Description: Description Device for big fish baiting Field of the invention The present invention relates to a device for fish baiting intended for amateurish fishing of big fishes, such as tuna, shark, etc. Background art In the prior art, amateurish fishing of big fishes uses: - either a cage fixed by means of a cable to a craft and containing some little fishes, such as cephalopods or sardines, as baits for big ones, - or little fishes which are thrown by hand from the craft, so as to create, while the craft advances, an appeal wake for big fishes. The big fishes which are so baited in the proximity of the craft, are then caught by means of a fishing rod carrying its own bait fixed to its hook. Disclosure of the invention The present invention seeks to provide an improvement for such an amateurish fishing. According to an aspect of the present invention there is provided a device for big fish baiting as specified in claim 1. An advantage which may be obtainable with the present invention is the creation of an appeal wake for big fishes which, while being effective, avoids manipulation of the baits. Best mode for carrying out the invention A prefered embodiment of the present invention is described below, by way of example only, with reference to the following figures: - FigJ is a perspective view of a preferred embodiment of the invention; - Fig.2 is a sectional view of the embodiment shown in FigJ , according to the longitudinal axis of the oblong container shown therein; - Fig.3 is a developped view of the conveyor band shown in FigJ and Fig.2 and equipped with gripping means; - Fig.4 a and b are respectively a front and a side view showing in detail the gripping means of the conveyor band shown in FigJ to Fig.3 - Fig.5 and Fig.6 are respectively a back and a front view of the embodiment shown in FigJ ; - Fig.7 shows one of two identical side wings by means of which the driving means are connected to the container; - Fig.8 shows the embodiment of FigJ equipped with a protection casing made from a transparent plastic material. FigJ and Fig.2 show an oblong container 1 sloped with respect to fastening means 2 consisting of an approximately V- shaped stirrup which, while supporting the container, allows fixation thereof, by means of a screw-nut tightening 3, to a craft (not shown) sailing the sea, or generally a water environment (not shown). The container 1 , which resembles a mini-toboggan, has an upstream end closed with a wall 4 and a downstream opened end 5 as well as longitudinal walls 6 and 7 connecting these upstream and downstream ends. When the container 1 is filled with baits 8, such as cephalopods or sardines (see Fig.2), these latter slide, under the effect of gravity, along the bottom 9 towards the downstream opened end 5, thus feeding means - which will be disclosed in detail hereinafter - intended to convey them towards the sea, so as to create therein an appeal wake for big fishes, such as tuna or shark. While reducing into practice the present invention it has been apparent that the most effective manner to convey the baits without wasting is to have conveying means able to remove the baits one by one from the feeding container 1 by means of appropriate gripping means fixed to the conveying band 10. To that effect, the downstream opened end 5 of the container 1 is closed by an upwardly oriented conveying band 10 envelopping two rolls 11 and 12. The roll 11 is driven by an electric motor 13, supplied by the battery of the craft: see also Fig.5 and Fig.6 where are shown the motor shaft 14 and the axis 15 of the driven roll 11. In order to convey the baits 8 one by one from the feeding container 1, the coveying band 10 is provided with gripping means consisting of hook needles 16 fixed thereon and uniformly spaced longitudinally as well as transversally. FigJ shows four hook needles fixed on the band, whereas Fig.6 shows five of such hook needles. Fig.3 shows five hook needles 16 on the developped band 10 and it is possible to appreciate the regular longitudinal and transversal spacing between the hook needles: these spacings while being generally different there between are equal in the same direction. It is also possible to appreciate that this regular double spacing concerns the extreme hook needles too when the transversal edges of the band 10 are joined end by end. In Fig.4 it is shown the preferred shape of the hook needles 16, supported by a nylon base 17 for fixation to the band 10. The band 10 is mounted on the rolls 11 and 12, so as to have the hook needles 16 upwardly oriented on the feeding means side and downwardly oriented on the water environment side (see Fig.2). Of course, the edge of the downstream opened end of the bottom container has a number of notches 18 equal to the number of hook needles 16, allowing these latter to pass therethrough when the conveying band 10 is driven by the driving means. Such notches 18 allow also liquids (sea water or liquids produced by the very same baits) to flow therethrough. From Fig. 5, Fig.6 and Fig.7 it is clear for a person skilled in the art how to mount the different components of the device provided by the present invention. Anyway, hereinafter it is briefly disclosed how to carry out the assembly. The rolls 11 and 12 are supported by two lateral identical wings 19. Fig.7 shows the holes arranged on each wing so as to render effective the assembly. The holes 20 at the periphery of the wings allow the fixation to the longitudinal walls 6 and 7 of the container 1. The holes 21 allow the assembly of the two spacing axis 22 and 23 shown by dotted lines in Fig.6. The holes 24 allow the assembly of support means 25 and 26 (see Fig.6) consisting of a muff and a bolt respectively aiming at stabilizing the assembly of the box 27 containing