'The inside radius of each gate is constant except that the center of the radius is offset toward the center of the bucket approximately one-third the distance from the hinge pin to the center of the bucket.

The operating means for the gates 9 comprises the U-shaped handle I or bail member, as it might be termed, the sides of this handle 1 at the ends being attached to offstanding arms l4 welded or otherwise secured at an upward angle to dependent hanger or link members l5 which are pivoted at IE to the skirt portions 4 of the bucket on the inner sides of said skirt portions. The handle 1 is riveted or otherwise fastened to the arms I 4 as shown at H, and universal or ball and socket joint means l8 are employed to connect the lower member of each handle or link member [5 with a cooperating link member I9. The lower ends of the two link members l9 are correspondingly connected by ball and socket or universal connections 20 to the gates 9, there being one of the members IQ for each gate, and the connection between each member l9 and the gate being located approximately at the center of the latter. It will be seen that the handle 1 is disposed at right angles to the swinging doors and that each side of the handle I has a connection with one of the doors only.

Obviously, according to the construction described, a downward movement of the handle 1 will rock the hangers or link members I5 laterally, and this will create an upward pull upon their associated links l9 directly attached to the doors. In this way the doors may be readily opened incident to said downward shifting of the handle, and the handle afiords a control for the doors permitting each opening to be as great as desired to thus control the amount of the stream of material which will pass from the bucket to the point where it is to be deposited.

A spring latch member 2| near the upper end of the bucket may be utilized to interengage with the cross portion of the handle 7 in order to hold the handle upraised and thus substantially lock the discharge gates or doors 9 in closed positions.

At the upper end of the bucket is a supporting crossbar 22 with which block and tackle may be connected for hoisting the bucket, or any other support attached by which the bucket is to be transported from one place to another.

I may make the link member l9 of end members I9a into which the body portion ofthe link members [9 may screw at the ends. I may also form at the central portion of the body of each link IS a poly-sided member 23 for application of a wrench, and, by turning the central body portion of the link l9 relatively to the parts l9a, adjustment of the links may be obtained so as to make easy the maintenance of the doors or gates 9 in closed positions'even after a considerable amount of wear may have been caused thereon.

According to the construction of the invention in Figure 10,1 utilize a double handle 24 comprising an upper U-shaped portion attached to arms M such as before described, and a lower U-shaped portion attached to other arms Ma in alignment with the arms H but extended opposite from the angle members l5 as regards the direction of extension of the arms l4. The lower handle members 24 are thus in alignment but disposed at opposite sides of the bucket. In this way the bucket discharge doors or gates may be readily operated by a person standing on either of opposite sides of the receptacle. Inone instance the upwardly and normally disposed handle 24 will be pushed downwardly and in the other instance the lower normally disposed handle 24 will be pulled upwardly. If desired, a catch or latch device may be utilized to lock the handle members 24 in their positions in which they maintain the bucket doors or gates closed.

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

1. In a bucket of the class described, in combination, a body having a discharge opening at its lower portion, a gate movably mounted on the body and normally having closing action in relation to said opening, a handle pivoted to the body and disposed with its axis at a right angle to the axis of the gate, and linkage connection between said handle and the gate whereby on movement of the handle the gate may be carried to open and closed positions at will, said linkage connection comprising a hanger member pivotally connected to the body and a link connecting said hanger member with the discharge door, the connection between said linkage connection and the handle comprising a rigid member attaching the handle to said hanger member.

2. In a concrete bucket, in combination, a body having a discharge opening at its lower end, oppositely swinging discharge gates normally closing said opening and mounted on said body, an actuating connection between each gate and the body consisting of a hanger member pivoted to the body, and a link connecting the hanger member to the gate, and handle means pivoted to the body with its axis at a right angle to the axes of the gates and connected to said actuating connection for shifting the same to cause opening and closing movements of the'gates.

3. In a concrete bucket, in combination, a body having a discharge opening at its lower end, oppositely swinging discharge gates normally closing said opening and mounted on said body, an actuating connection between each gate and the body whereby said gates may be moved to open or closed position upon actuation thereof, consisting of a hanger member pivoted to the body, and a link connecting the hanger member to the gate, and a handle member comprising a U- shaped body the sides of which are rigidly attached to the hanger members of said actuating connections, whereby on movement of the handle member opening and closing movements of the gates may be produced.

4. In a concrete bucket, in combination, a body having a discharge opening at its lower end, oppositely swinging discharge gates normally closing said opening and mounted on said body, an actuating connection between each gate and the body consisting of a hanger member pivoted to the body, and a link connecting the hanger member to the gate, and a handle member comprising a U-shaped body the sides of which are rigidly attached to the hanger members of said actuating connections, whereby on movement of the handle member opening and closing movements of the gates may be produced, said handle member being disposed to swing at right angles to the direction of swinging movement of the gates, and the links of the actuating connections being attached to the central portions of the gates, the said actuating connections being further disposed in a plane centrally bisecting the body.

5. A bucket substantially as claimed in claim 2, wherein the hangerlmember of each actuating connection has a universal joint connection with its link and wherein each link of the actuating connection has a. universal connection with its associated gate.

6. In a bucket such as described, a body having a discharge opening at its bottom, a gate adapted to assume a position in closing relation tothe opening, supporting means permitting movement of the gate to open and closed positions, actuating means for opening and closing the gate, said actuating means comprising a connection between the gate and the body and handle means extending from said actuating connection to option from such oppositesides, said actuating connection comprising a hanger pivoted to the body and a link connecting the hanger to the gate, an upwardly inclined handle rigid with the hanger member and extending to one side of the bucket, and a second handle member extending from said hanger member to the opposite side of the bucket from that at' which the first handle member is disposed.

'7. In a bucket of the class described, in combination, a body having a discharge opening, oppositely swinging gates pivoted at theirends to said body and normally having closing relation to said opening, a U-shaped handle pivoted to the body at opposite sides thereof, and linkage connection between each end of the handle and the adjacent gate attached to said gate intermediate the pivoted ends of the latter.

8. A bucket of the class described, comprising, in combination, a body having a discharge opening at its lower end, a gate pivoted to said body and adapted to assume a position in closing relation to the opening, a swinging handle pivoted to the body and disposed with its axis at a right angle to the pivotal axis of the gate, and linkage connection between said handle and the gate whereby on movement of the handle the gate may be carried to open and closed positions at will.
