Definitions

  • vent pipes are still fitted on the outside of buildings, and in the United Kingdom, building regulations permit this on buildings up to 3 storeys high.
  • an outside vent pipe usually has to incorporate bends to allow it to pass the guttering at the eaves of the roof. This is expensive, unsightly, and sometimes results in a poorly supported upper part of the vent pipe.
  • the tendency is to provide vent pipes which pass through the slates or tiles of the roof - and this is compulsory where the building is more than 3 storeys high.
  • vent pipe passing through the roof is better design than one carried around the guttering and eaves, but there are problems associated with the weather-proofing of a vent pipe which passes through the slates, tiles or other roof cladding.
  • a soil stack vent pipe which projects through a roof is provided with a weather-proofing lead "slate", which is intended to seal between the pipe and the roof.
  • the lead “slate” has a hole formed in it to receive the pipe and a lead sleeve integral with or fixed to the lead “slate” projects upwardly from the hole, this sleeve being as close a fit as practicable around the outside of the vent pipe.
  • good building practice requires the fitting of a plastics weather collar around the vent pipe immediately above the top end of the lead sleeve, though this is frequently omitted in practice.
  • the apron of the lead “slate” should be fitted below the slate(s) or tile(s) that has been perforated to accommodate the upstanding sleeve of the lead "sleeve", so that at least the lower part of the apron is sandwiched between two slates or tiles. When so fitted, the apron takes over the weather-proofing function of the perforated slate(s) or tile(s).
  • vent pipe sleeve must be vertical when the "slate” is fitted to a roof; but roof pitches vary greatly (from 35° to over 50°) so that it is necessary to manufacture a separate form of lead “slate” and vent pipe sleeve for each roof pitch, and therefore a builder or builders merchant has to stock a variety of lead “slates” which are quite expensive items.
  • lead “slates” which have adjustable angle pipe sleeves, but these are very expensive, and even then are only adapted to accommodate part of the possible range of roof pitches.
  • any lead "slate” support should also be shaped on the top side to follow the contour of the underside of the roofing slate or tile if undulating tiles are used.
  • the lead "slate” method of sealing around the vent pipe includes an uninterrupted vertical joint between the pipe and the lead sleeve which can give rise to water leakage through the roof.
  • a roof ventilator pipe arrangement which includes a rubber apron attached to and surrounding the pipe where it emerges from the roof.
  • the rubber apron is laid on top of the roof and it may be stuck to the roof by the use of asphalt adhesive. This results in much the same unsightly appearance as the lead "slate” and does not comply with the requirement to fit the "slate” below the ordinary slates or tiles of the roof. If on the other hand, the rubber apron is fitted under the tiles or slates of the roof, then it will be unsupported on the underside, unless special support means are manufactured to fit the shape of the roof.
  • DE-B-27 01 383 describes a roof ventilator provided with an "apron" in the form of plastics or galvanised or enamelled sheet metal. This "apron” is to be laid on the slates or tiles of the roof. and therefore has the same problems as the lead "slate".
  • the present invention provides a vent pipe terminal which is generally superior to the lead "slate” construction or the construction described in DE-A-33 21 101 and DE-B-27 01 383 described above. Although reference has been made (and in the specific description will hereinafter be made) to soil pipe vents, it must be understood that the invention is applicable to any kind of vent pipe which passes through the roof of a building.
  • the invention is applicable to the ventilation of soil pipes, flues or rooms (such as internal bathrooms or toilets) and, indeed, it can be used as a ventilator, where there is no ventilation "pipe” as such, excepting that provided by the terminal itself, i.e. if the terminal is fitted to a roof to provide a roof vent for the locked space under the roof.
  • a vent pipe terminal which includes a tubular portion which is intended to extend through the roof of the building, the tubular portion being combined with an apron support extending from the tubular portion to an extent such that it can provide an effective support for a weather-proofing apron located underneath a tile or slate of the roof in a region where, because of the slate or tile arrangement the apron would otherwise be unsupported on the underside (corresponding to DE-A-3321 101), is characterised in that the apron support is made of metal, having a mesh structure so that it is deformable but self-sustaining (i.e. not flexible), whereby, on the one hand, it can be bent to any formation required to enable it to follow the contours of a roof tile but, on the other hand, it will retain that formation.
