O N' STEWART, or to xnesr, ALABAMA- SQ H IP -COALINGaDEVICE, i

To all whom it may concern:

Be it known that I,JOHN S; STEWAR a citizen of the United States, and residing at Lockhart, in the county of Covington and State of Alabama, have invented certain new and useful Improvements" in Ship-Coaling Devices, of which the following is a specification.

The present invention relates tothe 'class of loading and unloading and has particular reference to'new and useful improvements in ship-coaling devices.

The primary object of my invention is to provide new and useful improvements in coaling devices 'forships when at sea without the necessity of cable or other unreliable conveying apparatus between a collier' or the like and a ship to be coaled.

Another object of my invention is to provide a ship-coaling device of theclass described which may bebuilt in or permanently associated with a coal carrying ves-. sel such as a barge or the like, the loading mechanism having suitable driving means associated therewith which intthe present instance is preferably an electrical motor.

A further object of my invention is t6 provide means carried on a coaling ship whereby the delivering vessel may bemaintained at a suitablesafe distance from the receiving vessel at the sameltime affording quick transfer of the' cargo with the least amount of weight.

Other objects and advantagesto be derived from the use ofniy imprQved coaling ship will appear fromthe following detailed description and the claim, taken with the in:

spection of the accompanying drawing in Which i T T Figure 1 is a top plan view of my improved coaling shipand the: coal conducting mechanism showing the same inoperative position. a p J Fig. 2 is a longitudinal sect onal view taken on the line 22 of Fig. 1 looking in the direction of the arrows, and, i Fig. 3 is a transverse sectional view taken on a line 3 3of Fig. 1 looking inth'e direction of the arrows.

Referring more particularly to the draw ings, wherein similar characters of reference designate like and. corresponding parts throughout'the various views, 1 designates the hull of my improved vessel having the usual'bottom 2- and sides 3. The1hul1 l is. provided with fore and aft holds 4 and 5, v

respectively. The vessel may be used as a barge or lighter for towing purposes or may be self-propelled, in which event the holds 1 andb may be employed for containing propelling machinery, crews quarters, etc.

The hull of the vessel is provided with the usual weather deck 6, the forward portion of the weather deck being provided with a hatch 7, closed by a door 8,covered by a protecting grating 9. An upper deck 10 is an ranged transversely of the vessel, preferably a little forward of the midship section and a platform 11 is supported thereabove, said platform and deck being strengthened by a block 12. The hoisting mechanism of my in vention is carried on a pair of vertical stand: ards l3 and 14- extending from the keel of the vessel to a suitable point above the plat- I provide driving means for the conveyer.

16, said means in the present instance comprising an electric motor 27 the armature shaft of which is extended as at 28, mounted in a bearing 29 and having a pinion 30 there on for engagement with one of the chains 17 of saidconveyer. In order to equalize the driveon the conveyer 16 I provide a countershaft 31 mounted in a bearing 32 and having-pinions 33 on its free ends for engage ment with the first mentioned pinion 30 and a pinion 34 carried by a stub-shaft 35 mounted in a bearing 36, the last mentioned pinion being in engagement with the other chain of the conveyer 16.

, I provide a coal containing hopper or the like which is preferably located aft of the conveyer mechanism hereinbefore described, said hopper being designated 37 and having an inclined bottom wall 38, the inclination of the bottom 38 being forwardly of the ves-. sel. A plurality of openings 39 are provided in the bottom 38, said openings being normally closed by sliding 'doors 40. "A

vened for this purpose.

It will be readily apparent from an in' spection of Fig. 2 that the buckets 18 pass through a suitable opening 43 provided in the bottom wall 38 of the hopper 37. In

order to convey the contents of the hopper 37 to the buckets, I provide a conveyer, preferably of the endless type, designated 4st and being trained over rolls 15 and d6 7 mounted in a suitable frame 47 beneath the openings 39 hereinbefore referred to. The convcyer 4% ends at a point proximate to the path of travel of the buckets 18 whereby to convey the contents of the hopper 37 to 7 said buckets as desired.

