PROVISIONAL SPECIFICATION.
Improvements in Burners and Collars of Lamps.
I, JOHN WILLIAM COCKERILL of 5 George Street, Hanover Square London, W.,.
Physician and Surgeon, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the burners and collars of lamps, and consists in fixing a
spring to the burner, so adjusted that when the latter is attached to the collar of the
lamp in the ordinary way, that is, by means of a clip upon the burner passing over a
bolt upon the collar then the spring falls behind a catch on the collar bolt thus
locking the burner to the collar. They can then only be separated by first raising
the spring over the catch upon the collar bolt.
Dated this Sixteenth day of July 1896.

COMPLETE SPECIFICATION.
Improvements in Burners and Collars of Lamps.
I, JOHN WILLIAM COCKERILL, 17 Whitehali Place, London S.W. late of
5 George Street, Hanover Square, London W. Physician and Surgeon, 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 :-
My invention relates to burners and collars of lamps and consists in fixing a spring
to the burner, so adjusted that when the latter is attached to the collar of the lamp
in the ordinary way, that is, by means of a clip upon the burner passing over a bolt
upon the collar. Then the spring falls behind a catch on the collar bolt, thus locking
the burner to the collar, so that they can only be separated by first raising the raising
spring over the catch upon the collar bolt.
In order to more clearly describe this my invention I have appended hereunto an
illustrative sheet of drawings upon which are figures and numbers of reference.
Fig. 1, is a view in elevation showing the lower part of a lamp burner upon which
the clip and spring is situated.
Fig. 2, is a view of the collar upon the oil container, showing the bolt, over which
the spring is made to fall.
Fig. 3, is a view showing the burner attached to the collar and locked by the
spring according to this my invention.
Fig. 4, is a detailed plan view of the spring.
6, is the burner, the lower part of which only is shown. 7, is the usual clip for
attachment to the reservoir mount or collar 8, by passing along the underside surface
of the projection 9. Two of these clips 7 and projections 9 are generally used and
placed diametrically to each other. 10 is a bolt or catch which is conveniently made
as shown by turning up the end of the projection 9. 11, is a flat spring which is
secured to the burner at 12. This spring is so arranged that as the burner is being

page_text: turned round-in order to pass the clips 7 underneath the projections 9-it rides
upon the bolt 10 until it has passed it and then falls behind it as seen in Fig. 3, and
thus prevents a return movement of the clips 7, so that the burner is locked in
position.
To separate the burner from the collar it is only necessary to first raise the spring
by means of its projecting part 13, when the burner may be turned back as usual
and removed.
It will be readily seen that the bolt 10 may be provided upon the collar if desired
quite independent of the projection 9, and may be applied to or combined with
fastenings other than the clips 7 and projections 9.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In burners and collars of lamps the combination with the burner and with the
reservoir mount or collar, of a spring 11 upon the one part acting in conjunction
with a bolt 10 upon the other part, substantially as set forth and shown.
2. The general combination and arrangement of parts constituting these my
improvements in lamp burner fastenings as set forth and shown upon the drawings.
Dated this 23rd day of December 1896.
