Improvements relating to Cycle and like Lamps, and to the
Manufacture of such Lamps.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, of H. Miller and
Company, Limited, Miller Street, in the City of Birmingham, Lamp Manufac-
turers, do hereby declare the nature of this invention to be as follows;-
This invention relates to certain improvements in-cycle and like lamps, and to
the manufacture of such lamps, and has for its object, to dispense with the use of
solder in the making up of the said lamps.
The improvements consists, first, in making one of the sleeves of the spring
back and the joint of the opening part of the lamp in one piece; secondly, in the
making of the bracket part of the joint of the movable front; thirdly, making
the spring for closing the front and its back or cover all in one piece; fourthly,
in an improved method of fixing, and fifthly, in affixing the side light frames in
their sockets without soldering.
?.
In carrying out our invention, the shell dy part of the lamp may be of a
spherical shape and diagonally divided in portions, the one surmounting a
base and being fixed and the other and movable front part being hinged and up-
wardly swinging from the top of the fixed part, which is supported by a spring
back carrying an attachment socket, which takes upon an ordinary lamp bracket.
The top sleeve of the said spring back and a part of the knuckle joint is made
from a single blank of sheet metal, the sleeve part of which is attached to the
top of the fixed body of the lamp by rivetting, clinching, soldering or otherwise.
The hinged bracket part of the said joint surmounts the hinged section of the
lamp and between it and the crown and breaker, and consists of an interposed ring
of metal with the back or after part formed into a knuckle joint, made in one piece
and pinned to the joint carried by the sleeve as aforesaid. The said bracket is
affixed in its assigned position by a shouldered neck of the crown passing through
the said ring and through a hole in the top of the body section and then being
clenched or spun around the edges of the said hole.
The spring for fixing the front reflector and the glazed bezel or bell, is made in
one piece of metal with its box by taking a blank, somewhat of the figure of a
letter T, forming the rear part into the top and sides of the box and turning the
spring part backwards upon the underside of the box, whilst the fore part is
cranked, thus making the spring and box, which may be attached in any suitable
way to the cone, all in one piece.
The bell is fixed within the front opening of the body, or the movable part of
the same, by forming it with a shouldered and contracted neck, which is passed
inwardly through the said opening, and then has a conical supplementary bearing
ring introduced over it. The whole is then affixed by the turning of the extreme
inward edge of the bell back and over the edge of the introduced ring, thereby
dispensing with soldering.

page_text: The side light fitting consists of a stepped or socketted ring or frame of two
diameters, the smaller one passing through an opening in the side of the shell
body and then the edge is clenched or turned over from the inside. The other
fitting consists of a loose ring or frame carrying the glazing and having a flange
at its edge with the periphery of the same diameter as the inside socket of the
fixed frame, which forms the bed for the glazing. Then by turning over the lip
of the bed upon the outer edge of the glazing frame, the whole is secured in posi-
tion without soldering.

Improvements relating to Cycle and like Lamps, and to the
Manufacture of such Lamps..
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, of H. Miller and
Company, Limited, Miller Street, in the City of Birmingham, Lamp Manufac-
turers, 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 certain improvements in cycle and like lamps, and to
the manufacture of such lamps, and has for its object, to dispense with the use of
solder in the making up of the said lamps.
The improvements consist, first, in making one of the sleeves of the spring back
and the joint of the opening part of the lamp in one piece; secondly, in the mak-
ing of the bracket part of the joint of the movable front from sheet metal; thirdly,
in making the spring for closing the front and its back (or cover) all in one piece;
fourthly, in an improved method of fixing the bell in without soldering, and
fifthly, in affixing the side light frames in their sockets without soldering.
Figure 1 of the accompanying drawings represents a side elevation of one form
of bicycle lamp embodying our improvements.
Figure 2 is a back elevation of the same, and
Figure 3 is another view, showing the body of the lamp and portions of the arms
of the compensating spring back, in section.
The said lamp, as represented, consists essentially of a spherical shaped body
part a, divided diagonally into two portions a¹, a³, the former of which surmounts,
and is made a fixture to, the base or oil tank b, whilst the other and movable front
part 2, is hinged at a³, to, and swings from, the top of the fixed part, to which
the arms c, of the compensating spring back c, are jointed, the said spring back
being provided with the usual attachment socket c, for taking upon the lamp
bracket of a machine. The swinging front section carries the cowl a at its
crown, the glazed cone d at its front, whilst the sides are fitted with the side-
lights e.
The top sleeve 3, wherethrough the joint pin c, of the top arms of the spring
back passes, has integrally formed with it, two (or more) of the knuckles, of the
hinge a³, said sleeve and knuckles being made from a blank of sheet metal, shown
separately in plan and edge view in Figure 4 and marked c, whilst Figure 5

