- the present invention not only controls the fluid flow into the entrance of a water diversion system, but also senses the nature and extent of contaminants contained within the fluid.
- the apparatus comprises an elongated, yieldably deformable support in the form of a cable under tension that substantially spans the fluid flow channel and a plurality of transversely spaced apart flow control vanes that are connected to the cable.
- the flow control vanes function to control fluid flow through the curbside drain and work in tandem to block the entry of unwanted debris into the storm drain.
- the flow control vanes are pivotally movable between a first at rest position and a second position wherein an increase in fluid flow through the fluid flow channel is permitted.
- the system further includes a mechanism for controlling the tension in the elongated, yieldably deformable support cable and thereby controlling the resistance that is offered by the system to the flow of fluid through the fluid flow channel and the entry of objects into the storm drain.
- the system of the present invention not only controls the fluid flow into the entrance of a water diversion system, but also senses the nature and extent of contaminants contained within the fluid flowing into the water diversion system.
- this contamination sensing function is accomplished by providing each of the flow control vanes with sample collection assembly that comprises a collection container and a sample collecting media.
- the sample collecting media comprises a material capable of removing from the fluid flowing through the fluid flow channel contaminants selected from the group consisting of hydrocarbons, including fertilizers and wastes from humans and animals, heavy metals and pesticides.

- Another object of the invention is to provide an apparatus of the aforementioned character that effectively prevents the entry of unwanted debris into curbside storm drains during conditions of low to moderate rainfall, but may permit the free entry of debris into the storm drain during conditions of heavy rainfall.
- Another object of the invention is to provide an apparatus of the class described that can be specially tailored to accommodate directional fluid flow as, for example, downhill fluid flow.
- Another object of the invention is to provide an apparatus of the described in the preceding paragraph which, because of its unique design, cannot jam and will automatically open to permit fluid flow through the flow control channel when the flowing water impinges upon control vanes.
- Another object of the invention is to provide an apparatus as described in the preceding paragraphs that is easy to install and in no way affects the structural integrity of the storm drain.
- Another object of the invention is to provide an apparatus of the class described in which the flow control vanes of the apparatus can be readily modified for use in storm drains of varying height and width.
- Another object of the invention is to provide an apparatus of the class described in the preceding paragraph which, because of the unique design of the lightweight flow control vanes of the apparatus, permits a significantly higher flow volume of water through the fluid flow channel than is permitted by prior art devices embodying perforated flow control gates.

- FIGS. 1 and 2 one form of the fluid flow control, analysis and debris intercepting apparatus of the invention is there shown as it appears when positioned within a storm drain opening.
- This embodiment of the apparatus which is generally designated in the drawings by the numeral 12 , functions to control the flow of fluid and the introduction of debris into the opening “O” of the storm drain “SD” that comprises a structure “S” having spaced apart side walls “W” that define the opening “O” through which fluid, such as rainwater flows.
- this embodiment of the invention also uniquely includes a plurality of sample collection assemblies 14 that are connected to uniquely configured flow control vanes 16 , the construction and function of which will be described in greater detail in the paragraphs which follow.
- each of the collection assemblies comprises a collection container 18 and a sample collecting media 20 .
- Collecting media 20 can be made up of a wide variety of materials, but preferably comprises a material selected from the group consisting of activated carbon, polypropylene and absorbent cellulose.
- the apparatus 12 comprises a support member 22 to which the flow control vanes 16 are pivotally connected.
- Support member 22 which comprises an elongated, generally cylindrically shaped pivot rod having first and second extremities 22 a and 22 b ( FIG. 4 ), is connected to side mounting members 24 , which are in turn connected to structure “S” in the manner shown in FIG. 1 of the drawings.
- each of the flow control vanes 16 uniquely function to control fluid flow through the fluid flow channel and to selectively block the entrance of debris into the channel.
- each of the flow control vanes 16 has a front face 16 a, a rear face 16 b, an upper portion 16 c, an intermediate portion 16 d and a lower extremity 16 e.
- the upper portion 16 c of each of the flow control vanes is provided with a transverse bore 26 that is constructed and arranged to slidably receive the support member 22 .