  • the flexible weather-proofing apron is sealed on to the tubular portion and extends outwardly from all positions around the tubular portion, the apron extending over the whole of the area of the apron support. It is further preferred that the apron is separate from but connected to the apron support. This may be achieved by providing the apron support with a pair of fingers which are received in sockets formed in the tubular portion or a part fastened to the tubular portion.
  • the sockets comprise grooves formed in the tubular portion, the grooves being open at one end to allow the fingers to slide into the grooves.
  • the terminal has an outlet portion extending laterally with respect to the tubular portion, and providing a weather-shielded outlet opening or openings, so that the terminal comprises an elbow, the outlet portion of which lies on top of the roof slates or tiles in use.
  • the outlet portions lies substantially parallel with the top surface of the roof.
  • the elbow-type vent pipe of this invention is deliberately intended to provide an outlet portion which is parallel with the sloping roof.
  • the outlet portion may rest on the roof cladding, but in the majority of cases, it is intended that part of the outlet portion shall be embedded in the cladding.
  • the flexible nature of the apron ensures that it follows the contours of the roof tiles or slates when supported by the apron support. It has been found that an apron made of E.P.D.M. of approximately 3 or 4 mm thickness gives an adequate weather-proofing effect, whilst being flexible enough to allow it to accommodate to a variety of shapes of slates or tiles.
  • the outlet portion comprises an open-topped box and a lid, the lid overhanging the box and an outlet opening or openings formed in the box adjacent to its top edges and therefore close to the underside of the lid when the latter is on the box, the lid having a down-turned lip on its overhanging portions, spaced from the box wall when the lid is fitted to the box, the outlet opening or openings being protected by the overhanging part of the lid and its lip; the inside of the tubular portion communicating with the inside of the outlet portion.
  • the preferred construction of the terminal ensures that the outlet opening or openings is or are shrouded to prevent rain or snow falling into the outlet portion.
  • Figure 1 shows an outer wall 10 of a building having a pitched roof 12.
  • a water closet 14 is shown on the inside of the wall 10, and the soil pipe 16 from the water closet leads through the wall 10 of the building, into a vertical soil pipe stack 18 on the outside of the wall 10.
  • this is a very common arrangement, particularly with older buildings, or modifications to existing buildings, for example where a bathroom is fitted for the first time.
  • Figure 1 also illustrates the opening light 20 of a bathroom window, and current building regulations in the United Kingdom require that if the vent pipe 22 is within 3 metres horizontal distance from the opening light 20 (and of course this is almost inevitably the case) then the open top end of the vent pipe must be at least 900 millimetres above the top of the opening light 20. In a construction such as that illustrated in Figure 1, this necessitates taking the open top end of the vent pipe above the eave 26 of the roof 12.
  • part of the vent pipe 22 has to be offset by the use of offset bends 32 and 34, and a bracket 36 has to be provided to support the offset part of the vent pipe.
  • a tie 38 between the upper part of the vent pipe and one of the roof timbers, although in practice, such a tie is rarely fitted.
  • a weather-proofing lead “slate” 46 (see also Figure 3) is employed.
  • the lead "slate” is essentially a rectangular sheet of lead, usually somewhat larger than a single slate or tile of the roof, and provided with an upstanding lead sleeve 48 which is intended to be a close fit around the outside of the vent pipe 42.
  • the sleeve 48 is soldered to the main portion of the lead "slate" 46.
  • the main part of the lead “slate” 46 is trapped between an underlying tile or slate 50, and a superimposed tile or slate 52, and the upper part of the "slate” 46 is nailed to the batten 54 on which the superimposed tile 52 is hooked.
  • a problem with the lead “slate” is that the sleeve 48 is at a fixed angle relatively to the main portion 46 of the "slate” and this angle is determined by the pitch of the roof. Admittedly, it is possible to bend the main portion of the "slate” 46 to a limited extent, to accommodate slight variation in the pitch of the roof - although such bending can introduce problems including the formation of water collection depressions.
