I, JAMES KILPATRICK, of Barrhead, in the County of Renfrew,
North Britain, Gasfitter, do hereby declare the nature of the said
Invention for "IMPROVED CONSTRUCTIONS OF GASALIERS AND REFLECTORS, WHICH
LATTER ARE ALSO APPLICABLE TO OTHER LIGHTS AND GAS JETS," to be as
follows:-
This said Invention consists of new or improved constructions and
arrangements of the parts of gasaliers, cach having a new or improved
construction of polygonal and curvilinear reflector placed in the centre
between the lights, with as many reflecting sides in plan as there are
branch lights (as from three to eight in single or groups of jets), each
face however being made of a hollow, curved, or segmental form in the
elevation or side view, formed of narrow parallel strips of glass, silverized
on the back, which may be made from one to three inches broad,
according to the curve, and laid close edge to edge horizontally round or

page_text: over the whole of cach curved reflecting face of the polygonal reflector,
so as in reality to form each polygonal face (in the curved direction)
also of narrow flat reflecting faces of the width of the said narrow strips,
having the lights preferably nearly opposite the centre or middle of each
said curvilinear face of the polygonal reflector. The sustaining frame
of the reflector is preferably formed hollow of sheet metal, with ribs at
the vertical front corners or angles to hold the ends of the strips of glass,
which form the said narrow reflecting faces; these strips being
necessarily shortest at the deepest curved or convex part, with the sheet
metal back curved nearly close behind the glass to protect it, while the
top and bottom edges may be made to hold the upper and lower strips of
silverized glass properly in position by their edges, and have when
desired an ornamental metal edging projecting up from the top and
pendent from the lower edges all round, the latter securing the outer
edges of a glass bottom silverized on the upper back side and inserted in
picces secured also in the centre eye piece, through which the lower end
of the pendent stem of the gas pipe branches off below to the several
arms and lights, and carrying the whole gasalicr from the top or roof
plate. The said stem or other arms or chains carry, close over the said
new or improved construction of central curved polygonal reflector, an
ordinary annular conical reflector, preferably of the construction formed
of angled radial strips of silverized glass, but it might be of other
ordinary forms and constructions of such top light downward reflectors;
the outer lower edges of its carrying frame might or might not have an
ornamental pendent edging as desired, and the central pendent stem or
gas pipe carrying the whole, and the branch arms might be concealed
or encased by ornamental designs in metal or cut glass as other gasaliers
are, and when desired (as in the case of high pendent gasaliers or top
roof or "sun lights," for which these improvements are very applicable)
a glass or other duct with a bell-mouth may be secured or erected over.
the central opening of the top conical reflector to carry off the heated
products of combustion and give a better ventilation when the lights are
:burning.
"
The novelty in this improved gasalier is the arrangement of parts with
the said new or improved construction of central reflector, which is more
simple and easily made than those heretofore in use, and gives an
ant etuanoth and lianaw

page_text: improved polygonal and curved reflector is also applicable to groups of .
three or more other gas jets or other oil or candle lights, whether of the
hanging, stand, or bracket class, so that it is arranged in the centre of
the lights with one of the said reflecting glass faces always opposite and
3some distance from cach light.
