ELECTRICAL APPARATUS FOR SEPARATINGCOKE FROM CINDERS, ac.

SPECIFICATION forming part of Letters Patent No. 781,437, dated January 31, 1905.

' I v Applicationfiled April 13, 1904. Serial No. 202,957.

To aZZ whom, it may concern Be it known that I, HENRI LELARGE, of 808 Rue de' Renory, Kinkempois, Liege, Belgium, have invented a new and useful Improved Electrical Apparatus for' Separating'Coke from Cinders and other Substances, of which the following is a full, clear, and exact description.

This invention relates to the separation of coke from cinders and. other substances such as stones, slate, and the likefrequently embodied in coal. I

The object of'the invention'is to provide mechanism which Will quickly and efliciently effect the separation by means of electricity.

and deposit the assorted coke and other substances into respective receptacles.

For a detailed description of my invention 1 reference is to be had to the accompanying drawings, wherein- Y Figure is a side'e levation, partly in section, of my improved apparatus. Fig. 2 is a plan illustrating parts of the mechanism shown in Fig. 3 is a detail view illustrating parts shown in Figs. 1 and 2 drawn to a larger scale. anism drawn to a larger scale.

A refers to a rotary sifter which assorts the cinders, &c., and deposits them upon the in-' clined plate B, from whence they fall onto they I inclined plate 0.

A drum D is rotatably carried by a'suitably-supported shaft Xand has secured toits ends ratchet or toothed wheels E. On the circumferential surface of the drumare radially and longitudinally arranged angle-irons F. The longitudinal channels formed by the irons F are transversely divided by a series of plates H, which are suitably supported by a fixture, as A, and the end ones extend downwardly below the drum. i

Pivotally mounted on the shaft X are two rockinglevers J, to which an oscillatory movement is'ir'nparted by wrist-pins U of crankdisks U on shafts X. The levers-J each carry a depending link I, connected to one end of a pivoted rock-bar I, to the other end of I which is pivoted the pawl I, which engages the teeth of the wheel E.

Fig. 4: illustrates the electrical mech-- depending rods Q, which are adjustably connected, by means ofa pivot Q and slot in the bar-rod, to the frame which carries 'electro magnets S. This frame is pivoted on a suitably-supported shaft Y and carries the arms S. .The shaftY has hinged to it, an armature T with the battery P, and the battery is connected by a wire T to any suitableparts of the drum D. I I

The operation of the apparatus is as follows: (Joke, cinders, &c., fall, as before mentioned,

from the sifter A to the chutes B and O and enter the spaces between the angle-irons F and are retained in even distribution along said spaces bythe plates H. By the rotation of the drum D the coke, cinders, &c., are carried around until they are brought into contact withthe metallic tongues K. During the rotation of the drum D, which receives anintermitt'ent motion from the pawls I and wheels E, the electromagnets are rockedabout the shaft Y by the rods Q and levers J. vWhen cinders and other matter which are not contact with the tonguesK, they simply pass to the chute G and fall into asuitable receptacle. VVhen', however, coke or other conductors of electricity are-brought into contact with one of the tongues K, an electrocircuit is made through the drum D, wire T, battery P, wire T,.-electromagnets S, and wire T Consequently the magnets become excited and attract and draw rearwardly the armature Z from beneath the projection L, thus permitting the plate or chute M to fall-into alinement with the chute G to receive the coke there- 'from and conduct it by gravity to a receptacle separate from that which receives the cin- 5 ductors of electricity are brought into conders. At each oscillation of the magnetframe the arm S replaces the chute M into approximated vertical though slightly-inclined position and if the current be broken 5 releases the armature Z and leaves it in position Where it is retained by the Weight Z to support the projection L and chute M.

Having noW particularly described and aseertained the nature of my said invention and in What manner the same is to be constructed and operated, Ideclare that What I claim is 1. An apparatus for separating coke from cinders and other substances, comprising a rotary drum having upon its surface channels or receptacles for receiving the material to be separated, a stationary chute for delivering material from said drum, a movable chute in proximity to said stationary chute, and automatic means for shifting said movable chute into position to deflect coke and 2 5 tary drum having upon its surface channels or receptacles for receiving the material to be separated, electrical conductors contiguous to said channels or receptacles, electromagnets electrically connected with said conductors, a

3 stationary chute for delivering material from said drum, a movable chute in proximity to said stationary chute, and means operable by said electromagnets for automatically shifting said movable chute into position to deflect coke and other electrically-00nductive substances from said stationary chute.

3. An apparatus for separating coke from cinders and other substances, comprising a rotary drum provided upon its surface with channels or receptacles for receiving the material to be separated, electrical conductors contiguous to said channels or receptacles, electromagnets electrically connected with said conductors, a stationary chute for delivering material from said drum, a gravity-positioned chute pivoted in proximity to said stationary chute for deflecting coke and other conductors of electricity from the same, and means operated by said electromagnets for automatically locking said gravity-positioned chute in inoperative position and for automatically unlocking the same.

In testimony that I claim the foregoing as my invention 1 have signed my name in presence of two subscribing witnesses.
