Title: Concrete Mixer
IPC: B28C5/08
Filed: 1979-08-03
Abstract: To facilitate the compact folding of a concrete mixer during transportation, a foot (4) and a carriage (5) supporting a pair of wheels (6) are each articulatedly connected to a "U"-shaped frame (3), supporting the mixer drum, by a single bolt (9) traversing an elongate inclined hole (8) (or pair of aligned holes (8)), formed at the upper ends of the foot (4) and carriage (5). Figure 3 shows the bolts (9) at the upper ends of the holes (8) when the concrete mixer is lifted to enable the foot (4) and carriage (5) to be folded into the broken line position. The axle (7) supporting the wheels (6) is of "V"- shape when viewed in plan with the apex of the "V" pointing away from the foot (4). Thus, in the folded condition, the "V" embraces the horizontal bar of the frame (3) and the wheels (6) can be disposed higher nearer to the mixer drum. Since the wheels (6) and axle (7) are higher the foot (4) can be folded correspondingly higher beneath the axle (7). In the standing condition, the bolts (9) are at the bottom of the holes (8) and the reaction between the bolts (9) and an inclined side of the holes (8) causes the upper ends of the foot (4) and carriage (5) to be clamped with a wedge-like action against the upright parts of the frame (3). <IMAGE>
