ealed the 18th February 1876, and dated the 22nd December 1875.
COMPLETE SPECIFICATION filed by the said Alexander Melville
Clark at the Office of the Commissioners of Patents, with his
Petition and Declaration, on the 22nd December 1875, pursuant to
the 9th Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex;

page_text: Stopper D is made of rubber or other elastic material with a disc-shaped
base and central shank or stem, which is perforated near the upper end
to be readily placed on the yoke C, and swung into any position thereon.
A metallic cap piece E with sleeve-shaped lower part and top flange is
5 placed around the shank of the stopper D below the yoke passing
through the shank, and serves to press into the disc part of the stopper
when the lever frame and yoke are swung downward on the bottle
closing by the convex shape imparted to the stopper base, thereby
securely and tightly closing the mouth of the bottle, as shown in
0 Figure 2. The upper part of the cap piece E is provided at both sides.
of the end or head of the stopper shank, and preferably at right angles
to the yoke, passing through the same with projecting guard lugs d of
equal or slightly greater height with the head of the shank that projects
above the top of the cap piece, so that the end of the shank cannot
o be injured during transportation or use by heavier bodies coming in
contact therewith. The closing of the stopper is performed by guiding
the base part into position on the mouth, and swinging the lever frame
down until seated on the neck of the bottle. The stopper is applied so
firmly to the mouth of the bottle that no accidental detachment in
O handling, shipping, &c., is possible. It has no projecting parts, is
quickly opened and closed, and can be manufactured at as cheap rates
as other bottle closing devices at present in the market.
Having described the nature of the Invention, and the manner of
performing the same, I declare that what I claim as new and desire to
5 secure by Letters Patent is,-
1st. The bottle stopper device composed of a pivoted lever frame
applied to the neck of the bottle with eccentrically hinged yoke carrying
the elastic stopper and cap piece, arranged and operated substantially as
specified.
) 2nd. The elastic stopper hung by its perforated stem or shank to the
upper part of the hinged yoke in combination with the yoke and a
sleeve-shaped cap piece placed over the stopper below the yoke, sub-
stantially as specified.
3rd. In bottle closing devices an elastic stopper made of a disc-
5 shaped base part and central stem or shank perforated near the upper
end for the purpose set forth.

page_text: 4th. In bottle stoppers a flanged and sleeve-shaped cap piece provided
with projecting top guard lugs at both sides of the projecting head or
end of the shank of the stopper, substantially as specified."
In witness whercof, I, the said Alexander Melville Clark, have
hereunto set my hand and seal, this Twenty-second day of 5
December, in the year of our Lord One thousand eight hundred
and seventy-five.
