Definitions

  • This invention relates to mixing machines such as are used in the production for building and constructional or other work, of concrete and other mixtures.
  • the mixer unit should preferably be adapted to be swung around in either direction.
  • the mixer unit normally, is incapable of being swung round bodily, as aforesaid, in a horizontal direction, until it has been lifted or jacked up. When it has been swung to the desired position it may then be restored to its normal position of contact with the chassis and may be locked tightly thereto.
  • a mixing machine in which the mixer unit is adapted V to be swung round bodily in a horizontal direction upon the chassis, a vertical shaft interconnecting the mixer unit and the chassis, said shaft preventing relative vertical movement therebetween, and roller and track means for permitting frictionless rotation.
  • Conical rollers, for instance, mounted on the chassis may run upona conical circular track provided on the mixer unit.
  • member secured to the mixer unit may be arranged to permit of its locking engagement with the chassis.
  • Such member may MIXING MACHINE 307,436, and in Great Britain October 6, 1927.
  • a mixing machine in which the mixer unit is adapted to be swung round bodily in a horizontal direction upon the chassis, a vertical shaft interconnecting the mixer unit and the chassis, which shaft is capable of producing a relative vertical movement therebetween by reason of its being screwed into the chassis and having fixed thereto a collar which supports the mixer unit when it is being swung round into a desired position.
  • Thechassis may have secured thereto a bearing containing a screwed bush, which bush is adapted to accommodate the screwed end of said shaft.
  • a collar keyed to the shaft and provided with holes will enable the shaft to be rotated by means of a tommy bar.
  • Pads may be fixed to the mixer unit so that when the latter has been swung round into a required position said shaft may be screwed down until these pads bind or lock with the chassis.
  • Fig. 1 represents one form of our invention in which constant distance between the chassis and the mixer unit is maintained;
  • Fig. 2 represents another formof our invention in which the distance between the chassis and the mixer unit is variable;
  • Fig. 3 represents in diagram form a general lay-out of a mixing machine incorporating the arrangement shown in Fig. 2.
  • shaft 1 interconnects the'two channel bearers 2 of the mixer unit and the two channel bearers 3 of the chassis, and conical rollers 4 mounted on shafts 5 and fitted to the chassis run upon the conical circular track 6.
  • Four rollers altogether are provided, two only however are shown in Fig. 1.
  • Plate 7 fixed to one of the bearers 2 is bolted to the chassis after the mixer unit has been swung round into the desired position, bolt hole 8 being provided for this purpose.
  • the arrangement of the bearers 2 and the bearers 3 with regard to the complete mixing machine may easily be understood upon reference to Fig. 3, two
  • parallel bearers 3 being suitably secured to the road wheels 9.
  • Two parallel bearers 2 carry the complete mixer unit which includes the engine (not shown), mixing drum '10, chute 11, and two triangular supporting frames 12.
  • the shaft 1 is screwed into bush 13 contained in bearing 14 secured to. the chassis.
  • Rotation of the shaft 1 is obtained by means of a tommy bar 15 inserted into holes formed in collar 16 which is secured to the shaft 1 by the key 17.
  • the mixer unit is carried to its raised position by means of three collars 18, 19 and 20, collar 20 being secured to the shaft 1 by means of pin 21.
  • Pads 22 fixed to the mixer unit enable it to be locked firmlyto the chassis after the same has been swung into the desired position.
  • the threads on shaft 1 are thus reli oVQd of the weight of the mixer unit. Thislocking as will be understood is obtained by rotation of'the tommy bar in a clockwise direction assuming the threads on the shaft 1 to be right handed.
  • a mixing machine comprising a mixer unit and means for rotatably supporting the same on a vertical axis comprising bearer members one above the other, the lower bearer member being part ofachassis,the upperbearor being rotatable with the mixerunit relative to the chassis bearer, a vertical shaft extending between and connecting said bearers, in a centralposition, and means to prevent unintentional rotation of the mixer unit with its bearer.
