page_text: LETTERS PATENT to William Boggett, of Lindsey Houses, Chelsea, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN
PREPARING AND APPLYING SLATE TO USEFUL AND ORNAMENTAL PURPOSES."
Sealed the 19th May 1871, and dated the 14th December 1870.
PROVISIONAL SPECIFICATION left by the said William Boggett at the
Office of the Commissioners of Patents, with his Petition, on the
14th December 1870.
I, WILLIAM BOGGETT, of Lindsey Houses, Chelsea, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN PREPARING AND APPLYING SLATE TO USEFUL AND ORÑAMÉNTAL
PURPOSES," to be as follows :-
In the Provisional Specification of Letters Patent now being applied
for by me, dated the 16th day of September 1870, No. 2494, mechanism
is described for cutting cleaved sheets of slate such as are used for
roofing into curved and other forms.
Now my present Invention has for its object the cutting of slate by
the means above referred to (or by the ordinary means employed for

page_text: cutting slate) into various shapes and figures (in some cases coating them
with colours or other decorative materials and protecting them by means
of enamel, varnish, or glaze), and applying them to the following, among
other purposes, such as forming borders and compartments for flower
beds, for decorating vases, flower pots, boxes, and other vessels of like
character, for decorating the interior or exterior of buildings, ornamenting
cornices, skirtings, shelves, or other articles for which they may be
applicable; also in cutting slate into letters or other shaped figures.
Ordinary roofing slates when coloured and protected by silicic glaze
may also be employed with good effect. In most cases I utilize the
scraps or waste pieces of slate which result from the making of roofing
slates.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Boggett in the Great Seal Patent Office on
the 13th June 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM

thirty-fourth year of Her reign, did, for Herself; Her heirs and suc-
cessors, give and grant unto me, the said William Boggett, Her special
licence that I, the said William Boggett, my executors, administrators,

administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term

vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
PREPARING AND APPLYING SLATE TO USEFUL AND ORNAMENTAL PURPOSES," upon
the condition (amongst others) that I, the said William Boggett, my

page_text: 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 William Boggett, 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 :—
In the Specification of Letters Patent granted to me dated the 16th
day of September 1870, No. 2494, mechanism is described for cutting
cleaved sheets of slate such as are used for roofing into curved and other
forms.
Now my present Invention has for its object the cutting of slate by
the means above referred to or by the ordinary means employed for
cutting slate into various shapes and figures (in some cases coating them
with colours or other decorative materials and protecting them by means
of enamel, varnish, or glaze), and applying them to the following among
other purposes, such as forming borders and compartments for "flower
beds," for decorating vases, flower pots, boxes, and other vessels of like
character, for decorating the interior or exterior of buildings, ornamenting
cornices, skirtings, shelves, or other articles for which they may be
applicable; also in cutting slate into letters or other shaped figures.
Ordinary roofing slates when colored and protected by silicic glaze may
also be employed with good effect. In most cases I utilize the scraps or
waste pieces of slate which result from the making of roofing slates.
Having thus described the nature of my Invention, and the manner
in which the same is carried into practice, what I claim is, the method
of preparing slate and the application thereof to various useful and
ornamental purposes, substantially as herein described.
