Abstract
A bucket support for swingably and removably supporting a backhoe bucket on a dipper stick which includes a releasable mechanism for releasing and attaching the bucket from the bucket support. The releasable mechanism is made up of a first forwardly facing hook for receiving the front support pin of the bucket and a downwardly facing notch which receives the rear pin on the bucket, and a second hook attached to the bucket support that swings under the rear pin of the bucket when it is supported in the downwardly facing slot notch.
Claims11
A bucket support for supporting a bucket on a backhoe dipper stick, said bucket support comprising two spaced, side plates,
- pivot means for pivotally connecting said side plates to said dipper stick to pivot about a first axis,
- spaced brackets fixed to said spaced plates and extending downward therefrom,
- a first carrier and a second carrier spaced from one another and supported on said side plates, said first carrier having a forwardly opening slot in its lower end adapted to receive a pin of a backhoe bucket, said second carrier having two spaced support plates fixed to its sides and extending downwardly therefrom,
- a downwardly opening slot in each said spaced support plates,
- at least one hook disposed between said spaced support plates and pivot means swingably connecting said hook to said spaced support plates, said hook having a forwardly opening slot, said hook being adapted to swing under a pin supported in said vertically extending slots,
- a laterally extending bar attached to said hook and extending laterally thereof and a handle attached to said bar,
- two spaced helical tension springs attached at their upper end to said bar,
- the lower end of said springs being attached to means on said support plates,
- said springs urging said second hook to swing to closed position.

- said king pin supported on king pin support means,
- means to swing said king pin about its longitudinal axis,
- a first carrier and a second carrier supported on said king pin and extending downwardly therefrom,
- hydraulic cylinder means on said bucket support to swing said carriers about the axis of said king pin,
- said first carrier having a first hook on its lower end adapted to receive a first pin on a backhoe bucket,
- said second carrier having spaced downwardly extending plates fixed thereto,
- an upwardly extending slot in each of said spaced plates adapted to receive a second backhoe bucket pin,
- a second hook disposed between said plates,
- a laterally extending bar attached to said hook,
- pivot means supporting said second hook on said plates,
- first lug means attached to said spaced plates,
- second lug means attached to said laterally extending bar,
- at least one helical tension spring having a first end and a second end,
- first means connecting said first end of said tension spring to said first lug means,
- second connecting means connecting said second end of said tension spring to said second hook,
- urging said second hook means to swing toward said first hook and under said second backhoe bucket pin,
- closing the lower ends of said upwardly extending slots and retaining a said second backhoe bucket pin.

A tool support for attaching a tool to a boom comprising pivot means for attaching said support to said boom to swing about a first axis,
- attaching means for attaching said tool support to said tool,
- a king pin and means on said pivot means to swing said king pin about a second axis perpendicular to said first axis,
- a first carrier member,
- said first member being attached to said king pin and having first downward extending carrier member terminating at its lower end in a forwardly facing first hook,
- a second carrier member spaced from said first carrier member and attached to said king pin,
- said second carrier having two spaced downwardly extending plate like members attached to said second carrier member and spaced from said first hook member,
- a vertically extending slot (245) in each said plate like member,
- said slots being open at their lower ends,
- said slots being each defined by two spaced generally vertically extending sides comprising a first side and a second side,
- said second sides being inclined upwardly and towards said first side and terminating at its top in a generally cylindrical seat for a pin on a tool,
- a second hook having a pivot pivotally supporting said second hook on said second carrier to swing about said second hook pivot,
- a helical tension spring,
- said spring being connected to said second hook adjacent its upper end and to said spaced plates adjacent its lower end urging said second hook to swing towards said second side of said slot,
- said hook having a curved side adapted to define with said second side of said slot a generally "V" shaped recess adapted to receive a pin on said tool,
- whereby when said tool support is lowered onto a pin bringing said pin into said "V" shaped recess,
- said hook is urged rearwardly, allowing said pin to pass said hook and to be received on said cylindrical seat so that said hook can swing under said pin.
