In Figure 1, I have illustrated a form of my
invention as applied to a two-tub washing and
extracting machine.
The machine illustrated
comprises a washer tub or casing l and an ex
tractor tub or casing 2. These elements of the
machine are carried on a suitable frame or base
member ,3, supported by legs 4 having casters 5,
provided for the purpose of facilitating the mov
ing of the machine. The washer tub is secured
to the frame member 3 by means of a number 55
of bolts 6 circumferentially spaced about the
bottom of the tub at points adjacen to the outer
edgeihereof. The extractor ca g 2 is secured
to the base 3 in a similar manner by means of
bolts ‘I. The extractor casing 2 is provided with
an apertured top-plate 8 which provides a clothes
chute as between the adjoining parts of the tub
I and casing 2. The plate 8 is ?tted snugly over
the top of the casing 2 and is secured to the tub
10 I by the bolts 9. Within the extractor casing
2 there is provided a rotatable container in hav
This clutch is of the friction cone type and it has
ing perforations II whereby adherent water may
be removed from fabric articles during the cen
through a slot 42 formed in the bushing 38.
The lower end of the bushing 38 is formed with
trifugal extracting operation.
a shoulder or collar 43.
An agitating device comprising a base-member
I2 of spherical contour and having vanes I3, is
provided for agitating the liquid contents of the
washer tub or casing I. The base-member I2
is closely ?tted over a hollow shield I4 of spherical
20 contour within which certain parts of the driving‘
mechanism for the agitating member are housed.
The agitating device is driven with a combined
gyratory and rotational movement. The driving
of the agitator is effected through a rotatable
agitator-driving shaft I5 to which is rigidly
amxed a bracket I6 carrying an angular crank
I1 which is in the form of a stub shaft ?xedly se
cured to the bracket I6.
The bracket I6 is preferably in the form of a
30 die casting and is cast about the shafts I5 and
I1 so that these three elements form an integral
unit. The base-member I2 is provided with a
central bearing portion I8 within which the shaft
I ‘I is rotatably journaled. The base-member I2
35 is secured in place on the shaft H by means of a
washer I9 and a screw 28, the screw engaging the
shaft I1 and the washer I9 overlapping and en
gaging the countersunk central portion of the
member 12.
A gear 2| is secured in threaded engagement
to the underside of the base-member I2 in align
ment with the axis of this member. The gear 2|
meshes with a ?xed or stationary internal gear
22 threadably secured to the bearing member 23
45 of the shaft I5. The outer edge of the internal
gear is extended in the form of an annular plate
24 and it carries at its outer edge the spherical
shield member I4. The bearing member 23 co
operates with the internal gear 22 and with suit
60 able gaskets 25 in sealing the opening provided in
a driving cone 31, the outer edge of which is
?xedly secured to the enlarged driving pulley 32
and the center of which is formed with a bearing
surface. The cone 3‘! is rotatably mounted on a
bushing 38. A driven conical clutch member 39,
faced with a suitable friction material 40, coop
erates with the driving clutch member 31 in con
trolling operation of the agitator shaft. The
driven clutch member 39 is ?xedly secured to the 10
shaft I5 by means of a set screw 4|, which passes
A cup-shaped member
44 having a ?anged rim is secured by any suitable
means such as the screw 45 to the lower end of
the shaft I 5.
A coil spring 46 is held in com
pression between the cup-shaped member 44 and
a washer 41 which abuts against the shoulder 43
of the bushing 38. The upper end of the bushing 20
38 abuts against a washer 48. The washer 48 in
turn is pressed against the lower end of a sleeve
49 and is held in such position by reason of the
force exerted by the spring 46.
A slanting slot 50 is formed in the sleeve 49 for
bearing member 23. An operating handle 52 is
?xed to the sleeve 49. When the operating
handle 52 is angularly shifted in one direction or
the other the inclined slot 50, working on the bolt 30
5| serves to raise or lower the sleeve member 49
and in doing so it axially shifts the bushing 38
and the driving clutch member 31, thus connect
ing or disconnecting the clutch members 31 and
39 with each other as the case may be.
This ar
rangement provides a simple and inexpensive
form of clutch device.
Suitable packing means 54 are provided in the
centrally enlarged lower portion 53 of the bearing
member \23. The packing material 54 carried at 40
this point is pressed in sealing relation about the
shaft I5 by means of a slidably‘r?tted gland 55 and
a spring 56, the latter being pressed against the
gland by means of an apertured nut 5‘! thread
edly engaging the lowermost end of the bearing
member 23.
In Figure 3 the clutch is shown in its disengaged
position and in Figure 5 the clutch is shown in its
engaged or driving position. In such positions
of the clutch and the sleeve 49, the stud 5| is

