Improvements in the Manufacture of Lanterns, Hand Lamps, and
other Analogous Articles.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, Managing Directors
of H. Miller and Company Limited, of Miller Street, in the City of Birmingham,
Cycle Accessory Manufacturers, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the manufacture of hand and other lanterns, cart
and other lamps and analogous lanterns and lamps for various uses, and particu-
larly of that type in which the body is made up of a frame having glazed sides
closed at top and bottom.
The primary object of this invention is the making of the principal parts of
the said lanterns and lamps without soldering.
We will describe our invention in connection with a cart, hand or lantern
lamp, having a rectangular shaped body with glazed sides, a hinged door and
closed, or partially closed at top and bottom.
The bottom of the lamp consists of a square plate of sheet metal, with a turned
under beading at its back edge and a turned up deep flange at its front side with
the top edge of the said flange shaped to form a part of the front frame. The
top edges of the opposite sides of this bottom plate are turned inwards and over
into the figure of the letter U, thus forming horizontal edging channels, which
when closed upon right angle, flanges of two frames forming the sides of the
body of the lantern, the said frames are affixed to the said bottom without solder-
ing.
The said sides forming the body of the lamp are each formed from a cut out
middle pierced blank, with outwardly directed right angle flanges at its lower
and top edgings and with an inward right angle flange at its front edging.
The back edge of one side has the metal turned back upon itself with the
extreme edging cranked outwardly into a groove or channel, and with a hollow
beading coming and running about midway down the said turned back part,
through which the pinning up wire to form the joint, for the catch, passes. A
gap is also cut in the edge of the side through which access to the interior of
lantern is gained for light by a match.
The back edges of the other side is alike unto the first named side, but left open
in the earlier stages of manufacture for receiving the pinning up wire which
forms the joint to the hinge. This turned back edging has separated gaps
for receiving the knuckle of the door and through the eyes of which said knuckle
the wire passes. On the wire being placed in position, the open turned back
edging is then closed and the joint wire thereby affixed and the knuckles kept
in place.
The sheet metal at the edgings of the door is turned back to reinforce the same.
The crown or breaker 9s formed from a centrally pierced blank of sheet metal
with turned under channels or horizontal grooves which take upon the right

page_text: angle flanges at the top edges of the sides, and are then closed by pressure, thereby
affixing the said top to sides, without soldering.
The curved breaker is made from a piece of sheet metal bent into a convex
figure and affixed to the pierced crown by ears of it engaging with piercings of
the other part and then clenched.
The extreme top or roof which is a covering to the crown and breaker, is made
from a blank of sheet metal, bent into an arched figure with crossed creased
sinkings or deep channels formed near the ends of the blank and shaped to agree
with, and form part of the sides at the tops of the frame. These channels engage
with, and are closed upon the top-edge-flanges of a pair of top cross strips or
straps connected to, and bracing the tops of the sides constituting the body frame,
and moreover these extended ends of this top plate are bent down at right angles.
and directed into the same plane as the sides, and are there secured.
The tops of the sides, which are two in number only, make up the body frame
and are braced together in right angle directions, by the top plates as aforesaid.
The glazings may be set in separate frames, attached to, or soldered to the
sides as aforesaid.
The bottom may be open at the middle or it may be closed.
The sides may be parallel or may be relatively taper, so as to form a lantern
with taper sides.
Instead of the flanges being on the frame elements they may be on the bottom
and top elements, and channels formed or sunken in the side elements.
The application of our invention to other lanterns and lamps, differs in no
essential respect to a hand lantern as described.

Improvements in the Manufacture of Lanterns, Hand Lamps, and
other Analogous Articles.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, Managing Directors
of H. Miller and Company Limited, of Miller Street, in the City of Birmingham,
Cycle Accessories 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 the manufacture of hand and other lanterns, carb
and other lamps, and analogous lamps and lanterns for various uses, and particu-
larly of that type in which the body of the article is made up of a frame having
glazed sides. The principal object of the invention is to provide for the assembl-
ing or making up of the principal parts of a lantern without soldering, whereby
the cost of manufacture is materially reduced.
We will describe our improvements as applied to the construction of a cart
hand lamp or lantern as represented in the drawings hereto annexed, and com-
prising a rectangular shaped body part with glazed sides and front, a hinged
bor at the back, a closed bottom and a partially closed top provided with a
breaker and a cowl or roof.

