Improvements in Cycle Lamps.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, trading as
H. Miller and Company, of Miller Street Aston, near the City of Birmingham
Manufacturers do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of a two-part section lamp, or a lamp
composed primarily of two parts, hinged together in such a manner that the main
body part moves away from the other and fixed part, to admit of the interior of the
lamp being more readily got at, for cleaning the said interior, trimming the wick,
and the like.
Thus, in our said invention, the main shell body part, which has an open back
and bottom, belled front, and top, comprehending hood, crown and breaker, is
jointed to, and suspended or hung from, or near the top of a fixed back, directed
upwardly from the rear of the oil tank, which forms the base.
The lamp primary parts consists of a movable body, hinged at its upper and
back end to the upper end of a fixed back.
The
In carrying out our invention, we take a skeleton body part, comprehending two
sides, a top, and a belled front. The bottom is open, likewise is the rear.
fixed part comprehends a hollow base, forming the oil tank, with a rigid back or
upright plate, which carries or is made into a reflector upon its inner side, and
with sleeve or joint attachments, for the connection of the supporting arms on its
outer side.
The upper part of the back of the shell body part is horizontally jointed to the
top of the back, which latter, forms as it were, an upright bracket, for the hanging
or supporting of the said shell body part, which moves upon its joint in a vertical
plane.
We prefer that the jointing should be at the junction of the shell body part with
the crown.
Normally, the bottoms of the shell body part sides come upon the top side of the
base or tank, and with the inner side boundary edges rabated or flanged, which
when in position, lie behind slightly returned edges of the back, so as to make a
closely fitting joint.
To give rigidity or stay, the underside of the bell may have a dowel or projection,
which takes into a hole or depression within the front of the oil tank, and forms a
guide to the proper closing.
Instead of this form of guide, the top of the oil tank may be channelled, wherein
the opposed bottoms of the sides of the shell body part take, and are thereby
guided into position.
A spring catch fixes the movable part to the fixed part.
When closed, the lamp has the appearance of an ordinary lamp, but on the shell
body part being unfastened, the same admits of being swung outwardly and
upwardly, until the bottoms of the sides of the shell body part are presented upper-
most, or nearly so, and with the whole of the fixed back part and base left exposed
or made perfectly open on all sides.
By mounting and arranging a swing body part with a tank base having a bracket
back, the interior of the said lamp is made very accesible.
Instead of the back of the lamp being made in the form of a bracket, and a
fixture with the tank or base, the belled front may be made the fixed bracket, and
with the shell body part jointed at its front upper part to the top of the fixed part
constituting the front.

the same to clear the burner on the said body part, from the base.
Or the shell body part of the lamp may be jointedly connected at its front lower
part to the offside top end of the front of the tank, and away from the bracket back,
which carry the suspension arms, so that the back, when the shell body part is
brought vertical, forms a closure.

COMPLETE SPECIFICATION.
Improvements in Cycle Lamps.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, trading as
H. Miller and Company, of Miller Street, Aston, near the City of Birmingham,
Manufacturers, 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 improvements in the construction of two-part-sectional
lamps, and our said invention consists in jointing the said sectional parts together
in manner, that the body part or the main body part moves away froin another and
fixed part, when a lamp is opened.
By thus bodily turning away the said first named part from that of the said
second named part, the interior parts of a lamp are exposed, more readily got at for
cleaning, and other purposes, than has heretofore been accomplished.
Thus in our said invention, the main shell body part, which has an open back and
bottom, belled front, and top, comprehending hood, crown and breaker, is jointed to,
and suspended or jointedly hung from, or near to the top of a fixed and erect back,
directed upwardly from the rear topside of the oil tank, which forms the base or
bottom.
In carrying out our invention, we take a skeleton body part, comprehending two
closed sides, a semi closed top, and a glazed front. The bottom and rear parts of
the movable body part are open. The fixed part comprehends a hollow base,
forming the oil tank, with a rigid back or upright plate, which carries or is made
into a reflector upon its inner side, and with sleeve or joint attachments, for the
connection of the supporting carrying arms on its outer side.
The upper part of the back of the shell body part is horizontally jointed to the
top of the back, which latter forms, as it were, an upright bracket, for the hanging
or supporting of the said shell body part, which moves upon its joint in a vertical
plane.
We prefer that the jointing should be at the junction of the shell body part, with
its crown.
Normally, the bottoms of the shell body part sides, come upon the topside of the
base or tank, and with the inner side boundary edges rabated or flanged, which when
in position, lic behind slightly returned edges of the back, so as to make a closely
fitting joint.
To prevent deflection of the back, and to give rigidity or stay thereto, the under-
side of the bell or the body of the lamp may have a stay, dowel or projection, which
takes into a hole or depression within the front of the oil tank, and forms a stay tie
and guide to the proper closing. Instead of this form of guide, the top of the oil
tank may be channelled, wherein the opposed bottoms of the sides of the shell body
part, take and are thereby guided into position.
A spring catch fixes the movable part to the fixed part.
When closed the lamp has the appearance of an ordinary lamp, but on the shell

