With reference now to the drawings, and in particular to FIGS.
1 through 4 thereof, a new cat litter separator embodying the principles
and concepts of the present invention and generally designated by
the reference numeral 10 will be described.
The present invention, designated as numeral 10 includes a rectangular
housing 12 having a front face, a rear face, a top face, a bottom
face, and a pair of side faces for defining an interior space. One
of the side faces has a pair of doors 14 hingably coupled within
a rectangular cut out formed in the housing. Such doors are positioned
adjacent to the bottom face for allowing access to the interior
space, as shown in FIG. 1. The top face of the housing has a top
opening 16 formed therein adjacent to the front face thereof. An
arcuate flange 18 is coupled along an edge of the top opening which
defines a portion of a cylinder.
The housing further has a divider 20 having an inverted V-shaped
vertical cross-section. The divider is mounted between the side
walls just above the doors for reasons that will soon become apparent.
Associated therewith is an angled plate 22 mounted to both the front
and rear face of the housing and extending inwardly and downwardly
therefrom. Further, it is preferred that the front face of the housing
be capable of the being removed. To facilitate such removal, a plurality
of gripping knobs 24 are formed on the front face.
FIG. 3 depicts a pair of square containers 26 each with an open
top and a bottom face. Such bottom face has a surface area half
that of the bottom face of the housing. As such, the square containers
are adapted to be removably rested on the bottom face of the housing
and are situated within the interior space thereof between the divider.
With reference still to FIG. 3 a chute 28 is shown having a generally
Z-shaped configuration. In use, the chute is preferably removably
coupled within the interior space of the housing and easily removed
therefrom after the front face is removed. The chute is coupled
to the housing via a plurality of tab and groove combination fasteners
30.
The chute has a top angled portion 32 situated within the housing
and extending downwardly from the top opening thereof and toward
the rear face of the housing. A top face of the top angled portion
has a first screen 33 mounted in coplanar relationship therewith.
Further, a bottom face of the top angled portion has a second screen
35 mounted in coplanar relationship therewith. In the preferred
embodiment, the top face is removably coupled to the chute for reasons
to be set forth hereinafter.
The chute further includes an intermediate angled portion 34 situated
within the housing and extended downwardly from the top angled portion
toward the front face of the housing. The intermediate angled portion
has a top face and a bottom face being closed. The chute further
has a bottom angled portion 36 situated within the housing. The
bottom angled portion is extended downwardly from the intermediate
angled portion and toward the rear face of the housing. The bottom
angled portion terminates at a rear extent of the divider. Ideally,
each angled portion defines an angle of approximately 36 degrees
with respect to the horizontal. It should be noted that a bottom
face of the bottom angled portion has a third screen 37 mounted
in coplanar relationship therewith and a top face that is closed.
Further, a bottom end of each angled portion of the chute terminates
short of the front and rear wall.
As shown in FIGS. 2a & 2b, a pair of screen types are shown.
Each of the aforementioned screens consist of one of these types.
First, as shown in FIG. 2a, a first screen type 38 includes only
a plurality of linear wires spaced a predetermined distance in parallel.
Shown in FIG. 2b is a second screen type 39 including a matrix of
intersecting wires which are spaced less than the predetermined
distance. Preferably, the first screen type is employed above the
second screen type.
By this structure, cat litter having clumps of fecal matter may
be deposited within the top opening such that the cat litter sifts
downwardly into one of the containers adjacent the front face of
the housing. This is accomplished through two paths one of which
includes through the first and second screen and subsequently over
the top face of the bottom angled portion. Secondly, the cat litter
may flow through the top and intermediate angled portions and exit
via the third screen. With regard to the fecal matter, the same
may be deposited in one of the containers adjacent the rear face
of the housing by one of two paths, similar to the cat litter. Such
paths included either, through the entire chute or over the top
face of the top angled portion.
As to a further discussion of the manner of usage and operation
of the present invention, the same should be apparent from the above
description. Accordingly, no further discussion relating to the
manner of usage and operation will be provided.
With respect to the above description then, it is to be realized

invention, to include variations in size, materials, shape, form,
function and manner of operation, assembly and use, are deemed readily
apparent and obvious to one skilled in the art, and all equivalent
relationships to those illustrated in the drawings and described
in the specification are intended to be encompassed by the present
invention.
Therefore, the foregoing is considered as illustrative only of
the principles of the invention. Further, since numerous modifications
and changes will readily occur to those skilled in the art, it is
not desired to limit the invention to the exact construction and
operation shown and described, and accordingly, all suitable modifications
and equivalents may be resorted to, falling within the scope of
