COAL HANDLING APPARATUS.

To all whom it may concern Be it known that l, FINLY F. JOSEPH, gjc itlzen of the United States, residing at hlcago, 1n the State of Illinois, have inreceiving hoppertoan elevated receptacle.

I have illustrated the inventionin a preferred form in the accompanying drawings.

in which-- Figure 1 is a diagrammatic view and partial section, showing the arrangement of ti e bucket carrier with relation to a coal chute. Fig. 2 is a partial side elevation of the bucket and supports'looking to the right, near the top ofFig. 1. Fig. 3 is a top plan view of the outer trolley end of the carrier and guideway. Fig. 4 is asection show ing the bucket and gate in position at the mouth of the coal chute, the section being on the line (IV)--(IV) in Fig. 5, while .Fig. 5 is a vertical section at right angles to that of Fig. 4, along the line (V)-(V) in Fig. 4:, showing the supports for the gate of the coal chute. Fig. 6 is a plan view of the bucket and gate in the position shown in Fig. 4.

Cylindrical gates for controlling thedischarge from a receiving hopper have been used heretofore, but they have either been arranged to act as a double gate, orhave been used in connection with a second gate,

with the result that the co..l bucket must be landed at a position below the mouth of the chute, while the loading his been; dependent upon extra measuring devices. my device I use the coal bucket itself as the second gate and arrange for finally dumping the charge of coal to the bottom of the bucket only after the full charge has been received. a

While the use of cables and guideways for i have been disadvantages in theswinging of the bucket 'and'in the passage of the same around curves I employ atrolley supwhich being equipped for the :bucket in the guideways. port for the cable, with the socket supports moves with the bucket itself at the proper time and renders the action more certain,

l prevents idle swinging of thebucket, and

secures other advantages. to appear here'- I i l after.

As shown in the accompanying drawings. I prov de near the mouth 7 of the hopper, an incllned landing platform 8 which may or may not be provided with a counter-.

weighted truck 9 thereon, and which is used to receive the coal bucket 10 and place it ready for filling. That is, the bucket in descending lands upon the truck 9 and then moves back against the abutment? directly under. the end of the coal chute 7, avoiding any spill of material. As shown more clearly in Figs. 4: and 5, it takes position under the cylindrical gate 11, 13, and inclosing part of it, the bucket sides entering between the trunnion supports 12, 12 of the gate and the gate itself. The short shafts 19. have loosely mounted upon them, these supporting arms 12 which carry the gate closing the chute 7. This cylindrical gate has a. depending skirt 13 which normally extends to a point. about flush with the bottom of the chute as shown in Figs. 1 and 4, but it is of size to extend within the bucket 10 as shown in dotted lines in Fig. 4, in the act of opening, the supporting arms remaining outside the bucket as shown in Fig."5.

The cylindrical wall of. the gatell has an opening 14 normally above theposition of the coal in the chute; and it will be observed that when the gate is revolved downward so that the skirt 13 extends into the bucket as shown in Fig. 1, the'opening 1 1 will register with the chute and allow the f coal to flow in until the top part of the bucket is filled, the charge being held in suspended position by'the skirt 13-. The coal chute is then closed by the rising of the gate with its ing from the bucket, simultaneously dumps a charge in the bottom thereof.

Arranged near the landing platform 8, l provide guideways 15 which engage rollers on the sides of the bucket, while atanother point on each side of the bucket I attach a hoisting cable 17, running over the' skirt 13, which, by withdrawhorizontal travel in g'uideways 26, and thence over any other convenient sheaves, as

I 27, to thehoisting engine. In operation, the

bucket 'isihoisted; between the pair of sheaves -l8'and guided by the guideway 15, until the f pins QSaon-the bucket strike the forked arms 29 ofthe trolley 20, whereupon thetrolley will be ca-rried along with the cable and bucket, the wheels 21 and 23 riding in the track 24. At the proper point I place atripping bar which engages the tailen'd of the spring or counterweight catch 31, which,

retains the dumping gate 32 of the bucket 10, as will be evident.

' This cable 34 is supportedat this point on pulleys 35 and36 and continues over pulleys 37 and 38 and is attached to the gate lllby pin 39 and thence proceeds over pulleys 40, 41 and 42 back to the movable block 25 sup- .porting'the main cable sheave 25. As soon as a. pull is exerted onthe loaded bucket 11 therefore, tension is exerted on the cable34 by movement of block 25, so that the pin 39 on the gate ispulled upward and the gate is closed. On the. other hand when the ten- .sion on the cable 17 is. relieved by the landing-of the bucket against the-wall 7*, the counterweight 33 will pull on the cable 34 by block 25*, and this will throw down the closing gate 11 into the bucket, causing the opening 14 therein to register with the coal chute, admitting the charge to load the bucket.

It will be observed that by the above described mechanism, the operation is automatic, depending on the handling of the receiving the charge.

hoisting engine alone. bucket descends it lands in place directly at the mouth of the chute and by the act of landing causes a slack in the cable 34 allowing amovement which causes the gate to open and extend into the bucket, while the bucket meantime'acts as a stop gate upon Upon exerting tenstion on the hoisting cable, the action isto close the gate by lifting thedepending sk'irt out ofthe bucket, whicht-hereupon deposits the load on the bottom of the bucket. When the loaded bucket arrives at the lower stationary position of the trolley 20, the bucketitself carries the-trolley, by pin 28, which, together with the guide 15, gives a firm and accurate support for the weight of the bucket as soon as it passes out of the direct vertical support of the hoisting cable. It is of course understood that the trolley track 24 extends to whatever position it is desired \Vhen the emptyto dump the load. The useiof this trolley together with the guide 15 prevents-any swingingof the bucket either when loaded or empty and'the use of the counterweight 33 allows for taking-up any overwind with out disturbing the relationof the parts I regard the use of the perforated gate with a skirt extending into the bucket during the loading, and the use of a movable.

head shaft and sheaves, and'the use of the traveling trolley, andthe use of an inclined landing invention.

' The various advantages of theapp'aratus will readily occur to those familiar with theart. 7

Having'thus described my invention and illustrated its use, WhatI claim is the following: 1 v,