page_text: body part being unfastened, the same admits of being swung outwardly and
upwardly, until the bottoms of the sides of the shell body part are presented upper-
most, or nearly so, and with the whole of the fixed back part and base left exposed,
or made perfectly open on all sides.
By mounting and arranging a swing body part with a tank base having a bracket
back, the interior of the said lamp is inade very accessible.
Instead of the back of the lamp being made in the form of a bracket, and a
fixture with the tank or base the belled front may be made the fixed bracket, and
with the shell body part jointed at its front upper part to the top of the fixed part
constituting the front.
Or the shell body part may be connected to the fixed part by a link, so as to lift
the same to clear the burner on the said body part from the base.
Figure 1 of the accompanying drawings represents in side elevation, partly in
section, a two part jointed sectional lamp constructed, arranged and provided with
improvements made according to our invention. The said figure represents the
lamp closed, or the component sectional parts in the positions which they assume
when the lamp is in use..
Figure 2 represents in section with parts in elevation the lamp open, or the
movable and shell body part turned forwardly from the fixed back, and upwardly
from the base, which latter component parts remain quiescent, and have connected
to them, the bracket or other arms employed in mounting the lamp.
Figure 3 represents the sectional component parts separated, showing the joints
at the upper ends or parts of both of them.
Figure 4 is an underside plan of the shell body part of the lamp separately.
Figure 5 represents a front elevation of the lamp when the same is fully opened,
or with the jointed and shell body part turned back so as to come practically into
the same plane as the fixed back upon which it is hung thus making accessible and
exposing the whole of the interior surfaces and parts of the lamp.
In Figures 1 to 5, a is the shell body part, having an open or unenclosed
bottom, and also an open or unenclosed back a³; a' is the closed or solid front,
carrying a glazed bell as, with light aperture a, through it. a' are enclosed sides.
The upper part of the said shell body part a, has a crown a', a hood a³, and a
breaker a, and with the upper part of the said open back, at its junction with
breaker, hood and crown, jointed or hinged at b, to the top or extremity of an
upright and rigid back c, directed from or carried upon the topside rear part of an
oil tank d, which forms the base or bottom to the lamp, when the opened or unenclosed
bottom and back body part is closed.
Jointedly connected to the middle of the outer side of the fixed back of the
lamp are bracket arms e, having or carrying at their extremities, a socket plate
or socket f', f.
The said mounting is connected to the back of the lamp by a hollow ventilated
backstrap g, or other means.
The lower extremities of the sides a¹, at the open bottom a³, fit upon rabated
edges, of the slightly raised top of the oil tank, hence the making of the joints
practically light and weather tight when the said body or dislocated body part is
closed, and also makes the whole of the parts rigid.
The fixed back carries an attachable and detachable reflector h, so that when the
dislocated body part of the lamp is swung upon its hinge joint, and the whole of
the interior of the lamp of both the fixed or movable parts exposed, the attachable
interior parts can be removed, or the whole cleaned, and the wick lighted
trimmed. One of the sides a', of the lamp body part is gapped at a for the
clearance of the wick winder as, and which clearance a¹, is covered over when the
lamp is closed, by a closure plate a¹.
OĽ
Fitted to the underside of the front of the lamp is an outstanding plate i, carrying
an inwardly disposed inclined lip, stay dowel or projection, which is adapted to
take a bearing upon the shoulder or inclined top part d', of the mouth entrance d',

