An Improved Dry Flour Paste.
I JOHN H. DAY of the City and County of Albany, State of New York, United
States of America 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:-
The object of my invention is to provide a new article of manufacture consisting
of flour paste in a dry powdered form, which, when diluted in either cold or warm
water, may be used as an adhesive substance for securing paper to a wall, or for
other similar purposes. To accomplish this object I take wheat or rye flour, glue,
and alcohol, mixed usually in the following proportions, to wit: sixteen pounds of
flour, one pound of glue, and one gill of alcohol; but I do not limit myself to these
proportions. These or similar ingredients are diluted with water and cooked in the
manner and to the degree usual in making flour paste. When the paste has been
thus made, 1 evaporate the water from it in any suitable manner, leaving the
residue a dry hard substance, which is ground by any suitable means to a fine powder.
It will be remembered that this powder is rot a mixture of raw ingredients,
which must be subjected to cooking before it can be used.
On the contrary, it
is a substance which is prepared and in condition to be put into immediate use.
All that is necessary to do to make my paste ready for use is to mix it with
water to the required consistence.
By the use of my paste heavy wall-paper can be successfully and satisfactorily
attached to a wall, and will remain smooth and secure thereon.
The advantage of first cooking the paste and then drying it is that it renders
the substance, when again in the liquid form, less "stringy and it dries much
more rapidly. If put on the wall when first made, as is done by the old method,
a stringy mass is formed, especially when put on thick, as is the case when
extremely heavy paper is to be used, and when the paper is brought into contact
with it the paper is caused to puff up, the paste drawing it out of shape, in drying,
and the paste being so thick it takes a long time to dry, and in drying contracts
to such an extent as to loosen the paper, make it uneven, and causes it crumble
off. The powdered paste dries quickly and is more homogeneous, it is not stringy
and has less contractibility, the paper upon which it is used is unruffled, unloosened,
and is held tenaciously to the wall.
The advantages of this new article of manufacture are many.
It emits no
stench, does not draw vermin, is easily stored and transported, can be made ready for
use in a moment's time-in all of these respects different from the liquid paste as now
used.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed I declare that what I
claim is:-
A new article of manufacture resulting from evaporating the moisture from liquid
flour paste composed of flour, glue, and alcohol, and grinding the residue to a fine
powder, substantially as described.
