Improvements in Oxy-hydrogen or Lime-light Jets.
ALFRED SUITER, 2 Como Road, Forest Hill, Kent, Mechanical Engineer, do hereby
declare the nature of this invention for IMPROVEMENTS IN OXY-HYDROGEN, OR LIME
LIGHT JETS to be as follows:-
Lime Lights as ordinarily constructed require a separate jet-or at any rate
separate nozzles or burners-for each kind of light, such as "blow-through,”
"mixed" and "ethoxo;" although different nozzles or burners are sometimes used
on the same jet, they constitute loose parts, and are apt to be lost or mislaid.
In the lime adjusting portion of the apparatus the revolving motion is much too
fast, and when the central screw is of sufficiently sharp pitch, it runs itself down by
the least touch or joggle; and when a worm wheel working on a central screw, and
worm are used, although it gives the proper speeds, it, at the same time is complicated
and costly.
The object of this invention is to combine the different kinds of jets in one, so that
the same jet can be used for either a "blow through," "mixed," or "ethoxo" light or
others, and that there shall be no loose parts. Also to give a proper adjustment of
the lime by a more simple and effective mechanism than has been employed
heretofore.
In carrying out my invention, I introduce between the nozzle, or burner, of the jet,
a four way valve, piston, screw down or other valve, communicating on the one side
with the separate gases, and on the other with the openings in the nozzle, or burner;
the passages in the four way or other valve, are so arranged, that, when the four way
or other valve stands in one position, there are clear ways through for the separate
gases to pass to their respective openings in the nozzle, or burner, thus forming a
blow through” light, and upon a movement of the four way, or other valve, one gas
is diverted from one opening in the nozzle, or burner, into the other passage containing
the other gas, thus forming "mixed" and "ethoxo "lights.
To regulate the size of the opening in the nozzle, or burner, as required by different
lights, the four way or other valve can be formed in the burner itself, and so arranged
that the action of adjusting it, for either kind of light, has the effect-by suitable
screw or other motion-of withdrawing from or introducing into the opening in the
nozzle, or burner, a tube or liner, or loosely fitting plug, so, either enlarging or
diminishing the area of the opening.
For adjusting the lime I mount the pillar for supporting the lime upon a suitable
bracket or central pin, the pillar being free to turn on its axis, and move vertically;
upon this pillar is cut a spiral groove, provided with teeth or cogs, into these a worm
engages, which is fitted on the spindle that extends to the back end of jet. Upon
turning the worm, the lime pillar receives a rotary and a vertical motion at the same
time, owing to the worm being capable of a rotary motion only; the amount of rise
and fall of lime pillar-per revolution-being dependent upon the pitch of the
aforesaid toothed spiral groove.

COMPLETE SPECIFICATION.
Improvements in Oxy-hydrogen or Lime-light Jets.
I, ALFRED SUITER of 2, Como Road Forest Hill in the County of Kent
Mechanical Engineer, 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 :-
Lime lights as ordinarily constructed require a separate jet-or at any rate
separate nozzles, or burners, for each kind of light, such as "blow-through,"
"mixed" and "ethoxo;" although different nozzles or burners are sometimes used
on the same jet, they constitute loose parts, and are apt to be lost or mislaid.
In the lime adjusting portion of the apparatus the revolving motion is much too
fast, and when the central screw is of sufficiently sharp pitch, it runs itself down by
the least touch or joggle; and when a worm wheel working on a central screw and
worm are used, although it gives the proper speeds, it at the same time is complicated
and costly.
The object of this invention is, to combine the different kinds of jets in one, so that
the same jet can be used for either a "blow-through," "mixed," or "ethoxo" light or
others; and that there shall be no loose parts. Also to give a proper adjustment of
the lime by a more simple and effective mechanism than has been employed
heretofore.
