(ci. 19a-eco) l This invention relates to shaker Aconveyors of the type utilized for-transportation of c oal or similar material-fromthe mining point tothe loading point 'in the mine., 1 k

5, `It has heretofore been impossible to practically ,producea shaker conveyer whichr wouldsuc'cessfully elevate material up aninclinevof any ap' preciablefgrade,` such devices being employed` only after the placement for the conveyer is level loor has a slight slope fromthe loading to the di'scharge point. VFor this reason- :it is necessaryV that these conveyershave some type ofelevator associated therewith for elevating the material to a' carloading position and 1theV multiplicity of handlings thus necessary Aforthe coal causes an excessive breakage thereof `inaddition to the excessive cost in maintenance.-

An important object of this invention is the provision of a shaking conveyor including horizon- 2U tal and inclined portions and so constructed that material may becontinuously moved `thereover without the provision `of riiiles or other devices which will damage the coal.

One of the principal reasons for the failure 25 of the ordinary type of shaker conveyer to elevate material moving therealong through any appreciable incline lies` in ythe factthat'the op# erating mechanism employed with such conveyersis ofsuch character that the materialdoesA 3U not come to restbetween alternate advancing strokes, with the result thatthe frictional en gagement between themat'e'rial andthetrough yof the conveyer is reduced toapoint wherefit is insufiicient to cause such elevation. Q

lll` further` andA specific object of .this inven-` tion is the provision of operating rnechanismfor shaker conveyers whichmay be either operated in the usual manner or` may` be so operated that `the material comesv to rest each stroke.'` f M i A further object ofthe invention is thefpro-y vision of v a novel andimproved trough construc-` tion which will admitof4 `provision of additional: frictional engagement between the 'coal,` or other materiahandthe troughwhile at;` the same time presenting a surface which will not break ordainage the material. A further-object of -the inventionis the provision of agnovel and improved transfer connec-` inclined sectionsl of .such a conveyer.` i Y v g A `Afurther object of the inventionis the provisi'on of a construction such that the dischargeendof the conveyer may be -disposed at an angle to the inclined portion thereof andlthus 'overlie i Fig.`5is a section on line 5 5 of Fig. 3;

the latter portionof this stroke by slowing down or stopping entirelythe motor 44 during the lati ter-part of-'the stroke.v I have at present illustrated shaft 45 as equipped with a cam'5l acting through arocker `52 `and a plunger 53-`u`ponia switch 54 which controls the operating `coils-W55l and VSil-4a of interlocked switches 56 and `56`-a.

Shunting the motor armature Aoi motorMis an adjustable resistance 51. if Switches 56 and 56-2-1; alternatelyclose this shunt-andone side of the` motor line. Through/a double throw switch 58, the switch '5S-af may be employed? to placethe adjustable resistance 51 infseries" with the armature. The' circuit Aofthe coil .5S-a of switch -a may be opened throughasuitable switch-"59. It willl befobvious that with switch 59 closed at SS-a'the motor will operate continuously andthe only actuation ofthe conveyer will be that `normally'givento" conveyers ments will cause aslowing down of; the motor,

Y and the switches one-applying a dynamic `braking'@thereto andthe others a reduction orinterruption of-kthe input thereto. The particular Vtypelof` dynamicibraking herein illustrated may, lof course, be varied 56 and SG-.aloperated in Avariousmanners.

F It is apparent that the adjustment of the re sistance 5l may be improper orsome unusual frictionmay occur during the'operation of Athisdevice causing the motor to cometorst with the Vrocker 52 bearing upon thedepressed.fportionof cam 5l,in which case the machine would fail to start. Pilot device 54-1a1 with antime Yelement somewhat greater than one lnormal cycle 'will-(now open the circuit to switch SB-c and close switch 56 causing the motor to` start. This pilot device may be of any or" the well known time element relays. Y .V The resulting stroke is diagrammatically illustrated by the solid line in Fig. 16, the pointX indicating approximately the point at which dynamicbrakingY of the lmotor begins its operation. It will be noted by comparison of these stroke diagrams that the 4entire added length of the stroke-is confined to therlatter half of the return or idle stroke, with the result that a sufficient interval is provided for the material to come to rest upon the trough so that it may vmove therewith.

The use of a rheostat permits the duration of the idle stroke to be adjustably regulated so that the the material to come to rest. 4'I'his is necessary due to the fact that transportation systems em-` trough the greater load is obviously imposed thereon which load, of itself, `acts as a brake,

necessitating themodication of theA dynamic braking applied at the motor. i L

f The-operating mechanism'further incorporates a-reel'BO, one end` of whichi'is provided1 with a ratchetl havingl'a'ssociated therewith an -operf ating pawl 62 mounted upon-a Vrocker arm'53 operated by a linkeco'nnectionwith 'one "of `the arins 49, as indicated at 64, and aholding pawl 65. Holding `pawl -653 is "withdrawable by 4a pedal "66, which pedal'maybeheld in its released position by a latch cam 61. The actuating pawl'EZ is nor-` mally held-out of engagement with the ratchet 6l v by a spring' 68 and is engageable with the" ratchet through an operating cord 69, preferably includingA a spring 10,. j Operating `cord v'69 is-extended to the operator-sl station lwhich is vat the discharge end of 4the `conveyer `and a cable 1l wound upon the'reel is extended fromithe reel about sheave wheel 43 thenback along the conveyer andi-is connected -to theendof atrain of cars C arranged alongside the conveyer through a -shock absorbing connection 12." This arrangement is employedassuming` that cars C are `.to l be moved in 'the directionV ofthe arrows on Figs.

3 and 4. In case movement ofthe cars isdesired in the opposite direction following loading; the cable will, obviously, be connected'` to the `opposite end of the train. When `loadi'ngofany caris i completed, the operatorV simply'v lexe'rtsla pull "on `thecontrol cord 69, thereby engaging the-'aetuat`` ing pawl and causing'the cable `to bewound upon the drum. After loading ofr a train of cars fis completedtheicable may be'izonnrected'toV the end of a-secondtrain and `allowed to pay outv 'by simplyY releasing the holding pawl 65. VIt will be obvious that by useof apparatusof this character manipulation ,of the cars being loaded is materiallyfacilitated.4 'f

AItmaysometimes be desirable to have the control of thecablereel accomplished electrically, in which case the actuating Vpawl 62 wouldbe controlled by a suitable solenoid and `push button switch at the operators*stationfavoiding'the use ofthe'control oord.` f 1 i 1w i Direct fcurrent appara-tus has ybeen used i for illustrating theprinciples involved, but it is "obvi'ous alternating current apparatusmay also be used for the purpose? with 'substitution of equivalentelements., 4 I e WhileI have i described"V thepropelli'ngappa-` Y ratus `as" employedfwith a conveyer including 5inclined l sections, Ait "willg'of course", be obvious that its usefulness is not limitedto ,such conveyers, as

it will increase the efficiency of any typeof shaker conveyer with whichiit is employed.v
