Improvements in Burners or Jets for the Lime Light.
We, JAMES EDWARD ANDERSON, of 9, Crawford Passage, Farringdon Road,
and ALFRED WRENCH, of 50, Grays Inn Road, both in the County of London,
Manufacturing Opticians, do hereby declare the nature of this invention to be as
follows:-
This invention relates to burners of the kind used in magic lanterns for the pro-
duction of the lime light. Such burners as hitherto usually constructed are provided
with a spindle upon which the block of lime used with the burner is adapted to be
raised and also rotated, and, in some cases, such burners are adapted to be adjusted.
bodily both vertically and laterally relatively to the socket by means of which the
burner is supported upon the supporting pillar thereby avoiding the necessity of:
moving the said socket relatively to the pillar.
The means heretofore adopted for adjusting the burner relatively to the said
socket have been defective inasmuch as the vertical adjustment of the burner caused
the spindle carrying the lime block to be moved more or less out of a vertical
position.
The object of this invention is to provide for effecting the adjustment of the
burner without affecting the perpendicularity. of the said spindle.
In carrying out the said invention we employ a socket adapted to be fixed to the
pillar in the ordinary manner and having its upper end screw-threaded and provided
with a nut. The burner proper is carried by a second socket which slides upon the
first mentioned socket and is acted upon by the said nut, a spring being placed
between the second socket and the fixed socket in such a manner that when the nut
is turned in one direction the burner will be moved downwards against the pressure:
of. the said spring and that when moved in the reverse direction the spring will
raise the burner to keep the second socket in contact with the nut.
To effect the lateral movements of the burner the rear side of a collar upon the
second socket is provided with gear-teeth with which a pinion carried in. bearings
upon the fixed socket is designed to engage, the said pinion having a knob or handle:.
for operating it.

COMPETE SPECIFICATION.
Improvements in Burners or Jets for the Lime Light.
We, JAMES EDWARD, ANDERSON, of 9, Crawford Passage, Farringdon Road,
and ALFRED WRENCH of 50, Grays, Inn. Road, both in the County, of, London,
Manufacturing Opticians, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described, and ascer-,
tained in and by the following statement :-
This invention relates to burners of the kind used in magic lanterns for the
production of the lime light.
Such burners as hitherto usually constructed are provided with a spindle upon
which the block of lime used with the burner is adapted to be raised and also'
rotated, and; in some cases, such burners are adapted to be adjusted bodily both

page_text: vertically and laterally relatively to the socket by means of which the burner is
supported upon the supporting pillar thereby avoiding the necessity of moving the
said socket relatively to the pillar for slight adjustments.
The means heretofore adopted for adjusting the burner relatively to the said
socket have been defective inasmuch as the vertical adjustment of the burner caused
the spindle carrying the lime block to be moved more or less out of a vertical
position.
:
The object of this invention is to provide for effecting the adjustment of, the
burner without affecting the perpendicularity of the said spindle.
'In carrying out the said invention we employ a socket adapted to be fixed to the
pillar in the ordinary manner and having its upper end 'screw-threaded and provided
with a nut. The burner proper is carried by a second socket or collar which slides
upon the first mentioned socket and is acted upon by the said nut, a spring being
placed between the collar and an enlarged portion of the fixed socket.
To effect the lateral movements of the burner the rear side of a flange upon the
collar is provided with gear-teeth with which a pinion carried in bearings.upon the
fixed socket is designed to engage, the said pinion having a knob.or handle for
operating it.
.
!
To enable the said invention to be fully understood.we will describe the same by
reference to the accompanying drawing, in which:-
+ I
Figure 1 is a side elevation of a burner of the kind referred to having our:
improvements applied thereto; and,
Figure 2 is a plan of the same :
Figure 3 is a section on the linear, Figure 2; and,..
Figure 4 is a section on the line yy, Figure 3.
a, a are the gas tubes of the burner which terminate in the nozzle and are
provided with the cocks c, c; and d is the spindle for carrying the blocks of lime,
the said spindle being adjustably mounted in a well known manner. upon the
tubes a, a and adapted to be operated by the rod.e.
is the socket by means of which the burner is supported upon the pillar g
secured to the usual sliding tray h, the said. socket being adjustable upon the
pillar and adapted to be fixed in any position thereon by means of the thumb-
!
screw h
→
is the socket.or.collar to which the burner tubes are secured and which slides
upon the socket f; j. is the nut which is screwed on the upper end of the socket f,
and is the spring which at one end bears against the enlarged lower portion of the
socket and at the other end against the underside of the collar i in such a manner.
as to hold the said collar in contact with the nut j. With this arrangement it will
be readily understood that by adjusting the nut j up or down upon the socket f
the burner will be correspondingly moved in a vertical direction without affecting
the vertical position of the spindle.
1, are the teeth formed upon the flange m of the collar i at the rear part thereof,
and n is the pinion which engages with the said teeth 1, 1, the said pinion having a
bearing at its lower end in a lug o formed upon the socket f and at its upper end
in a plate p screwed onto the upper end of the said socket is a milled head
attached to the spindle of the pinion n and serving for rotating the same. It will
be noticed that the pinion n is of 'considerable length and it is made in this manner
so that the said pinion will always be in engagement with the teeth / in any position
in which the burner may be adjusted vertically..
It will be obvious that when the pinion n is slightly rotated in one or the other
direction by means of the milled head-g the burner will be moved laterally by
rotating upon the socket f.
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
1. In a lime-light. buruer mounting the gas tubes upon a collar adapted to be:

page_text: adjusted vertically upon and in a direction of rotation around a supporting socket,
substantially as, and for the purposes, described.
2. In a lime-light burner the combination with the gas tubes of a collar adapted
to be adjusted vertically upon a supporting socket by means of a nut and to be
moved pivotally upon the said socket by means of a pinion engaging with teeth on
the said collar, substantially as described.
3. The manufacture and use of the improved lime-light burner hereinbefore
described and illustrated in the accompanying drawing.
