Abstract

A flexible, rapid-lift rate, rapidly positioned missile loader with sufficient pitch-roll-yaw freedoms to accelerate weapon loading and the like. The missile loader poses the missile on a long spring column of air leaving it free to be ''''float'''' positioned to final indexing. Air is induced into bellows type lifting elements by a low pressure powered blower. Transverse positioning of the loader carriage is easily accomplished through the provision of air-actuated lift outrigger wheels.

BACKGROUND OF THE INVENTION A bellows type lifting element 20 is supported on carriage frame 15 and in turn carries a cradle 22 on the top portion thereof. Toggle- arm members 24 and 25 fastened between carriage frame 11 5 and cradle 22 are positioned fore and aft on vehicle for the purpose of steadying the cradle while being raised and while in the raised position, as shown in FIG. 2. Nevertheless, there is sufficient play in the bellows arid toggle-arm memfitting 13.

causing great difficulty in final indexing of missile to launcher. Indexing to final position was then performed through complicated and time-consuming cranking and leveling of the missile into place.

The present lifting device is a wheeled missile transporting and lifting vehicle which employs low pressure air operating over a large surface to lift a missile supporting tray toward and away from the missile loaded position. The missile in its supporting tray can then be readily positioned with sufficient three degrees of freedom to index rapidly with the attach fittings.

STATEMENT OF THE OBJECTS THE INVENTION It is an object of the invention to provide a flexible flotation, rapidly positioned missile loader. Other objects, advantages and novel features of the invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings wherein:

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 illustrates theuse of the device of the present invention for loading a missile for attachment onto an aircraft. I 7

FIG. 2 shows a perspective view of the missile loader with the missile cradle in raised position.

FIG. 3 is an end view of the present device with cradle in lowered position and carrying a missile.

FIG. 4 shows an enlarged detail view of an embodiment for locking the transverse wheel (outrigger) assembly in lowered position.

FIG. 5 is an enlarged sectional view of a portion of FIG. 4 illustrating means for air actuating the transverse wheels.

DESCRIPTION OF'THE PREFERRED EMBODIMENT Referring to the drawings, like numerals refer to like parts in each of the figures. As shown in FIG. 1 the missile loading vehicle 10 of thisinvention is maneuverable in the direction of the arrows to position the missile 12, for example, in the general area beneath the attach fitting 13 on the aircraft wing. The vehicle can be towed about on its regular wheels 14 and attached to the carriage frame 15 steered bymeans of linkagelG coupled with towbar I7.

A low pressure poweredblower 30 is used to induce air into the bellows lifting element 20. One or more bleeder type air valves 32 can be positioned on the cradle or bellows, or elsewhere on the vehicle as desired to bleed off any excess air pressure for ease in positioning or floating the missile beneath the attach fitting 13.

Transverse positioning of the missile loader carriage 15 can be easily accomplished by means of the outrigger wheels 34. A pair of outrigger wheels 34 are provided on each side of missile loader 10. Each of the wheels is attached to a support arm 36 which in turn is fastened to a shaft 37 rotatably mounted in brackets 38 so that each pair of wheels may be raised or lowered, when desired, as shown in FIG. 3. Brackets 38 are attached to a plate 56 beneath frame 15, hereinafter described. A locking means 40, shown in greater detail in FIG. 4, for example, is used to retain the outrigger wheels 34 in raised or lowered position. Shaft 37 rotatably. fits through holes in guideplates 42 and 43 which are also attached to a plate 56 beneath frame 15 as hereinafter described- A latch plate 45 having an aperture 46 therethrough is attached to shaft 37, and by means of a latch pin 48 which passes through apertures 50. and 51 in the guide plates and through aperture 46 each pair of outrigger wheels may be locked in the loweredposition. By raising a pair of wheels and passing latch pin 48 through apertures 52 and 53 in the guide plates and aperture 46 in the latch plate the outrigger wheels can be locked in the raised position.

With the outrigger wheels locked in theraised position the vehicle canbe readily moved about on wheels 14. When both pairs of outrigger wheels 34 are locked in lowered position the upper portion of carriage frame 15 supporting the bellows element 20 and wheels 14 can be raised slightly to permit transverse movement of the vehicle onthe outrigger wheels. A preferred means for raising'carriage frame 15 and wheels 14 is shown in the cross-sectional view of FIG. 5. Beneath frame 15 is a flat plate 56 provided with a seal 58 which fits against the inside of frame 15. Brackets 38 and guide plates 42 and 43 are fastened to plate 56 for securely mounting shaft 37 and outrigger wheel support arms 36. The plate 56 and seal 58 arrangement permits pneumatic pressure or the like from low-pressure blower 30, for

flange 62 supports the edge of plate 56, and thus brackets 38 and wheels 34.
