for the term of fourteen years, subject to a proviso or condition for us, the
said Joseph Lucas and William Baylis, to cause a description of the nature
of the said Invention, and in what manner the same is to be performed, by
writing under our hands and scals, to be inrolled in His Majesty's High

page_text: NOW KNOW YE, that we, the said Joseph Lucas and William Baylis,
in compliance with the said proviso or condition, do hereby declare that our
said Invention is described in the Plan or Drawings hereunto annexed, and
particulars thereof hereunder written.
In witness whereof, we havo hereunto set our hands and seals, this
Ninth day of November, in the year of our Lord One thousand seven
hundred and ninety-threo.
Particulars of the Invention of Joseph Lucas, of Long Acre, in the Parish
of Saint Martin-in-the-Fields, in the County of Middlesex, Oil Merchant, and
William Baylis, of Red Lion Street, in the Parish of Saint Andrew, Holborn,
in the said County of Middlesex, Tin Plate Worker, referred to by the above
Deed Poll, and as is more particularly mentioned and described in a Plan or
Drawings hereunto annexed, cousists in making, furnishing, and fitting up
glass and tin and other metal lamps and lanterns, burners and frames, with
lens glasses in various shapes and forms, to hang or fix in globular, vase, and
other shaped lamp glasses or lanterns, and to be used in lighting streets,
lanes, courts, passages, halls, staircases, and for other places and purposes.—
The end and design of these lamps is to diffuse and give a strong and general
light in various directions, with much less trouble and expence than any
hitherto invented. The said lamps may be made of tinned iron plate, or other
metals, with one, two, three, four, or more tubes or wick-holders to each lamp,
to contain the necessary oil and cotton, and suit the situation, place, and
purposes for which the lamps are intended. The tubes or wick-holders may be
made flat, round, or of any other form, and is affixed and soldered to the body
of the lamps in an oblique direction, to feed and supply the fire of the lamps
with oil more freely and effectually than such as are placed in a perpendicular
or more upright direction. A metal receiver is placed under every tube or
wickholder, to prevent waste and overflowing of the oil.
burner or burners, have one, two, three, four, or more
affixed to each of them, a merciscus lens, that is, being convex on the one
side and concave on the other. A pland convex or a double convex may be
made use of, and are placed in such a manner as to act both as a refractor
and reflector to every light, and being so placed, every possibility of shade is
avoided, and are so contrived as to be taken off tlic lamp burners singly or
two at one and the same time. The lamps may be made use of without a leus
or lenses if required. The lamp burners, with the lenses, are suspended by a

tinned iron plate or other metal running across from the extremity of the
outer part of the top of the globular vase or other shaped glass lamp or lantern
in which the lamp burner or burners are placed and made use of, and framed
to fix into sockets or loops, one on each side; soldered to a metal rim which
encircles the globular or other shaped lamp glasses or lanterns. The lamps
may be made to hang on a wire or wires running across the top of the lamp
glasses or lanterns, and the lamp burners, with the lens or lenses, and other
things belonging, may be taken out of the lamp glasses, lantern or lanterns
together, for the purpose of trimming, replenishing with oil, and cleansing the
same; the lenses may be taken out' seperately.
The Invention of the said Joseph Lucas and William Baylis also consists in
the making and furnishing of a lamp or lamps for the lighting of halls, staircases,
passages, and other places and purposes, and are made of tinned iron plate,
brass, or other metals, in various shapes and forms, with one, two, three, four,.
or more glass lenses. The body of the said lamp or lamps is gradually
supplied with oil by a fountain or reservoir, which is taken off occasionally to
replenish the lamp and lamps with oil, and suspended by chains or wires, to
hang in the several lamp glasses or lanterns in which they are made use of, or
they may be used without the fountain or reservoir if required.
Figures 1 represent the forms of several lamp burners which contain the
oil to hang in lamp glasses or lanterns.
Figures 2 represent the cotton wick-holders.
Figure 8 represent the glass lenses, and the manner in which they are
affixed to the bodies of the burners which contain the oil.
