Charles G. Hutchinson Bottle Stopper
UNITED STATES PATENT OFFICE
CHARLES G. HUTCHINSON, OF
IMPROVEMENT IN BOTTLE-STOPPERS.
Specification forming part of Letters Patent No. 225,476,
dated March 16, 1880; application filed December 8, 1879.
To all whom it may concern:
Be it known that I, CHARLES G. HUTCHINSON, of
In the drawings, Figure 1 is a vertical central section of the upper part or neck of a bottle, showing a side view therein of a stopper embodying my invention and in position for closing the neck; and Fig. 2 is a like representation, excepting that it shows an edge view of the stopper in position for leaving the neck open.
Like letters of reference indicate like parts.
My invention relates to that class of bottle-stoppers provided with a laterally-yielding spring extending upward from the plug, and adapted to hold the latter in its open and closed position, alternately, according to the adjustment vertically of the spring in the neck of the bottle.
A represents the neck of a bottle. B is a rubber disk confined between two metallic disks, C and D, the latter or lower one of which is larger than the other metallic disk, but not so large as the disk B, as shown.
The disks C and D are connected to each other centrally by a neck passing centrally through the disk B, or by means of a wire, to which the metallic disks may be either molded or otherwise attached; but I have not here shown in detail the manner of connecting the said disks, as the construction, relative arrangement, and mode of connection are old and well known, and form no part of my present invention, excepting as connected with the features of construction relating to the remaining parts of the stopper, and hereinafter specifically set forth, my object in referring to these disks as particularly as I have now done being to distinguish valves of this class to which my invention is applicable from others, such as tapering plugs adapted to sustain themselves with certainty in the neck, so as to close it effectually even when the contents of the bottle are not effervescent.
E is an elongated eye or loop applied to the metallic disks above referred to, and arranged transversely with relation to them, and so as to project into the neck, as clearly shown in Fig. 1. I make the eye or loop E of wire.
F is a spring-wire centrally bent upon itself, as shown, and the lower parts or ends of which stand apart from each other a distance about equal to the length of the loop E, and which ends are bent around the cross-bar of the said loop so as to inclose (sic) the same loosely enough to allow the said ends to move freely back and forth on the said bar without danger of being detached therefrom.
The loop formed by the spring F is centrally contracted, so that it conforms to the contracted part of the neck of the bottle to a greater or less extent.
It will be perceived, from the foregoing description and from reference to the drawings, that an upper and lower enlargement are thus formed in the spring or loop F, and that the upper enlargement will suspend the spring and disk B in an open position, and that the lower enlargement will then hold the said disk approximately in a central position below the neck, and also suspend and hold the said disk in its closed position when the said spring or loop is drawn up into the position shown in Fig. 1, it being understood that the spring F, by being connected to the loop or eye E in the manner shown and described, is capable of lateral contraction and expansion while being moved up and down in the neck for the purpose of closing and opening the bottle.
It will also be perceived that both the lower ends of the spring or loop F may move laterally on the cross-bar of the lop or eye E, the said bar being long enough to admit of this movement and of the expansion of the lower enlarged part of the spring or loop F against the interior of the neck, as and for the purposes described, but not too long to allow the disk B to be raised to its closed position.
It will also be perceived that the upper enlargement of the spring or loop F enters the neck of the bottle when the disk B is in its open position, and that the lower enlargement is in the neck when the said disk is in its closed position, and that the said disk is at all times held in its various positions by means of the lateral expansion of the spring or loop F against the interior of the neck.
I am aware that a bail having an enlargement at its upper end sufficiently great not to enter the neck of the bottle has heretofore been combined with a tapering plug adapted to hold itself in its closed position in the upper part of the neck, and at such a height therein as to permit the said bail to be then laid horizontally outside of the neck, the said enlargement, by resting on the upper end of the neck, performing the function of suspending the said plug with certainty in its open position, and the remaining part of the bail being broad enough to hold the plug in, or nearly in, a central position with relation to the neck when so suspended, and I do not, therefore, here intend to claim such.
I am also aware that internal bottle-stoppers have heretofore been so constructed as to be held, by various other means, either in their open or closed position; but, with the exceptions hereinafter stated, I am not aware that internal bottle-stoppers have heretofore been so constructed as to be held automatically both in their open and closed position alternately by means of a laterally expanding and contracting spring loop applied to a flat or disk-shaped valve.
The exceptions above referred to are shown and described in Letters Patent of the United States of America issued to me for improvements in bottle-stoppers, and numbered 213,992, dated April 8, 1879, and reissued June 17, 1879, the reissue number being 8,755, and No. 219,729, dated September 16, 1879, and I do not here intend to claim any of the said improvements.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is –
The flat or disk-shaped valve B, the laterally-elongated eye D, and the centrally-contracted spring-loop F, having an open lower end and upper and lower enlargements, both adapted to enter the neck of a bottle, and both lower ends of the wire of the said loop having therein eyes or openings for freely receiving and suspending the cross-bar of the eye E, all combined and constituting an internal bottle-stopper adapted to be held both in its open and closed positions alternately by means of the said loop, substantially as specified.
