IMPROVEMENTS IN
FREDERICK HALL of Sheffield in the county of York
PROTECTIVE COVERINGS FOR BOTTLES (SUCH AS DRINKING FLASKS) AND IN THE
MOUTH PIECES OF SAME
My invention relates to improvements in removable protective coverings for bottles
and inore particularly to removable coverings for drinking flasks and to the mouth-
pieces for such flasks, the object being to combine the cleanliness of a glass bottle,
with the handsome appearance, and strength of a metallic flask, as well as to enablo
a broken glass to be easily replaced without unsoldering or undergoing any other
process requiring skill; and also to enable the bottle to be quickly taken out of the
cover, washed, and replaced.
This I accomplish by casting, stamping or otherwise forming the removeable
cover in two or more parts from any suitable material or metal, but by preference
of metal; the body of the cover being made in two halves, the division being
longitudinally through the neck and edges as being the most convenient shape for
manufacture. The two parts are joined together either at the bottom or at the
side, as may be preferred by a hinge or its equivalent, and the neck is provided
with a screw throad for the cap or stopper to be screwed upon.
When the metallic cover is closed, a ring provided with a thread, corresponding
to that on the neck, is screwed tightly down to the body of the cover, the parts
being thus held firmly and securely together. I form the mouthpiece of the glass
bottle longer than usual, so that a portion shall extend beyond the metal screw,
this projecting portion is by preference tapered, forming a coned mouthpiece which
is more convenient and agreable to drink from than the sorewed end of an
ordinary flask.

page_text: For securing the mouths of bottles intended to contain liquids that would lose
their strength by evaporation (or other liquids) and to better protect the contents
from loss in transit and from other causes, I construct a cap and stopper in the
following manner, and I apply the same to bottles with or without the cone shaped
mouthpiece as before described. I form the cap with an internal screw-thread to
fit upon a corresponding screw formed either upon the glass neck, itself or upon a
metallic collar which may be attached to the neck of the bottle; a layer of cork or
other elastic material being placed in the head of the cap in the usual manner.
This Elastic material is intended to press upon the head of a glass stopper which
fits into the mouth of the bottle; and an elastic ring or washer under the head of
the stopper is also pressed against the lip of the bottle, when the cap is screwed
tightly down, thus effectually closing the mouth, and preventing any escape of the
contents.

FREDERICK HALL of Sheffield in the County of York, "IMPROVEMENTS IN
PROTECTIVE COVERINGS FOR BOTTLES (SUCH AS DRINKING FLASKS) AND IN THE
MOUTHPIECES OF SAME
"
My Invention relates to improvements in removeable protective coverings for
bottles, and more particularly to removeable coverings for the bottles of drinking
flasks, and also to the construction of the mouthpieces of drinking flasks, the object
of the invention being to combine the strength of the metallic cover, with the
cleanliness of the glass bottle, and to easily replace an accidentally broken bottle,
without having to unsolder any of the parts, also to enable the glass bottle to be
readily taken out of the metallic cover or case, and replaced after being washed,
and with reference to the mouthpieces of flasks, the object is to provide a more
convenient and pleasant mouthpiece to drink from than those of flasks made in the
usual manner.
•
In order that my invention may be clearly and fully understood I shall refer
from time to time to the drawings accompanying this Specification, first premising
that the same letters of reference indicate the same parts in all the figures.
Fig. 1, represents the edge view of a drinking flask with the case or cover
open, A being the glass bottle, B and C the sides of the case, D the hinge, I the
projecting neck of the bottle.
Fig. 2, is a front view with the case open, and partly in section.
Fig. 3, represents the closed flask complete.
Fig. 4, represents a closed flask with hinge at the side, the cap G being removed
to show the projecting neck of the bottle.
In carrying out my invention as applied to a drinking flask (for example) I cast,
stamp, press or otherwise form metal or other suitable material into the desired
shape or design of the case or cover; the body of the said case or cover being made
in two principal parts or halves marked B and C in figure 1, on the sheet of
Drawings
I prefer to make the division of the parts longitudinal, through the edges
and neck of the case or cover as being the most convenient arrangement for
manufacture.
The two parts are joined together at D by a hingo or its equivalent contrivance,
but I do not bind myself to the position of the hinge, as it may be placed at the
side, as shown in Fig 4, instead of at the bottom as shown in Fig. 1. The neck of
the case or cover E is screwthreaded, and the two parts are secured by a corre-
spondingly threaded ring F which is screwed down to the shoulder of the body of
the case or cover, leaving sufficient of the threaded portion of the neck for the
cap G to be screwed upon, but other means of securing the two parts together may
be used.
The glass neck of the bottle A, marked I in Fig. 1 is made to project from the
metal neck of the case or cover, thus forming a glass mouthpiece which is much
more agreable to the mouth than the screwed metallic end of an ordinary flask.
In some cases, for greater security in preventing the escape of the contents, I use
a glass stopper fitting into the neck I of the bottle A, provided with a head H,
under which may be placed a ring or washer of elastic material, the cap G is
provided with au internal cushion of cork or other elastic substance so that it shall
slightly press upon the top of the head of the stopper H.

page_text: The protective case or cover as hereinbefore described may be used in com-
bination with bottles having the elongated neck, to form a mouthpiece, or to
bottles not having elongated necks, and with or without the glass stopper.
Having now described and fully ascertained the nature of my said invention, and
the manner in which it is or may be carried into practice, I wish it to be understood
that I do not confine my invention to any particular design or configuration of
case, nor to its application to drinking flasks alone, but what I consider to be
novel and original and therefore claim as the invention secured to me by the
herein before in part recited Letters Patent, is :—
First, The manufacture of removeable protective coverings or cases for bottles;
provided with hinges, or their equivalents, so that the cases may be opened,
and the bottles readily taken out and replaced substantially as described and
illustrated.
Second, The construction of the mouthpieces of drinking flasks, by making
the glass neck of the enclosed bottle to project sufficiently beyond the screwed
neck of the case or cover so as to form a mouthpiece which may be closed by
a glass stopper, secured by a cap, or by an ordinary cap with an elastic pad,
substantially as described and illustrated.
Third, The manufacture of drinking flasks, having removeable cases or covers
made of any suitable metal or material, made in two principal parts, sub-
stantially as hereinbefore described and as illustrated in the annexed sheet of
drawings.
In Witness whereof I the said Frederick Hall, have hereunto set my hand and
seal, this twenty seventh day of September, in the year of our Lord one thousand
eight hundred and eighty three
