BOTTOM-DUIVIPING BUCKET.

To all whom 'it 'may concern:

Be it known that I, GUsravUs L. STUEB- NER, a citizen of the United States, and a resident of Flushing, in the county of Queens and State of New York, have in vented certain new and useful Improvements in Bottom-Dumping Buckets, of which the following is a specification.

This invention relates to bottom dumping buckets. Its organization comprises a bucket with a movable bail, connected by links to the doors thereof and means for locking the bail to the bucket when the doors are swung to their closed position, and other means to maintain the bail with its appurtenances at various angles, to vary the inclinations of the doors when lowered from the body of the bucket. A stationary bail is also provided for the bucket, the vertical cross axial plane of which passes preferably through the center of gravity of the bucket, and the similar plane of the movable bail is distant from the said plane of the stationary bail, so that the chains for the bails will not interfere with each other.

The buckets are particularly useful for handling concrete, but may be used for any other material.

In the accompanying drawings Figure l represents an elevation of a bucket exemplifying the invention, Fig. 2 is a top plan view of Fig. l, Fig. 3 is a view similar to Fig. 1 with doors in a lowered position, Fig. 4 shows, a right hand side view of Fig. l, and Fig. 5 is a bottom plan view of Fig. 4.

The bucket exemplifying the invention is shown with the body having the sides 21, ends 22, upper reinforcing band 23 with the supporting angle 24, lower reinforcing band 25 and lower crossbraces 26, the ends of which latter are connected to the angle irons 27 extending from the inner faces of said ends 22. Angle irons 28 extend from the sides 2l and support the stationary bail 29. A hook 30 with the chain 31 is shown suspending the vertical stationary bail 29. Hinge straps are fastened to the ends 22 of the bucket and are straddled by the journal lugs 36 extending from the doors 37 and 38. The lugs 36 with their doors are hinged to said hinge straps 35 by means of the hinge pins 39.

Each of the doors '37 and 38 comprise a cover 42, which is supported on an inverted box shaped frame 43, and a lip 44 extends from the lower face of one of the covers 42 Specification of Letters Patent.

and bears up against the lower face of the cover of the accompanying door when they are in a closed position. Plates 45 with the pins 46 and plates 47 with pins 48 extend from the box shaped frames 43 of the said doors, the plates 47 with their pins 48 being somewhat more distant from the inner end of their door 38, than 'the distance of the plates 45 with the pins 46 from the inner end of the door 37.

Angle irons 50 and 5l extend from the sides 2l of the body of the bucket and constitute guides for the operating and movable bail to be described. Openings 52 are formed in said angles for stop pins 58 which are suspended on chains 54 having their upper ends fastened to the sides 21 of the bucket. Guide pockets 55 are fastened to the sides 2l of the bucket for the pins 53 when the latter are not in operative position.

Angle irons 60, 61 and 62 are fastened to the sides 2l of the bucket, the angle irons and 6l, being located between angle irons 50 and 51. The angle irons 60 constitute stops for the said operating and movable bail, and the angle irons 6l and 62 constitute guards to prevent the bending of the links to be described should they be struck when using the bucket.

Links 65 have their lower ends fulcrumed on the pins 46 of the door 37, and links 66 somewhat longer than the links 65 have their lower ends fulcrumed on the pins 48 of the door 38. The upper ends of each pair of said links 65 and 66 arefulcrumed on the pins 67 extending from the hook ends 68 of the operating and movable bail 69. The movements of the pins 67 are main tained in vertical planes, by virtue of the hook ends 68 of operating bail being guided between the guides 5() and 5l. The locations of the pins 46 and 48 with the lengths of the links 65 and 66 maintain the doors 37 and 38 at approximately equal angle with the bottom edge of the bucket when the said doors are lowered therefrom. When the doors are in their closed position links 65 are in vertical positions and the links 66 are inclined thereto. The lower inner openings 70 of the hook ends 68 are formed with the walls that are arcs of circles described from the centers of the pins 67, andthe said hook ends are engaged with locking pins 71 extending from the bucket, when the doors are locked in a closed position with respect to the opening through the body of the bucket. The said pins 7l With said hook ends (3S constitute a locking device. The hook ends GS extend from the sides of the bail and the latter are formed With the main portion 72 thereof.

A ring hook support 73 is fastened to the main portion 72 of the operating bail, and bears on the supporting' angle Q4, When the doors 8T and 3S are in a closed position and the hook ends G8 are engaged by the locking pins 7l. Hooks 74C with the chain 75 are connected With the operating and movable bail 69.

To explain the operation of the invention the bucket can be considered with the doors 3T and 8S loWeredfrom the body thereof, as shown in Fig. 3, and the bucket suspended with the chain 3l supporting the stationary bail 29 and the chain 75 supporting the operating' and movable bail G9, the hook ends 68 bearing on the angle irons 60. The bucket is non' lowered to receive its charge and at the same time the chain 75 is hauled in Which Will close the doors 37 and 3S against the body of the bucket, and the said hook ends G8 will become engaged with the locking pins 7l firmly holding the doors in place. The chain 75 may non'v be paid out While the bucket With its doors closed is bearing on a support, when the operating bail Will fall to the left side of the locking pin 67 and bear on the supporting angle 2t, by reason of the left side of the said operating bail being' heavier than the right side. lWhen the bail is thus supported on the angle 2l it is securely locked with the locking pins 7l. Then the bucket is to discharge its charge the chain 75 is hauled in Which Will cause the bail (39 to assume its vertical position and allenY the hook ends to disengage from the locking pins 7l, by virtue of Which said hook ends will drop to and bear on the angle irons 60 and the doors Will drop to the positions shown in said Fig. 3.

The angles of the doors 37 and 38 With the bottom of the bucket When in their lowered positions, can be varied by inserting the pins 53 in the diiferent openings 52.

The invention may be modified by using only one door with the body thereof and one link like 65 or 5G at each of the sides thereof.

Having described my invention what I claim as new therein and desire to secure by Letters Patent of the United States is:
