This invention relates to a washing machine provided with means
for attaching the same to a vehicle wheel, and whereby clothes may
be washed by power furnished from the vehicle, it being only
necessary to jack up a wheel of the vehicle and attach the washing
machine to one of the drive wheels.
An object of the invention, therefore, is to provide a washing
machine which may be attached to one of the drive wheels of an
Another object of the invention is to provide a washing machine
comprising a minimum of parts with means for readily mounting the
same on one of the drive wheels of a motor car or truck.
An additional object of the invention is to provide a portable, light
weight and collapsible washing machine intended for campers,
those who live in trailers, and other travelers, with means for
attaching the same to one of the drive wheels of any type of motor
Yet another object of the invention is to provide a portable washing
machine provided with means for centrifugally drying the clothes in
the machine following the washing operation.
Another object of the invention is to provide a washing machine
composed principally of complementary shells which may be
nested, one within the other, In order to occupy a minimum of
space in carrying the same from place to place.
Other objects will appear throughout the specification.

The washing machine of the present invention is of especial value to
campers and those who live in trailers, as it provides a ready means
for quickly washing and drying clothes. The washing machine
utilizes the power of any automobile engine and it is so constructed
that it may be, readily attached to any of the automobiles and most
of the trucks on the market today. Ease of assembly and economical
construction are among the outstanding features of this invention.
In the drawings, the letter A designates generally the washing
machine. The washing machine consists of a pair of shells 10 and
12. These shells may be joined together to form a waterproof
washer by means of the joint shown in Figures 1 and 3. The shell 10
is provided with a flange 14. This flange fits over the rims of
standard motor vehicle wheels which carry 15 or 16 inch tires.
Where 17 inch tires or larger tires are used, the flange will fit within
the flared portion of the tire rim. The opposite rim of the shell 16 is
provided with an offset flange 16 and an inner cylinder 18 in order
to provide a circular recess for the reception of a ring 20 preferably
composed of soft rubber or rubber-like material. The two shells,
when fitted together as shown in Figure 1, provide a truncated
cone. Shell 12 has a flange 22 which is adapted to fit over the skirt
18 and engage the rubber ring 20. The larger end of the shell 10 is
closed by a partition 24, which partition is inset from the flange 14.
The smaller end of the shell 12 is provided with a head or end wall
26 having a central opening for a rubber gasket 30, which may be
attached thereto by any suitable means. Mounted upon the interior
surface of shell 12 and extending transversely across the same are a
plurality of spaced vanes or agitators 44.
The removable cap 32 is provided with a stepped flange 34 which
seats against the gasket 30 when the cap is in closed position. There
is a viewing window 36 of glass or other transparent material in the
The window is retained in the cap by a gasket (not shown) and a
series of screws 38 arranged circumferentially of the cap.
The inner cylinder 18 is preferably of general cylindrical shape. It is
rigidly attached, such as by welding, to the partition 24. This inner
cylinder is provided with a plurality of spaced rows of apertures 40
as seen in Figures 1 and 5.
Mounted upon the interior surface of the cylinder 18 and extending
transversely across the same are a plurality of spaced vanes or
Shell 10 is provided with an opening 46 and a cap 48 to provide for
filling or partially filling the machine with a washing liquid such as
water. Soap flakes may also be introduced through this opening.
Similarly, mounted in shell 12, is an opening 46' closed by a cap 48'
which is used for draining purposes.
The assembled shells are retained in proper position on a drive
wheel of an automobile by a series of straps 50, the right end of
each, as viewed in Figure 1, being provided with a hook 52. Also as
shown in this figure, the left end of each strap is provided with a
loop 54 through which is threaded the strap 56, the latter being
provided with a buckle and a series of holes numbered 58 and 60
respectively, as seen in Figure 2.
The straps are also held taut by means of the circular strap 62
which passes through loops 64 in the strap 50. Circular strap 62
may be tightened by means of buckle 66 which engages a series of
holes 68 in the other end of the strap.
Referring again to Figures 1 and 5, there is a cylindrical
protuberance in shell 10, indicated by the numeral 70, having a cap
72 whereby to accommodate the end of the usual wheel axle and to
provide a water-tight fixture at the large end of the shell 10.
Assuming that it is desired to wash clothes in the washer, one of the
drive wheels of the car is jacked up so that the wheel is free of the
ground. The two shells of the washer are next assembled so that
they form a truncated cone. and the assembly is placed against the
vehicle wheel, and the straps are applied. The assembly is held in
the position shown in Figures 1 and 2 by the harness that includes
the four straps 58. The hooks 52 of these straps are first hooked
over the outer flange of the shell 12, and after the strap 56 has been
placed in the position shown in Figure 1. the strap 62 is inserted
through the opening and tightened by means of the buckle 66 and
If the clothes have not already been placed in the receptacle, they
arc now placed in the machine through the opening 28 which is
now closed by the cap 32 and held in position by the clamps 74.
Before the cap 48 is inserted in place, the washing powder or soap
may be poured through the opening 46.
The entire assemblage now being water-tight, water is introduced
through the opening 46 and the cap 48 is then placed on this
opening, it being assumed that cap 48' is in position over the
opening 46' of shell 12.
The motor is now started and the wheel is rotated at a speed which
should not exceed approximately 25 miles per hour.
Following the washing operation, the rotation of the wheel is
stopped with the opening 46' at its lowermost position as shown in
Figure 1. Cap 48' is then removed and the water is drained out of
When drying the clothes following the washing operation, the cover
48 is removed. The wheel is rotated at high speed and. of course,
the washer rotates at this speed. Centrifugal force causes the water
to be forced from the clothes, through the perforated cylinder 18
and into the space formed by the cylinder and the truncated cone
10. Due to the shell's taper, there is a component of the centrifugal
force which causes the water to slide along the shell surface to seek
the largest diameter of the shell, the water finding its way out
through the opening 46 under centrifugal action. It will be noted
that the opening 46 rotates within the fender area of the car and the
water is thus confined to this area.
After drainage of the water. the clothes may be rinsed by
introducing fresh water through the opening 46, the caps 48 having
been replaced before the rinsing operation begins. Following the
rinsing operation the water is drained through the opening 46' with
the car wheel stationary. Following this operation, the wheel is
rotated at a speed of at least 25 miles per hour.
All idling should be done in second gear and the idling speed
includes the washing and rinsing operations.
It is to be understood that the drawing and description are
to be considered as illustrative of one form of the invention and that
the invention may take other forms, as we do not desire to be
limited in the practice of this invention except as indicated by the
