Abstract

This spinning reel has a winding drum rotated about a normally stationary spool to wind line thereon, and includes a pickup bail pivoted on the drum and spring biased form a casting position clear of the line to a winding position where it engages the line. When placed in the casting position a slidable plunger retains the pickup in casting position while ans associated spring biased, friction brake is applied to prevent accidental rotation of the winding drum. When it is desired to wind in the line, rotation of the winding drum causes a stop member to shift the plunger and thereby remove the friction brake application and permit the biased pickup to move to its winding position.

Description

*United States Patent FOREIGN PATENTS Primary Examiner-Billy S. Taylor A!t0rneys- Robert E. Burns and Emmanuel J. Lobato ABSTRACT: This spinning reel has a winding drum rotated about a normally stationary spool to wind line thereon, and includes a pickup bail pivoted on the drum and spring biased form a casting position clear of the line to a winding position where it engages the line. When placed in the casting position a slidable plunger retains the pickup in casting position while ans associated spring biased, friction brake is applied to prevent accidental rotation of the winding drum. When it is desired to wind in the line, rotation of the winding drum causes a stop member to shift the plunger and thereby remove the friction-brake application and permit the biased pickup to move to its winding position.

PATENTEU DECMIBYI B EZKZZB SHEET 1 BF 3 SPINNING WEIIEIL WITH WINDING IDR UM IHBMAIIGE This invention is concerned with a casting reel.

There are known casting reels which comprise an angularly fixed spool, a rotating drum surrounding the spool and a pickup pivoted on this drum and able to be brought from a withdrawn casting position into a pickup position under the action of the drum's rotation when driven by the fisherman, it passes a certain position corresponding to the position of a release stop.

In such reels, it often occurs that during casting the drum accidentally pivots which provokes the unwanted return of the pickup into pickup position. To remedy to this drawback there have already been proposed reels having a device which brakes or stops the drum when the pickup is in withdrawn position.

Some of these reels have a shoe or other braking member fast on the drum and urged against a fixed frictional surface by a spring when the pickup is locked in withdrawn position by a member held by a second spring. Such devices are complicated and therefore costly and subject to going out of order.

Other reels of this type comprise a bent and pivoted braking member acting by one of its extremities against the fixed release cam under the urging of a single spring also tending to maintain the other end against a notch of the pickup in such a way as to prevent the return thereof into pickup position.

When by voluntary rotation of the drum the fisherman exceeds the frictional stress of the braking member against the cam he brings this member to pivot when it meets the release teeth of the cam, which, by liberating the notch of the pickup, permits the tipping thereof.

Nevertheless this arrangement does not give entire satisfaction. In effect it does not allow the braking of the drum except from the moment when the pickup is locked in withdrawn position. Moreover this direct connection of the braking and locking functions causes a very narrow dimensional tolerance for the mechanism since the braking member, practically held immobile by the notch of the pickup, becomes irregular or inoperative in case the fixed cam goes off center. This explains the fact that the braking member is often made to act upon a cam of small diameter which is less likely to have irregularities than a fixed ramp of large diameter which would permit, however, for equal tension, a much more important braking torque.

Consequently, the invention proposes to provide a reel for casting which makes possible a regular and efi'ective braking of the drum when the pickup is in withdrawn position thanks to its simple and foolproof braking device which does not require particular precisions in its dimensions.

To this effect, the invention is concerned with a casting reel comprising an angularly fixed spool, a rotating drum surrounding the spool, a pickup, pivoted on this drum and able to be brought by return means from a withdrawn position to a pickup position, characterized in that is comprises, a sliding member which is guided by the drum and has an extremity which can immobilize an arm fast on the pickup, said sliding member carrying on the one hand a transversal shaft against which can pivot a lever equipped with a braking shoe and urged by a spring in the direction of a cylindrical apron fast on the casing of the reel, and on the other hand a surface permitting the sliding ofsaid sliding member when it meets a fixed return stop of the pickup.

Other characteristics and features of the invention will be later indicated in the following description which refers to the accompanying drawings which illustrate in a nonlimiting fashion:

In FIG. ll an elevation in partial vertical cross section of a casting reel;

In FIG. 2 is a side elevation of FIG. ll;

In FIG. 3, a cross section along III-III of FIG. I which is partially broken away to show some of the elements;

In FIGS. 4i and 5 views similar to FIG. 3 for different positions of certain elements illustrated in that figure.

The reel shown in the drawing (FIGS. II to 3) and which is intended for casting comprises a casing 11 in which is positioned a multiplying device on which only the last toothed gear 2 is visible and the driving of which is possible by the rotation by the fisherman of a handle 3 pivotally mounted at the end ofa boss 6 in casing ll.

This multiplying mechanism actuates on the one hand an alternate axial movement of a shaft 5 at the upper part of which is secured a spool 6 and on the other hand the rotation of a drum 7 through the agency of a pinion 8 cut at the lower end of a sleeve 9 surrounding shaft 5 and meshing with toothed gear 2.

