PROVISIONAL SPECIFICATION.
Improvements in Lamps for Cycles and Road Vehicles.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, Managing
Directors of H. Miller and Company Limited, of Miller Street, in the City of
Birmingham, do hereby declare the nature of this invention to be as follows:-
This invention relates to lamps principally adapted for burning light volatile
oils, such as paraffin, and employed on cycles, motor carriages and other road
vehicles, and has for one of its objects, a smokeless lamp, not liable to be
extinguished by ordinary vibration, for another object, screening the reflector
and other bright interior parts of the lamps from the products of combustion of the
flame and for a further object, a new construction of lamp whose component parts
admit of being easily assembled.
The lamp consists of a shell body part or light chamber having a foot upon its
underside resting upon the top of the gallery wherethrough the hollow and circular
wick tube or casing and central air shaft up its middle axially pass, with the upper
end extending to near the mouth or. circular opening of the cone or burner located
within and made a stationary part of the body or light chamber, which is formed
from a spherical shell, having parts or sections removed to form openings for the
hinged bell or front light, the reflector, the side lights and the crown or head of
the lamp to fit within.
Thus the body, which is made from a spherical shell, has at its inside bottom, a
burner cone with a circular burner hole through its middle coming coincident with
the wick and with the walls stepped or shouldered to receive and form the rest for
a glass chimney, which extends upwardly through the middle of the body and
terminates in an upper and inner ring, having inside spring bearings and being
carried by an outer and separated ring made fast to the top of the shell body.
The space left between these said double rings is open to the atmosphere, and admits
of cooling currents passing through the body of the lamp and of the removal
therefrom of all moisture which, in ordinary lamps, dulls the glazings and polished
surfaces.
Fitted upon the aforesaid inner ring is a sleeve, with the lower edge coming upon
bridging webs connecting the said separated inner and outer rings to one another,
and with the upper end shouldered or stepped and screwed to receive the head or
external chimney consisting of a conical shaped neck, open at top and bottom, with
the latter fitting upon the aforesaid sleeve.
Closed to the top of the neck is a breaker and above the breaker comes the cowl,
separated from the said breaker by a space wherethrough the products of combustion
from the internal glass chimney outwardly pass.
By employing a screwed-on head and part external chimney screwing upon the
sleeve surmounting the body of the lamp, the said head is made detachable and the
internal chimney can be readily withdrawn from the lamp for cleaning.
The front opening in the body of the lamp, whose boundary edge is wire beaded,
has an independent reflector cone of the figure of a bell, gapped at its inside top and
bottom edges to clear the internal glass chimney and the burner cone, whilst fitted
to and hinging upon the same joint is a bezel for carrying a lens or other glazing
both cone and bezel opening independently, socketting into the beaded front opening
and fastened in commou by the same catch.!

page_text: The front of the foot of the lamp is extended and hinged to a like extended part
or annular plate of the gallery, whilst the opening in the back of the body, whose
edge is wire beaded, is closed by a hinged reflector, consisting of a hollow an
pierced back and edges with a set or shoulder formed thereon for the reception of
the edges of the silvered glass or other reflector, affixed in position by turning the
edges of the hollow or box back, wherethrough air currents may pass, over the
edges of the reflector.
The side lights consist of glazed rings with necks passed through openings in
the body sides and closed over the edges of the same.
The gallery consists of an inverted hat-shaped shell, pierced at its lower edges.
or at front and affixed to the lower part of the wick tube or casing by the lower
end having a screwed pummel and an upper shoulder up to which the pierced
bottom of the gallery comes and is there affixed by a round nut or inside screwed
collar, between which and the said bottom of the gallery a bracket plate with a
rearwardly-extending and lower hack-strap arm comes. The upper back-strap arın
is formed from a back extension of the flange at the top edge of the gallery, whilst
coming hetween the sleeved ends of the said strap arms is a back strap, formed alike
in shape to a chair bracket, fashioned from a blank of sheet metal and turne.l
staple-wise upon itself and through gaps in which, the releasing arm and catch enl
of a fastener for fixing the body to the gallery passes, whilst the standside end of
the spring rests and is secured to the inside back of the strap.
The combined oil tank and base screws upon the screwed foot of the gallery and
up to the nut or screw collar.
The body of the lamp is connected to its foot or rest by obliquely cutting its
bottom opening at a slight angle so as to cause the rays to be directed slightly
obliquely downwards instead of horizontally.
The wick casing is fitted with an ordinary winder and is circular at top, gradually
opening out to a section comprehending two thirds of a circle at the bottom, thereby
gradually converting a flat wick into a circular one.
It is understood when the body of the lamp is turned or thrown forwards on its
gallery for gaining access to the wick for lighting and trimming, the burner cone
and the whole of the cognate parts of the lamp above the burner are carried forward.
with it.
The screwed-on head or external chimney may be used in connection with the
shell or body part of an ordinary lamp for burning heavy oils, whilst the spherical
body or shell may be used with an ordinary crown and breaker, with the oil tank
connected directly to its underside instead of having a gallery coming between the
oil-tank and the light-chamber as described.
The burner cone, instead of being carried by the lamp, may be mounted on the
oil tank, and fit into a hole in the bottom of the body, and where a glass chimney
is used, it may be secured and held by a clip or rest inside the lamp.
Or the connection between the spherical body and the oil tank may be made
by screwing and the screw part may be upon the shank of the burner tube.
In such a case, the back strap, instead of being carried by the gallery, may be
carried by the tank, or by the burner or by the body of the lamp or the head or
external chimney thereof. In the latter event the bracket arms may be cranked
downwardly.
The head or external chimney may be made from three blanks of sheet metal, the
neck being formed by a cupping process, with the middle of the bottom cut out and the
other parts connected to it by closing the edges over one another. The crown is
made from a hat shaped blank, whilst the sleeve, rings and other junction parts of
the head and hudy may be made by drawing and spinning processes.
The body or light chamber is fashioned from a die-formed or spun sphere of thin
beet metal, with the top, bottom, back, front and sides sliced or segments removed
10 form openings for the bell, reflector, side lights, head and foot or base.
The foot is made from a circular stamping with a neck at the middle which is
passed through a hole in the foot of the body shell and then clenched or closed.

