page_text: I JOHN LAKEMAN of 24 Hampton Road Forest Gate in the County of Essex
Commission Agent do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide an efficient means for preventing the
accidental disconnection of the teat from the union or coupling piece which
connects it with the india rubber tube thereby obviating the inconveniences
commonly arising from that cause, and at the same time preventing injury to the
teat by the cutting or abrading action of the hard shield. .
For this purpose I form the shield of any suitable hard material and with a
central hole therein as usual, but I form such hole of larger diameter than the
neck of the teat when it is expanded by being placed upon the coupling piece or
union and I cement or otherwise attach to one or both sides of the shield, but
preferably to one side only, a disc of india rubber or other suitable, material
perforated at its centre with a hole of a smaller diameter than that in the shield.
By these means when the teat is placed upon the union or coupling piece and.
my compound shield is placed in position the disc of india rubber or other material
will exert an elastic force to, press the teat into the usual groove in the union or
coupling piece and will thus securely connect the parts together and will not in
any way cut or injure the teat in the operation of placing the teat upon or
removing it from the coupling piece or union.

Commission Agent 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 my invention is to provide an efficient means for preventing the
accidental disconnection of the teat from the union or coupling piece which
connects it with the india rubber tube thereby obviating the inconveniences
commonly arising from that cause and at the same time preventing injury to the
teat by the cutting or abrading action of the hard shield."
For this purpose I form the shield of any suitable hard material and with a
central hole therein as usual, but I form such hole of larger diameter than the
neck of the teat when it is expanded by being placed upon the coupling piece or
union and I cement or otherwise attach to one or both sides of the shield, but
preferably to one side only, a dise of india rubber perforated at its centre with a
hole of a smaller diameter than that in the shield..
By these means when the teat is placed upon the union or coupling piece and my
compound shield is placed in position the disc of india rubber will exert an elastic
force to press the teat into the usual groove in the union or coupling piece and
will thus securely connect the parts together, and will not in any way cut or injure
the teat in the operation of placing the teat upon or removing it from the coupling
piece or union.
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an exterior view and Figure 2 is a sectional view of parts of feeding
bottle fittings showing my invention applied thereto. Figure 3 is a cross section
and Figures 4 and 5 are upper and under side views of the shield separately and
Figure 6 is a sectional view of parts drawn to a larger scale, a is a part of the
suction tube of a feeding bottle, b is the union or coupling piece which connects
the teat c with the suction tube a and my invention consists of means for
preventing the accidental disconnection of the teat c from the union or coupling
piece band at the same time preventing injury to the teat by the cutting or
abrading action of the hard shield d.
In carrying my invention into effect I form the shield d of any suitable hard
material and with a central hole therein as usual but I form such hole of larger
diameter than that of the neck of the teat when it is expanded by being placed
upon the coupling piece or union b and I cement or otherwise attach to one or both
sides of the shield d but preferably to one side only a disc of india rubber
perforated at its centre with a hole of smaller diameter than that in the shield d.

page_text: According to the arrangement shown in the drawings the shield d is formed with a
recess d in one side thereof to receive the rubber disc d' and this recess at its outer
edge terminates in an undercut circumferential groove d³.
The metal disc d' when placed in position upon the rubber disc d' is of a dished
form and of such diameter as to allow it to pass freely into the recess d³ in the
shield d; it is then pressed and somewhat flattened until it assumes the position
shown in the drawings with its outer edge taking into the undercut groove d³
whereby the rubber disc d' is secured firmly in position. I have shown this method
of retaining the rubber disc in position merely as an example of a form of
construction that I have found to answer well in practice, but it will be evident
that other methods may be devised for effecting the same object and that if
necessary a second or additional rubber disc d¹ may be attached to the shield d on
its other side in a similar or other suitable manner.
By these means when the teat c is placed upon the union or coupling piece b
and my compound shield is placed in position, the disc of india rubber d' will
exert an elastic force to press the teat c into the groove b¹ in the union or coupling
piece b and thus securely connect the parts together whilst at the same time the
rubber disc will prevent the teat c being cut or abraded in the operation of placing
it upon, or removing it from the coupling piece or union b.
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:
In fittings for feeding bottles the employment in connection with a shield d of a
perforated disc or discs d¹ formed of india rubber in manner substantially as
herein shown and described and for the purpose stated.
