I WILLIAM ROBERT LAKE of the firm of Haseltine, Lake and Co, Patent Agents
Southampton Buildings in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN APPARATUS FOR GROOVING THE NECKS
OF BOOTLES" 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 bottle-forming tools and consists in providing a bottle
forming tool with means for forming on the inner face of the mouth of a bottle, a
grove which is adapted to receive a packing or seat for an internal stopper; and
with means for indicating that the tool is fully closed.
In the accompanying drawing:
Figure 1 is a side elevation of a bottle forming tool, embodying the invention.
Figure 2 is a central longitudinal section thereof.
Figure 3 is a side elevation, at right angles to figure 1, a portion of the top
thereof being broken away.
Figure 4 is a horizontal section on the line x, x, figure 1.
Similar letters of reference indicate corresponding parts in the several figures.
A represents the jaws, and B the plug of a tool adapted for shaping or forming
the mouth and neck of a glass bottle, which tool excepting as far as my invention
is concerned, is of usual construction.
In the plug B near the base thereof is a recess a, in which are fitted bits C, C,
which in their normal positions are flush with the plug, the same being connected
with spring arms D, D, attached to the end of the tool opposite to the plug, said
arms being interposed between the handle portions of the jaws and spread or
bowing so as to force the bits inwardly against or towards each other.
The portions of the arms D are passed freely through the bar E which supports
the plug B, and each arm has firmly connected with it a screw bolt or pin F, the
latter also passing freely through the other arm, as at b, the heads of the bolts
bearing against the outside of the handle portion of the tool on opposite sides
thereof.
In order to adjust the throw of the spring arms D, and consequently of the
bits C, I apply to the bolts F, between said arms and the handle portion of the
tool or other abutments, nuts G, which are securely held by jam nuts, and in order
D.

page_text: to secure a firm connection of the ends of the bolts F with the arms D, 1 employ
jam nuts H; but other devices may be employed for said purposes.
When the tool is grasped and the plug inserted in the mouth of the bottle, the
latter being properly held, the handles are pressed together, thus advancing the
jaws A towards the neck of the bottle, and when the handles reach the nuts G and
their inward motion is continued, the spring arms D are separated or forced in
opposite directions, thus causing the bits to emerge from the recess a and project
beyond the wall of the plug B as most clearly shown in Figure 2.
The tool is now rotated, and the bits form on the inner face of the neck of the
bottle a groove corresponding to said bits, the jaws and plug performing their usual
operations. When the required groove is fully formed, the hands are permitted to
expand and the parts assume their normal positions, the bits re-entering the plug
and the jaws separating, whereby the withdrawal of the plug from the bottle or,
vice versa, may be readily accomplished, the bits presenting no obstacle thereto.
On the sides of the bar E near the ends thereof are shoulders J, which, when the
jaws are closed, abut against the jaws A, consequently when the tool is in operation
the workman observes said shoulders J, and if they are in contact with the jaws,
it is evident that the tool is fully closed and the bits are properly projected from
the plug to form the groove in the mouth of the bottle of the proper depth.
When the tool opens or assumes its normal position, the springs or spring
arms D cause the return of the bits. The handles then press against the beads of
the bolts or pins F moving the latter to full extent and causing the proper centring
of the bits in the plug. In lieu of the heads of the bolts or pins, I may form slots
therein, the same being at the outer ends and pass through them pins which are
attached to the handles, producing the same results as the heads.
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
First. In a bottle forming tool, the spring jaws A, A, in combination with spring
arms D, D, bits C, C, bar E having shoulders J, means for adjusting the throw of
the bits, and the plug B having recesses a substantially as, and for the purpose, set
forth.
Second. A bottle forming tool, having jaws A, A, spring arms D, D, plug B,
bits C, and screws F, each of said screws being provided with two nuts G and H
for connecting the jaws and bits and adjusting the throw of said bits, substantially
as, and for the purpose, set forth.
Third. A bottle forming tool, having jaws A, A, spring arms D, D, plug B,
bits C, screws F, adjusting nuts G and H, and a bar E having shoulders J, said bar
guiding the jaws A, A and limiting the closing motion thereof, substantially as, and
for the purpose, set forth.
Fourth. In a bottle forming tool of the order stated, the bolt or pin F provided
with means for adjusting the throw of the bit C, substantially as, and for the
purpose, set forth.
Fifth. The jaws A, plug B and bit C, in combination with the bar E formed with
shoulders J, substantially as, and for the purpose, set forth.
