AN IMPROVED APPARATUS FOR REGULATING THE FLOW OF GAS TO BURNERS
Year: 1880

page_text: LETTERS PATENT to Thomas Thorp, of Whitefield, and Robert Tasker, of
Prestwich, both in the County of Lancaster, for an Invention of "AN
IMPROVED APPARATUS FOR REGULATING THE FLOW OF GAS TO BURNERS."
PROVISIONAL SPECIFICATION left by the said Thomas Thorp & Robert
Tasker at the Office of the Commissioners of Patents on the 4th December
1880.
THOMAS THORP, of Whitefield, and ROBERT TASKER, of Prestwich, both in the
County of Lancaster. "AN IMPROVED APPARATUS FOR REGULATING THE FLOW
OF GAS TO BURNERS."
The apparatus consists of a metallic cylinder open at the lower end and closed
at the upper end with the exception of a central recess, into each side of which a
cross passage communicating with the burner opens; a footstep fits into the lower
end of the aforesaid cylinder, through which are oblique or other perforations, and
having on the inner side a central bearing; we make use of a circular metallic
disc (fitting loosely in the aforesaid cylinder), on the lower side of which is a
spindle working in the aforesaid bearing in the footstep, and on the upper side is a
tube having perforations in its opposite sides near the dise and working in the
central recess in the upper end of the aforesaid cylinder.
The whole of the above apparatus fits into a case, on the top of which may be
screwed the burner or tube communicating with the burner, and the other end may
be secured to the gas supply pipe.
By the use of this apparatus the gas may be consumed to the greatest
advantage

of an Order of the Lord Chancellor, filed by the said Thomas Thorp & Robert
Tasker in the Great Seal Patent Office on the 14th June 1881.
THOMAS THORP, of Whitefield, and ROBERT TASKER, of Prestwich, both in the
County of Lancaster. "AN IMPROVED APPARATUS FOR REGULATING THE FLOW
OF GAS TO BURNERS."
The apparatus consists of a metallic cylinder open at the lower end and closed at
the upper end with the exception of a central recess, into each side of which a
cross passage communicating with the burner opens; a footstep fits into the lower
end of the aforesaid cylinder, through which are oblique or other perforations, and
having on the inner side a central bearing; we make use of a circular metallic disc
(fitting loosely in the aforesaid cylinder), on the lower side of which is a central
spindle working in the aforesaid bearing in the footstep, and on the upper side is a
tube having perforations in its opposite sides near the disc and working in the
central recess in the upper end of the aforesaid cylinder. The whole of the above
apparatus fits into a case, on the top of which may be screwed the burner or tube
communicating with the burner, and the other end may be secured to the gas
supply pipe. By the use of this apparatus the gas may be consumed to the greatest
advantage.
And in order that our Invention may be fully understood we will describe the
accompanying Sheet of Drawings, reference being had to the figures and letters
marked thereon.
Figure 1 is an elevation of our improved gas regulator, and Figure 2 is an
elevation in section of the same, showing the details; Figure 3 shows the regulator
applied to a street lamp.
a is a cylinder made by preference of white metal, in the upper part of which
is a recess a¹ communicating by cross passages with the space below the burner b;
at the bottom of the cylinder a is fitted the footstep C, through which are oblique
or vertical passages; d is a circular disc having a shaft or spindle e which fits in
the footstep C; on the disc d is also a tube f; near the bottom of which are
apertures, the upper part of the tube f fits in the recess in the top of the cylinder a;
the tube f fitting in the recess a', and the spindle e fitting in the footstep C keep
the disc d in a horizontal position and ensure regularity in the flow of gas; g is
the outer casing formed in two parts; the lower part of g is connected to the gas
supply pipe i, and in the upper part of g is fitted the burner b, or the tube j (when
the regulator is applied to a street lamp) in which the burner is fixed. The gas
follows the direction indicated by the arrows; it enters the bottom of the casing,
passes through the holes in the footstep C, then round the edge of the disc d,
through the apertures in the tube f, through the cross passages at the top of the
cylinder a, and thence to the burner b.
Having stated the nature of our. Invention, and described the manner of
performing the same, we declare that we claim,—
1. The spindle e on the disc d carrying the tube f, as shown and described.
2. The combination and arrangement of parts forming an improved gas regulator,
as shown and described.
In witness whereof, I, the said Thomas Thorp, for myself and on behalf of
the said Robert Tasker, have hereunto set my hand and seal, this Thirteenth
day of June, One thousand eight hundred and eighty one.
