5 Claims, 10 Drawing Figures BOW BRACKET MOUNTING FOR AN ELECTRIC TROLLING MOTOR BACKGROUND AND SUMMARY OF THE INVENTION This invention relates to a bracket for mountingan outboard motor to a boat. More particularly, the invention relates to a bracket for mounting an electric trolling motor on the bow of a fishing boat.

In recent years, fishermen have come to rely on an electric outboard motor, generally known as-a trolling motor, for boating noiselessly through water without alarming wary fish. Power for these motors is commonly supplied by a direct current voltage source, such as a wet cell DC battery, carried aboard the boat.

Electric trolling motors of this type characteristically fall into one of two categories. The hand operated type of trolling motor includes an elongate shaft having a water tight DC motor equipped with a propeller on the work shaft. Electrical leads from the motor extend up through the shaft to a control lever having a handle for rotating the direction of the motor and having a switch and/or speed control for operating the motor. Electrical leads from the control handle are connected to the power source. The second type of trolling motor is commonly referred to as a remote control or foot operated trolling motor and enables the fisherman to have free use of his hands since directional control of the motor as well as on-off operation and/or speed control" is accomplished by the foot acting on a pedal lever which has the necessary switch and any speed control associated therewith.

It is obviously desirable to mount either type of trolling motor onto the boat in such a manner as to enable the shaft and motor unit to be easily placed in the water and to permit removal from the water when it is necessary to employ the standard, combustion-type motor of the boat or when the boat is being transported off the water.

Various models and styles of mounting brackets for positioning a trolling motor in an extended, operating position or in a retracted, nonoperating position are commercially available. These brackets are normally referred to as bow brackets in view of the usual practice of mounting the brackets on the bow of the boat so that operation of the trolling motor may be controlled by a fisherman seated in the forward portion of the boat. The brackets heretofore available have not been without their drawbacks. One of the more serious problems found in commercial models is the tendency of the bracket to vibrate while in the retracted or storage position. In the retracted position, the trolling motor is normally stored on the bow of the boat and is therefore subjected to substantial jolting and pounding as the boat travels over the water. Vibrations of the trolling motor against the bracket and/or the boat itself occasionally damage this equipment. When the boat is trailered for transport on land, the trolling motor is normally retracted and is likewise subjected to extreme bumps and jolts and there have been instances of the trolling motor being blown or torn off of the boatduring travel.

Another significant drawback of commercially available trolling motor brackets resides in the propensity to make noise during the operation of the motor. Although the electric motor itself is virtually noiseless during operation, there is an audible clicking or banging of the bracket when the trolling motor is lowered into the water from the storage position. This loud clat tering is readily transmitted through the water to alarm any fish in the vicinity, thus defeating the purpose of noiseless operation of the electric motor. Also, it is a common practice among fishermen to intermittently, rather than continuously, operate the trolling motor while fishing. In other words, the motor is switched on and off several times rather than being turned on and left on. When the motor is turned on, the thrust of the prop, acting through the trolling motor shaft. causes the bracket to lurge, emitting an audible noise due to the vibration or play in the bracket. These sounds likewise frighten the fish and again can defeat the objective of silent operations.

Accordingly, there is a need in the industry for a trolling motor bracket which eliminates the foregoing defects characteristic of the commercial models heretofore available. The primary goal of this invention is to fulfill this need.

More particularly, an object of the invention is to provide a bracket for mounting an electric trolling motor on a boat and which is adapted to positively retain the trolling motor in a stored position in order to prevent vibrational damage to the equipment as the boat moves rapidly across the water or is transported overland. ln the storage position, the bracket may be locked to prevent movement of the trolling motor from that position.

Another object of the invention is to provide a trolling motor bracket which enables the trolling motor to be noiselessly lowered into the water to an operating position from the retracted position.

