Ridgway, Winthrop, Mass. Application May 8,1953, Serial No. 353,721 9 Claims. (Cl. 272-565) This invention relates to an amusement device such as may be installed in amusement parks and the like, and it has for its principal object to provide an amusement device which will give a person using it a sensation akin to that experienced by a parachutist when making a parachute jump.
Another object of the invention is to provide an amusement device of this type having a landing element in the form of an elongated sheet of steel or similar material which is suspended at its like curve with its upper end to said landing element.
Another object of the invention is to provide an amusement device of this type which is constructed so that the length of the free gravitational drop of the person using the device may be varied to provide a relatively short drop or a relatively long drop.
In the drawings wherein I have illustrated a selected embodiment of the invention:
Fig. 1 shows a side view of the amusement device.
Fig. 2 is an enlarged view of the top of the tower showing the carriage thereon in vertical section taken along the line 2-2, Fig. 5.
Fig. 3 is a fragmentary detail showing the manner of connecting the upper end of the landing element to the tower.
Fig. 4 is a front view of the apparatus.
Fig. 5 is an enlarged plan view of the tower showing the carriage thereon in section along the line 5-5, Fig. 2.
Fig. 6 is a sectional fragmentary view showing a portion of the track on which the carriage runs.
The apparatus comprises a tower element 1 which may have any desired height up to 75 feet, or more, and which is provided at its upper end with the means for releasing the person who is using the amusement device, which means shall be hereinafter more fully described.
Associated with the tower is a landing element in the form of an elongated sheet 2 of steel or other suitable material, the upper end of which sheet is pivotally secured to the tower 1 atan elevated point, as shown at 3, and the lower end of which is pivotally secured at 5 to a supprt'4 which is spaced horizontally from the tower. The length of the landing element 2 is such with relation to the points of suspension 3 and that said element will hang in a catenary-like curve shown in Fig. 1 with its upper end 6 elevated well above the lower end and having a position slightly inclined to the vertical, while the lower end 7 will curve laterally from the tower and terminate in a substantially horizontal portion at its lower pivotal end.
The landing element may be pivotally connected to the tower and to the support 4 in any suitable way. As shown welded thereto a head 9 which constitutes the cooperating part of said hinge, these two hinge parts being connected together by the pivotal bolt 3. A similar hinge construction may be employed for pivotally connecting the element to the fixed support 4.
The tower 1 has mounted thereon means, located above the upper inclined portion '6 of the landing element, to
lower end of the landing such person for a'gravitaupper portion of the land- The platform can be released by moving the lever 17 to the right, Fig. 2, to withdraw the latch 16 from the platform extension.
Associated with the platform is a spring 21 which is connected at one end to the under side of the platform, as shown at 22, and is connected at its other end to the carriage, as indicated at from its operative position into Mounted on the carriage 13 is closed. The front wall 27 of the housing is preferably of plate glass so that spectators can see a person who has entered the housing and is standing on the platform 14.
In'using the device, the carriage is adjusted on the rails 12 so as to bring the platform 14 over the upper inclined portion 6 of the landing element 2. The person who is to use the device will ascend to the deck 10 of the tower and enter the housing 24 through the door 25, after which the door will be locked. It will be understood that during this time the platform 14 is in its operative position and is locked therein by the locking latch 16. The operator of the device then actuates the lever 17 to release the lock for the platform and the weight of the person on the platform together with the spring 21 will instantly swing the platform from its operative horizontal position into its vertical inoperative position) When this occurs, the person occupying the housing will serve to convey the person to the lower end of the landing platform. If desired, a receiving mat 28 may be employed at the delivery end of the landing element onto which the person will be deposited.
The landing element willpreferably be provided with side walls 29 of canvas or the like which will prevent the person using the device from sliding sideways oif from the steel sheet during his journey along the length of the landing element. The upper ends of the two canvas sides are shown as connected to the tower by suitable springs 30 and the lower ends of such canvas sides are connected to posts 31 by means of other springs 32. This gives the canvas sides sufficient flexibility to accommodate any bending movement of the steel sheet 2 due to the impact of the falling person against it and the journey of such person along the lower portion of the landing element.
The length of the gravitational movement of the person using this device from the platform tothe landing eleelement can be varied by moving the carriage 13 on the rails 11. If the carriage and housing are in the position shown in Fig. 1 there will be provided a drop of a length about two-thirds the height of the tower. if the person using the device wishes to experience a shorter drop, the carriage will be moved to the right, Fig. 1, so as to bring the platform 14 over the upper portion 6 of the landing element near its upper end, as shown by dotted lines in Fig. 1. When in the dotted line position the gravitational drop through space of the person using the device will be less than that which results when the carriage and housing are in the full line position, Fig. l.
' Means are provided for automatically locking the platform in its inoperative position when it is swung into the dotted line position, Fig. 2. For this purpose there is provided a locking latch 33 which is engaged by the extension 20 of the platform when it is swung into a vertical position and which serves to automatically lock the platform in such vertical position, thereby preventing any rebound thereof as the person is gravitating through the open end of the housing.
The rails 12 are provided with stop blocks 34 at their outer ends to limit the outward movement of the carriage.
If desired the support 4 together with the mat 28 and posts 31 may be mounted for adjustment as a unit toward and from the tower 1, thereby to vary the shape of the catenary-like curve of the landing element 2. If, for instance, the support 4, mat 28, and posts 31 are adjusted into the dotted line position, Fig. l, the portion 7 of the landing element will sag below the pivotal discharge end as indicated indotted lines so that during the last part of the journey over the landing element of a person who has been dropped out of the housing will be up the inclined end portion 40 of said landing element and thereby the speed of movement of such person will be retarded.
, While I have above described my invention as embodied in an amusement device, yet used for training people for parachute jumps inasmuch as the sensation which a person experiences when released from the housing 24 and gravitating through free space on to the landing platform is very similar to that which a parachutist experiences when he makes a parachute jump.