  • roof pitch angles vary from 15° to over 50°, it is necessary for the builder or builders merchant to stock a series of sizes of lead "slates", and this is undesirable, since the lead "slates" are quite expensive in themselves.
  • Figure 2 illustrates the provision of a support 56, which is made in timber, and which is secured to the rafters 40 in order to fill the area in which the lead "slate" would otherwise be unsupported.
  • the timber support 56 has to taper from bottom to top, as clearly shown in Figure 2, in order to accommodate the angle between the superimposed tile or slate 52, and the rafter 40.
  • the top surface of the support 56 should be shaped to the contours of the underside of the tile.
  • FIGS 4 to 9 illustrate a vent pipe terminal and apron combination, provided by the present invention, which as will be hereinafter described, is intended to meet most of the problems associated with the passing of a vent pipe through the roof of a building, and in particular, the weather-proofing and aesthetic problems.
  • the vent pipe terminal 60 is made of plastics material, such as P.V.C. as commonly used for example in the manufacture of guttering and fallpipes for use on buildings. It is to be understood however, that the vent pipe could be made in any material which will withstand weather conditions. Plastics material has been selected, because it is relatively easy to shape, and because it does not corrode.
  • vent pipe 60 is essentially "L" shaped or it could be said to take the form of an elbow, having a straight box cross-section outlet part 62 and a shorter tubular part 68 projecting at right angles from one end of the outlet part 62.
  • the outlet part 62 of the terminal takes the form an open topped hollow box 64 tapering downwardly from a relatively deep top end 66 to a short front end 69.
  • the open topped box 66 may be approximately 270 millimetres in length.
  • All four upstanding walls of the box section 64 are solid imperforate walls, but at the bottom end 69, there are drainage holes 70 formed in the bottom corners of the bottom end wall, to allow moisture to drain from the box 64.
  • the box 64 also has a solid bottom section 72, but a comparatively large rectangular hole 74 is formed in the bottom of the box 64 adjacent to the top end of the box 64.
  • a series of spacing teeth 76 projects from each side wall of the box 64 near to the top edges of those side walls.
  • a lid 80 formed of the same material as the box 64 is provided, and this lid is intended to fit over the open top of the box 64.
  • the lid has a downturned lip 82 all round its periphery, and a series of internally projecting teeth is formed on the inside of the longitudinal sections of the lip 82, these teeth being so located, that each of them rests on a corresponding one of the teeth 76 on the box 64.
  • the inside faces of the lip 82 engage on the outer ends of the teeth 76, to locate the lid laterally with respect to the box 64, and whilst the top end portion of the lip 82 rests against the top end wall of the box 64, the bottom end portion of the lip 82 engages on a single location tooth 86 extending from the bottom end wall of the box 64.
  • the lid 80 is secured on the box 64 by means of a setscrew 88 which engages in a screw-threaded hole in an upstanding spigot 91 formed in the box 64.
  • a series of outlet openings are provided from the interior of the outlet portion 62, each of these outlet openings being formed between the internal teeth formed in the lid, and terminating in downwardly facing openings 90 between the teeth 76 projecting from the side walls of the box 64, and similar openings 92 on each side of the single end tooth 86 at the bottom end of the outlet portion.
  • the lower part of the tubular portion 68 is a plain cylinder, of approximately the same bore as the soil pipe which is to be vented.
  • junction portion 94 which is of generally rectangular shape where it joins the base of the open topped box 64 adjacent to the top end of that box but this section 94 also blends into the cylindrical lower part of the tubular portion 68.
  • the rectangular opening 74 in the bottom of the box 64 opens into the junction portion 94, and hence provides a communication between the bore of the tubular portion 68 and the inside of the box-like outlet portion 62.
  • the entire terminal 60 can be considered to be an elbow having an inlet at the bottom end of the tubular portion 68, and a shrouded outlet around three sides of the rectangular box outlet portion 62. Since there are no obstructions within the terminal, there is thus provision for a free flow of air into and out of any pipe connected to the tubular portion 68.
