OUTBOARD MOTOR CONTROL Filed Feb. 18, 1949 2 Sheets-Sheet 2 ML mm B //A W/fl/VS Altar/Ivy Patented Oct. 24, 1950 UNITED: STATES" PATENT OFFICE I I I 2,526,946 oUTBo Rn oron CONTROL William.P.;Hawk ins, El Paso, Tom I Application February 18, 1949, Serial No. 77,194-

Generally there is provided a one-hand control a:

foroutboard motors in which a single handle is .utilized and which is pivoted in such manner that vertical movement of the handle will cause a regulation of the ignition and fuel control while horizontal movement of the handle will steer a boat to which the motor is attached in the conventional manner.

It is accordingly an object of the invention to provide a device of the character set forth which is simple in its construction and operation and yet effective and efficient in use.

Another object of the invention is the provision of novel means for controlling a combination fuel and ignition lever.

Another object of the invention is the provision of a novel arrangement of linkages and levers for effecting the above-mentioned object.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure 1 is a fragmentary perspective view of an embodiment of the invention,

Figure 2 is a plan view of Figure 1,

Figure 3 is an elevational view of the device as shown in Figures 1 and 2,

Figure 4 is an enlarged fragmentary sectional view illustrating certain details of the invention,

Figure 5 is a plan view, partly broken away, illustrating certain details of the invention,

Figure 6 is an exploded perspective view showing certain elements of the invention, and

Figure '7 is a perspective view of an element of the invention.

Referring more particularly to the drawings, there is shown therein an outboard motor generally indicated at In and provided with conventional clamps II for affixing the same to the stern of a boat l2 and provided with the conventional fly wheel I3 and combination ignition and carburetor control lever I4.

A U-shaped trough I5 is afiixed in angular relation to the upper side of the lever I4 and within the recess of the trough member I5 there is mounted for slidable movement a detent I6 of an upper arm I! of a vertically extending revoluble shaft I8.

A hearing l9 surrounds the detent I6 within the trough I5. The lower end of the shaft I8 has integrally formed therewith a laterally ex- 3 Claims. (Cl. 11518) tending arm 20 to which is pivotally connected, as indicated at 2|, the inner end of a link 22 Whose outer end is pivotally connected to a bracket 23 as indicated at 24.

The shaft I8 is pivotallymounted in a bracket 25 carried by the motor I0 which latter is also provided with the conventional steering handle 26. To the upper end of which is pivotally connected, as indicated at 21, a vertically movable control handle 28. I

The operation of the device is exceedingly simple in that the vertical positioning of the handle 28 causes a relative horizontal movement of the lever l4 to thereby control the carburetor and ignition of the motor I0. This is effected in the following manner: Upward movement of the arm 28 will cause an inward movement of the link 22 thereby causing the arm 20 to rotate clockwise as viewed in Figure 1, for example, thereby moving the shaft l 8 in aclockwise direction and consequently the arm I! in a clockwise direction. This movement in turn will cause a movement of the lever I4 to the left as viewed in Figure 1 through the pressure of the detent and its bearing I9 against the sides of the trough I5. A downward movement of the lever 28 will cause a reverse of the movements of the motor just described. Hence, any movement of the handle 28 will cause a consequent movement of the lever I4 to thereby control the operation of the motor. Again, a horizontal movement of the arm 23 will cause a like movement of the steering arm 215 to pivot the entire motor structure in conventional manner to thereby steer the boat l2. A leaf spring 30 is affixed to the arm 26 by means of a bolt 3| or the like and projects outwardly from the under side thereof and a screw 32 is vertically mounted in the arm 26 adjacent the outer end thereof and has its lower end bearing against the upper face of the spring 30 to thereby regulate the tension of the same. The outer end of the spring 30 bears against the inner end of the handle 28 to normally urge the same into a horizontal position.

It will thus be seen that there is provided a control wherein the operator of an outboard motor may utilize but a single hand whereby to control the speed, starting, stopping and steering thereof.

While but one form of the invention has been shown and described herein it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or th scope of the appended claims.

What is claimed is:

l. A device of the character described comprising the combination with an outboard motor having a carburetion and ignition lever and a steering lever, of means for simultaneously operating both of said levers, said means including a vertically pivoted handle for the steering lever, a trough-like member aflixed angularly upon the carburetion and ignition lever, a vertically extending shaft carried by the motor, an upper arm aifixed to the shaft, a dependent detent at the outer end of the upper arm slidably mounted in the trough-like member, a lower arm affixed to the shaft and a link interconnecting the lower arm and the handle.

2. A device of the character described comprising the combination with an outboard, motor having a, carburetion and ignition lever and a steering lever, operating both said levers, said means including a vertically pivoted handle for the steering lever, a trough-like member afiixed angularly' upon the carburetion and ignition lever, a vertically extending shaft carried by the motor, an upper arm affixed to the shaft, a dependent detent at the other end of the upper-arm slidably mounted in the trough-like member, a lower arm affixed to the shaft and a bracket aflixed to the handle and a link interconnecting the bracket and: said lower arm.
