IMPROVEMENTS IN TAPS FOR WATER STEAM AND GAS
Year: 1884

page_text: I THOMAS SINGLETON of Bank Top Machine Works Over Darwen in the
county of Lancaster Machine Maker do hereby declare the nature of my Invention
for "IMPROVEMENTS IN TAPS FOR WATER STEAM AND GAS," to be as follows:-
I make the outer casing of the tap as ordinary, also the plug, but this contains
an inner plug, when turning the tap partly on, so as to regulate the supply, instead
of turning the plug proper, I turn the inner plug, by this means the surface of the
outer plug is not exposed to the action of the steam and water.
In gas taps I construct the internal plugs as usual, but the holo for the passage
of gas is bored conical, and is smaller at the side for admitting gas, on turning the
gas partly on the gas does not deviate in its course, but takes a direct line of
passage or instead of the above the inner plug may pass up the inside of the plug
proper and when turning the gas partly on to regulate it, I turn the inner plug or
screw, reducing the opening, but still not deranging the straight course of the gas;
another advantage this construction of gas tap has, is that when an ordinary gas
tap is turned partly on if the plug is slack the pressure of the gas acting upon the
angle of the hole in the plug will at times turn on the gas, but by using the above
arrangement this cannot possibly occur.

Fig 2 is a sectional plan of Fig 1.
Fig 3 is an elevation in section of tap for gas.
Fig 4 is a sectional plan of Fig 3.
Fig 5, is a sectional clevation of gas-tap-with-regulating screw.
A is the outer casing of tap constructed as ordinary, B is the plug which
contains an inner plug C, when turning the tap partly on so as to regulate the
supply, instead of turning the plug B, I turn the inner plug C, by this meaus the
surface of the outer plug is not exposed to the action of the steam and water,
the chamber or passago D in the inner plug C is conical; In gas taps shown at
Figs 3, 4 and 5 I construct the inner plug C as usual but the hole for the passage
of gas is bored conical, or is smaller at the side for admitting gas; on turning the
gas partly on, the gas does not deviate in its course, but takes a direct line of
passage, or instead of the above the inner plug may pass up the inside of the plug
proper and be adjusted by a screw D, and when turning the gas partly on to
regulate it, I can employ the screw D which reduces the opening but still does not
derange the straight course of the gas, another advantage this construction of gas
tap has, is that when an ordinary gas tap is turned partly on, if the plug is slack,
the pressure of the gas acting upon the angle of the hole in the plug, will at times
turn on the gas, but by using the above arrangement this cannot possibly occur.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is
(1) I claim in steam and water taps the uso and employment of an inner plug
for regulating purposes, and for preventing the wear and tear of the outer plug as
shown and described.
(2) In gas taps the use and employment of a conical bored plug for regulating
and steadying purposes as shewn and described, with or without the regulating
Bcrew.
