We, CHARLES KOBABE and LOUIS KUPHAL, trading together as Kobabe &
Kuphal, of Summer Row Birdcage Works, Birmingham, Warwickshire, Birdcage
Manufacturers, do hereby declare the nature of this invention to be as follows
This invention has reference more, particularly to those parrot cages, and other...
like bird cages which are formed of upright or inclined wires passing through and
secured together by hollow metal rings at certain intervals apart, the upper, ends, of
the wires being bent over towards each other to form the top of the cage and
secured to a central plate or boss..

Héretofore it has been customary to make these cages of tinned wires secured to
the metal rings by soldering but by this invention we are enabled, to make the said,
cages of untinned wire and then to tin the cage when framed together which makes..
the cages. much stronger, than heretofore and enables them to be produced at a
lower cost.
.
.
In carrying out this, invention we make the cage of the usual form with untinned
upright or inclined wires passing through hollow metal rings of the usual bollow;
section. We make each of these rings of an inner and an outer channel section
ring fitting one within the other, but instead of securing these two channel section
rings together by soldering, as heretofore, we swage or fold their edges together to
prevent their coming apart when, dipped in the molten metal. We also provide a
series of small holes in each ring to enable the molten tin to run into and out of the
hollow rings and thus effectually secure the wires thereto. In order to secure the
upright or inclined wires to the hollow metal rings before and during the immersion
of the bird cage in the molten tin, some of the wires are indented or bent where
they are enclosed in the rings thus keeping the rings at the proper distances apart.
This is done before the outer rings are fixed to the inner rings. The ends of the
channel section strips forming the said rings have to be secured, together, by rivets
or by folding.or other means than soldering so that they will not come apart when
dipped in the molten tin.
Another important feature of this invention is the method of constructing the,
central boss at the top of the cage to which the ends of the wires are secured and
this is applicable to those parrot and other bird cages which are formed wholly of,
wire as well as to the kind above described. We, employ two circular plates one.
above the wires and one below, the same between which the ends of the wires pass
one of these plates, has,.or both,,of these plates have, projections around the edge.
which are turned up between the wires, and closed, over the other plate, thus securing
the two plates together and, to the wires, and the latter. at the proper distances
apart. The wires and the plates. are or may be then firmly, secured together by
the tinning process...

Improvements in the Manufacture of Parrot Cages and other like
Bird Cages.
WC, CHARLES KOBABE and LOUIS KUPHAL, trading together as Kobabe and
Kuphal, of Summer Row Birdcage Works, Birmingham, Warwickshire, Birdcage
Manufacturers, 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 more particularly to those parrot cages and other
like bird cages which are formed of upright or inclined wires passing through and
secured together by hollow metal rings at certain intervals apart, the upper ends of
the wires being bent over towards each other to formn the top of the cage and
secured to a central plate or boss.
Heretofore it has been customary to make these cages of tinned wires, secured to
the metal rings by soldering, but by this invention we are enabled to make the said
cages of untinned wire and then to tin the cage when framed together which-makes-
the cages more stronger than heretofore and enables them to be produced at a
lower cost.
We will describe this invention by referring to the accompanying sheets of
drawings on which
Fig. 1 represents in elevation, Fig. 2 in plan and Fig. 3 in vertical cross section
part of one of the hollow metal rings of a bird cage constructed according to this
invention with the inclined wires fixed thereto;
Fig. 4 shews in clevation, plan and cross section part of the inner channel-section-
ring and
Fig. 5 shews similar views of part of the outer channel-section ring of which the
said hollow ring is formed;
Fig. 6 shews in plan and Fig. 7 in sectional elevation the central boss of the top
of a bird cage constructed according to this invention and parts of the wires which
are fixed thereto; and
Figs. 8 and 9 shew separately the two plates forming the said boss.
It
In carrying out this invention we make the cage of the usual form with untinned
upright or inclined wires passing through hollow metal rings of the usual hollow
section. We make each of these rings of an inner channel section ring a and an
outer channel section ring (see Figs. 1, 2, 3, 4 and 5) the inner ring a fitting
inside the outer ring b as is usual, but instead of securing these two channel section
rings together by soldering as heretofore, we swage or fold their edges together (as
shewn in Fig. 3) to prevent their coming apart when dipped in the molten tin.
will be seen by Fig. 3 that the wires pass through holes in the inner ring a as
usual and that the edges of the outer channel section ring bare swaged or folded
down upon the edges of the inner ring a so as to secure the two rings together. In
the ring a (or in both of the rings) and preferably at the lower side thereof we
provide a series of small holes d to enable the molten tin (when the cage is dipped
therein) to run into and out of the hollow rings and thus effectually secure the
wires thereto. In order to secure the inclined wires c, or vertical wires, to the
hollow metal rings (which are formed by the channel section rings a b) and keep
the said hollow rings in place on the wires and at the proper distances apart before
and during the immersion of the bird cage in the molten tin, some of the wires (say
about every fifth wire) are indented or bent, as at c' Fig. 1, where they are enclosed
in the rings thus keeping the rings at the proper distances apart. This indenting
or bending of the wires c is done before the outer rings bare fixed to the inner
rings a. The ends of the channel section strips forming the channel rings a and
have to be secured together by rivets or by folding or by other means such as by
being bound together by thin wires instead of by soldering as is usual, so that they
will not come apart when dipped in the molten tin.

page_text: Another important feature of this invention, illustrated in Figs. 6, 7, 8 and 9, is
he method of constructing the central boss at the top of the cage to which the
apper ends of the wires are secured and this is applicable to those parrot and other
eird cages which are formed wholly of wire as well as to the kind above described
which are made of wires and metal rings in combination. We employ two circular
lates marked respectively e and f the plate e being above the wires and the other
late below the wires, the ends of the latter are therefore enclosed between
the plates e and f. The lower plate has projections." around the edge which are
urned up between the wires c and closed over the upper plate e thus securing the
wo plates together and to the wires and the latter at the proper distances apart.
Or projections such as f¹ may be formed round the plate e; or some of them may
be on the plate e and some on the plate and be turned down over the other plate
is above described. The wires c and the plates e andare or may be then firmly
secured together by the tinning process.
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 :-
The improvements in the manufacture of parrot cages and other like bird cages
hereinbefore described and illustrated by the accompanying drawings so as to
enable the said bird cages to be framed together without soldering and then tinned
afterwards the said improvements consisting in :-
(a) making each of the hollow horizontal rings through which the wires pass
of two channel section rings swaged together, one or both of the said rings
being perforated to allow of the molten tin running in and out and one or
more of the wires being indented or bent where it is or they are enclosed
in the ring or rings; and
(b) making the central boss at the top of the cage of two plates (such as e and f)
one above and the other below the wires, one or both of the said plates having
edge projections which are bent between the wires on to the other plate so
as to secure the plates together and to the wires and the wires at the proper
distances apart, substantially as hereinbefore set forth and illustrated by the
accompanying drawings.
