Brake for fish casting reel

The reel is of the fixed spool type with rear brake, and comprises a drive shaft a first end of which supports the spool, a main spool brake with an operating member actuatable from the rear of the reel by the user, an auxiliary braking lever comprising a grippable part forming a control member for pushing a braking member against a braking surface of the shaft, wherein a resilient transmission means is inserted directly between the grippable part of the auxiliary braking lever and the braking member for transmitting the auxiliary braking force, and the auxiliary braking lever is urged by resilient return means bringing it back to the rest position.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to casting reels for fishing and in 
particular to those having a fixed spool and a rear brake controlled from 
the reel. 
2. Description of the Prior Art 
FIG. 1 shows a sectional view of a reel of this type widely known and used. 
In this reel, the line reserve called spool or drum 1 is a part 
substantially of revolution formed from two radially extending side-plates 
joined together by a cylindrical hub extending axially from one side-plate 
to the other. The axis of the reel is approximately parallel to the 
spooling off direction of the line. The line spool is secured against 
rotation both for casting and for winding in. A crank handle causes a line 
recovery winder to rotation which rotates about the spool and winds in the 
line. 
In most of the reels of this type known in the prior art, the spool is no 
longer fixed if the tension in the line exceeds a limit value chosen by 
the angler. For this, spool 1 is connected to the reel housing 13 through 
a kinematic chain which comprises at least one strain limiting device, 
also called brake. Spool 1 is fixed on shaft 2 by a clip 3 and a groove 4 
engaging respectively with groove 5 and the pin 6 of the shaft. The shaft 
reciprocates axially with a translational movement under the action of a 
line winding system not shown in the Figure. The shaft thus slides to its 
other end in a sleeve 8 with which it is interlocked for rotation by two 
flats 7 on the shaft in engagement with corresponding internal flats in 
the sleeve 8. The outer surface of sleeve 8 comprises two flats 9 and 
receives washers 10 whose central hole has a section corresponding to the 
external section of the sleeve for sliding axially thereon without 
possibility of rotating. The sleeve comprises a flange 11 bearing against 
a stop forming part 18 of the housing 13 and on a cylindrical bearing 
surface 12 engaged in a bore of this same part 18 of the housing for 
centering the sleeve. Washers 14, fitted loosely on the sleeve and 
inserted between washers 10 have a radial extension which engages in a 
groove 15 in the housing for preventing rotation thereof. Washers 10 and 
14 have appropriate friction properties. The sleeve 8, washer 10 and 
washer 14 assembly is axially compressed between the stop forming part 18 
of the housing and a first spring 17 tensioned by a nut 16 for adjusting 
the braking torque. 
Nut 16 is accessible from the rear of the reel so that there is no risk of 
mistaking it for the reel changing means, generally disposed at the front; 
it can be readily gripped because of its suitable size, and it is not 
disturbed by the presence of the line. 
Limiting the tension of the line by means of the brake meets first of all 
the requirement of not breaking the line if the fish is too active to be 
brought in by force and must be played before being put into the landing 
net. Secondly, anglers have discovered that it is possible to catch some 
kinds of fish which take the bait very rapidly but release it if they feel 
the slightest resistance, by choosing a very low value for the maximum 
tension of the line. However, this method leads to many operations which 
may give rise to mistakes, for then this maximum tension must be increased 
for striking, playing, winding in the fish and putting it in the landing 
net. Furthermore, in some cases this value must be increased, for example 
so as to free the bait from an obstacle on which it is caught. 
Patent No. FR-E-77644 to Rouanet divulged a reel with main brake controlled 
from the side by means of a screw urging, through a spring, a brake shoe 
against the outer surface of a cylinder interlocked for rotation with a 
spool. This device further comprises an auxiliary brake, actuated by a 
lever one end of which is controlled by the operator and the other end of 
which bears on the main brake shoe. 
Such a device provides the auxiliary brake functions but has major 
drawbacks which have prevented its commercial development: thus, the 
auxiliary brake lever has a practically zero travel range, which makes 
adjustment of the braking torque very difficult, especially in the fishing 
sphere where one must react rapidly and accurately; furthermore, no means 
is provided for limiting the auxiliary braking torque, and it has been 
discovered that the use of such a device leads to frequent breaking of the 
line: in addition, the imbalance of the lever produces, through the effect 
of its weight, parasite braking due to the orientation of the reel. It 
will be noted that this auxiliary brake structure is not directly 
applicable to a main brake of the washer type. 