page_text: represents the said fitting in underside plan and end view, with Figure 6 repre-
senting, upon an enlarged scale, a section of Figure 5 upon the dotted line .
From these views it will be seen that the knuckles are fashioned out of the
straps, and that the ends of the blank are of less breadth than the body part,
which said ends are brought together to form ears 8, adapted to be passed from
the outside of the lamp through holes a³, in the back and be there clenched upon
the inside, thus affixing the combined sleeve and joint knuckle to the lamp,
although, if necessary, the combined knuckle and sleeve may be attached by rivet-
ting or soldering.
The other knuckle a, (or knuckles) of this hinge, is carried by a bracket a²,
surmounting the hinged section a², of the lamp and coming between the crown
thereof and the cowl. This bracket is made from a sheet metal blank, repre-
sented separately in plan and edge view in Figure 7, which is fashioned into the
form shown in Figure 8, consisting of a ring part a³, carrying at its back or after
part, the knuckle a6, which is jointed to the knuckles c, on the fixed half of the
lamp by means of a joint pin a¹0. This ring surrounds the hole in the top or
crown of the hinged body section, and is secured in its assigned position by a
shouldered neck a", of the cowl being passed through the said ring and crown
piercing and then being clenched or closed over the edges of the said piercing, as
represented in the sectional view Figure 3.
The fitting which it is proposed to employ for the attachment of the side lights,
is made up of two parts e¹, e. The former is represented in edge view, cross sec-
tion and elevation in Figure 9, and consists of a loose tray or frame, cut out from
sheet metal and having an opening e³, in its front through which a part of the
glazing e, may project. A flange e, is made around the bottom edge of this tray,
with its periphery of a diameter suitable for taking and fitting within the other
parte, of the fitting, which consists of a stepped ring or frame of two dia-
meters e, e', the larger diameter e, receiving the flange e, of the part e¹, with
the step e, constituting the bed forming the ring. In making up and attaching
the fitting, the glazing is first placed within the inside of the tray e¹, and then
this latter is placed within the ring e, as shown in the sectional view Figure 11.
The two parts are next secured together by closing the edge e, of the one over
the flange e, of the other, after which the part of smaller diameter e', is' placed
through a hole all, in the side of the hinged body portion of the lamp and clenched
on the inner side thereof, as represented in Figure 12, thus completing the attach-
ment of the side-light fitting.
Figure 13 represents a side elevation of the glazed cone or bell of the lamp and
Figure 14 is a section thereof, shewing the method of attaching the said cone to
the body, whilst Figure 15 represents a like view as Figure 14, but on an enlarged
scale. In Figures 14 and 15 the spring fastening of the glazed bezel of the cone
is also shown in section.
Figure 16 represents the cone and portion of the body of the lamp separated.
Figure 17 represents a section, edge view and front elevation of the conical bear-
ing ring by means of which the connection is effected.
In making this connection, the contracted inner end or neck , of the cone <,
is passed through the front opening a2, in the hinged body section and then has
the conical ring d2, introduced over it, after which the body, cone and ring are
secured together, without soldering, by turning back the extreme inward edge d³,
of the said cone over the adjacent end d, of the said ring, whose outer end d³, is.
of greater diameter than the opening a¹².
Figure 18 is an elevation of the spring catch for fastening the glazed bezel to
the cone, which spring is made in a piece with its box or casing.
Figure 19 is a section of the said combined spring and box and
Figure 20 is a topside plan of the same.
Figure 21 represents, upon a reduced scale, the blank from which the said com-
bined spring and box is made.

page_text: This blank f, has an enlargement or head f¹ at the end f, and which is fash-
ioned so as to form the top. f3, and sides f, of the box part f5, (see Figures 18, 19
and 20). The other or tongue part fo, of the blank is doubled upon itself to form
the spring f, which comes upon the underside of the box, whilst the middle part f8,
of the tongue is fashioned into the catch fo, behind the shoulder f¹0, of which
the bezel of the lamp snaps. The sides of the box are soldered or otherwise
attached to the walls of the cone, and the fastening may be employed for securing
the front reflector ring in addition to the glazed bezel in lamps in which they are
employed.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
First In cycle lamps, making the top sleeve 3, of the spring compensating
back from sheet metal and in one piece with a knuckle or knuckles, of the
joint or hinge between the body sections of the lamp, substantially as described
and set forth.
Secondly-In cycle lamps, making the knuckle (or knuckles) a, the bracket a",
and the attachment ring a³, from sheet metal and in one piece, substantially as
described and set forth.
Thirdly-In cycle lamps, attaching the joint-knuckle (or knuckles) a6 and
bracket a', without soldering, to the lamp by means of a ring such as a³, preferably
coming between the top of the lamp and the neck of the cowl, and being secured
by closing over the edges of the said neck, substantially as described and set forth.
Fourthly-In cycle lamps, securing the side-lights to their framings and the
framings to the lamp, without soldering, by means of a loose tray or frame such
as e¹, and a carrier and attachment ring e, with the two parts secured together
and to the lamp, in the way substantially as described and set forth.
Fifthly:-In cycle lamps, connecting the glazed front cone or bell to the body
of the lamp, by the employment of a bearing ring surrounding the inserted or
necked end of the bell and secured by spinning or turning the inward edges of
the neck over the contiguous edges of the said ring, substantially as described and
set forth.
Sixthly-In cycle lamps, making the spring, catch and box of the front fas-
tening of the lamp from a single blank of sheet metal, substantially as described
and set forth.
