Improvements in and relating to Illuminating Devices.
1, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of Middle-
sex, Patent Agent, do hereby declare the nature of this invention and in what
manner the same is to be performed, as communicated to me by Pieter Hendrik
Verbeek, of Herrnhut, near Löbau, Saxony, Merchant, to be particularly described
and ascertained in and by the following statement:.
-
The object of this invention is to produce illuminating device of star-like form,
chiefly intended for use on festive occasions such as at Christmas time, or for
illuminations &c.
The distinguishing feature of the illuminating device forming the subject of
this invention is that the source of light is surrounded by a metal frame of cube-
like or similar shape, and the intermediate spaces of the frame filled up with
pyramids" made of transparent or translucent material and easily detachable.
The accompanying drawings illustrate an illuminating device of the kind
above referred to adapted for illumination by a petroleum lamp. Fig. 1 is an
elevation representing the complete device; Fig. 2 shows a four-sided pyramid
in end and side elevation and the means of fixing same to the frame of the device,
and Fig. 3 shows the same of a three sided pyramid.
The pyramids a are made of some transparent or translucent material, such as
paper, celluloid, gelatine, &c. and are furnished with a metal frame bottom b
around the lower edges, which bottom bis bent in the manner of a clamp on two
sides lying opposite to each other. In the case of the four-sided pyramids, shown
in Fig. 2, the edges of the bottom b are bent in parallel planes and are of unequal
length in order that the frame stays c may be inserted between them with
facility.
'
The bottoms of the three sided pyramids with the edges turned up on two
sides are pushed behind the stays c of the triangular spaces in the frame of the
device.
The detachableness of the pyramids is intended, in addition to the possibility
of producing varied effects of colour thereby attained, to enable the whole of the
illuminating device when taken to pieces to be easily conveyed.
The transparent or translucent pyramids may be covered with printed advertise-
ments, allegorical representations or other ornamentations.
In the form shown by way of example in the drawings the illuminating device
is suspended by means of an arm e extending upwards and furnished with a
hook. The arrangement may, however, be so carried out that the illuminating
device, instead of being suspended to a horizontal surface such as a ceiling, may
lodge against a vertical one such as a wall and in the latter case, instead of the
arm e, a loop or eye projecting from the side is employed, and, if the illuminating

page_text: device is to be fixed direct on the wall, the part turned to the latter may be
flattened, without going beyond the scope of the invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
―:
An illuminating device of star-like form, consisting of a many sided frame,
behind or to the stays of which four-sided or three-sided pyramids of some trans-
parent or translucent material such as paper, celluloid, gelatine &c. are detachably
connected substantially as described with reference to Figs. 1 and 2 or Figs. 1
and 3 of the accompanying drawings.
