CORPORATION 01? NEW JERSEY STARTER FOR INTERNAL-COMBUSTION MOTORS 01181181 No. 1,700,750, dated February 5, 1929 Serial No. 215,073, filed August .24, 1927. Application [or reissue filed February 3, 1931.

This invention relates to startin means for internal combustion motors an has in view in particular to provide a starting means for so-called kickers, or outboard motors used in propelling small boats which may be applied to existing types of such motors without considerable change in their construction and which shall be simple, reliable, and easily operated.

Given the rotary element (of the internal combustion motor) to be started and provided with a clutch portion, my invention broadly contemplates the combination therewith of an electric circuit having a source of 1.: energy and also a break therein, an electric motor in the circuit, and means shiftable to close the circuit and thereupon transmit rotation from the motor to said element includinga clutching member driven by the motor and shiftable as a part of said means into.

clutching engagement with said clutch portion of the latter. In the specific embodiment herein set forth, said means also in-v cludes, with said member, a device whose special function it is to close the circuit as well as cause the shifting of said member. In the simplest and otherwise best formthe clutching member is coaxial with said'element and shiftable lengthwise of its axis. a

3 In the drawings, a

Fig. 1 is a side elevation of'a motor having my starting means and applied to a boat, w ich part y appears, in section; 15 Fig. 2 is a plan, the boatbeing omitted;

Fig. 3 shows the principal parts of my invention on a larger scale and mainly in section; 1

Fig. 4 is'asection on line 44, Fig. 3 and Fig. 5 shows a detail. At the rear of the boat 1 is mounted the internal combustion motor or kicker 2, with its main or pro eller shaft 3 u right, such motor as shown eing of a well known type. The shaft 3 has suitably aflixed on its upper end the fly-wheel 4, and they together form Serial No. 613,237.

the aforesaid rotary element of the motor, the remaining parts of which, being well known and having no particular bearing on the present invention, require no description herein. The shaft 3 usually has a threaded upper end 311 protruding from the flywheel and receiving a nut which bears upon the latter. In place of this nut I screw on said threaded end 3a a tubular shaft-extension or post 5 having a top wall with a central opening 51) therein.

On said rotary element is secured a clutchpiece 6, here shown held to the fly-wheel by cap-screws 7 Also on said element but revoluble and also longitudinally 'shiftable thereon is the aforesaid rotary member driven by the electric motor; in the present example this comprises a clutch-piece 8 (to engage clutch-piece 6) having a threaded major extension 8a, a sprocket-wheel 9 screwed fast on the extension 8a, and a lock-nut 10 (to se-' cure the sprocket in place) screwed on a further or minor and reversely threaded (Fig. 5) extension 8?; of the clutch-piece 8. Said member and element together aflord a housing 11 (around the protruding part of the shaft) and this contains a spiral spring 12 which normally holds the clutching portion of said member clear of that of said element, as shown in Fig. 3. Assuming said rotary member to be driven, on forcing the same toward the fly-wheel said member and ele-. ment will be clutched together and the lat ter driven by the former.

The clutching member formed by the sprocket wheel and its clutch-piece 8 is driven, through a chain 13, by a sprocket wheel-14 .on or forming apart of the rotor of an electric motor 15 which it will-be convenient to mount in a bracket 16 projecting from a fixed part, as the casing, of the motor 2. This motor is in a circuit 17 having a source of electric energy 18 and a break (to be indicated in the circuit).

For closing the circuit and shifting said through opening 51) thereof andits head 20a below wall 5a and so retaining the knob in place. The stem of the knob is seated on a spiral spring 22 housed in the shaft-extension,,and of less resistance than spring 11. Collar 21 forms one terminal of the mentioned circuit and some other metal part of the mechanism normally insulated from the collar by the flange 190 may form the other terminal, leaving (normally) the aforesaid break in the circuit at 23, Fig. 3.

When the means including the knob (which is in efiect swivelled on said rotary element) and said clutching member is shifted downwardly as by pressure being exerted on the knob until it contacts with and then depresses said member, the circuit will be closed (starting the motor 15) and the clutching portions engaged with each other, whereby the motor 15 will impart rotary impulse to the motor 2'to start the same.

Having thus fully described my invention, what I claim is:

1. In combination, the rotary element to be started rotating and having a clutch fportion, an electric circuit having a source 0 energy and also a break therein, an electric motor 1n the circuit, a rotary clutching member driven by the motor and shiftable into clutching enagement with said clutch portion, and a ob coaxial with said element and movable len hwise of its axis to close the circuit and shi said member into such engagement.

2. In combination, the rotary element to be started rotating and having a clutch portion, a rotary clutching member, means to rotate said member, said member being shiftable into clutch-engagement with said portion to start said element rotating, and a knob movable to cause such shifting of said member swivelled andarranged concentrically with respect to said element.

3. In combination, the rotary element to be started rotating and having a clutchportion and an extension projectin centrally of said portion, a clutching mem r revoluble on said extension and shiftable thereon into and out of interlocking engagementwith said portion, a drivin motor, a circuit to said motor, a switch e ement in said circuit, and means for moving said switch element into contact with said clutching member to energize saidmotor and, by the pressure of such contact, shift said clutching member into en;

gagin position. a,
