Improvements in Lamps for Velocipedes and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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
This invention has especial reference to a lamp or lantern for use with a vehicle
of the bicycle class, and which is provided with a front lens for concentrating
and throwing forward the light, and with side glasses.
The
This invention has for its object the production of a lamp or lantern, of the
character mentioned, which shall be cheap in construction, neat in appearance, and
effective in operation, and shall provide a clear and smokeless flame, the light from
which shall be strongly reflected forward, and exhibited at each side.
invention also relates to means whereby the air necessary to support combustion is
effectively admitted to the buruer, thereby producing a steady flame; whereby
the products of combustion are rapidly and wholly permitted to escape; whereby
the reflector is made removable from the body of the lamp, in order that it
may be. kept burnished and bright; and to other details of construction, herein
described, whereby the general character of lamps or lanterns of this class is
improved.
In the accompanying drawings,
Fig. 1 is an exterior view of a lamp or lantern embodying my invention. Fig. 2
is a,vertical section thereof.
Fig. 3 is a horizontal section on the line - of Fig. 2.
Figs. 4, 5, 6 and 7 represent detached details.
Similar numerals of reference indicate similar parts in the respective figures.
.1 is the outer case of the lamp, which, as here shown, is in the main spherical in
form, although it may be otherwise shaped. At the front of the case is an outwardly
flaring tube or support 2, the interior surface of which is highly burnished. The
ring 4, supporting or framing the front lens 3, is hinged to the outer part of the
tube or support 2, and carries a spring catch 5, guarded and guided by a staple 6,
which catch, when the ring 4 is closed down upon or against the tube or support 2,
springs or snaps over a shoulder or projection 7, formed thereon, thus holding
the framed lens in a closed position. The part of the ring 4 in which the lens 3
is immediately placed, is divided or split, the separated ends being provided with
lugs 8, 9, the latter of which is threaded and serves as a nut for a screw 10, the
action being such that, by tightening the screw, the ring is caused to bind the
lens and maintain it securely in place. It is also obvious that the ring may be
loosened upon the lens, should occasion require this to be done. The flaring
tube or support 2 is detachably secured to the outer case 1 by means of a
threaded ring, attached to the tube, engaging with a similarly threaded ring
secured to the front opening in the case,

page_text: At each side of the outer case'l, and preferably in the central horizontal plane
of the lamp, are the side signals 11, 12, consisting of colored glasses or jewels 13°
and 14, framed as hereinafter described. The glass 13 is mounted in an annular
frame 15, which is hinged to a tapering thimble 16, provided with a threaded
portion which screws into a neck or ring 16 secured to the outer case. The
exterior part of the thimble projects slightly beyond the outer surface of the case 1,
in such wise that the framed glass or jewel 13 may be swung or turned upon its
hinge 17, so as to permit access to the interior of the case for the insertion of a
lighted match. The frame of the glass 13 is maintained in its closed position by
means of a metallic clip 18, into which a portion of the flanged edge of the annular
frame 15 fits, when occupying its normal position. The opposite signaling glass 14
is mounted in a frame 19, attached to which is a tapering thimble 20, having
a threaded portion which screws into a threaded neck or ring 21, slightly
projecting from the outer case. Other functions of the tapering thimbles. 16
and 20 will be hereinafter pointed out. These two thimbles may be alike, and
with or without the hinge.
The rear portion of the outer case 1 is cut away and the interior of the opening
is widened and threaded, as shown at 22. Within the threaded opening a frusto-
conical body 23, the inner side of which is slightly concave and highly burnished,
so as to constitute a reflector, is screwed, the outer portion of the said body being
flanged and having a milled edge 24, whereby it may be readily screwed to and
unscrewed from the outer case 1.
The upper portion of the outer case 1 is provided with a flanged ring 25, in the
mouth of which rests a conical wind cone or deflector 26, supported by feet or
standards 27; while at the top of the part 28 of the said cone or deflector, is
secured a cap 29. At the base of the ring 25, are a series of perforations 30.
