plate 4 provided at its ends with flanges b secured to the inner faces of said side plates 1 by means of screws or other fastening de vices.

The frame of the machin as constructed is supported upon the wheels 7 and. S rotatably mounted on studsi) and a shaft; 10 respectively, thelatter being journaled in suitable hearings in said side plates 1 Mountits ohicct to provide a simple and eilicicnt l machine of this character.

'lhc invention consists In the novel features of (I )I1' lIllCllOll and co1nlnnat1on O parts herciua t'ter fully described and claimed.

In the accompanying drawings illustratiug my invention: Figure 1 is a front elevation of a machine constructed in accordance with my invention. Figs. -2 and l are views in elevation of respectively opposite ends of the machine. Fig. l-- is a central vertical longitudinal section of the same. Fig. is a detail inverted plan riew showing the di ks or saws employed and the gear train for actuating the same.

In unloading coal from cars it is necessary to provide means for penei rating the mass of coal as nearlv as possible adjacent the floor of the car. Where. large lumps and small pieces are intermingled as for ex ample in mine run coal, or where block coal or in fact any of the larger sizes are to be unloaded, penetration is very dillicult as will be obvious, and consequently it is necessary to exert considerable power in effecting the same.

My invention has for its principal object to provide. a machine for unloading coal from cars which is equipped with power actuated means for penetrating thc mass of coal adjacentthe floor in a positive and reliable manner and which is further equipped with eflicicnt means for removing the body of the coal after such penetration has been efiected.

My said machine comprises a frame consisting of suitable side plates 1 secured together at a plurality of points and mamtained parallel by means of cross rods 2 secured in said side plates at their ends by means of nuts 3 in any usual. and wellknown manner. The machine is further provided at the bottom thereof with a cross bevel gear 32.

ed upon one of said side plates is a bracket 11 upon which a motor 12 is supported, said motor being preferably electric. On the motor shaf'a here is mounted a spur pinion 13 which meshes with a spur gear 14 rigidly moun -2c upon shaft laq'oumaled in suitable bearings ni'the said side plates 1 of the machine. Said shaft 15 carries a spur pinion 16 rigid therewith and meshing with a Spur gear 17 rotatably mounted upon a stud 18 on one, of said side platesll Rigid with said spur gear 17 is a spur pinion 19 which meshes with a spur. gear 20 011 a counter-shaft- 21 suitably jourualed in bearings in said side plates 1. On said countershaft 2] and upon countersh'afts 22, 23 and 2% respectisely, are mounted pairs of sprocket wheels 2G, 27 and 2S respectively, over whiclr sprockct chains 29 are trained; the latter being equi pedi at regular intervals with buckets 30 or the reception and elevation of coal. The said sprockets 9.6 are idle as are also the sprockets 28 While the sprockets 27 serve to transmit movement.- to the coun-Jershaft 23. The latter is provided at one end with a bevel gear 32 rigidtherewith and meshing with a bevel pinion 31 on a vertical shaft 3% suitably supported in a bearing formed in a bracket. 6 ha .ing flanges 31 secured to the outer face of one of s id side plates 1 and in a bearing .35 carried by said side plate, the latter being slotted at its lower end for the purpose of pcrmicing the said spur pinion 33 to pro ect, into engaging relation with said On the. lower end of said shaft 34 immediately above said cross plate 4 there is rigidly mounted a spur gear 36 which likewise projects through said slot in said side plate and which meshes with an idle gear 37 rotatably mounted on a stud carried by said cross plate 24 and which in turn meshes with a spur gear 38 rigid with the disk 39 which is preferably equipped with teeth similar to a saw on its periphery;

" mounted on a spectively opposite directions.

- the stud 49 and rigid with which is pinion 50.

lever 66 the said disk 39 and spur gear 38 being stud 40 secured to said cross plate 4. A-similar disk 41 rigid with a s ur gear 42 is driven by means of the pair of idle spur pinions 43 from said gear 38, the said disks 39 and 41 being thus driven in re- The said disks 39 and 41 are disposed very near the lowest point in the machine, said disks being adapted tcforce their way into the mass of coal to be loaded adjacent the bottom of said mass at the same time that'the machine moves forward. Motion is transmitted to the frame of the machine from said motor .12 in the following manner, to-wit: The

shaft 21 is equipped at its other end with a spur pinion 44 which mrshes with a spur gear 45 on a stud 46 on the said plate 1 farthest removed from the motor 12. Rigid with said gear 45 is a spur pinipn it? which meshes with a spur gear 48 mounted upon a--spur The latter meshes with aspur gear 51 mounted on a stud 52 on said side plate said gear 51 being maintained constantl slowly in rotation. On said lastnamed; side plate 1 is a stud 53 on which there is rotatably mounted a sprocket wheel 54: and a. spur gear 5-5 rigid with said sprocket. -b'aid spur gear 55 meshes with two spurgear's 56 and 57 respectively, both of which are rotatably mounted on studs 58 and 59 respectively, mounted on a rocking plate fiOpivotalIy mounted upon the said stud 53. Said plate 60 is provided with an arm or extension 61 provided witha slot- 62 in which the crank pin 63 on a crank arm 64 engages; the said arm 64' being rig idly mounted upon one end of the shaft (35 journaled in suitable hearings in the side plates of the machine and upon the other end of which there is rigidly mounted a equipped with. an auxiliary lever 67 normally maintained at one limit of its movement by means or" a spring 68 engaging a longitudinal movable plunger 69 pivotally engaged with said lever 67 and fit'ltS lower end carryinga dog 70 adapted to be engaged in notches 71 in aplate 72 mounted upon said bracket 11. Said lever 66 when in the position shown in Fig. 3-'ma.intains said plate 6 in the position shown in Fig. 2-. By moving said lever 66 so I that the dog 7 0 engages in one of the notches gear 51 or to throw nearest adjacent the ends of said plates 72 it will serve to swing the said plate 60 so as to throw the-gear 57 into mesh with the the gear 56 into mesh with the gear 48. On the shaft 10 there is rigidly mounted a sprocket 73 over which and said sprocket 54 the sprocket chain 74 is trained so that when the gear 57 meshes withthe gear 51 the frame of the machine will be moved slowly forward toward the.

mass of coal to be penetrated and at the same time the buckets 30 will scoop up such idle rolls 7 8 arejournaled; said rolls being adapted to engage the side walls of the car and thus prevent lateral movement of the machine or deflection thereof from a true straight line of travel. 4

It will be obvious that the side, plates 1 will be maintained spaced some distance from the sidewalls of the car andin order that the coal nearest adjacent said side walls shall be removed together with the body of coal 1 provide upon the forward edges of said side plates 1 hinged plates 7 9 which are adapted at theirforward ends to contact with the side walls of the car and throw the coal nearest adjacent said side walls inwardly inposition to be engaged by said scoops or buckets 30 and thus remove I claim as my'invention:
