Year: 1868

page_text: LETTERS PATENT to James Wallace, of Glasgow, in the County of
Lanark, North Britain, for the Invention of "IMPROVEMENTS IN
DENTAL APPLIANCES."
Sealed the 23rd April 1869, and dated the 27th October 1868.
PROVISIONAL SPECIF
ION left by the said James
at the
Office of the Commissioners of Patents, with his Petition, on the
27th October 1868.
I, JAMES WALLACE, of Glasgow, in the County of Lanark, North
Britain, do hereby declare the nature of the said Invention of "IM-
PROVEMENTS IN DENTAL APPLIANCES," to be as follows, that is to say:-
This Invention relates to the employment of aluminium as a sub-
stitute for other metals and materials employed for dental purposes.
It essentially consists in forming the plates and other parts to which
artificial teeth are connected of aluminium, the different pieces of which
are fastened together by vulcanite or other suitable material.

page_text: Another part of the Invention relates to engraving a design on the
part of the plates next the flesh of the mouth, and by which they are
more securely held in place than when formed plain or smooth.
'
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Wallace in the Great Seal Patent Office
on the 27th April 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WALLACE, of Glasgow, in the County of Lanark, North Britain, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of October, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Wallace, Her special license
that I, the said James Wallace, my executors, administrators, and
assigns, or such others as I, the said James Wallace, my executors,
administrators, or 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
DENTAL APPLIANCES," upon the condition (amongst others) that I, the
said James Wallace, by an instrument in writing under my hand and
seal, 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 immediately after the date of the said Letters
Patent..
NOW KNOW YE, that I, the said James Wallace, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to
say:―
My said Invention relates, firstly, to the employment of aluminium

page_text: as a substitute for other metals or materials used for dental purposes.
It essentially consists in forming the plates and other parts to which
artificial teeth are connected of aluminium, the different pieces of which
are fastened together by vulcanite or other suitable material.
Another part of the Invention relates to engraving a design on the
part of the plates next the flesh of the mouth and by which they are
more securely held in place than when formed plain or smooth.
And in order that my said Invention may be more clearly understood
I have hereunto appended a Sheet of Drawing, the figure on which
represents in prespective plan a set of teeth A, fitted into a layer of
vulcanite B, and fixed to or in combination with the aluminium plate C,
the application of which forms the first part of my said Invention.
The second part of the Invention, viz., the engraving of certain figures
or designs on the plate C for the better attachment of the case to
the flesh of the mouth, is clearly shown in the Drawing, in which the
dark lines a represent one design; but the direction or curvature of
these lines may of course be varied as desired.
Having now described the nature of my said Invention, and the
manner in or under which the same is or may be used or practically
carried into effect, I would observe in conclusion that what I consider
novel and original and therefore claim as the Invention secured to me
by the herein-before in part recited Letters Patent is, the application
of aluminium in lieu of other metals or materials hitherto used for
dental plates, and the formation of a figure or design thereon by
engraving or other means for the better attachment of the same to the
flesh of the mouth.
In witness whereof, I, the said James Wallace, have hereunto set
my hand and scal, this Twenty-third day of April, One thousand
cight hundred and sixty-nine.
