EUGENE BIVER'I, OF CHICAGO, ILLINOIS, ASSIGNOR TO FAIRBANKS, MORSE AND COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
PlVOTED-BUCKET C ONVEYER.
SPECIFICATION forming part of Letters Patent No. 748,557 6, dated January 5, 1904.
Application filed July 29, 1902.
To all whom it may concern.-
Be it known that I, EUGENE BIVERT, a citizen of the Republic of France, and a resident of the city of Chicago, in the county of Cook' and State of Illinois, have invented certain new and useful Improvements in Pivoted- Bucket Conveyors; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to improvementsin pivoted-bucket conveyers of that class adapted to fill and to dump automatically.
The object of the invention is toprovide a construction whereby the buckets when filling form a practically continuous horizontal conveyer into which material is continuously delivered in any desired manner and whereby material may be conveyed and elevated to a predetermined point of delivery, at which point the buckets automatically dump their contents and right themselves preparatory to again refilling.
The invention embraces many novel features; and it consists in the matters hereinafter described, and'more fully pointed out and defined in the appended claims.
In the drawings, Figure 1 is a side elevation of a bucket in filling position. Fig. 2 is a similar view showing the same in its carrying position preparatory to dumping. Fig. 3 is a longitudinal section illustrating the position the bucket assumes in dumping. Fig; 4 is a top plan view of a bucket embodying my invention. Fig. 5 is a front elevation showing the bail broken away. Fig. 6 is a detail of the pivot for the bail. Fig. 7 is a section taken on line 7 7 of Fig. 5. Fig. 8 is asomewhat diagrammatic side elevation illustrating the operation of the device as a whole. Fig. 9 is a fragmentary view, in vertical longitudinal section, showing the buckets movable irom instead of toward the loader. Fig. 10 is a vertical longitudinal section of the buckets, illustrating the self-filling operation of the same. Fig. 11 is a transverse fragmentary sectionot' the upper run of the conveyer. Fig. 12 is a similar section of the lower runthereof.
Serial No. 117,471. (No model.)
As shown in said drawings, the material to be handled is coal, and a substantially horizontal trough H isprovided, along which the buckets A are drawn in filling position, while a leader I acts to deliver the material at a uniform rate into the buckets. The conveyerbuckets, as shown, are constructed of plates of metal flanged at their margins, as shown, and rigidly secured together along their meeting edges by riveting orlike means and comprise the plane side walls a, parallel with each other and between which are secured, into-- grally or otherwise, the bottom a, and the divergent walls a a The walla is extended to correspond in length with thelength of the side walla, as shown in Figs. 3 and 9, the portion 0!, thereof forming a su bst-antially horizontal bottom for the bucket when in its filling position.
On the upper end of the bucket and rigidly secured on the under side of the wall a is astrap of iron B, provided with a flange b, directed obliquely forward and outwardly from the bucket, as shown in Fig. 3, and adapted to scrape along the bottom of the trough, which 7; is provided with an upturned end and acts to scrape any material that may have fallen into the trough up into said end, where it falls back into the buckets. Flanges A, integral with side walls a, extend upwardly above the wall a and act to direct the material falling on side wall rearwardly into the next adjacent bueket. Said bucket is pivoted at a point slightly above its center of gravity when empty by means of stud-shafts or trunnions C, which, as shown, extend through the walls a. and are each provided on their inner ends I with a flange c, which is riveted to said wall. Saidtrnnnions extend through hubs d at the I lower ends D of a bail D, and a bracket 0 is riveted on the wall a of the bucket and apertured to engage the end of the trunnion outside of the hub (1, thereby acting to hold the trunnion in alinement independent of the weight of material. Journaled on theouter ends of said trunnions are the track-wheels C, on which thebucket is supported when in its filling position, as shown in Figs. 2 and 8.
