This invention relates to a method of and apparatus for manipulating fairshi'ps and analogous Iighter-than-air craft and it has. for its principal object to facilitate the handling of airships, at" the same time great y.

. reducing the personnel heretofore required 1 moving both devices and the airship concurmethodconsists, of a particular I Jbile'or traveling mooring mast whereby the masts, this end in view,

in such operation. g 7 Generally statedg'the method consists of anchoring both'extremities ofan airship to mobile fore and" aft mooring: devices and rently, so 'tliat i-n docking an airship, for eX- ample, be aligned with a-dock, and both the mooring devices and ship moved into the dock.

Theapparatus used in carrying out the type of moship maybe readilymoved from one point to 1 another while being held in'bou-nds and 'yet is permitted a limited fore and aft movement relatively to the masts and has free angular play about a horizontal axis at its pointof attachment to the masts. The improved V V as above noted, are mobile, and with may bemounted to travel on track-ways or may be of thetractor type and provided with suitable treads such as those used on the well known caterpillar type of tractor.

To gain a more complete understanding of Figs. 4, 5 and 6 are, respectively, viewsin side and front elevation andiplan of another 1 form of mast for carrying out the method; Fig. 7 is a view in perspective,showing a method of berthing an airship in accord: ance with the invention'and Fig. 8 is a view, in side elevation, of a mod-- ified form of the cup and cone mounting illustrated in Figs. 1,2 and .3.

I When it. is desired to move the carriage 8 in .an' athwartship directionpthe handwheel .13 is rotated5jand through the drive connections above described, rotation isimparted to the thread shafts 18 and 18, which engage in the thread lugs or nuts secured to the carriage.

In addition tothe carriage 8,}and movable at substantially right angles W respect thereto, or in a foreand' aft direction,a carriage', '*generally indicatedat 23,"isprovided.

' respectto the athwartship traveling carriage isprovidedwith a said rack.

This carriage ismounted-on rollers 24 adapted to travel in guide tracks 25, wh ch restra n any appreciable vertical movement of the carnage, and to restrain the carriageagainst side movement, the latter is provided with additional bearing rollers 26 adapt-edto bear against the tracks (note'FigQ3). .Stops V 27 are provided at theends ofthe track rails 25 to prevent over-running of the carriage 23.

It will, be observed that the-carriage 23 is movable only in a fore aft direction with 8. This movement is controlled by means of a handwIheel-28, which is mounted on a verti- 'cal shaft- 29, the latter being provided with aworm which meshes with a wormwheel On the; platform or under the frame of the carriage 23 is a rack 33, and the shaft 32 extends acros s'and gear 32 which meshes with 31 secured on a shaft 32.

Byirotatingthe handwheel 28, the carriage ;23'may bemoved in a fore and-aft direction as desired, V v

To, permit the carriage V 23 to have free movement with the end of the ship, as is sometimes desirable,-the handwheel shaft 29'is set in an eccentric bushing 34.]By rotating this bushing through the agency of an op Veratinghandle 3? provided for this'purpose,

the, worm 30 may be released from driving I I V the how oi the ship into direct engagement engagement with the worm Wheel 31 and the carriage will th'en have a free floating movement or may be pushed orpulled hand.

In the modified form of cup and cone 0011-. nection illustrated '11'1 F1g. 8,-tl1e cup '(01' and cone 461 are adaptedto beengaged in aver tical direction-In thisconstruction the necessity of providing rotatable platform 501 on the frame v5 1S (illll'lilittted inasmuch as a rotatable connection may read ly. be pro-T vided-between the cup 701 and cone ltil. The

cup 701 is mounted by vertically adjustabld means to the carriage 2 3 -wh1chis formed;

In this. construction't-he carriage 34- is flat. dispensed with. I

g The improved mast maybe used either as a-bow or tail mast, and may be operated in a manner substantially as follows:

vVhenthe mast is used as a bow mast} it is, placed in thelan'ding field adjacent airship dock in a position such as that indicated 1? at A in Fig. 7 ,'-so that'the ship may land into the wind which will allow'the ship to,

be more easily handled andcontrolled. The ship is moved slowly up to a position where the bow or nose thereof is adjacent or slightly above the mast. It is possible to bring with the mast in several ways which may. in. clude dropping a'cable'from the nose of the ship, whichcable iswound up a suitable "winch (not shown) on the ,mast and the method requiring a very small ground crew. .Anothermethod of bringing the bow of the ship into engagingrelation with the mast is 7 by the aid of ground crewscontrolling the V shipby hand lines. The exact position of the cone 46 carried by the'mast-canl be conallow the airship to rotateabout a horizontal up on a suitable winch (not shown) on the tail mast. Or again, ground; crews with hand lines from the ship may be used for-this When the mast is used asa tail mastpor when a second mast is'emp loye'dlinconjunc-j tion with thefirst', one beingat thebow and.

the otherat the tail of the. ship the pro:

'cedure is the same as that described gaboye except that in addition the an i theship will be secured to the tailniastl This is ac complished by moying the tail mastto a position such as indicated at B in Eig. 7-,ad:

jacent the-tail of the ship; thefship being held by thebow mast "ina fairly steady po sition inasmuch as it is headingintothe wind. The position of the coneof thetail 'inast is nowfadjusted until the connection 15.

to thetail of the: ship is completed.- T0 facilitate makingthe -eonnection,; a cable-may be dropped from the tailwhich can-be wound purpose. 7.

' After the airshipfhas been anchored be: tween the two masts in the manner above described, the mast securing the tail of the andthe airship are niovedtogether intothe' ship isswung on an are about the mast securing the bow of the ship to'align theiair ship with the dock,lwhereupon the masts dock; E e 1 The rotatablemounting of-the platform 501 on the frame 5 a-llows'therotative niove ment of the masts and the'ships as described: Afterthe ship is secured between the two masts, it may be desirable to operate the handles 34. to allow the carriage23 lfree movement on the carriage 8 so that anysmall: variations in the distancejbetween .the 'niasts,

will not result in strain upon the airship.

If the same length airship is being handled continuously,..the preferrecl manne'r of. in-

stallation comprises the, provision of a straighttrack C extending on ailine out of; the dock and acircular ,trackD,iallpoin'ts of which are equidistant from the station A,

. at which station theb'ow mast is placed prior to landing of the ship. In tliis construction the masts may be readily mountedongsuit able cars 4 supported onthe traCksQWhereby sirable' to replace one'or both of-the cars4 'th'e operations above described are facilitated. e i V I Where airships of various lengths are being handled it will probably be fOundjdc with a caterpillar tractorg The operation with the masts mounted on tliecaterpillar' tractors is the same asthat' described above with respect to themasts when .Inounted on cars running on tracks.

The hereinbefore described of limb? construction enables an airship to vbe manipu lated with greater facility than has hereto-f fore been possible and at the same timeinaterially reduces the personnel required on the i-l field.
