FISH PUMP NOZZLE WITH I~AFFLE
BACKGROUND OP THE INVENTION
S Field of the Invention This invention relates to nozzles used for pumping liquids containing relatively large solid objects such as fish.
Description of Related Art The handling of fish, and in particular the unloading of fishing boats, was considerably expedited with the development of the fish pump which allows the fish to be pumped from the hold of a fishing boat directly to a shore installation such as 15 a processing plant. Such fish pumps have typically used tapered nozzles in order to feed the fish into the flexible conduit as seen, for example, in United States Patent No. 2,722,461 to Tholl. However, problems have often been encountered with such nozzles because they are prone to be jammed by fish which enter the nozzle perpendicular to the direction of flow. Attempts have been made to provide more 20 efflcient guides for me intake of fish such as seen in United States Patent No.
3,940,867 to Sikich. This guide is adapted for pumping from nets rather than tanks.
However, problems with efficient feeding of fish or similar objects from tanks into pumps have persisted, thus leaving a need for an improved nozzle for fish pumps as 25 well as pumps for other such relatively large objects pumped in a liquid medium.
SUMMARY OF THE INVENTION
It is an objection of the invention to provide an improved nozzle for pumping 30 relatively large objects such as fish, which feeds the objects efficiently into a conduit without jamming.
It is another object of the invention to provide an improved intake nozzle for " , . .

pumping fish or other objects from a holding tank which can be positioned on thebottom of the tank without blocking the flow of fish or other such objects into the nozzle.
5 It is a further object of the invention to provide an improved nozzle for pumping fish and other such objects which is rugged in construction, economical to produce and reliable in operation.
In accordance with these objects, one aspect of the invention provides an intake10 nozzle for a pump, comprising a conical shell having an inside, a narrow end with means for connecting a conduit to the nozzle and a wide end having an opening for receiving fish or other objects. There is an interior space having a longitudinal baffle ~ ~
extending between the ends. -15 Another aspect of the invention provides a fish pump nozzle with a conical shell having an inside, a narrow end with means for connecting a conduit to the nozzle, a wide end having a fish receiving opening and a side wall extending between theends and having a first side and a second side.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring first to Fig. 1, an intake nozzle according to the invention is shown generally at 10 connected to a flexible conduit 12 which in turn is connected to a fish 15 pump 14. A conventional ribbed PVC hose is used for conduit 12 in this example, though other conduits could be substituted. The fish pump and conduit are well known in the prior art and therefore are not described in more detail. It should be understood however that the pump could be used for pumping other products besides fish. A coupling 16 serves as means for connecting the conduit 12 to the20 nozzle. This is a standard compression flange coupling including two flanges with an O-ring there between. Other couplings could be used instead.
The nozzle 10 has a conical sheil 18 which is made of stainless steel in this example.
This material is preferred for use in salt walter. Other materials could be 25 substituted, particularly if the nozzle is to be used in fresh water or non-corrosive liquids. The shell has a narrow end 20 equipped with the coupling 16. The opposite end 22 is 6ubstantially wider than the narrow end. The shell tapers inwardly from the wide end 22 ~towards the narrow end 20. The wide end 22 provides an opening 24 for admitting fish or other materials into the nozzle.
The nozzle has an interior space 26 within the shell. A baf~e 28 is located within the interior space. In this particular embodiment the baf~e is generally triangular '' ~ ' ' - ,' '.
209822~
having a first side 30, second side 32 and a third side 34. The shell 18 has an interior side wall 36, a first side 38 and a second side 40 as seen in Fig. 2. The baffle 28 has its first side 30 connected along first side 38 of the shell. The baffle extends inwardly part way across me inside of the shell towards second side 40. The second side 32 of the baffle extends from first side 38 of the shell adjacent its wide end 22 towards second side 40 thereof. Side 32 makes an acute angle with the wide end æof the shell. The third side 34 of the baffle extends from the first side 38 of the shell towards the second side 32 of the baffle. There is a rounded corner 42 where thesecond and third sides of the baffle intersect.
