McKeen, Torrance, Calif. , Application April 27, 1945, Serial No. 590,532 ‘10 Claims. (Cl. 43-80) 1 . More specifically speaking the invention per Y 2 A ` being considerably less than the internal diameter tains to a type of rodent trap wherein spring of the barrel ‘I so as to provide an annular space actuated means causes one or more pointed mem bers to penetrate the body of the animal, the de vice being actuated by a trigger which the ani Y I2 slidable within the barrel and fixed to the hook-carrying rod I3, the diameter of saidfhead » This invention relates to a rodent trap. Ul mal releases when it emerges from a hole or burrow in the ground. >It is an object of the invention to provide an improved combined body-gripping and body piercing or impaling means, so that when the trap is released the body of the animal willbe both pierced and gripped thus making it doubly sure that it Will not escape from the trap. Another object relates to the provision of an improved relative positioning of the trigger of the trap in relation to the body-gripping and body piercing members so that, when the animal re leases the trigger, its body will at such time be positioned directly in the path of the spring actuated body-gripping and body-piercing means. to receive loosely the adjacent endportion of the operating spring I 4, of the spiral, compression type. The end portion of _rod I3 opposite to its head I2 carries a multiple hook structure I5,` three pointed hooks I6 being shown spaced 120 Ydegrees apart. One end of spring I4 bears against shank II and lthe opposite end of said‘spring bears against the annular shoulder resulting from in ternally thickening the wall of the barrel as indi» catedat I'I. , I ` ,I Y ‘_ ‘Y A -rodent-releasable p catchA vmeans >is provided which includes a trigger member 20‘to releasably maintain the rod I3 in its extended, set position against the opposition of the spring IAI, said trig«_ger member cooperating with a catch or shoulder 2| drop-forged or otherwise formed upon the rod. As best shown in Fig. 3 said trigger member c0111, A further object is to provide a more efficient trap for catching the gopher as it emerges from its burrow, this animal being a serious menace prises a Wire 22 so bent that three `runs thereof to agriculture in many sections of the United ‘ a terminal portion 24 which is bent back in such a Way as to cooperate with‘the adjacent side‘por tion ofthe barrel to act as a stop Íto llimit the swing of the trigger member when'it moves to set States. Other objects, advantages and features of in vention will hereinafter appear. Referring to the accompanying drawing which illustrates what at present is deemed to be a preferred embodiment of the‘invention, Fig. 1 is a side elevation of the trap showing it in the set condition. . outline both ends and one side of an elongated rectangle, one of said runs 23 of said Wire having position. The already , mentioned` Wire . run` 23 ¿ _passes transversely and turnably through the adjacent end portion of the barrel and is provided with a catch shoulder` 25 to cooperatey with the catch lug 2l carried -by 4rod I3. The opposite end por tion of the trigger member` 20 is shown carrying Fig. 2 is a longitudinal mid-section showing the trap in the set position and including in the view an apron 2'I which insures that the rodent> will the mouth portion of a gopher’s burrow together release said trigger either by moving dirt or his with the recess in the soil which the operator will body against said' apron.
