A NEW OR IMPROVED WASHING MACHINE
Year: 1875

page_text: LETTERS PATENT to Peter Jensen, of Chancery Lanc, London, for
the Invention of "A NEW OR IMPROVED WASHING MACHINE." -A com-
munication from abroad by Auton Bohlken, of Varel, Oldenburg,
Architect.
Scaled the 25th March 1875, and dated the 26th January 1875.
PROVISIONAL SPECIFICATION left by the said Peter Jensen at
the Office of the Commissioners of Patents, with his Petition, on .
the 26th January 1875.
I, PETER JENSEN, of Chancery Lane, London, do hereby declare the
nature of the said Invention for "A NEW OR IMPROVED WASHING MACHINE,"
(a communication to me from abroad by Autou Bohlken, of Varel,
Oldenburg, Architect,) to be as follows:-
Washing machines constructed according to this Invention arc as
follows: The water and the clothes are contained within a hollow
cylinder or cask, which is made with longitudinal ribs inside. It is by
preference made of an outer barrel of wood and an internal ribbed lining

page_text: of wood, and with a space between the two, which space is filled with
some non-conducting material in order better to retain the heat. One
end or bottom of the said cask or cylinder is fixed water-tight and the
other bottom is made to open or take off and to close water-tight after
the water and the clothes have been put in. The cask or cylinder
contains inside a loose heavy roller having ribs corresponding with the
aforesaid ribs of the cylinder and of a diameter, say, two thirds of that
of the inside of the cylinder. The roller is by preference made of ribbed
zinc or copper and filled in with cement. The cylinder is by a central
gudgeon on each side hung in an oval hoop, which at each end has a
gudgeon fitting in bearings on a frame, and by means of a handle or
fly wheel can be made to revolve; when thus in motion the heavy inside
roller exerts a constant pressing and kneading action on the clothes.
A wringing machine may conveniently be placed on the same frame.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Peter Jensen in the Great Seal Patent Office on
the 24th July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
JENSEN, of Chancery Lane, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of January, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Peter Jensen, Her special
licence that I, the said Peter Jensen, my executors, administrators,
and assigns, or such others as I, the said Peter Jensen, 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 "A NEW OR
IMPROVED WASHING MACHINE," (a communication to me from abroad by
Auton Bohlken, of Varel, Oldenburg, Architect,) upon the condition.
(amongst others) that I, the said Peter Jensen, my executors or admi-

page_text: ṇistrators, 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 performed, 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 Peter Jensen, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying
Drawings, and to the letters of reference marked thercon, that is to.
say:―
Washing machines constructed according to this Invention are as
follows: The water and the clothes are contained within a hollow
cylinder or cask, which is made with longitudinal ribs inside. It is by
preference made of an outer barrel of wood and an internal ribbed lining
of wood, and with a space between the two, which space is filled with
some non-conducting material in order better to retain the heat. One
end or bottom of the said cask or cylinder is fixed water-tight, and the
other bottom is made to open or take off and to close water-tight after
the water and the clothes have been put in. The cask or cylinder
contains inside a loose heavy roller having ribs corresponding with the
aforesaid ribs of the cylinder, and of a diameter, say, two thirds of that of
the inside of the cylinder. The roller is by preference made of ribbed ziņc
or copper and filled in with cement. The cylinder is by a central
gudgeon on each side hung in an oval hoop, which at each end has a
gudgeon fitting in bearings on a frame, and by means of a handle or fly
wheel can be made to revolve; when thus in motion the heavy inside
roller exerts a constant pressing and kneading action on the clothes.
A wringing machine may conveniently be placed on the same frame.
And in order that this Invention may be more fully ascertained and
understood, I will now proceed to describe the same, with reference to
the accompanying Drawings, of which Figure 1 is a side elevation of
a washing machine constructed according to this Invention; Figure 2,
a vertical cross section through same; and Figure 3, a side clevation,
showing the washing cylinder or cask in a different position to that shown
at Fig. 1.

page_text: The water and clothes are contained within a hollow cylinder or cask A,
which is made with longitudinal ribs inside; it is here shown in its
simplest form, viz., with a simple wall of ribbed wood staves held
together by hoops a. One end or bottom of the cylinder A is fixed
watertight, and the other bottom B is made to open or take off; it is in
this case attached by means of hinges. After the water and the clothes
have been put in it is closed watertight by tightening up the set screw c,
which passes through the hinged clamp d; C is the inside loose heavy
roller, having ribs corresponding with the ribs on the inside of the
cylinder. This latter is by a central gudgeon at e on cach side hung in
an oval hoop D, which at each end has a gudgeon f fitting in bearings
on a frame E, E; F is a hand wheel for turning the hoop D and tho
cask A carried by it. When the clothes and water are put in and the
machine thus put in motion the heavy roller C exerts a constant pressing
and kneading action on the clothes.
Fig. 3 shows the position of the cask A convenient for putting in
the water and clothes and for closing the cask.
And having thus fully described this Invention, and how it is or may
be carried into effect, I declare that I claim,-
Firstly. A washing machine consisting of a revolving cask with inner
ribbed surface and a heavy inner loose ribbed roller operating sub-
stantially as set forth.
Secondly. The cask A in combination with the hoop D and roller C.
Thirdly. The construction of the cask A, viz., with one end to open
with ribs on the inside, and with or without the intervening layer of
non-conducting material.
In witness whereof, I, the said Peter Jensen, have hereunto set
my hand and seal, this Fourteenth day of July, in the year of
our Lord One thousand eight hundred and seventy-five.
