IMPROVEMENTS IN WASHING MACHINES
Year: 1872

page_text: LETTERS PATENT to William Hook Davey, of Islington, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN WASHING
MACHINES."
Sealed the 10th October 1872, and dated the 23rd April 1872.
PROVISIONAL SPECIFICATION left by the said William Hook Davey
at the Office of the Commissioners of Patents, with his Petition,
on the 23rd April 1872.
I, WILLIAM HOOK DAVEY, of Islington, in the County of Middlesex,
5 do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
WASHING MACHINES," to be as follows:-
My Invention relates to improvements in washing machines such as
those for which I obtained Letters Patent bearing date the 30th June
1865, No. 1774.
In the Specification of the said Patent the washing vessel is described
as being of wood for the most part. Now according to my present

page_text: Invention I construct the ends of the said vessel each of a galvanized
iron plate cast with ribs on the inner surface, which form grooves to
receive the front and back top board and other parts, the two ends
being secured together by bolts running lengthwise of the vessel and
firmly securing the whole together. These bolts pass through projecting ☐
sockets cast on the end plates. These plates also carry the bearings in
which the rocking shaft is mounted. Instead of making the bottom
of the vessel square, and filling in the corners with wooden blocks, I
make the bottom of the vessel of a curved form both inside and outside,
whereby any accumulation in the corners of the vessel is avoided, and
I also line the interior surface with a corrugated sheet of galvanized
iron to form the roughened surface required to produce the necessary
friction on the clothes or material under operation, or I line the bottom
with a number of half round galvanized iron bars laid side by side
with the same object. These bars are first riveted close together to
metal straps curved to the shape of the bottom of the vessel to which
the said straps are then secured, the metal bars being.disposed lengthwise
in the vessel..
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Hook Davey in the Great Seal Patent
Office on the 23rd October 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HOOK DAVEY, of Islington, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of April, in the year:
of our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Hook Davey, Her special licence
that I, the said William Hook Davey, my executors, administrators, and
assigns, or such others as I, the said William Hook Davey, 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

Figure 1 is a perspective view of the machine, Figure 2 represents
a cross section of the same drawn to a somewhat larger scale.
A, A, are the two end plates of galvanized iron cast with ribs a on
the inside to form grooves in which the ends of the front, back, and 5
top boards are received, and with lugs b, through which the bolts c
pass, by which the whole of the parts are firmly held together. A
bracket & is also cast on each plate to support the driving shaft.
By the use of metal plates I am enabled to make the grooves curved
at the lower part, so that the bottom of the vessel is rounded both.10
inside and out, thereby leaving no corners to be filled in with blocks
which tend to accumulate dirt; e is a corrugated sheet of galvanized.
iron with which the vessel is lined, being firmly fixed thereto by
bolts c¹. It is soldered at the edges to the end plates A to prevent the
water getting beneath it, and the top edges are soldered to a metal 18
bar e¹ fixed against the inside of the vessel with the same object.
I have only shown one half of the vessel lined with corrugated metal.
but it will be understood that the whole of the vessel will be so lined,
or instead of a sheet metal lining I may use a number of half round
galvanized iron bars as at S, Figure 2, arranged longitudinally in the 20
vessel and riveted side by side to metal straps, also galvanized and
curved to the shape of the bottom, in which they are placed as shown.
The beaters are constructed and operated as in the machine previously
patented by me before referred to, and the sloping top and shoot boards
and the hinged front are all arranged as before. Instead of mounting 2
the crank ping in a radial slot in the disc h in which the pin g tends
to work loose, I provide a number of holes i in the disc at various
distances from the centre, in any one of which the crank pin may be
readily fixed according to the radius necessary to give the desired throw
to the crank.
Having described the nature of my Invention, and in what manner
the same is to be performed, I declare that what I claim as my Inven-
tion to be protected by the herein-before in part recited Letters Patent.
is,--

1st. The construction of a washing machine of the description ·herein” 3

page_text: referred to, with end plates of metal cast with grooves on the inner
surface and secured together by longitudinal bolts passing through lugs,
all substantially as described and shown, and for the purpose specified.
2ndly. Lining the bottom of the washing vessel with a corrugated'
sheet of metal, or with a series of half round metal bars, substantially as
shown and described.
In witness whereof, I, the said William Hook Davey, have here-
unto set my hand and seal, this Twenty-second day of October,
in the year of our Lord One thousand eight hundred and seventy-
two.
