Reference is now had‘ to ‘the drawings and
_more particularly to Figures 1 and 2 thereof
wherein a washing machine generally indicated
by the reference numeral I0 is provided with a
wringer i I supported by a housing l2. The hous
ing I2 is in turn mounted on a drive housing l3
which extends downwardly of one side _of the
washing machine i0.
7
The housing l3 encloses a drive shaft 14 con
nected in any suitable manner with the mecha-'
nism utilized to operate the washing machine. 25
The upper end of the housing I3 is of sufficient .
thickness to accommodate sockets l5 which may ,
be arranged in a circle 90 degrees apart. A fur
ther socket I6‘ is located midway‘ between“ one
pair of sockets I5. These sockets. constitute a
part of the indexing mechanism hereinafter fully
described.
The housing 12 which encloses the wringer
driving and indexing mechanisms is formed with
a downwardly directed annular collar 20 adapted
to ?t upon the upper end of the housing l3.
Within the housing adjacent the collar 20 is a
web portion 21 providing a bearing 22 in which
ashaft 24 is mounted. The lower end of the
shaft 24 is connected with drive shaft I4. The
upper'end of the shaft 24 is ?tted with a pinion
gear 25 which projects upwardly into a compart
ment 26 of the housing l2. Projecting inwardly
from the end wall 21 of the housing is a boss 29 '
in which an opening 30 is made. The boss 29 is
opposite the open end of the housing and is

is made connecting the interior with the exterior
of the housing. Adjacent to and formed integral

which have threaded engagement with the wall
36 and serve to secure the plate in place. Cen
trally of the plate 39 is an opening 44 which con
10 stitutes a further bearing for shaft 3|. The free
end of shaft 3| is ?tted with a drive pin 45 with
which a sleeve 46 is engaged. The other end of
the sleeve 46 is slotted to engage a further pin

15 makes possible convenient assembly and disas
sembly of wringer and drive head.
,
and projecting upwardly to a point slightly be
neath one of the ledges 10, is formed with an en
larged portion 80 in which a cylindrical opening
8| is made. This opening commences at the lower 10
end of the collar 20 and projects to adjacent the
upper end of the portion ‘89, continuing there
through in a reduced diametered opening 82.
Mounted in the opening 8| is an indexing pin 84.
The lower end of this pin projects beneath the
. collar 20 and is adaptedto register with one of
That portion of the shaft 3| lying within the
compartment 26 is ?tted with pins 49. -A twin
gear 5| is mounted on the shaft 3| and includes‘
20 opposed. sets of teeth 52, either set of which is
engageable with the pinion gear 25. The opening
in the gear 5| is formed with oppositely disposed
key ways 53 into which the ends of pins 49 pro‘
ameter to form an extension 85 which projects.
through the opening 82. Between the upper end
of the opening 8| and the upper end of pin 84 is
a spring 81, which normally exerts a pressure
on pin v84 to move it downwardly out of opening
' ject. It is to be understood that the diameter of
25 the gear 5| is slightly less than the diameter of‘
ditions\ hereinafter fully described,v projectible
the opening 31, thus permitting inserting this
gear through said opening during assembly.
Located on top of the housing l2 >is a revers
ing lever 55. Within the opening 35 of the por
30 tion 34 is a shaft 56 from which projects a pin
51. The lever 55 is mounted upon and secured to
this pin. Midway‘of the shaft 56 is an annular
groove 59 in which at predetermined positions,
depressions 60 are made. An opening 6| .is made
35 in portion 34. In this opening is a bullet nosed
pin 62 which is normally engaged with they an
nular groove 59 and one of the depressions 66,
due to contact with a spring 64. Pressure of the
spring 64 upon the pin 62 is varied by adjust- ~
40 ment of a screw 65 which. is threaded into the
‘outer end of the opening 6|. In this connection it’
is to be understood that shaft 56 may be rotated
byrotation of lever 55 and the bullet nosed pin 62 ,
will move out of a depression 60, but the enlarged
45 portion thereof will not move out of the groove
the sockets |5 or I6 formed in the housing |3._
The upper end of the pin 84 is of reduced di

0f shifter block 1| or into the recess 15.
I
On that portion of the housing l2, heretofore
designated as, collar 20, is, an indexing lever 90.
This lever is mounted on a shaft 9| that extends 30
through collar 20 into portion 80, through a suit
able opening 93. The shaft 9| is formed with
a pair of slots 95 and 96. .The base wall of each
slot is shown to be at a 45 degree angle to the
center line of the’lever 99. A stop pin.9'| is 35
mounted in the collar 20 of the housing and pro
jects through slot 95. Referring to Figure 10, it
will be noted that the pin 91 limits the indexing
lever 9ll-to a 90 degree turn, an edge of the slot
striking the pin in either dotted or solid line posi
tion of this ?gure. Slot 96 is of su?icient width
to receive pin 84. The edge 99 of the base wall
of this slot serves as a shoulder which engages
the upper wall I00 of a slot |0| formed trans
verely of pin 84. Rotation of the lever 90 from 45

Conversely, when the lever 55 is moved in the op
posite direction 90 degrees, roller 68 moves to
‘the right.‘
Reference is now had more particularly to fur~
ther interior structure of housing |2 (see Fig. 3),
Between the top‘ wall 33 and web portion 2| of
the housing and projecting inwardly. from each
side wall 69 thereof is a ledge or shoulder 10.

sockets | 5 or I6 in the housing l3, thus allow
ing housing I2 and wringer -||ito swivel about '
shaft M to any desired position. Generally
speaking, there are ?ve wringer positions, .one in
which the wringer is-centeredover the top of the
washing machine. ‘This position is obtained by
'locating the indexing pin 84 in socket 16. The
other four sockets facilitate setting the .wringer
