A Material suitable for Use in Building and the like, and Means
for Manufacturing the same.
I OTTO SCHWARZ, Architect of 48 Augustenstrasse, Munich in the Empire of
Germany, do hereby declare the nature of this invention to be as follows
According to this invention wood-wool in connection with suitable kinds of
mortar is used for the manufacture of an insulating building material, capable of
being easily worked with the sand and of holding securely nails and hooks. It is
thus suitable for making planks, plinths and blocks of any shape and cross-section
for the building of partition walls, linings, ceilings and so on. In accordance
with the cross sections required, different forms and mechanical arrangements are
needed to render a cheap manufacture of this building material possible.
The wood-wool may either be employed without any preparation or it may be
impregnated beforehand with an antiseptic substance, in order to render the
building material made of it durable in every respect. Such substances for
impregnation are for instance ferrous chloride, sublimate, iron and copper sulphate
and others. As a suitable binding medium or mortar, gypsum, plaster or any kind
of cement may be used. The mortar may receive additions of marble dust or
other fit mineral, lime-dust, coal ashes or the like. The wood-wool is employed
either loose or spun.
It is either worked together first most intimately with the
mortar and then brought into the form, to be described later on, pressed and dried ;
or the mortar and the wood-wool are brought into the form separately in layers or
strata so that by subsequent pressure a solid and intimate union of these ingredients
is obtained. After the form has been opened the mortar having set, the block or
the like containing the wood-wool is taken out of the form and finally dried. The
consistency in which the mortar is applied de; ends on its composition. It can be
employed as a thin fluid or a paste. If the wood-wool is brought into the form
separately from the mortar, it will suit the purpose if it is spun beforehand into
ropes of suitable length.
The form-press is composed of a frame with angular supporting rails affixed in it
upon which the bottom rests. The latter is connected with the frame by means of
lugs and pins at one end, and is thus hinged and carries at said hinged edge one
side wall of the frame. With the frame the cover is connected movably by means
of hinge joints at the other end of the form. Beyond this hinge joint a support
protects the cover from falling back entirely when it is lifted up.
The form is thus composed essentially of a solid frame with which an angular
bottom and a cover are hinged. The opening and closing of the cover may be
done either by hand or by mechanical means; for moving the bottom an angle
lever connected movably with the frame carries rolls abutting against the underside
of the bottom. With the bottom an eccentric lever is connected by means of links
in order to afford means for pressing down the cover. The cover is constructed in
such a way as to pass into the frame, by which means pressure may be given to the
contents of the form; the side parts of the form can be provided with any suitable
profile in which case, for taking out the block the gudgeons of the bottom are
capable of being horizontally moved in slits of the frame.
The method of operation is as follows:-
On the bottom of the form-press mortar is poured consisting of gypsum or a

stone etc. The wood-wool is then put in and the form is filled with mortar up to
the margin, the cover is shut down and pressed down by means of the eccentric
lever.
When the block has set sufficiently the eccentric levers are loosened, the cover
is opened and the bottom, together with the block is lifted up by means of the
angle lever. Besides planks and plinths with smooth flats or faces above described,
blocks corrugated on one or both sides or provided with suitable profile may be
made. The corrugations can be round, angular or of any other profile. The
means above described for manufacturing smooth planks or blocks can be used
for manufacturing corrugated planks and the like. For this purpose instead of
the smooth or plane bottom and cover plates, others of corresponding form are
employed.

