Improvements in Oil Spraying or Atomizing Devices for Gas
Apparatus.
I, CHARLES RUSSELL COLLINS, a citizen of the United States, residing at
No. 727, Brown Street, in the City of Philadelphia, in the County of Philadelphia,
and State of Pennsylvania, Gas 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:-
My invention relates in general to apparatus for the production of carbureted
water-gas; and it relates more particularly to certain improvements in the device
for injecting oil or other liquid hydrocarbons into the water-gas.
The principal objects of my present invention are first to obviate waste of the
liquid hydrocarbon and to hasten, facilitate and finally attain a more perfect
carburation of the water-gas than has hitherto been possible; second, to provide a
simple, durable, efficient and comparatively inexpensive device for economically
injecting liquid hydrocarbons into a supply of water-gas in such manner that the
same is thoroughly and completely carbureted; third to so construct and arrange
the various parts of the device as that the same may be readily detached and
cleaned or repaired and subsequently assembled for use; and fourth to provide
means for adjusting the operative parts of the device in order to compensate for
expansion, contraction and wear of the parts thereof.
My invention stated in general terms consists of an oil spraying and atomizing
device for gas apparatus, comprising a sectional casing, a diaphragm provided with
inclined apertures for imparting rotary motion to the jets or streams of liquid
hydrocarbon as they are discharged from the casing, and means for adjustably
seating said diaphragm and-
My invention further consists of the improvements hereinafter described and
claimed.
The nature, objects and scope of my invention will be more fully understood
from the following description taken in connection with the accompanying drawings
forming part hereof; and in which
Figure 1, is a view partly in side elevation and partly in central section of an oil
spraying or atomizing device embodying features of my invention in application to
the wall of a chamber in a gas apparatus.
Fig. 2, is a top or plan view drawn to an enlarged scale of the diaphragm
illustrated in Fig. 1, showing inclined apertures therein for imparting rotary motion
to the escaping jets or streams of liquid hydrocarbons and
Fig. 3, is a section taken on the line 3-3 of Fig. 2.
Referring to the drawings, the main casing of the oil spraying or atomizing
device comprises a tube a, externally threaded at the respective extremities thereof,
a nipple b, mounted upon one extremity of the tube a, a nozzle c, inserted into the
nipple b, an internally threaded thimble d, mounted upon the other extremity of
the tube a, and provided with a T-union d', and with a detachable stuffing-box d³.
is a spindle provided with an exterior thread e', engaging a thread cut or other-
wise formed upon the internal wall of the stuffing box d and with a hand wheel e*,
accessible from the outside of the main casing, in order that the spindle e, may be
shifted backward and forward or upward or downward in the main casing of the
device by the simple operation of turning the hand wheel in one direction or
the other as required. f is a diaphragm detachably connected with the spindle e
by means of a screw f1, and adapted to be firmly seated upon the internal edge c¹,
of the nozzle c, that is, for this purpose permitted to extend through the nipple b,
as shown in Fig. 1. f, are inclined apertures drilled or otherwise formed in the
diaphragm. The number and relative dispositions of these apertures f³, may be

page_text: varied and the inclination thereof may be increased or diminished, the object being
to cause a rotary motion to be imparted to the jets or streams of liquid hydro-
carbon as they are discharged through the nozzle. g is a bushing mounted upon
the exterior of the casing of the device and adapted to afford means whereby the
same may be conveniently secured to place.
In use the T-union d', is connected with a pipe d³, communicating with a suitable
supply of hydrocarbon, not shown, and the bushing g, is screwed or otherwise
inserted into a suitable aperture h, formed in one of the walls i, of a chamber to
which water-gas is supplied and in which it is carbureted, and a covering of asbestos
or analogous substance or material j, is preferably applied to the external portions of
the casing subjected to the heat of the gas.
The mode of operation of the hereinabove described oil spraying or atomizing
device is as follows:-
Oli or other liquid hydrocarbon under pressure enters the main casing through
the T-union d', and after passing through the perforated diaphragm fescapes through
the nozzle c, into the carbureting or other chamber. In its passage through the
perforations 3, of the diaphragm f, the supply of oil is broken up into jets or
streams and the inclination of the perforations * causes a rotary motion to be
imparted to the jets or streams as they issue from the nozzle c.
This rotary or spiral motion of the issuing jets or streams is important, because it
ensures the thorough carburation of the gas and prevents the deposition of liquid
hydrocarbon upon the walls of the carbureting or other chamber. By these means
the quality of the carbureted gas is improved, and a material economy in liquid
bydrocarbon is effected.
The exterior casing is exposed to a considerable degree of heat and consequently
expands and contracts. However, the diaphragm f, may be constantly maintained
firmly to place in contact with its seat c', by means of the hand wheel and
spindle e, so that leakage of the liquid hydrocarbon around the diaphragm f, is
completely obviated. Inasmuch as the respective parts of the spraying and
atomizing device are all detachable it follows that they may readily be removed
and repaired or cleaned, and that the diaphragm f, may be detached and replaced
by another diaphragm having a greater or less number of apertures disposed at a
greater or less inclination, as may be required.
Having now particularly described and ascertained the nature and objects of my
said invention and in what manner the same is to be performed, I declare that
what I claim is
1. A spraying and atomizing device for gas apparatus, comprising a casing, a
diaphragm or plate provided with transversely ranging and inclined apertures for
imparting a rotary motion to jets or streams issuing from the device, and a spindle
for adjusting said diaphragm in respect to its seat, substantially as and for the
purposes set forth.
2. An oil spraying and atomizing device for gas apparatus comprising a sectional
casing, a diaphragm or plate provided with parallel inclined apertures ranging
transversely of the plate or diaphragm for imparting rotary motion to the jets or
streams of liquid hydrocarbon and an adjustable spindle detachably connected with
said diaphragm, substantially as and for the purposes set forth.
3. In a spraying and atomizing device for gas apparatus, a diaphragm or plate
provided with transversely ranging apertures inclined in the same direction in
respect to the face of the plate or diaphragm, substantially as and for the purposes
set forth.
4. An oil spraying and atomizing device for gas apparatus comprising a tube
having a nipple connected therewith, and a nozzle applied to the nipple, a thimble
mounted on the tube and provided with a stuffing-box and union, a spindle and a
diaphragm or plate provided with transversely ranging and inclined apertures for
imparting rotary motion to jets or streams issuing from the device, substantially as
and for the purposes set forth.

page_text: 5. The combination with a carbureting chamber, a casing extending into said
chamber, an oil supply and pipe connections between said oil supply and casing, of
a diaphragm or plate provided with inclined apertures ranging transversely of said
plate or diaphragm for imparting rotary motion to jets or streams of a liquid and a
spindle detachably connected with said diaphragm, substantially as and for the
purposes set forth.
6. An oil spraying and atomizing device for gas apparatus comprising a tube, a
