I, JAMES BATHGATE, 17 Dalmeny Street, Leith, Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to washing machines & consists in the improved construction
of same, being carried out as follows.
The spindle carrying the drum is driven by means of an elliptical pinion keyed
to same, gearing with an ordinary circular pinion set excentrically upon its spindle
to which the power is applied; running on the drum-spindle is a bush carrying a
disc at its inner end & also driven by an elliptical pinion the long axis of which is
placed at right angles to the long axis of elliptical pinion driving the drum spindle,
this second elliptical pinion gearing with the driving spindle by means of an
excentrically set circular pinion, thus a variable motion is imparted to the drum
and the disc; this disc carries a series of levers which are so arranged, that they
oscillate a set of pressers, extending from one side of the drum to the other, and
forming the enclosing surface of same these pressers are pivoted to the sides of the
drum at both ends & also to one another at their edges, may be made of corrugated
material & are for the purpose of imparting a pressing, rubbing or agitating
motion to the articles being washed, which are put into the enclosure formed by
the pressers & sides of drum through a door in one of the said pressers. The
sides of the drum may be fixed or held in position by stays & may be together with
the disc aforesaid enclosed in a suitable casing or tank for holding water.

I, JAMES BATHGATE 17 Dalmeny Street Leith, 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:-
This invention relates to washing machines & consists in the improved construction
of same, being carried out as follows.
The spindle carrying the drum is driven by means of an elliptical pinion keyed
to same gearing with an ordinary circular pinion set excentrically upon its spindle
to which the power is applied. Running on the drum spindle is a busch carrying
a disc at its inner end and is also driven by an elliptical pinion the long axis of
which is placed at right angles to the long axis of elliptical pinion driving the
drum spindle, this second elliptical pinion gearing with the driving spindle by means
of an excentrically set circular pinion. Thus a variable motion is imparted to the
drum and the disc. This disc carries a series of levers which are so arranged that
they oscillate a set of pressers extending from one side of the drum to the other
and forming the enclosing surface of same. These pressers are pivoted to the sides
of the drum at both ends and also to one another at their edges, may be made of

agitating motion to the articles being washed which are put into the encloseures
formed by the pressers & sides of drum through a door in one of the pressers. The
sides of the drum may be fixed or held in position by stays and may be together
with the disc aforesaid enclosed in a suitable casing or tank for holding water.
In order that my invention may be fully understood I now refer to the annexed
drawings in which:-
Figure 1. is a view showing my invention applied to a tank boiler or copper.
Figure 2. side view of same.
a and a are the two ends of the drum and to which the levers b and c which
operate the pressers d & d' are supported. The spindle e which causes the ends of
the drum to rotate has the elliptical wheel fattached to same which gears with
the circular wheel f¹ which is excentrically set upon the driving shaft g. The
elliptical wheel is secured to the loose sleeve i upon the spindle e & engages with
the circular excentrically set wheel ¹ said loose sleeve carrying the discj to which
the ends k of the levers bare pivotally connected. The clothes are passed into the
spaces formed between the pressers through an opening or aperture at or about o
in said pressers. It will be seen that owing to the differential motion between the
outer ends of the drum and the pressers that is the one gaining and losing in speed
alternately owing to the employment of the elliptical and eccentrically set wheels,
that the clothes will be subjected to a squeezing & rubbing motion, owing to the
movement or oscillation of the pressers. The pressers d are operated by the pivoted
levers & c which are operated by the gaining & losing in the rate of speed of
the spindle e and sleeve i through the medium of the elliptical wheels f & h and
eccentrically set wheels f & i carried by the driving shaft g.; the alternate
pressers are pivoted to the pressers d as shown at p and to the ends of the drum
at p', thus it will be seen that the pressers d' will move or oscillate in a corresponding
manner to the pressers d; the dotted lines indicate the alternate position of one
presser d & the adjacent alternate presser d'. The driving shaft g may be driven
by any suitable power. The drum and pressers rotate in the tank, boiler or copper
which contains the required fluid for washing purposes.

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 combined construction and arrangement of the various parts substantially
as described and illustrated herein.
2. In washing machines a series of pressers pivotally connected together and
operated by levers connected to a disc carried upon a loose sleeve running upon a
spindle carrying the ends of a drum between which the pressers work said loose
sleeve & spindle carrying elliptical wheels operated by eccentrically set wheels
carried upon a driving spindle and gearing with the elliptical wheels thus giving
a varying rate of speed to the loose sleeve and spindle aforesaid, an opening or door
in said pressers.
