Description

(54) KERB TYPE GULLEY FITTING (71) We, BRICKHOUSE DUDLEY LIMI TED, a British company of Dudley Road West, Tipon, West Midlands, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: - This invention relates to a kerb type gulley fitting or cover intended to be used to provide a kerb and a cover for a drainage channel of a road, the cover being of the type, hereinafter referred to as "the type described" comprising a rear, top and front walls with side walls extending between the front and rear walls at opposite sides of the cover and the front being provided with an opening for passage of water from the road surface to the interior of the cover.

When a kerb type gulley cover of the type described is used in areas where drifting sand is encountered, for example in the Middle Eastern countries, problems are encountered due to entry of sand through the opening in the front wall during the dry season.

It is accordingly an object of the present invention to provide a kerb type gulley cover of the type described wherein the above mentioned problems are overcome or are reduced.

According to one aspect of the present invention we provide a kerb type gulley cover of the type described including a sealing means removably locatable in sealing engagement with the cover to prevent or reduce passage of sand through said opening, the sealing means comprising a plate fixed to a base grid which is engageable with the cover in two alternative positions in one of which the sealing plate is in said sealing engagement and in the other of which said sealing plate permits passage of water through the opening.

When the plate is in said one position, it may be substantially in or adjacent the opening.

In said other position the sailing plate may be disposed at 90" to its orientation in said one position and extend adjacent and parallel to a side wall of the cover.

The top wall of the cover may comprise a lid which is removably mounted on the remainder of the cover.

The lid may be provided with a key operated turnbuckle latch, engageable with an abutment at the rear of the cover and abutment surfaces at the front of the lid which extend downwardly towards the bottom of the cover and which are in abutting relationship with similar surfaces provided at the front of the remainder of the cover whereby engagement of the latch and abutment at the rear of the cover prevents lifting of the rear of the lid and engagement between said downwardly extending surfaces prevents substantial pivotal movement of the lid about the latch and its abutment and hence prevents lifting of the front of the lid.

The gulley cover may be provided with means for receiving and retaining a road retaining bar, and the latch may be a key operated turnbuckle latch provided with a key rotated pivot and means to prevent removal of the key except when the latch is in a predetermined angular position.

One embodiment of the invention will now be described in more detail by way of example with reference to the accompanying drawings wherein: FIGURE 1 is an exploded perspective view of a kerb type gulley cover embodying the invention, and FIGURE 2 is an exploded perspective view to an enlarged scale and partly in section, for a turnbuckle latch of the cover of Figure 1.

Referring now to the drawings a kerb type gulley cover is indicated generally at 10 and comprises a rear wall 11, a removable top wall or lid 12, a front wall 13 and a pair of opposed side walls 14 which extend between the front and rear walls at opposite sides of the cover.

The kerb gulley cover is made as a casting in cast iron and the front, rear and side walls are formed integrally with each other. The front, rear and top walls are arranged in an inverted channel section configuration and provide a cover for a pulley provided beneath the cover as well as providing a kerb for a road alongside which the gulley runs. An aperture 15 is formed in the front wall to permit passage of water from the road surface into the gulley covered by the cover.

The lid 12 is removably mounted on the remainder of the cover and comprises a generally planar upper surface 16 which may be provided with any desired anti-slip pattern of raised areas. On its under surface the cover is provided with a pair of spaced transversely extending reinforcing ribs, indicated diagrammatically at 17 and a median longitudinally extending reinforcing rib, also indicated diagrammatically at 18, as well as a rear edge flange 19.

The lower surface of the flanges 18, 19 rest on support pads 20 formed on the inwardly facing surfaces of the rear, side and front walls.

At the front, the lid 12 has downwardly projecting lugs 21 which have a vertical abutment surface 22a adapted, when the lid is closed, to lie closely adjacent a surface 22b formed at each side of the front wall 13. The lid is also provided at its front with transversely extending cam portions 23 which co-operate with a correspondingly cut away portion 24 of each side wall 14.

At its rear end the top wall is provided with a turnbuckle 28 which, as best shown in Figure 2 is mounted in a boss 26 formed on the under surface of the lid 12. The boss 26 provides a stepped bore 27 in which a bolt 28 is rotatably mounted. The bolt 28 has a square section portion 29 provided on its shank which is received within a square cross section aperture 30 formed in a turnbuckle latch member 31 which is retained on the bolt 28 by means of a locknut 32 or by any other desired means.

The turnbuckle latch member 31 is arranged to engage the under surface 33 (Fig.

