IMPROVEMENTS IN TOOLS FOR FORMING BOTTLE MOUTHS
Year: 1885

page_text: I DAN RYLANDS of Hope Glass Works, Stairfoot, Barnsley, in the County of
York, Glass Bottle Manufacturer do hereby declare the nature of my invention for
IMPROVEMENTS IN TOOLS FOR FORMING BOTTLE MOUTHS to be as follows:-
The tool is made in the form of the ordinary bottle-maker's tongs having two
spring legs, at the ends of which are fastened the dies, the faces of such dies being
made in shape to suit the outside of mouth of bottle. Fixed between these legs
and secured at spring end of same, by means of suitable nuts is a rod or stem,
which has a bearing in a centre portion of a quadrant, the said quadrant has a slot
hole formed in either side of the rod or stein, and in these slot holes work set
screws which are screwed fast to the legs; the quadrant is made in a curve form,
the afforesaid slot-holes corresponding to such curve form, and the set screws work
loose in these slot holes, so that by closing the legs the quadrant is forced down-
wards and by releasing the saine, the spring legs open and bring the quadrant
back. Attached to the rod or stem by a suitable rivet or nut is a forked shape
piece, which is secured to a swiller by means of screws.
Having a suitable bearing in centre of this swiller is a hollow plug, which has
screw or portions of screw threads formed on outside, and vertically between such
portions of screw threads slot holes are formed, wherein fit or rest suitable dogs
having faces on their undersides, against which work corresponding raised faces
formed on a presser; the said presser fits between these dogs & works in hollow
portion of plug. The end of this presser which comes without the plug is made in
a square form on the outside, this square part fits into a square space formed in a
crossbar, which is attached to the fork shaped piece. When the legs are apart the
square portion of the presser comes within the square space in cross-bar and so
prevents the presser revolving and the presser having grooves wherein fit projections
which are on the plug, said plug is prevented from revolving also. The presser has
a round hole formed in centre of square portion to suit a connecting piece, one
end of which is made to fit this hole, and is able freely to revolve therein, but by
means of a groove & pin connection the said presser is made either to travel in or
out of the plug, according to the movement of the connecting piece The other
end of the connecting piece is made in the form of a fork and is secured to the
quadrant by means of set screws.
The dogs have a suitable spring or springs connected to them in such a way so
that whenever the raised faces of the presser are clear of them (which is always

page_text: when the spring legs are apart) they are forced by such spring or springs: below
the bottom of the threads formed on plug. The plug has preferably a flange
bearing in the swiller, and a circular plate is screwed to the swiller to prevent the
plug leaving such bearing.
Having thus far described the details of my hereinbefore described improved
Tool. I will now set forth the particular way the same has to be worked.
After placing the ring of molten glass around the top of the neck of the bottle,
in the usual way; I place the hollow plug in mouth of such bottle, I then press to
the legs of the tongs and by means of the quadrant and connecting piece, this
forces the presser into hollow plug, when the raised faces of said presser come in
contact with the corresponding faces on the dogs thus causing said dogs to protrude
or press out and so to form the required vertical or other slots in bottle mouth, and
the plug with the screw or portions of screw threads thereon forms the screw or
portions of screw threads in bottle mouth: I then revolve the bottle by means of
a pontil, and the presser having the square end clear of the square space in cross-
bar is permitted with the plug to revolve simultaneously with the bottle. After a
satisfactorily formed mouth has been made I release the legs, the springing apart
of which causes the raised faces of the presser to withdraw from the plug, and the
dogs are by means of the spring or springs embedded beneath the bottom portion
of the screw threads; the square portion of presser thus enters the square space in
crossbar, and so prevents both it and the plug revolving. By still revolving the
bottle the screw threads or portions of threads on the plug forces the bottle there-
from and so completes the operation of forming the bottle mouth with vertical or
other slots and portions of screw threads as may be required.

