County of Warwick, Manufacturer, for the Invention of "IMPROVEMENTS

Sealed the 1st March 1864, and dated the 5th September 1863.
PROVISIONAL SPECIFICATION left by the said Charles Henry Adames
at the Office of the Commissioners of Patents, with his Petition, on the
5th September 1863.
I, CHARLES HENRY ADAMES, of Birmingham, in the County of Warwick,
Manufacturer, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN THE MANUFACTURE OF LIDS OR COVERS FOR CERTAIN ARTICLES OF:
HOLLOW-WARE," to be as follows, that is to say :-
I take a disc or sheet of iron, and stamp it into a domical form, and
then to raise the shoulder, and contract the rim or ring, I employ a pair
of rollers, one flanged the other grooved, and cause them to revolve in a
planetary circuit round the internal periphery of the dome at such a distance.
from the edge as will allow a sufficient depth for the rim, the dome itself.
also revolving.
For other forms of covers than circular ones a different motion of the
chock holding the dome will of course be necessary. In attaching the.
knobs or handles to these covers, I pierce through the knob and pass ·
a

page_text: rivet piece through the crown of the dome and through the aperture, tho
head of the rivet being on the under side of the dome and upon the
upper side of the knob; I rivet down the shank of the rivet piece into a
countersinking formed upon the head of the knob. The parts are all
tinned before being put together, and again after they are combined; the
effect of this is to unite them all firmly together. I can also produce
the same form of ring and shoulder in metals admitting of such treatment
by the common process of spinning after the dome shape has been pro-
duced by the stamp, the knobs being also attached in similar manner, but
dispensing with the tinning process for articles in copper or other metals not
requiring it.
The advantages of employing these processes of manufacture are that the
dome, the shoulder, and the rim of the cover are all in one piece without joint
or solder, and the knob is securely united.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Henry Adames in the Great Seal Patent Office on
the 4th March 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
HENRY ADAMES, of Birmingham, in the County of Warwick, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of September, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles Henry Adames, Her special license that I, the said Charles
Henry Adames, my executors, administrators, and assigns, or such other's
as I, the said Charles Henry Adames, 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, exercise, 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 LIDS OR COVERS FOR CERTAIN ARTICLES
OF HOLLOW-WARE," upon the condition (amongst others) that I, the said Charles
Henry Adames, by an instrument in writing under my hand and seal,
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

page_text: 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 Charles Henry Adames, 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, reference being had to the Drawings hereunto annexed
and to the letters and figures marked thereon, that is to say :-
My Invention consists, firstly, in an improved mode of raising the shoulder,
and contracting the rim in covers for hollow-ware articles. I take a disc or
sheet of iron, and stamp it into a domical form, and then to raise the shoulder
and contract the rim or ring, I employ a pair of rollers, one flanged the other
grooved, and I cause them to revolve one round the external the other round
the internal periphery of the dome, at such a distance from the edge as-will
allow a sufficient depth for the rim, the dome itself also revolving.
.
Secondly, my Invention consists of improvements in attaching the knobs.
or handles this description of cover, which is thus carried out :-I pierce
through the knob and pass a rivet piece through the crown of the dome.
and through the hole in the knob, the head of the rivet being on the
underside or inside of the dome. Upon the upper side of. the knob- I
form a countersinking; into which I rivet down the slank of the rivet piece.
The parts are all tinned before being put together, and again after they have.
been combined, the effect of which is to unite them all very, securely
together.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a section of the domo which is, to form a cover in
the state in which it leaves the stamp; Figure 2, a section of a cover com-
plete; Figure. 3, a side elevation of the rolling machine I prefer to employ;"
and Figure 4, a top plan view of the same machine.
I will now proceed to describe the process of manufacture by the aid of
these Drawings, merely premising that the machine herein shewn is but the
well-known' apparatus termed in the trade a "jenny," altered to adapt it to
my present purpose; it will therefore be unnecessary that I should enter very,
fully into its general working details, as they will be familiar to any one
accustomed to the trade, and I will therefore confine my description to those
parts which I have added or altered for the purpose of this Invention. I
take the shell or dome stamped out as seen in Figure 1, and place it upon
the lower roll (a), the upper roll (6) being raised by means of the spring to
admit the dome between the rolls. I then screw down the upper roll by

page_text: meaus of the wheel and screw c, and by an inward movement of the lever
rod (d), I bring the cushion (e) up to the crown of the dome, and thus keep
it in position, the same movement of the rod (d) throwing the driving band
on to the fast or driving pulley (f), and thus putting the machine in motion.
Both rolls revolving, and the dome also revolving with the lower roll, the
shoulder and rim are formed. The reverse movement of the lever rod (d)
throws the machine out of gear, removes the cushion (e) from contact with the
cover, and by raising the top roll the cover can be removed, and is ready to
receive the knob or handle. The manner of attaching this knob is seen in
Figure 2, in which (9) is the knob and (h) the rivet piece, the head of which
is on the under side of the dome and the other end rivetted down in the
countersinking on the head of the knob.
I have stated in my Provisional description that for covers of other forms
than circular a different motion of the chock holding the dome would be
requisite. I find in practice that I can produce various other forms by the
same apparatus without alteration. I have also alluded to a mode of forming
the shoulder and rim by the operation of "spinning," a process which I have
since discovered to have been previously in use, and I therefore make no
claim to such process.
Having thus described the nature of my said Invention, and the manner
in which the same is to be performed, I do not claim the apparatus or
machinery herein described except in so far as regards the modifications
thereof or additions thereto requisite for the purposes of my Invention, but
that which I claim is the improvements in the manufacture of lids or covers
for certain articles of hollow-ware by rolling the shoulder or rim, and by
securing the knobs or handles in manner substantially as herein more fully set
forth and specified.
In witness whereof, I, the said Charles Henry Adames, have hereunto
set my hand and seal, this Third day of March, in the year of our
Lord One thousand eight hundred and sixty-four.
CHARLES HENRY ADAMES.