page_text: of a hole or recess d³, wherein the tongue spring catch j, works, and is adapted to
engage with or snap behind the plate i, as aforesaid.
The fully closing of the movable and hinged body upon its base causes the slightly
inclined lip or dowel, to impinge or bear upon the shoulder or top part d', of the
month d, and by such impingement, the fixed back is prevented from being deflected
or forced out of the perpendicular by the force applied in fastening the movable part
of the lamp to the fixed part.
Thus by causing a projection or dowel part carried by the movable part of the
lamp to take and bear upon a fixed part of the base, the said movable part of the
lamp is stayed or tied in manner so as to preserve a constant or fixed distance
between the joint and its base.
Thus it is obvious that unless such means of diagonal tying, as it were, the lamp
movable part to the base during the fastening, were employed, the upright back
would be immediately forced out of the perpendicular, in consequence of the
members forming as it were levers forcing against each other, by the hinged point
of support of the upright back being so considerably removed from the base.
In the base part, is a tongue stop, for limiting the movement of the said free
tongue catch j. It will be seen that the opposite edges of the perpendicular back
are provided with inwardly directed flanges, which when the lamp is closed, fit over
the rabated back edges a¹³, of the open back a³, of the body a, hence the making of
the same both weather and light tight and rigid.
We wish it to be understood that instead of the tank being employed as the base
to the lamp, we may employ a base or bottom with slightly turned up edges, and
enclosed within the sides or resting upon the base or bottom, a loose oil tank may
be fitted, either to slide therein, or be otherwise attachedly connected.
Figure 6 represents a side elevation, partly in section, of a cycle lamp constructed
and mounted according to a further form of our invention, the said lamp being
shown closed.
In this arrangement, the dislocated and shell body part, which is open or
unenclosed at front and bottom, is hinged at its front upper part to the extremity
of a fixed front which carries the bell or glazed light aperture.
Figure 7 shows the said lamp, which is in section, open or partly open.
Figure 8 represents the primary and dislocating parts of the lamp detached.
In Figures 6, 7 and 8, a is the shell body part of the lamp, with open bottom a²,
and open front a³, closed sides and back a, a, and semi-open top a', a and a, and
with the upper part of the open front a³, jointedly connected to the upper end of the
upright fixed part e, carried by the oil tank d, by a joint . This said front part
carries the glazed bell or light aperture passage a¹.
i, is the plate stay and dowel tie for staying the lamp or the front of the lamp,
when pressure is applied for closing and fastening as aforesaid.
The bracket arms for the mounting of the lamp are in this case carried at the
back of the shell body part, instead of, as in the former arrangement, the same
being carried at the rear of the fixed back.
The lamp is fitted with reflector and the like.
Instead of employing the tank d to constitute the base, we may employ a fixed
bottom, made to receive or take an oil tank.
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: A cycle lamp, composed of two primary and sectional parts, one part
consisting of a hood-shaped body part, or a shell body part, having complete sides,
and open or unenclosed at both back and bottom, and the other part consisting of a
fixed back, bracket, upright, plate, or their equivalents, mounted upon and carried
by an oil tank base or bottom, or a base or bottom not integral with an oil tank,
and with the upper part of the first named sectional part, jointedly connected to, or

page_text: pivotedly hung, swung or mounted from or upon the top or upper portion of the
said second named back sectional part, substantially as set forth in Figures 1 to 5.
Secondly-A cycle lamp, composed of two primary and sectional parts, the one
part hinged or jointedly hung from the top or upper part of the other sectional
part, substantially as described and set forth in Figures 6, 7 and 8.
Thirdly-In two-part sectional and hinged together cycle lamps, staying or
tying the one part, or the sectional body part, to the other or base part, by a
dowel, lip or projection upon the one part, engaging with, or bearing upon, a
shoulder, or taking within a recess, of the other part, upon the fully closing of the
one sectional part upon the other sectional part, whereby the back upright or
bracket of the one sectional part, (upon which the other sectional part is hung) is
relieved from undue strain, and the perpendicular of the said upright part preserved,
substantially as described and set forth.
Fourthly In cycle two-part sectional and hinged together cycle lamps, the
construction, arrangement and combination of the parts substantially as described
and set forth.