Another object of the invention is to provide an electric trolling motor bracket which may be easily and conveniently employed to effect removal of the trolling motor from the water to a retracted position, all such action being accomplished by an operator seated behind the bracket. Furthermore, movement of the trolling motor to a storage position is carried out in one continuous motion without the need of loosening or tightening hand levers or thumb screws such as found on commercial models heretofore available.

An additional object of the invention is to provide an electric trolling motor bracket which may be firmly locked in an operating position and which is completely free of vibrational rattlings and clickings even during intermittent on-off switching of the trolling motor. Combined with the ability of the bracket to silently lower the trolling motor into the water, completely 7 noiseless operation is assured to eliminate the possibility of sharp or metallic-like sounds which tend to alarm and frighten away the fish.

Yet another object of the invention is to provide an electric trolling motor bracket of the character described which is of durable and rugged construction and incorporates features which permit quiet operation throughout a long and useful service life. Biasing members which eliminate vibrational play in the bracket are provided with adjustments, wearing surfaces, and camming surfaces which insure positive latching and locking functions even when various parts of the bracket begin to wear after extended use.

A further object of the invention is to provide an electric trolling motor bracket of the foregoing character and which may be adapted for mounting an electric trolling motor on a wide variety of boat designs. To provide a bracket of a versatile nature, adjustment is provided to vary the distance whichlthe trolliing'motor extends outwardly from the boat in the operating-position while still retaining the beneficial storage and noiseless operation features.

Yet a further object of the invention is to provide a trolling motor bracket of the foregoing nature which may be employed for use with hand operated or remote control types of electric trolling motors.

Other and further objects of the invention, together with the features of novelty appurtenant thereto, will appear in the course of the following description.

FIG. 10 is an enlarged, fragmentary plan view of the storage locking members taken along line 10-10 of FIG. 9 in the direction of the arrows.

Illustrated in the drawings are electric trolling motors of conventional types. The hand operated model 20, such as shown in FIG. 7, includes a control housing a having a lever 20b for controlling the direction of the motor and such additional controls as an on-off switch 20c and, if the model is so equipped, controls for varying the speed of the motor. Electrical leads 20d from the housing 20a may be connected to a power supply such as a DC battery (not shown). An elongate shaft 201' extends from the housing 20a and is connected to motor and propeller unit 20f. A slidable split collar 20g encircling the motor shaft 20e may be securely fixed at any position on the shaft 20e in order to vary the depth to which the motor 20f extends into the water.

In the remote control model 21 as shown in FIG. 1, the motor likewise includes an electrical lead 21a from the upper housing 2112 which may be connected to a battery power source and an elongateshaft 21c which has mounted on its end an electric motor and propeller unit 21d. However, unlike the hand operated model 20, the remote control model2l is fitted with a directional control housing 21e having a rotatable collar 2Ifwhich receives the motor shaft 21c. The shaft 21c is releasably secured by the collar 21fto vary the depth to which the motor 21a extends into the water. A cable 21g leads from the control housing 21a to a foot pedal mecha nism 21h which may be depressed by the operator seated in the boat in order to cause the collar 21fto rotate and thus vary the direction of the motor 21d. The foot control mechanism 2111 is also equipped with an on-off switch which may be depressed in order to activate the motor 21d. With this model 21, both the on-off operation as well as directional control may be accomplished by the foot of the operator.

Referring to the drawings with respect to the bow bracket 22 itself, the bracket includes a base portion having an elongate, upturned channel member 23 with a flange plate 24 connected on the undersurface and which is secured to the bow of the boat 25 by a plurality of bolts or screws 26. In the latter regard, it is customary to mount trolling motors on the bow of a boat. Nevertheless, the bracket herein disclosed may be mounted at other locationsinthe boat if desired, such as at the stem or along the sides.

