AMUSEMENT DEVICE Filed Dec. 13, 1955 INVENTOR AT TORNEY Patented Apr. 4, 1939 PATENT Orr-"10E AMUSEMENT DEVICE Stanley Swltlik, TrentonyN. J. Application December 13; 1935, Serial No. 54,183

7 Claims.

This invention relates to an amusement and training device that may be used, for instance, in amusement parks and wherein a parachute canopy is elevated and then permitted to fall in simulation of a free drop, and wherein a release of the canopy when it reaches a predetermined 'heightmay be automatically accomplished, and wherein the release may be manually accomplished prior to the time that the canopy reaches said predetermined height.

The device in which my invention is incorporated includes a parachute canopy, the skirt of which is maintained open by a rigid ring, a hoist for raising the canopy and the harness that is attached thereto, vertical guides for the canopy in its descent, buffers for gradually arresting the fall of the canopy and means for manually releasing the canopy from the hoist.

The invention of this application includes \the canopy with its means for maintaining its skirt extended, the manual release and means for carrying the harnessed load in such manner that the ring is not deformed when it contacts with the buffers.

In the drawing: I

Figure 1 is .a view of the entire assemblage partly broken away for the sake of convenience of illustration, a

Figure 2 is a fragmentary sectional view of the c opy.

Figure 3 is a similar view looking at rightangles to Figure 2,

Figure 4 is a perspective view of the vent ring and one element of the separable fastener by which the canopy is attached to the hoist .and

Figure 5 is a view of the ripcord ring.

The canopy consists of the usual panels or segments l at certain of the seams of which the shroud lines 2 of the usual form are attached. These shroud lines extend to and are attached to the lift webs 3 of the harness. It is, however, to be understood that instead of a harness any type of carrier may be used and either may be used detachably.

A rigid ring I is located at the skirt of the canopy and the canopy is attached to this ring by a series of detachable means such as releasable straps 5. These detachable means are located at the points where the panels are joined, and are thus intimately associated with the shroud lines.

The diameter of the ring 4 is less than the diameter of the skirt of the canopy and the is inflated the panels will take their usual inflated form.

For convenience of transportation and assembly the rigid ring 4 may be made of a plurality of sections detachably joined together by suitable means 6 such as shown in Figure 3.

The vent of the canopy at the top thereof is surrounded by a rigid ring I which is attached to the canopy in a suitable manner and carries a spider 8. This spider in turn carries one element 9 of a separable fastener by means of which the canopy is attached to the hoist.

I have conveniently illustrated the hoist b'y disclosing the cable I0 thereof. This cable carries the other member of the separable fastener.

In the drawing I have illustrated the separable fastener as consisting of the element 9 to which I have already referred and a plate or body II that is attached to the cable ID. A hook I! is pivoted at I3 to the plate II and is of such form that when in a vertical position it is adapted to automatically become disengaged from the element 9 to release the canopy. A trip lever H is pivoted on the plate II at l5 and is adapted to engage the extended end of the hook 12 so as to maintain the hook out of its vertical position and in its holding position as shown in Figure 1. It is to be noted that the force exerted by the end of the lever is directed at the pivot point of the trip lever II.

The spring acts as a 'detent to maintain the connection It in position on the lever ll .before the separable iasteneris tripped.

' This spring tends to hold-the lever 12 against movement in either clockwise or counterclockwise directions leaving the release to the force applied to the end of the lever. However, it is to be understood that the cooperation of the lever l4 and the hook I: insures against disengagement without the spring.

When the trip lever It is actuated about its pivot it passes beyond the extended end of the hook l2, moving it out of its path of travel, and releases the hook so that it is free to swing into its releasing position under the influence of the weight of the jumper. The trip lever I4 is so formed as to allow the movement of the hook into this position.

A ripcord device l1 having a separable connection I! with the trip lever H, which separable connection is maintained in engagement with the trip lever, extends from the trip lever to a point adjacent the harness. Preferably this ripcord carries the-ordinary ripcord handle l9 which is located at a point adjacent the harness and may 45 tain the same extended, the canopy, having a being compressible when force is applied thereto than the remaining shroud lines.

lines may be formed of webbing of the char- 2 a taon be removably held in a pocket 20 on a lift web adapted to slide on the vertical guides 22 by means of which engagement the canopy is guided in its, ascent and descent.

Buffer springs 23 are arranged on the guides 22 and are secured thereto to 24, the springs by the contact of the eyelets 2| during the descent of the canopy. Thus the descent is bufleted.

It has been found that when all of the shroud lines are of the ordinary character and of the same lengths there is a tendency of thering 4 to deform when the buffers are engaged. I have overcome this tendency by forming the shroud lines adjacent the points of contact between the eyelets 2| and the buffers of a material relatively heavier and stronger-and relatively shorter These shroud acter used in the harness and become in reality load carrying shroud lines.

While I have disclosed certain details for the convenience of illustration I do not, wish to be limited to those details except as is necessitated by the claims.

What I claim is:

1. In a device of the class described the combination with a parachute canopy, of a rigid ring for maintaining the skirt of the canopy extended,- vertical guides with which the ring has sliding connection, buffers associated with the guides and with which the ring is adapted to contact, a harness, load carrying shroud lines connected to the ring at the points at which the ring contacts with the bufiers and additional shroud lines connected with the harness and ringbetween the first mentioned shroud lines.

device of the class described the combination with a-parachute canopy, of the rigid v ring attached to the skirt of the canopy to mainvent at the upper end, a rigid ring surrounding the vent to maintain the -vent open, a spider extending upwardly from-the latter ring and one- -element of the separable fastener attached to the 'spider.*'" 1 3. ma device of the class described, a parachute canopy, "a harness attached thereto, a rigid ring in the skirt of the canopy tomaintain the 55. same entended, a plurality of .vertical guides with which the ring is slidably engaged, means for elewaiting the canopy, load-carrying shroud lines extending from the ring at the points of engagement between the ring and the guides to the harness, and shroud lines connected to the canopy and harness between the load-carrying shroud lines.

4. In a device of the class described, the combination with a parachute canopy of a harness attached thereto, the canopy having a vent at its upper end, a hoist, a rigid ring attached to the canopy and surrounding the vent and having one element of a separable fastener thereon, a
