1 BUILDING APPARATUS, BUILDING SYSTEM AND BUILDING METHOD FIELD OF THE INVENTION [0001] The present invention relates to a building apparatus, a building system and a building method for dispensing a material. The building apparatus, the 5 building system and the building method may be particularly useful for dispensing materials, such as adhesive and/or mortar, when building, for example, a wall from building blocks, such as bricks. BACKGROUND AND PRIOR ART [0002] Walls have been built using mortar and blocks, such as bricks, for 10 many millennia. The mortar is typically placed with the assistance of an instrument, such as a trowel, between the building block so as to space the building blocks and to adhere the building blocks to each other. Such a method has an inherent disadvantage with uneven and wasteful distribution of the mortar. The wastage can be costly and messy. 15 [0003] One prior art device, system and/or method is suggested in U.S. Patent Application Publication No. 2011/0185673, in which a device is used to try to place mortar onto the surface of building blocks. However, this prior art device is constructed with a main supply tube flowing into a "T" intersection, which flows to two side distribution tubes so that mortar can be deposited on two sides of a 20 building block. This construction has a disadvantage in that the flow of mortar (or any other similar binding/adhesive material) is uneven due to the "T" intersection. With such uneven distribution between the two sides of the "T" intersection, the device will produce uneven beads of mortar on either side of the building block. Such uneven distribution is undesirable, creates wastage and can also lead to 25 problems with uneven positioning of a subsequent row of building blocks. Another disadvantage in the device, system and/or method of U.S. Patent Application Publication No. 2011/0185673 is that a user will have difficulty in adjusting the amount of mortar dispensed onto a surface. Configuration of the two side distributions 2 tubes, being vertical, or near vertical when used, may result in only a limited amount of mortar being deposited for a given surface area. Further, it could be difficult to shape the distributed mortar so as to form thicker or higher beads where desired. 5 [0004] Another prior art patent is USA patent 5681125 which discloses a mortar dispenser where the dispensing nozzle has a right angle junction for the incoming mortar and moving parts in the nozzle. This arrangement leads to blocking of the nozzle and deterioration of the dispenser. [0005] The present invention may overcome, or at least ameliorate, at least one of 10 the above-mentioned problems in the prior art, and/or overcome, or at least ameliorate, at least one problem in the prior art, which has not been mentioned above and/or provide at least a useful alternative to prior art devices, systems and/or methods. SUMMARY OF THE INVENTION 15 [0006] In one aspect, the present invention provides apparatus for dispensing mortar onto building blocks, the mortar flowing in its dispensable form and provided to the apparatus under pressure, the apparatus including a longitudinal dispenser head, including a first input port at one end adapted for fluid connection with a source of the mortar, and a pair of output tubes at the other end of said dispenser head, 20 wherein the two output tubes form an angle with respect to, and on opposing sides of a notional vertical plane central of the flow direction, such that the two output tubes form a "V" shape and such that the mortar is able to emerge from the two output tubes . The flow of mortar through the dispenser is essentially linear and avoids any sharp change of angle. 25 [0007] In another aspect, the present invention provides A system for dispensing mortar, the mortar flowing in its dispensable form, the system including: a dispensing apparatus as described above ; and, the source of the mortar, wherein the source includes: a pump suitable for pumping the material in its dispensable form so as to 30 provide the material under pressure to the dispensing apparatus, the pump having a receptacle for accepting the material, a pumping mechanism and an output; and, a flexible conduit, connected at one end to the output and connected at the other end to the dispenser head input. [0008] Preferably the apertures of the at least two output tubes are separated from 3 each other by a distance within the width of a building block. [0009] Preferably the connections on each end of the conduit or hose are releasable connections. 5 SUMMARY OF OPTIONAL EMBODIMENTS OF THE INVENTION [0010] In an embodiment, the angle with respect to the notional vertical plane is between about 300 and 600. In a particular embodiment, the angle with respect the notional vertical plane is about 450.

