Improvements in or connected with Artificial Teats or Nipples.
I, JAMES GEORGE INGRAM, of Felstead Street, Hackney Wick, in the County'
of Middlesex, India Rubber Manufacturer, do hereby declare the nature of this
invention to be as follows:-
:
My invention is particularly useful in the case of existing artificial teats or
nipples which may have become flattened in stock and which, without the
application of my invention thereto, are practically useless as the child cannot
obtain a proper supply of food therethrough, and a child is frequently cruelly.
tortured by such tents in consequence of its mother or nurse being ignorant of the.
fact that they are in a collapsed or faulty condition.
A child when sucking the natural nipple or teat will frequently nip or compress
it tightly between the teeth or gums; this, while causing the mother considerable
pain, will not stop the supply of food, but when an. artificial teat or nipple of even
normal form is submitted to a like pressure it becomes flattened thereby and the
supply of food is consequently shut off.
According to my invention I remedy this evil by placing in the interior of an
artificial teat a core made of india rubber or other suitable material and which is of
such form that, in the event of the teat being compressed on to the same, the
passage through the teat or nipple shall not be closed; this core may, for instance,
have a sectional form of a round or other shaped tube, or it may be formed of three
or more webs combined or not with a central tube.
By the use of a core of the above description in the interior of an artificial teat
or nipple, the supply of food cannot be cut off by any force that the child may use,,
whilst, when such core is made of india rubber, its elasticity will assist in drawing
up food from the bottle as when the pressure thereon is relaxed it will, in recovering
its normal form, again expand the teat or nipple. A child also in sucking an
artificial teat or nipple fitted with such a core will cause a movement of the said
core and thus effectually clean or clear the teat whilst in use as no fluid will be
capable of lodging therein.
:
The core will be made of such exterior form and, dimensions as to best suit the
teat to which it is to be applied; generally it is made of somewhat less external
diameter than the internal diameter of the teat or nipple, but of such size as to
require some force to push it into the interior of the nipple or teat and of length,
such as not to distort the same.
A core of this description can be readily applied to existing teats or nipples
which may already have become flattened from any cause, or they can be applied to
teats or nipples which may be hereafter made and which are of normal form.

COMPLETE SPECIFICATION.
Improvements in' or connected with Artificial Teats or Nipples.
1, JAMES GEORGE INGRAM, of Felstead Street, Hackney Wick, in the County
of Middlesex, India Rubber Manufacturer, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly described
Price 8d 1

page_text: and ascertained in and by the following statement, reference being had to the
accompanying drawings and to the figures and letters marked thereon.
My invention is particularly useful in the case of existing artificial teats or
nipples which may have become flattened in stock and which, without the
application of my invention thereto, are practically useless as the child cannot
obtain a proper supply of food therethrough, and a child is frequently cruelly
tortured by such teats in consequence of its mother or nurse being ignorant of the
fact that they are in a collapsed or faulty condition.
A child when sucking the natural nipple or teat will frequently nip or compress
it tightly between the teeth or gums; this, while causing the mother considerable
pain, will not stop the supply of food, but when an artificial teat or nipple of even
normal form is submitted to a like pressure, it becomes flattened thereby and the
supply of food is consequently shut off.
In the accompanying drawings Figure I is a vertical section and Figure 2 is a
cross section of a teat fitted with my improvement, and Figures 3, 4 and 5 are cross
sections showing different forms of cores.
According to my invention I remedy the evil above referred to by placing in the
interior of an artificial teat a, a core b made of india-rubber or other suitable
material, and which is of such form that in the event of the teat a being compressed
on to the same, the passage through the teat or nipple a shall not be closed; this
core may, for instance, have a sectional form of a round or other shaped tube, as
shown at Figure 4, or it may be formed of three or more webs combined with a
central tube or passage b¹ as shown at Figures 1, 2, 3, and 5, or the central passage 6¹
may be dispensed with.
By the use of a core of the above description in the interior of an artificial teat
or nipple, the supply of food cannot be cut off by any force that the child may use,
whilst, when such core is made of india-rubber, its elasticity will assist in drawing
up food from the bottle as when the pressure thereon is relaxed it will, in recovering
its normal form again, expand the teat or nipple. A child also in sucking an
artificial teat or nipple fitted with such a core, will cause a movement of the said
core and thus effectually clean or clear the teat whilst in use as no fluid will be
capable of lodging therein.
The core will be made of such exterior form and dimensions as to best suit the
teat to which it is to be applied; generally it is made of somewhat less external
diameter than the internal diameter of the tent or nipple, but of such size as to
require some force to push it into the interior of the nipple or teat and of length
such as not to distort the same.
A core of this description can be readily applied to existing teats or nipples
which may already have become flattened from any cause, or they can be applied to
teats or nipples which may be hereafter made and which are of normal form.
It will be readily understood that the form of core may be varied without
departing from the peculiar character of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The combination with an artificial teat or nipple, of a core constructed and
applied substantially as herein shown and described and for the purpose stated.
2. A core for an artificial teat or nipple, substantially as herein shown and
described and for the purpose stated.
