therefor, without departing from the principle of my 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.
1st. The construction and use of hollow medals, medalets, medallions, tokens,
tablets and the like, and the employment of aluminium, gold, silver or other metal,
or any desired combination of these, in the production of same, and any suitable
material as a core or filling therefor, connected and combined substantially as
herein described and shewn.
2nd. In the construction of hollow medals and the like, the method of first
producing a cup or dish A, in which is inserted a filling of any suitable material B,
surmounted by a disc C, the two latter being enclosed or retained in position by
turning down the edge a of A, the whole being subsequently placed between
suitable dies for producing upon either or both faces thereof in bold relief, any
desired design, portrait or portraits, reading or other matter, substantially as herein
described and shewn by the accompanying drawings.
3rd. In the construction of hollow medals and the like, the method of first producing
a cup or dish A., having the central portion thereof removed for the formation of the
rim like portion b, upon which is placed a disc C, and upon this a block or filling
of any suitable material B, surmounted by a disc C, the three latter parts being
enclosed or retained in position by turning down the edge a of A, the whole being
subsequently placed between suitable dies for producing upon either or both faces
thereof in bold relief, any design, portrait, or portraits reading or other matter or
advertisement, substantially as herein described and shewn by the accompanying
drawings.
