To @ZZ whom, t muy.; concer-7b.

Be it known that I, GEORGE E. TITCOMB, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvementin Unloading Apparatus, of

whichthe following is a full, clear, and exactv description, reference being had to the accompanying drawings.

The invention relates to unloading apparatus which is especially adapted for transferring ore from the holds of vessels to cars or a stock-pile. 1

The object of the invention is to reduce both the time occupied and the cost involved in unloading ore-boats, and these results are attained in the manner and by the means substantially as hereinafter described.

The invention consists in the combination of parts as shown and described, and deiinitely set forth in the claims.

In the drawings, Figure 1 is a side elevation of the apparatus in position to unload an ore-boat, which is shown in vertical section. Fig. 2 is a plan view of-"the same apparatus. view through the wheel-truck and the member G, which carries the bucket-track and other mechanism which will be described. Fig. 4L isa top plan view of this member. Fig.

5 isa sectional plan View on line 5 5 of Fig.. 3. Fig. 6 is a sectional plan on line 6 6 ofv Fig. 3. Fig. 7 is a plan view of the bucket,

and Fig. 8 is a side elevation of the bucket.

The apparatus includes in its most approved form, as shown, a supporting-frame A, which is to be located on the dock. It may be of any suitable construction; but preferablyr it is movable along tracks on the dock and is of skeleton form, so that carsto receive the ore may pass beneath it. This frame supports a horizontal skeleton platform B, which may be adjusted vertically, preferably by means of four screws a2 CL2 at its corners. An extension skeleton platform B is hinged at its rear edge to the front edge of this platform B and is adapted when the apparatusis in operative position to rest upon the deck of the boat Y and over the hatchway y through which the boat is being unloaded. When the apparatus is not in use, this extension-platform may be swung on its Fig. 3 is a central vertical sectionalalso, may a wheel-truck E, which supports the unloading mechanism. The wheel-truck is provided with an electric motor e4, by

whicl1,through suitable intermediate mechanism, it. is propelled along the tracks b4. This wheel-truck is provided with two concentric circular tracks c e', and a circular wheel-truck H rides upon the inner track e, and a ring J is mounted upon the wheels h of this truck H, which ring has gear-teethj on its outer periphery. A pinion 7c engages with these gear-teeth, and this pinion is attached to a shaft K, suitably mounted on the truck E. A bevel-gear 7c',

secured to this shaft, meshes with a bevelgear c6 on the shaft c7 of an electric motor e8,

carried by the truck E. Thus by the operation of this motor this ring J may be turned in either direction. A vertically movable member G passes through this ring J and has vertical grooves g g, formed by angle-irons g g', secured toits sides. Tongues j2, fast to the ring J, ent-er these grooves and, while permitting Vertical movement of this member relative to the ring, prevent any relative rotation of the said two parts. This member G is of tubular character, although it is of skeleton formation, built up of iron bars and beams bolted or riveted together. nal bucket tracks or guides g3, placed at diametrically opposite points, which tracks eX- tend vertically downward and then are curved around into horizontal position, the horizontal parts g4 ofA said tracks being fast to and It has two intersupported by a horizontal extension g5 of the IOO may be turned upon said track e' to bring any of said doors into proper relation to the dumpcar M. This vertical member has mounted on its upper end a motor P, preferably an electric motor, and a plurality of drums Q Q, R R, R R', and S, upon which cables may be wound and which may be driven by said motor, intermediate mechanisms, and clutches.

Two cables U U', which are attached, respectivel y, to diametrically opposite sides of the ring J, pass down under sheaves Q6, mounted on the vertically-movable member G near its low-er end,and then up over sheaves S S2 to the winding-drum S on the top of said member. These cables are wound up or unwound, as the case may be, with the result of lifting or lowering said movable member G to bring its lower end to the proper elevation relative to the ore in the hold.

The bucket C, as shown, for elevating the material is of the clam-shell Variety. The two shells c c' are rotatably4 mounted on a horizontal bar V, which is a rigid part of the bucket-supporting frame. This frame consists of a plurality of triangular plates v', which are fastened togetherand held in proper relation by said baro and by three other bars c2 fus e4, located at the corners of said plates. A horizontal shaft F, parallel with said bars, is mounted in this frame in about the middle of said triangular plates. On the projecting ends of this shaft are loosely mounted friction-rollers f f which fit in the bucket-tracks g3, carried by said member G. Secured to this shaft between these friction-rollers and the bucket-shells are two sheavesfz f3. To each end of these sheaves the cables r 0" are fastened and wound in opposite directions, and the upper ends of said cable are connected, respectively, to the winding-drums R R. Vhen the four drumsR R R' R' are simultaneously turned in one direction, the bucket and its frame may be raised through the tubular member G, being guided by the buckettracks g3.

