PROVISIONAL SPECIFICATION left by the said Louis Antoine Victor
Pellegrin at the Office of the Commissioners of Patents on the 20th October
1882.
LOUIS ANTOINE VICTOR PELLEGRIN, of Toulon-sur-Mer France, at present
residing in West Kensington, London, W. "AN IMPROVED APPARATUS FOR THE
ADMINISTRATION OF ALIMENTARY FLUIDS AND SEMI-FLUIDS AND FOR OTHER
PURPOSES TO WHICH THE SAID APPARATUS IS APPLICABLE
دو
The apparatus according to my Invention consists of two main portions which
comprise Firstly a bottle or vessel of novel form and construction to contain the
fluid or semi-fluid and Secondly of a novel arrangement, combination and con-
struction of parts forming the tubular suction portion of the said apparatus or the
conduit (with fittings hereinafter described in detail) by means of which the
contents of the bottle are withdrawn.
In the accompanying sheet of drawings illustrative of my said Invention, Figure 1
shews a section of the bottle on the line CD of Figure 2. Figure 3 is a transverse
section of the bottle taken on the line A. B Figure 1, and Figure 2 is a top view
of the bottle lying flat. The interior of the bottle is so moulded that all the
contents gravitate to that part where the glass tube a terminates; this is a novel
feature of great importance, as by this construction the contents may be withdrawn
from the bottle to the very last drop, quite irrespective of the flat or upright
position of the bottle when the apparatus is being used. Not only so, but the
improved bottle is more elegant in form, more portable and yet stronger than any
hitherto placed before the public. There is no india rubber tubing inside the bottle

page_text: but only the glass tube a shewn detached at Figure 12, which has at the top a small
button or flange piece a' blown in one piece with the tube; the said flange piece a¹
I also prefer to form with a shoulder piece underneath to serve as a stopper as
shewn in the section of Figure 12.-When the tube is inserted in the bottle, the
flange piece a rests as shewn on the top of the fixed collar e. by preference of
ivory surrounding the neck of the bottle and kept in position there by the
shoulder piece or fitting stopper portion of a'. This arrangement prevents the
tube from shaking about in the bottle, a drawback which attaches to all other
feeding bottles. The bottle is charged through the opening b which is fitted air
and fluid-tight with plug c, made of such a material as shall not in any way affect
or taint the milk or other alimentary fluid or semi-fluid contained in the bottle.
This feature applies also to all the other interior parts of the bottle and forms an
important and novel advantage from a hygenic point of view. The opening b
serves also to allow of the ready and thorough cleansing of the bottle when
required. Referring to the suction portion of the apparatus, the neck of the bottle
is provided with a fixed collar piece e on to which is screwed the cap piece C, by
preference of ivory, this is shewn fitted and mounted complete in Figure 4, and is
also shown at Figures 7 and 8. The cap piece C when screwed "home" rests on
the button a¹ of the glass tube a, and it has another hole screwed at the top of it
to allow of the nipple piece g (also by preference of ivory) being adapted to it.
The top of the nipple piece is formed as shewn so as to necessitate the india
rubber suction tube f being stretched over it there; and at the bottom of tlie said.
nipple the india rubber tube is there forced into the recess or circular channel g¹
so as to ensure a perfectly air and fluid-tight joint when the several parts of the
mountings at the neck of the bottle are screwed together.
This arrangement also, ensures the glass tube a being always kept, at the
requisite angle to allow of the passage of the contents of the bottle through the
tube.
