Improvements in and connected with the Method of Manufacturing
Paste.
I WILLIAM HENRY BIRD of 62 Coleshill Street, Birmingham in the County
of Warwick, Butcher (a communication from William Henry Watkins Warbeach
Avenue, Michigan, Detroit, U.S. America) 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 the production of a paste or mucilage suitable
for use by bill-posters; paper-hangers; box-makers merchants; manufacturers and
other persons and suitable for use in a general way as a substitute for the perishable
paste now in general use.
The paste now in general use is so made that after being in use for the purpose
of fastening bills on walls or hoardings, such posted bills are insecure and will peel
off quickly at the first heavy shower of rain, or even with heavy November fog;
in a like manner wall-paper fixed to the walls of dwelling houses by means of
ordinary paste, will and does peel off when the walls become damp, such peeling
results from the partly decomposed putrid state of the paste when used to stick
the bills and wall-paper and partly from the liquefaction of the paste when exposed
to wet or damp.
up
My improved paste sets hard, consequently bill-posting done with the improved
paste remains perfect and secure after heavy rain or fog, in a like manner wall-
paper hung in the rooms of houses by means of my improved paste will not become
loosened from the walls when such walls from any cause become damp.
In making or manufacturing my improved paste I proceed in the following
manner
I provide about 50 pounds of flour, wheat flour by preference, or in lieu of wheat
flour the flour of any other grain or root that will be equivalent to wheat flour as a
basis in the formation of the improved paste; I next provide about 2 & pounds
of alum, also about half an ounce of oil of sassafras, also about one ounce of
boracic acid, also about 200 pounds of water, the flour, water, alum, sassafras-oil
and boracic-acid are mixed into a batter or paste in a suitable receptacle.
In some cases I provide a drum, pan, or tin and securely close such receptacle in
any suitable manner; I next provide and connect to the cooking receptacle one
end of a steam conduit or supply pipe, the other end of the conduit being connected
to a boiler wherein is generated steam, the steam is conducted from the boiler
through the conduit into the metal paste-drum or other receptacle and the contents
of the receptacle is then cooked or boiled by means of the steam and thereby
converted into stick-fast paste.
In course of manufacture for convenience of sale I in some cases use ordinary
wood barrels as paste receptacles, the flour and other ingredients being put
into the barrel and afterwards converted into paste by means of steam in the
manner bereinbefore described in reference to the receptacles and drums made
from metal.
What constitutes the essential novelty in this my invention is the use of
sassafras-oil and boracic-acid as ingredients in the making of paste. The object of
introducing such novel ingredients is to assist in preventing putrefaction and conse-
quent deterioration of the sticking or holding quality of the paste, moreover the
boracic acid has a tendency to dry up the paste where contact is made, that is to
say, after a piece of paper has been stuck on any surface by means of my improved
paste, the air is of course excluded from the joint of contact consequently the thin

page_text: film of paste is quickly dryed up by means of the boracic acid and converted into a
shelly substance thus firmly holding the paper-poster, wall-paper, or other substance
stuck on any surface by means of my improved pastè.
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. The making of stick-fast paste by the combination of the gluten of flour
with the oil of sassafras and also with boracic-acid, as herein described..
2nd. In the manufacture of stick-fast paste, the utilization of closed barrels,
drums and pans containing the ingredients out of which the paste is to be made,
such ingredients being cooked or converted into paste by means of a jet of steam
introduced into the closed barrel, drum or receptacle, as herein described.
Dated this 21st day of November 1893.
