PROVISIONAL SPECIFICATION.
Improvements in Washing Machines.
I, GEORGE WILLIAM GRAYSTON of Three Tuns Brewery Linton Cambridge,
Brewer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to form a machine for washing linen and like
articles.
For this purpose I construct a frame of suitable material preferably of wood
consisting of a top and bottom rail, between which, two parallel uprights are firmly
affixed at or near each end. These uprights are grooved on their inner faces for
the whole or part of their length in which, blocks or slides are made to fit. These
sliding blocks carry the spindles of a curved brass plate or cover containing any
This
required number of rollers which are pivotted to the end plates of same.
plate or cover, and its contained rollers are pressed into close contact with the
upper surface of a larger roller having V shaped grooves cut upon it, by means of
spiral or other springs placed where required."
The larger or grooved roller is mounted on a spindle working in suitable bearings
on the uprights, to one end of which a cranked handle is affixed. The whole is
fitted in a shallow tub by slides or other methods or it may be affixed to any
suitable vessel by screws or clamps. The framework should be fitted together
preferably by means of thumbscrews or nuts and bolts. In use the linen or other
like articles are passed between the rollers until sufficiently cleansed.
Dated this 9th day of May 1891.

Improvements in Washing Machines.
I, GEORGE WILLIAM GRAYSTON of Three Tuns Brewery Linton Cambridge
Brewer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The object of this invention is to form a simple, durable and efficient machine
for the rapid cleansing of soiled linen, underclothing and like articles.
For the carrying out of my invention, I construct a stout framing of any suitable
size and material, but preferably of wood, said frame being formed of two parallel
uprights and one or more cross bars or struts, all firmly bolted together at or near
their ends, preferably by means of bolts and fly-nuts. The uprights are grooved or
slotted, for the whole or any part of their length, to receive metal or other blocks
fitted to slide therein; said sliding blocks being constructed to carry the spindles
or pivots of two curved metal plates or covers, in which the ends of any required
number of small wooden rollers are pivotted to revolve freely. These curved plates
or covers and their contained rollers, are pressed into close contact with the upper
surface of a larger V fluted or corrugated roller or drum by means of spiral or
other suitable springs placed where required. The larger V fluted or corrugated
roller is mounted on a spindle working in suitable bearings on the uprights and to
one end of which a cranked handle is affixed. The whole is fitted in a shallow tub
by slides or other method or it may be affixed to any suitable vessel by screws or
clamps.

page_text: That my invention may be the better understood I have hereunto annexed a
sheet of illustrative drawings in which :-
Fig. is a front elevation of the apparatus, a portion of the tub being broken
away and
Fig. 2 a side elevation of the same;
Fig. 3 is an edge view of part of the tub shewing one method of securing the
uprights thereto; and
Fig. 4 a cross section of one of the uprights shewing the sliding block and
grooves.
Like letters indicate corresponding parts in all the figures.
a is the tub to which the slotted uprights bare firmly clamped or bolted in any
convenient manner, said uprights being connected by the crosspiece c which is
firmly bolted to them as shewn at d. d.
For additional stability a second crosspiece or stay may be used if desired either
at the lower extremities of the uprights or in any position below the roller e.
Between the aforesaid uprights, at any convenient height but preferably just below
the rim of the tub, a large V fluted, or corrugated wooden roller e is pivotally
mounted on a spindle running in any suitable bearings. To one end of this
spindle a cranked handle g is keyed or otherwise affixed.
In the slotted portions of the uprights blocks are fitted to slide, to which
the curved plates ii are pivotally connected. Pivotted to these curved plates i i
are the small loose rollers j. j. preferably five in number, which are kept in close
contact with the upper surface of the V fluted or corrugated roller e by the pressure
of the spiral springs k. is a slotted metal plate which can be slipped over the
spindle as shown in the drawing, to keep the machine steadier when in use.
Fig. 3 shows a convenient method of fixing the uprights to the inside of the
tub a.
Where required bent metal plates m. m. preferably of galvanized iron, are
affixed to grip the upright, said plates being of any length required to provide a
firm hold for the uprights.
Fig. 4 is a cross section of one of the uprights showing a convenient form for the
grooves and the sliding blocks.
The framework of the machine being fitted together with bolts and fly-nuts, can
be easily taken to pieces at any time for cleaning, repairs, or like purposes.
I wish it understood that I may alter some of the minor details of construction,
and use other suitable materials than those above mentioned in my machine if
desired, I may also fit the same on any other description of tub than the one
illustrated, without departing from the nature of my said invention.
In using my apparatus the soiled linen or other articles to be cleansed are passed
between the large roller e and the small rollers j. j. in lieu of rubbing the same with
the hands as heretofore until sufficiently cleansed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
A machine for washing linen and the like consisting of a suitable framework in
which a fluted or other roller can be rotated by any suitable driving mechanism.
such roller acting in conjunction with other smaller rollers, pivotted to curved plates
and acted upon by the pressure of spiral or other springs all substantially as
hereinabove specified and as illustrated in the drawings.
