United States Patent 3,146,632 SPEED AND CLUTCH CONTROL DEVICE INCLUD- ING AUXILIARY MEANS FGR ADVANCING ENGINE SPEED Finn T. kgens, Milwaukee, Wis., assignor to ()utboard Marine Corporation, Waukegan, 111., a corporation of Delaware Filed Mar. 22, 1962, Ser. No. 181,718 23 Claims. (Cl. 74-472) The invention relates generally to speed and shift control devices for engines such as internal combustion and turbine engines. More particularly, the invention relates to single lever speed and shift control devices for engines incorporating electrically actuated shift or clutch means. Still more particularly, the invention relates to arrangements for permitting advancement of an engine throttle setting when such clutch means is in neutral, whereby the engine can-be readily warmed up before being placed under load.
The invention herein disclosed constitutes a further development of the control device disclosed in the Shimanckas application entitled Single Lever Electrical Control, Serial No. 177,018 filed March 2, 1962, and assigned to the assignee of this application.
The invention provides for advancement of the throttle by an auxiliary control member without recourse to shifting of an inner core relative to an outer sleeve of a pushpull cable, as disclosed in said copending application. Specifically, the invention provides an auxiliary control member which is movably mounted on the frame of the device and is connected to a throttle adjusting arm, such as the arm indicated by reference numeral 41 in the Shimanckas device referred to above, for the two-fold purpose of affording throttle adjusting movement of the arm incident to movement of the main control lever and of affording throttle adjusting movement of the arm incident to movement of the auxiliary control member when the main lever is in a predetermined position. Thus, there is provided an arrangement for advancing the engine throttle setting, preferably through a limited range, when the main control lever is in its neutral position.
The principal object of the invention is the provision of a control device of the type generally referred to above, which device includes an arrangement for controlling the engine throttle setting, at least through a limited range, independently of any movement of the main control lever. Another object of the invention is the provision of such a control device in association with a boat having mounted thereon an engine adapted for propulsion thereof. Other objects and advantages of the invention will become known by the following description and the accompanying drawings of one embodiment. In the drawings:
FIGURE 1 is a fragmentary view, partially in section and partially diagrammatic on a reduced scale, of a boat incorporating a control device in accordance with the invention;
FIGURE 2 is a fragmentary sectional view taken generally along line 22 of FIGURE 1; and
FIGURE 3 is a view similar to FIGURE 1 showing the device with the auxiliary control member positioned to effect limited throttle advancement when the clutch means is in neutral.
The speed and clutch control device 11 illustrated in FIGURE 1 is one example of various arrangements that can be employed for engine control. The device 11 is mounted on the hull 12 of a boat and is intended for control of an engine 13 (shown schematically) having an adjustable throttle 15 and an electrically actuated clutch 17 including a pair of energizable coils 19 and 21, for enabling operation of the engine in neutral, in forward drive, and in rearward drive. Forward drive of the engine 13 is provided incident to energizing of the coil 19 and rearward drive is provided incident to energizing of the coil 21. When neither of the coils 19 and 21 is energized, the engine 13 is in neutral. .However, the invention in its broader aspects is not limited to control of an engine having an electrically operated clutch.
One example of an engine incorporating an electrically actuated reversing clutch is fully disclosed in the copending Shimanckas application entitled Marine Propulsion Device With Electromagnetic Reversing Clutch, Serial No. 143,773, filed on October 9, 1961, and assigned to the assignee of this application.
In the disclosed device 11, as already discussed in the first-mentioned Shimanckas application, a main control lever 23 is pivotally mounted on a frame 25 for control, incident to pivotal movement thereof, of a pair of elec trical switches 2'7 and 29, which switches are mounted on the frame 25 and are respectively connected to the coils 19 and 21. Adjustment of the engine throttle setting incident to movement of the main control lever 23 is provided by the inclusion in the control lever 23 of a cam slot 31 in which there is engaged a follower 33 mounted on an arm 35. The arm, in turn, is pivotally connected, at its lower end, to an anchor block 37 which is fixed to one end of the core 39 of a push-pull cable 41 connected at its other end to the engine throttle 15. Accordingly, movement of the lower end of the arm 35 in directions lengthwise of the anchor block will effect adjustment of the engine throttle setting.
As set forth in said co-pending application Serial No. 177,018, the cam slot 31 is designed to maintain the throttle at an idle setting when the main control lever 23 is in its neutral position and during movement through both shift ranges. Thus, advancement of the throttle is prevented until after shifting of the engine clutch from neutral to forward or rearward drive.
In the first-mentioned Shimanckas application, the arm was pivotally mounted on the frame so that throttle adjusting movement thereof occurred in response to pivotal movement of the main control lever. In the disclosed construction, the arm 35 is mounted so as to provide throttle adjusting movement thereof in response to movement of the main control lever 23 and, in addition, to afford throttle controlling movement independently of any movement of the main control lever 23, as for instance, when the main control lever 23 is in its neutral position. Specifically, in the disclosed construction, the arm 35 is pivotally mounted to an auxiliary control memher or lever 43 by a stud 42. In turn, the auxiliary arm 43 is pivotally mounted on the frame 25 about a pivot 44 located in spaced relation to the pivotal connection of the arm 35 to the auxiliary lever 43. Preferably, the mounting on the frame 25 of the auxiliary lever 43 relative to the pivotal connection between the auxiliary lever 43 and the arm 35 is such as to effect a minimum of movement of the cam follower 33 in the cam slot 31 incident to movement of the auxiliary lever 43, and a maximum of pivotal movement of the adjusting arm 35 about the axis of the follower 33 in the cam slot 31. By comparison of FIGURES 1 and 3, it will be seen that when the main control lever 23 is in neutral, movement of the auxiliary lever 43 from its slow idle position (FIG- URE 1) to its fast idle position (FIGURE 3) effects advancement of the engine throttle setting by displacement to the left of the anchor block 37.