The bail ends are apertured near their upper ends, as shown in Fig. 7, and stud-shafts I00 E, longer than the trunnions C, extend there- I through; Said stud-shafts at'their inner ends areintegrally connected with a bracket e, which fits closely in the bend of the bail and is riveted both to the bail end D and the horizontal portion D, as shown in Figs. 4: and 7. Journaled on each of said stud-shafts is a latch comprising a hub F, having radial arms ff, of which the arms fare provided on their outer ends on the under sides with a notch adapted to engage laterally-projecting ends F of a bar F secured on the under side of the flange or lip b. The arm f is provided at its outer extremity with a roller f adapted to engage a trip mechanism which acts to release the bucket. A spring f is engaged 011 the bail and acts to hold the arm f elevated and the armfin position to engage the bucket. Track-wheels C are journaled upon each of the stud-shafts in alinement with the trackwheels 0 on the trunnious O and, together with the track-wheels 0, act to support said bucket during the filling operation, said bail, with the track-wheels,forming atruck for that purpose. The ends of said stud-shaft beyond the track-Wheels O arejournaled transversely in carrier-chains K of any desired type, as shown in Figs. 4, 5, and 7, which provide means whereby said buckets are operated. Obviously any of the several dilferent forms of conveyor-chains may be used for the purpose. I have shown, however, a conveyor or traction chain, the subject-matter of a different invention for which application for United States Letters Patent was executed by me on the 27th day of June,1902. Said chains,
with the buckets pivoted between them, are trained over sprocket-wheels, (shown in dotted lines in Fig. 8 and indicated, respectively, by X X X*,) of which, as shown, the wheel X. is located above the sprocket-wheel X. The wheel X is located at approximately the same level as the wheel X and above the point where the buckets start upwardly after filling.
Tracks are provided on which the trackwheels 0 and O engage tosupport thebuckets in a horizontal position when filling and to support said buckets in a vertical position between the sprocket-wheels X and X when passing to a dumping position. The lower of said tracks (indicated by G) comprises anglebars secured on each side of the trough H in position to be engaged by said track-wheels and to form a rigid support therefor. Said angle-bars extend from beneath the sprocketwheel X to a point beneath the sprocketwheel X and are there upturned, as shown in Fig. 8, to directsaid buckets upwardly in a vertical position. Angle-bars g, curved concentrically with the curvature of the ends of the track-rails G, are rigidly secured one above each of said extremities to afiord engagement with said track-wheels from above and to direct the bucket to a vertical position beneath the. periphery of the sprocketwheel The lip or flange b scrapes along the bottom of the trough H, the end of which also curves upwardly. Said trough, as shown,
is lined with sheet metal approximately the same height as the curved ends of the track G and the rails g, thereby scraping material in the trough into the bucket. The rear end of said trough is inclined downwardly at g to permit the buckets to descend in a vertical position a sufficient distance for the top thereof to swing inwardly as the buckets enter the trough. Material may be delivered into said buckets while passing along said trough by any desired means. As shown, however, a loader (indicated by I, and for which application for patent was executed by me of even date herewith) is used and acts to deliver the material continuously and uniformly intosaid buckets as they pass beneath the same.
The track G supports the upper run of the conveyor between the sprocket-wheels X X on the track-wheels C as shown in Fig. 8, permitting the buckets to hang below the same on said bail. A tripper J, provided with a downwardly-curved camsurface, is supported above said track G in position for the ends of the arms or levers f to engage beneath the same as the bucket passes beneath the tripper, thereby releasing the latch and permitting the buckets to successively dump by gravity. Said buckets are so pivoted in the bail that afterdumping, the same swing upwardly and are again secured by the latches in a vertical position. Counterweights a may be secured on the bucket along the side a to aid the return.
