PROVISIONAL SPECIFICATION.
Improvements Appertaining to Driving Mechanism for Domestic
Washing Machines.
I, JOSEPH MATTHEW SELLERS, of the Firm of W. Sellers and Sons, of Keighley,
in the County of York, Machine Makers, do hereby declare the nature of this
invention to be as follows, that is to say:-
It relates to means for transmitting rotary motion to the dollying mechanism
of domestic washing machines of the class wherein the said mechanism is mounted
upon so as to be carried by the lid or cover of the box or receptacle, in which
the clothes to be washed are placed, and my said invention consists in construct-
ing and arranging said mechanism so that, while the rotary motion is trans-
mitted thereto for a certain period in one direction and a like period in the
opposite direction, the dolly in the box or receptacle may act at any desired
position or height in said box or receptacle as the quantity or bulk of the clothes
may determine.
In carrying my invention into effect we form the dolly's shaft square (or
other shape than circular) in cross-section so that it may slide through the
coupling piece for securing it to one or other of its driving wheels and yet
at any position therein said coupling piece may transmit the motion desired
to it. To enable me thus to make use of a square shaft I construct the bearings
for such shaft to receive bushes with holes for the dolly's shaft to pass through
them of a shape corresponding with that of said shaft, by which means when
the shaft rotates it carries its bushes with it to rotate in their bearings.
Instead of these bushes being used, a circular shaft having a keyway formed
in it to receive the key on the coupling piece, may be employed.
The hinged coupling lever already made use of may either be put into or put
out of gear with its wheels, by the incline piece at present in use or I may
form one wheel to move said lever from being coupled with the other and so
dispense with the stationary incline pieces.
In place of the coupling lever usually made use of I mount a sliding coupling
bar to be operated by appropriately constructed cams of inclines so that at
one time one wheel may be in effective operation, while the other runs idly
and at another time these actions are reversed.

I, JOSEPH MATTHEW SELLERS, of the Firm of W. Sellers and Sons, of Keighley,
in the County of York, Machine Makers, 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, that is to say:
It relates to means for transmitting rotary motion to the dollying mechanism
of domestic washing machines of the class wherein the said mechanism is mounted
upon so as to be carried by the lid or cover of the box or receptacle in which
the clothes to be washed are placed, and my said invention consists in construct-
ing and arranging said mechanism so that while rotary motion is trans-
mitted thereto for a certain period in one direction and for a like period in the
opposite direction, the dolly in the box or receptacle may act at any desired
position or height in said box or receptacle as the quantity or bulk of the clothes
may determine.
In order that my said invention may be readily understood, I have hereunto
appended sheets of drawings illustrative thereof, to which, by figures and letters,
reference is made in the following description.
Figs. 1 and 2 are elevation and plan respectively of a domestic washing machine
constructed in accordance with my invention.
Fig. 3 is a cross sectional elevation of parts shown by Fig. 1.
Figs. 4 and 5 are similar views to Figs. 1 and 2 respectively but illustrate a
modification of my invention.
Figs. 6, 7 and 8 are sectional elevation, end elevation and plan respectively,
of my improved coupling mechanism hereinafter described.
Figs. and 10 are elevation and plan respectively of another form of coupling
mechanism hereinafter referred to.
Figs. 11, 12, 13 and 14 are detail drawings hereinafter referred to.
Figs. 6 to 14 inclusive, are drawn to an enlarged scale.
Similar letters and figures of reference indicate similar parts throughout the
several views.
In carrying my invention into effect I form the shaft a which carries the
dolly a square (or other shape than circular) in cross section, so that it may
slide through the coupling piece 6 for securing it to one or other of its driving
wheels d (these latter being driven through the hand wheel e, shaft f and
toothed wheel in the ordinary manner) and yet at any position therein said
coupling piece 6 may transmit the motion desired to it. To enable me thus to
make use of, the square shaft a I construct the bearings h h for said shaft a,
which are mounted on the lid of the receptacles in which the clothes to be
washed are placed, to receive bushes m m with holes m², m³ for the shaft a to
pass through them of a shape corresponding with that of said shaft, by which
means when the shaft a rotates it carries the bushes m, m¹ with it to rotate in
their bearings h, h¹.
Instead of making use of the bushes m, m³, I may employ a circular shaft a³
(see Fig. 4) having the key-way a formed in it to receive the key b¹ formed on
the coupling piece b, this arrangement of parts being shown as applied to a
machine in which is used the old and well known style of coupling lever 63, this
latter being put into and out of gear alternately with the driving wheels c, d
by the incline parts k, causing said lever to be moved so that at one time
its upper end engages with the notch c¹ in the wheel c, in this manner the

page_text: dolly is rotated for a certain period in one direction, then by said lever
coming into contact with the incline k, its lower end will be caused to enter
a notch in the wheel d thus causing the dolly to be rotated in the opposite
direction, as will be understood, however I may use the herein before described
loose bushes m m and square shaft a in connection with this form of driving
mechanism, so also may I employ the round shaft a, in which is formed the
key-way a³, with my improved form of coupling bar hereinafter described.
The coupling barn above referred to is mounted to slide within the part b
which encircles the shaft a, and is put into and out of gear with the driving
wheels c and d by means of the pin or projection (which extends from said
shaft and slides within the slot o) coming into contact with the upper or under
surface of the incline part p, thereby being raised within the opening & formed
in the wheel c (see Figs. 13 and 14) or depressed within a similar opening in
the wheel d, thus reciprocating rotary motion will be imparted to the dolly a¹
as is desired. The coupling bar n is held in any requisite position vertically by
means of the spring q acting upon the incline na formed on said bar n.
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:
In domestic washing machines of the class described, driving mechanism and
parts in connection therewith, the same being constructed and arranged to operate
substantially as herein specified.
Dated this 15th day of November 1899.
