Improvement in Silk and other Hats.
I, ARNOLD ADOLF RICHARD BÖHME of Potsdamer Strasse, Berlin, in the
German Empire, Hat Manufacturer, 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 :-
In silk hats and similar stiff covered hats the very great defect of allowing
grease to percolate in the region of their seat on the head has hitherto not been
effectually remedied. Attempts have been made to do so by interposing between
the leather lining and hat crown insertions of waterproof materials. Although by
such insertions the percolation of grease was retarded, it was not entirely prevented,
because a merely waterproof loose insertion could not prevent greasy particles
from penetrating to the outside and principally, because it was not worked into the
hat in a manner suitable to the purpose. If a hat is to be protected against.
percolation of grease, the joint between the hat brim and crown side must be made
tight in such a manner that a gradual penetration of grease at this place is prevented
and my invention consists in effecting this by so arranging the insertion that such
penetration is rendered impossible and in the method of or process for attaching
said insertion.
In carrying out my invention I form the foundation of the crown and brim in
the usual way by taking for making the brim a piece of barchent or equivalent
material of suitable size, covering it with powdered shellac and ironing the powder
in with a moderately hot iron. This imparts the requisite stiffness to the brim.
In the ordinary way of manufacturing hitherto used the brim is then covered on
both sides with calico or equivalent fabric pasted on, the inner edge of the brim
joined to the crown and after covering and lining the saine and placing an insertion
between the leather lining and side the hat is finished for sale. This insertion.
however only protects to some extent the side of the crown but does not protect
the brim against the action of perspiration and grease.
I attain this object, as shewn on the drawing appended hereunto in several
sectional views, by extending the grease proof insertion from the brim. to the
crown side so that the joint of the hat brim and crown is perfectly protected against.
the percolation of perspiration or grease. The foundation a of the brim A.
consisting of barchent or usual materials is connected to the grease proof inser-
tion 6 by placing said insertion upon the underside of the foundation of the brim
and covering it with a sheet c of linen or equivalent material, and connecting the
three layers a b and c by hot ironing. In order to protect the insertion 6 against
the effect of the hot iron, a thin layer of indiarubber d may be placed between the
insertion 6 and the layer of linen c. These several layers are not cut out as large
as the brim in the centre, so that when connected to the brim they project beyond
the inside edge of the brim as indicated by dotted lines on Fig. 3, and after the
crown B has been put on, are firmly connected to it in the same manner as to the
brim, so that the joint e of the parts A B is covered on the inside by the grease
proof insertion b, (respectively b and d) and the linen c. The insertion bord is.
carried to such a height in the crown B, that the grease transferred to the interior
of the hat from the skin or hair at the place of contact cannot pass above said.
insertion.
The hat body prepared in the manner described with a grease proof insertion
covering the joint of crown and brim, is then covered with silk plush, cashmere,
felt or other covering and finished in the usual manner.

page_text: 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 :
1. The process of manufacturing grease proof silk and similar covered hats by
cementing a layer bord of proofing material covering the joint between the
brim A. and crown B and extending partly over the lower side of the brim and
partly into the inside of the crown first by hot ironing to the body a of the brim A
and after the crown has been joined to the brim also to the crown side, and then
finishing the hat in the usual way by covering it with silk plush, cashmere or other
materials:
2. In hats the arrangement and use of a layer (bor bd) of grease proof materials
covering the joint of the brim and crown and extending over the underside of the
brim and into the inside of the crown to such a height that a percolation of grease
or perspiration is prevented.