This sleeve is pivoted on a bearing 10, for example a roller bearing, mounted in a ring llll of casing I and surmounted by a disc 112 having a stop B3 on the face thereof facing drum 7. On the cylindrical apron of this drum project two bosses l4 and 113 forming-a support for pickup 116 with a guide with which the reel is provided which is only partially represented in the drawing (FIG. 2). To this efiect, boss 14 is hollowed out with an annular groove ll4a in which fits a spiral return spring 17 secured to the drum by one end and to the arm or ear 16a of the pickup by the other. It is by this ear that the pickup is I pivotally mounted relative to boss Ml, in particular through the agency of a setscrew 18 the part of which near its head forms a cylindrical pivoting shoulder.

Arm 116a carries three members: a break 19a defining the pickup position of the pickup by bearing on a stop 20 of the drum (FIG. 2), a ramp ll9b intended to actuate the axial movement of a plunger 21, for a purpose which will be indicated later, and a window 19c intended to receive the end of plunger 211 when pickup M has been brought into withdrawn position, against the urging of spring 17 to allow locking the pickup in that position.

As shown in the drawing (FIGS. 1 and 3), the plunger 21 is formed of a cylindrical rod carrying a pusher constituted by a sleeve 22a projecting at its lower part. This projection is intended to make possible manual actuation of the plunger, from left to right, against a return spring 23. This plunger slides axially in the drum through the outer surface of sleeve 22a and by its right end in a passage in of the hub of the drum and can be brought by spring 23 from inoperative position (FIG. 3) into locking position of the pickup (FIG. 5) under the urging of the previously mentioned spring 23. This spring is stretched between a fixed stud 23a of the drum and a finger 24in on lever 24 pivoted at 24a on plate 25 fast on plunger 23.

Lever 24 has at one end a shoe 26 of rubber or plastic material having a convex profile the radius of curvature substantially equal to that of the inner envelope of a cylindrical skirt 12a on the edges ofdisc 12.

A shoe 26 integral in rotation with drum 7 is in effect intended to brake this drum when lever 24 is brought into the position of FIG. 3, the shoe 26 rubbing permanently on the ring 12a fast on casing 1.

At its extremity opposite shoe 26, the lever has a beak 241: by means of which it bears on a stop 27 of drum 7 in the posi tion of FIG. 3.

On plate 23 additionally projects a triangular cam 25b extending on the level of stop 13 and at a distance from the pivoting axis of drum 7 such that if the plunger is in the position of FIG. 5 and this drum is rotated it contacts this stop 13 by means of one of the inclined faces in such a way that it is subjected to a radial push directed towards said pivoting axis opposing itself to the action of spring 23 and moving the plunger in the same direction by an amount sufficient to free the left hand extremity of this plunger (FIG. 1) from opening 1% of the ear of the pickup. Under these conditions the pickup which is subjected to the urging of its return spring 17 returns to pickup position (FIGS. II and 2), position which is defined by the meeting of beak ll9a with stop 20.

As we shall see, the constructive characteristics of the reel which have just been described not only allows to proceed to braking the drum solely when the pickup is in the withdrawn position or when the .drum occupies only a determined position but already from the moment that this pickup has been manually moved away from its pickup position and regardless of the position of the drum at that moment.

For this purpose, when the pickup is in pickup position, the plunger rests at the top of ramp 19b and lever 24 then occupies the position illustrated in FIG. 3.

When the pickup is actuated to go to the casting position, the arm of pickup 16a pivots on its axis, ramp 19b no longer contacts the extremity of plunger 21 which results, under the urging of spring 23 and through lever 24 bearing at 24b to bring shoe 26 into contact with the annular track 12a of flange 12 (FIG. 4).

Still under the urging of spring 23, bearing now on show 26, lever 24 leaves its bearing point 24b and causes the ascent of plunger 21 through its shaft 25a until the end of the plunger penetrates into hole [9c of the arm of pickup 16a. In this manner the pickup is locked in open position.

The braking lever, pivoting at 250, urged by the spring, maintains a permanent contact between shoe 26 and braking surface 12a, regardless of the potential decentring of this sur-' face relative to the rotational axis of the drum. The release of the pickup is effected by contact between stop 25b integral with the plunger and fixed ramp 13 integral of disc 12. As long as these two elements do not come into contact, the shoe fulfills its braking function. As soon as ramp [3 urges stop 25a, the plunger comes out of hole 190, the shoe remaining in contact with ring 12, thus frees the pickup which closes under the urging of return spring 17. The end 24b of lever 24 comes to bear against boss 27, cam 19b acts on the extremity of the plunger causing the movement of the shoe away from the frictional surface 12a of tray 12. The antiinertia brake no longer touching the handle of the reel.
