22 Claims. ' (Cl. 141-9)
This invention relates to washing machines.
One of the principal objects of the invention is
the provision of a washing machine of simple and
compact construction, in which the articles to be
5 washed may be readily inserted within and with
drawn from the machine.
Another object of the invention is the provision
of a washing machine having a casing, and a
movable cover member which is adapted to ef
iectlvely retain the washing ?uid within the eas
‘ ing during operation, and is adapted to be read
11y moved to an open position substantially within
the horizontal con?nes of the casing to permit
access thereto.
-
Another object of the invention is the provision
of a washing machine of this character having
simple and effective means for supporting racks
15
_ or other articles within the casing while permit
{ ting the cover to be moved within the casing to
20 positions beneath the rack supporting means.
Another object of the invention is to provide a
washing machine of this character having a
pivoted cover adapted to be readily rocked to posi
tions permitting access to either of opposite sides
.25
of the casing.
‘
Other objects and advantages of the invention
will be apparent from the following description,
face is located on the level with the upper edge
of the tank. Above the tank is supported an
open-bottom casing providing a chamber in which
the articles to be acted upon by this washing
mechanism are placed. To permit access to the 5
washing chamber, this casing is so supported that
it maybe tilted to bring one of its edges well
above the top of the tank, while, at the same
time, the opposite edge of the casing moves down
wardly into the tank so that the center of gravity
of the whole casing is only slightly raised. It is,
therefore, possible to tilt the casing with ‘little
e?ort, and no counter-balancing means are re
quired.
To permit one edge of the casing to move down
into the tank, I mount the support for the articles
to be washed in the tank in such manner. that it
has a long overhanging end extending towards
one edge of the tank under which an edge of the
casing may moved. I also select a washing mech
anism which may be supported near the middle
of the, tank, and which is provided with over
hanging portions under which the edge of the
casing may be moved. A suitable washing mech
anism of this class is the type usually known as 25
a rotary wash arm.
The drawings, in which like characters of refer
the accompanying drawings and the appended _ ence designate like parts throughout the several
claims.

A washing machine of approved construction
embodying the invention has an open~top tank
containing washing mechanism and a support for
the articles to be washed whose supporting sur
views thereof, illustrate in Figs. 1, 2 and 3 a wash
ing machine of this character having an open top
tank structure In suitably supported upon legs I I
and having a. movable casing or cover member I!
which serves as a closure for the open top tank
“I and, when in closed position, cooperates there
with to provide an enclosed washing compart 35
ment.‘ Rack supporting tracks I l are provided
within the tank, preferably at about the plane of
the top edge ii, for the reception of trays or racks
or similar containers for articles to be‘ washed.
Suitable washing heads are provided which are
adapted to spray ?uid jets upon the articles to be
washed and, as shown, include a rotary wash
arm 20 and rinse jets, one of which is shown at
2|. The rotary wash arm consists of a hollow
member provided with radial arms having nozzles,
some or all of which may be inclined so as to
cause rotation of the wash arm by the reaction
force of water discharged from the nozzles.
The tank I0 comprises vertically extending end
walls 22 and side walls 22', and an inclined bot- 50
tom wall 23 so shaped as to direct the liquid con
tents of the tank into a sump 24 which may be
formed as an integral part of the tank II. At the
junction of the sump 24 and tank I0 9. suitable
supporting ledge 25 is provided for the reception 55
2
2,128,008
ofva removable strainer 26 having a perforate
bottom member 21 for the collection of solid ma
45 from the tank structure Ill. As shown, the
track structure ll comprises rack supporting rails
terial dislodged during the washing operation. A
suitable drain, such as the threaded outlet 23, is
having horizontally extending portions 5| for the
provided to which a pipe connection may be at
tached for draining away the washing or rinsing
liquid. As shown, a stand pipe 30 is provided at
support of the racks or trays and upstanding por
tions 52 for the guidance of the racks. Suitable
supporting means are provided for the track
the outlet 28 so that a proper level of washing
liquid may be maintained in the sump 24 during
structure and are shown as vertically extending
arms or uprights 54 suitably attached to the track
members 50, as by means of rivets 55, and sup 10
10 washing operation. The stand pipe 80 is provided
with a tapered end 3| snugly received within a
tapered socket formed in the bottom wall of a
sump 24 immediately above the threaded portion
28 for the ready attachment and detachment of
15 pipe 30 and to provide a watertight joint to pre
vent the unintentional escape of washing liquid.
