SPECIFICATION forming part of Letters Patent N0. 766,040, dated July 26, 1904.

Application iiled January '7, 1901. Serial No. 42,315. (No model.)

To all whom it 17mg/ concern:

Be it known that 1, JAMES BARNES HUM- rnanrs, residing' at No. 146 East lhirty-seventh street, in the borough of Manhattan, in

the city and State of New York. have invented certain new and useful lmprovements in Belt Conveyer Apparatus for Distributing Material into Tanks, Sac., of which the following is a description, referring' to the ac- Io companying drawings, which form part of this specification.

This invention is particularly adapted to be used in conveying ores to leaching-tanks containing' cyanid, the cyanid being used for the extraction of gold or other metals; but l b v no means limit or restrict this invention to such use.

One common process heretofore in use has been to dump the ore from cars which are 2o run on a trestle over the tank; but by this means the ore is dumped in one part of each tank, and as a result the finer particles remain in a mass and become packed together.

By the improved device a nearly-even distribution of the ore over the bottom of the tank is obtained, the action of the cyanid is more complete, and very low-grade ores may be worked at a profit.

ln the drawings, Figure l is a side eleva- 30 'tion of the ore-conveyor and leaching-tanks. Fig. 2 is a plan view of the same. Fig. 3 shows the settling-tanks in section and the apparatus used for elevating the ore tothe level of the conveyer shown in Figs. 1 and 2. Fig. 4 is an enlarged detail view of a suitable tripper or delivering device.

1n the drawings like reference-letters designate like parts.

The tine ore or pulp is discharged from the 40 settling-tanks Fig. 3, through the pipes onto the conveying-belt m, which is carried on the idler-pulleys r, the idler-pulleys being arranged as shown at the right in Fig. l. The con veying-belt m, is actuated by the mechanism fr, which is driven from a source of power y), the loaded portion of the belt passing from left to right up an incline, as shown.

W'hen thc belt reaches the tripping mechanism o, which tripping mechanism is the same as that described in my patent application Serial No. 17,804, filed May 24, 1900, and patented No. 673,539, it discharges the ore from the belt into the chute n, which is also shown in Fig. l.

In order to discharge the material from the conveyers, suitable trippers, as stated, are provided, one form of which is shown in Fig, 4. The framework O is provided with wheels l), a discharge-hopper R. and the upper and lower pulleys S, over which the belt g runs, in the form of an ogee curve, so that the material is delivered from the belt into the chute e. According to this construction it will be seen that the tripper may be moved in the direction of the length of the belt and may therefore deliver material from the belt at any desired point.

The leaching-tanks c contain the cyanid solution, and between them is erected the framework (I, carrying the guides .e and rails upon which x'est the wheels n. Upon these rails is mounted to travel a complete conveying-belt apparatus, the framework of which forms the traveling-bridge crane 7), mounted ou the wheels e. This mechanism is actuated by the motor fr, which transmits power to the wheel y'w and the belt by appropriate gearing mechanism, as shown in Fig. Q. The motors .fr also impart motion to the frame along the rails on the elevated structure n'. This conveying-belt passes over the end wheels w and w and is of suilicent length to reach below the chute i and extend over all of the leaching-tanks, A movable tripperf, for the purpose of deliveringmaterial from any point on the length of the bridge upon which it is mounted, which is similar to thatin my abovementioned application and as above described, is mounted upon the bridge and is free to travel across the same. The conveying-belt g discharges into the chute c, which chute travels with the tripper. This tripperlneehanism is provided with automatic starting and stopping devices to allow of its being adjusted at any point upon the bridge.

The operation of the device is as follows: The ore in the tank is discharged onto the conveying-belt m, from which it is discharged through the chutes )l and onto the eonveying-belty by means of the tripper. It moves along the belt g/ until it reaches the tripperf. from whence it is discharged by the chute f into the tanks c. drawings. the bridge is mounted upon the wheels i'. which travel on the rails nl'. liy this means the bridge /i can be placed over any desired part of the tanks c. and by a further :uljustment by means of the tripperf the ore can be evenly distributed over the surface of the tanks. By actuating the bridge continuously at a very slow speed say at twenty or thirty feet per hour and by actuating the tripper automatically. so that it will travel the length of the bridge and back again every few minutes. the material may be automatically distributed over the surface of the tanks. 'here the circular tanksare used. thelength of i'novement of the tripper should be varied at different portions of the tanks. rlhe cars rj. running upon the tracks receive the ore from the bottom of the leaching-tanks and by means of appropriate switches can be placed under any desired part of the tanks to receive the material from thc tanks when it is desired to empty them.

According to this invention it will be seen that a plurality of coi'perating belt conveyors are provided with delivering devices therefor adjustable relatively tothe conveyers. and the conveyers may be adjusted to deliver a eontinuous stream of material from one of the deliveringdevices at any point in a given area. Means are provided for transferring material from one bell conveyer to the other. and the belt conveyers are relatively adjustable.

'hat l desire toclaim as the novel and chal'- acteristic features of my invention are the following:

As will be seen from the y and adjustable lengthwise of the belt. substantially as set forth.

4. 'lhe combination of two conveyors disposed at an angle to each other and one adjustable relatively to the other and an adjustabie d iseharging device cooperating with each conveyer. said discharging devices cooperatingl to discharge material at any pointthroughout the extent of the two conveyers.

The combination of a conveyer. a stationary support therefor. a movable bridge disposed at an angle to said eonveyer and its stationaiy support` a conveyor on said movable bridge. a discharging device adjustable on the vlixcd support and cooperating with the conveyer thereon. and a discharging device on the movable bridge adjustable from end 3 to end thereof and cooperating with the conl. ln combination in a conveying apparap tus. a movable conveying-belt framework'. means for movably supporting said framework. a conveying-belt mounted and actuated upon said framework. and means adjustable lengthwise of said belt fordischarging material therefrom. substantially as set forth.

2. ln combination in a conveying apparatus. a movable conveying-belt framework.

means for laterally moving and supporting said framework. a conveying-belt mounted and actuated upon said framework. and means veyer on the bridge to discharge material at any point throughout the length of the latter.

b. The combination with a fixed trackway and a` conveyer thereon. of a traveling' bridge disposed at right angles to said trackway. an endless con veyer extending lengthwise of said traveling bridge adapted to receive material from the first-mentioned conveyer at any point along the tixcd trackway and an adjustable tripper on the bridge and cooperating with the conveyor thereon to discharge material from the bridge-convcyer at any point between the ends of the bridge.

7. The combination with a series of bins or receptacles and a rail at cach side thereof forming a track, of a movable bridge mounted to run on said track and disposed over the bins or recmitacles, an endless conveyor on the movable bridge. a stationary support disposed beside the series of bins or receptacles and at right angles to the movable bridge. a conveyor on the stationary support, an adjustable tripper adapted to discharge from the conveyer on the stationary support onto the conveyer on the bridge and an adjustable tripper on the bridge cooperating with the endless conveyer thereon to discharge material from said endless conveyer on the bridge into any vpart of any of the bins or receptacles.

The combination of a conv ver mounted onV a stationary support. a traveling bridge disposed at an angle thi-ireto. an endless conveyer on the bridge. means cooperating with the inst-mentioned conveyer for discharging onto the conveyer on the traveling bridge and adjustable means coogarrating with the conveyer on the bridge for discharging atan angle thereto.
