1, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
The hand or power washing machine constructed according to this invention is
based essentially on the principle of keeping the articles in the wash-drun or barrel
in constant movement to and fro against each other and against the sides and
partitions of the drum.
This object is attained by means of a rocking sector lever suitably mounted on
one side of the frame with a toothed sector engaging in a toothed wheel keyed on
the drum shaft.
The lever being caused by the driving or motive power to rscillate communicates
the movement to the drum which is thereby rocked to and fro upon its axis in
alternate revolutions.
The machine can be worked either by a crank handle on a fly-wheel or by a
belt-pulley secured to the same shaft. A spur pinion fixed on the latter engages
with the wheel on another shaft on which is secured a crank-arm which is thereby
rotated and in its turn by means of a connecting rod jointed to the ends of the
crank arm and the sector lever establishes the rocking motion of the latter and with
it of the washing drum.
Inasmuch as by this construction the periphery of the rocking sector being
equal to that of the pinion driven by it, the drum constantly makes a complete
revolution in one direction, followed by a complete revolution in the opposite
direction, all the conditions are established which are essential as the basis of the
thorough and efficient working of a washing-machine.
The wash-liquor or suds thoroughly rinse, penetrate and cleanse the articles to
be washed and its detergent action is necessarily as intimate and complete as it is
possible to conceive; while on the other hand the entanglement and twisting of the
linen which inevitably result in all those washing machines in which a consecutive
series of revolutions in one direction are succeeded by another such series in the
opposite direction, are almost or entirely prevented.
Experience teaches that exceptionally fine fabrics such as curtains etc. suffer
great and frequent injury from the rough treatment to which they are subjected
in the washing machines at present in use and not seldom are rent in two length-
wise by being caught fast between two entangled and twisted balls or rolls of
washing.
It is obvious that this is avoided with a machine in which the articles fall to
and fro by single alternations.
The rocking motion of the sector lever may, by a connecting rod, be transmitted
to a similar lever of a second machine to be worked in combination therewith so as
to impart the necessary alternating revolutions to its drum.
This latter arrangement is specially adapted for use in power machines.

of Works, both of Hannover-Linden, in the Empire of Germany.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, 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 hand or power washing-machine constructed according to this invention as
shown respectively in elevation and plan in Figures 1 and 2 of the accompanying
drawings, is based essentially on the principle of keeping the articles in the wash-
drum or barrel in constant movement to and fro against each other and against the
sides and partitions of the drum.
This object is attained by means of a rocking lever, suitably pivoted at on
one side of the frame, with a toothed sector engaging in a toothed wheel keyed
on the drum-shaft w.
The lever being caused by the driving or motive power to oscillate, com-
municates the movement to the drum which is thereby rocked to and fro upon its
axis, in alternate revolutions.
The machine can be worked either by a crank-handle on a fly-wheel R or by a belt-
pulley secured to the same shaft w¹. A spur pinion fixed on the shaft w
engages with the wheel on another shaft on which is secured a crank-arm K
which is thereby rotated and in its turn, by means of a connecting rod y jointed to
the ends of the crank-arm K and the sector-lever establishes the rocking motion
of the latter and with it of the washing-drum t.
Inasmuch as by this construction the periphery of the rocking sector = being
equal to that of the pinion : driven by it, the drunt constantly makes a complete
revolution in one direction followed by a complete revolution in the opposite direction,
all the conditions are established, which are essential as the basis of the thorough
and efficient working of a washing-machine.
The wash-liquor or suds thoroughly rinse, penetrate and cleanse the articles to
be washed and its detergent action is necessarily as intimate and complete as it is
possible to conceive; while on the other hand the entanglement and twisting of the
liuen which inevitably result in all those washing machines in which a consecutive
series of revolutions in one direction are succeeded by another such series in the
opposite direction, are almost or entirely prevented.
Experience teaches that exceptionally fine fabrics such as curtains etc. suffer
great and frequent injury from the rough treatment to which they are subjected
in the washing machines at present in use, and not seldom are rent in two length-
wise by being caught fast between two entangled and twisted balls or rolls of
washing.
It is obvious that this is avoided with a machine in which the articles fall to and
fro by single alternations.
Figure shows in dotted lines an arrangement for transmitting the rocking
motion of the lever by a connecting rod v to a similar lever and a second
toothed sector and pinion 5 of a second machine to be worked in combination
therewith so as to impart the necessary alternating revolutions or oscillations to its
drum t'.
This latter arrangement is specially adapted for use in power machines.

page_text: Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondents, and in what
manner the same is to be performed, I declare that what I claim is ;-
1. In a washing machine a pivoted toothed sector engaging with a toothed
wheel on the drum shaft w and having a lever arm h connected by a connecting
rod g with a crank arm K so that the rotary notion of the crank arm K generated
by means of a train-gear fly wheel and crank-handle or a belt-driven pulley or
equivalent causes the toothed sector to be oscillated whereby the toothed wheel z¹
and therewith the drum are also oscillated substantially as described and
illustrated in the accompanying drawings.
2. The combination with a washing machine such as set forth in the preceding
claim of a second toothed sector lever arm link toothed wheel 2" and a
second drum t arranged so as to operate in conjunction with the first drum and
its appurtenances substantially as described and illustrated in the accompanying
drawings.
3. The combination and arrangement of parts constituting the complete washing
machine substantially as described and illustrated in the accompanying drawings.
Dated this 25th day of March 1895.
