On 27th April 1881, describing himself as a valve engineer, he submitted another valve related patent application – No. 1881/1816 entitled “Improvements in Valves and Taps for Hot and Cold Water, Gas, Steam and other Liquids and Fluids”. Here he was on familiar ground and the patent was sealed on 27th October, 1881. The invention was described as follows:-
My improvements consist in the first place in forming a valve or tap body made of brass, iron, or other suitable material in the well-known usual form, or modified to suit the numerous purposes for which valves or taps are used, in the interior of which I place a partition with an aperture through same of the desired size perpendicularly, horizontally, or at an angle of 45° or other desired degree. Upon this partition I place a valve seating of india rubber, cork, felt, metal, or other desired material or combination of materials, having through it or them a conical or rather shaped aperture, the smaller end of same resting upon the before named partition.
Secondly. I construct a loose ring of brass, iron, or other suitable material, and f ix upon the upper side of valve seating, with an aperture through same somewhat larger than the upper or large conical end of valve seating, which ring is secured in place by metal bars projecting from valve or tap cover or their equivalent; these metal bars also ensure cone (afterwards described) being kept in its proper position.
Thirdly. I construct a cone or other shaped metal plug or valve of suitable size and shape to fit (when forced into position) the above named seating. Upon this plug I form a projection or shoulder, which is made to press upon the loose ring, and by this means press the flexible seating in a lateral direction tightly upon the cone or other shaped plug, thus making it water or fluid tight. The plug is kept in position and not allowed to turn around by forming two or more slots in shoulders of same, and fitting them to before named metal bars, upon which the plugs moves freely or by an equivalent device.
Fourthly. To raise or lower the moveable cone plug I form an internal screw in same, and with a corresponding external screw on a spindle fitted with handle, wheel, or other appliance, or an internal screw may be formed through a boss or other arrangements forming on spindle to work the same, and thus operate upon moveable plug. When the plug is operated upon by this means of pins, flanges, or their equivalent, so as to revolve freely in same by means of pins, flanges, or their equivalent, so as to lift the plug out of seating or force it into same; or I sometimes operate upon plug by means of a lever, bevel wheels, gearing, quadrant, worm float ball, or other appliance suited to the situation or purpose for which valve or tap is required. The spindle or worm rod is made to work through a gland attached to valve or tap in the well known usual way.
When the patent came up for renewal on 27th April 1885, Thomas Messenger duly paid the £50 stamp duty and renewed the patent.
