-2 Claims._ (oi. 128—359)- '
The present invention relates to a novel teeth
which‘ will cause a more eifective massaging of
ing device and more in particular to such a con
the gums. These raised portions or protubere
struction so designed and arranged as to properly
reach the areas of the gums which require stim
ulation and aid in the eruption of the'teeth.
In the cutting of teeth by’ an infant there is
normally little dii?culty with the cutting of the
ances may be of any shape or design effective for
' the purpose, although it is to be understood that
the device may be made smooth, if desired.
Further objects are to provide a construction
of maximum simplicity, emciency, economy and
anterior teeth which comprise the six upper and. ease of assembly and operation, and such further
six lower teeth. These are the ?rst to arrive objects, advantages and capabilities as will later

_ cut or break through the gums.
However, in
the cutting or eruption of the posterior teeth or
molars, since these are Y formed with a broad
erupting surface having spaced cusps, they most
generally cause considerable pain and soreness
in the gums ‘and require stimulation and aid in
their eruption.
_
'
The present invention has for an object to aid
thereby.

The invention further resides in the construc
tion, combination and arrangement of parts il
lustrated in the accompanying drawing, and
while I have shown therein a preferred e'mbodi- 15
ment, it is to be understood that the same is
~ susceptible of modi?cation and change, and com
prehends other details, arrangements of parts,
in the stimulation of the gums and in the erup
features and constructions without departing
tion of the posterior teeth. The novel device is from the spirit of the invention.

.
Another distinct advantage of the present in
vention is that when thedevice is inserted in the
mouth of the infant, there is nothing that inter-_
,feres with the tongue or which would be of a
sufiicient length to touch the soft palate. Thus
it will be noted that no portion of the device will
overlie the tongue su?icient to interfere with i
or cause gagging or choking. ‘

the form of ridges, corrugations or protuberance-s
these'projections preferably increase in thickness
and width from the central portion 4 to substan-- 45
tially the point 5 which is adjacent the outer
ends. The shape of these projections is such that
a vertical cross sectional viewtherethrough would _ -
be substantially elliptical, the purpose of which
is to provide a maximum contact area for engage- '50 V '
ment with the gums. while the shape of the en- ‘
tire‘ device lends itself to the contour of the
dental arches and permits the central portion 4
thereof to be placed or located intermediate the
anterior teeth which have already erupted. The 55 L I