Referring to Figure 7, the tent end of the indin rubber suction tube f consists of
five distinct parts, namely the teat i, the shield or guard disc j, a nipple piece g
corresponding to that already described in connection with the mountings at the
other end of a connector (by preference of ivory) h, and another nipple k. The
connector (shown in detail in Figure C) is screwed inside throughout its entire
length. The nipple is screwed into the lower half of the connector h, and the
nipple g to the upper half, both being clamped between the shield ; as shewn,
and the india rubber tube is drawn over and seenred similarly at the joints at this
part to the manner already described in reference to the connection made at the
neck of the bottle. Provision is also made for the attachment of nipples of varying
internal diameter to allow of the passage of fluids or semi-fluids of different
consistencies. I prefer to make the india rubber tube of larger internal diameter
than in those of ordinary feeding bottles; the flow, through the said tube f being
regulated by the teat i.
The views Figures 9,. 10 and 11 are details of the teat and attachments, which
are in themselves, self-explanatory,
I wish it to be particularly understood that by my Invention I also entirely
dispense with the use of cork, which is so very objectionable both from a sanitary
and a hygenic point of view.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Louis Antoine Victor Pellegrin in the Great Seal Patent Office on
the 16th April 1883.
LOUIS ANTOINE VICTOR PELLEGRIN of Toulon-sur-Mer France at present
residing in West Kensington London, W. " AN IMPROVED APPARATUS FOR THE
ADMINISTRATION QF ALIMENTARY FLUIDS AND SEMI-FLUIDS AND FOR OTHER
PURPOSES TO WHICH THE SAID APPARATUS IS APPLICABLE."
My improvements relate more particularly to the connections of the tubular
parts of an infants feeding bottle, such connections being applicable to all kinds of
Hexible tubes, where it is desired to make a strong joint without the use of binding
wire or dips as hitherto has been the practice.
In constructing my improved apparatus for the administration of alimentary
fluids and semi-fluids I prefer to make the vessel or bottle for containing the fluid
or semi-fluids of a flat pear shaped form with its lower side constructed so that the
contents drain to one point. The neck of the bottle is placed at such an angle
that the suction tube when in position reaches the lowest portion of the bottle in
order that all the fluid or semi-Buid it contains may be withdrawn. The suction
tube and stopper are made of glass or other suitable non-corrosive material, the
former passing through and accurately fitting in the latter, which also is fitted fluid
and air tiglit in the neck of the bottle; near the end the suction tube a flange is
provided to enable it to be fixed securely in its place. On the outside of the neck
of the bottle a collar is secured, which is provided with projections for securing the
cap. The cap is attached to the bottle by some suitable means such as a screw-
thread or bayonet joint. The interior of the cap is chambered out to receive the
flange on the end of the suction tube, which it firmly secures in position. To the
outer end of the cap the exterior suction tube is secured by means of a nose-piece
or nipple having its outer end of conical form over which the india-rubber tube is
stretched. The said nose-piece or nipple has a shoulder at the base of the cone
beyond which a screw thread is formed to attach it to the cap of the feeding bottle.
The action is as follows.-Upon the india-rubber tube being drawn over the
conical end of the nose-piece or nipple, sufficient tube is left to close around the
shoulder formed at the base of the cone, the nose-piece or nipple is now screwed
into the cap (into which a suitable recess or bed is made for the base of the cone)
the result being that the tube is tightly clasped between the two surfaces with
which it comes in contact and is thus firmly secured. The other joints in the
suction and also the teat tube are secured in a similar manner.
It will be readily understood from the foregoing description of attaching flexible
tubes that this part of my invention is applicable to other purposes where it is
desired to make joints with flexible tubes or hose, and their connections also for
connecting various lengths together, such modifications being introduced to adapt
the joints to the material and form of flexible tube or hose employed.
In order that my invention may be more fully understood, I will now proceed
more particularly to describe same, and for this purpose shall refer to the several
figures on the annexed sheet of drawings, like letters of reference referring to like
parts.