An electric motor 26 is provided to drive the
washing and extracting mechanism. A belt 21
65 provides a direct driving connection between the
motor and the extractor container ID, the pump
28 and the adjustable idler pulley 29. The idler
pulley carries a small pulley 30 for driving a sec
ond belt‘ 3|, which in turn serves to drive an en
60 larged pulley 32 for driving the washing mech
The washing and extracting mechanisms are
provided with suitable clutches whereby these
parts of the machine may be connected or dis
65 connected selectively in driving relation to the
electric motor. The pump 28 is continuously
driven, having at its inlet side an open communi
cating connection 33 with the extractor casing 2
and a valve-controlled communicating connec
70 tion 34 with the washer tub. The outlet side of
the pump is connected in communicating rela
tion with one end of a hose 35 which terminates
at its other end in a swiveled gooseneck 36.
The washing mechanism is controlled by means

Due to the fact that the internal gear 22 is larger
than the gear 2|, a rotational movement of

plate member 61 is provided with an apertured
up-turned portion 1| through which an adjust
ging rod 12 extends.
With the parts as shown, the base-member I2
is driven with a gyratory motion in one direction
10 about the axis of the shaft I5 and with a rota
tional motion in a reverse dire?mv about the
axis of the anguliiacrank H. Due to the com
pound motion imparted to this member the blades

28 is provided with a suitable control valve hav
ing an operating handle 60 for connecting and
disconnecting the pump to the washer tub. As
previously stated the pump is in continuous com
munication with the extractor tub 2 and the out
50 let side of the pump is in constant communica
tion with the hose 35.
The gooseneck 36 of the hose 35 is arranged for
reception in either of the openings 6| or 62
formed in a recess in the top of the extractor
Cl CA top plate 8.
The opening 6| communicates with
a drain hose 63, whereas the opening 62 com
municates with a side opening 64 formed in the
upper part of the wall of the washer tub. By this
simple expedient the water drained from either
the washer tub or the extractor tub can bedi
rected to a, suitable drain or returned to the
washer tub. This arrangement provides a very
convenient method of handling waste water from
the machine or for returning usable soapy water
from the extractor casing to the washer tub and
it at the same time prevents spilling and splash
ing water about the ?oor in the room where the
machine is used as the hose 63 empties into a
suitable drain or receptacle.
The idler pulley 29 is slidably mounted upon a
plate 65 and is secured thereto by means of a
lower and an upper'plate 66 and 61 secured to
gether by means of a -rivet 68 which is slidably
" ?tted in a. slot 69 formed in the plate 65. The
75 plate 66 has secured to it a stub shaft 10, which
The control lever 52 is shifted to the “on” posi 45
tion after the motor 26 has been started and
after a few minutes of agitation the operation
of the agitator is stopped, and the clothes are
transferred to the extractor casing Ill. The ex
tractor control lever 59 is then moved to the “on”
position and in a short time the centrifuge will
have extracted most of the water from the clothes
whereupon the centrifuge is stopped and the
clothes removed therefrom.
The clothes are next rinsed either by adding 55
clean water to the extractor while stationary or
rotating or by transferring them to a tub full of
rinsing water after which operation the clothes
are returned to the extractor for the ?nal drying
operation. During the initial extracting opera 60
tion the soapy w ter can be returned to the tub
I by connecting he gooseneck 36 to the hole 62
and during the second extracting operation the
rinse water can be conveyed to a drain by con
necting the gooseneck to the hole 6i. When the 65
washing is ?nished the valve member 68 is shifted
to open valve position and contents of the tub I
are pumped to a drain.
Furthermore it is to be understood that the
particular forms of apparatus shown and de-» 70
scribed, and the particular procedure set forth are
presented for purposes of explanation and that
various modi?cations of said apparatus and pro
cedure can be made without departing from my