page_text: The gallery is formed from a cup shaped stamping with a flanged mouth.
The wick tube and air shaft may be made by part stamping and part drawing-
through processes and be put together without soldering by closing.
The oil tank is built up from two cupped stampings with their meeting edges
closed over each other, or it may be made from a single blank by a rolling process
or by spinning.
The wires of the beadings in the openings of the shell, which, when pierced,
constitutes as it were a cage for the burner, form joints for the closure parts to
turn upon.
The lamp described can be adapted for burning heavy oils as well as paraffin and
like light oils.

Improvements in Lamps Ior yores
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, Managing
Directors of H. Miller and Company Limited, of Miller Street, in the City of
Birmingham, 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 relates to lamps principally adapted for burning light volatile"
oils, such as paraffin, and employed on cycles, motor carriages and other road
vehicles, and has for one of its objects, a smokėless lamp, not liable to be extinguished'
by ordinary vibration, for another object, screening the reflector and other bright
interior parts of the lamps from the products of combustion of the flame and for a
further object, a new construction of lamp whose component parts admit of being
easily assembled.

Figure 23 is an underside plan of the foot of the lamp body which carries the
cone of the burner.
Figure 24 is a plan of the blank from which the back strap is made.
Figure 25 shows the blank from which the upper bracket-plate is made, whilst
Figure 26 is a like view of the lower bracket-plate blank.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
The lamp consists of a shell body part or light chamber a, having a foot a', upon
its underside supported from the top b', of the gallery b, wherethrough the hollow
and circular wick tube c, or casing and central air shaft c up its middle axially
pass, with their upper ends e, c, extending into the mouth or circular opening d
of the cone or burner d, located within and made a stationary part of the body
or light chamber, which is formed from a spherical shell, having parts or
sections a³, a, a, a, a, removed to form openings e, f, g, h, a', for the hinged
bell or front light e, the reflector f, the side lights g, the crown or head h, and
font a', of the lamp to fit within.
Thus the body, which is made from a spherical shell has at its inside bottom, a
burner cone d, with a circular burner hole d' through its middle coming coincident
with the wick and with the walls stepped or shouldered at d to receive and
form the rest for a glass chimney i, which extends upwardly through the middle
of the body and terminates in an upper and inner ring , having inside spring
holders or bearings and being carried by an outer and separated ring made
fast to the top a, of the shell body. A space or passage j, is left between these
rings open to the atmosphere, to admit of cooling currents passing through the
body of the lamp and of the removal therefrom of all moisture which in ordinary
lamps, dulls the glazings and polished surfaces and which currents may be utilized
also to promote the combustion of the burner flame.
Fitted upon the aforesaid inner ring is a loose sleeve or guard ring k, with its
lower edge k', overhanging and standing away from the outer ring, being separated
therefrom by an annular space, wherethrough air currents may pass into the
interior of the lamp or ascending currents may pass outwardly for ridding the
interior of moisture, and whilst the upper edge 4, rests upon a shouldered or
stepped and screwed part, of the inner ring, which also receives the head or
external chimney h, consisting of a conical shaped neck °, open at top 4, and
bottom, with the latter fitting and screwing upon the aforesaid screwed part of
the outer ring.
Closed to the top of the neck is a breaker 18, and above the breaker comes the
cowl, separated from the said breaker by a space 10, wherethrough the products
of combustion from the internal glass chimney outwardly pass.
By employing a screwed-on head and part external chimney screwing upon the
sleeve surmounting the body of the lamp, the said head is made detachable and the
internal chimney can be readily withdrawn from the lamp for cleaning.
The front opening e', in the body of the lamp, whose boundary edge e, is wire
beaded, has an independent cone e, of the figure of a bell, gapped at its inside top
and bottom edges at 3, e, to clear the internal glass chimney i, and the burner
cone d, whilst fitted to and hinging upon the same joint e, is a bezel e, for
carrying a lens e', or other glazing both cone and bezel opening independently,

