Improved Means for Fixing or Fitting Incandescent Electric Lamps
into Lanterns.
We, JAMES MOORES and HENRY OLIVER FARRELL, both of 15, Hanging Ditch,
Manchester, in the County of Lancaster, do hereby declare the nature of this
invention to be as follows;
-
These improvements relate principally to the fixing or fitting of small incan-
descent electric lamps into lanterns suitable for cycles or other vehicles or for
other portable lamps.
For this purpose we form the rear end of the lantern (which in the case of a
cycle lamp may consist merely of a casing for a reflector and a lens in front thereof)
with a hole through the centre, behind which is a short socket screwed upon the
inside, the hole being less in diameter than the interior of the socket so as to
leave a shoulder or internal flange all round the same. Or the socket may be
provided with any other form of abutment at its inner end.
The lamp cap is also made with a similar flange or other equivalent projecting
device and the lamp is passed into the rear end of the lantern or reflector until
the flange or projection of the cap comes against the shoulder or abutment before
mentioned.
It is then secured in this position by means of a suitable follower which is screwed
into the socket.
The follower may be fastened into the socket by other means than by a screw.
We also propose to provide the follower with the terminals of the leads so
arranged that when it is in position the said terminals are brought into contact
with the terminals of the incandescent lamp.

Improved Means for Fixing or Fitting Incandescent Electric Lamps
into Lanterns.
We, JAMES MOORES and HENRY OLIVER FARRELL, formerly of 15, Hanging
Ditch, now of 26, Victoria Street, Manchester, in the County of Lancaster,
Electrical Engineers, 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;--
These improvements relate principally to the fixing or fitting of small incan-

page_text: descent electric lamps into lanterns suitable for cycles or other vehicles or for
other portable lamps.
The manner in which our said invention is to be performed or carried into
practical effect will be readily understood on reference to the sheet of drawings
hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a section of our invention complete with lens and
reflector. Fig. 2 is a section of the follower detached, and Fig. 3 a similar view
of the lamp and reflector detached.
For the purposes of our invention we form the rear end of the lantern which (in
the case of a cycle lamp as illustrated on Fig. 1) may consist merely of a casing a
for a reflector 6 (and à lens c in front thereof) with a hole through the centre,
behind which is a short socket d screwed upon the inside, the hole through the
reflector b being less in diameter than the interior of the socket d so as to leave a
shoulder or internal flange e all round the same. Or the socket & may be pro-
vided with any other form of abutment at its inner end.
The lamp cap f (see also Fig. 3) is also made with a similar flange g or other
equivalent projecting device, and the lamp h is passed into the rear end of the
lantern or reflector 6 until the flange or projection g of the cap f comes against the
shoulder or abutment e before mentioned.
It is then secured in this position by means of a suitable follower i shewn detached
at Fig. 2, which is screwed into the socket d.
The follower may be fastened into the socket by other means than by a screw.
We also propose to provide the follower with the terminals kk' of the "leads"
so arranged that when it is in position the said terminals are brought into contact
with the terminals of the incandescent lamp, as seen by the drawing.
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:-
The improved means for fixing or fitting incandescent electric lamps into lanterns
substantially as hereinbefore described and illustrated by the drawings hereunto
annexed