  • a weather-proofing apron 100 (see also Figure 10) is secured to the vent pipe terminal 60.
  • the weather-proofing apron 100 is made of ethylene-polythene-dienne-molymer (E.P.D.M) and is of approximately 3 millimetres thickness.
  • E.P.D.M ethylene-polythene-dienne-molymer
  • the apron is quite flexible when unsupported, and has approximately the same ability to drape as a rubber mat.
  • the apron is made of E.P.D.M., it is to be understood that it could be made of rubber, synthetic rubber or plastics material.
  • the essential features of the apron are that it must be water-impermeable and moisture-resistant, and that it should have at least some degree of flexibility.
  • the lip 102 is a tight fit around the rectangular upper part of the outlet portion 68, and in fact the apron 100 can only be fitted on to the terminal 60, by distending the lip 102, to pass it over the lower cylindrical part of the tubular portion 68. Once the lip 102 rests on the rectangular part of the tubular portion, it grips tightly on that part. However, it is also preferred to apply adhesive to the interior of the lip 102, so that it seals tightly to the plastics terminal 60 when in position as shown in Figure 5.
  • the apron 100 is also provided with upstanding spigots each of which is a snap fit into one of a pair of holes 106 formed in the base of the box section 64 to assist in securing the bottom part of the apron to the bottom end of the box 64. Moreover, where the apron passes under the base of the box 64, it is preferably secured to that base by adhesive. In other words, steps are taken to ensure that the apron is not only securely attached to the box section 64, but also that it makes a water-tight seal with that section.
  • the top face of the apron 100 is formed with a series of shallow ribs 106, which extend parallel with the side walls of the terminal 60, when the apron is in position on the terminal. Hence, water which might arrive on the top face of the apron will be guided by the ribs 106, downwardly, i.e. from top towards the bottom end of the apron. It will be noted from Figure 10, that the bottom edge of the apron coincides with the bottom end of the box 64.
  • the bottom part of the apron 100 is formed on its underside, with a series of ribs 108 (see Figure 4) which are more substantial than the ribs 106, and which extend at right angles to the ribs 106, that is to say they extend across the width of the apron.
  • the purpose of the ribs 108 is to provide moisture traps against moisture being driven by a wind upwardly across the undersurface of the apron 100.
  • an apron support 120 which comprises a wire mesh grid, formed from a series of longitudinally extending straight stainless steel wire rods 112 bridged by laterally extending rods 114, 116 and 118,the connections between the wires where they cross each other, being effected by welded or soldered joints.
  • the wire mesh grid is rectangular, and is approximately 450 millimetres long and 200 millimetres wide.
  • each of the longitudinally extending rods 122 and 124 on each side of the centre rod 121 is supplemented by an additional longitudinally extending rod which is welded or soldered to the respective rod 122 and 124, to provide two doubled rods.
  • each of the longitudinally extending rods 112 is bent over at 128 to provide a short downwardly extending projection.
  • the apron support 110 is completed by a ring handle 130 which is pivoted on the laterally extending rod 116 between the two fingers.
  • the downwardly extending lip 102 on the apron 100 is formed on the outside of its longitudinally extending parts with triangular ribs 132.
  • the top edges of the ribs 132 are spaced from the underside of the apron 100, to form a groove 134, and this groove is slightly shallower than the thickness of the longitudinally extending rods of the apron support just described.
  • the lateral spacing between the roots of the grooves 134 is approximately equal to the lateral spacing between the reinforced fingers formed by the rods 122 and 124 on the apron support.
  • the fingers on the support are slid into the grooves 134 formed on the apron and this is permitted because the top end of each groove is open.
  • the bottom end of each groove 134 is closed, and this provides a stop for the respective finger, to locate the apron support.
  • the support 120 provides a planar support structure for the top part of the apron 100 above the outlet portion 68 of the vent pipe terminal 60.
  • the top marginal portion of the apron 100 projects above the top edge of the apron support, and of course this portion remains able to flex downwardly.
  • the support 120 can be used to hold the upper portion of the apron 100 against the underside of overlaid tiles or slates in a region where otherwise the apron would be unsupported on the underside.
