ing Apparatus, of which the following is a` specification.

This invention relates broadly to loading apparatus, and more specifically to a powerdriven shovel and conveyer for loading coal and like materials in cars or the like. j

lThe primary object of the invention is to provide an efficient apparatus whereby materials, such as coal, may be rapidly loaded upon cars for transportation, and which is especially adapted for use in mines.

A further object is to provide a powerdriven apparatus of the character mentioned which is automatic in its operation, lwhich is strong and durable in its construction, have' ing but'few parts liable to become out of order, and lwhich may readily be shifted from place to place as occasion requires.

l/Vith these and other important objects in view, the invention resides in the features of construction, arrangement of parts and.

combinations of elements which will hereinafter be exemplified, reference belng had to the'accompanying drawings, 1n which- Figure 1 is a side elevation of the inven tion;

Fig. 2 is a front end elevation; Fig. 3 is a rear end elevation; Fig. 4 is a top plan View; Fig. 5 is an enlarged section taken substantially on line 5 5, Fig. 4;

' reverslng gear.

Fig. 6 is a side. elevation of the front end portion of the machine, showing vario-us positions assumed by the shovel; and- Fig. 7 is an enlarged detail section of the Referring Ato said drawings, which like designating characters distinguish like parts throughout the several views- 1 indicates a large gear which is mountedl horizontally beneath the upper part, as-the platform 2, ofa truck-carried fran 1e;sa1d gear being keyed or splined upon and rotatable with an upright pin or shaft 3 whichhas its lower end suitably disposed, as in a j portion 4 -of'the truck frame .whlch underlies said gear 1, the latteibeing spaced away from said portion '4 andpsupported by a suitable'bearing-like washer 5 within which resting upon the end of the latter is one end of a crank-arm 7 whichA has its opposite end pivotally connected to the rear end of a con` necting rod or pitman 8 .which has its front end connected pivotally to a horizontally ldisposed carriage 9. The crank-arm 7 is interlocked with said huby'6 in a suitable manner, as by a downwardly projecting stud or pin 10 carried by said arm and seated in a socket 11 provided therefor in the end of said hub.

Said carriage 9 is longitudinally slidable over parallel gibs 12 0r upon the front end of an underlying turn-table 13 which carries said gibs. Said turn-table overlies and has rotary movement upon or with respect to a plate or table 14,-herein depicted as of circular form, which is rigidly mounted upon the truck platform 2; Said turn-table has'a downwsadly-extending hub 15 disposed for rotary movement about the hub 6 of gear 1.

The carriage 9 is disposed between said gibs 12 which have their opposing faces undercut to form guideways 1 6 in which portions of said carriage are received, tipping vor overturning movement of said carriage being thus effectually prevented.

Mounted upon said carriage 9 are suitable l bearings, as ,17, in which is journaled a effecting rotation of said Wheels.

Extending diamet'ricallyV across the outer face of each wheel 19 and either fixed to or formed lntegral with such wheel is a crosshead or crank 22 which vcarries at one end a crank-pin 23 upon .which is pivoted the rear end of an arm 24.l The front ends of the oppositearms 24 are pivotally mounted upon trunnions 25 carried by the opposite sides 26 of a shovel or yscoop which is generally designated by the reference letter A and which lll@ 25 drive-shaft of an appropriately located elecshown.

Disposed in meshing relation`tothe. gear 1 is a pinion 29 Xed upon an upright shaft journaled in suitable bearings carried by the frame and in an upright sleeve-bearing 31 mounted upon the top of said frame. Fixed upon the upper end of said shaft 30 is a bevel-'gear 32 adapted to be operatively' engaged by one or the Aother of two oppositely facing bevel-gears 33. and 34 accord ing as it is required to drive one direction or the other. Said gears 33 and 34 are fixed upon a shiftable sleeve 35 and are spaced apart such a distance that they cannot simultaneously engage the bevel gear 32. Said sleeve 35 is keyed upon and shiftable along a transverse shaft 36 journaled in I suitable bearings, as 37, carried by upright frame members 38 mounted upon the platform 2-or other suitable portions of the truck frame. A spur gear 39 carried by said shaft 36 has disposed in driving relation thereto a Ipinion 40 carried by the tric motor 41.

Associated with the sleeve 35 is suitable means, as the connected pivotally mounted lever members 42 and 43, whereby shifting of said sleeve in either direction may be.

accomplished.

Disposed in a suitably elevated position, as upon theframe members 38, are the side members of a rectangular boX-like inclosure 442t constituting a part of a conveyer which is herein designated generally by the numeral 44. Said conveyer has the forward portion thereof disposed in overhanging relation to the truck platform 2 and to hereinbefore described mechanism carried by saidplatform, and the rear end of said conveyer extends. rearward from its supports and with respect to therear end of the truck by which said supports are carried, so that it may occupy a position overlying or overhanging. be loaded, as is best shown in Fig. 1. A plurality of transverse rollers 45 are located -within the inclosure 44, the same having their shafts suitably journaled, as in the side members of said inclosure. Mounted on said rollers to be actuated by the latter is an endless traveling conveyer or apron 46 upon frwhich the material being loaded is dumped from the 'shovel and by which said material is carried rearward and dumped into a car overhung by the rear end of said conveyer.

Power forproducing travel of the apron 46 may be applied in any appropriate manner, as by a sprocket chain 47 connecting a sprocket wheel 48 on the end of the shaft of one of the rollers 45 to a sprocket wheel 49 carried by the shaft 36.

