page_text: I, NICOLAUS CHRISTIAN ROHWER, of No. 3 Höchste Strasso, in the City of Berlin
in the Empire of Germany, Engineer do hereby doclare 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:-
My invention relates to improvements in extensible tables in which the extra leaves
are so arranged beneath the permanent leaves that the same lie partly side by side and
partly one above another when the table is closed and are connected beneath the table
proper by means of suitable rails so that when the table is extended the reserved
leaves can be raised to the level of the permanent leaves by a lover combination. Two
or more leaves connected to the sliding rails are arranged above the permanent leaves
which, when the table is extended, will lay themselves flush with the permanent
leaves and thus increase the length of the table without rendering the construction of
the table more complicated.
In the accompanying drawings,
Fig. 1 is a longitudinal section of the table, one half of which is extended.
Fig. 2 is a vertical transverse section of a table with the extra leaves pushed beneath
the table.
Fig. 3 is a top view of the table shown in Figs. 1 and 2.
Fig. 4 is a longitudinal section of a modification of the table represented in
Figs. 1, 2 and 3.
Fig. 5 is a top view of the table shown in Fig. 4.
Fig. 6 is a vertical transverse section of the table represented by Figs. 4 and 5, the
extra leaves being pushed beneath the table.
Fig. 7 represents, in longitudinal section, a part of the table with one of the
extra leaves arranged above the stationary leaves, the extensible leaf being partly
extended.
Figs. 8 and 9 represent a further modification of my improved extensible table,
Fig. 8 being a transverse and Fig. 9 a longitudinal section of the same, in which the
extra leaves are not connected to the sliding rails but are loosely placed on the same.

page_text: a are the permanent leaves of the table, the side frames b, b, being attached at the
upper edge to the leaves a, and at the lower side to the rails c, c, and enclose the
stationary guide rails d, d, so that a number of movable or extensible guide rails can be
arranged laterally to the stationary rails d, and guided in suitable grooves.
The extensible rails e, f, g, e, f, g, and the rails h, i, k, h¹, i, k¹, are so arranged
that when the table is extended the former are on the one side, the latter on the other
side of the rails d. Each of these extensible rails carries a leaf or flap or a half of
the same, which is drawn out when the rails are extended.
1, 1, are the half flaps or leaves arranged above the stationary leaves a and which,
in the construction represented in Figs. 1, 2 and 3, are connected to the rails e, e¹
or k, k, by means of the angle irons m or their equivalents.
Instead of employing half leaves, full loaves or flaps can be used which are located
one above the other on the stationary leaf or leaves, said leaves or flaps being so
connected to the guide rails that the same can be drawn out from both ends of the
table. When the parts are not extended the angle irons fit into suitable slots or
recesses n and thus firmly connect the movable flaps or leaves 1, 1 to the stationary
·leaves a.
'
In the construction represented in Figs. 1, 2 and 3 the movable leaves or flaps o
and p are connected on one side to the guide rails f¹g, whilst the other side is
supported by angle irons, not shown, fixed to the end rails or frame of the table.
The parts of the extra leaves are connected by suitable hinges so that they can be
folded together and be pushed between the guide rails, Fig. 2.
The flaps or leaves are connected to the guide rails by levers q, q, r, r, &
which
are arranged to turn in the guide rails so as to lift the leaves or flaps up to the level
of the fixed stationary flaps or leaves.
In order to attain an equal surface over the entire table the edges of the leaves or
flaps, and also the stationary leaves are provided alternately with dowel pins and
recesses as customary with extensible dining and other tables, or the edges can be
provided with angle irons in order to firmly hold the leaves or flaps.
:
The end rails of the table frame is connected to the guide rail and carries a narrow
flap or transverse rail t. When the extensible rails have been drawn out and the
leaves o, p, or o¹, pl, raised to the level of the permanent leaf a, the flap or rail t having
been drawn outward to allow the leaf p or p¹ to pass upwards, the said narrow flap
or rail t is pushed into snug contact with the leaf p or pl and the bolt u is so operated
that the same will occupy the position represented in Fig. 1 so as to securely grip the
flap or rail t and thus not only prevent all movement of the rail t but also servo to
securely hold the flaps or leaves in position.
The joints to the extra leaves can also be rendered rigid by means of suitable
bolts or slides.
According to the modification represented in Figs. 4 to 7, an extensible part with
appertinent extra leaf is omitted from both ends of the table in order to better
illustrate the construction. This said construction differs from the one hereinbefore
described in so far as the leaves p and p¹ are connected on both sides to the guide
rails g³, g³ and h², h³, by means of levers r, r, and 71, 7; this, however, necessitates
the cutting away of the lower edge of the guide rail d in order to permit of the metal
fittings of guides h2, h3 being connected with the extra leaves by the lever 1,
Fig. 4.
Fig. 7 represents the arrangement above the stationary leaves of an extensible leaf,
its connection with the corresponding guide rail and how the same is extended in
combination therewith.
Should it be desired to extend the table beyond the ordinary requirements, loose
extra leaves can be laid above the leaves connected to the guide rails which are drawn
out with the other leaves and can be laid loosely on the guide rails as usual.
An extensible table with loose leaves only is. represented in Figs. 8 and 9. The
leaves are laid in frames v and w, which are connected by angle irons x, y, fixed to
those rails which can be extended furthest.
•
In this modification half-leaves are also arranged on the stationary leaf or leaves

page_text: .
and are connected with the guide rails as described above. The fixed rails are in
this case also cut away as indicated by dotted lines in Fig. 9, in order to allow the
angle irons y to pass.
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. An extensible table consisting of extra leaves joined together by suitable hinges
and laid together with the guide rails beneath the fixed leaves a, so that when the
rails are drawn out, the extensible leaves can be raised by means of the levers
to the level of the stationary leaves, whereby the extra leaves are connected to each
other and to the rails on both sides, substantially as and for the purpose set forth.

2. In an extensible table, the arrangement of extensible leaves or half leaves on a
fixed table leaf a, which are so connected with the guide rails arranged laterally under
the said fixed leaf, that when the rails are drawn out the leaves or half leaves or flaps
can be turned sidewise and brought up to the level of the fixed leaf a, substantially
as and for the purpose set forth.
3. In extensible tables of the kind herein described, the modification whereby the
hinged leaves are substituted by loose leaves which may be placed in extensible
frames connected to the guide rails, substantially as and for the purpose set forth and
shown in Figs. 8 and 9.
4. The construction of my improved extensible table, substantially as described in
the foregoing specification and represented in Figs. 1 to 9 of the accompanying
drawings, or any mere modification of the same.
