DREDGlNG-BUCKET.

SIECIFIGATION forming part of Letters Patent No. 546,698, dated September 24, 1895. Application filed January 28, 1895- Serial No. 536,755- (No model.) I

To aZZ whom it may concern: 7

Be it known that I, ELIJA JOHN FADER, miner, residing at the town of Calgary, in the district of Alberta, in the Northwest Territories, in the Dominion of Canada, have invented a certain new and useful Dredging- Bucket; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being made to the accompanying drawings, in which Figure 1 is a plan of bucket, longitudinally. Fig. 2 is a plan of bucket in operation on a river-section embodying my invention.

The first part of my invention relates to the bucket and its construction in such a manner that in a river-current, with the aid of certain cables, it will swing out into the stream automatically, having propeller-flanges attachable for lighter currents and reversible, so that it can be worked from either bank of a river or stream. It also has a funnel-shaped month, which on being drawn by that end ashore dips and forces its way into the riverbed, thus filling the bucket with the material scraped from the bed of river, this funnelshaped mouth to have teeth or sharp spikes bolted on when necessary in working on a hard-clay strata. Bucket-barrel and funnelfiange are each made in two pieces and bolted together, so that the whole can be taken apart and packed on horses to transport across mountainous country. It also has a bottom with hinge and spring latch, so that when hoisted its contents can be emptied by knocking open the latch.

The second part of my invention relates to the method of working thisbucket from either bank of a river by attaching to the swivel at the end of draw-irons at the mouth or open end of bucket a hook and pulley, through which works a cable having one end securely fastened on shore and the other end working in a winch on same shore. To a' swivel on the other or bottom end of bucket is attached a rope or cable fastened to the opposite shore or anchor out in the stream, it more suitable, and of sufficient length to allow the bucket to be hauled ashore and emptied, making use of the river-current acting on the bucket-propeller flanges and last-mentioned rope or cable to give to the bucket a revolving progressive motion over the bottom or bed of river, swinging it out from shore in to position, and to hold it against bed of river as it is drawn ashore by winch.

In Fig. 1 of drawings, A is the barrel or bucket, of cylindrical form, three feet long, with a diameter of two feet four inches, made of roll-plate, steel, iron, or aluminium, in two sections, bolted together, as shown at I I and at opposite side of barrel. B is the funnelshaped dipping-flange, made in two sections and bolted together, having a width of ten inches, a diameter at outer edge of three feet, and inner edge bolted to one end of barrel A. O is the bottom at the other end of barrel, opening with a hinge on barrel opposite the spring-latch K, which fastens the bottom when closed. G is a swivel-ring on bottom for attaching cable. D D D are the propellerflanges, bolted to bucket by braces H H H. Each of these flanges encircles one-third of circumference of barrel,are four inches wide near end at B, and eight inches wide at end at 0. They can be reversed to L L and bolted to barrel, so that bucket can be worked from either side of river. E E E are the draw-irons, three feet long and one inch thick, bolted to barrel inside of funnel or dippingflange B, having a swivel-ring F at outer end for attaching cable.

Fig. 2 of the drawings represents a section of river with current running in the direction as shown by arrow, and shows the method of working the bucket II. At A it is being swung out from shore O D to its position at B, when it is ready to be drawn ashore by the cable E F on the pulley I, one end fastened at M and the other wound on winch G. K is the rope or cable fastened on shore at L and to rear or bottom end of bucket, on which it swings out into the stream by paying out the cable E F. If necessary, the cable K can be supported by one or more buoys or lighters, and should the bucket foul on a bowlder or other obstruction it can be relieved by attaching end of cable at M to thelighter N, and by means of the winch G running out the lighter N to the bucket. This failing, bucket can be relieved by the cable K. After bucket is hauled ashore it can be hoisted into position over sluice-box P by means of asnatch-block V foo on triangle 0, and bottom of bucket thrown open by knocking up the latch.

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

1. A dredging bucket of cylindrical form with or without the propeller flanges D, D,D,

which are required only in slack currents,

shore at M, working through pulley I and the other end to winch G which hauls bucket ashore, and with the cable K one end of which is fastened on opposite shore at L or to an anchor out in the stream and the otherend to swivel ring on bottom of bucket when by paying out the cable E, F the river current acting on cable K and on bucket revolves and swings the bucket out into position ready to be filled and drawn ashore, substantially as and for the purpose hereinbefore set forth.
