We EMIL EHRICH and ALBERT GRAETZ, trading under the name of "Ehrich
& Graetz, Lamp Manufacturers of N° 82 & 83 Dresdener Strasse in the City of
Berlin and German Empire do hereby declare the nature of our Invention for
IMPROVEMENTS IN HYDRO CARBON LAMPS and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement:
Our invention relates to improvements in hydro carbon lamps with more than
one wick combined so as to form a circular wick at the upper edge of the wick
sheaths, with a special device for clamping the said wick to the slides, with a
vertical moveable double slide, with a novel arrangement of the air feed to the
flame and with a flame deflector and air distributor inserted in the central air
conducting tube.
As is well known to those acquainted with this special branch of industry the
chief points to be attended to if a lamp is to produce perfect combustion is the air
supply, the correct distribution of the air supply to all parts of the wick, keeping
the wick in such condition that it will not readily get clogged and assuring the
readily vertical movement of the same in the wick sheath. Now all these points
have been most carefully considered in the present construction and a lamp
produced which emits a most brilliant light.
Figure 1 is a vertical section of our improved burner.
Figure 2 a horizontal section on the line xx in Fig. 1.
Figure 3 is a vertical section of the wick sheath with the inner tube and
reciprocating slide in elevation.
Figure 4 is an elevation of the combined deflector and air distributor.
Figure 5 is a section of the same on the line y y in Figure 4.
Figure 6 is a vertical section of the flame deflector and air distributor.
Fig. 7a horizontal section on the line zz in Fig. 6; Figure 8 is an elevation of
the reciprocating double slide with the rack attached in the centre of the same.
Figure 9 is a view of the under surface of the same showing the manner in
which the ends of the wires for forming the clamps are soldered to the lower disc
so as to produce the requisite spring action of the said clamps.
Figure 10 is an elevation of our improved burner and Fig. 11 a top view of the
same showing the perforated flange to the burner cap for conducting heated air to
the external surface of the wick.
a is the outer partly perforated casing of the burner with the gallery or chimney
holder b. c is the ring attached to the reservoir or hydro carbon receptacle and
which is provided with female screw threads to receive the burner. d is the cap
provided with the air holes or perforations u and in the upper flange of the said
cap with the air holes or perforations v.
e and f are the wick sheaths which are arranged at an incline to each other so
that a slot tapering to nothing at the upper end where the sides of the two sheaths
come in contact with each other is formed whereas the said shienths stand about an

page_text: eighth of an inch apart at the lower end-g g is a double cap with connecting
pieces g¹ fitted over the upper ends of the two wick sheaths and soldered to the
same in order to firmly press the edges of the said wick sheaths together. h is a
horizontal disc arranged between the two wick sheaths; the same is slotted in the
centre to receive the rack q of the double slide p the upper end of the said rack
being provided with a small knob or with a drop of solder to prevent its leaving
the said slot whereas the lower end is firmly soldered to a disc a forming the con-
nection between the two halves of the double slide p and also the base of the same.
i is a small flanged tube which serves to support the combined flame deflector and
air distributor; k is the tube which is slotted at m and is provided with the
wings to the inner ends of which the stem n of the flame deflector o is fixed;
pp are the two vertical slides which are connected by the disc x, Fig. 9, and can
be moved up and down by means of the rack q and pinion r which latter are held
in position on the wire to the key y by means of the bearings 8. tt are the wicks
-u the perforations in the wall of the cap d whereas v are the perforations in the
upper flange of the cap d.
ww are the small wire clamps for clamping the wick to the slide which said
slide is reciprocated by means of the rack and pinion q r so that the wick can
under no circumstance be injured by the grip of the pinion as is customary in
most lamps.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1. In a bydrocarbon burner the combination of the cap d provided with the
perforations u and v with the two wick sheaths e and f and the cap g to the
same substantially as described in the foregoing specification and shown in
the accompanying drawings.
2. In a hydrocarbon burner the arrangement construction and employment of
the combined flame deflector no and air distributor k ml substantially as and for
the purpose set forth in the foregoing specification and shown in the accompanying
drawings.
3. In a hydrocarbon burner the combination of the two wick sheaths ef with
the double slide p p, the rack q, pinion r and the flame deflector and air distributor
substantially as and for the purpose set forth in the foregoing specification and
shown in the accompanying drawings.
4. In a hydrocarbon burner the combination of the clamping device w for
clamping the wick to the slides p p and thus preventing the wick being injured
by the grip of the pinion the wire of which said clamps are composed or to which
they are affixed being so put under torsion that the wicks are firmly held in
close contact with the slides with the double sheaths ef and the flame deflector 4
and air distributing device substantially as described in the foregoing specification
and shown in the accompanying drawings.
5. In a hydrocarbon burner the general construction combination and arrange-
inent of the parts substantially as set forth in the foregoing specification and shown
in the accompanying drawings.
