TION OF NEW JERSEY BEENFORCING FOR PARACHUTESHIROUD COBDS Application leld September 25, 1931. Serial No.,565,172.
`Experience shows that `shroud cords tear loose from the material of which a parachute, is made, and this occurs more' frequently when the material of the parachute lis de- 3 terioratin or getting old, therefore it is the purpose o the present invention to lessen the frequency of the shroud cords tearing away. To accomplish this it is the aim to use a reenforcing, which lmay be of any shape or of any size and havino its original or starting point immediately adjacent the edge of the canopy parachute and to overlie the seam 'between the segments of the parachute, and where the reenforcing terminates immediately adjacent the edge of the parachute having a multiple of stitching to render the same secure, and a multiple of stitching through the reenforcing and through the Shroud cord where it passes through the seam and under the reenforcing,
thereby preventing tearing away of the shroud cord.
It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the Scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to clrcumstances.
The 1nvent1on comprlses further features and combination of parts to be hereinafter set forth, Shown in the drawings and claimed.
In the drawings Figure 1 is a view of a portion of a parachute, at a part where two segments of the parachute. connect, showing the application of the reenforcing at this point.
Figure 2 is a view of a portion of the parachute where the twoI segments unite by a seam, the same as in Figure 1, but showing the reenforcing spaced apart and unattached,
but about to be attached, showing how the l se ments appearwithout the reenforcing.
0 Seam comprises the segments overlapping,
.of the parachute.
the space between the stitching 4' receiving the "shroud cord 5, which extends throughout the entirety of the seam toI the apex of the parachute, the shroud' cord previous to its location in this manner having been' stretched its fullest extent.
c., or Tamron, NEW JERSEY, aconrona- A vPrior to the advent of this reenforcing a multiple of stitching (not shown) has been used back and forth over the shroud cord and through the seam at a point adjacent the marginal edge of the parachute, and with this mode of attaching the shroud cord, tearing away of the cord frequently occurs.
The reenforcing, though it maybeof any shape and of any size is preferably of V contour, a plurality of stitching 6 passing through the reenforcing 7 adjacent the edge The stitchings 6 are in addition to the usual stitching 8, which makes the hem 9 at the edge of the parachute. Additional stitching 10 is carried through the reenforcing and through the opposite edges of the seam between the two segments. A multiple ofsstitchings 11 are made or traced back and forth through the Seam and through the shroud cord, thereby making a permanent attachment of the cord, not only-through the seam'but also through the reenforcing, which not only provides a permanent attachment of the cord to the parachute adjacent its marginal edge, but renders thetearing away of the .cord less frequent, in fact reduces the tearing away of the cord to a minimum practically nil. Rows of stitchings 12 and 13 adjacent the angleedges 14 of the reenforcing,
additionally secure the reenforcing to the opposite segments of the parachute, which also reenforces the segments relative to each other. The shroud cords extend down from the edge of the parachute and are connected in the usual manner (not shown) to a parachute harf,
ness (not shown).
The invention having been set forth, what is claimed is:
V1. In a parachute, the combination with a Seam between two segments of the parachute having a hem at its edge, of a reenforcing fastened to the hem at the edge of the parachute and overlying the seam for a substantial distance, and means for attaching the `reenforoing vover the'hem, and a multiple of stitching passing throu h the reenforcin through the seam and bac and forth throu the shroud cord,r for a distance substantia y away from the edge of the parachute.Y
2. In a reenforcing for` a parachuteshroud e cord, the combination with a seam between two segments of the parachute having 'a hem at its marglinal edge,lofa shroud cord engaged lo through t e seam2 a substantiall broad re- Ienforcing having lts origin at an stitched to the hem and stitched at its edge to the two se ents of the parachute, and a multiple o stitches passing back and forththrou hthe 15 seam and back and forth through the s roud p cord and having their origin at the edge of the hem and extending from the edge of the hem and terminating at a pointsubstantially away fromt-he edge. e 20 3. jIn a reenforcing for a parachute shroud cord, the combination with a seam between two segments of the parachute-having a hem at its mar 'nal edge, of a shroud cord engaged through t e seam,l a substantially broad reg5 enforcing having its origin at and stitched tothe hem and stitched at its ed e tothe two sefgments of the parachute, an a multiple 4 o stitches passing back and forth throu h the seam and backl and forth through t e so shroud cord ahd havingtheir origin at the l edge of the hem and extending from the ed e of the hem and terminatn at a point su stantally, away from the e ge, and rows of stitches passing through the reenforcing and sa through the seam and extending from the .edge of the hem and on each side of the seam to a point substantially away from the edge of the seam. v
In testimony whereof I aix my signature. 40 STANLEY` SWITL'I-K.
