Forming Necks or Tops on Glass Bottles or other Articles
and Appliances therefor.
JOHN ARMSTRONG Civil Engineer 11 Queen Victoria Street London, E.C. do
hereby declare the nature of this invention to be as follows:-
This invention is for the purpose of forming and finishing the necks or tops of
two or more glass bottles or other articles at the same time and consists of two or
more grippers or holders, such as are used at present for gripping or holding an
article such as a bottle after it has been blown and for re-heating. These grippers are
constructed on a frame and geared together at convenient distances apart so that they
revolve at the same rate, being propelled by a pulley attached behind the frame. This
frame may be suspended or mounted on a table with sliding or quadrant movement.
The grippers are made to open & close by one simultaneous action by means of a
lever to which each gripper is connected. This frame with grippers hold the bottles
or other articles by the bottom for the purpose of re-heating the neck or top and
afterwards as will be shown for holding the article while shaping the necks or tops.
For this purpose are connected together two or more shaping tongs, or moulds such
as are at present used to form necks on bottles or tops on glass articles. These are
connected on a frame and by a lever to which each pair of tongs or moulds are
attached, they simultaneously form the mouths or tops on the articles presented to
them by the grippers already described. These moulds or tongs may be geared
together and propelled similar to the grippers if necessary for the purpose of
revolution, or they may be stationary and mounted on a table with sliding or quadrant
motions.

I, JOHN ARMSTRONG, of 11, Queen Victoria Street, in the city of London, Civil
Engineer, 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 :-
-
My invention relates to the manufacture of glass bottles and other glass articles,
and has for its object to provide means for forming and finishing the necks or tops of
two or more of such articles simultaneously by the aid of a single workman, whereby
a saving of labor is effected and the cost of production thereby reduced.
My said invention consists essentially in the employment of grippers adapted to
hold and rotate two or more bottles at one time, in combination with two or more sets
of shaping tongs or moulds; the said grippers and shaping tongs or moulds being
moveable relatively to each other, so that the necks or tops of all the articles can be
shaped simultaneously.
In the accompanying drawings I have shown my invention as applied for forming
or shaping the necks of three bottles simultaneously.
Figure 1 is a side elevation of apparatus suitable for carrying out my invention,
and
Figure 2 is a plan of the same, the grippers being removed.
Figure 3 is a section on the line a, a, figure 2.
Figure 4 is a sectional side elevation of one of the shaping tongs and its connected
parts drawn to an enlarged scale, and
Figure 5 is an end view of the said shaping tongs.
Figure 6 is a plan partly in section of the grippers detached and drawn to an
enlarged scale.
Figure 7 is a section of the same on the line y, y, and
Figure 8 is a view of a detail.
a is the bed or table of the apparatus, and 6 is a stand upon which the same is
supported.
c is the head of the machine in which are mounted three spindles d, d, d which are
geared together by the wheels e, e, e and adapted to be rotated by the operator through
the medium of the handle, the shaft g. the sprocket wheels h, h¹ (one of which is
keyed on an extension of one of the shafts d) and the chain i.
are the shaping tongs, which at their rear ends are secured to the shafts d, d, d
so as to rotate therewith, and which at their front ends are provided with nozzles k, k, k
terminating in collars k¹, k¹, k², and of a size corresponding to the internal diameter of
the necks of the bottles in course of manufacture.
:
,, are the palms which constitute part of the said tongs and which serve to form
the exterior of the bottle neck in a well known manner. These palms are attached to
the other parts of the tongs by spring arms 1, 1, 1, as shown most clearly in
figure 4.
These palms are closed upon the bottle necks or pressed together by means of a
block m sliding in guides n, n on the head and acting on the arms 1, 1, 1, the said
block being actuated by a lever n¹ pivotted to the stand b and connected by a cord o
C

page_text: to a treadle p near to the position occupied by the operator. With this arrangement
when the said treadle is depressed, the block m will be moved to close the palms,
as indicated by dotted lines in figures 4 and 5.
g is the gripping apparatus, which comprises a number of shafts r, ", " mounted in
bearings in a plates and connected together at one end by gear wheels t, t, t¹, t¹.
The other ends of the shafts, r, carry sockets u, u, u which serve to receive and
hold the bottles during the finishing operation, the said sockets being divided longi-
tudinally, as at v, figures 6 and 7, so as to enable them to spring lightly to hold bottles
firmly.
The central shaft r is elongated or extended to serve as a handle for rotating the
shafts, r, with their sockets.
a,
The plate s is adapted to slide in guides w, w (figure 1) formned on the bed or table
so that the gripping apparatus can be readily moved to bring the bottles which it
carries into connection with the shaping tongs.
The operation of my apparatus is as follows, that is to say ;-After the bottles have
been blown, either by ordinary means or, as is preferable, by means of the apparatus
described in the Specification of former Letters patent granted to me dated
11th December A.D. 1886, No. 16268, and before they are broken off or detached
from the blow-tubes, they are inserted into the sockets u, u, u, as shown in figure 6,
so that the necks project. The bottles whilst still in the sockets are re-heated, a
constant rotary motion being imparted to them by means of the handle r' to prevent
the bottle necks from bending or becoming deformed.
When the necks are properly heated, the gripping apparatus is placed on the
guides w, w, as shown in figure 1, and pushed thereon until the bottle necks pass over
the nozzles k, k, k. Rotary motion is then imparted to the said tongs from the
handle and at the same time the treadle is depressed to cause the block m to close
the palms together.
As soon as the shaping is finished, the treadle is released and the bottles are
removed from the sockets and substituted by others, the operations herein before
described being then repeated.
I wish it understood that I do not confine my invention to the details of con-
struction hereinbefore described, as it is obvious that the same may be considerably
modified without departing from the nature of the said invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. A New kind of apparatus, such as herein described, for forming and finishing
the necks of glass bottles and for similar purposes, the said apparatus comprising a
holder or gripper adapted to contain and rotate two or more bottles at the same
time, in combination with two or more sets of shaping tongs adapted to be rotated
by mechanical means, substantially as setforth.
2. The combination of two or more sets of shaping tongs geared together or
otherwise arranged so as to rotate simultaneously, with means for closing the palms
of such tongs together, substantially as, and for the purpose, described.
3. The improved apparatus herein before described and illustrated in the accom-
panying drawings, for forming tops or necks of glass bottles and other articles, as
setforth.