The stand pipe 3|) is provided at its upper end
with an opening or over?ow outlet through which
water, grease, scum, and the like, may pass upon
50 which are preferably of angular cross section
ported at their opposite ends 58 within projections
51 which are preferably formed integrally within
the tank structure Ill. The projections 51 are
preferably of socket like form within which the
portions 56 may be securely held for the support 15
of the track structure I‘, and from which they
may be readily withdrawn when it is desired to
remove the structure ll from the machine, as for
the purpose of cleaning it. The vertical supports
54, which are attached to the track structure near 20
20 exceeding the predetermined desired level within
the sump 24.‘ The pipe 30 is formed with a baille
the middle of its sides. are offset, as shown more
32 spaced above the over?ow outlet and providing
a handle for the pipe.
A circulating pump 33 having suitable driving
25 means, such as the motor 34, is provided for the
circulation of washing liquid and actuation of the
clearly in Fig. 3, from the side walls of the tank a
su?icient distance to permit the sides of the tilt
ing casing to enter between them and the side
walls of the tank. At the same time, these sup 25
ports 54 are near enough the sides of the tank to
wash arm 20. As shown, one side of the tank
structure ill opposite sump 2i is left open, and the
motor 34 and pump 33 are mounted within this
30 space so that access is readily had‘thereto, the
motor being supported upon a shelf 35 carried by
the tank “I and legs H. The pump 33 is provided
with a suction inlet 36 extending through an
opening in the side wall of sump 24 into lower por
35 tion of the sump 24 through which, during actu
clear the wash arm. The rails 5|! of the structure
it are shown shorter in length than the width of
the tank in so that a clearance space is provided
ation of the pump 33, washing liquid will be drawn
for discharge through pump outlet 33. The suc
tion inlet is formed with an attaching ?ange 36’
adapted to be bolted in liquid tight relation about
40 the opening through the sump wall. The upper
portion of pump outlet 38 is ?anged as indicated
at 38' for attachment to the ?anged end 39' of a
pipe 39 extending through an opening in the lower
inclined wall 23 of the washing compartment of
45 the tank Ill. Preferably bolts pass through
?anges 33’ and 33' and into a shouldered portion
of wall 23 to close the opening through which pipe
39 passes. Mounted in pipe 39 and held in place
by nut II is a rod 42 providing a bearing for sup
porting the wash arm 2|). The upper end of pipe
39 communicates with a central opening in the
rotary wash arm to provide passages for the flow
of water from pipe 38 to the wash arm 20. Dur
' ing operation of the device, water is circulated by
55 the pump from the sump to the wash arm where
it is discharged at high velocity against the
articles to be washed, drains from the tank into
the sump, and is again recirculated by the pump.
The rinse arm 2| is preferably of rotary type
60 generally similar to the wash arm 20 and, as
between the ends of the members 50 and the 30
upstanding walls of the tank for the passage of
the cover member l2 of which a portion is adapted
to be received within the tank when it is moved to
open position. The vertically extending portion
of the rinse pipe 44 is preferably arranged at the 35
side of the tank intermediate the vertical planes
passing through the spaced trunnion axes. This
pipe as shown is within and adjacent the side wall
of the cover member, and. passes upwardly be
tween the cover and the side rail 50.
