Application January` 213, 1947, Serial No. 723,714

This invention relates to parachutes and provides novel forms of parachutes and a method of making them, The invention has particular application to toy parachutes, but also to the making of inexpensive parachutes for various other purposes, for example the support of signals;

fiares and targets.

'Ihe invention provides a parachute construction which is extremely simple and very inexpen` sive to produce. Contrary to the conventional practice of attaching separate shroud lines to a parachute canopy, I propose to make both the canopy as well as all the shrouds from a single piece or blank of foldable material. Such material may be paper, or fabric such as silk or rayon, or any other suitable synthetic or plastic material which is strong and light enough and adapts itself to folding into a small space.

The various objects, features and advantages of this invention will appear more fully from the detailed description which follows accompanied by drawings showing for the purpose of illustration preferred embodiments of the invention. The

invention also consists in certain new and original features of construction as well as combination of steps hereinafter set forth and claimed. Although the characteristic features and steps of the invention which are believed to be novel will be particularly pointed out in the claims appended hereto, the invention itself, its objects and advantages, and the manner in which it may be carried out may be better understood by referring to the following description taken in connection with the accompanying drawings forming a part of it in which:

Figure 1 is a plan view of a square blank from which a substantially square parachute with four shroud lines may be formed;

Figure 2 is a modified form of blank for a substantially square parachute having four shroud lines, pairs of which are connected;

Figure 3 is a blank for a substantially triangular parachute;

Figure 4 is a blank for a substantially circular parachute;

- vFigure 5 is a perspective view of an opened parachute formed from the blank shown in Figure 1;

Figure 6 is a perspective view of an opened parachute formed from the blank shown in Figure 2;

Figure 7 is a perspective view of an opened parachute formed from the blank shown in Figure 4; and

v .Figure 8 shows a blank in which shroud lines` 4 claims* (enfle-s6) are formed by convolute cuts resulting in particularly long shroud lines.

f In the following description and in the claims various details will be identied by specific names ifor convenience.' The names, however, are intended to be as generic in their application as the art will permit. y

Like reference characters refer to like parts in thel several figures of the drawings.

Inthe drawingsaccompanying, and forming part of, this specification a certain specific disclosure of the invention is made for the purpose of explanation of broader aspects of the invention, but it is understood that the details may be modifled in various'respects without departure from the principles of the invention and that theinvention may be applied to other structures than the ones shown.

f The blank A in Figure 1 may be cut from paper or kfabric or any other material light and strong enough and adapted to be folded into a small space, rice paper, silk and rayon being particul'arly suited as materials for the blank. The blank is substantially rectangular in outline thus permitting blanks to be cut in multiple from sheets or rolls of material without waste.V The blank A is .cut along cutlines II, I2, I3 and I4 extending substantially parallel to, but spaced from, the outer .edges I5, I6, I 1 and I8 of the blank. These cuts form strips I9, 20, 2| and 22 of the material which constitute shroud lines or shroud portions and are connected to the central portion 23 of the blank, forming the canopy of the parachute, along uncut portions 24, 25, 26 and 21. The cut lines II, I2, I3 and I4 terminate for this reason at some distance from one another leaving the portions 24, 25, 26and 21 uncut, wide enough, considering the tear strength of the material of the blank, to prevent tearing of the uncut portions when the parachute is in use.

The ends 28, 29, 30 and 3| of the strips, remote from the respective uncut portions, are adapted to be connected together in any suitable manner, for example bya suitable clip or clasp of sheet metal of the type generally used for connecting sheets of paper together, assuming the parachute is intended to be used as a toy.

-The blank B shown in Figure 2 is likewise rectangular in outline. It is bordered by outer edges 32, 33, 34 and 35. Two internal cut lines 36 and 31 separate two shroud line forming strips 38 and 39 from the remainder 40 of the blank, the remainder forming vthe canopy. Each strip 38 and 39 represents two shroud lines connected at the center at 4I and 42, the ends of the shroud lines terna] cuts extending along, but spaced from the outer edge of the blank, into shroud-forming strip portions and a main portion forming a canopy, the strip portions being connected to the canopy at both ends along uncut portions, the intermediate portions of the strips being adapted to be connected together for support of parachute ballast; and a metal clip connecting together said strips at said intermediate portions and providing centered ballast for said parachute.

4. A parachute comprising a canopy and shroud lines, both canopy and shroud lines being formed from a single sheet of foldable material by convolute cuts extending along, but spaced from, the outer edge or" the blank and spaced from one another, said cuts separating shroud line-forming strips from the remainder of the blank, the strips being connected to the remainder of the blank along uncut portions; and a metal clip connecting together the ends REFERENCES CITED The following references are oik record in the nie of this patent:
