To all whom it may concern;

Be it known that I, FRANCIS H. \Vnnns, a citizen of the United States, and a resident of the city of New York, county of Bronx, and State of New York, have in vented an Improvement in Hoisting Buckets, of which the following is a specification. 1

My invention relates to improvements in hoisting buckets of the kind used to hoist coal or other loose divided material, and my invention is intended primarily to produce a simple and convenient bucket whlch is particularly adapted for use in the holds of vessels, or other places, where the material is hoisted through a hatchway or the like, and where it is necessaryto move the bucket from the direct hoisting line to one side to fill it prior to hoisting. Bucket-s i for the purpose outlined above must necessarilybe adapted to carry the work forward rapidly, as it is necessary to unload vessels with great s eed, and the bucket must be so shaped t at it will occupy no unnecessary space, and of such a height that it will carry a heavy load and still not necessitate lifting the shovelfulls to fill it too high, as this tires the men too much. It is also desirable to construct the bucket so that it can be easily portable, and so that when dumped it will not break up the coal or other materials to any great extent. the bucket constructed so that it can be detached readily from the hoisting line and moved'to the place where it isto be filled. The buckets generally used for the purpose stated are cumbersome, heavy, and usually mounted on wheels. Because of their size and weight, it takes two men to handle them comfortably, and owing to their construction they vcannot be made to oarry more than agrelatively small load, which is a serious handicap in quickly hoisting a large amount of material. Furthermore, they are so high that a good deal of energy is expended in shovelling the material into them, and when dumped they break the material up seriously if it is at all friable.

My invention is intended to overcome the above and other difliculties, and produce a simple bucket which will fulfill the requirements as nearly as possible, and my chief effort has been to produce a bucket It is also desirable to have which will fulfill the necessary conditions, and will still be cheap and sim le. In line with this idea I have proc need a bucket which is readily detachable from the hoisting hook or line, and made it comparatively low and of cylindrical shape, so that one operator can turn the bucket on its side and quickly roll it to the place where it is to be filled. Because of this construction it is also possible to make the bucket of less weight than the usual bucket, and still be capable of carrying three or four times as much material, and an operator can easily tip the bucket up and roll it to place, even if it be of the large size indicated. This action is facilitated by having the hoisting bail and dumping line readily separable, and the manner inwhich these parts are attached to the bucket also facilitates its easy dumping. All of which will appear more clearly from the description which follows.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a side elevation of the filled bucket ready for hoisting.

Figure 2 is a side elevation of the bucket .is an important feature where buckets are to be used for the purposes above stated. To give it the necessary strength and still keep it cheap, I preferably attach a rim 11 of angle iron or other reinforcement at the top edge.

The bucket is provided at the top with a flexible hoisting bail l8, and it will be noted that this is hung off the centre as shown at 14 in Figures 1 and 2. For dumping and hoisting purposes I also use a line 15 which is attached to the bottom, and which can be conveniently threaded through holes 16, 17 or 18 in the reinforcing strip 19, and arranged at right angles to the plane of the swing of the bail 13, and the line 15, which like the bail 13 can be a cable, chain, or the like, is provided with a terminal loop 20 to engage the hoisting hook 21 which is attached to the line 22.

hen the bucket is filled, which can be easily done because it is compact and can be made low and still capable of carrying a large load, the line 15 is drawn upward and inward over the side and top of the bucket, and together with the bail 13 attached to the hoisting hook and the bucket can then be raised evenly. The length of the line 15 should be such as to cause the bail 13 and loop 2 to DlOOtdll the hook at substantially a line above the centre of the bucket. 'hen the bucket is to be dumped. the line is slacked, the bail l3 detached from the hook, and the line then raised and this causes the bucket to tip over generally as shown in Figure 2, and to be drawn away from the pile so as not to drop the material any great distance, and thus a great deal of breakage is obviated. Sometimes I make the bail 13 with a third leg 13, as shown by dotted lines in Figure 1, which is connected with the bucket midway between the parts l t, as this enables the bucket to be carried more steadily, and the dumping line 15 can be used just the same as indicated.

lVhen the bucket is dropped into the hold of a vessel or similar place, if a part of the coal or other material has been removed so as to leave the pile a little distance from the hoisting hatch or opening, the bail 13 and line 15 are detached from the hook, and the bucket is turned quickly on its side as shown in Figures, and rolled to the place where it is to be filled. It will be seen how much easier and quicker this is than for two or more men to lug the usual type of bucket on wheels. and it will also be seen that as the bucket is readily detached from thehoisting parts, it can be handled much easier than if the hoisting line had to be pulled along with tachability, adaptability, and ease of handling, which I have hereinabove described.

By making the bucket so simple and so easy to handle, I greatly increase the speed of discharging a vessel, and effect a great economy of material where it is friable, as my bucket breaks the material less, and the finely divided material is usually of far less value than where it is whole.

I refer to the cylindrical bucket and I prefer this type on account of its easy rolling, but obviously the sides may be more or less flaring if desired without affecting the invention.

1. A fiat bottomed c \;'lin :lrical hoisting bucket having a bail at the top hung off the centre of the bucket, a dumping line at the bottomarranged to extend over the side and top of the bucket to meet the bail an'd detachably connect with a hoisting hook, and means for attaching the dumping line in different places across the bucket bottom.

2. A hoisting bucket of substantially cylindrical shape and provided with a flat bottom, a flexible bail secured to said bucket near the upper edge thereof and off the cen ter of said bucket, a reinforcing element secured to the bottom of said bucket, a dumping line secured to said reinforcing element and extending over the side and top of said bucket, and together with the bail serving to support said bucket, the upper endsrof the bail and dumping line making a separable connection with ahoisting hook.

3. A hoisting bucket of substantially cylindrical shape and provided'with a flat bottom, a flexible bail secured to said bucket near the upper edge thereof and off the center of said bucket, a reinforcing element secured to the bottom of said bucketat substantially right angles to the plane of the bail, a dumping line secured to said reinforcing element and extending over the side and'top of said'bucket, means in said reinforcing element for securing the dumping line thereto in any one of a. plurality of positions, said bail and dumping line serving to support saidbucket, the upper ends of the bail and dumping line making a separable connection with a hoisting hook.

In testimony whereof, I have signed my name to this specification this 12th day of May, 192%.