- the front face of each of the flow control vanes is provided with a generally U-shaped groove 28 that is adapted to slidably receive a guide member 30 having a transverse bore 30 a ( FIG. 7 ). Groove 28 is also adapted to slidably receive the mounting column portion 18 a of each of the collection containers 18 of the collection assemblies 14 .
- an elongated, biasing member shown here as an elongated, yieldably deformable biasing cable 40 ( FIGS. 2 and 4 ) having a first end 40 a and a second end 40 b. Cable 40 is received within openings 30 a formed in the guide members 30 (see FIG. 7 ). Cable 40 uniquely functions to controllably resist movement of the vanes toward their second position. In a manner presently to be described, cable 40 is continuously maintained in tension and the degree of tension in the cable is regulated by a novel tensioning mechanism 42 that is carried by the structure “S”. As best seen in FIGS.
- this important tensioning mechanism here comprises a hollow housing 44 , a cable retaining cup 46 disposed within housing 44 for rotation with respect thereto and a finger engaging ratchet wheel 48 connected to the housing for rotation with respect thereto.
- finger engaging ratchet wheel 48 has a peripheral portion 48 a provided with a multiplicity of circumferentially spaced apart teeth 48 b and a central stem 48 c that extends outwardly therefrom.
- Stem 48 c extends through the central opening 50 a of a conventional torsion spring 50 that is mounted within cable retaining cup 46 .
- Torsion spring 50 has a first end 50 b that is connected to the cable retaining cup 46 and a second end 50 c that is connected to finger engaging ratchet wheel 48 .
- the end of the biasing cable 40 can be fed through the receiving slot 54 formed in the housing 44 in the manner shown in FIGS. 10 and 11 .
- the end of the biasing cable can be fed through the receiving slot 46 a formed in the cable retaining cup 46 and suitably interconnected with the cable retaining cup.
- tension can be applied to the biasing cable 40 by grasping the finger engaging bar 48 d of the ratcheting wheel and rotating the ratcheting wheel 48 against the urging of torsion spring 50 .
- a ratchet release pawl 56 is pivotally connected to housing 44 in the manner illustrated in FIG. 11 of the drawings.
- the ratchet release pawl is movable between a first position wherein the teeth 56 a on the pawl engage the teeth 48 b preventing rotation of said finger engaging ratchet wheel and a second position permitting rotation of said finger engaging ratchet wheel.
- a conventional coil spring 58 functions to releasably maintain the release pawl in its first position.
- the cable 40 is first tensioned in the appropriate manner by rotating the finger engaging knob 48 of the tensioning mechanism, which is operably associated with spring 50 .
- the control vanes will tend to move in the manner shown in FIGS. 3 and 4 of the drawings.
- the cable will yieldably resist the movement of the control vanes. It is apparent that the degree of tension placed on the cable 40 controls the amount of force that must be imparted on the control vanes by the flowing fluid to move the cable into the configuration shown in FIG. 4 .
- the greater the tension on the cable 40 the greater is the force against the fluid flowing through the storm drain “SD” and impinging on the control vanes that is required to move the cable into an arcuate configuration as is illustrated in FIG. 4 and to move the control gate into an open position. Conversely, the lesser the tension on the cable 40 , the lower is the force against fluid flowing through the storm drain “SD” and impinging on the control vanes that is required to move the control gate into an open position.
- a lesser tension is placed on the cable 40 so that the control gate can open widely to permit maximum fluid flow and also to permit debris, such as plastic bottles and the like that may build up against the control gate to flow freely into the storm drain.
- the collection container 18 of each of the collection assemblies of the invention comprises interconnected front and side walls 60 and 62 which include vertically spaced apart slats 64 .
- a top wall 66 Connected to and spanning side walls 60 and 62 is a top wall 66 .
- mounting column 18 a Connected to top wall 66 and extending upwardly there from is the previously mentioned mounting column 18 a that is generally T-shaped in cross-section.
- the sample collecting media 20 which is disposed within the collection container, is held in position by a rear wall 70 that includes vertically spaced apart slats 72 .
