SPLIT BUCKET.

Application filed August 17, 1922. Serial No. 582,481.

A To all who/m, it may concern.'

Be it known that I, DANIEL STAIR, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Split Buckets, of which the following is a specification.

Thisinvention relates to a new and improved conveyor bucket, and more particularly to a two-part bucket adapted to be opened and closed by the action yof gravity.

In conveyor buckets it is highly desirable that the opening and closing means comprise 'but few' and simple elements, sincev the buckets undergo rough treatment and these elements are likely to become deranged or broken. It is further`highly desirable that the operation be accomplished without the addition of bucket opening and closing ropes or cables which unduly complicate the con- -veying system.

In order to provide a system of maximum eiliciency, the buckets must open and'close rapidly and must dump cleanly and quickly.

It is an object of the present invention to provide a bucket of the character described which is formed in twoparts adapted to be swung by gravity to the closed position when in the filling position and to be opened by gravity when unlatched while in discharging position. It is also an object to provide a gravit -operated latch for said bucket. It is a furt er object to provide a bucket which is simple in construction, composed of coinparatively few parts and which is relatively inexpensive to manufacture.

Other and furtherobjects will appear asv they description proceeds.

Broadly, m b'ucket comprises two parts l and hingedY together at the point above the center of gravity of the twoparts. Supporting'elements are provided located adJacent the hinge, .and the weight ofthe bucket is so p15 proportioned that when Supported by these elements, the two parts close. Means are rovided for automatically latching the ucket together when closed. A bail is provided' connected to the. two parts of the bucket preferably by flexible members so that the bail may swing outof'the way when.

loading. -The bail is attached at such points tothe Ptwo parts that when suspended from the bail the two parts to swing open l ivided upon a vertical plane' of my invention in the accompanyingdraw-- ings, in which- Figure 1 is a side view of the bucket in the closed position, the open position being indicated in dotted lines; l

. Figure 2 shows a, bucket as seen from above; l

(Figure 3 is an lend view of the bucket; an

Figure 4 is a view similar to Figure 1 but showing a modified form of latch.

The bucket comprises the two parts 5 hinged to ther at the point 6. The supporting ro 1ers 7 are fitted upon thel bucket substantially inline with the hinge pivot. These rollers are held in place by cotterpins 8. The upper adjacent faces of the-two bucket parts are cut away at 9 so as to permit the bucket to swing to the open position. The bottom 10 of .each bucket part is sloped downwardly toward the center in order that the bucket may quickly'discharge its entire y contents. The side walls of the bucket are also upon a slight inward slope. The catch 1 1 is located upon one half .of the bucket ber 15 provided at either end with a rigidA frame 16. The ends of these frames 16 are connected by -chains 17 to the straps 18, the latter being attached-to cross straps 19 which .v

are welded or otherwise securedto-the inte'- 4rior of the bucket corners. Thelch'ains 17 are adjustably connected by eyes 17 to the straps 18. The rigid member 15 i'nay be conf.

nected in any desired manner to a hanger or pulley or other element as desired.

The right hand bucket inember 5l is rovided with the lap stripA 24 which over aps the edge of the opposite member 5 when the b ucketi's'closed and thus forms a strong and tight Joint. The lap stri strengthens this part of the bucket andten s to prevent'bulg., ingl or other'deformationyunder load.

The guide angles 25 are secured to the' la strip 24 immediately Abelow the. ro1lers 7 andi.

ipo

" are so proportioned as to positively guide 'operation 1s accomplishedentirely by gravas clearly shown in Figure 3, these angles the rollers to the supporting rails."

The form shown in Figure 4: is similar in all respects to that of the other igures, with |the exception of the latch. 'llhe latch 12' of this form of the device is provided with the rearwardly extending arm 20 which is connected by the rod 21 to the operating lever 22, the latter being pivotedlto the upper portion of the bucket in the bracket 23.

In the use of my bucket it is normally connected to the conveyor by means of the bail member 15, and suspended in that Inanner, is moved about by the conveyor. When thus suspended the pull of the chains 17 tends to separate the two parts of the bucket. This tendency, however, is overcome by the latch 12 and catch 11.l When the form of bucket shown in Figures 1 to 3 is lowered so that the Jfoot 14: of the catch engages the ground, a pile ot discharged material, or any other substantially unyielding object, that end of the catch is moved upwardly and the catch is released. .The bucket then swings open and its contents are quickly and cleanly discharged by gravity. The bucket, remaining inthis open condition, is transported to the loading point or to some point Where supporting members such as rails are provided adapted to engage they rollers 7. The bucket is lowered until these rollers 7 leo engage the supports and carry the weight of the bucket, the angles 25 serving to guide the rollers to the rails.- Gravity then swings the two parts together and the latch 12 is cammed outwardly by the catch 11 and snaps into engagement with that catch.

llt is to be noted that not only the bucket itself but` the bucket latch are vity-oper-v ated,no springs or similar devices being required.

The form of latch shown in Figure 4i is operated by so moving the conveyor that the arm 22 is brou ht into engagement with any substantially wardly. rl"his movement of the lever serves to release the two of the bucket, which are discharged. llt will be observed that this form of latch may also be operated b bringing the arm 20 into engagement wit any substantially'unyielding Vobject by,7 lowering the bucket in contact with it in amanner similar to the other form of latch.

' lBy reason of the fact that the bail is com nected Ato the bucket by Atilerible members, the chains 17 permit the rigid bail members to swing substantially out ot the way of the incoming material 'when the bucket is loaded. The eyes 17 may beadjusted so that the bucket hangs event llt'is'tobe understood,

' of course, that the ucket is not a reclaiming Gti bucket, but is pted to be load trom"- above when the two parts are inthe'cld Xed object and is swung up-f y .innesco My improved bucket is extremely simple in design and rug t i in construction. lits .ity so that no additional bucket-operating ropes or similar elementsare required.

llt is to be understood that the forms of the bucket, the supporting elements and hinge being so related to each other and to the two bucket parts that when the weight of the bucket is carried by the supporting elements, *the two l by gravity,'and-a ail for said bucket connected to each part at such pointthat 'when parts are closed together v.

suspended from the bailI the hinged parts Y tend to swing open.