  • FIG 8 there is illustrated an apron support 150, which is constructed in similar fashion to the apron support 120, excepting that it is much narrower, and comprises only three longitudinally extending rods 152, 154 and 156 (of which the outer rods are duplicated to provide reinforcing) and three laterally extending rods 158, 160 and 162. There is also a ring hook 164 pivoted on the bottom laterally extending rod 162.
  • this apron support has two downwardly projecting fingers on its outer edges, and these are engageable in the grooves 134 on the apron in the same manner as that described with reference to Figure 7.
  • the apron support 150 When the apron support 150 is attached to the apron, it occupies the position illustrated in Figure 15.
  • the total combination of items so far described includes the vent pipe terminal 60, the flexible apron 100, and one of the two apron supports 120 and 150. These are combined as shown in either Figure 10 or Figure 15 depending upon which of the apron supports is selected.
  • the kit of parts needed to provide the vent pipe terminal arrangement also includes a soil pipe adapter 170 illustrated in Figure 9.
  • This is moulded in the same polyvinylchloride material as that used for the vent pipe terminal 60. Essentially, it comprises an upper tubular section 172 and a lower tubular section 174 joined by a flange 176.
  • the upper tubular section 172 is of the same internal and external dimensions as the cylindrical part of the tubular portion 68 of the terminal.
  • the lower tubular portion 174 is bored so that it is a push fit on a soil pipe stack of the kind which has to be vented.
  • the underside of the flange 176 provides an end location for the soil pipe stack, when the adapter 170 is pressed on to it.
  • the kit of parts is completed by a flexible pipe 180 (see for example Figure 24) which is a relatively tight fit on the outside of the cylindrical part of the tubular portion 68 of the terminal 60 at one end, and on the upper tubular portion 172 of the adapter 170 at the other end. It is preferred to secure the pipe 180 to these two tubular portions by worm operated clips (jubilee clips).
  • the flexible pipe 180 is cut to the required length on site as will be hereinafter explained.
  • FIGs 10 to 14 there are illustrated the constructional steps necessary in the fitting of a vent pipe terminal 60 as shown in Figures 4 to 9, in a roof made of single lap concrete slates or tiles 200, 202, 204, 206, 208 and 210.
  • Each of the slates or tiles has its lower end resting on the upper end of a slate or tile in a preceding row of slates or tiles, as can be clearly seen in Figure 10.
  • Each of the slates or tiles has a depending lip 212 across its upper edge, and this lip is hooked on to a batten 214 secured to the rafters (not shown). It will be noted that each of the slates or tiles in one row lies on top of two slates or tiles in a preceding row, the arrangement being such, that half of the lower part of each slate or tile rests on one of the slates or tiles of the preceding row.
  • a rectangular slot 218 is formed through the roofing felt 220, and another rectangular slot 222 is formed in the lower part of the slate 208, which will constitute the superimposed slate appertaining to the fitting of the terminal 60.
  • This slot 222 is just wide enough to accommodate the outlet part 62 of the terminal 60. It will be appreciated, that it is relatively easy to cut a rectangular slot such as that shown at 222 in a slate or tile, because in fact, straight cuts are frequently made on slates during building construction.
  • the location of the slot 222 will be determined so that the bottom end of the outlet portion 62 of the terminal 60 is at a sufficient height above any window or like opening in the building, to comply with regulations.
  • a feature of the present invention is that it is not necessary to attempt to achieve vertical alignment between the slot 222, and the position at which the soil pipe will be located in the bathroom. This in itself facilitates the construction of the vent pipe detail.
  • the row of slates or tiles including the slates 200, 202 and 204 is fitted and secured in the conventional manner as illustrated in Figure 10.
  • a short additional batten 230 is nailed to the rafters just below the batten 215 which is required to support the superimposed row of slates which include the slates 206, 208 and 210.
  • the apron support 120 is fitted to the combined terminal 60 and apron 100 by sliding the fingers of the apron support into the grooves 134 as previously described, until the apron support is in the position illustrated in Figure 10.