- top wall 66 Connected to the rear wall 70 and extending outwardly there from is the top wall 66 that is provided with a generally T-shaped opening 66 a through which mounting column 18 a is slidably received in the manner shown in FIG. 6 . It is to be observed that the spaced apart slats 64 and 72 provided on the walls of the collection container define a plurality of fluid ports that permit fluid flow into the connecting container in a manner to uniformly wet the collecting media 20 that is disposed within the container.
- each of the collection assemblies 14 is slidably received within the generally U-shaped groove 28 formed in the front face of each of the flow control vanes 16 .
- the collection containers and the sample collecting media 20 disposed there within is strategically positioned in the path of the wastewater flowing through the fluid flow channel.
- FIG. 9 of the drawings an alternate form of collection assembly and sample collecting media of the invention is there shown.
- This form of the collection assembly and sample collecting media which is designated by the numeral 77 , is similar in construction and operation to the embodiment shown in FIGS. 5 through 8 . However, as indicated in FIG. 9 , it is of a greater length so that it can be more effectively used in flow channels of greater depth.
- FIG. 12 of the drawings still another form of the fluid flow control and debris intercepting apparatus of the invention is there shown as it appears when positioned within a conventional curbside storm drain.
- This form of the apparatus which is generally designated in the drawings by the numeral 80 , functions to control the introduction of fluid and debris into the entrance of a conventional storm drain.
- Apparatus 80 is similar in many respects to the embodiment of the invention shown in FIGS. 1 through 8 and like numerals are used in FIG. 12 to identify like components.
- the primary difference between this latest form of the invention and that of the previously described invention resides in the provision of tensioning mechanisms that are of a different construction and operation from the tensioning mechanisms 42 of the embodiment of the invention shown in FIGS. 1 through 8 .
- the apparatus includes a plurality of sample collection assemblies 14 that are connected to uniquely configured flow control vanes 16 , which are, in turn, pivotally connected to a support member 22 .
- Support member 22 is connected to side mounting members 24 , which are connected to structure “S” in the manner shown in FIG. 1 of the drawings.
- the front face of each of the flow control vanes is provided with a generally U-shaped groove 28 that is adapted to slidably receive a guide member 30 having a transverse bore 30 a ( FIG. 7 ).
- Groove 28 is also adapted to slidably receive the mounting column portion 18 a of each of the collection containers 18 of the collection assemblies 14 ( FIG. 5 ).
- An elongated, yieldably deformable biasing cable 40 having first and second ends 40 a and 40 b is received within openings 30 a formed in the guide members 30 (see FIG. 7 ).
- Cable 40 functions to controllably resist movement of the vanes toward their second position and is continuously maintained in tension by swivel connector assemblies 82 that are mounted on side mounting members 24 .
- the ends 40 a and 40 b of cable 40 are securely connected to connector assemblies 82 by a suitable means. More particularly, the cable end portions are connected to an angle bracket 84 that is rotatably connected to the side mounting members 24 by a threaded connector 86 .
- FIGS. 13 and 14 of the drawings yet another form of the fluid flow control and debris intercepting apparatus of the invention is there shown.
- This form of the apparatus which is generally designated in the drawings by the numeral 90 , is similar in many respects to the embodiments of the invention shown in FIGS. 1 through 8 and 12 and like numerals are used in FIGS. 13 and 14 to identify like components.
- the primary differences between this latest form of the invention and that of the previously described invention resides in the absence of the sample collection assemblies and the provision of a totally different biasing mechanism for controlling movement of the vanes toward their second position.
- the apparatus comprises a plurality of uniquely configured flow control vanes 16 , which are pivotally connected to a support member 22 .
- Support member 22 is connected to side mounting members 24 , which are in turn connected to structure “S” in the manner shown in FIG. 1 of the drawings.
- the front face of each of the flow control vanes is provided with a generally U-shaped groove 28 that is here adapted to slidably receive a guide member 92 having a transverse bore 92 a.
- tensioning member here provided as an elongate tension spring member 94 having first and second end portions that are secured to side mounting members 24 by means of novel swivel connector assemblies 96 .
