FARRELL [WWW ' ATTORNEYS COMBINED STEERING, SHIFT AND THROTTLE CONTROL FOR OUTBOARD, INBOARD, OR INBOARD- OUTBOARD POWERED BOATS This invention relates to a combined steering, shift, and throttle control for outboard, inboard-rudder or combined inboard-outboard powered boats.

It is the principal object of the present invention to provide a control for outboardor inboard-powered boats in which the shift and throttle control is uniquely embodied in the steering control member and all parts of the control, steering, shift being effected through push-pull cable arrangements and so that the pilot of the boat has a forward station in the boat associated with one upstanding capstan pivotally connected to the bottom of the boat and movable between left and right positions to effect the steering of the boat and bearing the gearshift lever and throttle control upon the same.

It is another object of the invention to provide in an upstanding steering lever of capstan, shift, and throttle levers which are self-contained in casings conforming to the shape of the upper end of the steering lever of the capstan so as to be gravity fitted and mechanically locked into place in the upper end of the capstan yet easily removable therefrom and permitting thereby attaching of the cables to the hand levers, or detaching the same therefrom.

It is another object of the invention to provide a combined steering, shift, and throttle lever control for boats which can be supported from the bottom of the boat either by attachment to the top surface of the floor or depending through the boat floor for connection with cables disposed under the floor and unexposed above the floor of the boat.

It is a further object of the invention to provide a combined steering, shift, and throttle control lever for powered-operated boats that can be adapted for the attachment thereto of different remote control linkages, wires and telemetric hydraulic cylindrical devices and by which the power for steering can e effected through stepped up power means without being dependent upon hand power to effect the steering of the boat.

Other objects of the invention are to provide in the carrying out of the above other objects, a simple construction, inexpensive to manufacture, has a minimum number of parts, easy to install within the boat and connected with the outboard motor or rudder-inboard motor, self-contained holding means for the pivotal steering lever to keep the outboard motor or rudder in its steering position or centered for straight ahead movement of the boat, durable, rugged, of pleasing appearance, efficient and elTective in use.

For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawings, in which:

FIG. 1 is a top perspective view of a boat, with an outboard motor thereon, and utilizing the combined steering, shift, and throttle control lever or capstan and system according to one form of the present invention.

FIG. 2 is an enlarged perspective view of the combined lever or capstan with the throttle and gearshift control devices lifted out of the top of the capstan lever.

FIG. 3 is a vertical sectional view taken on line 3-3 of Fig. 2.

FIG. 4 is a perspective view of a capstan lever constructed according to another form of the invention and adapted for twin outboard motor arrangement.

FIG. 5 is a perspective view of the capstan lever assembly of Figs. 1 to 3 in which the steering linkage employs a bellcrank lever supported for horizontal turning movement on a floor pedestal.

FIG. 6 is a perspective view of the capstan lever shown in Figs. l, 2 and 5 wherein the lower end of the lever extends downwardly through the floor but is pivoted to the top surface of the floor, the steering linkage and the throttle and gearshift cables extending from the lever and under the floor to the outboard motor mounted upon the boat transom.

FIG. 7 is a perspective view similar to Fig. 6 but showing the arrangement ofa bellcrank control lever including the linkage beneath the floor.

FIG. 8 is a top perspective view of the capstan lever pivoted on the top of the floor and employing a telemetric double-acting hydraulic cylindrical actuator for effecting the steering of the outboard motor upon the rear wall of the boat. Referring now particularly to Figs. l3, there is shown a boat indicated generally at 15 having a bottom floor 16 formed of boards and running longitudinally of the boat and a transom l7 witha bracket 18 secured to its upper edge to which an outboard motor 19 is pivotally connected for swinging movement to right or left and having the usual drop propeller and rudder device, not shown, depending into the water and the boat is steered by the turning of the outboard motor to the right or left.

