PARACHUTE.

Specification of Letters Patent.

Patented Dec. 31, 11918.

Application filed September 21, 1918. Serial No. 255,083.

To all whom it may concern:

Be it known that I, CAL TRo'r'rER, a citizen of the United States of America, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented certain new and useful Improvements in Parachutes, of which the following is a specification.

The primary object of the invention is the provision of a parachute especially adapted to be carried by a balloon or aircraft, whereby the craft and its passengers may descend gently to the ground without being injured by falling.

A further object of the invention is to provide-a parachute which is normally folded but is radially opened by the operator whenever desired for use, the structure possessing great strength and simplicity and mounted upon any member to prevent the same from falling violently to the earth and permitting the gradual descent thereof.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination, construction and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and then claimed.

In the drawings forming a part of this application, and in which like reference characters refer to corresponding parts throughout the several views,

Figure 1 is a central vertical sectional view taken through the device.

Fig. 2 is a top plan view thereof, and

Figs. 3 and 4 are horizontal transverse sectional views upon an enlarged scale taken upon lines HI-HI and IVIV of Fig. 1.

My parachute comprises a pole 10 having an upper portion 11 of enlarged diameter for holding a foldable canopy 12 while a ball 13 is positioned at the bottom of the pole journaled in a socket 14 provided in a member 15 adapted to be supported by the parachute.

Resilient metallic ribs 16 are provided within the canopy 12 hinged as at 17 at their inner ends to the upper end of the pole portion 11 and terminating at their lower ends in tips 18 adjacent the edge of the canopy. A flexible cap 19 is secured to the upper end of the pole 10 overlying the center portion of the canopy as well as the hinge connections 17.

A plurality of springs 20 are connected beover said pulley with its other tween the tip portions 18 and eyes 21 upon the pole portion 11, said springs normally tending to close the canopy against the pole butvbeing tensioned and radially arranged when the canopy is in its open operative position.

A disk 22 is slidably mounted upon the pole 10 provided with links 23 pivotally connecting the said disk with the tip pprtions 18. A collarv 22 is slidably mounted on pole 10 and is attached to the disk 22. An operating cord 24 is attached to the disk 22 and passes over a pulley 25 adjacent the upper end of the pole l0 and then extends downwardly to a point adjacent the supported member 15.

The disk 22 being slidable upon the pole 10 and normally held downwardly in its retracted position by means of the springs 20, it will be seen that by pulling upon the lower end of the cord 24, the disk 22 will be elevated for outstretching the links 23 and opening the canopy 12 as illustrated in Fig. 1 of the drawings.

The pole 10 is swingingly mounted upon the member 15 by the ball and socket joint 13 and 14 heretofore described for permitting swinging movement of the supported member 15 when held by the parachute upon descending through the air. The parachute possesses great simplicity as well as strength and is serviceable in preventing the loss of life when an aeroplane to which the same is attached becomes unmanageable or damaged and incapable of operation.

What I claim as new is 1. A parachute comprising a pole having an end portion of a large diameter, a canopy attached to said end portion, an overlying cap for the center of the canopy secured to the free end of the pole, ribs hinged to the pole terminating adjacent the edge of the canopy, springs connected between the pole and the ends of said ribs, a disk slidably mounted upon the pole. pivotal link connections between said disk and adjacent ends ofthe ribs, a pulley upon the pole adjacent its upper free end and an operating cord attached at one end to the disk and running end extending adjacent the lower end of the pulley.

2. A parachute comprising a pole having an end portion of a large diameter, a can opy attached to said end portion, an overlying cap for the center of the canopy secured to the free end of the pole, ribs hinged Q aeame to the pole terminating adjacent the edge over said pulley with its other end extendof the canopy, springs connected between ing adjacent the lower end of the pulley, 10 the pole and the ends of said ribs, a disk a ball upon the lower end of the pole and a slidably mounted upon the pole, pivotal link supported member provided with a socket connections between said disk and adjacent having said ball mounted therein for free ends of the ribs, a pulley upon the pole ad-- movement and supportingly attached. I jacent its upper free end, an operating cord In testimony whereof I afiix my signature. 15 attached at one end to the disk and running CAL TROTTER.
