Fields, in the County of Middlesex, Gentleman, for the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF CAPSULES FOR ENCLOSING
MEDICAMENTS AND OTHER SUBSTANCES, AND IN THE APPARATUS EMPLOYED

ealed the 13th July 1875, and dated the 1st March 1875.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson
at the Office of the Commissioners of Patents, with his Petition, on
the 1st March 1875.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County
of Middlesex, Gentleman, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF CAPSULES FOR ENCLOSING
MEDICAMENTS AND OTHER SUBSTANCES, AND IN THE APPARATUS EMPLOYED THEREIN,"
a communication to me from abroad by Rudolf Taetz, of Moscow, in the
Empire of Russia, Chemist, to be as follows:-

page_text: be introduced into the stomach without having any action upon the
organs of taste, and it consists in forming the capsules of a peculiar
composition of substances, and of an improved mode of and apparatus
for producing such capsules.
The before-mentioned substances are melted in a water bath and
carefully stirred in order to obtain a liquid of the consistence of syrup,
and then clarified.
The moulds may be composed of any suitable material adapted to the
liquid they are subsequently intended to receive.
In manufacturing the capsules the operator lays hold of the mould
by its handle and dips it into the semi-liquid mass, care been taken by a
quick and dexterous turning of the mould to spread the last drop
equally over the whole surface in such a manner as to cause the part
where the handle is situate to be covered to a somewhat greater thickness
than the other portions.
In order to effect the removal of the capsules from the moulds (which
may take place from 1 to 1 hour after the operation of dipping) the
capsule is cut round with a cutting tool close to the handle, the portion
of the composition which may remain on the handle is cleaned away,
and the capsule now prepared is drawn down from the mould by a quick
but uniform rolling, care being taken that the capsule be not completely
turned down.
The closing of the filled up capsules is effected with the same com-
position by the employment for this purpose of a round horn in the
form of a ring made, say, for example, of silver wire corresponding with
the aperture to be closed. The wired horn is dipped into the semi-
liquid, its opening being covered therewith, and then placed upon the
capsule, which is in this manner perfectly closed up, care being taken
to maintain the semi-liquid mass at a suitable warm temperature.

filed by the said John Henry Johnson in the Great Seal Patent
Office on the 28th August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN

from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel

MANUFACTURE OF CAPSULES FOR ENCLOSING MEDICAMENTS AND OTHER SUBSTANCES,
IN THE APPARATUS EMPLOYED THEREIN,' a communication to me
from abroad by Rudolf Taetz, of Moscow, in the Empire of Russia,
Chemist, upon the condition (amongst others) that I, the said John
Henry Johnson, my executors or administrators, by an instrument in
writing under my hand and seal, should particularly describe and

same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
AND
"
NOW KNOW YE, that I, the said John Henry Johnson, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :-
The said Invention relates to elastic or flexible capsules intended
more particularly for containing medicaments, so as to enable the same
to be introduced into the stomach without having any action upon the
organs of taste, and it consists in forming the capsules of a peculiar

page_text: perfectly closed up, the horn or socket being subsequently removed
ready for closing a fresh capsule. Care is to be taken to maintain the
semi-liquid mass at a suitable warm temperature.
Having now described and particularly ascertained the nature of the
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is,-
First. The employment for the production of capsules of the compo-
sition herein-before described.
Second. The manufacture of capsules substantially in the manner and
by the means herein-before described.
In witness.whereof, I, the said John Henry Johnson, have to this
my Specification set my hand and seal, the Twenty-eighth day