40
The cover member I2 is preferably of approxi
mate semi-cylindrical form and is shown substan
tially semicircular in cross section. The curved
shell or circumferential portion Gil is provided
with parallelly extending end portions iil which 45
merge gradually into the curved portion 60 to
provide a structure of su?‘lcient depth within the
limited confines of the radius of the member 60.
The cover structure is completed by parallel side
walls 52. The shape of the cover member I2 is 50
proportioned to serve as a de?ecting surface so
that jets of wash water striking the cover will be
directed back against the articles being washed.
Spaced sets of trunnions 53 are carried by the
opposite side walls 62. The trunnions provide 55
parallel axes which are preferably spaced an
equal distance on opposite sides of a vertical plane
extending longitudinally through the center line
of the cover l2 and provide pivotal supports upon
which the cover member l2 may be rotated to 60
shown, is pivotally supported at 43 from a pipe
provide an opening at either of opposite ends of
structure 44 which may be connected to a suitable
source of supply of rinsing water.

machine in suitable racks such as illustrated at
45; these racks being of such size as to be readily
received upon the track structure it of the wash
ing machine. Suitable rack supporting tables or
70 shelves shown at 4B are shown provided at sub
stantially the level of the track structure so that
the article carrying racks 45 may be moved easily,
and without lifting, into and out of the washing
machine. Suitable connecting brackets 41 may
75 be provided, as shown, for supporting the tables
and inwardly so that as the casing i2 is moved the
one pair oi.’ trunnions 53 may rotate in the corre
sponding bearing seats 55 while the opposite pair 70
of trunnions may move upwardly in a curved path
without interference from the supporting seats.
The cover mounting is such as to permit free
cover movement without the objectionable noise
, of metal to metal impact upon closure. As shown. 75
2,128,008
particularly in Fig. 'l, a trunnion 83 is con
structed as a cylindrical stud IN] having an end
?ange III which is fixed to the cover side wall
52. Rotatably mounted on the stud H0 is a
metal sleeve H2 which has on its outer surface
a yielding material such as an encircling band
of rubber H3. The rotatable part is held in
place on the stud by provision of a washer ill
that is attached to the stud end by a screw iii.
The washer is preferably somewhat smaller in
diameter than the rubber band and, as shown,
10
provide an opening approximately equal to the
height of the washing chamber as defined by
the cover member in closed position. The end
Iii that is received within the tank moves down
wardly between the lip ii of the tank and the
adjacent overhanging end of the track 50, passes 10
under the path of travel of the overhanging end
is substantially the same diameter as the metal
sleeve. Free rotation is afforded by movement
of the trunnion stud on the metal sleeve, and
freedom from the noise of metal to metal impact
15 upon closure of the cover is provided by engage
ment of the yielding rubber band with the trun
nion support or bracket 84.
The cover I! is provided with suitable handles
or grips Gil by which it may be moved. The han
20
dles 88, positioned at opposite ends of the casing
portion Bil, are provided with lugs 69 which, in
open position of the cover member l2, are‘adapt
ed to engage the lip ii of the tank Ill to limit
the movement of the cover member. The edges
25 of the tank and the edges of the cover member
which are parallel to the tilting axis of the cover
member are termed herein for purposes of de
scription the "ends” of these respective parts,
30
35
and the edges of the tank and cover member
which are perpendicular to the tilting axis are
termed the "sides"; but it is to be understood
that this implies no limitation as to the di
mensions or shape of these parts. The trunnions
83 are positioned so that as the cover member is
moved to open position, the balance of weight,
or center of gravity, of the cover member will
be shifted to a position to the outside of the
supporting trunnions 63 to maintain the cover
member
in open position.
40
Suitable limiting means are incorporated in
the open ends of the bearing seats 85 to prevent
movement of the cover I! beyond the normal
open positions determined by the lugs 69. As
shown, the limiting means comprise curved latch
45 ing recesses 12 which extend from opposite sides
of the trunnion“ supporting members 64 and are
so positioned that as the cover l2 rocks about
one pair of trunnions as a pivot the opposite pair
may move out of engagement with the bearing
50' seats without. resistance.

