IMPROVEMENTS IN FEEDING BOTTLES
Year: 1880

page_text: LETTERS PATENT to George Wells, of 12, North Street, in the City of West-
minster, Civil Engineer, for an Invention of "IMPROVEMENTS IN FEEDING
BOTTLES."
PROVISIONAL SPECIFICATION left by the said George Wells at the Office of
the Commissioners of Patents on the 13th April 1880.

"IMPROVEMENTS IN FEEDING BOTTLES."
My Invention has for its object the regulation or limitation of the supply of food
from the bottle to the feeding tube by controlling the action of the valve so as to
admit the food into the feeding tube in the quantity required.
The better to describe my Invention, Figure 1 in the accompanying Drawing
represents a section of an ordinary feeding bottle fitted with one of my arrange-
ments for regulating the flow of the food, which in this case is drawn from the side.
The Figure shows the valve free for full action, but if it be required to reduce the
flow of the food the regulating. plug A is screwed further into the cap C, thereby
not only reducing the area for the inlet of the food into pipe D, but also by means
of the pin B, which is carried by or formed on the said plug A, at the same time
limiting the action of the valve E, thereby reducing the inflow of the food into the
chamber F, which is screwed into cap C, as shown. If it be not considered advisable
to reduce the area for the outlet of the food into the pipe D that part of the cap C
into which the plug A is screwed must be lengthened, so that the plug A will not
when screwed down sufficiently to limit the movement of the valve cover any
portion of the thoroughfare through the pipe D.
Figures 2 and 3 represent another arrangement, which is somewhat similar in its
action upon the valve, but it does not reduce the area for the outlet of the food into
pipe D. In this case the food is drawn through the regulating plug G, and the
control of the valve is effected by screwing the regulating plug G down into the
cap H, thereby limiting the action of the valve E and reducing the inflow of the
food to chamber F, which is scrowed into cap H, as shown.
It will readily be seen that if plug A, Figuro 1, and plug G, Figures 2 and 3, are
screwed down far enough into their respective caps (C or H) they will press upon
the valve E and stop all action.
To prevent the valve E from being lost (i.c., in the case of a ball valve) when the
feeding bottle is being cleaned it is secured, as will be seen, by a small staple cast
into the ball, through which staple a pin is passed.

"IMPROVEMENTS IN FEEDING BOTTLES.'
The said Invention has for its object the regulation or limitation of the supply
of food from the bottle to the feeding tube by controlling the action of the valve so
as to admit the food into the feeding tube in the quantities required.
The better to describe my Invention, Figure 1 in the accompanying Drawings
represents a section of an ordinary feeding bottle fitted with one of my arrange-
ments for regulating the flow of the food, which in this case is drawn from the
side.
The Figure shows the valve free for full action, but if required to reduce the flow
of the food the regulating plug A is screwed further into the neck of the bottle-
cap C, so that the pin B, which is attached to the plug A, shall limit the action of
the valve E, and thereby reduce the inflow of the food to chamber F, which is
screwed into cap C, as shown. If it be considered advisable to reduce the area for
the outlet of the food into the pipe D the plug A must be lengthened, so that when
screwed down sufficiently to control the action of the valve the area will be reduced
accordingly. Figure 2 represents another arrangement similar in its action upon
the valve, but it cannot reduce the area of the outlet of the food into pipe D. In
this case the food is drawn through the regulating plug G, which is provided with
a tubular extension, serving both for the outlet of the food, and acting in lieu of
the pin B, shown in Figure 1, to effect the control of the valve, which is done by
screwing the regulating plug G into the bottle-cap H, thereby limiting the action
of the valve E, and reducing the inflow of the food to chamber F, which is screwed
into cap H, as shown. The lower end of the tubular extension of plug G has a
notch or side opening for the passage of the food into the feeding tube. Figure 3
is a similar arrangement to that shown in Figure 1, but it has no cap fitting on the
bottle neck, nor will it allow of the reduction of the area of the outlet to pipe D.
It can be used with any feeding bottle, the pipe J being passed through the cork
or other stopper.
Figure 4 is a similar arrangement to Figure 2, but this also has no cap, and can
be used with any feeding bottlo, as in the case of Figure 3; Figures 5 and 6 are
similar to Figures 3 and 4, with the exception that the valves K are conical,
and are connected to plugs A and G. In Figure 5 the area for the outlet of
the food into pipe D can be reduced in a manner similar to that described in
Figure 1.
It will readily be seen that if the pin B (Figures 1 and 3) and plug G (Figures 3
and 4) are screwed down far enough they will press upon the valve Ĕ and stop all
action. The conical valves K, as shown in Figures 5 and 6, are represented as
being screwed down to their fullest extent. To prevent valve E being lost when
the feeding bottle is being cleansed, an inner flange is soldered at the top of chamber F,
so that the diameter of the hole is less than that of the valve, but is of sufficient
size to permit the pin B (Figures 1 and 3) and the plug G (Figures 2 and 4) to pass
through. The ball valve may also be secured by a staple cast into the ball, and
through this staple a pin (which is secured to the inlet pipe) is passed.
Having described the nature of the said Invention, and the manner of performing
the same, I declare that what I claim as the improvements in feeding bottles to be
protected by the herein before in part recited Letters Patent is,―
1st. In a feeding bottle the means of controlling and regulating at will the action
of the valve limiting the passage of the food, substantially as and for the purpose
described and shown in the Drawings.

page_text: 2nd. The combined means of controlling and regulating the action of the valve,
and of reducing the area of the outlet to the feeding tube, substantially as herein
shown and described.
In witness whereof, I, the said George Wells, have hereunto set my hand
and seal, this Eleventh day of October, in the year of our Lord One
thousand eight hundred and eighty.
GEORGE WELLS. (L.S.)
