IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY OF GAS TO BURNERS
Year: 1879

page_text: LETTERS PATENT to Thomas Thorp, of Whitefield, in the County of Lancaster,
Architect, and Robert Tasker, of Prestwich, in the same County, for the
Invention of "IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY
OF GAS TO BURNERS."
Sealed the 7th May 1880, and dated the 11th November 1879.
PROVISIONAL SPECIFICATION left by the said Thomas Thorp and Robert
Tasker at the Office of the Commissioners of Patents on the 11th November
1879.
THOMAS THORP, of Whitefield, in the County of Lancaster, Architect, and ROBERT
TASKER, of Prestwich, in the same County. "IMPROVEMENTS IN APPARATUS FOR
REGULATING THE SUPPLY OF GAS TO BURNERS."
This Invention has for object improvements in apparatus for regulating the
supply of gas to burners. For this purpose we cause the gas on its way to the
burners to pass through oblique or slanting passages into a chamber in which is a
disc with radial projections or vanes, and carried by a spindle provided with
equilibrium valves.
Gas entering the chamber above referred to causes the disc, its spindle, and the
valves to rotate, and excess of pressure in the chamber below the disc will cause
it to rise, carrying with it the valves, and thereby more or less closing the passages,
and so regulating the quantity of gas passing on to the burner.

THOMAS THORP, of Whitefield, in the County of Lancaster, Architect, and ROBERT
TASKER, of Prestwich, in the same County. "IMPROVEMENTS IN APPARATUS FOR
REGULATING THE SUPPLY OF GAS TO BURNERS."
This Invention relates to improvements in apparatus for regulating the supply of
gas to burners. For this purpose we cause the gas on its way to the burner to
pass through oblique or slanting passages into a chamber in which is a disc with
radial projections or vanes, and carried by a spindle provided with equilibrium
valves.
Gas entering the chamber above referred to causes the disc, its spindle, and the
valves to rotate, and excess of pressure in the chamber below the disc will cause it
to rise, carrying with it the valves, and thereby more or less closing the passages
and so regulating the quantity of gas passing on to the burner.
Referring to the accompanying Drawings, Fig. 1 is a vertical section of our
improved gas regulating apparatus taken in the line A, A, of Fig. 3; Fig. 2 is a
vertical section at right angles to Fig. 1, taken in the line B, B, of Fig. 3; and
Fig. 3 is a sectional plan taken in the line C, C, of Figs. 1 and 2.
a is a metal case or chamber connected at one end to the gas supply pipe b, and
having screwed into its other end the burner 6¹; is a cylinder or chamber fixed
in the case or chamber a, into which the gas on its way to the burner passes
through oblique or slanting passages c¹; d is a spindle passing through the centre
of said chamber, on to which is fixed a disc e with radial projections or vanes, and
equilibrium valves f. f. The spindle is supported in a footstep or bearing g in the
bottom of the cylinder or chamber c; h, h, are passages for the gas flowing to the
burner.
Gas from the pipe b, entering the cylinder or chamber c through the passages c',
impinges upon the disc e causing it and the valves f, f, to rotate, thereby providing
a constant and equal supply of gas to the burner, but when there is an augmen-
tation of pressure from the pipe b the excess of pressure of the gas underneath the
disc e causes it and the valves to rise, thereby closing more or less the passages h, h,
and consequently regulating the quantity of gas passing to the burner.
Having described the nature of our said Invention, and explained in what manner
the same is to be or may be performed or carried into practical effect, we would have
it understood that what we consider to be novel and original, and therefore claim
as the Invention secured to us under the Letters Patent hereinbefore in part recited
is the constructing and arranging apparatus for regulating the supply of gas to
burners, substantially as herein before described and illustrated, and particularly
causing the gas on its way to the burner to pass through oblique or slanting
passages into a chamber in which is a disc with radial projections or vanes, such
disc being carried by a spindle, provided also with equilibrium valves operated by
the gas pressure against the disc, substantially as and for the purpose set forth.
In witness whereof, I, the said Robert Tasker, have hereunto set my hand
and seal, this Seventh day of May, in the year of our Lord One thousand
eight hundred and eighty