the lip 15. when the cover member is moved
from- closed position to an open position, one
of the ends 6| moves downwardly into the tank

to bodily move out of their bearing seats 85'
about the point of engagement of the stop 88
55 with tank III as a pivot, such movement beyond
the normal open position is restrained by engage
ment of the trunnions GI within their latching
recesses 12. In closed position the downwardly
extending edges of the cover member II, as desig
nated by the numeral 13 for the end portions GI
and the numeral ‘II for the side walls 62, extend
within the open top of the tank ID, as defined by
the lip I5, an amount su?lcient to provide an
effective seal against the passage of washing
65
?uid during operation of the machine even
though the cover member does not actually con
tact with the tank in. As shown, the end por
tions 22 adjacent the lip it are ?ared outwardly
at 15 to receive the edges ‘ll of the cover mem
ber. The con?guration or curvature of the sur
faces 15 is such that any water from the jets
or splashed against the surfaces will be de?ected
into the tank and will not pass through the
75 clearance opening between the edges ‘II-‘N and
of the wash arm 20, and comes to rest when the
lug 69 contacts with the lip ii; the degree of
opening being limited to avoid contact with the
15
supporting members 54 of the track.
By providing a cover member with parallel
spaced trunnions, which permit the cover mem
ber to open to either of opposite ends, articles
to be washed may be inserted within the ma
chine at one end and, after washing, may be 20
readily removed from the opposite end of the
machine by merely shifting the cover member l2.
This arrangement of parts permits the washing
machine to be installed against a wall of a room
and requires for its installation a space substan
tially equal to the horizontal dimensions of the
tank structure since the cover member, in open
position, is received within the tank and stands
substantially within the con?nes of the tank
area. When it is desired to disassemble the ma 30
chine, as for the purpose of cleaning it, the entire
cover member I! may be easily removed by mere
ly lifting the trunnions 83 out of engagement
with the yoke like supporting bearings 64. The
track structure I! and the strainer 28 may then 35
be lifted out. Removal of the stand pipe Mi per
mits the sump 24 to drain so that the entire
interior of the machine is then exposed and
readily accessible.
Referring now to Figs. 4, 5 and 6, a machine is 40
shown of a type which is adapted for use in re
stricted areas, such as when positioned with its
back to a wall or in a corner of a room so that
the interior may be reached from only one end.
The machine is provided with a cylindrical open 45
bottom casing or cover member Ill having an
upper wall of substantially semi-circular cross
section comprising a curved surface It and op
posed parallel side walls 82 upon which are pro
vided aligned trunnions ll positioned to one side 50
of a vertical plane extending through the longi
tudinal center line of the cover 80. Suitable
brackets 86 are provided on the tank II’ for the
pivotal support of the trunnions II and to permit
the cover 80 to be moved from a closed position, 55
in which the open top of the tank is enclosed, to a
position providing an opening which is approxi
mately equal to the height of the wash chamber
as defined by the cover member when in closed
position. As shown, the upper portion of the
tank IB' isprovided with a ledge II having a
portion extending across the front end 22 of the
tank, and continuing portions 8!’ which extend
along opposite sides 22' of the tank to points
short of the vertical plane passing through the
trunnion axis. The upper surface of this ledge
is below the top edge of the tank, and the bottom
edge I! of the cover in closed position lies just
over the surface of the ledge, providing a sub
stantially leak-proof construction about this por
70
tion of the tank and cover, and at the same time
providing freedom of upward opening movement
of this part of the cover. The portions 8!’ of the
ledge along the sides of the tank terminate as
, shown at about the vertical plane of the trunnion 75.

2,128,008
axis, so that the rear end of the cover is permitted
to freely move down into the tank. To the rear
of the vertical plane passing through the trunnion
axis, the open edge of the tank I0’ is provided with
an inturned ?ange 10 which, in closed position of
the cover member, is. engaged by an outwardly
turned ?ange extension ‘ll of the cover member.