Glass Bottle manufacturer do hereby declare the nature of my Invention for
IMPROVEMENTS IN TOOLS FOR FORMING BOTTLE MOUTHS, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention relates to a new and improved tool used for the purpose of formning
bottle mouths with vertical or other slots, and portions of screw threads formed
therein.
Fig 1. is an elevation of the said improved tool with certain portions shown
in section, the dies B, B, are shown apart, and the presser N, withdrawn from
plug K.
Fig. 2. is an elevation of portion of said tool showing the dies B B. closed, and
in contact with section of bottle mouth. The tool is held in this position during
the formation of bottle mouth.
Fig. 3. is a longitudinal section along the line 2. 2. of fig. 2.
Fig. 4. is a cross section on the line 3. 3. of fig. 1.
Fig 5 is a cross section on the line 4, 4. of fig. 3.
Fig 6 is a cross section on the line 5, 5. of fig 1.
Fig 7 is a back elevation of the swiller J. with the circular plate Y. removed.
The same letters designate the same particular parts of the tool in each fig.
The tool is made in the form of the ordinary bottle-makers tongs, with two
legs A, A, at the extremities of which are secured the dies B, B, as shown in figs 1.
and 2. The dies B, B, have faces C, C, which are made in form to suit the required
shape of outside of bottle mouth.
A rod or stem E, is fixed between the legs A, A, and secured to the spring end a.
by means of the nuts D, D. The rod E, has a bearing e, in the quadrant F. The
quadrant F. has slot holes f. f. wherein work the set screws G, G, which are
screwed into the legs A, A. By refering to fig. 1. it will be readily seen, that by
pressing to the legs A. A. (and so bringing them into position shown at fig. 2.) the
quadrant F. is made to travel towards the dies B, B, and occupy the position shown at
fig. 2, and by releasing the legs A, A, they spring apart, and the set screws G, G.
working in the slot holes f,f bring the quadrant F. back to position shown at fig. 1,
The forked shaped piece H. (fig. 3.) is attached to the rod E. by the rivet h, and the
swiller J. is secured to the fork shape piece E. by means of the screws I, I. The
hollow plug K, has a flange bearing k, in the swiller J. wherein it may easily
revolve, and is prevented from leaving such bearing by means of the circular
plate Y. which is attached to the swiller J. by means of the screws Z. Z.
:
The hollow plug K, has screw or portions of screw threads 1, 1, 1, 1, (figs 1, 2, 3, 5,
and 6) formed on outside; between the portions of which slot holes L, L, L, L, are
formed, which will be well understood by refering to fig. 6. The dogs M, M, M, M,
work in the slot holes L, L, L, L, and have faces m, m, m, m, formed on their
underside, and projections m² m² m² m², which work or slide in grooves k' kɩ k¹ k¹´

