7 For driving the chains 107, a motor 112 is provided vwhich is mounted. upon'a bracket 113 secured to the side plate just iii-front of the rack 97, as'shown-in Figs. 5and 9.. The motor 112 drivesa shaft 114 which eX-- tends across the machine and which is connectedwith the motor'by a pinion 115and a ear- 116 carried "bya stud shaft1l7. #The shaft 114 is provided-with a plurality of sprocket-wheels 118 whichiengage the con veyercha'ins'107, as shown in Fig.- 13'. In

addition'to driving the conveyerchains 107,. V the shaft 114-is used to transmit motion from,

-themotor112 to the :shaft 99. Injorder that the shaft -99 'ma-ybe rotated in either direc--' tion, reversing mechanism is provided, as:

shown'in Figs. 5' and 17. A pinion 120 and;

- wheel 124 by a'sprocket chain 125 and the" without operatingitheworm'98 to shiftthe a sprocket wheel 121are loosely mounted on the end of theshaft 114 and maybe alternatelysecured to the shaft by a clutch 122 operated by a handle 123. Wheel 121 is connectedwith; a corresponding pinion-120 is geared to a pinion 126 onthe shaft 99 through a pair of idlers 127. By this arrangementthe shaft 99 maybe rotated in one direction through the sprocket wheel 1251 and in the opposite direction through the. idlers 127 The-clutch mayralso-be placed' inan intermediate position'so thatgthemotor 1'12-maybe used'to'drive the conveyer chams forward end of the machine.

I When themachine is being transported overithe trackrails' 3 the forward section is ,7 supported by wheels 128 which are journaled on the ends .of' arms 129 whichwarms are rigidly secured .to the opposite ends ofxa pair of shafts 130. extendinglongitudinally through a block 131:in which the shafts are journaled to rotate. The block 131 lspivoted to'a projection ,132 carried on the frame plate 95, a pin 133being used to connect the:

block :131 with the projection .132 'ata point midway between .theg'sides of the conveyer.

. The inner; endsof the arms 129 are provided with int'ermeshing gea teeth.;135 so thati alli fourfof the wheels 128 will swing upwardly or downwardly in f unison with one another relative-to the conveyer when the shaftsiflSO.

. are rotated; Oneof the arms 129 as shown in Figs. -5 and' 9, carries a segmental rack 136. which meshes with a=worm-137 journaled i in a bracket 13 8 rig-idly secured to the. block- 3 I V f131.--*;.Th'e wormg137 isvprovided'with a squaredend139 for receiving a socket wrench or crank 140 by meansof which the shafts j 130 may be rotated to shift the wheels 1128 5 relative to the -frameofthemachine.

The sprocket I For'the convenience of theioperator a'pair of running boards 141 is hinged to the sides ofthemachine, as shown in Figs. 1, 4 and 22,,

V and these'ru'nning boards may be swung upwardlyiifitis desired tomove' the machine I through a narrow opening, or if for'any other reason 1t is found convenient. j The car 37 which-receives the'mate'rlal-from the discharge end of. the loading machine is providedat its forward 'end'with" a downwardly swinging doo'r142 pivotally connectedto the car at 143K and which when open leaves the endof the car free to receive the discharge conveyer of the loading machine, as shown in F igs58 and 12. The-door 142 has acts asabumper andcoupling block by means ofgwhi'chthe' car is connected with r othersj'toPformi a' train. "Ajpin 145 extends :acros'sa slot 146 in-thefbar 144 and receives -:a hook for connecting the car with othersinf 1' th e t'rain. *The'" opposite end of the "car is provided with a bar 147 which forms afco mf N v I, c

plementary coupler for the bar 144 of an ad- V '80 :abar 144'securedtofthe'outer face'ther'eof 1 which extends a'crossthe 'endof the'car and jacent car in atrain. The bar 147 is pro vided with a slot 148 and a remov'able'coupling pin 149 which passes through'a linkof the coupling chain 150." The chain 150 is provided with a hook-151 for engaging the pin 1450f the coupling bar 144. -An'ysuitable latch such asis shown at 152'may be position; i

provided ar 'holding the door '142fin closed In the modification showii in Figs;- 23iand 24, thehollow shaftsshown at '5 in Figs, 4 and 15 are-replaced by solid shafts 153 and power is transmitted from the motor pinion 29 to the iopposite side of the frame of the machine by means ofa'flutedshaft 154 in-[ stead of ishafts 19 passing through hollow v shafts 5 as intheform previously described.

The fluted shaft 154 slides through-a sleeve 155 which carries; a bevel" gear'156 in position to IDBSlITWlththG motor pinion 29." The sleeve 155' is internally fluted to conformto viou'sly described. At the-side of the frame opposite theggear156r a pinion 158 meshes v with a gear 159-secured1to a shaftjournaled] in a'bearing160 and carryingat its'opposit'e endalpinionliil by. means of which the truck wheels 2 on that side of Y the 3 machine are driven. The pinion- 158 is provided with a hollowsleeve1 62 internally fluted to fit the periphery'of the sha'ft154. By this arrange; ment'powermay be transmitted across'the frame of'the machine so that the wheels "2 will be driven'in unisori onboth sides ofthe frames This arrangement may be used for I "propelling the machine-from'place to'place :15:

in the mine! and when it is desiredto operate the machine :for loadingspurposestthe shaft 154 may be withdrawnfromwithinlthe sleeve 162by means of ahand piece 163 so thatthe space between the side p1ates12 Will not be obstructed by the shaft. Since the WheelsQ are not used for. propellingthe machine during loading operation,- the shaft 154rwi1l not be neededat this time'so -that -it canbe With drawn entirely or drawn back sufficiently to clearthe space-between the side plates 12,130 permit the passageiof :inaterial along the conveyeriframee I a ln operationt the machineis first drivento the position in; amine chamber where loose fmat'erialis tohe loaded' and duringthe trans? portation of the machine from-place. to place it is supported in? the truck Wheels 2'and 128 at a/snfiicient height from; the flooftofithe mine-chamber to cause the nose piece 108 of V the machine to .clear'the upper "partqofthe track rails wover which the machine travels When the machine is brought into position to,