Mounted on the forward end of the base channel 23 by means of bolts, nuts and locking washers are a pair of upstanding C-shaped members 27. One such C- member 27 is mounted on each vertical side portion of the base channel 23 and is so oriented that the mouth of the C opens in a direction forwardly and outwardly of the base channel 23. The motor engaging edges of the C-members 27 are covered with resilient padding 28 such as a rubber or flexible synthetic composition. The padding 28 is secured to each C-member 27 by side plates 29 which are riveted together as shown in FIG. 2. The forward edge of the exposed base channel 23 is also covered by a resilient protector strip 30.

Toward the rearward portion of the base channel 23, a plurality of paired holes 31 are provided in the vertical side walls of the base channel 23. Each pair of holes 31 are laterally aligned through the base channel 23 and successive pairs of holes 31 are longitudinally spaced apart a uniform and preselected distance.

Received between the vertical side walls of the base channel 23 is an elongate pivot arm 32 which is formed of channel stock and is inverted with respect to the base channel 23, as shown in FIG. 6. The rearward end of the arm 32 is hingedly connected to the base channel 23 by a shaft 33 which extends through the second pair of holes 31 from the end pair in the base channel 23 and through a first pair of holes (not shown) in the end of the pivot arm 32. As shown in FIGS. 3 and 6, spacer blocks 34 are disposed between the vertical walls of the arm 32 and the base channel 23 to keep the pivot arm 32 centrally aligned in the base channel 23. Rubber grommets 35 installed in the side walls of the base channel 23 also assist in alignment of the arm 32. A second pair of holes 36 extend through the side walls of the pivot arm 32 (see broken line view of FIG. 2) and are spaced apart from the first pair of holes near the end of said arm 32 a distance equivalent to the spacing of the hole pairs 31 in the base channel 23.

On the outer end of the pivot arm 32 a motor shaft clamp 37 is releasably hinged for limited pivotal movement with respect to the arm 32. Illustrated in FIGS. 2, 3, 4, 7, 8 and 9 is a shaft clamp 37 for a hand operated electric trolling motor 20. FIG. I illustrates the retaining member 37' for a remote control trolling motor 21.

First, with respect to the hand operated trolling motor 20, the shaftclamp37 comprises a split bearing sleeve 38 which receives the shaft c of the trolling motor 20 and which is fitted with a hand lever 39 for tightening the sleeve 38 to grip the motor shaft 20c. A projection 40 to the rear of the bearing sleeve 38 is pivotally pinned to the pivot arm 32 by a bolt 41 with an elastic self-locking stop nut 42 (FIG. 3). The rear projection 40 of the shaft clamp 37 forms an overlying shelf 43 which mates with a notched out portion 32a in the forward end of the arm 32 (FIG. 8) so that the top surface of the arm 23 and the top surface of the shelf 4-3-are flush when the clamp 37 is locked in the operating position (FIG. 5). The back edge of the shelf 43 is covered by a wear plate 44 riveted through the shelf portion.

Rearwardly of the notched out portion 32a in the upper surface of the arm 32 is disposed a releasable latch 45 for retaining the motor shaft clamp 37 in a locked position. As shown in FIG. 5, the latch 45 includes a plate 46 installed on the upper surface of the arm 32 for limited movement. The plate 46 is connected by screw members 47 which are received in elongate slots 48 permitting forward and backward movement of the plate 46. A recess in the underside of plate 46 receives a compression spring 49 which operates against a stop 50 attached to the arm 32 to bias the plate 46 to a forward position extending over the upper edge of the arm 32. A ring 51 is connected to the rear of the plate 46 and is equipped with a length of rope or cord 52 providing a pull. The free end of the pull 52 is tied to a hitch pin 53 of essentially the same diameter as the holes 31 in the base 23 and the holes 36 in the arm 32.

The forward face 46a of the plate 46 is inclined for engagement with the shelf portion of the shaft clamp 37 (FIG. 5 broken line view) to permit the plate to be moved against the action of the spring when the retaining member is rotated to the latched position. The under surface. 46b of the plate 46, which extends outwardly into the notched out portion 320 of the arm 32, is slightly tapered to provide a camming surface for engagement with wear plate 44 mounted on the edge of the shelf 43.

