Improvements OC StoppeID.
I, DAVID ERASTUS CORNING, of Number 230 West Genesee Street, in the Town
of Auburn, County of Cayuga, and State of New York, United States of America,
Gentleman, a citizen of the United States, 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 improvements in bottle stoppers and it consists of a
detachable bottle stopper adapted to keep the bottle tight and to keep any foreign
matter from getting into the bottle, and also to obtain a flow from the bottle
through the stopper that may be regulated as desired.
The said invention will be understood by reference to the accompanying drawings
in which the same parts are indicated by the same letters throughout the several
views.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents a central vertical section through the neck of a bottle fitted
with one of my improved stoppers.
Fig. 2 represents a side elevation of the device shewn in Fig. 1, the bottle being
in position for pouring out its contents.
Fig. 3 represents a perspective view of the plunger used in the device shewn in
Figs. 1 and 2.
Fig. 4 represents a similar section to that shewn in Fig. 1, with a modified form
of my improved stopper.
Fig. 5 represents a similar view to that shewn in Fig. 2 showing the stopper
used in Fig. 4.
Fig. 6 represents a perspective view of the plunger used in the device shewn in
Figs. 4 and 5.
Fig. 7 represents a similar view to that shewn in Figs. 1 and 4 with a modified
form of stopper, and
Fig. 8 represents a side elevation of the plunger shewn in Fig. 7 as detached
from the other parts of the stopper.
A represents the bottle which may be of any well known or desired form.
B represents a metallic casing, which is preferably cylindrical in form, but may be
of any other shape desired, and is provided with an annular shoulder b beneath
which the annulus C of cork, rubber, leather, or other similar material is mounted
over the base of the casing.
This annulus is preferably made tapering so as to fit snugly in the neck of the
bottle as shewn in Figs. 1, 4 and 7.
The stopper is completed with the addition of a plunger which is adapted to
move in and out of the casing B, as will be hereinafter described.
In Figs. 1 to 3, the plunger D is provided with shoulders d adapted to fit snugly on
the top of the casing B, and is provided with slots d¹ terminating in stops d²
preferably formed out of the body of the plunger.
The number of the slots d¹ may be varied at will, and in one or more of these
slots a pin is caused to project from the casing B, as shewn in Figs. 1 and 2.
The orifice formed by the opening of the slots beyond the face of the casing B

page_text: may be varied either by making the slots d' shorter, or by varying thể positions of
the pin as indicated by the dotted lines at 6 in Figs. 2 and 7:
With the form of device shewn in Figs. 1 to 3 the bottle is not intended for
transportation with my improved stopper mounted therein, but suitable stoppers
must be provided for purposes of transportation, while the hereindescribed stopper
is well adapted for keeping flies, dust and other impurities out of the bottle and at
the same time enabling the contents of the same to be poured out without
undergoing the troublesome process of uncorking the bottle.
In the form of device shewn in Figs. 4, 5 and 6, the plunger D¹ is provided with
a milled head as beneath which a rubber or like gasket E is placed.
The slot d of the said plunger is provided with a lateral slot do having cam
surfaces d' and d' adapted to engage the pin & passing through the casing B.
These cam surfaces are set at an incline and are so arranged that when the
plunger D is down in the casing B, a twist of the milled head in one direction
will cam the plunger down tight on the gasket E, and thus firmly and securely
close the bottle, while a siniple twist in the opposite direction will open the
bottle.
With stoppers of this class the bottle may be transported without danger to
its contents, and at the same time it may be readily opened and closed whenever
desired.
In' the form of device shewn in Figs. 7 and 8, a screw-thread d is provided ou
the plunger which engages in a corresponding female screwthread 60 in the
casing B.
These screwthreads are so arranged that a partial turn of the miilled
head do will set the plunger down firmly on the gasket E.
In this form of device the plunger D has wide slots to enable the pin to
have the requisite motion therein, so that the screwthreads may be caused to
engage each other.
This form of stopper is also adapted for transportation while placed in the bottle
without danger of leakage theré-througli.
In these various forms of device, the opening through the plunger for the passage
of the liquid may be regulated either by adjusting the lengths of the slots in the
plunger, or by changing the position of the holding pin or pins b¹.
While I have shewn two pins in Fig. 1 and oppositely disposed slots in the other
figures, it will be obvious that but one pin and one slot would be all that would be
required, or only one pin need be used with a number of slots.
But by having the slots oppositely disposed air will come into one slot while the
fluid is flowing out of the other and thus the bottle will pour readily.
It will be seen that the bereindescribed stopper may be readily so arranged as to
pour an exceedingly fine stream and thus it is eminently adapted for use in drug
stores, laboratories and other like places, where frequent and exact measurements
of liquids are desired.
It will also be seen that the hereindescribed stopper provides a neat, simple, and
effective means for closing the mouths of bottles which inay be readily adjusted to
pour from the bottle and as readily adjusted to close the same, to the exclusion of
air, dust, flies, and other foreign particles:
The hereindescribed stopper is shewn cylindrical, as of the simplest form but the
same idea may be applied to other bottle stoppers of various shapes.
These and the various other advantages of the hereindescribed construction will
readily suggest themselves to any practical mind.
Various modifications of the hereindescribed invention might be made that could
be used without departing from the spirit of my invention.
Having thus particularly ascertained and described the nature of my said
invention, I declare that what I claim is :-
1. In a bottle stopper, the combination with a casing provided with a packing
ring exterior thereto, and adapted to engage in the neck of the bottle, of a slotted
plunger adapted to move longitudinally in said casing and to rest on the top thereof

page_text: when the bottle is in an approximately vertical position, and a pin projecting from
said casing into one of said slots and adapted to limit the outward travel of said
plunger, substantially as and for the purposes described.
2. In a bottle stopper, the combination with a casing provided with a packing
ring exterior thereto and adapted to engage in the neck of the bottle, of a slotted
plunger adapted to move longitudinally in said casing, a gasket placed beneath the
top of said plunger and interposed between it and the top of said casing, means for
locking said plunger down on said casing, and a pin projecting from said casing
into one of said slots, and adapted to limit the outward travel of said plunger,.
substantially as and for the purposes described.
3. In a bottle stopper, the combination with a casing adapted to engage in the
neck of the bottle, of a plunger mounted in said casing and provided with a
longitudinal slot and a cam groove at one side of said slot, and a pin projecting
from said casing into said slot and adapted to engage in said cam groove and to lock
said plunger, substantially as and for the purposes described.
4. The construction, combination, and arrangement of parts substantially as
hereindescribed and shewn in Figs. 1, 2 and 3 of the drawings.
5. The construction, combination, and arrangement of parts, substantially as
hereindescribed and shewn in Figs. 4, 5 and 6 of the drawings.
6. The construction, combination, and arrangement of parts substantially as
hereindescribed and shewn in Figs. 7 and 8 of the drawings.
