BENJAMIN COOPER REVETT and CHARLES THOMAS POWERS, both of Sheffield, in
the West Riding of the County of York. "IMPROVEMENTS IN MECHANISM TO
ACTUATE THE DASHERS OF WASHING AND MIXING MACHINES AND CHURNS."
These improvements relate to the construction of the mechanical powers employed
to actuate the dashers of washing and mixing machines and churns, and consists in
actuating the pinion fixed on the shaft of the dasher by two segments of wheels, or
by two wheels having teeth on a part only of their circumference or working face,
the said wheels being fixed on a shaft rotating continuously in one direction and
placed at right angles to the said dasher shaft, or otherwise so placed as that the
said wheels will gear into the said pinion and so actuate it, and further consists in
actuating the said dashers by one segment of a wheel, or wheel having teeth on a
part only of its circumference fixed on a shaft rotating in one direction continuously,
and gearing alternately into two pinions fixed on the dasher shaft, one placed above
the other, and so rotating the said dasher shaft.
The wheel or segment of a wheel, or the wheels or segments of wheels, will be so
constructed and fixed as that although they revolve continuously in one direction
they will so gear into the said pinions or pinion alternately as to cause the said
pinions or pinion and the dasher to which it or they are fixed to move round first
in one direction and then in the reverse direction.
The said wheel or wheels, segment of a wheel or segments of wheels, and the
dasher pinions or pinion can be so constructed and arranged as to cause the dasher
to move part of a revolution and back again, or to move one revolution and back
again, or to make more than one revolution in one direction and the same in
the opposite direction.
The shaft carrying the wheel or segment of a wheel, wheels or segments of wheels,
can be constructed of wrought iron, steel or any other suitable material, and the
wheel or wheels, segment of a wheel or segments of wheels, and the dasher pinion
can be constructed of cast iron, brass or any other metal or metallic alloy, and the

page_text: shaft can be placed horizontally in the machine to which these improvements are
applied, and the shaft of the dasher placed vertically, or the shaft carrying the
wheel or wheels and the dasher shaft can be otherwise arranged in relation to one
another, but so arranged and so constructed as that the wheel, wheels or segment
of a wheel or segments of wheels shall at the proper time gear into the pinion or
pinions, and although revolving in one direction only shall rotate the said pinion
or pinions completely or in part, first in one direction and then in the opposite
direction.
The dashers actuated in the manner above specified can be applied alike to
machines for washing clothes or textile fabrics generally, to machines for mixing
paints or other semi-fluids or fluids, or any substances requiring to be mixed, or to
churns for making butter.