[0014] In an optional embodiment, the flow path of the mortar from the pump along the hose or conduit to the outlets in the dispensing head avoids any sharp change of direction. [0015] In another optional embodiment, the building block is the group including: bricks, breeze blocks, tiles, and the like. 20 [0016] In yet another embodiment, the plurality of output tubes includes a third output tube intermediate the at least two output tubes.

BRIEF DESCRIPTION OF THE DRAWINGS [0020] For an understanding of the invention and to show how it may be 30 performed, embodiments thereof will now be described with reference to the drawings in which: [0021] FIG. 1 is a perspective view of a building apparatus in accordance with an embodiment of the present invention, wherein the apparatus is used to construct a wall; 4 [0022] FIG. 2 is a perspective view of a system for dispensing a material in accordance with an embodiment of the present invention, where in the system is being used to build a wall; [0023] FIG. 3 is a top plan view of the building apparatus for dispensing a material, 5 in accordance with an embodiment of the present invention; [0024] FIG. 4 is a view of FIG. 3 across line X-X', being a side elevation view of the building apparatus for dispensing a material, in accordance with an embodiment of the present invention; [0025] FIG. 5 is a top plan partial view of the system for dispensing a material, 10 which is shown dispensing mortar/adhesive on to building blocks of width E; [0026] FIG. 6 is a similar view to FIG. 5, but showing building blocks of width F, requiring a building apparatus, in accordance with an embodiment of the present invention, having a width between aperture wider than that shown in FIG. 5. 15 DETAILED DESCRIPTION OF OPTIONAL EMBODIMENTS OF THE INVENTION [0027] FIG. 1 shows an embodiment of a building apparatus 1 for dispensing a material 26, the material flowing in dispensable form and provided the apparatus under pressure. The apparatus includes a dispenser head 10, the dispenser head including at least one port 14 having a distal input 16 adapted for fluid connection 20 with a source 18 of the material. The material is able to emerge or flow from a proximal end of the port in a definite flow direction D. [0028] The dispenser head 10 also includes a plurality of output tubes, in this embodiment being two output tubes 12A, 12B. Each output tube has a distal end 25 in fluid connection 20 with the port 14. Each output tube also has a proximal end for dispensing the material 26. [0029] The connection 20 between the port 14 and each of the two output tubes 12A, 12B, forms an angle with respect to, and on opposing sides of a notional vertical plane central of the flow direction D (refer to FIGS. 3 and 4), such that the 30 two output tubes form a "V" shape. [0030] The "V" shape provides flow characteristics for the material 26, which assists in producing an even flow through both of the two output tubes 12A and 12B. This can be contrasted with uneven flow characteristics produced by prior art devices, which have a "T" intersection between the two output sides of the respective 5 dispensing device and the supply tube of such respective dispensing device. [0031] Also shown in FIG. 1 is a handle 22, which is formed around port 14 and can be gripped by the hand 24 of a user. As such, the presently shown embodiment of the invention is manually operated, but it is envisaged that the invention can be 5 applied to automated material dispensing systems, such as robotic systems. [0032] The source 18 of material 26, in this embodiment, is a hose 48 (see FIG. 2 for more details). In the shown embodiment, the source is a single hose, but could be dual or multiple hoses supplying different material, which can then be combined in the port 14 to form a resultant material, such as an adhesive. Such a dual or multiple 10 input source system could be very useful where using adhesives that need to be mixed at or near the time of dispensing. [0033] FIG. 1 also shows a particular optional embodiment of the two output tubes 12A, 12B, wherein the tubes include proximal tube sections 30A, 30B and distal tube sections 32A, 32B. The proximal tube sections are angled with respect to the 15 distal tube sections so as to be substantially parallel with the notional vertical plane (refer to FIGS. 3 and 4). [0034] The building apparatus 1 is shown dispensing material 26 so as to form two substantially even and substantially parallel beads 28 on either side of building blocks 36. The building blocks 36 forming a wall 38. 