PROVISIONAL SPECIFICATION.
Improvements in or Applicable to Feeding Bottles.
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 invention consists in improved means of regulating or stopping the flow of
liquid or food through the tubing of feeding bottles into the teat from the bottle.
For this purpose 1 provide the stopper or cap with a regulator which may consist of a
hollow or solid slide or screw inserted in the stopper or cap of the bottle; the regu-
lator has a hole or space for the passage of the tubing so that by pressing or drawing
or turning the regulator, the passage through the tube can be regulated as required
or completely closed.
The regulator can be made in glass, bone, ebonite, wood, metal, or any suitable
material.

Improvements in or Applicable to Feeding Bottles.
I, JOHN LAKEMAN, of 24 Hampton Road, Forest Gate, in the County of Essex,
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 :-
This invention consists in improved means for regulating or stopping the flow of
liquid or food through the tubing of feeding bottles into the teat from the bottle.
For this purpose I provide the stopper or cap with a regulator which may consist of
a hollow or solid slide or screw inserted in the stopper or cap of the bottle; the regu-
lator has a hole or space for the passage of the tubing so that by pressing or drawing
or turning the regulator the passage through the tube can be regulated as required or
completely closed.
The regulator can be made in glass, bone, ebonite, wood, metal, or any suitable
material.
In order that my said invention may be understood I will describe the same with
reference to the accompanying drawing in which
Figure 1 is an elevation of a feeding bottle provided with my improvements.
Figure 2 is a central vertical section of the stopper and
Figures 3, 4 and 5 are views of details.
a is the bottle, bis the stopper which as shown is screwed into the said bottle, c is
the tube and d is the teat or nipple, the latter being shewn as constructed according
to the specification of former Letters Patent granted to me and dated the 3rd day
of March 1886, No. 3052.
e is the regulator which consists of the eye f (through which the tube c passes)
having the screw shank g, Figures 3 and 4, and of the nut h, Figure 5 adapted to
work in conjunction with the said shank. This regulator is located in a slot or
recess in the stopper, and a rib or flange on the nut bears against a seat j at the
mouth of the said slot, so that when the nut is turned in the proper direction it will
draw the eye laterally to the axis of the stopper, for instance, to the position
indicated by the dotted lines in Figure 2 and thereby more or less compress the
tube c, also as indicated by dotted lines in Figure 2. The edge of the nut is
preferably milled as shewn in Figure 1 to facilitate the turning thereof.
The stopper 6 is preferably formed in one piece the recess being moulded during
the manufacture of the stopper. When, however, the stopper is made of glass or
other materials, in which it is difficult to mould such a recess, I prefer to form the
said stopper in two parts adapted to be connected together say on the dotted line k,
Figure 1. In this case the recess may be formed in any suitable manner prior to the
connection of the two parts of the stopper.

page_text: 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 the stopper of a feeding bottle of a regulator adapted to
more or less compress the tubing to control the flow of liquid through the same
substantially in the manner described.
2. The combination with the stopper of a feeding bottle, of a regulator e located in
a recess in the said stopper and comprising the eye f having the screw threaded shank,
and the nut h substantially as described.
3. A feeding bottle provided with means substantially as described with reference
to the accompanying drawing for regulating or controlling the flow of liquid through
the tube, substantially as described.
