An Improved Implement or Tool for Forming or Shaping the Necks
of Bottles.
1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 :-
This invention relates to hand-tools for forming or shaping the necks of glass
bottles, and more particularly to tools, which operate to form an annular shoulder
on the exterior of the bottle neck for the retention of a metal sealing cap
thereon.
The jaws of the improved tool are hollowed out to cause them to fit more closely
to the bottle-neck and thus to have greater bearing surface, whereby the rapid
wear thereof is obviated. It is clear that if the jaws wear away rapidly as is the
case with such tools having flat jaws they will not form the annular shoulders on
the bottle necks of a uniform size, that is to say, the shoulders of the bottles made
when the tool is worn will be slightly larger than those of the bottles made when
the tool is new, consequently the metal caps for sealing the bottles will not
properly fit the shoulders of the last named bottles and defective sealing would be
the result.
By the present invention this objection is to a great extent obviated.
In the accompanying drawings,
Figure 1 is a side elevation of my improved tool for shaping the necks of bottles
and for forming the annular shoulder thereon.
Figure 2 is a transverse section of one of the jaws, on the line X, X of
Figure 1.
A, A are the two jaws which are hinged at B, and which are preferably of
chilled cast iron. C is the spring which tends to keep the jaws apart, in the position
shown in Figure 1. D is the central spindle or rod preferably of wrought iron
movably held in a socket at the base of one of the jaws as heretofore. E, E are
two levers pivotted at E', E', to the jaws A, A and at E, E to the cross-piece D¹
on the central rod D. The said levers serve to keep the rod D central between
the jaws and also render the whole tool very rigid laterally. The part D² of the
rod D serves as a stop to limit the inward travel of the jaws. D³ is the plug that
enters the bottle neck and determines the internal diameter thereof. This plug is
preferably made of chilled cast iron and is secured to the rod D in any suitable
manner.
The grooves A¹, A' in the jaws A, A serve to form the annular shoulder on the
bottle-neck for the purpose above mentioned.
Figure 2 shows at A the manner in which the jaws are hollowed out in my
improved tool. By hollowing the jaws in this manner I provide a new tool
which has jaws similar to the worn jaws of an old tool made as heretofore.
Such jaws will have a comparatively wide bearing on the bottle neck instead of
the narrow bearing of the jaws made as heretofore, and consequently rapid wear of
the jaws will, as before stated, be largely obviated, with the result of ensuring
uniformity in the shape and size of the bottle necks produced.

page_text: The prolongation A3 of the jaws beyond the hollow part above referred to may
be long or short according to the shape of the bottle neck. In some instances
instead of the non-rotating prolongations A³ shown in the drawings I may provide
rollers to work by rolling contact with the bottle neck.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is:
1. A tool, such as that herein described, having jaws hollowed out as shown in
Figure 2, for the purpose specified.
2. A tool having the jaws and plug formed of cast and chilled iron, the former
being hollowed out as shown and described with reference to the accompanying
drawings, for the purpose specified.
Dated this 18th day of September 1894.