In carrying out my invention, I introduce between the nozzle or burner of the jet,
and regulating taps, a four-way valve, piston, screw-down, or other valve, com-
municating on the one side with the separate gases, and on the other with the
openings in the nozzle or burner; the passages in the four-way or other valve are so
arranged that when the four-way or other valve stands in one position, there are clear
ways through for the separate gases to pass to their respective openings in the nozzle
or burner, thus forming a "blow-through" light; and upon a movement of the
four-way or other valve, one gas is diverted from one opening in the nozzle or burner,
into the other passage containing the other gas, thus forming "mixed" and "ethoxo"
lights.
To regulate the size of the opening in the nozzle or burner, as required by different
lights, the four-way or other valve can be formed in the burner itself, and so
arranged, that the act of adjusting it for either kind of light, has the effect by suitable
screw or other motion-of withdrawing from, or introducing into the opening in the
nozzle or burner, a tube or liner, or loosely fitting plug, so either enlarging or
diminishing the area of the opening.
For adjusting the lime, I mount the pillar for supporting the lime, upon a suitable
bracket or central pin, the pillar being free to turn on its axis, and move vertically;
upon this pillar is cut a spiral groove provided with teeth or cogs, into these a worm
engages, which is fixed on the spindle that extends to the back end of jet. Upon
turning the worm, the lime pillar receives a rotary and a vertical motion at the same
time, owing to the worm being capable of a rotary motion only; the amount of rise
and fall of lime pillar-per revolution-being dependent upon the pitch of the
aforesaid toothed spiral groove.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing, in which Figure 1 is an elevation
and Figures 2 & 3 are elevations (with lime adjusting portion omitted) taken at
right angles to Figure 1, of the portion of a lime light jet constructed according to
my invention. Similar letters in all the figures represent similar parts.
To describe the first portion of my invention, A and B, are tubes conveying gases
to nozzle of jet. a, is the plug of four-way valve by which the different lights either
"blow-through" or 66 mixed are produced, or for shutting off the light. Figure 2
represents the four-way valve in position for the "blow-through" light, and Figure 3,
for the "mixed" light; b is hydrogen port, and c, oxygen port. When the four-way
valve is in position for "blow-through," as in Figure 2, the hydrogen gas enters from

page_text: the supply tube A, by the port b, along the passage d, to the outside nozzle e; the
oxygen enters from the supply tube B, by the port c, along the centre passage f, to
centre nozzle g; Figure 3 represents the four-way valve when it has been given half
a revolution to produce the "mixed" light, when the hydrogen follows the passage h,
to centre passage, f, to centre nozzle g; the oxygen entering by passage i, going in
the same direction, both gases mixing; by turning the plug a, of four-way valve a
certain distance only, the light can be turned out, forming a dissolver, the regulating
screw j, forming a by-pass, prevents the light being turned right out.
It will be obvious, that, if the dissolving arrangement is not required, instead of
using a four-way valve, a valve can be used that simply diverts the hydrogen gas from
one passage to the other, allowing the oxygen to follow the same course for both
kinds of light. The outer nozzle e, is made telescopic, so as to push out of the way
when the "mixed" light is being used. The outer nozzle instead of being telescopic,
could be fixed at the side of the oxygen nozzle, on the plug of the four-way valve,
so that the act of turning the plug throws the nozzle out of the way, and changes
the direction of the gas at the same time.
To describe the second portion of my invention; k, is lime pillar working in
standard c, l, is toothed spiral groove into which the worm m, works, connected to
milled head n, by spindle o; instead of spindle o, and milled head n, only working
the lime, I continue the spindle o, and engage it into the plug of four-way valve a,
by cross pin p, and notch p', so that the same spindle and milled head can be used
for adjusting the lime, and for dissolving. To work the lime the spindle o, is pulled
back till pin p, is clear of notch p', when the spindle is then free to turn on
its axis.
Having now particularly described, and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
כי
"
1. In oxy-hydrogen or lime light jets; the use of a four-way or other valve
for changing the light to either " blow-through or mixed," substantially as
herein before described.
2. The use of a spiral worm wheel for adjusting the lime, substantially as herein-
before described.
3. The combination of parts forming the improved oxy-hydrogen or lime light
jet, substantially as hereinbefore described and represented in the accompanying
drawing.
