page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BAYLIS, of Red Lyon Street, in the Parish of Saint Andrew, Holborn, in the
County of Middlesex, Tin Plate Worker, send greeting.
WHEREAS His present Majesty King George the Third by His Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster
the Thirtieth day of May last past, hath given and granted unto me, the said
William Baylis, my executors, administrators, and assigns, special licence,
full power, sole priviledge and authority, to make, use, exercise, and vend
within England, Wales, and the Town of Berwick-upon-Tweed, during the
term of years therein expressed, my Invention of "A CERTAIN IMPROVED LAMP
FOR LIGHTING OF STREETS, LANES, HALLS, HOUSES, WAREHOUSES, SHOPS, AND
VARIOUS OTHER PURPOSES, WHEREBY LABOUR IS CONSIDERABLY REDUCED, AND A GREAT
SAVING MADE IN OIL AND OTHER MATERIALS;" in which said Letters Patent
there is contained a proviso, obliging me, the said William Baylis, by an in-
strument in writing under my hand and seal, to cause a particular description
of the nature of my said Invention, and in what manner the same is to be
performed, to be inrolled in His Majesty's High Court of Chancery within one
calendar month next after the date of the said recited Letters Patent, as in
and by the same, (relation being thereunto. had) may more fully and at large

page_text: NOW KNOW YE, that I, the said William Baylis, in compliance with the
said proviso, do hereby declare that the nature of my said Invention, and tho
manner in which the same is to be performed, is particularly described and
ascertained in and by the Plan hereunto annexed and referred to, and the
following particulars and description thereof, (that is to say):-
Figures 1, the shapes or forms of several lamp burners which contain the
oil, to hang in the lamp glasses or in the lanterns; Figures 2, the bottom wick
holders with the oil receivers; Figures 3, the glass lenses, with the manner in
which they are affixed to the bodies of the burners containing the oil; Figures 4,
the wires by which the lamps are suspended; Figures 5, the lamp burners to
be placed or fixed in an angular manner, form, or position, at the corners of
any street, lane, court, passage, or other place necessary to be lighted;
Figure 6, the lamp burners, with a fountain or reservoir either to hang or
stand in a globular vase, or other shaped or formed lamp glass, or in a lanteru,
and which may be used to read or write by, or for any other convenient purpose.
This lamp, made and fitted up in manner above described, will diffuse and give
a strong general light in various directions, and may be made of tinned iron
plate, or any other metal fit for the purpose, with one or several tubes or wick-
holders to cach lamp, to contain the necessary oil and cotton, as may suit the
situation and purpose for which it is intended. The tubes, or wick-holders,
may either be made flat, round, oval, or of any other shape, or form, and
affixed to the body of the lamp in an oblique direction, to feed and supply the
fire of the lamp with oil. A metal receiver, formed either from or sol-
dered to the lamp burner, should be placed under every tube or wick-
holder to prevent any waste and overflowing of the oil. The lamp or burners
may have one or more glass lenses affixed to each of them. A plano convex,
that is boing flat on one side and convex on the other; a merciscus, which is
concave on one side and convex on the other; a double convex, which is con-
vex on both sides; a flat plano convex, whose convex side is ground into several
little flat surfaces or lenses of other forms and shapes may be made use of, and
placed in such manner as to act both as a refractor and reflector to every light,
whereby the usual shade attending all other lamps is in a great measure
removed, and the lenses are so contrived as to be taken off the lamp burners,
either singly or two at a time, for the purpose of trimming, replenishing with
oil, nud cleansing the lamp, which may be used either with or without the
lenses at pleasure, or the lenses may be affixed to the lamp burner. The lamp
burners, with the lenses, are suspendled by wires in various forms and directions,
soldered either to another wire, or a tinned iron plate, or other metal, running
across the extremity of the outer part of the top of the globular vase. or other

page_text: shaped or formed lamp glass, in which the burners are placed and made use
of, and so framed as to fix into sockets or loops on each side, soldered to a
metal rim, which encircles the globular or other shaped or formed lamp glasses.
The lamp may be made to hang on wires running across the top of the.lamp
glasses, and the lamp burners with the lenses, and other necessary things, may
be taken out of the lamp glasses, or out of the lanterns altogether, for the pur-
pose of trimming, &c., or the lenses may be taken out singly as above men-
tioned. The lamp burners have one or more pieces of cork, sponge, or other
elastic substance affixed to each of the bodies of them, and the same to each of
the lenses (if required) to prevent the lamp burners from striking against and
breaking the lamp glasses or lanterns in which they may be placed, and to
which they are liable, or they may be made and used without if required.
In witness whereof I, the said William Baylis, have hereunto set my
hand and seal, this Twenty-ninth day of June, in the year of our Lord,
One thousand seven hundred and ninety-five, and in the thirty-fifth year
