Improvements in and in the Mode of Manufacturing “Unions" for
Connecting Teats to Feeding Bottles and the like.

I, ALEXANDER RICHMOND STOCKER, of 69, Ambler Road; Finsbury Park, London,
N., Manufacturer do hereby declare the nature of this invention to be as
follows:-
My invention consists in constructing "unions" to be used with infants feeding
bottles and the like so that when the teats and shields are fitted thereto the
parts will not become detached while in use. I accomplish this in the following
manner:
"
"
union
"
Preferably but not necessarily I dispense with that part of the teat known
as the "roll," I then place it on to the
in the ordinary way, the ring
at this end of the union is somewhat larger than either the centre or end ring
intended to receive the india rubber tube. I now place on the shield from the
other or uncovered end of the "union" the hole in such shield being a trifle larger
than the centre ring of the "union" and smaller than the ring already covered
by the teat so that it cannot pass over when there will remain a space of about
16 of an inch between the centre ring and the shield into which space I spring
an india rubber washer or ring which will prevent the shield and teat becoming
detached except by removing the india rubber ring or washer.
The method I employ to produce my improved "unions" out of molten glass
consist in the use of special dies or moulds which have been previously shaped to
their desired form so as to produce the desirably shaped "unions" in them
horizontally by cutters or otherwise in conjunction with cores or pins for forming
the bores of the unions."

The moulds are made in two halves fixed or jointed together by a hinge so
of an ordinary press
as to open and close readily and screwed on to the "saddle
used in glass works. The top half of the die or mould has a "gate" or cavity
into which the molten glass is intended to be introduced such " gate" leads also
by a smaller gate" into the several unions" already sunk in the die or mould
say 12 in number, 6 on each side.

The cores or pins are now pressed up to a stop in the die or mould when the
molten glass is introduced into the "gate" or cavity and pressure exerted thereon

page_text: Improvements in and in the Mode of Manufacturing "Unions" for
Connecting Teats to Feeding Bottles and the like.
I, ALEXANDER RICHMOND STOCKER, of 69, Ambler Road, Finsbury Park, London,
N., Manufacturer, 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, reference being had to the accompanying
drawings and to the letters and figures marked thereon, that is to say:-
My invention consists in constructing “unions” to be used with infants feeding
bottles, and the like, so that when the teats and shields are fitted thereto the
parts will not become detached while in use. I accomplish this in the following
manner:-
"
Preferably, but not necessarily, I dispense with that part of the teat known
as the "roll." I then place it on the union" in the ordinary way, the ring
at this end of the "union" is somewhat larger than either the centre or end ring
intended to receive the india rubber tube. I now place on the shield from the
other, or uncovered end of the "union" the hole in such shield being a trifle larger
than the centre ring of the union and smaller than the ring already covered
by the teat so that it cannot pass over, when there will remain a space of about
16 of an inch between the centre ring and the shield, into which space I spring
an india rubber washer or ring which will prevent the shield and teat becoming
detached except by removing the india rubber ring or washer.
66
The method I employ to produce my improved "unions" out of molten glass
consists in the use of special dies or moulds which have been previously shaped to
their desired form, so as to produce the desirably shaped unions in them
horizontally, by cutters or otherwise in conjunction with cores or pins fór forming
the bores of the unions."
66
The moulds are made in two halves, fixed or jointed together by a hinge, so
as to open and close readily, and screwed on to the "saddle" of an ordinary press
úsed in glass works. Or the said moulds may slide to and fro, under the press,
on rails. The top half of the die or mould has a "gate" or cavity into which
the molten glass is intended to be introduced, such "gate" leads also by a smaller
gate" into several "unions" already sunk in the die or mould, say 12 in number,
6 on each side.
"
The cores or pins are now pressed up to a stop in the die or mould, when the
molten glass is introduced into the "gate or cavity and pressure exerted thereon
by the plunger of the press, the "unions" then according to the number, will
have been formed, when the cores or pins are instantly withdrawn by the aid
of toothed wheels, or levers &c., before the molten glass has time to set or chill.
The saddle of the press is then withdrawn from under the plunger of the press,
the die or mould opened, and the "unions" withdrawn, and the operation repeated.
The "unions," when taken from the mould will be attached to the overplus of glass
left in the " gate of the mould when, after having been passed through the
annealing oven, they are broken off, and cut down in the usual way of cutting
glass. They are then ready for the market.
"
And in order that my invention may be fully understood, proceed to describe
the same, with reference to the accompanying drawings, in which similar letters
refer to similar parts.
Fig. 1 is a sectional view and a plan of my improved union shewing the method
of attaching the teat thereto:
The teat a is slipped on to the larger end b, of the union a¹, after which the

