OUTBOARD MOTOR.

Application filed August 31. 1921, Serial No. 497,101.

To all whom it may concern.

Be it known that 1, WILLIAM I. A. Brrrr NER, a citizen of the United States of Amer ica, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Outboard Motors, of which the following is a. specification, reference being had therein to the accompanying drawings.

The primary object of my invention is to provide novel supporting means for an outboard mot-or for a boat propeller so that the motor or propeller may yield when encountering obstacles thereby preventing the motor and its propeller or the supporting means of the motor from being broken or injured.

Another object of this invention is to provide a tiltable outboard motor and positive and reliable means for holding the tiltahlc motor in an operative position. also in a position to which it may be tilted, particularly when encountering an obstacle.

A further object of this invention is to furnish an outboard motor with a novel steering mechanism l) which a rudder may be adjusted. the steering mechanism including a rotatable member. in contradistinctiop to a tiller, and the location of the rotatable member is such as not to occupy valuable space in a boat and permit of the operator of a boat easily and quickly operating the rudder thereof.

A still further object of this invention is to provide certain improvements in conned tion with an outboard or row boat motor hich Will render such motor more practical and afford a wider range of boat travel, in somuch that waters may be traveled with the assurance that the, motor will not be fouled by running aground or encountering obstructions.

The improvements which I have devised will be hereinafter described and then claimed, and reference will now be had to the drawings, Wherein- Figure 1 is a side elevation of an outboard motor in accordance With this invention:

Fig. 2 is a. front elevation of the same;

Fig. 3 is an enlarged detail sectional view of a yieldable interlocking member forming part of the motor support, and

Fig. 4 is a horizontal sectional view showthe steering mechanism.

11 order that my improvement may be easily understood, l have illustrated a coin ventional form of outboard motor or engine Renewed May 7, 1923.

1 having a crank case 2 and a depending connection 3 to a combined propeller housing 4 and rudder support or propeller guard 5, the propeller housing 4 supporting a propeller 6 which is operated from the motor 1 through the depending connection 3. On the sup port 5 is pivoted a rudder 7 having a rudder post or shaft 8 in parallelism with the depending connection 3 and ordinarily the rudder post 8 is operated by a tiller or tiller mechanism My first improvement is a novel support for the outboard motor which will permit of the. motor tilting or the propeller housing 4 yielding rearwardly when encountering Wreckage or an obstacle. The support includes a boat bracket having clamping arms 9 adapted to be held relative to a boat by clampin screws 10 or other fastening means. Mounted in th outer end of the bracket arms 9 is a shaft 10 having one end thereof supported by one of the arms and the opposite end thereof extending into a reciprocable interlocking member 11 slidable in the other arm.

Adjustable on the shaft 10 is a motor bracket comprising arms 11 suitably attached to the crank case 2 of the motor 1 and said arms are integral with an angularly disposed V-shaped frame 12 having its lower end clamped to the depending connection 3 and affording a guide for the rudder post 8, as shown in Fig. 1.

At the juncture of the frame 12 with the arms 11 are heads 13 and 14 loose on the shaft 10 and held against lateral displace ment by collars 15". The head 14 serves as an interlocking member and has its outer face serrated, toothed or notched, so as to be engaged by a similarly serrated head 15 forming part of the interlocking member 11, and a coiled expansion spring 16 encircles the member 11, between the head 15 and oneof the arms 9 to hold the heads or interlocking members 14 and 15 in engagement with each other. These interlocking members constitute a yieldable 'oint between the motor and boat brackets y which the motor bracket may be held in adjusted positions relative to the boat bracket, the normal position of the motor bracket being in a vertical plane and by virtue of the yieldable joint the motor bracket may tilt relative to the boat bracket. so that the lower portion of the motor may swing rearwardly should the propeller housing 4 or the guard 5 impinge against an obstruction. When such the motor bracket swings on the sh i U and is held by the yieldable interlocking member 11 so that the motor bracket will re main in its tilted position, clearing the ob struction, until again restored to normal po sition. This may be quickly accomplished by operating a cam lever 17 pivotally connected to the outer end of the member it and bearing a ainst the arm 9, as best shown in Fig. 3. y swin 'ng the cam lever 17 upwardly the inter ocking member ii is re tracted, thereby releasin the head or member 14 and permitting the motor to assume normal position by gravity. The normal or vertical position of the motor may be defined by a. stop 18 carried by the boat bracket and adapted to be engaged by the frame 12, as shown in Fig. 1.

My next improvement is a novel steering mechanism for the rudder post 8. Jour naled in the arms of the boat bracket is a transverse shaft 19 having a hand piece 20 and said shaft and its hand piece constitute a rotatable member having its outer ends provided with spools or drums 21. Attached to the spools 21 and wound in opposite directions thereon are cables or flexible members 22 which extend rearwardly and are attached to the ends of the cross head 23 on the upper end of the rudder post 8. It is now ap arent that by rocking or rotating the she t 19 the rudder post 8 may be turned to swing the rudder 7 in a desired direction. The rotatable member orhand piece 20 is in proximity to the motor 1 and does not occupy valuable space in the hull of the boat. It permits of a boat operator placing his back to the motor and with one hand behind the back engaging the hand piece 20 the boat may be steered; this being a distinct advantage forthe convenience of a boat operator which contributes to the pleasure of other occupants of the boat.

It is thought that the utility of my imrovement will be apparent without further description, and while in the drawing there is illustrated a preferred embodiment of each improvement it is to be understood that the structural elements are susceptible to such changes in size, shape and manner of assemblage as fall within the scope of the appended claims.

What I claim is:-

1. The combination of a boat bracket, 8.

direction relative to said heat bracket, said means holding said motor bracket to its swung position, and means coaxial of said members adapted for shifting one of said members to release slid motor bracket from an adjusted position.

2. The combination of a boat bracket, a motor supporting bracket, and co-axially interlocking snap in and out members ada ted to hold said motor bracket at any angl; to which it may be swung.

3. In an outboard motor wherein themotor is supported from a boat with the propellet in a. position liable to encounter obstacles, means for supporting such motor so that it may yield when the propeller encounters an obstacle, said means including interlocking releasable members which hold the motor at any position to which it may be swung by its ropeller encountering an 0bstacle, one 0 said interlocking members being fixed relative to the motor and adapted to rotate relative to the other member which is movable in a lateral direction from said rotatable member.

4. An outboard motor adapted to be pivotally connected to a boat, interlocking mem' bers at the pivot of the motor and adapted to hold said motor in an adjusted position, one of said members being yieldably held relative to another'member and. ads. ted to release said motor from a. shifted position.

5. The combination of a motor, support ing means for said motor so that it may tilt, and co-axial serrated heads adapted to hold the motor to any position to which it may be tilted.

6. The combination of a rudder post, a cross head on the upper end of said post, a boat bracket, a rotatable member iournaled in said boat bracket, spools on the ends of said rotatable member, flexible members connected to the ends of said cross head and reversely wound on the spools of said rotatable inember and means to facilitate rotatin said member.

in testimon whereof I aflix my signature in presence 0 two witnesses.
