Abstract
Abstract A system and method for refurbishing and processing parachutes is disclosed including an overhead monorail conveyor system on which the parachute is suspended for horizontal conveyance. The parachute is first suspended in partially open tented configuration wherein open inspection of the canopy is permitted to remove debris and inspect all areas. Following inspection, the parachute is transported by the monorail conveyor to a washing and drying station with the parachute canopy mounted on the conveyor in a systematic arrangement which permits water and air to pass through the ribbon-like material of the canopy. Following drying of the parachute, the parachute is conveyed into an interior space where it is finally inspected and removed from the monorail conveyor and laid upon a table for folding. Following folding operations, the parachute is once again mounted on the conveyor in an elongated horizontal configuration and conveyed to a packing area for stowing the parachute in a deployment bag.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
228 words
A system for refurbishing and processing parachutes of the type having a canopy including a plurality of gore sections with radial lines delineating between adjacent gore sections extending through a generally common point to define an apex portion, said system comprising: (A) a defouling and inspection station receiving said parachute and including support means for suspending said parachute to enable a worker to openly inspect said canopy and remove debris from and untangle said parachute; (B) a washing station receiving said parachute and including means for washing said parachute as required for removing foreign matter and soiling; (C) a drying station receiving said parachute and including blower means for delivering heated air for drying said parachute; (D) a folding station including table means for receiving said parachute for final inspection, repair, and folding thereof; (E) an overhead conveyor by which said parachute is carried and suspended in a systematic arrangement to permit water and air to pass therethrough at said washing and drying stations, respectively, said conveyor including a generally horizontal conveyor path for sequentially transporting said parachute from station to station; and (F) hook means for attaching every nth radial line to said conveyor with said apex portion conveyed forwardmost where n is defined by n=2G+1, where G is the desired number of gore section depending from either side of the point of attachment to said conveyor.
Claim 2
Independent Claim
228 words
A system for refurbishing and processing parachutes of the type having a canopy including a plurality of gore sections with radial lines delineating between adjacent gore sections extending through a generally common point to define an apex portion, said system comprising: (A) a defouling and inspection station receiving said parachute and including support means for suspending said parachute to enable a worker to openly inspect said canopy and remove debris from and untangle said parachute; (B) a washing station receiving said parachute and including means for washing said parachute as required for removing foreign matter and soiling; (C) a drying station receiving said parachute and including blower means for delivering heated air for drying said parachute; (D) a folding station including table means for receiving said parachute for final inspection, repair, and folding thereof; (E) an overhead conveyor by which said parachute is carried and suspended in a systematic arrangement to permit water and air to pass therethrough at said washing and drying stations, respectively, said conveyor including a generally horizontal conveyor path for sequentially transporting said parachute from station to station; and (F) hook means for attaching every nth radial line to said conveyor with said apex portion conveyed forwardmost where n is defined by n=2G+1, where G is the desired number of gore section depending from either side of the point of attachment to said conveyor.
Claim 3
Dependent Claim
29 words
The system of claim 1 wherein said support means suspend said parachute canopy in a partially-open tented configuration enabling a worker to walk around and up into the canopy.
Claim 4
Dependent Claim
31 words
The system of claim 1 wherein said overhead conveyor includes at least one continuous overhead conveyor rail extending from said defoul and inspection station through said washing, drying, and folding stations.
Claim 5
Independent Claim
259 words
A system for refurbishing and processing parachutes of the type having a canopy including a plurality of gore sections with radial lines delineating between adjacent gore sections extending through a generally common point to define an apex portion, said system comprising: (A) a defouling and inspection station receiving said parachute and including support means for suspending said parachute to enable a worker to openly inspect said canopy and remove debris from and untangle said parachute; (B) a washing station receiving said parachute and including means for washing said parachute as required for removing foreign matter and soiling; (C) a drying station receiving said parachute and including blower means for delivering heated air for drying said parachute; (D) a folding station including table means for receiving said parachute for final inspection, repair, and folding thereof; (E) an overhead conveyor by which said parachute is carried and suspended in a systematic arrangement to permit water and air to pass therethrough at said washing and drying stations, respectively, said conveyor including a generally horizontal conveyor path for sequentially transporting said parachute from station to station; (F) said support means suspending said parachute canopy in a partially-open tented configuration enabling a worker to walk around and up into the canopy; and (G) means for releasably suspending certain ones of gore sections while leaving the other gore sections folded to provide said tented configuration, said releasable means enabling said suspended gore sections to be released and replaced by a folded gore section until all gore sections have been spread open for defouling and inspection.
Claim 6
Independent Claim
259 words
A system for refurbishing and processing parachutes of the type having a canopy including a plurality of gore sections with radial lines delineating between adjacent gore sections extending through a generally common point to define an apex portion, said system comprising: (A) a defouling and inspection station receiving said parachute and including support means for suspending said parachute to enable a worker to openly inspect said canopy and remove debris from and untangle said parachute; (B) a washing station receiving said parachute and including means for washing said parachute as required for removing foreign matter and soiling; (C) a drying station receiving said parachute and including blower means for delivering heated air for drying said parachute; (D) a folding station including table means for receiving said parachute for final inspection, repair, and folding thereof; (E) an overhead conveyor by which said parachute is carried and suspended in a systematic arrangement to permit water and air to pass therethrough at said washing and drying stations, respectively, said conveyor including a generally horizontal conveyor path for sequentially transporting said parachute from station to station; (F) said support means suspending said parachute canopy in a partially-open tented configuration enabling a worker to walk around and up into the canopy; and (G) means for releasably suspending certain ones of gore sections while leaving the other gore sections folded to provide said tented configuration, said releasable means enabling said suspended gore sections to be released and replaced by a folded gore section until all gore sections have been spread open for defouling and inspection.
Claim 7
Dependent Claim
40 words
The system of claim 4 wherein said overhead conveyor includes a parallel bar supported by rollers on said conveyor rail and a plurality of transverse hanger bars carried by said parallel bar having attachment means for attaching said canopy thereto.
