-- "In machines trit types disclosedby the above-mentioned patents, there is a main frame" or body supported on four iordinary 'wheels adaptedtofrest on track rails or on the ground; On the frame or body is: aforlwarddirected jib on which isan endless apronin front of which'is a shovel associate'dywith nieanslforactuating the shovel for taking 'material from the grounder-floor and delivering the materialto the endless apron to be carried backward for discharge from the rearendof them'achine, fj

F5, and rests"rotatably inj'the outer bearby the shovel and said shaftare"; compelled to rockin'unison.*-

The forward part'of each'bearing p'iece, F1, is rounded concentric with the shaft, F6. Thus a semi-circular edge is formed. A' cast steel boot', F11,is curved to'be concentric with the .shaft,F6; and has its ends bearing against the inner'face of the semi-circular part of eachbearing piece, F1." (Fig. L5.)

At each bearing-plat'ethere is a side plate,

obliquely'forward and outward. 'The' rear edge of the shovel bottom, F7, iscut tomeet the front face of the boota-nd the oblique faces of the' platesf, F13,- The upright sides,fF8

When the shovel is thus under the material, it is: to

be turned on the shaft, F6, to which the lower bearings, F10, of the shovel are secured, as already described. g

This turning .of the shovel raises its forward part until the bottom, F7, of the shovel is about even with the upper edge of the boot, F11, and is sufiic ientlyinclined toward the conveyor belt to cause the material on the shovel bottom to slide downward and rearward onto the conveyor belt. When the material has been thus discharged, the shovel is to be turned in the reverse direction to again be in position to receive materia'l by being moved forward by the bodily forward movement of the machine, These movements of the shovel are to be carried on indefinitely. The mechanism by which these movements are effected. will now be described.

At each side ofthe shovel, a wrist, F15, eX- tends outward from the upper bearing, F9, and into the bearing, F16, on the forward end ofthe adjacent pitman rod, F17. The rear end of said pitman rod has a bearing, F18, which receivesthe wrist, F19, on the crank, F20, which is fixed on the crank shaft, F21, which rests in bearings, F22, seated on the side members, C24,.of the jib yoke.

longitudinal strainson said rod. wardsectionof the rod 1s-.fixed the forward On eachpitman rod, F17, is a turn buckle, T, threaded in the usual manner'on two sections of said rod. (Figs. 1 and 2.) At one endof the turn buckle a jam,nut,jT1,.surrounds the rod. Its function is to set or bind the turn buckle after the buckle has been adjusted for varying the length of the rod.

This turnbuckle is to be regarded as. screw mechanism for manually adjusting the length ofthe rod. On each pitman rod is also placed cushioning means for yieldingly resisting On theforend of a-:-bar re'l, S. In the rear end of said barrel is a -bearing,S1, in which rests slidably the middle section of the rod, F17. On

the forward end of said section isfixed a head, S2, which is slidable' in the barrel, S. Between said head and the bearing, S1, an

expanding coiled spring, S3, surrounds said middle section and yieldingly resists'forward movement of the bearing, S1, and the barrel forward part of the shovel.

S, and the forward section of the rod and the shovel bearing, F9, whereby limited downv ward movement of the front of the shovel is yieldingly resisted. Withinthe barrel and in front of the head, S2, is an expanding coiled spring, S4, which yieldingly resists rearward movement of said barrel and the forward section of the rod and the shovel bearing, F9, and upward movement of the Permitting such upward movement of the shovel is desirable when the lip of the shovel, during its forward movement, meets a rising surface, and such downward movement is desirable when the lip of the shovel meets a descending surface. Said springs also permit yielding as may be required when the forward partpof the forward jibsection rises or descends rel,- ative to the forward part of the rear section of the jib, as will be described further;

Such movement is then needed, because on. the crank shaft and the hinge of the forward j ibsectio-n are not in the same axialline;

For driving the crank shaft, F21, a sprocket wheel, F23, surrounds the crank shaft, F21, between the right hand crank, F20, and the adjacent bearing, F22, and hasahub, F24, seated in and extending through the bearing,

F22. V The part of the hub whichextends beyond the bearing is flanged outward to overlap the outer end of said bearing forholding said hub against outward. movement through said bearing. '(Figs. 1 and 2.) Said end of the hub is also notched to make one member of a toothed clutch which is adapted to'be engaged by the sliding keyed F30,securedto]the inner face of theright hand yoke member, C24, and havingits rear end coupled to :means for shifting (not shown). When the forward end of the lever, F29, 1s driven toward the. right, the clutch -men1ber, F25, is driven into engagement with .the hub, F24, of the wheel, F23. Then the crank shaft, F21, receives rotation fromxthe sprocket wheel, F23. Then the. cranks F20,

are turned and eachpitman isIreciprQcated for the reciprocation of the bearings, F9, of the shovel, whereby the shovel is put through its movements. v I claim as my invention, In a shoveling machine, the combination with a jibof a shovel having bearings, a pair of duplex bearings at the forwardend of the jib, said bearings being on a common axial line whichis horizontal and transverse to the length of the jib, the inner bearing of each pair being'of larger diameter than the from a source of power not adjacent outer bearing, a rotary tubular shaft having one end resting in one inner bearing and having its other end resting in the other inner bearing, conveyor Wheels surrounding and fixed to said tubular shaft adjacent each inner bearing, and a shaft of smaller dia1neter extending loosely through the inner bearings and resting in and extending through the outer bearings and into the shovel bearm s. i in testimony whereof I have signed my name, this 7th day of September, in the year one thousand nine hundred and twenty-seven.
