  • a fifth preferred form of a handle according to the invention as shown in Figures 7A and 7B r there is provided a moulded handle 16 having a gripping portion 70 and a retaining portion 71. Gripping portion 71 is formed so as to provide a wedge-shaped cavity 72 having apertures communicating with the central portion 73 and the underside 74 of handle 16. Preferably, cavity 72 is wedge-shaped in both length and width. Handle 16 is further provided with a wedge plate 75 adapted for insertion into cavity 72 and so dimensioned as to leave a gap between the surfaces of wedge plate 75 and cavity 72 when assembled as shown in Figure 7B.

  • The. forming of the basin, its depth and hence its other relative dimensions for a given sheet of material is determined by the manner of gathering the material at the four corners prior to the attachment of the handles.
  • the sheet of material is laid out flat on a suitable surface.
  • two points 80 lying equidistant along each of the edges from a corner 8l of the , sheet 82. are initially clamped or weighted down so as to maintain this initial position.
  • two further points 83 and 84- lying along each edge, again equidistant from the corner by approximately at twice the distance as for point 81 and 82, . are pulled together and the material so gathered tied with, for example, a self adjusting cable tie 85.
  • the effect is to draw the material adjoining the tied points upwardly relative to the middle of the sheet thus forming side-like formations surrounding a base portion; in effect approximating a basin.
  • the material lying between, the tied point and the corners may now be gathered for feeding through, and attachment to the handles.
  • material 11 and handles 16 may conveniently be bundled into a suitable container for transport and storage, such as for example in a polythene bag or in a canister such as a paint tin.
  • the device In use the device is spread out on a suitable surface to form the basin 13; typically this will be the floor or ground close to where the mortar or concrete mix is to be used. A bag of dry-mix mortar or concrete is then deposited in the basin. Alternately smaller quantities of ingredients may be placed in the basin as desired.
  • Water ' is then added in the desired or recommended quantity and the mixing process follows according to a first • preferred sequence.
  • Two people each grasp tw.o adjoining handles allowing the bulk of the weight of the ingredients to remain supported on the floor or ground.
  • One person (the first person), commences with either the right or left hand to tug upward on the handle in that hand thus causing the ingredients to be displaced towards the second person.
  • the first person repeats this action with the other hand and then continues the sequence for each hand, tugging • upward and lowering the handles a number of times.
  • the second person now duplicates this procedure. Both persons may continue to alternately repeat the process as required.
  • the mortar or, concrete can be carried in the basin and poured out into its desired location.
  • a single person may effect the mixing process after preparing at -least one but preferably two suitable hooks from a support at the height of approximately one meter and separated (in the case of two hooks) by approximately the width of the basin.
  • mixing may be effected with two handles supported from the one hook, for be-st results, two handles should each be supported by its own hook.
  • the remaining two handles are then grasped by the single person. Again the bulk of th weight .of the ingredients placed in the basin remains supported on the floor or ground as the, single person now alternately raises and lowers his or her two handles.
