CLEANING AND REMOVAL DEVICE
Abstract
This is a device for cleaning and removal of contaminants from
various areas in which cleaning is accomplished by a jet of liquid
properly contained to avoid splashing and to concentrate the
cleaning effect and removal effect, in which a rubber cup is used
to contain and assist in cleaning and removal without contamination
of adjoining areas.

Claims
I claim:
1. A jet cleaning device comprising a housing having first and
second fluid containment and passage chambers therein, the first of
said chambers being provided adjacent one end with means to connect
to a fluid source, and means at its other end adjustably to pass
fluid into the second fluid containing and passage chamber, said
second fluid passage chamber being provided at its end opposite the
adjustable fluid passing means with an enlarged shielding means
surrounding a discharge opening within said shielding means, and in
which said shielding means is non-detachably affixed to said fluid
passage body.
2. The device of claim 1 in which a fluid dispensing tip projects
within said shielding means.
3. The device of claim 2 in which said shielding means comprises a
suction cup means.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS
This Application is related to my co-pending Application, Ser. No.
851,698 filed Aug. 20, 1969, and now U.S. Pat. No. 3,672,380.
BACKGROUND OF THE INVENTION
1. Field Of The Invention
This invention is in the general field of cleaning devices and
particularly pertains to a device adpatable to clean limited areas
by jet action and so arranged that overspray and the like are
contained within a very limited, confined area.
2. Description Of The Prior Art
I am acquainted with a great deal of art in this field. The field
of cleaning, and particularly cleaning by means of a jet stream, is
an extremely crowded field.
The great requirements for appropriate cleaning within limited and
concentrated areas, and particularly where liquid pressures and/or
corrosive materials may be employed, has led to many developments
designed to eliminate the many problems inherent.
Some of the U.S. Pats., for example, which might be deemed to be in
the general field are as follows: No. 1,804,874; No. 2,736,906; No.
2,086,149; and No. 937,458.
I have examined the foregoing Patents and other devices related to
this field of endeavor and have come to the conclusion that there
was still the need of a greatly improved device which could be made
quite economically, controlled easily, and used widely. Such a
device is the result of my investigation, development and inventive
work, and is represented by this Patent Application.
SUMMARY OF THE INVENTION
This invention employs any type of liquid being delivered by
appropriate pressure means. In its most common application, the
device might use ordinary water pressure. In more sophisticated
applications, the same device is suitable for the use of caustic or
acid materials, material containing abrasives or detergents, steam
jets, and the like.
I have now devised a new and unique arrangement by which some
certain known devices have been changed, altered, and reconfigured
so as to provide a simple, easy to use, and inexpensive device for
providing an economical, simple and safe jet stream cleaner.
I have accomplished this highly desirable effect, but heretofore
unrecognizable and uneconomical effect, by combining a shielding
device, with a built in nozzle adapter, which is easily connected
to a common garden hose.
It is an object of this invention to provide a new and unique jet
cleaning device utilizing a flexible and suctionlike shielding
device for concentrating the action of a jet stream together with a
means for economically providing such jet stream.
It is a further object of this invention to provide a device as
heretofore mentioned, in which by a unique combination, an ordinary
household garden hose may be used for providing a concentrated jet
cleaning device.
It is a further object of this invention to provide a device as
described above suitable to carry additional fluids other than
household water fluids.
The foregoing and other objects and advantages of this device will
be clear to those skilled in the art, upon reading the following
detailed description in conjunction with the attached drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a partially broken away perspective of a preferred
embodiment of a device utilizing the principles of this
invention;
FIG. 2 is an enlarged partial cross section of an alternative
device to that shown in FIG. 1; and
FIG. 3 is a partially broken away perspective of the device of FIG.
1 in use.
DESCRIPTION OF A PREFERRED EMBODIMENT
This device as disclosed in FIG. 1 is seen to consist of a
shielding device 12, which is essentially the same as a rubber
suction cup, having a neck 14, into which is inserted by a threaded
connection, a nozzle having a handle 20, and which, through
principles well-known in the art, controls the flow of the liquid
into such suction cup from garden hose or the like 30, which is
threadedly connected to the nozzle arrangement.
In FIG. 3 is illustrated the identical item of FIG. 1, in which the
nozzle arrangement has been depressed at 20 to allow the
introduction of liquid under high pressure through the
intercommunicating liquid passage 49, to work upon and ultimately
obliterate stains or the like which may be upon a floor or other
area.
In the alternative arrangement shown in FIG. 2, there is shown the
garden hose 130, the handle 120, the shielding arrangement 114, the
shield arrangement 112 and the ultimate fluid-dispensive tip
149.
In my previously described Patent Application, I had contemplated
the use of a connector to connect items already on the market. In
the present device, I have shown two alternatives, the alternative
shown in FIG. 1 and FIG. 3, utilizing a standard nozzle, but also
utilizing a premolded shielding device having a female thread
arrangement so adapted as to receive the nozzle device. In FIG. 2,
there is illustrated a shielding arrangement in which the nozzle
itself is molded with the shielding arrangement, by techniques
well-known in the art, so as to provide single connection to a
garden hose 130.
In use, the pressure of a fluid or the like is exerted through the
nozzle against any stain or the like existing upon a surface or in
an intercommunicating aperture of the surface.
By pressing, properly, against the surface to be cleaned, and by
alternately using the nozzle arrangement as desired, pressure
suction or the like may be formed on the area being cleaned or such
additional cleaning action as may automatically occur.
The embodiment of this invention shown and described is fully
capable of achieving the objects, advantages and operating
effectiveness of the invention. However, modifications may occur to
those skilled in the art without departing from the inventive
concepts disclosed, and the exact embodiment shown is for
illustrative purposes and not for the purpose of limiting the
effect of this invention.
