Improvements relating to the Adjustment of Bedsteads, Seats, and
the like.
I, REGINALD HADDAN of the firm of Herbert & Co. Patent Agents of 18
Buckingham Street Strand W.C. London, Civil Engineer, do hereby declare the
nature of this invention a communication to me from abroad by August Dessauer
of Neuerwall, 28, Hamburg in the Empire of Germany, Merchant, 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 the frames of articles such as bedsteads, cots, seats and
stands of various kinds which it may be desirable to have adjustable either in
length or width, either so that they may take up less space when not in use or that
they may be adjusted to suit the person using them or the article or thing placed
upon them.
The accompanying drawing illustrates the invention as applied to a bedstead
adjustable in length.
Fig. 1 is a side elevation of the bedstead compressed.
Fig. 2 is a similar view partly in section of the bed extended.
Fig. 3 is a plan view thereof partly in section and
Fig. 4 is a cross section of part thereof.
The vertically supporting frames in the line of the desired adjustment are
composed as follows; an upper and a lower horizontal tube a a¹ are connected by a
central post m.
In the ends of the tubes a a¹ slide rods or other tubes bb b¹ b', one
at each end, the upper being connected to the lower at each end of the frame by a
post K.
To the two posts K K are pivoted, to each, two extension struts M M¹
and to the central post m are pivoted centrally two double struts M² M³ and the
latter are connected to sockets M' to which the ends of the struts M M M' M' are
also connected, these sockets sliding upon two rods oo the ends of which rest
Either of the end
against the tubes a a¹ and serve as additional supports therefor.
posts KK may be pulled out or pushed inwards and the other post and
corresponding parts will perform a similar movement.
The struts M M M² M³
support the framework whether extended or contracted or at any position inter-
mediate of full extension or contraction.
In such a bedstead to cause the under-frame to be extended or contracted
simultaneously with the vertical frames, the under frame is composed also of two
tubes d d connected by spring or other slats s or carrying such slats, and of sliding
rods or tubes d' d', d² ², connected by end pieces e. Hooked pieces el e¹ on the
end posts K K engage with the pieces e e while the central tubes d d may or may
not be engaged in a similar way with the central posts m m.
In applying the invention to a wall bed which lies with one side along a wall, or
to a ships berth, only one of the sides may be extensible as before described, that
is to say, need be constructed as the vertical frame before described. In applying
the invention to sofas, settees and the like, only one of the vertical frames here
described need be used.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is;-
1. An extension-frame for bedsteads, and other contrivances, comprising a middle
portion and two sliding end portions the latter connected to the former by a system
of struts pivoted upon the end portions and on the middle portion substantially as
herein described.

page_text: 2. An extension frame for the purposes set forth consisting of two tubes a a
connected by central post m. End posts K K having tubes or rods b',
struts M M M2 M3 connected to posts K K m and to sockets M' as described and
rods oo passing through said sockets.
3. The combination with an extensible vertical frame in three parts as described,
of an extensible horizontal frame comprising sliding parts d d d' d', d' d' connected
each to each by spring or other slats s and having hook like connections with the
three parts of the vertical frame whereby the two frames are simultaneously
adjustable substantially as and for the purpose described.
Dated this 21st day of March 1892.
