PROVISIONAL SPECIFICATION.
Improvements relating to the Fixing of Artificial Teats to Feeding
Bottles and other Supports.
I CARL GUMBART, of Königinstrasse 7, Munich in the Empire of Germany
Civil Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to teats such as are fixed upon the tubes of infants feeding
bottles or upon small handles with guard disks as false teats for the use of infants
and it consists in certain improvements relating to the means of fixing the teat and
its guard disk to the tube, handle, or other support so that there will be no
danger of these parts becoming separated or pulled apart by any effort of the
infant.
The tube, handle, or support is made or terminates in a sufficiently solid end,
slit in the form of a cross so as to be slightly elastic. The said end piece is pro-
vided with an annular recess and the guard disk has a hole through which the end
aforesaid may be sprung, the rubber teat which is hollow and provided with a
thickened edge having been previously placed over the aforesaid end. Within the
tube end, handle or support, which is hollow is inserted a plug having certain
cylindrical faces of different diameters separately by conically inclined faces.
This plug may be hollow when this construction is used to fix a teat on the tube
of a feeding bottle; for a false teat it may be solid. It is first thrust partly into
the hollow end of the tube, handle, or support so that its smaller diameter is
within that part of the tube handle or support around which is the aforesaid
annular recess. The teat is placed over the latter thus enclosing the end of the
plug, and the guard disk is slid over the teat to above the annular recess.
compressability of the teat allows the head of the plug to be pushed fully into
place, whereupon the larger cylindrical part of the plug enters the end of the
tube distends the latter and fixes the same and the teat thereon firmly in the hole
in the guard disk.
The
The plug being out of reach cannot be drawn back again by any movement of
the infant, but by a suitable tool pushed into the tube, handle, or support the end of
the plug may be reached and easily pushed back when the teat is to be taken apart
for cleaning purposes.

Improvements relating to the Fixing of Artificial Teats to Feeding

I CARL GUMBART of Königstrasse 7, Munich, in the Empire of Germany,
Civil Engineer 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:-
This invention relates to teats such as are fixed upon the tubes of infants feeding
bottles or upon small handles with guard disks as false teats for the use of infants
and it consists in certain improvements relating to the means of fixing the teat
and its guard disk to the tube, handle or other support, so that there will be no

page_text: Ordinary rubber teats are composed of the teat proper a suitably shaped hollow
piece of rubber G Fig. 1, which is closed at one end or provided with only a small
opening there; a protective or safety-disk S usually of bone or celluloid for
preventing the swallowing of the teat and a small cylinder e likewise made of solid
material, which is placed into the base end of the rubber teat G, thereby
pressing the rubber against the safety disk and uniting the rubber, cylinder and
disk in one whole. The cylindrical portion e is usually provided with a ring for
tying the teat to prevent its being lost. This combination of the different parts is
however deficient since it can without any difficulty be pulled apart by the infant,
who then has separate small parts, which he will usually swallow.
In the drawing
Fig. 1 shows the improved teat, put together, Fig. 2 the same without the
rubber teat G and with safety plug out of action.
G represents the rubber teat, S the safety disk, c the cylinder or handle and
k the improved safety piece or plug.
The cylinder handle or support is made with or terminates in a sufficiently solid
end, slit in form of a cross so as to be slightly elastic. The said end piece is
provided with an annular recess and the guard disk S has a hole through which
the end aforesaid may be sprung, the rubber teat G which is hollow and provided
with a thickened edge having been previously placed over the aforesaid end.
Within the tube end handle or support c, which is hollow, is inserted a plug k
having certain cylindrical faces of different diameters separated by conically
inclined faces.
This plug may be hollow when this construction is used to fix a teat on the
tube of a feeding bottle; for a false teat it may be solid. It is first thrust partly
into the hollow end of the tube handle, or support c, so that its smaller diameter is
within that part of the tube handle or support around which is the aforesaid
annular recess.
The teat is placed over the latter thus enclosing the end of the
plug, and the guard disk is slid over the teat to above the annular recess.
compressibility of the teat G allows the head of the plug k to be pushed fully into
place, whereupon the larger cylindrical part of the plug enters the end of the
tube c distends the latter and fixes the same and the teat thereon firmly in the
hole in the guard disk.
The
The plug being out of reach cannot be drawn back again by any movement of
the infant, but by a suitable tool pushed into the tube, handle or support e the end
of the plug may be reached and easily pushed back when the teat is to be taken
apart for cleaning purposes.
When the artificial teat is to be used in connection with the feeding bottle, first
the sucking pipe is pushed over until it covers the recess for the safety disk, then
the sucking nozzle is next put on, then the disk S is pushed over and finally the
plug is pressed in, so that a firm and airtight connection is produced.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :--
The combination with the rubber teat G, the disk S and the holder c of the
plug adapted to enter the holder e and distend the same in the manner described
and for the purpose or purposes set forth.
