Office of the Commissioners of Patents, with bis Petition, on the 13th
December 1867.-A communication from abroad by Daniel Reed, of the
City of New York.
I, EDWARD REED SINTZENICH, of Duke Street, Saint James's, in the
County of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE TREATMENT OF GUTTA PERCHA, INDIA-RUBBER, HONDURAS
GUM, AND THE OTHER ALLIED GUMS FOR THE PRODUCTION OF A PREPARATION OR
PREPARATIONS APPLICABLE AS A VARNISH, CEMENT, PAINT STAIN, WATER AND AIR
PROOF MATERIAL, SOLID OR ELASTIC MATERIAL, AND FOR OTHER PURPOSES," to be as
follows:-
The treatment consists in dissolving such gums in benzine or benzole, or its
chemical equivalents, and by adding alcohol in sufficient quantity, in separating
the purer portions of the gum from the barky, resinous, and other foreigni
substances, the gum rising and collecting in the form of a curd more or less
solid (by the action of the alcohol) which is to be redissolved thoroughly in
benzine or benzole to any consistency for the finer uses, or uses to which it
may be desired to apply it. When the gums thus prepared are to be used for
coarse purposes, such as the treatment of clothes, leather, or woven fabrics, or
substances to render them waterproof, or when used as a cement or coating

page_text: or solid substance the treatment consists in redissolving one part of the curd
formed in the first or finer process in benzine or benzole, and one part in
bisulphuret of carbon or its chemical equivalents, and when both are
thoroughly dissolved the two solutions are mixed together and aro ready
fur use, the gum may conveniently be ground or cut into shreds or small
pieces before being dissolved, coloring matter be added after the preparation
of the solution for forming paints, and evaporated when a solid result is
desired.
When used as a substitute for typo and stereotypo plates or sheets, the
treatment consists in adding to the solution fullers' earth or other similar
material, and in casting or pressing the improved substance or article thus
formed into moulds. For this purpose the substance may be cast or poured
into the moulds as manufactured, or be remelted or dissolved for the purpose,
or be warmed and rendered plastic to allow of being pressed into the moulds.
When used as a substitute for the usual coating applied to insulate telegraphic
wires or conductors, the treatment consists in coating one or more times, as
required, ordinary wires or conductors suitable for telegraphic purposes
with the improved substance or material, or this may be effected by the
hitherto approved process used for covering with gutta percha and indian-
rubber.
When used as a substitute for the materials hitherto used for dental and
surgical purposes, the treatment consists in the evaporating or drying of the
solution either with or without moulds, and either with or without pigments,
fullers' earth, or similar materials to the required degree of hardness for use.
When used as a substitute for collodion as used in chemical, photographical,
and surgical purposes, the treatment consists in the use of the solution of the
proper consistency in the manner in which collodion is now employed. For
photographic printing purposes, and for the production of sun pictures the treat-
ment consists in producing a surface of the solution in the fiuer state on any
convenient material, or using sheets of the same on which may be conveniently
printed the photograph. For waterproof and airproof purposes the solution
may be applied to the object, material, or fabric, or between the two objects,
materials or fabrics as at present. For solid material and as a substitute for
ivory, bone, wood, horn, leather, glass, earthenware, and metals, the treatment
is the same as required for the preparation of type, stereotyped plates, or the
solution with the suitable material is evaporated to the required degreo of
hardness so as to be plastic or otherwise according to the particular purpose to
which it is intended to be used.

page_text: When the solution or substance resulting therefrom is used in conjunction
with leather as a substitute for leather, I use the cuttings of leather ground
up, cut or scraped into shred with the solution in such proportions as shall be
necessary, and by evaporation the required consistency for the purpose intended
is obtained.