- Tension spring members 94 are readily commercially available from various sources including the Jones spring Co. Inc. of Wilder Ky. These spring members, which can be provided in various diameters ranging from 1 ⁇ 8 to 3 ⁇ 8 inches in diameter, have proven to be suitable for the purposes of the present invention.
- each of the swivel connector assemblies 96 which connect the spring members to the side mounting members 24 , include an angle bracket 98 the first leg 98 a of which is rotatably connected to the mounting member 24 by a threaded connector 86 and the second leg 98 b of which extends perpendicularly outward from the mounting member ( FIG. 14 ).
- the ends of the tension spring member 94 are removably connected to the second leg 98 b of the angle bracket by any suitable means such as elongate threaded studs 100 and mating connector nuts 102 and 102 a. More particularly, as best seen in FIG.
- threaded studs 100 have a first end connected to the tension spring member and a second end connected to the angle brackets by means of the connector nuts 102 and 102 a.
- the degree of tension in the spring member is regulated and controlled by the swivel connector assemblies as the first legs 98 a of the angle brackets rotate relative to the side mounting members 24 due to the movement of the control vanes out of plane and toward their second positions as a result of liquid flowing through the flow channel (see FIG. 4 ).

- The present invention relates generally to storm water control systems. More particularly, the invention concerns a storm water gate for controlling the flow of fluid and the introduction of debris into the entrance of a water diversion system and for sensing the nature and extent of contaminants contained in the fluid.
- The control of excess runoff rain water has long been a problem faced by municipalities throughout the civilized world. Heavy rainfall can create large volumes of runoff that must be handled effectively in order to avoid flooding, that can result in road closures and substantial property damage. Accordingly, most municipalities have installed drain systems that include curbside drains that are provided at spaced apart locations along most thoroughfares. The curbside drains typically lead to main drain pipes that carry the water to adjacent rivers, directly to the ocean, or to remote catch basins.
- While the prior art drain systems have, for the most part, proven effective in carrying runoff storm water away from the streets and populated areas, the control of man-made and natural debris entering the drain systems remains a major problem. For this reason, various attempts have been made in the past to prevent unwanted debris from entering into curbside drains. These prior art attempts have included placing plates over the drains that are specially configured to trap the debris and still provide limited space for the water to flow. This approach has generally proven unsatisfactory because, as a general rule, the drains cannot adequately accommodate the runoff during heavy rainfall events. Other attempts have been made to design curbside drain gates that remain closed during dry periods, but open during moderate to heavy rainfall events.
- A novel and highly successful fluid flow control and debris intercepting apparatus is described in U.S. Pat. No. 8,535,523 in which the inventor of the present application is named as a co-inventor. The present invention, which is an improvement over the invention disclosed in the U.S. Pat. No. 8,535,523 patent, not only controls the fluid flow into the entrance of a water diversion system, but also senses the nature and extent of contaminants contained within the fluid. Because of the pertinence of U.S. Pat. No. 8,535,523, this patent is hereby incorporated by reference as though fully set forth herein.
- U.S. Letters Pat. No. 3,945,746 issued to Bredbenner illustrates another prior art approach to wastewater flow control and discloses a specially configured catch basin curb inlet opening cover that comprises a rectangular grating panel that is adapted to be supported in a stationary frame surrounding and opening of a storm drain inlet. U.S. Pat. No. 7,611,304 issued to Lill et al. illustrates another prior art approach to providing a specially configured catch basin curb inlet opening cover.
- U.S. Pat. No. 7,234,894 issued to Flury discloses an automatically openable and closable gate system for use with street side curb openings that includes a gate which during dry and low flow water drainage situations is in a closed position and during periods of heavy rainfall will automatically open. U.S. Publication No. 2008/0226390 discloses a system that is somewhat similar to the Flury system and includes an automatic fluid channel screen lock-unlock system for automatically locking and unlocking a screen that is disposed within a fluid channel wherein the screen is rotatable relative to the channel from a closed position to an open position.