The operation is as follows: Said buckets, pivoted, as before described, on the gudgeon or trunnious O in the ends of said bail and having the catch f securely engaged upon the projections F,are drawn along the trough, preferably oppositely from the flow of material froin the loader, and are partly filled when beneath the loader. Any material which falls upon the inclined wall a slides therefrom into the trough and the next succeeding bucket. As the buckets are drawn by the chain along said trough the extending lipb scrapes any material in the trough along to the upturned end thereof, where it falls back into the bucket as it rises to a perpendicular position preparatory to passing over the sprocket X When the bucket rights itself to a perpendicular position, the material assumes the position shown in Fig. 10, carrying the center of gravity much above the trunnious O and to the rear side of the same. The trackwheels 0 engage on the track G as the buckets pass the wheels X and the buckets supported on the bail pass along the rails to the tripper J, which may be adjusted at any point intermediate of the wheels X and X". The downwardly turned cam surface, beneath which the rolleron the ends of the arm f engages, forces the arm f upwardly and disengaging the same from the projection F on the nose of the bucket and permitting the bucket to swing downwardly, dumping its contents. When the material is delivered from the bucket, the bottom of the bucket,
being much heavier than the top, causes the same to swing backwardly until the projection F strikes the inclined end of the arm f, raising the same against the spring f and permitting said projection to pass into said notches in the extremities of said arm, thus again locking the buckets in a perpendicular position. As the buckets pass downwardly over the sprocket X and beneath the sprocket X the bottoms engage on the downwardlyinclined end g of the trough, and the continued forward movement of the top of the bucket returns the same to its horizontal position with all of the track-wheels again engaged upon the track G, in which position the bail with four track-wheels form a truck upon which the bucket is supported in filling.
While I have described my invention as preferably assembled so that the buckets move oppositely from the flow of material as it falls from the loader, this is obviously not essential, and, as shown in Fig. 9, said buckets will fill very satisfactorily if moved in the same direction with the flow of the material in the chute, the only difference being that in some instances more of the material will be deposited in the trough in the one case thanin the other. This is immaterial; however, inasmuch as the depending lip or flange b on the nose of each bucket acts to push said material along the trough, as shown in Fig. 10, until the same by gravity falls into the bucket. Obviously the buckets may be constru'cted of any desired size or in any desired manner, and any desired type of chain,tracks, rollers, trippers, or the like may be employed, and I do not desire to be limited to the exact construction'of buckets herein shown and described, inasmuch as many details of construction may be varied without departing from the principles of this invention.

latch journaled on each stud-shaft and adapted to engage on the front of the bucket carried below said truck, and track-wheels also on saidstud-shaft, said bail-truck acting to support the bucket in horizontal position in filling and to swing the same in vertical position from the foremost track wheels in dumping, and means for releasing the latch.
11. In a device of the class described the combination with a scoop-shaped bucket, of a bail in the ends of which the bucket is pivotally supported in position to stand vertically upright when empty, a downturned lip on the front end of the bucket, lateral projections thereon, a latch journaled at the top of the bail and adapted to engage said lateral projections, an arm extending oppositely from the latch, a spring engaged on the bail and pressing said arm and holding the latch in engaging position, forward and rear trackwheels on each of the 'bail sides, chains engaged to the bail adjacent to the forward track-wheels and tracks located one above the other on the lower of which the bucket is supported in horizontal position on all of the track-wheels and on the upper of which the bucket swings on the forward of said track-wheels, and a tripping device adapted to engage said arm and lift the latch to per mit the bucket to dump.
12. The combination with a scoop-shaped bucket, of a bail pivotally engaged thereon at a point which causes the bucket to tend to assume a vertically-upright position when empty, a latch on the bail acting to engage the nose of the bucket thereto, forward and rear track-wheels on each side of the bail on all of which the bucket is carried in filling position,and on the front pair of which the bucket is carried to dumping position, means for releasing the latch with the effect of causing the bucket to dump its load, then swing to avertical position and again engage the latch.
13. The combination with a conveyertrough having one end curved upwardly to approximately a vertical position, of chainconnected conveyer-buckets fitting closely in and movable toward said upturned end of the trough, means for delivering material from above into the buckets, upwardly-directed lateral flanges on each bucket acting to direct surplus material into the next adjacent bucket and a lip on the nose of each bucket acting to scrape material from the trough into the bucket.
14. The combination with a feeding device, of a trough located below the same and having one upturned end, a track above the trough, chain-connected scoop-shaped buckets each fitting closely in the trough and journaled on a truck movable on said track toward said upturned trough end, upwardlyprojecting lateral flanges on each bucket acting to direct surplus material into the next adjacent bucket, a lip on the nose of each bucket fitting closely in the bottom of the trough and an upper track along which the buckets move to dumping position supported in a vertical position on the front wheels of the truck and means for dumping the bucket-s.
In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
