To all whom it may concern.-

Be it known that we, SAMUEL T. VVELLMAN, CHARLES ILWELLMANJOHN W. SEAvER,and THOMAS R. MORGAN, citizens of the United States, and residents of Cleveland, Ohio, have invented certain Improvements in Coke-Loading Apparatus, of which the following is a specification.

The object of our invention is to provide means whereby hot coke from a coke-oven'or a series of ovens may be quenched and loaded in cars with a minimum expenditure of human labor, the apparatus being also of such character that large quantities of coke can be handled in the shortest possible time and can be delivered into cars on two or more parallel tracks instead of the delivery being limited to a single line of cars, as in other coke-loading machines with which we are familiar.

In the accompanying drawings, Figure 1 represents in side elevation sufficient of a coke-loading plant to illustrate our invention. Fig. 2 is a similar view with some of the parts in a different position. Fig. 3 is an end view of one of the loading-pans and part of the trolley mechanism for handling the same; and Fig. 4 is a View on a reduced scale, showing a modification of part of the invention;

In Fig. l of the drawings,l represents part.

of one of a row of coke-ovens, and 2 a cantaliver gauntree crane, having its legs running upon rails parallel with the row of coke-ovens, this crane spanning two or more railwaytracks, upon which are intended to be run the cars to be filled with the coke. The crane has a traveling trolley 3 for handling any one of a series of pans 4., suitablysupported upon.

walls 5 and 6 in front of the row of. ovens, each of these pans serving both as a quenching and loading pan, being open at the inner end or end next the oven, so as to receive the charge of hot coke pushed therefrom and which after being deposited in the pan can be quenched by water directed upon it by means of attendants on the platform in front of the row of ovens, the quenching-water discharging into the channel 7 between the walls 5 and 6, from which it escapes through a suitable drain or sewer pipe. The pans 4 may be of any suitable length, and-the trolley 3 is provided with any desired number of depending hangers, from which the pan may be suspended, there being by preference four of these hangers, one for each corner of the pan, as will be clearly seen by reference to Figs. 1 and 3. that end of the pan farthest from'the ovens the front end and the open end of the pan,which is nearest to the ovens, the rear end. The trolley 3 is preferably provided with a transversely-rigid depending hanger 9 for each of the rear corners of the pan, as shown in Fig. 3, this hanger having at its lower end a hook 10 for engagement with ahook, eye, loop, or equivalent structure ll'at said rear corner of the pan. A locking-bolt12, controlled in its movement by a solenoidor other electromagnet 13 on the hanger 9, engages with the eye or other attachment on the pan after-the same has been caught by the hook and prevents any accidental disengagement of the two, as shown clearly in Fig. 2, where the bolt is in its lower or looking position, as it closes the open side of the hook and prevents the same from being disengaged from the eye on the pan. The eyes or other lifting attachments 14 at the front corners of the pan are engaged by swinging books 15, carried by suitable hoisting-tackle 23,depending from ahoisting-drum 16 on the trolley 3, as shown in Figs. 1 and 2. The depending portions of the hoistingtackle are inclosed in a telescopic incasement 17, the lower section-of which is provided with fulcrum-bearings for the swinging hook, as shown, and to which the hoisting-tackle is attached, by which construction said hoisting-tackle is protected from being injured by the steam' and hot gases arising from the coke and at the same time is held ina rigid vertical position, so that no swinging or swaying of the loaded pan is possible after the same has been picked up by the trolley, thus providing transversely-rigid hangers and lifting devices, to which the pan is suspended at its four corners. A solenoid or other electromagnet 19 on the telescopic incasement of For convenience we will denominate portion of the hook 15, thus holding the same in positive engagement with the eye on the pan when the solenoid is energized in the manner well understood by those skilled in the art.

It will be understood that the crane is provided with the usual electric or other motive power apparatus for moving the same, for traversing the trolley, and for operating the hoisting mechanism, such motive power ap paratus, as well as the electromagnets 13 and 19, beingunder control ofan attendant in the cab 20 of the crane.

The operation of the apparatus is as follows: The pan resting upon its supports in the inclined position, as shown in Fig. 1, is loaded with hot coke, pushed into the same from the ovens, and after said'colre has been properly quenched the crane is moved into line with the pan and the trolley3 is run forward on the crane until its hooks 10 and 15 have engaged with their corresponding fastenings on the pan, whereupon the connections are locked, as shown in Fig. 2, by means of the magnetic devices described, and the front end of the pan is then lifted by operating the hoisting mechanism of the trolley until the pan has been raised clear of its fixed supports and assumes a substantially horizontal position. The crane and its trolley are then operated until the rear end of the pan occupies the proper relation to a car into which the contents of the pan is to be loaded, whereupon there is a further lift of the front end of the pan, so as to tilt the same and cause its contents to be discharged into the car, as shown by dotted lines in Fig. 2, after which the operations are reversed and the pan is restored to its position on the fixed supports 5 and 6 preparatory to receiving another load. As the entire handling of both the loaded and empty pans is thus effected by a single attendant, the amount of human labor employed is reduced to a minimum, while the use of a number of independent pans for each handling apparatus and the provision for loading oars upon two or more tracks insures the expeditious handling of large masses of coke in the least possible'time, and consequently reduces the expense of loading to the lowest possible figure.

In Fig. 4. we have illustrated a modified embodiment of our invention in which a trolleycarrying bridge 21 travels upon runways on

elevated supports

22 and 23, one of said elevated support-s running along the end of the row of ovens l and the other being outside of the tracks which receive the cars to be loaded.

If desired, hoistingtackle may be employed for the rear portion of the pan as well as for the front portion of the same; but the use of a rigid support for said rear portion of the pan is preferred because of its greater simplicity and convenience.

Having thus described our invention, we claim and desire to secure by Letters Patent-- 1. The combination with a crane structure, of a trolley adapted to run thereon, depending and transversely-rigid lifting and supporting devices carried by said trolley, a loading-pan, and supports to hold the pan in position under the crane structure, so that it can be engaged and lifted by the supporting and lifting devices, substantially as do scribed.

2. The combination of a traveling crane, a trolley thereon having transversely-rigid de pending supporting and lifting devices, a loading-pan, supporting means for fixedly supporting the pan in an inclined position under the lifting devices, said lifting devices adapted to lift the pan from its support and tilt it so as to dump its contents, substantially as described.

3. The combination of a crane with a trolley having trans versely-rigid depending hangers provided with means for engaging apan, and means for operating one set of said hangers so as to raise the pan from its support, substantially as specified.

4. The combination of a crane with a trolley having transversely-rigid dependinghangers provided with means for engaging a pan, and means for operating one set of said hangers so as to raise the pan from its support, and then tilt the same, substantially as specified.

5. The combination of a traveling crane with a trolley having depending hangers provided with means for engaging a pan, and electrically-controlled locking devices for said engaging means, substantially as specified.

6. The combination of a traveling crane, with a trolley having depending hangers for engaging a pan, the hangers for one end of ICC the pan being rigid and those for the other SAMUEL T. WELLMAN. CHARLES H. WELLMAN. JOHN XV. SEAVER. THOMAS R. MORGAN.
