side elevation, with parts broken away,

showing an embodiment of the invention as adapted for use in connection with a swinging boom crane; 'Fig. 2v is a longitudinal medial section, on an enlarged scale showing the devices. of the invention as adapted to the drag line bucket operation; and Fig. 3

is a plan view. of the bucket, with partsbroken away.

The rotatable platform .1

to the bucket 7 The hoisting line 5 engages the suspension arm 8 pivotally mounted on the bucket 7 within the width of the bucket.

The suspension arm 8 has mounted therein roller carrying pin 9 movable into the notch 4 in slot. 14 of the reciprocable tripping ele-- ment or trigger 15 of the holding device.

This element 15 is guided by the sleeve l6 in its reciprocations to force the pin 9 out of the notch 10, and may not move to a vertical position owing to pin 12 over which it rides and as to which it is held by sleeve 16.

The sleeve 16 is pivotally mounted by the pin 13 ,in the forks of the holding device or book 11 carried by the pin 12.

Pivotally connected to the forward end of the bucket 7 is the draw member 17 hav-' ing the'way 18 in which isreciproca-ble the block 19, about which block 19 the drag line 6 extends before being connected to thedraw member 17. Connected to the block 19 is the pair of flexible connections 20 extending through guides 21 on the bucket 7 to the eyes 22 on the armsections 8, to limit the oscillation of the bucket. Tovlimit the has mounted thereon the prime mover 2 and the boom 3. The angle of the boom 3 may be adjusted by the line 4, while the hoisting or suspension 1 line 5 and the drag or haul line 6 extendpension arm sections 8. This line 24 also limits the swingof the bucket relatively to the draw member and suspending arm. The bucket 7 is shown in this instance as provided with a pivoted back, to aid in the dumping operation. To supplement the free ng of material tending to adhere to the bucket back, the showing embodies the back frame 26 having an openwork back therein comprising chain links 27, which in the bandling of the bucket will vibrate and thus shake material free therefrom. As an extension from this screen back, is shown the hinged member 28, which has a scooping action in the dumping operation. The pivoted back is shown as directly connected to the suspension arms 8 to be movable therewith. The bucket bottom is provided with longitudinally extending guiding and scoring vanes 29, efiective not only to keep the bucket lined up for proper travel in the digging operations, but also serving to loosen up the material, thereby aiding subsequent filling "'of the bucket. Topermit adjustment of the forward limit of travel of the block 19, openings 30 are provided in the member 17, in which openings pin 31 may be inserted.

In operation, the platform 1 is swung so that the boom 3 hangs over or toward the material to be moved, and the hoist line 5 is so paid out that the bucket 7 may properly land in position thereon as guided by the drag line 6. The scoring vanes 29 engaging in the loose material, tend to keep the bucket 7 from working out of line of the haul cable 6 during the filling of the bucket. With tension upon the haul line 6, block 19 is drawn to its forward limit of travel along the way 18, which causes the drag member 17 to be inclined downwardly due to the connections 20. This deflection of the member 17 .is adjustable'by'the pin 31 varying the forward limit of travel of the block 19. By this adjustment the angle of travel of the bucket into the material may be regulated,

the draw member having a sort of plow beam action. In this travel the back of the lines in Fig. 2. When the bucket 7 is filled,

it is lifted by the hoisting line 5, draw line 6 being paid out sufliciently to control the position of the bucket, while the platform 1 is 5 swung to bring the boom 3 into position over the dumping place-for the material. With the bucket 7 hus suspended for dumping, the draw line 6 is slacked, which permits the heavy outer end of the draw member 17 to swing downward, as shown in dotted lines in Fig. 2, which travel of this member 17 in the path of element brings about a contact by member17 with the lower end of this element 15, which concussion ushes 15elcment 1.5 from the full line ositlon, to the dotted line position shown in ig. 2, thus effecting movement of this element 15 into the notch 10 to force pin 9 out of this notch, thereby tripping the bucket 7, permitting 20 the released forward end of the bucket to swing downward as shown 'in full lines in Fig. 2. In this swinging operation, the line 24 pulls the draw member up so that it may not interfere with the free fall of material 25 being discharged from the bucket. The slacking of line '6 permits the block 19 to travel toward the inner end of the way 18 as guide 21 pulls the connections 20 to the limit of the bucket oscillation. Simultaneously with this inclining of the bucket, the back-26, due to its connection with arm 8, swings forward relatively to the bucket,

with its extension 28 scooping the material I out of the bucket 7. The more or less viof this dumping operation shakes the cham links 27 to free any ma-; terial tendin to stick thereto. Tendency toi lence attendin clog the buc et is therefore avoided, while the advantages of draining are assured. As

40 member 17 was swung upward in the dumping operation, the element 15 moved back to leave the notch 10 clear. After dumping, the slack in line 6 is taken up, drawing may be 'had as the bucket is being for landing or dumping.

What is claimed and it is desired to secure I by Letters Patent is:

1. A bucket, a trip connected to the bucket, a hoisting member for the bucket and detachably connected to the trip to hold the bucket in material retaining position, a

drag line, a connectin beam between the drag line and the buc et, and connecting means to the trip engaging the beam be- .tween the bucket and drag line and efl'ective by slacking of the drag-line to detach 0 the trip from holding the bucket in material retaining posit-ion.

. 2. A bucket, a suspending arm therefor, a return line' for the bucket connected to the suspending arm, a, trip mounted on the 5 bucket and havi a trigger, said trip detachably connecte to the arm to hold the arm from movement relatively to the bucket, and in addition to the suspendin arm a drag line to the bucket and provi ed with 0 means movable upon slacking of the drag line to move the trigger to disconnect the arm from the trip to permit free swinging of the return'line held arm as to the bucket at different positions of the bucket. 5

3. A bucket, a disconnecting trip for the bucket, a hoisting member engaged by the trip, a draw member mounted on the bucket and movable relatively to the bucket to actuate the'trip, and a drag line connected to the member and effective by slacking to cause the draw member to actuate the trip t disconnect the hoisting member for free swinging relatively to the bucket.

4.
