Improvements in the Construction of Interior Partition Walls
and the like.
I, WILHELM BUCHWALDT of 54 Lobuschstrasse Altona-Ottensen in the Empire
of Germany 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 the construction of light walls such as are usually made
on a framing of timber or otherwise by use of laths fixed thereon and covered with
plaister for the division of the interior of a building into rooms or like purposes, and
it consists in an improved construction of wall hereinafter described to be used in
place of such timber framed partition walls or the like.
Between the floor and the ceiling are placed vertical posts of iron or steel, Hat
in cross section and turned over at right angles at each end and secured by wood
screws to the ceiling and floor respectively. These posts are flat in cross section
and are so placed that they stand with their greatest breadth transversely to the
general plane of the partition wall of which they serve as the framing.
The laths or equivalent holders for the plaister as at present used are fixed
horizontally along the line of these posts at suitable distances apart parallel to
each other, being supported by wires slung from hooks at the ceiling and passing
alternately behind and in front of the laths down each side of the aforesaid posts.
The laths on the one side of the posts are also bound securely towards the posts
and also the laths on the other side of the posts by other wires passing from the
ceiling in front or outside of several of the laths on the one side, thence outside
The
several on the other side and so on in a zigzag manner towards the floor.
plaister is laid on the wall in the usual way.
The annexed drawings in connexion with the following description will illustrate
the method of carrying this invention into practice;
Fig. 1 being a cross section through the partition,
Fig. 2 a side elevation of the wall in course of construction.
Fig. 3 a detail view on a larger scale in side elevation.
Fig. 4 the same in cross section.
The posts a with their ends a' bent over at right angles and secured by screws
passing through them into the floor and ceiling joists are placed about two feet
apart and along the line of the posts hooks or strong eyelets m are fastened
in the ceiling joist to carry the wires n and o. Reeds are shown as used instead
of laths and the wires n by winding in and out between them as seen secure them
each to each at distances apart equivalent to those usually employed.
Each wire or pair of wires may be about 6 inches from the next.
are arranged near the posts only and pass around several of the reeds or laths on
each side alternately so as to bind them securely together and therefore against
the posts. The wires n and o are fastened at their lower ends to hooks or eyelets m³
in the floor. The framing thus constructed is ready to be served with the plaister
in the usual way.
The wires o
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 ;-
The improved construction of partition walls and the like of a series of posts of
iron, steel or convenient metal fixed at intervals substantially as described and

page_text: regard to the posts by wires fastened to the ceiling and floor substantially in the
manner set forth for the reception of the plaister in the usual way.
