Improvements in Guards. for: Drinking: Vessels.
We, ALBERT ROSENBERG, of 1, Bühnenstrasse, Theatrical Engineer,. and
JACOB LEOPOLD WALDAPFEL, of 73, Ehrenstrasse, Private Official, both of
Cologne on the Rhine, in the Empire of Germany, 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:-
Our invention relates to an improved guard for placing over the edges of
drinking vessels and it has for its object overcoming the risk of infection by
drinking out of a glass or other vessel already used by another person and possibly
not properly washed out or cleansed.
Our improved guard consists of a ring of any suitable material adapted to be
placed over the edge of a glass or other vessel.
In the accompanying drawing which illustrates our invention :-
Figure 1 shows a guard or protective ring A made of soft rubber or other
elastic material, and having one of its edges a thickened on the inner side. The
expansive property of this ring enables it to be drawn over the edge of a glass or
other drinking vessel of any. diameter until the thickened edge a bears upon the
edge of the vessel and thus constitutes a new edge as it were to the said vessel.
Figure 2 shows another method of applying the ring A. In this case the
thickened edge a is sprung over the edge of the glass or other drinking vessel and
the other part of the ring is then turned inwards so that it completely covers the
edge of the vessel. In this case it is not obligatory to make one edge of the ring
thicker than the other.
Figure 3 shows another form our invention may assume in which the ring A is
made of a double form of an approximate V-shape in cross section, the outer part
of the ring being preferably deeper than the inner part thereof. This ring may
be made of hard rubber or other suitable material and it is adapted to be slipped over
the edge of the vessel as shown. If the material of which the ring is made is not
sufficiently elastic to make an air-tight joint with the edge of the vessel an elastic
or flexible bead a¹ may be attached, either to the inner part of the ring as shown,
or to the outer part thereof, or to both parts.
By the use of this guard, the mouth of the person drinking will be kept out
of contact with the vessel, thereby diminishing the risk of infection in epidemic
diseases.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction hereinbefore described and illustrated by the
accompanying drawing, but that we hold ourselves at liberty to make such changes
and alterations as fairly fall within the spirit and scope of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
(1.) The improvements in guards for drinking vessels, substantially as hereinbefore
described and illustrated by the accompanying drawing.
(2.) Guards for drinking vessels, consisting of rings of elastic or non-elastic
material, either with or without thickened edges and adapted to be placed over the
edges of drinking vessels, as and for the purpose set forth.

page_text: (3.) Guards for drinking vessels, consisting of double rings of any suitable non-
elastic material having elastic or flexible beads on either or both edges, as and for
the purpose set forth.