For changing the direction of the thrust said shaft in part of the a car or the like to,

of the shovel to any desired angle with respect to the longitudinal line of the machine, the turn-table 13 is made laterally shiftable. A worm-gear 50 is mounted to rotate on the hub 6 of gear 1 .and is fixed to said turn-table, as by means of bolts 51. A worm 52 carried by a transverse shaft 53 is operatively engaged with said worm-gear. Said shaft is located rearward with respect to said worm-gear and is ournaled in bearings, as 54, mounted onthe truck platform 2. While said shaft' may be driven in any suitable manner for accomplishing rotation ,of the turn-table for shifting the shovel laterally, ll prefer to employ a sprocket wheel 55 located on said shaft, and to connect the same by means of a sprocket chain 56 to a sprocket wheel 57 which is rotatably mounted on an end of the shaft wheel `has a dentated hub 57.a adapted to be operatively engaged by a correspondingly dentated clutch-member 58 which is mounted on said shaft 36 and which is adapted to be 36. Said sprocket shifted into and out of interlocking relation the other lation to the bevel gear 32 according as it is desired to rotate the shaft in a forward or reverse direction. explained, the shovel anism are operable with equal facility irrespective of the direction of rotation of said shaft 36. Motion imparted to said vbevel gear 32 is communicatedthrough the shaft 30 andthe pinion 29 to the large gear 1,

.thence through the hub 6 of the latter to the crank-arm 7, pitman 8 and carriage 9,

the latter being actuated to move back andl forth in a reciprocatory manner between vthe glbs 12 located on the front end of the turntable 13. With such movement of the carriag'e 9, the wheels 19 tf'avel back and forth upon the trackways 20, rotation as distinguished from sliding movement?` of said wheels belng insured by the inter-engagement of the spurs 19a thereof withA the seats or `holes21 provided in said trackways.

Rotation of said wheels 19 in a forward,

direction actuates the shovel A to advance, and vice versa. Forward rotation of said wheels following that in which the shovel initially seats upon the ground or floor,

shown in full lines in Fig. 6, results in said shovel being advanced along saidV ground or floor to or toward the forward dotted-liney position shown in said figure for scooping As will hereinafter be and its actu-atin g mechmeager Awheels 19, until it reaches said initial seating position, whereupon the under'sides of 'the inclined shovel arms 24 engage laterally projecting fulcrum-pins 60 carried. by ends of the cross-head-like cranks 22 opposite the ends thereof whichcarry the crank-pins 23. Continued rearward rotation of said wheels 19 results in said arms 24 and the loaded shovel. being elevated from said initial shovel-seating position to the substantially upright position shown in dotted lines in Figs. 1 and 6, and in full lines in Figs. 2 and 3. Sli htly prior to said position `being reache an arm 61 carried by the back 28 of the shovel engages an arcuately curved outstanding horizontal member or rim 62 carried by the front end of the box-like inclosure 44a of the conveyer, whereby said shovel is swung to the rearwardly tipped position shown for dumping its contents upon the forward end of the apron conveyer 46 by which said contents are conveyed rearward, as hereinbefore described.

|The, final shovel-dumping position is assumed when the crank-arm 7 and the pitman 8 occupy their rearmost positions with the latter overlying and in parallel alinement with the former. Consequently, continued rotary movement of 4the last-mentioned parts serves to reverse the direction of movement. of the carriage 9 and the wheels 19 whereby the shovel is returned to its initial seating position and is thence again thrust 'forward into the bank or pile of material, as

aforesaid. rThus, as is apparent, uninterrupted operation, without reversal of the mechanism which effects reciprocation of the shovel-carryihg mechanism is permitted. Further, when in the operation of the shovel, the same may be advantageously advanced into the bank or pile of material to the limit of its forward movement, the reciprocationproducing mechanism may be driven uninterruptedly, or without reversal, it being obvious that, when the shovel has reached the limit of its forward travel, the crank-arm 7 and pitman 8 occupy positions in extended alined relation, and that continued movement will act to return the shovel in rearward direction. However, when it is impracticable to advance the shovel to the limit of its forward movement, as when the bankl or pile of material to be handled lies close to the initial shovel-seating position so that the shovel receives its load with a thrust short of that of which it is capable-that is, with 4a fractional part of the possible thrustthe sleeve 35 is shifted on the shaft 36 in the manner hereinbefore indicated to effect a reversal of the direction of rotation of said shaft and," consequently, of the mechanism intermediate said shaft and the carriage 9 for moving the latter rearward, thus accomplishing retraction of said shovel. Such reverse movement of said mechanisms will be continued until the shovel is again loaded, whereupon the sleeve 35 may again be shifted to effect retraction thereof, and so on,

To prevent rearward tipping or dumping movement of the shovel while it is being retracted to the point where elevation thereof begins, rearwardly extending bracing members, as 26, preferably constituting eXtensions of the shovel sides 26, are provided. On the other hand, to prevent forward tipping of the shovel which would result in discharge of its load during elevation thereof, fulcrum pins, as 63, are suitably located on said members 26a for assuming underlying engagement with the shovel arms 24 at the moment when elevating movement commences.

Angular members or feet 64 are preferably carried by the rear ends of the shovel arms 24 in a position for seating upon the platform 2 to prevent rearward tilting movement of said arms beyond the requisite substantialiy upright position assumed by the latter when shovel-dumping position is reached.

e As is obvious, the carriage 9 may be wholly supported by the shaft 18V upon which the wheels 19 arev mounted, or it may be supported by and have sliding movement on the gibs 12. In the latter case said wheels serve merely as shovel-actuating elements.
