Year: 1868

page_text: LETTERS PATENT to William Edward Everitt, of Birmingham, in
the County of Warwick, Tube Manufacturer, for the Invention of
"IMPROVEMENTS IN CASTING COPPER TUBES AND CYLINDERS."
Sealed the 28th October 1868, and dated the 9th May 1868.
PROVISIONAL SPECIFICATION left by the said William Edward
Everitt at the Office of the Commissioners of Patents, with his
Petition, on the 9th May 1868.
I, WILLIAM EDWARD EVERITT, of Birmingham, in the County of
Warwick, Tube Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN CASTING COPPER TUBES AND CYLINDERS," to
be as follows, that is to say:-
The object of this Invention is to remedy the defects arising from the
air holes and cracks usually found in casting copper tubes and cylinders.
I take a mould of iron or other suitable material, the exterior form of
which may be that of any rectangular figure, the interior being that of
an ellipse open at each side; this ellipse is furnished with an internal
sand core, and the side openings are filled with sand wedges or

page_text: pluggings of any other suitable material, the molten copper is poured
into the mould through a lip, and when nearly set the casting and
mould box are removed to a hydraulic or other powerful press, by
the action of which the particles of copper arc forced into intimate
compact, after which the tube or cylinder will have the fins removed
by shearing or otherwise, and it is then ready for drawing or rolling.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Everitt in the Great Seal Patent
Office on the 6th November 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM ]

NOW KNOW YE, that I, the said William Edward Everitt, do hereby

page_text: same is to be performed, to be particularly described and ascertained in
and by the following statement, that is to say :-
The object of this Invention is to remedy the defects arising from the
air holes and cracks usually found in casting copper tubes and cylinders.
I take a mould of iron or other suitable material the exterior form of
which may be that of any rectangular figure, the interior being that of
an ellipse open at each side. This ellipse is furnished with an internal
sand core, and the side openings are filled with sand wedges or
pluggings of any other suitable material, the molten copper is poured
into the mould through a lip, and when nearly set the casting and mould
box are removed to a hydraulic or other powerful press, by the action of
which the particles of copper are forced into intimate compact, after
which the tube or cylinder will have the fins removed by shearing or
otherwise, and it is then ready for drawing or rolling.
Having thus described the nature and object of my said Invention,
and the manner in which the same is to be carried into effect, I claim
the improvements in casting copper tubes and cylinders as herein
described.
In witness whereof, I, the said William Edward Everitt, have
hereunto set my hand and seal, this Fourth day of November,
in the year of our Lord One thousand eight hundred and sixty-
eight.
WILLIAM EDWARD EVERITT. (L.S.)