Two cables q q are attached, respectively, to .rings q2, which loosely embrace the shaft F, which cables pass around sheaves g8 at the outer end of the horizontal extension g of the member G, then under sheaves g, placed near the angle between said extension and the vertical member, and thence up to winding-drums Q Q at the top of the member.

The shells of the bucket are opened and closed by the following mechanism: Chains attached to the top edge of said bucket-shells pass up and over idler-pulleys t', mounted on the upper bar c3, and thence down to sheaves f4, attached to said shaft. The chainslf t, coming from both sides of the bucket, are attached to the corresponding side of said sheaves f4. It is therefore apparent that by turning said shaft F in one direction these chains are wound up and the bucket-shells are compelled to swing away from each other. In other words, the bucket is opened. Other chains 15H2 are likewise attached to the top edge of said bucket-shells and pass under idlerpulleys t3 t3, loosely mounted on the two bars e2 fu", and thence up to other sheaves f5, attached to said shaft F. These are the closing-chains, and they are attached to corresponding sides of their respective sheaves f5. By turning said shaft F so as to wind up chains t2 the other chainstare unwonnd, and vice versa.

It will be observed that in the hoisting operation the bucket alone moves up and down. The vertically-movable member is, strictly speaking,a vertically-ad j ustable member, because it is not moved except for the purpose of adjusting its position relative to the orepile in the boat, and it may be moved up or down through the ring J, or the said ring and said member may be turned to eect this result. When the apparatus is not in use, the said member is drawn up so that its lower end is above the platform on which the truck E is supported. Said truck is moved inward onto the platform B and the platform is swung up into the position indicated by the dotted lines in Fig. l.

When a boat to be unloaded ties up to the dock, the frame A is moved along the docktracks to the proper position, the platform B is lowered so that it rests upon the deck of the boat, but over one of the hatchways, the truck E is moved out onto the platform B', and the member G is lowered through the hatchway and turned, if necessary, to bring its lower end into proper relation with the ore-pile in the hold of the boat. The bucket is during these movements in its elevated position and is preferably open, as shown in Fig. 3. The bucket is lowered by unwinding equally the cables fr r fr" r', and at the same time the cables q t] are wound up. Thebucket is drawn by these cables around the curve in the buckettrack and along the horizontal part thereof up to the ore. Then without loosening up on the cables q the cables 1 r are taken in and the cables fr r slacked up, which results through the described mechanism in closing the bucket-shells over a load of the ore. The cables fr r are now wound up equally, and thereby the bucket is raised, the cables q being unwonnd to permit such movement. When the bucket is near the top of its movement, its frame strikes a horizontal beam W and lifts it. This beam is suitably guided, and its ends are attached by links w w to arms 0, which extend outward from two deflecting-plates O O,which are hinged to said member and are adapted to swing inward beneath the bucket until their inner edges come together, at which time both plates are inclined outward, as shown in Fig. 3. The lifting of the bar acts through said links to swing said plates into the position shown in Fig. 3. The bucket is then opened by taking in the cables and slacking up on the cables. The load falls onto these deflecting-plates and slides outward and then down into the hopper N. The guide-boxes T T, consisting of inclined plates above the plates IOO IIO

O and with vertical end plates or lianges t, prevent the ore falling out beyond the hopper. The plates O are wide enough and steep enough so that the ore will not pass over the side edges before it comes under the guiding infiuenceoftheflangest. Themasrststated, the bucket is lowered by equally unwinding the cables r r. The downward movement of the bucket permits the bar W to descend, thereby, through the links, dac., swinging the deiiecting-plates O O into vertical position, as shown by dotted lines in Fig. 3, which permits the bucket to descend. The ore in the hopperI is allowed to fall, as desired, through the doors into the dump-car, by which it is carried inward over the cars and dumped. The hopper N may be turned to bring any door therein in proper relation to the said dump-car.
