Abstract
Abstract An attachment for an industrial vacuum machine is installed in the vacuum hose line and preferably supported by a boom on such machine. The attachment separates bulky items from finer materials passing through the hose. The separator includes a vacuum-tight casing containing baffles, a downward sloping bottom and a rotary vacuum air-tight valve which may be rotated to discharge bulk material into an underlying bin, truck or car without rehandling. Materials enter the separator chamber through a hose discharging into one side and exit through a second hose leading to the vacuum machine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
A bulk separator comprising a vacuum-tight casing having an inlet, an outlet, a casing bottom, a valve in said bottom, said valve being vacuum-tight and having means to discharge bulk material separated in said casing out of said casing, an industrial vacuum machine having a machine inlet, a first hose between said machine inlet and said separator outlet; a second hose extending from said separator inlet, a boom on said vacuum machine and means on said boom to support said first hose, and a lift eye on said separator and means connecting said lift eye and said boom to support said separator.
Claim 2
Dependent Claim
102 words
A bulk separator comprising a vacuum-tight casing having an inlet, an outlet, a casing bottom, a valve in said bottom, said valve being vacuum-tight and having means to discharge bulk material separated in said casing out of said casing, an industrial vacuum machine having a machine inlet, a first hose between said machine inlet and said separator outlet; a second hose extending from said separator inlet, a boom on said vacuum machine and means on said boom to support said first hose, and a lift eye on said separator and means connecting said lift eye and said boom to support said separator.
Claim 3
Dependent Claim
80 words
A combination according to claim 1 in which said valve has a cylindrical housing having a top communicating with said casing bottom and an open valve bottom for discharge, a rotatable shaft, vanes on said shaft contacting the inside of said housing and means for rotating said shaft, whereby bulk material in the casing bottom is received between vanes, transmitted around one side of said housing and discharged through said valve bottom without substantially reducing the vacuum in said casing.
Claim 4
Dependent Claim
30 words
A combination according to claim 1 which further comprises a baffle in said casing extending from a location above said separator inlet downward-inward at an angle across said separator inlet.
Claim 5
Dependent Claim
30 words
A combination according to claim 1 which further comprises a baffle in said casing extending from a location below said separator outlet upward-inward at an angle across said separator outlet.
Claim 6
Dependent Claim
27 words
The combination of claim 1 in which said boom is rotatable to move said separator so that said means to discharge bulk is positioned over a bin.
Claim 7
Dependent Claim
68 words
In combination, an industrial vacuum machine and a separator according to claim 1, which further comprises a source of vacuum for said vacuum machine, said separator casing being shaped to cause air and waste material drawn through said second hose entering said separation casing inlet to swirl around the inside of said casing to separate heavy portions of said waste material from said air solely by swirling action.