As best seen in Fig. 3, the baffle is uniform in thickness from the position where it is connected to first side 38 of the shell 18 except for rounded edge 44 which extends along sides 32 and 34 as well as corner 42.
Thus, as best seen in Fig. 3, there is a passageway 46 defined between the baffle 28 and side wall 36 of shell 18 which allows fish or other objects to be taken up from wide end 22 of the nozzle towards narrow end 20 and into the conduit 12. It may be observed that the passageway is generally C-shaped in section.
Referring back to Fig. 1, it may be seen that the wide end 22 of the shell 18 isangled more acutely with respect to first side 38 of shell 18 than second side 40 thereof. Thus, when the nozzle is suspended from above by means of conduit 12, the wide end æ is inclined with respect to bottom 70 of fish holding tank 72. Thus there is an opening 74 for fish to enter the nozzle even when the nozzle contacts the bottom of the tanl~.
An alternative embodiment of the invention is shown in Fig. 4 and 5. The structure is generally similar to the previous embodilnent and like parts have like numbers with the addition of ".1". Because the structure is generally similar, the description will be restricted to the differences between the two embodiments.
Baffle 28.1 of nozzle 10.1 has generally teardrop-shaped member 49 as best seen in . , . . .
-` 2098229 Fig. 4. There is a rounded end 50 adjacent wide end 22.1 of shell 18.1 and a pointed end 52 adjacent narrow end 20.1. The baffle has a generally conical portion 54 extending between its ends. The baffle includes a fin-like member 55 connected along first side 38.1 of shell 26.1. The member 55 serves as a support for tear drop-5 shaped member 49. As seen in Fig. 5, member 49 extends centrally along the sideof the shell.
Anomer embodiment of the invention is shown in Fig. 6. Nozzle 10.2 is gcnerally similar to nozzle 10, but is adapted for emptying a fish pump holding tank 60. The fish pump holding tank has an intake 62. The nozzle 10.2 has its wide end 22.2 connected to outlet 64 of the tank. In this particular embodiment the baffle 28.2 of the nozzle has an extension 28.4 projecting into the tank 60. The tank is held at an angle which is inclined downwardly towards outlet 64 by means of supports 66 and68. Likewise the nozzle 10.2 is angled downwardly towards its narrow end 20.2.
In operation, with reference to Fig. 1-3, fish in the tank 72 are of course arranged in a random manner and thus enter the wide end of the nozzle without any particular alignment with respect to the direction of flow of water towards the fish pump 14. However, me baffle 28 causes the fish to be aligned eimer head first or20 tail first in tme direction of flow such mat the fish are parallel to the conduit 12 when they enter tme conduit. This ensures that the fish do not become jammed in the nozzle or conduit and that the flow rate of fish towards the pump is expedited. The alignment of the fish occurs gradually because of the decreasing size of passageway 46 as the nozzle tapers towards its narrow end 20. The velocity of fluid and fish in 25 the conduit 12 is, for example, approximately 15 times greater than at the wide end 22 of the nozzle in one example of the invention. Fish coming up against side 32 of the baffle from various angles are slowly brought around the baffle to align themselves head or tail flrst as they accelerate towards the conduit 12.
30 It will be understood by someone skilled in the art that many of the details provided above are by way of example only and can be varied or deleted without dcparting from tme scope of the invention which is to be interpreted with reference to the 209822~
following claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring first to Fig. 1, an intake nozzle according to the invention is shown generally at 10 connected to a flexible conduit 12 which in turn is connected to a fish 15 pump 14. A conventional ribbed PVC hose is used for conduit 12 in this example, though other conduits could be substituted. The fish pump and conduit are well known in the prior art and therefore are not described in more detail. It should be understood however that the pump could be used for pumping other products besides fish. A coupling 16 serves as means for connecting the conduit 12 to the20 nozzle. This is a standard compression flange coupling including two flanges with an O-ring there between. Other couplings could be used instead.
The nozzle 10 has a conical sheil 18 which is made of stainless steel in this example.
