I, LEOPOLD UNGвB, of Bonn, in the Kingdom of Prussia, at present
temporally resident at the office for Patents, 123, Chancery Lane, London, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE CON--
STRUCTION AND ARRANGEMENT OF Box IRONS USED BY LAUNDRESSES AND OTHERS FOR
PRESSING AND SMOOTHING CLOTHES AND FABRICS," to be as follows:-
My Invention relates to improvements on that class of ironing imple-
ments generally known as "box irons" used by laundresses and others. 1-

on pivots each side can be used alternately. F attach to the iron a small lamp
of any suitable construction supplied with wick, oil, naptha, or other heating
medium to convey heat to the interior of the iron instead of red-hot heaters-

The construction of my said Invention will be clearly understood by
reference to the accompanying outline Drawing, in which Fig. 1 is a side view

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LEOPOLD
UNGER, of Bonn, in the Kingdom of Prussia, at present temporarily resident
at the Office for Patents, 123, Chancery Lane, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent bearing date the Seventeenth day of July, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me
the said Leopold Unger, Her special licence that I, the said Leopold
Unger, my executors, administrators, and assigns, or such others as I, the
said Leopold Unger, my executors, administrators, and assigns,-should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN THE CONSTRUCTION AND ARRANGEMENT OF BOX IRONS USED BY LAUN-
DRESSES AND OTHERS FOR PRESSING AND SMOOTHING CLOTHES AND FABRICS," upon
the condition (amongst others) that I, the said Leopold Unger, my execu-
tors or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Leopold Unger, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement (that is to say):-
My Invention relates to improvements in that class of implements generally
known as box irons, used by laundresses and others, and consists of making
the top and bottom parts of the iron with smooth surfaces, having round,
curved, or pointed noses as may be required for the particular kind of articles
to be ironed. In the back of the iron I bore or otherwise make a hole and
fit it upon the boss of the handle so that the iron can be turned round and
the two flat surfaces used alternately. I also attach to the iron a small lamp
of any suitable construction in order to convey heat to its interior, instead of

page_text: employing red-hot heaters as hitherto used. The lamp is furnished with a
wick, and supplied with oil, naptha, or other combustible material, and the
sides of the iron are perforated with holes for the purpose of maintaining
combustion by the circulation of air.
These improvements will be clearly understood by reference to the figures
and letters on the accompanying Sheet of Drawings, in which Fig. 1 is a side
view of the iron with the lamp attached; Figs. 2 and 3 back and front views of
the same, without the lamp; Fig. 4, a perspective view shewing the iron partly
turned in its bearing, and Fig. 5 a longitudinal section of the iron having the
lamp attached and shewing the flame in the interior. The smooth exterior sur-
faces of the top and bottom of the iron are shewn at a and b, and at the back of
the iron is the hole c which fits the boss d of the handle e, so that the iron can be
turned upon it, and the smooth surfaces a and b used alternately. Attached
to the iron is the small lamp f having a tube 9 to hold the wick, which tube
is placed through a hole in the boss of the handle, so that the flame his
passed into the interior of the iron and gives it the necessary heat, there being
in the sides and ends of the iron the holes k for the circulation of air.
This improved system of heating may also be applied to the ordinary box
iron with one smooth surface only, by passing a flame into the interior, and
making holes in the sides for the circulation of air.
Having now described the nature of my said Invention, and the manner in
which the same is to be performed, I desire it to be understood that I claim
the general arrangement and construction of box irons as herein described
and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Leopold Unger, have hereunto set my
hand and seal, this Fourteenth day of January, in the year of our
Lord One thousand eight hundred and sixty-one.
LEOPOLD UNGER. (L.s.)

named Leopold Unger, in the presence