page_text: DESCRIPTION OF DRAWINGS
Fig 1. represents a side elevation of a feeding bottle, the neck portion of which
is shewn in section. The lower side of the bottle is formed so that the contents
will drain to the end of the suction tube. A is the bottle having its neck B formed
at an angle. C is the stopper fitted with a suction tube D reaching to the lower
right hand side of the bottle, E is a collar securely attached to the neck having
projections for securing the cap formed on it. Fig 2' represents the bottle in plan:
Fig-2a is an elevation and plan of the stopper C. Fig 3, is a section of the cap
which is attached to the bottle by any suitable means; the one shewn being what
is commonly known as a bayonet joint. F is the cap in which a suitable chamber.
is formed for the reception of the flange on the end of the suction tube D. G is the
flexible suction tube attached to the cap F by means of the nipple or nose-piece EL.
Figs and 5 represent respectively plan and elevation of the collar E which is
securely attached to the neck B of the bottle A. Fig 6 shews the whole of the
flexible suction tube and its connections in élevation, a section of the central
connecting piece being shown at Fig 7, and a section of the teat and its connection.
with the said tube at Big 8. Referring to Fig 7, H, H, are two nipples or nose-
pieces having the suction tubes G, G, on their conical ends the smaller ends being
screwed into a connecting piece J. On referring to Fig 8 the same method of
securing the tube is carried out, a slight modification being introduced here in the
case of securing the nipple K whereby the guard plate L serves as one of the
abutting surfaces for securing the nipple, Fig 9 shews three nipples or nose-pieces II
of varying internal diameter for regulating the supply of the fluid. Fig 10 shows
tliree nipples or nose-pieces in elevation of modified forms. Fig 11 shews in half
elevation and section another modification of my joint screw adapted for tubes of
larger diameter. In this case the nipple or nose-pièce I has formed on a portion
of its outer surface a screw-thread on which a collar or wing nut M is screwed on
the inner side of which an annular groove or recess is formed for the reception of
suitable packing N such as india rubber for rendering the joint perfectly fluid or
air tight when the tube G or hose employed is not of a sufficiently elastic nature.
In order to make such joints more easily I cut the ends of the tubes G to be con-
nected as shewn in Fig 11 and pass a piece of wire or cord through them so as t
draw their extremities together. Fig 12 shews a similar joint screw to Fig. 11
there being a slight modification in the details which is shewn at M' the object
being in this case to have a longer portion of the tube G clasped between the
abutting surfaces. Fig 13 shews a joint screw in half elevation and section suitable
for gas tubes. M forms the abutement into which the nipple or nose-piece H.
is screwed and thereby securely clasping the tube G. An ordinary union with
butterfly nut is shewn for attaching to any suitable connection.
Fig 14 shews another method of constructing joints in tubes or hose and forms
a variation of the principle involved. The nipple or nose-piece H in this case is
made parallel and has a sliglit bead or swelling O formed at or near its outer end,
or a series of such may be forined. The tube G is first placed on the nipple E and
is then screwed into the coupling piece M until perfectly secure; an outer nut or
collar P is then screwed on the coupling piece M until it firmly secures the tube G
on the opposite side of the bead or swelling O on the nipple or nose-piece H, in this
manner a double clasp of great strength is obtained, and is adapted for tubes
subjected to high pressure.
Having now fully described the nature of my invention and in what manner the
same may be carried into effect, I wish it to be particularly understood that I do
not make any claim to the form of feeding bottle and arrangement of internal suction
tube shewn, as I have since discovered that the same is not new; nor do I confi.e
myself to the precise details of forming the joints in the outer suction tubes of such

page_text: apparatus, and modifications thereof as herein described and illustrated, as many
variations thereof may be adopted without departing from the principle of my
invention, but what I believe to be novel and original and claim as the Invention
to be secured to me by and in terms of the hereinbefore in part recited Letters
Patent is
1. The principle of securing flexible tubes or hose to their connections as
substantially described and illustrated by Fig. 3. 7. 8. 11. 12. 13 & 14. in the
foregoing Specification.
In witness whereof I the said Louis Antoine Victor Pellegrin have hereunto
set my haud and seal this fourteenth day of April in the year of our Lord
1883.
