PROVISIONAL SPECIFICATION.
Improvements in Union Gas Burners.
I GEORGE ROBERTSON HISLOP of the Gas Works Paisley in the County of
Renfrew Engineer and Gas Works Manager do hereby declare the nature of this
invention to be as follows :-
This invention consists in constructing union gas burners in such a manner as
shall render the angle of inclination of the holes in said burners as also the angle
of impingement of the issuing gas jets adjustable in relation to each other and to
any required degree.
This is effected by attaching to a nipple inserted in the gas pipe two hollow arms
the upper ends of each of which are adjustably connected to an inclined burner
tube working on a trunnion having on its end a spur wheel geared with a rack made
in a radial slot in a quadrant or plate and upon which the degree of angularity of
the gas tubes is indicated the position of the tubes relatively with each other
being adjustable by means of thumb screws or their equivalents acting on the spur
wheels.
When employed for photometrical or gas testing purposes a pressure gauge or
gauges is or are attached to the lower end of one or both of the gas burner tubes
but when used for ordinary gas lighting purposes the lower ends of these tubes are
permanently closed.
Instead of connecting the hollow arms to the nipple as above described the
lower ends of these arms may be connected to a hollow standard, through which
the gas is passed, by means of a hollow reciprocating piston or plunger working in
said standard and with this modification the slots in the quadrant and the spur
wheel and rack may be dispensed with and a slide on the quadrant substituted to
carry the upper ends of the arms and the gas burner tubes.

COMPLETE SPECIFICATION.
Improvements in Union Gas Burners.
I, GEORGE ROBERTSON HISLOP of the Gas Works, Paisley in the County of
Renfrew Engineer and Gas Works Manager do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
This invention consists in constructing union gas burners in such a manner as
shall render the angle of inclination of the holes or issuing orifices in said burners
as also the angle of impingement of the gas jets adjustable in relation to each
other and to any required degree and as shewn in side elevation at Figure 1 and
in end elevation at Figure 2 of the accompanying drawings this is effected under
one modification by attaching to a side branch on the nipple A for attaching the
burner to the gas pipe the lower ends of two hollow arms B whose upper
extremities are each connected to a separate inclined burner tube C carried by
clamps D on a quadrant E the degree of angularity of the burner tubes relatively
to each other being adjusted by spur wheels F which as more particularly shewn
by the enlarged detailed elevation and cross section Figures 3 and 4 respectively
are geared with racks G made in radial slots H in the quadrant or plate. The
spur wheels F are turned to regulate the positions of the tubes C by thumb nuts I

of the clamps and scales are marked on the quadrant to indicate the degree of
angularity.
The two plates of the clamps are screwed or bolted together above and below
the quadrant E and the front plates are formed on or connected to enlargements C¹
on the gas tubes these enlargements having the nipples for connecting the upper
ends of the hollow arms B made on or attached to them.
When the improved burner is used for photometrical or gas testing purposes a
pressure gauge or gauges is or are connected to the lower end of one or both of the
burner tubes C but when used for ordinary gas lighting purposes the lower ends of
these tubes are permanently closed.
Figure 5 illustrates in side elevation and Figure 6 in plan a modification of the
arrangement wherein the hollow arms B are dispensed with and the quadrant E
acts as a receiver for the gas from the gas pipe from whence it is distributed to the
burner tubes C through the upper parts of the clamps D. The clamps embrace
the upper surface of the box shaped quadrant E and they are packed gas tight
thereon at their ends by strips of leather or equivalent material and within the
length covered by the travel of each clamp a hole or opening is made on the upper
surface of the quadrant through which the gas passes outwards to the burner tubes
these being connected to the tops of the clamps.
The adjustment under this arrangement is effected by a screw L which is guided
at M and has a right and left hand thread upon it one thread passing through a
nut N attached to one clamp whilst the other passes through a like nut connected
to the other clamp so that by turning the screw from either end the angularity of
the burner tubes relatively with each other is varied the degree of angularity
being indicated on a scale made on the box shaped quadrant and which scale is seen
through openings in the front plates of the clamps.
The clamps are bound in any adjusted position by thumb screws which pass
through their lower ends and act against loose plates y bearing when screwed up
against the under surface of the quadrant. The quadrant has nipples or branches O
furnished with stop cocks for the connection of a pressure gauge or gauges when
using the burner for gas testing or photometrical purposes.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A union gas burner so constructed as to render the angle of inclination of the
issuing holes in said burner and also the angle of impingement of the gas jets
adjustable in relation to each other to any required degree substantially as
described.
