1.0.theinvention, such"`as will enal'ilefs'f'tliers 'skilled in the'art to which itappertains to make and use the same. i .invention relates to mechanism or apparatusby means of which coke ovens man be charged from one or both ends with .co to any required depth by a machine of To carry vm' v 4invention into practical effect I use a trayor chute o f a 'suitable 2li-length arranged at a height to `suit the depth of the required layer. of coal, and

` Vcarried on runner wheelswhich wouldrun on the floor of the oven,` or thetray or chute could be supported near the one end on a fixed support and be of sufficient strength to-caxry'xtself as acantaliver. This tray or ,chute isl run into the oven h hand or medhanically by certain mechanism which pushes the tray or chute forward at any required speed to the end of its stroke near @the farther end the coke oven, and then the chargi focal begins'. runA along the tray or chute a from the projector or charging machine, the 35 tray or chutel is slowly wit drawn from the oven, the speed of withdrawal being arranged by gearing in such, a manner that the tray or chute is withdrawn about as last as the charge of coal fills into the oven, and so that the tra or chute is completely withdrawn just'be ore the charging of the oven is completed.

The mechanism might be carried by a frame geared in a suitable wa to the rol ,lector mechanism or it mi ht c carrie on e. separate frame and be riven separatel Ybut at a suitable speed correspondlngwit .the speed of char ng.

The coal from t e projector machine will slide along the tray or chute and will fall oli the end, and the thickness of the layerwill he determined by the height at whichA the 1- holo stands in the oven. 4 It is not 'of a coke oven c commences. 'As soon as the necessary for the tray to be withdrawn continuously, butit may equally well be done by a step by step motion. Y

In order that this invention may be readily understood I will proceed to describe the same with reference to the accompanying drawings, in which l show the applica'- tion of my invention to a charging machine for coke ovens. A Figure v1 is an elevation of the-charging machine supported on Wheels which run along rails laid on the floor in front of the coke oven. Fig. 2 is a plan of the gearing for moving the traf; into and out of the oven." Fig. 3 is an elevation of the tray with the rails for supporting same, and the chains for connecimg the chute to the traveling gear. Fig. 4 is a detailed side elevation of the clutch shifting cam.

Referring to Fig. l a is thomann framework A arging machine supported on Wheels b which travel along rails c laid on the floor, d is the oven to be charged with coal b the machine,. and e is the tray along; wlli the coal would slide into the oven when being projected by the projector f, g is the motor for pro elling the machine along the rails. h 1s tie hanging frame or support in which the 4tray or chute is carried by means of rollers 'l and y' is the chain which is attached to the hack end of the tray or chute and to the drum c around the .guide pulleys l and m. n is a motor for 'drivlnv the projector f and the gearfor4 operating the tray or chute e by means of a belt drivingV on to theshaft o which in turn drives by a pair of spur wheels a shaft p.

In order that the tray or chute e may have two speeds of` traveling, fast when entering the oven and slow when returning, the shaft p is fitted with two drivers, the one for the orward Vstroke bein a spur pinion driving a spur Wheel which iseycd on the shaft w on which is also keyed another 4s ur wheel gearing with a spur wheel a: which the drum shaft u, the other drive for the slow return which is regulated to suitthe flow of the coal consists of a worm gearin' with a worm 'wheel on the shaftr on which is also keyed a bevel or miter wheel s'whih drives a corresponding wheel t running loose on the drum shaft u. The Wheels t andx which run loose on the shaft u are each fitted with a runs loose on clutch face between which is arranged a double clutch 'y slidlng on a square or feather keys on the shaft u. The clutch y is automatically vactuated by a revolving cam z on the face of which the clutch lever keeps contact aoy means of a coil spring. The cam z is driven by means of suitable gearing from the shaft u the gear being so arranged that at the en of each inward and outward stroke of the tray or chute e the clutch is thrown out of gear automatically.

A is a hopper or bunker for holding the coal andis fixed on theframe a. The hopper would be fitted with an agitator B to insure the coal falling into the feeder C which is of the screw type and which delivers the coal into the projector. `The agitator B and the feeder C would be driven by suitable gearing (not shown) from the motor 'n which drives the projector and there would be a suitable clutch (not s own) for throwing them into and out of gear by a hand lever arranged in a convenient position for the attendant.

In operation the hoplper A is first filled with coal from an over cad storage hop er or bunker or by an elevator or other suita le means, then the machine or charging apparatus is 'laced opposite -the oven Yto be charged. he projector is then set in motion running at its maximum speed and the tray or chute e is run into the oven d by means of the chains j and the gearing, the coal being then fedfby means of the feeder B into the projector f which in turn projects the coal along the tray e to the farthest end of the oven whereit stacksor piles up vto the level of the tray e, then the projector f commences to slow .down which may be accomplished in any suitable manner and the tray e starts on its return stroke, the slowing down of the projector f and the speed of the tra e being so regulated that a level bed of coa is insured the full lenglth of the oven when the charge is complete and the operation ma? then be repeated. The slowing down o the projector f may be accomlislied in several Ways. If the motor n is or a continuous current it would be arranged as a shunt motor with the field magnets regulated b meansof avrheostat in such a manner that t e speed of the motor could be increased'by adding resistance to the field circuit and so weakening The rheostat is of the ordinary type largely used for variable s eed motors. Ii' the motor is for vuse with three phase or alternating current it would run at a constant speed, and a variable speed of the projector lwould be attained by usin a cone pulley, on the end of the motor spin e driving a cone pulley and projector with belt fork gear arranged to move the drivin belt along the cone until the desired speed s attaine What I clalm and desire to secure by Letters Patent is:-

the magnetic field.
