ROBERT WILLIAM BRETT,. of Hertford, in the County of Hertford. "IMPROVE-
MENTS IN LANTERNS FOR PUBLIC OR PRIVATE LIGHTING, AND IN THE MODE OF
SUPPORTING THE SAME."
This Invention has for its objects the construction of lanterns in a light, elegant,
and economical manner, easy of attachment and adjustment to their supports, which
said supports are also in their turn easily attached to the lamp column or bracket;
the principal object being to reduce the framework of the lantern and supports as
much as possible consistent with the requisite strength, so as to avoid all unnecessary.
interception of light.
The Invention consists in making the lower part of the framework of the lantern,
and also that where it is of largest diameter, of wrought iron. These portions of
the frame are made to receive the plates of glass, and are each formed with an eye
furnished with a set screw, and capable of slipping over the support, which is made
of wrought iron of about an inch and a half wide by three-eighths of an inch thick.
The support is curved, and at its bottom part is fashioned into a ring or socket
that slips over the upper or spigot end of the lamp-post, and on which it rests, firmly?
In case the support is intended to be attached to a bracket it may be either.
welded, clipped, bolted, or fastened thereto in any suitable. manner. To fix
the lantern in position, all that is necessary to be done is to slip the eyes of the
lantern frame over the support, adjust it to a suitable height with regard to the
burner, when the set screws may be turned and the lantern secured with great
facility.

the said Robert William Brett in the Great Seal Patent Office on the 27th
November 1877.
"IMPROVE-
MENTS IN LANTERNS FOR PUBLIC OR PRIVATE LIGHTING, AND IN THE MODE OF
SUPPORTING THE SAME."
ROBERT WILLIAM BRETT, of Hertford, in the County of Hertford.
This Invention has for its objects the construction of lanterns in a light, elegant,
and economical manner, easy of attachment and adjustment to their supports, which
said supports are also in their turn easily attached to the lamp column or bracket,
the principal object being to reduce the framework of the lantern and support as
much as possible consistent with the requisite strength, so as to avoid all unnecessary
interception of light. In addition to these advantages this lantern offers great
facilities for repair, as a broken pane of glass may be removed and a fresh one
inserted in a few minutes without the application of putty.
The Invention consists in making the lower part of the framework of the lantern, 1
and also that where it is of largest diameter, of wrought, malleable, or cast iron.
These portions of the frame are made to receive the plates of glass, and are each
formed with an eye furnished with a set screw, and capable of slipping over the
support, which is made of wrought iron of about an inch and a half wide by three-
eighths of an inch thick.
1. J
The support is curved, and at its bottom part is fashioned into a ring or socket
that slips over the upper or spigot end of the lamp-post, and on which it rests firmly.
In case the support is intended to be attached to a bracket it may be either
clipped, bolted, or fastened thereto in any suitable manner.
In order that the foregoing may be more easily understood, Drawings are attached a
hereto of which the following is a description:-
Fig. 1 is an elevation of the lantern, its supports, and parts of the lamp column.
Fig. 2, drawn to a larger scale, is a section of a part of the cover of the lamp and
upper ring; and Fig. 3, also drawn to a larger scale, is a section of the lower ring.
In Fig. 1, A, A, are the panes of glass retained in their position by the upper
ring B, to which are soldered or otherwise fastened copper clips, which are bent
down and over the glass as seen in Fig. 2, C being the copper clip, A the glass, and
D part of the top of the lantern. E, Fig. 1, is the lower ring which has a groove in
it as depicted in Fig. 3, and receives the lower edges of the panes of glass. Each
ring is furnished with an eye F that slips over the bar or support G, and is fixed
thereto by screws H, H.
It will be seen that the lower end of this bar is formed into a ring I of such a
size as to clasp the spigot end of the top of the lamp column.
The roof or dome of the lantern D is fastened to the upper ring by two or more
set screws J, shown more distinctly in Fig. 2. In the case of lanterns to be attached
to brackets, the support G may be made as shown in dotted lines in Fig. 1, the
upper part being fixed to the bracket by bolts or otherwise.
'
In each of the Figures similar letters refer to the same parts.
To fix the lantern in position, all that is necessary to be done is to slip the eyes
F, F, of the lantern frame over the support G, adjust it to a suitable height with
regard to the burner, when the set screws H, H, may be turned, the lantern being
secured and subsequently placed on the lamp column with great facility.
Having now described and particularly set forth the nature of this Invention
and the manner in which the same is or may be used or carried into effect, I would
observe in conclusion that I do not confine or restrict myself to the precise details
or arrangements which I have described or referred. to, as variations may be made
therefrom without deviating from the principles or main features of this Invention,
but what I consider to be novel and original, and therefore claim as the Invention

page_text: secured to me by the herein-before in part recited Letters Patent is, the construction
of lanterns and their supports as herein described and shown on the Drawings.
In witness whereof, I, the said Robert William Brett, have hereunto set my
hand and seal, this Twenty-sixth day of November, in the year of our Lord
One thousand eight hundred and seventy-seven.
