I ELIZA JANE JARDINE of Dromore in the County of Down in Ireland
Spinster do hereby declare the nature of this invention to be as follows:-
My invention relates to machines employed in the cleansing of linen cambric and
other similar materials which are liable to damage by being caught between the rim
or bottom of the machine and the dolly.
In order to prevent such damage I employ a horizontal ring set and bolted into
a groove in the bottom of the machine and furnished with perpendicular pins and
springs which support a flanged or tongued hoop or rim equal in circumference to
the periphery of the dolly.
I provide the flange or tongue of the boop or rim with sockets into which the
pins pass so as to prevent the movement of the hoop or rim in a lateral direction.
The springs keep the flanged or tongued hoop or rim in contact with the rim of
the dolly so that there is not any interval between them for the materials being
cleansed to be caught in and damaged by.
I may, however, keep the flanged or tongued hoop or rim in position by other
means than perpendicular pins.

Improvements in Washing Machines.
I ELIZA JANE JARDINE of Dromore in the County of Down in Ireland
Spinster 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 :-
My invention relates to machines employed in the cleansing of linen, cambric
and other similar materials which are liable to damage by being caught between the
rim or bottom of the machine and the dolly and is specially applicable to machines
consisting of a circular tub or vessel with vertical ribs or projections on its inner
surface and of a dolly composed of a disc with an elongated boss or centre carrying
projecting ribs and caused to rotate in each direction alternately and reciprocally.
In order to prevent such damage as I have mentioned I employ a horizontal
stationary ring set into a groove in the bottom of the machine and furnished at
intervals with perpendicular pins and springs which stay or control and support a
flanged or tongued hoop or rim equal in circumference to the periphery of the
dolly.
I provide the flange or tongue of this hoop or rim with sockets into which the
perpendicular pins pass so as to prevent the movement of the hoop or rim with
the dolly in a lateral direction.
The springs keep the flanged or tongued rim in contact with the rim of the
dolly so that there is not any interval between them for the materials being cleaned
to be caught in and damaged by, while the elasticity of the supports of the
stationary hoop or rim allows it also to adjust itself to variations in the vertical
position of the dolly.

page_text: In constructing my improved machine for practical use I have made some
modifications in my arrangements which I prefer. According to these modifications,
instead of placing the dolly above the horizontal ring and flanged or tongued hoop
or rim, I enclose it within them and furnish it, on its upper surface, with a
horizontal projecting circular flange against the under surface of which the flanges
or tongues of the hoop or rim is pressed into close contact by means of the
supporting springs so as to form a close fitting joint between them."
This hoop or rim is provided on the under surface with cavities or sockets to
receive the perpendicular pins and springs which are fixed in a grooved or flanged
horizontal stationary ring attached to the bottom of the tub or vessel and enclosing
the flanged or tongued. hoop or rim. I may employ additional springs at intervals
independently of the perpendicular pins and the hoop or rim may be slotted,
or perforated between the pins and springs for the purpose of making it
And in order that my said invention may be more fully understood I shall now
proceed to refer to the figures and letters upon the several sheets of drawings
hereunto annexed the same letters of reference indicating the same or corresponding
parts of my improved washing machine throughout all the figures.
Fig. 1 is a plan of a circular washing machine with vertical ribs and a dolly
having an elongated boss or centre with projecting ribs and it shows the disc
provided with a horizontal projecting circular flange, the rim of the disc or base
being indicated by a dotted line on the flange. The positions of the perpendicular
pins and springs are indicated by small circles also on the flange.
Fig. 2 is a cross section of the same machine and dolly which shows the horizontal
projecting circular flange on the upper surface of the disc or base of the dolly, the
hoop or rim with its flanges or tongues in contact with the under surface of the
horizontal projecting circular flange and furnished with sockets to receive and
stayed or controlled and supported by perpendicular pins and springs fixed in a
grooved or flanged ring attached to the bottom of the tub or vessel and enclosing
the flanged or tongued hoop or rim and
Fig. 3 is an enlargement in section of the periphery of the dolly's disc or base,
the horizontal projecting circular flange, a cavity or socket in the hoop or rim and
the grooved or flanged ring attached to the bottom of the tub or vessel and
furnished with a pin and spring to stay or control and support the hoop or rim.

or flanged ring attached to the bottom of the tub or vessel, a; b is the disc or base
of the dolly and 6' the elongated boss or centre on its upper surface, with the
projecting ribs b², 6; 6 is the horizontal projecting circular flange on the disc or
base of the dolly b; c is the hoop or rim with its flanges or tongues, o' c¹, kept in
close contact with the under side of the horizontal projecting circular flange, 6, by
means of the springs, o³, and prevented from moving in a lateral direction by means
of the perpendicular pins, c, c, and c is one of the sockets into which the springs, o³,
and the perpendicular pins, c³, pass for the purposes above mentioned.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The use, in circular washing machines with a revolving or reciprocating
dolly, of a non-revolving hoop or rim arranged with flanges and sockets, stayed
and controlled by perpendicular pins and supported on springs substantially in the
manner and for the purposes hereinbefore described and shewn in the drawings
hereunto annexed.
2. The use, in circular washing machines with a revolving or reciprocating dolly,
of a grooved ring or a groove arranged with perpendicular pins and springs
substantially in the manner and for the purposes herein before described and shewn
in the drawinga hereunto annexed and

machine constructed and employed substantially in the manner and for the purposes
herein before described and illustrated by the drawings on the sheet hereunto
annexed.
