Improvements in or connected with Jet Apparatus for Lime and
other Lights.
I, ABRAHAM KERSHAW, of Cankerwell Lane, Leeds, in the County of York,
Scientific Instrument Maker, do hereby declare the nature of this invention to be
as follows:-
:='
Various means have hitherto been employed for the purpose of adjusting the position
of jet burners used in connection with lime and other lights, but such arrangements
have either been inefficient in their adjustment, or the expense of construction has
been too great to allow of their general use. Now the object of my invention is
to construct jet burners in such a manner that they may be efficiently adjusted,
whilst at the same time the cost of manufacture is considerably reduced.
According to my invention I mount a bracket between two parallel gas tubes, to
which bracket I attach a flat spring or plate, projecting vertically or nearly so
above the said bracket. To the upper part of this plate I attach a bracket carrying
a tube which hangs parallel or nearly so to the said plate. Within this tube I
provide a second tube, having a collar at its upper end, and being free to turn
within the first tube. The collar at the upper end of the second tube is provided
with a lug for receiving an adjusting screw, which latter has its bearing in the
bracket carrying the first tube.
In the aforesaid collar is fitted a clamping screw for the purpose of fixing the
second tube to a pillar attached to the bed plate. An adjusting screw passes
through the bracket at the base of the plate and bears against the first tube.
Should it be required to move the burner to the right or left, the adjusting
screw, connecting the bracket at the upper part of the first tube with the lug on
the collar of the second tube, is turned, thus turning the whole burner arrangement
to the right or left with the fixed pillar as a centre. If the position of the burner
is required to be raised or lowered, the adjusting screw passing through the bracket
at the base of the plate is turned either out or in. This movement of the screw
alters the distance between the bracket and the lower part of the first tube, at the
same time bending the spring plate. Should the spring plate be undesirable, a
hinged plate could be employed.

COMPLETE SPECIFICATION.
Improvements in or connected with Jet Apparatus for Lime and
other Lights.
I, ABRAHAM KERSHAW, of Cankerwell Lane, Leeds, in the County of York,
Scientific Instrument Maker, 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 :—
Various means have hitherto been employed for the purpose of adjusting the
position of jet burners used in connection with lime and other lights, but such
arrangements have either been inefficient in their adjustment, or the expense of
construction has been too great to allow of their general use. Now the object of
my invention is to construct jet burners in such a manner that they may be
TO11

page_text: efficiently adjusted, whilst at the same time the cost of manufacture is considerably
reduced.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer to
like parts in all the figures.
$
Fig. 1 is a side elevation, Fig. 2 is a plan, and Fig. 3 is a part end elevation, of
a burner constructed according to my invention. Figs. 4, 5, 6, and 7 are detail
views.
According to my invention, I mount a bracket A between two parallel gas
tubes B B, and to the upper part of the bracket A I hinge a bracket C, which is
joined with or forms part of a tube D. A spring E is fastened to the bracket A,
thus tending to turn the bracket C upon its hinge C in a forward direction.
Within the tube DI provide a tube F, having a collar G at its upper end, and
being free to turn within the tube D. The collar G is provided with a lug G¹ for
receiving an adjusting screw H, which latter has its bearing in a lug C₁ situated on
the bracket C. The adjusting screw H may work directly in the lug G', or it may
work in a separate piece G as shewn at Figs. 1 and 2, and only be employed for
drawing the lug G₁ backwards, a spring being employed to press the lug G¹
forward on being let out by the screw H.
A clamping screw K is fitted in the collar G for the purpose of fixing the tube F
to the fixed pillar L which is attached. to the bed plate of the lantern in the
ordinary way.
When the tubes F and D are placed together, a punch is forced in
at the lower part of the tube F, which opens out the tubes as shewn at Fig. 7, thus
preventing the tube D from slipping off the tube F, whilst at the same time. it is
free to turn thereon. An adjustable screw M passes through the lower part of the
bracket A and bears against the lower end of the tube D.
I construct the forward part of the burner in the ordinary way, and as my
invention only refers to adjusting its position up or down, or to the right or left,
there is no need to describe the said forward part.
The working of apparatus constructed according to my invention is as follows:
Should it be required to adjust the burner to the right or left, the adjusting
screw His turned, thereby turning the whole of the burner arrangement to the
right or left, with the fixed pillar L as a centre. When it is required to raise or
lower the position of the burner, the adjusting screw M is turned, thereby rocking
the whole burner arrangement upon the hinge C, whilst the screw M and spring E
.working against each other form a most perfect adjustment without any back-lash.
In the case of the employment of a spring bracket in place of the hinge C², the
spring itself would act as the hinge, and the screw would bend it as required.
It will be obvious to anyone having a knowledge of mechanical work, that the
adjustments between the tubes F and D may be obtained in many ways; as, for
instance, by having a worm pivotted on one tube and gearing with a tooth wheel on
the other tube; or by having a tooth wheel on one tube gearing with a toothed
wheel or its equivalent on the other tube. The employment of one tube turning
around an inner tube could also be modified by employing a frame turning around a
tube with a like effect, but many such modifications can be made without departing
from my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim as my improvements in or connected with jet apparatus for lime and other
lights is as follows:-
1. The two tubes, one within the other, the inner tube for clamping a fixed
pillar, and the outer tube adjustably connected to the inner tube, substantially as
and for the purposes set forth.
2. The combination of the tube F, collar G, lug G¹, adjusting screw H, lug C¹,
bracket and tube D, substantially as and for the purposes herein set forth.
3. The combination of the tube D, bracket C, hinge C2, and bracket A, adjusted

page_text: by the screw M and spring E or their equivalents, substantially as and for the
purposes set forth.
4. The combination of the bracket A, gas tubes B B¹, bracket C, lug C¹, tube D,
spring E, tube F, collar G, lug G', piece G2, screw H, spring J, screw K, pillar L,.
and screw M, substantially as and for the purposes set forth.
5. The arrangement, construction, and combination of the various parts forming
my improvements in or connected with jet apparatus for lime and other lights,
substantially as and for purposes herein set forth, together with any mere-
modification or modifications thereof.
