page_text: LETTERS PATENT to Thomas Fletcher of Warrington in the county of
Lancaster for an Invention of IMPROVEMENTS IN OR APPLICABLE TO GAS
BURNERS FOR BOILING, GRILLING, TOASTING AND OTHER SIMILAR PURPOSES
PROVISIONAL SPECIFICATION left by the said Thomas Fletcher at the
Office of the Commissioners of Patents on the 6th September 1883.

"IMPROVEMENTS
IN OR APPLICABLE TO GAS BURNERS FOR BOILING GRILLING TOASTING AND OTHER
SIMILAR PURPOSES
כי
These Improvements relate to Gas Burners having or being used in combination
with a flange or deflector plate for toasting grilling and similar purposes and have
for their object to allow such burners to be reversed for boiling without lifting the
hot grid or disturbing the cooking vessels resting thereon and so avoiding risk of
buins or other accidents and annoyances.
«
The burner may have the flange or deflector plate cast upon or fixed to the body
of the burner or the flange may be fixed and the burner be rotated alone I prefer
to use a tubular or straight line" burner mounted on suitable bearings. To one
end of the burner I attach a lever or a pinion gearing into a rack by the Motion
of which the burner may have half a revolution imparted to it so as to reverse the
position of the flame from above to below or the reverse Any other device may
be employed for reversing the burner and it may the so arranged hat a series of
burners may be returned or reversed simultaneously

THOMAS FLETCHER of Warrington in the County of Gloucester IMPROVEMENTS
IN OR APPLICABLE TO GAS BURNERS FOR BOILING GRILLING TOASTING AND OTHER
SIMILAR PURPOSES
カ
These improvements relate to Gas burners having or being used in conjunction
with a flange or deflector plate for toasting grilling and similar purposes and have
for their object to allow such burners to be reversed for boiling without lifting the
hot grid or disturbing the cooking vessels resting thereon and so avoiding risks of
burns or other accidents and annoyances
The burner may have the flange or deflector plate cast upon or fixed to the body
of the burner or the flange may be fixed and the burner alone be reversed or
rotated.
In order that my invention may be more readily understood and carried into
practical effect I have hereunto appended a sheet of Drawings having letters of
reference marked thereon similar letters denoting similar parts in the various
figures.
Fig. 1 shews an end view and Fig: 2. a plan of a single burner-Fig 3 shews an
end view and Fig: 4 a plan of a series of burners to which these improvements
have been applied-Figs 5. 6 and 7 shew modifications of the reversing apparatus
I prefer to use a tubular or straight line burner A mounted upon or by suitable
bearings B. To one end of the burner and preferably at the end of the injection
tube I attach, cast or otherwise secure a pinion C, gearing into a rack D so that by
the reciprocal motion of the rack the burner may be turned through half a
revolution. The turning of the burner through precisely half a revolution may be
accomplished by various methods. Thus the rack may have half as many teeth
only as the pinion as shewn in Fig. 5 or the pinion may have teeth formed upon
half its circumference only as shewn in Fig: 6, or stops may be attached to the
pinion as shewn at E in Fig 7 or the stops may be attached to the rack itself as
shewn at F Figs. 1 and 3.
A series of burners may be rotated simultaneously by the use of a series of racks
or a continuous rack carried upon the same reciprocating rod G and gearing into
the pinions upon the burners as shewn in Figs: 3 and 4 Single burners may also
be rotated by hand in which case a lug stud or handle may be attached to any
part of the burner for greater convenience and the pinion and rack may be
omitted
The flange or deflector plate may be cast upon or secured to the burner as shewn
at H. H. Figs. 1 and 2 or it may be fixed and independent of the burner as shewn
at H¹ H¹ H¹ H₁ Figs 3 and 4.
Having now described the nature of my invention and the manner in which it
may be carried into practical effect I desire it to be understood that I do not limit
myself to the precise details, as these may be varied without departing from my
Invention but what, I consider to be novel and therefore claim, is:-
The combination of a deflector plate or plates with a reversible gas burner or
burners substantially as herein before set forth and described.
In witness whereof I the said Thomas Fletcher have hereunto set my hand and
seal this fifth day of March in the year of our Lord one thousand eight hundred
and eighty four.
