The inventionis embodied in the example hereinshown andTdescribed, the'features of vnovelty being finally claimed. e
' In the; accompanying drawings- Figure 1 is a View 1n elevationshowingmy invention applied to a concrete mixing machine in whichthe mixing drum is of the rtating' but non-tilting type, taken at that side of the machine containing and section on the line a ing on a larger scale the pivot bearing or sup xportfor the bucket, looking to the right. F ig.3 is a similar view Fig. 1,illustrating the agitator arm, looking to the right.
Fig. 4 is a-detail. in elevation and section Fig. 1 with,
looking at the left hand side'of parts omitted to avoid confusion. v
In the views the character 5 designates the mixing drumit being'rotated by means of" suitable mechanism driven'bya suitable ens gine at 6, all as usual; At one end the drum has a charging opening as seen at 9.
- .The character designates thecharging bucket, it having side straps ll, 11, connected attheir'forward ends'to a cross bar 12. The
ends of said cross bar project into socket bear-c constitute the pivoting easilyassemble'dlmeansfor the view being on the line III-III,

" bottoms of said. sockets are rounded and 1arg+ erthanthe anti-frictionbearings so that when thebucket is vibrated bypressure in a horizontal' direction the bucket is'also given an up and down movement by said bearing. The i inclined lip atthe lower sideofthe bearing,