A Material suitable for Use in Building and the like, and Means
for Manufacturing the same:
I, OTTO SCHWARZ, of 48 Augustenstrasse, Munich, in the Empire of Germany,
Architect 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 :-
According to this invention wood-wool in connection with suitable kinds of
mortar is used for the manufacture of an insulating building material, capable of
being easily worked with the saw and of holding securely nails and hooks. It is
thus suitable for making planks, plinths, and blocks of any shape and cross section
for the building of partition walls, linings, ceilings, and so on. In accordance with
the cross sections required, different forms and mechanical arrangements are needed
to render a cheap manufacture of this building material possible.
The wood wool may either be employed without any preparation or it may be
impregnated beforehand with an antiseptic substance in order to render the
building material, made of it durable in every respect. Such substances for
impregnation are for instance, chloride of iron sublimate, iron and copper sulphate,
and others. As a suitable binding medium or mortar, gypsum, sand, plaster or
any kind of cement may be used. The mortar may receive additions of marble
dust or other fit mineral lime-dust, coal ashes slack or coal dust or the like. The
wood wool is employed either loose or twisted or bundled together. It is either
worked together, first, most intimately with the mortar and then brought into the
form, to he described later on, pressed and dried; or the mortar and the wood wool
are brought into the form separately in layers or strata so that by subsequent
pressure a solid and intimate union of these ingredients is obtained. After the
form has been opened the mortar having set, the block or the like containing the
wood wool is taken out of the form and finally dried. The consistency in which
the mortar is applied depends on its composition. It can be employed as a thin
fluid or a paste. If the wood wool is brought into the form separately from the
mortar, it will suit the purpose if it is twisted or bundled together beforehand into
ropes of suitable length.
In the annexed drawings Fig. 1 shows the cross section of a form-press serving
usually for the manufacture of smooth planks.
The form press is composed of a frame a with angular supporting rails k affixed
in it upon which the bottom d rests.

page_text: The latter is connected with the frame a by means of the lugs and pins é at one
end and is thus hinged and carries at said hinged edge a wall completing the frame.
With the frame a the cover b is connected moveably by means of hinge joints
at the other end of the form.
Beyond this hinge joint a support i protects the cover 6 from falling back entirely
when it is lifted up.
The form is thus composed essentially of a solid frame a with which an angular
bottom d and a cover bare hinged.
The opening and closing of the cover may be done either by hand or by
mechanical means. For moving the bottom d an angle lever f connected movably
with the frame a carries rolls abutting against the under side of the bottom.
With the bottom an eccentric lever his connected by means of links g in order to
afford means for pressing down the cover.
The cover 6 is constructed in such a way as to pass into the frame, by which
means pressure may be given to the contents of the form.
If instead of flat plates, plates with corrugations, undulations etc. of any section
are to be made, the bottom 6 is shaped accordingly. The side parts of the form
can be provided with any suitable profile as at y in which case, for taking out the
block the gudgeonse of the bottom d are capable of being horizontally moved in
slits of the frame by means of lever v turning on pin x and having a groove or
fork w embracing the gudgeon e.

In order to hold fast the lever when the bottom is moved forwards, there is
provided an arm which is fixed on the frame and which can be brought in
co-operation with the lever v, in order to keep the same in the position shown in
Fig. 3.
In order to open the press, the arm is moved back; the lever vis
brought from the position in Fig. 3 to that of Fig. 4, whereby the bottom is pulled
forward and the produced block can be taken out from the form without damaging
the profile y. Instead of providing the lever f with a roll r (Figs. 1 and 2), the
same may also be bent as at r¹.
The method of operation is as follows:-
On the bottom d' of the form press, mortar is poured consisting of gypsum or a
mixture of about 1 part lime, 1 part sand, and 2 parts gypsum, or Roman cement,
or Portland cement, with or without addition of sand or coal ash powder, tufa,
limestone etc.
The wood wool is then put in and the form is filled

When the block has set sufficiently the eccentric levers are loosened, the cover
is opened, and the bottom together with block is lifted up by means of the angle
levers f.
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. A method of manufacturing a building material in the form of planks, blocks,
or the like, bricks etc., in which wood wool prepared or not with antiseptic
substances, loose or twisted or bundled together is mixed together with a mortar of
gypsum, lime sand cement, or so on and brought into suitable forms and dried.
2. The method of manufacturing building material of wood wool consisting in
pouring in and pressing fluid materials such as gypsum, lime sand, coal ashes or dust
cement, &c. and the like and wood wool, into a form press of suitable form in which
operation the wood wool is either to be mixed intimately with the binding medium
before being brought into the form, or the wood wool eventually twisted or bundled
together in the form of ropes, and the binding medium are brought in separately.
3. A form press consisting of a frame a, the one side of which forms one piece
with the bottom d lying on the supports k, which botter. can be lifted out of the
form by means of the lever f and the cover of which can be pressed firmly on the

page_text: material by means of an eccentric lever h movably connected with the flat or undu-
latory bottom the bottom or cover being formed corresponding to the profile of the
block which is to be manufactured.
4. In the forming press described in Claim 3 for plates profiled on the sides an
endwise movable bottom adapted to be kept in an advanced position by means of a
lever which leans against the lever v.
