10 Claims. (01. 68-—15)
Fig. 7 is a section of the ?exible coupling on
This invention relates to domestic washing
machines of the type in which the water con
tained in a tank or the like, in which the clothes 7
are being washed, is agitated either by hand or
5 mechanically. In the usual arrangements, the
machine comprises a tank or container, with or
without various rubbing abutments or corruga
tions on the sides, a central vertical spindle be
ing adapted to carry an agitator of suitable form
10 which is immersed in the water and amongst
the clothes.
These known arrangements possess certain
drawbacks, particularly as regards the diiliculty
of providing proper bearings for the spindle,
l5 straining of the clothes by lubricant, rust or so
called verdigris, and the interference of the un
derneath operating mechanism with devices for
heating by gas or the like.
'
It is one object of the present invention to
avoid those disadvantages and at the same time
20 to provide a simple, e?icient and reliable washing
machine intended for domestic use.
Another
object is to provide a turntable device between
the tank and its support which device whilst
allowing the tank to be freely oscillated does not
25
interfere with the heating of the tank from un
derneath.
I employ a tank or container arranged for
oscillation on a vertical axis and provided with
the motor shaft.
Fig. 8 is an elevation of the reduction gearbox
in vertical section on the axes of the shafts.
" _ Fig. 9 is a longitudinal section and Fig. 10 a 5
transverse section of the reversing gearbox for
driving the wringer.
Fig. 11 is a plan of a modi?ed buffer device
for the driving of the oscillating tank.
‘
Fig. 12 is a vertical section on the line |2—-|2 10
of Fig. 11, on an enlarged scale.
Fig. 13 is a fragmentary view of a detail of
construction showing the form of certain slots.
As shown in Figs. 1 and 2, the washing ma
chine is constructed in the form of a cabinet. 16
made of pressed steel or the like, preferably ?n
ished in vitreous enamel, the cabinet being of
rectangular shape, with four ?at sides or panels
In, four legs “fitted with moulded rubber feet
l2, and a top l3; the sides, legs and top are se- 20
cured together by concealed bolts l4, and the
legs are reinforced by angular metal straps I5
for supporting the heavy parts in the interior of
the cabinet.
Carried approximately half-way down the 25
cabinet, and secured to the upper ends of the
straps I5, is a‘press‘ed steel base-plate l6 form
ing a central bracing for the body of the cabinet
and having a large circular opening of which the
30 agitator paddles or the like moving with the
tank, the tank being mounted on an annular
bearing track or turn-table with an open center,
periphery is shaped to form a cup or ball-race I1, 30
35 the tank and in the open center of the bearing
a turn-table. The inner periphery of the ro- 35
tatable plate I9 is ?tted with a number of safety
catches 2| adapted to engage under the station
ary ball race I‘! to prevent the two plates from
?tted with caged balls l8. Upon this ball bearing
there is rotatably mounted an annular pressed
and a gas burner or other means for heatingv steel plate /,I9 forming a complementary ball race
the water being placed beneath the bottom of or cone 20,; so that the two plates l6, lfcbnstitute
track or turn-table.
Preferably the washing machine is provided
with means for power operation, a wringer or
the like accommodated upon the washing ma
40 chine being also driven by power from the same
source when desired.
The invention is hereafter more fully de
scribed with reference to the accompanying
drawings, in which:

Fig. 1 is a part sectional elevation of the ma
chine in the preferred embodiment.
Fig. 2 is a part side elevation showing the top
cover in use as a rinsing bath.
Figs. 3 and 4 are details of a stand seen in
50 Fig. 2.
Fig. 5 shows the stand folded ?at and hanging
against the rear panel of the machine.
Fig. 6 is a detail in section on the line 6-6 of

separating during normal operation. The upper
flat portion 22 of the plate l9 has blocks 23 spaced 40
at intervals round its circumference and secured
by bolts 24, the rim of the plate being ?anged
upwards at 25 outside these blocks, upon which
there rests an open-topped cylindrical tank 26,
constructed of sheet metal; the peripheral ?ange 45
25 of the plate 19 forms a guide to facilitate the
centering of the tank thereon and to hold it in
position during operation, but allowing the tank
to be lifted completely out for cleaning, or for use
as a separate boiler, or for other purposes. Addi- 50
tional guide arms 21 may also be provided as
shown, these arms being engaged under the
blocks 23 and secured by the same bolts 24.
The open top of the tank 26 has a ?anged rim
Z5 doubled, back inwards to provide a bead 29 56

tank is provided internally with a plurality of
shaft 58 of the gearbox 58 carries at its lower
vertical paddles or vanes 33, which as shown are
integral with the arms of a spider 34 resting on
end an external crank 58 driving a connecting
rod .68 which transmits oscillatory motion to. the
rotatable plate I8 supporting the tank; bu?er I0
springs are preferably arranged to cushion the
shocks at the reversal of motion, this being done
for example, as shown in Fig. 1, by providing a
bridge 6| between two points on the inner pe
10 the bottom- of the tank. The clothes placed in
the tank for washing are therefore held away
from the bottom of the tank by the~ paddles
mounted on or near the bottom, and the clothes
may be boiled while the agitation is taking place.
15 The spider 34 has its arms forked at their extrem
ities to engage with radial driving lugs 35 of tri
angular shape, having integral ?anges riveted or
soldered to the walls of the tank. The spider 34
can thus be readily lifted out of place, leaving
20 a plain tank which can be used as an ordinary
boiler when so desired, the spider being subse
quently re?tted by engaging its arms with the
driving lugs 35.
If desired, the detachable lid 38 may be pro~
K1 CH vided with paddles or stirrers as indicated at
36, consisting for example of non-rusting metal
tubes closed‘ at their lower ends; the lid 38 is
arranged to ?t su?iciently tightly in the bead
29 to prevent slip during the oscillation.

