Application June 3, 1933, Serial No. 674,225

11 Claims. (01.123-185) of snapping a whip, and is apt to hit other occupants in the boat.

Therefore, an object of this invention is the provision of simple and eflicient means for preventing the inner end of the rope from leaving the motor until lifted off, and in no case apt to fiy off and hurt occupants of the boat, or cause operator to lose balance by reason of sudden release of end of rope.

Another object of the invention is a novel device or adapter for attachment as a unit to the motor shaft of an outboard motor, whereby the starting rope is detachably secured thereto,

. against accidental displacement.

A'still further object of the invention is the provision of means, in an outboard motor ropeattaching device, for carrying a supply of the ordinary brass shear pins for attaching the propeller.

, In the drawing:

Figure 1 is a view in side elevation of a device constructed in accordance with the present invention, showing rope in position, ready for starting motor, while 3 Figure 2 is a top plan view of the same.

Figure 3 is a vertical central sectional view of the post or adapter device, showing the same secured to a nut on the outer end of the motorshaft, and showing brass shear pins loosely contained inside;

Figure 4 is an enlarged view of the bottom or inner end of the adapter device, showing broaching to fit hexagon nut on end of motor shaft.

Figure 5 is a fragmentary view in side elevation of the propeller and propeller shaft of an outboard motor, showing brass shear pin in place.

Referring to the drawing by numerals, 1 designates the propeller shaft of an outboard motor.

I On the outer end of shaft 1 is the propeller hub 4;

this hub is secured on said shaft by a brass shear pin 5. 2 is a nut which assists in securing the fly wheel 3 on motor shaft. The fly wheel is provided with the usual flange 6 having the ordinary rope-receiving notch 7. The rope 8 extends through notch '7 and is adapted to be wound upon the fly wheel, in groove 9 (Fig. 1) under the flange 6, when it is desired to rotate or spin the motor for the purpose of starting the same.

The term rope is used in this specification and the appended claims in a broad sense, meaning any kind of .means that would perform the same function, such, for instance, as a flexible cable, etc.

My novel device comprises the post or adapter device 10, ring device 11 and rope 8. The adapter device 10 comprises a hollow body 12 (Fig. 3) which has at its bottom or inner end a nut-receiving socket l3 and is internally threaded and tapered at its top or outer end. A hollow cap 14 is threaded into the outer end of the body 12 this cap is provided with a knurled flange 15,. producing an auxiliary shoulder 16, Intermediate the ends of the body 12,, is a primary groove 1'7, which has an annular primary shoulder 18. Between'shoulder 18 and shoulder 16 the reduced body 12 con'stitutesan auxiliary groove 19. A set screw 20 is employed to engage nut 2 and thereby fixedly. secure the adapted device assembled with the motor shaft, so that said post or adapter 80. device'and shaft rotate synchronously. It will be apparent that upon loosening set screw the operator can quickly remove or lift the, adapted device. The nut-receiving socket 13 can be made of any desired shape and size to accommodate various types of nuts on various motors.-, The bottom or inner end of adapter may be fitted with flange or other means of fastening to flywheel when nonut protrudes through. Further, the hollow structure of the body 12, cap 14, and; the top'of nut 2 produces an admirable compart ment or container 21, in which a supply of the brass shear pins 5 can be stored. This isa great convenience, because the operator will have ready at hand a sufficient supplyof thepinsb.

The ring device ll comprises,a'large-primary eye 22 and a small auxiliary eye 23. The rope 8 is suitably fastened or secured to the auxiliary eye 23. On the outer end of the rope is a grip 24. The primary eye 22 is sufficiently large to readily pass over the top or outer end of the adapter device and then be seated in the primary groove 1'7, bearing against the shoulder 18 thereof. To start the motor, the rope is wound around the grooved portion of the fly wheel, thereby holding the ring device securely in position upon the adapter device, with a portion of the rope extending through notch 7. When the rope is so positioned, the operator pulls on the grip 24 to quickly rotate the fly wheel, thereby spinning the motor; when the rope is unwound by this operation, the ring device 11 still remains upon the adapter device and usually the primary eye is in the groove 17. However, if the primary eye 22 should jump over shoulder 18, it then rides in the auxiliary groove 19 against shoulder 16. It has been found from extensive experience that the ring device rarely jumps out of groove 17 during the operation, but that in those rare instances in which it does, the ring device is efiiciently kept from com ing entirely off the adapter device by the flange 15 of the cap 14. Hence, there are two retaining means for the ring device on the adapter 'device, insuring against accidental displacement of the inner end of the starting rope from-off the adapter device.