According to the present invention, there is provided a capstan lever 21 which is pivotally connected as shown in the Figs. l3 by a bolt 22 and bolted-down opposing

brackets

24 and 25 to the top surface of the floor 16. The axis of the bolt 22 runs longitudinally of the boat so that the capstan lever 21 is pivoted to the left or right as desired to effect the steering of the outboard motor 13 at the rear of the boat. The capstan lever can be located at any position in the boat and forwardly of the outboard motor. 7

In order to effect steering of the outboard motor, a push pull cable device 26 connected between clamp block assemblies 27 and 28 located respectively on the floor Id of the boat adjacent to the'capstan lever 21 and on the transom 17 of the boat. This cable device comprises an outer sleeve anchored between the block assemblies 27 and 28 and through which a cable wire 29 can be pushed and pulled by the capstan lever. The pull rod 29 is connected by a ball joint device 31 to the rear face of the capstan lever 21. The opposite end of the cable is similarly connected by a ball joint device 32 to a forwardly extending projection 33 of the outboard motor or to the rudder of inboard boats. As the capstan 21 is moved to the left of the pilot the outboard motor is turned to the position shown in Fig. l to cause the boat to be steered to the left. The cable 29 will have been pulled through the cable sleeve and block assemblies 27 and 28 to effect this movement. If the capstan lever is pulled to the right the outboard motor will be swung to the opposite position and the boat is steered to the right. v The outboard motor 19 has a throttle or carburetor control which can be controlled through a throttle push-pull cable device 41, the outer sleeve of which is anchored on the outboard motor 14 and by a clamp 42 on a flaired removable casing 38. The upper end of the capstan lever 2I is flaired upwardly at 39 and is open to removably contain the

removable casings

37 and 38 flaired in shape conforming to the flairing 39 atv the top of the capstan. The width of the

flaired casings

37 and 38 is one-half the width of the flaired end 39 of the lever at the open top thereof and they are shaped so that they can be lowered into the flaired end 39 for a tight fit therein with their upper flaired ends 37 and 38' lying flush with the top edge of the flairing 39 of the capstan lever as best viewed in Fig. 3.

The flaired casing 37 has a depending flange 43 to which the clamp 36 is attached to anchor the cable sleeve. Within the flaired casing 37 and extending out of the top thereof is a shift lever 44 pivotally connected to the casing by a screw 46 and having its lower end connected directly to the pull cable wire 47 of the push-pull cable device 34. The shift lever 44 has a laterally extending handle 38 which is grasped to effect the shifting of gearing by being connected to the outboard motors.

Likewise, the flaired casing 38 has a throttle lever 51 pivoted to the casing at 52 and connected to a cable forming a part of the throttle control so that as the lever 51 is grasped by its handgrip 53 the speed of the motor 19 can be changed.

It should not be apparent that there has been provided a combine steering throttle shift control capstan lever by which the boat 15 can be controlled through its outboard motor and wherein by the provision of

insertable casings

37 and 38 for the hand levers 44 and SI the cables can be easily secured thereto or taken up with the casings being made free for this purpose by being removable from the flaired upper end 39 of the lever. It should now be apparent that this same capstan control lever with the throttle and gearshift controls can readily be connected to rudder for the boat and the controls connected to an inboard motor or the outboard part and the controls to the inboard part of an inboard-outboard motor.

With the

casings

37 and 38 thrust tightly into the flaired upper end 39 and mechanically fastened to the lever 21 by the push-pull cable being substantially frictionally resisted the pilot can grasp particularly the throttle lever handgrip 53 to effect the steering of the outboard motor to the right or left. The pressure is being applied upon the handgrip lever 51 more to the side than longitudinally so that the movement of the capstan lever 21 can be effected without changing the throttle lever 51 between its highand low-speed position. The movement to which the capstan lever can be extended to effect the steering is illustrated by dot-

dash lines

56 and 57 of Fig. 3.

It will be apparent that in this arrangement push-pull cables have been used throughout and that any movement of the levers will effect the ad justments and the push-pull wire retained in the sleeve through its frictional engagement therewith will hold the parts in their adjusted positions. An instrument panel 55 may be formed upon the front of the flaired upper end 39 of the capstan lever 21 and may contain gages 55' and side switches 55'. In this manner complete control of the boat for starting, ignition, lights, checking the running condition of the motor, monitoring the instruments and so forth will be provided upon the capstan lever.

