and are connected to any suitable conventional antenna or other radiant energy receiving means on the gliding structure, such as indicated at E9 in the drawing. The control devices I5 and I8 are operatively connected by

flexible connectors

20 and 2! to the

arms

22 and 23 on the horizontal rudde member 5.

The conventional radio control device if, also mounted on the frame unit of the gliding structure, when energized, operates an actuating rod [1' connected to an arm l?" on a shaft 20 journaled longitudinally in said structure. Suitable arms 23 and 25 extend in opposite directions from the ends of the shaft 20, .and have

link members

26 and 21 pivoted thereto. The other ends of the

link members

26 and 21 are connected to

arms

28 and 29 on the ailerons l5. Impulses of proper frequency, which are received by the control device 2?, cause longitudinal movement of the rod [1' in one direction or the other and corresponding stabilizing control movements of the ailerons 15.

The conventional radio controlled surface actuating control devices l6, l1 and I8 are carried by the supporting frame structure A and may preferably be mounted on the shelf or cross member IE], intermediate the front and rear ends of said frame.

By constructing our gliding attachments in two units, namely, the supporting frame unit structure A and the gliding wing unit structure B, a plurality of the gliding attachments may be shipped with groups of these two elements detached and stacked, and each pair of the units may -be readily assembled in the field by bolting the wing structure to the upper face of the supporting frame structure A in any conventional manner, as by bolt fasteners 30, carried in brackets 3|, which are secured to the lower face of the wing structure and pass through the longitudinal boom members i.

In the embodiment of our invention, as seen in the drawings, the wing unit member B is provided with an opening 32 therethrough to permit passage of the rear bomb support !2 therethrough.

In constructing the gliding attachment, the wing unit B is preferably made of thin, light material, such as plywood, and has sufficient supporting area and proper airfoil section adaptable for gliding purposes in accordance with the weight of the largest bomb used. The unitary supporting frame A is also preferably made of wood o other inexpensive material, including the longitudinal boom members ll while the bomb engaging and securing strap members 'i-1 are preferably of thin fiat metal and are connected to the boom members i.

In the application of the attachment to a bomb, the wing unit B is first secured to the supporting frame unit A, and then placed on top of the bomb with the hangers or supporting members l2 projecting from the bomb extending upwardly intermediate the boom members I, the rear hanger l2 passing through the aperture 32 in the wing. The strap members 'l7 may then be passed around the bomb and secured together by any suitable means such as by bolts 33. The bomb and its attached gliding structure may now be elevated into engaging position and connected to the bomb release brackets I3 on the plane.

It should be observed from the drawings that the gliding wing unit structure for the bomb, when in position, lies between the bomb and the lower surface of the wing or other bomb supporting structure of the plane, and close to the latter, while the supporting frame A for the gliding attachment is secured to the bomb on one side thereof, below the gliding wing unit for the attachment. When the bomb is released at a considerable elevation, its glide angle can be determined and controlled so that it can be accurately directed by any conventional radiant energy operated sending apparatus to the target, regardless of the shifting of the target in an attempt to avoid the bcmbs contact therewith.

Having thus described our invention, what we claim and desire to secure by Letters Patent is:

1. In a dirigible gliding attachment, for a conventional aircraft bomb having a supporting means projecting laterally from one side of the bomb, adapted to be releasably secured to an aircraft for release from an elevated position, said attachment comprising a rigid substantially rectangular flat frame-like structure composed of a pair of elongated spaced side by side frame members connected together by cross-frame members at their front and rear ends, one of said cross-frame members having adjustable glide control surfaces thereon, strap members depending from the lower side of the frame-like structure, adapted to be clamped around said bomb to support the bomb between the elon gated spaced side frame members during the flight, with the bomb positioned in engagement with said cross-frame members and the laterally projecting supporting means on the bomb disposed between the two elongated side frame members, a unitary gliding airfoil wing structure adapted to be secured to said frame-like structure opposite to one of said supporting strap members, said wing structure having an opening therethrough for receiving said bomb supporting means therethrough, and means for adjusting the glide control surfaces carried by said frame-like structure.

2. In a dirigible gliding attachment for a conventional aircraft bomb having a plurality of supporting means projecting laterally from one side of the bomb in longitudinally-spaced relation to each other and adapted to be releasably secured to an aircraft for release from an elevated position, said attachment comprising a rigid substantially rectangular flat frame-like structure composed of a pair of elongated spaced side by side frame members connected together by crossframe members at their front and rear ends, one of said cross-frame members having adjustable glide control surfaces thereon, strap members depending from the lower side of the frame-like structure and connected to each of the spaced side by side frame members, adapted to be clamped around said bomb to support the bomb between the two elongated spaced side frame members during flight, with the bomb positioned in engagement with at least one of said crossframe members, and the laterally projecting supporting means on the bomb projecting through the frame-like structure between the two elongated side frame members, a unitary gliding air foil wing structure adapted to be secured to the spaced side by side frame members of said framelike structure opposite one of the bomb securing strap members, said wing structure having an opening therethrough for receiving one of said bomb supporting means therethrough, and means for adjusting the glide control surfaces carried by such frame-like structure.

3.
