Improvements in the Manufacture and Uses 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 present invention relates to improvements in the manufacture of medals,
medallions, tokens, souvenirs, memorial tablets, pocket date-calendars and the like,
and consists of certain improvements upon, and modifications of the methods of
manufacture, the material employed, and the uses to which such articles may be
applied, described and shewn in my previous Patent No. 12193 of A.D. 1894.
In order that my said invention and the improvements constituting the same
may be fully understood, I have bereunto appended a sheet of drawings of which,
Fig. 1 represents a circular piece of sheet metal prepared according to one
method of carrying my invention into effect.
Fig. 2 is a section of a moulded cup or dish formed of Fig. 1.
Figs. 3 and 4 are sections of the same and its filling during the process of carrying
my invention into effect.
Figs. 5 and 6 are examples of the obverse and reverse sides respectively of the
finished article which may be produced from Fig. 1, while 7 is an edge view of the
same.
Fig. 8 is a view similar to Fig. 1 but according to a second or alternative method
of construction.
Figs. 9, 10 and 11 are views similar to Figs. 2, 3 and 4, while Fig. 12 is similar
to Fig. 5, but all relating to Fig. 8.
Referring to Figs. 1 to 7 inclusive, I carry my invention into effect by stamping,
cutting or otherwise producing from any kind of metal or combination of metals,
precious or otherwise, but preferably aluminium, a disc A, which may vary in shape
and size according to the required shape and size of the article to be produced
therefrom, but to facilitate description it may be presumed that A is circular, and
in this provide a circle, or broken circle of small holes a, of such size as
to readily permit an ordinary domestic pin to be passed therethrough. The said
disc AI now subject to pressure between suitable dies or moulds, by which means
I turn up the edge of A all round upon (or thereabouts) the dotted line in Fig. 1,
thereby producing a dish or cup as at Fig. 2, with the holes a in the upturned
edge B thereof.
The cup or dish A is then placed between suitable dies (as suggested by dotted
outline in Fig. 2) upon which has been formed the required design, device, adver-
tisement or the like, or a date-calender for the current year, such as that shewn
by Fig. 10 of the drawings of my said previous Patent before mentioned, so that
when Fig 2 leaves the said dies, such matter would stand out in bold relief upon
the under surface of the bottom of A, an example of which is shewn by Fig. 5.
Within the cup or dish A, 1 now place a circular block or partial filling C, of
any suitable soft material such as felt or the like, and upon this I place a disc D
of aluminium or other metal, upon which the same or other device or matter
has been embossed by suitable dies, or printed or painted, with or without being
glazed, or engraved or otherwise produced, or in lieu of a metallic disc, D may

page_text: be a piece of looking glass, either plain, or upon which a like or other device
or advertisement or calendar has been etched by fluoric acid, a sand blast or
other means. The cup or dish A and its fillings, would now appear in cross
section as at Fig. 3, when, by the means of suitable and well known tools, the
upper edge of B would now be turned down upon D, thus producing Fig. 4,
which is the finished medal or the like, and would appear upon its obverse side,
say as at Fig. 5, and upon its reverse side, say as at Fig. 6, and if viewed
edgewise as at Fig. 7.
Thus either or both faces of the medal or the like may contain an advertise-
ment or other matter desired, or one an advertisement and the other a plain or
other looking glass, while the holes a in its edge permit pins to be inserted as
shewn in Fig. 6, these being held by the filling C, thus forming a pin cushion
and looking glass.
By a second or alternative method of construction, I remove a portion of the
centre of the plate A Fig. 1, and produce a plate A' Fig. 8, the aperture
formed by such removed portion being indicated by E, and in like manner_ [
treat A by suitable dies or moulds and produce Fig. 9, the upstanding edge B¹
having in like manuer pin holes a formed therein, and in the cup or dish A' I place
a disc of metal F upon which the desired advertisement, device, calendar or other
matter has been embossed, engraved, printed or otherwise produced, with or without
being glazed, and upon this I place a like filling C, covered by another metallic
disc or looking glass D prepared as described in the previous method thus
producing Figs. 10 and 11 respectively, the edges of B' being then turned down
upon D. as previously described, the result being a medal or the like such for
instance as at Fig. 11. In this arrangement the portion Fig. 8 may be of gold,
aluminium alloy, or other dark colored metal, while the disc F, and (if not of glass)
the disc D, may be of silver, aluminium or other light colored metal, the holes a in
the edge forming a pin cushion as in the previous method, and an example of either
side of this article is shewn at Fig. 12.
I wish it understood that although in the accompanying drawings I have chosen
to show my invention as circular, I do not confine myself to this or any other shape,
but may if desired form the same rectangular, polygonal or triangular in plan, and
of various sizes, with holes a in either or all of the surfaces of its edge, and I may
employ any desired combination of the materials stated other than in the manners
described 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
Ist. The construction of hollow medals, medallions, tokens, tablets and the like,
the employment of aluminium or other metal or combination of metals and looking
glass in the production of same, and the use of such articles for advertising and
other purposes, and as pin cushions or looking glasses or both, substantially as herein
described and shewn.
2nd. In the construction of hollow medals and the like, the combination of a
plate A, having perforations a, and the use of suitable moulds for forming of such a
plate a cup or dish as at Fig. 2, and the use of suitable dies for producing any
advertisement, design or other matter upon the outer surface of the bottom of
same, and the insertion therein of a filling C, of any suitable material, and a metal
disc D containing embossed printed or other matter, or a plain or other looking
glass D in lieu of metal, and the method of retaining C and D in position by
turning down the edge of the side B of A, substantially as and for the purposes
herein described and shewn.
3rd. In the construction of hollow medals and the like, the combination of a
plate A¹ having a central opening E and perforations a, and the use of suitable
moulds for forming thereof a cup or dish such as Fig. 9, and the insertion therein
of a metallic disc F having any design, advertisement, or other matter embossed,

page_text: printed, engraved, or otherwise produced thereon, or a mirrored glass in lieu of F,
plain or otherwise, the filling C of any suitable material placed upon F and
surmounted by a disc of metal or mirrored glass D, plain or containing au advertise-
ment or other matter, and the method of retaining F, C and D in position by
turning down upon the latter the edge of the side B₁ of A', substantially as and for
the purposes herein described and shewn by the accompanying drawings.
