Improvements in Mucilages, Sizes, and Adhesive Compounds.
I, CHARLES MICHAEL HIGGINS of 168 & 170 Eighth Street Brooklyn, in the
County of Kings and State of New York, in the United States of America,
Manufacturer, do hereby declare the nature of my invention for IMPROVEMENTS IN
MUCILAGES, SIZES AND ADHESIVE COMPOUNDS, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement :-
My improved adhesive compound is formed of water, dextrine and peroxide of
hydrogen, as hereinafter fully set forth.
In forming the compound, I first dissolve the dextrine in the water, either hot
or cold, preferably in hot or boiling water, and when the solution is made to the
desired density. the same is allowed to cool to a temperature of from 60 to 100
degrees Fahrenheit, and the peroxide of hydrogen is then added and gently
stirred in, and the mucilage is then allowed to stand for several days or weeks until
all, or nearly all, precipitable matter has settled, when it will become ready for
bottling or use. The effect of the peroxide of hydrogen on the dextrine solution
is to render it much clearer and lighter, and to retain a much larger portion of the
dextrine in solution than can be retained by a solution in water alone. It is well
known that where a solution of dextrine is made in water alone, that only a portion
of the dextrine will be held in permanent solution, for after the solution cools, or
is allowed to rest for some time, a large portion of the dextrine separates or
I have discovered that when peroxide of
deposits in a dense grayish sediment.
hydrogen is added to the solution a much greater quantity of this dextrine is held
in solution, and only a comparatively small part is deposited and in addition to this
the solution which is thus made more dense and permanent, is also of a much
lighter color and clearer or more transparent in appearance, which are important
advantages. If borax, or boracic acid, is added to the dextrine in making the
solution, the action of the peroxide is much more effective, and almost all the
dextrine is held in a permanent transparent solution, but this addition is covered
by a separate application for Patent executed on the same date with this. My
present application is confined to the compound of dextrine and water and peroxide
of hydrogen, which I find makes a solution much superior to that made by water
and dextrine alone, as already specified, although not equal to that made with the
addition of a boron compound.
The proportions I usually prefer are, say, 7 to 9 pounds of dextrine to the gallon
of water, and to this solution is added to of its volume of peroxide of
hydrogen. The peroxide that I use is the commercial of the strength known as
15 volumes. These proportions may, of course, vary according to the density and
other qualities of the mucilage required, as will be readily understood.
In this compound, the yellow dextrines act better than the white dextrines, but
either may be used, the former being much preferable.
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 :-
1st. An adhesive compound formed of water, dextrine and peroxide of hydrogen,
substantially as set forth.
2nd. An adhesive compound formed by first making a solution of dextrine in

stand and settle, substantially as set forth.