The same letters of reference indicate corresponding parts in the several figures
of the drawings.
The bottom a (Figures 20, 21 and 22) of the lamp consists of a square or
rectangular plate of sheet metal, preferably having a turned under beading a¹,
along its back edge, and a turned-up deep flange a', at its front side, with the
top edge of the said flange shaped so as to form the bottom part of the glazed
front of the lamp. The metal at the opposite sides of this bottom plate, which
forms the foundation to the structure, are turned inwards and over to form
U-shaped edgings a, a³, which constitute horizontal grooves or channels adapted
to receive and be closed down upon right angle flanges c, d, formed along the
bottom edges of the opposite side frames c (shown separately in Figures 14, 15
and 16) and (see Figures 17, 18 and 19) and so secure the said sides to the
bottom of the lamp without soldering.
The said side sections are each formed from a cut-out middle-pierced blank,
respectively having outwardly directed flanges c¹, e², and d¹, d², at their bottom
and top edgings and inwardly-turned right-angled flanges c, d, at the front
edgings.
The back edge of the right hand side section (Figures 14, 15 and 16) has the

page_text: metal turned back upon itself at c, and the extreme edge of the turned back part
is cranked inwardly at e, to form a vertical groove or channel 6, whilst a hollow
beading e, is also formed in the said folded edging adapted to receive a wire c8,
a part of which is exposed by cutting a gap in the metal at c, and forms the
joint for the catch or fastening i, of the hinged door e. A clearance may also
be made at , through which the wick-winder stem of the burner may pass to
the exterior of the lamp.
The back edge of the other and left hand side section is formed like that of the
right side with a turned back part d, eranked part, forming a vertical
channel, and hollow beading, to receive a pinning up or joint wire d
which is exposed by forming in the said edging a pair of separated gaps
adapted to receive the joint knuckles of the door, through which knuckles the
wire 8, is passed at a suitable stage in the manufacture, and to facilitate this
the edging may be left open or enclosed during the earlier stages, but after the
said wire has been placed in position, the said edging is closed down, thereby
securing the joint wire and keeping the knuckles of the door in place within the
gaps provided for their reception. The beading and channelling of the rear edges
of the sides in manner as described add considerably to the strength of the framing
when assembled.
The door e (shown separately in Figures 23, 24 and 25) at the back of the
lamp is cut out from sheet metal and the bottom and top edges are turned over and
inwardly at e, e², to reinforce the same, whilst the metal at the sides is preferably
turned inwards into flanges e³, e, adapted to overlap the respective back corner-
edgings. The joint knuckles may be attached by soldering to the inside of
the said back, which may be perforated at e", for the admission of air to the inside
of the lamp.
The top plate f, is formed from a piece of sheet metal having a central opening fl
with the ends turned inwards at ff, to form hooked edges or grooves adapted
to respectively receive the right angled flanges c, d, formed along the top edges
of the opposite side frames c, d, and which said sides and bottom are secured
together by closing the grooves of the one part upon the flanges of the other.
The breaker g, see Figures 11 and 12 is made from a sheet metal blank bent
into a curved figure, and is secured to the top plate, above the central opening
by ears g, upon it taking through piercings f, in the said plate and being
clenched upon the underside.
The extreme top or roof h, of the lamp, represented separately in Figures 9
and 10, is formed from a sheet of metal bent into an arched figure, with the
terminations thereof, at front and back, provided with longitudinal channels 1, 2,
adapted to receive and be closed onto the front and back edges f, f, of the
top plate, whilst the metal is extended downwards below the said chanuels into
flanges, which respectively form the top portions of the front and back
of the lamp.
The side glazings j, are set in separate bezels, and are soldered in place to
the side frames c and d, and the front glazing , is set in a bezel, which is
soldered to the top front extension of the roof, the extension a', of the
bottom #,
and the right angle edges, d³, of the opposite side frames c, d, which
said parts are thereby secured to one another and together form the front, whilst
the rear extension of the said lamp is soldered or otherwise connected to the
top rear edge parts of the side frames, and its lower edge forms the abutment for
the top of the hinged door.
The before described invention is applicable also to four sided lamps in which
the sides are set at an inclination so as to form a lantern or lamp with taper
sides, and we also wish it to be understood that instead of the flanges being on
the frame side elements, they may be carried on the top and bottom plates and
the channels or grooves which are to receive and be closed upon the same may be
formed upon the side frames. Our invention is also applicable to various other

page_text: forms or styles of four-sided lanterns or lamps in addition to the particular form
of cart hand lamp herein described.
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 Making up the body part of a four-sided lantern or lamp from two side
parts, and top and bottom parts, the latter having extensions adapted to form the top
and bottom portions of the front and back, substantially as described and set forth.
Secondly-In a four-sided lamp made up of top and bottom parts with two
sides as referred to in the preceeding claim, connecting together or assembling
the said parts without soldering, by engaging flanges upon the side portions into
channels or grooves formed by turning over the edges of the top and bottom parts,
and then closing the said engaged parts together, substantially as herein described
and set forth.
Thirdly In a four-sided lamp as referred to in the First Claim, a bottom
having a flange or upward extension adapted to form a part of the front and having
turned over edges at the sides adapted to be engaged by flanges at the bottom
edges of the opposite side parts, substantially as described and set forth.
:
Fourthly In a four sided lamp, as referred to in the First Claim, the employ-
ment of a cowl or roof part, consisting of a curved piece of metal, with grooves or
channels along the back and front to receive the plain edges of the top breaker
plate, and with flange extensions below the said channels which respectively form
the top portions of the back and front of the structure, substantially as described
and set forth.
Fifthly A four sided lamp, comprising a bottom plate, two sides frames or
parts, a top breaker plate and a roof or cowl, formed in such a manner as to admit
of the several parts being assembled mainly without soldering, substantially as
described and set forth.