With respect to the remote control model 21, the control cable housing 21a is fitted with a rearwardly extending projection which is pivotally connected to the forward end of the pivot arm 32 and has a shelf mem her which overlies the notched out portion of the pivot arm in the, same manner and in identical construction as previously described with reference to the shaft clamp 37 for holding the motor shaft of the foregoing hand operated trolling motor.

Mounted alongside the base channel 23 by means of a fixed platform member 54 is a toggle clamp 55 having an arm 55a on which is adjustably mounted a compression foot 55b adapted to engage a resilient compression pad 56 secured on the upper surface of the pivot arm 32. The hand lever 550 of the toggle clamp 55 may be employed to biasingly lock the foot 55b to engagement with the compression pad 56 when the pivot arm 32 is rotated to the extended, operating position. Alternatively, the lever 550 is adapted to rotate the compression foot 55b to the side in order to permit raising of the pivot arm 32.

In order to fully utilize the operational capabilities of the bow mounted electric trolling motor bracket disclosed herein, it is first necessary to adjust the bracket to the physical characteristics of the specific trolling motor to be used. Basically, in the case of the hand operated trolling motor 20, this requires adapting the distance between the depth control collar 20g on the motor shaft 20c and the motor unit 20f to match the distance between the C-shaped members 27 and the end of the pivot arm 32 when the pivot arm is disposed in the storage position (i.e., being rotated approximately l from the operating position as shown in FIG. 9). This adjustment may be easily effected by positioning the pivot arm 33 in thestorage position and locking the pivot arm 32 in such position by inserting the hitch pin 53 through the holes 3] in the base channel 23 and the holes 36 in the pivot arm 32 as shown in FIG. 10. The motor and prop unit 20f is then snugly nested in the mouth of the C-members 27 and the loosened collar 20g is pushed against the upper surface of the bearing sleeve 38 and secured in place by tightening the bolts or set screws associated with the collar.

At this point, it should be noted that the distance which the motor and prop unit 20f extends into the water is determined by the distance between the C- clamps 27 and the shaft clamp 37. This distance may be varied, however, by moving the pivot point of the arm 32 closer to the C-members 27 in order to shorten the distance the motor 20fextends into the water. Such may be accomplished by removing the pin 33 extending through the second inward pair of holes 31 in the base channel 23 and through the endmost set of holes in the pivot arm 32 and remounting the pivot arm 32 in a pair of holes 31 closer to the C-clamps 27. It will also be noted that this adjustment, in effect, additionally causes the end of the pivot arm 32 on which the trolling motor is mounted to extend out from the boat a greater distance.

From the storage position as indicated in FIG. 9, should it be desirable to move the trolling motor 20 to the operating position, one need only remove the hitch pin 53 from the aligned

holes

31 and 36 of the base channel 23 and pivot arm 32 and rotate the pivot arm 32 approximately and to lock the shaft clamp 37 underneath the latch member 45. The latter operation a is accomplished simply by rotating the shaft clamp assembly 37, which may be achieved by a rearward force applied to the control head 20a of the trolling motor which, in turn, causes the lower edge of the shelf 43 to engage the inclined front surface 460 of the plate 46 (broken line view in FIG. 5) and to move the plate 46 against the force of the spring 49 until the shelf 43 passes the plate 46. Acting under the force of the spring 49, the plate 46 then moves forward to engage the upper edge or wearing plate 44 of the shelf 43. Any play or looseness in the engagement between the pivot arm 32 and the shaft clamp 37 causes the latch plate 46 to move forward under the influence of the spring 49 and to further snugly engage the shelf 43 by the camming surface 46b in order to eliminate vibration between the parts.

When the pivot arm 32 is disposed in the operating position, the toggle clamp 55 may be locked in place to bias the pivot arm 32 to snug engagement with the channel member 23.

