LOADING AND HOIYSITING BUCKET.

SPECIFICATION forming part of Letters Patent No. 402,134, dated April 30, 1889.

Application filed January 30, 1889. Serial No. 298,139. (No model.)

To all whom it may concern.-

Be 1t known that I, WALTER S. BOGLE, a

citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Self-Loading Hoisting-Buckets, of which the following is a specification.

My invention relates to a hoisting-bucket for use in transferring coal from the pile in docks orsheds to another part of the premises-as, forexample, where the coal is first hoisted in a bucket, and the bucket carried by a car moving on an elevated track to a hopper, from which cars or wagons are loaded; and the object of my invention is to construct a hoisting-bucket which shall load or fill itself by the pull of the same rope which transfers the car along the elevated track, and thereby is saved the labor of men who have heretofore been employed to fill the bucket, which has usually been done with shovels.

In the accompanying drawings, Figure 1 is a perspective -view of the bucket-filling. Fig. 1 is a side elevation of the bucket and dump. Fig. 2 is a side elevation, and Fig. 3 a rear elevation, of the bucket.

A designates the bucket, which is shown in Fig. 1 in a horizontal position, that being the position which it assumes when itis about entering the pile of coal. The coal-bucket, preferably, has straight side walls, which are designated a a, and a bottom wall, a, which is rounded off toward the rear, so that the bucket will freely slide down the pile of coal. A portion of this bottom wall, toward the opening of the bucket, is straight, to adapt it to conform to the floor or surface 011 which the coal is piled.

A hinged door, 13, is provided in the bucket, so that when the latter assumes its vertical position, as shown in Fig. 2, the door will be at. the lower side thereof. This door will have suitable provisions for locking it-as, for example, the bolts 19 b, which are connected by chains b b, or other suitabledevices to the rock-shaft D; and this rock-shaft will have a rocking arm or lever, E, preferably provided with an anti-friction roller, 6, which will be adapted to engage a suitable fixed stop, located at the point where it is desired to discharge the coal from the bucket, whereby the bolts 11 b will be drawn, and the door will be forced open by the pressure of the coal inside, and the latter thereby discharged.

F represents the bail, which will be pivoted near the center of gravity of the bucket to the side walls, a a, as clearly shown in the drawings. This bail has a limited amount of play between the fixed stops f f. A pull on the rope G, one strand of which, itwill be understood, is permanently connected to the car on the elevated track and the other strand of which passes over a sheave on said car and thenceto the hoisting-drum, will cause the bucket to enter the pile of coal. A continued pull on the rope after the bucket isfilled will cause the bucket towithdraw from the pile of coal, and the bucket, assuming a vertical position, as shown in Fig. 2, will be drawn upward'to thecar, to which it will be connected bymeans of the block H, and will. then be drawnoif to'the dump. 7

It will thus be seen that the bucket ismade self-filling simply by the pull on the 1'ope,.and when it is unloaded and descends onto the coal-pile the rounded rear corner of the bucket insures its return to the level fioor without lodging on the coal-pile.

If special circumstances require the assistance of a man to manipulate the bucket, I prefer to employ stakes or levers, which will have a bearing on the rear end of the bucket, and this hearing consists of the stake-sockets I and rests I. The sockets are preferably cast and bolted to the sides of the'bucket, and are provided with the lugs 6 @between which the stake or lever will be thrust. By this means sufficient leverage is obtained to throw the bucket out of contact with the coal, and the stakes are readily removed, or even fall out, after the bucket is filled. When. it is de sired to force the bucket into the coal by use of the stakes or levers, the latter will be inserted horizontally between the castings I and and the rest I, and then an upward pull on the hand end of the lever will force the nose of the bucket to enter the pile.

It will be observed that the bail has a limited amount of play between the fixed stops f f, and this permits the bucket to assume a horizontal position, as shown in Fig. 1, while prevent it from tipping and cause it to mainbeing loaded, and after it is filled the stops tain a substantially perpendicular position while being elevated and transferred to the dock.

It is apparent that modifications of the minor features may be made and within wide limits without departing from the spirit of my inventionas, for example, in the method of securing and opening the door, and also, perhaps, in the shape or configuration of the bucket; but the form here shown I deem the best suited to the described purposes. I prefer to make the opening in the bucket of a diameter equal to the greatest width of the bucket, so that the filling shall be rapid, and the bail, pivoted, as shown, with its movement limited by the fixed stops, will effectually prevent the coal from spilling out between the pile and the dump. The upper stop, f, also materially assists in the filling of the bucket, because the bail engages said stop, which will be between thepower and the pivotal connection of the bail to the bucket, and thus act as a fulcrum to force the nose of the bucket into the pile of coal. The location of said upper stop in a bucket of the construction here shown will preferably be so that the bail will assume an angle with the floor of, say, fortyfive degrees; but a Variation from that angle, while not desirable, may be practical.

I claim 1. A loading and hoisting bucket having a front wall with a straightportion, a bail pivoted to opposite walls of the bucket at right angles to said front, and a bail-stop located on one of the walls to which the bail is pivoted and in such position as to be above the bail when the bucket is in the act of filling, whereby to limit the movement ofthe bail and to form a fulcrum therefor,substantially ment of the bail and to form afulcrum therefor in filling, and lugs on the walls .to which the bail is pivoted to provide bearings for levers, whereby to control the bucket in filling, substantially as described.

A loading and hoisting bucket having a front wall with a straight portion, a bail pivoted to opposite walls of the bucket at right angles to the straight portion, a bail-stop located on one of the walls to which the bail is pivoted, and in such position as to be above the bail when the bucket is filling, whereby to limit the movement of the bail and to form a fulcrum therefor, and a hinged door in the rear wall of the bucket and toward the bottom thereof, substantially as described.
