I, WILHELM BRANDT, of Osterode, East Prussia, in the Empire of Germany,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a method of fastening or securing metal sheets,
laths, strips or the like on rods, bars and the like for making fences, walls and
for building and other purposes without separate means of fastening. For this
object, sheets, laths or strips are used having a transverse spring action which
causes them to press with their edges on the bar or rod.
As an example two corrugated lath pieces are arranged on a bar, which laths
have a spring action of themselves and are provided with holes through which the
bar or rod is passed. These holes are however so bored that they do not exactly
lie in one plane with the edges so that when the bar is inserted a slight bending
of the spring lath is necessary. By this means the edges of the laths and the
edges of the holes are pressed against the bar and thus the lath itself is prevented
by the friction from shifting laterally.
The form of the corrugations or the made of bending may be of any suitable
kind so long as a spring action is produced thereby. Thus, for instance, a zig-zag
or angular form may be adopted which acts in a similar manner to the corru-
gated or waved form.
In order to render the spring action as strong as possible, the sheets or laths
are selected as narrow as possible and under some circumstances they are given
an S or Z form. These forms, however, in order to obtain a suitable pressing on
the bar, necessitate separate turned up pieces or projections or the like acting
against the pressure of the spring. Thus for instance the material to be removed
for forming the holes to give passage to the bars may be bent back or the free
edges may be provided with holes and the bars passed through these also. Other
suitable forms of construction of the laths may of course be adopted.

on Bars and the like for Building, Fencing and other purposes.
I, WILHELM BRANDT, of Osterode, East Prussia, in the Empire of Germany,
Merchant, 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 for its object a method of fastening or securing metal sheets,
laths, strips or the like on rods, bars and the like for making fences, walls, and
for building and other purposes without separate means of fastening. For this
object, sheets, laths or strips are used having a transverse spring action which
causes them to press with their edges on the bar or rod.
In the accompanying drawings,
Figure 1 is an elevation of such an arrangement; and
Figure 2, a cross section.
As an example two corrugated lath pieces L are arranged on a bar S, which
laths have a spring action of themselves and are provided with holes a through
which the bar or rod S is passed. These holes a are however so bored that they do
not exactly lie in one plane with the edges so that when the bar S is inserted
a slight bending of the spring lath is necessary. By this means the edges b and
the edges of the holes a, as indicated in Figure 2, are pressed against the bar
and thus the lath itself is prevented by the friction from shifting laterally.
The form of the corrugations or the mode of bending may be of any suitable kind
so long as a spring action is produced thereby. Thus, for instance, Figure 3
shows a zig-zag or angular form which acts in a similar manner to the corrugated
or waved form.
In order to render the spring action as strong as possible, the sheets or laths
are selected as narrow as possible and under some circumstances they are given
an S or Z form. Figure 4 shows an example of the former, and Figure 5 of the
latter. These forms however in order to obtain a suitable pressing on the har
necessitate separate turned up pieces or projections or the like acting against the
pressure of the spring. Thus for instance the material to be removed for forming
the holes to give passage to the bars may be bent back as shown at or the free
edges may be provided with holes and the bars passed through these also as shown
at a in Figure 6.
A further form of construction is shown in Figure 7, the arrangement and action
of which is self evident according to what has been hereinbefore stated.
Figures 8 to 12 show several forms of construction of this in-
vention in which a non-perforated part of the sheet or lath L bears from
the outside against the cross bar S. In the arrangement shown in Figures 10
and 11. the edge of the sheet or lath may either be perforated as the left hand
sides of these figures show and project beyond the crossbar, or, as shown on the
right hand side, may simply bear against the said bar. In Figure 12 two adjacent
laths are shown which have several bearing and clamping points.
The various shapes which are suitable for the object of the present invention in
many other forms, are rolled or pressed out of sheet metal strips or bands.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
The method of fastening sheets, laths, strips or the like metal bodies on cross

page_text: bars or rods for the purpose of forming metallic walls, fences, buildings
and the like which consists in forming the laths or the like (L) of
a bent, corrugated, zig-zag or angular shape and providing them with
holes not exactly in one plane with their edges so as to obtain such a spring
action in a transverse direction that they press on the bars (S), which are passed
transversely through them, at all or some of the points of contact, thus preventing
their lateral displacement along the bars, substantially as hereinbefore set forth.