the motor 13 and the circuitry. Even if a unique hole of the type 24 is sufficient, both wings 19 are provided with such a hole so as to allow the assembly of the box 27 on the left or right side of the container, according to the mounting possibilities on the craft. The hole 28 allow the assembly of the axis 15 of the roll 11 intended to be driven by the motor shaft 14. The holes 29 allow the assembly of the axis of the roll 12. These holes are oblong so as to have the possibility to regulate the tension of the band 10. To that effect a spring 31 is mounted on a bolt 32 perpendicular to each end of the axis of the roll 12, this spring being intended to be compressed between each one of these latter ends and a ring 33 fixed to each wing 19 through the holes 30: it is clear that the right adjustment of the band tension is obtained by sliding the bolts 32 in the rings 33, due to the oblong character of the holes 29, and then by tightening in the appropriate position the axis of the roll 12. Preferably, the container is made from vitro-resin, resistant to sea water and easily washable, but it could be made from stainless steel. The band 10 is made of plastic material. Hereinafter there is disclosed the operation of the device provided by the present invention. The motor 13 takes off roll 11 into rotation. Together with the roll 12, the roll 11 takes off the conveying band 10 provided with the hook needles 16, which, by passing upwardly through the notches 18 of the container bottom 9, hook one after the other, among the baits 8 feeded by the feeding means 1 , that bait which is intercepted by one of the hook needles. After reaching the top of the conveying band 10 each bait 8 follows a downward path, so that under the effect of its own weight it leaves the corresponding hook needle falling into the water. At the beginning of the downward path, each bait 8 intercepts the beam 34 emitted by an infrared - ray photo - switch 35. When the nature of the baits 8 (such as sardines) allows the reflection of the beam 34 thereon, this reflection switches the motor 13 off, thus stopping the conveying band 10. This kind of operation corresponds to Fig. 1 and 6. When the nature or status of baits 8 (such as cephalopods or sardines with a few or without scales) is improper for beam reflection, the operation of the switch 35 is based on the reflection of the beam on a catadioptrical reflector 36 (see Fig. 8), in the sense that the absence of a reflected beam, corresponding to the interception of a bait 8, switches the motor 13 off. This kind of operation is illustrated in Fig.8. In each case, after interception of the switch beam by a bait, a timer (not shown, intended to be put inside the box 27 containing the motor 13 and circuitry) allows to regulate the time interval after which the motor 13 can operate again , so as to initiate a new cycle for ejecting a new bait. The time interval (in seconds) of the timer can be preselected by means of a potentiometer 37 (see Fig. 6). This time interval is chosen in function of the sailing speed as well as the speed of the sea current. Sometimes, especially at the beginning of the creation of an appeal wake, it is desirable to create an appeal wake having a greater linear density of baits in the water (for linear density it is meant the number of baits for unit length of the appeal wake. In this case, it is appropiate to put the switch 35 in the off position, so as to let the driving means 13 run continuously during a given time, thus raising the baiting probability. A further increasing of the baiting probability can be obtained by means of a triturator 38 supplied by means of an inlet (see Fig. 1 ,2, 5 and 8). It is fixed to the box 27 by means of a dovetail joint 39 allowing the transversal sliding of the triturator in order to intercept at least one trajectory (at the most two trajectories) of the baits 8 taken off downwardly by a corresponding hook needle 16. In such a manner, it is possible to create in the water a supplemental appeal wake due to continuous diffusion of a smell spread along said appeal wake by the triturated baits. Of course, it is useful to construct the triturator from stainless steel. In order to protect the user from damage due to the presence of the hook needles on the conveying band, it is useful to provide the device shown in FigJ with a protection casing 40. This latter is illustrated in Fig. 8, which differs from Fig.1 essentially to show the possibility of using five hook needles 16 (instead of the four ones shown in FigJ) and of using a catadioptrical reflector 36. It can be appreciated from Fig. 8 that the protection casing 40 is made from a transparent material, such as plexiglass, so as to let the switch 35 operate while allowing visual control of the device operation. The transparent protection casing 40 comprises a top portion 41 envelopping the top portion of the conveying band 10, a low portion 42 protecting from the inferior part of the band and a bottom portion 43 orienting the baits falling towards the water. Of course, the top portion is opened downwardly, as shown by arrow 44, to let the falling of the baits partly in the triturator 38 and partly in the water. The transversal wall 45 connecting the lateral walls of the protection casing 40 is provided with notches 46 corresponding to the notches 18 arranged on the edge of the container bottom. Furthermore, the slope of the feeding container 1 can be adjusted by arranging for example at the top of the two branches 2a and 2b of the fastening means 2(see Fig. 1 ,2 and 5) several holes 2c (see Fig. 2) : by choosing one pair of such opposing holes 2c, before tightening the branches 2a and 2b to the side walls 6 and 7 of the feeding container, it is possible to adjust the slope thereof.
