PROVISIONAL SPECIFICATION.
Improvements in Treating Broom to Obtain Fibres therefrom for
the Manufacture of Cords, Ropes, and the like, and for other
purposes.
I, FELIX GLOBOTSCHNIG, of Gualdo Tadino, Umbria, in the Province of
Perugia, in the Kingdom of Italy, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
.
My invention relates to the treatment of broom for obtaining fibres therefrom
for the manufacture of cords, ropes, paper pulp and the like.
According to my invention which is the result of many experiments I proceed as
follows:-
The broom tied in small bundles is immersed in a caustic soda solution, prepared
without the aid of heat, the caustic soda being in the proportion of 6 kilos. of soda
to a hundred kilos. of broom (or if the broom has been cut young I may substitute
milk-of-lime for the caustic soda) and boiled for, say, one hour.
Although the above treatment will effect the maceration of the broom it does
not effect the complete removal of the guminy part or resin from the fibres so that
only a rough product is obtained, lacking the flexibility and elasticity which are
especially required in cords, ropes and the like. Furthermore much time is
required to card the broom or to make it fit for the carding. All these incon-
veniences are removed by adding potash to the aforesaid solution whilst tepid, in
the proportion of two kilos. of potash to 650 litres of solution.
Dated this 24th day of June 1895.

When broom treated in the above described manuer is carded a fibre is obtained
which is well adapted for use in the manufacture of cords ropes and the like, and
also of pulp for the manufacture of paper.
.
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 :-
The method of treating broom cousisting in immersing it in a solution of
caustic soda or of milk-of-lime, boiling and adding potash to the solution whilst
tepid, substantially as, and for the purposes, herein before described.
