IMPROVEMENTS IN WIRE DISH AND PLATE COVERS
Year: 1877

page_text: LETTERS PATENT to Henry Brittain, Clerk, and William Albright, Manu-
facturer, both of Birmingham, in the County of Warwick, for the Invention of
"IMPROVEMENTS IN WIRE DISH AND PLATE COVERS."
saled the 29th September 1877, and dated the 6th April 1877.
PROVISIONAL SPECIFICATION left by the said Henry Brittain and William
Albright at the Office of the Commissioners of Patents on the 6th April 1877.
HENRY BRITTAIN, Clerk, and WILLIAM ALBRIGHT, Manufacturer, both of Bir-
mingham, in the County of Warwick. "IMPROVEMENTS IN WIRE DISH AND PLATE
COVERS."
Our Invention consists principally in the use of rivets in place of solder, or solder
and rivets, thereby ensuring a cleaner, stronger, and cheaper fastening of the parts
connected to the wire gauze, but we further strengthen the connection by a cor-
rugation of the gauze and the tin or metal forming the cap plates or centre pieces
and the rim of the cover or one or both of them.
The advantage of the Invention is especially useful, because in soft, or tin-lead
soldering, spirits of salt, more or less diluted or neutralized, is used, and the wire
gauze being of a very light nature is affected, and gradually or quickly becomes
rusted or oxydized, and the cover spoiled.
In manufacturing our wire dish or plate covers, we shape the gauze part in the
usual way, and procure a top and bottom plate, a handle, plate and handle, the
handle plate being fluted or corrugated to fit the handle; the whole are placed in
position, pricked or pierced in two or more places, and rivetted.
In forming the rim the tin or metal is cut in strips of the desired width, bent or
folded, as required, to catch the edge of the gauze; it is then formed to the sweep
or curve of the cover, placed in position and corrugated by wheels in a suitable
frame, so that the gauze becomes corrugated into a groove in the metal; the piece
or pieces of metal or tin forming the rim are then rivetted, and the cover is ready
for blueing, tinning, or painting, as required.

by the said Henry Brittain and William Allbright in the Great Seal Patent
Office on the 5th October 1877.

mingham, in the County of Warwick. "IMPROVEMENTS IN WIRE DISH AND PLATE

Our Invention consists principally in the use of rivets in place of solder or solder
and rivets, thereby ensuring a cleaner, stronger, and cheaper fastening of the parts
connected to the wire gauze, but we further strengthen the connection by a cor-
rugation of the gauze and the tin or metal forming the cap plates or centre pieces:
and the rim of the cover, or one or both of them.
The advantage of the Invention is especially useful, because in soft, or tin-lead
soldering, spirits of salt, more or less diluted or neutralized, is used, and the wire
gauze being of a very light nature is affected, and gradually or quickly becomes
rusted or oxydized, and the cover spoiled.
In manufacturing our wire dish or plate covers, we shape the gauze part in the
usual way, and procure a top and bottom plate, a handle plate, and handle; the
handle plate being fluted or corrugated to fit the handle; the whole are placed in
position, pricked or pierced in two or more places, and rivetted.
In forming the rim, the tin or inetal is cut in strips of the desired width, bent, or i
folded as required, to catch the edge of the gauze; it is then formed to the sweep
or curve of the cover, placed in position, and corrugated by wheels in a suitablo
frame, so that the gauze becomes corrugated into a groove in the metal; the
piece or pieces of metal or tin forming the rim are then rivetted, and the cover is
ready for blueing, tinning, or painting, as required.
Figure 1 of the accompanying Drawings is an elevation of a dish cover as it
appears with our improvements.
A, B, C, & D are the four parts used for the top, A being the handle; B, the
bottom plate; C, the top plate; D, the handle plate; E, represents a plate for the
bottom rim or part of it; F is the same plate folded; this when bent by rolls or
otherwise is slipped on the edge of the dome-shaped gauze, and when not sufficiently
long is accompanied by another folded strip sufficiently long to overlap the ends of
the first part the gauze having been pressed to the bottom of the fold, the tin or
other metal and gauze are wheeled or corrugated together, and the ends (of the tin)
are rivetted; the handle is rivetted by two or more rivets after the plates are put
into position and pricked.
Having now described the nature of our said Invention, and in what manner it
is to be performed, we declare that we do not confine ourselves to the exact form of
the corrugations or the number of rivets, but what we claim in our improvements in
dish and plate covers is manufacturing them without solder, but with rivets, and
the fixing and strengthening of the gauze and rim by corrugation.
In witness whereof, we, the said Henry Brittain and William Albright have
hereunto set our hands and scals, this Fourth day of October, One
thousand eight hundred and seventy-seven.
HENRY BRITTAIN.