The aim of the present invention is particularly to provide additional 
braking means in which the range of travel of the lever is not zero and is 
also independent of the adjustment of the rear brake. The user is in fact 
better able to regulate the braking force by adjusting the position of the 
lever rather than the pressure exerted thereon by hand. These means may be 
actuated by a resilient return lever providing immediate and simple 
efficiency. 
With the invention, this additional braking is provided with a very few 
additional parts, more especially by using certain parts of the rear brake 
playing a double role and in a structure compatible with reels having a 
rear brake of the washer type. 
Another advantage of the invention is that the position of the lever is 
independent of the adjustment of the rear brake and in particular its rest 
position is always the same. The angler may thus feel the additional 
braking which he is causing through the force he exerts on the lever. 
Moreover, it is important that there should be no additional braking when 
the lever is not actuated. 
With the braking means of the invention, the additional braking torque may, 
in particular, be made substantially proportional to the movement of the 
lever alone, independently of the setting of the rear brake and over the 
whole of the usual braking range of this brake. 
Breakage of the line is avoided in accordance with the invention by 
providing means constantly limiting the maximum additional braking torque 
provided by the additional brake. 
SUMMARY OF THE INVENTION 
To attain these objects as well as others, according to the present 
invention, in a rear brake reel of a known type comprising an auxiliary 
brake producing an adjustable additional braking torque applied to the 
sleeve of the rear brake by means of a braking member urged by an 
auxiliary braking lever having a part which is accessible and may be 
gripped by the user: 
a resilient transmission means is inserted directly between the grippable 
part of the auxiliary braking lever and the braking member, for 
transmitting the auxiliary braking force, 
the auxiliary braking lever is urged by resilient return means bringing it 
back to the rest position, so that the rest position of the auxiliary 
braking lever is constant, the influence of the weight of the lever is 
inhibited, the range of travel is not zero, the maximum value of the 
additional braking torque is limited and the stiffness of the auxiliary 
braking lever is practically independent of the setting of the main brake. 
According to another feature of the invention, the lever is mounted for 
oscillation between a first fixed stop on the housing against which it is 
returned by the resilient return means and a second fixed stop on the 
housing limiting its maximum travel; thus, the combination of the second 
fixed stop and the resilient transmission means limits more accurately the 
compression force produced by the lever on the braking member and prevents 
any excessive additional braking torque, which would cause the line to 
break.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
In the following description, parts similar to those of the prior art reel 
shown in FIG. 1 have been shown with the same references. 
In the reel of the present invention shown in FIGS. 2 and 3, the rear brake 
has exactly the same construction as in the known devices shown in FIG. 1. 
The reel of the invention comprises an auxiliary braking lever 20, 
pivotably mounted to housing 13 by a transverse rotational shaft 21. The 
lever is disposed in a longitudinal position substantially parallel to the 
rod on which the reel is to be mounted, so that it may be directly 
operated by the hand holding the rod. 
Lever 20 may rock between a first fixed stop 22 on housing 13 and a second 
fixed stop 23 on the housing. A connecting rod 24 transmits the movements 
of lever 20 to the first end 25 of a second spring 26, a traction spring, 
whose second end 27 is hooked onto a rocking lever 28. 
Connecting rod 24 comprises an inner threaded portion 29 in which is 
engaged a threaded screw 30 for adjusting its length. A third spring 31, a 
compression spring, has one end bearing against a shoulder 32 of the 
connecting rod 24 and a second end bearing against housing 13. The third 
spring 31 together with the second spring 26 exert a force on lever 20 
returning it to the first fixed stop 22 of the housing, in which position 
the lever is at rest and spring 26 has zero tension. Furthermore, the 
third spring 31 substantially improves the sensory effect felt by the user 
when he operates the lever: in fact, in the absence of a third spring 31, 
for producing the desired additional braking, a low traction force 
provided by spring 26 is sufficient, corresponding to a bearing force F of 
about 50 to 100 Newton at the end of the lever. Spring 31 is chosen so as 
to have a prestress or residual non zero tension in the rest position of 
lever 20, and a stiffness such that an increasing force from about 40 
Newton to about 150 Newton must be applied to the end of the lever so as 
to move it from the rest position to maximum braking. Thus, the user feels 
safe and braking changes which are too sudden are avoided because of the 
required minimum threshold and because of the substantial increase of 
force which must be exerted by the user for operating the lever. 