This material is preferred for use in salt walter. Other materials could be 25 substituted, particularly if the nozzle is to be used in fresh water or non-corrosive liquids. The shell has a narrow end 20 equipped with the coupling 16. The opposite end 22 is 6ubstantially wider than the narrow end. The shell tapers inwardly from the wide end 22 ~towards the narrow end 20. The wide end 22 provides an opening 24 for admitting fish or other materials into the nozzle.
The nozzle has an interior space 26 within the shell. A baf~e 28 is located within the interior space. In this particular embodiment the baf~e is generally triangular '' ~ ' ' - ,' '.

having a first side 30, second side 32 and a third side 34. The shell 18 has an interior side wall 36, a first side 38 and a second side 40 as seen in Fig. 2. The baffle 28 has its first side 30 connected along first side 38 of the shell. The baffle extends inwardly part way across me inside of the shell towards second side 40. The second side 32 of the baffle extends from first side 38 of the shell adjacent its wide end 22 towards second side 40 thereof. Side 32 makes an acute angle with the wide end æof the shell. The third side 34 of the baffle extends from the first side 38 of the shell towards the second side 32 of the baffle. There is a rounded corner 42 where thesecond and third sides of the baffle intersect.
As best seen in Fig. 3, the baffle is uniform in thickness from the position where it is connected to first side 38 of the shell 18 except for rounded edge 44 which extends along sides 32 and 34 as well as corner 42.
Thus, as best seen in Fig. 3, there is a passageway 46 defined between the baffle 28 and side wall 36 of shell 18 which allows fish or other objects to be taken up from wide end 22 of the nozzle towards narrow end 20 and into the conduit 12. It may be observed that the passageway is generally C-shaped in section.
Referring back to Fig. 1, it may be seen that the wide end 22 of the shell 18 isangled more acutely with respect to first side 38 of shell 18 than second side 40 thereof. Thus, when the nozzle is suspended from above by means of conduit 12, the wide end æ is inclined with respect to bottom 70 of fish holding tank 72. Thus there is an opening 74 for fish to enter the nozzle even when the nozzle contacts the bottom of the tanl~.
An alternative embodiment of the invention is shown in Fig. 4 and 5. The structure is generally similar to the previous embodilnent and like parts have like numbers with the addition of ".1". Because the structure is generally similar, the description will be restricted to the differences between the two embodiments.
Baffle 28.1 of nozzle 10.1 has generally teardrop-shaped member 49 as best seen in . , . . .
-` 2098229 Fig. 4. There is a rounded end 50 adjacent wide end 22.1 of shell 18.1 and a pointed end 52 adjacent narrow end 20.1. The baffle has a generally conical portion 54 extending between its ends. The baffle includes a fin-like member 55 connected along first side 38.1 of shell 26.1. The member 55 serves as a support for tear drop-5 shaped member 49. As seen in Fig. 5, member 49 extends centrally along the sideof the shell.
Anomer embodiment of the invention is shown in Fig. 6. Nozzle 10.2 is gcnerally similar to nozzle 10, but is adapted for emptying a fish pump holding tank 60. The fish pump holding tank has an intake 62. The nozzle 10.2 has its wide end 22.2 connected to outlet 64 of the tank. In this particular embodiment the baffle 28.2 of the nozzle has an extension 28.4 projecting into the tank 60. The tank is held at an angle which is inclined downwardly towards outlet 64 by means of supports 66 and68. Likewise the nozzle 10.2 is angled downwardly towards its narrow end 20.2.
In operation, with reference to Fig. 1-3, fish in the tank 72 are of course arranged in a random manner and thus enter the wide end of the nozzle without any particular alignment with respect to the direction of flow of water towards the fish pump 14. However, me baffle 28 causes the fish to be aligned eimer head first or20 tail first in tme direction of flow such mat the fish are parallel to the conduit 12 when they enter tme conduit. This ensures that the fish do not become jammed in the nozzle or conduit and that the flow rate of fish towards the pump is expedited.

The velocity of fluid and fish in 25 the conduit 12 is, for example, approximately 15 times greater than at the wide end 22 of the nozzle in one example of the invention. Fish coming up against side 32 of the baffle from various angles are slowly brought around the baffle to align themselves head or tail flrst as they accelerate towards the conduit 12.
