Abstract
Abstract A dispenser for single sheets of material from a stack of such sheets is provided in which an air blower flutters at least the top portion of such a stack until the top sheet thereof reaches the intake manifold of the fan thus serving as a valve to shut off the flow of air and stop the fluttering of the top portion of the stack. Upon removal of the sheet from the intake manifold, either manually or automatically, the cycle is repeated.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
103 words
A sheet dispenser comprising a container for a stack of sheets to be dispensed, a blower having an outlet in said container positioned to impinge air against the edges of sheets in said stack, an inlet for said blower positioned above said container and said stack, and said dispenser being free of any valve means for controlling the air blown from said blower outlet other than the top sheet in said stack, whereby, during operation, the top sHeet is moved into covering relationship with respect to said inlet and serves as the sole means for stopping the air being blown from said outlet.
Claim 2
Dependent Claim
103 words
A sheet dispenser comprising a container for a stack of sheets to be dispensed, a blower having an outlet in said container positioned to impinge air against the edges of sheets in said stack, an inlet for said blower positioned above said container and said stack, and said dispenser being free of any valve means for controlling the air blown from said blower outlet other than the top sheet in said stack, whereby, during operation, the top sHeet is moved into covering relationship with respect to said inlet and serves as the sole means for stopping the air being blown from said outlet.
Claim 3
Dependent Claim
102 words
A sheet dispenser comprising a container for a stack of sheets to be dispensed, a blower having an outlet in said container positioned to impinge air against the edges of sheets in said stack, an inlet for said blower positioned above said container and said stack, and said dispenser being free of any valve means for controlling the air drawn into said inlet other than the top sheet of said stack, whereby, during operation, the top sheet is moved into covering relationship with respect to said inlet and serves as the sole means for stopping the air being drawn into said inlet.
Claim 4
Dependent Claim
102 words
A sheet dispenser comprising a container for a stack of sheets to be dispensed, a blower having an outlet in said container positioned to impinge air against the edges of sheets in said stack, an inlet for said blower positioned above said container and said stack, and said dispenser being free of any valve means for controlling the air drawn into said inlet other than the top sheet of said stack, whereby, during operation, the top sheet is moved into covering relationship with respect to said inlet and serves as the sole means for stopping the air being drawn into said inlet.
Claim 5
Dependent Claim
59 words
The device of claim 1 wherein said dispenser is also free of any valve means for controlling the air drawn into said inlet other than said top sheet, whereby, during operation, the top sheet when moved into covering relationship with respect to said inlet also serves as the sole means for stopping the air being drawn into said inlet.
Claim 6
Dependent Claim
144 words
A sheet dispenser comprising a container for a stack of sheets to be dispensed, a blower having an outlet in said container positioned to impinge air against the edges of sheets in said stack, said container having an open top, in air intake manifold positioned above said container and spaced above a stack of sheets in said container, at least one air intake opening in said manifold opening downwardly toward the open top of said container, said intake manifold being connected to the intake of said blower, and said dispenser being free of any valve means for controlling the air blown from said blower outlet other than the top sheet in said stack, whereby, during operation, the top sheet is moved into covering relationship with respect to said inlet and serves as the sole means for stopping the air being blown from said outlet.
Claim 7
Dependent Claim
144 words
A sheet dispenser comprising a container for a stack of sheets to be dispensed, a blower having an outlet in said container positioned to impinge air against the edges of sheets in said stack, said container having an open top, in air intake manifold positioned above said container and spaced above a stack of sheets in said container, at least one air intake opening in said manifold opening downwardly toward the open top of said container, said intake manifold being connected to the intake of said blower, and said dispenser being free of any valve means for controlling the air blown from said blower outlet other than the top sheet in said stack, whereby, during operation, the top sheet is moved into covering relationship with respect to said inlet and serves as the sole means for stopping the air being blown from said outlet.
Claim 8
Dependent Claim
143 words
A sheet dispenser comprising a container for a stack of sheets to be dispensed, a blower having an outlet in said container positioned to impinge air against the edges of sheets in said stack, said container having an open top, an air intake manifold positioned above said container and spaced above a stack of sheets in said container, at least one air intake opening in said manifold opening downwardly toward the open top of said container, said intake manifold being connected to the intake of said blower, and said dispenser being free of any valve means for controlling the air drawn into said inlet other than the top sheet of said stack, whereby, during operation, the top sheet is moved into covering relationship with respect to said inlet and serves as the sole means for stopping the air being drawn into said inlet.
Claim 9
Dependent Claim
143 words
A sheet dispenser comprising a container for a stack of sheets to be dispensed, a blower having an outlet in said container positioned to impinge air against the edges of sheets in said stack, said container having an open top, an air intake manifold positioned above said container and spaced above a stack of sheets in said container, at least one air intake opening in said manifold opening downwardly toward the open top of said container, said intake manifold being connected to the intake of said blower, and said dispenser being free of any valve means for controlling the air drawn into said inlet other than the top sheet of said stack, whereby, during operation, the top sheet is moved into covering relationship with respect to said inlet and serves as the sole means for stopping the air being drawn into said inlet.
Claim 10
Dependent Claim
59 words
The device of claim 4 wherein said dispenser is also free of any valve means for controlling the air drawn into said inlet other than said top sheet, whereby, during operation, the top sheet when moved into covering relationship with respect to said inlet also serves as the sole means for stopping the air being drawn into said inlet.
Claim 11
Dependent Claim
210 words
A sheet dispenser comprising a container for a stack of sheets to be dispensed, a blower having an outlet in said container positioned to impinge air against the edges of sheets in said stack, said container having an open top, an air intake manifold positioned above said container and spaced above a stack of sheets in said container, at least one air intake opening in said manifold opening downwardly toward the open top of said container, said intake manifold being connected to the intake of said blower, said intake manifold being fixed in position in a plane at an angle to the plane of the top of said stack, a first rotatable roller positioned adjacent said manifold in a position to be contacted by one side of a sheet held against said intake manifold, a second rotatable roller positioned to be moved from a first position removed from said first roller to a second position in which said second roller is in contact with said first rollEr with said sheet clasped between said rollers, means to move said second roller from said first position to said second position and back again, and means to rotate one of said rollers it least while said second roller is in said second position.