- By way of brief summary, the present invention comprises a fluid flow control and debris intercepting apparatus for controlling the flow of fluid and the introduction of debris into the entrance of a conventional curbside storm drain of the character having spaced apart side walls that define a fluid flow channel through which fluid flows. However, the present invention not only controls the fluid flow into the entrance of a water diversion system, but also senses the nature and extent of contaminants contained within the fluid.
- In one form of the invention the apparatus comprises an elongated, yieldably deformable support in the form of a cable under tension that substantially spans the fluid flow channel and a plurality of transversely spaced apart flow control vanes that are connected to the cable. The flow control vanes function to control fluid flow through the curbside drain and work in tandem to block the entry of unwanted debris into the storm drain. To accomplish this purpose, the flow control vanes are pivotally movable between a first at rest position and a second position wherein an increase in fluid flow through the fluid flow channel is permitted. The system further includes a mechanism for controlling the tension in the elongated, yieldably deformable support cable and thereby controlling the resistance that is offered by the system to the flow of fluid through the fluid flow channel and the entry of objects into the storm drain. Additionally, the system of the present invention, not only controls the fluid flow into the entrance of a water diversion system, but also senses the nature and extent of contaminants contained within the fluid flowing into the water diversion system. In one form of the invention, this contamination sensing function is accomplished by providing each of the flow control vanes with sample collection assembly that comprises a collection container and a sample collecting media. Preferably, the sample collecting media comprises a material capable of removing from the fluid flowing through the fluid flow channel contaminants selected from the group consisting of hydrocarbons, including fertilizers and wastes from humans and animals, heavy metals and pesticides.
- With the forgoing in mind, it is an object of the present invention to provide an apparatus that effectively controls the flow of fluid and the introduction of unwanted debris into the entrance of a curbside storm drain.
- Another object of the invention is to provide an apparatus of the character described that senses the nature and extent of contaminants contained within the fluid flowing into the water diversion system.
- Another object of the invention is to provide an apparatus as described in the preceding paragraph that functions to sense contaminants contained within the wastewater selected from the group consisting of hydrocarbons, including fertilizers and wastes from humans and animals, heavy metals and pesticides.
- Another object of the invention is to provide an apparatus of the aforementioned character that can readily be installed by unskilled workmen in storm drains of varying standard and nonstandard construction, including curbside storm drains and storm drains provided in temporary concrete highway barriers such as “K rails”.
- Another object of the invention is to provide an apparatus of the aforementioned character that effectively prevents the entry of unwanted debris into curbside storm drains during conditions of low to moderate rainfall, but may permit the free entry of debris into the storm drain during conditions of heavy rainfall.
- Another object of the invention is to provide an apparatus of the class described that can be specially tailored to accommodate directional fluid flow as, for example, downhill fluid flow.
- Another object of the invention is to provide an apparatus of the described in the preceding paragraph which, because of its unique design, cannot jam and will automatically open to permit fluid flow through the flow control channel when the flowing water impinges upon control vanes.
- Another object of the invention is to provide an apparatus as described in the preceding paragraphs that is easy to install and in no way affects the structural integrity of the storm drain.
- Another object of the invention is to provide an apparatus of the class described in which the flow control vanes of the apparatus can be readily modified for use in storm drains of varying height and width.
- Another object of the invention is to provide an apparatus of the class described in the preceding paragraph which, because of the unique design of the lightweight flow control vanes of the apparatus, permits a significantly higher flow volume of water through the fluid flow channel than is permitted by prior art devices embodying perforated flow control gates.
- Another object of the invention is to provide an apparatus as described in the preceding paragraphs that is easily adjustable to accommodate varying fluid flow conditions.
- Another object of the invention is to provide an apparatus of the class described that is durable in use and one that can be inexpensively manufactured, installed and maintained.

