of Essex, Manufacturer, for the Invention of "IMPROVEMENTS. IN THE
MANUFACTURE OF TRAYS, CASES, AND OTHER SIMILAR ARTICLES AND BOTTLES IN
TRONIE VULCANITE OR OTHER HARD INDIA-RUBBER."
Sealed the 5th August 1862, and dated the 7th February 1862.
PROVISIONAL SPECIFICATION left by the said Hugh Adams Silver at
the Office of the Commissioners of Patents, with his Petition, on
the 7th February 1862.
I, HUGH ADAMS SILVER, of Silvertown, in the County of Essex, Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF TRAYS, CASES, AND OTHER SIMILAR ARTICLES AND
BOTTLES, IN EBONITE, VULCANITE, OR OTHER HARD INDIA-RUBBER," to be
follows:-
as
In manufacturing cases I. form the top and bottom of plates or sheets of
previously prepared ebonite or hard india-rubber, and I unite them at the
sides and ends, all or some of such sides and ends as may be required, by
means of strips or sheets of india-rubber and sulphur, prepared for vulcanizing
in a soft state, unite the soft rubber to the ebonite by india-rubber solvent or
cement, and then subject the whole to the ordinary heat for curing the soft
rubber. For trays the top plate is dispensed with.
In manufacturing bottles I make them in two parts, I form the lower
part in one piece or cup on a mandril, and form the upper part and neck

page_text: in a separate piece, and convert both parts into ebonite, vulcanite, or hard
rubber in the usual manner. I thin off the edges of the two parts, place one
within the other, and apply both inside and outside, or outside only, a strip of
rubber prepared for vulcanizing in the soft state. I next subject the whole
to the curing process, and when the soft rubber has become converted, I turn
down the nrcination curfonos of the joint and the bottle is completed
.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Hugh Adams Silver in the Great Seal Patent Office on
the 6th August 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HUGH
ADAMS SILVER, of Silvertown, in the County of Essex, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of Feby, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Hugh Adams Silver, Her special licence that I, the said Hugh Adams
Silver, my executors, administrators, and assigns, or such others as I, the said
Hugh Adams Silver, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use, exer-
cise, and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF TRAYS, CASES, AND OTHER SIMILAR ARTICLES AND BOTTLES, IN
EBONITE, VULCANITE, OR OTHER HARD INDIA-RUBBER,"upon the condition (amongst
others) that I, the said Hugh Adams Silver, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the 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.
NOW KNOW YE, that I, the said Hugh Adams Silver, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
In manufacturing cases I form the top and bottom of plates
or 'sheets 'of

page_text: previously prepared ebonite or hard india-rubber, and I unite them at the
sides and ends (all or some of such sides and ends as may be required) by
means of strips or sheets of india-rubber and sulphur prepared for vulcanizing
in a soft state, unite the soft rubber to the ebonite by india-rubber solvent
or cement, and then subject the whole to the ordinary heat for curing the
soft rubber. For trays the top plate is dispensed with.
In manufacturing bottles I make them in two parts, I form the lower
part in one piece or cup on a mandril, and form the upper part and neck
in a separate piece, and convert both parts into ebonite, vulcanite, or hard
rubber in the usual manner. I then cut off the edges of the two parts, place
one within the other, and apply both inside and outside, or outside only, a
strip of rubber prepared for vulcanizing in the soft state, using india-rubber
solvent or cement as before; I next subject the whole to the curing pro-
cess, and when the soft rubber has become converted, I turn down the
projecting surfaces at the joint, and the bottle is completed.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim manufacturing
trays, cases, and other similar articles and bottles, in ebonite, vulcanite, or
other hard india-rubber, in manner herein-before described.
In witness whereof, I, the said Hugh Adams Silver, have hereunto set
my hand and seal, this Sixth day of August, One thousand eight hun-
dred and sixty-two.
HUGH A. SILVER. (L.S.)
