HOOKING RING- FOR A MAss sUsrENnEn T0 nELEAsINe nEvIoEs.

Application filed 'June 29, 1925. Serial No. 40,364.

To all whom it may concern:

Be it known that we, Ronnn'r ALKAN and GEoRGnsLnsoURn, citizens of the French Republic, both residing at Paris, France, have invented certain new and useful Improvements 'in a IIooking Ring for a Mass Suspended to Releasing Devices, of which the following is a specification.

This invention relates to a ring or loop allowing to suspend a mass to a releasing device with automatic hooking and arranged in such a manner as to allow the use of a simple lifting apparatus to secure the .hooking or hanging of the mass to the releasing device.

This ring which may be used for instance with projectiles, mail bags and the like thrown from airshlps 1s characterlzed by the presence of three eyes: one for the pas sage of the suspension hook, onefor the attachment of the mass, one for the attachment to the lifting gear, these three eyes being arrangedin such a manner that, when the mass is suspended to the lifting gear, the eye for the attachment to the mass takes a position which is vertical in relation to the former one, while the eye of the sus pension hook is located at a certain distance from this vertical line in such a position that the mere lifting or hoisting of the mass or body brings the eye adapted to be attached to the suspension hook .to such a suitable position relatively to the suspension hook forming partof a releasing device of a known system and of such form that the passage for the hoisting rope is left entirely free.

When the ring is hooked and when it is possible to slacken the lifting cable, the ring is slightly shifted and the point of fastening or attachment to the mass places itself vertically to the contact point between the ring and the hook.

A form of construction of this ring is shown by way of example in the accompanying drawing in which: I

Fig. l is a perspective view of the ring.

Fig. 2 is a side view thereof partly in section.

Fig. 3 shows the ring in the position of rest.

Fig. 4 shows, on a smaller scale,the ring in the hoisting position.

Fig. 5 shows the ring when hooked.

In this drawing, 1 is the eye for the hooking of the ring and2 isthe eye which is used for attaching the lifting gear 8, the

hoop 8 ofwhich passes through the slot I and is engaged into the shaft 6. This shaft 6 which is put in position for the hoisting operation and whlch is removed after the mass has been hooked or fastened, is steadied during the hoisting operation through wedging between the faces a and Z) on the one hand and the face 00f the lifting loop on the other hand. This shaft 6 can more over be stopped through the medium of a shoulder or projection 6 of the free end or by means of a pin or a safety pin which 4, the ring is in balance between two equal and opposite powers: 1st, the weight of the I load P exerted upon the fastening point m of the mass; 2d, the lifting strain H exerted upon the fastening point n of'the cable 8. In this position, the hooking or fastening eye 1 is thrown beyond the vertical of the suspension point and comes into the suitably arranged hook C of the releasing device. The upper edge of the ring pushingthe upper face. of the hook opening causing the revolution and the closure of the throwing in device.

The ring is then fastened. lVhen the cable or rope 8 is slackened (Fig. 5), the ring assumes such a position that the point on, at which this ring is secured to the mass takes under the action of weight a vertical position relatively to the booking or fastening point 0.

The loop of cable 8 can then be unhooked and the body or mass 9 remains simply suspended to the hook of the releasing de- According to the above described arrangements the ring shows the following features:

1. The ring can be turned down over the mass in the position of rest.

2. In the hoisting position, the eye securing the attachment or fastening to the suspensionhook of the releasing device is re InOVediEflOHl the hoisting line.

3. the position of fastening to the revice.

leasing device, the eye for attaching the hoisting cable is removed from the vertical of the suspension point.

lVe claim A suspension ring for a mass or body adapted to be secured to a releasing device, characterized by the fact that it comprises,

in combination, an eye for fastening the mass to be suspended, then, thereabove, an eye for the purpose of fastening to a lifting or hoisting gear, and further above, an eye for the attachment to the releasing gear,
