page_text: LETTERS PATENT to Gerard Wenzeslaus von Nawrocki, Proprietor of the
firm of J. Brandt & G. W. v. Nawrocki, Patent Solicitor and Civil
Engineer of 124, Leipzigerstrasse, Berlin, Germany, for an invention of
PROVISIONAL SPECIFICATION left by the said Gerard Wenzeslaus von
Nawrocki at the Office of the Commissioners of Patents on the 4th May
1882.
GERARD WENZESLAUS VON NAWROCK! Proprietor of the firm of J. Brandt &
G. W. v. Nawrocki Patent Solicitor and Civil Engineer of 124 Leipzigerstrasse,
Berlin, Germany. "IMPROVEMENTS IN AND CONNECTED WITH IRONS ESPECIALLY
APPLICABLE TO BOX IRONS HEATED BY GAS." (A communication from Arnold
Brecher of New York, United States of America).
This invention refers to such irons in which the iron proper or box is jointed to
the handle by a leg descending from the latter. The improvements consist in a
mode of attaching the iron proper or box to the handle, in the employment of a
goffering or crimping roller on the iron and of a goffering or crimping plate used
in connection with such an iron, and lastly in the appliances for heating the iron.
As regards the mode of connecting the handle to the iron proper this has
heretofore been done in a one-sided manner that is only by one leg of the handle
or one end of the iron, so that in course of time the connection between handle
and iron gets loose. According to this invention however the fixing is effected by
pivots at both ends of the iron and so that by simply pressing with the thumb on an
arm connected to the handle the iron becomes disconnected so that it can be turned
round quickly, while it never becomes loose.
The iron is hollow or box formed and has a gudgeon at each end, one of them is
solid, and the other is hollow for introducing the heating appliance. On one of

page_text: the curved sides of the iron an aperture is formed in which is mounted a tooth
wheel like goffering or crimping roller. The other side serves for smoothing or
polishing. The flat top and bottom of the iron are used for ironing. The iron is
made to take four different positions relatively to the handle, which latter can be
fixed in any of the four positions. For this purpose the solid end gudgeon is
formed on its end with two incisions or notches at right angles to each other
forming thus four notches and four intermediate lugs, and the nave or boss of the
leg of the handle fitting on this gudgeon is formed with a notch into which the
lower end of a lever can be inserted, this lever has its fulcrum on the leg and its
lower end is by a spring held into the said notch of the lever and into one of the
four notches in the end of the solid gudgeon thus fixing the handle in position
relatively to the iron. The handle is connected to the opposite end of the iron by
a descending leg which has an eye or nave around the hollow gudgeon and is fixed
thereto by a sliding bolt the lower end of which by a spring is pressed through a
hole in the nave of the leg and through one of four holes formed in the hollow
gudgeon which holes correspond with the four notches in the end of the other
gudgeon.
The heating appliance consists of a burner which is supplied by a pipe from a
reservoir. The fuel used is spirits on a volatile hydrocarbon the supply being
regulated by a needle pointed valve as in an injector. The burner itself consists
of a socket screwed on to the end of the supply pipe the point or end of which
projects into the socket which has lateral holes for air admission as in the "Bunsen'
burner. The supply pipe is bent so that its bend is opposite to and is heated by
the flame from the burner, whereby the volatile liquid is volatilized and mixing
with air comes to the place of ignition where it heats the iron but this combustion
takes some minutes after lighting the burner before it is properly established. The
products of combustion escape by openings in the sides of the iron.
For goffering or crimping the aforesaid roller is used in combination with a
plate on to which the material to be goffered or crimped is placed; this plate is
formed with teeth sharp or rounded and corresponding with the teeth on the
roller which is heated from the burner and rolled over it thus forming the material
with the required goffers or crimps.

