Abstract
Abstract An apparatus for separating particulates, as dust, dirt, sand, snow and the like, from air being directed to an air cleaner of an internal combustion engine. The apparatus has a cylindrical housing surrounding a separation chamber. Located within the housing is a sleeve having a central outlet passage for carrying cleaned air from the chamber. A plurality of circumferentially spaced vanes attach the sleeve to the housing and provide an inlet passage open to the chamber for directing the air and particulates into the chamber. An impeller rotatably mounted on the top wall of the chamber has a plurality of circumferentially spaced blades. The blades are located in a contiguous relationship with respect to a second opening in the housing. Movement of air through the chamber causes the disc to rotate, whereby the blades pump air and particulates out of the second opening. The rotating impeller produces a positive pressure at the point of discharge of the second opening to insure a flow of air carrying the particulates through the discharge opening.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
222 words
An apparatus for separating particulates from a gas carrying particulates comprising: a generally tubular housing having a side wall surrounding a chamber, wall means attached to said side wall closing one end of said chamber, an inlet passage open to the other end of said chamber adjacent the side wall, means within the inlet passage for directing the gas and particulates into the chamber in a circular direction whereby the particulates move outwardly by centrifugal force, a first outlet passage substantially coaxially extending into and open to the chamber for carrying gas separated from a substantial part of the particulates out of the chamber, said first outlet passage having an inlet opening located in the central portion of said chamber, a second outlet passage spaced from the first outlet passage in said side wall providing a passageway for gas and particulates from the chamber, rotatable impeller means located in the chamber operable to move gas and particulates out of the chamber through the second outlet passage, said rotatable impeller means having first means directed toward the first outlet passage responsive to gas flow to rotate the impeller means, and second means on the outer peripheral portions thereof to move gas and particulates out of the chamber through said second outlet passage, and means mounting the rotatable impeller means on the wall means.
Claim 2
Independent Claim
222 words
An apparatus for separating particulates from a gas carrying particulates comprising: a generally tubular housing having a side wall surrounding a chamber, wall means attached to said side wall closing one end of said chamber, an inlet passage open to the other end of said chamber adjacent the side wall, means within the inlet passage for directing the gas and particulates into the chamber in a circular direction whereby the particulates move outwardly by centrifugal force, a first outlet passage substantially coaxially extending into and open to the chamber for carrying gas separated from a substantial part of the particulates out of the chamber, said first outlet passage having an inlet opening located in the central portion of said chamber, a second outlet passage spaced from the first outlet passage in said side wall providing a passageway for gas and particulates from the chamber, rotatable impeller means located in the chamber operable to move gas and particulates out of the chamber through the second outlet passage, said rotatable impeller means having first means directed toward the first outlet passage responsive to gas flow to rotate the impeller means, and second means on the outer peripheral portions thereof to move gas and particulates out of the chamber through said second outlet passage, and means mounting the rotatable impeller means on the wall means.
Claim 3
Dependent Claim
46 words
The apparatus of claim 1 wherein: the means mounting the rotatable impeller means on the housing includes a bearing assembly for rotatably connecting the impeller means to the wall means for rotation about an axis generally aligned with the longitudinal axis of the first outlet passage.
Claim 4
Dependent Claim
37 words
The apparatus of claim 1 wherein: the wall means is a generally flat top wall, said rotatable impeller means comprising an impeller located in the upper portion of the chamber adjacent the top wall of the housing.
Claim 5
Dependent Claim
23 words
The apparatus of claim 1 wherein: said first means on the rotatable impeller means are paddle means extended toward the first outlet passage.
Claim 6
Dependent Claim
17 words
The apparatus of claim 1 wherein: the second means on said impeller means has downwardly projected portions.
Claim 7
Dependent Claim
34 words
The apparatus of claim 1 wherein: the housing has an upright sleeve having the first outlet passage open to the center portion of the chamber, and means attaching the sleeve to the side wall.
Claim 8
Dependent Claim
33 words
The apparatus of claim 6 wherein: the means attaching the sleeve to the side wall comprise inclined spaced vanes to direct the gas and particulates moving into the chamber in a circular direction.
Claim 9
Dependent Claim
71 words
The apparatus of claim 1 wherein: the rotatable impeller means has a cone-shaped center portion directed toward the first outlet passage and the second means comprise blade members on the outer peripheral portions of the impeller means, said blade members having portions aligned with the second outlet passage whereby on rotation of the impeller means the blade members pump gas and particulates out of the chamber through the second outlet passage.
Claim 10
Dependent Claim
19 words
The apparatus of claim 8 wherein: the second outlet passage is an elongated circumferential slot in the side wall.
Claim 11
Dependent Claim
46 words
The apparatus of claim 1 wherein: said second means comprise blade members attached to the impeller means aligned with the second outlet passage whereby on rotation of the impeller means the blade members pump gas and particulates out of the chamber through the second outlet passage.
Claim 12
Dependent Claim
17 words
The apparatus of claim 10 wherein: the second outlet passage is an elongated slot in the housing.
Claim 13
Dependent Claim
21 words
The apparatus of claim 10 wherein: the impeller means has a downwardly directed center portion directed toward the first outlet passage.
Claim 14
Dependent Claim
69 words
The apparatus of claim 1 wherein: the second outlet passage in the side wall is located adjacent the outer portions of the impeller means and said impeller means includes blade members attached to the outer peripheral portions thereof in general alignment with the second outlet passage, whereby upon rotation of the impeller means, the blade members pump gas and particulates out of the chamber through the second outlet passage.
Claim 15
Dependent Claim
14 words
The apparatus of claim 13 wherein: the second outlet passage is an elongated slot.