FIGS. 1 and 2 , one form of the fluid flow control, analysis and debris intercepting apparatus of the invention is there shown as it appears when positioned within a storm drain opening. This embodiment of the apparatus, which is generally designated in the drawings by the numeral 12, functions to control the flow of fluid and the introduction of debris into the opening “O” of the storm drain “SD” that comprises a structure “S” having spaced apart side walls “W” that define the opening “O” through which fluid, such as rainwater flows. As will be discussed in greater detail in the paragraphs that follow, this embodiment of the invention also uniquely includes a plurality ofsample collection assemblies 14 that are connected to uniquely configuredflow control vanes 16, the construction and function of which will be described in greater detail in the paragraphs which follow. As best seen inFIGS. 5 and 6 of the drawings, each of the collection assemblies comprises acollection container 18 and asample collecting media 20. Collectingmedia 20 can be made up of a wide variety of materials, but preferably comprises a material selected from the group consisting of activated carbon, polypropylene and absorbent cellulose. - In the form of the invention shown in
FIGS. 1 through 4 , theapparatus 12 comprises asupport member 22 to which theflow control vanes 16 are pivotally connected.Support member 22, which comprises an elongated, generally cylindrically shaped pivot rod having first andsecond extremities FIG. 4 ), is connected to side mountingmembers 24, which are in turn connected to structure “S” in the manner shown inFIG. 1 of the drawings. -
Flow control vanes 16 uniquely function to control fluid flow through the fluid flow channel and to selectively block the entrance of debris into the channel. As illustrated inFIGS. 7 and 8 of the drawings, each of theflow control vanes 16 has afront face 16 a, arear face 16 b, anupper portion 16 c, anintermediate portion 16 d and alower extremity 16 e. Theupper portion 16 c of each of the flow control vanes is provided with atransverse bore 26 that is constructed and arranged to slidably receive thesupport member 22. The front face of each of the flow control vanes is provided with a generallyU-shaped groove 28 that is adapted to slidably receive aguide member 30 having atransverse bore 30 a (FIG. 7 ).Groove 28 is also adapted to slidably receive the mountingcolumn portion 18 a of each of thecollection containers 18 of thecollection assemblies 14. - Also forming an important aspect of the present invention is an elongated, biasing member, shown here as an elongated, yieldably deformable biasing cable 40 (
FIGS. 2 and 4 ) having afirst end 40 a and asecond end 40 b.Cable 40 is received withinopenings 30 a formed in the guide members 30 (seeFIG. 7 ).Cable 40 uniquely functions to controllably resist movement of the vanes toward their second position. In a manner presently to be described,cable 40 is continuously maintained in tension and the degree of tension in the cable is regulated by anovel tensioning mechanism 42 that is carried by the structure “S”. As best seen inFIGS. 9 and 10 , this important tensioning mechanism here comprises ahollow housing 44, acable retaining cup 46 disposed withinhousing 44 for rotation with respect thereto and a finger engagingratchet wheel 48 connected to the housing for rotation with respect thereto. As illustrated inFIG. 11 of the drawings, finger engagingratchet wheel 48 has aperipheral portion 48 a provided with a multiplicity of circumferentially spaced apartteeth 48 b and acentral stem 48 c that extends outwardly therefrom.Stem 48 c extends through thecentral opening 50 a of aconventional torsion spring 50 that is mounted withincable retaining cup 46.Torsion spring 50 has afirst end 50 b that is connected to thecable retaining cup 46 and asecond end 50 c that is connected to finger engagingratchet wheel 48. - After the
tensioning mechanism 42 has been connected to theside mounting panels 24 in the manner shown inFIG. 10 , the end of the biasingcable 40 can be fed through the receivingslot 54 formed in thehousing 44 in the manner shown inFIGS. 10 and 11 . This done, the end of the biasing cable can be fed through the receivingslot 46 a formed in thecable retaining cup 46 and suitably interconnected with the cable retaining cup. With this construction, tension can be applied to the biasingcable 40 by grasping thefinger engaging bar 48 d of the ratcheting wheel and rotating theratcheting wheel 48 against the urging oftorsion spring 50. To release tension on the biasingcable 40, aratchet release pawl 56 is pivotally connected tohousing 44 in the manner illustrated inFIG. 11 of the drawings. The ratchet release pawl is movable between a first position wherein the teeth 56 a on the pawl engage theteeth 48 b preventing rotation of said finger engaging ratchet wheel and a second position permitting rotation of said finger engaging ratchet wheel. Aconventional coil spring 58 functions to releasably maintain the release pawl in its first position. - In using the apparatus of the invention, the
