HOISTING-BUCKET MECHANISM.

Specification of Letters Patent. Patented Mar. 12, 1918.

Application filed June 21, 1917. serial No. 176,086.

To all whom it may concern:

Be it known that LJAMES S. MILLER a citizen of the United States, residing at Unity Station, Allegheny county, Pennsylvania, have invented a new and useful Hoisting-Bucket Mechanism, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a sectional elevation of hoisting mechanism, embodying my invention with a hoisting bucket 1n an intermediate position.

F 2 is a similar view with the bucket.

and adjacent parts in dumping positions.

Fig. 3 is a front elevation of the bucket frame and bucket. I

Fig. l is a section on the line IVIV of Fig. 3.

Fig. 5 is a perspective view of the door operating lever of Fig. 4, and

Fig. 6 is a view similar to Fig. 1, but showing a modification.

My invention has relation to hoisting buckets, and to means for discharging said buckets; and is designed to provide mechanism of this character which can be operated without destructive action upon the tower or guides in which the bucket runs; which will permit the bucket to be discharged without splashing; and, in which the discharge is of such character as to thoroughly flush the bucket at each discharge, and thus prevent clogging thereof.

he particular nature of my invention will be best understood by reference to the accompanying drawings in which I have shown preferred forms thereof, and which will now be described, it being premised, however, that various changes can be made in the details of construction, arrangement, and combination of the various parts without departing from the spirit and scope of my invention, as defined in the appended claims.

Referring first to that form of my invention shown in Figs. 1 to 5, inclusive the numeral 2 designates the frame work of the tower or guides upon which the bucket is raised and lowered.

These guides may be, in general, of any usual or suitable character.

The hoisting bucket has a straight front wall 3, a forwardly and downwardly inclined bottom and rear wall 4, and end walls 5, there being a door opening 6 be tween the lower edge on the front wall 3 and thelower portion of the wall 4. This opening is controlled by a vertically sliding door 7 which is pivotally mounted on one arm of a lever 8. This lever is pivoted at 9 to a suitable support or bracket, which is fastened to the frame or carrier 11 of the bucket, the lever 8 having a rearwardly projecting arm 12 beyond the pivot 9.

3 designates a guide rod or link which is also pivotally connected to the door 7 and which extends rearwardly through a guide 14 in a bracket 10, in which guide it is loosely seated, being held by the adjustable nuts 15. 16 designates a guiding or discharging trough secured to the bucket. 17 is a receiving hopper mounted on the frame 2 and into which the bucket 3 is arranged to discharge.

Pivoted to the upper rear corner portion of the hopper 17 is a trough-like guide 18, having connected to its upward forward corner portion a rod 19, which extends upwardly and normally rests against one of the guides 2 of the frame 2 in the path of movement of the upwardly traveling bucket.

20 is a tripping lug or projection of frame 2.

The operation is as follows: Shortly before the ascending bucket reaches the position shown in Fig. 2, the arm 12 of the lever 8 comes in contact with the tripping projection 20, thereby moving said lever 8 to raise the door to the open position, indicated in Fig. 2. During the opening movement of the door, it is guided by the rod or link 13, which, swinging from a different center than that of the pivot 9, acts to prevent an binding of the door against the wall of the bucket. At the same time, by means of the nuts 15, the door may be kept sufiiciently tight, when closed, to prevent leakage of any liquid contents. It will be understood that the various pivotal connections of the lever 9 and door 7 are made sutiiciently loose to permit free action.

At about the same time that the door commences to open, the bucket 3 Comes in contact with a projection 19 on the rod 19, thereby moving said rod to raise the guide 18 to the position, shown in Fig. 2; that is to say, in the position to receive the discharge from the spout 16 and to direct it into the hopper 17.

The contents of the bucket readily discharge by gravity, owing to the internal shape of the bucket, and flow out into the hopper 17 with very little splashing This discharge is also free from any destructive jars, such as occurs whendunipingan invertible bucket. In handling mixed solid and suchas stock used in con-v charged, leaving the more solid portions in the bottom of the bucket.

Theform of my invention first described is illustrated in connection with a sheet metal bucket. In Fig. 6 I have shown a-modificatioii more especially designed for, use in connectionwith a wooden bucket. The construction and moving operation is, in all sub stantial respects the same as that first described and corresponding parts have been given preceding figures with the. letter b affixed thereto.

The advantages of my invention will be apparent to those skilledin the art, since it provides a self discharging-hoisting bucket and efiicient character, requiring of simple little attention-on the part ofthe operator, in the use of which objectional splashing and-jars are eliminated;
