Specification of Letters Patent.

Patented Aug. 18, 1914.

Application filed December 6, 1913. Serial No. 805,011.

' To all whom it may concern ":d .position, thereby reducing the space otherwise necessary for storage purposes.

Another object is.:to. provide a foldable rudder, the bracket ofwhich may constitute, when the rudder is folded position, one member of a three support for the mo-. tor and parts connected thereto.

The invention consists in a rudder that is connected to the rudder shaft of an outboard motor in such manner as to be readily turned from a position substantially parallel to the rudder shaft to a position at substantially right angles thereto.

This invention also consists in means whereby the rudder shaft may be adjustably mounted on the rear end of the boat.

It further consists in the novel details of v construction shown and described and particularly pointed out in the claims.

, the rudder.

Similar reference characters refer to like parts throughout the-several views.

In the drawings, 1 indicates a well known form of bracket to hold a motor in position upon the rear end of a boat. Supported upon the bracket, by means of trunnions 2, is a motor 3 and a fuel chamber 4 that may be provided with lugs 5 upon its rear surface. Connected to the motor is a motor shaft casing 10, which is also supported upon the bracket 1, preferably my means of the split bracket 11, and projects downwardly from the crank case, its lower end being adjustable to and from the rear end of the boat by means of the slotted connection 12. This connection consists of a pair of slotted members, one on each side of the motor shaft, that are mounted to swing in a vertical plane on the pin 15 passing through a perforation in the lower end of the bracket 1. The motor shaft casingand rudder carried thereby may be clamped in any position of angular adjustment by means of the bolt 30 and thumb-nut 31. Within the tubular casing, 10 is a motor shaft 13 (Fig. 2) that turns thescrew 14 at the lower end of the casing.

The parts thus far described, with the exception of the lugs 5 and the slotted connection between the bracket and the motor shaft, are well knownl Mounted to turn upon the sleeve 10, at a point preferably just below the crank case, is a tiller rod 16 having at its forward end a handle 17 and at its rear end a gear segment 18 that engages with a gear segment 19 se-. cured to the upper end of a rudder shaft 21, the latter preferably being carried by the brackets 11 and 22 upon the casing 10. The rudder shaft has rigidly secured thereon,

preferably atits lower end, a rudder bracket 23 that is provided with a split outer end 24 having a shoulder 25 formed upon its lower side, as shown in Fig. 3. The end 24 is per forated to receive a pin 26 and mounted to turn upon this pin and between the halves of the split end is a rudder blade 27 that is, provided upon its lower edge with a lug 28 which is adapted to contact with the shoulder 25 and thereby limit the angular adj 11stment of the blade. The blade 1s preferably tightly gripped by the halves of the end 24, which prevents accidental displacement, but at the same time allows the blade to be turned from the. dotted line position to that shown in full lines in Fig. 1. In use the blade is in the position shown in dotted lines.

If it is desired to store away the motor, it isdeta'ched from the boat,.and the rudder is then swun into the full line position, after which t e motor may be supported in,the bottom of the boat or elsewhere by means of the lugs 5 and the outer end of the rudder bracket 23. v

Any desired changes may be made in the details of the device without departing from the spirit of my invention as expressed in the claims.

Having now described my construction," what I regard as my invention and desire to secure by Letters Patent is z- 1. In combination, a support, a motor shaft casing carried thereby, brackets secured on the casin and having alined bearlngs, a rudder sha t mounted 'to turn in, the bearings, means to turn the rudder shaft, a

- rudder bracket secured to therudder shaft a fuel chamber carried thereby, lugs projecting from the fuel chamber, a bracket secured to the casing and having a bearing formed therein, a rudder shaft mounted to turn in the bearing, a rudder bracket secured to the rudder shaft, :1 foldable rudder connected to the bracket, said rudder bracket and said lugs being adapted to constitute a support for the motor when the rudder is in folded position.

3. In combination, a support, a motor shaft casing carried thereby, a bracket mounted on the support and having a bearing therein, a rudder "shaft mounted in the bearing, means to turn the rudder shaft, a

rudder bracket secured to the rudder shaft tact with each other to limit the movement 7 of the rudder in one direction.

4. In combination, a support, a motor shaft casing carried thereby, a bracket mounted on the support and having a bearing therein, a rudder shaft mounted in the bearing, means to turn the rudder shaft, a rudder bracket secured to the rudder shaft to turn therewith, a rudder pivotally mounted on said rudder bracket, and means on the rudder co-acting with means on the rudder bracket for limiting the movement of the rudder in one direction.

In testimony whereof I have signed this specification 1n the presence of two subscribing witnesses.
