CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 570,876,6lated November 3, 1896.

Application filed July 9, 1895. Serial No. 555,385. (No modeld To all whom, it may concern:

Be it known that I, AUGUSTUS L. LE GRAND, a citizen of the United States,residing at Pittston, in the county of Luzerne and State of Pennsylvania, have invented a new and usep ful Conveying Apparatus, o f which the folapparatus.

Y sprocket-wheel for driving the same.

lowing is a specification.

This invention relates to conveying apparatus; and it has for its object to provide an improved swinging or laterally-ad j ustable apparatus of this character designed for removing and screening material from culm-banks, sand-banks, and the like, and, as the banks are removed, to be adjusted toward the embankment without disarranging the driving or operating mechanism for the conveyer.

The invention also contemplates, as a special .feature thereof, means for screening the material, so that the ne and coarse material will be conveyed in different directions or. to different points of deposit, and in this ad aptation of the apparatus the same is especially useful in connection with sand banks to screen the sand from the gravel and in connection with anthracite-onlin banks to screen the rock, slate, and larger particles from the finer particles of the bank.

With these and other objects in view,which will readily appear as the nature of the invention'is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings, Figure l is a top plan View of a conveying apparatus constructed in accordance with this invention, shownas arranged in operative relation to a culm or sand bank. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged detail side elevation, partly in section, of a portion of the Fig. 4 is an enlarged detail vertical sectional view on the line 4 4 of Fig. 3. Fig. 5 is a plan view of the turn-table. Fig. Gis an enlarged detail elevation of a short section of the tlighted conveyer and the` Fig. 7 is an enlarged detail transverse sectional view on the line 7 of Fig. 3. Fig. Sis an enlarged detail sectional View showing a modied construction of pivotal support for one end of the conveyer-frame. Fig. 9 is an enlarged detail sectional View of the turn-table.

Referring to the accompanying drawings, 1 designates a laterally or horizontallyswinging horizontal conveyer-frame built in any suitablelength, according to the size of embankment in connection with which the same is designed to be employed. The frame l is referred to as being a horizontal frame and adapted to swing in a horizontal direction, and in this connection it will be understood that when the apparatus is used on perfectly level ground or on a level surface the same will then be truly horizontal and will swing horizontally toward the embankment from which the material is being taken, but in use the apparatus will necessarily be employed at times on uneven surfaces and even on declivities. In such cases the conveyer-frame l and the movement thereof laterally will be approximately horizontal, and therefore the term horizontal is to be understood, in a relative way,with reference to the use of the apparatus as working directly over the surface of the ground irrespective of the level thereof. The said laterally or horizontally swinging conveyer-frame l supports therein a pair of horizontal upper and lower conveyer-troughs 2 and 3, respectively, which extend from end to end of the conveyer-frame. The upper and lower conveyer-troughs 2 and 3 are arranged one directly above the other and extend in parallel planes, so as to operate in conjunction with each other for the purpose of receiving different portions of the material to be conveyed to a point of deposit, as will be particularly referred to. Both of the conveyer-troughs, which extend the entire length of the swinging conveyerframe, are open at the top and are provided with opposite inclined sides 4, and the upper of said conveyer troughs, 2, is provided throughout the length thereof with screensections or a series of screen-bars 5, which allow the liner portions of the material, which is shoveled into the upper trough, to screen or sieve through the said upper trough and into the lower trough 3, which is provided with a closed bottom, sovthat the finer portions of the material may be conveyed through the IOO ' the pivoted end of the conveyer-frame.

lower trough 3 in one direction, while the coarser portion of the material is conveyed through the upper trough 2 in an opposite direction to a separate point of deposit.

The horizontally or laterally swinging conveyer-frame 1 has fitted to the lower side thereof at suitable points supporting-rollers 6, which are arranged to travel on the trackrails 7, arranged below the conveyer-frame, and providing means, in conjunction with the supporting-rollers, to permit the conveyerframe to be freely swung toward the embankment as the same decreases in size. The frame lis also provided at one extremity with the lateral extensions or timbers 8, that are rigidly fastened on top of the rotary turntable plate 9. The rotary turn-table plate 9 is supported for a fixed rotation on the stationary bearing-plate 10, which is mounted on a stationary supporting base-frame 1l, which base-frame provides a firm support for The said stationary bearing-plate l0 is provided with a circular bearing-iiange 12, which fits at its upper edge inside of the short depending rim or flange 13, formed at the periphery of the rotary turn-table plate 9, and providing means to assist in holding the plate 9 perfectly steady in its rotation. The bearing-plate l0 is provided on its upper side with a circular bottom track 14, on which travel the vertically arranged supporting wheels or rollers 15, mounted in the bearingbrackets 16, fastened to the underside of the rotary turn-table plate 9, and on the inner side of yits upwardly-disposed flange 12 the plate 10 is also provided with a circular side track 16, against which travel the horizontally disposed side Wheels or rollers 17, mounted in the bearing-brackets 18, secured to the under side of the plate 9, near its edge. The rollers 15 and 17 provide for the free pivotal support of the plate 9, and also for the iirm bracing thereof, so that the plate will freely rotate in a fixed circular plane.

