Improvements in or connected with Corn Plasters.
I, HENRY DAUBENEY BRANDRETH of 22 Hamilton Square, Birkenhead in the
County of Chester, Patent Medicine Manufacturer, do hereby declare the nature
of this invention to be as follows:-
My invention relates to that kind of corn plaster which has a more or less small
central hole or opening, the plaster being applied to the corn by any convenient
means, for instance, by means of a square or strip of ordinary diachylon plaster.
A well known plaster of this kind, and one manufactured by me, is a small circular
disc, of comparatively small thickness and having its centre stamped out to form
the hole or opening. The office of this kind of plaster, one with a small central
hole or opening, is really to act as a guard or protector in that, when properly
applied, it relieves the tender or thickened part of the corn from the pressure, for
instance, of the boot. Now, according to my present invention, I provide a small
eyelet or head for filling or inserting into the above mentioned small hole or opening,
and this small eyelet or head is composed or made according to any suitable formula
by which the eyelet or head will serve for extracting or exterminating the part of
the corn with which it comes in contact. There are many suitable formulæ, and
more or less strong ones, which are well known to chemists, chiropodists and the
like, my invention does not relate to the composition of these eyelets or heads, but
consists in providing means so that, while the corn is protected, as usual, by means
of a plaster, that plaster can be made to also be of use in aiding the extraction or
extermination of the corn. Any suitable means, as hitherto, for instance the
ordinary diachylon plaster, may still be made use of for keeping the plaster in place.
Dated this 27th day of March 1893.

Improvements in or connected with Corn Plasters.
I, HENRY DAUBENEY BRANDRETH of 22 Hamilton Square, Birkenhead in
the County of Chester, Patent Medicine 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 :-
My invention relates to that kind of corn plaster which has a more or less small
central hole or opening, the plaster being applied to the corn by any convenient means,
for instance, by means of a square or strip of ordinary diachylon plaster.
A well known plaster of this kind, and one manufactured by me, is a small

central hole or opening, is really to act as a guard or protector in that, when
properly applied, it relieves the tender or thickened part of the corn from the

I provide a small eyelet or head for filling or inserting into the above mentioned
small hole or opening, and this small eyelet or head is composed or made according
DO1

page_text: to any suitable formula by which the eyelet or head will serve for extracting or
exterminating the part of the corn with which it comes in contact.
A good formula is as follows
Brown soap ceral
Emp plumbi
Acid salicylic
Ext. cannabis
30 ozs.
10 ozs.
5 ozs.
320 grains
There are many suitable formulæ, and more or less strong ones, which are well
known to chemists, chiropodists and the like, my invention does not relate to the
composition of these eyelets or heads, but consists in providing means so that, while
the corn is protected, as usual, by means of a plaster, that plaster can be made to
also be of use in aiding the extraction or extermination of the corn. Any suitable
means, as hitherto, for instance the ordinary diachylon plaster, may still be made
use of for keeping the plaster in place.
The invention is illustrated in the accompanying drawings,
Figure 1 is a plan of plaster with the parts assembled as in use;
Figure 2, transverse section of same;
Figure 3 small eyelet or head of medicament. This can be of uniform thickness
like a wafer or be hollowed in the centre ;
Figure 4, annular shield;
Figure 5, diachylon or other adhesive plaster.
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. In a corn plaster, the combination of an annular shield, an eyelet wafer
or head of medical composition capable of lying in the hole of the annular shield
and an adhesive sheet covering the same.
2. The eyelet or wafer made to fit a corn shield substantially as described.
