To all whom 'it may concern:

Be it known that l, HUGO VELTEN, sub-4 residing at No.

The present invention refers to conveyers which are designed to transport lumps of any material or any material in pulverulent, granular, liquid or semiliquid state along a path either horizontal or gradient, either ascendant or descendant, either straight or curved. A series of buckets are journaled on supporting beams, which extend all along the path. Each of -said buckets, on being raised by causing turn around its journals, discharges its contents into the adjacent bucket.

The arrangement is such: 1st that each in the Kingof the buckets \is alternately raised when it discharges its contents into the next foll lowing one and lowered when it receives the contents of the preceding one. 2nd that if the v bucket-s are numbered in the ordinary course beginning from the ,driving shaft towa'rd the end of the apparatus, 4the buckets1 bearing an odd number are raised just at 'the moment when the buckets, bearing an even number,.are being 'lowered and vice versa.

In the accompanying drawings: Figure 1 is a side elevation of my conveyer, partly in section; the buckets being shown in their middle position; Fig. 2 is a plan from above of Fig. l; Fig. 3 is a side elevation partly in section in which the Odd numbered buckets are at the end of their upward stroke and the even numberedbuckets at the end of their downward stroke; Fig. 4 is a top plan view of a conveyer extending' along a circular path; Fig. 5 is a part-sectional side elevation of an inclined conveyer `for raising the material; Fig. 6 is a diagrammatic sectional view, tion of the rear wall of a bucket; and Fig. 7 isa fragmental sectional-view of a pair of buckets equipped with iiap valves.

On each of the buckets are riveted two levers, namely 11, 12 and res ectively 21 22, 31 32, 41 42 each of which 1s journaled on one of the supporting beams a, b.

On the driving shaftyc two disk cranks d1 d2 are keyed, having their pins e1 ez shifted by 180 with respect .to each other. The connecting rod f1 journaled 0n the piu and useful showing the construce1 actuates the coupling rod 1 on which are journaled the levers 21, 41o the even numbered buckets, while the connecting rod f2 journaled on the pin e2, at the opposite end of thev driving shaft, actuates the coupling arod g2, which is connected to the levers 12,' 32 of the odd numbered buckets.

Fig. -3 clearly shows the mode of operation of the apparatus. i

If the number of revolutions be roperly rial to be conveyed ressed against the boitt-om and rear wall o? the bucket up to about the end of the upward stroke, when the action of gravity causes the same to glide down into the adjacent bucket, which has meanwhile reached the downward end of the stroke.

ln'order to get buckets of the greatest chosen, the centrifugal force keeps t .e mateossible storage capacity for a gi von distance etween the journalsand a given width between the supporting beams, -tho edges, along which the discharge from the buckets takes place, are' rcferably situated between the centers of tlc corresponding journals and the rear walls of the buckets themselves; an arrangement which allows of the said dischargeedge being overlapped by therear edge of the adjacent bucket (see the recess k1, h2 at the front of bucket 4 (Fig. 2).)

The position of journals is always to be chosen in such a way as to cause the buckets to give rise to a momentum bringing forth simple tensile stresses in all parts of the apparatus, whereby the bad iniuence of play is removed and a quiet noiseless running secured.

Fig. 4 shows my conveyer as applied to a transport along a circular path, when the axes. of all journals will have to converge toward the center of the circle.

Fig. 5 is a diagram referring to the case in which the material is to be conveyed along a slope of'45.

It will be observed that the rear wall of each bucket has a curvature which is less than the curve lv, z, (Fig. 6), described with the pivot axis as a center and the distance from said axis to the lower edge of the rear may be advisable to provide the buckets with flap valves which are shown in their. end

'for drying or washing materials, chemical products, animal or vegetable substances of' diierent descriptions.

how the same is performed, what I claim is:

1. In a conveyer of the character set forth, the combination with a plurality of pivotally mounted buckets having front discharge ends, of automatically opening valves controlling said ends, and means for-swinging the alternate buckets in opposite directions to cause the delivery of material from one to another.

2. In a conveyer of the character described, the-combination with a plurality of ivotally mounted buckets, havlng front disc arge ends, of forwardly and automatically opening flap valves pivoted at their upper ends tothe buckets, and havingA free lower ends, and means for swinging 'alternate buckets in opposite directions to cause the delivery of material from' one bucket to the next.

3. In a conveyer of the character described, a plurality. of. swinging conveylng 'buckets having open'tops ,toreceive the material and having discharge ends and outwardly opening means mounted on the discharge end of each bucket for preventing a premature falling of the material out of the buckets.

4. A conveyer of the class specified comprising, in combination, a pair of spaced, parallel supports provided, each, with a series of pivots, a series of buckets disposed between said supports, a pair of bell-crank levers associated with each bucket and disposed upon the opposite sides thereof, each lever bein pivoted at its apex to one of said I j pivots an having one of its arms fastened 'Having thus descrlbed my lnventlon' and to the corresponding bucket, and devices respectively connected to the other arms of the levers of alternate buckets for swinging said alternate buckets in opposite directions and alternately delivering material 4from one bucket to the next.

5. A conveyer of the class specified comprising, in combination,l a pair of spaced', parallel supports provided, each, with a series of pivots, a series of buckets disposed between saidv supports, a pair of bell-crank levers disposed upon oppo'site sides of each bucket and having, each, one arm secured thereto, each lever being pivoted at its apex' o one'of said pivots, a pair of connecting rods to which the other arms of alternate buckets are connected, and means for reciproeating said rods simultaneously in opposite directions, to swingv said alternate buckets in opposite directions and alternately deliver material from one bucket to the next.

In testimony whereof I hereunto aiix my signature in the presence of two witnesses. i HUGO WELTEN. Witnessees:
