TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWIN
THOMAS TRUMAN, of Old Burlington Street, in tho County of Middlesex,
Dentist in Ordinary to Her Majesty's Household, sond greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by ler Letters
Patent, bearing, date the Eighth day, of January, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of
Her reign, lid, for Herself, Her heirs and successors, give and grant unto
me, the said Edwin Thomas Truman, Her special licence that I, the said
Edwin Thomas Truman, my executors, administrators, and assigns, or such
others as I, the said Edwin Thomas Truman, my executors, administrators,
and 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 In-
vention for "IMPROVEMENTS IN ARTIFICIAL PALATES AND TEETH," upon the
condition (amongst others) that I, the said Edwin Thomas Truman, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, 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 Edwin Thomas Truman, 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 thereof, that is to say :-
-My Invention consists in imbedding or combining wire gauze of any suitablo
metal in or with any mineral substance or substances, which is or are now or
may be employed in the manufacture of artificial palates and teeth. Or, instead
of wire gauze, metal plate perforated so as to form network may be employed,
though not so advantageously. The object of my Invention is to afford as
extended a medium of attachment as may be to resinous substances, such as
gutta percha, or to metals. I employ the means at present adopted for manu-
facturing the teeth or palates, but instead of using pius, slotted plates, or loops
to attach the teeth or palates to other substances I employ wire gauze or

page_text: metallic network for that purpose. I insert the wire gauze into the tooth or
teeth or into the palate in the manner and position best adapted for affording
the most extended medium of attachment to the gutta percha, resinous, or
metallic substances with reference to the situation which the tooth or palate
is intended to occupy in the mouth.
I carry my Invention into effect by pressing suitable parts of the wire gauze
into the substance of which the tooth or palate is formed previous to its being
baked or fired. Thus, in the case of palates, I place thereon a piece of wire
gauze with the edges frayed out, and forming points projecting downwards into
the mineral. The body of the wire gauze remains upon or just above the .
upper part of the mineral substance. After baking, the wire gauze or net-
work upon the top of the mineral presents a surface upon which gutta percha
or other like suitable material may be held or fixed, and this can-be moulded
to the gums, and be made to form an easy and comfortable appliance. In the
case of teeth, the points or frayed edges of the wire gauze are embedded in the
tooth or teeth, and the body of the gauze remains outside on the inner side or
base of the tooth, and affords an extended medium of attachment.
And having now described the nature of my said Invention, and the manner
in which the same is to be performed, I declare that I claim the embedding or
combining of wire gauze or metallic network in any suitable mineral substance
employed in the manufacture of artificial palates and teeth.
In witness whereof, I, the said Edwin Thomas Truman, have hereunto
set my hand and seal, this Eighth day of July, One thousand eight
hundred and fifty-six.
EDWIN THO TRUMAN. (L.S.)
