Improvements in Bicycle Lamps.
We, ERNEST DAYTON TERRY, of 215 Centre Street, in the City of New
York, County and State of New York, U.S.A., Manufacturer, and JAMES
FRANK PLACE, of 215 Centre Street, in the City of New York, County and
State of New York, U.S.A., Manufacturer, 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 :-
The object of this invention is to supply a steady volume of air to the burner,
without the flame being affected by outside wind currents to keep the lamp cool,
and to furnish a handy, yet positive, mechanism for fastening the lamp to the
vehicle or bicycle; and to so connect the lamp-body and oil reservoir together
that they can be quickly put together or disconnected.
Referring to the drawings:-
Fig. 1 is a longitudinal sectional view of the lamp or lantern complete when
fixed to a bicycle, showing the improvements;
Fig. 2 is a longitudinal sectional view of the improved clamp attached to the
handle, showing its position when not fixed to a vehicle, or bicycle;
Fig. 3 is a top plan view, partly in section, of the improved air supply
perforated annular disc below the burner, which also serves as the bottom to the
new burner gallery;
Fig. 4 is an elevation (outside view) of part of the lamp showing where the
burner shank comes through the lamp-body in the joint where joined to the oil
reservoir; also one of the lugs or legs, with wind-guard flange or skirt above the
same on lower part of the gallery ring, which protects the air inlet holes from wind
currents.
The following is a detailed description of the improved lamp or lantern.
Referring to reference marks:-
1 is the lamp-body; 2 is the oil reservoir or fount; 3 is the burner; 4 is the
canopy top or smoke-stack; 5 is the lens; 6 is the handle, which is connected to
the lamp-body by the bracket 7. All of the parts thus far designated may be made
as shown, or of any ordinary design of lamp or lantern for outdoor use.
To the top of the oil fount is fixed a gallery ring S, the lower side of which ends
in three legs or lugs 9, two of which are shown in Fig. 1 and the third one in
Fig. 4. These legs are passed through the top of the oil fount, and rivetted or
clinched at 9'. Within this gallery ring 8 resting on the shoulder 10 is fixed a
perforated annular disc 11, which also forms the bottom of the gallery ring, below
the burner. This disc has a raised annular portion 12; and in and around the
sides of this annular raised part is one or more rings or circles of holes, 13 and 13',
which pass in through the disc horizontally to the inside of the lamp-body, below
the burner.
The are
It will be noticed that the ring 8 has around it a flange or skirt at 14 between
the top of the legs 9 and the shoulder 10. This is for the purpose of breaking any
wind-currents and protecting the holes 13 and 13' from such currents.
passing in under the wind-guard 14 circulates around the lugs 9 and over the top
of the oil reservoir 2, thus absorbing the heat of the same, and keeping the oil in
the font 2 cool. The air to supply the burner passes up into the annular raised
part 12, and is drawn through the series of horizontal holes 13 and 13', and strikes

page_text: the inside of the ring & and the outside of the burner 3 in a large number of
horizontal jets, thus taking up the heat of those parts. The force of the air-
currents is also much broken, as there is an outward current of air against the
inside of the ring 8, and an inward current of air against the burner 3 or its base,
so that the air as it takes an upward direction and rises to the burner, it is delivered
evenly and without sufficient force to affect the flame. The air which passes
through the holes 15 in the back of the lamp-body is deflected from the flame by
the reflector 16.
To the handle G is attached the clamp 17, which has a lever or cam 18. The
bracket usually attached to a vehicle or bicycle is shown at 19. Within the clamp
is a rubber cushion 20, which surrounds the lamp bracket 19; and also within the
clamp is a movable steel plate 21, which is held firmly by the rubber cushion 20,
against the end of the cani or lever 18. This can is firmly pivoted or held to the
clamp by the pin 22.
In Fig. 2, the lever or cam is shown in its normal position when the lamp is not
fixed to the bicycle. In that position the rubber cushion presses the steel plate 21
back against the wall of the clamp, and allows the bracket 19 to be easily inserted
between the two folds of the rubber cushion. By pressing down the lower end of
the cam or lever 15, the short or cam end at 23 forces the steel plate 21 inwardly
against the rubber cushion, and the bracket 19 is firmly gripped between the folds
of the rubber cushion, as shown in Fig. 1, so that the lamp or lantern cannot be
removed from the bracket until the lever 18 is raisedl, as shown in Fig. 2.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a vehicle or bicycle lamp or lantern, a burner gallery ring, having a disc
or bottom below the burner, with an annular raised portion, around and in which
are one or more rings of horizontal air inlet holes, substantially as described.
2. In a bicycle lamp or lantern, the combination of a burner gallery having hugs or
legs, and a flange or wind-guard above the same, and around said gallery, with a
disc forming the bottom of said gallery below the burner, said disc having a raised
annular portion, and one or more rings or circles of horizontal air-inlet holes in
said raised annular part, substantially as described.
3. The combination of a bicycle lamp or lantern with a clamp and handle
attached to the same, a fixed bracket attached to a vehicle or bicycle, a movable steel
plate in said clamp held in place by a rubber cushion; and a cam or lever operating
against said steel plate-whereby said plate is moved forward and is made to grip said
bracket by the operation of said cam or lever, substantially as described.
4. In a bicycle lamp or lantern, the combination of a clamp consisting of a cam
or lever and movable steel plate held against a rubber cushion and operated by said
cam or lever; a burner and burner gallery ring with legs or lugs counerted to an
oil reservoir; a wind guard or flange around the lower side of said gallery ring; a
disc or bottom to said ring; a raised annular part in said disc or bottom below the
burner, having one or more series of horizontal air inlet holes therein, substantially
ns described.
5. In a bicycle lamp or lantern, the clamp 17, having the cam or lever 18, the
rubber cushion 20 and the movable steel plate 21, substantially as described.
G. In a bicycle lamp or lantern the gallery ring 8, with disc or bottom 11, the
legs or lugs 9, the wind-guard or Hange 14, the raised annular part 12, the said dise
or bottom, having the horizontal air inlet holes 13 and 13' below the burner, for
the purpose substantially as described.
7. In a bicycle lamp or lantern, the combination with lamp-body burner, lens,
reflector, handle, and oil reservoir, with a clamp consisting of a cam or lever, a
rubber cushion and a movable steel plate operated by said cam or lever; and a
burner gallery having a disc or bottom with a raised annular part below the burner,
and horizontal air inlet holes in and around said raised annular part, said burner

page_text: gallery having legs or lugs on the lower side, and a flange or wind-guard between
said disc or bottom and said lugs or legs, all substantially as described.
