BUCKET ELEVATOR.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed March 26, 1919. Serial No. 285,368.

To all whom it may concern Be it known that we, FRANCIS BENJAMIN WHILE and THOMAS OSULLIVAN, both subjects of the King of Great Britain, and both residing at Southampton, in the county of Hampshire, England, have invented new and useful Improvements in Bucket Elevators, of which the following is a specification.

This invention relates to improvements in bucket elevators for digging, lifting and transferring loose coal, grain, ore and like materials, and more especially intended for discharging 'colliers, barges and the like, and bunkering ships.

According to our invention non-tipping rigid buckets are articulated together to form in themselves an endless chain which possesses great rigidity with flexibility in working.

ging as well as lifting loose coal and other heavy materials which cannot be satisfactorily done with buckets that are attached to an endless belt. The hinges of the buckets engage with recesses in the'driving wheel and constitute a good driving connection which avoids slip. The buckets are further so constructed that the rear wall and rear wardly extended sides of each bucket c011- stitute a chute down which the materials from the succeeding bucket 1n the series as the latter bucket passes over the top wheelof the ladder, are discharged, clear of the bucket ladder.

Any suitable or convenient means may be provided for supporting the bucket ladder and for adjusting it vertically and horizontally. A suitable means for this purpose is hereinafter described.

Referringto the accompanying drawing,-

which illustrates our invention:

. Figure 1 is a central vertical section of a p This construction of bucket lad-* der enables the buckets to be used for dig frame 13 of any usual or suitable type, and an endless chain of buckets C, C mounted on said wheels. Each bucket C is a rigid structu're formed by a front wall 1, a rear wall 2 and side walls 3, 3. The rear wall 2 and side walls 3, 3 are extended beyond the receptacle part proper of the bucket, as shown at l and 5 respectively, and further the side walls are extended rearwardly beyond the rear wall 2 forming wings 6, 6. Each bucket is moreover constructed with a hinge l1ke connection 7, at each end, so that the several buckets may be articulated together by pins 8, 8 to form an endless chain of buckets. The side wings 6, 6 of each bucket are inset at their rear extremities as shown at 9, 9, Fig. 2, so as to fit between the side walls of the next-succeeding bucket. The inclination of the front and rear walls 1, 2 is such that when'the chain of buckets is mountedon the wheels A, A of the ladder, the outer face of the rear wall of each bucket is in line with the inner face of the front wall of the following bucket when these buckets are passing over the wheel A. This will be readily seen from an inspection of Fig. 1. The hinges of the buckets when.

passing over the driving wheel A engage with transverse recesses 1a in the face of said wheel andthus insure a good driving connection which avoids slip.

Referring to Fig. 3, D is a standard which may rest on a quay wall, or floating deck. E is an arm one end of which is pivotally mounted on the standard and prefer ably adjustable c. g. in a bracket F on said standard, and the other end of which is adjustably supported by ropes G passing around a pulley H. The frame 13 of the bucket ladder is suspended from the outer end of the arm E. The arm E may be connected to the frame of the bucket ladder at its upper end or at'a point substantially below the upper end of the frame. Another arm J pivotally connected to the standard carries block K which is connected to an intermediate part of the frame B and which can slide in a slot L in the arm J. An endless chain or rope M passing around pulleys N, O is connected to the block K. Bymoving this chain or rope the position of the lower end of the bucket ladder can be adjusted as required. 1 is a motor supplying the power for driving the buckets, through driving chains Q, R, S, for raising and lowering the arm E through driving chains T, V, and for adjusting the position of the bucket ladder through the chain or rope WI. The motor is shown at the foot of the standard, but it may be mounted on the standard itself at any suitable part thereof. W is a barge from which materials are to be discharged and Y is a vessel to be loaded. 10 is the upper part of a chute carried by the frame of the bucket ladder and open at the side facing the buckets on the delivery side of the top wheel A. Into this chute the materials are discharged from the buckets. 11, 11 are guide plates fixed in the chute and 12 is a flexible extension of the chute. Preferably the wheels A, A are flanged at 13 to prevent the buckets moving laterally on the wheels.

What we claim is 1. In a bucket elevator for digging, lifting and transferring pulverulent, granular and lumpy material, a series of buckets each having an extension of its rear wall prolonged beyond the receptacle portion thereof, and hinge connections between the said extension of the rear wall of each bucket and the front wall of the succeeding bucket.

2. In a bucket elevator for digging, lifting and transferring pulverulent, granular and lumpy material, a series of buckets each having extensions of its rear and side walls prolonged beyond the receptacle portion thereof, and hinge connections between the said extension of the rear wall of each bucket and the front wall of the succeeding bucket. Y

3. In a bucket elevator for digging, lift- I and lumpy material, a series of buckets each comprising front and rear walls, said rear walls each having an extension beyond the receptacle part thereof, hinge connections between the rear wall extension of each bucket and the front wall of the succeeding bucket to form an endless chain of said buckets, and'a wheel over which the said chain passes, the hinge connections protruding only on that face of the chain or buckets which is toward the wheel so that each rear wall extension forms a closely adjacent continuation of the front wall of the succeeding bucket as the buckets pass around the said wheel.

5. In a bucket elevator for digging, lifting and transferring pulverulent, granular and lumpy material, a series of buckets forming an endless chain, the rear wall of each bucket having an extension, a hinge connection between an extension of the rear wall of each bucket and the front wall of the succeeding bucket, the side walls of the buckets having extensions beyond the receptacle parts thereof, a wheel around which the said chain passes, said wheel having re cesses to receive the hinge connections as they pass around the wheel, and flanges on said wheel intermediate said recesses to prevent lateral movement of the buckets on said wheels.

6. In a bucket elevator for digging, lifting and transferringpulverulent, granular and lumpy material, a series of buckets each having an extension of its rear wall prolonged beyond the receptacle portion thereof, hinge connections between the said extension of the rear wall of each bucket and the front wall of the succeeding bucket, a ladder frame, wheels around which the buckets passat the upper and lower ends of the said ladder frame, a standard, an arm on which the upper end of the ladder frame is pivotally supported and which is pivotally supported on the said standard, a second arm pivoted to the'standard and a block movable along the said second arm and having a pivotal connection to the ladder frame at an intermediate part thereof.

7. In a bucket elevator for digging, lifting and transferring pulverulent, granular and lumpy material, a series of buckets each having an extension of its rear wall prolonged beyond the receptacle portion thereof, hinge connections between the said extension of the rear wall of each bucket and the front wall of the succeeding bucket, a ladder frame, wheels around which the buckets pass at the upper and lower ends of the said ladder frame, a standard, a bracket on the said standard, an arm on which the upper end of the ladder frame is pivotally supported and which has an adjustable pivotal support on the said bracket, a second arm pivoted to the standard, and a block movable along the said second arm and having a pivotal connection to the ladder-frame at an intermediate part thereof.
