Improvements in and relating to Tiled Boards or Blocks for Floors,
Ceilings, Panels, and the like.
I, GUSTAV JOHAN GRUENDLER, Gentleman, residing at No. 2107, Carr Street,
in the City of St. Louis, State of Missouri, U.S.A., do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement: —
My invention relates to improvements in tiled boards or blocks for floors,
ceilings, panels and the like; and it consists of the novel construction hereinafter
shown, described and claimed.
Figure 1 is a view in perspective of a section of my improved building material,
portions thereof being removed to more clearly illustrate the same. Fig. 2 is
a horizontal sectional view taken approximately on the line 2-2 of Fig. 1.
The base of my improved building material comprises a section of wood 1,
cut into the size and form desired, and provided with the planed surface 2, this
planed surface being coated with an adhesive compound composed of schmiercase
and pulverized burnt lime, and the section of building material is then completed
by locating earthen tile 3 upon said planed surface, which tile will readily adhere
to the wood base by reason of the location of the adhesive compound between said
tile and base.

The material which I denominate schmiercase is also commonly
known as Dutch cheese or cottage cheese. One of its essential ingredients
when fresh is lactic acid. In carrying out my invention it is absolutely essential
that the schmiercase be perfectly fresh, otherwise the lactic acid, an important
element, will be to a great extent dissipated and the compound correspondingly
weakened.
The union of the lactic acid and the lime form calcic lactate, which I have
found makes a cement that is much more durable than if the Dutch
cheese were displaced by ordinary casein or dry cheese.
Furthermore, I have found in practice that the fresh Dutch cheese produces a
cement that is more pliable and much more easily worked than if the Dutch
cheese were displaced by old or dry cheese. Old dry cheese is but slightly
soluble in water, while Dutch cheese is much more soluble in water and can
therefore be much more easily and quickly worked.
When the adhesive compound has become hardened and set, the tile and wood
are permanently joined and neither heat nor moisture will effect the adhesive com-
pound to allow said tile and wood to separate.
My improved building material may be used for flooring, ceiling, wainscoting,
panels, for ornamental work around grates and fire-places and elsewhere.
My improved building material may be manufactured in the workshop and
packed and transported to any distance and owing to the firm bond between the
tile and wood, the same will not become separated, though roughly handled during
transportation.

page_text: A building material of my improved construction may be conveniently used
in a large number of places, and it can be very cheaply and quickly manufactured.
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:
1. The improved building material, consisting of a section of wood and a
section of tile, united by the product known as fresh Dutch cheese containing the
customary proportion of lactic acid in combination with lime, substantially as
herein specified.
2. The herein described adhesive, consisting of the dairy product known as
Dutch cheese containing the customary proportion of lactic acid, in combination
with lime, substantially in the proportion herein specified.