20 [0035] As can be seen in FIG. 1, the beads 28 of material 26 are formed on a surface 40, which comprises the top surface of the last layer of building blocks 36 to have been placed in the wall 38. [0036] The building apparatus 1 dispenses the material 26 into the substantially even and substantially parallel beads 28 through proximal apertures 34A, 34B in 25 the output tubes 12 A 1 2 B . [0037] In operation, the apparatus 1 is moved by hand 24 in a direction opposite to the flow direction D. Due to the evenness of flow distribution through each output tube 12A, 12 B which, as previously mentioned, results, at least in part, from the "V" construction of the building apparatus, the beads 28 of material 26 are 30 formed so as to have substantially even shape, volume and/or density. It would be understood by a person skilled in the art that, where the beads of material are referred as being substantially even, this include evenness of shape, volume and/or density. [0038] When operating the apparatus 1, the user is able to hold the apparatus to 6 form an angle M (as shown on FIG. 1) with the surface 40. The size of angle M may be between 300 and 600. By adjusting the angle M, adjusting the speed of flow of material 26 through the apparatus, and/or adjusting the speed at which the apparatus is moved in a direction opposite to D, it is possible to use the apparatus to 5 form beads of differing dimensions. For example, by moving the apparatus 1 more slowly (or increasing flow speed, or both), it is possible to distribute more material per surface area. By positioning the apparatus at a shallower angle M, it is possible to form thicker and/or higher cross-sectional area beads. [0039] It is an optional embodiment to incorporate sliders on the ends of the output 10 tubes 12A/1 2B, the sliders being at a fixed angle M with respect to the respective output tube so as to encourage a user to use the apparatus at the fixed angle M. [0040] It will be appreciated that the surface 40 could be the surface formed by an already-laid layer of building blocks 36, but could be any suitable substrate. Further, the wall 38 could be a masonry wall or a wall constructed from any other 15 suitable building block material. [0041] In FIG. 2, there is shown an embodiment of a system 42 for dispensing a material 26. The system includes a pump 44 including a receptacle 46 for receiving the material 26. It would be understood that the material may be supplied in its dispensable form into the receptacle, such that the material can flow through the 20 apparatus 1 and out therefrom to form beads 28 on the surface 40. However, it is also envisaged that the receptacle 46 could be constructed to receive components of the material, which could then be mixed in the receptacle, manually or automatically, so as to produce the material in its dispensable form. The pump 44 pressurizes the material 26, which is supplied through a hose 48 to the apparatus 25 1. [0042] It will be appreciated that the pressure could be configured so as to be adjustable, which may be useful for altering the flow rate of a given material 26, or to allow the system 42 to dispense materials 26 of differing densities and other characteristics such as differing flow characteristics. 30 [0043] As in FIG. 1, it can be seen that the apparatus 1 is moved in a direction rearward with respect to the user 50, such that the user walks backwards while dispensing material 26 to form the beads 28 on the wall 38. However, it is envisaged that the system 42 and apparatus 1 could be used in a different manner, whereby the user 50 reverses the angle of the apparatus with respect to the surface 40 so 7 that the user 50 can walk in a forward direction to dispense the material 26 on to the surface 40. [0044] The system 42 may be used in a method to construct a wall 38, which is much quicker than traditional laying of, say, bricks and mortar using a trowel to 5 dispense the mortar on to the top surface of a layer of bricks. Using the present system 42 and method, the user 50 may dispense the material 26 into the substantially parallel and substantially even beads 28 quickly. In this regard, with practice, a user can dispense material on a surface 40 efficiently. [0045] In an example embodiment of the method for using the apparatus 1 and 10 system 42, the user quickly dispenses the material 26 to form the two beads 28 on, for example, building blocks such as breeze or masonry blocks. The user (or even another person or group of persons) can then place the next layer of building blocks 36 on the beaded surface 40 to form the now top-most layer of building blocks, which has a new top surface 40. The method can be repeatedly performed until a wall 15 38 is built. [0046] It will be understood that the apparatus, system and method may also be applied to the laying of tiles or brick tiles on a suitable surface or substrate. For example, the apparatus 1 and system 42 could be used to form an intersecting pattern of parallel pairs of beads covering an area of the surface or substrate on 20 which tiles can be quickly placed. This can be much quicker than placing adhesive on each tile individually, but the apparatus 1 could also be used to dispense material onto each tile or brick tile individually. [0047] It will also be understood that the material can be adhesive and/or a mortar. The material can be any other suitable material for building application, such as those 25 described above and below. [0048] It will be further understood that the building blocks 36 can be bricks, breeze blocks, masonry blocks, tiles and any other suitable form of building block, which require material 26, such as mortar and/or adhesive to be applied in a building process. 