Beneath the tank and projecting into the cen
tral opening of the annular plate I8, there is
mounted a gas burner 38, fed by a connection at
381, this burner being supported by a cross-bar
39 having its ends turned up and cranked out
wards for attachment to the base-plate l6 as
indicated in dotted lines at 48. A shallow tray‘
4| is provided beneath the burner in order to
collect condensation water, the edges of. this
tray having a tight fit upon the turned-up ends
of the cross bar 39. The outer end of the burner
tube 42 is also supported by a stay 43 secured to
the periphery 44 of the base-plate I6, and is
provided with the usual adjusting sleeve 45 for
regulating the air supply to the burner; an oval
opening 48 in the side panel I8 through which
the gas-connection 381 extends, allows this sleeve
to be adjusted, a similar opening or openings 41
being provided in one or more of the other pan
riphery of the plate I9, and mounting a vertical '
pin 82 thereon, the connecting rod 68 being at
tached to this pin 62 by a stirrup 83, with springs
64 inserted between the stirrup and the nuts 65
on the connecting rod.
The shaft 58 is con
trolled axially by a rod 66 extending up through 20
a guide 6'! in the top I3 of the cabinet and pro
vided with a knob 68 by means of which the
shaft can be lifted so as to disengage the drive,
as hereafter explained, the shaft being then ‘re
tained in this disengaged position by turning 25
the knob 68 so that a cross-pin 68 rests on the
upper edge of the guide'G‘I; in order to re-en
gage the drive, the knob 684 is turned to drop the .
pin 69 into its notch ‘I8 in guide 61.
A second low-speed driven shaft ‘II extends up 30
from the gearbox 58, in axial alignment with
the motor shaft 48, in order to drive an ac
cessory such as a wringer ‘I2, which is mounted
above the top l3 of the cabinet; power is con
veyed to the wringer through a gearbox ‘I3 pro
vidingfor reversal and interruption of the drive.
and also allowing the wringer to be swung about
a vertical axis in line with the shaft ‘II, the
wringer being supported from the gearboxv ‘I3
as hereafter described.
~
In the position shown in Figs. 1 and 2, the
wringer ‘I2 is adapted to operate on clothes lift
ed out of the tank 26, such clothes passing
through the rollers ‘I4 and being received at the
back of the machine; as shown in Fig. 2, a rins
ing bath ‘I5 is provided into which the clothes
are run, this bath being supported on a col
els I8 to allow of lighting and viewing the gas
lapsible stand. The latter comprises two legs
or uprights ‘I6 each having a' bearer ‘I‘I hinged

blocks 23 and upwards around the tank 26,
emerging through the opening in the top I3 of
the cabinet beneath the rim 28 of the tank.
The power unit comprises an electric motor
48 with vertical shaft 48 ?exibly coupled to a
gearbox 58, which is mounted upon the base plate
I6 over a second circular opening in the latter;
one of the rear legs II, with its reinforcing strap
I5, forms in efl’ect a bed-plate for the power
unit, the motor 48 being bolted to this leg over
the lower end of the strap, while the base
plate I_ 6 is bolted to all the four legs at the upper
ends of the respective straps I5. As seen in
Fig. 6, the motor 48 has a ?at face 5I secured to
65 a bracket 52 shaped to engage the angularrstrap
I5, 0. single bolt 53 holding the bracket 52 in
place; thusthe motor can easily be removed for
inspection or repair, and a motor of any par
ticular type or voltage can be ?tted to suit the
available supply of current. The motor shaft
49 has its upper end formed with two' opposite
?at faces 54 whereby it has a readily detach
able driving engagement with a moulded rubber
coupling 55 which is similarly engaged with the
primary shaft 56 of the gearbox 58; the center
40
tween the uprights and a wooden block 88 at
tached thereto above the bar ‘I8; a second spacer
bar ‘I9 is fitted between the lower ends of the
uprights, the bath ‘I5 being mounted on the
bearers 11, between the blocks 88 and the back
of the cabinet. When in use, the stand is con
nected to the cabinet by hooking the free ends
of the bearers ‘I.‘I upon pegs 8| projecting from
the rear panel I8, the bearers being provided with
shoes 82 (see Figs. 3 and 4) suitably notched at 60
83 for connectionto the pegs; when the stand
is not required, the bearers are detached from
the pegs 8| and folded down against the up
rights ‘I6, the folded stand being then turned
round and mounted ?at against the rear panel 65
I8 (as shown in Fig. 5) by hooking on to the
pegs 8| and also on to similar pegs 84 at a lower
level, for which purpose keyhole slots 85 (as
shown in Fig. 13) are formed in the uprights.
The bath ‘I5 may be arranged to form a cover 70
for the cabinet when not in use, the bath being
then inverted as indicated at ‘I51 in Fig. 2; the
wringer ‘I2 is adapted to fold down ?at on the
top of the cabinet as indicated at ‘I21 in Fig. 2,
so as to ?t inside the inverted bath.
