SELF-ALIGNING GUIDE FOR LOADING IN MISSILE LAUNCHING SYSTEMS Filed May 27, 1953 2 Sheets-Sheet 2 INVENTOR ROBERT E. CARLBERG 3a 7 BY SELF-ALIGNING GUIDE FOR LOADING IN MISSILE LAUNCHIN G vSYSTEMS Robert E. Carlberg, Falls Church, Va., assignor to the United States of America as represented by the Secretary of the Navy The invention described herein may be manufactured and used by or for the Government of the United States respectively.

of America for governmental purposes without the paymerit of any royalties thereon or therefor. j The invention relates to improvements in load handling equipment and more particularly to improved muzzle loading equipment formissile launchers handling elongate missiles of the type supported by fore and aft suspension lugs.

V The muzzle loading of long,-'heavy missiles provided with rigidly fixed fore and aft suspension lugs onto stationary grooved supporting rails'or guides of a missile launcher requires the exercise of a considerable amount of care not only in the preliminary alignment of the fore and aft suspension lugs forwardly of the front and rear launcher rails or guides preparatory to attachment of the missile to the launcher, but also in bodily moving 7 the missile backwardly underneath the launcher rails and maintaining parallelism of the missile and launcher arm while the missile is being supported on a cart or the like. An important object of the present invention is to pro- Pendently connected by fore and aft sets of linkage 18, 19 to the fore-anddaft crossheads is a missile loading rail or bar 20 provided on its underside with forward and aft male and female guides 21, 22 respectively.

The floating rail or bar 20 is supported during missile loading so as to havef-reedom of motion in all directions, angularly and linearly except forward and aft and in the down direction. To this end, the fore and aft sets of linkage are provided ,at their upper end portions with universal joints 23, 24 and at their lower end portions with hinge joints 25, 26 and a ball joint 27 connected to the top side of the rail and having aligning hinge pins 28, 29 and socket 30 disposed above and longitudinally of the rail. Instead of using the rigid rod 31 shown in the drawings for linking the universal joint 24 and ball joint 27' of the aft set of linkage, the use of a flexible cable (not shown) is optional. Hingedly connected to the aligned forward hinge pins 28, 29 at a lower edge 32 is a plate 33 having a cylindrical swivel housing 34 rigidly aflixed to its forward end and normal to'the lower edge 32. The lower end of the universal joint 23 includes a shaft 35 swiveling in the housing 34. The missile 36 is anelongate rocket provided with a pair of upwardly projecting relatively long rigidly attached forward suspension lugs 37, 38 having inturned vide equipment facilitating the loading of a heavy missile v i of the type provided with fore and aft suspension lugs onto the guide rails of the launcher. I

Another important object of the invention is the provision of means facilitating the loading of a heavy missile supported on a moving cart or the like into a muzzle loading launcher.

. A. further object is to provide improved missile supporting fixtures for a launcher handling elongate missiles of the type provided with fore and aft suspension lugs.

' A still further object is the provision ofimproved mis- 4 sile supporting and lifting equipment for a launcher of the above-described character.

The invention also aims to provide improved floating missile suspension equipment for a launcher of the characterdescribed.

Additionally, the invention aims to provide a missile launcher having the above-described floating missile suspension equipment with means firmly securing the missile suspension equipment against floating action during launching of the missile.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein: Y

Fig. 1 is a side view of the missile loading equipment 2 showing a missile in loaded position; and v Fig. 2 is a perspective view of the equipment with parts thereof shown in lowered position ready for suspension of a missile thereon. 1

In the drawings, which for the purpose of illustration show only a preferred embodiment of the invention, and wherein similar reference characters denote corresponding parts throughout the several'views, 10 designates the launcher arm or carrier member. of a missile fingers 39, 40, and a single upwardly projecting relatively short rigidly attached aft suspension lug 41 having outturned fingers 42, 43. On the underside of the floating rail or bar 20 at its forward end is a tapered male guide 44 'provided with side grooves 45, 46 slidably receiving the inturned fingers 39, 40 of the missile forward suspension lugs. Also on the underside of the floating rail or bar but at its after end is a female guide 47 provided with a rearwardly convergent throat 48 leading to a T-shaped groove 49 slidably receiving the aft missile suspension lug 41. i Projecting upwardly from the forward and aftend portions of the 'floating bar are triangular, preferably integral wedge members 50, 51, arranged to firmly engage against re-entrant surfaces 52,53 and 54, 55 of seats formed in the launcher arm. When the missile is to be muzzle loaded onto the launcher, the rail is lowered to a free swinging position so that the forward and aft guides 44, 47 may be readily positioned to receive the suspension lugs of the missile being loaded from a cart, and will be automatically selfaligning with the suspension lugs of the rigidly supported missile on the cart as the cart is drawn rearward-1y under the launcher rail. v By the system of hydraulic cylinders 12, 13 and sets of linkage 18, 19, the rail and missile are then raised to bring the wedge members 50, 51 into firm engagement with the respective seating surfaces 5255 whereby all motion of the floating rail 20 is prevented during firing.

Obviously many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore to be understood that within the scope of the appended claims the invention maybe practiced otherwise than as specifically deseri bed. 7
