Bucket Fabrication

Abstract

A back hoe bucket assembly of a kind having a bucket defining cavity bounded by spaced end plates, a cutting edge plate, one or more other plates spanning between the end plates, and a hitch assembly on the bucket for attachment to a complementary boom attachment. An angle plate extends above the bucket to span to each of the end plates, to define, together with the or a spanning plate(s), a hollow rigidifying form, and the hitch assembly is fixably attached directly in part, or indirectly in part, to said angle plate.

1 - 27 . (canceled) 
   
   
       28 . A back hoe bucket assembly comprising or including
 a first end plate or end plate assembly (“first end plate”),   a second end plate or end plate assembly (“second end plate”),   a cutting edge plate from the bottom region of said first end plate to the bottom region of said second end plate so as to provide at least part of the cutting edge of the bucket assembly,   one or more other plates (“spanning plate(s)”) connecting each of said first and second end plates and connecting to said cutting edge plate,   an angle plate or angle plate assembly (“angle plate”) overlying part of said spanning plate(s) between, and connecting directly or indirectly to each of, said first and said second end plates so as to define with part of said spanning plate(s) a hollow rigidifying form across above the cutting edge plate, the exterior angle of the angle plate being upwards,   at least one rib interiorally of said spanning plate(s) distal from both said first and second end plates, and   a hitch assembly fixed in part down onto said angle plate and about part of said spanning plate(s) at least substantially over said at least one rib,   wherein said hitch assembly has pins, or provision for pins, one in advance of and one to the rear of the exterior angle of said angle plate and such pins or provision for pins are mounted to span between upstanding and at least substantially parallel plates set down edgewise over said angle plate.   
   
   
       29 . The back hoe bucket of  claim 28  wherein there are two said ribs and each underlies a plate of said hitch assembly. 
   
   
       30 . The back hoe bucket of  claim 28  wherein the spanning plate(s) are a single plate or at least two plates each of which fully spans from said first end plate to said second end plate and is connected thereto. 
   
   
       31 . The back hoe bucket as claimed in  claim 30  wherein said angle plate is fixed indirectly to said end plates via said spanning plate(s). 
   
   
       32 . The back hoe plate as claimed in  claim 30  wherein said spanning plate(s) acts as a wrap of said end plates and said at least one rib. 
   
   
       33 . The back hoe bucket as claimed in  claim 32  wherein one of said pins or arrangements to receive a pin of said hitch assembly is above the angle plate in advance of the exterior angle of the angle plate and one or more other pins, or provisions for pin placement, are to the rear of said exterior angle of the angle plate. 
   
   
       34 . The back hoe bucket of  claim 28  wherein each end plate is an assembly of plates at least one plate reinforcing to a leading edge or providing the leading edge.
