TWO-LINE AUTOMATIC DUMPING-BUCKET.

Specification of Letters Patent.

Application filed July 12, 1913. Serial No. 778,640.

To all whom it may concern:

Be it known that I, GUsTAvUs L. STUEB- NER, a citizen of the United States, and. a

latter in position, when the doors are in their closed position. The movable bail, and latch and suspension link are each controlled by chains or ropes.

In the accompanying drawings Figure 1 represents a side elevation of a bucket with the invention incorporated therewith, Flg. 2 shows a top plan view of Fig. 1, Fig. 3 represents a fragmentary section of Fig. 2 on the line 3, 3, Fig. 4 shows an end View of a detail, Fig. 5 is a top view of Fig. 4, Fig. 6 is a right hand side view of Fig. 1, Fig. 7 shows a side elevation of the bucket with the movable elements in a changed position and Fig. Sis a side viewof F 7 The body of the bucket is represented in its entirety by the numeral 20 with the side walls 21, 22, the front wall 23 and the rear wall 24. to the top edge of the body. of the bucket. A reinforcing band 26 is riveted to the lower portion of the body of the bucket. A portion of the lower edges of the side walls 21, 22 and the accompanying portions'of the band 26 are cut away as represented at 27 to obtain a little clearance between the side walls 21, 22 and the swinging bottoms to be described, when the latter are in their closed positions; To the outer surfaces of the sides 21, 22 are fastened the pairs of angle iron guide rails 30, which at their upper ends have connected thereto the connecting brace 32. Braces 35 connect each pair of guide rails 30, with the reinforcing band 25, and guide bars 36, 37 are fastened to the sides 21, 22. Abutting strips 38 are fastened to the reinforcing band 26 over the side walls 21 and 22. To the band 26 over the front and rear walls 23, 24 are riveted the angle irons 41. To the latter are riv- A reinforcing band 25- is riveted V Patented Apr. 4, 1916.

eted the hingebrackets 42 having formed I therewith the journal supports 43. Rectan-j gular hinge bars 44 have formed therewith the cylindrical journal ends 45 that are sup-- ported'in the journal supports 43. To each of the rectangular hinge bars 44 is riveted a U shaped swinging door having the bottom plate 50 and the side walls 51. To each bottom plate are riveted reinforcing angle irons 52, 53. Brackets54 with the pivots 55 are rivetedto the side walls 51 of the swinging doors.

A stationary bail 58 with the suspension 'pin 59 is fastened to the body of the bucket by means of the angle braces 60. A movable bail '61 with the suspension lug 62 having the opening 63 is guided between the pairs of angle guide rails 30, and a latch pin 64 extends from the bail 61. At the ends of the movable bail 61 are formed journal pins 65 and'adjacent to its central portion is riveted a guide bracket 66. 'Pairs of links 70,

71 connect the pivots'55 with the journal pins 65. The ends of the pins 65 are threaded for the nuts 72. A U shaped combined latch and suspension link designated in its entirety by the numeral 73, and having one leg which I designate the latch arm 74, and V a second leg which I designate the link arm 7 5, is pivoted on'the suspension pin 39. The link arm 75 extends through the opening between the bail 61 and bracket 66 and has formed at its upper end the eye 76. The

latch arm 74 has the upper curved end 77, which supports and locks the pin 64 in position, when the bail 61 is in its highest position. The arm 75 is heavier than the arm 74, so as to overbalance the latchand suspension link toward the arm 75. r A hook 80 with the chain 81 is shown connected with the lug 62, anda hook 82 with the chain 83 is represented connected with the eye 76.. M

. To use the bucket it may in the first instance be considered with its bottom swinging doors having thebottom plates 50 closed as indicated in Figs. 1, 2, 3 and 6. The bucket is shown suspended by means of the hook 80 and chain 81. The chain 83 has been slackened which has tipped the latch and suspension link 73 to the position shown, particularly in Fig. 6, the curved end 77 of the latch arm 74 supporting and locking the latch pin 64 in position and maintaining the bottom swinging doors having the bottom plates 50 in their locked position. While the doors are in'this position, the top edges of the side walls 51 thereof bear up against the abutting strips, 38. Should it be desired to dump the charge in the bucket, the chain 83 is pulled taut and thereby the combined latch and suspension link 7 3 is tipped to its upright position, shown particularly in Fig. 8, and whereby the curved end 77 of the arm 74 becomes disengaged from the latch .pin .64. The operator now pays out the chain 81, and thereby 10w ers thev bail Gland the swinging bottom doors drop to their open or lowered positions. To close the doors of the bucket the operator pulls on the chain 81 and slackens the chain 83, which raises the bail 61, closes the swinging doors and tips the combined latch and suspension link 73 to its inclined position shown particularly in Fig. 6, the arm 74 being then disengaged from the latch pin 64. It is to be notedthat the coaction of the chains 81 and SEE-with the U shaped combined latch and suspension link 73', and the latch pin 64 of the bail 61 and its support in the guide bracket 66 produce an automatic locking device for the bucket. The invention might be modified by suspending the combined latch and suspension link 73 to the movable bail 61 instead of the bail 58 and the construction not depart from the invention, and in such a case the latch and suspension link 73 would lock with the bail 58, that is to say with a pin thereon.

Having described my invention what I desire to secure by Letters Patent and claim is: T

1. The combination with the body of a bucket of a movable bail, a pair of doors hinged to the body of the bucket, a stationary bail secured to the body of the bucket, a'

combined latch and suspension link pivoted to the stationary bail and the latch of the combined latch and suspension link locking the movable bail by gravity when the doors are in their closed position.

2. The combination with the body of a bucket of a movable bail having a latch pin extending therefrom, a pair of swinging doors hinged to the body of the bucket, connections between the doors and said movable bail, a stationary bail secured to the body of the bucket, a combined latch and suspension link pivoted to the stationary bail having a latch arm and suspension link, the latch arm looking with the latch pin when the doors are in their closed position and a chain connected with the suspension link.

3. The combination with the body of a bail when said latch'and suspension link is,

in an inclined position and thereby looking the'doors in their closed position, a

chain for the movable bail and a chain for the suspension link of the combined latch and suspension link. 4. The combination with the body ofa bucket of a movable bail, having a latch pin extending therefrom, a chain connected to the movable bail, a pair of guide rails on 7 two opposite sides of thebody of the bucket for said movable bail,a pair of swinging doors hinged to the body of the bucket, piy

ots on the sides of .the doors, a pair of links on each side of the body of the bucket with one end of each link supported on the movable bail and the other ends of the links supported on the pivots of the doors, a stationary bail fastened to the body of the bucket, a suspension pin extending fromthe stationary bail, a combined latch and suspension link pivoted on said suspension pin.

and ha inga pair of legs, one of said legs locking with the latch pin of the movable bail when the doors are in their closed position, and a chain connected to the otherleg.

Signed at the borough of New York in the county of New York and State of New York this 9th day ot-July, A. D. 1913.
