Improvements in Taps or Cocks.
I, CAMILLE MEYER, of 1, Avenue de la République, Esbly, near Melun, Seine
and Marne, France, Engineer, 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:-
1
This invention relates to improvements in taps or cocks and has for its object
to provide a tap, the spigot of which is disengaged from the body of the tap in
the act of opening the same, thus preventing its jamming, and at the same time
rendering the tap perfectly staunch or tight.
The improved tap or cock may be used for water, steam, compressed air, or
other liquids or gases.
In the accompanying drawing one form of construction of my invention is
illustrated.
6 represents the stem or body of the tap, in which a plug c is arranged so as to
turn freely. Above its conical part, the said plug is provided with a shoulder
upon which rests a tightening washer of suitable material, for example of a
soft alloy specially fit for the purpose.
This washer is compressed or squeezed by screwing home the collar g upon the
top of the body b.
The handle is made flush upon and completely coincides with the collar g by
means of a nut e and its washer, screwed on the end of the plug spindle. This
latter when set in, closes the tap as represented in the drawing, the handle taking
in this case the position p shewn by a dotted circle.
The tap is opened by turning the plug a quarter. turn, thus causing the handle
to take the position p..
By this movement the collar g is raised to a height corresponding to a quarter
of the pitch of the screw and the plug completely coinciding with the collar by
the pressure of the handle and by means of the nut e, will also be raised to a corre-
sponding height, thus raising it from the seating.
The tightening washer r is always subjected to the same pressure and conse-
quently will always form a tight joint whether the tap is opened or closed.
In the closed position the plug is tight on its seating, because of its conical
part being caused to descend to an extent corresponding to a quarter of the pitch
of the collar-screw g into the conical seating in the body of the tap, thus forming
the tight connection, as at first determined when the plug is in its closed position.
The advantages of the improved tap resulting from its plug being raised during
the act of opening are as follows:
No jamming of the plug, no difficulties whatever in the acts of opening and
closing, an easy and quick operation, and perfect tightness being concurrently
maintained.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:--
1. The improved tap or cock, substantially as described and illustrated in the
accompanying drawing.

page_text: 2. A tap or cock, the main feature of which consists in the plug being raised
from the seating by the act of opening the same, effected by means of a collar
screw being screwed home to the body of the tap and rendered flush upon the
plug spindle, and by squeezing a tightening washer, substantially as described
and represented in the drawing.
3. A tap, in which the plug is raised or disengaged from its seating by the
opening operation of the handle fixed flush upon the said plug spindle, by means
of a collar screwed home to the body of the tap and a tightening washer com-
pressed by this collar, substantially as set forth and shewn in the accompanying
drawing.
4. A tap, the main feature of which consists in the plug being raised or dis-
engaged from its seating in the body of the tap by unscrewing the collar, and by
compressing a tightening washer in screwing home the said collar upon the plug
spindle, substantially as set forth and shewn in the accompanying drawing.
Dated this 27th day of November 1899.
