PROVISIONAL SPECIFICATION.
Improved Removable Lid or Cover for Drinking Mugs and other
Round or Angular Vessels.
A communication by FRANZ SAUERBIER, of 69, Lindenstrasse, Berlin, in the
Empire of Germany, Manufacturer.
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:-
This invention has for its object a lid more particularly intended for drinking
mugs, but which may be also employed for other vessels, and which is characterised
by its being able to 'be fixed without further trouble on the edge of the drinking
mug or other vessel by means of a clamp attached by means of a hinge to the actual
cover plate or lid, such clamp being either naturally springy or rendered so by
means of a spring. The attachment of this clamp takes place without it being
necessary to have any special connecting or attachment device on the glass or
vessel, or to make the latter of any peculiar form as regards projections,
attachments, etcetera.
This latter point, in particular, is of great importance for this invention; as, in
all cases where the attachment of the lid necessitates such a special form being given
to the glass or vessel, any re-utilisation of the lid in case of breakage of the glass
or vessel is only possible if a glass or vessel be provided of exactly the same
peculiar form. According to experience, the subsequent procuring of such glasses
or vessels which are distinguished by their unusual shapes is, however, generally
attended with great difficulty, and a disproportionately great expense, and mainly
for these reasons such glasses or vessels with removable lids have not come into
general use, whereas the advantages of such a removable lid, more particularly for
cleaning purposes in the case of drinking vessels, are indeed indisputable.
Removable lids indeed exist which may be attached to suitably shaped or smooth
glasses, but with these lids always special attaching devices are necessary, which
must be first operated by hand. As a rule, screws are employed which must first
be each time tightened or loosened. The wearing out of the threads very soon
makes the whole arrangement insecure; single screws are also easily lost, and the
whole arrangement is unsightly and inconvenient.
All these drawbacks are completely removed by this improved device. This
improved lid may, without further difficulty, be placed on any suitable glass of
corresponding width, and also removed with equal facility.
The lid is connected by means of a hinge with a clamp. This clamp has a
suitable round or straight form, according as it is intended for a round or angular
vessel, and is placed over the edge of the vessel. The clamp is made of some
suitable material, such as, for instance, sheet metal, vulcanite, celluloid, etcetera,
which insures a natural spring grip of the two jaws or cheeks, so that the spring
action exerted by these latter being of a suitable form, when clamped or stuck on
the edge of the glass, insures a firm hold of the clamp thereon, so that the lid,
when the glass is in use, may with safety be opened or closed, whilst, on the
other hand, in order to allow of the glass being conveniently cleaned, it only

page_text: requires a suitable amount of force to again remove the clamp and lid from the
glass without further trouble.
As already herein before stated, without at all departing from the essential
feature of the invention, the form of construction of the clamo may be modified by
the cheeks or jaws being made with a separate spring instead of being made of a
springy material. In such case, one cheek or jaw of the clamp, for instance the
outer one, is hinged, and is pressed against the side of the glass by means of a
spring. The hinge of the lid is, in this modified form of construction, preferably
arranged in the centre of the bar connecting the two cheeks or jaws. If the
removable lid hereinbefore described is intended to be employed for angular
vessels, which are somewhat larger in dimensions, two or even more straight clamps
of either kind may be connected with the lid plate.

Improved Removable Lid or Cover for Drinking Mugs and other
Round or Angular Vessels.
I WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of The Agency for
Foreign Patent Solicitors 6 Lord Street Liverpool & 6 Bank Street
Manchester. in the County of Lancaster and 31 High Holborn in the County
of Middlesex Civil Engineer a communication from abroad from Franz Sauerbier,
of 69 Lindenstrasse, Berlin, S.W. Germany Manufacturer 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:---
The lid or cover (a) with the hinge (b) and the elastic spring clasp (c), as per
drawings herewith, serve to effect a temporary protection against the introduction
of dust into beer-mugs and other vessels. The clasp (c) forms part of a circle whose
radius agrees with that of the vessel to be covered, and consists of 2 flexible clips
arranged in a manner to facilitate the fastening of the lid or cover to any point of
the rim of the vessel. The hinge b with its clips e being firmly secured to the
vessel by the force of the springs the lid can be opened by pressing back the
knob d.
The device may be manufactured of metal, india rubber, celluloid, or other
material.
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 :
1. Fexible clips adapted to the form of the vessels, as supporting mechanism for
removable lids or covers.
2. The combination of the clips, set forth in Claim 1 with a lid or cover and a
hinge, connecting the same for the purposes described.
