We, JOHN SHANKS, of Tubal Works, Barrhead, in the County of Renfrew, North
Britain, Sanitary Engineer, and JOHN MACLEAN, of 42 Dixon Road, Crosshill, in the
County of Glasgow, North Britain, Engineer, do hereby declare the nature of this
Invention to be as follows. that is to say :-
Our said Invention relates to washing machines of the kind in which within an
external casing there is a drum or cylindrical shell arranged to rotate upon a
horizontal axis, the inside of the drum being provided with bars or other
projections to act on the articles being washed. In such machines it is usual to
cause the drum to reverse the direction of its rotation at about every second
turn, or it might be at any other suitable period.
Hitherto somewhat complicated gearing has been applied for moving the drum
in the manner indicated; but by our Invention we employ improved and very

journal of the drum we fix a pinion and arrange in gear with it a toothed sector
of a size suitable for the extent of rotation to be imparted between the.
reversals; and the toothed sector is made to reciprocate angularly by a rod
connected to a crank on a rotating shaft driven by means of a belt and pulley
or otherwise. Or the toothed sector may be connected to and acted on directly
by the piston rod of a steam cylinder the distribution valve of which is worked
by tumbler, tripping, or other suitable mechanism.

Improvements in Washing Machines,
We, JOHN SHANKS, of Tubal Works, Barrhead, in the County of Renfrew, North
Britain, Sanitary Engineer, and JOHN MACLEAN, 42, Dixon Road, Crosshill, in the
County of Glasgow, North Britain, Engineer, 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 :-
Our said Invention relates to washing machines of the kind in which within an
external casing there is a drum or cylindrical shell arranged to rotate upon a
horizontal axis, the inside of the drum being provided with bars or other projections
In such machines it is usual to cause the drum
to act on the articles being washed.
to reverse the direction of its rotation at about every second turn, or it might be at
any other suitable period,

page_text: Hitherto somewhat complicated gearing has been applied for moving the drum in
the manner indicated, but by our Invention we employ improved and very simple and
satisfactorily working mechanism for the purpose. On the shaft or journal of the
drum we fix a pinion and arrange in gear with it a toothed sector made to reciprocate
angularly by a rod connected to a crank on a rotating shaft driven by means of a belt 5
and pulley or otherwise. Or the toothed sector may be connected to and acted on
directly by the piston rod of a steam cylinder the distribution valve of which is worked
by tumbler, tripping, or other suitable mechanism.
And in order that our said. Invention and the manner of performing the same may
be properly understood we hereunto append a sheet of explanatory drawings to be 1
hereinafter referred to and showing one modification of our improvements.
Figure, 1, on the accompanying sheet of drawings is a side elevation and Figure, 2,
an end elevation showing a part of one end of a washing machine sufficient to
illustrate the application of one modification of our improvements.
}.
As shown on the drawings the shaft or journal, A, of the drum (not shown) passes_1
through the external casing, B, and its outer end is carried in bearings in an end
standard, C. On the shaft or journal, A, we fix a pinion, D, and, arrange in gear with.
it a toothed sector, E, of a size suitable for the extent of rotation to be imparted
between the reversals. The toothed sector, E, is on a journal, F, the outer end of
which has on it a lever, G, jointed to a rod, H, connected to a crank pin, J, on the side 2
of a pulley, K, on a rotating shaft, L, the pulley being driven by means of a belt, M.
The rotation of the pulley, K, transmits motion through the rod, H, and lever, G, to
the toothed sector, E, so as to make it reciprocate angularly and thus impart through
the pinion, D, the desired rotation to the drum between each reversal.
Having now particularly described and ascertained the nature of our said 2
Invention and in what manner the same is to be performed, we declare that what we
claim is:-
In washing machines of the kind herein before referred to fixing on the shaft or
journal of the drum, a pinion and arranging in gear with it a toothed sector inade to
reciprocate angularly by a rod connected to a crank on a rotating shaft; or by the 3
piston rod of a steam cylinder, substantially as and for the purposes herein before
described.
