STATES v- PATENT-:1 ioFric my r 7 2,480,318 .1; I r s ne AND LOADING GEAR v i Thomas D. Bowes, Cynwyd, Pa. 7 I f I V: I 1 A'ppl icIation February 8, 1945, Serial No. 57 6,8 8 1, K V I My invention is desighe'a to provide'improved .means for loading, and unloadin av shipex'pedi- The carriage non-tiltably supports a hollow,

6 Claims. (01. 214-45) power slewed rotor or rotatable housing upon' which ismounted loadingmechanism, such as a crane, having a fulcrume'd boom provided with lifting andtopping cables. These cables may be woundon/and unwound from suitable drums driven fromfmotors housed within the'rotor and controlled from acab'mounted on the rotor, from which the translating. andv slewing motors may also 'be controlled; I I

By my improvements there is provided a relatively light, balancedloading' gear having a low center of gravity, requiring nofcounterbalancing weights or shrouds, and interposing. no obstruction to visibility or to passing under bridges when stowed and a minimum obstruction to visibility when in operation. j I

' My improved gear permits great flexibility of operation so, tha t the ship may beloaded. from a dock or lighter or both, or loaded from one while unloadin onto theother and all holds maybe prepared for battening down the hatch covers at about the same time. Furthermore the several cranes may be used individually or cumulatively according to theweight of the loadto'be lifted, and may even be" employed for assisting in the unloading of a difierent ship from that on which they are mounted I 1.

' Th characteristic features and advantages of my improvements will further appear from the following description and the accompanying drawings in illustration thereof-z In the drawings. Fig l is a top plan view of a ship embodying my invention; Fig. 2 isa side elevation of the ship shown in Fig. 1; Fig. 3 is a somewhat diagrammatic; transverse, sectional View illustrating the operation of my improved broken away; Fig;'5 is a'sidefelevation'ofthe I I z tached crane housingand of its supporting track comprised inmyinvention.

In the. em-bodimentlof my invention illustrated in the drawings, a Ship of-an'y desir d hull type has a weather deck lcontaining jhatchways 2, 3 and 4 for ingress to and egress from the forehold, mid-hold and aft-hold of the ship. I

The edges of the hatchways are bounded, by coamings 5 spaced inboard from the gunwales of the ship sufiiciently' to provide runways 6. ex.- tending longitudinally a major portion of the length of the ships holds and preferablyfrom near the forecastle 1 to near the bridge 8.

Tracks are laidalong the runways 6 and preferably each include complementary rails 9 mounted on each coaming 5, complementary rails iii mounted on a braclset H on the deck of each runway 6, and a rail l2 forming a rack lying between the rails 9-I and I0: and ;;preferably mounted on a coamingfi. a I

The complementary rails 9 are vertically spaced from one another to form a race disposed below the coaming channel I L3 in which the hatch covers H! are battened down. The rails IE3 are vertically spaced from one another to form a race'slightly above thedeck of the runwayfiw 1 Carriages [5 are movable: along the runways 6; each carriage beingi provided. with'flanged Wheels l6 engaged in: the raceformed by the rails 9 and with flanged wheels I! engaged in the race formed by the rails. 10. The rails- 9 are adapted to engage both-thetops and bottoms of the wheels "5' and the rails H] are adapted to engage both the tops and bottoms ofthe wheels I 7 so that tilting'pressure applied to thecarriage in any direction is resistedb'y' the rails 9 and Ill, which are designed'an'd mounted to withstand both up and down pressure; I

A pinion Hli'smounted-o n'eachcarriage l5 and meshes with a-rack I2. Each pinion is may be rotated, to translate its carriaga'in any suitable manner; as for instance by an electricmotor I9 connected with the'pinion l8 through the gearing 20 and shafting 2l.* f V Each carriage-comprises aframe having side beams 22 and end beams 2 3* within which is mounted an annular track 24' having upper and lower edges=fprming" circular rails, 25 and 36;. 00-

operating with complementary circular rails '21 and 28 on a cylindrical housing 29 to 'form race ways for the sets of antifriction rollers 39 andsl The housing 29fjpreferably;comprises a. watertight, ventilated,' cylinder. having an enlarged annular base 34 towhich is attachedwthe rail 28 and'a'n enlarged annular 'heail35 to which is fixed the rail 21 and on which -isfformed .a rack 36 adapted for engagemerit byfa pinion I3l; adapted the rollers being held inspaced relationto Lone the electric motors 42 and 43 housed within the, 7

housing 29 and shielded thereby frorn theweath er. The drums 40 and 4| have wound thereon the cables 44 and 45 for manipulating the hoist' 46 and boom 41 journalled on the bracket fitl ion the platform 39. A cab 49 n'ia y' be mounted on the platform 39 to house the operator and the controllers for the several electric motors.

It wi l b nderstpd that y ma ipul tin the motor controls from c'ab 4!l; a carriage l5 may be translated alo gf ai runway 6 to any desired position lll tgtfiwie of the ship, the housing 29 mayfbe slewedfabout its"vertical axis to rotate the boomj'l through any are requisiteto align the boom with anyides'ired spot on a dock, on a lighter, or inf thehold of: the ship, and the boom dl and the hoistj lfiginay be raised or lowered to pick up ordeposit'fa load'in any desired spot. .7

The mountings of theparriage i5 an d of the rotary housing 29v on antifriction supports held against eitherlupward' r; downward pressure. in their respective racesjobviates the need for counterbalances, and, wherefa load exceeds in weight the" capacity of a single" crane two or more of the cranes may be soQpositioned as to jointly manipulate such heavyloads When the cranes are not'inuse, the booms may belowered and lashed fast in the'dottcd line positions illustrated inl'Figs. 1 and 2 where they afford: no obstruction to visibility or passage'undr bridges, and even when the booms are-in use they present' 'a minimum obstruction to visibility and occasion aminimumof -inter ference with operations within the holds. The cranes may begeifectively used.iniremoving-, stacking and replacing the; hatch. covers,.and do. not interfererwith, such coilerslon-With the placing of deck loads thereon- Having described .myninvention, I claim:
