Complete Specification Accepted, 31st Dec., 1888
I, EDWIN ALBERT TICE, of 77, Macfarlane Road, Shepherd's Bush, in the County
of Middlesex, Dentist, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a dental mirror by which any person can
readily examine his or her own teeth and the said invention consists in the
combination with a small mirror for inserting in the mouth of a larger mirror
adjustably connected to the small mirror and so arranged that by looking in the
large mirror the part of the mouth reflected in the smaller mirror can be clearly
seen.
The mirrors, which may be of any shape but by preference round or oval, are
connected together by a tube or rod, or by two or more tubes sliding telescopically
one within the other, the smaller mirror being hinged or jointed to one end of the tube,
rod or sliding tubes and the larger mirror similarly hinged or jointed to the other
end. The connection of either of the mirrors to the tube or rod is by preference a
ball and socket joint to enable the mirrors to be placed at any required angle
relatively to each other and to remain so placed.
Either plain or magnifying mirrors may be employed and when the latter the said
elescopic connection of the mirrors enables them to be moved nearer together and
farther apart to the proper focus.
When in use the larger mirror not only enables the reflection in the smaller mirror
to be seen but also serves the purpose of a reflector and throws the light into mouth.
I prefer to so arrange the parts that when not in use the mirrors can be folded
flat against the tube, rod or sliding tubes so as to be contained in a case about the
same size as the larger mirror.

page_text: I, EDWIN ALBERT TICE, of 77, Macfarlane Road, Shepherd's Bush, in the County
of Middlesex, 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:-
The object of this invention is to provide a dental-mirror by which any person can
readily examino his or her own teeth and the said invention consists in the combination
with a small mirror for inserting-in-the-mouth of a larger mirror adjustably
connected to the small mirror and so arranged that by looking in the large mirror
the part of the mouth reflected in the smaller mirror can be clearly seen.
The accompanying drawings show what is considered to be the best way for
carrying my invention into effect but it is to be understood that the invention is not
limited to the precise details illustrated. Fig. 1 represents in side elevation Fig. 2
in plan and Fig. 3 in front elevation a dental mirror constructed according to my
invention; Fig. 4 shews the same mirror folded when not in use; Figs. 5 and 6
show parts of the same; Fig. 7 shews how the said dental mirror is used and
Fig. 8 illustrates a modification of my invention.
The same letters of reference indicate the same parts in all the figures.
a is the small mirror for inserting in the mouth and 6 is the larger mirror in which
the reflection from the small mirror is seen. These mirrors are by preference round
but they may be oval or of any other convenient shape. The mirror a has a shank a¹
which is connected by a ball and socket joint c to a tube or rod d, and the larger
mirror 6 has a shank which is connected by a ball and socket joint c¹ to a tube e
which latter fits outside the tube or rod d so that the tubes can slide one within the
other to adjust the mirrors. The ball and socket joints c and c may be of any usual
construction such for instance as that illustrated where a ball is formed at the end
of the mirror shank fitting in recesses between a pair of jaws which can be tightened
by a screw as shown. The tubes d and are shewn round on the drawing but they
may either be of that form or flattened or of any other convenient shape and when
made round I prefer to provide a projecting peg f on the tube d which fits into a
longitudinal slot g in the tubo e to ensure the tubes moving in a straight line. The
outside of the tube e may be roughened as shewn or otherwise formed so as to afford
a firm grip for the user's fingers. The mirror a is by preference made slightly
concave so as to magnify and afford a better view of the teeth.
In using the dental mirror above described the small mirror is inserted by the user
in his or her mouth, a little water having previously been rubbed over the small
mirror to prevent tarnishing by the breath. The user's back should be turned to the
light when, by the joints and adjustable action above described, the larger mirror can
be adjusted so as to show what is reflected by the smaller mirror and enable every
part of the upper and lower teeth to be thoroughly examined by the person using the
mirror.

page_text: When in use the larger mirror not only enables a reflection in the small mirror to
be seen by the user but also serves the purpose of a reflector and throws the light into
the user's mouth.
By sliding the tube or rod d out of the tube e the mirrors as shewn by Figs. 5 and 6
are disconnected and the smaller mirror can be used by one person to examine the
teeth of another person.
The shanks d and b¹ of the mirrors are by preference cranked as shewn so as to
enable the mirrors to fold against the tube as shewn by Fig. 4 to fit into a case of
about the same size as the larger mirror.
If preferred one or more tubes may be provided between the tube or rod d and the
tube e and arraged to slide telescopically one within the other so as to allow of the
mirrors being drawn farther apart.
In the cheaper examples of my invention the sliding adjustment, of the distance
between the two mirrors is dispensed with, a single bar tube or rod being employed to
the ends of which the mirrors are severally jointed as above described.
In the modification illustrated by Fig. 7 the end of the tube to which the larger
mirror is jointed is turned upwardly so as to throw the larger mirror higher up and
more effectually prevent the user's fingers obstructing the view.
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 :-
1st. The combination with a dental mouth mirror of a second mirror adjustably
connected thereto for the purposes and substantially as described.
2nd. The combination and arrangement of parts constituting the improved reflecting
dental mirror hereinbefore described and illustrated by the accompanying drawings.