The lower portion of the outer case. 1 is in the form of a cylindrical neck 31,
into which the upper part of the oil receptacle 32 fits, the said receptacle, when
in place, forming the base of the entire structure. The neck 31 is provided, at
opposite sides, with vertical slots 33, terminating in horizontal slots 34, while the
upper portion of the oil receptacle is furnished with projecting pins 33, 34,
which, in connection with said slots 33, 34, upite the oil receptacle 32 and case 1
by bayonet joints, as will be readily understood. A plate spring 35 partially
surrounds the neck 31 of the outer case, the outer end of the spring being provided
with a hole 36 and an outwardly turned finger part 37, the hole 36, when the attach-
ment between the oil receptacle and the case is effected, fitting over the pin 33, and
securing the parts together. The outward movement of the spring 35 is limited
by means of a wire guard 38. The oil receptacle is of any ordinary or approved
construction, and the shaft 40 of its wick-raiser extends beyond the outer case 1,
the neck or ring 31 being furnished with a slot 41, in which the said shaft rests,
and which allows its passage when the oil receptacle is to be moved downward for
detachment from the case.
Within the outer case 1, is a metallic chimney 42, Fig. 4, the enlarged lower
portion of which is provided with four openings for purposes to be described. The
lower edge of the metallic chimney 42 rests upon the gallery 43 of the burner, so
that the row of perforations 44 in said gallery is just within the base of the
chimney; and at or near the base of the said chimney is also a row of
perforations 45, they having the obvious function of admitting air to the flame.
The upper part of the chimney 42 passes up into the interior of the cone or
deflector 26..
The inner portion of the conical tube or support 2 for the lens 3, fits in the front
opening of the metallic chimney 42; while the inner portion of the frusto-conical
body 23, Fig. 5, as a part of which the reflector is formed, fits in the corresponding
rear opening of the chimney. The two smaller openings of the metallic chimney
receive the tapering thimbles 16 and 20, Fig. 6, of the respective side or signaling
glasses. By this construction, tight, yet readily detachable, joints are made

page_text: between the front and side lenses, and the reflector, respectively, and the metallic
chimney; which chimney serves.not only to carry away the products of: combustion
from the flame, but also to concentrate and confine the light, so as to cause it to be
effectively thrown through the front and side lenses.
It will be seen that the reflector is readily removable from the outer case-and
metallic chimney, and that .it, therefore, may be conveniently kept clean and
burnished; and also that the supports of the front and side, lenses may be easily
removed from the outer case and metallic chimney, so as to release the latter and
enable it to be removed.
:
The lamp or lantern is provided with a spring support 47 of any ordinary or
approved construction.
An important feature in my.invention is the metallic chimney 42, cut away to
receive the lens supports and the inner-end of the body or support carrying the
removable reflector. The arrangement of the air openings, and of the cone or
deflector and cap, and the.carrying of the metallic chimney into the upper portion
of the lamp case, and near.the point. or exit of the products of combustion, are also
important. By the construction herein described, the lamp may be readily taken
apart, even by persons unskilled in mechanical methods, for the purpose of
inspecting or cleaning any of its parts, and as easily put together again. This may
be done without unnecessarily soiling the hands, inasmuch as the exterior of the
chimney and the interior of the outer case cannot be reached by soot or smoke, all
the products of combustion being carried off without the possibility of reaching the.
said surfaces of the parts named, or the supports for the lenses, or the reflector, or
other parts which the user may wish to handle.
"
It is obvious that deviations may be made from my lamp or lantern, as here
described, in minor features, not involving invention. Thus, while I have described,
and prefer, a metallic or opaque chimney, one of glass, or other material, might be
substituted. It is also evident that the supports for the lenses might be. attached
to the outer case in a manner other than by threaded joints, as also might the
reflector, provided it were still made removable. The means of attaching the
lantern case to the oil receptacle may be varied; the arrangement of the air
apertures changed; and other details of construction altered, at the discretion of
the skilled mechanic. The outer case is preferably spuu, as also are the metallic
chimney and other parts; but other modes of construction thereof, and changes in
their shapes,:may be made.
