Application led July 16, 1909. Serial No. 508,051.

To all whom it may concern Be it known that I, ISAIAH B. LIBBEY, a citizen of the United States, residing at Charlottesville, in the county of Albemarle and State of Virginia, have invented new ,I and useful Improvements in Unloading Devices, of which the following is a specification.

y This invention relates to unloading devices, theprimary object of the same being to provide simple and effective means whereby coal oi the like may be delivered from one vessel to another vessel.-

With the above object in view the invention resides in the novel construction of elements and their arrangementI in opera tive-,combination as will hereinafter be fully described and claimed.

In the drawings, accompanying this specification, Figure 1 is a side elevation of theapparatus inapplied position upon a vessel, parts ofthe apparatus, as well as the vessel being iny section, the conveyer leg 6 being removed. Fig. 2 is a longitudinal sectional view taken approximately on the line 2 2 of Figi. Fig is an enlarged detail elevation, approximately on the line 3 3 of Fig. 2, looking toward the direction of the arrows, a portion/of the vessel, being shown in sec-tion and the bucket conveyer being removed. Fig. 4 is a t-ransverse sectional viewltaken upon `the line 4 4 of Fig. l. Fig. 5 is a detail sectional view taken approximately upon the line 5 5 of Fig. lV and illustrating the spline or key carried by the beveled toothed wheel 35 engaging withinthe longitudinal channel provided upon the shaft 36, whereby the said shaft is allowed to travel longitudinally7 through the bore ofthe said toothed wheel.

l Before proceeding with the description of the details of the apparatus, it may be here stated that while the said apparatus ,will be alluded to in connection with a collier" or other vessel, the said apparatus is not to be restricted as applicable only to a collier or vessel, as the said apparatus mayv be employed with equal success upon any suitable support. n

In the drawings, the numeral l desiglnates a collier within the hold of which mayv be arranged a suitable screw conveyor 3, the latter being provided with a suitable casing- 4. The casing 4 may have an open top, the latter being fully 01" partially closed through the medium of removable slats 5. Any suitable mechanism may be employed for operating the conveyor, the same not forming a part of the present invention.

The coiiveyer screw 2 has its casing 4 communicating with a bucket coiiveyer leg 6, the said leg being provided with suitable rollers 'K over which passes an endless belt 8 carrying the buckets 9. The. leg 6 extends above tlie deck of the collier 1 and is provided with a. suitable mouth which overlies the hopper 18 of my improved apparatus. The! buckets 9 may be operated in any desired manner, the said buckets las well as the leg G therefor being of the con- `ventional forni and being merely illustrated as a means whereby, when taken in connection with the screw 3, the coal or other material may be raised from the hold of the vessel and delivered to the hopper 18.

The hopper 1S is of a tapering contour and is centrally provided with' an outlet mouth 1.9.

The numeral 24 designates a hollow meniber which is preferably coneshaped and which may be connected to the hopper in any suitable or desired manner. The hollow member 24 surrounds the mouth`19 of the hopper 18, and the lower and reduced portion of the said member 24 is provided with an outwardly extending annular flange 25.

The numeral 27 designates a tubular member which has itsI upper extremity formed with a substantially cross-sectionally L-shaped annular flange or head, the same being designated by the numeral 26 and adapted to receive the flange 25 of the hollow member 24. The flange 25 is retained upon its seat through the medium of 'a suitable disk or ring 26 which overlies the said flange and which is connected with the off-set portion of the top of the L-shaped head provided for the tubular member 27. The deck of the vessel 1 is provided with an elongated opening through which the tubular member extends, and the lower portion of the said tubular lmember is preferably closed, through the medium' of a suitable cap, as illustrated in Figs. l and 2 of the drawings. The s'aid tubular member, adjacent its closed end is provided with oppositely arranged trunnions 27, the latter adapted to be received within bearingsA provided upon suitable standards 28 and 29,

outlet mouth, while the opposite end of the said casing is preferably closed/to provide a vbearing for one end of the shaft or trunnion of the saidspiral 21, and .connected with this end of the shaft is a toothed wheel 40, and whereby the said spiral 21 is re volved in a manner Awhich will hereinafter be fully set forth. Thevtop of the outletconveyer easing is provided with a plurality of spaced openings,'and surrounding the .edges ofthe casing provided by the said openings are crosssectionally L-shaped members, forming ways 23 for sliding doors 22; Any one of these doors is adapted to be slid wit-hinits waysto uncover with respective openings in the conveyer casing when'the said casing is moved through the openings provided by the hollow 4member 24, so that material may be delivered Within the conveyer casing through the mouth 19 ofthe hopper 18. The manner in which the said casing is moved Will pres-- ently be set forth. The casing 20' may be provided with longitudinally extending re Vinforeing plates 75, the same being arranged upon both the top and bottom of the said casing, and the casing is further provided upon its opposite sides with longitudinally extending combined' brace and supportingV plates 76. The plates 7 6 are preferably. constructed of L-irons, and the said plates rest upon bearing brackets 7 8 arranged within the hollow member 24, as clearly illustrated in Fig. 2 of the "drawings The casing 20, adjacent its outlet mouth is provided with a suitable eye 79, the said eye adapted to receive a suspending cable 80, the free end of which' latter may be connected with a boom or similar device.

