page_text: I, JOHN HENRY STONE of Hamilton, Ontario, in the Dominion of Canada Manu-
facturer 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 refers to improved means as hereafter described of fixing or securing
the globes of tubular lanterns so that they may be easily removed for lighting,
trimming, filling, and cleaning, and may be again replaced in position with the
greatest facility and without risk of breakage, and when so placed in position they
are held in a more secure manner, while at the same time the constructional details of
such fixings are more simple than heretofore.
In order that my invention may be fully understood and readily carried into effect
I will describe the same with reference to the accompanying drawings.
Figure 1 is a front elevation partly in section of a tubular lantern constructed
according to my invention. Figure 2 is a side elevation of the same lantern, one of
the front tubes being broken away in order to more clearly shew the globe fastening,
the said globe being shewn in its opened position, and Figure 3 is a horizontal section
on the line X Y of Figure 2 shewing the clasping arms or ring for holding the globe.
A is the well or reservoir of the lamp, A' being an air chamber thereon, surrounding
the lamp burner, and All perforations therein by which atmospheric air is admitted
and mixed or combined with the rarefied air that passes down the tubes B; this
chamber A¹ is, by the tubes B, connected with the upper flanged air receiver C and
in this manner a combustion as perfect as may be is produced or effected. The air
admitted by these apertures A¹, has also the tendency to keep the flame above the
cone of the burner, during high wind, and thereby preventing the lamp from being
extinguished. D is a disc, supporting the globe, hinged at D¹ (Figure 2) to the
well A; E E are bent wires fixed and carried by the supporting disc D, which
together form the globe holder and guard, while the bent wires clasp the globe at or
near the top. F is a bent spring frame secured and depending from the air receiver C ;

page_text: this spring frame is curved as shewn at F1 and bent horizontally, in such manner as
to form two clasping arms, which when the globe G is in position partially embrace,
and hold the said globe securely.
When it is required to remove the globe G from the burner, or to open the lamp
(from the position shewn at Figure 1, to that shewn at Figure 2) for lighting or
other purposes, the glass G is pushed over and the disc D is thereby turned on the
hinge D', the clasping arms of the frame F, springing open and allowing the passage
therefrom of the globe G, which thus is caused to assume the position shewn at
Figure 2.
When the globe is returned to its normal position, it comes against the open and
divided ends of the clasping arms F, which spring open and allow the globe to pass,
and then closing again into the. form shewn at Figure 3, the said arms embrace and
hold the globe in a secure and efficient manner, as shewn at Figure 1.
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
1. In tubular lanterns, the pendant, clasping, spring-armed frame F curved at F¹
as shewn constructed, arranged, and acting substantially as and for the purposes
hereinbefore described with reference to the accompanying drawings.
2. In tubular lanterns, the general construction and arrangement of parts consisting
of the well A, chambers A¹ and C tubes B and perforations A", globe supporter D,
hinged at D¹ as shewn, together with the wire guards E E clasping the globe at or
near the top thereof, in combination with the bent and curved clasping arms F for
clasping the globe G substantially as and for the purposes herein set forth.
