I, HENRY JAMES MILLER, of 16, Rue de la Monnaie, Paris, in the Republic of
France, Dentist, do hereby declare the nature of this invention to be as follows:-
Artificial teeth are generally secured to india-rubber or vulcanite
mounts by means of two lugs or "pins" solidly fixed in the teeth.
These lugs do not offer sufficient resistance to prevent the tooth from being
detached from the case or mount or from being broken by a shock or blow.
Moreover, when it is desired to adjust a tooth and the bed or seating of the lugs
pins" are
is approached, the tooth loses its firmness. Moreover the lugs or
always made of platinum and the tooth is thus caused to be somewhat expensive.
In order to obviate these disadvantages. I have devised a new kind of teeth
permitting of their being fixed to the cases or mounts by means of multiple pins
or lugs of any desired metal suitably arranged to permit of their being easily
adjusted whilst retaining all the solidity of the teeth and effecting a considerable
economy in manufacture.
"
To enable me to be readily understood, I have shown in the accompanying
drawing, but by way of example only, the arrangement which forms the subject
of my invention.
In this drawing:
Figure 1 shows the inside view of a canine tooth made according to my said
invention.
Figure 2 is a vertical transverse section thereof on the line 1-2, Figure 1;
Figure 3 is a horizontal section on the line 3—4. Figure 1.
In these figures like letters of reference indicate the same parts.
As shown in the drawing, the tooth is hollowed out and the edges bare
slightly turned inwards.
This tooth is then baked in a furnace or oven brought to a high temperature.
The cavity of the tooth is then filled with a fusible metal at a lower tempera-
ture and, in the mass of metal, I place a suitable number of lugs e arranged
preferably in quincunx, in such a manner that, after cooling, the lugs form a
whole with the metallic mass which is retained in the tooth by the edges b.
The tooth thus prepared, can be adjusted and shaped as required and there
are always a sufficient number of pins or lugs to secure it in the mount.

page_text: It will be understood from the above that if the tooth is subjected to a shock or
blow, the force exerted will not have any detrimental action on the tooth which
cannot either be broken or damaged after the formation of hooks, or be detached
from the case or mount, since the pins or lugs, forming a whole with the mass of
metal retained in the tooth, will not have any detrimental action on the tooth.
It must be understood that, instead of the pins or lugs above mentioned, I can
arrange in the mass of metal any other suitable devices capable of retaining the
tooth or the case or mount in a rigid manner.

or
I, HENRY JAMES MILLER, of 16, Rue de la Monnaie, Paris, in the Republic of
France, Dentist, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
cases
11
or
Artificial teeth are generally secured to india-rubber or vulcanite "
mounts by means of two lugs or pins" solidly fixed in the tooth.
These lugs do not offer sufficient resistance to permit the teeth from being
detached from the case or mount or from being broken by a shock or blow.
Moreover, when the bed or seating of the lugs is approached in adjusting a
tooth, the tooth loses its firmness. Moreover the lugs or "pins" are always made
of platinum and the tooth is thus caused to be somewhat expensive.
In order to obviate these disadvantages, I have devised a new kind of tooth
permitting of its being fixed to the cases or mounts by means of multiple pins or
lugs of any desired metal suitably arranged to permit of its being easily adjusted
whilst retaining all the solidity of the tooth and effecting a considerable economy
in manufacture.
To enable my invention to be readily understood, I have shown in the drawing
filed with my Provisional Specification but by way of example only, the arrange-
ment which forms the subject of my said invention.
In this drawing:
Figure 1 shows the inside view of a canine tooth made according to my said
invention.
Figure 2 is a vertical transverse section thereof on the line 1-2, Figure 1;
Figure 3 is a horizontal section on the line 34. Figure 1.
In these figures like letters of reference indicate the same parts.
As shown in the drawing, the tooth a is hollowed out and the edges bare
slightly turned inwards.
This tooth is then baked in a furnace or oven brought to a high temperature.
The cavity of the teeth is then filled with a fusible metal at a lower tempera-
ture and, in the mass of metal. I place a suitable number of lugs e arranged pre-
ferably in quincunx, in such a manner that, after cooling, the lugs form a whole
with the metallic mass which is retained in the tooth by the edges b.
The tooth thus prepared, can be adjusted and shaped as required and there are
always a sufficient number of pins or lugs to secure it in the mount,

page_text: It will be understood from the above that if the tooth is subjected to a shock
or blow, the force exerted will not have any detrimental action on the tooth
which cannot either be broken or damaged after the formation of hooks on the
pins, or be detached from the case or mount, since the pins or lugs, forming
whole with the mass of metal retained in the tooth, will not have any detrimental
action on the tooth.
a
It must be understood that, instead of the pins or lugs above mentioned, I can
arrange in the mass of metal any other suitable devices capable of retaining the
tooth on the case or mount in a rigid manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
The manufacture of improved artificial teeth formed with a cavity serving to
retain a mass of metal provided with a number of lugs or like devices for fixing
the teeth on cases or mounts of india-rubber, celluloid, or other plastic material,
substantially as hereinbefore described with reference to the drawing, for the
purposes specified.