Secured upon the ing 2O and terminating at a suitable distance away from the outlet mouth thereof, is a longitudinally extending rack bar 41, the -teeth Vof which bein engaged by a toothed wheel 43 provide upon a suitable shaft 42 which is arranged transversely of and mounted in bearings in the hollow coneshaped member 24. The shaft 42 has one of its ends extending a suitable distance beyond the said hollow member 24, and this extending portion is off-set orotherwise provided with a handle 44,whe'reby the toothed wheel may be vrotated to slide the casing 20 either toward or away from the side or end of the vessel or support 1.

The numerals 37 and 3S designate bearunder face of the cas-r ings carried bysuitable brackets, the same being arranged adjacent the ends of the rack bar 41, and the'said bearings are adaptedv to receive a shaft 36. This shaft 36 is preferably arranged directly below the rack bar 41. The inner .and lower closed portion lor wall of the hollow member 24 Ais provided with a. suitable bracket 81,- the said bracket having its vertical arm provided with an opening through which the shaft 36 extends, 7 5 and arranged upon the said shaft 36 and mounted for rotation u on the bracket 81 in any desired manner, is a'beveled toothed wheel 35. The shaft 36 is provided with a longitudinally extending groove or channel 82, and the toothed wheel 35 has its bore provided witha spline or feather 42 which engages within the saidgroove 82, and whereby the shaft 36 may be free to move j through the bore of the said beveled toothed g5 wheel 35 when the casing 2O is moved longitudinally through the medium of its rack bar and the toothed wheel 43. Meshing with the toothed wheel 35 is la similar beveled toothed wheel 34 carried upon one end of a 90 shaft 35 which is centrally arranged within thetubular member 27 and which finds bearings in openings provided -within the bottom of the hollow member 24 as well as through one arm of the bracket 8 1 and through an 9,5 opening provided in the removable cap of the said tubular member 27. The opposite end of this shaft 33, which projects through thel cap of the tubular member 27 is also provided-with a beveled toothed gear, 32, the same meshing with a similar toothed wheel 31 which is proi ided upon a shaft 30 having a bearing in the standard 28, and connected with any suitable source of power,

Secured to the hollow member 24 andar- 105 the disk 26 is a ring having its upper face provided with teeth, and these teeth are4 adapted to be engaged by a toothed wheel carried upon a shaft 50 which is mounted 110 within the bearing provided by a bracket The shaftI 50 is bent to provide an off-set handle 51, and by this arrangement it will be noted that means are provided whereby ranged directly above member 54, the same the hopper, hollow member 24, casing 20, as.

well as the parts carried thereby may be rotated or revolved around the tubular mem-` ber 27.

Arranged upon the top or deck of the Vcollier 1 adjacent the longitudinal walls-120 formed by the opening'. through which the tubular member 27- passes, are a pair of arcuate toothed bars 45, the said bars being positioned adjacent the opposite sides of the said tubular member 27. These toothed racks 45 are struck-at anaic from the axial center of the shaft 30, and the teeth of the said racks are adapted to be engaged by toothed wheels 48 providedupon a shaft 46 which extends through suitable openings 1 30 v remainder of the device forming bearings in the -as to raise or lower the 20 as desired. v

The shaft 36 extends a suitable distance l through itsbearings 38 and `the said extendv the'splral conveyor ,21.

-ed portion is provided with a toothed wheel 39, the said wheel meshing with tooth Wheel 40 provided up v,n the trunnion or sha-ft'of By this arrangement it will benoted that when thev ower shaft is. in motion, the said spira v oonveyer -21 will be rotated within its casing,-

through the medium -of the tooth wheels 34, 35, 39, and 4o.

The L-shaped top or ring 26 ofthe tubuw lar member 27 is provided with a spring pressed pawl 83, the same'adapted to engage between the teeth of the wheel 43 to secure l the apparatus in a proper position with the what I claim is:

arcuate toothed bars or racks 4:5.
