IMPROVEMENTS IN BOTTLE STOPPERS
Year: 1885

page_text: İ, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN BOTTLE STOPPERS" (a communication to me from abroad by William Stewart of
Brooklyn in the County of Kings and State of New York United States of
America) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
The object of this invention is to provide bottle stoppers constructed in such a
manner that they will allow the bottles to be readily filled and emptied, will close
the bottles securely and will be inexpensive in manufacture.
The invention relates to a bottle stopper constructed with a tubular packing
having a flanged outer end, and a beveled inner end to serve as a seat for a ball
float placed within the bottle, the said packing being secured in place in the mouth
of the bottle by an annular cup having arms and secured to the bottle by a wire
passing around the neck of the bottle, and the said arms as will be hereinafter fully
described and then claimed.
Reference is to be had to the accompanying drawings forming part of this
specification in which similar letters of reference indicate corresponding parts in all
the figures.
Figure 1 is a side elevation of one of the improved bottle stoppers shown as
applied to a bottle.-Figure 2 is a sectional side elevation of the same taken
through the line x, x, figure 1. Figure 3 is a plan view of the same.
A represents an ordinary bottle into the mouth of which is fitted a tubular
packing or bushing B having around its upper end a flange to rest upon the edge
of the mouth of the bottle, as shown in figures 1 and 2. The inner surface of the
inner end of the packing B is flared or beveled to form a seat for the ball C placed
within the bottle A. The ball C can be made of hard rubber or other suitable
material that will not corrode or be affected by moisture or acids, or is plated with
a noncorrosive metal. The ball C must be of such a buoyancy that it will readily
float upon the liquid contained in the bottle.

page_text: The packing B is held from being forced out of place by outward pressure from
the contents of the bottle by an annular, cap D placed upon the flanged outer end
of the packing B and having three, more or less, arms E formed upon or attached
to its outer edge. The arms E are so formed or bent as to extend along the neck
of the bottle and are secured to the said neck by a wire F passed around the said
arms and neck and around which the ends of the said arms are bent as shown in
figures 1 and 2.
The improvement is designed to be used in bottling soda water and other liquids
generating gases and thus producing an outward pressure.
In using the improvement the ball C is placed in the bottle and the packing B is
inserted in the mouth of the said bottle and secured in place by the cap D, E and
the wire F.
Then as the bottle is filled the ball Crises with the liquid until it comes to its
seat in the lower end of the packing B where it is held in place by the outward
pressure of the contents of the bottle.
When the bottle is to be emptied, it is held in a horizontal, or inclined position
and the ball C is pushed from its seat by means of a rod or other suitable
implement and at once rises through the liquid to the highest part of said bottle
and thus allows the contents of the bottle to flow out freely.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
The herein described bottle stopper consisting of the tubular packing B provided
with a flanged outer end and having the inner surface of its inner end bevelled and
flared the ball float C the fastening wire F the metal cap D provided with the
arms E adapted to have their ends bent around the said fastening wire as set
forth.
