referring to the drawings , there is shown in fig1 to 3 a first embodiment of the present invention . in this first embodiment , a lure for catching squid and the like includes a hollow elastic body 1 which is provided with a hook indicated generally at 2 . the hook 2 has a core 2a and the upper part of the core 2a forms a shank 2b which passes into the interior of the elastic body 1 through a hole 3 in the lower end of the elastic body 1 . the shank 2b is integral with and is a part of the core 2a . the elastic body 1 also has another hole 4 at its other longitudinal end for introducing a fishing line 5 into the elastic body 1 . the elastic body 1 may be made of resilient material such as plastic , rubber or the like and may be colored , for example red , or yellow , or it may be coated with silver dust or luminous paint . the core 2a is bent at its lower end and is arranged to receive a connecting ring 8 which is in turn connected to a fishing line 5a . the shank 2b also has a bent end 7 which is connected to the fishing line 5 . umbrella hooks 2c encircle the core 2a and are secured thereto by rings 2d to prevent their sliding on the core 2a . as can best be seen in fig2 the fishing line 5 is connected to the end loop 7 of the shank 2b of the hook and passes out of the elastic body 1 through the hole 4 . it will be seen that by pulling of the fishing line 5 , the hook 2 will be drawn into position as shown in fig2 wherein the shank 2b passes through the hole 3 of the elastic body to be releasably held in the position shown in fig2 . apertures 6 may be provided in the elastic body 1 to permit air or water to pass between the inside and outside of the elastic body 1 while providing bubbles . as shown in fig6 a suitable number of lures of the type shown in fig1 and 2 may be attached to a fishing line 5 in series arrangement and the line caused to descend in a body of water by the provision of a single weighted sinker 11 which may be made of lead . if the fishing line is pulled up when a squid embraces or otherwise contacts the hollow elastic body 1 , the latter tends to be compressed longitudinally towards the hook 2 . the pressure applied to the lower end of the elastic body 1 by the hook 2 and the resistance of the water against the passage of the elastic body 1 therethrough as the fishing line 5 is pulled up will cause the elastic body to collapse longitudinally and thereby force the squid more deeply onto the hook 2 . expressed otherwise , when a squid is adjacent the hook 2 and the line is pulled up , the elastic body 1 will tend to collapse towards the hook 2 thereby tending to push the squid deeper onto the hooks 2 . thus , the squid will be embraced between the collapsing elastic body 1 and the hook 2 so that the hook 2 will bite more deeply into the squid as the fishing line 5 is pulled up . because of the squid &# 39 ; s weight , there will be a great resistance caused by the squid when the line is pulled up . for example , when pulling in the line in water of 150 meters deep , a resistance power of 1 to 3 kg works on the hollow elastic body . from the above description , it will be seen that the lure according to the present invention operates to effectively catch and hook the squid when the fishing line is pulled up . in addition , it is possible to attach a large number of lures to a single fishing line and arrange these lures in series as shown in fig6 . thus none of the individual lures need require any weight or lead or the like . moreover , these light , hollow elastic bodies can sway somewhat in the sea and as the water passes inside and out of the hollow elastic bodies through the holes 6 , small bubbles may rise through these apertures 6 which will tend to attract the attention of the squid . at the same time , the elasticity of the body 1 tends to prevent the squid from becoming unhooked as the line is pulled up . it will be further seen , that due to the elastic nature of the body 1 , the hook 2 may be displaced out of longitudinal alignment as shown by broken lines in fig2 and 5 thereby affording flexibility in its operation . also bait may be placed in the elastic hollow body . fig4 shows a second embodiment of the present invention wherein like numerals are used for like parts . in the embodiment of fig4 there is provided an elongated shank 7a on the hook 2 . the elongated shank 7a extends the entire length of the elastic body 1 and passes out through the hole 4 in the upper end of the elastic body 1 . the external portion of the shank 7a is connected to a connecting ring 9 which is in turn connected to the fishing line 5 . the advantage of this arrangement is that there is avoided the necessity of having to thread the fishing line through the elastic body 1 of the lure . in other words , since the shank 7a passes externally of the elastic body 1 , the fishing line 5 may be easily connected to the external part of the shank 7a . in the embodiment of fig5 the shank 7b of the hook 2 terminates within the elastic body 1 as in the embodiment of fig1 and 2 but in fig5 the shank 7b of the hook 2 is connected to linking element 10 which passes through the hole 4 of the elastic body 1 to a position external of the body . the external part of the linking element 10 is connected to a connecting ring 9 which is in turn connected to the fishing line 5 . the arrangement in fig5 as in the case of the embodiment of fig4 also avoids the necessity of having to thread the line through the elastic body 1 of the lure . another advantage of the fig5 embodiment is that it is possible to wind up a plurality of such lures on a reel with minimum projecting parts inasmuch as there is a flexible joint between the shank of the hook and the linking element 10 and the lure can bend at this joint as the latter is wound up around a cylindrical body such as a reel . as can be seen in the embodiments of fig4 and 5 , a plurality of apertures 6 may be provided throughout the elastic body . fig3 shows the elastic body partially collapsed . it is thought that the invention and its attendant advantages will be understood from the foregoing description and that it will be apparent that various changes may be made in the form , construction , and arrangements of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages . the forms heretofore described being merely preferred embodiments thereof .