By actuating lever 20, a traction force is generated on rocking lever 28, 
which force is transmitted by the connecting rod 24 and spring 26. At the 
end of travel, when lever 20 comes into abutment against the second stop 
23, the traction force exerted on rocking lever 28 is maximun and is 
defined by the second spring 26. 
The rocking lever 28 comprises a first end 33 to which spring 26 is hooked 
and a second end 34 pivotally linked to housing 13. The rocking lever 28 
may rock about its second end 34 by actuating the lever. 
In the embodiments shown in the Figures, the second end 34 of the rocking 
lever bears unidirectionally on a shoulder 35 of the housing. 
Rocking lever 28 comprises a central projecting part 36 in contact with the 
stack of washers 10 and 14 and adapted for pushing the washers back 
against stop 18 of the housing, under the action of one or both springs 17 
and 26. 
Rocking lever 28 may have the form of a washer, i.e. with the central 
aperature for free passage of sleeve 8. In a first alternative, the 
central aperture is sufficiently large to let spring 17 also pass 
therethrough which comes into abutment either directly, or through a 
pusher not shown, against the first washer of the stack of washers 10 and 
14; in another alternative of the invention, the central aperture is 
smaller so that spring 17 or its pusher is in abutment against the rocking 
lever 28, itself abutting against the stack of washers. Rocking lever 28, 
then inserted between spring 17 and the stack of washers, transmits the 
pressure exerted by spring 17 of the rear brake. 
The operation of the device is as follows: in the rest position of lever 
20, i.e. in abutment against stop 22 under the action of spring 31, the 
force transmitted by the second spring 26 to the rocking lever 28 is zero. 
The only braking torque is generated by the rear brake, i.e. by adjusting 
nut 16 compressing spring 17 which itself compresses the stack of washers 
10 and 14. 
When the rear brake generates a given braking torque, lever 20 may generate 
an additional braking torque: by actuating the lever, the connecting rod 
24 tensions spring 26 which transmits a traction force to rocking lever 28 
itself causing an increase in compression of the stack of washers 10 and 
14. The effect exerted by lever 20 is limited by the combination of stop 
23 and spring 26. In the largest part of the operating zone of the rear 
brake, the additional braking torque is substantially proportional to the 
angular movement of lever 20. 
In FIG. 3 it can be seen that housing 13 comprises two parts, a first part 
40 on which a second lid-forming part 41 is fitted. Washers 10, rotary 
washers, are mounted for sliding on sleeve 8 with respect to which they 
are locked against rotation by flats. Washers 14, or fixed washers, are 
free to rotate and move in translation with respect to sleeve 8, and slide 
with respect to housing 13 in which they are secured against rotation by 
engagement in corresponding grooves 42 and 43 in the housing. For that, 
washers 14 have a substantially rectangular section, better shown in FIG. 
3, and a central circular hole 44 having a diameter greater than the outer 
diameter of sleeve 8. Washers 10 on the other hand have a circular section 
with an outer diameter less than the distance separating the bottoms of 
grooves 42 and 43, and a central hole whose section comprises flats and 
corresponds to the outer form of the portion of sleeve 8 on which they are 
engaged. In the embodiment shown in FIG. 3, each of the two parts 40 and 
41 of housing 13 comprises one of the two grooves 42 and 43. 
Washers 10 and 14 may be single or multiple and may be separated by 
intermediate washers made from a material having a suitable friction 
coefficient, such for example as: leather, polytetrafluorethylene, 
asbestos, felt, etc. 
The present invention is not limited to the embodiments which have been 
explicitly described, but includes the different variations and 
generalizations thereof contained within the scope of the following claims
