Application filed March 16, 1908. Serial No. 421,480.

ATo all whom it may concern: i

Be it known that I, lVILLIAM VHALEY a citizen of| the United States, residing at Knoxville, inthe county of Knox and State of Tennessee, have invented a new and useful Improvement 1n ShovelingMachines, of

Awhich the following is aspecication, re`f- 'in a. machine comprising (l) a sectionl which is, in effect, a car having four wheels intended to rest-'upon track rails; (.2) a conductor, conveyer,l or carrier supported by said car; (31) a jib crane section pivotally Imounted upon said car and projecting horizontally from the car; (4) a conductor, conveyer, or carrier vmounted upon said jib section in properl position to discharge upon the rs't'mentioned conductor, in whatever positiony thejib section may stand; (5) a shovel ory scoop supported at the outer or free end of said j ib section'and so controlled to move forward with its nose upon the floor or ground and take a load, lift the load y and move itrearwar'dand discharge it upon the second or forward conductor. Suitable power is to'be'provided for operating said accessories and saidshovel and turning said j ib horizontally and raising and lowering it, and propelling the car. ln the form illustrated by the drawings, an electric motor is used forl'driving the shovel and the front conveyer, and another electric motor is used for swinging and` raisin and lowering said jib section, propelling t e car, and driving the rear conveyor. l.

The mechanism described and shown herein is a modification of the mechanism made the subject-matter of my application Serial No. 381,624, tiled by me in the United States Patent Uice July 1, 1907. .As to specific features, the machine of Said application was designed to come within. certain. height limits, in order to adapt it for use in relatively low mine workings. The present machine ijs limited in the same manner het not to the'same extent. It is limited merely to proper heightv for work-ing in higher mine workings and ordinary tunnels.

In the accompanying drawings, Figure 1 is a side elevation, a portion being broken away; Fig. 2 is a plan of the same machine, portions of the conveyors and `other parte being broken away; Fig. 3 is a side elevation of the jib section and the front part of the car; Fig. 4 is a plan of the mechanism shownin Fio. 3' FiO'. 5 is a rearward continuation of the portion of the car shownv in Fig. 4, portions being broken away; Fig. 6 is a detail plan of the forward end ofthe rear conveyer; Fig. 7 is a section on the line 7-7 of' Fig. 5; Fig. 8 is an enlarged sectional eleva* tion on the line 'S-S of Fig. 4, looking in the 'direction of the arrow; Fig. 9 is a section on the line 9-9 of Fig. 8,.looling in the direction of the arrow, a portion being broken away;

Fig. 10 is a front elevation (portions being'- `broken away) of the 4machine as shown in Fig. 8; Fig. 11 is an upright transverse section on the line 11-.11 of Fig. 3, looking in the direction of the arrows, a housing having been added tothe bare framing shown in other iignres;l Fig. 12 is a horizontal section 4on the line 12--12 of Fig. 11; Fig. 13 is a section on the line 13-13 of. Fig. 4, looking in the direction of the arrow; Fig. 14 is a detail plan of the rear end of the rear conveyer; Fig; l5 is a detail side elevation of 'the front section of the scoop.

Referring to said drawings, A designates' the car; B designates the rear conveyor; C designates the horizontal swinging jib crane; D designates the conveyer supported by said. jib; E designates the scoop or shovel; F designates the rear electric motor; and Gr designates the forward electric motor.