Normal operation of the hand operated trolling motor 20 is now carried out including the normal start andstop actuation of the motor f, as well as speed variation if the motor is so equipped, and directional control accomplished by the movement of the hand lever 20b. Should it be desirable to temporarily lock the motor in a specific direction, the hand lever 39 associated with the split sleeve bearing 38 may be tightened against the motor shaft 20c so as to prevent rotation. If it is then desirable to manually control the direction of the motor 20f, one needs only loosen the hand lever 39 to resume normal operation and to permit rotation of the motor shaft 20e within the bearing sleeve 38.

in the event it is desired to move the trolling motor 20 to the stored position, as for example when changing general fishing locations requiring the need of the normal combustion type motor of the boat, one need only rotate the toggle clamp 55 to the side and then grasp the pull cord 52 and supply a rearward force which removes the latch plate 46 from engagement with the shelf area 43 of the shaft clamp 37, thus causing the motor shaft 202 to pivot inwardly and the shelf member 43 to pivot out of engaging alignment with the latch, while simultaneously supplying an upwardly rotational force to the forward end of the pivot arm 32. As the pivot arm 32 is rotationally lifted in an arc, the shaft 20a of the trolling motor engages the forward padded edge of the base channel 23. The arm 32 is pivoted to the rear until the motor housing 20f engages the rounded shoulder of the C-member 27 causing the motor 20f to ride upwardly into the mouth of the C- clamps 27. The motor housing 20f is snugged to engagement with the C-clamps 27 when the pivot arm 32 is fully rotated to the stored position (approximately 180 from the operating position). The bracket 22 may be left in the storage position as described until it is desirable to again deploy the trolling motor 20 to the operative position. If the water is extremely rough or the boat is being transported on land, it is desirable to insert the hitch pin 53 in the aligned

holes

31 and 36 of the base channel 23 and pivot arm 32 in order to prevent pivoting of the arm 32 due to bumps and bounc- Both the initial adjustments to and operational aspects of the bracket 22 mounting a remote control type of trolling motor 21 are essentially the same as that described with reference to the hand operated model 20. The only difference, of course, resides in the characteristic features of the remote control unit 21. Specifically, the control housing 2le, well familiar to those skilled in this art, is adapted to pivot on the forward end of the pivot arm 32 and is equipped with a projection 37' having a shelf area which overlies the notched out portion 320 of the arm 32 as previously described with respect to the rear projection of the shaft clamp 37.

lt should be readily apparent that in the stored position, the motor and propeller unit is securely retained in the mouth of the C-clamps and is cushioned therein by means of engagement with the resilient pads in order to prevent damage to the motor or housing. When the motor is locked in the stored position by means of the removable hitch pin, the possibility of accidental rotation of the bracket or displacement of the trolling motor is completely eliminated, to ensure safe, damage free transit.

It should also be noted that various features of the bracket are specifically designed to ensure silent operations during fishing conditions. This is evident not only in lowering and raising of the motor in the water, but

also in the on-off switching of the electric motor itself. When the motor is lowered into the water, the pivot arm engages the resilient pad and quiet alignment between the vertical walls of the base channel is assured r by virtue of the guiding and spacing grommets located between the side walls of the pivot arm and the base channel. No metal to metal contact is required in dropping the pivot arm onto the base channel. Vibrational noises caused by play in the bracket are completely eliminated in this design. It is noted that the toggle clamp biases the pivot arm to engagement between the resilient pad mounted on the forward edge of the base channel and the compression pad engaging the toggle clamp on top of the pivot arm and therefore, play or looseness between the base channel and the pivot arm is eliminated. Likewise, play or looseness between the motor shaft retaining assembly 37 or 37' and the pivot arm is eliminated by the camming action of the latch plate which works to tighten engagement with the shelf area.

From the foregoing, it will be seen that this invention is one well adapted to attain all the ends and objects hereinabove set forth together with other advantages which are obvious and which are inherent to the structure. I

it will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
