United States Patent DUAL CARBURETOR AND IGNITION CONTROL Dewey C. Hildebrecht, Sauk City, Wis. Application February 17, 1953, Serial No. 337,287
6 Claims. (Cl. 123-402 My invention relates to controls for outboard motors and relates more particularly to such controls which may be operated from a point remote from the motor to control both the spark and the carburetor of the motor and thereby to control the R. P. M. of the same.
It is one of the objects of this invention toprovide a remote control for both the spark and carburetor of an outboard motor which may be operated from a remote point in the boat, thereby reducing the hazards ordinarily encountered when the boat is under way and where the operator must move from some remote point to the manual controls of the outboard motor to operate the same directly.
A further object of the invention is to provide a dual control of the type disclosed which is simple of construction and yet will give the same positive control at a remote point that the conventional manual controls will accomplish at the motor itself.
A further object of this invention is the provision of a dual control for outboard motors which may be controlled from a remote point in the boat with extreme ease and smoothness of operation.
A further object of the invention is the provision of means of the above named character which may readily be attached to conventional outboard motors without materially altering the same.
Other objects and advantages of my invention will become apparent from the following description of an embodiment thereof, reference being made to the accompanying drawing in which like reference characters are employed to designate like parts throughout the same.
In the drawing:
Figure 1 is a top plan view of a conventional outboard motor showing my invention employed in use;
Figure 2 is a side elevation of the motor shown in Figure 1;
Figure 3 is a view taken in the direction of line 3-3 of Figure 2;
Figure 4 is a view taken on line 4-4 of Fig. 2;
Figure 5 is a diagrammatic view showing a simplified wiring diagram for operating the controls from a remote point; and
Figure 6 is a view illustrating one of the limit switches which is normally spring closed.
In carrying forward my invention, I have provided means which may be attached to a conventional motor whereby the spark and carburetor of the motor may be controlled independently or together from a point remote from the outboard motor.
The conventional outboard motor illustrated in the drawing is indicated at 1 and includes the usual manual spark control lever 2 which is mounted on the speed control plate and extends beyond the opposite side of the plate terminating in an arm 3. The end of the arm 3 is provided with an elongated slot 4 for receiving a pin 5 which is carried by a ladder chain 6 operating over an idler gear 7 and a driven gear 8. The gear 8 is keyed trolled from a remote point.
to a shaft 9 which, in turn, is driven through a reduction gearing by a reversible electric motor housed within the housing 10 along with the reduction gearing.
By energizing the electric motor in the housing 10 to rotate in either forward or reverse direction, the ladder chain 6 will of course be driven over idler gear 7 and the driven gear 8. The speed control plate and the arm assembly 2 and 3 will be caused to rotate about the axis 11 in one direction or the other depending upon the direction of drive of the ladder chain 6. If desired, limit switches 12 which are normally spring closed may be mounted on the base 13 in the path of movement of the arm 3 to be engaged thereby and to thus break the circuit to the driving motor in the housing 10. In this manner, it is assured that the driving motor will not drive the speed control arm beyond its limit of movement in either direction.
In further carrying out the invention, I provide a carburetor control which like the spark control is also actuated by the operation of a reversible motor con- A reversible motor and a reduction gearing is housed within the motor housing 15. A driven shaft 16 is provided with a crank arm 17 keyed to the shaft 16 and to which at its free end is pivotally connected a link 18. The opposite end of the link 18 is pivotally attached to the end of a lever 19 as at 20. The opposite end of this lever is carried in a bracket 21 mounted on the engine housing and the lever operates about an axis 22 against the compression of a coil spring 23 which normally urges the lever 19 n its lowermost position. Intermediate the ends of the lever 19 is pivotally connected a link 24, the opposite end of this link being pivotally connected to the shaft of a butterfly valve 25 operating in the intake manifold 26 of the engine carburetor.
When the reversible motor in the housing 15 is actuated in one direction, a crank 17 will be oscillated toward one of its extreme positions, and this motion will be transmitted through the link 13, the lever 19 and the link 24 to shift the butterfly valve 25 in the carburetor intake. By reversing the operation of the reversible motor, the parts are moved in an opposite direction to eifect a corresponding movement in the butterfly valve. Limit switches 27 may be provided, if desired, to be actuated by the crank 17 in whose path of movement these switches may be located on opposite sides thereof.
In Fig. 5, a simple control circuit is illustrated diagrammatically, showing the manner of electrically actuating the mechanism from a position remote from the outboard motor. I provide a pair of single pole double throw switches 30 and 31, the former of which controls a circuit through the limit switches 27 to the motor M housed in the housing 15 operating the butterfly valve of the engine. The other single pole double throw switch 31 which may be operated independently of or in conjunction with the first mentioned switch 30 is connected in a circuit to the motor M indicated at 10. In this circuit are also provided the limit switches 12.
Various changes may be made in the details of construction and arrangements of parts without departing from the spirit of my invention or the scope of the appended claims.