page_text: shield c, is passed over the union from its uncovered end, and partly over the
end of the teat. An india rubber washer d, the hole in which is smaller than
the centre ring of the union is slipped over it as far as the shield c. The teat
and union are then complete. e, is the ordinary feeding tube. It will thus be
seen that the teat cannot become detached except by removing the india rubber
ring d.
66
"
Fig. 1 represents in plan the mould die or tool A A, which I find suitable for
the manufacture of the before mentioned glass "unions." It is of rectangular
or other suitable shape and is constructed in two halves, strongly jointed together
by a hinge, so as to be opened and closed readily and firmly. This mould die
or tool is screwed on to the "saddle" of a press such as is ordinarily used in
glass works. Or it may be made to travel to and fro, under the press, on V shaped
rails provided for the purpose. The upper half of the mould die or tool A is
provided with an opening D, technically termed a gate into which the
molten glass is poured, in the process of manufacturing the "unions." This
gate" leads, by a smaller " gate " into a number of cavities formed, cut or
sunk in the upper and lower moulds, say 12 in number, 6 on each side, although
any convenient number may be formed, according to the dimensions of said
mould die or tool. The "unions" formed in the front and rear of the mould
are intended for what are known as "soothers" only, and are not provided with
bores or passages for purposes of suction, nor indeed, can they be, in the present
construction of said mould, die, or tool.
66
In Fig. 1 the mould die or tool A A is shewn closed, the upper half being
firmly gripped to the lower by a lever or catch C. In this position it is ready to
receive the molten glass which is to be forced into the several cavities in the
upper and lower portions of the mould, die, or tool. Side spring clutch levers B B,
actuate a bar (on each side of the mould die or tool) in which are fixed by means
of screws a corresponding number of pins or cores (which move within tubes)
and which form the passages in the "unions." The said bars are attached to
the sides by loose or adjustable joints, thus enabling them to be closed or with-
drawn parallel to each other and at right angles to the sides of the mould, die,
or tool.
Fig. 2 represents the mould die or tool A A, open with the side spring clutch
levers B B moved outwards. Fig. 3 is a side elevation thereof, partly in section.
Fig. 4 is a fragmentary plan (on an enlarged scale) of one corner of the lower
mould A. Fig. 5 is also a fragmentary plan, partly in section of three of the
cores or pins F, with their sleeves or tubes F. The pins are held in position
by screws J. The dotted circles represent the oiling holes above the mould.
Fig. 6 is an elevation and plan of the plunger, and Fig. 7 is a perspective view
of one of the "unions" finished and ready for use.
:-
In carrying out my invention I proceed as follows:-
The mould A, A, having been first closed down and locked as shewn in Fig. 1,
by means of the lever or catch C, the molten glass is poured into the “ gate'
or cavity D, and pressure exerted thereon by the plunger shewn in Fig. 6, which
forces the molten glass into the moulds (one of which is seen in Fig. 4). Imme-
diately after this operation, and before the glass has had time to set or chill, the
side spring clutch levers B B are drawn outwards, as far as the stop screws E, thereby
drawing the cores or pins F, (which are shewn in detail in Fig. 5) out of the
unions. When this has been done, the mould is unlocked and opened, and the
handle G, is turned to the right, thereby partly revolving a cam H. which raises
a "lift" I, (shewn partly in section in Fig. 3) which, in turn, partly raises the
casting out of the mould. The "unions" will have an excess of glass attached
to them, from which they are broken off, after the casting has been passed through
the annealing furnace.
The casting having been removed, the handles B, B, and G, are returned to
their initial positions, the mould A, A, closed, and locked, and the operation
repeated as before.
