PROVISIONAL SPECIFICATION.
Improvements in Devices for Holding Together and Supporting Parts
of Coffee-making Machines and other Vessels.
I, GEORG BAUMANN, of Amberg, Bavaria, Imperial Counsellor of Commerce, do
hereby declare the nature of this invention to be as follows:-
According to this invention there is provided a device which, as shown in Fig. 5
of the accompanying drawings, consists of an annular wire spring f furnished
in the middle and at the two ends with hooks or projections f₁ and f" which are
formed by bending the wire of which the spring is made and which engage in
lateral openings o made in the walls of the parts of the vessels, and there extend
inwardly and outwardly.
The parts of the hooks or projections extending from within outwardly serve
to hold fast in vessels covers d or top pieces a, while the parts of the hooks or
projections extending inwardly are intended at the same time to clamp or jam
n. and to carry loosely inserted sieves or intermediate bottoms or trays.
Such devices are applied to the upper part of a coffee-machine represented in
Figs. 1, 2, and 3 of the accompanying drawings (1) for holding fast the cover d
(see the unner part of Fig. 1, where the cover d is shown as held fast in the top
by the spring f): (2) for holding fast the top piece a in the lower part u (see the
lower part of Fig 1, where the top piece a is shown as held fast in the coffee
pot u); and also (3) for clamping or jamming in and carrying the sieves in the
lower end of the top piece a.
"
To put such a device in place the middle hook f" of the spring f is hooked or
inserted into an aperture o made in the wall of the part of the vessel, whereupon
the two end hooks fl can be easily passed one after the other into the correspond-
ing holes from inside outwardly.
Such devices are of particular value for enamelled parts of vessels. The several
parts which form all together one vessel--such as the cover d, the top piece a, and
the pot u of the coffee-machine illustrated-are not always exactly uniform in
diameter, the lavers of enamel differ in thickness, and the parts become warped
in the fire, so that a certain diametral play of the several parts must be had in
view in the manufacture; the parts belonging to each other fit therefore for the
most part only loosely together where a tight joining would be of great advan-
tage
By devices as herein before described the several parts are firmly held together
in a very simple manner.
Fig. 4 shows a sieve the bottom of which is held fast by a wire spring
such as represented in Fig. 6. This wire spring differs from the spring repre-
sented in Fig. 5 only in the forms of the hooks or projections f¹ and 'f".

page_text: be performed, to. be particularly described and ascertained in and by the following
statement:-
According to this invention there, is provided a device which, as shown in Fig. 5
of the drawing, filed with my Provisional Specification, consists of an annular
wire spring f furnished in the middle. and at the two ends with projections f¹
and fi which are formed by bending the wire of which the spring is made and
which engage in lateral openings o made in the wall of a part of vessel to be held
in place, and there extend inwardly and outwardly.
The parts of the projections extending from within outwardly are designed
to hold fast in vessels, covers or top pieces a, while the parts of the
projections extending inwardly are intended at the same time to clamp or jam
in, and to carry loosely inserted sieves or intermediate bottoms or trays.
Such devices are applied to the upper part of a coffee-machine represented in
Figs. 1, 2 and 3.
(1) for holding fast the cover d (see the upper part of Fig. 1, where the cover d
is shown as held fast in the top piece a by a spring f); (2) for holding fast the
top piece in the lower part u (see the lower part of Fig. 1, where the top
piece a is shown as held fast in the coffee pot u by another spring f); and also (3)
for clamping or jamming in and carrying the sieves in the lower end of the top
piece a.
To put such a device in place, the middle projection f" of the spring f is
inserted into an aperture o made in the wall of the part of the vessel to be
secured, whereupon the two end projections f¹ can be easily passed one after the
other into the corresponding holes from inside outwardly.
Such devices are of particular value for enamelled parts of vessels. The several
parts which constitute one vessel-as the cover d, the top piece a, and the
pot of the coffee-machine illustrated-are not always exactly uniform in
diameter, the layers of enamel differ in thickness, and the parts become warped
in the fire, so that a certain diametial play of the several parts must be had in
view in the manufacture: the parts belonging to each other fit therefore for the
most part only loosely together where a tight joining would be of great advan-
tage.
By devices as hereinbefore described the several parts are firmly held together
in a very simple manner.
Fig. 4 shows a colander or sieve the bottom of which is held fast by a wire spring
such as represented in Fig. 6 This wire spring differs from the spring repre-
sented in Fig. 5 only in the forms of the projections f¹ and f¹¹.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
A device for securing or jamming in parts of coffee-making machines and other
vessels, such as covers, top pieces, bottoms of sieves or intermediate bottoms, con-
sisting in an arrangement of annular wire springs of having projections f¹ f" which
are formed by bending the wire of which the springs are made and which engage
in lateral openings o provided in the walls of the parts of the vessels to be secured,
substantially as described and shown in the drawings filed with my Provisional
Specification.
