Abstract
Abstract A gaseous-fluid-operated conveyor is provided for advancing fluidizable material, and nonfluidizable material including packages, and for mixing fluent materials, with controlled temperatures if desired. The conveyor includes a channel with side guide walls and with a bottom wall or floor having two components, a deck plate of metal or plastic with spaced and staggered longitudinal slots supported by a direction-imparting supporting grill structure such as a metal honeycomb inclined from the horizontal. A wind box below the supporting structure has gaseous fluid such as air, heated or cooled as desired, supplied thereto to supply the impelling force for the materials to be conveyed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
129 words
A fluid-actuated conveyor comprising a connection to a source of gaseous fluid under pressure, a conveyor unit having a wind box with which said connection is in communication, said conveyor unit above said wind box having an elongated deck for movement of material therealong, said deck having a lower supporting portion having a plurality of passageways imparting with respect to said deck downstream and impelling and normal and supporting components to gaseous fluid discharged from said wind box, and an upper relatively rigid cover sheet mounted on said supporting portion in blocking relation to certain of said passageways and having a plurality of openings communicating with others of said passageways for discharge of gaseous fluid directed therethrough by said supporting portion and for impelling material by said downstream component.
Claim 2
Dependent Claim
129 words
A fluid-actuated conveyor comprising a connection to a source of gaseous fluid under pressure, a conveyor unit having a wind box with which said connection is in communication, said conveyor unit above said wind box having an elongated deck for movement of material therealong, said deck having a lower supporting portion having a plurality of passageways imparting with respect to said deck downstream and impelling and normal and supporting components to gaseous fluid discharged from said wind box, and an upper relatively rigid cover sheet mounted on said supporting portion in blocking relation to certain of said passageways and having a plurality of openings communicating with others of said passageways for discharge of gaseous fluid directed therethrough by said supporting portion and for impelling material by said downstream component.
Claim 3
Dependent Claim
21 words
A fluid-actuated conveyor as defined in claim 1 in which said upper cover sheet has said openings elongated along said deck.
Claim 4
Dependent Claim
16 words
A fluid-actuated conveyor as defined in claim 2 in which said openings are in staggered relation.
Claim 5
Dependent Claim
19 words
A fluid-actuated conveyor as defined in claim 2 in which said openings are in transversely spaced and staggered relation.
Claim 6
Dependent Claim
23 words
A fluid-actuated conveyor as defined in claim 1 in which said upper cover sheet has the openings therein in the form of slots.
Claim 7
Dependent Claim
18 words
A fluid-actuated conveyor as defined in claim 1 in which said lower supporting portion is of honeycomb construction.
Claim 8
Dependent Claim
14 words
A fluid-actuated conveyor as defined in claim 2 in which said deck is flat.
Claim 9
Dependent Claim
20 words
A fluid-actuated conveyor as defined in claim 2 in which said deck is transversely concave between its opposite side margins.
Claim 10
Dependent Claim
29 words
A fluid-actuated conveyor as defined in claim 1 in which additional means is provided for changing the temperature of the gaseous fluid prior to its passage through said deck.
Claim 11
Dependent Claim
20 words
A fluid-actuated conveyor as defined in claim 1 in which said upper cover sheet is of synthetic plastic sheet material.
Claim 12
Dependent Claim
108 words
In a fluid-actuated conveyor a conveyor unit having a fluid pressure chamber, means for supplying fluid under pressure to said chamber, said conveyor unit having a deck with a face along which articles are movable, and means for supplying fluid from said chamber for impelling articles along said deck face, said last-mentioned means including members having portions providing longitudinally elongated fluid-jet-forming passages extending toward said face and said deck face having portions providing longitudinally elongated discharge openings of a length substantially greater than its widths disposed lengthwise of said deck face and with which said jet-forming passages are in communication for delivery of fluid through said discharge openings.
Claim 13
Dependent Claim
108 words
In a fluid-actuated conveyor a conveyor unit having a fluid pressure chamber, means for supplying fluid under pressure to said chamber, said conveyor unit having a deck with a face along which articles are movable, and means for supplying fluid from said chamber for impelling articles along said deck face, said last-mentioned means including members having portions providing longitudinally elongated fluid-jet-forming passages extending toward said face and said deck face having portions providing longitudinally elongated discharge openings of a length substantially greater than its widths disposed lengthwise of said deck face and with which said jet-forming passages are in communication for delivery of fluid through said discharge openings.
Claim 14
Dependent Claim
82 words
A fluid-actuated conveyor comprising a conveyor unit having a fluid pressure chamber, means for supplying fluid under pressure to said chamber, said conveyor unit having a deck with a face along which articles are movable, and means for supplying fluid from said chamber for impelling articles along said deck face, said last-mentioned means including portions having openings at said deck face of a length corresponding to a multiplicity of times the width of said opening and disposed lengthwise of said deck face.
Claim 15
Dependent Claim
82 words
A fluid-actuated conveyor comprising a conveyor unit having a fluid pressure chamber, means for supplying fluid under pressure to said chamber, said conveyor unit having a deck with a face along which articles are movable, and means for supplying fluid from said chamber for impelling articles along said deck face, said last-mentioned means including portions having openings at said deck face of a length corresponding to a multiplicity of times the width of said opening and disposed lengthwise of said deck face.
