BUCKET-TRUCK.. t

PATENT @FFIQE OE CLEVELAND, OHIO.

SPECIFICATION forming part of Letters Patent No. 369,912, dated September 13,1887.

Application filed March 5, 1887. Serial No. 229,812. (No model.)

material in the usual dump-buckets in which it is handled in hoisting and conveying ma chines without breaking bulk or breaking the package.

It frequently occurs, in the handling of coal and other material, that the contents of the buckets of the hoisting and conveying machine have to be delivered at a point at some dis tance from the line over which the tramway of the conveying-machine may be located and at some distance transversely to said line, and it has been the custom under such circumstances to discharge or dump the coal or other material from the buckets of the conveyer-machine into a truck or car, in which it would be transported and subsequently redumped at its destination.

I have designed a means to avoid the breaking of the packages by the. transportation of the usual buckets back and forth to any required distance from thehoisting and conveying machine, the means for accomplishing this end consisting, essentially in a suitable bucket truck or carriage mounted to travel on asuitable tramway or railway, and adapted not only to receive and retain in a filled condition the buckets lowered from an ordinary hoisting and conveying machine, but to also permit the dumping of said buckets,when they shall have been carried by the said truck or carriage to the desired point, by the usual mode of tilting the bucket on its trunnions.

My invention may be said to consist, essentially, in a bucket-truck adapted to receive and maintain in a proper position and to also permit the dumping of the filled buckets of any ordinary hoisting and conveying machine, and adapted to travel on a suitable tramway or railway to any desired locality, at which place the buckets carried by said truck may be discharged of their contents, all as will be hereinafter more fully described.

To enable those skilled in the art to which my invention relates to make and use the same, I will now proceed to more fully describe my improvement, referring by letters to the accompanying drawings, which form a part of this specification, and in which I have shown my invention carried out in that form which is the best now known to me, and in which I have so far successfully practiced it.

In the drawings, Figurel isa side elevation of one of my improved bucket'trucks, showing a pair of ordinary dump-buckets mounted therein, also showing a portion of the railway or tramway on which said truck is designed to travel. Fig. 2 is an end view of the same.

In both figures of the drawings the same parts will be found designated by the same letter of reference.

A and'B representtwo similar dump-buckets of any approved form or structure-such as.

are usually employed in hoisting and conveying machines for handling coal, ores, and other material-each of which is provided, as usual, with a suitable bail or handle, b, as shown, and is adapted to turn or dump about an axis of motion that is coincident with the usual trunnions to which the said bails or handles are pivoted, each set of buckets being provided, as usual, with a suitable looking or catch mechanism, the operation of which permits the oscillation ofthe buckets on the trunnions to discharge their contents.

0 0 represent the side pieces or frame (made preferably of metal) of the truck, and D D two pillow-blocks, within which are mounted the axles or trunnions c of two pairs of truckwheels, F, that run upon the rails or bearing-surfaces of the stringers or track-beams G of a suitable railway. From the framepieces or beams O O of the truck project, vertically upward, a series of posts, H, which 9 are arranged in two pairs and at such distance apart as to embrace (one between each pair) the buckets'A B, all as clearly shown by Fig. 1. Each of these posts H is forked or bifurcated at its upper end, so as to re ceive within its bifurcation and properly sup port therein a trunnion of one or another of the buckets, the extent or depth of the bifurcation in the upper end of each of said posts H being sufficient to permit the forks of the bifurcated portions of said posts to embrace laterally and hold in a vertical position the lowermost portion of one of the bails or handles of the buckets, as best seen at Fig. 2, the object and effect of the retention thus of the lowermost portion of the handle or bailinside of the bifurcated portions of the posts H being the retention of the bucket, which is locked to the bail in the proper position to prevent the escape of its contents until it shall become necessary to dump the bucket, and then to permit the dumping (by the use of the disengaging locking device) by the rotation of the trunnions of the bucket within the seat-like portions of the bifurcated parts of said-posts.

Although I have shown the truck with four posts, H, arranged in two pairs, (the adjacent posts of the two pairs being braced together, as shown by bars (1,) in order that the two buckets may be supported simultaneously upon the truck, as shown, it will be understood that my invention may be carried out with more or less advantage by the use of a truck provided with only one pair of posts, and hence adapted to support and carry at the same time only one bucket. I, however, prefer the form of truck shown, as in handling most .materials and under most circumstances it is the more convenient form of the two.

In the use of my contrivance the truck carrying, for instance, an empty bucket, such as seen at B, (which may have been recently dumped'at some remote point on the railroad or track G,) is brought up to the point for refillingby the hoisting and conveying machine, so as to receive a descending and full bucketsuch as seen, for instance, at A'. The empty bucket B is then lifted out of the posts H in which it rests, (either by slightly shifting the truck to bring said empty bucket immediately beneath the hoisting-machine or by hitching onto said empty bucket and pulling upwardly thereon,) after which the truck may be again shoved or driven off in either direction required, carrying the full bucket, which may be dumped, when the truck shall have been carried to the desired locality, by unlocking the catch mechanism and permitting the bucket to tilt on its trunnions, after which the operation of returning the empty bucket and receiving a full one may be repeated, all as will be easily understood by those skilled in theart.

It will be seen that by the use of a buckettruck substantially in the manner shown and described the material filled into the dumpbuckets of the hoisting and conveying machine may be carried off laterally from the line of travel ofsaid conveying-machine in either direction and to any extent, and may have their contents discharged into a car or boat, and by the usual tilting of the buckets at any given place without breaking the package of material from the time the buckets are filled at the receiving end-of the conveyer-machine to the time when the material may be finally discharged at some distant locality.

Of course many variations may be made in the details of construction of the truck shown and described without departing from the spirit of my invention, the gist of which lies in a bucket-truck adapted to receive and hold in proper position one or more of the buckets of a conveyermachine, and to transport said buckets in a filled condition to any desiredlocality and there permit the discharging of their contents, as described, and then return them to the conveyer-machine for reuse.

WhatI claim as my invention, and desire to secure by Letters Patent, is

A bucket-truck adapted to travel on any suitable railway and formed or provided with devices, as specified, which operate to receive the trunnions ofan ordinary hoisting and c0nveying machine dumpbucket, and to prevent the said bucket from turning on its trunnions until, its locking mechanism shall have been operated in the usual manner to effect the dumping of the load, as set forth.

In witness whereof I have hereunto set my hand this 31st day of August, 1886.

ALEXANDER E. BRO WVN.

In presence of E. T. SoovILL, CHAS. W. KELLY.
