I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors 6 Lord Street, Liverpool, and 6 Bank Street, Manchester,
both in the County of Lancaster, and 323 High Holborn in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
As is well known rays of light have a bad effect upon beer, as they spoil the
taste of the beer and therefore vessels of transparent glass are not the most suitable
for containing beer. Vessels of earthenware, porcelain and other opaque substances
on the other hand are disliked by beer drinkers in many places as they cannot
examine the contents of the vessel to see its colour and purity.
The drinking vessels (more particularly beer glasses) forming the object of this
invention have neither the disadvantage of the vessels made of transparent glass
nor yet of those opaque beer mugs made of earthenware, porcelain, etcetera.
These beer glasses are in fact made in two parts and consist of an upper part or
casing made of light opaque material such as ground glass, opal glass, dark coloured
glass, porcelain, etcetera, whilst the bottom consists of transparent material such as
transparent colourless glass, rock crystal, etcetera.
The bottom piece can either be formed in one piece with the upper part or
casing, or it can be cemented on or be smelted on by means of molten glass, or the
bottom piece is flanged and cemented all round the casing, or for strengthening the
connection between the bottom and the sides a metal ring is fastened on all round,
and this connection is rendered more perfect by means of cement.
These beer glasses owing to the make of casing do not allow the rays of light to
penetrate into the interior, if, finally, an opaque cover be placed on the top, but on
the other hand, by lifting the glass up from the table owing to the thoroughly
transparent bottom, the contents of the same after lifting the lid can be examined
as to colour and purity.

I, WILLIAM PHILLIPS THOMPSON F.C.S. M.1.M.E. of the Agency for
Foreign Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster, & 323, High Holborn in the
County of Middlesex, Civil Engineer 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 :—
This invention has reference to drinking vessels more especially designed for
D

page_text: containing beer and the like liquids, and the improvements consist in a beer
receptacle capable of protecting its contents from the deleterious effect of the sun-
light and yet of admitting the ready determination of the colour and comparative
clearness of the beer.
In the accompanying drawings forming part of this Specification:-
Figure 1 is a vertical sectional view of the improved drinking vessel.
Figure 2 is an inverted plan view of the same.
Figure 3 is an exterior view, partly in section, showing the marking places as
hereinafter specified, and
Figure 4 is a plan view of Figure 3.
It is a well known fact that sun-beams have a prejudicial influence on beer,
spoiling its flavour, and otherwise impairing it, and hence it is that glass vessels are
objectionable for use. Vessels of earthenware, porcelain or other opaque material
are not universally popular with beer drinkers, since the purity and colour of the
beer cannot be examined through the wall of the vessel.
Vessels made in accordance with this invention have neither the disadvantages of
the common beer glass, nor those of the ordinary earthenware, porcelain and like
receptacles.
As shown in Figure 1 of the drawing, the vessel consists of two parts, the upper
part A being of an opaque material, such as opal or other coloured glass, porcelain
and the like, which constitutes the body of the vessel; and the part B of
transparent material forming the bottom of the vessel.
When the
The opaque character of the part A prevents the sun's rays from penetrating to
the contents of the vessel, the rays being totally excluded when the vessel is
provided with a hinged lid C of some opaque material, such as metal.
vessel is elevated and the lid C raised the light will be so reflected vertically
through the same, that the colour and purity of the contents can be readily
determined.
It will be obvious, that the parts A B though of separate materials, may be
secured together, for instance, by a cementation or annealing process and so the
vessel may be made in one piece, the walls being rendered opaque during or after
the process of manufacture.
•
In order that customers in taverns and public rooms may recognise their own
drinking vessels, there are provided, as shown in Figure 3, in the opaque parts of
the vessel, the body or the top, places a or a¹ with dull and rough surfaces. The
customer, with lead-pencil, crayon, ink or colour may make a mark on this rough
place which can afterwards be wiped off. In this manner the customer is certain
of always receiving the same vessel.
The marking places a or a' may be of any suitable shape; they might even be
made in the form of a band around the body of the vessel.
Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. A drinking vessel having an opaque body and top, and a transparent bottom,
substantially as set forth.
2. The combination in a drinking vessel, of an opaque body and a transparent
bottom, together with a top or lid of opaque material, substantially as set forth.
