COMPLETE SPECIFICATION.
An Improvement in Lanterns for Streets and other Exposed
Situations.
I, JOHN HOLMES SHELDRAKE, of 14, Palmer Street, Westminster, in the
County of London, Gas Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :—
My invention relates to the construction of a lantern for a street and other
exposed situation in such a manner that it can be readily put together and taken
apart, the glasses being fixed without putty or other cementing material, as I shall
describe referring to the accompanying drawings.
Fig. 1 is a side elevation, Fig. 2 is a vertical section and Fig. 3 is a sectional
plan on the line X X Fig. 1, of a four sided lantern according to this invention.
The lantern consists of the following parts; a square base plate A having a
central hole for gas pipe and a hole at each angle for the angle posts B, having
also on three sides grooves a to receive the lower edges of side glasses-four angle
posts B preferably of steel or malleable cast iron, each terminating at each end
with a part b screw threaded to receive a nut C-a square roof frame D having
a hole at each angle for the angle post B having on three sides catches d to
receive the upper edges of glasses and having hinged to it at one side a trapezoidal
door frame E which has catches e and e¹ to receive the upper and lower edges of
the glass a roof F having a central wind guard f and having four holes for the
angle posts B.
The glasses are trapezoidal, those of the lantern being put in place by inserting
from within the lantern, the upper edge within the catches d which are deeper
than the grooves a, then after passing the lower edge over the inner side of the
groove a, dropping that edge into the groove, the upper edge being still engaged
in the catches d. In like manner the glass for the door E has its upper edge
engaged in the upper catches e, which are deeper than the lower catches e¹ and
then on passing the lower edge of the glass over the lip of the catches e¹ the
glass is dropped into these, its upper edge being still engaged in the upper
catches e.
The lantern is put together by placing the base A on the four supports S
projecting up from the lantern post, inserting the lower ends of the angle posts B
into the holes of A and S and securing them by nuts C, then placing the roof
frame D and roof F on the upper ends of the angle posts and securing them by
nuts C-inserting the side glasses as described and hanging the previously glazed
door by the hinge to the roof frame, the lantern being then completed.
Instead of a single door E, there may be two, one opposite to E.
Although I have described a four sided lantern obviously a similar construction
would apply to a lantern of polygonal form, or of circular form the glasses in that
case being bent.

tion and in what manner the same is to be performed, I declare that what I
claim is :-
A lantern constructed as described with reference to the drawings.
