GEORGE ARTHUR MICKEIlSON, OF VANCOUVER, BRITISH COLUMBIA, CANADA ASSIGNOR OF ONE-HALF TO JAMES MQLAGAN MITCHELL, OF VANCOUVER BRITISH COLUMBIA, CANADA.

MARINE TRANSFER APPARATUS.

Application filed March 31, 1921.

To all whom it may concern:

Be it known that I, Gnoncn ARTHUR MIOKELSON, a citizen of the United States,

and a resident of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Marine Transfer Apparatus, of which the following is a specification.

My invention relates to improvements in marine transfer apparatus,and the object of my invention is to provide an apparatus of this nature which has a wide range of utility and which is cap-able of being employed with great facility in the unloading of cargoes carried in barges, scows, or other vessels,

enabling such work to be carried out expeditiously and with great convenience so that discharging and transferring operations are effected with the maximum economy and efficiency. 7

I attain this object by the construction illustrated in the accompanying drawings in which Fig. 1 is a side elevation of the apparatus.

Fig. 2 is a sectional end view taken through the line 2-2 of Fig. 1 showing method of transferring cargo from a scow or barge.

Fig. 3 is an end view showing method of discharging on to wharf.

Fig. 4 is a detail view of the hinge construction at the lower end of the elevating conveyor.

Figs. 5 and 6 'aredetail views showing 35 method of detachably connecting the transverse conveyor.

Similar figures of reference indicate similar parts throughout the several views.

1 indicates a floating structure, of scow formation, on which are erected towards each end bridge like structures, indicated generally by the numerals 2 and 3, consisting of braced side columns 4 5 and 67 respectively connected together at their upper 45 ends by longitudinal members 8 and 9 and transverse members 10and 11, and pivotally connected at their lower ends to suitable brackets 12 secured to, the columns 4-5 and 67 are booms 13 the upper ends of which are maintained in any position to which they may be raised or lowered by lines or falls 14.v 15 indicates, a donkey engine and 16 a boiler therefor, while 17 indicates a suitably mounted shaft provided with a bevel gear Serial No. 457,316.

meshing with a bevel gear 19 secured to a vertical shaft 20, and which shaft is rotated by the gear 19.

The shaft 20 is square and extends upwardly the full height of the structure, belng rotatably supported at its upper end by any suitable means, and it passes freely through a block 21 capable of being raised or lowered by means of a cable 22, one end of the cable being secured to the block while its free end is passed over a sheave 23 and carried to the donkey engine 15. Vertically slidable on the shaft 20 and rotatably connected thereto by a sliding key is a bevel gear 2 1 which meshes with a gear 25 secured to the head end shaft of an inclined conveyor 26 arranged longitudinally of the structure 1 and the gear 24 is supported on the block 21 so that lowering or raising the block also lowers or raises the gear 241, maintains both gears 24 and 25 in mesh, and also lowers or raises the head end of the conveyor 26 when required.

27 indicates a cross conveyor the head end of which is supported on a vertically movable block 28 in a position to receive discharge of material from the conveyor 26, and the block 28 may be raised or lowered to raise or lower the head end vof the conveyor 27 by means of a cable one end of which is secured to the block while its opposite end is led to the engine 15. The length of the conveyor 27 is such that it can extend on to a wharf, indicated by the numeral 28*, when the structure 1 is brought alongside same, its outer end being preferably supported on a roller 29, and for the manipulation of this conveyor booms 30 are provided, these booms being pivotally connected at their lower ends to the side columns 5 and suitably guyed at their upper ends so that they may be used for other purposes besides the manipulation of the conveyor.

The lower end of the conveyor 26 is supported on the deck of the scow 1 towards the end thereof and connected to it by a link arrangement, indicated by the numeral 31, is the head end of a longitudinal outwardly extending conveyor 32 the tail end of which is supported by means of suitable tackle 33 hung from the upper end of a boom 34 pivotally connected at its lower end to. the side column 6, the tacklebeing operated as re" through said block, a gear on the conveyor head end shaft, a bevel gear rotatably connected to said vertical shaft vertically slidable thereon and meshing with the said head end shaft gear, said bevel gear being supported on said block, and a cable connected at one end to said block and at its opposite end to a power machine.

3. A marine transfer apparatus comprising, a floating structure, an inclined conveyor mounted longitudinally thereon having its tail end close to the deck of the structure and its head end elevated to above a wharf level, a substantially horizontal conveyor the head end of which is link- I connected to the tail end of the inclined conveyor, its tail end extending outboard from the structure, and means for carrying up the said tail end.

4:. A marine transfer apparatus comprising, a floating structure, an inclined con-' veyor mounted longitudinally thereon having its tail end close to the deck of the structure and its head end elevated to above a wharf level, a substantially horizontal conveyor extending outboard from the structure the head end of which is link-connected to the tail end of the inclined conveyor whereby it may be superposed thereon, a shaft rotatably mounted on one side of said horizontal conveyor and extending longitudinally of the same, and a gear rotatably connected to said shaft slidably mounted thereon.

5. A marine transfer apparatus comprising, a floating structure, an inclined conveyor mounted longitudinally thereon having its tail end close to the deck of the structure and its head end elevated to above a wharf level, a substantially horizontal conveyor extending outboard from the structure the head end of which is link-connected to the tail end of the inclined conveyor whereby it may be superposed thereon, a shaft rotatably mounted on one side of said horizontal conveyor and extending longitudinally of the same, a gear rotatably connected to said shaft slidably mounted thereon, and a conveyor extending at right angles tosaid horizontal conveyor having its head end adapted to be detachably supported on the said longitudinal shaft, said conveyor being provided on its head end shaft with a gear adapted to mesh with the said slidable gear.

6. A marine transfer apparatus comprising, a floating structure, an inclined conveyor mounted longitudinally thereon having its tail end close to the deck of the structure and its head end elevated to above a wharf level, a substantially horizontal conveyor extending outboard from the structure the head endof which is link-connected to the tail end of the inclined conveyor, a shaft rotatably mounted on one side of said horizontal conveyor extending longitudinally of the same, a gear rotatably connected to said shaft slidably mounted thereon.

a conveyor extending at right angles to said horizontal conveyor having its head end adapted to be detachably supported on the said longitudinal shaft, said conveyor being provided with a gear adapted to mesh with said s-lidable gear.
