I, CHARLES MURRY BUMP, of Bay City, Michigan, United States of America,
Banker, 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 improvements in bicycle lanterns, and has for its object
to produce a bicycle lantern with the burner telescoped into the oil receptacle and
supported by a coiled spring, so arranged that the burner will oscillate and avoid
sudden shocks or jars from extinguishing the light, when the bicycle comes in contact
with rough or ridgy obstacles.
A further object of the invention is to construct a bicycle lantern that may be
rigidly secured to the bicycle frame or tubing with the object of avoiding it from
swinging or swaying about when the bicycle is in motion, to avoid additional
disturbing of the light by the air rushing to and fro thereby.
A further object of the invention is to construct a bicycle lantern that will be
adapted to burn either heavy or light grades of hydrocarbon oils.
A further object of the invention is to construct a bicycle lantern which will be
easily and conveniently secured to any desired part of the bicycle frame, and at the
same time simple and cheap in its design and manufacture.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar letters of reference indicate corresponding parts in
all of the illustrations.
Fig. 1, represents an exterior view of a bicycle lantern embodying my
invention.
And
Fig. 2, is a vertical central section taken on the line X, X, Fig. 1,
Fig. 3, is the oil receptacle. And
Fig. 4, is the burner.
Fig. 5, is an upper cushioning spring for the burner, and Fig. 6, is a supporting
spring for the same.
Fig. 7, is the supporting clamp for the lantern.
A is the oil receptacle, and B is its opening within, C is the supporting clamps,
D is the burner, and E is its opening within, F is the coiled spring which supports
the burner, and G is the coiled spring for cushioning the same, H is the wick and
I is the globe which is provided with perforated openings as shown at V, V, for
the admission of air therein, and perforated exit openings as shown at W, W, for
the purpose of permitting the gases to escape, the bulls eye Y, and the inner
projecting flange M, provided in the lower contracted eud for a purpose to be
presently explained.
The oil receptacle A, is provided with an upwardly extending tube J, which is
provided with an opening K, therein, which forms an opening in the upper side, of
the receptacle A, thereby, the coiled spring F, is placed concentric with the
tube J, and rests upon the said oil receptacle A, which provides an elastic spring
thereon.
The burner D, is provided with an upwardly extending tube which is provided with
an outward projecting flange L, near its mid way also a wick manipulating device P,
which serves to support the wick H, when burning the lighter grades of hydrocarbon

page_text: oils, such as naphtha benzine or gasoline, and when burning the heavier grades of
hydrocarbon oils the wick H may be manipulated by the same.
The lower extended end of the burner D, is telescoped into the opening K, of
the tube J, with its outward extending flange L, resting upon the coiled spring F,
and is supported thereby.
The upper cushioning spring G, is placed upon the outward projecting flange L,
which provides its support thereby, and receives its tension and is held in position
by means of the inner projecting flange M, resting thereon, at the proper height
to serve for the same, whereby means is provided for the burner to cushion on its
upward motion, and thumping and jarring is avoided thereby.
The globe I is provided with a bayonet slot O on its lower end, for the purpose
of securing it to the oil receptacle A, by means of the pin N, provided thereon, at
a suitable height to admit of the inner projecting flange M, to produce the proper
tension upon the cushioning spring G.
The supporting clamp C, is composed of a body Q, which is provided with two
extended curved arms R, R, journaled thereto at S, S, and a threaded thumb
screw T, provided in their extended ends, the body Q, is secured to the side of the
oil receptacle A, by any suitable means at U. The clamp R, R, is placed astride
of the desired portion of the bicycle tubing or frame and is secured thereto, by means
of drawing the clamps R, R. together by the said thumb screw T, which rigidly
secures the lantern thereon.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
'claim is :-
1st. A bicycle lantern comprising a coiled spring F, the burner D, provided with
the flange L, said flange placed upon the said coiled spring and the said burner
supported thereby substantially as described.
2nd. A bicycle lantern comprising a burner provided with an extended flange
near its midway and the means for supporting the wick, the lower supporting
spring F, the upper cushioning spring G and the globe I provided with the inward
projecting flange M, the said extended flange placed upon the said spring and supported
thereby, the said cushioning spring placed upon the said extended flange and held
in position by means of the said inward projecting flange provided in the said globe
substantially as described.
3rd. A bicycle lantern comprising an oil receptacle A, provided with an upwardly
projecting tube J, and forming an opening therein, the supporting spring F, the
burner D, the cushioning spring G, and the globe I, the said supporting spring
placed upon the said oil receptacle and concentric with the said tube, the lower
end of the said burner telescoped into the said tube and oil receptacle, with
its extended flange L, resting upon the said supporting spring and supported
thereby, the said cushioning spring placed upon the said flange and held in position
by means of the inward projecting flange M, of the globe I; substantially as
described.
4th. In a bicycle lantern, comprising of an oil receptacle A, with an upper
extended tube J, which forms an opening therein, the pin N, and the clamping
device C, in combination with the globe I, provided with the bayonet slot O, at its
lower end and the inner projecting flange M, the said globe telescoped over the
said oil receptacle and supported by the said bayonet slot locking over the said
pin, combined with the supporting spring F, the burner D, and the cushioning
spring G, all said parts combined substantially as described.