  • the upper portion of the apron 100 above the top end of the vent terminal 60 is then folded downwardly over the top of the terminal, as illustrated in Figure 11, to give access to the apron support 120; the latter is placed on the additional batten 230, and the assembly is adjusted to a position, where the tubular portion 68 (or at least the bottom section of the lip 102) surrounding that part of the portion 68, just rests on the top edge of the slates 202 and 204. In this position, the tubular portion 68 will project downwardly through the hole 218 formed in the roofing felt 220. Also, the lower part of the apron 100, which extends on opposite sides of the outlet part 62 of the terminal, will rest flat on the upper parts of the slates 202 and 204. The apron support 120 is then nailed to the additional batten 230.
  • the apron 100 is then unfolded, and the upper part of the apron is laid on the apron support 120.
  • the top edge of the apron 100 extends just above the batten 215, and this top edge can be bent around the top side of the batten 215 if necessary, and in any case, the top part of the apron 100 is secured to the batten 215 by nailing (see Figure 12).
  • a flexible vent pipe 180 (not shown in Figures 10 to 14) is secured to the lower end of the tubular portion 68 of the terminal, and the flexible vent pipe 180 can be connected to the top end of the soil vent stack (not shown in Figures 10 to 14).
  • the outlet portion 62 the only part of the vent pipe terminal which is visible on the outside of the building is the outlet portion 62. This is in any case relatively small compared to the roof, but also lies on the slates 202 and 204 and is partially embedded within the slate 208. Consequently, the projecting part of the terminal is unobtrusive, and if suitably coloured, will not be readily distinguishable, so that there is a great improvement in the appearance of the roof.
  • vent pipe terminal is properly sealed to the roof, because of the following factors:
  • FIGS 15 to 19 show a double lap slated roof, wherein each of the slates 300, 302 and 304 in one row of slates is superimposed on two slates of a preceding row (for instance the slate 302 is superimposed on the slates 306 and 308). It will also be noted, that approximately the top half of each slate is lapped by two superimposed slates, and with this construction, which is conventional, at every position over the roof area, there is at least a double-thickness of slates.
  • a rectangular slot 348 is cut in the roofing felt 349, at a position adjacent to the top side of a batten 314.
  • corner rebates 350 and 352 are cut in a pair of slates 310 and 312 appertaining to a row of slates which is superimposed on the row including the slates 300, 302 and 304.
  • a single rectangular slot 354 is cut in a slate 320 of the row of slates which is superimposed on the row which includes the slates 310 and 312.
  • the apron support 150 (that is the narrow apron support) is fitted to the terminal by sliding its fingers into the grooves 134. In this position, the apron support 150 provides a rigid support for only a central part of the upper region of the apron 100.
  • the support 150 is of approximately the same width as the outlet portion 62 of the terminal 60.
  • the hole 348 in the roofing felt will be aligned with the lower ends of the rebates 350 and 352 as illustrated in Figure 16.
  • the vent assembly is lowered into position, so that the tubular portion 68 passes through the opening 348, and the lip 102 on the apron 100 is received within the rebates 350 and 352. All the lower portion of the apron 100 then rests on the slates 310 and 312, leaving only a relatively short upwardly projecting portion of the apron.
  • the upper end of the apron support 150 rests on a batten 315, which may be an additional batten inserted for this purpose.
  • the upper part of the apron 100 will be folded over the vent outlet terminal as shown in Figure 11, to enable the apron support 150 to be nailed to the battens 316 and 315, and then the apron is unfolded, its top edge is bent around and nailed to the batten 315, and the top portion of the apron 100 is nailed to the batten 315 as illustrated in Figure 17.
  • the outlet portion 62 of the vent pipe and the lower part of the apron 100 rests on the slates of the row of slates below the vent pipe fitting.
  • the upper row of slates including the slate 320 is then fitted, and the slate 320 is nailed to the batten 316, the nails passing through the apron 100, and further securing the apron in position.
  • the appearance of the roof after the terminal 60 has been fitted is illustrated in Figure 19.
  • the construction illustrated in Figures 15 to 19 gives all the advantages previously mentioned in relation to the construction illustrated in Figures 10 to 14.
