AN IMPROVED AGITATOR APPLICABLE TO A CHURN OR WASHING MACHINE
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I JOSEPH STENNER, Engineer, of Fore Street, Tiverton, in the County of Devon,
do hereby declaro the nature of my invention for AN IMPROVED AGITATOR
APPLICABLE TO A CHURN OR WASHING MACHINE, to be as follows:-
A special box or receptacle is suspended in the ordinary way upon two axles
which revolve upon bearings placed upon a frame or support, and is caused to
revolve by a band and pulley or cranked handle or some other method, extra speed
being given by multiplying wheels when desired.
The aforesaid box or receptacle which is claimed as the novel part of the
Invention, in combination as above-stated, being of the shape shewn in the
accompanying sketch, the effect of which is that when the box revolves, a constant
rolling concussion is caused whereby clothes are effectually cleansed, and when
used as a churn butter is produced quicker and in larger quantity than by the
ordinary methods.

do hereby declare the nature of my invention for AN IMPROVED AGITATOR
APPLICABLE TO A CHURN, OR WASHING MACHINE and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:―
In the ordinary Washing Machines, and Churns, the necessary agitation of the
contents is usually obtained by inserting ribs or bars projecting from the interior
surface, or else by employing a distinct rotating Apparatus in the centre, or in
other elaborate ways. Such Machines are open to many objections-They are
complicated, expensive, difficult to clean, and require much labour to produce the
required results. In this Agitator the rapid motion and admixture of the contents
is obtained from the configuration of the body or container in the easiest, most
simple, and least costly manner. While the machine is exceedingly easy to keep
clean, as it can be made, if preferred, with a comparatively smooth internal surface,
and can dispense with ribs, bars, or divisions for most purposes. The box or body
of the Machine rotates on two horizontal bearings fixed to a framed support in the
usual way, and is therefore easy to work by hand or power. The peculiarity and
novelty lies in internal shape of the body or box, as shewn in the accompanying
drawings.
Figure 1-represents a view in section.
Figure 2-a side elevation.
Taken in section the body resembles a square or parallelogram which has two of
its opposite Angles cut off, so as to form a six sided enclosure having by preference
2 right Angles and 4 obtuse Angles. The effect is, that when the Machine is rotated
the contents while revolving are thrown forcibly from one side to the other, and a
powerful shaking or mixing is caused with the result that a constant and most
vigorous agitation is created. This agitation rapidly churns milk or cream into
butter, cleans soiled clothes, or mixes materials requiring admixture.
Having now described and particularly ascertained the nature of my said
invention and the mode in which it may be used or employed, I would observe in
conclusion that I do not confine myself to the exact configuration herein described,
but what I claim and desire to protect in the aforesaid invention is;
1-An Agitator, or mixer, having a body, or container, similar in principle to the
one herein indicated, and capable of imparting a reciprocating lateral motion to
the contents when revolving, substantially in the manner and for the purpose
described.
2-The Agitator, or Mixer having the internal configuration similar to, or
resembling that shewn in the accompanying drawings substantially in the manner
and for the purpose described.
Dated this Seventeenth day of December 1884.