The inturned ?ange ‘iii of the tank and the out
turned ?ange ‘H of the cover member extend
10 across the rear edge of these parts and thence
forwardly to approximately the vertical plane
passing through the trunnion axis. The over
lapping of ?anges 10 and ‘H provides an e?ective
seal between the tank and cover member to re
15 strain the passage of washing liquid at this portion
of the respective parts.
A suitable handle 93 is
provided on the cover member for convenience in
moving the cover member. The trunnions 84 are
so positioned and the curvature of the cover
20 member portion Bi is so proportioned that as the
cover member is moved to open position the bal
ance of weight or center of gravity will move to
a position beyond the trunnion pivot point so that
the cover member will be maintained in open posi
tion and will be held in such position by engage
ment of the surface of the portion Bi with the
inner surface of dense ‘III of the tank III’.
A rack supporting track structure I4’ is pro
vided and, like the structure I4, is readily remov
able. As shown, the track structure ll’ comprises
parallel horizontally extending rails 90 having up
turned ?anges 9| for the guidance of a rack 45
and is provided with a limiting rear ?ange 92
which limits the insertion of a rack to a position
substantially central within the washing machine.
The tracks 90 are preferably positioned at a level
about or slightly above the plane of the open edge
of the tank ill’ so that racks may be inserted or
withdrawn without the necessity of lifting them
over the edge of the tank.
A suitable shelf ex
tension 91 may be attached to the tank structure
of the machine and positioned at the level of the
tracks 90 to aid in the handling of the dish carry
ing racks. The track structure it’ is shown sup
ported by means of spaced members ill that ex
tend forwardly toward the front of the tank and
terminate in end portions 95 that are telescopi
cally received within suitable horizontal sockets
98 provided adjacent the ledge 88 at the rack
receiving side of the tank, and by laterally pro
iecting members 98 that extend from the oppo
site sides of the track structure and terminate in
end portions 99 that are received by a downward
inter?tting movement within sockets or grooves
I00 formed in the upper faces of the ledge por
tions 88'. The rack support is thus in the form
of a cantilever having an overhanging rear end
which permits free passage of the adjacent por
tion of the cover member down within the tank
beneath this overhanging end of the support, and
beneath the path of travel of the overhanging
end oi’ the wash arm. The side rails 80 of the
rack supporting structure are spaced inwardly
from the inner surface of the side walls or the
tank so that the lower edges of the sides of the
cover member fit within and between these rails
and the side walls of the tank when the cover is
in closed position. The track structure H’ may
be readily disengaged from mounted position by
70 vertical withdrawal of the members 08 from the
supporting grooves I00 followed by a horizontal
rearward movement of the structure I4’ to dis
engage the members “ from the sockets 95.
The
vertically extending portion of the rinse pipe 44
75 is preferably arranged as shown at the side of
the tank adjacent the vertical plane of the trun
nion axis. This pipe extends upwardly within the
side wall of the cover member, passing between
the cover member and the side rail 80. The re
maining parts of the washing machine are gener
ally similar to corresponding parts described for
Figs. 1, 2 and 3.
,
There is thus provided a washing machine of
compact construction having an easily accessible
washing compartment, and which is adapted for
installation in positions, such as against a wall,
which permits e?lcient utilization of kitchen
space. The cover member of the machine is so
arranged that it may be opened to a position sub
stantially equal to the height of the wash cham 15
ber, and is maintained in such position by its own
weight while standing substantially within the
?oor area of the machine. Articles to be washed
may readily be inserted within and withdrawn
from the machine on an easily removable track 20
structure which is so positioned as to avoid inter
ference with the cover member which, in open
position, is adapted to be received within the case
ing. Simple and effective means are provided for
retaining the washing ?uid within the machine 25
during operation. A construction is provided
which permits the machine to be readily disas
sembled for cleaning.