In the form shown, the car has tour wheels, A1, secured rigidlyto axles, A2, resting in bearings, A3, on the longitudinal side members, A4, of the frame. Said side members are connected by several transverse frame members, A5. Upon the' frame formed by said members, A? and A5, are mounted all of the devicesvconstituting theoperative portions of themachine, including the jib. From the rear portion and at opposite sides of the longitudinalr middle upright plane of the frame rise two posts, A", and from the frontend at opposite sidesof the frame rise two posts, A7, to support the rear conveyor and the two forward posts alsoY portion of the rear conveyer is greater than i the width ofsaid conveyer. A bracket, AS, extends inward from each such post. To the inner Jface each post, AG, has secured a plate,'A0, upright and parallel to the length of the machine. Extending trom the plate, A, and the baeket, A", at each side of the car and securedy to such plates are two par-A allel angle rails, B1, each such rail having a liange directed toward the corresponding rail atthe opposite side of the car. Said rails are inclined from the rear toward the front between said posts, as shown by Fig. 1, and are nearly horizontal forward ot' the posts, A1. 1 liearward of the posts, A, said. rails are extended approximately horizontally any desired distancefor example, far enough to reach over a car placed behind the car, A, to receive material from the rear conveyer, B. l`he adjacent rails, B1, are joined to each other by binding plates, B1, in any desired manner, as by rivets or bolts. For the purpose of imparting greaterfstability to said rails, any desired number of cross-bars, B3 (Figs. 11 and 11), may joinl one ot' said rails at one side to another otl said rails at the other side of the conveyer.

At each sit` e of the ear a brace rod, A10, extends from the upper end of the adjacent `rear post, A, forward and downward to the side member, A4, and at eachwside ot' the vcar a similar brace rudy-'111, extends from the upper end of the adjacent post, A1, obliquely rearward and downward to saidside meniber. And at each side of the car, a tie rod, A12 extends from the pnst, A, to the post, A1. ifY-bridge-piece, the upper ends of the posts, A1, and 'forms a seat for a windlafs to be hereinafter described. From the upper end oeach post, A, a tie rod, A,

extends rearward and is joined by its rear end to the rearmost binding plate, B1.`

. In bearings, B4, in the rearmost binding plates, B1', is mounted a transverse shaft, B1, having sprocket wheels, li", adjacent the inner side of each lateral pair of angle rails, B1. 1n the binding platesI at the troni'. ends or" said angle lails are b ali-ings, B1, in which rests a transverse shaft, BS, having a sprocket wheel, B, adjacentv each lateral pair ot' angle rails, and projecting through one of said bearings and there supporting a sprocket wheel, I 11. The endless apron, B11, of the conveyer surrounds the sprocket wheels, B" and B, and its edges rest upon the inward-directed tlanges ot the 'angle rails, B1, and slide thereon` when said apron rl`he two front posts, A1, are

is driven.. On the upper angle rails, B1, are placed short oblique standards, B11, which support sloping side plates or boards, B13, at each side of the apron, B11. Said apron and said boards together constitute a trough, of which the apron is a traveling bottom. l Said angle rails, B1, binding plates, B2, 1 apron, B11, side boards, B1, and the other accessories mentioned in connection with said parts are to be regarded as together constituting the conveyer, B. For the driving of said conveyer apron, a sprocket chain, F1", engages the sprocket wheel, B10, on the shat't, BS, at the front end of said conveyer and extends thence around a sprocket wheel, F1', on the countershatt, F8.

On the motor axle, F1, is a pinion, F2,

mnntershaft, F, resting in bearings, F5. Un said eountershaft, F1, is a spur gear wheel, F11, which meshes with a spur gea-r wheel, F1, on the second countershaft, F s,

mir-sting in bearings, A15, in standards, A16,

r nig from the side members, A4, of the trame. By this means motion is imparted to said second countershaft, F5. second countershaft is a clutch, F10, adapted to engage the loose sprocket wheel, F9. Said clutch is controlled by the clutch arm, F11,

1311, having one end resting in the bearing, F13, and having the other end joined to a crank arm, F14, on a rock-shaft, F11, which r-:stsin bearings, F11, and which supports a hand lever. F11. By the setting ot' said clutch, F1,"into engagement by the shifting` oi said hand lever, F11, motion is imparted from the motor, F, to the conveyer aprpn, 'ljvowidlers, F1, are supported by a bracket, F1 in proper position to adapt said idlers to support the chain, F111, approximately inidway between the sprocket wheels, B111 and F11. 5

