Fig. 5 is a detail view, means maybe employed to afford connection u o between the auxiliary or supplemental bail 10 and the bucket 1, if found desirable in practice.

A supplemental or auxiliary bail 10 may be employed formed of one piece of bar metal or other suitable material and is preferably provided with an intermediate eye or loop 11, formed therein or connected therewith and with eyes or rings 12 at the extremities thereof constructed to engage the hook 7 upon the diametrically opposite sides of the bucket 1 and to move upon said hooks during the operation of the device.

Referring to Figs. 1, 4, 5, and 6, there is illustrated an engaging device embodying a hook 13, preferably provided with an integral eye or ring 14, substantially as illustrated in Figs. 5 and 6, and the hook is desirably constructed with an extension or lug 15, Fig. 6, and the construction of the hook 13 is preferably such that when the conveyer or bucket is hung thereon by its bail loop 5 the center of gravity of said hook will be out of a straight line connecting the eye of said hook and the bearing-point of the loop 5 on the hook, whereby when the con veyer or bucket rests on its bottom and the supporting means 16 is slacked the hook will swing upon the point of connection of its eye with said means and automatically be disengaged from the loop 5. This operation may be aided by the connection of the bail 10 with said hook as to be slightly off the center of. gravity, so that when the hook is released from engagement with the loop 5 of the bail 4 by slacking or the descent of a rope or cable 16 the hook will turn or rotate about the point of connection of the eye thereof with the supporting means or rotate into a reverse position, as shown in Fig. 4 of the drawings.

By means of the aforesaid rotation or reversing of the hook 13 when released from engagement with the bail accidental engagement of the former with the latter is rendered impossible when the rope or cable 16 is elevated to effect the dumping of the contents of the bucket through the mediation of the auxiliary bail 10, as shown in Figs. 2 and 4 of the drawings.

A clip 17, Figs. 5 and 6 of the drawings, is preferably constructed with a bifurcated end 18, in which is pivoted the extension or lug 15 of the hook 13, and a headed rod 19 is preferablyswiveled in the clip 17, substantially as shown in Fig. 6, and the end of the rod may be coiled upon itself, essentially as shown at 20, Figs. 4 and 5, after passing through an eye or ring 21 in a spring clip or snap 22.

A spring clip or snap 22 may be employed having a hook portion .23, with which is operated a spring-actuated pivoted jaw 24 to efiect detachable connection with the eye or loop 11 of the supplemental hail, the clip 22 being shown in engagement with said loop in Figs. 1 and 4 and detached therefrom in Figs. 5 and 6 of the drawings.

The operation of the invention will be readily understood from the foregoing description when taken in connectionwith the accompanying drawings and the following explanation thereof. The hook 13 is caused to engage the loop 5 in the bail 4, the snap 22 having been previously connected with the eye 11 in the supplemental bail, and the bucket is then filled with the material to be conveyed or transported, it being understood that the rope or cable 16 is always kept taut after the hook has been brought into engagement with the bail, and when it is desired to discharge the contents of the bucket it is only necessary to lower or slack up on the rope or cable 16, which effects disengagement between the hook and bail, the conveyer or bucket at the time resting upon its bottom, so that when the rope or cable 16 is raised or tightened up there will be no possibility of the hook rengaging with the bail, by reason of the hook then being directed away from the latter. By the continued elevation or tightening up of the rope or cable the supplemental bail, being pivotally connected with the bucket near the bottom thereof, will effect the overturning of the same, thereby discharging the contents of the bucket, the parts then being in the position substantially as illustrated in Fig. 4 of the drawings.

It is not desired to confine this invention to the specific construction, combination, and arrangement of parts herein shown and described, and the right is reserved to make all such changes in and modifications of the same as may come within the spirit and scope of the invention and that may be found necessary in practice.

tVhat I claim is 1. A conveyer provided with a main bail and havinga supplemental bail pivotallyconnected therewith, a hoisting-line and a device attached thereto and connected with the'latter bail constructed to support the conveyer in carrying position when in engagement with the former bail and when disengaged therefrom to rotate about the point of connection thereof with said lineout of reengagement therewith to eifect the discharge of the conveyer upon the tightening of said line.

2. A conveyor provided with a main and a supplemental bail, a hook connected with the latter constructed to detachably engage the former when forced away from the conveyer and to rotate about the point of suspension thereof out of accidental reengagement with the main bail when such force is released.

3. A conveyer provided with a main and supplemental bail, a supporting-line and a hook attached thereto and detachably connected with said supplemental bail constructed to retain engagement with said main bail while said line is taut and to rotate about the point of connection thereof with said line out of such engagement when said line is relaxed to prevent accidental reengagement.

4. A conveyer provided with a main and a supplemental bail, a supporting-line and a hook attached thereto and having swivel connections with said supplemental bail constructed to engage said main hail when said line is taut and to rotate upon said swivel and the point of connection thereof with said line out of engagement when said line is relaxed.

5. A eonveyer having a main bail rigidly secured thereto and having a supplemental hail movably connected therewith near the bottom thereof, a supportingline, a snap connected with said supplemental bail and a hook swiveled to said snap at one side and connected at the straight end with said line, whereby the hook retains engagement with said main bail while the lineis taut and rotates on said swivel and the point of connection
