CONVEYING MECHANISM FOR COKE-DRAWING MACHINES,

SPECIFICATION formingpart of Letters Patent N 0. 728,168, dated May 12, 1903.

Application filed August 14, 1902- Serial No. 119,620. (No model.)

To alt whom it may concern:

Be it known that 1, JOHN A. HEBB, a citizen of the United States, residing at Uniontown, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Conveying Mechanism for Coke-Drawin g Machines, of which the following is a specification, reference being had therein to the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan view of my improved coke drawing and conveying machine, showing it in position in front of an open door,- portions of the traveling'conveyer and-"thebeam being broken away. Fig. 2 is a detail cross-sectional view on the line II II of Fig.1. Fig. 3 is a view in side elevation of the apparatus. Fig. 4 is a longitudinal vertical section through the delivery-conveyer, indicated by the line IV IV of Fig. 1. Fig. 5 is a simi lar view indicated by the line V V of Fig. 1, showing the receiving-conveyor in elevation. Fig. 6 is a plan view showing the driving means for both conveyors.

My invention relates to apparatus for drawing coke from the oven and for conveying it away therefrom for delivery into cars for transportation or upon the yard.

The apparatus consists generally of a moving structure adapted to travel forward and back in front of the ovens, provided with a turn-table carrying a reciprocating beam adapted to be extended into and withdrawn from the oven to empty the contents therefrom.

The present application refers more particularly to the conveying mechanism which receives the coke fromthe oven-door and conveys it away therefrom at whatever position the machine may assume and finally delivers it as indicated.

Referring now to the drawings, A represents the framework of a portable carriage carrying a turn-table B,upon which are mounted the various manipulative portions of the machine.

Mounted in suitable bearings is a main shaft 4, driven at one end by a suitable prime 6, which bevel-wheelin turn meshes into the :bevel-wheel 11 on shaft'fi, so that when main "shaft 4 is driven'shaft 5 will also be continuously driven in the direction indicated by the arrows. From these main shafts all of thevarious operations ofthe machine are transmitted, the conveyors being driven. bysprocketwheels mounted on the ends of shafts 4and '5, respectively, as shall be hereinafter de- :1 I 27 is the reciprocating beam, adapted to be extended into and withdrawn from the oven and provided at its forward end with a rakehead' 3l,'adapted to engage a portion of the coke in the oven and to draw it out through the door and to discharge -it-upon the receiving-conveyer, the beam being manipulated.

by suitable gearing fully described and shown in other contemporaneously filed applications bearing the serial numbers 119,617, 119,618, and,119,6l9. i

' At'the side of the machine adjacent'to the oven is located theconveyer 0, consisting of a series of slats 81, forming an end less apron, secured upon and carried by sprocket-chains 84: The chains are carried upon sprocketwheels 82 and 83, mounted on the head-shaft -85-and tail-shaft 86, respectively, carried-in bearings on longitudinalme'mbers87 or other suitable framework rigidly supportedv from framework A. The head-shaft 85 is driven through sprocket-wheel 88 on shaft 5 and chain 89, passing around driven sprocketwheel 90, by which 'continuousmovement' is imparted to the conveyer during the rotation of the counter-shaft 5. 4

Arranged at right angles along one end of the apparatus is the conveyor D, which is of any suitable length adapted to the width of the yard or the distance to which it is desired to convey the coke, and this conveyor is generally similar to the one just described, the

slats, however, being somewhat separated to permit of the escape of the dust or small particles of coke. The slats 81 are mounted upon sprocket-chains Sat, passing around sprocketwheels carried by head-shaft 91 and tail-shaft 92, the head-shaft being mounted in bearings rigidly supported from the framework of the machine.

The tail-shaft 92 is mounted in hearings in the outer end of the supporting-framework 97, which may be rigidly carried upon suitable supporting mechanism extending outwardly from the machine, which is preferably pivoted to said supporting-framework at 98 adjacent to the head-shaft, thereby permitting the inclination of the conveyer to be varied as desired. The pivotal bearing 98 is adjacent to the driving sprocket-wheel 94, so that variations in the height of the conveyer will not affect the tension of the drivingsprocket-chain. The conveyer-D is driven by sprocket-wheel 94 on shaft t and chain 95, passing around a driven sprocket-wheel 96, mounted on tail-shaft 92, the speed of the conveyer, as is also the case with the conveyer 0, being regulated by the relative proportions of the driving and driven sprocketwheels.

For the purpose of preventing clogging of the apparatus the speed of conveyer D is somewhat greater than that of conveyer 0, so that the coke discharged on conveyer D will always be carried away somewhat faster than it is received.

Conveyer D is supported at its outer end or at any intervening position by any suitable framework, either extending outwardly from the main frame or downwardly to the ground from the conveyer in the manner of a prop; but as various means may be utilized for this purpose,thesupportingdevices are not necessarily specifically shown or described.

As shown by the drawings, the general level of the first conveyer C is but slightly below the level of the oven-floor, but is considerably higher than the inner end of the conveyer D, and the coke from conveyer O is discharged upon an inclined apron or floor 99, extending downwardly from its delivery end to the inner end of the conveyer D, while on the front and also the back of conveyer O are sloping pans or floors 100, of sheet metal, adapted to receive the overflow and to return it to the conveyer. These pans connect with a surrounding hopper 101, having sloping sides adapted to deliver coke from all directions upon the traveling slats, and for the full length of the conveyor D it is provided with a pan 102, having upwardly-extending sides 103, upon which pan and between which sides travels the sprocket-chain and slats of the conveyer.

For the purpose of providing a quiet hearing for the slats the floor of said pan may be provided with longitudinal strips of wood 104,

upon which the chains or slats are adapted to travel.

At any position in the length of conveyer D, but preferably near the front end, one or more openings are made in the floor, and below such openings is located the laterally-inclined dust-chute 105, adapted to receive the dust,which will fall through the slats and be drawn forward to such position at which it will fall by gravity and will discharge at either side of the conveyer.

As will be understood, both conveyers 0perate continuously during the operation of the machine, and the handling of the coke is done automatically from the time it is drawn to them from the oven.
