Year: 1860

page_text: LETTERS PATENT to John Hughes, William Williams, and George Leyshon,
of Brockmoor Works, Brierly Hill, Staffordshire, for the Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF TIN AND TERNE PLATES, AND IN
APPARATUS EMPLOYED THEREIN."
Sealed the 9th November 1860, and dated the 4th September 1860.
PROVISIONAL SPECIFICATION left by the said John Hughes, William
Williams, and George Leyshon, at the Office of the Commissioners of
Patents, with their Petition, on the 4th September 1860.
We, JOHN HUGHES, WILLIAM WILLIAMS, and GEORGE LEYSHON, of Brock-
moor Works, Brierly Hill, Staffordshire, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF TIN AND TERNE PLATES,
AND IN APPARATUS EMPLOYED THEREIN," to be as follows:-
This Invention has for its object improvements in the manufacture of tin and
terne plates, and in apparatus employed therein. In the Specification of a
Patent granted to us, dated the 13th April 1859, (No. 933,) an Invention is
described wherein the plates, after they come from the "washman's pot," are
placed in a rack in a pot containing hot metal, and when the rack is full such
rack is raised slowly and by a steady motion out of the pot. Now, according
to the present improvements, the rack is arranged to remain in the pot, and a

page_text: second rack or apparatus is used to raise the several plates out of the pot and
out from between the spaces of the ordinary rack; the form of this second
rack may be varied, but it is preferred that it should consist of two notched
bars at the lower part, with notches corresponding to the number of spaces
between the ordinary rack; these two bars are affixed to or form part of a
suitable frame by which they are lowered into the pot, so that when the plates
are introduced in succession into the pot between the spaces of the ordinary
rack, the lower edges of the plates will also rest near their ends in the notched
bars or second rack, and when the rack is full of plates, a third notched bar is
caused to be folded across the upper part of the ordinary rack, in such manner
that the notches of the upper bar will receive the upper edges of the plates
between the notches, and thus will the plates be supported about the middle
of their length; this rack is then to be raised, together with the plates, out of
the pot, whilst the ordinary rack remains in the pot. And in order to retain
the heat, a cover is used, which is introduced or folded over the pot and
the moveable rack when full of plates, and such cover is raised up with the
moveable rack.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Hughes, William Williams, and George Leyshon, in
the Great Seal Patent Office on the 4th March 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
HUGHES, WILLIAM WILLIAMS, and GEORGE LEYSHON, of Brockmoor Works,
Brierly Hill, Staffordshire, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of September, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and' grant unto us, the said.
John Hughes, William Williams, and George Leyshon, Her special licence
that we, the said John Hughes, William Williams, and George Leyshon, our
executors, administrators, and assigns, or such others as we, the said. John
Hughes, William Williams, and George Leyshon, our executors, adminis-
trators, 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 TIN AND TERNE PLATES,

page_text: AND IN APPARATUS EMPLOYED THEREIN, upon the condition (amongst others)
that we, the said John Hughes, William Williams, and George Leyshon, our
executors or administrators, by an instrument in writing under our or their
hands and seals, or under the hand and seal of one of us or them, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Hughes, William Williams,-
and George Leyshon, 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 thereof, that
is to say:
This Invention has for its object improvements in the manufacture of tin
and terne plates, and in apparatus employed therein. In the Specification of a
Patent granted to us, dated the 13th April 1859, (No. 933,) an Invention is
described wherein the plates, after they come from the "washman's pot," are
placed in a rack in a pot containing hot metal, and when the rack is full such
rack is raised slowly and by a steady motion out of the pot. Now, according
to the present improvements, the rack is arranged to remain in the pot, and a
second rack or apparatus is used to raise the several plates out of the pot and
out from between the spaces of the ordinary rack; the form of this second
rack may be varied, but it is preferred that it should consist of two notched
bars at the lower part, with notches corresponding to the number of spaces
between the ordinary rack; these two bars are affixed to or form part of a
suitable frame, by which they are lowered into the pot, so that when the plates
are introduced in succession into the pot between the spaces of the ordinary
rack, the lower edges of the plates will also rest near their ends in the notched
bars or second rack, and when the rack is full of plates, a third notched bar is
caused to be folded across the upper part of the ordinary rack in such manner
that the notches of the upper bar will receive the upper edges of the plates
between the notches, and thus will the plates be supported about the middle
of their length; this rack is then to be raised, together with the plates, out of
the pot, whilst the ordinary rack remains in the pot. And in order to retain
the heat, a cover is used, which is introduced into or folded over the pot and
the moveable rack when full of plates, and such cover is raised up with the
moveable rack.
Having thus stated the nature of our said Invention, we will proceed more
fully to describe the manner of performing the same.

page_text: Figure 1 shews a side elevation of a rack ordinarily used, which according
to our Invention remains in the pot; we do not, however, claim the use of a
stationary rack; Figure 2 is a plan thereof; and Figure 3, an end view;
Figure 4 shews a side elevation, Figure 5 an end view, and Figure 6 a plan,
of another rack or apparatus, which is used in combination with the rack
which remains in the pot, and into which the plates are piled one after the
other till all the spaces in the rack are filled. The peculiarity of this Inven-
tion consists in the use of a second rack or apparatus for holding and lifting
the plates out from the pot and out from between the spaces of the stationary
rack. The form or construction of this second or lifting rack or apparatus
may be varied so long as the same is suitable for being lowered into the pot
so as to receive the plates when they are introduced or piled between the
spaces of the stationary rack. a, a, are two notched bars, which are combined
together by two end frames b, b, so as to produce a frame of a size and form
suitable for passing over the rack (shewn at Figures 1, 2, and 3,) which
remains in the pot. The form, however, of the stationary rack and of the
lifting rack may, if desired, be varied so as to admit of the lifting rack passing
into the pot in a position interior of the stationary rack. We, however, prefer
the construction shewn in the Drawing. c, c, are standards, fixed or formed
on the ends of the lifting rack; d, d, are weights, fixed on such uprights by
screws; e, e, are hooks, by which, and by suitable tackle, the lifting rack is
raised, preferring tackle such as is used when only one rack is employed, and
that rack is raised with the plates out of the pot, as was described in the
Specification of the said former Patent; f is a bar, with notches on its under
edge corresponding with the notches in the upper edges of the bars a, a.
bar is capable of being moved out of the way when the plates are being piled
in the racks, and when full this bar is fixed in its place, so that each plate will
rest on the two notched bars a, a, and the upper edge of each plate will be
received into a notch in the upper bar f. The upper bar f is attached by a
hook fat one end, and it is retained down by a sliding bolt f, which slides
over the end of the bar when it is folded down. The lifting rack is then
raised, by which all the plates will be lifted out of the pot and out from
between the spaces of the stationary rack. It is desirable to keep in the heat
of the metal as much as possible, for which purpose we can use a cover, which
we prefer to be attached to the lifting rack, so as to inclose it on all sides, and
by a moveable lid such cover is closed at the top. 9, 9, are the four sides of
the cover, which enclose the rising or lifting rack.
The
One of the sides. .9 is

page_text: arranged to move on a hinge to facilitate the removing of the tin plates from
the rack when they are cold; h is a lid, which is readily put over the top of
the rising rack when it is full of plates and is about to be raised. The lid
should not fit close, but should allow the air to pass both before and when
lifting the cover with the lifting rack. We would state that it is not essential
to employ such cover.
In witness whereof, we, the said John Hughes, William Williams, and
George Leyshon, have hereunto set our hands and seals, this Twenty-
second day of February, in the year of our Lord One thousand eight
hundred and sixty-one.
