FIG.4

GEORGE E HORTON INVENTOR AT TO RNEY BRACKET FOR MOUNTING BOAT ACCESSORY This invention relates to handling equipment for small boats and has reference to an outwardly extensible hinged bracket for placing a boat accessory in operation in the water and for retracting the bracket and the accessory when the latter is not in use. Although the invention is capable of handling various accessories, for example, anchors and over the side ladders, it is particularly useful for placing small electric outboard motors in the water in operating position and for mounting the motor on the boat when the motor is not in use. Electric outboard motors as herein referred to are usually in addition to other and more powerful means for propelling a boat and the electric outboard motor is used for trolling and fishing in shallow waters without using the more powerful and noisier propelling means. Such electric motors are remotely controlled by an occupant of the boat and the controls for rotating the motor for moving in a desired direction may be by an electrical cable or by a flexible cable and pulley arrangement, both of which are conventional and are only incidently a part of the present invention.

An object of the invention is to provide a convenient and easily operated outwardly extensible hinged bracket for mounting a boat accessory on a small boat.

Another object of the invention is to provide an outwardly extensible hinged boat accessory bracket having a cushion for supporting the accessory when the bracket is in its retracted position.

Another object of the invention is to provide an extensible boat accessory bracket which operates on the principle of a hinged parallelogram and whereby the accessory is in at least a generally horizontal position when the bracket is retracted.

These and other objects of the invention will become apparent from the following description and the accompanying drawing, in which:

FIG. I is a side elevational view of the forward position of a boat and showing the present bracket mounted thereon in its retracted position.

FIG. 2 is an enlarged side elevational view of the bracket in its extended position and showing an electric outboard motor mounted thereon.

FIG. 3 is a view similar to FIG. 2 but shows the bracket in an intermediate position.

FIG. 4 is a sectional view taken on line 4-4 of FIG. 2, and

FIG. 5 is a plan view of the mounting plate and cushion and showing broken lengths of the link arms pivotally connected to the plate.

The boat shown in the drawing is exemplary and includes a forward deck 11 on which the present bracket 12 is mounted. However, it is to be understood that bracket 12 may be mounted on other parts of the boat such as by clamping the bracket on the transom, not shown. The top of the back of a seat 13 in which the operator sits is also shown in FIG. 1.

The bracket 12 includes a rectangular horizontal mounting plate 14 having parallel vertical sides 15, and on the outer surface and near the inner end of which sides a pair of link arms 16 are pivotally attached by bolts 17 which form a first pivot axis. The end of the mounting plate 14 opposite the last referred to pivotal connections projects beyond the sides where it is provided with a cushion 18 on the extending upper surface. The cushion 18 is of sponge rubber or other suitable resilient material. Between the mounting plate sides 15, and in the end portion nearest the cushion 18, there is an additional link arm 19 which is pivotally secured at one end between the said sides by a pivot pin 20 which forms a second pivot axis. For reasons which will become apparent, the ends of the pin 20 are flush with or recessed in the outer surfaces of the mounting plate sides 15. For purpose of identification, the first referred to link arms 16 are herein referred to as the inner arms, and the second referred to link arm 19 is referred to as the outer arm. The outer arm 19 is nearly as wide as the distance between the mounting plate sides 15 and for this reason the sides of the arm are notched to clear the heads of the bolts 17 which mount the inner arms 16. See FIG. 5. Bolt holes 21 are also indicated in FIG. 5 for receiving bolts, not

shown, when securing the mounting plate 14 on the boat deck 1 1.

On the extending ends of the inner and

outer link arms

16 and 19 there is a channel shaped support 22, and on the outer surface of the web of the support there is, as by welding, a clamping sleeve 23 for engaging the tubular portion 24 of the housing of an electric outboard motor 25. The tubular portion 24 of the motor 25 is adjustably secured in the clamping sleeve 23 by a bolt 26 in outwardly projecting parallel integral ears 27. The outboard motor 25 shown is conventional and is not, therefore, herein described in detail; however, it is pointed out that the upper housing 28 contains means for selectively rotating the drive motor 29 and propeller 30 thereon for directing the boat 10 in the water.

Referring now to the channel shaped support 22 in detail, the inner link arms 16 (which appear as upper arms in FIG. 2) are pivotally connected with the outer surface of side of the support near the end thereof by a single bolt 31 which forms a third pivot axis. Preferably, the support. 22 has projecting ears 32 to receive the bolt 31, and there is a tubular sleeve 32 around the bolt for attaching a flexible pull cord 33 which extends to the operators seat 13. The extending end of the outer link arm 19 is received between the sides of the support 22 and is pivotallyattached by means of a pin 34, the ends of which are preferably flush with said sides. Pin 34 forms a fourth pivot axis. The distance between the last described bolt 31 and pin 34, relative to the distance between the first described bolt 17 and pin 20 in the sides 15 of the mounting plate 12, is such that the

link arms

16 and 19 are substantially parallel when the arms are in an upright position. Also, the length of the outer arm 19 is less than the length of the inner arms 16 whereby the length of the outboard motor 25 is nearly horizontal, as shown in FIG. 1, when the bracket 12 is retracted. Also at this time the outboard drive motor 29 rests on the cushion 18.

When transporting the boat 10, as on a trailer, or when the boat is in the water and propelled by a primary source of power, the bracket is in its retracted position. To submerge the propeller 30 the operator initially raises the bracket 12 by hand until the

link arms

16 and 19 are just beyond their vertical positions. The bracket 12 is then lowered by the pull cord 33 until the outboard motor 25 assumes a vertical position as shown in FIG. 2, after which the motor is operated by means of a control cable 35 in the usual manner. To retrieve the outboard motor 25 the bracket 12 is retracted by pulling on the cord 33.

The invention is not limited to the exemplary construction herein shown and described but may be made in various ways within the scope of the appended claims.