Between the posts, A1, and immediately above the level ot' the side members of the trarne a horizontal gear segment, C5, seeared to the adjacent cross frame member, by means ot' a king-bolt, C2, extending through an aperture, G1, in said member, '1 and through au aperture, C, in` said segment, and having at its upper end-a washer, C3, and a nut., C1. Said segment is adapted to partially rotate upon said kingbolt attrr the manner ot' the rotation et al turn-table. At each side, said segment is extended forward to form an earfUT'. .which is apertured horizontally and transversely to .the length ot' the machine. A shaft or holt, CS. extends through said ears. To saidshaft the jib is hinged for up and dow'n movement.

rl`he frame of the jib is made up as follows: C. C" are side vrails forming the basis ol said trame. Each of said rails has at its rear end a bearing, C10, through which the On said 1 and said arm is controlledby a shifting arm,

The slide blocks, E4, are reciprocated by A the outer journal, E3, on the adja-I nt endv of the bar, E1, which, as already described, rests in the slide blocks, E". By means of the reciprocation of said slide blocks, a bodily horizontal reciprocation parallel to thel length of the machine is imparted to said scoop or shovel. A partial turning movement is also imparted to the shovel, on the axis of said bar, El, during each horizontal reciprocation ofthe shovel. The mechanism for effecting such partial turning of the shovel upon said axis will be neXt described. 'l

From the forward end of each upper side rail, C", a bar, '24, extends obliquely downward and forward and is joined by its lower end to a plate, C25, which rises from the'adjacent lower side rail, C. The bar, C24, is tangential to the arc of a circle drawn from a center in the axis of the shaft, G, above described. Said bar might be curved so as to coincide with said arc; but the slight deviation between the straight line and such an arc at this point is inunaterial, as will appear further on. To the upper front face of each such bar, C, is applied a guide plate, C2G,having at its lower end a spacing arm, C27. Opposite said guide plate, (1f-"5, is another guide plate, C, resting upon said spacing arm and a space block, Cw. Bolts, C3, extend through said bars and 'bind the guide-plate, G, in position.

In each guide-way formed by the guide plates, C2G and C, is seated a slide block, E, In each of said slide blocks is a horizontal bearing, E, in which rests a journal, E, of a crank, E14. Each of said crank journals extends through the adjacent guide block and at the outer side of the latter supports a sprocket wheel, E15, to which is applied a sprocket chain, Gl, and said chain surrounds a corresponding sprocket wheel, G13, on the shaft, G11, which has already been described. By means of said chain, rotation is imparted to said cranks, El". Each of said cranks is joined to a horizontal shaft,

E16. Said shaft and said cranks are preferably joined rigidly, so that said three parts are virtually one double crank. On each side' of the forward section, E, of the scoop is a journal or wrist pm, E", to which 1s applied one end of a link or pitman rod, E13, i. the other end of which link surrounds the shaft, EN. By the rotation of said crank, PIM-Em-E, the forward portion of the shovel is raised and lowered, the axis ofthe f bar or shaft, El, forming an axis of oscillation. j,

A little way below the slide blocks, E, a horizontal guide rail, C31, is secured `to the frame'of the jib a little way Within the circle which would be described by the free end of the adjacent crank arm, E, if said guide rail were absent, and each end of the shaft, El, projects a little way beyond 'the adjacent crank arm and during` each rotation of the crank (while going through the lower portion of its orbit) engages and slides horizontally upon said guide rail, C31. Thus the lower portion of the orbit of the shaft, E, is made horizontal. When the crank engages said guide rails, C31, said crank and the guide blocks, E, are forced bodily upward, said guide block moving between the guide plates, C26 and C28, until said crank' arms assume a lposition which is perpendicular to the rails, C31. Then said cranksand' slide blocks again move downward to the lower liniit of the guide-way. On each end of the shaft, Em, is an anti-friction roller, El, which bears upon the guide ail, C.

