Improvements in Telescope Tables.
I, AUGUST NOSTER of 8 Barntherstrasse, Berlin in the Empire of Germany,
Joiner, 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 relates to telescope tables and it has for its object to dispense
with the ordinary extension mechanism and without additional legs to provide a
table which is capable of having its top extended to three times the initial length
and that without the use of removable leaves the top being made in sections which
fold over each other.
Fig. 1 is a plan of the table with the top removed and as ordinarily opened.
Fig. 2 is a section of a detail at an enlarged scale of the table on line A, B, of
Fig. 1.
Fig. 3 is a complete cross section of the table on line A, B of Fig. 1.
Fig. 4 is a longitudinal section of the table on line C, D of Fig. 1.
Fig. 5 is a longitudinal section of the table fully extended on line E, F.
Fig. 6 is a plan of the table fully extended. (In Fig. 5 the central of the table
top is removed.)

The table consists of two similar parts each supported on two legs and engaging
centrally together by groove and feather when the table is in its reduced form.
The frame of the table consists as in ordinary tables of a wooden rectangular
frame a, a stayed by cross bars and supported or carried by the feet of the table.
Inside this table frame a are arranged two pairs of bars 6 which are not connected
with the side walls but are connected in pairs one pair to each end of the table.
The bars 6 rest upon a ledge or grooved guide d which is so formed that the bars b
can slide along this ledge d and by forming its projecting parts on the outer sliding
bars b is as shewn reduced in half its length for a purpose hereinafter described.
The supports d which are connected by cross struts e and the middle piece c serve
to receive the bars b. This arrangement has for its object to connect together the
separated or divided halves of the table and to support the plate of the table. To
ensure the accurate sliding of the sliding bars b there is fixed on the middle pieces c
metal plates p the web of which projects into the bars b.and engages thereat over
the flat iron rails 7 of the bars b, b. The travel of the withdrawn leaves kis limited
by the pieces p striking one against the pieces on the bars b. The top or upper
plate of the table consists of three parts, the middle part i forming the real top
when the table is reduced to its shortest length. The other plates k serve as
leaves or flaps to extend the table and are concealed under the table top i when
the table is reduced. Each plate k consists of two folding parts or plates k, k
hinged together and which can be unfolded when extended to form the prolonga-
tion of the table. Each half of the table has one pair of bars 6 which in the one
case are arranged and move between the sides of the frame a and the middle bars c
while in the other they are arranged within the middle bar c. Owing to this
arrangement these sliding rails can extend along the whole length of the
table and hence it is possible to extend the table at each end a length equal
to its own. Sliding rails 9 are provided to prevent the flaps from hanging down
and wooden supports o are fixed to the frame b to afford the required hold to these
sliding rails g, while allowing the table to be moved without the extension plates
being disturbed. To guide the sliding rails 9 they are provided with an iron plate S
sliding in a corresponding groove of the bar b. Owing to the wooden supports o
of this sliding plate, the table can be lifted by its withdrawn leaves and carried
about. The central plate i is provided with iron pins m which engages with iron
027

page_text: bushes n fitted in the bars or pieces c in order to secure the table in its position.
The sliding rails engage by the aid of a wooden or iron bar h screwed thereon the
projection of the sliding bars b for the purpose of preventing the extension flaps or
leaves from being lifted out. The bars are reduced from the centre so as to
have cross sections of two thicknesses and hence make room for supporting blocks q.
These supports are secured to the frame by pins u and have at the top an elliptic
step or cut out form, being provided below with a notch the rear edge of which is
larger than the front edge. The purpose of these under supports is to afford a
proper hold for the extended and folded up table extensions, leaves or flaps k. The
operation of the same is automatic and is effected by a mere pulling out motion.
When the table is closed these supports bear longitudinally close against the bars b
while the notch is acted upon by the sliding bars g. The bars g. are furnished at a
determined distance from their ends with a stop h which when the plate or flap kis-
drawn out raises, the support q, but when the flap k is pushed, in knocks the plate h
on the bar g against the longest edge of the supporting blocks 9, and thereby folds:
the same into position. To prevent the supports q from dropping over, and to
ensure the perpendicular position of the same, pins vare inserted in the frame.
The upper part of the supports 7 has a step-like recess in which is located the
middle and thickest table top. while the folded over plate bears upon the
game.

In order to be able to use the table full length it is first necessary to separate the
table frame a which is connected as above stated by the inner sliding bars c and d.
Then the extensible flaps k, k, are drawn out causing the supports or blocks 9 to be..
raised in order to support the central table top. i. After the plates or flaps have
been fully withdrawn they are folded or turned over and rest, likewise upon the.
under supports g. In this position they are held by the sliding wooden pieces o and.
the movable plates in such a manner that the whole table can be raised and
carried by these plates. The central table plate or top i is secured in position by
the pins m engaging in the bushes n while the withdrawn table plates or flaps k are
firmly fixed to their sliding. rails g.
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.A telescope table constructed with an independent frame, connected with pins
to the middle leaf of the table and provided with rails on which the slides of the
extending part of the table work, also, with bearers. to support the outer folding
leaves, substantially as hereinbefore described with reference to the accompanying
drawings.

2. In a telescope table the tumblers q, q constructed and operating substantially
as described with reference to the drawings annexed.
