Henry Huss, Wilmington, Del., assignor, by
mesne assignments, to May Oil Burner Corpo
ration, Baltimore, Md., a corporation of Mary
land
Application March 15, 1932, Serial No. 599,022
8 Claims, (Cl. 299-420)
An object of the invention is to provide a noz
zle which will not‘corrode or erode and which
will at all times discharge a jet of ?uid in a pre
determined manner.
,
'
Another object of the invention is to provide a
nozzle having an ori?ce formed in a hard stone,
such as a diamond, a sapphire, agate or ruby,
which will not corrode or erode with heat, or
with which meshes a thread IS on a distributing
wstem I6. There is a- second casing member I‘!
which is connected with the casing member ID
by means of threads l8.
It will be seen that the distributing stem l 6 has 5
a head H] which is manufactured of a hard stone,
such as a diamond, a sapphire or agate, this hard
stone head 19 having tangential feed slots 20
which serve to feed fuel oil supplied through the
pipe I l to the casing member In and through the 10
tributor with a hard stone such as a sapphire with apertures 2| in the partition l3, the oil passing
to the bottom of the casing member I‘! adjacent
a slot or slots leading to the ori?ces.
A further object of the invention is to provide .the head 19 and thence through the tangential
under the in?uence of acids and other ?uids
10 ?owing through the nozzle, and to provide a dis
a nozzle which is particularly adapted for use
15 on fuel burners‘and which will safely and ac
curately discharge a jet of combustible fuel in a
predetermined manner under various conditions
and for a long period of time.
Additional objects of the invention will. appear
20 in the following speci?cation in which the pre
ferred form of the invention is described.
In the drawing similar reference characters
refer to similar parts in all the views, of which
Figure 1 is a sectional elevation showing a noz
zle provided with the improvement which is the
subject matter of this application.
.
Figure 2 is an inverted plan view of the nozzle
as shown in Figure 1;
Figure 3 is a plan view illustrating the nib with
30 the diamond or other hard stone having the dis
charge ori?ce; and
Figure 4 is an inverted plan view showing the
head on the distributor stem, the head being
fashioned from a sapphire or other hard stone.
In oil burners there is very often di?iculty with
the nozzle from which a jet of the fuel passes to
the ?re box because of the-corrosion and erosion
of the material adjacent an outlet ori?ce through
which a jet of fuel passes to the ?re box. It has
40 been found that when the material of which the
nozzle is constructed corrodes or erodes adjacent
the ori?ce, the fuel is not directed properly by
the nozzle and that the operation of the oil
35
' burner is, therefore, unsatisfactory inasmuch as
45 the size of the ori?ce is increased. The nozzle
which is the subject matter of this application
avoids these di?iculties, for the nozzle at the sides
of the slots which feed to the swirl chamber is
incorrodible and the nozzle at the sides of the
50 ori?ce ‘leading from the swirl chamber is also
incorrodible.
By referring to the drawing it will be seen that
a casing member I0 is connected with the supply
pipe H by threads 12, the casing member [0 hav
55 ing a partition l3 with a threaded aperture M
feed slots 20 to the swirl chamber 22. '
‘
In the opening 23 in the bottom of the casing 15
member I‘! there is disposed a nib 24 which is held
in position by the. portions of the casing member
I‘! extending below the nib 24, as .illustrated in
Figure 1, there being set in the nib 24 a hard
stone 25 which is preferably a bort or other dia
mond, but it will be understood that a sapphire,
agate, ruby or any other incorrodible hard stone
may be substituted therefor. As will be seen by
referring to Figure 3 of the drawing, the hard
stone 25 has irregular sides. This hard stone 25
is, therefore, secured in the nib 24 by casting the
nib with the hard stone positioned in the mold
and with the outer face of the hard stone exposed,
as shown in Figure 1. This hard stone 25 has an
ori?ce 26, the nib 24 having an ori?ce, the sides
of which converge downwardly to the inner walls
of the diamond or other hard stone, at its ori?ce
26 forming a continuation of the ori?ce at the
swirl chamber 22 of the nib 24. The hard stone
25 at the outer side of the ori?ce 26 has a sharp
edge 26’ which is preserved during use because
of the character of the hard incorrodible stone
25.
This is important for any wear, erosion or
corrosion of this sharp edge 26' will so enlarge
the ori?ce that it will not properly feed the ?uid.
It will be understood that with this construc
tion the ori?ce 26 of the nozzle will be fashioned
of a material which is incorrodible, and which
when the nozzle is used in a fuel burner will not
corrode, erode or become in any way distorted or
shapeless under the heat from. the ?re box, or
through other causes to which it may be sub
jected. It will also be understood that the slots
20 will maintain their normal size so that the
fuel will be supplied to the slots 20 at all times
in the desired manner, the fuel oil then pass
ing from the ori?ce 26 to the ?re box or furnace.
It will be understood that while the nozzle
which has been described is of particular value
in connection with oil‘burners, it may also be
2

used for a great variety of purposes where it is
important that the ori?ce in the nozzle be made
contact with the head around said whirling
of material which will not corrode‘ or erode, and
that ‘the passages leading to the ori?ce be also
