This invention relates to toy parachutes having for its object the provision of an improved device of the kind indicated.

Another object of the invention is to provide a toy parachute with novel means for insuring the opening of the parachute upon its descent.

Additional objects and advantages of the method and construction employed will appear more fully in the details hereinafter set forth when taken in connection with the accompanying drawings, in which,

Fig. 1 is a view of the device in collapsed form as it appears in its ascent;

Fig. 2 is an elevational View of the device as it appears while descending.

In the drawings of the preferred form of my invention, A designates my parachute, the body portion 6 of which may be of silk or other suitable fabric, provided with eyelets 7 about the periphery thereof. In the eyelets 7 the upper ends of the cords 8 are secured, the other ends of these cords being fastened in a disk 9 having a central hole 10. Through the hole 10 a central cord 1.1 is passed, which latter is secured to a small reinforcing pad or head 12 which serves as a buffer for a weight to be described hereinafter. Secured to or abutting against the pad 12 is a spring 13 which is coiled about the central cord 11, the spring 13 serving both as a shock absorber for a weight 14 slidably mounted on the cord 11 and also as a means to start the return of the weight 14 down the cord 11 after the parachute A has reached the top of its ascent. as will herenafter appear. To the end of the cord 11 a button or cap 15 is fastened, which prevents the end of the cord 11 from being withdrawn out of the hole 10.

In operation the device is folded in the manner shown in Fig. 1, and thrown or projected upwardly in any suitable manner, the weight 14 having been first permitted to abut the spring 13 as shown in Fig. 1. In its upward flight, the weight 14: will maintain substantially the position shown in Fig. 1, that is, with an end abutting the spring 13, it being observed that the resistance of-the 50 air against the exterior of the parachute A will tend to retard its upward flight, but not to materially check the tendency of the weight 1 1 to press against the spring 13 while travelling upwards. When the device has attained the maximum height to which the momentum given it causes it to ascend, the weight 14:, at the moment when the velocity has arrived at zero value, will be thrust backwardly by the spring 13, and thus urged down the cord 11 until it is arrested bythe disk 9, as shown in dotted lines in Fig. 2. The parachute A in descending will now open into the position shown in Fig. 2, and drift downwardly to the earth in the well known manner. While in the present device, the spring 13 is shown as a component part of my invention, it may be omitted if desired, but I have found that it aids in returning the Weight 14; down the string while the parachute A is descending.

It will of course be understood that the device may be modified and changed without departing from the spirit or sacrificing any of the advantages of the invention, hence I do not desire to be understood as confining myself to the details precisely as set forth, save to the extent these are circumscribed within the scope of the appended claims.

WVhat I claim as new and desire to secure by Letters Patent is:

1. A device of the kind described comprising a foldable body portion, a plurality of cords attached to said body portion in spaced relation, a central cord connected to a mid point in the body portion, a weight slidably mounted on said central cord, and a disk member operatively associated with said cords, substantially as described.

2. A toy parachute of the kind described including a foldable body portion connected to a plurality of cords, said cords being fastened to a disk slidably connected to a central element secured to said bodyportion at a mid-point thereof, and a weight slidably mounted on said element, said weight serving to further the flight of said parachute in its ascent while serving to balance said parachute while descending.

3. A toy parachute of the kind described comprising a foldable body portion having a plurality of cords afi'iXed thereto, said cords being fastened to a disk having a hole, a centrally positioned cord passing through said hole and connected to a central inner part of said body portion, a spring mounted on said cord, and a weight slidably mounted on the cord and confined between said spring and disk( at. A toy parachute of the kind described comprising a foldable body portion having a reinforcing pad, a cord secured to said pad, said cord passing through a hole in a disk, a plurality of other cords fastened to said disk and to said body portion, a Weight slidably mounted on said first mentioned cord after said' parachute has reached the limit of its upward flight.

5. A toy parachute of the kind described comprising a plurality of cords secured to a foldable body portion at one end, a disk secured to the other ends of said cords, a central element slidable in a hole formed in said disk, a button at one end of said element, a reinforcing pad fastened to the other end of said element, said reinforcing pad forming a part of said body portion and serving as a means of securing a spring coil thereto, and a weight slidably mounted on said element and coacting with said spring when said parachute is in operation.

6. A toy parachute of the kind described comprising a body portion of fabricated material, a plurality of eyelets provided in the periphery of said body portion, a corresponding plurality of cords connected to the body portion in the said eyelets, a disk fastened to said cords, a flexible element secured at a central point of said body portion and a weight slidably mounted on said flexible ele ment, said Weight abutting against the central point of said body portion when said body portion is thrown upwardly, substantially as described.

7 A toy parachute of the kind described comprising a foldable body portion of fabricated material having a central reinforcing pad, a cord secured to said reinforcing head. a weight slidably mounted on said cord, a spring coiled about the cord and fastened in said pad, a plurality of other cords secured to the periphery of said body portion and fastened to a disk slidably mounted on the cord, and means to prevent said first mentioned cord from being withdrawn completely from said disk.

In testimony whereof I have signed my name to this specification.

GEORGE JOHN GROSSMAN.