page_text: The
(figs 4 and 7) formed on the hollow plug K. The pins P, are either made with or
attached to the dogs M, and have placed around them the spring X, clearly shown
at fig. 4, the spring X is attached to the plug K, by means of the stud x.
presser N, has raised faces n, n, n, n, which work against the faces m, m, m, m,
formed on underside of dogs M, M, M, M. The said presser N fits between the
dogs M, M, M, M, and works in hollow portion O, of the plug K.
The end of the presser N, is made in a square form p; this square end p, fits into
the square space q. (formed in cross-bar Q) when the legs A, A. are in position
shown at fig. 1, but when the legs A, A, are in position shown at fig 2, the square
end p, is clear of the square space q. as shown at fig. 3. The cross-bar Q, is either
made with or attached to the fork shape piece H, (fig. 3.). The presser, N, has
grooves or channels j. j..j. j. (figs 4 and 5) wherein fit the projections i, i, i, i,
formed on plug K. by this means the plug K, is prevented from revolving unless
the presser N, also revolves; so that whenever the square part p, of the presser N,
is within the square space g. of the cross-bar Q, (which is always when the
legs A, A, are apart as shown at fig. 1.) the presser N, is prevented from revolving,
and necessarily the dogs M, M, M, M, also; as will be well understood. The
presser N, has a round hole ", wherein fits the end 8, of the connecting piece S.
which has an annular groove or neck t. wherein fits the pin u; by means of this
connection the plug N, is able freely to revolve on portion 8, of the connecting
piece S, but at the same time is obliged to travel either in or out of the hollow
plug K. according to the movement of the connecting piece S. The connecting
piece S, terminates in the form shown at fig. 1. having two prongs v. v. which are
secured to the quadrant F, by means of the set screws w, w.
Whenever the faces n, of the presser N, are clear of the faces m, of the dogs M,
(which is always when the legs A, A, are in position shown at fig 1.) the spring X
(6g 4) presses the dogs M, inward so that the top surfaces of the dogs M, come
below the bottom of threads 1, (figs 1, and 6); but when the legs A, A, are pressed
together and obtain the position shown in fig. 2. the movement of the quadrant F,
causes the connecting piece S, to force presser N, into hollow plug K, when the
faces of presser N, come in contact with the faces m of dogs M, thus pressing
the dogs M, outward, so that the top surfaces of the dogs M, protrude or extend
behond the tops of the threads l, as shown in figs 2. 3 and 5.
Having thus far described the details, and in what manner the same are put
together so as to form my improved tool. I will now set forth the particular way
of using such tool for forming bottle mouths.
After placing a ring of molten glass around the top portion of neck of a bottle
which has just been blown, I place the hollow plug K, in mouth or unfinished
mouth of such bottle. I then press to the legs A, A, until they obtain the position
shown at fig. 2. this operation causes the quadrant F, and connecting piece S. to
force the presser N, into hollow plug K, thus causing raised faces n, of presser N,
to come in contact with the faces m, of the dogs M, and so causes the top surfaces
of the said dogs M, to protrude or extend behond the tops of threads 1, (figs 2, 3
and 5) by this means vertical or other slots are formed in mouth of bottle, and the
portions of threads 1, form corresponding portions of threads in bottle mouth.
After pressing to the legs A, A; until they obtain the position shown at fig 2,
I revolve the bottle by means of a pontil, in the usual way; the square portion p,
of the presser N, being now clear of the square hole or space q, in cross-bar Q; the
presser N plug K, with the dogs M, revolve simultaneously with the bottle.
After a satisfactorily mouth has been thus formed; I release the legs A, A, which
spring apart, and cause the quadrant F, (by means of the connecting piece S,) to
withdraw the faces n, of the presser N, from the faces m, of the dogs M, when by
action of the spring X, the dogs M, become embedded in the slot-holes L. (fig. 6.)
and their top surfaces come below the bottom of threads 1, (figs 1 and 6); also the
square portion p, of the presser N, enters the square hole q, in the cross-bar Q, and
is thus prevented from revolving, and the plug N, having channels j. wherein fit

page_text: the projections i. (which are formed on plug K) the plug K is also prevented from
revolving and necessarily also the dogs M, as shown at fig. 1.
After releasing the legs A, A, as hereinbefore described, I continue to revolve
the bottle, by means of the aforesaid pontil, by so doing the portions of screw
threads, force the bottle mouth from the plug K, but it must be however
understood that the bottle must be revolved in the direction to suit the threads l,
so that the said threads 7, unscrew from mouth of bottle. This completes the
operation of forming the bottle mouth having vertical, or other slots and portions
of screw threads as the case may be required.
I would here remark that I do not limit myself to any definite number of
dogs M, nither to any definite number of portions of screw threads l, I show four
of each in the drawings but more or less may be used as the case may require,
nither do I bind myself to any particular shape of dogs M.
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
The special combination of Presser N, with the dogs M, and the cut portions of
threads; substantially as herein described and shown at Figs. 1. to 7. in the
accompanying drawings.