1) of a lug 34 which projects inwardly from the rear wall 11 and the upper surface of which provides one of the supporting pads 20 engaed by the rear edge flange 19 of the lid 12.

Referring again to Figure 2, the upper part 35 of the bore 27 is of a diameter slightly greater than that of the head 36 of the bolt 28 and has a pair of diametrically opposed extensions 37.

Between the upper bore part 35 and the lower part of the bore 27 there is an enlarged diameter passage 38 which extends through 90" from each extension 37 to a location, one of which is indicated at 40 in Figure 2 at which the passage 38 is of increased height as indicated at 41.

Beneath the passage 38 slots 42 are formed in the boss at four locations aligned with the positions 40 and the slots 37.

In use of the turnbuckle, a key 43 having a generally stepped T-shaped head 44 with a central recess 45 is engaged with the bolt so that parts of the T-shaped head indicated at 46 engage in slots 47 formed in the head 36 of the bolt 28 whilst outwardly projecting end portions 48 of the head pass through the extensions 37 until they are aligned with the passages 38 thereby permitting the key 43 to be rotated, anti-clockwise, as viewed in Figure 2, to rotate the bolt and hence the turnbuckle latch member 31 out of engagement with the surface 33 to permit the lid to be removed.

When the key 43 has thus been turned through 90" the end parts 48 are aligned with the part 41 of the passages 38 thus providing a retention for the key in said position when the key is utilised to lift the rear end of the cover.

This lifting of the rear end of the cover causes pivotal movement about the engagement between the under surface of the lid and the surfaces 20 at the front of the cover which is permitted by the abutment surfaces 22a and 22b moving apart from each other and thereby permitting removal of the top wall of the cover.

When the latch is engaged with the surface 33 the rear of the cover is thus prevented from being lifted whilst the front of the cover cannot be lifted as to do so would require pivotal movement about the surfaces 20 at the rear of the cover and this would be prevented by engagement of the abutment surfaces 22a and 22b.

It will be appreciated from the above that the key 43 can only be engaged with and removed from the cover when the turnbuckle latch member 31 is engaged with the surface 33.

The slots 42 are provided to permit detritus to be cleared from the interior of the boss as necessary.

It will be noted that when the lid is to be removed the action is to lift the rear by means of the key and then to slide the top wall rearwardlv thus causing the cam portions 23 to slide up the corresponding Cllt- out portion 24 of the side walls thereby lifting the front of the top wall out of engagement with the seatings and thereby permitting the convenient removal of the top wall from the cover.

A slot 69 is- provided in the lid adjacent the front edge to facilitate closing by pulling with a similar key.

The flanges 17 formed on the under surface of the lid 12 extend at their rear ends to project below the surface 19 so as to protect the turnbuckle latch during removal of the cover.

Referring now to Figure 1, at the lower end of the front, rear and side walls a base web 50 is provided at the four corners and a grid 51 comprising a plurality of parallel bars 52 formed integrally at opposite ends with transversely extending bars 53 is received, in use, within the cover to rest on the upper surface of the webs 50. At one end of the grid 51 and formed integrally therewith is provided a vertically upwardly extending sealing plate 54. The grid and sealing plate 51, 54 may be made in any desired manner and may be a casting in cast iron, a metal fabrication or a synthetic plastics moulding, for example.

When it is desired to use the kerb type gulley cover to drain the road surface with which it is associated the grid and sealing plate 51, 54 are located within the cover so that the sealing plate 54 lies parallel to one of the side walls 14.

Alternatively, when it is desired to prevent access of sand to the interior of the gully cover the grid and sealing plate 51, 54 are orientated, as shown in Figure 1, so that the sealing plate 54 extends across the opening 15 in the front wall and the base and side portions of the sealing plate are received within the rebate indicated at 51.

A road retaining bar 60 comprises, referring to Figure 1, a vertical plate 62 from which extend vertical edge and intermediate reinforcing flanges 64, 65 respectively.

An upper rear reinforcing flange 66 is provided which has lugs 67 at opposite ends which, in use, are received in grooves 68 in the side portions of the front wall 13.

The road bar is retained in position in the cover by means of pegs 69 of plastics or other material engaged in apertures, at the top end of the grooves 68.

The road retaining bar is movable upwardly and downwardly within the groove and, in use, is temporarily supported at a desired height until the road has been layed.

Although the gulley cover has been described in the example hereinbefore as being made of cast iron it may be made of other material, for example, as a fabrication in steel or a casting or fabrication in other suitable material.
