PROVISIONAL SPECIFICATION left by Charles François Cattaert at the
Office of the Commissioners of Patents, with his Petition, on the 24th
July 1856.
I, CHARLES FRANÇOIS CATTAERT, Merchant, of Paris, in the French Empire,
do hereby, declare the nature of the said Invention for "IMPROVEMENTS IN THE
STOPPERING OF INKSTANDS, BOTTLES, POTS, JARS, AND OTHER VESSELS, AND CLOSING
Cocks," to be as follows:-
My improvements in stoppering bottles, jars, and other vessels or receptacles,
consist in the employment of a flat or other surface of glass, which, in order to
close the bottle or vessel, is brought over the mouth or on the top thereof,
which is ground true or otherwise formed so that the glass surface may lie
accurately upon it, and entirely close the opening. The glass surface is kept
firmly pressed on the top edge of the bottle or vessel, by means of a spring
placed behind or on the top of the glass, or by a cap or otherwise, or the glass
surface (provided with a spring or not) may be fitted in a cap, cover, or lid,
hinged or otherwise connected to the bottle or vessel, or to the case containing
it, or separate therefrom, so that on shutting down the cover or fixing it on the
bottle, the glass surface is brought over the mouth of the bottle and closes it.
To close the fluid way of taps and cocks I fit a screw plug into the body of
the tap, having at bottom or on its inner end a piece of glass, which, when the
plug is screwed down, lies flat on the top of another piece of glass, which is

page_text: fixed in a suitable position in the body or fluid way of the tap, and which has
an orifice in its centre for the passage of the fluid. The surfaces in contact of
the two pieces of glass must be ground true, so that when together one may
lie closely upon the other. The screw plug is worked by a handle from the
outside, and when it is desired to close the fluid way the plug is turned until
the glass at bottom is brought up against or on the glass fixed in the tap,
thereby covering over the central orifice and closing the fluid way.
My improvements in closing taps also consist in the employment of a glass
plug, or conical glass ring fitted round a plug, the surface of the glass being
turned true, to fit into a conical glass seat or ring fixed in the body or fluid way.
The glass plug is worked by a handle, on the surface of which, inside the tap, a
smaller roller or boss is mounted excentrically, which, on turning the handle to
open the tap, comes against a roller fixed on a pin at the end of the rod of the
plug, forces the plug down out of its seat, and opens the fluid way. To close
the tap, the handle is turned in a reverse direction, which brings the roller on
it clear of the roller on the rod of the plug, which is forced back into its seat
by a spring fitted in the body of the tap, in such a position as to press against
the bottom or broad end of the conical plug. By mounting two rollers
excentrically on the handle, two glass plugs may be worked in a two-way tap
by one handle. The plug and its seat by be cylindrical instead of conical.
