BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for the release of a fish hook which is connected to its snood through a head of the type which in a transversely-extending opening receives a substantially U-shaped lead spring which is movable in the opening in the longitudinal direction of the head and the branches of which are adapted to cooperate with an annular face on the leg of a fish hook and, in part, to be spread when each cooperates with an oblique surface in the opening for the purpose of releasing the engagement between the hook leg and the leaf spring. For the movement of the leaf spring in the longitudinal direction of the head for the purpose of spreading the leaf spring branches so that the fish hook leg be released from engagement with the leaf spring branches, the part of the spring which interconnects the two branches is provided with projections which may be activated from the outside.
The object of the invention is to provide an apparatus which in a simple and secure manner may be caused to perform the noted external activation of the leaf spring relative to the head proper.
SUMMARY OF THE INVENTION
According to the invention, the apparatus comprises a housing having a longitudinal cavity with a cross section which corresponds to the cross section of a snood head and having a conical entry portion wherein a number of radial and oblique wire springs are arranged, the ends of the wire springs extending into the cavity, as well as a cock which may extend into the cavity, is pivotably mounted in the housing and is provided with a caster adapted to cooperate with a stationary cam during movements of the housing in the longitudinal direction of the cavity. In such an apparatus the movement of the leaf spring relatively to the associated oblique faces required for the release of the hook leg, be obtained by displacement of the snood head relatively to the apparatus housing under the control of the engagement between the caster and the cam. Further features of the apparatus according to the invention will appear from the following description, with reference to the accompanying drawings.
DESCRIPTION OF THE DRAWINGS
FIGS. 1a, 1b and 1c show side views of a snood head adapted for treatment in an apparatus according to the invention, FIGS. 1a and 1b being views of the head as seen in mutually perpendicular directions with a hook leg in locked position, and FIG. 1c being a view similar to that of FIG. 1a with the leaf spring in position for release of the hook leg.
FIG. 2 is an end view of the apparatus according to the invention, as seen in the direction of the axis of the longitudinal cavity.
FIG. 3 is a side view as seen at right angles to the longitudinal cavity.
FIG. 4 is a side view, at a larger scale than those of FIGS. 2 and 3 of the apparatus, partly in section through the longitudinal cavity.
FIG. 5 is a side view corresponding to that of FIG. 3, at a later time during the release of the hook.
FIG. 6 is a view, partly in section, corresponding to that of FIG. 5, but on a larger scale.
FIG. 7 is a side view, corresponding to those of FIGS. 3 and 5, after the release of the fish hook.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A snood head which is particularly suited for treatment in an apparatus according to the invention is illustrated in FIGS. 1a, 1b and 1c. It consists in an elongated member 1 which is preferably made of plastic material and was a circular or rectangular cross section. At one end the elongated member is provided with an eye 2 adapted to receive and secure a snood and at its other end it is provided with a longitudinal cavity 3 which is adapted for introduction, receiving and removal of the leg 4 of a fish hook. Along the length of the cavity 3 it is extended to a transverse opening 5 which at the end facing the introduction end of the cavity 3 presents a plane surface 6 and in the opposite direction presents two oblique surfaces 7. Each of the surfaces 7 is in the transverse direction split in two, such that the cavity 3 is ext