  • the narrow apron support 150 is used, because only a relatively small area of the apron 100 lies over an "unsupported" region of the roof.
  • FIGs 20 to 23 there is illustrated a method of fitting a vent pipe terminal in accordance with the invention, to a roof comprising single lap interlocking profiled tiles.
  • the tiles 400 and 402 of one row are superimposed on the tiles of a preceding row, including the tile 404, and the overlap is relatively small and similar to the overlap of the single lap slates illustrated in Figures 10 to 14.
  • the principal difference between the roof construction illustrated in Figures 20 to 23 and that illustrated in Figures 10 to 14, is that the tiles 400, 402, 404 have longitudinally extending undulations to enhance the appearance.
  • Each tile has a lip 406 along its top edge, which hooks on to a batten 414 to retain the tile in position on the roof.
  • a rectangular opening 418 is formed in the roofing felt 420 adjacent to the top edge of the last laid row of tiles, to accept the tubular portion 68 of the vent terminal as in the previously described arrangements.
  • the larger apron support 120 is fitted to the apron and terminal combination, and a short additional batten 430 is fixed to the rafters of the roof.
  • the tubular portion 68 of the terminal is then pushed through the opening 418 in the roofing felt, and the lower part of the apron 100 rests on the undulating top surface of the tiles 400 and 402, and the outlet section 62 is pressed down into position between two of the upwardly projecting undulations on the tiles.
  • the outlet portion occupies a position between the undulation at one end of the tile 400, and the first undulation on the tile 402.
  • the top part of the apron 100 is folded over the outlet portion as illustrated in Figure 11, to give access to the apron support 120.
  • the latter is nailed to the batten 430, and then the apron 100 can be unfolded, and its top portion secured by nailing to the batten 415 as shown in Figure 21, and in similar fashion to the securing method described with reference to Figure 12.
  • a tile 408 (see Figure 22) of the next succeeding row of tiles is formed with a side notch wide enough to receive the width of the box-like outlet portion 62 of the terminal 60, and in practice, the side notch must be wide enough to allow for a mortar bed 440 illustrated in Figure 22, of approximately the same width as the lip arrangement 442 provided along the edge of the tile 408 for engagement with the next tile.
  • the mortar bed 440 is applied, and then the next succeeding tile 410 can be placed in position, so that it engages with the lip arrangement 442 on the tile 408, it also engages with the side walls of the outlet portion 62 of the terminal, and it beds into the mortar 440.
  • the lower portion of the apron 100 will project from the superimposed tiles 408 and 410 (see Figure 23) but if desired, this projecting part of the apron can be cut away.
  • the terminal 60 is then neatly sited on the roof tiles, and an effective weather-proofing seal is provided by the apron 100, which in the "unsupported" region, has the benefit of support from the rigid apron support 120.
  • the ring handle 130 or 164 is used by the fitter, to hold the terminal 60 down on the slates or tiles, to prevent it being displaced upwardly, when the end of the flexible vent pipe 180 is being forced over the tubular portion 168 of the vent terminal.
  • FIG 24 there is shown part of a cavity wall 500 surmounted by a slated roof 502.
  • a soil vent pipe stack 504 is secured to the outside of the wall 500, and occupies a position very similar to that of the vent pipe 18 illustrated in Figure 1.
  • the vent pipe terminal is that which is illustrated in Figure 1, which involves carrying the vent pipe around the eave and guttering 506 of the building.
  • Figure 24 shows the fitting of a vent pipe terminal 60 in accordance with the present invention at a position on the roof 502 which is sufficiently high on the roof, to ensure that even the bottom end of the outlet portion 62 of the terminal 60 is the required height above any window or door opening in the wall 500.
  • the flexible vent pipe 180 is attached at its upper end to the tubular portion 68 of the terminal 60 on the underside of the roofing felt 508, and the vent pipe is then carried under the rafters of the roof, through the space between the roof and the top end of the cavity wall 500, where it is attached to the top end of the vent pipe 504.
  • Figure 24 illustrates the neatness of the arrangement.