cable 40 is first tensioned in the appropriate manner by rotating thefinger engaging knob 48 of the tensioning mechanism, which is operably associated withspring 50. As the water flows through the fluid flow channel and impinges on thecontrol vanes 16, the control vanes will tend to move in the manner shown inFIGS. 3 and 4 of the drawings. However, since the control vanes are interconnected with thecable 40, the cable will yieldably resist the movement of the control vanes. It is apparent that the degree of tension placed on thecable 40 controls the amount of force that must be imparted on the control vanes by the flowing fluid to move the cable into the configuration shown inFIG. 4 . The greater the tension on thecable 40, the greater is the force against the fluid flowing through the storm drain “SD” and impinging on the control vanes that is required to move the cable into an arcuate configuration as is illustrated inFIG. 4 and to move the control gate into an open position. Conversely, the lesser the tension on thecable 40, the lower is the force against fluid flowing through the storm drain “SD” and impinging on the control vanes that is required to move the control gate into an open position. With this in mind, during periods of heavy rainfall when it is desired to encourage maximum fluid flow through the storm drain, a lesser tension is placed on thecable 40 so that the control gate can open widely to permit maximum fluid flow and also to permit debris, such as plastic bottles and the like that may build up against the control gate to flow freely into the storm drain. However, during periods of light rainfall when it is desired to accommodate the light rainfall, but at the same time to prevent debris from entering the storm drain, a greater tension is placed on thecable 40 so as to prevent the control gate from opening wide enough to permit the debris to move past the control gate and enter into the storm drain. - Turning now to
FIGS. 5 through 8 of the drawings, it can be seen that thecollection container 18 of each of the collection assemblies of the invention comprises interconnected front andside walls side walls top wall 66. Connected totop wall 66 and extending upwardly there from is the previously mentioned mountingcolumn 18 a that is generally T-shaped in cross-section. Thesample collecting media 20, which is disposed within the collection container, is held in position by arear wall 70 that includes vertically spaced apart slats 72. Connected to therear wall 70 and extending outwardly there from is thetop wall 66 that is provided with a generally T-shapedopening 66 a through which mountingcolumn 18 a is slidably received in the manner shown inFIG. 6 . It is to be observed that the spaced apart slats 64 and 72 provided on the walls of the collection container define a plurality of fluid ports that permit fluid flow into the connecting container in a manner to uniformly wet the collectingmedia 20 that is disposed within the container. - As previously mentioned and as illustrated in
FIGS. 7 and 8 of the drawings, in operation the mountingcolumn portion 18 a of each of thecollection assemblies 14 is slidably received within the generallyU-shaped groove 28 formed in the front face of each of the flow control vanes 16. With this construction, the collection containers and thesample collecting media 20 disposed there within is strategically positioned in the path of the wastewater flowing through the fluid flow channel. - Turning next to
FIG. 9 of the drawings, an alternate form of collection assembly and sample collecting media of the invention is there shown. This form of the collection assembly and sample collecting media, which is designated by the numeral 77, is similar in construction and operation to the embodiment shown inFIGS. 5 through 8 . However, as indicated inFIG. 9 , it is of a greater length so that it can be more effectively used in flow channels of greater depth. - Referring now to
FIG. 12 of the drawings, still another form of the fluid flow control and debris intercepting apparatus of the invention is there shown as it appears when positioned within a conventional curbside storm drain. This form of the apparatus, which is generally designated in the drawings by the numeral 80, functions to control the introduction of fluid and debris into the entrance of a conventional storm drain.Apparatus 80 is similar in many respects to the embodiment of the invention shown inFIGS. 1 through 8 and like numerals are used inFIG. 12 to identify like components. The primary difference between this latest form of the invention and that of the previously described invention resides in the provision of tensioning mechanisms that are of a different construction and operation from thetensioning mechanisms 42 of the embodiment of the invention shown inFIGS. 1 through 8 . - As before, the apparatus includes a plurality of
