page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, greeting, I,
JOHN NAYLOR, of Hampton, in the County of Middlesex, Millwright.
WHEREAS His present most Excellent Majesty King George the Third,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirtieth day of June, in the twenty-eighth year of His
reigu, did give and grant unto me, the said John Naylor, my executors, ad-
ministrators, and assigns, His special licence, full power, sole privilege and
authority, to make, use; exercise, and vend, during the term of fourteen years
therein mentioned, within that part of Great Britain called England, His
said Majesty's Dominion of Wales, and Town of Berwick-upon-Tweed, and
also in His Majesty's Colonies and Plantations, and Colonies abroad, my
Invention of "AN OVEN FOR BAKING BREAD AND ALL KIND OF VICTUALS, THAT
WILL PERFORM IT'S OFFICE OF BAKING EITHER PLACED UPON OR HUNG OVER A KITCHEN
OR OTHER FIRE LIKE A COMMON POT, OR PLACED ON ONE SIDE OF SUCH FIRE, OR
MAY BE USED SEPARATE AND APART BY ITSELF, AND MAY BE TURNED ROUND WHILE
THE BREAD OR OTHER VICTUALS CONTAINED IN IT FOR BAKING REMAIN IN A FIXED
POSITION, BY WHICH MEANS THAT SIDE OF THE OVEN THAT IS MADE HOT BY BEING
NEXT THE FIRE MAY BE TURNED TO THE TOP OF THE THINGS BAKING, OR TO ANY
OTHER DIRECTION MOST WANTED, AND WHICH I CALLED A ROTATIVE OVEN;" in which
said Letters Patent is contained a provisoe or condition, requiring and
obliging me, the said John Naylor, to cause a particular description, by
an instrument in writing under my hand and seal, of the nature of the said

page_text: Invention, and in what manner the same is to be performed, to be inrolled in
His Majesty's High Court of Chancery within one calendar month next and
immediately after the date of the said Letters Patent, as in and by the said
recited Letters Patent, relation being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that I, the said John Naylor, in compliance with and
performance of the aforesaid provisoe or condition, do hereby declare that
the following is a particular description of the nature of my said Invention,
and in what manner the same is to be performed, that is to say :-
The vessel or oven may be made of various forms; it's difference from all
other ovens arises entirely from it's turning round while the bread or victuals
contained in it remain in a fixed position. To produce this movement the
front or mouth of the vessel or oven will be made round, as it there rests
upon a frame. The back part of the vessel or oven is supported by a bolt,
which goes through the centre of the vessel or oven into a frame behind,
where it is made fast. The frames, as well as the vessels or ovens, will be
made of different forms and sizes so as to suit different occasions, but in every
form and size the principle of action or rotative motion is exactly the same;
and this principle or motion may be produced either occasionally by hand or
regularly by a common kitchen jack upon that end of the bolt which supports
the back of the vessel or oven; within the same will be fixed a frame, to
which shelves will be placed for holding what may be put into the oven for
baking, and such shelves may be fixed or moveable, and will be formed
And I, the said John
differently according to the size and shape of the oven.
Naylor, do hereby aver and declare that the above is a particular description
of the nature of my said Invention, and in what manner the same is to be
performed.
In witness whereof, I, the said John Naylor, have hereunto set my hand
and seal, the Twenty-ninth day of July, in the twenty-eighth year of the
reign of His said Majesty King George the Third, and in the year o
our Lord One thousand seven hundred and eighty-eight.

said, and every article, matter, and thing therein contained and specified,
and that the same was duly stampt according to the tenor of the Statute in
such case made and provided.
