York, Engineer, for the Invention of “IMPROVEMENTS IN THE CONSTRUCTION
OF WASHING MACHINES, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO

Sealed the 19th December 1879, and dated the 20th June 1879.
PROVISIONAL SPECIFICATION left by the said Thomas Robert Hay Fisken

"IMPROVEMENTS IN THE CONSTRUCTION OF WASHING MACHINES, WHICH IMPROVE-
MENTS ARE ALSO APPLICABLE TO CHURNS."
This Invention relates to certain improvements in the construction of washing
machines, which improvements are also applicable to churns and in giving motion .
to the same.
These improvements are proposed to be carried out as follows:-1 mount upon a
suitable frame a barrel or hollow chamber of any convenient size, into which are
put the materials or articles to be washed or the cream to be churned; this barrel
or chamber can be ribbed or have partitions fixed in the inside in any convenient.
shape or size, and to this barrel or chamber I give a rotatory and reciprocating
motion, or a roundabout, and at the same time a backward and forward motion is
given to it. I impart this double motion to the barrel or chamber by mounting
loosely upon one of the gudgeons of the barrel or chamber a wheel, upon the boss
of which is cast or fixed an eccentric; upon this eccentric a wheel is mounted and
works upon the same, having external teeth upon it; this wheel has an arm cast or
fixed upon its boss extending beyond the wheel; this arm is actuated backwards
and forwards by a connecting rod attached to a crank or eccentric fixed upon the
main motion shaft of the machine. The wheel which works or is mounted upon
the eccentric works or gears into an internal or bosom wheel having a greater
number of teeth in it than the one which works upon the eccentric; this wheel is
mounted fast upon the gudgeon of the barrel or chamber and gives motion to the
same. The first mentioned wheel, which carries the eccentric upon its boss, receives
motion in any convenient way from the power or first motion shaft of the machine.
The machine may be driven by hand or by means of any other motive power,
whichever may be found the most convenient, and the washing machine may have
fixed or attached to it rollers of any convenient size for wringing or mangling.

"IMPROVEMENTS IN THE CONSTRUCTION OF WASHING MACHINES, WHICH IMPROVE-
MENTS ARE ALSO APPLICABLE TO CHURNS."
This Invention relates to certain improvements in the construction of washing
machines or churns, having more particular reference to the method and means of
actuating and imparting motion to washing machines or churns.
The Invention is illustrated on the necompanying Sheet of Drawings in Figures
1 and 2, which respectively represent a front elevation partly in section and an end
elevation of a washing machine or churn as adapted with my present improvements;
Figure 3 represents an enlarged detail view theroof.
1 represents the washing chamber or the churning vessel, which may be made
hexagonal or of any other desired shape and of any convenient size, and may be
fitted in a horizontal, vertical, or other desired position, and may, if required, be
fitted with interior ribs or partitions, or with a “dolly" or "dasker," or otherwise,
as such a chamber or vessel may usually be.
The chamber or vessel 1 is fitted with flanged centres or bushes 2 which are
bolted to the ends thereof, and into which the axles 3, 3*, are inserted and made
fast, the axles passing through and revolving in suitable bearings adapted to or
forming part of the frame 4 of the apparatus.
The axle 3* projects through its bearing for a sufficient distance to carry a spur
wheel 5 provided with a projecting eccentric boss 6 and an internally toothed
wheel 7. The wheel 5, together with its eccentric 6, is mounted loosely upon the
axle 3*, and upon the eccentric 6 is mounted loosely an externally toothed wheel 8
which gears with the wheel 7 which is mounted fast upon the axle 3* and has a
larger number of teeth than the wheel 8.
The wheel 5 receives its motion from a corresponding wheel 9 carried by a stud
or first motion shaft 10 projecting from or mado fast to a convenient part of the
frame 4. Or motion may be otherwise imparted to the excentric 6 by any.
equivalent arrangement for the wheels 9, 5.
The wheel 8 is provided with a projecting arm 11 fast therewith, and the free
end of which is connected by a rod 12 to the wheel 9, as shown, the ends of the
rods 12 working loosely on studs 13 carried by the arm 11 and the wheel 9, the
stud of the latter being prolonged to receive the crank or driving handle 14.
The action of the above described apparatus is as follows:-Motion, being given
to the wheel 9 by means of the handle 14 or by any other convenient means, is
imparted by the eccentric 6 of the wheel 5 in gear therewith to the wheel 8 which
is mounted thereupon; but this wheel is prevented by the arm 11 and rod 12 from
having a circular motion, and is only allowed to have a lateral reciprocating motion
equal to the throw of the eccentric 6, and it is thus caused to impart a rotative
motion to the wheel 7 and consequently to the chamber or vessel 1, and the latter
has simultaneously imparted to it a reciprocating or backward and forward motion
through the action of the rod 12 upon the arm 11 and wheel 8, and which gives
such a motion thereto and to the wheel 7, and consequently to the chamber or
vessel 1.
Thus the chamber or vessel 1 of the washing machine or churn has both a
rotatory progressive motion and a backward and forward motion imparted to it
simultaneously, and by the aid of which combined motions the operations of
washing and churning are much expedited.
In lieu of being driven by hand the machine may be driven by any other
convenient motive power, the first motion shaft being suitably fitted with pullies
or otherwise in lieu of the handle 14,

page_text: Washing machines constructed and adapted as above described may of course be
fitted with wringing or mangling rollers, or with any of the other usual accessories
of such machines.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I would remark in conclusion that I claim as my Invention,―
The application and use in combination in the driving or actuating mechanism
of washing machines or churns of an internally toothed wheel fast on the axle of
the washing or churning chamber or vessel, with an externally toothed wheel
gearing thereinto and mounted loosely upon an eccentric boss projecting from a
spur wheel or its equivalent, mounted loosely upon the said axle and deriving its
motion from a corresponding wheel or its equivalent, mounted on a stud or prime
motion shaft, and deriving its motion from a crank or handle or other suitable
means, the said externally toothed wheel being provided with a 'projecting arm
which is connected by a rod to the first motion wheel or pulley or its equivalent,
the whole being constructed and acting substantially in the manner hereinbefore
described with the object of imparting to the washing or churning chamber or
vessel a rotating progressive motion simultaneously with a reciprocating or back;
ward and forward motion for the purposes hereinbefore stated.
In witness whereof, I, the said Thomas Robert Hay Fisken, have hereunto set
my hand and seal, this Tenth day of December, in the year of our Lord
One thousand eight hundred and seventy nine.