sample collection assemblies 14 that are connected to uniquely configuredflow control vanes 16, which are, in turn, pivotally connected to asupport member 22.Support member 22 is connected to side mountingmembers 24, which are connected to structure “S” in the manner shown inFIG. 1 of the drawings. As in the earlier described embodiment of the invention, the front face of each of the flow control vanes is provided with a generallyU-shaped groove 28 that is adapted to slidably receive aguide member 30 having atransverse bore 30 a (FIG. 7 ).Groove 28 is also adapted to slidably receive the mountingcolumn portion 18 a of each of thecollection containers 18 of the collection assemblies 14 (FIG. 5 ). An elongated, yieldablydeformable biasing cable 40 having first and second ends 40 a and 40 b is received withinopenings 30 a formed in the guide members 30 (seeFIG. 7 ). -
Cable 40 functions to controllably resist movement of the vanes toward their second position and is continuously maintained in tension byswivel connector assemblies 82 that are mounted onside mounting members 24. As illustrated inFIG. 12 , the ends 40 a and 40 b ofcable 40 are securely connected toconnector assemblies 82 by a suitable means. More particularly, the cable end portions are connected to anangle bracket 84 that is rotatably connected to theside mounting members 24 by a threadedconnector 86. With this construction, as the water flowing through the storm drain moves the vanes out of their vertical plane and into their second, displaced configuration as illustrated inFIG. 4 , theangle brackets 84 will rotate relative to theside mounting members 24 and in so doing will function to effectively regulate the tension on thecable 40. - Turning next to
FIGS. 13 and 14 of the drawings, yet another form of the fluid flow control and debris intercepting apparatus of the invention is there shown. This form of the apparatus, which is generally designated in the drawings by the numeral 90, is similar in many respects to the embodiments of the invention shown inFIGS. 1 through 8 and 12 and like numerals are used inFIGS. 13 and 14 to identify like components. The primary differences between this latest form of the invention and that of the previously described invention resides in the absence of the sample collection assemblies and the provision of a totally different biasing mechanism for controlling movement of the vanes toward their second position. - In this latest form of the invention, the apparatus comprises a plurality of uniquely configured
flow control vanes 16, which are pivotally connected to asupport member 22.Support member 22 is connected to side mountingmembers 24, which are in turn connected to structure “S” in the manner shown inFIG. 1 of the drawings. As in the earlier described embodiments of the invention, the front face of each of the flow control vanes is provided with a generallyU-shaped groove 28 that is here adapted to slidably receive aguide member 92 having atransverse bore 92 a. - Forming an important aspect of this latest form of the invention is the previously mentioned tensioning member, here provided as an elongate
tension spring member 94 having first and second end portions that are secured to side mountingmembers 24 by means of novelswivel connector assemblies 96.Tension spring members 94 are readily commercially available from various sources including the Jones spring Co. Inc. of Wilder Ky. These spring members, which can be provided in various diameters ranging from ⅛ to ⅜ inches in diameter, have proven to be suitable for the purposes of the present invention. - As best seen in
FIG. 14 of the drawings, each of theswivel connector assemblies 96, which connect the spring members to theside mounting members 24, include anangle bracket 98 thefirst leg 98 a of which is rotatably connected to the mountingmember 24 by a threadedconnector 86 and thesecond leg 98 b of which extends perpendicularly outward from the mounting member (FIG. 14 ). The ends of thetension spring member 94 are removably connected to thesecond leg 98 b of the angle bracket by any suitable means such as elongate threadedstuds 100 andmating connector nuts FIG. 14 of the drawings, threadedstuds 100 have a first end connected to the tension spring member and a second end connected to the angle brackets by means of theconnector nuts first legs 98 a of the angle brackets rotate relative to theside mounting members 24 due to the movement of the control vanes out of plane and toward their second positions as a result of liquid flowing through the flow channel (seeFIG. 4 ). - The selection of a suitable
tension spring member 94 for use in a particular storm drain configuration is accomplished in accordance with the method of the invention described in the paragraphs which follow. - Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention as set forth in the following claims.