page_text: socketting into the headed front opening and being fastened in common by the
same catches.
The front a, of the foot of the lamp is extended and hinged to a like extended
part or annular plate 6, carried on the gallery, whilst the opening f, in the back
of the body, whose edge f3, is wire beaded, is closed by a hinged reflector, f,
consisting of a hollow and pierced back f, and edges f, with a set or shoulder f",
formed thereon for the reception of the edges of the silvered glass or other
reflector f, affixed in position by turning the said edges f, of the hollow or box.
back, through which air currents may pass, over the edges 7, of the reflector.
The side lights g, consist of glazed rings g, with necks passed through the
openings gl in the body sides and closed over the edges of the same.
The gallery b, consists of an inverted bat-shaped shell, pierced at its lower edges
or at front and affixed to the lower part of the wick tube or casing c, by the lower
end c, of the said tube having a screwed pummel e, and an upper shoulder of up
to which the pierced bottom of the gallery comes and is there affixed by a
closing operation which at the same time secures a bracket plate m, with a
rearwardly extending and lower back-strap arm in', in position. The upper back-
strap arm m³, is formed from a back extension of the flange 6, at the top edge of
the gallery, whilst coming between the sleeved ends m³, m of the said strap arms
is a back strap me, formed alike in shape to a chair bracket, fashioned from the
blank of sheet metal shown in Figure 24 and turned staple-wise upon itself and
through gaps m, m', in which, the releasing armn n' and catch end n³, of a fastener n,
for fixing the body to the gallery passes, whilst the standside part n, of the spring
rests upon and is secured to the inside back of the strap.
The combined oil tank and base o, screws upon the screwed pummel, at the
bottom of the gallery.
The body of the lamp is connected to its foot or rest a', by obliquely cutting its
bottom opening a', at a slight angle so as to cause the rays of the light to be
directed slightly and obliquely downwards instead of horizontally.
The wick casing c, is surrounded by a pierced baffle tube p' fitted with au
ordinary winder p and is circular at top, gradually opening out to a section
comprehending two thirds of a circle at the bottom (see Figure 22) thereby
gradually converting a flat wick into a circular one.
It is understood that when the body of the lamp is turned or thrown forwards
on its gallery for gaining access to the wick for lighting and trimming, the burner
cone and the whole of the cognate parts of the lamp above the burner are carried
forward with it.
The screwed on head or external chimney h, may be used in connection with the
shell or body part of an ordinary lamp for burning heavy oils, whilst the spherical
body or shell a, may be used with an ordinary crown and breaker and the oil tank
may be connected directly to the underside of the body instead of having a gallery
coming between the oil-tank and the light-chamber as described.
The burner cone d, instead of being carried by the lamp, may be mounted on
the oil tank, and fit into a hole in the bottom of the body and where a glass
chimney is used, it may be secured and held by a clip or rest inside the lamp.
Or the connection between the spherical body a and the oil tank o, may be made
by screwing and the screw part may be upon the shank of the burner tube. In
such a case, the back strap mo, instead of being carried by the gallery, may be
carried by the tank, or by the burner or by the body of the lamp or the head or
external chimney thereof. In the latter event the bracket arms may be cranked
downwardly.
The head or external chimney may be made from three blanks of sheet metal,
the neck, being formed by a cupping process, with the middle of the bottom
cut out and the other parts connected to it by closing the edges over one another.
The crown is made from a hat shaped blank h, whilst the sleeve, rings and other
junction parts of the head and body may be made by drawing and spinning processes
(see Figure 7).

page_text: The body or light chamber is fashioned from a die-formed or spun sphere of thin
sheet metal, from which top, bottom, back, front and side segments are removed to
form openings for the bell, reflector, side lights, head and foot or base, as previously
-described (sce particularly Figures 17, 18 and 19).
The foot a', is made from a circular stamping with a neck as at the middle (sce
Figure 8) which is passed through the hole a' in the foot of the body shell and
then clenched or closed.
The gallery b, is formed from a cup shaped stamping (see Figure 8) with a
flanged mouth.
The wick tube and air shaft c, cl, may be made by part stamping and part
drawing-through processes and be put together without soldering by closing.
The oil tank o, is built up from two cupped stampings o', o, (see Figure 14) with
their meeting edges o³, closed over each other, or it may be made from a single
blank by a rolling process or by spinning.
The wires g, of the beadings g', surrounding the openings of the shell, which,
when pierced constitutes as it were a cage for the burner, form joints for the
-closure parts to turn upon; see Figures 10 and 12.
The lamp described can be adapted for burning heavy oils as well as paraffin
and like light oils.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. The improved form of lamp for cycles and road vehicles, particularly
-adapted for burning paraffin and other light oils, substantially as described and
.set forth.
Secondly. The particular method of making up the head and cognate parts of
cycle and road vehicle lamps from a series of closed together shell blanks,
substantially as described and set forth.