If it is desired to use a push rod linkage, the capstan lever 21 can, as shown in Fig. 5, be connected by a bellcrank lever 58 mounted on the upper end of a post 59 fixed upon the floor 16 and connected for lateral pivotal movement on a pivot pin 61 at the upper end thereof. A ball joint 31' on the capstan lever is connected by a push rod 62 and a bifurcated connection 63 to one arm 64 of the lever 58 while the other arm 65 is connected by a bifurcated connection 66 to the telescopic end of a rod or hydraulic cylinder device 67. The opposite end of the rod 67 will be connected through a similar linkage to the forwardly extending steerable motor projection 33. Steering is thus effected with this arrangement in the same manner as above described by moving the capstan lever 21 to the right or left.

In Fig. 6, the lower end of the capstan lever 21 is depended through a hole 68 in the floor 16 so that the pivot bolt 22 will be raised upon the lever 21 and supported in the same manner as above described by

brackets

24 and 25. The ball joint device 31 is connected to the lever 21 under the floor 16 to a straight lever 69 pivoted on the lower end of a support 71 depending from the underside of the floor l6. The rod 67 is connected to the opposite end of the lever 61 and by a similar linkage to the outboard motor or rudder projection 33.

In Fig. 7, there is a similar connection of the capstan lever 21 through opening 68 in the floor 16 in which the linkage is provided under the floor 16 but in which a reverse bellcrank lever 58 is used, the same being pivoted on the lower end of a support 71 depending from the floor 16..The outer arm 72 is secured to the bifurcated connection 66 of the linkage end 67. The capstan lever 21 having the throttle and shift levers 51 and 44 will be operated in the manner above described to effect the control of the boat.

In Fig. 8, a telemetric hydraulic arrangement indicated generally at 75 employing two-way hydraulic

cylindrical devices

76 and 77. The hydraulic cylindrical device 76 is mounted on a post 78 extending upwardly from the floor 16 and is further connected by a ball joint rod 79 with the capstan lever 21 pivoted upon pivot pin 22 in

brackets

24 and 25 secured to the top of the floor 16. As the capstan lever 21 is moved to the right or left the ball joint connection 31 moves the rod 79 and its piston within the hydraulic cylindrical device 76 to force hydraulic fluid through either

hose connection

81 or 82 to effect upon the hydraulic cylindrical device 77 the movement of its piston and rod 83 upon the balljoint connection 84 with the forwardly extending projection 33 of the outboard motor 19. The movement of the capstan lever 21 to right or left will cause a corresponding turning of the outboard motor 19 upon its pivotal bracket 18 on the transom 17 of the boat.

In Fig. 4, there is shown a modified capstan lever 86 that is pivotally and similarly secured to the floor 16 by pivot bolt 22 and

brackets

24 and 25. The upper part of the capstan lever 86 while being flaired at its top 89 is closed at the top at 91 upwardly from which there extends a handgrip 92 which is grasped by the pilot to pivot the capstan lever 86 to the right or left. Instead of casings being removable out of the flaired upper end 89 of the lever 86,

dual lever casings

93 and 94 are connected respectively to the opposite sides of the capstan lever 86. These

housings

93 and 94 contain single-lever shift and throttle control handles 96 and 97 and adapted for controlling the operation of twin outboard or inboard motors. Push-pull cable devices 101 and 102 extend from the control housing 94 and capstan lever 86. A ball joint connection 31 connects the lever 86 with a telescopic end of a pullcable or hydraulic cylinder device as above described.

It should now be apparent that with the various arrangements as they are worked out for connection between the capstan lever and the outboard or inboard motors that full control of the outboard or inboard motors can be completely efi'ected through the capstan lever located anywhere in the boat or even on an upper lever known as a flying bridge. It is apparent that the capstan lever is connected to the rudder where inboard motors are used or to the outboard part of an inboardoutboard type of motors.