The rotary turn-table plate 9 is provided centrally on its upper side with a bearing-step 19, in which rotates the lower end of the vertical pivot-shaf t 20. The vertical pivot-shaft 20 has itted on the upper end thereof the horizontal beveled gear-wheel 21, which meshes with a beveled gear-pinion 22, mounted on one end of the drive-shaft 23, which is driven by means of suitable belting to provide for transmitting motion to the vert-ical pivotshaft 20. The said vertical pivot-shaft 2O has tted thereon directly above the bearing-step 19 a horizontal beveled gear-pinion 24, with which meshes a vertically-disposed beveled gear-wheel 25, `titted on one end of the horizontal headshaft 26. The horizontal headshaft 26 is mounted in suitable bearings 27 on the conveyer-frame 1 ,at the pivoted end thereof, so that as said conveyer-frame is swung laterally the beveled gear-wheel 25 will always maintain its engagement with the pinion 24, which transmits motion thereto, and

the said head-shaft 26 has mounted centrally thereon a vertically-disposed sprocket-wheel 28, over which passes an ordinary link belt or conveyer-chain 29. The conveyer-chain 29 extends the entire length of the conveyerframe 1, and at the end of the frame 1, opposite the wheel 2S, the said chain passes over an idler chain or foot wheel 30, iitted on the foot-shaft 31, mounted in suitable bearings at the unpivoted or swinging end of the conveyer-frame l. The upper horizontal portion of the conveyer-chain 29 runs in one direc tion in the upper trough 2, and the lower horizontal portion of the conveyer-chain runs in an opposite direction in the lower trough 3, and fitted on the conveyer-chain 29 at regularly-spaced intervals are a series of conveyen flights 32, which travel directly on the bottom of the troughs 2 and and provide means for pushing or conveying the material in the troughs to one end thereof.

Through the medium of the gearing described motion is transmitted to theendless conveyer consisting of t-he chain 29 and the flights 32, and in operating the apparatus the conveyer-troughs are swung to a position directly adjacent to the bank of material, and the material is then shoveled into the upper trough. The screen-sections of the upper trough allow the finer portion of the material to fall into the lower trough, so that the coarse material will be conveyed through the upper trough in one direction and the finer material will be conveyed through the lower trough in an opposite direction. The coarse material which remains in the upper trough 2 is carried toward the foot-wheel 30, and when it reaches a point directly adjacent to said wheel it discharges through a laterally-extending chute 33, communicating with the upper trough 2 and extending to a point over a supplemental conveyer 34. This supplemental conveyer 34 is arranged at one side of the swinging end of the conveyer-frame 1 and may be of any suitable construction for conveying away the material discharged from the upper trough 2. Vhen a culm-bank is being removed through the medium of the herein-described apparatus, the coarse material discharged from t-he trough 2 is carried by the supplemental conveyer 34 to a breaker, Where .it is crushed, washed, and the coal separated from the slate, while the iine portion of the material which falls into the lower trough 3 is conveyed through the lower tro ugh toward the pivoted or fulcrumed end of the conveyer frame, at which point the said lower trough has leading off from the bottom thereof a downwardlyinclined chute 35, which extends over the lower end of a supplemental inclined conveyer 36. veyer 36 is arranged to extend at an inclination beyond the pivoted or fulcrumed end of the conveyer-frame, and when the apparatus is employed for conveying onlin the fine portions of material discharged from the trough 3 onto the conveyer 36 are carried by such The con- K IOO IIO

conveyer to the boiler-house, where it is used for fuel, and it will therefore be seen that the purpose of the conveyers 34 and 3G is to con.- vey the separate portions of the material to 'separate points of deposit.

The apparatus herein described is susceptible of modification, such as illustrated in Fig. S of the drawings, in which figure the rotary turn-table plate` 9a is illustrated as being provided centrally on its under side with a rounded pivot-stud 37, turning in a bearingsocket 3S, formed in the upper side of the step-block 39, suitably secured on a stationarysupporting base-frame l1. 4At this point v latches 42 with the catches 43 the drop-doors 4l will be supported in theirclosed position, so as to prevent the material from screening through the screen-sections into the lower trough 3, in order that all the material can be conveyed through the upper trough in the direction traveled by the upper iiights of the conveyer. When it is desired to use both troughs, as described, the doors 4l are unlocked and allowed to drop down to uncover the openings in which the screen sections or bars 5 are fitted, and in the event of it being desired to convey all the material in the direction traveled by the lower flights of the conveyer the material is all shoveled or otherwise mechanically placed into the lower trough, as will be readily understood.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