In the lower ortion of the guide ways in which the gui e blocks are confined is a cushion, E'2,for receiving the lower end of the adjacent guide'block. Upon the rear portion of the guide rail, C31, is secured an 100 inclined guide block, E, with which the rollers, E19, engage lightly before reaclnng the horizontal guide rail, in order that the contact with the latter may be less abrupt.

The mechanisnr for reciprocating the slide 105 blocks, E, and for rotating the crank, E14-'- i Ew-E, are so timed as that the crank will move through the horizontal portion of its Y orbit simultaneously with the forward movement of the slide blocks, E4. One of the. 110 features involved in accomplishing this result is the making of the crank arms, E, and the crank on the spur gear wheel, G10, of substantially the same length and parallelv and arranging them to travel in unison.

F rom the foregoing it will be seen that during then'iovenlent of the shovel crank through the lower port-ion of its orbit, the two lines of engagement of the shovel, to-

w-it. the bar or shaft` E1 (which rests in the 120 slide blocks, E4) and the axis of the wristI pins. E, will move horizontally forward in unison, so that during such interval the entire shovel moves forward horizontally.

This movement is'indicated by arrows in 125- Fig. S.

lYhen the scoop crank leaves the guide rails, C, said crank rapidly lifts the front end of the scoop, and, at the same time, and short-ly after the beginning of such movement the 130 oi' thc/car, A.

a clutch member. Surrounding said Vshaft between said bevel gears is a slidable clutch member, F, adapted to engage either of the bevel gears, F47. A clutch arm, F1", .engages said clutch unember and is supported upon a shift rod, F 5, having` one end resting in a bearing, A25, and having its opposite end joined to the crank arm, F51,on a rock shaft, F52, resting in bearings, A26. To said shaft is connected a hand lever, F53, ad-

,jacent the hand lever, Ft. Between and in engagement with said bevel gear wheels, F *7, is a bevel gear wheel, F "'4, mounted upon a somewhat inclined, longitudinal shaft, F 55, resting in bearings, A27. O n the front end of said shaft is a worm, F 5G, which engages a worm gear, F, on a transverse horizontal shaft, F, mounted in bearings, A28. Said worm gear loosely surrounds said sha-ft and embodies a clutch member adapted to be engaged by the sliding. clutch member, F59, also surrounding said shaft and controlled by a hand lever, FG". On said shaft, F58, are two sprocket'. wheels, F61. From one of said sprocket wheels, a sprocket chain, F 2, extends to a sprocket wheel, F63, on the axle, A2, on which are. the supporting wheels, A1; and from the other of said sprocket wheels another sprocket chain, Fiz, extends to the sprocket wheel, Fm",- on the other axle, A2. By shifting said hand level', F5, the clutch, F48, is shifted for the transmission of a slow motion to the car axles for slowly moving the car to or from its work-usually for" moving it forward at a rate corresponding with the clearing of the material accomplished by the shovel in front. of the machine.

For a more rapid propulsion of the machine when it is to be moved from place to place when not working, anothermechanism is used. Qn one end of the shaft, F53, is `[ixed a` sprocket wheel, F 't, and from said sprocket wheel a sprocket chain, F, extends around a sprocket wheel, F', which loosely surrounds the shaft, l1". Adjacent said sprocket. wheel, F6, is fixed a collar, Ff", in which is an aperture, F, adapted to reg-h ister with an aperture. Fw, when the. sprocket; wheel, FW, has been turned into the proper-position. By the insertion of any suitable pin, l .lt, or shaft. F7". from the aperture, 14", into the aperture, Fm, the sprocket wheel, F, is secured rotatal'ily to said collar and through the latter to said shaft, FS, so that. motion of .said shaft is, transmitlcd'through said spri het wheel and through the sprocket chain, l'"", to the shaft, F53, and from the latter through the sprocket wheels. F, to vthe sprocket chains` Lw, und through the latter to the .sproclfat wheels, Fmt. on the car axles.
