PROVISIONAL SPECIFICATION left by the said Thomas Leeming and Richard
Ray at the Office of the Commissioners of Patents on the 29th April 1879.
THOMAS LEEMING and RICHARD RAY, both of Manchester, in the County of
Lancaster, Lithographers. "AN IMPROVED TAP FOR STEAM, WATER, OR OTHER
FLUID."
Our Invention consists of a tap or cock, the seating and valve of which are
composed of glass, metal, or other suitablo material.
In performing our Invention we make use of a circular or other shaped plate of
glass. or other material having a hole at or near the centre, which plate may be
fixed in a recess above the nozzle or mouth of the tap by the nozzle which is
screwed into the socket or body of the tap. Between the plate and nozzle we place
a washer of india rubber or other suitablo material to make a water tight joint;
above the plate is another recess or box containing the valve, which valve we make
of a flat, circular, or other shaped piece of glass or other material larger than the
hole in the plate before mentioned, which valve covers the hole and makes a
perfectly tight joint.
To open the valve we make use of a lever, trigger, or other contrivance, one end
of which passes through the hole in the plate and raises the valve; this trigger may
be actuated by a screw or handle.

the said Thomas Leeming and Richard Ray in the Great Seal Patent Office
on the 29th October 1879.
THOMAS LEEMING and RICHARD RAY, both of Manchester, in the County of
Lancaster, Lithographers. "AN IMPROVED TAP FOR STEAM, WATER, OR OTHER
FLUID."
Our Invention consists of a tap or cock, the seating and valve of which are
composed of glass, metal, or other suitable material. In performing our Invention
we make use of a circular or other shaped plate of glass or other material having a
hole at or near the centre, which plate may be fixed in a recess above the nozzle or
mouth of the tap by the nozzle which is screwed into the socket or body of the tap
or otherwise. Between the plate and nozzle we place a washer of india rubber or
other suitable material to make a water tight joint. Above the plate is another
recess or box containing the valve, which valve we make of a flat, circular, or other
shaped piece of glass or other material larger than the hole in the plate before
mentioned, which valve covers the hole and makes a perfectly tight joint. To open
the valve we make use of a lever, trigger, or other contrivance, one end of which
passes through the hole in the plate and raises the valve; this trigger may be
actuated by a screw or handle.
And in order that our Invention may be fully understood and readily carried
into effect we will proceed to describe the accompanying Sheet of Drawings.
Fig. 1 is a section of a water tap to which our improvements are applied; Fig. 2
is a section of part of a cistern to which our improvements are applied; and Fig. 3
shews a plan and an edge view of our improved valve and seating. In Fig. 1 a is
the body of the tap; b is our improved seating made of glass or other material
having a hole at its centre covered by the valve c, also made of glass or other
material, which, when the tap is closed, rests upon the seating, as shewn in the
Drawing; d is a lever or trigger, one end of which passes through the hole in the
seating 6 in order to open the valve c when desired; the dotted lines shew the
positions of the lever or trigger and the valve when the water or other fluid is
flowing; e is a screw for actuating the lever d; when the screw is in the valve is
closed, and when it is screwed outwards, as shewn in dotted lines, it opens the
valve.
In Fig. 2 is the body of a cistern; b is the valve seating; c is the valve; and
is the rod which opens and closes the valve by means of a lever and handle or
other connection; it acts substantially the same as the valve shewn in Fig. 1.
We prefer to make our improved valve of a square or oblong shaped piece of
glass with the edges bevelled, as shewn in Fig. 3.
Having thus stated the nature of our Invention, and described the manner of
performing the same, we wish it to be understood that we do not limit ourselves to
the details given as the same may be considerably varied or modified, but what we
claim is, the tap or valve composed of two plates or discs of glass or other similar
material, one plate forming the seating and having a hole for the fluid to flow
through, and the other plate forming the valve, substantially as shewn and
described.
In witness whereof, we, the said Thomas Leeming and Richard Ray, have
hereunto set our hands and seals, this Twenty eighth day of October, One