by the said Gerard Wenzeslaus von Nawrocki in the Great Seal Patent
Office on the 4th November 1882.
GERARD WENZESLAUS VON NAWROCKI Proprietor of the firm of J. Brandt &
G. W. v. Nawrocki, Patent Solicitor and Civil Engineer of 124 Leipzigerstrasse
Berlin Germany "IMPROVEMENTS IN AND CONNECTED WITH IRONS ESPECIALLY
APPLICABLE TO BOX IRONS HEATED BY GAS. (A. communication from Arnold
Brecher of New York, United States of America).
This invention refers to such irons in which the iron proper or box is jointed to
the handle by a leg descending from the latter. The improvements consist in a
mode of attaching the iron proper or box to the handle in the employment of a
goffering or crimping roller on the iron and of a goffering or crimping plate used in
connection with such an iron, and lastly in the appliances for heating the iron.
As regards the mode of connecting the handle to the iron proper this has
heretofore been done in a one sided manner that is only by one leg of the handle
or one end of the iron, so that in course of time the connection between handle
and iron gets loose. According to this invention however the fixing is effected by
pivots at both ends of the iron and so that by simply pressing with the thumb on
an arm connected to the handle the iron becomes disconnected so that it can be
turned round quickly, while it never becomes loose.
In the accompanying drawings Figure 1 represents a side view of the iron,
Figure 2 is a vertical longitudinal section through same and Figure 3 a plan
section. Figure 4 is a plan and Figure 44. a longitudinal section of a goffering
plate used in connection with the iron. Figure 5 and 6 are vertical longitudinal
sections of modified constructions.
The iron is hollow or box formed and has a gudgeon at each end, one of
them a is solid, and the other b is hollow for introducing the heating appliance.
On one of the curved sides of the iron an aperture d is formed in which is mounted
a tooth-wheel-like goffering or crimping roller f. The other side g serves for
smoothing or polishing. The flat top and bottom c of the iron are used for ironing.
The iron is made to take four different positions relatively to the handle, which
latter can be fixed in any of the four positions. For this purpose the solid end
gudgeon a is formed on its cud with two incisions or notches at right angles to
cach other forming thus four notches and four intermediate lugs and the nave or
boss of the leg m of the handle h fitting on this gudgeon is formed with a notch
into which the lower end of a lever can be inserted, this lever has its fulcrum i on
the leg m and its lower end is by a spring n held into the said notch of the lever m
and into one of the four notches in the end of the solid gudgeon a thus fixing the
handle in position relatively to the iron. The handle h is connected to the opposite
end of the iron by a descending leg p which has an eye or nave around the hollow
gudgeon band is fixed thereto by a sliding bolt o the lower end of which by a
spring is pressed through a hole in the nave of the leg p and through one of
four holes formed in the hollow gudgeon b which holes correspond with the four
notches in the end of the other gudgeon a.
Figure 5 shews a modification of this arrangement. The two springs are in this
case superseded by a single spring m¹ placed in the hollow handle g and acting
against a collar washer or projection, provided on the rod s: this spring causes the
lever and the bolt o to be locked, the latter being connected to the rods by the
bell crank levers q; the vertical arm of which works in an eye s¹ in the rod 8.
The whole of this arrangement forms a mechanism in which the spring is not so
much exposed to heat.

page_text: The heating appliance consists of a burner t which is supplied by a pipe u from
a reservoir w. The fuel used is spirits or a volatile hydrocarbon the supply being
regulated by a needle pointed valve v as in an injector. The burner itself consists
of a socket screwed onto the end of the supply pipe u the point or end of which
projects into the socket which has lateral holes x for air admission as in the
"Bunsen" burner. The supply pipe u is bent so that its bend is opposite to and
is heated by the flame from the burner t whereby the volatile liquid is volatilized
and mixing with air comes to the place of ignition where it heats the iron
but this combustion takes some minutes after lighting the burner before it is
properly established. The products of combustion escape by opening y in the
sides of the iron.
Figure 6 shews a modified arrangement of the heating appliance. The pipe u
is so bent and provided with a second valve v₁ that the position of the fluid in the
lower part of the tube u can be regulated, so that no liquid fuel can come to the
valve v but the evaporation only takes place in the bend of the tube u in front of
the burner t.
The screw v². serves to regulate the valve v¹.
The heating appliance is as shewn at Figures 1, 2, and 5 fixed to the leg p by
means of a peg r¹, in such a manner that it reaches into the interior of the iron.
For goffering or crimping the aforesaid roller f is used in combination with a
plate z Figures 4 and 44., on to which the material to be goffered or crimped is placed;
this plate is formed with teeth sharp or rounded and corresponding with the teethi
on the roller which is heated from the burner and rolled over it thus forming the
material with the required goffers or crimps.
I claim as the invention communicated to me.
First In irons, in which the box can turn, the combination of the lever and
bolt o for simultaneous fixing of the box to the legs m and p. and the simultaneous
connecting and disconnecting of the same by means of bell crank lever q and rod s
acted upon by the springs n and r.
Second: In irons, in which the box can turn, the simultaneous disconnecting
and connecting of the lever and the bolt o by means of the bell crank lever q