Necessarily, the conveyer 4A must have some driving means and I therefor provide the driving chain I8 trained over a sprocket 49 operatively associated with the rollers 45. said chain being further trained over an idler 50 carried by one of the standards, and thence over a power receiving sprocket 51 carried by the same standard, inthe present instance the standard 14 I11 order to drive the sprockets 51, I provide a pinion 52 mounted on the shaft 53 and rotatable with the said sprockets, said pinion 52 meshing with a relatively large gear 54: carried on one of the shafts 25, the shaft being length- A hearing bracketis provided for the shaft 53 and'the extended portion of one of the shafts 25.

I provide a coal deck 56 having outwardly inclined portions .57, which portions are provided with coal directing flanges 58, whereby to convey the coal to the delivery chutes 59, arranged in a novel lDOHlltll'lg hereinafter described.

I provide means for emptying the buckets 1S automatically as the same reach a predetermined point on the coal deck, said means preferably embodying a trip member 60 pivoted'at 61 in a bracket62 mounted on the coal deck. A coil spring or the like 63 serves to normally tend to maintain the trip 60 in the lower position, a set screw 64% serving to adpist said trlp to the desired height. The conve ver arcferabl travels in a i y the direction indicated by the arrow in Fig. 2. and it will be seen as the buckets pass the trip the former are tilted as indicated to advantage in Fig. 2 emptying the contents thereof on to the coal deck and thence to the chutes. 7

In the present instance, I have shown in Fig. 1 two receiving vessels designated 65 and66, said vessels having the usual hatches (37 forming the entrances to the coal bunk-' ers. In order ,to adjust the chutes 59 to the desired height, I provide brackets 68 Copies of this patent ma beobtained for 7 hereto.

carried by the upper ends thereof. 'The brackets 68 are formed to provide rack bars 69 arranged in meshing engagement with pinions 70 carried on brackets 71 mounted on the deck 10. Cranks 72 carried'with the 7 'pinions serve to rotate the latter for raising and lowering the chute. I do not limit myself to the showing disclosed in the drawing in so far as the chute construction and adjustment is concerned, but I do lay particular stress upon the novelreceiving and conveying mechanism as well as the arrangement of the conveyer 4 1 in. the hopper 3?,

In order to prevent contact between the collier and the vessels to be coaled I pro vide fenders 73 mounted as at 74 on the sides of the collier, said fenders being adjustable in height by means of cables '75 framed over drums 76 operable by cranks 77.

From the above description taken in con nection with the accompanying drawings,

it is thought that a clearand comprehensive understanding of the construction, operation and advantages of my invention may be had, and while I have shown and de scribed my invention as embodying a specific structure, I desire that it be understood that I may make such changes on said struc tures as do iiotdepart from the spi'rit'and scope ofthe invention as described.

. What I claim as new and desire by LettersPatent is V A loading device of thecharacter described, comprising in combination. with a ship having its deck inclined and formed with a series of discharge openings, of doors for normally closing said discharge to secure openings, inclined conveying means arranged beneath said openings and extend ing longitudinally of said inclined portion of the deck, vertically disposed conveymg means including a series of buckets communicating with the hull of the ship and havinga horizontally disposed stretch at a point above the deck, said vertically dise posed conveying means communicating with the inclined conveying means whereby to permit the discharge of matter from the inclined conveying means thereinto, means in the path of the buckets on the horizontal stretch of said conveying means for tripping the buckets at a predeterminedpoint and causing the dumplng of the contents thereof, laterally inclined chutes arranged on the ship :atopposite sides of the horizontal stretch of thevertically disposed conveying means,'and means for vertically adjusting the chutes independently ofeach other. 7 1 i In'testiinony whereof I aflix my signature JOHN s. screw- RT.
