PROVISIONAL SPECIFICATION.
Improvements in Marking or Branding Articles of Food.
I, ALFRED ELLIS HARRIS, of, 64, Finsbury Pavement, in the County of
London, Dentist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the marking or branding of perishable or preserved
articles of food, such as sausages, smoked tongues, fish, and the like.
Many attempts have been made to mark or brand such articles in a permanent
and indelible manner but hitherto such attempts have not been attended with
success, such marking or branding which may have been applied to the articles
having become obliterated or partly obliterated by the treatment to which the
articles are subjected during the curing process or in transport and storage.
According to my invention the articles or the skins containing them can be
marked or branded either before or after they have been cured.
For this purpose I first brush over the surface or part to be marked or
branded with a suitable alkali such as solution of potash (British Pharmacopoeia)
so as to remove the greasy or fatty matter thereon. I then by means of nitrate
of silver mark or brand the goods with such letters, marks or otherwise as
required and on being exposed a suitable time to light the mark or brand will
develop.
I may use the nitrate of silver in the form of a pencil with water or I may
use a solution of nitrate of silver adding thereto any suitable mucilage or the
like to obtain a consistency such that stamps or the like may be coated with
the solution and the goods marked by means of such stamps; or I may use
stencil plates and brushes.
