1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to provide a medicated and curative court plaster in
an improved form by means of which the fabric will fit closely over and upon
irregularities of surface, while ventilation of and access to the part covered is secured
without removal of the plaster during the healing process.
My improvement consists in a court plaster finely perforated throughout, so as to be
flexible rather than stiff when applied to the skin, and having a curative medicament
as or combined with the adhesive coating on one of its surfaces. The peculiar value
of my court-plaster is due both to the healing qualities of the adhesive coating and to
the vents afforded by the multiplicity of fine perforations through which air and any
external applications or lotions may enter to act upon all parts of the sore, and pus or
like matter may escape therefrom, so that the healing is not retarded by the presence
of foreign matter which, with the ordinary court-plaster, is prevented from escaping.
In addition to this far better adhesion is secured, because the perforations allow the
air to escape from heneath the plaster and make the sheet more limp and flexible when
wetted, causing it to fit on and adhere to all inequalities of the surface and to yield
freely wherever the perforations occur. The fibres of the tissue or fabric and even
the gum of the coating absorb lotions or other external applications and hold them in
intimate contact with the sore at all points.
The adhesive coating has the healing qualities of bacteriacides and antiseptics, and
all the ingredients are entirely unobjectionable, the adhesion being due to pure
isinglass. Thus the most eminent physicians and surgeons will readily recommend so
indispensable an article.
In my improved plaster, the perforations occupy about one fourth of the entire
surface over which they are equally distributed.
I make this improved perforated plaster with a body of fine linen or like textile
fabric, or of kid or other skin, or such texture as from its yielding qualities is adapted
to my purpose. I am accustomed to apply the coating smoothly upon one side of the
continuous sheet and when it is dry to perforate the sheet uniformly by suitable
machinery, after which it is separated into sheets of convenient size for sale, or it may
be put up in rolls.

page_text: I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 this invention is to provide a medicated and curative court plaster in
an improved form by means of which the fabric will fit closely over and upon
irregularities of surface, while ventilation of and access to the part covered is secured
without removal of the plaster during the healing process.
My improvement consists in a court plaster finely perforated throughout, so as to
be flexible rather than stiff when applied to the skin, and having a curative
medicament as or combined with the adhesive coating on one of its surfaces. The
peculiar value of my court-plaster is due both to the healing qualities of the
adhesive coating and to the vents afforded by the multiplicity of fine perforations
through which air and any external applications or lotions may enter to act upon
all parts of the sore, and pus or like matter may escape therefrom, so that the
healing is not retarded the presence of foreign matter which, with the ordinary
court-plaster, is prevented from escaping. In addition to this far better adhesion
is secured, because the perforations allow the air to escape from beneath the plaster
and make the sheet more limp and flexible when wetted, causing it to fit on and
adhere to all inequalities of the surface and to yield freely wherever the perforations
occur. The fibres of the tissue or fabric and even the gum of the coating absorb
lotions or other external applications and hold them in intimate contact with the
sore at all points.
The formula for the adhesive coating is as follows:-
To one gallon of borax water (from refined borax) is added one pound of refined
sulphur, one half pint liquid extract of wormwood, and one or two ounces of glycerine.
Half a pound of refined fullers earth, is then dissolved in water and the solution
strained off and added. This mixture is then compounded with five pounds of
refined fish glue dissolved and brought to a boiling point. The whole composition
is reduced to a consistency suitable for spreading.
The adhesive coating has the healing qualities of bacteriacides and antiseptics,
and all the ingredients are entirely unobjectionable, the adhesion being due to pure
isinglass. Thus the most eminent physicians and surgeons will readily recommend
so indispensable an article.
In my improved plaster, the perforations occupy about one fourth of the entire
surface over which they are equally distributed.
I make this improved perforated plaster with a body of fine linen or like textile
fabric, or of kid or other skin, or such texture as from its yielding qualities is
adapted to my purpose. I am accustomed to apply the coating smoothly upon one
side of the continuous sheet and when it is dry to perforate the sheet uniformly
by suitable machinery, after which it is separated into sheets of convenient size for
sale, or it may be put up in rolls.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is :-
1. Perforated court-plaster having an adhesive surface and thin, flexible body,
substantially as set forth.