30 [0049] FIGS. 3 and 4 show an embodiment of the apparatus 1. The material 26 flows through the port 14 in a flow direction D. The flow direction will be understood to have a notional vertical plane 52, which is central of the flow direction D. [0050] In FIG. 3, it can be seen that each of the distal tube sections 32A, 32B of the output tubes 12A, 12B, respectively, form an angle W and W' with the notional 8 vertical plane 52. The angles W/W' can include a range of angles between, for example, about 300 and 600, but may be angles outside that range. A preferred angle is 450. [0051] It will be understood that the angles W/W' are selected so that the two 5 output tubes 12A, 12B form a "V" shape at the connection 20 between the output tubes and the port 14. [0052] In FIG. 4 it can be seen that, in an alternative embodiment, the port 14 can be formed from a distal tube section 54 and a proximal tube section 56. The distal tube section on the proximal tube section of the port 14 can be connected 10 with a threaded connection 58, such that the proximal tube section 56 screws into the distal tube section 54. The handle 22 can be formed around the distal tube section 54. [0053] The distal tube section includes a distal input 16, which can also be a threaded connection, adapted to connect the source 18, or the hose 48 of the 15 source 18. [0054] It will be realized that FIG. 4 is a view of FIG. 3 across the line X-X'. In FIG. 3, the notional vertical plane 52 is viewed from above, and in FIG. 4, the notional vertical plane 52 is viewed from a side. [0055] In FIGS. 5 and 6, it can be seen how the apparatus 1 can be configured 20 for different widths of building block. In FIG. 5, building block 36A has a width E. In FIG. 6, building block 36B has a width F. Accordingly, the separation between the proximal apertures 34A, 34B in the apparatus 1 of FIG. 5 is suitable for dispensing beads 28 of material 26 to be on either side of the building blocks 36A. Similarly, the separation between the proximal apertures 34A, 34B for the apparatus 1 in 25 FIG. 6 is suitable for dispensing beads 28 of material 26 at sides of the building blocks 36B at a distance F. [0056] It is also contemplated that the apparatus 1 and system 42 may include a feature allowing the separation between proximal apertures 34A, 34B to be adjusted as needed for different widths. Such a feature may include forming the output tubes 30 12A, 12B (in part or whole) from a flexible tubular material. It will be understood that such a flexible tubular material will bend under a suitable force, but will retain its shape while being used in the applications contemplated above and below for the apparatus 1 and system 42 and associated methods. In this regard, it will be understood that the flexible material will retain shape under the conditions of 9 having pressurized material 26 flowing there through. [0057] Also shown in FIGS. 5 and 6 is an embodiment of the connection between the source 18 (being the hose 48) and the distal input 16 of the port 14. In the embodiments shown, there is a tap 60, which can be operated to turn the flow of 5 material 28 on and off selectively. [0058] In FIGS. 1, 2, 5 and 6, the wall 38 is shown as being formed by building blocks 36 having a gap between each of the building blocks. However, in some embodiments, the wall may be formed with building blocks not having a gap (or having only an insignificant gap) between them. In other embodiments, the 10 building blocks may be formed so as to have a "key/lock" joining means, so as to interlock adjacent building blocks together. In yet another embodiment, the building blocks may retain a gap, so as to allow the positioning of an expansion/compression material between some or all adjacent building blocks. [0059] It will be understood by a person skilled in the art that the above 15 mentioned invention, its embodiments and variations are just some amongst the many, which are contemplated and contemplatable as being within the scope of the invention as described and as defined in the following claims. [0060] Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as 20 "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. [0061] The reference to any prior art in this specification is not, and should not, be taken as an acknowledgment or any form of suggestion that the prior art forms 25 part of the common general knowledge.