  • the flexible vent pipe 180 in effect extends the vertical vent stack 504 to the underside of the roof, and to a location such that when the terminal 60 is fitted, any regulations governing the distance between the terminal and openings in the wall of the building are met.
  • FIG 25 there is illustrated another arrangement, in which the top end of a cavity wall 550 is shown. Part of the roof 552 of the building is also illustrated, and in this case, a vertical soil stack pipe 554 is fitted closely adjacent to the inside of the wall 550. With this arrangement, the pipe 554 will probably be secured to the inside of the wall 550.
  • a vent pipe terminal 60 in accordance with the invention is fitted to the roof 552 at a sufficient height to comply with any venting regulations.
  • This arrangement illustrates the employment of a standard plastics elbow 556 which is pressed on to the tubular portion 68 of the terminal 60, the flexible pipe 180 being attached at one end to the elbow 556, and at the other end to the top end of the vertical vent stack 554. Again, from the outside of the building, the only venting feature which is visible is the terminal 60.
  • Figure 26 illustrates another arrangment, in which there is a cavity wall 600 and a roof 602.
  • a vertical soil vent pipe 604 is located adjacent to the outside of the wall 600 and in this arrangement, the terminal 60 is fitted to the roof at a considerable distance from the top end of the vent pipe 604.
  • an elbow 606 is fitted to the tubular portion 68 of the terminal, and then a straight rigid polyvinylchloride pipe 608 is fitted to the elbow 606.
  • the flexible vent pipe 180 extends the straight plastics pipe 608 and the top end of the vertical soil vent pipe 604.
  • Figure 27 illustrates part of a roof of a building 650 adjacent to the ridge tiles 652.
  • a vertical soil vent pipe 654 inside the building is well away from the outer wall (not shown) so that it is near to a vertical projection of the ridge of the roof.
  • the terminal 60 is fitted to the roof 650 as previously described, and the flexible vent pipe 180 is fitted between the tubular portion 68 of the terminal and the top end of the pipe 654. Most of the flexible vent pipe 180 is vertical, but its top end is turned through an angle to enable it to fit on to the tubular portion 68 of the terminal.
  • the angle of inclination of the terminal to the horizontal is always determined by the pitch of the roof.
  • the tubular portion 68 will always extend at 90° to the pitch of the roof.
  • variations in the angle of pitch of the roof can always be accommodated.
  • the apron 100 always lies substantially in the same plane as the base of the outlet portion 62 of the terminal, and there is no question of bending the apron relatively to the outlet portion. Localised bending of the apron is only required in order that it fits snugly against the slates or tiles with which it seals.
  • the outlet portion 62 the only part of the terminal arrangement which is visible on the outside of the building is the outlet portion 62. If this is made in a neutral colour such as black or grey, then it will be useable with a variety of coloured roofs. However, for some purposes it may be desirable to have the outlet portion, including the lid, coloured to match the colouring of the roof slates or tiles.
  • Another possibility is to manufacture the main portion of the terminal, that is to say the box of the outlet portion and the tubular portion 68 in a neutral colour, but to provide a variety of lids in different colours to match different colours of tiles.
  • the terminal When the terminal is in position on the roof of a building, it is mainly the lid which is visible, and the sides of the outlet portion appear only as outlines to the lid. Therefore, if the lid itself is coloured to match the tiles, the overall appearance will be that the terminal is in a colour matching the tiles.
  • the lid of the terminal in the same ceramic material as the roof tiles themselves. This of course ensures that the colour of the lid is identical with the colouring of the tiles.
  • the lid may then be made in two parts. One of these is the ceramic portion which provides the top surface and the overhanging parts of the lid, but this portion is simply in the form of a rectangular dish.
  • a moulded plastics frame is provided which is a tight fit within the ceramic portion of the lid, and the moulded plastics frame has the formations including the internally projecting teeth to provide the special outlet arrangement of the terminal.
  • the terminal 60 is fitted to the roof in any of the ways described with reference to Figures 10 to 23 of the drawings.
  • the flexible pipe is not used, and the open end of the tubular portion 68 which projects into the loft space provides the ventilator inlet, the outlet being provided by the outlet portion 62.
