This invention relates to long range haulage by belt conveyors, and has for its principal object to provide for continuous haulage in opposite directions while permitting any conveyor unit to be separately emptied, stopped, serviced or repaired without interrupting the continuity of flow in either direction- Generally speaking, this is accomplished by providing two tandem series of belt conveyors, side by side, running inopposite directions with all the conveyors in each; series running in the same directionbut opposite to that of the other, and each (except .the last) normally delivering to the next in.series,togprovide continuous flow throughout each serieaand equipping each con-,
veyor unit ,(except, the. last) .in each series with means to transfer a load from itsupperrun to the lower run of the; next conveyor in the other series, and means to transfer load from its lower run to the upper run of the next conveyor in the other series. I r
With this arrangement, by. merely throwing agate, any conveyor or unit can be .by-pas'sed without interrupting the continuity of now in each direction. The by-passed conveyor'can be stopped, loaded or emptiedwithinits own length, and canbe subjected to, any sort of maintenance,
service,;repair,' or replacement while the haulage continues uninterrupted in both directions.

Fig. 8 is a perspective view of thefour-endsections illustrated in-Fig. 4.
These diagrammatic illustrations are chosen for simplicity, and preferred for that reason.-
In Fig. 2, the diagram showsaconveyor unit A- for haulage to the right on the upper run, and to the left on its lower run. its head end 10 is arranged to deliver to the tail end ll of another unit B through a normal service chute indicated,
by thearrow I2.
The tail end I 3 of the .conveyor unit A is arranged to receive from the headend 14. of the;
conveyor unitC through anormal service chute indicated by the arrow I5.
Practical considerations limitthe length of a single conveyor unit, but an arrangement such as indicated in Fig. Zissatisfactoryfor long range, haulage by any number of units in a series. In Fi 3, a n y un t D i9 7 ma -h u ag to the left on the upper run has its head end l6. arranged to deliver to the tail end H of a conveyor unit E through a normal service chute l8, and its tail end I9 to receive from the head end 201 ofa conveyor unit F through a normal servic chute indicated by the arrow 21. The units A, B,"and C correspond to those" shown at the upper side of Fig. 1; and the units D, E, and'F correspond. to those shown at the lower side of Fig. 1. a a V r In Fig. 8, the intersection or overlapping of thehead end 14 with the tail end l3 of the conveyors C and A, respectively, and the head end Iii with the tail-end I! of the conveyors D and E, respectively, are shown in perspective.
From this, it will appear that the upper run 22- of the conveyor unit C has its head end 14 arranged to deliver through' the normal service chute I5 to the 'upper run 23 of theconveyor-A. Also, there is provision by throwing a gate 24 for delivery instead from" the upper run -22 through an auxiliary service chute or byepass chute 25 to the lower run 26 of the conveyor unit D, which is travelling tothe right in the same direction as the upper run 22 ofthe conveyor unit C. I Also, in Fig. 8, it will be seen that the upper run 21 of the conveyor unit D has its head end arranged to deliver through a normal service chute [8 to the upper run of the conveyor unit E, or by meansof a gate 29 to deliver through an auxiliary service or by-pass chute 30 .to the lower'run 3I-of the conveyor unit -C.
Assuming the section Fig. 5 to be taken on the line 5-5 at the right in Fig. 4, the normal service chute l5 appears at the left in Fig. 5 leading to the inclined portion of the upper run 23 of the conveyor unit A, while the auxiliary service chute 25 extends across to the conveyor D of the other series, and delivers .Onto ,the inclined portion of the lower run 25. 7
Assuming that the conveyor unit A is to be by-passed by running the material from the upper run of the unit 0 along th e lower @1126 of the unit D, it must then be transferred to the upper run of the unit B. This is accomplished by an auxiliary service or bYfiRfl Sfi chute which is shown at the left in Fig.4. betweenthe lower run 26 of the unit D and the upper run 33 of the unit B. Its positionisalso indicated in Fig. 3 by the arrow 32.
The unit E in Fig. 8 is shown with accruesponding auxiliary service or by-pass chute 34.

Also, each .tailend 'in the series, except the; last, will have an auxiliary chute corresponding to those shown .at 321and 34 .in Fig.3 and :3! .in Fig. 6 for connecting athe lower run of ..th e.,one conveyor to the upper run of the nextin the opposite series.
With this arrangement, merely throwing the corresponding gate to change -the transfer from a normal series chute to an auxiliary or-by-pass chute willbe suflicient'to cut-out aconveyor unit. It may then be stoppedirnmediately. :It may be allowed to clear itself by running its length, and afterwardsstopped. Hence, it-will be available for any sort of inspection, service, repair, replacement, for any length of time while the flow co ti ues .in'ho hr-di eot ohs.un nte rupted. The operator'does not have to choose his time or conform it toahyfictionby apy otherv operator. Throwing the igate one yvaybylpasses the unit. Throwing it the,g,other way,p uts itv back in service.

The many advantages oi a conveyor system embodying the present invention may be illustrated by the followi g:

Any unit ylbe' topp d io m nor iormaior of belt conveyors in tandem 113g cause without interference with the flow in either direction.
Any unit may be serviced to any extent from some small adjustment to replacement of belts and motors without shut-down of any other part of the system. Hence, regular and adequate service may be expected. l
